Operating principle
Fig. 94: Windshield camera
Lane Keep Assist helps the driver keep the vehicle in
the lane. The system uses the front camera (A) to
detect the course of the road ahead based on the
lane markings and initiates corrective steering inter-
vention when the vehicle approaches a detected lane
marking and is in danger of leaving the driving lane.
However, the driver can override this steering inter-
vention at any time.
If the vehicle crosses a lane marking without acti-
vating a turn signal, the system can alert the driver
acoustically. The acoustic warning must be switched
on in the central display for this to happen. If the
vehicle crosses a lane marking after the driver has
activated a turn signal, the system does not issue a
warning or steer because the lane change is inter-
preted as intentional in this case.
The system is designed for driving on highways and
well-surfaced country roads in a speed range of ap-
prox. 40 mph – 156 mph (65 km/h – 250 km/h).
Vehicles with Lane Change Assist
If the vehicle is equipped with Lane Change Assist,
the active system warns the driver through correc-
tive steering intervention when changing lanes in a
potentially critical situation. Steering intervention
occurs even if the turn signal is activated for the di-
rection in question. If the steering intervention is
overridden by the driver, an additional warning is
provided via a warning tone (if active).
Behavior if there is no steering activity
The driver's steering behavior is monitored when
Lane Keep Assist is switched on and active. If there
is no steering activity (e.g. hands not on the steering
wheel or only resting lightly), a warning appears in
the instrument cluster. The system prompts the
driver to actively take over the steering. If the driver
does not react to the takeover prompt, the system
switches to a passive state.
