Motor vehicle steering system
First Claim
1. A control appliance, comprising a manually actuated handling device, control elements, a drive connection for operatively connecting the handling device and the control elements wherein the drive connection includes an input part and an output part, an automatically controllable motorized drive appliance selectively connectible to the control elements and operable to selectively actuate the control elements autonomously, wherein the drive appliance is operatively configured and arranged to one of actively adjust the output part and subject the outpart part to a torque and, only during an intervention in normal steering control, to overcome a self-locking device effecting a connection between the input part and the output part during the normal steering control, thereby to effect a disconnection of the input part from the output part during the intervention, which disconnection is otherwise prevented by the self-locking device when the drive appliance is separated from an associated energy supply during the normal steering control such that a permanently effective positive connection between the input part and the output part is selectively and effectively separated.

Abstract
A control appliance for a motor vehicle steering system provides automatic control intervention (or steering intervention) without corresponding movement of the steering wheel. To this end, the drive connection between the steering wheel and the steered vehicle wheels can, in effect, be separated. The automatic control can be either a closed-loop control or an open-loop control.
