Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Antriebsanordnung, wie insbesondere einer Hybridantriebsanordnung eines Kraftfahrzeugs. The invention relates to a method for operating a drive arrangement, in particular a hybrid drive arrangement of a motor vehicle.

Kraftfahrzeuge mit Verbrennungsmotoren als Antriebsmotoren weisen eine Startvorrichtung auf, um mittels dieser den Verbrennungsmotor starten zu können, beispielsweise beim Beginn einer Fahrt oder in einer Start-Stopp-Phase, beispielsweise bei einem Ampelstopp. Solche Kraftfahrzeuge fahren nur unter einem Antriebsdrehmoment von dem Verbrennungsmotor. Motor vehicles with internal combustion engines as drive motors have a starting device in order to be able to start the internal combustion engine by means of this, for example at the start of a journey or in a start-stop phase, for example at a traffic light stop. Such vehicles drive only under a drive torque from the engine.

Bei so genannten Hybridfahrzeugen weist das Kraftfahrzeug eine Antriebsanordnung auf, die einen Verbrennungsmotor und einen Elektromotor aufweist, wobei je nach Leistung des Elektromotors und der Fähigkeit des rein elektrischen Fahrens man verschiedene Kategorien von Hybridfahrzeugen unterscheidet. Es sind so genannte Mikrohybridfahrzeuge, Mildhybridfahrzeuge und Fullhybridfahrzeuge bekannt. In so-called hybrid vehicles, the motor vehicle has a drive arrangement comprising an internal combustion engine and an electric motor, wherein different categories of hybrid vehicles are distinguished depending on the power of the electric motor and the capability of purely electric driving. So-called micro hybrid vehicles, mild hybrid vehicles and full hybrid vehicles are known.

Dabei kennzeichnet ein Hybridfahrzeug das Vorhandensein zweier unterschiedlicher Antriebsmotoren für den Fahrzeugantrieb, was bei sogenannten Mikrohybridfahrzeugen allerdings nicht der Fall ist. Mikrohybridfahrzeuge verfügen über eine Start-Stopp-Automatik und zusätzlich über eine Bremsenergierückgewinnung zum Laden der Starterbatterie. Der Elektromotor des Startergenerators wird jedoch nicht zum Antrieb des Fahrzeugs genutzt, sondern nur zum Starten des Verbrennungsmotors, welcher zum Antrieb des Fahrzeugs verwendet wird. Bei Mildhybridfahrzeugen unterstützt der Elektromotor den Verbrennungsmotor zur Leistungssteigerung. Die Bremsenergie kann zumindest teilweise elektrisch zurückgewonnen werden und die gespeicherte elektrische Energie kann zum Antrieb wieder genutzt werden. Vollhybridfahrzeuge sind mit ihren Elektromotoren mit Leistung von mehr als 20 kW pro Tonne Fahrzeuggewicht in der Lage, auch rein elektromotorisch zu fahren. In this case, a hybrid vehicle characterizes the presence of two different drive motors for the vehicle drive, which is not the case with so-called micro-hybrid vehicles. Micro hybrid vehicles have an automatic start-stop system and, in addition, brake energy recovery for charging the starter battery. However, the electric motor of the starter generator is not used to drive the vehicle, but only to start the engine, which is used to drive the vehicle. In mild hybrid vehicles, the electric motor supports the combustion engine to increase performance. The braking energy can be at least partially recovered electrically and the stored electrical energy can be used to drive again. Fully hybrid vehicles with their electric motors with a power of more than 20 kW per tonne of vehicle weight are able to drive purely by electric motor.

