Abstract
A control interface with haptic feedback for a motor vehicle to take into account an action of a user by providing the user with a haptic feedback. The control unit includes a magnetorheological fluid module that has a rotary element which rotates about an axis of the magnetorheological fluid module, said rotary element being in contact with magnetorheological fluid and designed to be coupled to a grip element, and an application unit for applying a magnetic field to the magnetorheological fluid, designed to modify the strength of the magnetic field. The control interface also includes a control unit having a fixed tactile surface arranged at the centre of the grip element.
