Definitions

  • the invention relates to a circuit arrangement for controlling an electrically operated motor vehicle door lock or the like with the features of the preamble of claim 1.
  • the invention relates to a circuit arrangement for controlling an electrically operated motor vehicle door lock or the like, that is to say also suitable for other types of lock on motor vehicles such as locks on rear doors, tailgates or hoods.
  • the known motor vehicle door lock which forms the starting point, has a lock latch and a pawl which holds the lock latch in the closed position and an electromotive auxiliary locking drive. This is switched on after the lock latch has reached a pre-closing position and then transfers the lock latch to the main closed position by means of a motor.
  • the pre-locking position can be the reaching of the pre-locking or a specific position of the motor vehicle door in relation to the body, for example with a remaining gap of 6 mm.
  • a switch which detects the pre-closed position in particular a switch which senses the position of the lock latch, gives a corresponding start signal to the electromotive auxiliary locking drive (DE-A-42 18 177).
  • the circuit arrangement is such that the lock latch is assigned a second switch which detects the closed position in addition to the switch which detects the closed position.
  • this second switch switches off the electromotive auxiliary locking drive.
  • the invention has for its object to provide a circuit arrangement for such a motor vehicle door lock or the like, which is even simpler. This object is achieved by the features of the characterizing part. Advantageous refinements and developments are the subject of the dependent claims.
  • FIG. 1 shows a schematic representation of an example of an electromotive motor vehicle door lock
  • FIG. 3 shows the states of the connections in FIG. 2 in the different operating states
  • Fig. 4 is a circuit diagram.
  • Fig. 1 shows a schematically illustrated embodiment of a motor vehicle door lock or the like. It should be understood that similar structures can also be used for locks on other parts of a motor vehicle body, ie for rear doors, tailgates or hoods.
  • the motor vehicle door lock shown which is therefore intended for the side door of the motor vehicle, first has a lock latch 1 and a pawl 2 holding the lock latch 1 in the closed position.
  • a locking bolt 3 is also indicated as an example of a counter element for the door lock.
  • An electromotive locking auxiliary drive 4 is provided, which in the exemplary embodiment shown has an electric drive motor 5 which drives a worm wheel 7 via a worm 6, which is coupled to a coaxial spur gear 8. Via an intermediate spur gear 9 and a third spur gear 10, an output shaft 11 is moved, which carries a lever 12 at its rear end section. Coaxial to the output shaft 1 1, however separated from it, the pivot axis of the lock latch 1 is arranged.
  • the lever 12 engages behind the lock latch 1 on a driving projection 14.
  • Fig. 1 shows the closed position of the lock latch 1 with the pawl 2 which has fallen into the main catch 13.
  • the pawl 2 can also engage in the preliminary catch 15.
  • the pre-closing position of the lock latch 1 which corresponds, for example, to a body clearance with a remaining gap of 6 mm.
  • the electromotive locking auxiliary drive 4 is switched on after the lock latch 1 has reached the pre-closing position.
  • the lock latch 1 is then transferred by motor to the main closed position, specifically in that the lever 12 pushes the driving projection 14 on the lock latch 1 in front of it until it has reached the closed position shown in FIG. 1 with the pawl 2 engaged.
  • a switch 16 recognizing the pre-closed position, which according to the illustrated and thus preferred example is a lock latch switch scanning the position of the lock latch 1.
  • it is an electromechanical microswitch, the switching plunger of which is actuated via a cam 17 on the lock latch 1.
  • Contactless actuable switches for example with Hall sensors etc., are also known from the prior art.
  • the motor vehicle door lock shown in FIG. 1 is one in which the locking auxiliary drive 4 is automatically decoupled from the lock latch 1 when the locking power drive 4 is switched off or the drive energy fails.
  • This can be achieved in that the auxiliary locking drive 4 is reset to its initial position when the drive motor 5 is de-energized by a spring, but this can also be achieved by an electromagnetic clutch in the auxiliary locking drive 4, which is disengaged at the appropriate moment.
  • the latter has the further advantage that an emergency interruption of the power chain can be achieved while the drive is running.
  • Fig. 2 shows the extremely simple circuit arrangement for controlling the electrically operated motor vehicle door lock shown as an example in Fig. 1.
  • the negative pole 18 of the auxiliary locking drive 4 or the electric drive motor 5 of the auxiliary locking drive 4 is connected to ground or negative potential and the positive pole 19 is connected and is either at the positive potential of the vehicle electrical system voltage or is at ground or is open (floated).
  • the switch 16 is between ground and a switching connection 20.
  • the previously mentioned, optionally available electromagnetic clutch 21 is also entered, without this having to be explained further here.
  • the illustrated embodiment shows that the switch 16 is designed as a closer, that is, closes when the pre-closing position is reached and connects the switching connection 20 to ground.
  • Fig. 1 makes it clear that the switch 16 in the illustrated and in this respect preferred embodiment switches back when the closed position of the lock latch 1, but preferably as shown when reaching a slightly beyond the closed position overtravel position of the lock latch 1.
  • a continuous control curve 17 can control the switch 16, as in the exemplary embodiment shown.
  • the switch 16 can also be controlled by two switching pulses and maintain its switching state between the switching pulses. This is a control technology that can be used for contactless switches.
  • the auxiliary locking drive 4 automatically switches off when the closed position of the lock latch 1 is reached, in particular when the overstroke position of the lock latch 1 is somewhat beyond the closed position, that is to say in particular the positive pole 19 of the auxiliary lock drive 4 then to ground or negative potential is or is open.
  • the criterion for switching off the auxiliary locking drive 4 when the locking position is reached is the current consumption of the auxiliary locking drive 4.
  • the switch 16 switches back when the overtravel position of the lock latch 1 is reached and switches on again when the lock latch 1 reaches the closed position without a renewed switching operation taking place at the positive pole 19 of the auxiliary locking drive 4. This corresponds to the above-mentioned Imaging Logo ⁇ by the solid control curve 17th
  • FIG. 3 shows, for the illustrated and preferred exemplary embodiment, the potentials at the connections 18, 19, 20 as at the negative pole 18, at the positive pole 19 and at the switching connection 20, for the various phases of actuation of the motor vehicle door lock.
  • the potential curve at the switching connection 20 and the positive pole 19 is accordingly shown in FIG. 4.

