Description
Die Erfindung betrifft ein Motorsteuergerät nach dem Oberbegriff des Anspruchs 1.The invention relates to an engine control unit according to the preamble of claim 1.
Als Aktuatoren kommen in solchen Common-Rail-Kraftstoffversorgungsanlagen zunehmend Magnetaktuatoren zum Einsatz. So zeigt
Bislang besteht keine Möglichkeit, Magnetaktuatoren im an der Brennkraftmaschine bzw. im in der Kraftstoffversorgungsanlage verbauten Zustand zu überprüfen. Vielmehr muss zur Überprüfung solcher Magnetaktuatoren auf die Kraftstoffversorgungsanlage derart zugegriffen werden, dass eine spezielle Messvorrichtung an die Magnetaktuatoren gekoppelt wird, um dieselben einer Funktionsüberprüfung zu unterziehen. Dies ist allerdings nur dann möglich, wenn an einer Brennkraftmaschine ohnehin Wartungsarbeiten ausgeführt werden. Daher besteht die Gefahr, dass ein Magnetaktuator im Betrieb außerhalb der regulären Wartungsintervalle der Brennkraftmaschine ausfällt und es somit zu einem ungewünschten Motorstopp der Brennkraftmaschine und damit zu kostenintensiven Ausfallzeiten derselben kommt.So far, there is no way to check Magnetaktuatoren in on the internal combustion engine or installed in the fuel supply system state. Instead, in order to check such magnetic actuators, the fuel supply system must be accessed in such a way that a special measuring device is coupled to the magnetic actuators in order to subject them to a functional check. However, this is only possible if maintenance work is carried out on an internal combustion engine anyway. Therefore, there is a risk that a magnetic actuator fails during operation outside the regular maintenance intervals of the internal combustion engine and thus it comes to an unwanted engine stop of the internal combustion engine and thus costly downtime of the same.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein neuartiges Motorsteuergerät zu schaffen. Diese Aufgabe wird durch ein Motorsteuergerät nach Anspruch 1 gelöst. Erfindungsgemäß umfasst das Motorsteuergerät Mittel, um im Stillstand der Brennkraftmaschine bei druckloser Kraftstoffversorgungsanlage automatisch einen Istwert mindestens einer magnetischen Kenngröße mindestens eines Magnetaktuators zu ermitteln und derart auszuwerten, dass das Motorsteuergerät dann, wenn der jeweilige Istwert von einem entsprechenden Sollwert um weniger als einen vorbestimmten Betrag abweicht, automatisch auf einen ordnungsgemäß arbeitenden Magnetaktuator schließt, wohingegen das Motorsteuergerät dann, wenn der jeweilige Istwert vom entsprechenden Sollwert um mehr als einen vorbestimmten Betrag abweicht, automatisch auf einen nicht ordnungsgemäß arbeitenden Magnetaktuator schließt.On this basis, the present invention has the object to provide a novel engine control unit. This object is achieved by an engine control unit according to claim 1. According to the invention, the engine control unit comprises means for automatically detecting an actual value of at least one magnetic characteristic of at least one magnetic actuator when the internal combustion engine is at zero pressure fuel supply and evaluating such that the engine control unit deviates from a corresponding desired value by less than a predetermined amount , automatically closes to a properly operating magnetic actuator, whereas when the respective actual value deviates from the corresponding desired value by more than a predetermined amount, the engine control unit automatically closes to an improperly operating magnetic actuator.
