Abstract

Im Rahmen des Verfahrens zum Reduzieren des Kraftstoffverbrauchs durch Fahren im Leerlauf bei automatisierten Getrieben in Mehrgruppenbauweise wird die Neutralstellung am Abtrieb des Getriebes geschaltet.As part of the process for reducing fuel consumption by driving at idle in automated transmissions in multi-group design, the neutral position is switched at the output of the transmission.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Reduzieren des Kraftstoffverbrauchs durch Fahren im Leerlauf bei automatisierten Getrieben in Mehrgruppenbauweise, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a method for reducing the Fuel consumption by driving at idle with automated Driven in multi-group construction, according to the preamble of the claim 1.

Getriebe in Mehrgruppenbauweise umfassen in der Regel eine Vorgelegegruppe, ein Hauptgetriebe und ein Gruppengetriebe, das in der Regel aus einer Bereichsgruppe besteht.transmission in multi-group construction usually include a subgroup, a main transmission and a group transmission, which usually consists of a Range group.

Aus dem Stand der Technik ist bekannt, den Kraftstoffverbrauch durch Fahren in Neutralstellung unter bestimmten Betriebsbedingungen (Segeln, Eco-Roll) zu reduzieren.Out the prior art is known, the fuel consumption by Driving in neutral position under certain operating conditions (sailing, eco-roll) to reduce.

Hierbei ist vorgeschlagen worden, dies durch Öffnen der Kupplung, durch Schalten der Splitgruppe in Neutral oder durch Schalten des Hauptgetriebes in Neutral zu realisieren.in this connection has been proposed to do so by opening the clutch, by shifting the split group in neutral or by switching the main gearbox to realize in neutral.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Reduzieren des Kraftstoffverbrauchs durch Fahren im Leerlauf bei automatisierten Getrieben in Mehrgruppenbauweise anzugeben, durch dessen Durchführung der Kraftstoffverbrauch im Vergleich zum Stand der Technik weiter reduziert wird.Of the The present invention is based on the object, a method to reduce fuel consumption by driving at idle in multi-group automated transmissions, indicate through its implementation the fuel consumption compared to the prior art further reduced becomes.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.

Demnach wird bei einem automatisierten Getriebe in Mehrgruppenbauweise vorgeschlagen, zum Reduzieren des Kraftstoffverbrauchs durch Fahren im Leerlauf, die Neutralstellung am Abtrieb des Getriebes zu schalten. Da üblicherweise die Bereichsgruppe in Kraftflussrichtung dem Abtrieb vorgeschaltet ist, wird erfindungsgemäß die Bereichsgruppe in Neutral geschaltet.Therefore is proposed in an automated transmission in multi-group construction, for Reducing fuel consumption by driving at idle, the Neutral position at the output of the transmission to switch. As usual the range group in the power flow direction upstream of the output is, according to the invention, the range group switched to neutral.

Gemäß der Erfindung kann dies durch ein Schaltelement, vorzugsweise einen 3-Stellungszylinder oder einen 2-Stellungszylinder mit entsprechend von der Getriebe-Elektronik/-Sensorik angesteuerter Neutralstellung erfolgen.According to the invention This can be done by a switching element, preferably a 3-position cylinder or a 2-position cylinder with corresponding from the transmission electronics / sensors controlled neutral position.

Durch die erfindungsgemäße Konzeption erfolgt die Neutralstellung am Abtrieb des Getriebes, was in einer Minimierung der Getriebeverluste und somit der Bremsverluste beim Rollen des Fahrzeugs resultiert.By the conception according to the invention takes place the neutral position at the output of the transmission, which in one Minimizing the transmission losses and thus the braking losses during Rolling of the vehicle results.

Die Erfindung wird anhand der beigefügten Figur, welche ein Getriebeschema eines automatisierten Getriebes in Mehrgruppenbauweise darstellt, beispielhaft näher erläutert.The Invention will be described with reference to the attached figure, which a transmission scheme of an automated transmission in multi-group construction represents, exemplary closer explained.

In der Figur ist die Antriebswelle mit 1, die Vorgelegewelle mit 2 und die Abtriebswelle des Getriebes mit 3 bezeichnet. Durch einen 3-Stellungszylinder 4 mit entsprechender Neutralstellung bzw. ein weiteres geeignetes Schaltelement kann gemäß der Erfindung neben der schnellen und der langsamen Gruppe auch in Neutral geschaltet werden, wie in der Figur veranschaulicht.In the figure, the drive shaft with 1 , the countershaft with 2 and the output shaft of the transmission with 3 designated. Through a 3-position cylinder 4 with appropriate neutral position or another suitable switching element can be switched in accordance with the invention in addition to the fast and the slow group in neutral, as illustrated in the figure.
