Abstract
Description
Die Erfindung betrifft eine Getriebesteuerungseinrichtung nach dem Oberbegriff des Patentanspruchs 1 bzw. 5. Des Weiteren betrifft die Erfindung Verfahren zum Betreiben einer Getriebesteuerungseinrichtung. The invention relates to a transmission control device according to the preamble of
Die Hauptkomponenten eines Antriebsstrangs eines Kraftfahrzeugs sind ein Antriebsaggregat und ein Getriebe. Das Getriebe wandelt Drehzahlen und Drehmomente und setzt so ein Zugkraftangebot des Antriebsaggregats um. Das Getriebe stellt das Zugkraftangebot des Antriebsaggregats an einem Abtrieb des Antriebsstranges des Kraftfahrzeugs bereit. The main components of a drive train of a motor vehicle are a drive unit and a transmission. The gearbox converts speeds and torques and thus converts a traction power supply of the drive unit. The transmission provides the tractive power of the drive unit at an output of the drive train of the motor vehicle ready.
Der Betrieb des Antriebsaggregats wird von einer Motorsteuerungseinrichtung gesteuert und/oder geregelt. Der Betrieb des Getriebes wird von einer Getriebesteuerungseinrichtung gesteuert und/oder geregelt. Die Motorsteuerungseinrichtung tauscht mit dem Antriebsaggregat und die Getriebesteuerungseinrichtung tauscht mit dem Getriebe Daten aus. Weiterhin tauschen die Motorsteuerungseinrichtung und die Getriebesteuerungseinrichtung untereinander Daten sowie gegebenenfalls mit weiteren Steuerungseinrichtungen Daten aus. The operation of the drive unit is controlled and / or regulated by a motor control device. The operation of the transmission is controlled and / or regulated by a transmission control device. The engine control unit exchanges with the drive unit and the transmission control unit exchanges data with the transmission. Furthermore, the engine control device and the transmission control device exchange data with one another and optionally with further control devices.
Aus der Praxis ist es bereits bekannt, dass eine Getriebesteuerungseinrichtung auf Grundlage von Eingangsdaten Ausgangsdaten generiert, so zum Beispiel Stellsignale für entlang eines Stellwegs verlagerbare Schaltelemente des Getriebes, wobei es sich bei diesen Schaltelementen um formschlüssige Schaltelemente und reibschlüssige Schaltelemente, vorzugsweise um Kuppelungen und/oder Bremsen und/oder Schiebemuffen, handelt, die zur Ausführung eines Gangwechsels geöffnet und/oder geschlossen werden müssen. Bei aus der Praxis bekannten Getriebesteuerungseinrichtungen wird die Position solcher Schaltelemente entlang ihres Stellwegs mithilfe von im Getriebe verbauten Wegsensoren gemessen. Fallen die Wegsensoren aus, so ist es bislang nicht möglich, die Position der Schaltelemente entlang ihres Stellwegs zu bestimmen. Vielmehr wird in diesem Fall davon ausgegangen, dass die Schaltelemente nach Ablauf einer bestimmten Zeit nach Ansteuerung derselben ihre gewünschte Position erreicht haben. It is already known from practice that a transmission control device generates output data on the basis of input data, for example actuating signals for shifting elements of the transmission which can be displaced along a travel, wherein these shifting elements are positive shift elements and frictional shift elements, preferably couplings and / or Brakes and / or sliding sleeves, is that must be opened and / or closed to perform a gear change. In known from practice transmission control devices, the position of such switching elements along their travel by means of built-in gearbox displacement sensors is measured. If the displacement sensors fail, it is not yet possible to determine the position of the switching elements along their travel. Rather, it is assumed in this case that the switching elements have reached their desired position after a certain time after driving the same.
Sollte die Getriebesteuerungseinrichtung als Eingangsdaten eine Drehzahl des Antriebsaggregats benötigen, so wird die Drehzahl des Antriebsaggregats der Getriebesteuerungseinrichtung als Eingangsdaten zur Verfügung gestellt. Bislang sind keine Lösungen bekannt, mithilfe derer die Getriebesteuerungseinrichtung selbst einfach und zuverlässig die Drehzahl des Antriebsaggregats ermitteln kann. If the transmission control device requires a rotational speed of the drive unit as input data, then the rotational speed of the drive unit of the transmission control device is made available as input data. So far, no solutions are known by means of which the transmission control device itself can easily and reliably determine the speed of the drive unit.
Aus der
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine neuartige Getriebesteuerungseinrichtung und Verfahren zum Betreiben derselben zu schaffen. On this basis, the present invention based on the object to provide a novel transmission control device and method for operating the same.
Diese Aufgabe wird nach einem ersten Aspekt der Erfindung durch eine Getriebesteuerungseinrichtung gemäß Patentanspruch 1 gelöst. This object is achieved according to a first aspect of the invention by a transmission control device according to
Hiernach empfängt die Getriebesteuerungseinrichtung von dem Getriebe als Eingangsdaten ein Messsignal eines getriebeinternen Beschleunigungssensors, wobei die Getriebesteuerungseinrichtung aus dem Messsignal des getriebeinternen Beschleunigungssensors die Position mindestens eines Schaltelements des Getriebes ermittelt. After that, the transmission control device receives from the transmission as input data a measurement signal of a transmission-internal acceleration sensor, wherein the transmission control device determines the position of at least one shift element of the transmission from the measurement signal of the internal transmission acceleration sensor.
