Cruise control is an invaluable feature on Ameri­can ­cars. Without cruise control, long road trips would be more tiring, for the driver at least, and those of us suffering from lead-foot syndrome would probably get a lot more speeding tickets.

­Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart. With traffic continually increasing, basic cruise control is becoming less useful, but instead of becoming obsolete, cruise control systems are adapting to this new reality -- soon, cars will be equipped with adaptive cruise control, which will allow your ­car to follow the car in front of it while continually adjusting speed to maintain a safe distance.

In this article, we'll learn how a conventional cruise control system works, and then we'll take a look at adaptive cruise control systems that are under development.

What Cruise Control Does

Cruise control acceleration and deceleration, controlling the cruise control, adaptive cruise control.

The cruise control system actually has a lot of functions other than controlling the speed of your car. For instance, the cruise control pictured below can accelerate or decelerate the car by 1 mph with the tap of a button. Hit the button five times to go 5 mph faster. There are also several important safety features -- the cruise control will disengage as soon as you hit the brake pedal, and it won't engage at speeds less than 25 mph (40 kph).

The system pictured below has five buttons: On, Off, Set/Accel, Resume and Coast. It also has a sixth control -- the brake pedal, and if your car has a manual transmission the clutch pedal is also hooked up to the cruise control.

• The on and off buttons don't actually do much. Hitting the on button does not do anything except tell the car that you might be hitting another button soon. The off button turns the cruise control off even if it is engaged. Some cruise controls don't have these buttons; instead, they turn off when the driver hits the brakes, and turn on when the driver hits the set button.
• The set/accel button tells the car to maintain the speed you are currently driving. If you hit the set button at 45 mph, the car will maintain your speed at 45 mph. Holding down the set/accel button will make the car accelerate; and on this car, tapping it once will make the car go 1 mph faster.
• If you recently disengaged the cruise control by hitting the brake pedal, hitting the resume button will command the car to accelerate back to the most recent speed setting.
• Holding down the coast button will cause the car to decelerate, just as if you took your foot completely off the gas. On this car, tapping the coast button once will cause the car to slow down by 1 mph.
• The brake pedal and clutch pedal each have a switch that disengages the cruise control as soon as the pedal is pressed, so you can shut off the cruise control with a light tap on the brake or clutch.

The cruise control system controls the speed of your car the same way you do -- by adjusting the throttle position . But cruise control actuates the throttle valve by a cable connected to an actuator , instead of by pressing a pedal. The throttle valve controls the power and speed of the engine by limiting how much air the engine takes in (see How Fuel Injection Systems Work for more details).

In the picture above, you can see two cables connected to a pivot that moves the throttle valve. One cable comes from the accelerator pedal, and one from the actuator. When the cruise control is engaged, the actuator moves the cable connected to the pivot, which adjusts the throttle; but it also pulls on the cable that is connected to the gas pedal -- this is why your pedal moves up and down when the cruise control is engaged.

Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. This works in a similar way to the brake booster , which provides power to your brake system.

The brain of a cruise control system is a small computer that is normally found under the hood or behind the dashboard. It connects to the throttle control seen in the previous section, as well as several sensors. The diagram below shows the inputs and outputs of a typical cruise control system.

A good cruise control system accelerates aggressively to the desired speed without overshooting, and then maintains that speed with little deviation no matter how much weight is in the car, or how steep the hill you drive up. Controlling the speed of a car is a classic application of control system theory . The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage.

The most important input is the speed signal; the cruise control system does a lot with this signal. First, let's start with one of the most basic control systems you could have -- a proportional control .

In a proportional control system, the cruise control adjusts the throttle proportional to the error, the error being the difference between the desired speed and the actual speed. So, if the cruise control is set at 60 mph and the car is going 50 mph, the throttle position will be open quite far. When the car is going 55 mph, the throttle position opening will be only half of what it was before. The result is that the closer the car gets to the desired speed, the slower it accelerates. Also, if you were on a steep enough hill, the car might not accelerate at all.

Most cruise control systems use a control scheme called proportional-integral-derivative control (a.k.a. PID control). Don't worry, you don't need to know any calculus to make it through this explanation -- just remember that:

• The integral of speed is distance.
• The derivative of speed is acceleration.

A PID control system uses these three factors -- proportional, integral and derivative, calculating each individually and adding them to get the throttle position.

We've already discussed the proportional factor. The integral factor is based on the time integral of the vehicle speed error . Translation: the difference between the distance your car actually traveled and the distance it would have traveled if it were going at the desired speed, calculated over a set period of time. This factor helps the car deal with hills, and also helps it settle into the correct speed and stay there. Let's say your car starts to go up a hill and slows down. The proportional control increases the throttle a little, but you may still slow down. After a little while, the integral control will start to increase the throttle, opening it more and more, because the longer the car maintains a speed slower than the desired speed, the larger the distance error gets.

Now let's add in the final factor, the derivative . Remember that the derivative of speed is acceleration. This factor helps the cruise control respond quickly to changes, such as hills. If the car starts to slow down, the cruise control can see this acceleration (slowing down and speeding up are both acceleration) before the speed can actually change much, and respond by increasing the throttle position.

Two companies are developing a more advanced cruise control that can automatically adjust a car's speed to maintain a safe following distance. This new technology, called adaptive cruise control , uses forward-looking radar , installed behind the grill of a vehicle, to detect the speed and distance of the vehicle ahead of it.

Adaptive cruise control is similar to conventional cruise control in that it maintains the vehicle's pre-set speed. However, unlike conventional cruise control, this new system can automatically adjust speed in order to maintain a proper distance between vehicles in the same lane. This is achieved through a radar headway sensor , digital signal processor and longitudinal controller . If the lead vehicle slows down, or if another object is detected, the system sends a signal to the engine or braking system to decelerate. Then, when the road is clear, the system will re-accelerate the vehicle back to the set speed.

The 77-GHz Autocruise radar system made by TRW has a forward-looking range of up to 492 feet (150 meters), and operates at vehicle speeds ranging from 18.6 miles per hour (30 kph) to 111 mph (180 kph). Delphi's 76-GHz system can also detect objects as far away as 492 feet, and operates at speeds as low as 20 mph (32 kph).

Adaptive cruise control is just a preview of the technology being developed by both companies. These systems are being enhanced to include collision warning capabilities that will warn drivers through visual and/or audio signals that a collision is imminent and that braking or evasive steering is needed.

Cruise Control: What It Is and How to Use It

How to use cruise control.

The location of the cruise control buttons can vary per car. For your car, check the manufacturer’s manual for the location and specific instructions. To set cruise control, press the ON/OFF button or switch. If you press this button again, it typically turns the system off. The Res + (resume / increase seed) button increases the cruising speed by 1 mph, while the Set – (set speed / reduce speed) button decreases it by 1 mph. To shut off the cruise control, you can press the Cancel button or simply press the brake pedal. [1]

What is cruise control?

Cruise control locks your car’s accelerator at a specific speed, allowing you to take your foot off the pedal and remain at a constant speed. Because it’s so convenient for commuters and drivers who use the highway frequently, cruise control is a feature that generally comes standard on most models of cars. [2]

What is adaptive cruise control?

Adaptive cruise control is very similar to conventional cruise control, only it automatically adjusts the speed of your vehicle depending on how fast the vehicle in front of you is going. It may also reduce your speed around tight curves and adjust to speed limit changes, depending on your car’s technology. [3]

How to set cruise control

Follow these steps when setting the cruise control:

• Evaluate weather conditions: Check for hazardous weather conditions and any oncoming obstacles before applying cruise control.
• Build your speed: The ideal speed for cruise control is between 55 and 70 mph.
• Turn cruise control on: The button is usually on or near your steering wheel.
• Set cruise control: Press another button on your steering wheel and remove your foot from the accelerator.
• Watch the road carefully: You will have a slower reaction time if your foot is off of the brake or accelerator pedal. [1]

How does cruise control work?

Cruise control adjusts the throttle position in your car to control your speed. It does this by a cable connected to an actuator, instead of just by pressing the pedal to adjust the speed. [4]

Cruise control safety tips

Follow these safety tips while using cruise control on the road:

• Use it only on highways: Roads with lower speeds often have traffic lights, turns and other cars that require frequent stops.
• Don’t use it in heavy traffic: If you hit traffic and use the brakes a lot, cruise control isn’t ideal.
• Don’t use it on wet streets: Wet roads are dangerous, and it’s important to keep control of your car and its speed in those conditions.
• Keep your distance from other cars: A set speed could cause you to get dangerously close to other vehicles. Not every car as the distance-monitoring system that adjusts your car’s speed based on what’s in front of you.
• Hover your foot over the brake: Always be prepared to break whenever necessary.
• Be aware of your surroundings: Look out for other cars on the road and stay in your lane. [5]

Cruise control when it’s raining

Avoid using cruise control when the roads are wet . You might not be able to stop as quickly as you’d like when using cruise control. This could lead to dangerous situations and even accidents. Wet roads can affect your car’s ability to maintain a constant speed. There’s even a possibility if you’re using cruise control while it’s raining that your vehicle could hydroplane . [6]

Frequently asked questions about cruise control

Does cruise control save gas.

Cruise control can help you save an average of 7% to 14% on gas. When you don’t use cruise control and constantly press the accelerator and brake pedals, more gas is usually used. Cruise control works best to save gas when driving on flat roads that are free of congestion. [7]

Is cruise control bad for your card?

In general, cruise control isn’t bad for your car. It can actually reduce heavy acceleration and deceleration. It doesn’t damage your car in any way, and the frequent use of it doesn’t affect your vehicle. [8]

Is cruise control safe?

