Automatisierte Schaltsysteme bestehen hinsichtlich ihrer Hauptkomponenten aus konventionellen, gegebenenfalls auch manuell betätigbaren Schaltsystemen, bei denen das Betätigen der Schalt- und/oder Anfahrkupplung zwischen Antriebsmotor und Getriebe sowie das Wahlen und Schalten von Getriebegängen über entsprechende Betätigungsmittel automatisiert erfolgt. Diese Betätigungsmittel sind üblicherweise als hydraulisch oder pneumatisch betätigbare Kolben-Zylinder-Anordnungen oder als elektrische Aktuatoren ausgebildet, welche auf Stell mittel für die genannten Getriebefunktionen einwirken. Die Stellmittel können am oder im Getriebe angeordnet sein.Automated switching systems consist in terms of their main components of conventional, possibly also manually operable switching systems in which the actuation of the shift and / or starting clutch between the drive motor and transmission and the selection and switching of gears via corresponding actuating means is automated. These actuating means are usually designed as hydraulically or pneumatically actuated piston-cylinder arrangements or as electrical actuators, which act on adjusting medium for said gear functions. The adjusting means may be arranged on or in the transmission.
Zur Ansteuerung von hydraulischen bzw, pneumatischen Betätigungsmitteln sind Druckerzeugungs- und Steuerungsvorrichtungen notwendig, die gemäß dem Stand der Technik eine Hydraulik- bzw. Pneumatikpumpe als Druckerzeugungsvorrichtung, einen Druckspeicher, eine hydraulische bzw. pneumatische Steuerungseinheit mit Steuerungsventilen und Sensoren umfassen, welche mit einer zentralen Steuerungs- und Regelungsvorrichtung in Verbindung stehen und von dieser nach dort abgespeicherten Steuerungs- und Regelungsfunktionen ansteuerbar sind.For the control of hydraulic or pneumatic actuating means pressure generating and control devices are necessary, which comprise according to the prior art, a hydraulic or pneumatic pump as a pressure generating device, a pressure accumulator, a hydraulic or pneumatic control unit with control valves and sensors, which with a central control - And control device in connection and are controlled by this stored there control and regulation functions.
In Getrieben wird eine Vielzahl von Sensoren verwendet, die im Allgemeinen als Einzelsensoren eingebaut oder auf Mechatronikmodulen befestigt werden. Ober solche Sensoren werden beispielsweise Drehzahlen, Drücke, Temperaturen und/oder Wege sensiert Hierbei ist eine Vielzahl von Leitungen und Verbindungen notwendig. Oft sind dies lange Kabelverbindungen, die aufwendig anzuordnen und wenig zuverlässig sind.Gearboxes use a variety of sensors, which are generally installed as individual sensors or mounted on mechatronic modules. Above such sensors, for example, speeds, pressures, temperatures and / or paths sensed Here is a variety of lines and connections necessary. Often these are long cable connections, which are complicated to order and are not very reliable.
Ein automatisiertes Schaltsystem weist verschiedene Sensoren auf, mit welchen alle relevanten Informationen zum auomatisierten Schalten und Kuppeln erfasst werden können. Die Sensorinformationen werden meist über verschiedenste Schnittstellenleitungen an eine Steuerungs- und Regelungseinheit übertragen.An automated switching system has various sensors with which all relevant information for the auomatized switching and coupling can be detected. The sensor information is usually transmitted via a variety of interface lines to a control and regulation unit.
Beispielsweise verfügt ein automatisiertes Schaltsystem über eine Fahrerbefä- tigungseinrichtung, die den Fahrerwunsch für die Getriebefunktion erfasst sowie Drehzahlsensoren, welche die Drehzahlen einer Getriebeeingangswelle, einer Getriebeabtriebswelle und/oder der Motordrehzahl detektieren. Über Temperatursensoren können Temperaturen an systemspezifischen Komponenten sowie die Temperatur eines Getriebeöls oder eines Kühlsystems erfasst werden. Drucksensoren sensieren beispielsweise einen Druck in einem Hydraulik- bzw. Pneumatikkreislauf.For example, an automated shift system has a driver handling device which detects the driver's intention for the transmission function, and rotational speed sensors which detect the rotational speeds of a transmission input shaft, a transmission output shaft and / or the engine rotational speed. Temperatures on system-specific components as well as the temperature of a transmission oil or a cooling system can be recorded via temperature sensors. Pressure sensors sense, for example, a pressure in a hydraulic or pneumatic circuit.
