Description

Die vorliegende Erfindung betrifft ein Hybridfahrzeug gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to a hybrid vehicle according to the preamble of claim 1.

Unter einem „Hybridfahrzeug" wird ein Fahrzeug mit einem Verbrennungsmotor und mindestens einer elektrischen Maschine verstanden, wobei die elektrische Maschine dazu vorgesehen ist, Vortrieb zu erzeugen und in Schubphasen Bremsenergie zu rekuperieren. Unterschieden werden können so genannte Full-Hybrids, bei denen rein elektrisches Fahren, d. h. ohne verbrennungsmotorischen Antrieb möglich ist, und so genannte Mild-Hybrids, bei denen der Elektromotor lediglich zur Unterstützung des Verbrennungsmotors vorgesehen ist.Under a "hybrid vehicle" becomes a vehicle with an internal combustion engine and at least one electric machine understood, wherein the electric machine is provided, To generate propulsion and recuperate braking energy in coasting phases. Can be differentiated so-called full hybrids, in which purely electric driving, d. H. without internal combustion engine drive is possible, and so-called Mild hybrids in which the electric motor only in support of the Internal combustion engine is provided.

Bei einem Parallelhybrid ist der Elektromotor zwischen dem Verbrennungsmotor und dem Getriebe angeordnet, wobei das Drehmoment des Elektromotors dem Drehmoment, das von dem Verbrennungsmotor abgegeben wird, überlagert werden kann. Bei vielen derartigen Hybridtopologien ist zwischen dem Verbrennungsmotor und dem Elektromotor eine Reibkupplung angeordnet. Bei geöffneter Kupplung kann rein elektrisch gefahren werden, ohne dass der Verbrennungsmotor mitgeschleppt werden muss. Durch Schließen der Kupplung kann aus dem rein elektrischen Fahrbetrieb heraus der Verbrennungsmotor zugestartet werden. Der Zustart des Verbrennungsmotors soll möglichst so erfolgen, dass ein „Ruckeln" im Antriebsstrang sowie ein Leistungseinbruch vermieden werden. Eine derartige Anordnung ist sowohl konstruktiv als auch regelungstechnisch sehr kompliziert, wenn der Verbrennungsmotor ruckfrei zugestartet werden soll und ein Drehmomenteinbruch ausgeschlossen werden soll.at A parallel hybrid is the electric motor between the combustion engine and the transmission arranged, wherein the torque of the electric motor superimposed on the torque output by the internal combustion engine can be. In many such hybrid topologies is between the internal combustion engine and the electric motor arranged a friction clutch. With the clutch open can be driven purely electrically, without the internal combustion engine must be dragged along. By closing the clutch can from the purely electric driving out of the engine started become. The support of the internal combustion engine should as possible done so that a "bucking" in the drive train as well as a performance drop can be avoided. Such an arrangement is both constructive and control engineering very complicated, when the internal combustion engine is to be started smoothly and a torque drop should be excluded.

Aufgabe der Erfindung ist es, das oben beschriebene Konzept konstruktiv zu vereinfachen.task The invention is constructive, the concept described above to simplify.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.

Ausgangspunkt der Erfindung ist ein Hybridfahrzeug, mit einem Verbrennungsmotor, einem Getriebe und einer elektrischen Maschine, die in einem Antriebsstrangabschnitt zwischen dem Verbrennungsmotor und dem Getriebe angeordnet ist. Es handelt sich also um einen so genannten „Parallelhybrid", bei dem das Drehmoment der elektrischen Maschine dem vom Verbrennungsmotor abgegebenen Drehmoment überlagert werden kann. Um wahlweise ein rein elektrisches Fahren ohne Mitschleppen des Verbrennungsmotors zu ermöglichen, ist zwischen dem Verbrennungsmotor und einem Rotor der elektrischen Maschine eine Kupplung angeordnet. Durch Schließen der Kupplung kann der Verbrennungsmotor an die elektrische Maschine und an das mit der elektrischen Maschine gekoppelte Getriebe ankoppelt werden. Durch Öffnen der Kupplung kann der Verbrennungsmotor abgekoppelt werden, was ein rein elektrisches Fahren ermöglicht.starting point the invention is a hybrid vehicle with an internal combustion engine, a transmission and an electric machine operating in a driveline section is arranged between the internal combustion engine and the transmission. It is therefore a so-called "parallel hybrid" in which the torque the electric machine superimposed on the torque output by the internal combustion engine can be. To optionally a purely electric driving without entrainment to allow the internal combustion engine is between the combustion engine and a rotor of the electric Machine arranged a clutch. By closing the clutch, the internal combustion engine can to the electric machine and to the electric machine coupled gearboxes are coupled. By opening the clutch, the internal combustion engine can be disconnected, which allows a purely electric driving.

Der Kern der Erfindung besteht darin, anstatt einer Reibkupplung eine formschlüssige Trennkupplung vorzusehen, z. B. eine Klauenkupplung.Of the Core of the invention is instead of a friction clutch a positive Provide disconnect clutch, z. B. a dog clutch.

