Claims

[Scope of Claim for Utility Model Registration] Hydraulic support means that are interposed between the vehicle body and each wheel to hydraulically support the vehicle body, and each hydraulic support means that is based on the vertical acceleration of the vehicle body at each wheel. In an active suspension system for a vehicle, the vehicle active suspension device is equipped with a hydraulic control means for controlling the supply and discharge of hydraulic pressure to and from the vehicle body, the roll angular velocity detection means for detecting the roll angular velocity of the vehicle body, and the pitch angular velocity detection means for detecting the pitch angular velocity of the vehicle body. , one vertical acceleration sensor that detects the vertical acceleration of the vehicle body, and the vertical acceleration of the vehicle body at each wheel portion is calculated based on the roll angular velocity, pitch angular velocity, and vertical acceleration obtained from these detection means and sensors. What is claimed is: 1. An active suspension device for a vehicle, characterized in that it is equipped with a calculation means for calculating the amount.
