57	Abstract	AB	Die Erfindung betrifft eine Steuervorrichtung für einen Verbrennungsmotor 107, die eine Sauerstoffspeichervolumen-Berechnungseinheit 115 zum Berechnen des Sauerstoffspeichervolumens eines Katalysators 120 unter Verwenden eines realen Luft/Kraftstoff-Verhälnisses, das durch einen auf der stromaufwärtigen Seite eines Katalysators 120 eingebauten Luft/Kraftstoff-Verhältnissensor 118 erfasst wird, eines Mitte-Luft/Kraftstoff-Verhältnisses, das für ein stöchiometrisches Luft/Kraftstoff-Verhältnis steht, und eines geschätzten Luftströmungsvolumens oder zum Erfassen einer Strömungsrate von Luft, die in den Katalysator 120 strömt. Eine Mitte-Luft/Kraftstoff-Verhältnis-Korrektureinheit 207 zum Korrigieren eines Mitte-Luft/Kraftstoff-Verhältnisses auf der Grundlage einer Ausgabe eines auf der stromabwärtigen Seite des Katalysators 120 vorgesehenen hinteren Luft/Kraftstoff-Verhältnissensors 126 und eines durch eine Sauerstoffspeichervolumen-Berechnungseinheit 206 berechneten Sauerstoffspeichervolumens, und die Sauerstoffspeichervolumen-Berechnungseinheit 206 berechnet ein Sauerstoffspeichervolumen unter Verwendung eines durch die Mitte-Luft/Kraftstoff-Verhältnis-Korrektureinheit 207 korrigierten Mitte-Luft/Kraftstoff-Verhältnisses.
