Adaptive Cruise Control

ACC systems are in-vehicle electronic systems that automatically maintain a minimum following interval to a lead vehicle in the same lane. The ACC system utilizes components of the collision warning system and a conventional cruise control system. When a host vehicle with ACC travels above a minimum speed threshold, the ACC system controls the engine throttle and, if available, the engine brake and automatic transmission to maintain the following interval, which the driver can set and adjust. In the absence of a vehicle ahead, the ACC system operates like a conventional cruise control system by maintaining the speed set by the driver. The ACC system notifies the driver if the system detects a malfunction.
