Suspension damping control system
The magnetorheological (MR) fluid is an oil containing a suspension of spherical ferromagnetic particles
measuring a few microns in diameter.
Using an electric current to apply a magnetic field to the oil, the viscosity of the oil may be varied.
By varying the magnetic field applied to the MR fluid flowing in a duct, its pressure and flow rate characteristics
may be adjusted in real time without the use of any external mechanical moving parts or actuators.
As well as ensuring the perfect balance between handling and comfort at all times, through specific calibrations
selectable from the Manettino driving mode selector, this system can also shift the bias slightly towards one
or the other of these two aspects.
Three different calibration levels are used on this vehicle:
Level 1 (COMFORT): a slightly softer calibration optimised to absorb bumps better and to offer improved grip
in wet conditions ("Low Grip" Manettino setting).
Level 2 (SPORT): a slightly stiffer calibration optimised for sports and high speed use (in medium to high grip
conditions) without drastically compromising comfort (SPORT and ESC OFF Manettino settings).
Level 3 (RACE): an even stiffer calibration optimised for track use (RACE, CT OFF and CST OFF Manettino
settings).
