Definitions

  • the invention relates to a method for automatically actuating a motor vehicle door, in particular the tailgate of a motor vehicle, from a first to a second end position by means of a drive which comprises an electromagnetic friction clutch which can be actuated by a control device and has an energizable coil.
  • each pivotable part of a vehicle is summarized for closing an opening.
  • the vehicle door can therefore be a side or rear door as well as a tailgate (trunk lid), a bonnet, a roof flap or the like.
  • the tailgate for opening and closing is partially pivoted with full power of the drive into its end positions defined by end stops and the drive is then switched off.
  • the invention has for its object to provide a method by means of which the automatically actuable vehicle door of a motor vehicle is safely pivoted into the desired end position even at extreme temperatures below 0 ° C without excessive stress on the drive units and door hinges.
  • the invention is essentially based on the idea of reducing the excitation current flowing through the coil for actuating the friction clutch as soon as the vehicle door reaches a predetermined switch position lying in front of the respective end position of the vehicle door, so that the vehicle door subsequently moves from it Drive is moved into its end position with a reduced torque transmitted by the friction clutch.
  • the time course of the excitation current through the coil is chosen such that the torque transmitted by the friction clutch is gradually reduced from a maximum value to a predetermined final value. This can take place, for example, through a defined, predetermined ramp-shaped course of the excitation current.
  • a clutch is used as a controllable electromagnetic friction clutch, which comprises an additional elastic element or a permanent magnet, which (r) causes the friction clutch even when the coil is not energized transmits reduced torque, which is selected such that the vehicle door stops in the respective position after the drive is switched off, but manual actuation of the vehicle door is possible.
  • the control device can completely switch off the excitation current flowing through the coil of the friction clutch as soon as the vehicle door reaches the switch position lying in front of the corresponding end position , The vehicle door is then automatically pivoted into its end position by the drive with a reduced torque transmitted by the friction clutch.
  • Fig.l is a schematic view of the rear area of a motor vehicle with opening tailgate and
  • FIG. 2 shows the block diagram of a device for carrying out the method according to the invention.
  • Fig.l 1 denotes a motor vehicle which comprises a tailgate 2.
  • the tailgate 2 can be pivoted from a closed position I into an open end position III (and vice versa) by means of an electromechanical drive 4 acting on the hinge axis 3 of the tailgate 2.
  • the opening process of the tailgate 2 is also supported in a manner known per se by two gas springs 5 arranged laterally on the tailgate 2.
  • the drive 4 comprises an electric motor 6 (optionally with an integrated gear arranged on the output side), which acts on the hinge axis 3 via an electromagnetically actuated friction clutch 7 and a downstream transmission gear 8.
  • Electric motor 6 and friction clutch 7 can be actuated by means of an electronic control device 9, which is also connected to a position sensor 10 which detects the position of the tailgate 2.
  • the friction clutch 7 advantageously has the structure known from DE 102 25 580 AI. It comprises a provided with a friction lining 11 and rotatably connected to a drive shaft 12 rotor part 13 on which on its side facing away from the friction lining 11 an electric coil 14 is arranged, and a rotatably but axially displaceably connected to an output shaft 15 armature disk 16.
  • a permanent magnet 17 is also arranged on the rotor part 13, so that when the coil 14 is not energized, the armature disk 16 is pressed against the friction lining 11 of the rotor part 13 with a force which is large enough for the tailgate 2 in the respective when the friction is switched off -Coupling 7 assumes the position it occupies and the frictional engagement between the armature disk 16 and the friction lining 11 can be overcome with a subsequent manual actuation of the tailgate 2.
  • the tailgate 2 may initially be in its closed position I.
  • the vehicle owner actuates e.g. an appropriate remote control. This acts on the control device 9 via a receiving device (not shown), which then both activates the electric motor 6 and, by energizing the coil 14, causes a maximum transmission of the torque from the drive shaft 12 to the output shaft 15. The tailgate 2 is then opened automatically.
  • the electronic control device 9 detects with the help of the position sensor 10, that the tailgate 2 reaches a predefined position (switch position) which is immediately before the open end position of the tailgate 2, it switches off the excitation current of the coil 14.
  • the friction clutch 7 only transmits a reduced torque caused by the permanent magnet 17 from the drive shaft 12 to the output shaft 15, so that the tailgate 2 is pivoted relatively slowly into the open end position by the continuing electric motor 6 and the gas springs 5. After reaching this position, the electric motor 6 is then switched off by the control device 9.
  • tailgate 2 is to be closed again, the tailgate 2 is closed in a manner corresponding to the opening procedure.
  • the invention is in no way limited to the exemplary embodiment described above. So it can be advantageous not to completely switch off the excitation current of the coil of the friction clutch when the switching position is reached, but to reduce it only gradually, in order to avoid jerky movements of the drive parts or the tailgate caused by a sudden reduction in the torque to be transmitted become.
  • the position sensor need not necessarily be a sensor separate from the drive. Rather, the position sensor can also be integrated in the drive and e.g. To determine the position of the tailgate, evaluate the rotation of the output shaft instead of its swivel angle.
  • the drive does not necessarily have to be connected to the hinge axis of the tailgate, but it can also act, for example, on a hinge bracket connected to the tailgate.

Abstract

L'invention concerne un procédé pour l'actionnement automatique d'une porte de véhicule (2), notamment du hayon d'un véhicule automobile (1), d'une première position finale à une deuxième position finale (I, III) au moyen d'un entraînement (4) qui comprend un embrayage à friction électromagnétique (7) pouvant être actionné par un dispositif de commande (9) et muni d'une bobine (14) pouvant être parcourue par un courant. L'invention vise à ce que la porte de véhicule puisse être amenée de manière sûre dans la position finale désirée, même en cas de températures extrêmes inférieures à 0 °C, sans que les unités d'entraînement et les charnières de porte ne subissent une sollicitation excessive. A cet effet, le courant excitateur s'écoulant à travers la bobine (14) pour l'actionnement de l'embrayage à friction (7) est réduit dès que la porte de véhicule (2) atteint une position de commutation prédéfinie (II), située avant la position finale désirée (I, III) de la porte de véhicule (2), de sorte que la porte de véhicule (2) est ensuite mue par l'entraînement (4) dans sa position finale respective (I, III) avec un couple de rotation réduit transmis par l'embrayage à friction (7).
