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.

The Evolution Of Cruise Control And How It Works Today

Cruise control is one of the most useful safety and convenience features in modern cars, here is its history and how it works.

• Cruise control is a common feature in modern cars, making driving easier and potentially saving money on gas.
• Ralph Teetor, a sightless engineer, created the first cruise control in 1948, influencing the majority of cars today.
• Adaptive cruise control uses radar sensors to maintain a safe distance from vehicles ahead, enhancing safety and convenience.

It is probably instinct for you to be driving along a freeway and clicking on cruise control, giving your foot a rest, and watching the road. You probably don't even think about it now as you cruise along the stretch of road where you usually get to work or to see family regularly.

Or, you could be a driver who doesn't realize that your car features it, but, cruise control is featured in the majority of modern cars, whether that be a new electric car, a frugal hybrid car , a pick-up truck, a sports car, or a powerful sedan . All are likely to boast cruise control, or at the very least, it comes as an optional extra. Cruise control is one of the modern auto world's most useful and convenient features that not only makes your life easier but, also could potentially save you money on gas. Something we all need now that gas prices have recently gone up .

If you are like us and like to know how cars and electric cars work , you have probably thought to yourself before, how does cruise control work? Modern examples of cruise control have come a long way since the original model, and have become a safety measure in cars, so it is now an integral part of driving for a lot of people. For these reasons, we have scoured a wide range of sources to find out where cruise control came from, how it works, what cars feature cruise control, and how it has evolved from the first example, to what it is today.

In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from various Kia's website, Ford's website, and other authoritative sources, including Kelley Blue Book, The Rolls-Royce and Bentley Technical Library, The Smithsonian Magazine, MIT, Car Buzz, JD Power, Department Of Energy.gov, and Fuel Economy.gov.

How Car Engines Work: The Difference Between Gasoline And Diesel Engines

The beginning of cruise control.

The earliest known example of cruise control was created by an engineer named Ralph Teetor in 1948 . Legend has it that the idea came to him after being driven by an acquaintance who would slow down his driving every time he wanted to talk to Ralph. Ralph Teetor was sightless and, according to his family, had a 'legendary sense of touch', so the small deviations in speed would have been noticeable to him.

Others, including his family members, have said that the mandatory gas-saving speed limit of 35 MPH imposed by the American government during WWII could have also been an influence. The increased need for road safety could have played a part. For whatever reason, Ralph Teetor created something that has gone on to influence nearly all the cars on our roads today.

The first example of cruise control was called the Speedostat, and consisted of a dashboard speed selector connected to an engine compartment mechanism. As the driver-set speed got closer, the governor mechanism overcame spring tension to activate a piston capable of pushing back against the gas pedal, making it hard for the driver to push down the gas and gain any more speed until it was deactivated. Teetor obtained a patent for the Speedostat in 1950.

Early Models With Cruise Control

Over the next 5 years after 1950, the Speedostat was improved and a speed lock, which consists of an electro-magnetic motor that allows the driver to reach the needed speed and tap the brakes to maintain the speed, was added.

The first automaker that offered the Speedostat as an optional extra in their luxury models was Chrysler in 1958. The 1950s Chrysler models that feature the early version of cruise control are:

• 1958 Chrysler Imperial
• 1958 Chrysler New Yorker
• 1958 Chrysler Windsor

A couple of years later, Cadillac offered cruise control, as they had re-named it, in all of their models as an optional extra. The earliest Cadillac models to feature cruise control are:

• 1960 Cadillac deVille
• 1960 Cadillac Eldorado
• 1960 Cadillac Coupe deVille

How Cruise Control Has Progressed

Cruise control was not seen as a needed addition to cars until 1973 when an oil embargo against the U.S.A. created the need to save gas wherever possible. Meaning, that the implementation of cruise control became far more widespread and more than just a convenient feature to have. It became a gas-saving device that was needed at the time. Today, cruise control is one of the most common features of modern cars, alongside advanced safety features, which make the roads a safer place .