Bei den Mildhybridfahrzeugen wird der Verbrennungsmotor üblicherweise mittels eines Anlassers gestartet, wobei der Anlasser als Elektromotor mit einer kleineren Leistung ausgebildet ist, im Vergleich zu dem Elektromotor des Hybridantriebs. Dabei wird beim Anlassen des Verbrennungsmotors der Anlasser gestartet und so lange angetrieben, bis der Verbrennungsmotor auf einer Startdrehzahl ist, von welchem ein selbsttätiger Hochlauf der Drehzahl des Verbrennungsmotors bis zur Leerlaufdrehzahl erfolgen kann. Dieses Hochlaufen kann aufgrund des eingesetzten kleinen Elektromotors relativ lange dauern. Auch bei einem alternativen Einsatz eines Riemenscheibenstarters wäre die Hochlaufzeit des Verbrennungsmotors ebenso nicht sehr hoch. In the mild hybrid vehicles, the internal combustion engine is usually started by means of a starter, wherein the starter is designed as an electric motor with a smaller power, compared to the electric motor of the hybrid drive. In this case, when starting the internal combustion engine, the starter is started and driven until the internal combustion engine is at a starting rotational speed, from which an automatic run-up of the rotational speed of the internal combustion engine can take place up to idling speed. This run-up can take a relatively long time due to the small electric motor used. Even with an alternative use of a pulley starter, the acceleration time of the internal combustion engine would also not be very high.

Daher ist es die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Betreiben einer Antriebsanordnung zu schaffen, das einen schnelleren Hochlauf des Verbrennungsmotors erlaubt. Auch ist es die Aufgabe eine solche Antriebsanordnung zu schaffen, mittels welcher das erfindungsgemäße Verfahren zum beschleunigten Motorstart durchführbar ist. Therefore, it is the object of the present invention to provide a method for operating a drive arrangement, which allows a faster run-up of the internal combustion engine. It is also the object to provide such a drive arrangement, by means of which the inventive method for accelerated engine start is feasible.

Die Aufgabe zum Verfahren wird mit den Merkmalen von Anspruch 1 gelöst. The object of the method is achieved with the features of claim 1.

Ein Ausführungsbeispiel der Erfindung betrifft ein Verfahren zum Betreiben einer Antriebsanordnung mit einem Verbrennungsmotor und mit einem Elektromotor zum Antrieb eines Kraftfahrzeugs, wobei weiterhin ein Anlasser vorgesehen ist zum Anlassen des Verbrennungsmotors, wobei die Kurbelwelle des Verbrennungsmotors über einen Freilauf und eine Kupplung in Parallelschaltung mit einer Motorwelle des Elektromotors verbunden ist, welche mit einer Eingangswelle eines nachfolgenden Getriebes verbunden ist, wobei zum Anlassen des Verbrennungsmotors der Anlasser aktiviert wird und der Elektromotor aktiviert wird, wobei auch die Kupplung zur Drehmomentübertragung eingerückt wird. Dadurch wird der Verbrennungsmotor nicht nur mittels des Anlassers beschleunigt, sondern auch von dem Elektromotor, welcher für den Antrieb des Kraftfahrzeugs vorgesehen ist. Dadurch steht für das Beschleunigen ein höheres Drehmoment zur Verfügung, was ein schnelleres Starten bzw. Hochlaufen des Verbrennungsmotors bewirkt. An embodiment of the invention relates to a method for operating a drive assembly with an internal combustion engine and with an electric motor for driving a motor vehicle, wherein furthermore a starter is provided for starting the internal combustion engine, wherein the crankshaft of the internal combustion engine via a freewheel and a clutch in parallel with a motor shaft is connected to the electric motor, which is connected to an input shaft of a subsequent transmission, wherein for starting the internal combustion engine, the starter is activated and the electric motor is activated, wherein the clutch is engaged for transmitting torque. As a result, the internal combustion engine is accelerated not only by means of the starter, but also by the electric motor which is provided for driving the motor vehicle. As a result, a higher torque is available for the acceleration, which causes a faster starting or run-up of the internal combustion engine.

Dabei ist es vorteilhaft, wenn der Anlasser ab dem Stillstand des Verbrennungsmotors, also ab einer Drehzahl des Verbrennungsmotors von Null, aktiviert wird. Dadurch wird der Anlasser zumindest zu Beginn des Motorstartvorgangs eingesetzt, was zusammen mit dem Einsatz des Elektromotors zu einem beschleunigten Motorstart führt. It is advantageous if the starter from standstill of the internal combustion engine, ie from a speed of the engine of zero, is activated. As a result, the starter is used at least at the beginning of the engine starting process, which together with the use of the electric motor leads to an accelerated engine start.