Abstract

L'invention concerne un circuit pour commander une serrure de portière de véhicule à moteur, actionnée électriquement, ou similaire. Cette serrure comprend un loquet (1), un cliquet (2) maintenant le loquet (1) en position fermée, ainsi qu'un élément d'entraînement auxiliaire de fermeture (4), commandé par un moteur électrique, qui est mis en marche, une fois le loquet (1) en position de préfermeture, et qui fait ensuite passer le loquet (1) en position de fermeture principale, au moyen du moteur. Il est prévu un commutateur (16) qui détecte la position de préfermeture, notamment un commutateur qui détecte la position du loquet (1). Le circuit de l'invention est conçu de manière particulièrement simple car le pôle négatif (18) de l'élément d'entraînement auxiliaire de fermeture (4) est toujours relié à la masse ou à un potentiel négatif, et le pôle positif (19) est commuté, et raccordé soit au potentiel positif de la tension du réseau de bord, soit à la masse ou à un potentiel négatif, ou bien il est ouvert. De plus, il est prévu un seul commutateur (16), qui est situé entre la masse et une borne de connexion (20), et provoque une commutation de l'élément d'entraînement auxiliaire de fermeture (4). De façon particulièrement appropriée, cet élément d'entraînement auxiliaire de fermeture (4) est mis automatiquement hors circuit lorsque le loquet (1) atteint sa position de fermeture, notamment lorsqu'il atteint une position de course excessive située légèrement au-delà de la position de fermeture, c'est-à-dire lorsque notamment le pôle positif (19) de l'élément d'entraînement auxiliaire de fermeture (4) est raccordé à la masse ou à un potentiel négatif, ou bien est ouvert. Ceci s'applique en particulier, lorsque le critère pour la mise hors circuit de l'élément d'entraînement auxiliaire de fermeture (4), lorsque le loquet (1) atteint sa position de fermeture, notamment lorsqu'il atteint la position de course excessive située légèrement au-delà de la position de fermeture, est la consommation de courant de l'élément d'entraînement auxiliaire de fermeture (4).