The change in cruise control comes in the form of throttle control and works in the following steps:

• Speed is selected by the driver via buttons on the steering wheel or dashboard (dependent on the car model).
• An electric motor (part of cruise control which is managed by your car's engine management unit), controls the position of the throttle with assistance from sensors and an actuator.
• The throttle position is set at the angle where the right amount of air can be let into the combustion chamber of the engine and the right amount of fuel can be injected to match your desired speed.
• The throttle is held in that position until you deactivate the cruise control by pressing the brake or accelerator to either increase or decrease your car's speed manually.
• Your car's cruise control may also accelerate or decelerate depending on the road surface and inclination of the road, but this depends on what car you have (we will cover this below).

Volvo Engine Teardown Reveals How Time And Use Affects Precision Components

How cruise control works in modern vehicles.

With more and more cars on our roads than ever before, just setting a speed and leaving at that speed would be great. It would make every journey a lot easier, but, of course, there are other road users to think about. This is how cruise control has become a very handy safety feature as well as a good way of saving fuel , getting a long driving range from your car , and making your trip easier.

In modern cars, radar-controlled cruise control, or adaptive cruise control, is used extensively to ensure you have a convenient ride and your drive is safe. Adaptive cruise control uses the following components to keep you at a safe distance from a vehicle ahead of you:

• Radar sensor
• Digital signal processor
• Longitudinal controller

Like the use of cruise control, an actuator controls the position of your throttle at your desired speed. The main difference between older versions of cruise control and adaptive cruise control is that a radar is placed behind the grille of a car and will help to maintain a safe distance from other vehicles in front of you.

Information is passed from the mentioned adaptive cruise control components to your engine management computer and then to the actuator that controls the throttle and reduces, or increases your speed.

Why Automakers Use Cruise Control

Automakers like Ford have implemented Active Cruise Control in a lot of their cars , and it is an optional extra for a wide range of their models too. Like Ford, many automakers have said that the use of cruise control and adaptive cruise control is being implemented for the following reasons:

• To save fuel
• To provide a safer drive
• To help reduce fatigue and loss of concentration
• To help you stay within speed limits

The Benefits Of Convenience

One of the main things that cruise control or adaptive cruise control is beneficial for in the modern world, apart from safety, is for saving gas. With rising prices pretty much everywhere in everyone's lives, this may be of paramount importance to you.

According to Fuel Economy.gov, the use of cruise control can potentially help you save gas because there will be constant speed of driving upheld. The more you accelerate and decelerate, or change speeds, even unintentionally, the more gas you use. The Department Of Energy has also said that the use of cruise control can help you save gas by maintaining a constant speed on the highway or in low-traffic situations.

Honda VTEC: What It Is And How It Works

Models of modern cars with cruise control.

Most new and some used cars and pickup trucks, depending on the age, and on the auto market come with cruise control or adaptive cruise control as standard. Even if you buy one of 2024's most fuel-economical gas-powered cars , regardless of what engine is featured, it will likely come equipped with either cruise control or adaptive cruise control as standard.

Along with efficient engines that are boasted in mainstream cars , one of the best potential gas-saving features is cruise control. We have taken a look around and found some stand-out examples of pickup trucks and cars that feature cruise control as standard .

Best Trucks And SUVs With Cruise Control

Though pickup trucks are not the most fuel-economical vehicles on our roads, they can be made relatively fuel frugal thanks to their powertrains and features, that help to bring down their combined MPG rating. Of course, the speed you set your pickup truck or SUV at, and how you use cruise control, can affect your combined MPG.

We have written before about the best hybrid cars, trucks, and SUVs for 2024 and 2025 . From our list, the following pick-up trucks and SUVs not only feature some great luxury features, work capabilities, and powerful powertrains, but also feature cruise control or adaptive cruise control:

• 2025 Ford Ranger PHEV
• 2024 Jeep Grand Cherokee 4xe
• 2024 BMW X5 xDrive50e
• 2024 Porsche Cayenne E-Hybrid
• 2024 Kia Niro PHEV

Best Cars With Cruise Control

Featuring in many cars on the market at the moment, cruise control is very common. Adaptive cruise control, as a standard feature though, is a little less common in 2024 budget cars .

