Der Erfindung liegt die Aufgabe zugrunde, ein Antriebssystem bzw. ein Verfahren zur Steuerung und/oder Regelung der Leerlaufdrehzahl einer Brennkraftmaschine anzugeben, wodurch eine möglichst stabile Leerlaufdrehzahl im Leerlaufbetrieb gewährleistet wird. Insbesondere soll ferner gewährleistet werden, dass Drehzahl stabilisierende Eingriffe der elektrischen Maschine nicht unnötig oft erfolgen.Of the Invention is based on the object, a drive system or a Method for controlling and / or regulating the idling speed of an internal combustion engine indicate, whereby a stable idling speed is guaranteed in idle mode. In particular, should Furthermore, be ensured that speed stabilizing Interventions of the electric machine do not take place unnecessarily often.
Der Erfindung liegt die Erkenntnis zugrunde, dass in den Fällen, in denen die Leerlaufdrehzahl der Brennkraftmaschine kennfeldgesteuert voreingestellt wird und auftretende Leerlaufdrehzahlschwankungen über schnelle Drehmoment-Eingriffe der elektrischen Maschine ausgeglichen werden, gegebenenfalls unnötige Eingriffe über die elektrische Maschine erfolgen. Diese unnötigen Eingriffe können z. B. darauf zurückgeführt werden, dass die Vorsteuerkennfelder zur Steuerung der Leerlaufdrehzahl der Brennkraftmaschine zu ungenau erstellt worden sind oder Verschleißerscheinungen der Brennkraftmaschine nicht ausreichend berücksichtigt werden.Of the Invention is based on the finding that in cases in which the idling speed of the engine map-controlled is preset and occurring idle speed fluctuations over balanced fast torque intervention of the electric machine be, if necessary, unnecessary interference the electric machine done. These unnecessary interventions can z. B. be attributed to it, that the pilot control maps for controlling the idle speed the internal combustion engine have been created too inaccurate or signs of wear the internal combustion engine is not sufficiently considered become.
Insbesondere bei Hybridantrieben umfassend einen Antriebsstrang mit einer Brennkraftmaschine und mit einer elektrischen Maschine erfolgt die Leerlaufregelung in der Regel durch Eingriffe mittels der elektrischen Maschine. Über die elektrische Maschine können auftretende Leerlaufdrehzahlschwankungen schnell ausgeregelt werden, so dass eine über die Brennkraftmaschine hierfür vorgesehene Momentreserve wegfallen oder zumindest reduziert und somit eine entsprechende Kraftstoffeinsparung realisiert werden kann. Der Betriebspunkt der Brennkraftmaschine wird dabei derart vorgesteuert, dass die systembedingt vorhandenen Verlustmomente (Reibungsverluste) kompensiert werden. Die elektrische Maschine gleich somit im Idealfall, bei einer passend applizierten Vorsteuerung der Brennkraftmaschine, lediglich auftretende dynamische Störungen aus. Wenn die Vorsteuerkennfelder nicht exakt appliziert sind, muss die elektrische Maschine zusätzlich zu den dynamisch auftretenden Störungen den stationären Momentfehler ausgleichen, und hierfür entweder dauerhaft generatorisch oder motorisch arbeiten und eingreifen. Erst wenn der Ladezustand der Batterie (insbesondere aufgrund des stationären Momentfehlers) eine vorbestimmte Ladezustandsgrenze erreicht (bzw. zu hoch oder niedrig ist) wird der Betriebspunkt der Brennkraftmaschine durch eine übergeordnete Ladezustandsregelung abgesenkt oder angehoben. Dies führt dazu, dass der mit der elektrischen Maschine gekoppelte elektrische Energiespeicher unnötig zyklisiert wird.Especially in hybrid drives comprising a drive train with an internal combustion engine and with an electric machine, the idle control usually by intervention by means of the electric machine. about the electric machine can occur idling speed fluctuations be quickly adjusted so that one over the internal combustion engine intended for this moment reserve omitted or at least reduced and thus realized a corresponding fuel economy can be. The operating point of the internal combustion engine is doing pre-controlled in such a way that the system-inherent loss moments (Friction losses) are compensated. The electric machine thus ideally, with an appropriately applied pilot control the internal combustion engine, only occurring dynamic disturbances out. If the pilot control maps are not exactly applied, must the electric machine in addition to the dynamically occurring Disturbances compensate for the stationary moment error and for this either permanent generator or motor work and intervene. Only when the state of charge of the battery (in particular due to the stationary momentary error) a predetermined Charge state limit reached (or too high or low) is the Operating point of the internal combustion engine by a parent Charge state control lowered or raised. this leads to to that of the electrical energy storage coupled to the electric machine is unnecessarily cyclized.
Erfindungsgemäß wird die Aufgabe durch die Gesamtheit der Merkmale der unabhängigen Ansprüche gelöst, während in den Unteransprüchen bevorzugte Weiterbildungen der Erfindung angegeben sind.According to the invention the task by the totality of the characteristics of the independent Claims solved while in the dependent claims preferred developments of the invention are given.
