ABSTRACT:
A method and device for controlling the steering of the rear wheels of an automotive vehicle having a four-wheel steering system in which, at least in the vehicle medium or high speed range, the rear wheels are controlled to be steered in the coincident-phase direction relative to the front wheels in accordance with the steering force or the steering angle of the front wheels and with the front-wheel steering speed. The method and device are characterized by controlling, at medium or high vehicle speed, a rear-wheel steering speed reference value determined on the basis of the front-wheel steering speed in the direction for reducing the coincident-phase direction steering speed of the rear wheels for low front-wheel steering speed and in the direction for increasing the coincident-phase direction steering speed of the rear wheels for high front-wheel steering speed.
