Abstract

L'invention porte principalement sur un procédé de pilotage d'un moteur thermique (10), notamment d'un véhicule automobile, relié à une ligne d'échappement (12) comportant un filtre à particules (16), caractérisé en ce qu'il comporte: - une étape de mesure d'un débit volumique des gaz d'échappement traversant le filtre à particules (16), - une étape de comparaison du débit volumique des gaz d'échappement mesuré avec un seuil prédéterminé, et - une étape d'adaptation d'une stratégie de mesure d'une quantité de particules accumulées dans le filtre à particules (16) en fonction du résultat de cette comparaison.