Auch ist es vorteilhaft, wenn der Anlasser bis zu einer ersten Grenzdrehzahl des Verbrennungsmotors aktiviert wird. Die erste Grenzdrehzahl ist vorteilhaft eine Grenzdrehzahl, ab welcher der Verbrennungsmotor auch ohne Anlasserunterstützung hochlaufen kann. Dadurch kann der Anlasser einfacher gestaltet werden, weil er nicht zu höheren Drehzahlen aktiviert werden muss. It is also advantageous if the starter is activated up to a first limit speed of the internal combustion engine. The first limit speed is advantageously a limit speed, from which the engine can run up without starter support. As a result, the starter can be made simpler, because it does not have to be activated at higher speeds.

Auch ist es vorteilhaft, wenn der Anlasser bei Erreichen oder bei Überschreiten der vordefinierten ersten Grenzdrehzahl deaktiviert wird. Dadurch wird ebenfalls erlaubt, dass der Anlasser einfacher ausgebildet werden kann. It is also advantageous if the starter is deactivated upon reaching or exceeding the predefined first limit speed. This also allows the starter to be made simpler.

Besonders vorteilhaft ist es, wenn der Elektromotor ab dem Stillstand des Verbrennungsmotors, also ab einer Drehzahl des Verbrennungsmotors von Null, oder ab einer zweiten Grenzdrehzahl aktiviert wird. So wird erlaubt, dass zum Motorstart des Verbrennungsmotors der Anlasser durch den Elektromotor sofort ab Drehzahl gleich Null oder erst ab einer Grenzdrehzahl aktiviert wird und den Motorstart unterstützt. It is particularly advantageous if the electric motor is activated from a standstill of the internal combustion engine, that is, from a rotational speed of the internal combustion engine of zero, or from a second limiting rotational speed. Thus, it is allowed for the engine start of the internal combustion engine, the starter is activated by the electric motor immediately from zero speed or only from a limit speed and supports the engine start.

Dabei wird vorteilhaft ein schneller Motorstart erreicht, wenn der Elektromotor zumindest bis zum Erreichen der Leerlaufdrehzahl des Verbrennungsmotors aktiviert wird. In this case, a rapid engine start is advantageously achieved when the electric motor is activated at least until reaching the idling speed of the internal combustion engine.

Auch ist es vorteilhaft, wenn bei Aktivierung des Elektromotors die Kupplung eingerückt wird. Dadurch wird erreicht, dass der Elektromotor den Verbrennungsmotor antreiben kann, weil dadurch ein Drehmoment von dem Elektromotor auf den Verbrennungsmotor übertragbar ist. It is also advantageous if the clutch is engaged when the electric motor is activated. This ensures that the electric motor can drive the internal combustion engine, because thereby a torque from the electric motor to the internal combustion engine is transferable.

Weiterhin ist es vorteilhaft, wenn der Freilauf ab Erreichen der Leerlaufdrehzahl im Zugbetrieb sperrt. Furthermore, it is advantageous if the freewheel locks from reaching the idle speed in traction.

Die Aufgabe zur Antriebsanordnung wird mit den Merkmalen von Anspruch 9 gelöst. The object of the drive arrangement is achieved with the features of claim 9.

Ein Ausführungsbeispiel der Erfindung betrifft eine Antriebsanordnung für ein Kraftfahrzeug, mit einem Verbrennungsmotor und mit einem Elektromotor zum Antrieb des Kraftfahrzeugs, wobei weiterhin ein Anlasser vorgesehen ist zum Anlassen des Verbrennungsmotors, wobei die Kurbelwelle des Verbrennungsmotors über einen Freilauf und eine Kupplung in Parallelschaltung mit einer Motorwelle des Elektromotors verbunden ist, welche mit einer Eingangswelle eines nachfolgenden Getriebes verbunden ist, wobei mit der Antriebsanordnung ein erfindungsgemäßes Verfahren durchführbar ist. An embodiment of the invention relates to a drive assembly for a motor vehicle, with an internal combustion engine and with an electric motor for driving the motor vehicle, wherein furthermore a starter is provided for starting the internal combustion engine, wherein the crankshaft of the internal combustion engine via a freewheel and a clutch in parallel with a motor shaft the electric motor is connected, which is connected to an input shaft of a subsequent transmission, wherein with the drive arrangement, an inventive method is feasible.

