Adaptive cruise control?

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

What does adaptive cruise control do?

Adaptive cruise control (ACC) is an enhancement of conventional cruise control. ACC automatically adjusts the speed of your car to match the speed of the car in front of you. If the car ahead slows down, ACC can automatically match it.

Will adaptive cruise control stop the car?

Adaptive cruise control can increase or decrease your car’s speed to maintain a following distance that you set. Advanced versions can even slow and stop your car in traffic jams, then accelerate for you.

When should you use adaptive cruise control?

Adaptive cruise control basics ACC is ideal for stop-and-go traffic and rush hour commuting that swings from 60 mph to a standstill.

Is adaptive cruise control Safe?

Is adaptive cruise control safe to use? In short, yes, adaptive cruise control is perfectly safe to use. However, before using any self-driving technology, it’s important to understand your car’s system and remember that systems differ between makes.

Is cruise control bad for your car?

Is cruise control bad for your car? Absolutely not. Acceleration that costs fuel also causes wear and tear on the driveline, so cruise control is good for the car.

Can I put cruise control in my car?

You can easily add aftermarket cruise control kits to your vehicle and they are easy to install. Ability to increase gas mileage because of the vehicle’s consistent speed.

Can you use adaptive cruise control in the rain?

Myth: Cruise control can be used all the time regardless of driving weather. Fact: Using cruise control when driving in the rain, snow, hail, sleet or ice, slippery roads can affect the system’s ability to maintain a constant vehicle speed. Drive safe and avoid using cruise control on slippery roads.

Does cruise control use brakes?

Because cruise control usually just relies on the throttle to control speed and not the brakes, there’s very little way the system can do to prevent the car from ‘running away’ down a hill.

Is it bad to use cruise control at low speeds?

High Traffic Conditions – cruise control is not suited for low speeds, making it not suited for slow-moving traffic. When the road conditions require you to start and stop, such as heavy traffic, cruise control may cause you to rear-end another vehicle.

Does cruise control use more fuel?

Generally speaking, yes. Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.

Do brake lights come on when using adaptive cruise control?

ACC (Adaptive Cruise Control) will apply the brakes when exceeding the setpoint from going downhill and the brake lights will come on. If the car slows down using engine compression, the brake lights will not come on.

What is the minimum speed for cruise control?

Cruise control should not work on speeds under 25 mph or 40 kph. This is because cruise control is intended for use on highways where traffic is usually less congested than city driving and is a feature that enables the driver to relax on longer trips and also maintain a steady speed.

How much does adaptive cruise control cost?

If you’re going to have an ACC with all available features, you should be willing to pay anywhere between $2000 and $2500. If you are looking for minimal cruise control that would benefit speeds of up to 20-25 miles per hour, these more basic ACCs can cost as low as $500.

Does adaptive cruise control work in stop and go traffic?

Adaptive Cruise Control (ACC)12 maintains speed and the following interval to the vehicle detected ahead. And the low-speed follow feature helps make it easier to drive in stop-and-go traffic. The Feature: When the preceding detected vehicle slows to a stop, ACC can stop the Accord automatically.

What Is Adaptive Cruise Control?

Automatic cruise control (ACC) is a device that assists drivers in maintaining a safe following distance while maintaining a speed that is within the speed limit. This system automatically adjusts the speed of a vehicle so that drivers are not required to do so.Adaptive cruise control is one of 20 terms used to describe its functions, and you may see adaptive cruise control described as follows in advertisements and vehicle descriptions: adaptive cruise control

  • Active cruise control, dynamic cruise control, radar cruise control, automatic cruise control, and intelligent cruise control are all terms used to describe various types of cruise control.

Active cruise control, dynamic cruise control, radar cruise control, automatic cruise control, and intelligent cruise control are all terms that are used to describe various types of cruise control technology.

