We’re sorry we don’t support the car you are looking for. Please enter its make, model, and year below so that we can add support for it.

Operating Cruise Control

Step 1 Locate your car's cruise control switches.

  • Check your car's operating manual if you are unable to find the cruise control switches.

Step 2 Study the layout of the switches.

  • Many cars have additional buttons to increase or decrease speed (marked by a +/-) when using cruise control.

Step 3 Drive your car until you reach your desired speed and hit “SET.”

  • For some car models, cruise control will not operate below a certain speed, such as 40 miles (64 km) per hour.

Step 4 Stop cruise control whenever you need to.

  • To stop cruise control briefly (such as when a car in front of you brakes), just press the brake as you normally would.
  • If you are driving a manual, you can also disengage cruise control by pressing the clutch.
  • If you are completely done using cruise control, you can press the “OFF” or "ON/OFF" switch.
  • If your car has a cruise control “CANCEL” switch, you can also press that to stop it.

Step 5 Resume cruise control, if you want.

  • If your car has a +/- button for cruise control, press this when you want to raise or lower your car's speed.

Using Cruise Control Safely and Efficiently

Step 1 Reserve cruise control for the open road.

  • Using cruise control on busy streets can also be dangerous. Since you yourself are not in complete control of your car, you may be paying less attention. You might brake or react to other cars more slowly than normal, increasing the chance of an accident.

Step 2 Avoid using cruise control in hazardous conditions.

  • Wet or snowy roads
  • Hilly, steep, or mountainous areas
  • Winding roads

Step 3 Stay focused on the road.

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

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

Cruise Control in a Car

What is cruise control in a car?

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

How does the cruise control system work?

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

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

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

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

How to use cruise control?

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

Here are the steps to use cruise control.

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

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

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

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

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

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

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

How to install cruise control in a car?

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

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

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

Adaptive cruise control

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

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

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

Pros and cons of cruise control

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

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

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

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

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

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

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

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

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

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

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

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

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

Cruise control vs adaptive cruise control: Key differences

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

What is the difference between cruise control and speed limiter?

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

List of cruise control cars In India

Cruise control is a feature that we can see in a lot of cars. Gone are the days when this feature was limited to premium vehicles. Even vehicles with affordable price tags are equipped with intelligent features. Here’s the list of popular cars with the automatic cruising system.

cruise control

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.

car cruise mode

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.

car cruise mode

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.

car cruise mode

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.

car cruise mode

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.

How to Use Cruise Control Safely

Everything you need to know for safe, stress-free driving with your car's cruise-control system.

clock, font, icon, circle, illustration, logo, stopwatch, home accessories, symbol, graphic design,

Its Job Is to Maintain Speed

Cruise control's primary function is to maintain the speed of your choosing, relieving you of needing to keep your foot on the throttle. Virtually all cars on the road today rely on an electronic control module—a computer—to monitor the vehicle's speed and to readjust it as needed to hold the speed you've chosen regardless of the road's gradient.

 

Know the Controls

You operate cruise control by either a stalk on the steering column or several buttons on the steering wheel. These include an on-off switch; a "set" button to select the speed you want the car to maintain; and buttons or switches marked "+" and "—" that increase or decrease the speed after it has been set, often in 1-mph increments. A "cancel" button disengages the cruise-control system without shutting it off entirely, allowing the car to coast. (Cars with stalk-operated cruise control have a "cancel" position that you move the stalk to in order to disengage the system.) A "resume" function or button brings the car back to its previously set speed. Braking or depressing the clutch at any time will also cancel cruise control. Should you need to make a quick pass, you can always override the preset speed by simply pressing down further on the gas pedal.

Adaptive Cruise's Added Features

Many newer cars offer what's known as adaptive cruise control, sometimes also called active cruise. It works in the same way as conventional cruise systems and additionally relies on front-mounted radar , cameras, or sensors to detect the presence of vehicles directly ahead in your lane. This enables adaptive cruise-control systems to maintain a set distance from the vehicle in front no matter how it varies its speed.

