An input device, in particular joystick, with an operating device and a magnetorheological brake device and a controller for activating the brake device. The operating device includes a supporting structure and an operating lever, which is accommodated on the supporting structure for pivoting around at least one pivot axis. The brake device is coupled with the pivot axis for controlled damping of a pivoting motion of the operating lever by way of the controller.

A magnetorheological transmission device and a method for influencing the coupling intensity of two components, which can be coupled and whose coupling intensity can be influenced. To influence the coupling intensity, a channel is provided, which contains a magnetorheological medium with magnetically polarizable particles. A magnetic field generating unit generates a magnetic field in the channel in order to influence the magnetorheological medium in the channel. An outer component encloses an inner component. At least one of the two components is mounted via a separate bearing. A distance between the outer and inner components is at least 10 times as great as a typical mean diameter of the magnetically polarizable particles in the magnetorheological medium. The magnetic field of the magnetic field generating unit can be applied to the channel in order to selectively chain together the particles and/or release them.

Vehicles and steering systems for vehicles are provided. An exemplary steering system is provided for an automotive vehicle that includes road wheels and a rack mechanically coupled to the road wheels and laterally displaceable to change an orientation of the road wheels. The steering system includes a steering wheel mounted on a steering column and rotatable by a driver for inputting a steering command. The steering system also includes a lower column coupled to the rack. In the steering system, lateral displacement of the rack causes a rotational torque on the lower column. The steering system further includes a magneto-rheological coupling interconnected between the steering column and the lower column. The magneto-rheological coupling selectively communicates a desired portion of the rotational torque on the lower column to the steering column to provide haptic feedback to the steering column.

Electronic devices, such as consumer electronics devices and control systems in vehicles are controlled by way of a haptic operating device with a rotating unit. Selectable menu items are displayed on a display unit, and a menu item is selected by rotating the rotating unit. The rotating unit latches at a number of haptically perceptible latching points during rotation. The number and rotational position of the haptically perceptible latching points is dynamically changed in accordance with a specific menu item selected by the user.
