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

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

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

Understanding Cruise Control

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

How Does It Work?

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

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

The History of Cruise Control

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

Types of Cruise Control Systems

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

Conventional Cruise Control

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

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

Adaptive Cruise Control (ACC)

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

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

Predictive Cruise Control

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

Cooperative Adaptive Cruise Control (CACC)

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

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

Common Cruise Control Symbols and Indicators

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

Benefits of Using Cruise Control

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

Fuel Efficiency

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

Comfort and Convenience

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

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

Troubleshooting Common Cruise Control Issues

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

Cruise Control and Road Etiquette

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

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

The Future of Cruise Control Technology

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

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

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

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

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

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

Debunking Myths About Cruise Control

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

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

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

Myth : Cruise control increases the risk of accidents.

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

Cruise control is a valuable feature that can enhance your driving experience by providing comfort, convenience, and fuel efficiency. Remember to use it safely and appropriately based on driving conditions, and always stay attentive while on the road.

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 to use cruise control

To use cruise control, you can typically press buttons on your steering wheel to activate the system, set your speed, adjust your speed up or down within the system, and deactivate the system. Using cruise control lets you set a speed for your car to maintain even if you take your foot off the gas. On long trips, it can reduce driver fatigue. Cruise control can also prevent speeding and increase fuel efficiency by limiting unnecessary acceleration and braking.

What is cruise control?

Cruise control is a feature on some vehicles that allows the driver to take their foot off the accelerator while the onboard computer maintains the vehicle’s speed. Within cruise control, you can typically also adjust your speed up and down using buttons.

How does cruise control work?

Modern cruise control is electronic and uses a computer to control your car’s speed. According to Scientific American , cruise control in cars has been around since the early 1900s, but it’s changed over time. Early versions were mechanical, using a second throttle lever mounted to the steering wheel.

Electronic cruise control now comes standard on most cars. Even models that don’t include cruise control on the base model almost always have a car trim level that includes it.

Adaptive cruise control (ACC) is the latest type of cruise control that’s becoming widely available in cars. ACC maintains your speed but incorporates sensors to measure the distance to the car ahead. Once you set a distance, the ACC adjusts your speed to ensure you stay at that distance — usually a car length or two.

According to our report on how car technology impacts safety , adaptive cruise control can be a little confusing for drivers, so learning how to use it correctly is essential.

How to set cruise control

1. check your car’s controls.

If it’s your first time using your car’s cruise control system — or if you’re not 100% sure how to turn on cruise control in your car —the process starts before you crank the engine. Get the car’s manual and learn what each cruise control button does. Different makes and models may have different combinations of buttons or features.

For example, some cars have a combined button to set the initial speed and accelerate. Others have fine-tuning buttons that you can click to increase or decrease your speed by a set amount, often one mph.

2. Evaluate the road

Once familiar with your car’s cruise control system, you can try it out. Wait for a moment when it’s appropriate to use cruise control before turning it on. Check that the road is clear, that weather conditions are good, and that you’re on a highway or a road where you won’t have to stop or change speed often. If conditions are right to use cruise control in your car, turn on the system.

3. Come up to speed

Once the cruise control is active, you’ll need to use your gas or brake pedal to bring the car to the speed you want and then use the “set speed” button to lock in your speed. Make sure your speed is within your area’s established speed limits .

4. Set distance for ACC systems

If you have adaptive cruise control, you may need to set your distance so the system knows how much gap to leave between you and the car ahead of you. Check your owner’s manual for specifics on how your system works. Some manufacturers include three settings, while others can have up to five. If you have ACC, the car will automatically brake and accelerate to keep the correct distance while generally maintaining your set speed when possible.

5. Stay alert

Cruise control isn’t autopilot. While knowing how to use cruise control can reduce leg fatigue, it can require more mental concentration. The car will maintain speed even if road conditions change, so you must carefully pay attention to the road and traffic. When you’re using your car’s cruise control feature, don’t forget your defensive driving skills .