Adaptive systems allow you to adjust how closely your vehicle follows the one ahead but are programmed so that they always maintain at least a safe minimum following distance. Some of these systems also have the ability to brake and even come to a complete stop in city traffic and, depending on the vehicle, automatically accelerate without the driver pressing the gas pedal when traffic starts to move again.

Semi-Autonomous Cruise Control

Finally, the newest, most advanced cruise control systems, such as such as Nissan ProPilot Assist, Subaru EyeSight, and Audi Traffic Jam Assist, are semi-automated driving assistants that combine adaptive cruise control with lane-keeping assist, which self-steers the car gently to keep it in lane if you let it wander out—although you can only take your hands off the wheel for a few seconds before the system sounds alarms and then shuts off.

.css-1rvrtxn{font-family:Gliko,Gliko-fallback,Gliko-roboto,Gliko-local,Georgia,Times,Serif;font-size:1.625rem;line-height:1.2;margin:0rem;-webkit-text-decoration:underline;text-decoration:underline;text-decoration-color:#DBCA8B;text-decoration-thickness:0.25rem;}@media(max-width: 48rem){.css-1rvrtxn{font-size:2.25rem;line-height:1.1;}}@media(min-width: 48rem){.css-1rvrtxn{font-size:2.625rem;line-height:1.1;}}@media(min-width: 64rem){.css-1rvrtxn{font-size:3rem;line-height:1.1;}}.css-1rvrtxn b,.css-1rvrtxn strong{font-family:inherit;font-weight:bold;}.css-1rvrtxn em,.css-1rvrtxn i{font-style:italic;font-family:inherit;} No matter what type of cruise control your car has, the rules for using it safely are the same.

Most of these systems also can autonomously negotiate only the most gentle curves on the interstate. Some semi-autonomous systems, such as those from Tesla and Mercedes-Benz , can do more, including steering the car into the adjacent lane while keeping enough distance from other cars.

Follow These Safety Rules

No matter which type of cruise control your car has, the guidelines for using it effectively and safely are the same:

  • Always remain alert and aware of other traffic, and be ready to take control and brake or steer around obstacles, inattentive drivers, or emergency situations.
  • Think of even the most advanced adaptive and semi-autonomous cruise control systems as "dumb." They are programmed by humans and may react unpredictably in certain, unforeseen conditions. (See previous point: "remain alert.") Rain, snow, and fog can obscure radar signals and confuse cameras or sensors, sometimes disabling adaptive cruise control entirely. As with conventional cruise control, with an advanced cruise system you must always be prepared to take full control at a moment's notice.
  • Cruise control is still best suited for use on highways and in light traffic. If your vehicle has conventional (not adaptive) cruise control, be sure to leave adequate spacing between your car and those ahead, and be prepared to disengage the system by braking or tapping "cancel" as you creep up on other vehicles or get into heavy traffic.
  • Do not use cruise control in slippery conditions, including snowy or icy roads or rain-soaked roads awash in deep puddles. Most cruise systems will attempt to maintain your speed until you intervene, and on slippery roads that could cause you to momentarily lose traction, upsetting the car and potentially precipitating an accident.

Treat cruise control as a simple labor-saving convenience, however—but one that must be monitored—and you'll enjoy many miles of comfortable, stress-free travel.

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

car cruise mode

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 .

What is Cruise Control

Cruise Control Explained – All You Need to Know

Zutobi

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.

car cruise mode

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.

highway with heavy traffic

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.

winding road in the mountains

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.

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.

How does cruise control work.

car cruise mode

Cruise control is more than just a catchy name — it's a feature that you may just find in your own vehicle. There’s a good chance you might’ve even asked yourself “How does cruise control work?” after spotting it on your steering wheel. Read on to learn more.

What is cruise control?

Cruise control is an automated vehicle system that can manage your car’s acceleration to keep it traveling at a steady speed. This can be quite useful to drivers who are covering long distances on relatively straight roads, as it spares them the fatigue of keeping their foot on the gas for extended stretches of time. Other possible benefits include:

  • Increased fuel efficiency from keeping a constant speed.
  • Less distraction from speed adjustments, so the driver can pay more attention to the road.

