Method of controlling a movement of a door with a controllable rotary damper

A method for influencing a movement of a passenger door of a vehicle, the method comprising:

• providing a door component having a controllable damper device and two attachment units that are movable relative to one another;
• providing two spindle units that are in engagement with one another and disposed between the two attachment units;
• providing a sensor and using the sensor to determine a position of the passenger door relative to the vehicle;
• and
• controlling a movement of the passenger door at least partially between a closed position and an open position by a controlled actuation of a damper device and a motor for driving one of the spindle units with reference to the relative position of the door determined by the sensor, to thereby achieve a guided door movement;
• and
• wherein one of said two attachment units is connected to a supporting structure and another of the two attachment units is connected to the door, the spindle units are a threaded spindle and a spindle nut, respectively, and the method comprises influencing a rotation of one of the spindle units with a magnetorheological transmission apparatus in order to influence the movement of the door, and wherein an annular cylindrical cavity is formed radially between a coupling rod and one of the spindle units, and the magnetorheological transmission apparatus is disposed in the cylindrical cavity.
