Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Hybridantriebsvorrichtung eines Fahrzeugs, insbesondere eines Kraftfahrzeugs, die mindestens eine Brennkraftmaschine und mindestens eine damit wirkverbindbare elektrische Maschine aufweist, wobei der Hybridantriebsvorrichtung im Leerlauf eine Leerlaufdrehzahl vorgegeben wird.The The invention relates to a method for operating a hybrid drive device a vehicle, in particular a motor vehicle, the at least an internal combustion engine and at least one operatively connected thereto having electrical machine, wherein the hybrid drive device idle an idle speed is specified.
Stand der TechnikState of the art
Verfahren der eingangs genannten Art sind bekannt. So ist es üblich, die Brennkraftmaschine mit einer Leerlaufregelung zu versehen, die dafür sorgt, dass bei einem fehlenden oder zu geringen Antriebsdrehmomentenwunsch, zum Beispiel wenn ein Fahrpedal des Fahrzeugs nicht betätigt wird, die Brennkraftmaschine mit einer bestimmten Mindestdrehzahl, der so genannten Leerlaufdrehzahl, läuft. Hierdurch wird ein ungewolltes Abstellen/Absterben der Brennkraftmaschine verhindert. Es ist bekannt, diese Regelung auch bei Hybridantriebsvorrichtungen einzusetzen, sodass die Brennkraftmaschine stets mit der Mindestdrehzahl läuft. Da von heutigen (Hybrid-)Antriebsvorrichtungen von Fahrzeugen eine hohe Dynamik gefordert wird, wird die Brennkraftmaschine im Leerlauf üblicherweise so betrieben, dass eine Momentenreserve aufgebaut wird. Dies geschieht durch eine Erhöhung der Frischluftfüllung, beispielsweise durch ein weiteres Öffnen einer Drosselklappe der Brennkraftmaschine, und gleichzeitiger Wirkungsgradverschlechterung, beispielsweise durch Verändern des Zündwinkels der Brennkraftmaschine nach Spät. Die sonst aufgrund einer Saugrohrdynamik nur träge reagierende Brennkraftmaschine kann durch Aufbau der Momentenreserve schneller auf eine Drehmomentanforderung reagieren, wobei hierzu lediglich der Zündwinkel verändert werden muss. Da die Veränderung eines Zündwinkels sehr schnell, beispielsweise von einer Kurbelwellenumdrehung zur nächsten, verändert werden kann, ist dadurch eine hohe Dynamik der Brennkraftmaschine gegeben, die jedoch einen verschlechterten Wirkungsgrad der Brennkraftmaschine bedeutet.method The type mentioned above are known. So it is common for the To provide internal combustion engine with an idle control, which ensures that in the case of a missing or insufficient drive torque requirement, for example, if an accelerator pedal of the vehicle is not actuated, the internal combustion engine with a certain minimum speed, the so-called idle speed, running. As a result, an unwanted shutdown / dying of the internal combustion engine prevented. It is known that this regulation also in hybrid drive devices use, so that the internal combustion engine always with the minimum speed running. Since of today's (hybrid) drive devices of vehicles a high Dynamics is required, the internal combustion engine is idling normally operated so that a torque reserve is established. this happens by an increase the fresh air filling, for example by another opening a throttle of the internal combustion engine, and at the same time efficiency deterioration, for example, by changing the ignition angle the internal combustion engine after late. The otherwise due to a Saugrohrdynamik only slowly reacting engine can build up the torque reserve faster to a torque request react, in which case only the ignition angle to be changed got to. Because the change a firing angle very fast, for example from a crankshaft revolution to next changed can be, this is a high dynamics of the internal combustion engine given, however, a deteriorated efficiency of the internal combustion engine means.