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.
This phenomenon makes it possible to create "virtual valves"; 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.
This makes the following possible:
Higher control frequencies and faster response times for the system;
Greater efficiency in all road conditions with superlative body control, keeping the vehicle glued to the
road in all conditions;
Improved comfort with less disturbance, variations and shocks transmitted from the road.
System layout
The system consists of:
4 NRRPS (Non-Contacting Ratiometer Rotational Position Sensor) sensors installed on the suspension of
each wheel, in which the fixed part of the potentiometer is mounted on the chassis (sprung mass) while
the rotating part of the potentiometer moves together with the suspension. The sensors transmit a
linear signal to the NCS ECU proportional to the angle of movement;
NCS ECU, installed under the hatch cover in the passenger side footrest mat which, in relation to the
signals received from the four NRRPS sensors, the data provided by the ECUs connected to the NCS
and the Manettino setting, controls the damping function of the shock absorbers;
4 magnetorheological shock absorbers, with one for each wheel suspension, controlled by the NCS
ECU in relation to the signals received by the latter.
