Die Erfindung geht von einer Erhöhung des Leerlaufdrehzahl-Sollwerts einer Brennkraftmaschine während der Regeneration einer im Abgasbereich einer Brennkraftmaschine angeordneten Abgasreinigungsvorrichtung gegenüber einem Leerlaufdrehzahl-Grundsollwert aus. Die Erhöhung des Leerlaufdrehzahl-Sollwerts der Brennkraftmaschine ist zur Erhöhung der Abgastemperatur und/oder zur Erhöhung des Abgasstroms vorgesehen.The The invention is based on an increase in the idle speed setpoint an internal combustion engine during the regeneration of a In the exhaust gas region of an internal combustion engine arranged exhaust gas purification device against an idle speed basic setpoint. The Increase of the idling speed setpoint of the internal combustion engine is to increase the exhaust gas temperature and / or increase provided the exhaust stream.
Zur Information eines Betreibers der Brennkraftmaschine wird die Drehzahl der Brennkraftmaschine angezeigt. Ein Anzeige-Drehzahlsignal, welches der Anzeige zugrunde liegt, wird während der Erhöhung des Leerlaufdrehzahl-Sollwerts derart geändert, dass die Erhöhung des Leerlaufdrehzahl-Sollwerts – und somit die erhöhte Leerlaufdrehzahl der Brennkraftmaschine – während der Regeneration der Abgasreinigungsvorrichtung wenigstens näherungsweise keine Auswirkungen auf die angezeigte Drehzahl hat.to Information of an operator of the internal combustion engine is the speed the internal combustion engine displayed. A display speed signal which the ad is based, during the increase of the idling speed command value is changed so that the Increase idle speed setpoint - and Thus, the increased idle speed of the engine - during the regeneration of the exhaust gas purification device at least approximately has no effect on the displayed speed.
Mit der erfindungsgemäß vorgesehenen Maßnahme wird erreicht, dass der Betreiber der Brennkraftmaschine die Leerlaufdrehzahlerhöhung und somit den Regenerationsvorgang der Abgasreinigungsvorrichtung nicht wahrnimmt.With the measure provided for by the invention is achieved that the operator of the internal combustion engine, the idle speed increase and thus not the regeneration process of the exhaust gas purification device perceives.
Es kann davon ausgegangen werden, dass beim Betreiben der Brennkraftmaschine mit dem Leerlaufdrehzahl-Sollwert ein niedriger Geräuschpegel vorliegt, bei welchem eine Veränderung durch die Erhöhung des Leerlaufdrehzahl-Sollwerts die Aufmerksamkeit des Betreibers der Brennkraftmaschine erregt wird, die nicht noch zusätzlich durch eine Veränderung der Anzeige der Brennkraftmaschinen-Drehzahl gesteigert werden soll. Die an sich auftretende Geräuschänderung kann durch wenigstens einen weiteren Eingriff in den Betrieb der Brennkraftmaschine wie beispielsweise eine Spätverschiebung eines Zündzeitpunkts oder eine Verschiebung des Kraftstoffeinspritz-Zeitpunkts abgeschwächt werden, so dass der Beginn der Regeneration unauffällig bleibt.It can be assumed that when operating the internal combustion engine with the idle speed setpoint a low noise level is present, in which a change by the increase the idle speed setpoint the operator's attention the internal combustion engine is energized, which is not additional by a change in the display of the engine speed should be increased. The noise change that occurs in itself can by at least one further intervention in the operation of Internal combustion engine such as a late shift of a Ignition timing or a shift of the fuel injection timing be weakened, so that the beginning of regeneration unobtrusive remains.
Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Vorgehensweise ergeben sich aus abhängigen Ansprüchen.advantageous Embodiments and developments of the invention Approach arise from dependent claims.
Eine Ausgestaltung der erfindungsgemäßen Vorgehensweise sieht vor, dass das Anzeige-Drehzahlsignal während der Erhöhung des Leerlaufdrehzahl-Sollwerts der Brennkraftmaschine derart geändert wird, dass das Anzeige-Drehzahlsignal dem Leerlaufdrehzahl-Grundsollwert entspricht. Der Vorteil dieser Ausgestaltung liegt in der einfachen Realisierung.A Embodiment of the procedure according to the invention provides that the display speed signal during the Increase of the idling speed setpoint of the internal combustion engine is changed so that the display speed signal to the idle speed basic setpoint equivalent. The advantage of this embodiment lies in the simple Realization.
Eine andere Ausgestaltung sieht vor, dass das Anzeige-Drehzahlsignal während der Erhöhung des Leerlaufdrehzahl-Sollwerts derart geändert wird, dass das Anzeige-Drehzahlsignal den zuletzt vor dem Auftreten der Regeneration-Anforderung vorgegebenen Leerlaufdrehzahl-Sollwert entspricht. Mit dieser Maßnahme wird eine geringstmögliche Änderung bei der Anzeige der Leerlaufdrehzahl der Brennkraftmaschine erzielt. Zur Realisierung dieser Ausgestaltung ist ein Drehzahlspeicher vorgesehen, der den Leerlaufdrehzahl-Sollwert zwischenspeichert.Another embodiment provides that the display speed signal during the increase of the idle speed setpoint value is changed such that the display speed signal corresponds to the last specified before the occurrence of the regeneration request idle speed setpoint. With this measure, a least possible change in the display of the idle speed of the internal combustion engine is achieved. To realize this embodiment, a speed memory is provided, the the idle speed setpoint buffered.
Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens betrifft zunächst ein Steuergerät, das zur Durchführung des Verfahrens speziell hergerichtet ist.The inventive device for implementation of the method initially relates to a control unit, specially prepared for carrying out the method is.
Das Steuergerät enthält vorzugsweise wenigstens einen elektrischen Speicher, in welchem die Verfahrensschritte als Steuergerätprogramm abgelegt sind.The Control unit preferably contains at least one electrical memory, in which the process steps as a control unit program are stored.
Das erfindungsgemäße Steuergerätprogramm sieht vor, dass alle Schritte des erfindungsgemäßen Verfahrens ausgeführt werden, wenn das Programm in einem Steuergerät abläuft.The Control unit program according to the invention provides that all steps of the invention Procedure be executed when the program in a Control unit expires.
Das erfindungsgemäße Steuergerät-Programmprodukt mit einem auf einem maschinenlesbaren Träger gespeicherten Programmcode führt das erfindungsgemäße Verfahren aus, wenn das Programm in einem Steuergerät abläuft.The Control unit program product according to the invention with a stored on a machine-readable carrier Program code carries the inventive Procedure when the program runs in a controller.