Advantages of Adaptive Cruise Control

Some of the most significant benefits of adaptive cruise control, according to, include an increase in road safety, since automobiles equipped with this technology will maintain an appropriate distance between themselves and other vehicles. These space-aware capabilities will also aid in the prevention of accidents that may occur as a consequence of obscured vision or a close following distance. Similarly, due of its spatial awareness, ACC will aid in the optimization of traffic flow.

Limitations of Adaptive Cruise Control

Aside from the numerous benefits of adaptive cruise control, drivers need be aware of the restrictions of this technology as well. One of the most significant shortcomings of this system is that it is not completely independent. The driver of the car must continue to adopt safe driving practices that will operate in conjunction with the technology in order to achieve the greatest possible outcomes from it. In a similar vein, poor weather conditions such as snow, rain, or fog, as well as environmental variables such as driving through tunnels, might cause the system’s sensors to malfunction.

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

In accordance with SAE International, when a car merely has autonomous cruise control, it is classified as a level 1 autonomous vehicle. A vehicle with autonomous cruise control plus an extra function, such as lane control, on the other hand, is designated as a level 2 autonomous vehicle.

How Much Does an Adaptive Cruise Control System Cost?

In accordance with ExtremeTech, the cost of an adaptive cruise control system will vary based on the number of functions you wish to include. An ACC with all of the features you want should cost between $2000 and $2500 if you want to get the most out of it. For those searching for the most basic cruise control that would benefit speeds of up to 20-25 miles per hour, these less expensive ACCs may be purchased for as little as $500. The good news is that when ACC becomes more widely available, its cost will almost certainly decrease.

History of Adaptive Cruise Control

According to U.S. News, Mitsubishi was the first company to deploy adaptive cruise control in Japan in 1992. This was a lidar-based distance detecting system that alerted the user when an item was approaching too closely. It was given the name ‘Debonair,’ and it was designed to alert the driver when an item was approaching from behind. The most significant distinction was that it was the driver’s responsibility to apply the brakes and slow down their vehicle. However, two years later, in 1995, the Mitsubishi Diamante introduced a new approach to the Debonair known as ‘Preview Distance Control,’ which was an improvement over the previous model.

The driver was still in charge of deploying the brakes as necessary.

These distinct characteristics have combined to form a high-tech system that includes autonomous braking and speed control.

Types of Adaptive Cruise Control

According to eInfoChips, radar-based systems function by mounting radar-based sensors on or around the plastic fascias of vehicles in order to monitor the environment around the vehicle. When all of the radar sensors are working together, a full image of the vehicle’s proximity to other vehicles or potentially dangerous objects is created. Depending on the design and model of the vehicle, this sort of sensor may have a distinct appearance.

Laser-Based Systems

Like the sort of ACC system described by Electronic Design, this type of system is housed in a huge black box that is often located in the grille of your car. It makes use of laser technology to identify items that are in close proximity to your vehicle. The device does not perform effectively during rainstorms or other adverse weather conditions.

Binocular Computer Vision Systems (Optical)

It was only in 2013 that ExtremeTech discovered and implemented this relatively new ACC system. It works by using tiny cameras that are mounted on the back of a car’s rearview mirror to detect things in front of the vehicle.

Assisting Systems

Assisting systems are radar-based add-ons that clients may purchase in a package with their vehicle. They can provide lane control, braking assistance, cruise control, proximity alerts to objects such as corners, and steering power to drivers before a collision occurs.

Multi-Sensor Systems

To help in the operation of a car, according to Fierce Electronics, adaptive cruise control systems may incorporate more than one type of sensor to aid in the operation of the vehicle. Advanced information is provided to drivers by multi-sensor systems, which include multiple different sensor types. GPS data technology and cameras are examples of sensors that may be used to acquire information about a vehicle’s geographic surroundings and its proximity to other vehicles.

