Description

Die Erfindung betrifft ein Antriebssystem, das die ge­ meinsame Regelung von Motor und Getriebeübersetzung optimieren soll.
In bezug auf Kraftstoffverbrauch und Schadstoffemission ist es notwendig, daß ein Motor im Bereich seiner optimalen Kennlinien in jedem Lastbereich betrieben wird. Hierzu ist es notwendig, daß das Getriebe sich stufenlos dem Motordrehmoment anpaßt.
Durch eine gemeinsame Regelung von Motor und Getriebe­ übersetzung ist eine optimale Leistungsausnutzung möglich. Der Erfindung liegt die Aufgabe zugrunde, daß der ge­ samte Antrieb so geregelt wird, daß in jedem Lastbereich der Motor im günstigsten Kennfeld betrieben wird. Diese Aufgabe wird erfindungsgemäß gelöst, daß ein Com­ puter sich die optimalsten Motorkennfelder in jedem Last­ und Drehzahlbereich selbst abtastet und die optimalste Relation von Motorregulierung und Getriebeübersetzung so steuert, daß der Kraftstoffverbrauch und die Schadstoff­ emission in bezug zur benötigten Leistung im günstigsten Bereich liegen.
Ein Ausführungsbeispiel der Erfindung ist in dem Block­ schaubild dargestellt.
Ein Planetengetriebe mit hydrostatischer Leistungsver­ zweigung, wobei der hydrostatische Zweig zur Kompensier­ ung der Schaltstufen des Planetengetriebes dient und da­ mit zum stufenlosen Getriebe wird, ist in diesem Zusammen­ hang sehr günstig, da die Regulierung der hydrostatischen Kompensierung auch vom Computer übernommen wird. Die Vorteile dieser Erfindung sind:
hoher Wirkungsgrad, geringer Kraftstoffverbrauch, weniger Schadstoffemission, stufenloser Antrieb und hoher Komfort. Die Anwendung dieser Erfindung am Turbinenmotor hat gute Zukunftschancen.
Die Programmabtastung erfolgt über Module.

Claims (2)

1. Optimierung der gesamten Antriebseinheit (Motor und Getriebe), dadurch gekennzeichnet, daß ein Computer sich die optimalsten Motorkennfelder selbst abtastet und da­ durch die Regelung in allen Fahrbereichen optimiert. Die Programmabtastung geschied über Module.
2. Die Regelung der hydrostatischen Leistungsver­ zweigung im Getriebe, dadurch gekennzeichnet, daß der Computer die hydro­ statische Leistungsverzweigung so regelt, daß damit eine Kompensierung des automatischen Getriebes statt­ findet und somit zum stufenlosen Getriebe wird.