Besonders vorteilhaft ist es, wenn die Kupplung eine Lamellenkupplung ist. Dadurch lassen sich bei kleinem radialen Bauraum auch größere Drehmomente übertragen. It is particularly advantageous if the clutch is a multi-plate clutch. As a result, larger torques can also be transmitted with a small radial installation space.

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung detailliert erläutert. In der Zeichnung zeigt: In the following the invention will be explained in detail by means of an embodiment with reference to the drawing. In the drawing shows:

1 eine schematische Darstellung einer Antriebsanordnung zur Durchführung eines erfindungsgemäßen Verfahrens zum Betreiben einer Antriebsanordnung, 1 a schematic representation of a drive arrangement for carrying out a method according to the invention for operating a drive arrangement,

2 eine schematische Darstellung zur Struktur einer Antriebsanordnung, und 2 a schematic representation of the structure of a drive assembly, and

3 ein Diagramm zur Erläuterung des erfindungsgemäßen Verfahrens. 3 a diagram for explaining the method according to the invention.

Die 1 zeigt in einer schematischen Darstellung eine Antriebsanordnung 1 mit einem Drehschwingungsdämpfer 2, der eingangsseitig mit der Kurbelwelle eines nicht dargestellten Verbrennungsmotors verbunden ist. Ausgangsseitig des Drehschwingungsdämpfers 2 ist der Verbrennungsmotor über einen Freilauf 3 sowie über eine Kupplung 4 mit der Eingangswelle 5 eines nachfolgenden Getriebes 6 verbunden. Die Kupplung 4 ist dabei als Lamellenkupplung ausgebildet, die in axialer Richtung eine Mehrzahl von Lamellen 7 aufweist, welche der Drehmomentübertragung dienen. Dabei ist radial außerhalb der Kupplung 4 ein Elektromotor 8 angeordnet, welcher dem Antrieb eines Kraftfahrzeugs dient, in welchem die Antriebsanordnung 1 angeordnet ist. The 1 shows a schematic representation of a drive assembly 1 with a torsional vibration damper 2 , which is the input side connected to the crankshaft of an internal combustion engine, not shown. Output side of the torsional vibration damper 2 is the internal combustion engine via a freewheel 3 as well as a clutch 4 with the input shaft 5 a subsequent transmission 6 connected. The coupling 4 is designed as a multi-plate clutch, which in the axial direction a plurality of fins 7 has, which serve the torque transmission. It is radially outside the clutch 4 an electric motor 8th arranged, which serves to drive a motor vehicle, in which the drive assembly 1 is arranged.

Der Elektromotor 8 ist mit seinem Rotor 9 mit der Eingangswelle 5 des Getriebes 6 verbunden. Über die Kupplung 4 kann der Elektromotor 8 beispielsweise im Schubbetrieb mit dem Verbrennungsmotor gekoppelt werden. So kann beispielsweise eine Motorbremse genutzt werden, da durch den nicht befeuerten Verbrennungsmotor ein Schleppmoment entsteht, wenn der Verbrennungsmotor dann unbefeuert angeschleppt wird. The electric motor 8th is with his rotor 9 with the input shaft 5 of the transmission 6 connected. About the clutch 4 can the electric motor 8th be coupled for example in overrun with the internal combustion engine. For example, an engine brake can be used as a drag torque is created by the non-fired internal combustion engine when the engine is then towed unbefeuert.

Die 2 zeigt die Antriebsanordnung 10 in einer schematischen Darstellung. Dabei ist ein Verbrennungsmotor 11 vorgesehen, mittels welchem das Kraftfahrzeug, in welcher die Antriebsanordnung angeordnet ist, angetrieben werden kann. Der Verbrennungsmotor 11 kann von einem vorgesehen Anlasser 12 angelassen werden. Dabei kann der Anlasser als Zustarteinrichtung ein elektromotorischer Anlasser, der unmittelbar mit der Kurbelwelle des Verbrennungsmotors verbunden ist, sein oder er kann auch als ein Riemenstarter ausgebildet sein, der über einen Riemen 13 mit der Kurbelwelle des Verbrennungsmotors 11 gekoppelt ist. The 2 shows the drive assembly 10 in a schematic representation. Here is an internal combustion engine 11 provided, by means of which the motor vehicle, in which the drive arrangement is arranged, can be driven. The internal combustion engine 11 can be provided by a starter 12 to be started. In this case, the starter can be an electric motor starter, which is connected directly to the crankshaft of the internal combustion engine, as a starter or it can also be designed as a belt starter, which via a belt 13 with the crankshaft of the internal combustion engine 11 is coupled.