Cruise control is convenient for long stretches of driving and it can keep you from speeding if you set your speed to the correct limit. However, if the road conditions are rainy or snowy, cruise control can be dangerous. To use cruise control safely, it’s best to know when you should and shouldn’t use it. [9]  Using cruise control on the highway makes your driving more predictable to other drivers.  Instead of constantly changing speeds, cars know how fast you’re driving and can follow safely behind you or pass.

When should cruise control not be used?

You shouldn’t use cruise control in the following conditions:

• When the roads are wet and slippery.
• During heavy traffic.
• On hills and winding roads. [9]

Cruise Control In Cars Explained (And How To Safely Use It)

Have you ever wished you could set your car's speed and just sit back and relax while driving on a long stretch of highway? If that's the case, then cruise control is just the ticket you've been searching for—and the good news is, it's a standard feature in most cars these days!

Cruise control is a handy feature for drivers that allows you to maintain a constant speed without having to keep your foot on the gas pedal. In this post, we'll explore how cruise control works, its benefits, and how to use it safely to make your driving experience more comfortable.

Understanding Cruise Control

Cruise control, also known as speed control, is an electronic system that allows you to maintain a specific speed without manually controlling the accelerator pedal. The system uses sensors and electronic components to control the throttle and keep your car moving at a desired speed. First introduced in the late 1950s, cruise control has since become a standard feature in most modern vehicles you see on the road today.

How Does It Work?

At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed. If the car begins to slow down because of an incline (e.g. going up a hill), the system will open the throttle to accelerate. Conversely, if the car starts to speed up due to a declin (e.g. going downhill), the system will close the throttle to decelerate.

Modern cruise control systems also come with additional features like adaptive cruise control (ACC), which uses radar or cameras to detect vehicles ahead and automatically adjusts the speed to maintain a safe following distance (more on this BELOW).

The History of Cruise Control

The invention of cruise control can be traced back to the late 1940s and early 1950s, when engineer Ralph Teetor developed the first-speed control system. This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control.

Types of Cruise Control Systems

Today, drivers can choose from a range of cruise control systems, each with its own unique features and functionalities.

Conventional Cruise Control

Conventional cruise control is like your old reliable friend. It's pretty basic and doesn't have any fancy bells and whistles. You just set the speed you want, and it'll keep your car cruising along at that speed, no problem. It's perfect for those long drives on open highways, but it doesn’t automatically react to other cars on the road.

So, if the car in front of you slows down, you'll need to step in and adjust your speed manually. This trusty system comes standard on most cars and is great for saving some fuel on those long road trips .

Adaptive Cruise Control (ACC)

Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance .

It's like having an extra set of eyes on the road, making highway driving a breeze. Plus, some ACC systems can even handle stop-and-go traffic, bringing your car to a full stop and then picking up speed again when traffic gets moving.

Predictive Cruise Control

Predictive Cruise Control is like the fortune teller of cruise control systems. It uses GPS and map data to see into the future and predict what's coming up on the road, like hills or curves, and adjusts your speed accordingly. This means you get a smoother ride and better fuel efficiency, but it all depends on the quality of the GPS and map data. If that's a bit out of date, your fortune-telling cruise control might not be so accurate. It's usually found in more high-end vehicles where top-notch fuel efficiency is a focus for the engineers.

Cooperative Adaptive Cruise Control (CACC)

And then we have Cooperative Adaptive Cruise Control, or CACC. This is like the team player of cruise control systems. It allows cars to talk to each other, coordinating their speeds to maintain a safe distance. It's like having a well-coordinated team of cars all working together to make the traffic flow smoother and reduce congestion. Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. This tech is still pretty new, but it's got a lot of potential. Imagine a future where traffic jams could be a thing of the past.

Remember, these systems are here to make your drive smoother and safer, but they're not a replacement for your attention. No matter how fancy your cruise control is, these systems can be greatly influenced by external conditions like weather and traffic, and they should always be used as aids, not replacements, for attentive driving.

Common Cruise Control Symbols and Indicators

Understanding the various symbols and indicators associated with cruise control is important for safe and effective usage. These symbols typically appear on the dashboard (or on the side of the steering wheel) and may include a speedometer icon, "SET," "RES" (resume), and "CANCEL". Be sure to consult your vehicle's owner's manual for specific details and explanations of these symbols.

Benefits of Using Cruise Control

Cruise control offers several benefits to drivers, especially during long road trips or highway driving.

Fuel Efficiency

One of the main advantages of using cruise control is improved fuel efficiency. By maintaining a constant speed, cruise control helps reduce fuel consumption, leading to better gas mileage. Rapid acceleration and deceleration, on the other hand, can lead to increased fuel consumption.

Comfort and Convenience

Cruise control allows drivers to take their foot off the accelerator pedal, reducing fatigue and improving comfort during long drives. It also helps drivers avoid unintentionally exceeding the speed limit by setting a maximum speed.

When used correctly, cruise control can contribute to safer driving. By maintaining a steady speed, it reduces the likelihood of erratic driving behavior and potential accidents. However, it is important to note that cruise control shouldn't be used in certain conditions, such as heavy traffic or slippery roads .

Troubleshooting Common Cruise Control Issues

Occasionally, you may encounter issues with your cruise control systems. Common problems include cruise control not engaging or disengaging unexpectedly. Possible causes may include a faulty brake light switch, malfunctioning sensors, or issues with the control module. If you experience any problems with your cruise control, it's best to have a qualified technician diagnose and repair the issue for you.

Cruise Control and Road Etiquette

Practicing proper road etiquette while using cruise control is essential for a safe and pleasant driving experience. Here are some tips on how to use cruise control courteously:

• Avoid using cruise control in heavy or congested traffic, as it may hinder your ability to react quickly to changing conditions.
• Be mindful of other drivers when setting your speed. Avoid setting a speed that's significantly slower or faster than the flow of traffic.
• If you are in the passing lane and using cruise control, be sure to adjust your speed or temporarily disengage the system to allow faster-moving vehicles to pass.
• Always signal your intentions, such as lane changes or exiting the highway, even when using cruise control.

The Future of Cruise Control Technology

Cruise control technology plays a vital role in the development of autonomous vehicles, or self-driving cars . In autonomous vehicles, cruise control systems work together with other advanced driver assistance systems (ADAS) to enable the vehicle to operate without direct driver input. These systems include lane-keeping assist, automatic emergency braking, and collision avoidance systems.

As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. For example, some autonomous vehicles are equipped with advanced cruise control systems that can navigate complex traffic scenarios, merge onto highways, and even change lanes autonomously.

While fully autonomous vehicles are still in the developmental stages, the integration of cruise control technology is a big step toward creating safer and more efficient transportation systems.

As automotive tech continues to advance, cruise control systems are becoming more intelligent and capable. Here are some potential developments we can expect to see in the future of cruise control technology:

• Integration of artificial intelligence (AI) to improve decision-making and responsiveness in adaptive cruise control systems.
• Enhanced connectivity and vehicle-to-vehicle (V2V) communication, enabling cars to share information about traffic conditions and coordinate their speeds for smoother traffic flow.
• Greater customization and personalization options, allowing drivers to set preferences for cruise control behavior, such as following distance and speed adjustments.

Overall, the future of cruise control technology holds promise for creating a more seamless and enjoyable driving experience, with a focus on safety, comfort, and sustainability.

Debunking Myths About Cruise Control

Let's address and debunk some common misconceptions about cruise control:

Myth : Cruise control can be used as a substitute for driver attention.

Fact : Cruise control is a driver assistance feature, not a replacement for attentive driving. Drivers should always remain alert and ready to take control when necessary.

Myth : Cruise control increases the risk of accidents.

Fact : When used appropriately, cruise control can contribute to safer driving by maintaining a steady speed and reducing erratic driving behavior.

Cruise Control Explained: How It Works, And When You Should Use It

Self-driving cars are becoming increasingly intelligent , but whether they'll ever be ubiquitous and fully capable remains unclear. Tesla notes (for now) that its Full Self Driving Capability is "intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any moment." For many drivers at present, the automatic functions of their cars are limited to the likes of beeping sensors, flashing displays, and features like cruise control.

Cruise control is a feature provided as standard on a wide range of vehicles; it's one of those functions that some drivers adore and others barely use. While the feature doesn't take over from the driver by any means, it can significantly ease their burden. Essentially, cruise control allows drivers to select an appropriate speed for the road, conditions, and general journey they're currently on, and automatically prevents the vehicle from deviating from that speed.

Experienced drivers, of course, will probably be familiar with the basics of what cruise control does, even if they haven't really used it themselves. Rather more complex than that, though, is the question of exactly how it keeps the vehicle moving at a specific speed. If you've ever wondered how cruise control works, what the pros and cons of using it are, how it's developed since its introduction, and/or when to use it, this is just the piece for you.

The essentials of how cruise control works

Cruise control as we know it today has its roots in the ingenuity of Ralph Teetor. Though he lost his vision following an accident, Teetor rose to become the president of the Society of Automotive Engineers. In that capacity, he used both his passion for auto safety and his extensive experience with other drivers to create the first example of cruise control. In 1950, Teetor held a patent for technology referred to as a "Speed Control Device For Resisting Operation Of The Accelerator," also called the Speedostat, and it worked just as the name implied: the driver could opt for a certain speed by selecting it from the dash, then, through the drive shaft, a piston would provide resisting force on the pedal after arriving at that speed.

