PURPOSE: To predictively-control a wheel side suspension based on road surface information with objective wheels. CONSTITUTION: A vibrating input with respective wheels is estimated by a microcomputer 44 based on respective detected values by stroke sensors 27FL-27RR located at respective wheel positions and vertical acceleration sensors 28FL-28RR, and an vibrating input component transmitted to the vehicle body side through an attenuation factor out of the vibrating input is multiplied by a control gain (α) smaller than 1 to compute predictive control power for canceling the vibrating input after correction. By controlling respective pressure control valves 20FL-20RR based on the predictive control power, it is possible to prevent an effect of road surface roughness from being transmitted to the vehicle body side by hydraulic cylinders 18FL-18RR, thus ensuring good riding comfort.
