Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ermittlung des Beladungszustands eines Abgaspartikelfilters. The invention relates to a method and a device for determining the loading state of an exhaust gas particulate filter.
Neuere Kraftfahrzeuge mit Dieselmotoren sind in der Regel mit einem Abgaspartikelfiltersystem zur Abgasnachbehandlung ausgerüstet, um die gesetzlichen Vorschriften hinsichtlich Partikelausstoss einhalten zu können. Aber auch bei Ottomotoren ist eine Verschärfung der gesetzlichen Anforderungen hinsichtlich der Abgaspartikelemission zu erwarten, so dass auch Fahrzeuge mit Ottomotor zukünftig mit einem Abgaspartikelfilter ausgestattet sein dürften. Newer motor vehicles with diesel engines are usually equipped with an exhaust gas particulate filter system for exhaust aftertreatment in order to comply with the legal requirements regarding particle emissions. But even with gasoline engines, a tightening of the legal requirements with regard to the emission of exhaust particulates is to be expected, so that vehicles with petrol engines in the future should be equipped with an exhaust particulate filter.
Abgaspartikelfiltersysteme haben die Aufgabe, die bei der motorischen Verbrennung entstehenden Rußpartikel auszufiltern. Da die Rußpartikelspeicherfähigkeit eines Abgaspartikelfilters begrenzt ist, besteht die Notwendigkeit, den Abgaspartikelfilter bei entsprechend hoher Beladung zu regenerieren. Bei dieser Regeneration werden die eingelagerten Rußpartikel verbrannt, so dass in dem regenerierten Abgaspartikelfilter erneut Rußpartikel eingelagert werden können. Exhaust particle filter systems have the task of filtering out the resulting during motor combustion soot particles. Since the soot particulate storage capacity of an exhaust particulate filter is limited, there is a need to regenerate the exhaust particulate filter at a correspondingly high load. In this regeneration, the stored soot particles are burned, so that in the regenerated exhaust particulate filter soot particles can be stored again.
Die Regeneration eines Abgaspartikelfilters erfolgt üblicherweise bei einer hohen Abgastemperatur, die sich entweder im praktischen Fahrbetrieb ergibt oder bei Bedarf durch eine entsprechende Verstellung von Motorparametern erzeugt wird. Ein Aktivieren einer derartigen künstlichen Regeneration erfolgt in der Regel abhängig vom Beladungszustand des Abgaspartikelfilters, welcher üblicherweise anhand des mit steigender Partikelbeladung steigenden Abgasgegendrucks ermittelt wird. The regeneration of an exhaust particulate filter is usually carried out at a high exhaust gas temperature, which results either in practical driving or is generated if necessary by a corresponding adjustment of engine parameters. Activating such an artificial regeneration generally takes place as a function of the loading state of the exhaust gas particulate filter, which is usually determined on the basis of the increasing exhaust gas back pressure with increasing particulate loading.
Überschreitet während des Motorbetriebs der Abgasgegendruck oder der Differenzdruck über dem Partikelfilter eine vorgegebene Schwelle, dann wird unter Berücksichtigung weiterer Parameter wie beispielsweise der Betriebstemperatur und der Motordrehzahl durch eine entsprechende Verstellung von Motorparametern die Abgastemperatur über die Temperatur, bei der der Abbrand der Rußpartikel einsetzt, angehoben. Exceeds during engine operation, the exhaust back pressure or the differential pressure across the particulate filter a predetermined threshold, then taking into account other parameters such as the operating temperature and the engine speed by a corresponding adjustment of engine parameters, the exhaust gas temperature above the temperature at which the combustion of soot particles begins raised ,
Es ist bereits bekannt, einen Anstieg des Abgasgegendrucks unter Verwendung von Abgasdrucksensoren, die im Abgasstrang vor und gegebenenfalls zusätzlich hinter dem Abgaspartikelfilter verbaut sind, oder unter Verwendung von Differenzdrucksensoren, die einen Druckanstieg über dem Filtersystem messen, zu ermitteln. It is already known to ascertain an increase in the exhaust gas backpressure using exhaust gas pressure sensors which are installed in the exhaust gas line before and optionally additionally behind the exhaust gas particulate filter, or by using differential pressure sensors which measure a pressure increase across the filter system.
Ein Nachteil dieser Vorgehensweise besteht darin, dass die genannten Sensoren aufgrund der mit der Einbauposition verbundenen hohen Abgastemperatur und einer Verschmutzung durch das Abgas stark beansprucht werden. Das schlägt sich einerseits in hohen Kosten für geeignete Sensoren sowie andererseits in einer erhöhten Anfälligkeit in Bezug auf einen Ausfall der Sensoren nieder. A disadvantage of this procedure is that the said sensors are heavily stressed due to the high exhaust gas temperature associated with the installation position and pollution by the exhaust gas. This is reflected on the one hand in high costs for suitable sensors and on the other hand in an increased susceptibility to failure of the sensors down.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Ermittlung des Beladungszustands eines Abgaspartikelfilters anzugeben, das keine Abgasdrucksensoren benötigt und dennoch den Zeitpunkt einer fälligen Regeneration des Abgaspartikelfilters zuverlässig ermittelt. The object of the present invention is to provide a method for determining the loading state of an exhaust gas particulate filter that does not require exhaust gas pressure sensors and nevertheless reliably determines the time of a due regeneration of the exhaust gas particulate filter.
