Abstract
■ ein mehrere Kennfelder umfassender Satz von Kennfeldern bereitgestellt wird, welcher den funktionalen Zusammenhang zwischen der Rußkonzentration und der Stickoxidkonzentration für verschiedene Betriebszustände der Brennkraftmaschine wiedergibt,
■ die aktuelle Stickoxidkonzentration im Abgas mittels Sensor (3) ermittelt wird,
■ die auf diese Weise ermittelte aktuelle Stickoxidkonzentration zusammen mit mindestens zwei weiteren Parametern, die den Betriebszustand der Brennkraftmaschine beschreiben, als Eingangssignale für den Satz von Kennfeldern verwendet wird, um die aktuelle Rußkonzentration als Ausgangssignal auszulesen.
