Abstract

The soot load of a particulate filter (12) in the exhaust system of a motor vehicle is estimated by a) selecting (S2) a mission profile of the motor vehicle based on the history of one or more of its operation parameters (É, AR); b) increasing (S7) the estimated soot load at a rate (SR) associated to the currently selected mission profile; c) determining (S4) a target fuel injection rate (TFR) of an engine of the motor vehicle based on input from a driver (S3) ; d) determining a limit fuel injection rate (LFR) based on a set of operation parameters comprising at least one of the engine speed (É) and the engine airflow (AR); e) in a time interval in which the target fuel injection rate (TFR) exceeds the limit fuel injection rate (LFR), increasing the estimated soot load (S9) at a rate (TSR) associated to an instantaneous value of at least one of said operation parameters.
