Abstract
The invention relates to a method for diagnosing a particulate filter by means of a soot sensor, the method being based on the direct analysis of the temporal signal supplied by the soot sensor (CAP) and the use of the available quantities (PAR) in the control unit of the heat engine. These data allow for a classification (CLA) of an indicator correlated to the cumulative quantity of soot (RES) in a multidimensional space (GRA). Based on the classification (CLA), the existence of a failure of the particulate filter is determined.