Predictive Systems

Prediction systems, as described by Autoblog, are a sort of ACC that uses sensory data to forecast the behaviors of cars in the immediate vicinity of the driver. This implies that your vehicle may need to slow down in order to prepare for a vehicle abruptly changing lanes, which increases passenger safety by decreasing driver distraction. Adaptive cruise control is becoming more sophisticated with each passing year. Automobile manufacturers are constantly refining this technology, resulting in more common and cheap choices that can be purchased with a new car or retrofitted onto older ones, therefore making driving safer for the general population.

What Is Adaptive Cruise Control?

The most cutting-edge luxury car innovations of today are frequently adopted by conventional automobiles in the future.

Take, for example, cruise control, which is now standard on practically every new car, with the exception of specialized performance variants and base trims of entry-level vehicles. But, exactly, what is adaptive cruise control (ACC)? And is it worth your time to use it?

How Adaptive Cruise Control Works (and Its Limitations)

When used in conjunction with non-adaptive systems, adaptive cruise control can maintain a desired speed on the highway while providing added convenience. That alone helps to ease the tension of lengthy road journeys by reducing the amount of time spent pressing the accelerator pedal. This convenience is enhanced even further by adaptive cruise control, which allows the driver to choose a preferred speed and following distance from any vehicles that may be ahead of them. A slower vehicle moves in front of you, and the system automatically slows to maintain the pre-defined following distance before accelerating back to the original set speed after the car has moved out of the way.

It is true that adaptive cruise control has its limitations, just like any other safety or convenience technology.

Furthermore, if the vehicle in front of you brakes quickly, you will very certainly be required to intercede.

Weather and debris can have a negative impact on adaptive cruise control, which depends on radar and/or video sensors to identify cars in front of the vehicle.

How Can Adaptive Cruise Control Make My Commute Easier?

When driving in a variety of cruising circumstances, the most basic adaptive cruise control systems ease the tension of having to constantly press the accelerator pedal. Stop-and-go feature, often known as traffic jam assist, is available on the more recent and better systems. This enables the car to easily maintain low speeds while utilizing adaptive cruise control, due to the system’s capacity to come to a complete stop when traffic in front of it does as well. Many systems will deactivate after a few seconds of inactivity, necessitating the use of the resume button or the accelerator pedal in order to get them back up and running.

For the most stress-relieving travel, the latest and greatest systems combine additional driver aid technologies like as lane keeping assist, front collision warning, pedestrian recognition, and automated emergency braking to deliver the maximum level of stress reduction possible.

The addition of an adaptive cruise control (ACC) technology allows the car to maintain its position in a single lane and navigate mild curves, substantially decreasing the stress of your commute or road trip.

Some automakers have also included a lane change assist feature in their vehicles. These work by scanning the next lane for traffic when you use the turn signal, and if it is safe, the sensors guide the car over and center it in the next lane, as opposed to traditional turn signals.

What to Look for in a Vehicle With Adaptive Cruise Control

  • Check to see whether your adaptive cruise control includes a stop-and-go feature (also known as traffic jam assist). This characteristic ensures that it can continue to operate even when highway traffic slows to a crawl
  • Yet, When a car drives in front of you or out of your lane, pay attention to how smoothly the car accelerates and stops on its own, and how smoothly the car accelerates and brakes on its own. Some systems, such as those found on Audis and Subarus, let you to customize the aggressiveness of the technology. Using highway and lower-speed driving, measure the distance the automobile travels while it is at its closest adaptive cruise control setting. Has the distance found a happy medium between being an acceptable distance and not being so far back that drivers cut in front of you all the time. Is it possible to switch between conventional and adaptive cruise control? A non-adaptive option is available in some driving conditions where an adaptive system’s frequent braking and resuming can be less comfortable than normal cruise control. Having a non-adaptive option also allows cruise control to continue to function in the event that the sensors become temporarily obscured.

Which Automakers Have Excellent Adaptive Cruise Control Systems?

