Aufgabe der Erfindung ist, für einen Antriebsstrang mit Riemenscheibengenerator ein Verfahren vorzuschlagen, welches insbesondere in Change-of-mind-Situationen bei einsetzender Stillsetzung der Brennkraftmaschine eine schnelle und komfortable Wiederinbetriebnahme dieser ermöglicht. The object of the invention is to propose a method for a drive train with a pulley generator, which enables rapid and comfortable recommissioning of these in particular in change-of-mind situations when the engine is stopped.
Die Aufgabe wird durch ein Verfahren nach Anspruch 1 gelöst. Die Ansprüche 2 bis 9 enthalten vorteilhafte Ausführungsformen des Anspruchs 1.The object is achieved by a method according to claim 1. The claims 2 to 9 contain advantageous embodiments of claim 1.
In einem vorteilhaften Verfahren zur Steuerung eines Antriebsstrangs mit einer im Start-/Stopp-Betrieb betreibbaren Brennkraftmaschine und einem mit einer Kurbelwelle der Brennkraftmaschine über einen Riementrieb verbundenen Riemenscheibengenerator mit zwei schaltbaren Übersetzungen wird bei einer Umsteuerung einer geplanten beziehungsweise eingeleiteten Stillsetzung der Brennkraftmaschine mit bereits resultierenden Drehzahlen unterhalb einer Leerlaufdrehzahl in einen Weiterbetrieb die Übersetzung des Riemenscheibengenerators abhängig von zumindest einem Betriebsparameter des Antriebsstrangs gewählt und die Brennkraftmaschine mittels des Riemenscheibengenerators bei gewählter Übersetzung zumindest auf Leerlaufdrehzahl beschleunigt. Die Übersetzungen werden hierbei in bevorzugter Weise von einem schaltbaren Planetengetriebe bereitgestellt. In einem derartigen schaltbaren Planetengetriebe kann beispielsweise mittels eines in beide Richtungen schaltbaren Freilaufs beispielsweise eine direkte Übersetzung 1:1 und eine Übersetzung der Elektromaschine in Form des Riemenscheibengenerators von beispielsweise 3:1 ins Schnelle geschaltet werden. Der Riemenscheibengenerator ist hierbei bevorzugt in einen vorhandenen Riementrieb mit Nebenaggregaten integriert. Die Steuerung der Übersetzung abhängig von Betriebsparametern des Antriebsstrangs erfolgt dabei mit dem Ziel einer schnellen Wiederaktivierung der Brennkraftmaschine ohne eine hohe Belastung des Antriebsstrangs, beispielsweise der Nebenaggregate und dergleichen. In an advantageous method for controlling a drive train with an operable in start / stop operation internal combustion engine and a crankshaft of the internal combustion engine via a belt drive pulley generator with two shiftable ratios is at a reversal of a planned or initiated shutdown of the internal combustion engine with already resulting speeds selected under an idle speed in a further operation, the translation of the pulley generator depending on at least one operating parameter of the drive train and the internal combustion engine accelerates by means of the pulley generator with selected gear ratio at least to idle speed. The translations are provided here in a preferred manner by a switchable planetary gear. In such a switchable planetary gear, for example, by means of a switchable in both directions freewheel, for example, a direct ratio 1: 1 and a translation of the electric machine in the form of the pulley generator, for example, 3: 1 are switched to fast. The pulley generator is preferably integrated in an existing belt drive with ancillary units. The control of the translation depending on operating parameters of the drive train is carried out with the aim of rapid re-activation of the internal combustion engine without high load on the drive train, such as the ancillaries and the like.
