Connection of Control Units and Camera
The Night Vision 2 control unit and the night vision camera are connected through the following cables:
- Private CAN-bus; Diagnosis, programming and camera control
- LVDS-Video; Video signal from the camera
- CAN_POW; Power supply from control unit to camera, heating of camera lens
- Ground; Common ground of camera and control unit for suppressing interference.
The video signal is sent via a shielded LVDS cable between the camera and control unit. In the control unit the signal is converted into an dCVBS (d = differential) video signal and, depending on the equipment specification, transmitted to the CIC or the video switch.
The camera is powered under the following conditions:
- BMW Night Vision 2 switched on by pressing button in control panel of driver assist systems BEFAS
- Rain-driving lights sensor detects twilight or darkness.
The BMW Night Vision 2 control unit is powered by the rear distribution box via terminal 15N.
PT-CAN
The PT-CAN connection of the Night Vision 2 control unit serves to transmit the diagnosis and programming data and to read out the information from the RLS (brightness), the JB (driving lights status, wiper speed) and ICM (road speed and yaw rate). In addition, the terminal status and the vehicle identification number (VIN) are transferred to the control unit via the PT-CAN.
