Cruise control is still the more prolific of speed controls offered on today’s new cars, but adaptive cruise control has started gaining ground. If the vehicle in front of you slows down, your vehicle will slow itself down automatically. This is the major benefit of adaptive cruise control, and it can save you from lots of maneuvering when sitting in traffic or another dull situation. Many vehicle owners are familiar with cruise control, and this basic technology is offered on most vehicles today.

To do it, a car must be equipped with sensors that allow it to detect nearby vehicles and potential obstacles. Most adaptive cruise control systems use radar, with high resolution radar on the horizon, although a camera and lidar (which works on the same principle as radar, but with light waves) can be used as well. You can often spot these cameras integrated into the grille or mounted behind the windshield. These sensors communicate with a computer that controls the throttle and, sometimes, the brakes and the steering system.

Adaptive Cruise Control has limited braking capability, so if the vehicle you’re following stops too suddenly, you’ll get an alert to take action by quickly applying the brakes yourself. Our vehicles will inspire drivers like you to become a Subaru owner for life. Maintaining consistent speeds and avoiding unnecessary acceleration and deceleration also optimizes fuel consumption. Less fuel equals more sustainability and a step closer to a greener future on the road with fewer emissions. General Motors autonomous car unit, Cruise, has started to offer driverless rides to residents of San Francisco as it moves toward the launch of a full-fledged robo-taxi service.

Adaptive cruise control automatically controls the acceleration and braking of a vehicle. Technology, such as adaptive cruise control, can help reduce some of those issues and guard against accidents and other problems. This modern technology is only offered on some vehicles today, but it's worth getting for many buyers. Before you can decide if you want to pay for this technology, you should know what it is, how it works, and why it's beneficial to you. If your vehicle has this available feature, Adaptive Cruise Control† allows you to automatically follow a detected vehicle ahead at a driver-selected following gap. Cameras contribute with visual information, helping the system identify and track vehicles ahead.

Assisting systems
Generally, the dedicated ACC button or switch is located on the steering wheel or control panel. Pressing or toggling this mechanism allows the driver to set their initial cruising speed. In some systems, drivers can also set their desired following distance. A radar and camera-based system, like Mercedes-Benz’s Distronic Plus system, uses both radars and cameras to scan the road ahead.
“There are a few systems out there that don’t bring the car all the way to a stop but instead just shut off at low speeds. That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive. Early systems didn’t allow for presetting the maintained following distance. Consequently, a vehicle six or seven car lengths ahead of you moving into your lane became almost an airbag-deploying event.
Gathering real-time data on the distance away and speed of the vehicle in front, these sensors allow the ACC system to adjust the car’s speed as-needed. Typically, the driver sets their desired cruising speed when they engage ACC on the highway. The system then automatically accelerates and decelerates to stay at a safe distance from other cars within the flow of traffic. Additionally, ACC encourages safe driving practices and helps reduce crash risk by monitoring following distance and alerting the driver or intervening if a vehicle is quickly approaching. Drivers using ACC may also see improved fuel efficiency, especially on the highway, since the system helps maintain an even speed and reduces unnecessary acceleration and braking.
Yes, you will find aftermarket adaptive cruise control kits available. Depending on the features, they range in cost from $250 to nearly $4,000. For most involved electric-system installations, it’s best to get them done by a dealership or certified mechanic. Installation cost depends on the sophistication of the system and the vehicle model. They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels.
The future of mobility is connected
The technology also helps you avoid hitting other people if you get distracted while driving. Adaptive cruise control is a special safety feature that enables your vehicle to control its speed and select other features some of the time. This feature lets your car slow down when necessary to avoid collisions or when your vehicle is too close to the other drivers on the road. This is really helpful while driving on the highways and during traffic jams. The system depends on sensors to figure out what's going on, and they combine with internal electronics to keep your car under control and help you stay a healthy distance from other vehicles, no matter where you're driving.
We’ll also touch upon other radar, lidar and camera-based active safety technologies that adaptive cruise control technology helped to make possible, such as collision mitigation braking. It’s no surprise that an automaker obsessed with safety was an early adopter of adaptive cruise control. Volvo was also one of the first automakers to pair the technology with autonomous emergency braking, allowing a car to both automatically follow a vehicle in front and brake if it encounters an obstacle.

Not only does the system rely on an array of cameras, radar, and lidar, but Cadillac also mapped 200,000 miles of highway. Super Cruise also has a driver-facing camera, and will only work if a certain level of driver alertness is maintained. It maintains a set speed for your vehicle, like a conventional cruise control system, but it also adjusts the speed based on the traffic flow. Better systems can come you a full stop in heavy traffic and continue when congestion lightens.
This feature functions seamlessly as part of our EyeSight® Driver Assist technology—a comprehensive suite of safety features designed to enhance the driving experience. Nearly all Subaru models and trims come standard with EyeSight and Advanced Adaptive Cruise Control, including some of our most popular models like the Outback, Forester, Crosstrek, and Impreza. EyeSight is an available feature on our performance sports models with automatic transmissions, including the WRX and the BRZ, as well as those with manual transmissions. Once in operation, the ACC system remains working until the driver disengages by either pressing the brake pedal or manually deactivating the system using the dedicated switch or button. Sometimes, ACC will use visual and audio cues to alert the driver to brake if it detects a possible collision ahead.