6. Adjust speed as necessary

If you want to speed up or slow down, use the appropriate control. Accelerating with the cruise control system in a car is like using the pedal in terms of acceleration rates and should feel familiar. Slowing down is akin to taking your foot off the gas and won’t slow the car as fast as applying the brake. When decelerating using the cruise control, give yourself adequate time to change speeds or use the brakes to slow down and hit the “set speed” button again.

When to use cruise control

Cruise control is best suited for long drives on large, straight roads such as an interstate highway with cars traveling at a relatively constant speed. It’s inappropriate in stop-and-go traffic; when weather conditions are snowy, icy, or even heavy rain; on narrow, curvy roads; or with frequent speed limit variations. The time and attention it takes to disengage the cruise control in these situations could lead to a crash.

Does cruise control use more gas?

In some cases, it can conserve gas rather than use more gas. Quick acceleration and deceleration change the vehicle’s momentum drastically and wastes fuel. So, using cruise control is most fuel-efficient on level highways and long uphill and downhill grades.

Is there a downside to using cruise control?

One potential downside to using cruise control is that it can result in the driver having a reduced reaction time when they must respond quickly to an unexpected situation on the road. Motorbiscuit reminds drivers that cruise control is not a hands-free driving feature. Distracted driving is a bad driving habit that can lead to crashes, so always stay alert.

Cruise control is one feature you’ll want from a good car for road trips and other frequent highway driving. It can not only potentially help you get better gas mileage but also make driving much more comfortable.

How to use adaptive cruise control.

Difficulty Level: Novice  |   Time Required: 2 Minutes  |   Tools Required: None |  Related Parts, Products, Services or Technology: None

If your vehicle has this available feature, Adaptive Cruise Control † allows you to set a cruise control speed and automatically follow a detected vehicle ahead at a driver-selected following gap. If no vehicle is detected in your path, the feature works like regular cruise control. You can always override the feature and take control.

How to Get Started With Adaptive Cruise Control

1. To turn the feature on, press the cruise control On/Off button on the steering wheel. Your vehicle will default to the type of cruise control you last used when you turned your vehicle off. When the system is turned on, you’ll see a white Adaptive Cruise Control icon in your cluster display or on your Head-Up Display, if your vehicle has that feature. The icon may look like a speedometer with a vehicle on top of it or an arc with a small triangle pointing through it.

a. See “Switching Between Cruise Control Modes” later in this article for more info on switching to the mode you want to use.

2. To choose a cruise speed, press the Set button while driving at the desired speed. The white Adaptive Cruise Control icon will change to green, which means the system is in use.

Setting the Gap

• Select a following gap between your vehicle and the vehicle ahead using the Gap Setting button on the steering wheel. The current gap setting will display briefly on the DIC and Head-Up Display if equipped.
• Each press of the Gap Setting button cycles through Far, Medium or Near gap settings.
• Remember, you’re picking a following gap. That means the following distance will vary based on how fast you’re driving. The more you speed up, the farther back you’ll follow since it would take a greater distance to slow down or come to a stop.
• Select the GAP SETTING that best fits your driving style, the current traffic and the weather conditions.

Auto Set New Speed

• Some newer vehicles are equipped with a feature that detects nearby speed limit signs and can adjust your set Adaptive Cruise Control speed to the newly detected speed limit. Your vehicle must have the available Traffic Sign Recognition feature to use this part of Adaptive Cruise Control.
• When your vehicle detects a new speed limit sign, you’ll see a prompt to change your set Adaptive Cruise Control speed in your DIC. You can choose to accept or deny the suggested speed. Press Resume/+ to accept or Set/- to deny.
• If you don’t do anything, your vehicle will automatically set your Adaptive Cruise Control speed to the detected speed limit.
• You can set an offset to the detected speed limit in case you want your set Adaptive Cruise Control speed to be higher or lower than the detected speed limit. Use the Resume/+ or Set/- buttons to set the offset. Your vehicle will remember the offset when a new speed limit is detected.
• This feature may not work properly if the feature’s camera is obscured or dirty.