The basics of how cruise control functions haven't actually changed very much. Depending on the vehicle model, the input for choosing the desired speed may now be a touchscreen, but the effect is the same: a connected actuator receives the signal from the control device, and, as it runs to the valve for the throttle, is used to control the strength of the force acting on the throttle. Accelerating faster or slower depending on how much faster the inputted speed is, the vehicle will then reach said speed and hold the accelerator in place (though not necessarily physically as Teetor's Speedostat did). This is a mechanically-oriented form of cruise control, but some modern vehicles utilize adaptive cruise control instead.

How is adaptive cruise control different?

The basic concept of cruise control, of course, is centered more around what the specific vehicle is doing, rather than what's on the road around it. Drivers can simply brake as they typically would in response to other drivers, overriding the constant-speed effect of cruise control, which means that autonomy isn't really a factor in cruise control beyond maintaining the speed. Adaptive cruise control like the kind found in some Acura vehicles , however, is a little more sophisticated.

Adaptive cruise control is a feature more able to do exactly that: adapt. This means that while the driver selects the vehicle's cruising speed as before, it is not locked to that speed. Another crucial thing to take into account is the vehicle's distance from others; adaptive or autonomous cruise control adds small and discreet radar systems (inputs situated somewhere near the vehicle's front lights) to the equation to monitor the surrounding area. These radars have ranges from approximately 100 feet to around 600 feet, depending on the vehicle.

A car with ACC will commonly boast small wheel-mounted units that measure its speed, along with a front-mounted one that can determine how far away other vehicles are. The former can adjust how fast your vehicle is moving relative to any motorists ahead, thereby ensuring that you always maintain your selected distance from them. Braking capacity while the system is active differs, but typically, the driver will be alerted to brake heavily if necessary (if a driver ahead does the same for instance).

When cruise control should be used

Some drivers often have the luxury of wide, peaceful, near-empty roads. For others, driving tends to be a commuter's cacophony of traffic jams, honking horns, and slow stop-start-stop-start progress. The experience can differ greatly depending on the time of day and whether it's a weekday or the weekend. The bottom line, though, is that one of these scenarios is a far better fit for cruise control than the other.

Brakes remain operational during the use of cruise control, and engaging them will override the system. This means two things: the driver's attention must still firmly remain on the road as ever (we're not at  level 5 on the autonomous driving scale here) and cruise control has sharply decreased utility in congested areas. By contrast, if you're a driver who frequently takes long-distance trips on open roads, cruise control could be the perfect feature for you. An alert and rested driver is a safe driver, and where longer journeys can compromise those things, cruise control reduces some of that pressure.

Adaptive cruise control, which monitors the ever-changing road ahead continuously via radar or laser, is potentially better equipped to handle congested roads. There's no definitive answer on whether that's the case, however, because this feature is very different from vehicle to vehicle.

Different manufacturers have different cruise control features

Cruise control is a common feature, and adaptive cruise control is becoming increasingly widespread too. The matter of how the two types of cruise control work is a very complex one beyond the basics, though, because different vehicle manufacturers have developed their own unique features for it and implemented the system in different ways.

For example, Audi's Traffic Jam Assist technology can be activated in tandem with its adaptive cruise control, thereby supporting the driver in conditions that aren't optimal for the latter. By means of ultrasonic sensors, radar, and a windshield camera, the vehicle will maintain a consistent distance from the one ahead in traffic while staying oriented on the road. The driver takes full manual controlwhen the congestion clears or Traffic Jam Assist otherwise becomes unsuitable for the situation.

Similarly, select Ford models are among those that offer Intelligent Adaptive Cruise Control, implementing advanced features such as Speed Sign Recognition (which aims to prevent adaptive cruise control users from being caught out by speed limits by adjusting the chosen speed to match them) and Stop-and-Go (limited capacity to stop entirely in response to a vehicle ahead doing the same). As always, drivers should consult their vehicle manual to determine which cruise control features are available and how to use them.

Pros and cons of cruise control and adaptive cruise control

Cruise control can be advantageous for drivers in other ways too. In its capacity to ensure a vehicle remains at a steady speed, where possible, it can boost driving efficiency. According to Natural Resources Canada , varying your speed by around 6 mph every 18 seconds can be 20% more costly in terms of fuel. Cruise control, in a general sense, aims to be as efficient as possible within the parameters the driver provides, which can potentially translate to less fuel being used over time.

This is only the case when driving for longer stretches on wide, clear roads, however. The reason is that there are certain things human drivers are better at than their machine counterparts, and adjusting speed subtly in response to changes in elevation is one of them. Failing to do so can be wasteful. 

On a similar note, Vanderbilt University  found that drivers are more adaptable in their thinking and processing of multiple vehicles and their movements on the road, while cruise control features tend to have a rather narrower focus in terms of the vehicle(s) in front. Cruise control can serve as an invaluable tool for drivers, but isn't infallible. Ensuring that you use it for its intended purpose is the key to best taking advantage of it.

How Does Cruise Control Work?

Cruise control is awesome, be it regular or adaptive cruise. But, how does cruise control work, and can you trust it while driving?

We invented cars as means of transportation, to go faster and to go further. But the evolution of cars didn't stop there. Comfort has become a necessity, leading to the invention of features purely for driver convenience—features such as cruise control.

Cruise control lets you take your foot off the gas pedal without your car losing speed. With cruise control, you enter the speed, and then the car keeps cruising at that speed.

It's bliss for driving long distances on highways, but how does cruise control actually work?

What Is Cruise Control?

Cruise control is a driving assist that maintains a constant driving speed without your foot on the gas pedal. Cruise control has been around for a long time, but only in the past few years has it become more common in economy cars.

There are various types of cruise control mechanisms, and these usually work according to the type of throttle system in your car. However, some manufacturers take this feature to the next level with adaptive cruise control, automatically altering cruise speed.

Cruise control has evolved many times since it was first used in automobiles. As mentioned before, cruise control's working mechanism revolves around the throttle system. Right now, there are mostly two types of throttle systems in the cars you see out in the streets: the older cable throttle and the newer drive-by-wire throttle.

Cruise Control in Older Cars with Cable Throttle

Cable throttle systems use mechanical connections, and thus, the cruise control on these cars works mechanically as well.

In cars with cable throttle systems, the cruise control actuator is connected to the throttle body through a cable on one side. On the other side, the actuator is connected to a pump.

Most cruise control actuators in cable throttle bodies use a set of springs and rely on vacuum pressure. The pump connected to the actuator creates a vacuum that tightens the springs in the actuator and this, in turn, puts tension on the cable. This cable is connected to the throttle body, and when the actuator puts tension on the cable, the throttle body opens in response. This ultimately gives your car gas without the gas pedal being used.

Now remains the question of how a specific speed is set for the actuator. This all goes through the car's electronic control unit or ECU. You press a button in your car to activate cruise control, and the ECU powers the pump in just the right amount to put the right tension on the cable. Lo and behold your car drives without your foot on the gas pedal!

The ECU also takes info from the speed sensor to see if the current speed and the target speed match. If your car is going faster than it should, then the ECU will release some tension on the cable, and if it's going slower, it will increase the tension.

Some cars use valves instead of pumps to create the vacuum in the cruise control actuator. In that case, the ECU is responsible for opening and closing that valve.

Keep in mind that there are various types of cruise control actuators, and not all use springs, though most do.

Cruise Control in Newer Cars with Drive-By-Wire Throttle

The cruise control system in newer cars with drive-by-wire throttle bodies is entirely electronic. Since there are no mechanical parts involved, the ECU gets the current speed and decreases or increases it to reach the target speed.

In these cars, the ECU talks directly to the electronic control module (ECM). The ECM is responsible for controlling the throttle body to accelerate or decelerate. Once you set your preferred speed, the ECU grabs that and sorts it out with the ECM and just like that, your car drives at your preferred speed.

How Does Adaptive Cruise Control Work?

Adaptive cruise control (ACC) is an advanced form of cruise control that takes in information from sensors other than the speed sensor to determine the ideal speed in real-time.

ACC talks to proximity sensors such as radar and lidar, speed sensors, and a combination of cameras to take in the other vehicles on the road and the road itself. Once the signals are received and processed, ACC determines the safe distance and speed.

This system then alters the speed accordingly, reducing your car's speed if you're getting too close to another car in front or if you're nearing a turn. Once the road is clear, ACC accelerates the car to the target speed you have set.

In some cars, ACC can even trigger the brake systems to decelerate the car quickly in case the car in front suddenly brakes or a hazard appears.

Related: How Does Adaptive High Beam Assistance Work?

Cruise Control in Motorcycles

Unlike cars, motorcycles don't have gas pedals. They have gas handles instead. Unfortunately, holding a gas handle for a long duration is much more frustrating than holding a gas pedal. This nuisance has called for a technology similar to cruise control in function but different in design: throttle lock.

Throttle lock functions similarly to cruise control in cable throttle cars, except it skips the actuator and the ECU and directly deals with the throttle body.

Throttle lock works by locking the throttle cable and maintaining a constant amount of tension on the cable. This keeps the motorcycle cruising at a steady speed.

The simplicity of the throttle lock has a catch. Throttle lock doesn't check in with the speed sensors to see if it's going any faster or slower than the target speed, so it only works well on flat roads.

When to Use (and Not to Use!) Cruise Control

Use cruise control on straight roads with little traffic. As a safety measure, braking will disengage cruise control, and on a road with lots of vehicles, you'll need to brake often.

Cars naturally decelerate when you take your foot off the gas pedal, but that won't be the case when you have cruise control activated. It might be too late by the time you hit the brakes when you use cruise control on a crowded road.

This also goes for roads with lots of turns and twists. Entering a sharp turn with high speed is often dangerous. Put the turns behind you and once you have a straight road, engage the cruise control.

