Hierbei werden die Getriebe bzw. Übersetzungsstufen gleichzeitig oder einzeln oder einzeln nacheinander geschaltet.Accordingly, it is suggested based on of the driver's request to set the optimal overall transmission ratio, whereby to set the overall gear ratio meets certain criteria Need to become. Here, the gears or gear ratios at the same time or switched individually or one after the other.
Der Fahrerwunsch kann beispielsweise über Positionshebel oder entsprechende Switches (z.B. für Low-Range, High-Range, Winter, Sport, Sand...) oder über die Drosselklappeneinstellung und/oder das Motormoment des Antriebsmotors oder auch durch angeforderte Kraftstoffverbrauchs- und/oder Abgaskennwerte erkannt werden. Alternativ ist es beispielsweise auch möglich, den Fahrerwunsch über übliche Fahrertyp- bzw. Fahrzustandserkennungseinrichtungen des Getriebes zu erkennen.The driver's request can be made using position levers, for example or corresponding switches (e.g. for low-range, high-range, winter, sports, Sand ...) or over the throttle valve setting and / or the engine torque of the drive motor or also through requested fuel consumption and / or exhaust gas parameters be recognized. Alternatively, it is also possible, for example Driver request via usual driver type or to detect driving state detection devices of the transmission.
Erfindungsgemäß wird vorzugsweise eine Gesamtübersetzung eingestellt, welche den günstigsten Gesamtwirkungsgrad aufweist. Hierbei können im Rahmen einer vorteilhaften Variante des Verfahrens als relevante Kriterien die Reibungsverluste in Verbindung mit der Gesamtübersetzung und dem günstigsten Betriebsbereich des Verbrennungsmotors berücksichtigt werden.According to the invention, an overall translation is preferred set which is the cheapest Has overall efficiency. This can be advantageous Variant of the process as relevant criteria the friction losses in Connection with the overall translation and the cheapest Operating range of the internal combustion engine are taken into account.
Desweiteren ist vorgesehen, dass sämtliche Getriebe bzw. Übersetzungsstufen (d.h. sowohl das „normale" Automatgetriebe als auch das nach- oder vorgeschaltete Getriebe) selbstständig unter Last geschaltet werden können. Zudem weisen sämtliche Getriebe bzw. Übersetzungsstufen Eingangs- und Ausgangsdrehzahlsensoren auf.Furthermore, it is provided that all gears or translation levels (i.e. both the "normal" automatic transmission as well as the downstream or upstream transmission) Load can be switched.

Gemäß der Erfindung ist vorgesehen, anhand des Fahrerwunsches die jeweils optimale Gesamtübersetzung einzustellen, wobei zum Einstellen der Gesamtübersetzung bestimmte Kriterien erfüllt werden müssen. Hierbei werden die Getriebe bzw. Übersetzungsstufen gleichzeitig oder einzeln oder einzeln nacheinander geschaltet.According to the invention it is provided the optimal overall gear ratio based on the driver's request adjust, with certain criteria for setting the overall translation be fulfilled have to. Here, the gears or gear ratios at the same time or switched individually or one after the other.
Wenn nacheinander geschaltet wird, dann können gemäß der Erfindung die Schaltungen so ineinander verschachtelt werden, dass der Fahrer dies als eine Schaltung empfindet.When switching sequentially, then can according to the invention the circuits are nested so that the driver feels this as a circuit.
Das hier vorgestellte Verfahren ermöglicht auch spontanen Schaltungen oder auch Abbruchschaltungen, d.h. eine Rückgängigmachung der durchgeführten Schaltung.The method presented here also enables spontaneous circuits or also abort circuits, i.e. an undo the carried out Circuit.
Diese Schaltungen können in vorteilhafter Weise durch eine Drehzahlführung bzw. Drehzahlvorgabe des Antriebsmotors, oder einen Motoreingriff unterstützt werden. Hierbei kann die Momentenvorgabe positiv oder negativ sein, wobei auch momentenneutrale Schaltungen realisierbar sind.These circuits can be in advantageously by speed control or speed specification of the drive motor, or a motor intervention are supported. The torque specification can be positive or negative, whereby Even torque-neutral circuits can be implemented.
Gemäß der Erfindung können Übersetzungen, die ähnliche bzw. leicht unterschiedliche Werte haben, weggelassen werden, oder zum Zwecke der Wirkungsgradoptimierung gezielt genutzt werden; es können auch Zwischengänge geschaltet werden. Im Gelände kann erfindungsgemäß während der Fahrt, ohne oder mit sehr kurzer Zugkraftunterbrechung geschaltet werden.According to the invention, translations, the similar or have slightly different values, are omitted, or be used for the purpose of efficiency optimization; it can too between courses be switched. In terrain can according to the invention during the Travel switched without or with a very short interruption in tractive power become.
Wenn vom Fahrer eine maximale Beschleunigung vom Stand aus gewünscht wird, dann wird abhängig von der momentanen Fahrzeugausladung, vom momentan zur Verfügung stehenden Motormoment, von der Motorleistung und vom Fahrwiderstand die ideale Übersetzungsreihe gewählt.If the driver has maximum acceleration desired from the stand becomes dependent from the current vehicle radius, from the currently available Engine torque, engine power and driving resistance are the ideal gear ratio series selected.
Das Verfahren ist sowohl für die Vorwärtsgänge als auch für die Rückwärtsgänge des Antriebsstrangs anwendbar.The procedure is for both the forward gears as well also for the reverse gears of the Powertrain applicable.
Gemäß einer vorteilhaften Variante der Erfindung ist vorgesehen, dass wenn zwei Getriebe bzw. Übersetzungsstufen gleichzeitig geschaltet werden und ein Getriebe, beispielsweise aufgrund eines Fehlers oder einer unzulässigen Drehzahl ("Überdrehzahl") nicht in der Lage ist, die gewünschte Übersetzung einzustellen, bzw. die Schaltung wird aus irgendeinem Grund rückgängig gemacht, so wird auch das andere Getriebe die Schaltung rückgängig machen. Es ist natürlich auch denkbar, dass in so einem Fall, wenn möglich, eine möglichst naheliegende Ersatzgesamtübersetzung gewählt wird.According to an advantageous variant The invention provides that if two gears or gear ratios be switched simultaneously and a transmission, for example due to an error or an impermissible speed ("overspeed") is unable to get the desired ratio discontinue, or the circuit will be undone for some reason, so the other gearbox will also reverse the shift. Of course it is conceivable that in such a case, if possible, one if possible obvious replacement overall translation chosen becomes.
