Abstract

Procédé de commande d’un moteur à combustion interne muni d’un capteur de position du vilebrequin, d’un capteur de pression d’air admis et d’un papillon d’admission d’air frais, comprenant les étapes suivantes : on détermine la vitesse de rotation du moteur à combustion interne en fonction de la dérivée de la position du vilebrequin par rapport au temps,on détermine la pression d’air admis pour une première position du vilebrequin correspondant à 180° avant le point mort haut combustion,on détermine la pression d’air admis pour une deuxième position du vilebrequin correspondant à 390° avant le point mort haut combustion,on détermine un seuil de pression d’apprentissage de la pression atmosphérique en fonction de la vitesse de rotation du moteur à combustion interne,on détermine si la différence entre la pression d’air admis pour la première position du vilebrequin et la pression d’air admis pour la deuxième position du vilebrequin est inférieure au seuil de pression d’apprentissage de la pression atmosphérique,si tel est le cas, on commande l’apprentissage de la pression atmosphérique en appliquant un filtre du premier ordre à la pression d’air admis pour la deuxième position du vilebrequin, eton commande le moteur à combustion interne en fonction de la valeur apprise de la pression atmosphérique.