Though the point of cruise control is to make your ride more comfortable, it's prone to make you a bit too comfortable. Falling asleep behind the wheels with cruise control engaged is likelier to happen. Albeit this time, the car won't decelerate and will keep going.

Related: Standalone vs. Integrated Car Navigation Systems: What's the Best Option?

Adaptive cruise control solves most of the limitations that come with ordinary cruise control systems, but it still isn't flawless. Adaptive cruise control relies on your car's sensors to decide the appropriate speed, and these sensors can get blocked in bad weather. Snow, mud, rain, and other natural hazards can get in the way of your car's sensors and make the adaptive cruise control less reliable.

Adaptive cruise control has limited access to the braking system, and it won't be able to stop a head-on collision. Use the brakes yourself and remember that cruise control is only a driver assist feature, not an autopiloting system.

With this in mind, please take full control of your vehicle in bad weather and tricky roads. Don't trust the cruise control, be it normal or adaptive.

Cruising with Control

The cruise control system was first strictly found on high-end luxury cars, but now even economy cars are often equipped with this feature. This system makes driving long trips much easier, as you don't have to keep your foot on the gas pedal for hours.

Though cruise control makes things easier, it doesn't mean that you should use cruise control all the time. There are times where you need to take things into your own hands.

​ Troubleshooting Common Issues

System Not Activating

If your cruise control doesn’t activate, start with the basics. Ensure it’s turned on and you’re at the right speed (usually above 25-30 mph). If these aren’t the issues, it might be a blown fuse, a faulty brake pedal switch, or a defective speed sensor. Check your vehicle’s manual for fuse information and consider a professional inspection of the brake pedal switch and speed sensor.

Failing to Maintain Set Speed

Trouble maintaining the set speed often points to sensor issues. Speed sensors inform the cruise control system. If these sensors are dirty or malfunctioning, the system might not maintain the speed. Cleaning sensors and checking for obstructions can help. Also, consider checking wheel alignment and tire condition, as these can affect performance.

Erratic Speed Changes

If your vehicle experiences erratic speed changes with cruise control engaged, this could indicate a problem with the throttle control system or the vehicle’s computer system. These complex issues generally require professional diagnostics and repair.

Adaptive Cruise Control Problems

With adaptive cruise control, problems can arise from blocked sensors or system malfunctions. Ensure that the sensors, often located in the front grille or under the mirrors, are clean and unobstructed. For system malfunctions, professional diagnostics are essential, as these systems involve advanced electronics and software.

​ Comparative Analysis of Modern Cruise Control Systems

In the realm of modern vehicles, cruise control systems have evolved significantly, offering a range of functionalities tailored to enhance driving experience and safety. Here’s a comparative analysis of several popular systems.

Cruise Control Explained – All You Need to Know

Cruise control has come a long way since first invented and patented by Ralph Teetor in 1950, who originally named it the “Speedostat”. Chrysler Corporation was the first manufacturer to offer the groundbreaking mechanism as an option on several of its luxury vehicle models nine years later. Today, cruise control is rapidly becoming the standard on all new vehicles, providing drivers with increased convenience on their daily drive.

As you’re learning how to operate a vehicle , understanding cruise control will help increase your comfort behind the wheel and knowledge of driving.

What is Cruise Control?

Cruise control is an electronic device within your vehicle that controls the speed of your vehicle. It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel.

Different Types of Cruise Control

There are 3 types of cruise control systems.

• Speed Limiter
• Adaptive Cruise Control
• Semi-autonomous Cruise Control

What is a Speed Limiter?

A speed limiter will limit how fast the driver can accelerate behind the wheel. All modern vehicles contain a standard speed limiter capping speed between 120 mph and 180 mph depending to protect the vehicle’s engine and discourage reckless driving. However, an additional limiter can be added as an option in many European-made cars, as well as Tesla, Ford, and Nissan. Drivers are still required to keep their foot on the pedal to keep their vehicle in motion, but will not be able to accelerate past a predefined speed limit.

What is Adaptive Cruise Control?

Adaptive cruise c ontrol uses sensors around the vehicle’s exterior to maintain speed while keeping a safe following distance from the car ahead. The system will slow you down and speed you up as the flow of traffic fluctuates throughout your commute, removing a lot of the stress from daily driving. However, adaptive cruise control may not work well in bad weather or protect you from sudden movements, so you will want to always keep your full attention on the road.

What is Semi-autonomous Cruise Control?

Luxury automakers such as Tesla and Audi are implementing the newest rendition of cruise control on their latest vehicle models – Semi-autonomous Cruise Control. It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver.

How to Use Cruise Control – 6 Step Guide

These are the steps to using cruise control effectively.

• Observe weather conditions
• Build speed
• Engage cruise control
• Set cruise control
• Watch the road and steer
• Brake to disengage

1 – Observe weather conditions

As mentioned, cruise control may become inconsistent in rainy, snowy, or otherwise hazardous conditions. If you must drive in this situation, it may be a better idea to do so manually. Cruise control works best on a clear day with constant traffic flow.

2 – Build speed

Accelerate to your desired speed as you prepare to activate cruise control. US highways have posted speed limits between 55 mph and 75 mph. Do not attempt to set cruise control when you are traveling over the speed limit.

3 – Engage cruise control

Once you’ve reached your desired speed, engage the cruise control. This step will vary widely based on your vehicle make and model, however, many cruise control settings are accessible from the steering wheel controls. Check your owner’s manual for further information.

4 – Set cruise control

After turning on cruise control, you’ll need to set your desired speed. Many systems set the cruise control at the current speed, while others require you to manually set one. You can increase and decrease this speed as needed without interrupting the mechanism.

5 – Watch the road and steer

Watching the road is essential when cruise control is engaged. Cruise control is not a substitute for a human driver and will require supervision at every step. If you are using a semi-autonomous system, you will not need to steer but will need to keep at least one hand on the wheel for safety measures.

6 – Brake to disengage

When cruise control is no longer needed, or you need to quickly make a maneuver, simply apply pressure to the brakes to disengage the system. Once deactivated, you will be in full control of your vehicle once again.

When NOT to Use Cruise Control

While cruise control is a convenient feature for modern drivers, it is not perfect for all circumstances. In fact, utilizing the system can be quite dangerous if you’re not careful. Be sure not to use cruise control under these conditions.

Heavy Traffic

Heavy, or stop-and-go traffic is not ideal for safely using cruise control. When engaging cruise control on the highway, ensure your lane is clear and there are no vehicles stopping ahead.

Wet or Icy Conditions

You need to be driving slowly while on wet and icy roads. While cruise control keeps a constant, predetermined speed, it takes away a lot of the manual control needed to stay safe when it’s raining or snowing.

City Driving

While driving through the city, you’ll face a number of stop lights and stop signs that will require manual braking. This action will automatically disengage cruise control.

Winding Roads

Winding roads require more attention than straight, flat streets. Cruise control systems, even adaptable cruise control, may not always detect these streets correctly, causing accidents.

Fatigued Driving

Driving while fatigued is never a good idea, but even less so while using cruise control. Utilizing the system may add to your fatigue, as you give your vehicle more control of the journey. If you’re even the least bit tired, you should never turn on cruise control.

As you can see, cruise control is a great way to relieve much of the stress that comes with everyday driving. The constant rate of speed can also drastically improve fuel efficiency for longer drivers. Cruise control has had a positive impact on the driving industry for 70 years and shows no signs of disappearing anytime soon.

Your vehicle’s cruise control system unlocks numerous benefits at the touch of a button — but according to web search data, drivers still have plenty of questions about what it is, what it does, and how it works.

What is Cruise Control? A Comprehensive Guide Back to video

Below, we’ll answer some of the most popular Internet search questions about cruise control, so you can make the best use of this important system.

What is Cruise Control?

With cruise control, your vehicle will maintain a steady speed when the system is set.

What is adaptive cruise control?

With adaptive cruise control, the vehicle will also automatically slow down and speed up to maintain a safe position in traffic.

How does cruise control work?

Cruise control work with a manual transmission just the same way it does with an automatic.  Drivers set their cruising speed with a button press, and the system works the throttle automatically to maintain the desired cruising speed as evenly as possible. In some vehicles with a manual transmission, pressing the clutch pedal to shift gears turns the cruise control off, requiring an additional button press to reengage it after a gear change.

In other cars with a manual transmission, pressing the clutch pedal simply pauses the cruise control system a moment, allowing drivers to complete their gearshift. When they’ve released the clutch, the cruise control picks up where it left off — no additional button press required.

Is cruise control more fuel efficient?

Yes.  Increasing your vehicle’s speed uses fuel. While cruising, even a highly competent driver who isn’t using cruise control will tend to slow down and speed up in a repeated cycle, possibly several times per minute. Though fluctuations in speed may be slight, they do cause your engine to use more fuel than required. Point is, the more time you spend at a steady speed, the less fuel your engine needs.

For most drivers, using cruise control on the highway at 80 km/h can reduce fuel consumption by about 20 per cent. For drivers who find difficulty in maintaining a steady speed and frequently experience big fluctuations, using cruise control can cut fuel use by over 40 per cent.

Depending on what you drive and how fast you drive it, using cruise control could save you between $4 and $20 per hour — based on information from Natural Resources Canada that shows most drivers who don’t use cruise control on the highway will tend to experience a 10 km/h speed fluctuation about three times per minute.

Drivers who have the most difficulty managing their cruising speed could be using 60 per cent more fuel than they need to.

Is cruise control bad for your transmission?

No.  Your vehicle’s engine, transmission and other components are designed to work hand-in-hand with its cruise control system and are extensively tested and integrated with one another for trouble-free performance.

