Description

Einrichtung zum Erfassen von Betriebszuständen in einem automatischen Schaltgetriebe  Device for detecting operating conditions in an automatic transmission
Die Erfindung betrifft eine Einrichtung zum Erfassen von Betriebszuständen in einem Schaltgetriebe, welche Positionssensoren zur Erfassung der jeweiligen Position von schaltbaren Getriebeelementen sowie Mittel zur Temperaturmessung im Getriebegehäuse aufweist. The invention relates to a device for detecting operating conditions in a manual transmission, which has position sensors for detecting the respective position of switchable transmission elements and means for measuring temperature in the transmission housing.
Für den sicheren Betrieb und die Steuerung der Schalt- und Wählabläufe in einem automatischen Schaltgetriebe ist es erforderlich, sowohl die Öltemperatur im Getriebegehäuse als auch die aktuelle Position der schaltbaren Getriebeelemente, wie etwa Schaltgabeln, zu erfassen, um eine elektronische Getriebesteuereinheit mit den entsprechenden Informationen zu versorgen. Herkömmliche Einrichtungen zum Erfassen dieser Betriebszustände verwenden eine Anzahl von den schaltbaren Getriebeelementen zugeordneten Positionssensoren sowie einen Temperatursensor, wobei diese Sensoren über jeweils gesonderte Sensorleitungen und einen zentralen Verbindungsstecker mit einer Getriebesteuereinheit signaltechnisch verbunden sind. For the safe operation and control of the shift and select operations in an automatic transmission, it is necessary to detect both the oil temperature in the transmission case and the current position of the shiftable transmission elements, such as shift forks, to provide an electronic transmission control unit with the appropriate information supply. Conventional devices for detecting these operating states use a number of the position sensors associated with the shiftable transmission elements and a temperature sensor, wherein these sensors are signal-technically connected via respective separate sensor lines and a central connecting plug to a transmission control unit.
Nachteilig dabei ist, dass man auf diese Weise keine ausreichend zuverlässige und genaue Information über die Temperaturverteilung im Getriebegehäuse erhält, da diese nur an einer nicht für das ganze Getriebe repräsentativen Stelle gemessen wird. Eine Installation mehrerer über das Getriebegehäuse verteilter Temperatursensoren mit den zugehörigen Kabeln ist aus Gründen des beschränkten Einbauraumes im Getriebegehäuse und im Hinblick auf eine zusätzliche Blockierung der Schnittstelle an der Getriebesteuereinheit schwierig; außerdem würden diese zusätzlich Kosten verursachen. The disadvantage here is that in this way no sufficiently reliable and accurate information about the temperature distribution in the gear housing is obtained, since this is measured only at a point not representative of the whole transmission. Installation of several distributed over the gear housing temperature sensors with the associated cables is difficult for reasons of limited installation space in the gear housing and in terms of additional blocking of the interface to the transmission control unit; moreover, they would incur additional costs.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Einrichtung der oben genannten Art vorzustellen, die bei geringen Kosten und ohne das Erfordernis zusätzlichen Einbauraumes neben der erwähnten Positions- messung auch eine zuverlässigere sowie genauere Erfassung der Temperatur im Getriebegehäuse ermöglicht. Against this background, the invention has for its object to provide a device of the type mentioned above, which at low cost and without the need for additional installation space in addition to the above-mentioned position measurement also allows a more reliable and more accurate detection of the temperature in the transmission housing.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Hauptanspruchs, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnehmbar sind. The solution of this problem arises from the features of the main claim, while advantageous embodiments and further developments of the invention are the dependent claims can be removed.
Der Erfindung liegt die Erkenntnis zugrunde, dass eine Temperaturmessung durch Nutzung der ohnehin im Getriebegehäuse angeordneten Positionssensoren und deren jeweiligen Sensorleitung im Wesentlichen ohne zusätzlichen Einbauraum möglich ist. The invention is based on the finding that a temperature measurement by using the already arranged in the transmission housing position sensors and their respective sensor line is essentially possible without additional installation space.
Demnach geht die Erfindung aus von einer Einrichtung zum Erfassen von Be- triebszuständen in einem Schaltgetriebe, welche Positionssensoren zur Erfassung der jeweiligen Position von schaltbaren Getriebeelementen sowie Mittel zur Temperaturmessung im Getriebegehäuse aufweist. Accordingly, the invention is based on a device for detecting operating conditions in a manual transmission, which has position sensors for detecting the respective position of shiftable transmission elements and means for measuring temperature in the transmission housing.
