摘要： A front and rear wheel steering device which varies the steering angle ratio of rear wheels relative to the steering angle of front wheels in relation with vehicle speed is utilized to improve the drive response of a vehicle, as well as to improve the maneuverability of the vehicle. By varying the steering angle ratio which is a function of vehicle speed according to the running condition of the vehicle, the interference of the running condition of the vehicle upon the driving response can be reduced. The driving response may be evaluated in terms of yaw rate or lateral acceleration of the vehicle for a certain steering input. The running condition of the vehicle may comprise any combination of vehicle acceleration, friction between tires and the road surface, load acting between front wheels and the road surface, and load acting between rear wheels and the road surface.

摘要： A vehicle capable of performing automatic driving can be braked with a hydraulic braking pressure produced by a master cylinder having a vacuum booster and a hydraulic braking pressure produced by a hydraulic pressure pump provided to an ABS/B-TCS hydraulic pressure control unit. During normal braking, the vehicle performs braking with the hydraulic braking pressure produced by the master cylinder, by controlling a linear solenoid of the vacuum booster in accordance with a command from an automatic driving electronic control unit. If an insufficient braking force is obtained from the hydraulic braking pressure produced by the master cylinder or a failure occurs in the braking system of the master cylinder, the vehicle performs emergency braking with the hydraulic braking pressure produced by the hydraulic pressure pump of the ABS/B-TCS hydraulic pressure control unit HU.

摘要： The steering operation of a motor vehicle with steerable front and rear road wheels is controlled by steering the rear road wheels with an actuator such as an electric motor which produces a steering force dependent on a deviation of the actual rear wheel steering angle from a target rear wheel steering angle. The rear road wheels are thus controlled with a characteristic dependent on the coefficient of friction of a road on which the motor vehicle travels and the steering speed at which the motor vehicle is steered. Typically, a steering control method comprises the steps of detecting the steering angle of the front road wheels, determining a target steering angle for the rear wheels based on the steering angle of the front road wheels, detecting the actual steering angle of the rear road wheels, calculating a steering angle deviation of the actual rear wheel steering angle from the target steering angle, determining a rear wheel steering force based on the steering angle deviation, and steering the rear road wheels to the target steering angle with the determined rear wheel steering force.

摘要： In a front and rear wheel steering device for a vehicle in which the steering angle ratio of the rear wheels relative to the front wheels is variable according to the vehicle speed, by accounting for the magnitude of vehicle acceleration in determining the steering angle ratio of the rear wheels by selecting a mathematical function from a plurality thereof, the vehicle response particularly in high speed range can be improved. Smooth transition from a certain characteristics to another may be achieved either by preparing a number of mathematical functions of vehicle speed for the steering angle ratio of the rear wheels or providing some time delay in the transition from one characteristics to another, preferably in proportion to the magnitude of the vehicle acceleration.
