High dynamic behaviours, driving on the
lane boundary, off course will prevent
the function from working.
FCW braking and stability system
interventions (ESC, ABS) will also
prevent the system from operating.
Changing lane results in system
inhibition for a certain time. In
addition, the road must respect some
characteristics such as minimum
maximum width, lane clearly defined by
two lane boundaries and only in limited
cases for a limited time at least one.
The ALM system is active both in the
case of both lines visible and available
for the system, and in case of the only
line available on the road.
Each ALM intervention is notified to the
driver with the relative graphics which
is shown for the entire duration of the
system intervention and for a minimum
time of 1 second.
Multiple interventions are allowed both
in terms of visual and acoustic signals
and in terms of steering torque.
If more then three consecutive
interventions are required within a period
of 180 seconds, starting from the second
intervention the acoustic signal will last
10 seconds longer the previous one.
Starting from the third acoustic signal
the system will emit a continuous sound
and a message on the display will
indicate to keep the centre line.
NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize any risks.
The system is developed to work
only on the lines painted on the road
surfaces, but it may happen that
shadows, traces of old lines, road
edges, etc. are also interpreted as
such.
The system warns the driver with a
pop-up if the vehicle stays near the
lane for more than 10 seconds.
The system is not available when in
CORSA mode.
Being this function used to prevent
unintentional lane change/lane drift,
it will be temporary suppressed/
inhibited by a turn indicator activation,
therefore, graphic warning, steering
torque application and vibration will
be terminated. In these conditions the
graphics turn grey.
Function Description and
Operating Mode
The function intent is to prevent the lane
departure by warning the driver through
indication on the cluster and if set
applying steering torque and vibration.
Driver Assistance Systems
The graphic intent is to represent at
the glance the system knowledge of
the lane in front of the car, the system
suppression status and warning.
For this a simple colour code has been
adopted for each line (of the two
presented):
Both grey lines means system enable,
not able to operate (suppression
condition present or lane detection
system not able to estimate properly
the lane);
Left/right grey line: the lane detection
system is not able to detect that
specific lane boundary;
Yellow line: there is a steering torque
intervention in progress that tries to
prevent a departure on that side, in this
situation the warning should increase
the driver attention requiring him to
properly handle the situation;
Yellow flashing line: the graphic is
shown whenever the system detects
a very imminent lane departure, at
this can be added torque and steering
vibration if configured by the customer.
The white lines (one or both) indicates
that the corresponding lane boundary is
detected and the system is capable to
intervene on it.
Whenever the system is enabled there
will be graphic on the dedicated screen
of the "Driver Assist" page.
