GF54.21-P-3300FL Component Description For Multifunction Camera
- with CODE (238) Active Lane Keeping Assist
- with CODE (476) Automatic lane recognition
- with CODE (513) Speed Limit Assit
- with CODE (608) Adaptive high beams assist

Component Identification:

Location
The multifunction camera is located underneath the inside rearview mirror (A67) on the windshield.

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
^ Output of requests

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
Input factors are evaluated by the integrated microprocessor whereupon the corresponding requests are then issued.

Control of systems
The multifunction camera controls the following systems:
- Active Lane Keeping Assist (with 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 a hot-print is applied to the windshield. This is actuated by the multifunction camera.

Output of requests
The signals are transmitted 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 [MFK] consists of the following main components which are integrated in a housing:
- Multifunction camera
- Multifunction camera control unit
- Multifunction camera heater

The multifunction camera should be calibrated after exchanging the multifunction camera or windshield.
