Abstract

L’invention concerne un procédé d’anticipation d’une apparition d’une combustion lisse dans un moteur thermique. Une plage angulaire (F) de détection est partagée en plusieurs intervalles (I) avec une identification de l’intervalle (Iid) dans lequel le phénomène de pré-allumage est détecté, l’intervalle identifié (Iid) étant localisé par rapport à la borne inférieure (Bi) de la plage ou par rapport à au moins un intervalle précédent pour lequel un phénomène de pré-allumage avait été précédemment détecté. Quand un premier incrément, représentatif de la localisation de l’intervalle identifié (Iid) par rapport à la borne inférieure (Bi) et augmentant en proximité de la borne inférieure (Bi), est supérieur à un premier seuil d’incrémentation ou quand un deuxième incrément, augmentant plus une différence de distance de la borne inférieure (Bi) entre l’intervalle précédent et l’intervalle identifié (Iid) est grande, est supérieur à un deuxième seuil d’incrémentation, il est anticipé une apparition de combustion lisse.