Using cruise control also reduces wear and tear on both your engine and transmission by running things more smoothly and steadily, and reducing workload on both components.

Can you add cruise control to a car?

Yes.  Depending on the year, make and model, cruise control may be available for add-on or retrofit. Professional installation is recommended, and you’ll want to talk to a professional about the specific availability of parts and integration for your vehicle.

In many cases with modern cars, it’s generally easier and more cost effective to just opt for a unit equipped with cruise control from the factory. Cruise control is widely available as standard equipment on most modern vehicles.

Can cruise control get stuck?

Yes , but it’s extremely rare. Older cable-based cruise control systems seem more prone to this rare problem, in which the cable can slip or bind, making the throttle stick into position. More modern vehicles with electronic throttle and monitoring systems make this problem even less likely.

If the cruise control on your car fails to disengage when you want to slow down, slip the vehicle into neutral to disconnect drive power from the wheels, pull over, and address the situation.

However, chances are, you’ll never experience this problem.

When should cruise control be used?

Any time you’re trying to drive at a constant speed.  Whether around town at 60 km/h, in a residential area at 40 km/h, or out on the highway at 105 km/h, switching the cruise control on makes for a smoother and more fuel efficient drive that’s easier on your engine and transmission. it can also help you do your part to maintain the steady and efficient flow of traffic.

Most cruise control systems can be engaged at speeds above 30 km/h.

When should cruise control not be used?

Any time you can’t safely drive at a steady speed.  If the road surface is snowy, icy, slushy or very wet, you’ll want to think twice about switching your cruise control on.

In older cars, having your cruise control engaged on a wet or icy road could allow the vehicle to accelerate or experience wheelspin when driven wheels encounter a low-traction surface. Here, the cruise control system maintains throttle pressure, even in situations where it should be released instead. This could lead to a loss of control.

In more modern vehicles, electronic monitoring is used to automatically disengage cruise control when one of the following happens:

• one or more wheels slip
• one or more wheels leave the surface of the road after a major bump or dip

Use your judgement. Safely navigating certain slippery or dangerous driving conditions requires careful manual control of your vehicle’s throttle, and in these situations, you’re best to leave the cruise control off.

What causes cruise control to kick off?

If the cruise control in your vehicle suddenly kicks off, a few things may be to blame.

Sometimes, cruise control disengages automatically when the vehicle’s automatic wipers detect heavy rainfall, or when a wheel spins or (briefly) leaves the surface of the road after a big bump or dip. In other situations, there may be a problem with one or more sensors or switches, including the brake pedal switch, throttle position sensor, or one or more wheel speed sensors.

Your modern cruise control system relies on various sensors and switches to do its job properly. As a failsafe, any problem with these sensors can cause the cruise control system to go offline. If you notice this happening regularly, have your vehicle diagnosed by a professional.

Will the cruise control work with an ABS light on?

Probably not.  Your car’s Antilock Braking System works hand-in-hand with your cruise control system, and any fault with the ABS system will typically take your cruise control offline until it’s fixed.

An ABS warning light in your instrument cluster can indicate one of several major problems or malfunctions, so be sure to have a professional investigate as quickly as possible.

Will cruise control apply the brakes?

No, but adaptive cruise control will.  Standard cruise control (simply called cruise control) holds your vehicle’s speed as constant as possible once set. More advanced adaptive cruise control systems use camera or radar-based sensing to determine the traffic situation in front of your vehicle, and can automatically apply the brakes to maintain a pre-set following distance.

With cruise control, drivers need to brake to slow down as they close in on a slower vehicle in traffic. With adaptive cruise control, the system makes these braking inputs automatically, and the vehicle speeds back up to its pre-set cruising speed once traffic clears.

Before you buy, be sure to determine which type of cruise control system is fitted to the car you’re considering.

What is Super Cruise?

Super Cruise is a next-level driver assistance feature available on certain GM vehicles.

With Super Cruise, the vehicle uses special GPS hardware and sensors to accurately compare its position to a 3D map of pre-qualified highways .

On these pre-qualified highways, Super Cruise allows drivers to go hands-free for extended periods as the vehicle automatically maintains its cruising speed, adjusts that speed for changing traffic conditions, and even precisely follows the curves in the road. It can even make hands-free lane changes.

Super Cruise is not an autonomous system, and in order for it to work, drivers need to keep their eyes on the road — there’s even a camera that monitors the position of the driver’s eyes to make sure they’re focused on the road ahead.

What Is Adaptive Cruise Control?

Adaptive cruise control (ACC) is a system designed to help road vehicles maintain a safe following distance and stay within the speed limit. This system adjusts a car's speed automatically so drivers don't have to.

Adaptive cruise control (ACC) is a system designed to help vehicles maintain a safe following distance and stay within the speed limit. This system adjusts a car's speed automatically so drivers don't have to.

Adaptive cruise control is one of 20 terms used to describe its functions so that you might see adaptive cruise control as the following in advertisements and vehicle descriptions:

• Active cruise control
• Dynamic cruise control
• Radar cruise control
• Automatic cruise control
• Intelligent cruise control

ACC functions by sensory technology installed within vehicles such as cameras, lasers, and radar equipment, which creates an idea of how close one car is to another, or other objects on the roadway. For this reason, ACC is the basis for future car intelligence.

These sensory technologies allow the car to detect and warn the driver about potential forward collisions. When this happens, red lights begin to flash, and the phrase 'brake now!' appears on the dashboard to help the driver slow down. There might also be an audible warning.

Advantages of Adaptive Cruise Control

Limitations of adaptive cruise control.

Although there are many advantages to adaptive cruise control, there are still limitations to consider. One of the main faults in this system is the fact that it is not entirely autonomous. The driver of the vehicle still needs to practice safe driving habits that will work in tandem with this technology to produce the best results. Similarly, adverse weather conditions like snow, rain, or fog might confuse the system's sensors, as well as environmental factors such as driving through tunnels.

What Is the Difference Between a Level 1 Autonomous Car and a Level 2 Autonomous Car?

According to SAE International, when a car only has autonomous cruise control , it is considered to be a level 1 autonomous car. In contrast, a vehicle with autonomous cruise control and an additional feature, such as lane control, gets classified as a level 2 autonomous car.

How Much Does an Adaptive Cruise Control System Cost?

According to ExtremeTech, The cost of an adaptive cruise control system will vary depending on how many features you want. If you're going to have an ACC with all available features, you should be willing to pay anywhere between $2000 and $2500. If you are looking for minimal cruise control that would benefit speeds of up to 20-25 miles per hour, these more basic ACCs can cost as low as $500. The good news is that as ACC becomes more common, it will most likely reduce in price.

History of Adaptive Cruise Control

U.S. News says Mitsubishi first introduced adaptive cruise control in Japan in 1992 . This was a lidar-based distance detection system that detected objects that were getting too close. It was labeled as 'Debonair' and it was programmed to provide a warning to the driver about oncoming objects. The main difference was that it was the driver's job to apply the brakes and reduce their speed.

However, two years later in 1995, the Mitsubishi Diamante featured an upgraded approach to the Debonair called 'Preview Distance Control.' Unlike the original technology, this laser-powered system could adjust a driver's speed by downshifting or controlling the throttle. The driver was still responsible for applying the brakes.

From the early 2000s onward, big names in the car industry, such as Ford, BMW, Mercedes, Cadillac, Volkswagen, Infinity, Hyundai, Toyota, and Audi, created their versions of adaptive cruise control in their vehicles. These individual features have evolved into a high-tech system with automatic braking and speed control.

Types of Adaptive Cruise Control

Radar-based systems.

According to eInfoChips, radar-based systems work by placing radar-based sensors on or around plastic fascias to detect your vehicle's surroundings. Each radar sensor works together to create a comprehensive picture of the vehicle's proximity to other cars or potentially hazardous objects. This type of sensor can look different depending on the design and model of the car.

Laser-Based Systems

As mentioned by Electronic Design , this type of ACC system operates out of a large black box typically placed in the grille of your vehicle. It uses laser technology to detect the proximity of objects to your car. It does not operate well during rainstorms and other weather conditions.

Binocular Computer Vision Systems (Optical)

According to ExtremeTech, this is a relatively new ACC system put into use in 2013. It uses small cameras that are placed on the back of a vehicle's rearview mirror to detect front-facing objects.

Assisting Systems

Assisting systems are radar-based add-ons that customers can buy together. These pre-crash systems can offer lane control, brake assistance, cruise control, proximity alerts to objects like corners, and steering power.

Multi-Sensor Systems

According to Fierce Electronics , adaptive cruise control systems sometimes integrate more than one type of sensor to aid in a vehicle's operation. Multi-sensor systems incorporate several different sensor types to provide a driver with advanced information. These sensors might include GPS data equipment or cameras to gather information about a vehicle's geographic environment and proximity to other cars.

Predictive Systems

As mentioned by Autoblog, prediction systems are a type of ACC that uses sensory data to predict the actions of neighboring vehicles. This means that your car might slow down to brace for another vehicle suddenly switching lanes and, in doing so, promotes passenger safety.

Adaptive cruise control is evolving each year. Car companies are continuously making adjustments to this technology and, in doing so, creating more common and affordable options that can be purchased with a new car or added to older car models, making driving safer for everyday people.

Advanced Driver-Assist Systems Make Our Lives Easier (and Safer)

Sadly, millions of people are involved in car crashes every year. According to the CDC, about 90 people die each day in the U.S. as a result of a car crash. However, crash fatalities are decreasing almost every year, even though there are more cars on the road. While the reasons for the decline aren’t clear-cut, advances in overall vehicle safety and advanced driver-assist systems seem to be contributing to the decline.