Ebenso können über Sensoren die Betätigung eines Fahrpedals, eines Bremspedals sowie die Betätigung eines Schalthebels detektiert werden, Die Sensorinformationen, wie beispielsweise das Motormoment, die Drosselklappenstellung, die Drehzahl von Antriebsmotor und/oder Getriebe, die aktuelle Übersetzungsstufe des Getriebes sowie die Betätigung von Fahrpedal, Bremspedal und Schalthebel, werden hierbei über Signalleitungen an eine Steuerungs- und Regelungseinheif weitergeleitef.The sensor information, such as the engine torque, the throttle position, the rotational speed of the drive motor and / or transmission, the current gear ratio of the transmission and the operation of the accelerator pedal, Brake pedal and shift lever, are here weiterleiteitef signal lines to a control and Regelungseinheef.
Aus diesen Signalen errechnet die Steuerungs- und Regelungseinheif die Schaltpunkte und steuert die Schaltungs- und Kupplungsvorgänge automatisch.From these signals, the control and regulation unit calculates the switching points and controls the switching and coupling processes automatically.
In der DE 199 15471 A1 ist eine Vorrichtung zum Messen einer Getrie- beöltemperatur in einem Kraftfahrzeug offenbart. Ein Temperatursensor ist außerhalb des Ölsumpfes in einem Getriebegehäuse angeordnet und wird beim Betrieb des Getriebes mit Öl aus einem Ölsumpf benetzt. Dazu wird in einer vorteilhaften Ausgestaltung das Ol durch rotierende Elemente des Getriebes aus dem Ölsumpf aufgewirbelt, beispielsweise durch Zahnräder des Getriebes. In einer vorteilhaften Ausgestaltung ist der Temperatursensor in unmittelbarer Nähe eines Drehzahlsensors mit rotierender Zählscheibe angeordnet, wodurch das Spritzöl durch die Zählscheibe mit dem Temperatursensor in Kontakt kommt. Der Drehzahlsensor und der Temperatursensor können in einem Getriebe-Schaltgerät, welches beispielsweise eine Elektronik und eine Schaltaktuatorik beinhaltet, integriert sein.DE 199 15471 A1 discloses a device for measuring a transmission oil temperature in a motor vehicle. A temperature sensor is located outside the oil sump in a transmission housing and is during operation of the gear unit, wets with oil from an oil sump. For this purpose, the oil is fluidized by rotating elements of the transmission from the oil sump, for example by gears of the transmission in an advantageous embodiment.

The speed sensor and the temperature sensor may be integrated in a transmission switching device, which includes, for example, electronics and a Schaltaktuatorik.
Nachteile des Standes der Technik sind, dass ein Antriebsstrang eines Kraftfahrzeuges eine Vielzahl von Einzelsensoren aufweist, welche über separate Signalleitungen mit einer Recheneinheit des Antriebstangs verbunden werden, beispielsweise mit einer Steuerungs- und Regelungseinheit (ECU). Solche Kabelverbindungen sind oft aufwendig zu realisieren und wenig zuverlässig. Des Weiteren ergibt sich durch Einzelsensoren eine Vielzahl von Schnittstellen in einem Kraftfahrzeug-Antriebsstrang.Disadvantages of the prior art are that a drive train of a motor vehicle has a plurality of individual sensors, which are connected via separate signal lines with a computing unit of the drive train, for example with a control and regulation unit (ECU). Such cable connections are often expensive to implement and not very reliable. Furthermore, individual sensors result in a multiplicity of interfaces in a motor vehicle drive train.
