摘要：
The purpose of the present invention is to suppress delays in changes in a turning angle with respect to changes in a steering angle, regardless of the type of pump being adopted in an electric hydraulic pressure type steer-by-wire steering system. The steer-by-wire steering system is provided with a hydraulic actuator (6) for changing the turning angle of an object to be steered; a pump (5) for supplying hydraulic pressure to the actuator; an electric motor (4) for rotating the pump in forward and reverse directions; and a control device (3) for controlling the turning angle to be corresponded to a steering angle by operating the motor. The control device is provided with: a motor driving unit for controlling the electric motor to decrease deviations between the steering angle and the turning angle; and a control correction unit for performing changes so as to reduce the time lag between changes in the steering angle and changes in the turning angle, said time lag being derived according to the deviations.
