Adaptive cruise, referred to as ACC, belongs to a kind of automobile cruise, which is equivalent to an upgraded version of constant speed cruise. Constant speed cruise can set the vehicle speed at a certain fixed speed, while adaptive cruise is to set the vehicle speed within a certain speed range and automatically control the vehicle speed according to the distance between the radar (usually marked in front) and the vehicle in front.
Through the feedback information of the radar in front of the vehicle and the calculation of the ECU driving computer, ACC automatic cruise system can judge the road condition according to the moving speed of the objects near the vehicle and control the driving state of the vehicle; By feeding back the accelerator pedal, ACC control unit can decide whether to execute cruise control to reduce driver's fatigue.
When ACC adaptive cruise only works when the vehicle speed is 25KM/h, when the vehicle speed drops below 25km/h, the driver needs to control it manually. By upgrading the system software, the adaptive cruise control system can realize the "stop/start" function to cope with frequent stops and starts when driving in the city (although the speed of the city is complicated, it is not recommended to use it in the city).
