Object Detection Description and Operation (UVC)

Rearview Camera System Operation

The rearview camera system can help a driver determine how close an object is to the rear bumper within a predefined rearward field of view. The rearview camera system consists of a video camera located at the rear of the vehicle and the navigation radio display.

When the vehicle is running and the transmission is placed into REVERSE, a 12 volt signal is sent to the rearview camera by the body control module (BCM). This signal indicates to the camera that the vehicle is in reverse and image display is requested. The rearview camera receives ignition voltage and a constant ground to power the camera. Video signal + and video signal - circuits carry the video image from the rearview camera to the navigation radio. Additionally, the video signal circuits are shielded to prevent any interference which may lead to a loss of video signal resolution and a degraded video image. The shield is provided a ground path by the rearview camera.

The following conditions may cause a degraded rearview camera image:

* Ice, snow, or mud has built up on the rearview camera
* Dark conditions
* Extreme light conditions, such as glare from the sun or the headlights of another vehicle
* Damage to the rear of the vehicle
* Extreme high temperatures or extreme temperature changes