Mit der hier vorliegenden Erfindung wird erstmals vorgeschlagen, dass in das Motorsteuergerät einer Brennkraftmaschine Mittel integriert sind, um im Stillstand der Brennkraftmaschine bei druckloser Kraftstoffversorgungsanlage automatisch eine Funktionsüberprüfung von Magnetaktuatoren der Kraftstoffversorgungsanlage auszuführen. Hierzu ermittelt das Motorsteuergerät automatisch einen Istwert mindestens einer magnetischen Kenngröße mindestens eines Magnetaktuators und wertet denselben automatisch derart aus, dass dann, wenn der jeweilige Istwert von einem entsprechenden Sollwert um weniger als einen vorbestimmten Betrag abweicht, automatisch auf ein ordnungsgemäß arbeitenden Magnetaktuator geschlossen wird. Dann hingegen, wenn der jeweilige Istwert vom entsprechenden Sollwert um mehr als den vorbestimmten Betrag abweicht, schließt das Motorsteuergerät automatisch auf einen nicht ordnungsgemäß arbeitenden Magnetaktuator.With the present invention, it is proposed for the first time that means are integrated in the engine control unit of an internal combustion engine to automatically carry out a functional check of magnetic actuators of the fuel supply system when the internal combustion engine is at zero pressure in the fuel supply system. For this purpose, the engine control unit automatically determines an actual value of at least one magnetic characteristic of at least one Magnetaktuators and automatically evaluates the same so that when the respective actual value deviates from a corresponding setpoint by less than a predetermined amount, automatically closed to a properly operating Magnetaktuator. Then, however, if the respective actual value deviates from the corresponding setpoint value by more than the predetermined amount, the engine control unit automatically closes on an improperly operating magnetic actuator.
Mit der Erfindung ist es möglich, außerhalb der regulären Wartungsarbeiten an einer Brennkraftmaschine und damit außerhalb der regulären Wartungsintervalle im Stillstand der Brennkraftmaschine bei druckloser Kraftstoffversorgungsanlage automatisch ohne manuellen Zugriff und ohne diesbezügliche Arbeiten an der Kraftstoffversorgungsanlage bzw. an der Brennkraftmaschine die Magnetaktuatoren der Kraftstoffversorgungsanlage automatisch einer Funktionsüberprüfung zu unterziehen. Hierdurch ist es möglich, rechtzeitig auf einen fehlerhaft arbeitenden Magnetaktuator zu schließen und rechtzeitig eine individuelle Wartung bzw. einen Austausch desselben zu veranlassen, um so einen ungeplanten Motorstopp infolge eines Ausfalls eines Magnetaktuators zu vermeiden.With the invention, it is possible outside the regular maintenance on an internal combustion engine and thus outside of the regular maintenance intervals at standstill of the internal combustion engine with pressureless fuel supply system automatically without manual access and without related work on the fuel supply system or on the internal combustion engine to automatically subject the magnetic actuators of the fuel supply system to a functional check. This makes it possible to close timely to a malfunctioning magnetic actuator and timely initiate an individual maintenance or replacement thereof so as to avoid an unplanned engine stop due to a failure of a Magnetaktuators.
Vorzugsweise weist das Motorsteuergerät Schnittstellen auf, um die Magnetaktuatoren anzusteuern und mit denselben Daten auszutauschen, ebenso hardwareseitige Baugruppen zur automatischen Ermittlung des Istwerts der oder jeder magnetischen Kenngröße der Magnetaktuatoren und softwareseitige Baugruppen zur automatischen Auswertung des Istwerts der oder jeder magnetischen Kenngröße der Magnetaktuatoren.Preferably, the engine control unit has interfaces to control the magnetic actuators and to exchange the same data, as well as hardware assemblies for automatically determining the actual value of the or each magnetic characteristic of the magnetic actuators and software assemblies for automatically evaluating the actual value of the or each magnetic characteristic of the magnetic actuators.
Eine derartige Ausgestaltung des Motorsteuergeräts ist bevorzugt und erlaubt eine vollautomatische Funktionsüberprüfung der Magnetaktuatoren einer Kraftstoffversorgungsanlage.Such an embodiment of the engine control unit is preferred and allows a fully automatic functional check of the magnetic actuators of a fuel supply system.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:Preferred embodiments of the invention will become apparent from the dependent claims and the description below.
