Abstract

L’invention porte principalement sur un procédé d'adaptation d'une durée de régénération d'un filtre à particules pour moteur thermique, comportant: - une étape d'estimation d'une masse de suies (M_est) dans le filtre à particules à l'issue d'une régénération, - une étape de détermination d'une masse de suies réelle (M_r) contenue à l'intérieur du filtre à particules à l'issue de la régénération, - et en cas de détection d'un écart entre la masse de suies réelle (M_r) et la masse de suies estimée (M_est) via le modèle de combustion, ledit procédé comporte en outre: - une étape de détermination d'un gain correctif à appliquer sur la constante cinétique nominale de la réaction de combustion des suies pour obtenir une constante cinétique réelle, et - une étape d'application de la constante cinétique réelle dans le modèle de combustion des suies.
