    Abstract: A steering control apparatus prevents interference between a steering operation of a driver and a steering control operation of the steering control apparatus by detecting a steering operation so as to decrease an amount of the steering control operation when the steering operation is performed by the driver. A guide line provided on a vehicle moving lane on which the vehicle is moving is recognized so as to set a target position on the vehicle moving lane based on a result of recognition of the guide line. A steering control operation is performed so that the vehicle moves to trace the target position. An amount of each component of a steering operation applied to a steering wheel is detected by a steering angle sensor and a steering torque sensor. An amount of the steering control operation is corrected so that the amount of the steering control operation is decreased in accordance with the amount of each component of the steering operation.

    Abstract: A system for controlling steering of a vehicle, including an electric motor used for power-steering torque assist control. The system has an navigation system whose output is used to correct the detected steering angle input by the vehicle driver. A desired yaw rate is determined based on the corrected steering angle and the detected vehicle speed using a yaw rate model, thereby enabling to conduct the aforesaid lane-keeping-steering torque assist control in a more appropriate manner. Further, if the vehicle driver expresses a positive intention to steer the vehicle by himself, for example, so as to avoid an obstacle present on the road, the control is discontinue to meet the wishes of the vehicle driver. Furthermore, the system monitors the steering of the vehicle driver to prevent the vehicle driver from relying upon this steering assist control to an excessive extent.

    Abstract: A method of steering road vehicles having front-wheel and rear-wheel steering is provided in which by an integrating feedback of a measured yaw rate signal to the front-wheel steering the yaw motion is decoupled from the lateral motion of the front axle, the problem of steering thereby being split into two subproblems to be solved separately, that is into a lateral track guiding of the front axle by a signal which a driver generates with the steering wheel, and into an automatic control of the yaw motion, and the eigenvalues of the yaw motion can be shifted as desired by feedback of the measured yaw rate signal to the rear-wheel steering in such a manner that the choice of the yaw eigenvalues has no influence on the steering transfer function from the steering wheel to the lateral motion of the front axle.When employing the steering method according to the invention the driver no longer has to worry at all about the yaw motion of his vehicle; it is stable. Furthermore, via the rear-wheel steering eigenvalues of the yaw motion can be fixed as desired in adaption to the desired driving mode, such as sporting or comfortable.
