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.

摘要： A wheeled vehicle is equipped with a feedforward steering control system which steers the vehicle through front or rear road wheels in accordance with a driver's steering input such as an angular displacement of a steering wheel, and a negative feedback system which senses a turning behavior of the vehicle such as a yaw rate or a lateral acceleration, and steers the vehicle through the front or rear wheels in such a negative direction as to reduce the turning behavior. The feedforward system may control the angular direction of the front or rear wheels in accordance with a linear combination of the steering input and the time derivative of the steering input, or may control the angular directions of both of the front and rear wheels in accordance with different transfer functions between the steering input and the front and rear wheel angles. The negative feedback system is combined with the feedforward system in various ways to provide desired characteristics of the turning behavior. The negative feedback quantity determined by the negative feedback system may be proportional to the sensed turning behavior, or may be determined in accordance with the difference between the sensed turning behavior, and the reference turning behavior calculated from the vehicle speed and steering input.

摘要： A vehicle is equipped with a rear wheel control device including hydraulic actuators for controllably turning rear wheels under influence of hydraulic fluid supplied thereto from a hydraulic pump. Turning the rear wheels is made in one of first and second directions which are opposite to each other, in response to steering effort applied to a steering wheel. The change-over operation of the rear wheel turning between the first and second directions takes place upon substantially stopping supply of the hydraulic fluid to the actuators, thereby preventing shock during the turning direction change-over operation.

摘要： A vehicle steering control system for steering both front and rear wheels is so arranged that a transfer function between a driver's steering input and a front wheel steering angle, and a transfer function between the steering input and a rear wheel steering angle are differentiated from each other so as to obtain an optimum cornering characteristic of the vehicle. The system has a steering input sensor, a vehicle speed sensor, means for determining the transfer function for the front wheels from a steering frequency and a vehicle speed, means for determining the transfer function of the rear wheels, a front wheel actuator for steering the front wheels, and a rear wheel actuator for steering the rear wheels. The means for determining the transfer function of the rear wheels may be an electronic circuit, or a hydraulic fluid flow restrictor such as an orifice, or a mechanical gearing.

摘要： A method of controlling an automotive vehicle is disclosed whereby a steering characteristic of the vehicle is automatically adjustable to a feature of the driver's steering the vehicle. The feature of the driver's steering the vehicle is detected in terms of a driver's technique or habit in manipulating a steering wheel or a motion characteristic of the vehicle such as a yaw rate or a lateral acceleration resulting from a driver's manipulating the steering wheel. A pair of steerable road wheels, such as a pair of front road wheels, are steered through an angle which is proportioned to an angle through which the steering wheel is manually turned at a ratio which is variable with variation in the feature of the driver's steering the vehicle.

摘要： A vehicle is equipped with a power steering system having a power cylinder, and a vehicle control mechanism having an actuator. The power cylinder and the actuator are supplied with hydraulic fluid under pressure through first and second control valves, respectively, to independently control the power steering control system and the vehicle control mechanism. The first and second control valves are configurated integrally with each other to form a single control valve assembly, thereby providing advantages of weight, production cost, and required space reductions.

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.
