Abstract

Procédé de contrôle moteur d’un véhicule comportant un moteur (1) à combustion interne, comprenant les étapes suivantes : déterminer l’accélération instantanée du vilebrequin à partir du signal de position du vilebrequin, par plages de temps du cycle moteur de chaque cylindre ou groupes de cylindres, compresser les données issues de la détermination de ladite accélération instantanée selon un procédé de compression utilisant une base orthogonale, adresser les données compressées d’accélération instantanée du vilebrequin à un réseau de neurones afin que ce dernier détermine en résultats un indicateur de qualité de combustion, adresser l’indicateur de qualité de combustion à une unité (10) de contrôle moteur afin qu’elle modifie en fonction de celui-ci les commandes transmises aux actuateurs du moteur, dans le but de minimiser la consommation spécifique de carburant et les polluants pour une même commande de couple.
