Abstract
A steering wheel angle sensor detects the rotational speed of a steering wheel. A wheel angle sensor detects the off-center angle of a wheel. A controller drives a motor based on the outputs of the steering wheel angle sensor and the wheel angle sensor. An oil pump generates an oil pressure according to the revolution speed of the motor. A steering valve determines the supply direction of hydraulic fluid to be supplied to a PS cylinder. The PS cylinder changes the angle of the wheel according to the given oil pressure.
