Module, Central Vision Processing (CVPM): Operation

OPERATION 

For additional information on the SVC system functionality, refer to DESCRIPTION and OPERATION .

Courtesy of CHRYSLER GROUP, LLC

The CVPM (1) 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.

• Acquisition on the CAN-IHS bus of the passenger door ajar signal
• Acquisition on the CAN-IHS bus of the left rear door ajar signal
• Acquisition on the CAN-IHS bus of the right rear door ajar signal
• Acquisition on the CAN-IHS bus of the trunk/tailgate ajar signal
• Acquisition on the CAN-IHS bus of the front left park assist alert signal
• Acquisition on the CAN-IHS bus of the front center park assist alert signal
• Acquisition on the CAN-IHS bus of the front right park assist alert signal
• Acquisition on internal signal Top+Rear when user select Top + Rear soft button
• Acquisition on internal signal Top+Front when user select Top + Front soft button
• Acquisition on internal signal Rear Crosspath when user select Rear Crosspath soft button
• Acquisition on internal signal Front Crosspath when user select Front Crosspath soft button
• Acquisition on internal signal Ronly when user press "R Only" soft button in SVC screen
• Acquisition on internal signal CVPM button press When user press Image defeat on the Radio screen

• Acquisition on CAN-IHS bus signal for air suspension control module present/not present status
• Configuration of the surround view camera image based on the driver DYNAMIC GRIDLINES ON/OFF personalization selection
• Processing of the camera images: Distortion Correction, Projection Transformations
• Blend and Stitch the adjacent camera images together resulting in the surround view camera image
• Overlay a stylized vehicle (including corresponding doors/tailgate open/closed state) on the image relative to the camera view. All combinations of the doors and tailgate open/closed states shall be capable of being displayed
• Overlay soft buttons for selection and display of the default view or other customer-selectable views
• Map touch screen coordinates sent by the Radio to the soft buttons overlays and their associated functionality
• Store and recall dynamic gridline ON/OFF state information over the ignition cycle

Outputs

• Transmission on the CAN-IHS bus of the SVC image personalization selection signal to the Radio to indicate gridline personalization selected by the driver
• Transmission on the CAN-IHS bus of the SVC image defeat signal to the Radio-to-switch head unit and then back to the non-camera display operation
• Transmits a video output signal to the Radio
• Transmission on the CAN-IHS bus of the display view status
