摘要： In a steering control system for controlling torque steer in a vehicle equipped with an electric power steering device and a torque split arrangement for individually controlling traction and/or braking force of right and left wheels, a difference in traction and/or braking force between the right and left wheels which may be produced by the torque split arrangement may give rise to torque steer depending on the geometry of the wheel suspension system of the vehicle. The control unit for the electric power steering device additionally receives an additional signal for providing an additional steering torque which is required for canceling the torque steer. Thus, the torque steer can be eliminated both economically and reliably without requiring to modify the wheel suspension system.

摘要： In a steering system which produces a reactive steering assist torque which tends to cancel any unintended or undesired behavior of the vehicle, the control unit for the steering system is prevented from producing any reactive steering assist torque when the vehicle speed is zero so that no reactive steering assist torque may be produced to the discomfort of the vehicle even when the vehicle is being moved by external causes such as when being turned by a turntable or being transported by a car lift or a car carrier.

摘要： In a steering system which produces a reactive steering assist torque which tends to cancel any unintended or undesired behavior of the vehicle, the relationship between the steering angle and the vehicle behavior such as the yaw rate and the lateral acceleration reverses in sense depending on the traveling direction of the vehicle. To prevent the control unit for the steering system from producing any reactive steering assist torque which could worsen the behavior of the vehicle when the vehicle is traveling rearward, the control unit either eliminates or reverses the sense of the reactive steering assist torque when the vehicle is traveling rearward.

摘要： In a steer-by-wire vehicle steering apparatus where a steering operator member is operatively connected to steerable road wheels via an electric wire, a control section controls a steering motor in such a manner that an angle of travel direction of the vehicle and a steering angle of the steering operator agree with each other, and a resistive force generation section generates and imparts a steering resistive force to the steering operator in accordance with an actual steered angle of the steerable road wheels. Thus, the steering apparatus permits the vehicle to be steered with an increased accuracy.

摘要： An auxiliary driving system is provided to ensure that a vehicle equipped with an automatic transmission can be moved or permitted to travel without use of the driving force of the vehicle engine in the event of an emergency. The main driving wheels are normally driven through an engine and an automatic transmission and a pair of auxiliary driving wheels are driven by motors. In a usual state, the motors are used to generate an auxiliary driving force or a creep force in the vehicle. However, if the vehicle engine is stopped due to engine trouble or failure, the motors can be driven based on the amount of accelerator pedal depressed to rotate the auxiliary driving wheels and thereby permit the vehicle to travel. Thus, movement of the vehicle can be easily accommodated in the event of an emergency such as when the vehicle engine has failed.

摘要： A camber control system varies the camber of a wheel of a motor vehicle. The camber control system includes a detector for detecting a direction in which front wheels are steered, a controller for producing a control signal in response to a signal produced by the detector, an actuator operable in response to the control signal from the controller, and a rear wheel camber varying mechanism actuatable by the actuator for varying the camber of rear wheels. The controller is arranged such that the control signal produced thereby enables the actuator to operate the rear wheel camber varying mechanism so that the camber of outer and inner rear wheels with respect to a motor vehicle turning direction corresponding to the direction in which the front wheels are steered, is rendered negative and positive, respectively. The rear wheel camber varying mechanism has a wheel supporting member for supporting a rear wheel rotatably thereon, and lower and upper coupling members interconnecting the wheel supporting member and a body of the motor vehicle. The upper coupling member is movable transversely of the motor vehicle body, and the actuator is coupled to a portion of the upper coupling member which is mounted on the motor vehicle body.
