The electronic system managing the
vehicle suspensions is the result of the
sophisticated processing run by the
onboard sensors, which are designed
to optimize performance.
The system is capable of constantly
monitoring suspension damping by
means of the actuator fitted on each
shock absorber. It is possible to adjust
the shock absorber setting according
to the road and to the vehicle dynamic
conditions, improving comfort and
road grip.
By pressing button A, even when the
car is running, the driver can choose a
normal or sport setting for the
suspensions, depending on his/her
own driving style. The system will
operate with a "softer" shock absorber
setting if the normal mode is chosen,
or with a more "rigid" setting if the
SPORT mode is selected.
The system is managed by an electronic
control unit which controls the
solenoid valves on each shock
absorber, modifying their damping
and therefore their setting.
The sensors which allow the ECU to
calculate the car speed, vertical and
lateral acceleration, instantaneous
pressure in the braking system and
thereby to manage the suspension
damping are the following:
– vertical acceleration sensor
– LH front vertical acceleration sensor
– RH front vertical acceleration sensor
– Rear vertical acceleration sensor
– LH front wheel acceleration sensor
– RH front wheel acceleration sensor
– drive speed sensor
– brake pedal switch.
The strategy adopted by the system for
controlling suspension damping is
designed to minimize the vehicle’s
vertical vibrations (rolling and
pitching).
The activation of the SPORT mode with
suspension sport setting also affects
the ASR system and the "Cambiocorsa"
gearbox (when fitted), modifying their
setting as well for a sportier drive.
Self-diagnosis
Each time the engine is started, the
system performs a self-diagnosis,
which indicated by the switching on of
the warning light on the multi-
function display.
