Abstract

Damit es nicht zur Beeinträchtigung des Fahrverhaltens aufgrund hoher Ausschläge der Lambdaregelung bei extremen Dynamikvorgängen kommt, wird die Lambdaregelung (1) der Brennkraftmaschine deaktiviert, wenn entweder eine hohe Gemischanreicherung (B_bag) auftritt, welche für eine vorgegebene Zeitdauer (TVUKGBM) eine Schwelle überschreitet, oder wenn eine hohe Gemischabmagerung (B_bag) auftritt, welche für eine vorgegebene Zeitdauer (TVUKGVM) eine Schwelle unterschreitet.

Figure 00000001
So that there is no impairment of the driving behavior due to high deflections of the lambda control in extreme dynamic processes, the lambda control (1) of the internal combustion engine is deactivated when either a high mixture enrichment (B_bag) occurs which exceeds a threshold for a predetermined period of time (TVUKGBM), or when a high mixture leanness (B_bag) occurs, which falls below a threshold for a predetermined period of time (TVUKGVM).
