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： A four-wheel steering system for a motor vehicle steers motor vehicle rear wheels based on a steering angle ratio between front and rear wheels based on a vehicle speed, and a front wheel steering angle. The steering angle ratio is of a negative value or a relatively small positive value when the vehicle speed is in a medium speed range or a high speed range and the front wheel steering angle is in a relatively small range. The motor vehicle is controlled to turn well when the front wheel steering angle is in the relative small range while the motor vehicle is running in the medium and high speed ranges.

摘要： A front and rear wheel steering system for a motor vehicle with steerable front and rear road wheels includes a front wheel steering mechanism for steering the front road wheels in response to a steering action effected by a steering wheel of the motor vehicle, a neutral positioning mechanism for normally urging the rear road wheels under a resilient force to a steering neutral position, a rear wheel steering mechanism having an electric motor for steering the rear road wheels out of the steering neutral position, and a controller for controlling an electric current supplied to the electric motor depending on the steering action of the steering wheel. The controller reduces the electric current supplied to the electric motor and subsequently holds the reduced electric current while the motor vehicle is at rest and no steering action is effected by the steering wheel. Preferably, the controller controls the electric current supplied to the electric motor to reach a value which enables the electric motor to produce an output force smaller than the resilient force produced by the neutral positioning mechanism.

摘要： In a vehicle steering system, in particular a steer-by-wire system, using a feedback control including an integral control unit in the feedback path, the integral factor of the integral control unit is made variable depending on the condition of the vehicle, road condition and preference of the vehicle operator so that the intensity of the steering reaction from the tires that is applied to the vehicle operator can be optimally adjusted. Thereby, the steering system can reduce the stead-state deviation and improve the stability in holding a steering angle both without any substantial compromise.

摘要： A steering apparatus for a vehicle is provided, which has a controller, a first device for detection of an amount of manipulation rendered to the controller, a second device for detection of an amount of steering of steerable wheels, a control unit for controlling an amount of steering based on at least the amount of manipulation and a third device for applying a reaction force to the controller. The apparatus has a feature that it includes the sensor for detection of a speed of the vehicle and the control unit determines the reaction force by multiplying a deviation between the amount of manipulation and the amount of steering by a coefficient for vehicle speed, which is adapted to be larger as the speed of the vehicle detected by the sensor increases.

摘要： A current detecting apparatus comprises a determining unit which determines whether the electric potential of a first node or a second node is in a predetermined range. When the condition that the electric potential is not in the predetermined range continues longer than the predetermined period of time, the determining signal indicating the damage occurrence is outputted. Accordingly, the damage of the constituting elements can exactly be determined with the relatively simple configuration in a short time.
