Abstract
Vorrichtung zum Steuern eines automatisch schaltenden Getriebes für ein Kraftfahrzeug mit einer ersten Wähleinrichtung, mit der zumindest die in einem Automatikmodus einstellbaren Fahrstufen festlegbar sind, mit einer zweiten Wähleinrichtung, durch die in einem Manuellmodus die Gänge des Getriebes stufenweise manuell hoch- oder rückschaltbar sind, und mit einem elektronischen Steuergerät, das abhängig von den Signalen der Wahleinrichtungen und weiteren Eingangssignalen die Stellglieder des Getriebes ansteuert, wobei das Steuergerät derart ausgestaltet ist, dass bei Betätigung der zweiten Wähleinrichtung ausgehend vom Automatikmodus unmittelbar ein angeforderter Gangwechsel abweichend vom Automatikmodus durchgeführt wird, dadurch gekennzeichnet, dass das Steuergerät (3) weiterhin derart ausgestaltet ist, – dass nach Betätigung der zweiten Wähleinrichtung (2), die ausgehend vom Automatikmodus zu einem unmittelbaren Gangwechsel geführt hat, ein Prüfvorgang gestartet wird, ob der aktuell eingelegte Gang dem Anfahrgang im Automatikmodus entspricht, wenn der aktuell einzulegende Gang gemäß dem Automatikmodus der Anfahrgang wäre, und – dass die Steuerung der weiteren Gangwechsel wieder entsprechend dem Automatikmodus durchgeführt wird, wenn der aktuell eingelegte Gang höher als der Anfahrgang entsprechend dem Automatikmodus ist.Device for controlling an automatically shifting transmission for a motor vehicle with a first selection device, with which at least the adjustable in an automatic mode travel levels can be fixed, with a second selection device, through which in a manual mode, the gears of the transmission are gradually manually up or down, and with an electronic control unit that controls the actuators of the transmission depending on the signals of the selectors and other input signals, wherein the control unit is configured such that upon actuation of the second selection device from the automatic mode immediately a requested gear change is performed deviating from the automatic mode, characterized in that the control unit (3) is furthermore configured in such a way that - after actuation of the second selection device (2) which has led to an immediate change of gear starting from the automatic mode - a checking procedure is started whether the currently engaged gear corresponds to the starting gear in automatic mode, if the current gear to be engaged according to the automatic mode would be the starting gear, and - that the control of the further gear changes is again performed according to the automatic mode, if the currently engaged gear is higher than the starting gear corresponding to the Automatic mode is.
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Steuern eines automatisch schaltenden Getriebes nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for controlling an automatically shifting transmission according to the preamble of

Es ist Aufgabe der Erfindung, eine Vorrichtung zum Steuern eines automatisch schaltenden Getriebes im Hinblick auf die Fahrdynamik zu verbessern.It is an object of the invention to improve a device for controlling an automatically shifting transmission in terms of driving dynamics.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Eine vorteilhafte Weiterbildung ist der Gegenstand des abhängigen Patentanspruchs.This object is achieved by the features of
Mit der erfindungsgemäßen Vorrichtung wird insbesondere durch entsprechende Programmierung des elektronischen Steuergeräts nach Betätigung der zweiten Wähleinrichtung, die ausgehend vom Automatikmodus zu einem unmittelbaren Gangwechsel geführt hat, ein Prüfvorgang gestartet, ob der aktuell eingelegte Gang dem Anfahrgang im Automatikmodus entspricht, wenn gemäß dem Automatikmodus, insbesondere abhängig von der aktuellen Fahrzeuggeschwindigkeit und/oder dem aktuellen Fahrerwunsch, der momentan einzulegende Gang der Anfahrgang wäre. Die Steuerung der weiteren Gangwechsel wird wieder entsprechend dem Automatikmodus durchgeführt, wenn der aktuell eingelegte Gang höher als der Anfahrgang entsprechend dem Automatikmodus ist.With the device according to the invention, in particular by appropriate programming of the electronic control device after actuation of the second selection device, which has led from the automatic mode to an immediate gear change, a test process is started, if the currently engaged gear corresponds to the starting gear in automatic mode, if according to the automatic mode, in particular Depending on the current vehicle speed and / or the current driver's request, the currently engaged gear would be the starting gear. The control of the further gear changes is again performed according to the automatic mode, if the currently engaged gear is higher than the starting gear corresponding to the automatic mode.
Vorzugsweise wird die Steuerung der weiteren Gangwechsel unabhängig vom aktuell eingelegten Gang wieder entsprechend dem Automatikmodus durchgeführt, nachdem die Kupplung zwischen dem Antrieb und dem Getriebe geöffnet (und anschließend wieder geschlossen) wurde. Diese Kupplung kann z. B. die einzige Kupplung bei automatisierten Getrieben, jede Kupplung eines Teilgetriebes bei Doppelkupplungsgetrieben, eine Kupplung im Automatikgetriebe oder die Kupplung eines Drehmomentwandlers bei Automatikgetrieben sein.Preferably, the control of the further gear changes is performed independently of the currently engaged gear again according to the automatic mode after the clutch between the drive and the transmission has been opened (and then closed again). This coupling can, for. As the only clutch in automated transmissions, each clutch of a partial transmission in dual-clutch transmissions, a clutch in the automatic transmission or the clutch of a torque converter in automatic transmissions.
Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert. Dazu ist in der Zeichnung ein Überblick über eine für die Erfindung vorteilhafte Gesamtanordnung dargestellt.The invention will be explained in more detail with reference to an embodiment. For this purpose, an overview of an advantageous for the invention overall arrangement is shown in the drawing.
