Abstract
Description
Die Erfindung betrifft ein Hybridfahrzeug mit einer Brennkraftmaschine und einer ersten elektrischen Maschine, welche mit der Kurbelwelle der Brennkraftmaschine antriebsverbunden ist, wobei die Brennkraftmaschine zumindest einen in einem Einlassstrang angeordneten Verdichter aufweist. Weiters betrifft die Erfindung ein Verfahren zum Betreiben eines Hybridfahrzeuges, welches eine Brennkraftmaschine und zumindest eine erste elektrische Maschine aufweist, welche in zumindest einem Betriebsbereich durch die Brennkraftmaschine angetrieben wird, wobei die Ansaugluft über zumindest einen im Einlassstrang angeordneten Verdichter verdichtet wird. The invention relates to a hybrid vehicle having an internal combustion engine and a first electric machine, which is drive-connected to the crankshaft of the internal combustion engine, wherein the internal combustion engine has at least one compressor arranged in an inlet line. Furthermore, the invention relates to a method for operating a hybrid vehicle having an internal combustion engine and at least one first electric machine, which is driven in at least one operating range by the internal combustion engine, wherein the intake air is compressed via at least one compressor arranged in the inlet line.
Aus den Veröffentlichungen
Aufgabe der Erfindung ist es, den Wirkungsgrad des Antriebstranges eines Hybridfahrzeuges zu verbessern. The object of the invention is to improve the efficiency of the drive train of a hybrid vehicle.
Erfindungsgemäß wird dies dadurch erreicht, dass der Verdichter über eine zweite elektrische Maschine antreibbar ist, wobei die zweite elektrische Maschine in zumindest einem Betriebsbereich der Brennkraftmaschine generatorisch betreibbar ist. Vorzugsweise ist vorgesehen, dass die zweite elektrische Maschine im Teillastbereich generatorisch betreibbar ist. According to the invention this is achieved in that the compressor is drivable via a second electric machine, wherein the second electric machine is operable as a generator in at least one operating range of the internal combustion engine. It is preferably provided that the second electric machine can be operated as a generator in the partial load range.
An der Teillast wird durch Drosselung der Ansaugluft Strom erzeugt. Um die Verluste möglichst klein zu halten, ist es vorteilhaft, wenn die erste elektrische Maschine momentenfrei im Leerlauf betrieben wird, sobald die zweite elektrische Maschine generatorisch betrieben wird. At the partial load, current is generated by throttling the intake air. In order to keep the losses as small as possible, it is advantageous if the first electric machine is operated at idle torque-free, as soon as the second electric machine is operated as a generator.
Die Schaufeln des Verdichters arbeiten als Turbine und drosseln die Ansaugluft. Die an der Teillast anfallenden Drosselverluste, welche bei herkömmlichen Brennkraftmaschinen an der Drosselklappe auftreten, werden bei Betrieb der zweiten elektrischen Maschine als Generator sinnvoll zur Erzeugung von elektrischer Energie genutzt. Der normale Generator der Brennkraftmaschine – die erste elektrische Maschine – kann dabei ohne Belastung umlaufen und somit die Reibung reduzieren. Das Verdichterlaufrad arbeitet im Turbinenbetrieb am Effektivsten, wenn die Strömungsrichtung umgekehrt wird. Um dies zu erreichen, ist es vorteilhaft, wenn der Verdichter im Umkehrbetrieb betreibbar ist, sobald die zweite elektrische Maschine generatorisch betrieben wird, wobei vorzugsweise eine erste Umkehrleitung stromaufwärts des Verdichters vom Einlassstrang abzweigt und stromabwärts des Verdichters in den Einlassstrang einmündet. Eine zweite Umkehrleitung kann dabei stromaufwärts des Verdichters zwischen der ersten Umkehrleitung und dem Verdichter vom Einlassstrang abzweigen und stromabwärts des Verdichters und der Einmündung der ersten Umkehrleitung in den Einlassstrang einmündet, wobei zwischen den Abzweigungen und den Einmündungen der ersten und zweiten Umkehrleitung jeweils Absperreinrichtungen angeordnet sein können. The blades of the compressor work as a turbine and throttle the intake air. The resulting at the partial load throttle losses, which occur in conventional internal combustion engines at the throttle, are used in operation of the second electric machine as a generator useful for generating electrical energy. The normal generator of the internal combustion engine - the first electric machine - can rotate without load and thus reduce friction. The compressor impeller works most effectively in turbine operation when the direction of flow is reversed. To achieve this, it is advantageous if the compressor is operable in reverse mode as soon as the second electric machine is operated as a generator, wherein preferably a first return line upstream of the compressor branches off from the intake branch and opens into the intake branch downstream of the compressor. In this case, a second reversing line can branch off from the inlet line upstream of the compressor between the first reversing line and the compressor and opens into the inlet line downstream of the compressor and the junction of the first reversing line, whereby shut-off devices can be arranged between the branches and the junctions of the first and second reversing line ,
