Location
The multifunction camera is located at the top center under a cover on the front window.
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
- Component actuation
Reading in of sensors, pickups and signals
The input factors are read in over the chassis CAN (CAN E). The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Evaluation of input factors
The input factors are evaluated by the integrated microprocessor and the corresponding components are actuated.
Control of systems
The multifunction camera controls the following systems:
- Active Lane Keeping Assist
(for code (238) Active Lane Keeping Assist)
- Automatic lane recognition
(with code (476) Automatic lane recognition)
- Speed Limit Assist
(with code (513) Speed Limit Assist)
- Highbeam Assist
(with code (608) Adaptive Highbeam Assist)
Component actuation
The signals are transmitted by the multifunction camera over the chassis CAN. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
To avoid any fogging in the multifunction camera's field of view the front window is heated in this area by the auxiliary heater heating element (R50), which is actuated directly 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 should be calibrated again after exchanging the multifunction camera or windshield.