Cruise control systems typically work by adjusting your car’s throttle, which moderates the air going to the engine. In older cars, this was done with a system of physical cables connected to the throttle valve, but newer cars have electronic systems that can adjust the car’s speed with an even higher degree of precision. A system of sensors constantly relays information about the car’s speed back to the cruise control system, which adjusts the throttle accordingly to maintain the desired speed.

The specifics of using a car’s cruise control vary quite a bit from car to car. It’s best practice to consult the owner’s manual for your car for precise information, but some basics are included below:

  • Most cruise control systems typically have a button labeled “Set.” When you press this button, the system will engage cruise control at whatever speed you’re currently travelling. Some systems may also have an option to set a higher speed by pressing or holding the button down.
  • Stepping on the brakes at any point will disengage the cruise control, while pressing the “Resume” button will return the car to the set speed.
  • There is typically also an “Off” button, which will automatically shut off the cruise control when pressed.
  • Most cruise control systems typically won’t activate below a certain speed limit. The exact limit may vary by car but is often somewhere in the range of 30-40 miles per hour.

Adaptive cruise control vs. standard cruise control

By now, you may have picked up on a potential drawback of cruise control — keeping a steady speed is harder to do (and possibly dangerous) when there are other drivers in front of you. This is why car makers invented adaptive cruise control.

With adaptive cruise control, your car uses radar and laser sensors to detect the speed of vehicles ahead and then adjusts your own speed accordingly to keep a safe distance. So, if the car in front of you slows down, your car will too. Once they’re out of the way, your adaptive cruise control will accelerate back to the speed you previously set. Standard cruise control, on the other hand, requires you to manually turn off the cruise control (or automatically disengage it by pressing on the brakes) when you notice traffic up ahead.

When to use cruise control

Cruise control was originally designed to be used on long drives and road trips when it’s possible to maintain a constant speed. Highway driving is still the typical time to deploy your cruise control, but the development of adaptive cruise control has made it possible to potentially use your cruise control for certain city driving scenarios as well.

When not to use cruise control

It’s also important to know when not to use cruise control. It's generally best to avoid using this feature when:

  • There’s a lot of traffic on the road, and it would be difficult to hold one steady speed for long.
  • The roads are wet or icy, as it may limit your ability to decelerate or stop quickly enough if you start hydroplaning .
  • You’re fatigued, as the ability to relax your legs may increase the risk of potentially falling asleep behind the wheel.

Cruise control is more than simply a modern convenience. In the right circumstances, it can potentially enhance your driving experience by reducing fatigue, increasing safety and improving fuel efficiency. If you’re still wondering “How does cruise control work?,” perhaps it’s time to take the leap and try it out for yourself the next time you’re shopping for a new car.

Cars in your comparison, driving 101: dos and don’ts when using cruise control.

Let this be your guide before you engage your car’s cruise control feature.

Autodeal

Cruise control is a feature that is becoming increasingly popular amongst brand new vehicles available in the Philippines. If you’ve noticed by now, in our car review we always check to see if this feature is available or not. Why? It’s because this feature is very useful and convenient, especially for those who take the expressways daily. It has become so rampant among modern cars, that almost all vehicles above the one-million-peso price point have this in their slew of high-tech toys.

If you have a vehicle already equipped with this feature, we are pretty sure that you are already familiar with how cruise control works. You get to your desired speed, turn on cruise control, set it, and you are good to go. The problem is, not everyone who knows this feature is aware of the dangers it can pose when not used correctly.

For that, here are the dos and don’ts when using your car’s cruise control. Have a safe cruising, everyone!

Do keep your foot on or near the pedals

pedals

Cruise control is really helpful in resting your right foot during long drives. However, no matter how tempting it could be, you should keep your foot on or near the accelerator and brake pedals so you can instantly react whenever you need to halt or increase your speed. Even if you have a car that comes with adaptive cruise control that will maintain a safe distance between you and the vehicle in front of you it is always best to have your foot on the brake. It’s still best to have an element of safety when it comes to you and your vehicle. Do not rely on safety such as autonomous braking as they are only there for emergencies.

