General
The reversing camera allows the driver to view the area behind the vehicle as a live picture. They can choose between various displays for this. The view shown on the reversing camera display is prepared with guide lines. The function is operated via the multimedia system.
Function requirements
- Circuit 15 ON
- Tailgate or rear-end door closed
- No trailer operation (vehicles with trailer hitch)
Function
The reversing camera tasks include recording the area surrounding the vehicle at the rear and the generation of dynamic and static guide lines. The pictures recorded by the reversing camera using an extended angle of vision of 180° are processed accordingly by the integrated control unit. The current driving path displayed in the central display is based on vehicle dimensions, vehicle speed and steering wheel angle.
A warning message appears over the picture displayed in the central display if the tailgate or rear-end door is not closed. The guide lines are hidden from view.
When performing the initial commissioning for the reversing camera, the reversing camera must be recoded using the diagnostic tester. The reversing camera is calibrated automatically following the initial commissioning.
The reversing camera is activated when the reverse gear (vehicles with manual transmission) or drive range "R" (vehicles with automatic transmission) is engaged. The reversing camera evaluates the input parameters and starts recording the surrounding area.
Depending on the vehicle and equipment installed, the picture from the reversing camera can also be displayed using the reversing camera button.
The reversing camera stops recording the surrounding area under the following conditions:
- Vehicle speed during forward travel higher than 12 km/h
- Driving distance during forward travel higher than 10 m
- Time period greater than 255 s with reverse gear (vehicles with manual transmission) not engaged or drive range "R" (vehicles with automatic transmission) not engaged
- Drive range "P" engaged (vehicles with automatic transmission)
- Circuit 15 OFF
The reversing camera picture data is processed by the multimedia system and displayed in the central display. The reversing camera uses the steering wheel angle and stored vehicle parameters (lane and exterior contour of the vehicle) to calculate guide lines, which are superimposed on the display. The steering angle is recorded by the steering wheel angle sensor.
The following displays can be selected:
- Normal view
- Wide angle view
- Trailer view (vehicles with trailer hitch)
The area behind the vehicle is displayed mirror-inverted, as it is in the inside mirror.
The display of the recording of the reversing camera is reduced in the event of an attempted correction (forward travel). The guide lines are shown again when the reverse gear (vehicles with manual transmission) or drive range "R" (vehicles with automatic transmission) is engaged again, taking the following parameters into account:
- Time period less than 255 s
- Vehicle speed below 10 km/h
The picture displayed disappears when these parameters are exceeded. The reversing camera then remains in standby mode.
Functional restrictions
The reversing camera does not operate in the following situations or does so to a limited extent only:
- Tailgate or rear-end door is open
- Heavy rain, snow or fog
- Darkness
- Reversing camera is exposed to extremely bright light.
- Area is illuminated by fluorescent lamps or LEDs (display flicker).
- Fast temperature change, e.g. driving into a heated garage in winter
- Camera lens is dirty or covered up
Additional vehicle attachments mounted at the rear (e.g. license plate bracket or rear bicycle rack) may also restrict the viewing range and other functions of the reversing camera.
