ABSTRACT:
In a suspension system of a vehicle which the damping force characteristic is changed into three or more characteristics, the damping force characteristic is changed step by step when the damping force characteristic selected by a given control rule is different from the damping force characteristic at that moment in several steps. Also, the running state is detected by detecting means and the damping force characteristic to be selected is limited to two or so from three or more characteristics according to the vehicle running state. The damping force characteristic is changed only within the above selected damping force characteristics based on a given control rule. Through the above, noise and oscillation caused by large changes of the damping force characteristic can be lowered.
