REAR VIEW MONITOR SYSTEM


System Description


CAMERA IMAGE OPERATION PRINCIPLE
- Power is supplied to rear view camera from camera control unit and the rear view camera outputs the camera image to camera control unit when selector lever is set to reverse position and the reverse signal on camera control unit is input.
- Camera control unit superimposes the guiding line and predicted course line to the image from rear view camera and outputs to front display unit. In this case, the reverse signal is also input to AV control unit.
Therefore, AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the image displayed by the communication signal between AV control unit and front display unit with the camera image.
- AV control unit outputs camera image signal that is inputted from camera control unit to front display unit.
- Camera control unit controls the direction and distance of predicted course line according to the sensor signal from steering angle sensor.
- Steering angle sensor connected to the AV control unit and transmits the steering angle signal via CAN communication.
- AV control unit determines whether rear view camera is equipped or not, based on the presence of camera connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when rear view camera is equipped.
- Warning message under the rear view monitor display is described by AV control unit.
