Location
The multifunction camera is located at top center under a panel on the windshield.
Tasks
The multifunction camera records pictures of the area in front of the vehicle. These data are processed in the integrated control unit and are used in the implementation of various functions.
The multifunction camera has the following tasks:
- Reading in of sensors and signals
- Evaluation of input factors
- Controlling functions
- Actuation of components
Reading in of sensors and signals
The input factors are read in via chassis CAN 2 (CAN E2) as of 01.03.2016 and via the chassis CAN (CAN E) up to 29.02.2016.
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 are evaluated by the microprocessor and the corresponding components are actuated.
Controlling functions
The multifunction camera controls the following functions:
- Automatic lane recognition (with code 476 (Lane Keeping Assist))
- Speed Limit Assist (as of 01.03.2016 with code 513 (Traffic Sign Assist), up to 29.02.2016 with code 513 (Speed Limit Assist))
- Automatic high beams (with code 608 (Adaptive Highbeam Assist))
To prevent fogging in the field of view of the multifunction camera, this part of the windshield is heated. The auxiliary heater heating element (R50) is directly actuated by the multifunction camera.
Actuation of components
The signals are transmitted by the multifunction camera via chassis CAN 2 (CAN E2) as of 01.03.2016 and via the chassis CAN (CAN E) up to 29.02.2016. The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Design
The multifunction camera consists of the following main components which are accommodated in one housing:
- Multifunction camera
- integral control unit
- Auxiliary heater heating element
After replacement of a multifunction camera or the windshield the multifunction camera has to be recalibrated.
