Claims

[Scope of Claim for Utility Model Registration] 1. A hydraulic cylinder that supports the wheels with respect to the vehicle body, a flow control valve that controls the supply and discharge of hydraulic fluid from a hydraulic source to the hydraulic cylinder, and means for detecting the acting load of the hydraulic cylinder. means for calculating a reference load as an average value of the detected load over a predetermined period; means for calculating a target stroke value according to a load variation obtained by comparing the detected load with the reference load; and a target stroke. means for outputting a control signal for the flow control valve in accordance with the value, means for detecting the stroke amount of the hydraulic cylinder, and correcting the control signal for the flow control valve so that the detected stroke amount matches a target stroke value. A suspension system for a vehicle, characterized by comprising means for: 2. Equipped with means for determining the turning state of the vehicle,
2. The suspension system for a vehicle according to claim 1, wherein calculation of the reference load is stopped at the time of determining the turning movement. 3. Equipped with means for determining whether the vehicle is stopped on a slope,
2. The suspension system for a vehicle according to claim 1, wherein calculation of the reference load is stopped at the time of determining whether the vehicle is stopped on a slope.
