Beschreibung
Zusammenfassung:	A particulate filter device monitoring system for an internal combustion engine includes a particulate accumulation register configured to store an amount of particulate in a particulate filter. The particulate accumulation register includes a particulate accumulation trigger zone having a power limiting mode trigger. A power limiting mode trigger module is configured to limit output power of the internal combustion engine when the amount of particulate accumulation reaches the power limiting mode trigger. A particulate accumulation model module includes a particulate accumulation model configured to calculate changes in particulate accumulation in the particulate accumulation register at a first sampling rate when particulate accumulation is outside the particulate accumulation trigger zone, and at a second sampling rate when particulate accumulation is within the particulate accumulation trigger zone.
