Title: Einrichtung zur Regelung einer mehrzylindrigen Brennkraftmaschine
Inventor: FISCHER WERNER
IPC: F02D45/00
Filed: 1998-05-09
Abstract: Es wird eine Einrichtung zur Regelung einer mehrzylindrigen Brennkraftmaschine vorgeschlagen, bei der auf einer Welle der Brennkraftmaschine ein Geberrad befestigt ist, das neben regulären Winkelmarken wenigstens eine Bezugsmarke aufweist. Nach Erkennen der Bezugsmarke kann das Steuergerät der Brennkraftmaschine eine Synchronisation durchführen und ausgehend von der Synchronisation die Regelung der Brennkraftmaschine durchführen. Die erstmalige Erkennung der Bezugsmarke erfolgt durch Auswertung von Zeitspannen zwischen vorgebbaren Signalflanken. Nach erkannter Bezugsmarke wird die nächste Bezugsmarke erkannt, indem das Steuergerät Winkelmarken zählt bis zu einem Wert, der der Anzahl der Winkelmarken zwischen zwei Bezugsmarken entspricht. Eine erkannte Bezugsmarke wird auf Plausibilität überprüft, und bei erkannter Nichtplausibilität wird ein Fehler abgespeichert, jedoch die an sich nicht plausible Bezugsmarke dennoch als Synchronisationsmarke für die Regelung der Brennkraftmaschine verwendet. Erst wenn der Inhalt des Fehlerspeichers einen vorgebbaren Grenzwert übersteigt, wird ein endgültiger Defekt erkannt.
