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 Ist-Drehzahlsignalenin einem ersten Programmabschnitt einen Drehzahlwert durch Auf­ summierung der angelegten Ist-Drehzahlsignale. In einem zweiten Programmabschnitt berechnet er mit dem ermittel­ ten Drehzahlwert innerhalb einer fest vorgegebenen Zeit neue Steuersignale, die dann nach Ablauf des zweiten programmabschnittes abgegeben werden. Dadurch wird bei Mikrorechnern ohne Interrupt oder mit relativ langsamer Verarbeitungszeit ein schneller Ablauf die Signalverarbei­ tung und Signalausgabe unter bestmöglicher Ausnutzung der vorhandenen Rechengeschwindigkeit gewährleistet. 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 in one depending on the actual speed signals first program section a speed value by up summation of the actual speed signals applied. In one he calculates the second program section with the determined th speed value within a predetermined time new control signals, which then after the second program section are submitted. This will help Microcomputers without an interrupt or with a relatively slower rate Processing time a fast process the signal processing processing and signal output with the best possible use the existing computing speed guaranteed.
