Description
Die Erfindung betrifft eine Einrichtung zur selbsttätigen Schaltung eines mehrgängigen Gangwechselgetriebes gem. des Oberbegriffes des Patentanspruches 1.The The invention relates to a device for automatic switching of a multi-speed gear change transmission gem. the preamble of claim 1.
Gattungsgemäße Einrichtungen

ist aus der
Vor diesem Hintergrund besteht die Aufgabe der Erfindung darin, gattungsgemäße Schalteinrichtungen so weiterzubilden, dass sie ein einem größeren Umfang der individuellen Fahrweise des jeweiligen Fahrzeugbedieners Rechnung tragen.In front In this context, the object of the invention is to provide generic switching devices so educate them that they are a larger scope of the individual Take into account the driving style of the respective vehicle operator.
Diese Aufgabe wird gelöst durch die Merkmale des Patentanspruches 1. Die Unteransprüche enthalten zweckmäßige Weiterbildungen der Erfindung.These Task is solved by the features of claim 1. The dependent claims appropriate training the invention.
Erfindungsgemäß werden also in der Rechnereinheit verschiedene Registergruppen vorgesehen, die in einer nachfolgend näher beschriebenen Weise die von den Sensoren an die Steuereinheit gemeldeten Signale in Befehle für eine jeweils einzustellende Gangbeeinflussung umwandelt. (Eine solche Beeinflussung kann die Aufrechterhaltung des gerade eingelegten Ganges oder ein Gangwechsel sein.) Zu diesem Zweck sind in einer ersten Registergruppe für bestimmte den Betriebszustandes Antriebmotors charakterisierende Größen Klassenzugehörigkeiten definiert. In vorteilhafter Weise wird dabei auf die gleichen Betriebzustandsgrößen zurückgegriffen wie bei dem Betrieb gattungsgemäßer Schalteinrichtungen. In einer zweiten Registergruppe sind erfindungsgemäß Regeln abgelegt, nach denen die Größen der ersten Registergruppe miteinander zur Erzeugung zweiter unscharfer Zwischenwerte verknüpft werden. Schließlich werden in einer dritten Registergruppe nach den Regeln der Fuzzy-Logik die in der zweiten Registergruppe gebildeten unscharfen Zwischenwerte in diskrete Ausgangswerte für eine einzulegende Gangstufe umgewandelt. Dabei wird vorteilhaft als das Fahrverhalten des Fahrzeugbedieners charakterisierende Größe die zeitliche Änderung des Fahrpedalwinkels in ein Register der ersten Registergruppe abgelegt. Zur Erhöhung der Verknüpfungstiefe ist in der zweiten Registergruppe ein viertes Register mit Regeln zur Verknüpfung der Klassen für die Fahrpedalwinkel mit den im dritten Register bestimmten zweiten unscharfen Zwischenwerten zur Stimmung eines dritten unscharfen Zwischenwertes abgelegt.According to the invention So provided in the computer unit different register groups, in a more detail below described manner reported by the sensors to the control unit Signals in commands for converts a respective setting course influence. (Such Influence may be the maintenance of the just inserted Ganges or a gear change.) For this purpose are in one first register group for certain the operating state of the drive motor characterizing Sizes Class Associations Are defined. Advantageously, the same operating state variables are used as in the operation of generic switching devices. In a second register group according to the invention rules filed according to which the sizes of the first register group with each other to produce second blurred Intermediate values linked become. After all In a third register group, according to the rules of fuzzy logic, the in the second register group formed fuzzy intermediate values in discrete output values for converted to a einzulegende gear. It will be advantageous as the driving behavior of the vehicle operator characterizing size the temporal change of the accelerator pedal angle stored in a register of the first register group. To increase the link depth is in the second register group a fourth register with rules for linking of the classes for the accelerator pedal angle with the second determined in the third register blurred intermediate values to the mood of a third blurred intermediate value stored.
Durch die erfindungsgemäße Ausbildung der Rechnereinheit wird somit für die Steuerung eines mehrgängigen Gangwechselgetriebes nicht mehr eine starre Kennfeldsteuerung verwendet oder eine Steuerung nur nach Fahrsituation, sondern auch nach Fahrverhalten des Fahrzeugbedieners eine bestimmte Betriebsweise festgelegt. Durch eine bis zu dritten unscharfen Zwischenwerten reichende, gewichtete Verknüpfung von Betriebszustandgrößen einerseits und Fahrverhaltensgrößen andererseits kann zum einen in vorteilhafter Weise auf bereits vorhandene Kennfelder zurückgegriffen und zum anderen den individuellen Fahrweisen verschiedener Fahrzeugbediener Rechnung getragen werden.By the training of the invention the computer unit is thus for the control of a multi-course Gear change gear no longer uses a rigid map control or a control only after driving situation, but also after driving behavior set the vehicle operator a specific mode of operation. By a weighted up to third blurred intermediate values shortcut of operating state variables on the one hand and driving behavior variables on the other hand on the one hand in an advantageous manner to already existing maps resorted and on the other hand, the individual driving styles of various vehicle operators Be taken into account.
Ein besonderer Vorteil der erfindungsgemäßen Lösung ist darin zu sehen, dass sie an bereits im Betrieb befindlichen Schalteinrichtung nachgerüstet werden kann und im Bereich des Getriebes selbst keinerlei apparative Änderungen notwendig werden.One particular advantage of the inventive solution is the fact that they are retrofitted to already in operation switching device can and in the field of the transmission itself no apparative changes become necessary.
