ABSTRACT:
In a four-wheel steering system for steering front and rear wheels of a vehicle in opposite directions in a low vehicle speed range, a rear wheel steering method steers the rear wheels more greatly in a predetermined low vehicle speed range in which a vehicle is usually steered by large angles than in a very low vehicle speed range lower than the predetermined range. The method insures a small turn of the vehicle while suppressing a change in the radius of a turn relative to the operation of a steering wheel immediately after the start of the vehicle.
