Adaptive Cruise Control (ACC)12 controls speed and the following interval to the vehicle detected ahead.
As with a conventional cruise-control system, Adaptive Cruise Control (ACC) allows the driver to set a desired speed. But ACC goes a step further, allowing the driver to set a desired speed and the following interval behind a vehicle detected ahead.
While driving, engagement of Adaptive Cruise Control allows the driver to select a short, medium, long or extra-long interval behind the vehicle detected ahead.
ACC then modulates the throttle and applies moderate braking, if necessary, to hold the selected following interval.