Weiterhin ist ein Elektromotor 14 vorgesehen, wobei der Verbrennungsmotor 11 mit dem Elektromotor 14 über einen Freilauf 15 und eine dazu parallel geschaltete Kupplung 16 verbunden bzw. verbindbar ist. Der Elektromotor 14 ist mit einer Eingangswelle 18 eines nachgeschalteten Getriebes 17 verbunden. Furthermore, an electric motor 14 provided, the internal combustion engine 11 with the electric motor 14 over a freewheel 15 and a parallel clutch 16 connected or connectable. The electric motor 14 is with an input shaft 18 a downstream transmission 17 connected.

Dabei stellt die Antriebsanordnung beispielsweise einen Mildhybrid dar, umfassend den Verbrennungsmotor 11 mit seinem Anlasser, wobei der Verbrennungsmotor gemeinsam mit dem Elektromotor 14 den nachgeschalteten Antriebsstrang antreiben kann, wobei zwischen dem Verbrennungsmotor 11 und dem Elektromotor 14 ein Freilauf 15 sowie eine beispielsweise als Lamellenkupplung ausgebildete Kupplung parallel geschaltet sind. The drive arrangement represents, for example, a mild hybrid comprising the internal combustion engine 11 with its starter, the internal combustion engine being in common with the electric motor 14 can drive the downstream drive train, being between the engine 11 and the electric motor 14 a freewheel 15 and a trained example as a multi-plate clutch clutch are connected in parallel.

Bei laufendem Verbrennungsmotor 11 treibt dieser über den Freilauf 15 den Antriebsstrang an, gegebenenfalls zusammen mit dem Elektromotor 14. Im Schubbetrieb des Kraftfahrzeuges, beispielsweise bei einer Bergabfahrt, kann durch Einrücken der Kupplung der unbefeuerte bzw. stillstehende Verbrennungsmotor 11 in den Antriebsstrang eingekoppelt werden, und so als Motorbremse wirken. With the internal combustion engine running 11 this drives over the freewheel 15 the drive train, possibly together with the electric motor 14 , In overrun operation of the motor vehicle, for example when driving downhill, the unburned or stationary internal combustion engine can be engaged by engaging the clutch 11 be coupled into the drive train, and act as an engine brake.

Gemäß dem erfindungsgemäßen Verfahren ist vorgesehen, dass der Verbrennungsmotor 11 nicht alleine mit dem Anlasser 12 gestartet wird, sondern dass zusätzlich noch der Elektromotor 14 eingesetzt wird, welcher über die eingerückte Kupplung 16 den Verbrennungsmotor 11 zusammen mit dem Anlasser startet. Durch das Drehmoment des Elektromotors 14, das über die eingerückte Kupplung 16 zusätzlich zum Anlasser 12 in den Verbrennungsmotor 11 eingeleitet wird, kann das Hochlaufen des Verbrennungsmotors 11 beschleunigt werden. According to the method of the invention, it is provided that the internal combustion engine 11 not alone with the starter 12 is started, but that additionally the electric motor 14 is used, which on the engaged clutch 16 the internal combustion engine 11 starts together with the starter. By the torque of the electric motor 14 That's about the engaged clutch 16 in addition to the starter 12 in the internal combustion engine 11 is initiated, the run-up of the engine 11 be accelerated.

Ab nM = 0 bis nM = erste Grenzdrehzahl nG1 wird der Anlasser auf RS = an gesetzt und der Verbrennungsmotor läuft mit steigender Drehzahl an. Bei der ersten Grenzdrehzahl nG1 wird der Anlasser abgeschaltet bzw. deaktiviert, es gilt: RS = aus. Die Kupplung bleibt ausgerückt und der Freilauf ist nicht aktiv. Ab der Drehzahl n = nG1 steigt die Motordrehzahl nM bis zur Leerlaufdrehzahl nL an. Ab Erreichen der Leerlaufdrehzahl nL wird der Freilauf aktiv. Die Zeitdauer für den Motorstart ist t1.