Not all adaptive cruise control systems are worth your time and effort to experiment with. Exceptional systems are available from Subaru, BMW, Honda, Nissan, Hyundai, Kia, and Ford, all of which perform smoothly and consistently, even while driving in stop-and-go traffic. All of these measures are intended to reduce the stress associated with driving, particularly for people who have long journeys through congested metropolitan areas.

Is Adaptive Cruise Control Worth It?

It is possible that adaptive cruise control will make a significant difference in your commute if you have a long commute and believe that you can learn to trust the technology (while constantly paying attention and being ready to take over promptly if required). It is possible to reduce a significant amount of stress connected with driving by allowing your automobile to operate the accelerator and brakes for most of your commute to and from work. The converse is true as well: if a system is developed with driving logic that bites the brakes too hard as it comes to a stop or permits too much distance at its closest setting, you may find yourself utilizing the technology only once and never again for the remainder of your time with the vehicle.

What Do Automakers Call Adaptive Cruise Control?

Toyota and Lexus: Dynamic Cruise Control, Dynamic Cruise Control with Stop and Go, Dynamic Cruise Control with Stop and Go Intelligent Cruise Control is available on Nissan and Infiniti vehicles. Hyundai: Intelligent Cruise Control Kia: Smart Cruise Control with Advanced Technology Honda and Acura: Adaptive Cruise Control, Adaptive Cruise Control with Low-Speed Follow, Adaptive Cruise Control with Low-Speed Follow Subaru:Adaptive Cruise Control, Adaptive Cruise Control with Lane Centering, Adaptive Cruise Control with Lane Departure Warning Mercedes-Benz: Distronic Active Distance Assist (ADAS).

The following BMW features are available: Active Cruise Control, Active Cruise Control with Stop and Go.

Adaptive Cruise Control:

Not only does it keep your set speed constant, but it also keeps your following distance constant; it also provides some restricted braking. What It Does:It automatically accelerates and decelerates your vehicle to maintain a certain following distance relative to the vehicle in front of you. Provides a small amount of braking. What It Does Not Do:You must understand how much braking the system is capable of providing—some systems will brake to a complete stop, while others will only brake to a certain point.

Take a look at this video.

Quick Guide

Select the required speed from the drop-down menu.

2. Set Gap

Configure your desired following distance, also known as the gap; if the gap changes, ACC slows or speeds up to maintain the specified distance.

3. Stay Focused

Always keep an eye out for other vehicles in your vicinity.

How it works

In order to maintain the following distance that you specify, adaptive cruise control might raise or decrease your vehicle’s speed. Some of the more advanced models may even slow and halt your automobile in traffic jams before accelerating for you.


In order to maintain a certain following distance, adaptive cruise control might raise or decrease your vehicle’s speed.

Advanced versions can even slow and halt your automobile in traffic jams, then accelerate for you. They also include more features.


Accelerate to the desired speed and then switch on the ACC system. You tell the ACC how close you want your following distance gap to be (usually, short, medium, and long distances), and it’s ready to start operating immediately after that. You should, however, be vigilant and mindful of your surroundings. It is not recommended to employ ACC in inclement weather or other potentially hazardous driving circumstances. More information may be found in your vehicle’s owner’s handbook.

  • Keep take mind that ACC may not function properly in some sorts of weather situations. Heavy fog or rain, dirt, snow, or ice covering the sensors, or slick streets are just a few instances of what may happen in these situations. These systems may also be ineffective in tunnels
  • ACC, on the other hand, helps you to conserve energy by maintaining a closer following distance with the vehicles in front of you. You should take advantage of this chance to pay closer attention to the traffic mix, which includes automobiles ahead of you and in neighboring lanes. Check your owner’s handbook to check if your ACC is capable of bringing your vehicle to a complete stop, or if you must come to a complete stop on your own initiative.


In addition to the names listed above, this feature may be sold under the following names:

  • Automatic cruise control, active cruise control, cooperative adaptive cruise control, intelligent cruise control, and radar cruise control are all terms used to describe cruise control.