Zur Lösung der gestellten Aufgabe ist bei dieser Einrichtung vorgesehen, dass in oder an dem Sensorgehäuse von wenigstens einem Positionssensor ein Mittel zur Temperaturmessung baulich integriert ist. To achieve the object, it is provided with this device that a means for measuring the temperature is structurally integrated in or on the sensor housing of at least one position sensor.
Zur Bestimmung der Temperatur an unterschiedlichen Orten im Getriebegehäuse werden wenigstens zwei solcher kombinierter Positions- und Temperatursensoren eingebaut und genutzt. Man erhält auf diese Weise eine der Anzahl der vorgesehenen Positionssensoren sowie deren Verteilung über den Getrie- begehäuseinnenraum entsprechende Anzahl von Temperaturmessorten und damit eine zuverlässigere sowie genauere Temperaturinformation, wobei die einzelnen Temperaturen entweder mit Bezug auf den jeweiligen Messort ausgewertet oder für die Bildung eines Durchschnittswertes genutzt werden können. Da die Temperaturmessfunktion in den Positionssensoren baulich integriert ist, ergibt sich auch im Wesentlichen kein größerer Einbauraumbedarf. Die Integration von Mitteln zur Temperaturerfassung mit einem Positionssensor kann auf unterschiedliche Weise erfolgen. Gemäß einer ersten Ausgestaltung der Erfindung ist vorgesehen, dass zumindest einer der Positionssensoren mit einem herkömmlichen Temperatursensorelement, beispielsweise einem bekannten NTC-Element baulich integriert ist. Da Temperatursensorelemente recht kleine Abmessungen haben, lassen sich diese leicht und mit geringen zusätzlichen Kosten in oder am Gehäuse eines Positionssensors anordnen, ohne dessen Abmessungen wesentlich zu verändern. To determine the temperature at different locations in the transmission housing at least two such combined position and temperature sensors are installed and used. Obtained in this way one of the number of provided position sensors and their distribution over the gear housing housing interior corresponding number of Temperaturmessorten and thus a more reliable and more accurate temperature information, the individual temperatures either evaluated with respect to the respective location or used for the formation of an average value can be. Since the temperature measurement function is structurally integrated in the position sensors, there is essentially no greater installation space requirement. The integration of means for temperature detection with a position sensor can be done in different ways. According to a first embodiment of the invention, it is provided that at least one of the position sensors is structurally integrated with a conventional temperature sensor element, for example a known NTC element. Since temperature sensor elements have rather small dimensions, they can be easily and with little additional cost in or on the housing of a position sensor, without significantly changing the dimensions thereof.
Weiter besteht die Möglichkeit, einen Positionssensor mit einem damit direkt integrierten Temperatursensor zu verwenden. Ein derartig integrierter Sensor kann im Positionsmesselement selbst enthalten sein oder in einer Steuerung auf einer elektronischen Leiterplatte dieses Sensors. It is also possible to use a position sensor with a directly integrated temperature sensor. Such an integrated sensor may be included in the position measuring element itself or in a controller on an electronic circuit board of this sensor.
Gemäß einer anderen Ausgestaltung der Erfindung ist zumindest einer der Positionssensoren mit Mitteln zur Temperaturkompensation ausgestattet. Auf diese Weise ist im Positionssensor eine Temperaturinformation enthalten, die ausgewertet werden kann. According to another embodiment of the invention, at least one of the position sensors is equipped with means for temperature compensation. In this way, temperature information is contained in the position sensor, which can be evaluated.
Weiter ist bevorzugt vorgesehen, dass das jeweilige Sensorgehäuse über eine zugeordnete Sensorleitung mit einem zentralen Verbindungsstecker verbunden ist. Auf diese Weise kann sowohl die Positionsinformation als auch die Temperaturinformation jeweils über nur eine Sensorleitung geleitet werden, so dass eine übermäßige Blockierung der Schnittstelle zur elektronischen Getriebesteuereinheit vermeidbar ist. Further, it is preferably provided that the respective sensor housing is connected via an associated sensor line with a central connector. In this way, both the position information and the temperature information can each be routed via only one sensor line, so that excessive blocking of the interface to the electronic transmission control unit can be avoided.
