Beschreibung
Zusammenfassung:	The method involves calculating a quantity of soot (96) present upstream of a particle filter (82) by integration of instantaneous measurement of the quantity of soot present upstream of the particle filter over a given time interval. The quantity of soot stored by the particle filter is evaluated by the difference in thermodynamic conditions at upstream and downstream terminals of the particle filter for the given time interval. The difference between the quantity of soot present upstream of the particle and the quantity of soot stored by the particle filter is determined. Independent claims are also included for the following: (1) a method for diagnosing a particle filter arranged in a combustion gas exhaust line (2) a system for diagnosing malfunction of a particle filter arranged in a combustion gas exhaust line comprising a sensor (3) a combustion gas exhaust line including a particle filter (4) a motor vehicle including a heat engine. L'invention concerne un procédé de détermination de la quantité de suies émises à l'aval d'un filtre à particules (82), le procédé comprenant le calcul de la quantité de suies présentes en amont du filtre à particules (82) par intégration d'une mesure instantanée de la quantité de suies en amont du filtre à particules (82) ; l'évaluation de la quantité de suies stockées par le filtre à particules (82) par la différence de conditions thermodynamiques aux bornes aval et amont du filtre à particules (82) ; la différence entre la quantité de suies en amont du filtre à particules (82) et la quantité de suies stockées (82). L'invention concerne en outre un procédé et un système de diagnostic du dysfonctionnement du filtre à particules (82). L'invention permet de déterminer de la quantité de suies émises à l'aval du filtre à particules sans capteur de suies à l'aval du filtre à particules.