The following distance options in most automobile companies’ implementations of ACC are comparable, with options such as “short, medium, and long” being available. Some cars can even provide a choice between four or five different following distances. More information on what each of the following distance settings signifies may be found in your owner’s handbook. Each manufacturer’s version of ACC operates by the use of one or more sensors, ranging from radar to camera sensors. Heavy fog or rain, as well as dirt, snow, or ice covering the sensors, as well as slippery situations, are all instances of severe weather that might have an impact on these sensors.

While most types of adaptive cruise control (ACC) that have been released to the market are capable of slowing down your automobile when the car in front of you slows, doing so will need you applying additional brake pressure.

A feature of certain newer versions of ACC is the ability to automatically shut down your vehicle and then start it back up again.

What is Adaptive Cruise Control?

When you’ve gotten out of the city and reached a length of somewhat wide road, you may put on the cruise control, select a speed, and take a little rest with your right foot while the car maintains the pace you’ve chosen for yourself.

Many modern automobiles now are equipped with adaptive cruise control, which allows them to go even further (ACC). There are several names for adaptive cruise control (ACC), including Dynamic Cruise Control, Intelligent Cruise Control, and Active Cruise Control, but they all serve the same purpose.

How Does Adaptive Cruise Control Work?

In order to compute your surroundings, adaptive cruise control employs a variety of sensors including radar, lasers, cameras, or a combination of any of these. This system uses sensors and computers to evaluate what the automobile in front of you is doing and manage your car in relation to that car in order to maintain a safe distance, braking when they slow down and accelerating when they accelerate, up to the predetermined maximum distance. Eventually, LiDAR (Light Detection and Ranging), which is a pulsed laser that can be used to produce a more thorough 3D “map” of the car’s surrounds, will also be used to assess the car’s surroundings, however no automobile in the United States is currently equipped with LiDAR technology.

Various Types of ACC

Adaptive cruise control is available in a variety of levels of autonomy and sophistication, with the majority of applications involving driving at lower speeds in congested traffic.

  • Some cars, such as the 2021 Ford F-Series Super Duty, will only function well at comparatively higher speeds
  • Once the vehicle goes down to a specific speed, the ACC system will switch itself off, at which point the driver will be required to take over control of the vehicle. It is the driver’s responsibility to bring the vehicle to a complete stop, and this form of ACC will provide warning noises and lights on the dashboard to remind them of their responsibilities. Other types of ACC will bring the car to a complete stop but then switch itself off. Once traffic resumes its normal flow, you must reactivate the system in order for it to reengage. This sort of ACC is included in the 2021 Jeep Wrangler
  • The most modern systems are equipped with Stop and Go functionalities, which allow the system to completely stop the vehicle before reengaging itself. Some systems allow you to halt for a few seconds before disengaging, while others let you to stop for up to 30 seconds before disengaging.

ACC Paired with Other Capabilities

The combination of ACC systems with technologies such as road sign recognition or GPS navigation allows certain manufacturers to inform drivers of the speed limit on the road they are currently traveling on and to self-regulate to ensure that they do not exceed it. The speed of the vehicle will be automatically adjusted to account for bends in the road or the turn to enter a freeway interchange, among other things. Additionally, ACC may be used in conjunction with lane-centering technology to provide a more automated driving experience, such as with Hyundai’sHighway Driving Assist, or even hands-free driving on designated highways for limited periods of time.


Drivers who use adaptive cruise control must maintain complete concentration on the road and be prepared to take over at any time. It is possible that cars may be developed that will allow drivers to divert their attention for small periods of time, but none are currently available for purchase in the United States at the time of this writing.

What is Adaptive Cruise Control?

