Functional Description - Powertrain Control Module (Pcm)

The PCM interfaces with several nodes on the bus network to support ACC/NCC system. The PCM provides information regarding the engine speed, accelerator pedal position, speed limiter status and other performance data for the CADM to use during operation. The PCM receives several torque requests during ACC NCC operation that require it to vary velocity and acceleration of the vehicle. The PCM provides the CADM with torque conditions and availability for the CADM to use in its decision process when calculating torque demands.
