Abstract
Description
Die Erfindung betrifft ein Automatgetriebe nach dem Oberbegriff des Anspruchs 1.The The invention relates to an automatic transmission according to the preamble of Claim 1.
Fahrzeuge benötigen Getriebe, um Drehmomente und Drehzahlen zu wandeln. Aufgabe eines Fahrzeuggetriebes ist es, das Zugkraftangebot eines Antriebsaggregats umzusetzen. Die hier vorliegende Erfindung betrifft ein Automatgetriebe. Im Sinne der hier vorliegenden Erfindung sollen unter dem Begriff Automatgetriebe alle Getriebe mit einem automatisierten Gangwechsel und Stufenlosgetriebe verstanden werden.vehicles need Gearbox to convert torques and speeds. Task of a vehicle transmission is to implement the traction power supply of a drive unit. The present invention relates to an automatic transmission. in the For the purposes of the present invention, the term automatic transmission is intended all transmissions with an automated gear change and continuously variable transmission be understood.
Aus dem Stand der Technik bekannte Automatgetriebe verfügen über mehrere Druckregler sowie eine elektronische Getriebesteuerungseinrichtung, wobei die elektronische Getriebesteuerungseinrichtung einen durch die Druckregler fließenden, elektrischen Strom regelt. Jeder Druckregler ist über einen gemeinsamen Sicherheitsschalter der Getriebesteuerungseinrichtung, der in einen Versorgungspfad der Druckregler geschaltet ist, an eine Batterie angeschlossen. Weiterhin ist jeder Druckregler über eine individuelle Endstufe der Getriebesteuerungseinrichtung, die in einen Massepfad der Druckregler geschaltet sind, an ein Massepotential angeschlossen. Aus dem Stand der Technik bekannte Automatgetriebe verfügen weiterhin über Strommesseinrichtungen, die den durch die Druckregler fließenden, elektrischen Strom messen, wobei die Strommesseinrichtungen bei aus dem Stand der Technik bekannten Automatgetrieben in den Massepfad der Druckregler geschaltet sind.Out The prior art known automatic transmissions have several Pressure regulator and an electronic transmission control device, wherein the electronic transmission control device by a the pressure regulators are flowing, electrical Electricity regulates. Each pressure regulator is via a common safety switch the transmission control device, in a supply path the pressure regulator is connected to a battery. Furthermore, each pressure regulator is over one individual output stage of the transmission control device, which in a ground path of the pressure regulator are connected to a ground potential connected. Automatic transmission known from the prior art feature continue over Current measuring devices that the flowing through the pressure regulator, electrical Measure current, with the current measuring devices at standstill known in the art automatic transmissions in the mass path of the pressure regulator are switched.
Bei solchen, aus dem Stand der Technik bekannten Automatgetrieben können hochohmige Kurzschlüsse nach Masse an den Druckreglern oder an den Endstufen nicht sicher erkannt werden. Dies ist von Nachteil.at such known from the prior art automatic transmissions can high-impedance shorts after Mass at the pressure regulators or at the power amplifiers not reliably detected become. This is a disadvantage.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Automatgetriebe zu schaffen. Dieses Problem wird durch ein Automatgetriebe gemäß Anspruch 1 gelöst.Of these, Based on the present invention, the problem underlying to create a novel automatic transmission. This problem is going through an automatic transmission according to claim 1 solved.
Erfindungsgemäß sind Strommesseinrichtungen, die den durch die Druckregler fließenden, elektrischen Strom messen, in den Versorgungspfad der Druckregler geschaltet.According to the invention, current measuring devices, the electrical current flowing through the pressure regulators measure, connected to the supply path of the pressure regulator.
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, die Strommesseinrichtungen, die den durch die Druckregler fließenden, elektrischen Strom messen, in den Versorgungspfad der Druckregler zu schalten. Hochohmige Kurzschlüsse nach Masse am Druckregler oder an den Endstufen können so unter allen Bedingungen sicher erkannt werden. Die Strommesseinrichtungen können durch die Endstufen fließende Ströme ebenso wie Fehlerströme, die auf anderem Weg nach Masse führen, sicher erfassen. Hierdurch wird eine bei aus dem Stand der Technik bekannten Automatgetrieben herrschende Diagnoselücke geschlossen.in the For the purposes of the present invention, it is proposed that the current measuring devices, the flowing through the pressure regulators, measure electrical current in the supply path of the pressure regulator to switch. High impedance short circuits to Mass at the pressure regulator or at the power amplifiers can thus under all conditions be reliably recognized. The current measuring devices can by the Power amplifiers flowing streams as well as fault currents, which lead by other means to mass, capture safely. This will be one of the prior art known automatic gearbox prevailing diagnostic gap closed.