Nach dem ersten Aspekt der Erfindung ermittelt die Getriebesteuerungseinrichtung die Position mindestens eines Schaltelements des Getriebes auf Grundlage des von dem getriebeinternen Beschleunigungssensor bereitgestellten Messsignals. Hiermit ist es dann möglich, auch bei Ausfall von Wegsensoren des Getriebes die Position von Schaltelementen des Getriebes zu ermitteln. According to the first aspect of the invention, the transmission control device determines the position of at least one shifting element of the transmission on the basis of the measurement signal provided by the transmission-internal acceleration sensor. This makes it possible to determine the position of switching elements of the transmission even in case of failure of displacement sensors of the transmission.
Vorzugsweise ermittelt die Getriebesteuerungseinrichtung aus dem Messsignal des getriebeinternen Beschleunigungssensors, ob das jeweilige Schaltelement des Getriebes entlang seines Stellwegs eine Endposition erreicht hat, insbesondere derart, dass ermittelt wird, ob das jeweilige Schaltelement entlang des jeweiligen Stellwegs gegen einen der jeweiligen Endposition zugeordneten Anschlag gedrückt ist, wobei die Getriebesteuerungseinrichtung aus dem Messsignal des getriebeinternen Beschleunigungssensors einen bei Auftreffen des jeweiligen Schaltelements auf den jeweiligen Anschlag im Getriebe entstehenden Körperschall ermittelt. Diese Ermittlung der Endposition von Schaltelementen, die in der jeweiligen Endposition gegen einen Anschlag im Getriebe gedrückt sind, ist besonders einfach und zuverlässig möglich. Preferably, the transmission control device determines from the measurement signal of the internal transmission acceleration sensor, whether the respective shift element of the transmission has reached an end position along its travel, in particular such that it is determined whether the respective shift element along the respective travel is pressed against one of the respective end position associated stop, wherein the transmission control device determines, from the measurement signal of the internal transmission acceleration sensor, a structure-borne noise arising when the respective switching element strikes the respective stop in the transmission. This determination of the end position of switching elements, which are pressed in the respective end position against a stop in the transmission, is particularly simple and reliable.
Diese Aufgabe wird nach einem zweiten Aspekt der Erfindung durch eine Getriebesteuerungseinrichtung gemäß Patentanspruch 5 gelöst. This object is achieved according to a second aspect of the invention by a transmission control device according to claim 5.
Hiernach empfängt die Getriebesteuerungseinrichtung von dem Getriebe als Eingangsdaten ein Messsignal eines getriebeinternen Beschleunigungssensors, wobei die Getriebesteuerungseinrichtung aus dem Messsignal des getriebeinternen Beschleunigungssensors eine Drehzahl eines mit dem Getriebe gekoppelten Antriebsaggregats ermittelt. After that, the transmission control device receives from the transmission as input data Measuring signal of a transmission-internal acceleration sensor, wherein the transmission control device determines from the measurement signal of the internal-transmission acceleration sensor, a rotational speed of a drive unit coupled to the transmission.
Nach dem zweiten Aspekt der Erfindung, der entweder alleine oder in Kombination mit dem ersten Aspekt der Erfindung in einer Getriebesteuerungseinrichtung genutzt werden kann, wird die Drehzahl des Antriebsaggregats aus dem Messsignal des getriebeinternen Beschleunigungssensors ermittelt. Hiermit kann bei einer gestörten Kommunikation zwischen der Motorsteuerungseinrichtung und der Getriebesteuerungseinrichtung oder bei Ausfall eines Drehzahlsensors die Drehzahl des Antriebsaggregats von der Getriebesteuerungseinrichtung autark ermittelt werden. According to the second aspect of the invention, which can be used either alone or in combination with the first aspect of the invention in a transmission control device, the rotational speed of the drive assembly is determined from the measurement signal of the internal transmission acceleration sensor. This can be determined autonomously by the transmission control device in a disturbed communication between the engine control unit and the transmission control device or in case of failure of a speed sensor, the speed of the drive unit.
Vorzugsweise ermittelt die Getriebesteuerungseinrichtung auf Grundlage einer Schwingungsanalyse der Messsignale des Beschleunigungssensors die Drehzahl des Antriebsaggregats. Eine solche Schwingungsanalyse der Messsignale des Beschleunigungssensors zur Ermittlung der Drehzahl des Antriebsaggregats ist besonders einfach und zuverlässig durchführbar. The transmission control device preferably determines the rotational speed of the drive assembly on the basis of a vibration analysis of the measurement signals of the acceleration sensor. Such a vibration analysis of the measurement signals of the acceleration sensor for determining the rotational speed of the drive unit is particularly simple and reliable feasible.
