摘要： A rear wheel steering control system which determines a target rear wheel steering angle in accordance with a steering angle of front wheels of the vehicle and steers the rear wheels so that the rear wheel steering angle is maintained equal to the target rear wheel steering angle, and is arranged not to decrease the difference between the target angle and the actual rear wheel steering angle immediately to zero, but to decrease the difference gradually in accordance with a distance traveled by the vehicle, in order to prevent the rear wheels from being steered too much in a direction opposite to a steered direction of the front wheels especially when the vehicle speed is low, and thereby prevent the rear of the vehicle from bumping against an object lying alongside the vehicle.

摘要： A vehicle steering system comprises a power cylinder drivingly connected to front wheels and forming part of a power steering system, and an actuator drivingly connected to rear wheels and forming part of a so-called compliance steer control system. The power cylinder and the actuator are supplied with hydraulic fluid from a pump through first and second control valves which are operated in response to the turning effort applied to a steering wheel. Additionally, a flow dividing valve is provided to distribute the fluid from the pump into the first and second control valves in a predetermined flow dividing ratio, thereby allowing effective independent operations of the power steering system and the compliance steer control system without affecting each other.

摘要： In addition to a conventional steering system for steering a vehicle through the front wheels in accordance with an angular displacement of the steering wheel, the vehicle is equipped with a negative feedback steering control system which steers the vehicle through the front or rear wheels in accordance with an instantaneous yaw rate of the vehicle. The feedback system has a vehicle behavior sensor for sensing the yaw rate, and an control circuit which determines an actual quantity which is equal to the yaw rate or a linear combination of the yaw rate and the time derivative of the yaw rate and a reference quantity which is a function of the angular displacement and the vehicle speed, so designed as to be approximately equal to the yaw rate if there is no disturbance. The control circuit produces a feedback signal proportional to a difference between the actual quantity multiplied by a first coefficient and the reference quantity multipled by a second coefficient. In response to the feedback signal, an actuator corrects the direction of the front or rear wheels in such a direction as to reduce the yaw rate. A lateral acceleration of the vehicle may be used in place of the yaw rate.

摘要： A lower arm and upper links of a double wishbone type suspension are arranged so that the resulting king pin axis about which a road wheel is pivotal, intersects the wheel rotational axis at or close to the wheel center so as to selectively minimize, neutralize or reverse the toe-out effect produced by a force which acts through the wheel center in the aft direction of the vehicle. The lateral rod which controls the orientation of the road wheel is arranged at a predetermined angle to control the amount of toe-in induced by the application of the above mentioned force and a force which acts laterally inboard along the wheel rotational axis.
