Abstract
A suspension control apparatus and a method for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for suspending the corresponding road wheel from the vehicle body. The suspension control apparatus includes a control unit which is connected to receive the output signals from an acceleration sensor, a vehicle-speed sensor and a steering sensor for calculating the rolling state of the vehicle due to a transverse acceleration thereof and controlling the respective suspension units based on the calculated rolling state of the vehicle so as to suppress the rolling thereof. The control unit serves to determine the period or frequency of change or reversal of the direction of the detected transverse acceleration of the vehicle, and control the suspension units so as to stop the roll-suppression control when the frequency of reversal exceeds a prescribed level. The control unit further performs the first roll-suppression control operation and stop subsequent roll-suppression control operations from the instant when the frequency of reversal of the direction of the transverse acceleration exceeds the prescribed level.
