Abstract

The vehicle (2) has an electrical drive (5), with which an internal combustion engine is coupled by an automatically or manually operated standard transmission (3) with a drive line working on a drive wheel. The electric drive has non-effective connection guided over the standard transmission with the drive line and/or with wheels of the vehicle, if a gear ratio or reverse gear of the drive is laid. The starting of the vehicle is implemented by the electrical drive and without the gear ratio. An independent claim is also included for a method of operating the motor vehicle.

Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem Verbrennungsmotor, einem elektrischen Antrieb und einem Getriebe gemäß Anspruch 1.The Invention relates to a motor vehicle with an internal combustion engine, an electric drive and a transmission according to claim 1.

Fahrzeuge mit Hybridantrieben, welche automatische oder manuell schaltbare Getriebe enthalten, sind an sich bekannt.vehicles with hybrid drives, which are automatic or manually switchable Gear included, are known per se.

Die Erfindung beschäftigt sich mit dem Problem, dass das Anfahren eines Kraftfahrzeuges zu Kupplungsverschleiß führt und die zunehmende Anzahl der Getriebestufen ein nicht zu vernachlässigender Kostenfaktor bei der Herstellung eines Getriebes darstellt.The Invention busy with the problem that the start of a motor vehicle leads to clutch wear and the increasing number of gear stages a not negligible Cost factor in the production of a transmission represents.

Die Erfindung hat sich daher die Aufgabe gestellt, diese Nachteile bekannter Hybridfahrzeuge zu beseitigen.The The invention therefore has the task of these disadvantages known To eliminate hybrid vehicles.

Diese Aufgabe wird erfindungsgemäß durch das Kraftfahrzeug gemäß Anspruch 1 gelöst, bei dem das Kraftfahrzeug zumindest einen Verbrennungsmotor und zumindest einen elektrischen Antrieb aufweist, bei dem der Verbrennungsmotor über ein automatisches oder manuell bedienbares Schaltgetriebe mit dem auf die Antriebsräder wirkenden Antriebsstrang gekoppelt ist, und wobei der elektrische Antrieb zumindest, wenn die erste Gangstufe oder der Rückwärtsgang des Getriebes eingelegt ist, eine nicht über ein schaltbares Getriebe geführte Wirkverbindung mit dem Antriebsstrang hat.These The object is achieved by the Motor vehicle according to claim 1 solved, in which the motor vehicle at least one internal combustion engine and has at least one electric drive, wherein the internal combustion engine via a automatic or manually operated manual transmission with the the drive wheels Acting powertrain is coupled, and wherein the electric Drive at least when the first gear or the reverse gear of the transmission is engaged, not a switchable transmission guided Has active connection with the drive train.

Es können auch mehrere Elektromotoren vorgesehen sein, wobei es sinnvoll sein kann, einen, zwei, drei oder vier Elektromotoren vorzusehen. Im Falle der mehrfach vorgesehenen Elektromotoren kann auf vorhandene Differentialgetriebe verzichtet werden.It can also be provided several electric motors, where it makes sense can provide one, two, three or four electric motors. In the event of the multiple-envisaged electric motors can on existing differential gear be waived.

Der elektrische Antrieb wird bevorzugt aus einem elektrischen Speicher und/oder aus einem mit dem Verbrennungsmotor gekoppelten Generator gespeist.Of the Electric drive is preferred from an electrical storage and / or from a generator coupled to the internal combustion engine fed.

Die Erfindung bietet die Möglichkeit, das Anfahren aus dem Stand ohne Zuhilfenahme einer Kupplung mit Hilfe des elektrischen Antriebs durchzuführen. Hierdurch wird vorteilhafterweise der Kupplungsverschleiß drastisch reduziert.The Invention offers the possibility the starting from the state without the aid of a clutch with To carry out help of the electric drive. This will be advantageous the clutch wear drastically reduced.

Es ist außerdem möglich, dass Anfahren des Kraftfahrzeugs ohne die erste Gangstufe durchzuführen. Das Getriebe wird während des Anfahrvorgangs nicht benötigt. Erst bei höheren Geschwindigkeiten kann dann im zweiten Gang bzw. ggf. in einem höheren Gang gefahren werden.It is also possible, starting the motor vehicle without performing the first gear. The Transmission is during of the starting process is not required. Only at higher Speeds can then in second gear or possibly in a higher gear be driven.

Ein weiterer Vorteil der Erfindung besteht darin, dass ein. Rückwärtsgang innerhalb des Getriebes entfallen kann. Durch einfaches elektrisches Umschalten des elektrischen Antriebs kann die Funktion des Rückwärtsfahrens auf besonders einfache Weise nur durch den elektrischen Antrieb ohne ein Getriebe bereitgestellt werden.One Another advantage of the invention is that a. reverse gear can be omitted within the transmission. By simple electric Switching the electric drive may be the function of reversing in a particularly simple way only by the electric drive be provided without a gear.

Weitere Vorteile ergeben sich dadurch, dass die Kupplung nicht mehr so groß ausgelegt sein muss, wie in Kraftfahrzeugen, die die weiter oben beschriebene Erfindung nicht nutzen. Die Kupplung kann daher räumlich, funktional und ge wichtsmäßig reduziert werden. Das gleiche gilt für den vom Getriebe weiter führenden Antriebstrang, welcher gemäß der Erfindung ein geringeres maximales Drehmoment übertragen muss.Further Benefits result from the fact that the clutch is no longer designed so large must be, as in motor vehicles, the one described above Do not use the invention. The coupling can therefore be spatially, functionally and weight-reduced become. The same applies the leading from the transmission Drive train, which according to the invention must transmit a lower maximum torque.

Weitere bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung der Ausführungsbeispiele an Hand von Figuren.Further preferred embodiments emerge from the dependent claims and the following description of the embodiments with reference to Characters.
