Abstract

Nach einem Sprung von einer Vorgabe eines fetten Luft/Kraftstoff-Verhältnisses in einem Brennraum eines jeweiligen Zylinders einer Brennkraftmaschine zu einer Vorgabe eines mageren Luft/Kraftstoff-Verhältnisses wird auf eine sich daraufhin einstellende Plateauphase eines Messsignals einer in einem Abgaskatalysator angeordneten Abgassonde detektiert und die Zeitdauer der Plateauphase als Einlagerungszeitdauer (T_PL_L) ermittelt. Nach einem Sprung von einer Vorgabe eines mageren Luft/Kraftstoff-Verhältnisses in dem Brennraum des jeweiligen Zylinders zu einer Vorgabe eines fetten Luft/Kraftstoff- Verhältnisses wird auf eine sich daraufhin einstellende Plateauphase (PL) des Messsignals (MSl) detektiert und die Zeitdauer der Plateauphase als Auslagerungszeitdauer (T_PL_R) ermittelt. Abhängig von der Einlagerungszeitdauer (T_PL_L) und der Auslagerungszeitdauer (T_PL_R) wird eine Zuordnungsvorschrift zum Zuordnen des Messsignals zu einem erfassten Luft/Kraftstoff-Verhältnis (LAMB-AV) angepasst. Zum Kalibrieren der Abgassonde wird abhängig von einem Plateauwert (PL_V) des Messsignals (MSl) während der Plateauphase (PL) die Zuordnungsvorschrift angepasst.
