摘要：
A four-wheel steering apparatus for a vehicle includes a hydraulic actuator for steering the rear wheels, and first and second oil pumps. An in-phase steering control valve is connected between the first oil pump and the actuator and outputs first hydraulic output for steering the rear wheels in phase with the front wheels in accordance with a steering state of the front wheels. An antiphase steering control valve is connected between the second oil pump and the actuator and outputs second hydraulic output for steering the rear wheels in opposite phase to the front wheels in accordance with a rate of change in the steering state of the front wheels. The hydraulic actuator combines the first and second hydraulic outputs from the control valves and steers the rear wheels in accordance with the difference between the hydraulic outputs.