Set at Standstill

On properly equipped 2024 model year vehicles, you can set an Adaptive Cruise Control speed while you’re stopped (the system must be on, you must apply the brake pedal and your vehicle must be in a forward gear).

• Press the Set button while your foot is on the brake to turn on the feature.
• You can change the set speed, still with your foot on the brake, by pressing the “+”/resume or “-”/Set button repeatedly until the system shows your desired speed.
• Then, take your foot off the brake, and the vehicle will hold its position. Once traffic moves, press the resume button and the vehicle will automatically accelerate to your set speed or following gap if a vehicle is detected ahead.

Switching Between Cruise Control Modes

On some models, you can switch between Adaptive Cruise Control and cruise control. Here’s how:

• Press and hold the Cancel button.

If you press the accelerator pedal while the system is in use, automatic braking won’t occur. You’ll get a message in the cluster display, or the green Adaptive Cruise Control icon will turn blue, indicating that Adaptive Cruise Control automatic braking is temporarily disabled until you release the accelerator pedal.

You should read your Owner’s Manual to learn more about the limitations of the system.  

Safety Consideration When Using Adaptive Cruise Control

• The system can only brake so much. Your complete attention is always required while driving.
• Adaptive Cruise Control does not steer your vehicle. You must always be in control of vehicle steering.
• The system may not react to parked, stopped or slow-moving vehicles. You should always be ready to take action and apply the brakes.
• Don’t use the system on winding or hilly roads, on freeway exit or entrance ramps, or when trailering (if your vehicle isn’t equipped with Adaptive Cruise Control with trailering). In these driving conditions, the system may not detect the vehicle ahead.
• The system can’t detect traffic lights or traffic signs, so you still need to brake when necessary at intersections and lights.
• Avoid using Adaptive Cruise Control when the rear of the vehicle or truck bed is heavily loaded. See your Vehicle Load Limits and Owner’s Manual for more information.

For your security, please don’t include personal info such as phone number, address or credit card details.

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.

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.

Carnival Cruise Line answers bed bug 'infestation' accusation

B ed bugs are a menace because once you have them, they spread quickly. Even when incidents are minor and well-contained, the publicity is bad because nobody wants to risk bringing the pesky critters home.

That's why multiple reports of bed bugs on the Las Vegas Strip led to a wave of bad press, even though the casino operators that had the incidents actually did a really good job controlling the problem.  

Related: Carnival Cruise Line makes major main dining room menu change

In the case of the Las Vegas bed bug incidents, it was four reported cases over three months where each hotel had a single case. That makes it very likely that the bed bugs came with the traveler rather than the hotel.

But, even a single bed bug is a bit like someone having a coughing fit on a cruise ship. The person coughing may know that they swallowed a pretzel that's scratching their throat, but any nearby passengers assume Covid, the flu, or norovirus. 

Bed bugs on a cruise ship would be a significant problem because cabins are very tightly spaced and people are generally in close quarters. Just like the very rare cases where norovirus has spread on a cruise ship, the problem can go from an isolated incident to infestation very quickly. 

Like bed bugs, however, rumors spread very quickly. That's why Carnival Brand Ambassador John Heald addressed some concerns he has seen on various message boards and social media sites.

Bed bugs are everywhere

 Bed bugs are a global problem, according to the Centers for Disease Control (CDC).

"Bed bugs are in five-star hotels and resorts. How clean a place is does not determine whether bed bugs are present," the federal agency shared.

Bed bugs, based on their long, flat shape, are very good at hiding, and they can go long periods without feeding on blood (like a sort of mini-vampire.

