Abstract

Die Erfindung betrifft ein Verfahren sowie ein zur Ausführung des Verfahrens eingerichtete Steuereinrichtung zur Ermittlung einer Rußbeladung eines Partikelfilters (22), welcher in einem Abgasweg einer Verbrennungskraftmaschine (10) angeordnet ist, die mit einem vorbestimmten Kraftstoffmassen-Sollwert (m_K Soll ) und mit einer Luftmasse entsprechend einem vorbestimmten Ladedruck-Sollwert (p_LSoll ) betrieben wird. Dabei wird zur Ermittlung der Rußbeladung in einer instationären Betriebssituation ein Rußeintrag in den Partikelfilter (22) ermittelt, indem der Rußeintrag für einen entsprechenden stationären Betriebspunkt bestimmt und dieser so korrigiert wird, dass eine Abweichung des Rußeintrags infolge der instationären Betriebssituation berücksichtigt wird.
Es ist vorgesehen, dass die Abweichung des Rußeintrags infolge der instationären Betriebssituation wenigstens in Abhängigkeit von dem vorbestimmten Ladedruck-Sollwert (p_LSoll ) und einem gemessenen Ladedruck-Istwert (p_Llst ) bestimmt wird.