While most of today’s cars offer multiple driver-assist features, cruise control is still arguably one of the greatest advancements in the history of car technology. Interestingly, the feature was first invented over 60 years ago. Since then, there have been notable improvements that make the latest versions of cruise control safer and much more useful. 

The invention of cruise control, along with its evolution to adaptive cruise control, marked the beginning of what may eventually lead to self-driving cars. Continue reading to learn all about adaptive cruise control.

The History of Cruise Control

Various forms of cruise control were used in cars dating all the way back to the beginning of the twentieth century. However, modern cruise control was invented by American engineer Ralph Teetor in 1948. He secured a patent for the technology in 1950, and it made its way into passenger cars by the 1960s.

Teeter came up with the idea while riding along in a car with his lawyer. As a passenger in the car, he noticed that every time his lawyer talked, the car changed speeds.

Adaptive cruise control’s roots date back to 1992 when Mitsubishi launched a Lidar-based distance-detection system in Japan. However, the technology didn’t adjust the car’s speed on its own, but rather alerted the driver to take action. 

By 1995, Mitsubishi improved the system to adjust the car’s speed on its own via transmission and throttle management, though actual braking was still controlled by the driver. In the early 2000s, many automakers started offering their own, more advanced versions of adaptive cruise control.

What Is Cruise Control?

To most people, this may seem like a silly question. However, to better understand the evolution of cruise control, it’s important to take a look at its basic functionality.

Cruise control is a system designed to automatically control a vehicle’s speed, which the driver must pre-set after activating. It’s most useful for long highway or freeway drives, and/or in areas where there’s not much traffic, or a need to stop often. Cruise control isn’t very useful at low speeds, or in areas where there are many stop signs or traffic lights.

With cruise control engaged, you don’t have to keep your foot on the accelerator pedal or work to maintain a consistent speed. This means you can more easily adjust your seating position, rest your legs and feet, and focus on other aspects of driving. As an aside, keeping a car at a consistent speed typically leads to better fuel economy.

The controls and buttons for cruise control vary among vehicles. Typically, they’re found on either the steering wheel or a stalk on the steering column. The driver holds a steady speed using the accelerator pedal and then “sets” the speed before taking their foot off the pedal. There are also “+” and “-” buttons to change speed incrementally, as well as a button to disengage the feature and/or resume the pre-set speed. Touching the brake pedal immediately turns off cruise control.

Adaptive cruise control (ACC) is a system that helps cars stay within the speed limit or the pre-set speed while maintaining a safe, predetermined distance behind a “leading” car. When the vehicle in front of you speeds up or slows down, the system adjusts the car’s speed as necessary. 

Some advanced adaptive cruise control systems have “stop-and-go” technology – sometimes called traffic jam assist. This means the system will, when necessary, bring the car to a complete stop, wait for traffic to clear or for the leading car to begin moving, and then accelerate again to the speed limit or pre-set speed. The system continues to maintain a safe distance throughout these maneuvers.

While adaptive cruise control is the most commonly used term for this technology, different automakers have different names for it. If you read that a car offers smart cruise control, active cruise control, automatic cruise control, dynamic cruise control, radar cruise control, or intelligent cruise control, be sure to find out exactly what the feature’s capabilities are.

Most importantly, find out if the feature adjusts the car’s speed on its own, and if it has stop-and-go capability. Be sure to test-drive any vehicle before buying or leasing it. Get acquainted with the adaptive cruise control feature during your test drive. Make sure you understand exactly how it works and what it’s capable of before moving forward with the transaction.

How Does Adaptive Cruise Control Work?

Various car manufacturers have different technologies for adaptive cruise control. However, the basic idea is the same. The car uses either a laser or radar to measure the distance to the leading vehicle. These are essentially the same lasers and radars used for features like forward collision warning and automatic emergency braking. They’re also used in vehicles with semi-autonomous technology. For this reason, it’s fair to say that cruise control was the first step toward what may eventually evolve into self-driving vehicle technology.

It’s important to note that some laser-based adaptive cruise control systems won’t function properly in inclement weather and/or if the sensors are wet or dirty. Radar-based systems are largely unaffected by weather or debris. While more systems employ radar than lasers, be sure to find out which technology your car – or the car you’re planning on buying – uses.

Adaptive cruise control isn’t often a standalone technology. Instead, it’s usually part of a suite of safety systems that work together. If a car has adaptive cruise control, it likely also has forward collision warning and automatic emergency braking. Some more advanced vehicles also have pedestrian detection, as well as systems that help keep your car in its lane, or even help steer the car on the highway when adaptive cruise control is engaged.

What Are the Limitations of Adaptive Cruise Control?

Like almost all vehicle safety technologies, adaptive cruise control is constantly improving. However, it’s still not a substitute for a human driver. While adaptive cruise control is meant to reduce stress and make driving easier, you still need to remain aware, engaged, and ready to take over the accelerator and brake pedal at a moment’s notice.

Adaptive cruise control isn’t meant to steer the car, though other complementary safety systems may help with steering as well. Adaptive cruise control systems with stop-and-go technology will monitor the car in front of you and adjust the speed accordingly. Some systems even observe speed limit signs and slow down around tight curves. With that said, if another driver slams on the brakes in front of you, cuts you off, or makes a sudden maneuver, you should immediately take over. Remember, some cruise control systems either won’t operate or shouldn’t be used in inclement weather.

While your car may also have features like automatic emergency braking, you can’t count on those features to do the job for you. Instead, the features are there just in case you don’t react quickly enough.

Should You Avoid Cars That Don’t Have Adaptive Cruise Control?

When searching for a new or used car, you should try to prioritize finding a vehicle with as many of the latest advanced driver-assist systems as possible. This is especially true if you plan to keep the car for many years. 

Safety is of the utmost importance when shopping for a car. As vehicle safety systems are improving rapidly, it doesn’t take long for a car’s safety systems to become dated or even considered obsolete. For this reason, making sure you have the latest advanced driver-assist systems means you’ll be able to keep your car for a longer period of time before its features are no longer consistent with the most up-to-date technologies.

Is Adaptive Cruise Control Worth it?

It depends. While any technology that will make your life easier and safer is arguably worth it, adaptive cruise control can be a pricey option in some cars. You may have to buy a trim above the base and/or add a package. However, in many cars, adaptive cruise control comes standard, usually as part of a full suite of active safety technologies.

When you’re shopping for a car, make sure it comes equipped with as many safety systems as possible. If you have your eyes on a vehicle, and you learn that it doesn’t include a suite of safety systems, find out how much it costs to add them. If it exceeds your budget, you may want to consider a competing model that includes adaptive cruise control and other safety systems as standard.

Which Cars Have Adaptive Cruise Control?

Nearly every automaker offers adaptive cruise control. However, some systems are more advanced than others. Automakers such as Audi, BMW, Ford, Honda, Hyundai, Kia, Nissan, and Toyota are generally known for having some of the best advanced driver-assist systems, though many other brands offer adaptive cruise control technology that works well.

While advanced driver-assist systems like adaptive cruise control were once reserved for luxury cars or top-level trims on larger cars and SUVs, that’s not the case today. In fact, well-priced small cars like the Honda Civic , Mazda3 , Subaru Legacy , and Toyota Corolla come standard with adaptive cruise control. Even budget-mobiles, such as the Honda Fit and Nissan Versa offer the feature.

Many of today’s SUVs come standard with adaptive cruise control as well, and those that don’t have it on the base model still offer it as an upgrade. The feature even comes standard on some small, relatively inexpensive SUVs, including the Honda CR-V , Mazda CX-3 and CX-30 , Subaru Forester , and Toyota C-HR .

What is cruise control in a car? Meaning and how does it work?

Cruising on the highway can be a lot of fun. However, it demands maintaining a constant speed for a long time. To achieve that, you need to press the accelerator pedal continuously, which can get tiring after a while. That’s when the cruise control feature of your car comes into play. So, what exactly does it do and how does it work? This article explains cruise control in a car and how to use it in different driving conditions. So, without stepping on the ‘brake’ pedal, read on!

What is cruise control in a car?

It is a system that accurately maintains the speed set by the driver without any external intervention. It automatically controls the speed of a car and only allows the vehicle to hit a speed set by the driver. It does not allow the car to cross that speed limit. This feature has become common among modern cars. You can even find this feature in the top-spec variants of some of the affordable hatchbacks and sedans.

How does the cruise control system work?

Cruise control in a car replicates the inputs of a driver to control the vehicle’s speed. But instead of pressing the accelerator pedal, it uses a different mechanism to maintain a constant cruising speed.

Initially, the system used a cable to control the accelerator (throttle valve). You can find these mechanisms in older cars. It adjusted the vehicle's speed by engaging the throttle with the help of an actuator that is controlled by a cable. The throttle valve is responsible for the power and speed generated by the engine. So, depending on the speed set by the driver, the system automatically adjusted the throttle position.

But with the advent of technology in the automotive industry, the cruise control system in modern cars entirely relies on electronics. Instead of a cable, the system now communicates with the throttle via various sensors connected to a computer (ECU - Electronic Control Unit). So, when you set a speed, the ECU calculates the throttle position and engages the throttle wirelessly.

The system constantly maintains the speed set by you (driver) irrespective of road conditions. For example, if there’s an incline ahead, cruise control adjusts the throttle accordingly to maintain the same speed.

How to use cruise control?

Before engaging the cruise control in a car, remember that the system is not intended to be used in adverse weather conditions. For example, you may refrain from driving the car at cruising speeds when it’s raining heavily. The low visibility and unpredictable road conditions make it unsafe to drive at such speeds. So, always be mindful of the weather condition and your surroundings before engaging the system.

