Reversing Camera Component Description - GF54.65-P-5040RDM
Model 172.4 as of model year 2017
with code 218 (Rear View Camera)
Illustration shows model 172.4
Location
The reversing camera is located above the license plate number at the left in the trunk lid's handle strip.
Tasks
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 radio (A2). The pictures captured by the reversing camera are processed and electronically corrected accordingly by the integrated control unit before being displayed in the audio/COMMAND 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):
- Circuit 15 status
- Status of reverse gear
- 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)
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
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 issued through the following connections:
- Direct line
- Chassis CAN 2
Direct line
The reversing camera sends the image data via a low voltage differential signal (LVDS) line to the radio.
Chassis CAN 2
The reversing camera also sends the following signals over chassis
CAN 2:
- Reversing camera status
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Body
The reversing camera is a color picture camera with a wide-angle lens (angle of vision ∠ gt 180°) and integrated control unit.
