Abstract
A motor vehicle steering mechanism is provided and includes a steering wheel fixedly connected to a steering column, a steering pinion meshing with a rack, a planetary gear system connected to the steering column and the steering pinion, wherein during a normal trouble-free driving operation the housing of the gear system is freely rotatable; an angle sensor detects the position of the steering column and/or steering wheel and generates a signal representative thereof. wherein a first drive applies torque directly to the steering column, and a second drive acts on the steering pinion or rack. The signal from the angle sensor is an input signal for an electronic control system that controls the second drive. A torque adjuster controls the first drive such that a hand torque corresponding to a driving situation is Produced for achieving a defined driving sensation for the driver on the steering wheel.

13. A motor vehicle steering mechanism, comprising:
-
a steering wheel fixedly connected to a steering column;
a steering pinion that meshes with a rack;
a planetary gear system having an input side connected to said steering column and an output side connected to said steering pinion, wherein said planetary gear system has a housing that during a normal trouble-free driving operation is freely rotatable;
an angle sensor for detecting the position of at least one of said steering column and said steering wheel and for generating a signal representative of such position;
a first drive for direct application of torque to said steering column;
a second drive for acting on said steering pinion or said rack;
an electronic control system for controlling said second drive, wherein a signal from said angle sensor is an input signal for said control system; and
a control means for controlling said first drive such that a hand torque corresponding to a driving situation is produced for achieving a defined driving sensation for a driver on said steering wheel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
