Steering system for motor vehicle.

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].
