Demnach kann durch das erfindungsgemäße Verfahren der Fahrkomfort für den Fahrer wesentlich erhöht werden. Ferner ergeben sich Vorteile hinsichtlich der Spontaneität- und der Fahrleistungsbereiche, da mit dem erfindungsgemäßen Verfahren ermöglicht wird, mit der Geländeübersetzung auch anzufahren und dann bei Erreichen einer höheren Fahrzeuggeschwindigkeit in die Straßenübersetzung zu wechseln. Accordingly, a method according to the invention Proposed a change in the translation level too while driving at any speed is possible. As a result, the switching of the intended Translation level or target translation level even without one Stopping the vehicle can be realized. For example can do this without any time delay when entering or leaving done from the site. Accordingly, through the inventive method of driving comfort for the driver be significantly increased. There are also advantages in terms of spontaneity and mileage, since it is possible with the method according to the invention with to drive off the terrain translation and then at Reaching a higher vehicle speed in the To change road translation.
Eine Weiterbildung der vorliegenden Erfindung kann vorsehen, dass bei Vorliegen eines Fahrerwunsches zum Umschalten in die Straßen- oder Geländeübersetzung die Drehzahl des Fahrzeuges überprüft und festgelegt wird, ob ein Wechsel der Übersetzungsstufe möglich ist. Wenn dieser Wechsel möglich ist, kann von dem Getriebe ein lastloser Zustand eingestellt werden. Der Fahrerwunsch kann beispielsweise als Signal über ein Bordnetzsystem oder dergleichen dem Getriebe übermittelt werden. A further development of the present invention can provide that if there is a driver request for Switch to road or terrain translation The speed of the vehicle is checked and it is determined whether a Changing the translation level is possible. If this Change is possible, the gearbox can be a no-load State can be set. The driver request can for example as a signal via an electrical system or the like are transmitted to the transmission.
Das Einstellen des lastlosen Zustandes kann gemäß einer weiteren Ausgestaltung der Erfindung durch eine geeignete Ansteuerung zumindest einer Kupplung des Getriebes ermöglicht werden, wodurch vorzugsweise ein Neutralzustand des Getriebes realisiert wird. Bei der Ansteuerung der Kupplung kann ein eingelegter Gang herausgenommen und eine Gangnachführung durchgeführt werden. Nach einer entsprechenden Rückmeldung über den erfolgten Wechsel in die Straßen- oder Geländeübersetzung kann dieser entsprechende Gang eingelegt werden, d. h., es kann in den Fahrzustand bzw. in die Fahrposition zurückgekehrt werden. The setting of the no-load condition can be done according to a further embodiment of the invention by a suitable control of at least one clutch of the transmission are made possible, whereby preferably a neutral state of the transmission is realized. When controlling the A clutch can be removed from an engaged gear and one Gear tracking can be carried out. After a appropriate feedback about the change to the This corresponding gear can be used for road or terrain translation be inserted, d. that is, it can be in the driving state or in the driving position can be returned.
Im Rahmen einer Ausgestaltung der Erfindung kann bei der Gangnachführung vorgesehen sein, dass der einzulegende Gang entsprechend der Schaltkennlinie der neuen Übersetzungsstufe bzw. der Zielübersetzungsstufe ausgewählt wird. Within the scope of an embodiment of the invention the gear tracking that the to be inserted Gear according to the shift characteristic of the new one Translation level or the target translation level is selected.
In einer weiteren vorteilhaften Ausgestaltung der vorliegenden Erfindung kann zum Herstellen eines lastlosen Zustandes beim Einstellen der Straßen- oder der Geländeübersetzung eine entsprechende Momenten- und/oder Drehzahlnachführung des Motors vorgesehen sein. Es ist möglich, dass bei der Momentennachführung eine geeignete Momentenregelung zum Herstellung des lastlosen Zustandes vorgesehen ist, wobei nach dem Schalten des Getriebes zusätzlich die Drehzahlnachführung realisiert werden kann, um auf diese Weise ebenfalls das Schalten der Zielübersetzungsstufe zu ermöglichen. In a further advantageous embodiment of the present invention can be used to manufacture a no-load Condition when setting the road or the Terrain translation a corresponding moment and / or Speed tracking of the engine can be provided. It is possible, that a suitable one for the moment tracking Torque control is provided to establish the no-load condition is, after switching the transmission additionally Speed tracking can be realized on this Also assign the switching of the target translation stage enable.
Eine Weiterbildung der vorliegenden Erfindung kann vorsehen, dass für die jeweiligen Übersetzungsstufen entsprechende Parameter für die Fahrsteuerung bzw. Fahrsoftware umgeschaltet werden, um damit eine genaue Anpassung der Fahrsoftware an die Eigenschaften der jeweiligen Übersetzungsstufe zu ermöglichen.

The required parameters selected together or individually become.
Ferner ist bei dem erfindungsgemäßen Verfahren vorgesehen, dass Prüfungen durchgeführt werden, in wie weit ein entsprechender Wechsel der Übersetzungsstufen, insbesondere für den Wechsel in die Geländeübersetzung, möglich ist, um bei einer zu hohen Fahrzeuggeschwindigkeit eine Beschädigung des Getriebes oder des Antriebsmotors, z. B. durch Überdrehzahlen, zu vermeiden bzw. die Belastung des Antriebsstrangs infolge des Übersetzungsstufenwechsels zu vermindern. Selbstverständlich können durch die Prüfung der Zulässigkeit eines Übersetzungsstufenwechsels auch fahrdynamisch sicherkeitskritische Zustände sicher vermieden werden. Wird während eines Wechsels der Übersetzungsstufen eine Unzulässigkeit festgestellt, so wird dieser Wechsel abgebrochen und wieder der ursprüngliche Gang bzw. der ursprüngliche Schaltungszustand vor dem gewünschten Wechsel eingestellt. Furthermore, the method according to the invention provided that exams are carried out in how far appropriate change of translation levels, in particular for the change in the terrain translation, is possible to if the vehicle speed is too high a Damage to the gearbox or the drive motor, e.g. B. by Overspeed, to avoid or the load on the Drivetrain due to the gear ratio change Reduce. Of course, by examining the Permissibility of a change of translation level too Driving dynamics safety-critical conditions safely avoided become. Will be during a change of translation levels If this is found to be inadmissible, this change will be made canceled and the original gear or the Original circuit status before the desired change set.
