The Adaptive Cruise Control (ACC) system automatically adjusts a vehicle's speed to maintain a constant headway between vehicles. A pre-set cruising speed is applied through the automatic adjustment of the throttle by downshifting and/or actuating "feather" braking. A radar headway sensor, hidden behind the grille, detects obstacles ahead and enables the vehicle to travel at a set speed or adapt to the speed of the vehicle in front. An on-board microcomputer processes the radar information and converts the electronic instructions into engine speed or brake pressure.
