Illustrated on model 221.0
Location
The multifunction camera is on the windshield in front of the interior rearview mirror unit (A67).
Task
The multifunction camera records pictures of the area in front of the vehicle. These data are processed in the internal control unit of the multifunction camera and serve the conversion of various functions. 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 via the following connection:
- Chassis CAN (CAN E)
Chassis CAN
The signals are read in by the multifunction camera via the chassis CAN.
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 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)
- Adaptive 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. Heating is controlled by the multifunction camera.
Component actuation
The signals are sent by the multifunction camera via the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Design
The multifunction camera consists of the following main components:
- Multifunction camera
- Multifunction camera control unit
- Multifunction camera heater
The multifunction camera should be calibrated after exchanging the multifunction camera or windshield.
