Method and device for controlling semiactive suspensions of motor vehicles

Abstract

A control device for a vehicle having at least one semiactive suspension arranged between a vehicle body and a wheel and having a damping coefficient that can be varied in a controlled way by an actuator governed by a control device, the control device including an accelerometric sensor generating a vehicle body acceleration signal; a potentiometer generating a suspension position signal; a signal conditioning unit for the calculation of the vehicle body speed and the damping speed; a fuzzy control unit that calculates the subsequent position of the actuator on the basis of the vehicle body speed and of the damping speed; and a driving unit which generates a control signal for the actuator.