Es hat sich dabei als vorteilhaft erwiesen, die Übersetzung zwischen Brennkraftmaschine und dem diese zum Wiederstart antreibenden Riemenscheibengenerator wenn möglich direkt oder mit geringer Übersetzung ins Schnelle zu wählen, um einen schnellen Wiederstart zu ermöglichen. Besteht dabei durch das an dem Riemenscheibengenerator anliegende hohe Moment eine Gefährdung von Bauteilen oder Elementen des Antriebsstrangs, wird ein geringfügig längerer jedoch immer noch schnellerer Wiederstart durch Wahl eines ins Schnelle übersetzten Riemenscheibengenerators in Kauf genommen. It has proven to be advantageous in this case to choose the ratio between the internal combustion engine and the pulley generator which drives it for restarting, if possible directly or with a low gear ratio, in order to enable a quick restart. If there is a danger of components or elements of the drive train due to the high torque applied to the pulley generator, a slightly longer but still faster restart is accepted by selecting a pulley generator that has been translated quickly.
Insbesondere hat sich eine Auswahl der Übersetzung in Antriebssträngen mit einem Zweimassenschwungrad als vorteilhaft erwiesen. Hierbei kann abhängig von einer Belastung des Zweimassenschwungrads, beispielsweise in Form eines Schwingwinkels der Schwungmassen gegeneinander eine entsprechende Übersetzung geschaltet werden, um ein Moment des Riemenscheibengenerators entsprechend einzustellen. Durch die Vermeidung von so genannten Impacts durch Verwendung des vorgeschlagenen Verfahrens kann das Zweimassenschwungrad einfacher, beispielsweise einstufig ausgebildet werden. Wird beispielsweise bei direkter Übersetzung ein zu hohes Moment des Riemenscheibengenerators und damit ein zu größer Schwingwinkel erwartet, wird das Getriebe wie Planetengetriebe ins Schnelle geschaltet. Der Schwingwinkel kann mittels eingangsseitigen und ausgangsseitigen Drehzahl- oder Drehwinkelsensoren ermittelt werden. Andererseits muss vermieden werden, sogenannte Resonanzhänger während des Wiederstarts der Brennkraftmaschine zu vermeiden, wenn das Moment des Riemenscheibengenerators zu gering ist. In particular, a selection of the transmission in power trains with a dual mass flywheel has proven to be advantageous. In this case, depending on a load of the dual mass flywheel, for example in the form of a swing angle of the flywheel masses against each other, a corresponding translation can be switched to adjust a moment of the pulley generator accordingly. By avoiding so-called impacts by using the proposed method, the dual-mass flywheel can be made simpler, for example, in one stage. If, for example, a too high torque of the pulley generator and thus too large in direct translation Oscillation angle expected, the transmission is switched as planetary gearboxes. The oscillation angle can be determined by means of input-side and output-side speed or rotation angle sensors. On the other hand, it must be avoided to avoid so-called resonance hanger during the restart of the internal combustion engine, if the moment of the pulley generator is too low.
Das Moment des Riemenscheibengenerators wird durch weitere Betriebsparameter wie beispielsweise dem Ladezustand und/oder der Restkapazität eines den Riemenscheibengenerator speisenden Akkumulators und/oder der durch die Nebenaggregate, beispielsweise eines Klimakompressors abgeforderten Last beeinflusst. Gemäß dem erfinderischen Gedanken werden daher die Übersetzungen abhängig von diesen Betriebsparametern geschaltet. Ist beispielsweise die Last der Nebenaggregate durch Betrieb des Klimakompressors hoch und/oder die Leistung des Riemenscheibengenerators beispielsweise aufgrund geringer Restkapazität des Akkumulators infolge geringer Temperaturen und/oder geringer Ladung begrenzt, beispielsweise kleiner 40% seiner Maximalleistung, wird bevorzugt eine direkte oder gering ins Schnelle übersetzende Getriebestufe gewählt, da beispielsweise der Schwingwinkel des Zweimassenschwungrads in diesem Fall gering bleibt. Ist die Last gering und/oder die mögliche Leistung des Riemenscheibengenerators hoch, beispielsweise größer gleich 40% seiner Maximalleistung, wird das Moment des Riemenscheibengenerators durch Wahl einer Übersetzung ins Schnelle begrenzt. Es hat sich beispielsweise als vorteilhaft erwiesen, ein Moment von 50 Nm bis 80 Nm anzustreben, um einerseits Resonanzhänger des Zweimassenschwungrads, bei