Abstract
A suspension controller for a vehicle which includes a plurality of suspension units containing a hydraulic fluid and which is designed to bear a part or the whole of the load of the vehicle body by utilizing the pressure of the hydraulic fluid and to expand or contract the suspension units by adjusting the amount of hydraulic fluid contained in the suspension units, thereby adjusting the attitude of the vehicle body. An anticipated change in the attitude of the vehicle is estimated from present running conditions of the vehicle, and control of each of the suspension units is started immediately thereafter so as to suppress the change in attitude or change the attitude of the vehicle as desired. Accordingly, it is possible to effectively control the attitude of the vehicle during cornering or at the time of moving the vehicle forward rapidly from start or when the brakes are applied suddenly. Thus, the driving performance is improved by a large margin, and the occupant of the vehicle can be assured of enjoying a comfortable ride.