Über die einem integrierten Positionssensor zugeordnete Sensorleitung können Positionssignale und Temperatursignale als zwei getrennte Analogsignale oder Digitalsignale der elektronischen Getriebesteuereinheit zugeführt werden. Position signals and temperature signals may be supplied as two separate analog or digital signals to the electronic transmission control unit via the sensor line associated with an integrated position sensor.
Ein anderer Weg der Datenübertragung sieht vor, dass über die einem integrierten Positionssensor zugeordnete Sensorleitung ein digitales Ausgangssignal mit einer eine Positionsinformation und eine Temperaturinformation enthaltende kombinierte Information an die elektronische Getriebesteuereinheit geleitet wird. Ein Beispiel für ein geeignetes digitales Übertragungsprotokoll könnte zum Beispiel ein Standard-SENT-Protokoll oder dergleichen sein. Another way of data transmission provides that via the sensor line associated with an integrated position sensor, a digital output signal is supplied with a combined information containing position information and temperature information to the electronic transmission control unit. An example of a suitable digital transmission protocol could be, for example, a standard SENT protocol or the like.
Die Erfindung lässt sich anhand eines Ausführungsbeispiels weiter erläutern. Dazu ist der Beschreibung eine Zeichnung beigefügt. Deren einzige Figur zeigt schematisch eine Einrichtung 1 zum Erfassen von Betriebszuständen in einem Schaltgetriebe, die Positionssensoren mit integrierten Temperatursensoren aufweist. The invention can be further explained with reference to an embodiment. For this purpose, the description is accompanied by a drawing. The sole FIGURE shows schematically a device 1 for detecting operating states in a manual transmission which has position sensors with integrated temperature sensors.
Die Figur zeigt ein Getriebegehäuse 2 mit einem Getriebegehäuseflansch 5, an dem im vorliegenden Beispiel vier baugleiche, kombinierte Positionssensoren 4 angeordnet sind, von denen nachfolgend nur einer beispielhaft beschrieben wird. Der Positionssensor 4 hat die Aufgabe, die Schaltposition des diesem zugeordneten schaltbaren Getriebeelementes 6, beispielsweise einer Schaltgabel, zu erfassen und an eine elektronische Getriebesteuereinheit 8 zu übermitteln. The figure shows a transmission housing 2 with a transmission housing flange 5, on which four identical, combined position sensors 4 are arranged in the present example, of which only one example will be described below. The position sensor 4 has the task to detect the switching position of the switchable transmission element 6 associated therewith, for example a shift fork, and to transmit it to an electronic transmission control unit 8.
Der Positionssensor 4 weist ein Gehäuse 3 auf, in dem zusätzlich zu einem Messmittel 9 für die Positionsmessung auch Mittel 10 zur Temperaturmessung, beispielsweise ein herkömmliches Temperatursensorelement 1 1 , baulich integriert sind. Die Positionsinformation des Positionssensors 4 sowie die Temperaturinformation des Temperatursensorelements 1 1 werden über eine gemeinsame Sensorleitung 12 an einen zentralen Verbindungsstecker 14 geleitet, von dem diese Informationen zur Auswertung an die elektronische Getriebesteuereinheit 8 weiterleitbar sind. The position sensor 4 has a housing 3, in which in addition to a measuring means 9 for the position measurement and means 10 for temperature measurement, for example, a conventional temperature sensor element 1 1, are structurally integrated. The position information of the position sensor 4 and the temperature information of the temperature sensor element 1 1 are passed via a common sensor line 12 to a central connector 14, from which this information can be forwarded to the electronic transmission control unit 8 for evaluation.
Wie bereits ausgeführt wurde, sind die in der Figur dargestellten integrierten Positionssensoren 4 baulich und funktional gleich, so dass sie nicht im Einzelnen beschrieben werden müssen. Wie weiter vorne beschrieben wurde, können die Mittel 10 zur Temperaturmessung auch als Mittel zur Temperaturkompensation des Positionssensors 4 ausgebildet sein, so dass das über die Sensorleitung 12 geleitete Signal eine Positionsinformation und eine Temperaturinformation enthält, die in der elektronischen Getriebesteuereinheit ausgewertet werden. As already stated, the integrated position sensors 4 shown in the figure are structurally and functionally the same, so that they do not have to be described in detail. As described above, the means 10 for temperature measurement can also be designed as a means for temperature compensation of the position sensor 4, so that the signal conducted via the sensor line 12 contains position information and temperature information which are evaluated in the electronic transmission control unit.
