摘要： According to the invention, there is provided is a vehicle steering system which can improve the resistance of a vehicle against external disturbances such as crosswind, and can prevent the operability of the steering system from being seriously affected by a failure in a part of the system related to the generation of steering reaction such as a lateral acceleration sensor, a yaw rate sensor or a reaction control unit.

Therefore, a fail-safe feature can be obtained, and unnecessary loss of the operability of the steering system can be avoided. By reducing the assisting steering torque from the normal level, which is effective when the sensors are operating normally, at such a time, the driveability of the steering system similar to that under the normal condition can be ensured.

摘要： In a vehicle steering control system, a manual steering input is assisted by a powered actuating steering torque which is given by K( gamma -tdxd gamma /dt), where y is a detected yaw rate, K and td are coefficients which depend on a vehicle speed, and d/dt denotes a time derivative. The detected yaw rate contributes to reducing the yaw rate of the vehicle. In particular, the coefficient td is positive in value in a low speed range, and substantially linearly decreases with the vehicle speed, becoming negative at a certain intermediate vehicle speed. Thus, in a high speed range, when the vehicle is steered in one direction either by external disturbances or by a manual steering input, the detected yaw rate and the change rate of the yaw rate both contribute to the reduction of the yaw rate. However, in a low speed range, when the vehicle is steered in one direction, the detected yaw rate contributes to the reduction of the yaw rate but the change rate of the yaw rate contributes to the increase of the yaw rate. Thus, in a high speed range, the vehicle is made highly immune against external disturbances and the effort required for the manual steering of the vehicle is increased with the increase in the change rate of the yaw rate. Conversely, in a low speed range, the stability of the vehicle is of no concern, and the effort required for the manual steering of the vehicle is decreased with the increase in the change rate of the yaw rate.

摘要： In a vehicle steering control system, an actuating torque is applied to steerable wheels according to a steering torque applied to a steering wheel in a conventional manner, and an additional actuating torque is applied to the steering wheel by an electric motor according to lateral dynamic conditions of the vehicle so as to control the lateral stability of the vehicle even in the presence of external interferences such as crosswind. Such external interferences are detected as a lateral dynamic condition of the vehicle such as the yaw rate of the vehicle, and the steering control system produces a steering reaction which counteracts such a lateral dynamic condition by applying the additional actuating torque to the steerable wheels so that the vehicle may maintain a straight course in spite of such external interferences without requiring any intentional efforts by the vehicle operator. In particular, by suppressing the additional actuating torque in an understeer condition, the handling of the vehicle can be improved.

摘要： A motor vehicle steering system has a yaw rate sensor for detecting a yaw rate of a motor vehicle, and a lateral acceleration sensor for detecting a lateral acceleration of the motor vehicle. The detected yaw rate and lateral acceleration are processed according to predetermined functions to determine a control signal, which is applied to a motor to turn a steering wheel. Road wheels are correspondingly steered through a steering mechanism in a direction to suppress a disturbant motor vehicle behavior that is caused by the yaw rate and the lateral acceleration.

摘要： The steering is applied via a manually controlled torque. A servo steering system (10) applies a servo torque to correct for external influences on the steering. These comprise slewing forces, detected by slew sensors and power steer. The latter is corrected by monitoring the driving torque on the steered wheels and the vehicle speed. The steering reaction force generated by the slew forces and by the power steer are computed and used to generate the correction signals for the servo steering. The correction force varies in relation to the vehicle speed and the levels of the outside forces. For small traction forces the correction is low.

摘要： A steering system [10] for a motor vehicle having power steering means [PS] including an actuator for turning steerable road wheels of the motor vehicle includes a control mechanism [PS] for eliminating a deviation [ theta e] between a desired direction [ theta s; K. theta s] of travel of the motor vehicle and an actual direction [ psi ; Kn. psi ] of travel of the motor vehicle, based on an output signal from a direction indicating mechanism [11, 13] which indicates the desired direction [ theta s; K. theta s] and an output signal from a direction detecting mechanism [17, 15] which detects the actual direction [ psi ; Kn. psi ]. The control mechanism [15] determines a target turning angle [Ks. theta e] for the steerable road wheels dependent on the deviation [ theta e] between the desired direction [K. theta s] and the actual direction [Kn. psi ], and controls the power steering mechanism [PS] to turn the steerable road wheels up to the target turning angle [Ks. theta e].

摘要： The steering has a manually applied torque as well as a correction torque to counteract slew forces on the vehicle. The slew correction reduces the steering torque by an amt. dependent on the measured slew force, the rate of change of slew force and the actual vehicle speed. At low speeds there is a positive increase in the steering torque. The steering torque correction is a function of the slew force minus a speed related coefft. multiplies by the rate of change of slew force. The coefft. is positive for higher speeds and negative for low speeds.
