ペンシヨン装置。 A hydraulic support means that is interposed between the vehicle body and the wheels and changes the support rigidity by controlling the supply and discharge of hydraulic pressure, a vibration input detection means that detects a vibration input object in front of the vehicle, and a vehicle speed detection means that detects the vehicle speed. The time delay from the time when the vibration input detection means detects a vibration input object to the time when vibration is input to the wheel is predicted based on the vehicle speed detected by the vehicle speed detection means, and the hydraulic support is adjusted based on the predicted time delay. hydraulic control means for reducing the support rigidity of the hydraulic support means by outputting a command signal for changing the supply and discharge of hydraulic pressure of the means, the hydraulic control means for at least outputting the command signal; An active suspension device for a vehicle, characterized in that the output is performed earlier than the predicted time delay by the amount of operation delay time required for the support rigidity of the rear hydraulic support means to actually become small.
