Claim 23:
24. An input apparatus, comprising:
an operator control device, a magnetorheological brake device, and a control device for controlling said brake device;
said operator control device including a support and an operator control lever pivotably held on said support about at least one pivot axis; and
at least one sensor for sensing a pivot angle of said operator control lever;
said brake device being configured to dampen a pivoting movement of said operator control lever about said pivot axis under control by said control device;
said control device being configured to control said brake device in dependence on a control command and to convert the control command into a haptic signal that is perceptible at said operator control lever to provide a user of the input apparatus with haptic feedback (force feedback) as a consequence of an input that is being performed or that has been performed; and
said brake device being coupled to a pivot axle of said operator control lever via a transmission stage and the transmission stage having a speed ratio between 2:1 and 5:1.