denen ein Start unmöglich ist, und andererseits eine Überlastung des Zweimassenschwungrads durch hohe Schwingwinkel zu vermeiden.The torque of the pulley generator is influenced by further operating parameters such as the state of charge and / or the residual capacity of a battery supplying the pulley generator and / or the load demanded by the ancillary components, for example an air conditioning compressor. According to the inventive concept, therefore, the translations are switched depending on these operating parameters. For example, if the load of the ancillaries by operation of the air compressor high and / or the power of the pulley generator limited due to low residual capacity of the battery due to low temperatures and / or low charge, for example, less than 40% of its maximum power, is preferably a direct or low translating quickly Gear selected, since, for example, the swing angle of the dual-mass flywheel remains low in this case. If the load is low and / or the possible power of the pulley generator is high, for example greater than or equal to 40% of its maximum power, the momentum of the pulley generator is limited by the choice of a gear ratio. For example, it has proven to be advantageous to aim for a torque of 50 Nm to 80 Nm in order, on the one hand, to avoid resonance hoppers of the dual-mass flywheel in which starting is impossible and, on the other hand, overloading of the dual-mass flywheel by high angles of oscillation.
Um die Betriebsparameter eindeutig zur Steuerung der Auswahl einer Übersetzung während einer Umsteuerung heranziehen zu können, können für diese Grenzwerte festgelegt werden, welche über Lebensdauer konstant oder einer Entwicklung der Betriebsparameter über Betriebsdauer adaptiert werden können. Weiterhin können über mehrere Betriebsparameter, beispielsweise die Last der Nebenaggregate, den Ladungszustand des Akkumulators, die Kenndaten des Zweimassenschwungrads und dergleichen laufend aktualisierte Kennfelder angelegt werden, aufgrund derer in einer Change-of-mind-Situation die entsprechende Übersetzung eingelegt wird.In order to be able to use the operating parameters unambiguously to control the selection of a ratio during a reversal, it is possible to specify for these limit values which can be adapted over the service life or a development of the operating parameters over the operating period. Furthermore, over several operating parameters, such as the load of the ancillaries, the charge state of the accumulator, the characteristics of the dual mass flywheel and the like continuously updated maps are created, due to which the corresponding translation is inserted in a change-of-mind situation.
Es hat sich gezeigt, dass der Riemenscheibengenerator in den meisten Fällen ausreichend leistungsstark ist, die Brennkraftmaschine während eines Wiederstarts auf Leerlaufdrehzahl ohne Einspritzung hoch zu schleppen. Auf diese Weise werden für das Zweimassenschwungrad belastende Drehungleichförmigkeiten bei Drehzahlen unter der Leerlaufdrehzahl vermieden. Es wird daher vorgeschlagen, Einspritzvorgänge der Brennkraftmaschine unterhalb der Leerlaufdrehzahl und gegebenenfalls eine auszuwählende Übersetzung von einem effektiv zur Verfügung stehenden Moment des Riemenscheibengenerators zu steuern.It has been found that in most cases the pulley generator is sufficiently powerful to tow the engine up to idle speed without injection during a restart. In this way, for the dual mass flywheel polluting rotational irregularities are avoided at speeds below idle speed. It is therefore proposed to control injection processes of the internal combustion engine below the idling speed and optionally a ratio to be selected from an effectively available torque of the pulley generator.
Das vorgeschlagene Verfahren wird bevorzugt erst bei Drehzahlen der Brennkraftmaschine gestartet, bei denen ein selbstständiger Wiederstart der Brennkraftmaschine durch Einspritzvorgänge nicht mehr möglich ist. Dies bedeutet, dass das Verfahren bei Drehzahlen kleiner als einer vorgegebenen oder vorgebbaren Drehzahlschwelle durchgeführt wird. The proposed method is preferably started only at speeds of the internal combustion engine, in which an independent restart of the internal combustion engine by injection operations is no longer possible. This means that the method is carried out at speeds less than a predetermined or predefinable speed threshold.