In der DE 196 30 155 A1 ist ein Automatgetriebe offenbart, welches einen modularen Aufbau besitzt. Durch den modularen Aufbau sind ein Getriebemechanik-Modul, ein Kupplungsbetätigungs-Modul, ein Druckversorgungs- Modul, ein Hydrauliksteuergeräte-Modul und ein Elektroniksteuergeräte-Modul austauschbar miteinander verbindbar. Das Hydrauliksteuergeräte-Modul ist derart ausgebildet, dass es alle für eine Kupplungs- und Schaltgetriebebetätigung notwendigen Sensoren und Aktuatoren und deren Ventile aufweist. Im Elektroniksteuergeräte-Modul werden alle Schaltbefehle für die Aktuatoren des Hydrauliksteuergeräte-Moduls erzeugt Bei dem modularen Automatgetriebe ist lediglich eine elektrische Schnittstelle zwischen dem Hydrauliksteuergeräte- Modul und dem Elektroniksteuergeräte-Modul notwendig, wodurch elektrische Leitungen eingespart werden können. Ein Nachteil dieser modularen Aufbauform ist, dass verschiedene Signale nicht mehr direkt über Sensoren erfasst werden können, sondern indirekt bestimmt werden müssen. Die Position der Kupplung kann beispielsweise nicht mehr über einen Positionssensor, sondern muss indirekt über den Druck in einem Geberzylinder festgestellt werden. Des Weiteren muss das Hydrauliksteuergeräte-Modul eine hydraulische Schnittstelle aufweisen, da im Hydrauliksteuergeräte-Modul nicht nur alle Sensoren, sondern auch die für eine Kupp- lungs- und Schaltgetriebebetätigung notwendigen Aktuatoren und Ventile enthalten sind.In DE 196 30 155 A1 an automatic transmission is disclosed, which has a modular structure. Due to the modular structure, a transmission mechanism module, a clutch actuation module, a pressure supply module, a hydraulic control unit module and an electronic control unit module are interchangeable connectable. The hydraulic control module is designed such that it has all the necessary for a clutch and gearbox actuation sensors and actuators and their valves. In the electronic control unit module all switching commands for the actuators of the hydraulic control module are generated in the modular automatic transmission, only an electrical interface between the hydraulic control module and the electronic control unit module is necessary, which electrical lines can be saved. A disadvantage of this modular design is that different signals can no longer be detected directly via sensors, but must be determined indirectly. The position of the clutch, for example, no longer a position sensor, but must be determined indirectly via the pressure in a master cylinder.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein automatisiertes Schaltsystem, insbesondere in einem Kraftfahrzeug darzustellen, bei welchem die Anordnung der Sensoren verbessert ist.The present invention has for its object to represent an automated switching system, in particular in a motor vehicle, in which the arrangement of the sensors is improved.
Die der Erfindung zugrunde liegende Aufgabe wird durch ein, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisendes, gattungsgemäßes automatisiertes Schaltsystem gelöstThe object underlying the invention is achieved by a, even the characterizing features of the main claim exhibiting, generic automatic switching system
Bei der Entwicklung von Mechatronikmodulen bieten sich oftmalig Möglichkeiten, verschiedene Sensoren in einem Sensormodul anzuordnen, welches an geeigneten Befestigungsstellen in oder an einem Getriebe angebracht werden kann. Durch geeignetes Zusammenfassen von Sensoren zu Sensormodulen ergeben sich handhabbare Bauteile, welche deutlich einfacher zu montieren sind als Einzelbauteile, deutlich weniger Schnittstellen aufweisen und auch im Servicefall einen hohen Reparaturerfolg gewährleisten. Außerdem können durch eine Anbindung an Aufbau-Verbindungsmodule unzuverlässige Kabelverbindungen eingespart werden. Erfindungsgemäß können alle möglichen Sensoren, wie beispielsweise Weg-, Positions-, Drehzahl-, Geschwindigkeits-, Temperatur-, Druck- und/oder Strömungssensoren, in einem Sensormodul angeordnet sein. Das Sensormodul kann derart ausgebildet sein, dass die im Sensormodul angeordneten Sensoren an verschiedenen Stellen in einem automatisierten Schaltsystem unterschiedliche Messgrößen aufnehmen können. Das erfindungsgemäße Sensormodul soll hierbei nicht auf eine bestimmte Kombinationsmöglichkeit von Sensoren beschränkt werden. Vielmehr soll eine sinnvolle Zusammenfassung von Sensoren ermöglicht werden. Hierbei kann es daher vorteilhaft sein, nicht alle Sensoren in einem Sensormodul unterzubringen, sondern entsprechende Sensoren auf mehrere Sensormodule aufzuteilen. Die verschiedenen Sensormodule können an geeigneten Befestigungsstellen im automatisierten Schaltsystem angebracht werden, beispielsweise an oder in einem Getriebe, Das Sensormodul kann beispielsweise aus einem einteiligen Gehäuse bestehen, welches öldicht ausgebildet ist. Ebenso ist es denkbar, dass das Gehäuse des Sensormoduls einen oberen Gehäuseteil und einen unteren Gehäuseteil aufweist, welche über beispielsweise Schraubverbindungen fest miteinander verbindbar und öldicht sind.In the development of mechatronic modules, it is often possible to arrange various sensors in a sensor module, which can be attached to suitable attachment points in or on a transmission. By suitable combination of sensors to sensor modules resulting in manageable components that are much easier to assemble than individual components, have significantly fewer interfaces and even in case of service to ensure a high degree of repair success. In addition, unreliable cable connections can be saved by a connection to connection modules. According to the invention, all possible sensors, such as position, speed, speed, temperature, pressure and / or flow sensors, may be arranged in a sensor module. The sensor module can be configured such that the sensors arranged in the sensor module can record different measured variables at different points in an automated switching system. In this case, the sensor module according to the invention should not be limited to a specific possibility of combining sensors. Rather, a meaningful summary of sensors should be made possible. It may therefore be advantageous not to accommodate all the sensors in a sensor module, but to divide corresponding sensors to a plurality of sensor modules. The various sensor modules can be attached to suitable attachment points in the automated switching system, for example, on or in a transmission, the sensor module may for example consist of a one-piece housing, which is formed oil-tight. It is also conceivable that the housing of the sensor module has an upper housing part and a lower housing part, which are firmly connected to each other and oil-tight, for example, by screw.