Zum Starten des Elektromotors ist vorzugsweise eine separate Zustarteinrichtung vorgesehen. Hierbei kann es sich beispielsweise um einen herkömmlichen Anlasser handeln.To the Starting the electric motor is preferably a separate Zustartinrichtung intended. This may be, for example, a conventional Starter act.

Nach einer Weiterbildung der Erfindung ist eine Steuerungseinrichtung zur Steuerung bzw. Betätigung der Kupplung vorgesehen. Die Steuereinrichtung überwacht die Drehzahldifferenz zwischen der Kurbelwelle des Verbrennungsmotors und der elektromaschinenseitigen Kupplungshälfte. Die Steuerungseinrichtung schließt die Kupplung nur dann, wenn die beiden Drehzahlen beider Kupplungshälften gleich sind bzw. wenn die Drehzahldifferenz einen vorgegebenen Wert nicht überschreitet.To a development of the invention is a control device for control or actuation provided the clutch. The controller monitors the speed difference between the crankshaft of the internal combustion engine and the electric machine side Coupling half. The controller closes the clutch only when the two speeds of both coupling halves are the same or if the speed difference does not exceed a predetermined value.

Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. 1 zeigt das Grundprinzip einer Hybridtopologie gemäß der Erfindung.In the following the invention will be explained in connection with the drawing. 1 shows the basic principle of a hybrid topology according to the invention.

1 zeigt eine Hybridtopologie 1 mit einem Verbrennungsmotor 2, dessen Kurbelwelle 3 über einen Torsionsdämpfer 4, z. B. ein Zweimassenschwungrad mit einer Eingangsseite 5 einer formschlüssigen Kupplung, z. B. eine Klauenkupplung 6 verbunden ist. Eine Ausgangsseite 7 der formschlüssigen Kupplung 6 ist über eine Welle 8 mit einem Eingang eines Getriebes 9 verbunden. Auf der Welle 8 sitzt ein Rotor 10 eines Elektromotors 11. 1 shows a hybrid topology 1 with an internal combustion engine 2 , its crankshaft 3 via a torsion damper 4 , z. B. a dual mass flywheel with an input side 5 a positive coupling, z. B. a dog clutch 6 connected is. An exit side 7 the positive coupling 6 is about a wave 8th with an input of a gearbox 9 connected. On the wave 8th a rotor sits 10 an electric motor 11 ,

Bei geschlossener Kupplung 6 kann das Fahrzeug wahlweise rein verbrennungsmotorisch oder gleichzeitig verbrennungsmotorisch und elektromotorisch angetrieben werden. Durch Öffnen der Kupplung 6 kann der Verbrennungsmotor 2 abgekoppelt werden und das Fahrzeug kann rein elektromotorisch angetrieben werden, wobei der Verbrennungsmotor vorzugsweise abgeschaltet wird. Für einen Übergang von rein elektromotorischem Antrieb auf verbrennungsmotorischen Antrieb muss der Verbrennungsmotor gestartet werden. Prinzipiell könnte der Verbrennungsmotor 2 durch die elektrische Maschine 11 gestartet werden. Dies ist jedoch regelungstechnisch äußerst aufwändig zu realisieren.With the clutch closed 6 If necessary, the vehicle can be driven purely by internal combustion engine or simultaneously by internal combustion engine and electric motor. By opening the clutch 6 can the internal combustion engine 2 be decoupled and the vehicle can be driven purely electric motor, the internal combustion engine is preferably switched off. For a transition from purely electric motor drive to internal combustion engine drive, the internal combustion engine must be started. In principle, the internal combustion engine could 2 through the electric machine 11 to be started. However, this is extremely complicated to implement in terms of control engineering.

Aus diesem Grund ist eine separate Startereinrichtung 12 für den Verbrennungsmotor 2 vorgesehen. Bei der Startereinrichtung 12 kann es sich beispielsweise um einen Anlasser im Riementrieb oder um einen Ritzelstarter handeln. Anstatt einer Reibkupplung 6 kann somit eine formschlüssige Kupplung 6 verwendet werden. Der Einsatz einer formschlüssigen Kupplung hat Vorteile hinsichtlich Bauraum, Gewicht und konstruktiver Komplexität. Zudem braucht keine hydraulische Betätigungsvorrichtung vorgesehen sein. Aufgrund der Formschlüssigkeit der Kupplung braucht zur Drehmomentübertragung keine Kraft aufgewendet werden, was in gewissem Umfang Verbrauchsvorteile bringt.For this reason, a separate starter device 12 for the internal combustion engine 2 intended. At the starter facility 12 it can be For example, to a starter in the belt drive or act on a pinion starter. Instead of a friction clutch 6 can thus be a positive coupling 6 be used. The use of a positive coupling has advantages in terms of space, weight and constructive complexity. In addition, no hydraulic actuator needs to be provided. Due to the positive engagement of the clutch, no force needs to be expended for transmitting torque, which provides some benefits in terms of fuel consumption.
