A40/11 Multifunction camera

Location
The multifunction camera is under a cover at the top center of the windshield.

Task
The multifunction camera records pictures of the area in front of the vehicle. The pictures are processed in the multifunction camera's internal control unit and used for implementation of the camera-based driver assistance systems.
The multifunction camera has the following tasks:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Control of systems
^ Actuation of components

Reading in of sensors, pickups and signals
The input factors are read in over the chassis CAN (CAN E).
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.

Control of systems
The multifunction camera controls the following systems:
- Active Lane Keeping Assist (with code (238) Active Lane Keeping Assist)
- Automatic Lane Keeping Assist (with code (476) Lane Keeping Assist)
- Speed Limit Assist (with code (513) Speed Limit Assist)
- Highbeam Assist (with code (608) Adaptive Highbeam Assist)

Actuation of components
The signals are sent by the multifunction camera via the chassis CAN. The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
To avoid any fogging (caused by air humidity) in the multifunction camera's field of view the windshield is heated in this area by the auxiliary heater heating element (R50), which is actuated by the multifunction camera.

Design
The multifunction camera consists of the following main components integrated in a housing:
- Multifunction camera
- Multifunction camera control unit
- Auxiliary heater heating element
The multifunction camera must be recalibrated after replacing the multifunction camera or windshield.
