ム。 a hydraulic cylinder that supports the wheels relative to the vehicle body;
A flow control valve for controlling the supply and discharge of hydraulic oil from a hydraulic source to the hydraulic cylinder, a means for detecting a stroke value of the hydraulic cylinder, a means for setting a reference stroke value for the hydraulic cylinder, and an excitation stroke for the hydraulic cylinder. a means for setting a value, a means for detecting vehicle speed, an excitation mode changeover switch, and a means for adding a target stroke value in place of the reference stroke value when an input is received from the excitation mode changeover switch when the vehicle is stopped. a calculation means for outputting a swing stroke value; a means for outputting a control signal for a flow control valve in accordance with the target stroke value; and control for the flow control valve so that the detected stroke value matches the target stroke value. A suspension system for a vehicle, comprising: means for correcting a signal.
