Description

Verfahren zum Steuern und/oder Regeln einer Hybridantriebsanordnunq eines Method for controlling and / or controlling a hybrid drive arrangement of a
Fahrzeugesvehicle
Die vorliegende Erfindung betrifft ein Verfahren zum Steuern und/oder Regeln einer Hybridantriebsanordnung eines Fahrzeuges der im Oberbegriff des Patentanspruches 1 näher definierten Art.The present invention relates to a method for controlling and / or regulating a hybrid drive arrangement of a vehicle of the type defined in detail in the preamble of claim 1.
Aus der Fahrzeugtechnik sind Hybridantriebsanordnungen für Fahrzeuge bekannt. Bei der bekannten Hybridantriebsanordnung umfasst der Antriebsstrang des Fahrzeuges einen Verbrennungsmotor, der über eine Kupplung mit einer Eingangswelle eines Getriebes mit variabler Übersetzung koppelbar ist. Ferner ist der Eingangswelle zumindest eine elektrische Maschine zugeordnet, welche zwischen einem generatorischen oder motorischen Betrieb umschaltbar ist. Demzufolge kann die Elektromaschine im motorischen Betrieb zum Antrieb des Fahrzeuges und im generatorischen Betrieb zum Aufladen eines Energiespeichers verwendet werden.From vehicle technology, hybrid drive arrangements for vehicles are known. In the known hybrid drive arrangement, the drive train of the vehicle comprises an internal combustion engine which can be coupled via a clutch to an input shaft of a transmission with variable transmission. Furthermore, the input shaft is assigned at least one electrical machine, which can be switched between a regenerative or motor operation. Accordingly, the electric machine can be used in motor operation for driving the vehicle and in regenerative operation for charging an energy storage.
Bei bestimmten operativen Hybridfunktionen ist es notwendig, den Kraft- fluss zwischen dem Getriebeeingang und dem Abtrieb zu unterbrechen, indem der Antriebsstrang geöffnet wird. Nach dem beenden der Hybridfunktion wird der Antriebsstrang wieder geschlossen. Es hat sich gezeigt, dass dazu eine gewisse Zeit erforderlich ist. Dies mindert jedoch den Komfort.For certain operational hybrid functions, it is necessary to interrupt the flow of power between the transmission input and the output by opening the drive train. After completing the hybrid function, the powertrain is closed again. It has been shown that this requires a certain amount of time. However, this reduces the comfort.
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren der eingangs beschriebenen Gattung vorzuschlagen, bei dem die erforderliche Zeit zum Schließen des geöffneten Antriebsstranges verkürzt wird.The invention is based on the object to propose a method of the type described above, in which the time required to close the open drive train is shortened.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den jeweiligen Unteransprüchen. Demgemäß wird ein Verfahren zum Steuern und/oder Regeln einer Hybridantriebsanordnung für ein Fahrzeug mit zumindest einem Verbrennungsmotor und zumindest einer Elektromaschine vorgeschlagen, welche über wenigstens eine Kupplung mit einem ein Getriebe mit variabler Übersetzung umfassenden Antriebsstrang zum Antrieb des Fahrzeuges koppelbar sind, wobei über ein Steuergerät zum Ausführen zumindest einer vorbestimmten Hybridfunktion der Antriebsstrang geöffnet wird, welches durch das Setzen eines Bits „Getriebe öffnen" durch das Steuergerät erfolgen kann. Erfindungsgemäß kann das Getriebe bei geöffnetem Antriebsstrang durch das Steuergerät während einer vorbestimmten aktivierten Hybridfunktion aktiv gehalten werden.This object is achieved by the features of claim 1. Further advantageous embodiments will be apparent from the respective dependent claims. Accordingly, a method is proposed for controlling and / or regulating a hybrid drive arrangement for a vehicle having at least one internal combustion engine and at least one electric machine, which can be coupled via at least one clutch to a transmission comprising a variable ratio transmission for driving the vehicle, wherein a control device In order to carry out at least one predetermined hybrid function, the drive train is opened, which can be effected by the setting of a bit "open gearbox" by the control unit According to the invention, the transmission can be kept active with the drive train open by the control device during a predetermined activated hybrid function.
Dies erfolgt beispielsweise dadurch, dass das Steuergerät vorzugsweise gleichzeitig oder auch verzögert mit dem Setzen des Bits „Getriebe öffnen" auch ein Bit „Getriebe bleibt aktiv" setzt. Auf diese Weise kann durch das erfindungsgemäße Verfahren das Steuergerät den Antriebsstrang nach dem Beenden der Hybridfunktion schnellstmöglich wieder schließen.This is done, for example, in that the control unit preferably simultaneously or also with the setting of the bit "gear open" also a bit "gear remains active" sets. In this way, by means of the method according to the invention, the control unit can close the drive train as soon as possible after the hybrid function has ended.