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren sieht vor, dass die Leerlaufdrehzahl jeweils anteilig von der Brennkraftmaschine und der elektrischen Maschine bewirkt wird. Es ist also vorgesehen, dass die Leerlaufdrehzahl der Hybridantriebsvorrichtung jeweils anteilig von der Brennkraftmaschine und der elektrischen Maschine bewirkt beziehungsweise gestellt wird, wobei hierzu zweckmäßigerweise eine zwischen Brennkraftmaschine und elektrischer Maschine angeordnete Kupplung geschlossen wird/ist. Unter der Leerlaufdrehzahl der Hybridantriebsvorrichtung ist hierbei also eine Drehzahl der gesamten Hybridantriebsvorrichtung zu verstehen, die von den unterschiedlichen Antriebsaggregaten, der elektrischen Maschine und der Brennkraftmaschine, erbracht beziehungsweise beeinflusst werden kann, wobei das zum Erreichen der Leerlaufdrehzahl notwendige Drehmoment erfindungsgemäß anteilig von der Brennkraftmaschine und der elektrischen Maschine gestellt beziehungsweise geleistet wird, wodurch das anteilige Bewirken der Leerlaufdrehzahl erfolgt. Insbesondere handelt es sich bei der Leerlaufdrehzahl der Hybridantriebsvorrichtung um eine Getriebeeingangsdrehzahl, mit der ein Getriebe des Fahrzeugs angetrieben wird, wenn eine Anfahrkupplung zwischen der Hybridantriebsvorrichtung und dem Getriebe geschlossen wird beziehungsweise ist. Durch die anteilige Beaufschlagung der Brennkraftmaschine und der elektrischen Maschine mit Solldrehmomenten zum Erreichen der vorgegebenen Leerlaufdrehzahl wird sowohl die Dynamik als auch der Wirkungsgrad des Gesamtsystems (der Hybridantriebsvorrichtung) verbessert, da nunmehr schnelle Drehmomentänderungen von der elektrischen Maschine bewirkt werden und auf den Aufbau einer Momentenreserve verzichtet werden kann. Wobei derartige Drehmomentänderungen unterschiedliche Ursachen haben können: So wird das Drehmoment der Hybridantriebsvorrichtung beispielsweise dadurch beeinflusst, dass ein Kühlaggregat, das beispielsweise über einen Riementrieb von der Brennkraftmaschine angetrieben wird, hinzugeschaltet wird und dadurch das Drehmoment der Brennkraftmaschine und somit der Hybridantriebsvorrichtung beeinflusst. Wird von der Hybridantriebsvorrichtung eine schnelle Drehmomenterhöhung gefordert, beispielsweise weil der Fahrer das Fahrpedal entsprechend betätigt, so kann die Trägheit der Brennkraftmaschine durch die elektrische Maschine ausgeglichen werden. Im Rollbetrieb des Fahrzeugs wird das Fahrzeug mit der Leerlaufdrehzahl der Hybridantriebsvorrichtung angetrieben. Möchte der Fahrer das Fahrzeug aus dem Stand in die Rollbewegung überführen, so schließt er beispielsweise durch Lösen des Kupplungspedals die Anfahrtskupplung zwischen dem Getriebe und der Hybridantriebsvorrichtung, sodass ein Drehmoment (Leerlaufdrehmoment) auf die Antriebsräder übertragen wird. Bei einem Fahrzeug mit Automatikgetriebe löst er hierzu alternativ ein entsprechendes Bremspedal. Sind die Brennkraftmaschine und die elektrische Maschine miteinander wirkverbunden, so gleicht die elektrische Maschine, wie oben beschrieben, vorteilhafterweise die Trägheit (die langsame Reaktion) der Brennkraftmaschine aus, sodass letztere nicht durch eine plötzliche Drehmomentbeeinflussung abstirbt. Der besondere Vorteil des vorteilhaften Verfahrens liegt darin, dass die Brennkraftmaschine nicht im Bereich schlechter Wirkungsgrade betrieben werden muss, sodass der Kraftstoffverbrauch sowie ein Schadgasausstoß der Hybridantriebsvorrichtung gesenkt wird.The inventive method provides that the idle speed in each case proportionally from the internal combustion engine and the electric machine is effected. So it's planned that the idling speed of the hybrid drive device each proportionately caused by the internal combustion engine and the electric machine or is provided, for this purpose expediently a arranged between internal combustion engine and electric machine Clutch is closed / is. Under the idle speed of the hybrid drive device So here is a speed of the entire hybrid drive device to understand the different drive units, of the electric machine and the internal combustion engine, respectively can be influenced, which to reach the idle speed necessary torque according to the invention proportionally from the internal combustion engine and the electric machine made or made is, whereby the proportionate effect of the idle speed is carried out. In particular, it is at the idle speed of the hybrid drive device at a transmission input speed, with which a transmission of the vehicle is driven when a starting clutch between the hybrid drive device and the transmission is closed or is. By the proportionate Actuation of the internal combustion engine and