If you are looking at buying a new car in 2024 , it is always worth asking, of course, but it is likely that it will feature cruise control as standard. From its humble beginnings in the mid-20th century to the almost required safety and gas-saving device in modern cars, cruise control has had a long history. A history full of adaptations to suit the needs of the driver and the changing road environment. Cruise control has even been rolled out in a few motorbike models as well. It is becoming arguably necessary and common on our roads.

Wanna Know How Brake-By-Wire Works? Here's Your Explanation

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.

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.

Guide to Adaptive Cruise Control

How this convenience feature works to reduce your stress on long drives

Adaptive cruise control (ACC) is like traditional cruise control, but smarter. ACC systems allow you to set a desired speed until your vehicle encounters slower-moving traffic. Then it will brake to maintain a set distance from the car ahead. Once the traffic starts moving again or if there is no longer a car in the lane ahead, ACC will accelerate to resume the previous set speed. Although ACC systems may take some getting used to, our survey respondents told us they appreciated the stress relief the feature brings.

“I use the feature mostly on the freeway and in stop-and-go traffic. I find it reduces tension and fatigue,” wrote a 2020 Subaru Outback owner. A 2018 Audi Q5 driver agreed. “It is so nice to just set it and let the car worry about the traffic,” they told CR.

The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically.

Adaptive cruise control (ACC): Cruise control that also assists with acceleration and/or braking to maintain a driver-selected gap to the vehicle in front. Some systems can come to a stop and continue while others cannot. If the car comes to a full stop, you may have to press the accelerator or a button on the steering wheel to start moving again.

Not all systems work at low speeds, so drivers who plan to use ACC in slow traffic should check the limitations of any system they plan to buy. These particular systems will often have the words “traffic jam” or “stop and go” in their name.

These features are usually activated using a button on the steering wheel with the image of a car next to a speedometer with an arrow pointing at it. A conventional cruise control system does not automatically keep a set distance away from the car in front, and it is indicated by a similar logo without the car next to the speedometer. A tip to know if your car has adaptive cruise control or regular cruise control is to look for the “gap distance” button, which usually shows a symbol of a car with horizontal distance bars in front. This button will determine how much space your car leaves between its front bumper and the rear of the car it is following.

In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver assistance systems on their model-year 2017 to 2022 cars. Respondents answered questions about their satisfaction with the systems. The survey covered about 47,000 vehicles. Most respondents told us they were “very satisfied” with ACC. Satisfaction was higher for older drivers.

OVERALL SATISFACTION

What to Look For in an Adaptive Cruise Control System

Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. Some do a better job than others at recognizing merging traffic and automatically apply the brakes, while others wait too long to slow your car, requiring the driver to take control—especially when a vehicle in front of you cuts you off with a close merge.

“Most ACC systems can only be set to speeds above 20 mph but will slow the vehicle to speeds below that in stop-and-go traffic,” she says. “There are a few systems out there that don’t bring the car all the way to a stop but instead just shut off at low speeds. That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive.

ACC is meant for convenience, not as a replacement for an alert driver, Funkhouser says. So don’t use adaptive cruise control as an excuse to get distracted. “Just because the car is controlling your speed doesn’t mean that you can check out,” she says. “These systems do not do well at detecting or slowing for vehicles ahead if you approach them at a high rate of speed. The driver should always be monitoring the surrounding traffic and looking ahead for potential hazards.”

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
• the wipers are set to the maximum speed setting in heavy rain

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.

Cruise control is a valuable feature in many modern vehicles, enhancing convenience and efficiency, especially during long drives. This guide delves into the intricacies of using cruise control, offering expert insights, technical details, safety tips, and more.

​ Understanding Cruise Control

​ what is cruise control.

Cruise control is an electronic system that allows a vehicle to maintain a steady speed set by the driver . Cruise control is designed to be used on roadways without frequent stops. It’s ideal for use on highways and long stretches of road with minimal stops or turns.

