The Adaptive Cruise Control (ACC) sensor contains the software required to operate normal Cruise Control, ACC+, and Forward Collision Warning Plus (FCW+). The ACC sensor determines the distance to a target vehicle and the speed at which the target vehicle is approached. If the ACC sensor determines that intervention is required, the ACC sensor sends a message to other modules over Controller Area Network (CAN)-C to activate audible, visual and haptic warnings. The ACC sensor also sends torque requests to the Powertrain Control Module (PCM) and brake requests to the Antilock Brake System (ABS) module.
