Abstract

La présente invention a pour objet un procédé pour gérer du cliquetis dans un cylindre d'un moteur à combustion interne, dans un système comprenant au moins un capteur acoustique (2) et un calculateur (1), pour prendre en compte une pollution acoustique provenant d'un bruit parasite (5), le procédé comprenant : - mettre en forme et numériser (82) les signaux (20) du capteur, - appliquer un filtre passe bande (84) pour obtenir un bruit filtré (24), - déterminer une fonction de correction (86) à gain ajustable utilisant une courbe de correction de gain (7), et déterminer, en fonction de la position angulaire de fin d'injection, le point de courbe de correction de gain à utiliser pour transformer le bruit filtré en score de cliquetis corrigé, - comparer (88) un score de cliquetis corrigé ainsi obtenu à un seuil de décision de cliquetis, pour corriger l'avance d'allumage, - la courbe de correction de gain étant définie par une valeur de calibration (Gin) et quatre points angulaires (A, B, C, D), les quatre points angulaires étant obtenus par calcul, à partir des positions de début et fin (WS1, WS2) de la fenêtre d'observation de cliquetis et au moins d'une caractéristique connue du bruit.
