Object Detection Description and Operation - Rear Vision Camera
Rear Vision Camera System Operation
When the transmission is placed into REVERSE, a 12 V signal is sent to the navigation unit indicating that camera operation is requested. The navigation unit then supplies reference voltage and ground to the rear vision camera. The rear vision camera sends video information to the navigation unit through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.
The following conditions may cause a degraded rear vision camera image:
| • | Ice, snow, or mud has built up on the rear vision camera |
| • | Extreme light conditions, such as glare from the sun or the headlights of another vehicle |
| • | Damage to the rear of the vehicle |
| • | Extreme high or low temperatures or extreme temperature changes |
If a malfunction is detected in the system, Rear Vision Camera System Unavailable may be displayed on the navigation unit as an indicator to the customer that a problem exists that requires service.
