Bei der Energieumsetzung oder Energiewandlung soll diese in allen technischen Bereichen mit möglichst optimalem Wirkungsgrad erfolgen. Dies gilt auch für Kraftfahrzeuge, bei denen unter anderem auch kinetische Energie in elektrische Energie umgewandelt werden soll. Besonders bei Hybridfahrzeugen, also Fahrzeugen, die sowohl mit Hilfe einer Brennkraftmaschine als auch mit Hilfe einer elektrischen Maschine antreibbar sind, spielt die Verbesserung des Wirkungsgrades bei der Energieumsetzung bzw. Energiewandlung von kinetischer Energie in elektrische Energie und umgekehrt eine große Rolle.at the energy conversion or energy conversion should this in all technical Areas with as possible optimal efficiency. This also applies to motor vehicles, in which, among other things, kinetic energy is converted into electrical energy shall be. Especially in hybrid vehicles, ie vehicles that both with the help of an internal combustion engine as well as with the help of a Electric machine are drivable, the improvement of the plays Efficiency in the energy conversion or energy conversion of kinetic energy into electrical energy and vice versa a big role.

Die erfindungsgemäße Vorrichtung zur Energieumsetzung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass der Wirkungsgrad bei der Energieumsetzung, bzw. bei der Energiewandlung verbessert wird. Erzielt wird dieser Vorteil, indem bei einer Brennkraftmaschine im Abgastrakt eine Abgasturbine eingebaut wird, die mit einer elektrischen Maschine in Verbindung steht und insbesondere Bestandteil eines Turboladers ist. Bei geeigneter Ansteuerung arbeitet die elektrische Maschine als Generator, der von der Abgasturbine angetrieben wird und dabei kinetische Energie bzw. zusätzliche Energie aus dem Abgas zurückgewinnt und in elektrische Energie umwandelt, mit deren Hilfe Verbraucher gespeist bzw. betrieben werden können, oder die Fahrzeugbatterie aufgeladen werden kann. Durch die Ausnutzung der im Abgas vorhandenen Restenergie wird so der Gesamtwirkungsgrad des Fahrzeugs in besonders vorteilhafter Weise verbessert.The inventive device for energy conversion with the features of claim 1 has the advantage that the efficiency in the energy conversion, or in the energy conversion is improved. This advantage is achieved by an internal combustion engine in the exhaust tract an exhaust gas turbine is installed, which is connected to an electric Machine is connected and in particular part of a Turbocharger is. With suitable control, the electric works Machine as a generator, which is powered by the exhaust gas turbine and while kinetic energy or additional energy from the exhaust gas recovers and converted into electrical energy that helps consumers can be fed or operated, or the vehicle battery can be charged. By exploitation the residual energy present in the exhaust gas is thus the overall efficiency the vehicle improved in a particularly advantageous manner.
Weitere Vorteile der Erfindung werden durch die in den Unteransprüchen angegebenen Maßnahmen erzielt. Dabei ist besonders vorteilhaft, dass die Erfindung in einem Hybridfahrzeug eingesetzt wird und so den Wirkungsgrad des Hybridfahrzeuges mit Verbrennungsmotor bzw. Brennkraftmaschine und elektrischer Maschine verbessert.Further Advantages of the invention are given by the in the subclaims activities achieved. It is particularly advantageous that the invention in a hybrid vehicle is used and so the efficiency of the Hybrid vehicle with internal combustion engine or internal combustion engine and electric Machine improved.
