Abstract

Ein Verfahren zur Optimierung von Verbrennungskraftmaschinen, insbesondere zur Emissions- und/oder Verbrauchsoptimierung, bei welchen über Korrekturfunktionen in ihren Steuergeräten in jedem Betriebspunkt gegebenenfalls zumindest eine der Nebeneinflussgrößen derart eingestellt wird, dass in einem definierten Zyklus von Betriebspunkten die Emissionsgrenzwerte eingehalten sind, soll derart verbessert werden, dass von der Messung am Motorprüfstand über die Modellbildung bis hin zur Kalibrierung der Steuergeräteparameter so viele Schritte wie möglich automatisiert ablaufen können. Dazu ist vorgesehen, dass in einem ersten Schritt ein Versuchsplan für die Haupteinflussgrößen und Nebeneinflussgrößen unter Verwendung mathematischer Modelle der Steuergerätefunktionen und der Verbrennungskraftmaschine in Bezug auf die zu optimierende Größe erstellt und am Prüfstand abgefahren wird, wobei basierend auf diesen Modellen die optimalen Werte der Nebeneinflussgrößen unter Einhaltung der Emissionsgrenzwerte bestimmt und diese Werte zur Erstbedatung der Korrekturfunktionen im Steuergerät herangezogen werden.A method for optimizing internal combustion engines, in particular for optimizing emissions and / or consumption, in which optionally at least one of the secondary influencing variables is set via correction functions in their control units at each operating point in such a way that the emission limit values are maintained in a defined cycle of operating points, is thus improved will be able to automatically automate as many steps as possible, from measuring on the engine test bench to modeling and calibrating ECU parameters. For this purpose, it is provided that in a first step, a test plan for the main influencing variables and secondary factors using mathematical models of the control unit functions and the internal combustion engine is created with respect to the size to be optimized and driven on the test bench, based on these models, the optimal values of the side influence variables Compliance with the emission limit values determined and these values are used for Erstbedatung the correction functions in the control unit.