Gemäß der Erfindung wird ein Antriebssystem für ein Kraftfahrzeug vorgeschlagen, welches eine Brennkraftmaschine zur Erzeugung eines auf einen Antriebsstrang wirkenden Antriebsmoments, eine mit der Brennkraftmaschine gekoppelte elektrische Maschine zur Erzeugung eines Leerlaufdrehzahlschwankungen ausgleichenden Drehmoments sowie eine Steuereinrichtung zur Steuerung und/oder Regelung einer vorbestimmten Leerlaufdrehzahl der Brennkraftmaschine umfasst, wobei die Steuereinrichtung derart ausgebildet ist, dass ein in dieser hinterlegtes Kennfeld zur Vorsteuerung der Brennkraftmaschine oder ein in dieser hinterlegtes Kennfeld zur Vorsteuerung der elektrischen Maschine in Abhängigkeit von einer ermittelten Drehzahldifferenz aus Soll-Leerlaufdrehzahl und Ist-Leerlaufdrehzahl (oder einer hiermit korrelierenden Größe) adaptiert wird.According to the Invention is a drive system for a motor vehicle proposed, which is an internal combustion engine for generating a acting on a drive train drive torque, one with the Internal combustion engine coupled electric machine for generation an idling speed fluctuations compensating torque as well a control device for controlling and / or regulating a predetermined Idling speed of the internal combustion engine comprises, wherein the control device is formed such that a stored in this map for precontrol of the internal combustion engine or a stored in this map for feedforward control of the electrical machine in dependence from a determined speed difference from target idle speed and actual idle speed (or a variable correlated therewith) adapted becomes.
Analog hierzu sieht das erfindungsgemäße Verfahren zur Steuerung und/oder Regelung der Leerlaufdrehzahl einer Brennkraftmaschine eines Kraftfahrzeugs – wobei die Brennkraftmaschine zum Ausgleich von Schwankungen der Leerlaufdrehzahl mit einer motorisch als auch generatorisch betreibbaren elektrischen Maschine gekoppelt ist – vor, dass die elektrische Maschine die Brennkraftmaschine bei auftretenden Leerlaufdrehzahlschwankungen mit einem antreibenden oder mit einem bremsenden Drehmoment beaufschlagt, wobei die Brennkraftmaschine über eine kennfeldbasierte Vorsteuereinrichtung auf eine vorbestimmte Leerlaufdrehzahl (allg.: Regelgröße) voreingestellt wird, und parallel hierzu die elektrische Maschine über eine Reglereinrichtung in Abhängigkeit von einer erfassten Drehzahldifferenz zwischen einer vorbestimmten Soll-Leerlaufdrehzahl und einer ermittelten Ist-Leerlaufdrehzahl (Regelgrößendifferenz), zum Ausgleich der ermittelten Drehzahldifferenz (Regelgrößendifferenz), angesteuert wird und das Kennfeld der kennfeldbasierten Vorsteuereinrichtung in Abhängigkeit von der Drehzahldifferenz (Regelgrößendifferenz) adaptiert wird.Analogously, the inventive method for controlling and / or regulating the idle speed of an internal combustion engine of a motor vehicle - wherein the internal combustion engine for Compensation of fluctuations in the idle speed is coupled to a motor and generator operable electric machine - before that the electric machine applied to the internal combustion engine at idle speed fluctuations with a driving or with a braking torque, the internal combustion engine via a map-based pilot control device to a predetermined idle speed ( geng .: control variable) is preset, and parallel to the electric machine via a control device in response to a detected speed difference between a predetermined target idle speed and a determined actual idle speed (control variable), to compensate for the determined speed difference (control variable difference), is controlled and the map of the map-based pilot control device in response to the speed difference (control variable difference) is adapted.

Besonders geeignet erscheint der Einsatz des erfindungsgemäßen Antriebssystems bzw. des erfindungsgemäßen Verfahrens bei Hybridfahrzeugen, die neben einer Brennkraftmaschine noch eine elektrische Maschine zur Erzeugung von auf die Antriebsräder eines Kraftfahrzeugs wirkenden Antriebsmoment aufweisen. Bei Hybridkonzepten mit elektrifizierten Nebenaggregaten und ohne Drehmomentenwandler im Getriebe ist die Zuordnung zu einem Fehler im motorreibungsbasierten Vorsteuerkennfeld eindeutig. Im Falle von mechanischen Nebenaggregaten oder Drehmomentenwandlern muss die Adaption des Vorsteuerkennfeldes dies berücksichtigen – z. B. durch Sperrung der Adaption bei eingeschalteter Klimaanlage oder bei Auftreten von Lenkvorgängen mit Lenkunterstützung.Particularly suitable appears to be the use of the drive system or the invention Method according to the invention in hybrid vehicles, which in addition to an internal combustion engine also have an electric machine for generating drive torque acting on the drive wheels of a motor vehicle. In hybrid concepts with electrified auxiliary units and without torque converter in the gearbox, the assignment to an error in the engine friction-based pilot control map is clear. In the case of mechanical ancillaries or torque converters, the adaptation of the pilot control map must take this into account - eg. B. by blocking the adaptation when the air conditioning is switched on or in the occurrence of steering operations with steering assistance.
