Abstract

L'invention concerne un procédé de correction d'une estimation de charge (M) en suies d'un filtre à particules, l'estimation de charge (M) en suies étant effectuée par un modèle par contre-pression basé sur une contre-pression en vigueur exercée par le filtre à particules dans une ligne d'échappement d'un moteur thermique l'intégrant, comprenant une étape de détection d'une variation à la baisse de la contre-pression conduisant à une sous-estimation de la charge (M) en suies alors en vigueur dans le filtre à particules, la variation à la baisse de la contre-pression étant non représentative d'une variation effective de la charge (M) en suies dans le filtre à particules et une étape de correction de l'estimation de charge (M) en suies en tenant compte de la variation de contre-pression.
