Detecting an individual single track value in a vehicle is important to compensate for manufacturing and assembly tolerances that occur in the production of automobiles. These manufacturing and assembly tolerances occur in a different length Ritzelweg to the meshing. The Ritzelweg can for example have tolerances of 1 to 5 mm. This results in different Einspurzeitn due to the manufacturing and assembly tolerances, which can be compensated according to the invention by detecting the at least one Einspurwerts.

L’invention concerne un procédé et une commande pour un dispositif de démarrage (1) comprenant un démarreur (2), un dispositif d’engrènement et un pignon de démarreur (3) destiné à s’engrener dans une couronne dentée (6) d’un moteur à combustion interne (7) d’un véhicule automobile. Le dispositif d’engrènement est actionné par la commande de manière à s’engrener avec le pignon de démarreur (3), en particulier pour une stratégie de fonctionnement marche/arrêt. L’invention vise à améliorer le confort du véhicule, en permettant un redémarrage du moteur à combustion interne (16) nettement plus rapide. A cet effet, au moins une valeur d’engrènement du dispositif d’engrènement est détectée au moyen d’un dispositif de détection (20) afin de permettre l’engrènement du pignon de démarreur (3) et est enregistrée et désignée comme valeur de référence dans la commande.

Claims (10)

  1. Procédé utilisé dans un élément de commande d'un dispositif de démarrage (1) équipé d'un moteur de démarreur (2), d'un dispositif d'enclenchement et d'un pignon de démarreur (3) pour l'enclenchement dans une couronne dentée (6) d'un moteur à combustion interne (7) dans un véhicule automobile, le dispositif d'enclenchement étant commandé pour enclencher le pignon de démarreur (3) de l'élément de commande, au moins une valeur d'enclenchement du dispositif d'enclenchement étant détectée pour enclencher le pignon de démarreur (3) à l'aide d'un dispositif de détection (20), mémorisée et exploitée comme valeur de référence dans l'élément de commande, la valeur de référence mémorisée étant ensuite exploitée pour décaler le moment du début de l'enclenchement à l'aide du dispositif d'enclenchement en fonction de la valeur de référence mémorisée, pour s'enclencher à temps, caractérisé en ce que le dispositif d'enclenchement prend la forme d'un relais de démarreur (4) équipé de deux bobinages pouvant être alimentés séparément en courant, au moins un premier bobinage prenant la forme d'un bobinage d'enclenchement (10) et lors de l'enclenchement, le dispositif de détection (20) mesurant une tension induite (UII) dans le deuxième bobinage non alimenté en courant.
  2. Procédé selon la revendication 1, caractérisé en ce que la valeur d'enclenchement est mesurée par le dispositif de détection dans lequel le pignon de démarreur (3) forme une position dent sur dent lors de l'enclenchement avec la couronne dentée (6).
  3. Procédé selon la revendication 1 ou 2, caractérisé en ce que la valeur d'enclenchement est mesurée sous la forme d'une durée courant jusqu'à l'enclenchement du pignon de démarreur (3).
  4. Procédé selon l'une quelconque des revendications 1 à 3, caractérisé en ce que la valeur d'enclenchement est mesurée sous la forme d'une distance parcourue du pignon de démarreur (3).
  5. Procédé selon l'une quelconque des revendications 1 à 4, caractérisé en ce que le dispositif d'enclenchement prend la forme d'un relais de démarreur (4), le pignon de démarreur (3) étant enclenché à l'aide d'un bobinage du relais de démarreur (4) pouvant être alimenté en courant et un courant du relais de démarreur (4) étant détecté et exploité, ledit courant étant influencé par le mouvement de l'ancre (24) dans le relais de démarreur (4).
  6. Procédé selon l'une quelconque des revendications 1 à 5, caractérisé en ce que la durée courant avant la mise en marche du véhicule est mesurée.
  7. Procédé selon l'une quelconque des revendications 1 à 6, caractérisé en ce que la durée est mesurée par l'élément de commande selon des cycles prédéfinis et que la valeur de référence est actualisée.
  8. Produit de programme informatique pouvant être chargé dans une mémoire de programme (17) par le biais d'ordres de programme, pour exécuter toutes les étapes d'un procédé selon au moins l'une quelconque des revendications 1 à 7 lorsque le programme est exécuté dans un élément de commande.
  9. Élément de commande pour un dispositif de démarrage (1) équipé d'un moteur de démarreur (2), d'un relais de démarreur (4) et d'un pignon de démarreur (3) pour démarrer un moteur à combustion interne (7) dans un véhicule, l'élément de commande étant constitué d'un micro-ordinateur (15) à l'aide duquel une stratégie de fonctionnement par départ-arrêt peut être mise en place, caractérisé en ce que l'élément de commande comporte une mémoire de programme (17) et un dispositif de détection (20) à l'aide duquel les valeurs de tension caractéristiques obtenues dans le deuxième bobinage non alimenté en courant sont mesurables au niveau du relais de démarrage (4) constitué de deux bobinages pouvant être alimentés séparément en courant lors de l'alimentation d'un bobinage à enclencher, ces valeurs de tension pouvant être exploitées sous la forme de valeurs d'enclenchement et être mémorisées dans la mémoire de programme (17) pour leur traitement ultérieur.
  10. Élément de commande selon la revendication 9, équipé d'une mémoire de programme (17), caractérisé en ce que l'élément de commande comporte une mémoire de programme (17) dans laquelle un produit de programme informatique selon la revendication 8 peut être chargé, pour exécuter de façon préférée le procédé selon l'une quelconque des revendications 1 à 7.
