Claims (14)

  1. Procédé pour la commande d'une bougie à incandescence dans un moteur diesel dans la phase de préchauffage, dans lequel le gradient temporel d'une grandeur de mesure électrique apparaissant sur la bougie à incandescence en fonction de la température est déterminé par mesurage, le gradient temporel étant comparé avec une valeur seuil et la tension d'alimentation électrique de la bougie à incandescence étant modifiée en cas de dépassement ou de sous-dépassement de la valeur seuil, caractérisé en ce que la valeur seuil est modifiée au cours de la phase de préchauffage.
  2. Procédé selon la revendication 1, caractérisé en ce que le gradient de la résistance électrique de la bougie à incandescence est déterminé.
  3. Procédé selon la revendication 1, caractérisé en ce que le gradient de l'intensité de courant du courant traversant la bougie à incandescence est déterminé.
  4. Procédé selon la revendication 2 ou 3, caractérisé en ce que la tension d'alimentation électrique effective de la bougie à incandescence est réduite lorsque la valeur absolue du gradient dépasse une valeur seuil supérieure.
  5. Procédé selon la revendication 2, 3 ou 4, caractérisé en ce que la tension d'alimentation électrique effective est augmentée lorsque la valeur absolue du gradient tombe en-dessous d'une valeur seuil inférieure.
  6. Procédé selon l'une des revendications précédentes, caractérisé en ce que l'au moins une valeur seuil est modifiée en fonction de la résistance électrique mesurée et/ou en fonction de l'intensité de courant mesurée.
  7. Procédé selon la revendication 6, caractérisé en ce que l'au moins une valeur seuil est modifiée en fonction du temps.
  8. Procédé selon la revendication 6, caractérisé en ce que l'au moins une valeur seuil est modifiée en fonction de l'énergie électrique délivrée progressivement à la bougie à incandescence.
  9. Procédé selon l'une des revendications précédentes, caractérisé en ce que le gradient est déterminé au moins dans la section la plus pentue de la courbe de chauffage de la bougie à incandescence.
  10. Procédé selon l'une des revendications précédentes, caractérisé en ce que le gradient est déterminé à plusieurs reprises au cours de la phase de préchauffage.
  11. Procédé selon la revendication 10, caractérisé en ce que la tension d'alimentation électrique effective pour la bougie à incandescence est obtenue par modulation de largeur d'impulsion à partir de la tension du réseau de bord, et en ce que les instants auxquels les mesures pour la détermination du gradient sont effectuées se situent dans des fenêtres temporelles dans lesquelles la tension d'alimentation est appliquée à la bougie à incandescence.
  12. Procédé selon la revendication 11, caractérisé en ce que les instants auxquels les mesures pour la détermination du gradient sont effectuées sont synchronisés avec la période de la modulation de largeur d'impulsion.
  13. Procédé selon l'une des revendications précédentes, caractérisé en ce que le gradient est réglé sur une valeur de consigne.
  14. Procédé selon l'une des revendications précédentes, caractérisé en ce que l'énergie électrique délivrée à la bougie à incandescence dans la phase de préchauffage est prédéterminée.
