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.
