Abstract

L’invention concerne un procédé de contrôle de la charge du filtre à particules de la ligne d’échappement des moteurs thermiques de véhicules automobiles comprenant, au franchissement d’au moins un seuil de charge du filtre, une phase de régénération dudit filtre, caractérisé en ce qu’on surveille le chargement du filtre en mesurant en continu le différentiel de pression des gaz d’échappement entre la sortie et l’entrée du filtre et, en cas d’une augmentation brutale et incohérente de ce différentiel, on inhibe les limitations de performance du moteur pendant une durée et/ou une distance de roulage supplémentaire et déterminée du véhicule jusqu’à obtenir la régénération du filtre. Figure 1The invention relates to a method for controlling the charge of the particulate filter in the exhaust line of thermal engines of motor vehicles comprising, when at least one filter load threshold is crossed, a phase for regenerating said filter, characterized in that the loading of the filter is monitored by continuously measuring the pressure differential of the exhaust gases between the outlet and the inlet of the filter and, in the event of a sudden and inconsistent increase in this differential, the engine performance limitations for an additional and determined duration and / or driving distance of the vehicle until regeneration of the filter is achieved.
