Abstract

Dans un système de commande d'allumage, une unité de commande de courant primaire (314) réalise une commande de génération de décharge une ou plusieurs fois pendant un seul cycle de combustion pour permettre à une bougie d'allumage de générer une étincelle de décharge. Une unité de calcul de paramètre (314) calcule successivement un paramètre corrélé à l'énergie d'une étincelle de décharge. Une unité de calcul de densité d'énergie (314) calcule successivement une densité d'énergie par unité de longueur de l'étincelle de décharge. Lorsque la densité d'énergie est plus grande qu'une valeur prédéterminée pendant une période prédéterminée après qu'un courant primaire est interrompu pendant un seul cycle de combustion, une unité de calcul de valeur intégrée (314) calcule une valeur intégrée en intégrant le paramètre pendant la période prédéterminée. La commande de génération de décharge est réalisée à nouveau lorsque la valeur intégrée est inférieure à un seuil de détermination prédéterminé.
