PROBLEM TO BE SOLVED: To always realize a smooth steering operation while reducing a consumed power. SOLUTION: A steering wheel angle sensor 1 detects a rotation speed of a steering wheel 101. A tire angel sensor 2 detects a turning angle-of a tire 110. A controller 4 drives a motor 106 based on an output of the steering wheel angle sensor 1 and the tire angel sensor 2. An oil pump 105 generates hydraulics in accordance with a rotation speed of the motor 106. A steering valve 107 determines a supply/discharge direction of a hydraulic fluid to be supplied to a PS cylinder 108 in accordance with an operation of the steering wheel 101. The PS cylinder 108 changes the angle of the tire 110 based on the given hydraulics. |
