The electronic system managing the
vehicle suspensions is the result of the
sophisticated processing run by the
onboard sensors, which optimize the
car performance.
The system is capable of constantly
monitoring suspension damping by
means of the actuator fitted on each
shock absorber. It is so possible to
adjust the shock absorber setting
according to the roadbed 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. This way, 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 aims
at minimizing the vehicle’s vertical
vibrations (rolling and pitching).
The activation of the SPORT mode with
suspension sports setting also affects
the ASR system and the "Cambiocorsa"
gearbox (where available), 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.