the electric machine with target torques to reach the specified idle speed is both the dynamics and the efficiency of the overall system (the hybrid drive device) improved because now fast torque changes be effected by the electric machine and on the construction a torque reserve can be dispensed with. Where such torque changes can have different causes: This is how the torque the hybrid drive device, for example, influenced by that a cooling unit, for example, about a belt drive is driven by the internal combustion engine, switched on and thereby the torque of the internal combustion engine and thus the hybrid drive device influenced. Is from the hybrid drive device a quick torque increase required, for example, because the driver the accelerator pedal accordingly actuated, so can inertia the internal combustion engine balanced by the electric machine become. In rolling operation of the vehicle, the vehicle is at idle speed the hybrid drive device driven. The driver wants the vehicle From the state in the rolling motion, so he closes, for example by loosening the clutch pedal, the approach clutch between the transmission and the Hybrid drive device, so that a torque (idling torque) transferred to the drive wheels becomes. In a vehicle with automatic transmission, he solves this alternative corresponding brake pedal. Are the internal combustion engine and the electric Machine connected to each other, so is the electric machine, as described above, advantageously the inertia (the slow reaction) the internal combustion engine, so that the latter not by a sudden Torque interference dies. The particular advantage of the advantageous Procedure is that the internal combustion engine is not in the range bad efficiency must be operated, so fuel consumption as well as a pollutant emission of Hybrid drive device is lowered.
Vorteilhafterweise wird der jeweilige Anteil der Brennkraftmaschine und der elektrischen Maschine in Abhängigkeit eines aktuellen Betriebszustandes der Hybridantriebsvorrichtung vorgegeben. Dieser Betriebszustand kann beispielsweise durch die Betriebsart, wie zum Beispiel hybridischer Fahrbetrieb oder rein elektrischer Fahrbetrieb gekennzeichnet werden. Zweckmäßigerweise wird die Brennkraftmaschine in Bereichen günstiger Wirkungsgrade betrieben. Bei der Verteilung der Anteile wird hierbei also der Wirkungsgrad der Brennkraftmaschine priorisiert, sodass diese stets in Bereichen günstiger Wirkungsgrade läuft und der übrige Anteil von der elektrischen Maschine erbracht wird.advantageously, is the respective proportion of the internal combustion engine and the electric Machine in dependence a current operating state of the hybrid drive device specified. This operating state, for example, by the Operating mode, such as hybrid driving or pure electric driving operation are marked. Conveniently, the internal combustion engine is operated in areas of favorable efficiencies. In the distribution of shares, this is the efficiency the internal combustion engine prioritized so that they always cheaper in areas Efficiencies are running and the rest Proportion of the electric machine is provided.
Nach einer Weiterbildung der Erfindung wird bis zum Erreichen einer vorgebbaren Mindesttemperatur der Brennkraftmaschine der zu bewirkende Anteil der Brennkraftmaschine größer als der der elektrischen Maschine gewählt. Hierdurch wird die Brennkraftmaschine höher belastet, sodass sie in kürzerer Zeit ihre Betriebstemperatur erreicht. Bis dahin wird der Grundanteil im Wesentlichen von der Brennkraftmaschine gestellt. Die elektrische Maschine wird hierbei derart angesteuert, dass sie lediglich kleine dynamische Drehmomentänderungen ausgleicht.To a development of the invention is until reaching a predetermined Minimum temperature of the internal combustion engine, the proportion to be effected the internal combustion engine greater than that of the electric machine chosen. As a result, the internal combustion engine higher burden, so that they are shorter Time reaches its operating temperature. Until then, the basic share essentially provided by the internal combustion engine. The electric Machine is controlled in such a way that it only small dynamic torque changes balances.
