ントローラと、を備えた後輪操舵装置。 A pair of solenoid valves are attached to the left and right oil chambers of the rear wheel steering cylinder, which are defined by pistons, to adjust the amount of oil supplied from the pump to the rear wheel steering cylinder, and to detect the running state of the vehicle. An excitation signal is output to the solenoid valve based on a differential control value between a rear wheel steering angle value calculated based on a signal from the sensor and an input value from the rear wheel steering angle sensor, and an excitation signal is output to the rear wheel steering cylinder. a controller that outputs an excitation signal to the solenoid valve based on a comparison value between a pair of hydraulic pressure sensors that detect oil pressures in left and right oil chambers and the differential control value; .