Do stay mindful of your surroundings

open road

Just because you have cruise control or its adaptive form doesn’t mean the car is completely in charge of driving. You will still have to do the steering and other inputs. This is why you should stay mindful of your surroundings. While engaging your cruise control can mean resting while driving, you still have to keep yourself mindful of the things happening around you. Even when this feature is on, driving shouldn’t be distracted and your concentration should stay intact throughout the long drive. Remember, eyes on the road, not on your phone.

Do stay within a safe distance from the car in front

following distance

Regular cruise controls (as opposed to the adaptive type) can’t detect the car in front and automatically keep a certain distance from it. That’s why your focus is important so you can manually keep a safe distance between your car and the one you’re trailing. Simply put, less space between two vehicles means less braking distance, and can be very dangerous when you’re running 100 km/h. Remember the three-second rule. Remember that the cruise control available in mass-market vehicles isn’t as smart as what you would find in a Tesla or other higher-end luxury cars. 

Don’t let go of the steering wheel

dashboard

However tempting it is to let go of the steering wheel while cruising on a straight path, you really shouldn’t, at all cost. Road-leveling varies and might affect your car’s direction, so keeping both hands on the steering wheel will make sure that you’ll stay inside the lane. Even if your car is equipped with Lane Keep Assist (just like in the  Honda CR-V and Ford Everest ), remember that these features were only made to assist.

Besides, when presented with a situation where you need to abruptly change direction, both hands on the steering wheel are a whole lot better than fewer or no hands at all.

Don’t go beyond the speed limit

speed limit

It’s needless to say that speed limits should always be followed, which means the maximum speed you can go with your cruise control while on the highway is 100 km/h. Going beyond this number isn’t only dangerous to you, your passengers, and other road users, it’s also illegal and can cost you hefty fines

Don’t sit on the leftmost lane

left lane

As many of you already know, the leftmost lane is for overtaking only, you are not supposed to stay there long. In the Philippines, the law is to keep right except when overtaking. Why? Hogging the leftmost lane will slow down the traffic because no matter how fast you go, there will always be a car behind that’s faster than you.

There are many good reasons as to why hogging the leftmost lane is frowned upon, and most importantly illegal, but this one’s the most important: in case of emergencies, the leftmost lane of the road can stand as the emergency lane (since we generally don’t have one). Therefore, it should always be clear of vehicles so those cars that need to speed can pass through easily.

  • What is cruise control?

“Cruise control allows you to maintain a set speed without using the accelerator. Once you've selected the speed, you can take your foot off the accelerator and the vehicle will cruise at that speed.”

What Is Cruise Control

car cruise mode

Cruise control is a feature that comes in handy when you drive at a constant speed. It is an electric system that allows you to set your car to a specific speed, letting you take your foot off the accelerator pedal. So, it can ease foot-fatigue and stress over a long drive. Another great benefit to using cruise control is that you are going to have greater fuel efficiency. Your vehicle will consume much less fuel if you cruise at a steady speed rather than accelerating at each section of the open road. When you accelerate sharply, it makes your engine use more energy, and you could be using 60%  more fuel than one who uses cruise control. Ultimately, it's not hard to save on fuel if you let your vehicle automatically maintain a steady cruising speed.

The leading edge of cruise control today is adaptive cruise control. Almost all cars now will be equipped with this smart system. Just as conventional cruise control, adaptive cruise control allows you to set a desired travel speed. But the difference is that the adaptive cruise control maintains a safe distance between the car in front of you and your car at a consistent pace by using the forward-mounted sensors. For instance, if the car ahead of your vehicle begins to slow, adaptive cruise control will use the engine brake to automatically slow the pace of your vehicle and maintain the selected distance.  Many say adaptive cruise control is a step to autonomous cars in the future. But it is not quite fully autonomous driving, since you have to keep your hands on the wheel and be fully cognizant of the road.