"Bed bugs bite people and animals at night while they sleep, feeding on their blood....Bed bugs are not known to spread diseases to people. However, they cause irritation, itching, and loss of sleep," the CDC added.

In rare cases, when people are allergic, more serious reactions can occur.

Carnival tries to shut down passenger concerns

"There's very few things that get my hair itchy. One of those is when people post things, never on my page, but on other pages, that are simply not true," Heald shared in a Facebook video.

When a false post goes up, Heald noted that he gets hundreds of emails and Facebook messages asking if the news is true.

"Some of you write to me and say, it's disgusting, how do you let this happen? One of those things that I'm talking about is how someone posted about something that was allegedly on one of the ships," he shared.

Heald declined to share the name of the ship in question.

"Apparently, according to this person, the ship had, and I quote, 'an infestation of bed bugs and 150 of you wrote to me saying 'is it true?' and 'Why aren't we doing anything," he continued. 

Heald shared that none of the messages came from people actually on the ship in question saying that they had a problem.

"Before I say anything, let me say this, we have protocols in place, the strictest protocols. If anybody makes an allegation, our brilliant housekeeping staff, our public health officers, do what they do, and nine times out of 10 nothing is found and there is no problem," he explained. "If there is, we have protocols in place to take care of it immediately."

In this case, that's not what happened.

"Somebody alleged on another cruise Facebook page that on the ship they were on was, and I quote, 'infested with bed bugs," Heald added.

The brand ambassador explained that he wrote to the hotel director who shared three things with him.

"Number one, there is no guest of that name currently nor has there ever been on that ship. Secondly, here is what the hotel director wrote to me 'We do not have any issues with bed bugs onboard,'' he shared. 

The hotel director also shared that the pictures that were part of the post were not taken on a Carnival ship. 

"It's my job to set the record straight," Heald added. "Please, take a look, think, before you me, or anybody of this kind of thing happening."

How to use adaptive cruise control.

Difficulty Level: Novice  |   Time Required: 2 Minutes  |   Tools Required: None  |  Related Parts, Products, Services or Technology: None

If your vehicle has this available feature, Adaptive Cruise Control †  allows you to set a cruise control speed and automatically follow a detected vehicle ahead at a driver-selected following gap. If no vehicle is detected in your path, the feature works like regular cruise control. You can always override the feature and take control.

How to Get Started With Adaptive Cruise Control

1. To turn the feature on, press the cruise control On/Off button on the steering wheel. Your vehicle will default to the type of cruise control you last used when you turned your vehicle off. When the system is turned on, you’ll see a white Adaptive Cruise Control icon in your cluster display or on your Head-Up Display, if your vehicle has that feature. The icon may look like a speedometer with a vehicle on top of it or an arc with a small triangle pointing through it.

a. See “Switching Between Cruise Control Modes” later in this article for more info on switching to the mode you want to use.

2. To choose a cruise speed, press the Set button while driving at the desired speed. The white Adaptive Cruise Control icon will change to green, which means the system is in use.

Setting the Gap

1. Select a following gap between your vehicle and the vehicle ahead using the Gap Setting button on the steering wheel. The current gap setting will display briefly on the DIC and Head-Up Display if equipped.

2. Each press of the Gap Setting button cycles through Far, Medium or Near gap settings. 3. Remember, you’re picking a following gap. That means the following distance will vary based on how fast you’re driving. The more you speed up, the farther back you’ll follow since it would take a greater distance to slow down or come to a stop. 4. Select the GAP SETTING that best fits your driving style, the current traffic and the weather conditions.

Auto Set New Speed

1. Some newer vehicles are equipped with a feature that detects nearby speed limit signs and can adjust your set Adaptive Cruise Control speed to the newly detected speed limit. Your vehicle must have the available Traffic Sign Recognition feature to use this part of Adaptive Cruise Control.

2. When your vehicle detects a new speed limit sign, you’ll see a prompt to change your set Adaptive Cruise Control speed in your DIC. You can choose to accept or deny the suggested speed. Press Resume/+ to accept or Set/- to deny.

