Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung des Drosselklappenwinkels bei dem mittels eines Drosselklappenmodells aus einem Luftmassenstrom und einem Differenzdruck über der Drosselklappe die Drosselklappenstellung bestimmt wird.
Zur Verringerung des Applikationsaufwandes und zum Ermöglichen der Drosselklappenwinkelbestimmung auch bei kleinen Differenzdrücken über der Drosselklappe wird vorgeschlagen, das Drosselklappenmodell aus einem unterkritischen Luftmassenstrom durch die Drosselklappe zu bestimmen, wobei das Drosselklappenmodell zumindest zwei Kennfelder enthält, von denen das erste zumindest zwei Kennfeldlinien enthält, welche den Zusammenhang des Drosselklappenwinkels zur Luftmasse bei unterschiedlichen Differenzdrücken beschreiben, und das zweite Kennfeld den nichtlinearen Übergang zwischen den im ersten Kennfeld vorliegenden Kennfeldlinien angibt.
