置。[Scope of claim for utility model registration] An actuator that is installed between the vehicle body and the axle and can be operated by hydraulic pressure to change the vehicle posture, and an actuator that moves the valve spool relative to the valve body based on a control command signal from a controller. a pressure control valve formed to be able to control output hydraulic pressure to the pressure control valve; fail-safe means that operates based on an abnormality occurrence signal from the controller to bring the actuator into a predetermined fail-safe state; provided in the pressure control valve; a position detection means for detecting the relative position of the valve spool with respect to the valve body; and an attitude control calculation unit included in the controller and configured to calculate the vehicle attitude to a predetermined target state based on input information and output the control command signal. , included in the controller, which compares the calculated valve spool position based on the control command signal and the actual valve spool position based on the input signal from the position detection means, and generates an abnormality occurrence signal when the difference between the two exceeds a predetermined value. A vehicle attitude control device comprising: an abnormality determination unit that outputs an output;
