No existing system makes use of satellite or roadside infrastructures nor of cooperative support from other vehicles. Such systems may use a radar or laser sensor or a stereo camera setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows. ACC technology is widely regarded as a key component of any future generations of intelligent cars.
They impact driver safety and convenience as well as increasing capacity of roads by maintaining optimal separation between vehicles and reducing driver errors. Vehicles with autonomous cruise control are considered a Level 1 autonomous car, as defined by SAE International.
For example, Mercedes-Benz packages the radar behind the upper grille in the center and behind a solid plastic panel that has painted slats to simulate the look of the rest of the grille. Single radar systems are the most common. Systems involving multiple sensors use either two similar hardware sensors like the 2010 Audi A8 or the 2010 Volkswagen Touareg, or one central long range radar coupled with two short radar sensors placed on the corners of the vehicle like the BMW 5 and 6 series.
A more recent development is the binocular computer vision system, such as that introduced to the US market in model year 2013 by Subaru. These systems have front-facing video cameras mounted on either side of the rear view mirror and use digital processing to extract depth information from the parallax between the two cameras’ views.

Also in certain cars it is incorporated with a lane maintaining system which provides a power steering assist to reduce steering input burden on corners when the cruise control system is activated.
GPS data can inform the system of geographic features such as a freeway offramp. This could allow a following car to interpret a turn signal by an exit as not requiring the following car to slow down, as the leading car will exit. Predict systems modify speed based on predictions of other vehicles’ behavior. Such systems can make earlier, more moderate adjustments to the predicted behavior, improving safety and passenger comfort.
