Abstract

Procédé de commande d'un moteur à combustion interne muni d'injecteurs de carburant connectés à un rail d'alimentation en carburant alimenté en carburant par une pompe à carburant, le moteur à combustion interne étant commandé en fonction d'une consigne de point de fonctionnement, le procédé comprenant les étapes suivantes : • on détermine si une nouvelle consigne de point de fonctionnement différente de la consigne de point de fonctionnement en cours est reçue. si tel est le cas, on détermine la capacité maximale de la pompe en fonction de valeurs déterminées de la vitesse de rotation du moteur à combustion interne, de la quantité de carburant injectée et de la pression de carburant dans le rail commun d'injection, • on détermine le débit de consommation de carburant du véhicule • on soustrait le débit de consommation de carburant du véhicule de la capacité maximale de la pompe afin d'obtenir la capacité restante de la pompe à carburant, • on détermine la différence de débit de carburant entre le point de fonctionnement en cours et le point de fonctionnement de la nouvelle consigne de point de fonctionnement, si la capacité restante de la pompe à carburant est inférieure à la différence de débit de carburant, on émet une consigne de gradient de débit de carburant réduit avec la nouvelle consigne de point de fonctionnement ou on limite la quantité de carburant injectée.
