Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Aufzeichnen eines Messwerts an einem Fahrzeug nach dem Erfassen des Messwerts. Darüber hinaus beschreibt die vorliegende Erfindung eine Aufzeichnungsvorrichtung für ein Fahrzeug.The The present invention relates to a method for recording a Measured value on a vehicle after acquiring the measured value. Furthermore The present invention describes a recording apparatus for a Vehicle.
Nach dem heutigen Stand der Technik erfolgt die Analyse eines Fehlerzustands eines Fahrzeugs meist ohne ein Wissen der Bedingungen, unter denen das Fahrzeug vor dem Auftreten des Fehlers betrieben wurde. Diese, im Weiteren auch als Umgebungsbedingungen bezeichneten Randbedingungen, wie beispielsweise die Drehzahl oder die Temperatur innerhalb des Motors, sind zwar über Sensoreinrichtungen erfassbar, aber in ihrer Gesamtheit nur schwer abspeicherbar. Die Ursache dafür ist eine erhebliche Überlastung der Speicherressourcen des Fahrzeugs, welche bei einem Mitschnitt aller von den Sensoreinrichtungen erfassten Messwerte während einer Fahrt auftreten würde.To In the current state of the art, the analysis of a fault condition occurs of a vehicle usually without a knowledge of the conditions under which the vehicle was operated before the fault occurred. These, hereinafter also referred to as ambient conditions boundary conditions, such as the speed or the temperature within the Motors, though are over Detectable sensor devices, but difficult in their entirety stored. The cause is a significant overload the memory resources of the vehicle, which in a recording all measured values acquired by the sensor devices during a Drive would occur.
Das Wissen über die Umgebungsbedingungen, wie beispielsweise der Drehzahl des Motors, der Temperatur innerhalb des Motors oder anderer Werte bezüglich der Fahrweise des Fahrzeugs ist allerdings oft für die Analyse im Fehlerfall zwingend nötig. Das Unterlassen eines Mitschnitts dieser Umgebungsbedingungen führt deshalb zu dem Nachteil, dass bei Auftreten eines Fehlers die Fehlerursache ohne das Wissen über die Randbedingungen festgestellt werden muss. Dies macht die Fehlerbehebung oft recht zeitaufwendig und damit teuer.The Know about the environmental conditions, such as the speed of the engine, the temperature inside the engine or other values regarding the Driving the vehicle is however often for the analysis in case of error absolutely necessary. Failure to record these environmental conditions will therefore result to the disadvantage that when an error occurs the cause of the error without the knowledge about the boundary conditions must be determined. This makes the troubleshooting often quite time consuming and therefore expensive.
Um diesen Nachteil zu beheben, schlägt die Druckschrift G 88 16 458 ein Gerät zur laufenden Überwachung des Betriebs eines Kraftfahrzeugs vor. Dabei werden während einer Fahrt des Fahrzeugs Messwerte bezüglich der Umgebungsbedingungen erfasst und mit schon abgespeicherten Messwerten verglichen. Wird dabei eine Mindestdifferenz zwischen dem neu erfassten Messwert und dem abgespeicherten Messwert festgestellt, so wird der abgespeicherte Messwert mit dem neu erfassten Messwert überschrieben. Auf diese Weise können Abweichungswerte bezüglich der Umgebungsbedingungen während der Fahrt des Fahrzeugs aufgezeichnet werden.Around to fix this disadvantage suggests the publication G 88 16 458 a device for continuous monitoring the operation of a motor vehicle. It will be during a Driving the vehicle Measured values relating to the ambient conditions are recorded and compared with already stored measured values. Will be there a minimum difference between the newly acquired measured value and the stored measured value, then the stored Overwrites the measured value with the newly acquired measured value. In this way can Deviation values with respect to the environmental conditions during recorded during the journey of the vehicle.

ist das in Druckschrift
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zum Aufzeichnen eines Messwerts zu finden, das unter Vermeidung einer zu hohen Belastung der Speicherressourcen des Fahrzeugs eine einfachere Fehleranalyse ermöglicht.The The object of the present invention is a method to record a reading that is under avoidance too high a load on the memory resources of the vehicle simpler error analysis allows.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren zum Aufzeichnen eines Messwerts nach Anspruch 1 und eine Aufzeichnungsvorrichtung nach Anspruch 4 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens zum Aufzeichnen eines Messwerts sind in den entsprechenden Unteransprüchen definiert.According to the invention this Task by a method for recording a measured value after Claim 1 and a recording device according to claim 4. advantageous Further developments of the method according to the invention for recording of a measured value are defined in the corresponding subclaims.
Das erfindungsgemäße Verfahren und die erfindungsgemäße Aufzeichnungsvorrichtung mit einem Minimum/Maximum-Komparator erlaubt dabei eine Filterung der erfassten Messwerte bezüglich Über- und/oder Unterschreitungen von vordefinierten Schwellwerten. Damit ist eine ressourcenschonende Abspeicherung der dynamischen Zustände möglich. Dies hat den Vorteil, dass zu bestimmten Systemereignissen wichtige, auch als Randbedingungen bezeichnete Umgebungsbedingungen abgespeichert und damit bei einer Fehleranalyse mitgeliefert werden. Damit ist eine schnellere Erkennung der Ursache für das Auftreten des Fehlers und damit eine leichtere Fehlerbehebung möglich.The inventive method and the recording device according to the invention with a minimum / maximum comparator allows filtering the recorded measured values with respect to over- and / or Underruns of predefined thresholds. This is one resource-saving storage of the dynamic states possible. This has the advantage that for certain system events important, also stored as boundary conditions ambient conditions and so that they are included in a fault analysis. This is one faster detection of the cause of the error and thus easier troubleshooting possible.
