Abstract

Die Erfindung betrifft ein Verfahren zur Nockenwellenverstellung in einer Brennkraftmaschine, wobei die Nockenwelle bzgl. einer Kurbelwelle mittels eines von einem Regler und einem Proportionalventil betätigten Verstellers um einen vorbestimmten Winkel verschwenkt wird, wobei der Regler einen Winkelsollwert mit einem Winkelistwert vergleicht, in Abhängigkeit von diesem Vergleich eine Stellgröße in Form eines Tastverhältnisses für das Proportionalventil bestimmt und bei Übereinstimmung von Winkelsoll- und Winkelistwert diese Stellgröße auf ein Haltetastverhältnis derart einstellt, daß der Winkelsollwert gehalten wird. Hierbei wird während einer Verstellung der Nockenwelle vor einem jeweiligen Soll-/Istwertvergleich dem Winkelistwert ein Prädiktionswinkel derart hinzuaddiert, daß die Summe aus Winkelistwert und Prädiktionswinkel einem Winkel der Nockenwelle entspricht, den diese nach Umstellen der Stellgröße auf den Haltewert bis zum vollständigen Schließen des Proportionalventils während einer Ventilschließzeit erreicht.
