PROBLEM TO BE SOLVED: To provide a vehicular suspension system capable of efficiently performing vehicle height adjustment. SOLUTION: When a vehicle height is adjusted by making a fluid spring cooperate with an electromagnetic actuator, control is performed so as to allow fluid to flow in and out of a fluid spring before the distance between a vehicle body and a wheel reaches a target value h<SP>*</SP>, the distance between the vehicle body and the wheel is changed to an immediately-before distance h<SB>A</SB><SP>*</SP>set on the proximal side from the target distance h<SP>*</SP>, and the force of the actuator is controlled to be reduced after reaching the immediately-before distance h<SB>A</SB><SP>*</SP>. As shown in Fig. 9(b), air continuously flows into an air spring even after the distance between the vehicle body and the wheel reaches the immediately-before distance h<SB>A</SB><SP>*</SP>by the actuator, and a force necessary for maintaining the subsequent target distance h<SP>*</SP>can be made to depend on by the air spring. Thus, power consumption can be suppressed, and the efficient vehicle height adjustment is achieved. COPYRIGHT: (C)2008,JPO&INPIT