Here are the steps to use cruise control.

Step 1 - Before activating cruise control, build up speed by accelerating the car. However, do not cross the speed limit of that particular road/highway.

Step 2 - Once your car reaches the desired speed, activate cruise control. Generally, the system activation button will be on the steering wheel. However, locating the exact button when the vehicle is parked is better to avoid any distractions while driving.

Step 3 - Next, you can take your foot off the accelerator pedal. If you have set the cruise control correctly, the car should maintain the cruising speed.

Step 4 - Keep your eyes on the road as it is very easy to get distracted when the car is accelerating automatically.

Step 5 - If you wish to accelerate when the cruise control is engaged, you can press the ‘+’ button on the steering wheel to briefly engage the accelerator pedal.

Step 6 - To decelerate, press the ‘-’ button on the steering wheel. You can also tap on the brake pedal. However, as a safety precaution, almost all cars will deactivate the cruise control as soon as you press the brake pedal.

The buttons to activate cruise control or accelerate/decelerate may vary from one car to another. So, do check the owner’s manual before fiddling around with the system. It’s better if you are familiar with the controls before driving the vehicle, as it will avoid unnecessary distractions.

How to install cruise control in a car?

Can you install cruise control in a car? The answer is both yes and no. You may install an aftermarket kit if it’s an old car that does not rely on electronics to control all the engine-related functions. But installing such a kit becomes almost impossible in modern cars due to the complex electronics.

It is a complex process to install the system in new cars as you have to fiddle with electronics, and it also requires the fitment of hardware. So, it can only be done during the time of car manufacturing. Moreover, if you try installing an aftermarket kit, you may void the warranty offered by the OEM (Original Equipment Manufacturer). On top of that, it is not recommended to go for an aftermarket cruise control kit as it may compromise safety.

Newly launched cars are equipped with cruise control except for a few entry-level models. So, instead of investing in retrofitting a system, it's better and safer to spend that money on buying a car with a built-in system.

Adaptive cruise control

The new technology also allows the system to automatically adjust the car's speed depending on the speed of the vehicle ahead. This feature is known as adaptive cruise control. It ensures that the car maintains a safe distance from the vehicle ahead despite the constant change in speed of the vehicle moving ahead. It is instrumental in highways or during rush hour traffic and reduces driver fatigue.

It is also a level 1 autonomous driving system. The system uses radar sensors to calculate the speed and distance of the car ahead. For instance, if the vehicle in front of you slows down/speeds up, a car with adaptive cruise control will reduce speed/accelerate automatically without any external inputs.

You can find this feature in premium cars. But gradually, it is trickling down to not so expensive cars as well. Adaptive cruise control is a part of an advanced driver assistance system.

Pros and cons of cruise control

Cruise control makes driving easy and convenient, and at the same time, it also takes care of safety. But like every other feature, it has its own set of advantages and disadvantages, which are elaborated in the following section.

Below are some of the pros of the cruise control system.

Reduces driver fatigue: The primary role of cruise control is to maintain a constant speed without you having to step on the accelerator pedal. That means you can rest your right foot and can stay relaxed. It is helpful when you drive long distances on highways where you need to maintain a constant speed for long durations.

Improves fuel economy: When maintaining a constant speed, the engine will not get stressed as it need not change the intensity of operation. To put it in a simple way, when the engine runs at constant RPMs (Revolutions Per Minute) , it consumes less fuel. Hence, when driving long distances on highways, the cruise control system can improve fuel economy.

Helps to drive within the speed limit: You may drive at normal speed on busy urban roads. But when you hit the wide and smooth highways, you may end up crossing the speed limit. You may not even realise that you have crossed the speed limit until you glance at the speedometer. Cruise control can help you in this regard as you can easily set a speed limit and let the system do the work. The system will not allow the car to go over the speed set by you.

Increase/decrease speed with a click of a button: Typically, you use the accelerator and brake pedal to increase/decrease the speed of your car. But when the cruise control is engaged, you can even use the buttons to do the job for you. However, ensure that you are familiar with the functions of the buttons, as it may feel unnatural in the beginning. It is best to practice using the buttons in a safe environment before using them on public roads.

Works well with automatic cars: Cruise control works best with automatic cars as you need not worry about changing gears. The ECU or the onboard computer shifts the gears automatically when there is a change in speed and works well when cruising automatically. It means you only need to focus on steering the vehicle.

As mentioned earlier, cruise control also has some cons, which are listed below.

Limited use on Indian roads: Cruise control is suited for wide and long highways where drivers follow the rules. Although India has some excellent highways, many drivers may disregard rules which creates an unpredictable environment. Also, cattle, dogs and other animals may venture into public roads and make the situation even more tricky. Hence, it may be challenging to cruise at high-speeds.

Hampers reaction time: As mentioned above, the roads in India are unpredictable. You may have to perform emergency braking to avoid any obstacles on the road. When driving with manual controls, your right foot will be on the accelerator pedal, and it is easy to move your foot to step on the brake pedal in an emergency. But, when using cruise control, your right foot will be resting on the floor of the car, and it may take a bit more time to reach the brake pedal. This difference in reaction time may be the difference between you avoiding an obstacle or crashing into it.

Can induce drowsiness: If you use cruise control for long durations, you may end up feeling drowsy. Since the car is accelerating at a constant speed, your alertness level may drop in the long run. Hence, it is recommended that you manually control the vehicle once every 10-15 minutes when using the automatic cruising feature on highways.

Cannot use at night: Cruise control is of no use during night drives as the visibility is poor. Even with well-lit roads, the visibility is not as good as daylight. So, allowing the car to maintain a constant speed may be a safety concern, even on roads that are familiar to you.

It does not work well with manual cars: In a manual car, you have to change gears by yourself. The cruise control will handle the acceleration/deceleration, but you still need to shift the gears manually to maintain the optimum RPM. It can be irritating at times when you need to slow down and accelerate immediately. It may not be a dealbreaker, but it kind of refrains you from experiencing the full potential of the automatic cruising system.

Cruise control vs adaptive cruise control: Key differences

The below table highlights the key differences between cruise control and adaptive cruise control.

What is the difference between cruise control and speed limiter?

Sometimes you may get confused between cruise control and speed limiter as both are related to the car's speed. Refer to the table below to understand the difference between both the systems.

Everything I liked about the larger car was there in the Q3. I drive the model with the larger engine and the power was apparent. This car has the German handling that I wanted, and the fit and finish is excellent. Going a little smaller was not a dealbreaker and I continue to be very satisfied with my new Q3.

2024 Audi Q3 review: Our expert's take

With Audi planning to launch no new vehicles powered by internal combustion engines after 2026, it’s possible that resources are thin for gas-burning vehicles like the Q3, the current generation of which launched in 2019. Accordingly, updates for the small SUV are few.

Related: Here Are 5 Great Affordable Luxury Cars You Can Buy Right Now

In terms of standard equipment, there’s just one update: Adaptive cruise control is now standard across the Q3 line. Other changes are limited to an available wireless phone charger and HomeLink functionality and revised paint options.

Performance Specs

The Q3 continues to offer a turbocharged 2.0-liter four-cylinder engine in two strengths. In the Q3 40, it makes 184 horsepower and 221 pounds-feet of torque. In the 45 S Line, output ratchets up to 228 hp and 258 pounds-feet. Both are paired with an eight-speed automatic transmission and all-wheel drive.

Trim Levels

The 2024 Q3 continues to be available in Premium and Premium Plus trim levels. The base 40 Premium comes fitted with a panoramic moonroof, three-zone climate control, heated front seats, a 10.25-inch digital instrument cluster, an 8.8-inch touchscreen and ambient lighting. Audi’s standard safety suite for the Q3 includes forward collision warning with automatic emergency braking, blind spot monitoring, lane departure warning, rear cross-traffic monitoring, and front and rear parking sensors.

Moving up to the Premium Plus variant adds keyless entry and starting, adjustable ambient lighting, lane departure steering assist and a 360-degree parking camera. The Technology Package, only available on the higher trim level, includes Amazon Alexa, navigation, traffic-sign recognition, wireless Apple CarPlay and Android Auto , and a Sonos sound system. In addition to the extra power, Q3 45 models also gain more options for wheel designs and interior colors.

Pricing and Availability

Audi’s 2024 Q3 will go on sale later this year. Pricing (including an $1,195 delivery charge) is as follows:

• 40 TFSI Premium: $38,195
• 40 TFSI Premium Plus: $40,995
• 45 TFSI S Line Premium: $40,595
• 45 TFSI S Line Premium Plus: $43,395

Best of Moscow by high speed train

By shuguley , February 15, 2014 in Regent Seven Seas Cruises

Recommended Posts

Sure would appreciate someone who has taken "Best of Moscow by high speed train" from St. Petersburg could please share their impressions of this shore excursion. From the description this sounds like a very long day.

Wondering how the 4 hour train trip was in terms of accommodations, etc. Also what time did you leave the ship and what time at night did you return? Were both legs of the trip on the high speed rail (I read that slower trains also travel the same tracks)?

My wife and I are considering this excursion. We thought that if we are making all the effort to go to Russia then how could we pass up going to Moscow, walking in Red Square, seeing St. Basil, etc.

If you are considering this on the 2015 June Baltic cruise on Voyager; my suggestion is don't. There is so much to do in St. Petersburg and although a train is one of my favorite ways to travel the time would be far better spent in St. P.

Thanks for the advice. Yes, this would be on the Voyager during the 2015 season but not yet sure exactly which cruise.