​ Types of Cruise Control

• Standard cruise control maintains a set speed until manually overridden.
• Advanced systems, like adaptive cruise control , automatically adjust speed based on traffic conditions.

​ Operating Cruise Control

• Adjusting Speed

Before activating cruise control, ensure conditions are safe. It’s not advisable to use cruise control in hazardous weather or heavy traffic.

​ Safety Tips

Remain vigilant and ready to deactivate cruise control instantly in case of an emergency or changing traffic conditions.

Speed Limits

Always adhere to speed limits. Cruise control should not be used to maintain speeds above legal limits.

​ Advanced Features

Adaptive Cruise Control

This modern feature uses sensors and radar to maintain a safe distance from the vehicle ahead, adjusting speed automatically.

​ 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.

Tesla Full Self-Driving (FSD) Beta

Tesla’s FSD Beta represents a leap forward in autonomous driving technology. It’s not just a cruise control system but an advanced driver-assistance system capable of navigating complex driving scenarios. Key features include automatic lane changes, stop sign and traffic light recognition, and the ability to navigate city streets. While it offers substantial automation, it still requires driver supervision and isn’t fully autonomous.

GM's Super Cruise

General Motors’ Super Cruise system is available in select Cadillac models and provides hands-free driving assistance on compatible highways.

​ Real-World Impact

Cruise control technology not only adds convenience to driving but also significantly impacts safety and efficiency. This section delves into the real-world implications of using cruise control, supported by safety statistics and research findings.

The integration of cruise control in vehicles has been a game-changer in terms of driving safety and efficiency. Here are some key impacts:

Reduced Driver Fatigue : Continuous concentration over long drives can lead to driver fatigue, a leading cause of road accidents. Cruise control allows drivers to maintain a constant speed without constant pedal adjustment, reducing the physical and mental strain during long journeys.

Improved Fuel Efficiency : By maintaining a steady speed, cruise control helps in reducing fuel consumption. Studies have shown that erratic speed variations can lead to higher fuel consumption, whereas maintaining a consistent speed optimizes fuel efficiency.

Safety Statistics : Research indicates that the use of cruise control can lead to a reduction in speed-related accidents. However, it’s crucial to note that over-reliance on cruise control in inappropriate conditions (like city driving or in heavy traffic) can negate these safety benefits.

Impact on Traffic Flow : When used widely, cruise control can contribute to smoother traffic flow on highways. Consistent speeds help in reducing the frequency of braking and acceleration among vehicles, leading to less congestion and smoother traffic movement.

It’s important to balance the use of cruise control with active driving engagement, ensuring that safety is always the top priority.

For a deeper understanding of cruise control and its various aspects, it’s always beneficial to refer to your vehicle’s manual and seek guidance from automotive professionals.

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]

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.

Related: What Is an Immobilizer and Does My Car Have One?

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.

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.

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.

Can You Use Cruise Control With Manual Transmission?

Cruise control, even though it has been around for a while, has been one of the best features of a car especially if you are looking at the safety of the vehicle. But while cruise control tends to be a standard feature in cars with automatic transmission, you might wonder if manual cars have it. So, can you cruise control with a manual transmission?

You can cruise control with a manual transmission. It doesn’t work half as well as it does with automatic transmissions as it still regulates the car’s speed when you are cruising. But the system tends to disengage the moment you slow down or when you press the clutch.

In that regard, while cruise control does indeed work with cars with manual transmissions, you shouldn’t expect it to work perfectly at all or even close to how it works on cars with automatic transmissions. Still, having cruise control on a manual car can still be something to be happy about especially when it comes to your overall safety.

Is cruise control available on cars with manual transmissions?

When you look at how cruise control works and how manual transmission cars are basically a thing of the past, you would probably think that they are not compatible with one another. And there is a good reason for that especially when you consider that cruise control works really great on cars with automatic transmissions and how it seemingly should only work on them.

