Reversing camera component description - GF54.65-P-5040CAM
MODEL 207.3/4 as of model year 2014 with CODE 218 (Rear view camera)
Illustration shows model 207.3
Location
The reversing camera is located above the license plate number at the left in the trunk lid's handle strip.
Task
The backup camera does the following:
- Records surrounding area to the rear of the vehicle
- Reading in of signals
- Evaluation of input factors
- Output of signals
Records surrounding area to the rear of the vehicle
The reversing camera is an optical parking aid. Its tasks include the capturing of pictures of the area to the rear of the vehicle, the generation of dynamic guide lines and the sending of the video picture to the COMAND controller unit (A40/3). The pictures captured by the reversing camera are processed and electronically corrected accordingly by the integrated control unit before being displayed in the audio/COMAND display (A40/8). The reversing camera is supplied with voltage by the rear SAM control unit with fuse and relay module (N10/2).
The reversing camera is automatically calibrated with the aid of the integrated control unit.
Reading in of signals
The reversing camera reads in, for example, the following information via chassis CAN 2 (CAN E2):
- Terminal status of terminal 15
- Status of reverse gear
- Reversing camera status
- Vehicle speed displayed by instrument cluster (A1)
- Status of backup lamp switch (S16/2)
- Signals from left front axle RPM sensor (L6/1)
- Signals from right front axle RPM sensor (L6/2)
- Signals from left rear axle RPM sensor (L6/3)
- Signals from right rear axle RPM sensor (L6/4)
- Signals from steering angle sensor (N49)
- Trailer recognition status (with CODE 550 (Trailer hitch))
The functions that use these signals are described in the individual function descriptions.
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.
Output of signals
The signals are sent over the following connection:
- Direct line
- Chassis CAN 2
Direct line
Vehicles up to 30.11.2014:
The reversing camera sends the picture data as Color Video Baseband Signal (CVBS) over an analog video interface to the COMAND controller unit.
Vehicles as of 01.12.2014:
The reversing camera sends the picture data to the COMAND controller unit via a low voltage differential signal (LVDS) line.
Chassis CAN 2
The reversing camera also sends the following signals over chassis CAN 2:
- Request for picture output in Audio/COMAND display
- Reversing camera status
The functions that use these signals are described in the individual function descriptions.
Body
The reversing camera is a color picture camera with a wide-angle lens (angle of vision > 130°) and integrated control unit.
