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. Figure 6 à publierThe invention relates to a method for determining a knock indicator of the combustion of an internal combustion engine comprising at least one accelerometer sensor. A knock indicator model is built (MOD) beforehand as a function of an acceleration of the engine by training a convolutional neural network on a learning base built by means of the engine further comprising a pressure sensor, and according to the following steps: (i) for a plurality of engine cycles, an acceleration signal and a pressure signal are measured; (ii) a knock indicator is determined for each engine cycle from the pressure signal, and the learning base is formed by associating a knock indicator with the corresponding acceleration signal. Then, an acceleration signal is measured (MES) and the knock indicator is determined (IND) from the acceleration signal and the knock indicator model as a function of an acceleration.
