Theory Of Operation

The Central Vision Processing Module (CVPM) generates the view in the Surround View Camera (SVC) system display according to inputs received from the four external cameras and driver touch screen inputs. The SVC system uses several different types of inputs and outputs from the Body Control Module (BCM), CVPM, and Radio. The CVPM combines the video feeds together and outputs it to the display screen. The CVPM on this model processes four cameras.

The CVPM receives:

• Power from a fuse protected relay within the interior Power Distribution Center (PDC)
• signals from all four cameras
• the reverse gear status
• the steering angle signal
• the vehicle speed signal
• the door ajar switch status for all 4 doors and the tailgate.

The CVPM uses these signals to process and determine dynamic grid line images. The CVPM uses the Controller Area Network-Interior High Speed (CAN-IHS) network to send each of the images to the radio for display.
