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.The invention relates to a method for determining the throttle valve angle in which by means of a throttle valve model from an air mass flow and a differential pressure across the throttle valve position is determined.

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.

Figure 00000001
In order to reduce the application effort and to enable the throttle valve angle to be determined even with small differential pressures above the throttle valve, it is proposed to determine the throttle valve model from a subcritical air mass flow through the throttle valve, the throttle valve model containing at least two characteristic maps, the first of which contains at least two characteristic map lines which represent the Describe the relationship of the throttle valve angle to the air mass at different differential pressures, and the second map indicates the nonlinear transition between the map lines present in the first map.
