systems. The multifunction camera is located below
the inside rearview mirror on the windshield and
has the following tasks:
Control of systems
The multifunction camera controls the Adaptive
Highbeam Assist system.
Scanning of sensors, pickups and signals
The input variables and signals are read in by the
multifunction camera via the chassis CAN.
Evaluation of input variables and actuation of
components

microprocessor and the relevant components are
actuated by the multifunction camera over the
chassis CAN.

Design
The multifunction camera consists of the three
main components:
• Camera
• Image recognition module
• Decision module
The multifunction camera evaluates the brightness,
shape, structure and, if necessary, the color and
movement of a detected object to ascertain
whether it is a preceding or oncoming vehicle, a
street lamp, a traffic sign or another part of the road
infrastructure. The image recognition module inte-
grated in the camera estimates the distances to
other road users, evaluates the brightness of the
vehicle's surroundings and recognizes extreme
weather conditions (thick fog, heavy snowfall) and
tunnels.
i Note
If the multifunction camera is removed or the
windshield is replaced, the camera must be cali-
brated using Xentry Diagnostics.
