Abstract

L'invention concerne un procédé de détermination d’un indicateur de cliquetis de la combustion d’un moteur à combustion interne comprenant au moins un capteur accélérométrique. On construit (MOD) au préalable un modèle d'indicateur du cliquetis en fonction d'une accélération du moteur en entrainant un réseau de neurones convolutif sur une base d'apprentissage construite au moyen du moteur comportant en outre un capteur de pression, et selon les étapes suivantes: (i) pour une pluralité de cycles du moteur, on mesure un signal d'accélération et un signal de pression ; (ii) on détermine, pour chaque cycle du moteur, un indicateur de cliquetis à partir du signal de pression, et on constitue la base d'apprentissage en associant un indicateur de cliquetis au signal d'accélération correspondant. Puis, on mesure (MES) un signal d'accélération et on détermine (IND) l'indicateur de cliquetis à partir du signal d'accélération et du modèle d'indicateur du cliquetis en fonction d'une accélération.
