ABSTRACT:
An auxiliary steering system for a vehicle is adapted to additionally steer the front wheels and/or rear wheels of a vehicle upon the main steering of the front wheels by a steering maneuver of a steering wheel, while an auxiliary steer angle is determined in accordance with a differential value of a main steer angle of the front wheels. An auxiliary steering system further includes a limiter means adapted to restrict an upper limit of the differential value in accordance with a main steer speed or in accordance with both of the main steer speed and the main steer angle, whereby the auxiliary steer angle does not become too large and a jerk of the vehicle is prevented even if the main steer speed is high, while within a large main steer angle range the auxiliary steer angle is not suppressed and remains capable of compensating for a lowering of a tire cornering power.
