Abstract
Procédé de correction (100) d’une mesure (S) de débit d’air admis dans un moteur à combustion interne comprenant un premier circuit (34) de recirculation des gaz d’échappement à haute pression comportant une vanne EGR haute pression (V EGR HP) et un deuxième circuit (36) de recirculation des gaz d’échappement à basse pression comportant une vanne EGR basse pression (V EGR BP), dans lequel :- on mesure le débit d’air (S) admis dans le moteur à combustion interne ;- on détermine une valeur estimée du débit d’air (D_est) en fonction de la mesure (S) de débit d’air et de coefficients de linéarisation (ai, bi, ci, di et ei) issus d’un banc d’essai en fonction d’une valeur mesurée de débit d’air et d’une valeur de référence de débit d’air ;- on détermine un facteur de correction en fonction de la charge et du régime du fonctionnement du moteur ; et- on ajoute le facteur de correction (F) à la valeur estimée du débit d’air (D_est).