How To Use Cruise Control

Typically, the cruise control buttons can be found on the right-hand side of the steering wheel. Depending on the car, the location of the controls can vary, but the functionality of the cruise control will usually be similar across the board. Here are the basic buttons you can use to operate cruise control.

ON/OFF : To set the cruise control, press the ON/OFF button. You will see the cruise light illuminate on the dashboard which means the system is activated. To turn the system off, press this button again.

Res + : Press this button if you want to increase the cruising speed. Each time you hit the button, the vehicle will accelerate by 1 mph. You can also use this button to resume your previously set speed.

Set - : This button will decrease the set speed. Each time you press the button, the cruising speed will decrease by 1 mph. Once you reached the desired speed, hit the “Set” button and the “Cruise Set” icon will appear on the dashboard. Then you can take your foot off the gas pedal and the car will maintain the speed for you.

Cancel : When it's time to cancel the cruise control mode, like when you exit the highway or if there is heavy traffic ahead, press this button to disengage the cruise control system. Or you can simply depress the brake pedal to cancel the system.

Safety Tips for Using Cruise Control

However smart the cruise control may be, there are some situations where you SHOULD NOT use the feature altogether. Here are some golden rules to live by when it comes to using your cruise control.

              

  • On wet roads, it could be dangerous to use cruise control. It will be less effective in the rain, and cruise control may upset the balance and reaction times under rainy conditions.     
  • During rush hour, it is a good idea to leave the cruise system off. With conventional cruise control, you will have to continuously turn it off when traffic slows down and you can get into an accident if you are distracted while it is active.
  • On challenging winding roads, you should not use cruise control. Note that cruise control is primarily designed to enable you to cruise on the highway at a set speed. If you are not doing so, it is best not to use it.

Moscow is testing FLYING taxis (PHOTOS + VIDEOS)

car cruise mode

In January 2021, ‘Hoversurf’, a Russian urban air mobility company, started testing its Hover drone taxi, a flying vehicle that can transport passengers and cargo, ‘Popular Mechanics’ magazine reports .

car cruise mode

The drone taxi is the size of a standard sedan car (5 m x 1.6 m), says TASS news agency, citing the press service of the Moscow city Department of Entrepreneurship and Innovative Development.

It can reach an altitude of 150 meters and cover a distance of up to 100 kilometers in one go. The drone taxi does not require the construction of special runways, as it can land on an ordinary parking lot and is also capable of maneuvering onto a parking lot and flying into a garage. It will be able to carry two people or up to 300 kilograms of cargo and to develop a speed of up to 200 km/h (124 mph).

car cruise mode

The drone taxi is currently being tested at an indoor arena of the Luzhniki Stadium. For the time being, the prototype is testing the ‘Lift & Cruise’ flight mode, whereby the take-off, landing and horizontal flight are taken care of by different groups of engines and is trialling a parachute system to be used in emergencies.

car cruise mode

Inventor and businessman Alex Atamanov, the founder of Hoversurf, began developing the drone taxi in 2018. In addition to this project, Hoversurf has a hoverbike project, which Atamanov presented in 2016.

Hoverbike

The hoverbike can fly for up to 40 minutes and reach a maximum speed of 96 km/h (59 mph). After its public testing at the ‘Startup Village’ conference in Skolkovo, the company received 3,500 pre-orders for its hoverbike. For the time being, the hoverbikes are sold one at a time, with each one taking a month to assemble, Atamanov said in an interview with Vc.ru in 2019.

The Hover Taxi now has more chances of entering mass production, Atamanov told the Popular Mechanics magazine. He said that by the spring of 2021, the Moscow City government has plans to build a new platform at Skolkovo for testing the drone: it will have a 5G signal and will make it possible to improve the drone’s AI-based control system, which maps routes, operates the drone and ensures flight safety.

car cruise mode

Hoversurf expects to be able to produce the first production models of its drone taxi in 2021. However, they will not be able to enter mass use until 2023-2025, when Russia gets a 5G network and adopts a law allowing the use of drones like these on the country’s territory.