Im Rahmen einer möglichen Ausführung der vorliegenden Erfindung kann vorgesehen sein, das bei einem automatisierten Getriebe und bei einem integrierten Starter/Generator als Elektromaschine mit einer Kupplung das Getriebe in den Neutralzustand geschaltet wird, wobei die Schaltgassen- Position nachgeführt wird. Somit kann das Schließen des Antriebsstranges nach beendeter Hybridfunktion ohne Verzögerungen erfolgen, da sich das Getriebe bereits vor der zu schaltenden Schaltgasse befindet.As part of a possible embodiment of the present invention can be provided that in an automated transmission and an integrated starter / generator as an electric machine with a clutch, the transmission is switched to the neutral state, wherein the shift gate position is tracked. Thus, the closing of the drive train can be done without delays after completion of the hybrid function, since the transmission is already in front of the shift gate to be switched.
Wenn beispielsweise zwei Kupplungen im Antriebsstrang vorgesehen sind, wobei die erste Kupplung zum Beispiel zwischen dem Verbrennungsmotor und der Elektromaschine und die zweite Kupplung zum Beispiel zwischen der Elektromaschine und dem Getriebeeingang vorgesehen ist, kann das Getriebe die zwischen der Elektromaschine und dem Getriebeeingang vorgesehene Kupplung zumindest in der Nähe des Anlegepunktes der Kupplung halten, damit der Antriebsstrang bei beendeter Hybridfunktion schnell wieder geschlossen werden kann.For example, if two clutches are provided in the powertrain, with the first clutch being provided between, for example, the engine and the electric machine, and the second clutch being provided between, for example, the electric machine and the transmission input, the transmission may hold the provided between the electric machine and the transmission input clutch at least in the vicinity of the application point of the clutch, so that the drive train can be quickly closed again when the hybrid function is completed.
Im Rahmen einer weiteren Ausführung der vorliegenden Erfindung kann vorgesehen sein, dass bei einem Automatgetriebe und bei einem integrierten Starter/Generator als Elektromaschine mit einer Kupplung das Getriebe mittels zumindest einer getriebeinternen Kupplung geöffnet wird, wobei der Zustand der internen Kupplung zumindest in der Nähe des Anlegepunktes der Kupplung gehalten wird. Auf diese Weise wird auch bei dieser Ausführung des Getriebes ein möglichst schnelles Schließen des Antriebsstranges nach beendeter Hybridfunktion realisiert.In a further embodiment of the present invention can be provided that in an automatic transmission and an integrated starter / generator as an electric machine with a clutch, the transmission is opened by means of at least one internal transmission clutch, wherein the state of the internal clutch at least in the vicinity of the application point the clutch is held. In this way, the fastest possible closing of the drive train after completion of the hybrid function is realized in this embodiment of the transmission.
Unabhängig von der jeweiligen Ausführung der Hybridantriebsanordnung kann das erfindungsgemäße Verfahren universell eingesetzt werden. Somit kann das vorgeschlagene Verfahren bei vielen Systemen wieder verwendet werden, ohne dass aufwändige Umgestaltungen und Abstimmungen erforderlich sind.Regardless of the particular embodiment of the hybrid drive arrangement, the inventive method can be used universally. Thus, the proposed method can be reused in many systems without the need for elaborate conversions and adjustments.
Vorzugsweise kann das Getriebe bei einem Direktstart des Verbrennungsmotors, bei einem Schwungstart des Verbrennungsmotors, einem aktiven Stopp des Verbrennungsmotors und/oder beim Laden eines Energiespeichers im Stillstand des Fahrzeuges durch das Steuergerät aktiv gehalten werden, um das schnelle Schließen des geöffneten Antriebsstranges realisieren zu können. Es sind auch andere Hybridfunktionen möglich, bei denen das schnelle Schließen des Antriebsstranges realisiert werden kann.Preferably, the transmission can be kept active during a direct start of the internal combustion engine, during a swing start of the internal combustion engine, an active stop of the internal combustion engine and / or when charging an energy storage device at standstill of the vehicle by the control unit to realize the rapid closing of the open drive train can. There are also other hybrid functions possible in which the rapid closing of the drive train can be realized.
Die erfindungsgemäß vorgeschlagene Hybridantriebsanordnung und das Verfahren können bevorzugt bei parallelhybrid Anthebssytemen beispielsweise für Stadtbusse, Verteiler-Lastkraftwagen und Transporter eingesetzt werden. Es sind auch andere Einsatzgebiete denkbar. The inventively proposed hybrid drive assembly and the method may preferably in parallel hybrid Anthebssytemen example for city buses, distribution trucks and vans. There are also other applications conceivable.
