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.