We did the Moscow excursion "on a different luxury line", but from your brief description it sounds very much like the same trip, so I will operate on that assumption. It is a VERY long day! We left the ship at 5:30 AM and returned at 12:30 AM. The highspeed train trip is comfortable, and while they call it "Business Class" it does not compare well to the equivalent class on say Rail Europe. When we did it in 2011, we did have highspeed both ways, and the trip back seemed much longer as the adrenaline and excitement had worn off!:D

Moscow itself is not that terribly different from any other big city in the world, but this Cold War kid never thought he would ever stand in Red Square, never mind walk the grounds of The Kremlin, or tour The Kremlin Palace, or see (but not visit) Lenin's Tomb, or visit The Armoury. But he did, and he loved every minute of it! Yes, it is a long day, and you barely scratch a scratch on the surface, but it is worth it. There is a tremendous amount to see in St. Petersburg, but every Baltic cruise goes to St. Petersburg, so you can go back if you choose to. Not every cruiseline offers you the chance to see Moscow.

I have not personally done this tour, but our last time in St Petersburg, the private guide that we hired for a day was leading the regent tour to Moscow on the high speed train the next day. He said it was way better than the previous alternative, which was flying to Moscow and back. He said that you actually got to Moscow faster because you didn't have to deal with airline checkin etc. it did seem like a very long day to me, and there is so much to see and do in st. Petersburg that I didn't consider doing it.

We toured to Moscow from St. Petersburg via the hi-speed SAPSAN train last September, from a Baltic cruise on the Oceania Marina. You need to have a two-night, three day port call in St. Petersburg to take this tour because the tour typically leaves the ship around 5:00 - 5:30 AM and doesn't return until after midnight the next day. We didn't take the ship's tour; we made private arrangements with TravelAllRussia for three days of touring, the first and third days in St. Petersburg and the second day the tour to Moscow by train. Our cost for the private tour for three days was about the same as what the ship charged for the excursion to Moscow alone. There are a number of private tour agencies that operate in St. Petersburg and offer the Moscow train tours; we would strongly recommend them over the ship's tours.

All three days had private guides with car and driver. The second day, the driver picked us up at the ship and took us to the train, but we were alone on the train, and met in Moscow by the guide on the station platform. After our tour and dinner, we were brought back to the train and after the return train trip met by the driver and taken back to the ship. Because you are alone on the train you must have your own Russian visas.

If this is your first visit to St. Petersburg, I would agree there is much more to see there. We found Moscow somewhat a disappointment, particularly Red Square. The Kremlin and the cathedral in Red Square were also worth seeing. But the best thing we saw was the Moscow subway! I worked for the Washington Metro system back in the 1980s as it grew from 40 to 80 miles and although I was in the computer area, I learned a lot about the challenges of running a subway system. We used the Moscow system to get across the city from where we had dinner to the train station, and I was amazed at the cleanliness', speed of operation, the short headways maintained, and the courtesy of everyone involved. A very impressive experience!

We had been to St. Petersburg before, and so had the time to take a day and go to Moscow. Also, I really like trains, and the SAPSAN is a German train set running on Russian rails. Seats are like first class domestic air, spacious but not too plush or comfortable, but with enough room. Not too much recline, and almost 8 hours on the train in two shots is a lot for an old man. They come through and sell drinks, candy, etc. but the sellers don't speak English and no one around us helped, so we had just poor coffee once coming, and brought stuff with us for the trip back. Not too much to see from the train either, particularly on the return when it is night the whole way.

If you decide to go, take a private tour and avoid the overly expensive ship's tour. I'm glad we did it, but wouldn't bother to repeat the tour; we've seen Moscow.

Thanks so much to all of you for the thorough and thought insight. Yhe information you have provided is most helpful.

countflorida: Your detailed post is very helpful. We are not quite ready for a Baltic cruise but should do so within a year. Time enough to do our pre travel research, bookings and visa gathering.:) Thank you!

Sure would appreciate someone who has taken "Best of Moscow by high speed train" from St. Petersburg could please share their impressions of this shore excursion. From the description this sounds like a very long day.   Wondering how the 4 hour train trip was in terms of accommodations, etc. Also what time did you leave the ship and what time at night did you return? Were both legs of the trip on the high speed rail (I read that slower trains also travel the same tracks)?   My wife and I are considering this excursion. We thought that if we are making all the effort to go to Russia then how could we pass up going to Moscow, walking in Red Square, seeing St. Basil, etc.

I did this on Seabourn. IMO DONT. Take Aeroflop (er Aeroflot). The train has non folding seats where you are literally knee to knee with your fellow passenger (facing each other). Further they don't believe in air conditioning. It's also the worlds slowed bullet train. I think I would have found more enjoyment wandering around the St. Petersburg and Moscow airports.

Countflorida,

This is a little off topic,, however we had planned a river cruise in Russia but decided we would rather stay on land and have booked about two weeks with Travel-All-Russia using the private guide and driver. I'm curious as to how you found them as a tour company.

The guides they provided were fine. We had a different guide each of the days in St. Petersburg, but both were flexible, pleasant, knowledgeable and spoke English very well, as did the guide in Moscow, incidentally. She was a bit aloof, distant, not too friendly, but otherwise fine. In fact, she was the one who suggested taking the Metro, which unexpectedly became one of the highlights of the Moscow excursion. If I have a complaint with AllTravelRussia, it is with their plan and its execution (more later).

I had requested emphasis on World War II (in Russia, the Great Patriotic War) sites and info. In scheduling us, they weren't careful about dates and a couple of the sites we wanted to see were scheduled on the third day, after we'd been to Moscow. But both sites were closed that day of the week, and that info was readily available, right on web sites describing them. Also, the included meals (lunches in St. Pete, dinner in Moscow) were not what we asked for: light meals with some choices, so we could avoid things we didn't like and choose things we did like. My request was ignored; we were given full Russian meals with a fixed menu, no choice. On the first day, a fish dish was the entre, but I am allergic to fish. Fortunately, I had the e-mail I'd sent with me and showed it to the guide, and she was able to change my entre to chicken, which was very good actually. But we didn't want a 3-4 course lunches or dinner (in Moscow). We had the guide drop the lunch the third day, although we never got any credit or refund. But, particularly in contrast to the ship's tours, the prices were so reasonable we didn't worry too much about it.

The people who were on the ship's tour to Moscow saw us boarding the same train for which they were forced to queue up and wait on the way back, and asked us what we had done. I was candid and open so they were not happy when I explained what we had arranged and particularly what it had cost. Also, when we returned to the ship, we found they had laid on a late supper for those who had gone to Moscow, so up we went and had something. Well, it turns out the late supper was supposed to be just for those on the ship's tour, but we and others on 'independent' tours, there were a dozen or more of us, crashed the party, actually got there first, and they didn't realize it until the larger group arrived and there weren't enough tables/places set. By that time, the 'independents' had all gotten served and were eating; what could they do?

A couple from the larger group sat down with us and asked us about our tour, and they were the ones I told about our arrangement and its cost. They turned to others who’d been with them and announced the details, loudly enough so the whole room heard, which started a lot of bitching and complaining. I gathered they weren't very happy with the ship's tour to begin with, and this was the straw that broke the camel's back. We finished up and beat it out of there, but overheard later that one of the excursion staff came to check on something and ran into a real mess. I caught a cold on the trip, which forced me to bed the second day following in Tallinn, so by the time we reappeared we heard about the contretemps' but apparently no one recalled who started it, thankfully.

Because of what happened to us, I would probably not use AllTravelRussia if I were to go again, or if I did, I would be sure to get confirmation of every detail of the tour. They do have good reviews generally, and we were certainly helped by their visa department and liked the guides and drivers. Their weakness, I say now with full 20:20 hindsight, is that once the sales person who plans the tour, sells it to you and collects your money, he (or she) transfers the plan to their Russia office for implementation; there is no follow-up to make sure it gets done right. And that is where our problems arose; we paid for a custom tour but got a standard package with a few destinations switched, and no one checked them out, even to see when they were open the day we were scheduled to go. If you check every detail that’s important to you, it should be OK, but that’s a hell of a way to have to do business, in my opinion.

Thank you for the 20/20 hindsight observation on your Russian tour operator, and better priced than the ship's excursion cost.

Thanks very much for the feedback.

We had the same experience as you so far as price. We originally booked a Viking Cruise but, hearing some things about the river cruises that made us unhappy, looked into other options. T-A-R cost the same or less than a cruise and had us in hotels for 11 days. We opted for the private tour. They have three tour levels, based on hotels. We originally opted for the four star as it did not cost much more than the three star hotels. Finally we decided to throw it all in and upgraded to five star. In Moscow we will be at the newly opened Kempinsky which is two blocks from Red Square. In St. Petersburg it is the Grand Hotel Europe, one of the most vaunted luxury hotels in Russia. Location is important for us as the tours use up only part of the day so being in the center of everything for our independent touring is important. As with many other cities, the less you pay, the farther out of the center of town you are.

We have been working with our salesman in D.C. and he seems to get back to us with the changes we want. He recently returned from Russia so is up on everything. When I asked they said they paid the full TA commission if I wanted so I got my usual TA on board so he is watching our back and giving us that extra level of comfort. He also set up our air, which I know pays him little or nothing, and got us business class for much less than T-A-R wanted for economy, though it took working for a while with a consolidator. He's happy to get his 10 percent on this trip without having booked it. He also took care of the trip insurance. We've been doing a lot of research on the CC sister site Trip Advisor and will write a report there. We will, I guess, become a source of info for CC members after having spent 5 days in Moscow and 6 in SP.