Des weiteren kann das Sensormodul derart ausgebildet sein, dass eine Auswerteelektronik für zumindest einzelne Sensoren direkt im Sensormodul integriert ist.Furthermore, the sensor module can be designed such that an evaluation electronics for at least individual sensors is integrated directly in the sensor module.
Im Folgenden wird das Grundprinzip der Erfindung, welche mehrere Ausführungsformen zulässt, an Hand einer Zeichnung beispielhaft näher erläutert.In the following, the basic principle of the invention, which permits several embodiments, is explained in more detail by way of example with reference to a drawing.
Die einzige Figur dieser Zeichnung zeigt ein Sensormodul 1 für ein automatisiertes Schaltsystem in einem Kraftfahrzeug. Das Sensormodul 1 ist aus einem einteiligen Gehäuse 3 gefertigt und weist ein Dichtelement 4 auf, welches beispielsweise als O-Ring ausgebildet ist und zur Abdichtung zu einem Getriebegehäuse dient. An einer oberen Seite 2 des Gehäuses 3 weist das Sensormodul 1 eine elektrische Schnittstelle 7 und Befestigungselemente 5, 6 auf. Durch die Befestigungselemente 5, 6 kann das Sensormodul 1 an geeigneten Befestigungsstellen an bzw. in einem Getriebe befestigt werden, beispielsweise über Schraubverbindungen. Das Sensormodul 1 weist Wegsensoren 8, 9, 10 und Drehzahlsensoren 11 , 12 auf. Des weiteren kann am Sensormodul 1 beispielsweise auch ein Öltemperatursensor angeordnet sein, welcher die Temperatur eines Getriebesumpfes erfasst (hier nicht dargestellt). Über die drei Wegsensoren 8, 9, 10 werden die Positionen von Schaltschienen 13, 14, 15 erfasst, wodurch eine aktuelle Getriebeübersetzung ermittelt werden kann. Der Drehzahlsensor 11 delektiert die Drehzahl eines Geberrades 16, welches beispielsweise auf einer Getriebehauptwelle angeordnet ist. Das Geberrad 16 kann vorzugsweise als Zahnrad oder als Lochblech ausgebildet sein. Über den Drehzahlsensor 12 wird die Drehzahl einer Schaltmuffe 17 delektiert, welche beispielsweise auf der Getriebehauptwelle drehfest aber axial verschiebbar angeordnet ist.The sole figure of this drawing shows a sensor module 1 for an automated shift system in a motor vehicle. The sensor module 1 is made of a one-piece housing 3 and has a sealing element 4, which is for example designed as an O-ring and serves to seal to a transmission housing. On an upper side 2 of the housing 3, the sensor module 1 has an electrical interface 7 and fastening elements 5, 6. By fastening elements 5, 6, the sensor module 1 can be attached to suitable attachment points on or in a transmission, for example via screw. The sensor module 1 has displacement sensors 8, 9, 10 and rotational speed sensors 11, 12. Furthermore, on the sensor module 1, for example, an oil temperature sensor can be arranged, which detects the temperature of a transmission sump (not shown here). About the three displacement sensors 8, 9, 10, the positions of shift rails 13, 14, 15 are detected, whereby a current transmission ratio can be determined. The speed sensor 11 detects the speed of a sensor wheel 16, which is arranged for example on a transmission main shaft. The encoder wheel 16 may preferably be formed as a gear or as a perforated plate. About the speed sensor 12, the speed of a shift sleeve 17 is detected, which, for example, on the transmission main shaft rotatably but axially displaceable.
