ABSTRACT:
A hydraulic suspension control device includes a real yaw-rate detector means for detecting angular velocity around a vertical axis of a vehicle body and a vehicle speed detector for detecting the vehicle speed and a wheel angular detector for detecting the front wheel angle and a target yaw-rate calculation for calculating the target yaw-rate using signal values from the vehicle speed detector and the wheel angle detector. The electric control device includes a driving circuit which is set to receive a signal of deviation between the real yaw-rate and the target yaw-rate and controls an actuator having a pressure valve and a hydraulic cylinder both of which are controlled by the electric control device so that an instability yawing in vehicle movement such as rear wheel side slips can be prevented during the vehicle turning movement.
