ABSTRACT:
A motor vehicle steering system for steering rearward wheels as well as forward wheels. The steering system includes a sensor for sensing at least a turning motion of the motor vehicle, a computer for processing signals from the sensor, and an actuator controllable by the computer for steering the rearward wheels in order to meet driving conditions of the vehicle while turning, as much as possible. The sensor may comprise a lateral acceleration or yaw angular velocity sensor, or a combination of a steering angle sensor and a lateral acceleration or yaw angular velocity sensor, or a combination of a steering angle sensor and an acceleration and deceleration sensor, or the like. A steered angle ratio .gamma. of the rearward wheels to forward wheels is selected to be in the range of 0<.gamma..ltoreq.0.6 when the vehicle is moving at a speed of 80 km/h or higher.
