Abstract

Die Erfindung betrifft ein Verfahren zur Regelung einer Verbrennungskraftmaschine, wobei der Restsauerstoffgehalt eines Abgases der Verbrennungskraftmaschine mittels einer linearen Breitband-Lambdasonde gemessen wird und ein von dem Restsauerstoffgehalt des Abgases abhängiges Signal einem Steuergerät übermittelt wird und das Steuergerät hieraus ein die Zusammensetzung der Verbrennungskraftmaschine zugeführten Kraftstoff-Luft-Gemisch beeinflussendes Stellsignal generiert, sowie eine Vorrichtung zur Lambdaregelung einer Verbrennungskraftmaschine, die wenigstens eine in einer Abgasleitung angeordnete lineare Breitband-Lambdasonde umfasst, sowie ein Steuergerät besitzt, mittels dem ein von der Lambdasonde geliefertes Signal erfassbar ist und das Mittel zum Erstellen eines Kraftstoff-Luft-Gemisches für die Verbrennungskraftmaschine ansteuert.
Es ist vorgesehen, dass beim erfindungsgemäßen Verfahren eine Steigung der Ist-Kennlinie der linearen Breitband-Lambdasonde - während des bestimmungsgemäßen Einsatzes der linearen Breitband-Lambdasonde bei der Regelung einer Verbrennungskraftmaschine - ermittelt wird, eine Abweichung der Steigung von einer Soll-Kennlinie ermittelt wird und aus der Abweichung ein Korrekturwert ermittelt wird, mit dem das Signal der linearen Breitband-Lambdasonde korrigiert wird. Die erfindungsgemäße Vorrichtung sieht Mittel (36) vor, mittels denen eine Steigung einer Ist-Kennlinie (34) der Lambdasonde (16) ermittelbar ist und Mittel (40, 42), mittels denen eine Steigung einer Soll-Kennlinie (32) ermittelbar ist und Mittel (44, 46) zum Ermitteln eines Korrekturwertes (KLSU) des Signals (ULSU) der Lambdasonde (16).