However, what you need to know is that cruise control is indeed available on cars with manual transmissions. Yes, you read that right. Even though it might seem like cruise control and manual transmission don’t seem to go well together, this is still a feature that is very much present in cars with manual transmissions.

The reason why cruise control is still available on manual transmission cars is, of course, for safety and for convenience. You can never really deny the fact that cruise control is very useful when it comes to cruising on an open road especially during long drives as it basically allows you to fix your speed at certain levels. And when applied on a manual transmission car, it becomes quite useful as well especially when you consider how it can be exhausting to keep your car on a steady speed level when you are driving a stick shift car.

Of course, because modern cars now come with electronic speed signals and electronic accelerator signals, it really isn’t difficult to integrate cruise control into cars that come with manual transmissions. Even modern motorbikes also have cruise control nowadays given how useful the feature is for any kind of vehicle.

How does adaptive cruise control work with a manual transmission?

While cruise control may be available on cars with manual transmissions, don’t expect it to work as well as it does on a car with an automatic transmission. In some cases, you would even say that cruise control works only half as well as it does on stick shift cars than it does with an automatic car.

For starters, when you engage the cruise control function on a car with a manual transmission, it will work in a similar manner as it does on a car with an automatic transmission. However, the moment you step on the clutch or when you slow down or come to a full stop, the system will automatically disengage unlike how it stays turned on in a car that runs on an automatic transmission system.

As such, when you have to switch gears, you need to re-engage the cruise control function again. However, this doesn’t seem to be much of a big deal for manual transmission drivers because of how switching gears means you are actually slowing down or speeding up. That naturally means that you actually don’t have to use cruise control.

Meanwhile, when the RPM gets to levels that are too low or too high, the cruise control function automatically disengages as well. However, it won’t disengage if it detects traffic that is slower than you as long as the difference in speeds isn’t that too big. But when the speed difference is so big that you need to downshift, the system will automatically disengage.

Is low-speed follow available on a manual transmission?

No, low-speed follow is not a feature that is available on cars with manual transmission. Low-speed follow may be great for cars running on automatic transmissions but it is close to impossible to integrate it with stick shift cars because of how it will require you to shift your gears a lot when you are driving a car with a manual transmission.

Can you put cruise control in a car that doesn’t have it?

Even if you have an older car that doesn’t have cruise control, you shouldn’t worry because you can still have it added to your car. Yes, that is right. You can have an aftermarket cruise control added to your car regardless of whether it may be manual or automatic if it originally didn’t come with cruise control. And there are plenty of reasons why you should have cruise control in your car.

Long rides will end up becoming more comfortable if you have cruise control. Of course, because of the consistent speeds your car will be running on, it will end up having better mileage. And when you are in the middle of long drives, you will less likely end up getting fatigued when you have cruise control engaged. 

Cruise control kit for manual transmission

In case you want cruise control to be added to your car, you can simply buy a cruise control kit and have it installed in your car. This cruise control kit from Rostra is a good choice because of how comparatively affordable it is and how it can be installed in manual transmission cars. However, you would need to buy a separate clutch switch for it to be installed in a car with a manual transmission.

Does Cruise Control Really Save You Gas and Money?

D o you like to use your cruise control feature on your car? Obviously in stop-and-go traffic and around-town driving it’s not something we gravitate but on those longer drives on the highway it’s definitely a go-to.

I love using cruise control on road trips or drives that have you on traffic-free highway driving for at least 30 minutes because it keeps my lead-foot in check saving me from a possible speeding ticket. Also I love the feeling of saving gas which means saving money as well, right?

And if cruise control does save gas, thus money, is it a measurable difference?

Well, it’s not really surprising that yes, using your cruise control absolutely helps you prolong the gas in your tank. According to the Motor Trend cruising along on highways means avoiding the inconsistency on the gas pedal. The inevitable speed-up/slow-down momentum is absent and that’s where we waste the most fuel.

However, if you’re driving on rolling hills, it’s best not to use your cruise control because that’s hard work on your car trying to stay the pace by slowing down and then having to speed up back and forth during the ups and downs of the hilly drive. It’s better for you to do it manually according to Motor Trend.

