Adaptive cruise control

Adaptive cruise control (ACC) is a type of <a href="/facts/Advanced_driver-assistance_systems/8l0vVnKd">advanced driver-assistance system</a> for <a href="/facts/Road/3aadH4s3">road</a> <a href="/facts/Vehicle/jSIEqANL">vehicles</a> that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. As of 2019, it is also called by 20 unique names that describe that basic functionality. This is also known as Dynamic cruise control.
Control is based on sensor <a href="/facts/Information/3LdrzXtJ">information</a> from on-board <a href="/facts/Sensor/RN8SXbjs">sensors</a>. Such systems may use a <a href="/facts/Radar/jk9BTbFA">radar</a>, <a href="/facts/Lidar/b9SPUmLM">laser</a> sensor or a <a href="/facts/Camera/j4uqsfJQ">camera</a> setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to.
ACC technology is regarded as a key component of future generations of <a href="/facts/Intelligent_car/hhmnmpcu">intelligent cars</a>. The technology enhances passenger safety and convenience as well as increasing <a href="/facts/Traffic_flow/uxRYw4EH">road capacity</a> by maintaining optimal separation between vehicles and reducing driver errors. Vehicles with autonomous cruise control are considered a <a href="/facts/Autonomous_car/KXeFywXS">Level 1</a> <a href="/facts/Autonomous_car/KXeFywXS">autonomous car</a>, as defined by <a href="/facts/SAE_International/cBS1MznQ">SAE International</a>. When combined with another driver assist feature such as <a href="/facts/Lane_centering/BaI2JQGB">lane centering</a>, the vehicle is considered a <a href="/facts/Autonomous_car/KXeFywXS">Level 2</a> autonomous car.