Bei einem Fahrzeug, das ohnehin einen Turbolader bzw. eine Abgasturbine aufweist bzw. benötigt, kann in besonders vorteilhafter Weise anstelle des Generators eine elektrische Maschine eingesetzt werden, die sowohl in generatorischem Betrieb elektrische Energie erzeugen kann, als auch im motorischen Betrieb die Abgasturbine bzw. den Turbolader oder Verdichter antreiben kann. Damit ist es in vorteilhafter Weise möglich, im motorischen Betrieb bei Lastwechsel das so genannte Turboloch zu vermeiden und die Verdichtung mittels geeigneter Ansteuerung der elektrischen Maschine zu optimieren. Es ist dabei auch möglich, dass bei Lastsprüngen der Ladedruck schneller aufgebaut wird.at a vehicle, anyway a turbocharger or an exhaust gas turbine has or needs, can in a particularly advantageous manner instead of the generator a Electric machine can be used both in regenerative Operation can generate electrical energy, as well as in the motor Operation driving the exhaust turbine or the turbocharger or compressor can. This makes it possible in an advantageous manner, in engine operation to avoid the so-called turbo lag during load changes and the compression to optimize by means of suitable control of the electrical machine. It is also possible that at load jumps the boost pressure is built up faster.
Die Abgasturbine kann besonders vorteilhaft so ausgelegt werden, dass die maximal verfügbare Energie aus dem Abgas entnommen wird und außerdem das Ansprechverhalten des Turboladers verbessert wird. Durch eine vorteilhafte Regelung der elektrischen Maschine kann die Maximaldrehzahl des Turboladers begrenzt werden und damit die Abgasklappe ersetzt werden.The Exhaust gas turbine can be particularly advantageously designed so that the maximum available energy is removed from the exhaust and also the response of the turbocharger is improved. By an advantageous scheme The electrical machine can be the maximum speed of the turbocharger be limited and thus the exhaust flap to be replaced.
In einer besonders vorteilhaften Ausgestaltung ist eine Lösung möglich, bei der die Turbine des Turboladers mit einem Generator und der Verdichter des Turboladers mit einem Elektromotor verbunden sind, so dass einerseits über die Drehzahl des Verdichters der Ladedruck einstellbar ist und unabhängig von dieser Einstellung die Drehzahl der Abgasturbine einstellbar ist. Durch diese getrennte Einstellbarkeit der beiden Komponenten kann ein optimaler Arbeitspunkt des Gesamtsystems eingestellt werden. Bei getrennter Ausführung des Gesamtsystems kann die Flexibilität bei den Einbauraumanforderungen erhöht werden.In In a particularly advantageous embodiment, a solution is possible at the turbine of the turbocharger with a generator and the compressor of the Turbocharger are connected to an electric motor, so on the one hand over the Speed of the compressor the boost pressure is adjustable and independent of This setting the speed of the exhaust gas turbine is adjustable.

Bei einem Fahrzeug, das ohnehin einen Turbolader aufweist, kann dieser zur Rückgewinnung der im Abgas vorhandenen Restenergie eingesetzt werden. Dann ist es möglich, anstelle des Generators eine elektrische Maschine einzusetzen, die sowohl elektrische Energie erzeugen wie auch den Verdichter bzw. Turbolader antreiben kann. Damit ist es auch möglich, bei Lastwechseln das sogenannte Turboloch zu vermeiden. Dabei lässt sich die Abgasturbine dann auch so auslegen, dass die maximal verfügbare Energie aus dem Abgas entnommen wird, wobei der Kompromiss bezüglich des Ansprechverhaltens des Turboladers vermieden wird. Zusätzlich kann durch eine entsprechende Regelung der elektrischen Maschine die Maximaldrehzahl des Turboladers begrenzt werden. Damit kann die ansonsten bei Fahrzeugen mit Turbolader benötigte Abgasklappe ersetzt werden.at a vehicle that already has a turbocharger, this can to recover the used in the exhaust residual energy. Then it is possible, Instead of the generator to use an electric machine, the generate both electrical energy as well as the compressor or Turbocharger can drive. Thus it is also possible to load changes so-called turbo lag to avoid. In this case, the exhaust gas turbine can then Also, interpret that to the maximum available energy from the exhaust taking the compromise with respect to the response of the turbocharger is avoided. In addition, by an appropriate Regulation of the electric machine the maximum speed of the turbocharger be limited. This can otherwise be used on turbocharged vehicles needed Exhaust flap to be replaced.
