Abstract

The invention relates to a motor vehicle door and to a method for acting on said motor vehicle door in terms of braking/holding or pulling closed/opening. The motor vehicle door is equipped with a driven (4, 5; 4) door leaf (1), a magnetic arrangement (4) as component of the drive (4, 5; 4) and at least one sensor (6) assigned to the door leaf (1). According to the invention, on the basis of a speed and/or position of the door leaf (1) with respect to a motor vehicle body (2) detected by means of the sensor (6), the magnetic arrangement (4) is supplied with power by a control unit (7) for either braking or holding, or pulling closed or opening the door leaf (1).

Claims

1. Motor vehicle door equipped with a door leaf (1) and a drive (4;

4, 5), as well as a magnetic arrangement (4) as part of the drive (4;

4, 5) and with at least one sensor (6) assigned to the door leaf (1), characterised in that, depending on the speed and/or position of the door leaf (1) in relation to a motor vehicle body (2) determined with the aid of the sensor (6), the magnetic arrangement (4) for selectively braking, holding, pulling closed or opening the door leaf (1) is energised by a control unit (7).

2. Motor vehicle door according to claim 1, characterised in that the sensor (6) is designed as a speed/position sensor.

3. Motor vehicle door according to claim 2, characterised in that the sensor (6) is a step counter (6).

4. Motor vehicle door according to claim 3, characterised in that the magnetic arrangement (4) contains at last two electric solenoids (4) and, where applicable, permanent magnets (5).

5. Motor vehicle door according to claim 4, characterised in that the two electric solenoids (4) are selectively energised in the sense of mutual repelling, mutual attracting and in the sense of a repelling/attracting of the additional permanent magnets (5).

6. Motor vehicle door according to claim 5, characterised in that the magnetic arrangement (4) is energised in accordance with signals of the sensor (6) processed in the control unit (7) in the sense of a control.

15. Motor vehicle door according to claim 1, characterised in that the magnetic arrangement (4) contains at last two electric solenoids (4) and, where applicable, permanent magnets (5).

16. Motor vehicle door according to claim 2, characterised in that the magnetic arrangement (4) contains at last two electric solenoids (4) and, where applicable, permanent magnets (5).

17. Motor vehicle door according to claim 1, characterised in that the magnetic arrangement (4) is energised in accordance with signals of the sensor (6) processed in the control unit (7) in the sense of a control.

18. Motor vehicle door according to claim 2, characterised in that the magnetic arrangement (4) is energised in accordance with signals of the sensor (6) processed in the control unit (7) in the sense of a control.

19. Motor vehicle door according to claim 3, characterised in that the magnetic arrangement (4) is energised in accordance with signals of the sensor (6) processed in the control unit (7) in the sense of a control.

7. Method for acting on a door leaf (1) of a motor vehicle door in the sense of braking/holding or closing/opening, in which the motor vehicle door contains a door leaf (1) with a drive (4;

4, 5), as well as a magnetic arrangement (4) as part of said drive (4, 5;

4) and at least a sensor (6) assigned to the door leaf (1), in which the sensor (6) determines the speed and position of the door leaf (1) in relation to a motor vehicle body (2) and transfers this to a control unit (7), after which the control unit (7), depending on the signals of the sensor (6), energises the magnetic arrangement (4) in such a way that the door leaf (1) is selectively braked, held, or pulled closed, opened or pushed out.

8. Method according to claim 7, characterised in that the sensor (6) detects the speed and position of the door leaf (1) in relation to the motor vehicle body (2) and transfers this information to the control unit (7).

9. Method according to claim 8, characterised in that according to the position and speed of the door leaf (1) in relation to the motor vehicle body (2), the control unit (7) acts on the magnetic arrangement (4) in the sense of braking/holding or closing/opening.

10. Method according to claim 9, characterised in that the control unit (7) also processes and implements an operator request relating to the position and/or movement of the door leaf (1).

11. Method according to claim 7, characterised in that the control unit (7) also processes and implements an operator request relating to the position and/or movement of the door leaf (1).

12. Method according to claim 8, characterised in that the control unit (7) also processes and implements an operator request relating to the position and/or movement of the door leaf (1).

13. Method according to claim 7, characterised in that according to the position and speed of the door leaf (1) in relation to the motor vehicle body (2), the control unit (7) acts on the magnetic arrangement (4) in the sense of braking/holding or closing/opening.

14. Method according to claim 13, characterised in that the control unit (7) also processes and implements an operator request relating to the position and/or movement of the door leaf (1).
