Curbview Vision Camera Description and Operation
The camera(s) do not display children, pedestrians, bicyclists, crossing traffic, animals, or any other object outside of the cameras' field of view, below the bumper, or under the vehicle. Shown distances may be different from actual distances. Do not drive or park the vehicle using only these camera(s). Always check behind and around the vehicle before driving. Failure to use proper care may result in injury, death, or vehicle damage.
The Curbview camera provides a view of the area in front of the vehicle. The display shows a front, top down view at the top and left and right front camera images on the bottom.
The front view appears after shifting from R (Reverse) to a forward gear, or by pressing CAMERA in the center stack, and when the vehicle is moving forward slower than 8 km/h (5 mph).
The curbview camera system consists of the following components:
- B87 Rearview Camera
- B174L Frontview Camera Left
- B174R Frontview Camera Right
- K157 Video Processing Control Module
- A11 Radio OR K74 Human Machine Interface Module
When the vehicle is traveling at speeds slower than 6 mph (10kph) the video processing control module will power up the cameras and send a video signal to the radio or human machine interface module.
The following conditions may cause a degraded surround vision camera image:
- Ice, snow, or mud has built up on the rear vision 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
Rear Vision Camera
When the vehicle is shifted into R (Reverse), the RVC displays an image of the area behind the vehicle in the center stack display. The previous screen displays when the vehicle is shifted out of R (Reverse) after a short delay. To return to the previous screen sooner, press a button on the infotainment system, shift into P (Park), or reach a vehicle speed of 8 km/h (5 mph).
Displayed images may be farther or closer than they appear. The area displayed is limited and objects that are close to either corner of the bumper or under the bumper do not display.
Curbview displays an overhead view of the area surrounding the vehicle, along with the front or rear camera views in the center stack. The front cameras are in the fascia or near the front emblem, and the rear vision camera is above the license plate.
Features of the Curbview Vision System
- Rear camera view is displayed in reverse
- Front camera view alongside overhead view is displayed after shifting out of reverse to Neutral or Drive
- Will display front view when front park assist object is within trigger range calibration value (30 cm (12 in) in a forward gear
- Image is removed from display when vehicle speed exceeds speed calibration (8 km/h (5 mph) or button press / screen touch
System Operation
The video processing control module sends voltage and a constant ground to power the cameras. Video signal + and video signal - circuits carry the video image from the cameras to the video processing control module for processing. The video processing control module will then send the processed image output to infotainment system by Video signal + and video signal - circuits. Additionally, all the video signal circuits are twisted and shielded to prevent any interference which may lead to a loss of video signal resolution and cause a degraded video image. These circuits must not be spliced/removed from shielding or will cause image degradation.
The video processing control module receives serial data information of Steering Wheel angle from Body Control Module during Reverse.
