Connection of Control Units
Control Unit and Camera
The Night Vision control unit and the Night Vision camera are connected via the following cables:
- LIN bus; Diagnosis, programming and camera control
- Sym. Video; Video signal from the camera
- CAN_POW; Power supply from control unit to camera, heating of camera lens
- Ground; Common earth/ground of camera and control unit for suppressing interference
The video signal between the camera and the control unit is transmitted via two cables as a symmetrical, Analog video differential signal.
In the control unit the differential signal is converted into a CVBS signal and, depending on the equipment specification, transmitted to the navigation system or the video module.
The camera is powered under the following conditions:
- Switching on of BMW Night Vision by the button in the light switch center
- Rain/light sensor detects dusk/half-light (driving lights are switched on)
The BMW Night Vision control unit is powered by the front distribution box via term. 30B.
K-CAN
The K-CAN connection of the Night Vision control unit serves to transmit the diagnosis and programming data and to read out the information from the RLS (brightness), the LM (driving lights on) and DSC (yaw rate, speed and steering angle). The signals from DSC are placed on the K-CAN via the SGM. In addition, the control unit receives information on the terminal status via the K-CAN.
