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
minimummaximum width, lane clearly
defined by two lane boundaries and
only in limited cases for a limited time
at least one.
The LKA 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 LKA 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 TFT display
will indicate to keep the center 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.
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 gray.
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. The graphic intent is to
represent at the glance the system
knowledge of the lane in front of the
Driver Assistance Systems
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. This
