Derartige Hybridfahrzeuge für den Straßenverkehr sind als kommerzielle Produkte im Handel. Die Elektromaschine dient dazu, beim Abbremsen des Fahrzeuges Energie zurückzugewinnen, die in einem Akkumulator gespeichert wird. Ferner hat die Elektromaschine die Aufgabe, das Fahrzeug zu bewegen, wenn nur wenig Antriebsleistung benötigt wird. Das Umschalten des Antriebes von der Brennkraftmaschine auf die Elektromaschine erfolgt durch eine Steuereinheit, die in Abhängigkeit von gemessenen Zustandsgrößen der Brennkraftmaschine und des Akkumulators und den jeweils gegebenen Anforderungen an das Fahrverhalten des Fahrzeuges arbeitet.such Hybrid vehicles for the traffic are commercially available as commercial products. The electric machine is used to recover energy when braking the vehicle, which in one Accumulator is stored. Furthermore, the electric machine has the Task to move the vehicle when driving power is low is needed. The switching of the drive from the internal combustion engine to the Electric machine is done by a control unit, depending on of measured state variables of Internal combustion engine and the accumulator and each given Requirements for the handling of the vehicle works.
Unter Elektromaschinen werden somit in den Ansprüchen und der vorliegenden Beschreibung elektrische Maschinen verstanden, die als Motor und Generator arbeiten können.Under Electric machines are thus in the claims and the present description electrical Understood machines that can work as a motor and generator.
Bei diesen bekannten Hybridfahrzeugen hat der Fahrer keine Einflussmöglichkeit auf Details des Arbeitens der Steuerschaltung.at This known hybrid vehicles, the driver has no influence on details of working the control circuit.
Ein derartiges Hybridfahrzeug ohne Eingriffsmöglichkeiten für den Fahrer ist gut geeignet, um im Alltagsverkehr den Kraftstoffverbrauch zu minimieren.One Such hybrid vehicle without intervention for the driver is well suited to fuel consumption in everyday traffic too minimize.
Es gibt jedoch auch andere Einsatzbedingungen für Fahrzeuge, bei denen man von der Idee eines Hybridantriebes gut Gebrauch machen könnte. Hierzu gehören Rennfahrzeuge, und zwar sowohl seriennahe Touren-Rennfahrzeuge als auch vollständig separat konzipierte Formel 1-Rennfahrzeuge oder dergleichen.It However, there are other conditions of use for vehicles in which one could make good use of the idea of a hybrid drive. For this belong Racing vehicles, both near-standard touring racing vehicles as also completely separate designed Formula 1 racing cars or the like.

Dies hat den weiteren Vorteil, dass nach Beendigung der gefährlichen Schlupfsituation die vorherigen Möglichkeiten zum Beschleunigen des Fahrzeuges sofort wieder unverändert zur Verfügung stehen. Beim klassischen Vorgehen steht dem die Trägheit der Lambda-Regelung entgegen.This has the further advantage that after completion of the dangerous Slip situation the previous possibilities to accelerate of the vehicle immediately available unchanged. The classic approach is counteracted by the inertia of the lambda control.
Wird

Elektromaschinen
Dass beim hier beschriebenen Fahrzeug kritischen Schlupfsituationen zunächst über die Elektromaschinen und nur in Extremfällen über die klassischen Instrumente begegnet wird hat auch den Vorteil, dass das Fahrzeug sicherer läuft. Die klassischen Instrumente ändern die von den Antriebswellen zu Übertragenden Drehmomente sprunghaft. Da die Antriebswellen unter den hohen Drehmomenten nicht unerheblich tordieren, können sprunghafte Änderungen des übertragenen Drehmomentes zu Schwinungen im Antriebsstrang führen, die sich auch auf die Räder übertragen und die Schlupfsitutation negativ beeinflussen. Außerdem können diese Schwingungen zu Materialbrüchen führen. Die Abhilfe über Elektromaschinen lässt sich feiner und stoßfreier gestalten.That in the vehicle described here critical slip situations first on the Electric machines and only in extreme cases on the classical instruments also has the advantage that the vehicle runs safely. The change classic instruments those to be transferred from the drive shafts Torques leaps and bounds. Since the drive shafts are not among the high torques irrelevant, can sudden changes of the transferred Torque cause drifting in the drivetrain, which also affect the Transfer wheels and negatively affect the hatching position. Besides, these vibrations can to material breaks to lead. The remedy over Electric machines leaves finer and bumpless shape.