Diese Aufgabe wird durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Der unabhängige Patentanspruch 7 hat eine Vorrichtung zur Ermittlung des Beladungszustands eines Abgaspartikelfilters zum Gegenstand. This object is achieved by a method having the features specified in
Durch die vorliegende Erfindung wird ein Verfahren zur Ermittlung der Beladung eines Abgaspartikelfilters, welches im Abgasweg eines von einem Turbolader aufgeladenen Verbrennungsmotors angeordnet ist, bereitgestellt, bei welchem zur Ermittlung des Beladungszustands des Abgaspartikelfilters eine Analyse des Verhaltens eines Ladedruckreglers des Abgasturboladers vorgenommen wird. The present invention provides a method for determining the loading of an exhaust gas particulate filter which is arranged in the exhaust path of an internal combustion engine charged by a turbocharger, wherein an analysis of the behavior of a charge pressure regulator of the exhaust gas turbocharger is carried out to determine the loading state of the exhaust gas particulate filter.
Durch die Vornahme einer derartigen indirekten Ermittlung des Beladungszustands wird eine Messung des Abgasdruckes vor und nach dem Partikelfilter unter Verwendung von Abgasdrucksensoren entbehrlich. Auch bedarf es keines Differenzdrucksensors. Dadurch werden Probleme vermieden, die bei bekannten Verfahren aufgrund der mit der Anordnung derartiger Sensoren im heißen Abgasstrang eines Verbrennungsmotors entstehen. By performing such an indirect determination of the load state, a measurement of the exhaust gas pressure before and after the particulate filter using exhaust pressure sensors is dispensable. Also, it does not require a differential pressure sensor. As a result, problems are avoided, which arise in known methods due to the arrangement of such sensors in the hot exhaust line of an internal combustion engine.

Zu den genannten Sensorsignalen se1 gehören unter anderem das Ausgangssignal eines Fahrpedalsensors, das eine Betätigung des Fahrpedals anzeigt, das Ausgangssignal eines oder mehrerer Temperatursensoren, die jeweils eine Information über eine an einer vorgegebenen Stelle des Abgasturboladers gemessene Temperatur anzeigen, und das Ausgangssignal eines Drucksensors, der eine Information über den Druck der am Ausgang des Kompressors vorliegenden, verdichteten Luft zur Verfügung stellt. The sensor signals se1 mentioned include, inter alia, the output signal of an accelerator pedal sensor which indicates an actuation of the accelerator pedal, the output signal of one or more temperature sensors, which respectively indicate information about a temperature measured at a predetermined point of the exhaust gas turbocharger, and the output signal of a pressure sensor, providing information about the pressure of the compressed air present at the outlet of the compressor.
Die Ansteuerung der Aktuatoren des Abgasturboladers
Somit kann das Verhalten des Ladedruckreglers
Für diese Analyse des Verhaltens des Ladedruckreglers
Als Startzeitpunkt für eine derartige Langzeitbeobachtung wird in vorteilhafter Weise ein Zeitpunkt unmittelbar nach der Vornahme einer Regeneration gewählt. Zu diesem Zeitpunkt erfolgt ein Rücksetzen der genannten Adaptionswerte für die Vorsteuerung des Abgasturboladers. Von diesem Zeitpunkt ausgehend ist eine neue Langzeitbeobachtung der Adaptionswerte für die Vorsteuerung des Abgasturboladers vorzunehmen. As the starting time for such a long-term observation, a time instant immediately after a regeneration is advantageously selected. At this time, a reset of the said adaptation values for the pilot control of the exhaust gas turbocharger takes place. Starting from this point in time, a new long-term observation of the adaptation values for the pilot control of the exhaust-gas turbocharger is to be carried out.
Alternativ oder zusätzlich dazu kann auch überprüft werden, ob langfristig charakteristische Veränderungen der vom Ladedruckregler ausgegebenen Steuersignale auftreten. Des Weiteren kann alternativ oder zusätzlich dazu überprüft werden, ob langfristig charakteristische Abweichungen zwischen dem Ladedrucksollwert und dem Ladedruckistwert auftreten. Alternatively or additionally, it can also be checked whether long-term characteristic changes of the control signals output by the boost pressure regulator occur. Furthermore, as an alternative or in addition, it can be checked whether long-term characteristic deviations occur between the boost pressure setpoint and the boost pressure actual value.
Alle vorgenannten Überprüfungen erfolgen in Abhängigkeit von auftretenden Änderungen des Abgasgegendrucks. All the above checks are made in response to changes occurring in the exhaust back pressure.
Nach alledem stellt die vorliegende Erfindung ein Verfahren und eine Vorrichtung bereit, bei welchen ein Rückschluss von einem geänderten Vorsteuerbedarf des Abgasturboladers auf eine Veränderung des Abfalls des Drucks über die Turbine in Folge eines durch eine zunehmende Beladung des Abgaspartikelfilters verursachten Anstieg des Abgasgegendrucks im Abgaspartikelfilter gezogen wird. Accordingly, the present invention provides a method and apparatus in which a conclusion is drawn from a change in the pilot exhaust demand of the exhaust gas turbocharger to a change in the pressure drop across the turbine as a result of an increase in exhaust back pressure in the exhaust particulate filter caused by an increase in exhaust particulate filter loading ,
