Abstract:
A steering system for a vehicle, comprising:a manually operated steering operation device; an operating moment sensor coupled to the steering operation device and generating a first signal corresponding to an operating moment exercised on the steering operation device; a control unit receiving the first signal generated by the operating moment sensor and emitting a second signal corresponding to an assigned desired steering moment or an assigned desired steering force; a steering device coupled to steerable wheels and mechanically uncoupled from the steering operation device, receiving the second signal corresponding to the assigned desired steering moment or the assigned desired steering force from the control unit and operating the steerable wheels so that the assigned desired steering moment or the assigned desired steering force is set at the steerable wheels; a steering angle sensor coupled to the steerable wheels and supplying a third signal corresponding to an alignment of the steerable wheels to the control unit which, in turn, determines a pertaining desired angle of the steering operation device and generates a corresponding fourth signal; and a feedback unit coupled to the steering operation device, receiving the fourth signal corresponding to the desired angle of the steering operation device and outputting a fifth signal as a function of said fourth signal corresponding to the desired angle of the steering operation device to operate the steering operation device so that the desired angle is set at the steering operation device.
