Abstract
Disclosed is a control apparatus for a vehicular suspension system 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 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 apparatus further includes a drift compensator for compensating for a drift of a neutral point of the output signal of the acceleration sensor based on the output signals from the acceleration sensor, the vehicle-speed sensor and the steering sensor signal of the acceleration sensor based on the output signals from the acceleration sensor, the vehicle-speed sensor and the steering sensor.
