Ferrari 612 scaglietti Owner's Manual page 125

Specifications
• With independent wheels and upper and lower wishbones.
• Double-acting telescopic hydro-pneumatic shock absorbers, with
variation of the electronically-controlled setting.
• Small kingpin offset, to improve braking stability and reduce
vibrations on the steering wheel.
• Anti-dive configuration due to the upper arm being tilted to reduce
front pitching when braking.
• A single, double-row ball bearing is fitted on the wheel hub, which
does not require maintenance.
• Transverse stabiliser bars.
The features of the system with which the vehicle is equipped are
varied hydraulically and electronically during use, according to the
driving and load conditions.
Electronically-controlled active suspension with
"Skyhook" constant damping
The suspension uses the "Skyhook" system developed by
Mannesmann-Sachs and optimised by Ferrari for automatic,
continuous control of the damping force by means of acceleration
sensors, which detect the movements of every wheel and of the car
body.
A sensor fitted on the steering column detects the position of the
steering wheel (see page 114).
The ECU processes the sensor output data to adapt the suspension
settings to the road and driving conditions in real time, with a response
that is much faster than that of other systems available on the market.
The system is controlled by an ECU which manages the solenoid
valves on each shock absorber in response to the sensor signals, thus
adjusting the suspension damping and setting.
These sensors allow the ECU to calculate the vehicle speed, vertical
and horizontal acceleration, steering angle, as well as the instantaneous
brake system pressure, and also to manage suspension damping.
Operation
The selection button, located on the right-hand side of the steering
wheel (see page 44), can be used to select one of two driving modes:
"Normal" and "SPORT".
When "Normal" is selected, priority is given to comfort and greater
driving stability in low- and medium-grip conditions.
When "SPORT" is selected, the warning light on the instrument panel
illuminates (see page 31); in this mode, priority is given to traction
allowing a racing-style driving with a better grip on the road.
Depending on the mode selected through the button, the ECU adjusts
the setting curves.
