Control interface with haptic feedback using a magnetorheological fluid module

A control interface with haptic feedback for a motor vehicle, configured to take into account an action of a user by providing the user with a haptic feedback, the control interface comprising:

• a magnetorheological fluid module, said magnetorheological fluid module comprising:
• a rotary element comprising a plurality of walls and which rotates about an axis of the magnetorheological fluid module, said rotary element being in contact with a magnetorheological fluid and configured to be coupled to a grip element;
• an application unit for applying a magnetic field to the magnetorheological fluid, and modifying a strength of the magnetic field;
• a processing unit configured to receive a signal emitted by an environmental sensor and to control the application unit for applying a magnetic field according to the signal received;
• and
• a cavity to receive the magnetorheological fluid, wherein a central wall protrudes from the cavity and is arranged between the plurality of walls of the rotary element,
• wherein the environmental sensor is a torque sensor, and
• wherein the grip element is mounted in a pivoting manner in relation to a ring of the rotary element, and the pivoting of the grip element is blocked by the torque sensor arranged between the grip element and the ring of the rotary element.
