Abstract

Es wird eine Leerlaufdrehzahlregeleinrichtung für Brenn­ kraftmaschinen mit einer durch einen Mikrorechner (10) gesteuerten Vorrichtung (17, 18) vorgeschlagen, die dreh­ zahlverändernd auf die Brennkraftmaschine einwirkt. Der Mikrorechner (10) bildet zusammen mit der Brennkraftma­ schine und der Vorrichtung (17, 18) einen Regelkreis und errechnet in Abhängigkeit von der Ist-Drehzahlsignale in einem ersten Programmabschnitt einen Drehzahlwert durch Aufsummieren der angelegten Ist-Drehzahlsignale. Nachfol­ gend wird dieser Wert mit einem gespeicherten Soll-­ Drehzahlwert verglichen und je nach Abweichung aus einem die Regelkennlinien enthaltenden Festwertspeicher (12) ein Zahlenwert entnommen, der unmittelbar die Breite der nachfolgenden Steuersignale bestimmt. It becomes an idle speed control device for burning Engines with one through a microcomputer (10) controlled device (17, 18) proposed, the rotary affects the number of the internal combustion engine. The Microcomputer (10) forms together with the internal combustion engine machine and the device (17, 18) a control circuit and calculated depending on the actual speed signals in a speed value in a first program section Add up the actual speed signals created. Successor this value is saved with a stored target Speed value compared and depending on the deviation from one a read-only memory (12) containing the control characteristics Numerical value taken, which immediately the width of the subsequent control signals determined.
