摘要：
A power steering system includes a hydraulic power cylinder having a first and a second hydraulic chambers, for assisting a steering force of a steering mechanism, a first and a second oil passages respectively connected to the first and second hydraulic chambers, a reversible pump discharging operating oil and providing oil pressure to the hydraulic power cylinder through the first and second oil passages, and a motor connected to the reversible pump and rotating the reversible pump in normal and reverse directions. A steering load detection unit detects a steering load of a steering wheel for steering of the steered road wheels, and a motor control unit outputs a control signal to the motor to bring an actual oil pressure generated by the reversible pump closer to a desired oil pressure determined based on the detected steering load. A discharge amount per rotation of the reversible pump is smaller than or equal to 5 cc.