When a car is in adaptive cruise control mode, the vehicle’s acceleration and braking are controlled automatically. The operation of adaptive cruise control When driving, adaptive cruise control keeps an eye out for other cars and roadside items, allowing for a more pleasant and safe driving experience. It accomplishes this by assisting the driver in maintaining a constant vehicle speed at any given time. The driver can choose their preferences for a variety of aspects, including the distance between their vehicle and the vehicle in front of them, the driving style (for example, economical, sporty, or pleasant), and others.

  • Cruise control has gone a long way since its inception as a means of assisting drivers on the road, and it continues to improve.
  • As more affordable sensors become available on the market, adaptive cruise control is gradually becoming a regular function in new automobiles on the road today.
  • The speedostat, which was designed by Ralph Teetor in 1948, is credited with the invention of conventional cruise control.
  • On a highway with no traffic, one example is the automated pushing of the acceleration pedal, which allows drivers to remove their foot off the accelerator for a few minutes while still maintaining control of the vehicle.
  • Towards the end of the 1990s, various automobile manufacturers began offering a new version of cruise control, known as adaptive cruise control.
  • Because automation enabled the cruise control function to regulate both the acceleration and braking of a vehicle, this enhancement considerably increased the amount of time the cruise control function could be used continuously.
  • Of course, they still had to pay attention to the road ahead of them, because automobiles in front of them may still stop or abruptly cut in front of them.

As a result, there is increased pressure for it to be enhanced further. In response to recent advancements in ACC, the industry is changing to a new standard in the category known as intelligent cruise control.

Adaptive cruise control for passenger cars

In most cases, a radar sensor is at the heart of the adaptive cruise control system (ACC). The device, which is installed at the front of the car, is constantly monitoring the road ahead. For as long as there is no obstruction in front of the vehicle, the ACC maintains the speed selected by the driver. If the system detects a slower vehicle within its detecting range, it softly slows speed by releasing the accelerator pedal or aggressively engaging the brake control system, depending on the circumstances.

  • Driver assistance systems, such as standard ACC, can be engaged from speeds of roughly 30 km/h (20 mph) and can assist the driver, mainly on long-distance or interstate excursions.
  • It has the ability to maintain the predetermined space between itself and the preceding vehicle even at extremely low speeds and can decelerate to a complete stop.
  • When the car is stopped for an extended period of time, the driver merely needs to reactivate the system, for example, by momentarily depressing the gas pedal to revert to ACC mode, to make it operational again.
  • Because the ACC system is designed to provide comfort and convenience, brake interventions and vehicle acceleration are only permitted within certain parameters.
  • It is possible to install a multi-purpose camera in addition to the radar sensor in order to improve the comfort and safety of this function.
  • In order to gain a more complete and reliable picture of the situation, data from the radar sensor and camera can be combined.

What is adaptive cruise control, and how does it work?

It is possible that this site will get affiliate commissions from the links on this page. Terms and conditions of usage. When it comes to vehicles, we at ExtremeTech consider them to be much more than simply four wheels, an engine, and a couple of seats. Cars are the ultimate mobile technology platform, and we consider them to be as important as the latest processor or smartphone in terms of attracting our attention.

With this in mind, we’ll be launching a series of basic car technology articles that will provide readers with in-depth explanations of today’s most essential technologies in the coming months. The series begins with adaptive cruise control, which is the first of its kind.

Adaptive cruise control basics

Adaptive cruise control (ACC) is a sophisticated kind of cruise control that automatically slows down and speeds up to keep up with the vehicle in front of you. A radar sensor checks for traffic ahead, latches on to the car in a lane, and orders the car to maintain a distance of 2, 3, or 4 seconds behind the vehicle in front of it, exactly like with cruise control (the driver sets the follow distance, within reason). ACC is now almost always used in conjunction with a pre-crash system that informs you and, in many cases, initiates braking.

