Abstract
Die Erfindung betrifft ein Verfahren zur λ-Regelung bei einem Verbrennungsmotor mit einer Motorsteuerung zur Gemischbildung und einer in einer Abgasanlage des Verbrennungsmotors angeordneten λ-Sonde zur Erzeugung eines einen Sauerstoffgehalt eines in der Abgasanlage geführten Abgases mittels einer hinterlegten Kennlinie charakterisierenden Sondensignals. Das Verfahren weist folgende Schritte auf: - Vorsteuern von Gemischänderungen des Verbrennungsmotors mittels der Motorsteuerung; - Adaptieren der hinterlegten Kennlinie der λ-Sonde unter Verwendung der vorgesteuerten Gemischänderungen.