Weiterhin ist vorgesehen, dass der jeweilige Anteil in Abhängigkeit von einem Ladezustand eines der elektrischen Maschine zugeordneten elektrischen Speichers vorgegeben wird. Dieser Speicher kann beispielsweise von einer oder mehreren wiederaufladbaren Batterien gebildet werden. Erreicht der Ladezustand des elektrischen Speichers einen maximalen Wert, so wird vorteilhafterweise der zu bewirkende Anteil der elektrischen Maschine erhöht, sodass der elektrische Speicher zumindest teilweise wieder entladen und eine Überladung verhindert wird. Gleichzeitig wird natürlich der zu bewirkende Anteil der Brennkraftmaschine verringert. Entsprechend werden die Anteile vorgegeben, wenn der Ladezustand des elektrischen Speichers einen kritischen Minimalwert erreicht. Dann wird vorteilhafterweise der zu bewirkende Anteil der Brennkraftmaschine hoch gewählt, sodass der elektrische Speicher nicht belastet oder aufgeladen wird. Im letzteren Fall wird dazu der zu bewirkende Anteil der Brennkraftmaschine derart hoch gewählt, dass die elektrische Maschine generatorisch betrieben werden kann. Die Anteile werden zweckmäßigerweise in Form von Drehmomentanforderungen der Brennkraftmaschine und der elektrischen Maschine vorgegeben. Weiterhin ist es denkbar, die Anteile in Abhängigkeit von einem Schadstoffausstoß (Emissionen), Notlauf-Eigenschaften, Geräuschentwicklung der Brennkraftmaschine und/oder einem Stellbereich der Antriebsaggregate zu bestimmen.Farther is provided that the respective proportion depending on a state of charge one of the electrical machine associated electrical storage is given. This memory may be, for example, one or several rechargeable batteries are formed. Reached the Charge state of the electrical storage a maximum value, so is advantageously the portion of the electrical Machine increases, so the electrical storage at least partially discharged again and an overload is prevented. At the same time, of course, the share to be effected the internal combustion engine reduced. Accordingly, the shares given when the state of charge of the electrical storage a reached critical minimum value. Then advantageously the chosen proportion of the engine high, so that the electrical storage is not loaded or charged. in the the latter case is the proportion of the internal combustion engine to be effected chosen so high that the electrical machine can be operated as a generator. The shares are expediently in the form of torque requirements of the internal combustion engine and the electrical machine specified. Furthermore, it is conceivable that Shares in dependence pollutant emissions, run-flat properties, noise the internal combustion engine and / or a control range of the drive units to determine.
Schließlich ist vorgesehen, dass dynamische oder hochdynamische Drehmomentänderungen der Hybridantriebsvorrichtung im Leerlauf durch die elektrische Maschine erfolgen beziehungsweise ausgeglichen werden. Wobei dynamische Drehmomentänderungen alternativ oder zusätzlich auch von der Brennkraftmaschine gestellt und/oder ausgeglichen werden können.Finally is provided that dynamic or highly dynamic torque changes the hybrid drive device idle by the electric Machine be made or compensated. Being dynamic torque changes alternatively or additionally also provided by the internal combustion engine and / or balanced can.
Ferner betrifft die Erfindung eine Hybridantriebsvorrichtung, insbesondere zur Durchführung des oben beschriebenen Verfahrens, mit mindestens einer Brennkraftmaschine und mindestens einer elektrischen Maschine und mit mindestens einer Leerlauf-Reglereinheit zum Einstellen einer Leerlaufdrehzahl der Hybridantriebsvorrichtung. Die vorteilhafte Hybridantriebsvorrichtung ist dadurch gekennzeichnet, dass die Leerlauf-Reglereinheit der Brennkraftmaschine und der elektrischen Maschine zugeordnet ist und diese derart ansteuert, dass die Leerlaufdrehzahl beziehungsweise das Drehmoment zum Erreichen der Leerlaufdrehzahl jeweils anteilig von der Brennkraftmaschine und der elektrischen Maschine bewirkt wird.Further The invention relates to a hybrid drive device, in particular to carry out the method described above, with at least one internal combustion engine and at least one electric machine and at least one idle control unit for adjusting an idle speed of the hybrid drive device.
