Abstract

Zur Korrektur der Kennlinie einer Breitband-Lambda-Sonde (5), die in einer Abgasreinigungsanlage einer Brennkraftmaschine (10) stromauf eines Katalysators (6) angeordnet ist, wird in einer Schubabschaltungsphase ein Signalpegel des Signals der Lambda-Sonde (5) bestimmt und dem der Sauerstoffkonzentration der Umgebungsluft entsprechende Lambda-Wert zugeordnet. Dabei wird die Steigung des Signals der Lambda-Sonde (5) während der Schubabschaltung berücksichtigt.
