  • Each actuator is assigned an electrical changeover switch, the movable contact of which is connected to ground and which, depending on whether the vehicle door is locked or unlocked, acts on one or the other of two outputs of the switch, with corresponding outputs of all switches being brought together and with the central control unit are connected.
  • Each switch is both manual

  • a Stellvorga ⁇ g is initiated as soon as the movable contact of any of the electrical switches is changed over by hand and acts on the other contact. All electric motors start to turn and switch the movable contacts of the other switches so that all switches are in the same state again at the end of the actuating process. This applies if the system works normally. If an electrical switch remains in the starting position due to a malfunction, this is recognized by the central control unit as a malfunction, since after the end of the control pulse both inputs are still connected to ground. The fault can then be indicated optically or acoustically.

  • Other control units in a door for example for an electric window lifter or an electrically adjustable exterior mirror, can also be connected to the central control unit via this line.
  • Whether a door is locked is monitored according to claim 5 in that the arrival of the movable transmitter element in the rest position corresponding to a locked door can be detected by the central control unit and / or peripheral control unit. This seems cheaper than if one detects leaving the other rest position. Leaving the other rest position only means that the electric motors have started to turn, but not yet that the locking members have also reached their other end position. An electric motor may have stopped earlier due to a defect.

If the central control unit detects the locking of all doors, it can briefly control an optical or acoustic display.

Abstract

Un dispositif de verrouillage central de type connu comporte plusieurs organes de positionnement pourvus d'un moteur électrique dont le sens de rotation peut, en particulier, être inversé et au moyen duquel un membre de verrouillage peut être déplacé entre deux positions terminales. Ce dispositif de verrouillage central comporte en outre au moins un capteur, chaque capteur étant associé à un autre capteur et étant pourvu d'un élément de capteur mobile qui, lorsque le membre de verrouillage est dans la première position terminale, se trouve dans une première position de repos et, lorsque le membre de verrouillage est dans la deuxième position terminale, se trouve dans une deuxième position de repos, et qui peut être déplacé manuellement ou par le moteur électrique de l'organe de positionnement concerné. Une unité centrale de commande met en marche les moteurs électriques des organes de positionnement en fonction du déplacement d'un élément de capteur. Pour qu'il soit plus facile de déclencher avec la main un signal de mise en marche et afin de réduire l'usure d'un accouplement se trouvant éventuellement dans l'organe de positionnement, les moteurs électriques peuvent déjà être mis en route lorsque l'élément de capteur quitte une position de repos et non pas seulement au moment où l'élément de capteur arrive dans son autre position de repos.
