The application of torque, as well as of the
vibration, is suppressed/inhibited if:
The torque given by the driver of the
steering wheel is high
Lateral acceleration is high
The trailer is connected to the correct
control module
At least one hand is not detected on the
steering wheel for longer than a specific
time
The turn signal is turned off
NOTE:
The steering wheel torque is not applied if the
system is unable to detect a lane and if the
direction indicator for the appropriate side has
not been switched on.
The steering wheel detects the presence of
the driver’s hands by a capacitive sensor
installed in the steering wheel and by the
applied torque measured on the steering
column.
System availability
Aggressive driving of the car, or driving on the
median lines, will prevent the correct opera
-
tion of the system.
In case of intervention of the stability and
braking systems (FCW, ESC, ABS) they will
prevent the system from operating.
Lane change will disable the system for a
certain period of time.
The road must also comply with some specific
characteristics, such as:
Maximum/minimum lane width.
Clearly identified and defined double yellow
lines and, for a limited period of time, a lane
with a single demarcation line.
NOTE:
In some cases, for a limited period of time, the
system may be activated by a lane with a
single median line.
In cases of good road surface conditions, the
system could correctly recognize other types
of valid lane markings (e.g. road edges, side
-
walks, etc.).
Hands Presence On The Steering Wheel
Detection
The system is able to detect the presence of
the driver’s hands on the steering wheel.
When the system does not detect the pres
-
ence of hands on the steering wheel for 0 to 6
seconds, the following screen will be displayed
on the instrument cluster display. No acoustic
warning will be emitted in this case.
Hand Presence On The Steering Wheel Not
Detected Display (Up To 6 Seconds)
When the system does not detect the pres
-
ence of hands on the steering wheel from 6 to
15 seconds, the following screen will be
displayed on the instrument cluster display. A
short acoustic signal will sound if hands are
not detected on the steering wheel for 6 to
12 seconds. A continuous signal will sound if
hands are not detected on the steering wheel
for 12 to 15 seconds.
Hand Presence On The Steering Wheel Not
Detected Display (6 To 15 Seconds)
