Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung eines Verbrennungsmotors der überwiegend in einer Betriebsart mit einem mageren Luft-Kraftstoff-Gemisch (λ>>1), zur Regeneration seines Speicherkatalysators jedoch zyklisch mit einem fetten Luft-Kraftstoff-Gemisch (λ<1) betrieben wird.The invention relates to a method for controlling an internal combustion engine predominantly in an operating mode with a lean air-fuel mixture (λ >> 1), however, for the regeneration of its storage catalytic converter rich air-fuel mixture (λ <1) is operated.

Zur Vermeidung von Komforteinbußen infolge der Wirkungsgradänderung beim Umschalten von der Betriebsart mit magerem Luft-Kraftstoff-Gemisch in diejenige mit fettem Luft-Kraftstoff-Gemisch wird vorgeschlagen, einen Fahrerwunsch zu ermitteln, einen Drehzahl-Sollwert aus dem Fahrerwunsch zu generieren, einen Drehzahl-lstwert zu bestimmen, eine Differenzdrehzahl aus dem Drehzahl-Sollwert und dem Drehzahl-Istwert zu ermitteln, eine Korrekturgröße in Abhängigkeit von der Differenzdrehzahl zu ermitteln und einen Wert für die Einspritzmenge und/oder die Luftmasse in Abhängigkeit von der Korrekturgröße zu ermitteln.

Figure 00000001
To avoid loss of comfort due to the change in efficiency when switching from the operating mode with a lean air-fuel mixture to that with a rich air-fuel mixture, it is proposed to determine a driver's request, to generate a speed setpoint from the driver's request, an actual speed value to determine, to determine a differential speed from the speed setpoint and the actual speed value, to determine a correction variable as a function of the differential speed and to determine a value for the injection quantity and / or the air mass as a function of the correction variable.
