Audi active lane assist
Description
Applies to: vehicles with Audi active lane assist
Active lane assist detects lane marker lines with-
in the limits of the system using a camera in the
windshield. If you are approaching a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you with
corrective steering . You can override this steering
at any time . If you pass over a line, the steer ing
wheel will vibrate lightly. In order for this warn-
ing vibration to occur, it must first be switched
on in the Infotainment system . Active lane assist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle.
The system is designed for driving on express -
ways and highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
Applies to: vehicles with side assist
If you activate a turn signal when active lane as-
sist is ready and it classifies a lane change as crit-
ical because of vehicles traveling alongside you or
approaching you, there will be noticeable correc-
Assistance systems
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
Applies to: vehicles w it hout side assist
The system will not warn you before crossing a
lane marker line if you have activated the turn
signal. In this case, it assumes that you are
changing lanes intentionally.
Applies to: vehicles w ith adaptive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition to the lane marker
lines, the system can also take into account other
objects such as guard rails . If they are detected in
close proximity to the vehicle, active lane assist
helps prevent the vehicle from driving too close
to them. There is also passing ass istance. The
system does not provide any corrective steering if
it detects that you are passing another vehicle.
A WARNING
~
-
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al-
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc-
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi-
bly be identified unintentionally as lane
marker lines. As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex-
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. This can result in active lane assist
not detecting the lane marker lines or de-
tecting them incorrectly .