  • As of 2013, the cost of adaptive cruise control ranges from $2,500 at the high end to as little as $500 at the low end.
  • For full-range adaptive cruse control, expect to pay $2,000-$2,500, though the price is expected to come down in the near future.
  • Active cruise control, autonomous cruise control, intelligent cruise control, and radar cruise control are all terms used to describe adaptive cruise control.
  • A laser is used in certain units; however, a stereoscopic camera system is used by Subaru in its optical system.
  • Autonomous vehicle control (ACC) is an essential component of the self-driving automobiles of the near future.
  • Adaptive cruise control is generally used in conjunction with a front collision warning system that operates even if the driver does not have adaptive cruise control turned on.

(There is also driver and passenger discomfort as a result of the autonomous braking system.) Red lights flash in the direction of the driver (as in the case of the Ford Taurus depicted above), the words “Brake!” or “Brake Now!” appear on the instrument panel or head-up display, and a loud chime is heard.

Using ACC

To begin using adaptive cruise control, proceed in the same manner as you would with conventional cruise control. The driver activates the adaptive cruise control (ACC), accelerates to the desired speed, and then hits the “Set” button. It is then possible to adjust the speed by using the “+” and “-” buttons, which commonly raise or reduce the speed by 1 or 5 mph increments. Finally, the driver may select the appropriate following distance behind the next vehicle, which is often accomplished by clicking a button to cycle among short, medium, and long following distance options.

While some manufacturers, such as Mercedes-Benz, display the following distance in feet, in reality it is measured in seconds of following gap converted to feet — for example, 200 feet of following distance at 60 mph (88 feet per second) is around 3 seconds.

When radar detects a vehicle ahead, either a second car icon emerges or the color of the lone vehicle icon changes.

If you select the closest following distance, you’ll become anxious if the following distance appears to be getting dangerously near and you’re not sure if the automatic collision avoidance system (ACC) is functioning properly.

Most likely, it is operational, and the driver may have accidentally softly touched the brake pedal while driving and not realized it, resulting in ACC being available but not activated. The next page will discuss the technology that underpins adaptive cruise control.

What is adaptive cruise control?

Starting from the same point as when using conventional cruise control, adaptive cruise control is activated. Turning on the adaptive cruise control, accelerating to the desired speed, and pressing the “Set” button are all steps in the process. It is then possible to adjust the speed by pressing the “+” and “-” keys in increments of one or five miles per hour. Finally, the driver may select the appropriate following distance behind the next vehicle, which is often accomplished by pushing a button to cycle among short, medium, and long following distance settings.

Adaptive cruise control*

The adaptive cruise control (ACCAdaptive Cruise Control) assists the driver in maintaining a constant speed in conjunction with a pre-determined time interval to the car in front of them. When driving long distances on motorways or long straight major highways with steady traffic flows, adaptive cruise control may make the ride more peaceful and enjoyable. The distance between the car in front and the camera and radar unit is measured. The driver determines the desired speed as well as the time interval between the car in front of him.

When the road is clear again, the automobile resumes to the speed that was previously set for it.


  • The feature is supplemental driver assistance designed to make driving easier and safer
  • Nevertheless, it is not capable of dealing with all scenarios in all traffic, weather, and road conditions
  • And To understand about issues such as its limits and what the driver should be aware of before using the system, it is recommended that the driver study all portions of the Owner’s Manual that pertain to this function. Driver assistance features are not intended to take the place of the driver’s attention and judgment. In all cases, the driver is responsible for ensuring that the vehicle is operated in a safe manner, at the proper speed, with an acceptable space between it and other vehicles, and in line with current traffic laws.

Acceleration and braking are used to adjust the speed of the vehicle using adaptive cruise control. When the brakes are applied to change the vehicle’s speed, it is usual for a low sound to be heard. The adaptive cruise control is designed to maintain a smooth speed control setting. When faced with a scenario that necessitates sudden braking, the driver must brake himself or herself. This is true in situations when there are significant speed disparities or when the car in front brakes quickly.

The adaptive cruise control attempts to keep up with the car in front of it in the same lane at a speed determined by the driver.