So how much does using cruise control really save you? Well, first of all it depends if you even get to use it. For many it’s just not part of your driving lifestyle, but for those that do hit the highways where it’s useful, you can save between $25 and $75 annually according to the Net Pay Advance website. This coincides with the ever fluctuating price of gas.

If you’re an “ever little bit of savings helps” kind of person, then the savings is worth it, especially if your driving lifestyle is conducive to using cruise control.

What is android auto.

Hey Google, how's the traffic to work?

Juggling tasks while driving is risky, but it's a common habit. Whether you're checking directions on Google Maps, playing your downloaded songs from Spotify , or sending a quick text, your eyes must remain on the road despite these distractions. The infotainment systems in modern cars, with their buggy and frustrating OSes, make this a tall order. This is where Android Auto steps in, offering features of the best Android phones while helping drivers focus on what matters most. Here's how it works.

What is Android Auto, and how does it work?

Android Auto transforms your car's dashboard into a smart mobile command center. Plug your Android smartphone into your car using a USB cable or connect wirelessly via Wi-Fi or mobile data, and your car's dashboard mirrors the familiar Android interface. You can then enjoy apps like Waze, WhatsApp, and Audible on a clutter-free, driver-focused interface.

Check out Google's list of compatible apps if you're curious if your favorite app works with Android Auto.

Android Auto brings Google Assistant to your dashboard for easy hands-free access. It also sits atop your car's infotainment setup, letting you switch between Android Auto and your vehicle's features.

How can android auto use google assistant.

Google Assistant seamlessly integrates into Android Auto. Simple voice commands like "Hey Google" or tapping the microphone icon activate the assistant. This feature lets you easily set reminders, make calls, and navigate routes hands-free.

To get started, ask for directions to the nearest gas station or parking spot. Although it can't tackle vehicle-specific functions, like adjusting the seats, it handles tasks like playing music. It also controls smart home devices with an active data connection.

How to find out if your phone works with android auto.

If you prefer a wired connection, connect Android Auto to your car display using a high-quality USB cable if your Android phone runs version 8.0 or higher.

For a wireless connection, your device should support 5GHz Wi-Fi and run on Android 11.0 or higher. Google and Samsung smartphones using Android 10.0 meet this requirement. Google also says that Samsung Galaxy S8, S8+, and Note 8 with Android 9.0 are compatible.

If your phone runs Android 9.0 or below, download the Android Auto app. It's built into phones with Android 10 and above. Find out what software your phone runs by going to Settings > About > Android Version . Also, check Settings > System > System Update and see if a newer software version is available.

It's rare to find a carmaker that doesn't include Android Auto in its latest models. The odds are in your favor, with more than 500 vehicles supporting Android Auto. Use our latest guide to check if your new car supports this feature.

Google provides a list of countries that support Android Auto, along with compatible vehicles and stereos if you have aftermarket upgrades.

How to set up Android Auto in your vehicle with a USB cable

Connecting your phone to your car with a USB cable is all it takes to use Android Auto. Your phone must have the Android Auto software installed, and your car must support the app. Here's how to do it:

• Make sure your phone and car meet the requirements.
• Turn on your mobile data.
• Put your car in park (P) and turn on the infotainment system.
• Connect a USB cable to your car's USB port and the other end to your Android phone.
• Select the Android Auto symbol on your car's display if Android Auto doesn't start automatically.

• Look for a Welcome to Android Auto screen on your smartphone. Check your car's display for confirmation prompts if it doesn't appear.

Does Android Auto take control of your car?

Android Auto does not allow control of built-in car systems, such as cruise control or air conditioning. However, it interacts minimally with the vehicle, such as muting music streams when a warning or alert sounds.

Google Maps for Android Auto will collect battery data from electric cars in future updates, as Google announced during CES 2024 . With this feature, the app tracks and displays real-time battery information and adjusts your driving route autonomously according to the car's battery needs.

Smarter and uniform dashboard across different cars
