Claims

[Scope of utility model registration request]

a hydraulic pump driven by an engine; a hydraulic actuator that is interposed between the wheels of the vehicle and the vehicle body and operates in response to the hydraulic pressure from the hydraulic pump, and is capable of increasing and decreasing the force supporting the vehicle body with respect to the wheels; A control valve provided between the hydraulic pump and the hydraulic actuator to control the supply and discharge of hydraulic pressure to the hydraulic actuator, a driving state detecting means for detecting the traveling state of the vehicle, and a detection output of the driving state detecting means. In the active suspension for a vehicle, the active suspension for a vehicle has a control means for controlling the operation of the control valve based on the control means, further comprising: a high pressure oil passage between the hydraulic pump and the control valve being provided in a relief oil passage communicating with the low pressure oil passage. an electromagnetic relief valve with variable relief pressure that controls the supply pressure to the control valve side, a start detection means that detects a start operation of the vehicle, and when a start operation of the vehicle is detected by the detection output of the start detection means. An active suspension for a vehicle, comprising: relief pressure control means configured to operate the electromagnetic relief valve to reduce the relief pressure.
