Abstract:
Particulate accumulation in a particulate filter in the exhaust line of an engine is calculated by an electronic engine control unit. When the estimated accumulated particulate mass exceeds a predetermined threshold, an automatic regeneration step of the filter is activated. An actual instantaneous burned particulate mass is calculated as a function of values indicative of the state of the filter. A temporary correction factor representing an error between a theoretical value and the actual value is calculated. The temporary correction factor is stored in a second map of correction factors, based on the engine operating conditions. During an accumulation step, the estimated instantaneous particulate mass, calculated according to the first map based on the operating conditions of the engine, is multiplied by a correction factor calculated according to the second map based on the operating conditions of the engine.

Claim (Index 10):
The method according to  claim 9 , wherein said thermal power released by the particulate combustion is calculated according to:\n values indicative of an infinitesimal increase in the internal energy of the filter, of the power transferred to the air by the filter due to convection, and of an enthalpy of the exhaust gases leaving the filter if combustion occurs, and if no combustion occurs, during the regeneration step, preferably as a function of a difference of said values, or values indicative of said infinitesimal increase of the internal energy of the filter within which no combustion occurs, of said power transferred to the air by the filter due to convection, of the thermal power released by combustion of the particulate and of a difference between said enthalpy of the exhaust gases leaving the filter and the enthalpy of the exhaust gases entering the filter.