If the radar unit does not detect any vehicles in front of the vehicle, the automobile will instead maintain the speed that the driver has chosen and saved. This can also happen if the speed of the car in front of you increases and surpasses the speed that has been set.


Maintenance on driver support components can only be done in a workshop, and it is suggested that you choose a Volvo-certified shop.

What is cruise control and adaptive cruise control?

Once you understand how cruise control works, it is a highly safe function to have on your new car in the United Kingdom. As with many driver-aid systems, it is quite safe to use once you understand how it works. Because it allows you to relax your right foot when driving on the highway, it is popular with motorway drivers. It can even assist drivers escape penalties for speeding, particularly in situations such as average-speed checkpoints. Cruise control is available in a wide range of automobiles, including those with manual transmissions.

Although cruise control was first introduced in the United States more than seven decades ago, it has just become widely used in the United Kingdom in the last few decades.

If you’ve never used a cruise-control system before, it might be a bit intimidating.

Some devices will also not operate if the vehicle is traveling below a specific speed, generally 20mph.

How does cruise control work?

Cruise control allows you to drive at a preset speed that you specify. The usage of this technique is especially beneficial on lengthy road drives since it allows you to relax your right foot rather than maintaining it in the same position for extended periods of time. The controls connected with cruise control are frequently situated on the steering wheel or on a column stalk in order to be accessible as conveniently and safely as possible by the driver and passengers. No of how a particular system is designed to operate, applying the brake pedal will immediately override any cruise-control system, which is necessary for safety.

  • Turning it on is usually always followed by the illumination of a dashboard light.
  • In most automobiles, this will result in the dashboard indicator becoming green.
  • The cruise control should still remember the speed you set it to when you first turned on the car.
  • If you drive a manual automobile, you’ll still have to shift gears manually if the situation calls for it.
  • When you have cruise control turned on, use the up and down arrows (or the ‘+’ and ‘-‘ keys) to increase or decrease the vehicle’s speed.

Single pushes often raise or decrease the speed in small amounts, however holding the same button or stalk for an extended period of time adjusts the speed in increments of 5mph or more. It goes without saying that this varies from one model to the next.

Can cruise control save me money?

However, while cruise control’s primary function is to alleviate tension while driving, it’s likely that by smoothing out acceleration and deceleration, it can also help you save money on gas as well. Some experts, on the other hand, say that these systems are not very fuel efficient on inclines and descents, resulting in savings that are so minor that you will likely not notice them. The primary reason why motorists might experience a cost savings is because cruise control helps them maintain a consistent speed that is fuel-efficient.

What is a speed limiter?

Some automobiles are equipped with a speed restriction, which may be used in conjunction with cruise control or on its own. You may choose the maximum speed you’d want to drive at, much as with cruise control, but unlike cruise control, you’ll still need to press the accelerator to get to that pace. This is particularly useful in high-traffic speed-limit zones, where you may wish to keep complete control over your speed while not exceeding the limit. When you press the accelerator, your automobile will simply accelerate until it reaches the speed you choose and then stop.

What is adaptive cruise control?

Adaptive cruise control, often known as adaptive cruise control (ACC), is a recent feature that was originally seen in more costly vehicles but is now making its way into more affordable vehicles. In comparison to conventional cruise control, it makes substantial improvements since it employs lasers or a radar installed at the front of the vehicle to match your speed with the vehicle in front of you. You may also specify a comfortable distance between you and the car, and the technology will keep that distance constant.

Fortunately, if the automobile in front of you suddenly accelerates, the system will not follow suit.

ACC is known by different titles across automakers, with Mercedes referring to it as ‘Distronic Plus’ and Porsche referring to it as ‘Porsche Active Safe.’ In some cars, such as the Volkswagen Passatven, Traffic Jam Assist is available.

It’s important to note that if the vehicle comes to a complete stop for more than a few seconds, safety regulations dictate that the driver must intervene; pressing the pedal should allow Traffic Jam Assist to restart.
