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 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 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 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 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 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.
