Description
Die Erfindung betrifft eine automatische Getriebeeinrichtung mit den Merkmalen gemäß dem Oberbegriff von Anspruch 1.The invention relates to an automatic transmission device with the features according to the preamble of claim 1.
Automatisierte Schaltgetriebe finden in zunehmendem Maße Eingang in Kraftfahrzeugen. Mit ihnen wird nicht nur der Fahrkomfort verbessert sondern, da häufiger in verbrauchsgünstigen langen Gängen gefahren wird, wird auch der Verbrauch vermindert. In der Druckschrift
Die japanische Offenlegungsschrift
Eine Eigenart solcher automatisierter Schaltgetriebe, insbesondere die Übersetzung stufenweise verändernder Getriebe, bei denen die Drehmomentübertragung zwischen dem Antriebsmotor und dem oder den Antriebsrädern des Fahrzeugs zum Schalten durch Öffnen einer Kupplung unterbrochen werden muß, liegt darin, daß die Drehmomentunterbrechung den Fahrer überrascht, so daß er die Schaltung als störend bzw. unkomfortabel empfindet, wenn er die Schaltung nicht selbst ausgelöst hat.A peculiarity of such automated transmission, in particular the translation of gradually changing gear in which the torque transmission between the drive motor and the drive wheels or the vehicle must be interrupted for switching by opening a clutch, is that the torque interruption surprised the driver, so that he the circuit feels annoying or uncomfortable if he has not triggered the circuit itself.
Der Erfindung liegt die Aufgabe zugrunde, Abhilfe für das vorgenannte Problem zu schaffen.The invention has for its object to provide a remedy for the aforementioned problem.
Es wird der Fahrer auf eine bevorstehende Schaltung von dem System aufmerksam gemacht, so daß er sich auf die Situation einstellen kann und entsprechend von der Schaltung nicht überrascht wird. Der Anspruch 1 ist auf eine automatische Getriebeeinrichtung zur Lösung der Erfindungsaufgabe gerichtet.The driver is alerted to an imminent shift by the system so that it can adapt to the situation and accordingly will not be surprised by the shift. The claim 1 is directed to an automatic transmission device for the solution of the invention task.

Die Kupplung
Wie eingangs erläutert, liegt eine Eigenart von Antriebssträngen, mit einer die Drehmomentübertragung zwischen Motor und Antriebsrädern bzw. die Zugkraft unterbrechenden Kupplung, darin, daß beim kurzzeitigen Öffnen der Kupplung und unter Last laufendem Motor die Fahrzeugbeschleunigung beispielsweise beim Hochschalten von dem zweiten in den dritten Gang kurzzeitig unterbrochen wird, was insbesondere für den Fahrer überraschend sein kann und ihm ein unkomfortables Gefühl vermittelt.As explained above, is a peculiarity of drive trains, with a torque transmission between the engine and the drive wheels or the traction interrupting clutch, is that when briefly opening the clutch and under load running engine, the vehicle acceleration, for example, when upshifting from the second to the third gear is briefly interrupted, which can be particularly surprising for the driver and gives him an uncomfortable feeling.