3. If you don’t do anything, your vehicle will automatically set your Adaptive Cruise Control speed to the detected speed limit.

4. You can set an offset to the detected speed limit in case you want your set Adaptive Cruise Control speed to be higher or lower than the detected speed limit. Use the Resume/+ or Set/- buttons to set the offset. Your vehicle will remember the offset when a new speed limit is detected.

5. This feature may not work properly if the feature’s camera is obscured or dirty.

Set at Standstill

On properly equipped 2024 model year vehicles, you can set an Adaptive Cruise Control speed while you’re stopped (the system must be on, you must apply the brake pedal and your vehicle must be in a forward gear).

1. Press the Set button while your foot is on the brake to turn on the feature.

2. You can change the set speed, still with your foot on the brake, by pressing the “+”/resume or “-”/Set button repeatedly until the system shows your desired speed.

3. Then, take your foot off the brake, and the vehicle will hold its position. Once traffic moves, press the resume button and the vehicle will automatically accelerate to your set speed or following gap if a vehicle is detected ahead.

Switching Between Cruise Control Modes

On some models, you can switch between Adaptive Cruise Control and cruise control. Here’s how:

1. Press and hold the Cancel button.

2. After a brief time, the icon in the cluster will switch modes. You can then let go of the button.

3. You’ll see a message in your cluster display that you have switched between cruise control and Adaptive Cruise Control. Then, check which cruise control icon is displayed before you set the cruise control speed and start using the system.

4. Pressing and holding the Cancel button will switch between cruise control modes.

CRUISE CONTROL

ADAPTIVE CRUISE CONTROL

Canceling Adaptive Cruise Control

If you want to stop using Adaptive Cruise Control, you can:

• Tap the brake pedal
• Press the Cancel button
• Press the cruise control On/Off button

Adaptive Cruise Control Override

If you press the accelerator pedal while the system is in use, automatic braking won’t occur. You’ll get a message in the cluster display, or the green Adaptive Cruise Control icon will turn blue, indicating that Adaptive Cruise Control automatic braking is temporarily disabled until you release the accelerator pedal.

You should read your Owner’s Manual to learn more about the limitations of the system.

Safety Consideration When Using Adaptive Cruise Control

• The system can only brake so much. Your complete attention is always required while driving.
• Adaptive Cruise Control does not steer your vehicle. You must always be in control of vehicle steering.
• The system may not react to parked, stopped or slow-moving vehicles. You should always be ready to take action and apply the brakes.
• Don’t use the system on winding or hilly roads, on freeway exit or entrance ramps, or when trailering (if your vehicle isn’t equipped with Adaptive Cruise Control with trailering). In these driving conditions, the system may not detect the vehicle ahead.
• The system can’t detect traffic lights or traffic signs, so you still need to brake when necessary at intersections and lights.
• Avoid using Adaptive Cruise Control when the rear of the vehicle or truck bed is heavily loaded. See your Vehicle Load Limits and Owner’s Manual for more information.

For your security, please don't include personal info such as phone number, address or credit card details.

RELATED LINKS AND RESOURCES

About adaptive cruise control, troubleshooting adaptive cruise control, do i need to keep the camera and radar sensors, if equipped, clean.

Yes. It’s important to keep the windshield clean for the camera to work properly and to keep the front grille and bumpers clean for the radar sensors, if equipped, to work properly. Read your Owner’s Manual for cleaning instructions.

WHAT CAN CAUSE ADAPTIVE CRUISE CONTROL TO NOT PERFORM AS EXPECTED?

Bad weather that affects road surface traction or visibility may impact its performance. Also, if the forward-looking camera or radar sensors, if equipped, are obstructed in any way, the system will not perform as expected. Adaptive Cruise Control systems may not perform as expected where lighting is poor or when following vehicles with unusual shapes.
