Eine erfindungsgemäße Anordnung der Impulsmarken sowie die Auswertung des Drehmomentes auf Basis eines Kennfeldes, in welchem die Einflüsse der übertragenden Federn und der wirkenden Reibmomente enthalten sind, ist im Stand der Technik nicht vorgesehen.An arrangement according to the invention the pulse marks and the evaluation of the torque on the basis a map in which the influences of the transmitting springs and the acting friction moments are not in the prior art intended.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Drehmomentermittlung bei einer Antriebseinheit zu schaffen, die das übertragene Drehmoment auf Basis der relativen Verdrehung zweier federnd gekoppelter Schwungmassen ermittelt, wobei mit geringem Auswerteaufwand ein Drehmoment sehr genau ermittelt wird.The invention has for its object a Device for torque determination in a drive unit create the transmitted torque based on the relative rotation of two spring-loaded flywheels determined, with a very low evaluation effort a torque is determined exactly.
Erfindungsgemäß wird dies durch die im kennzeichnenden Teil des Hauptanspruches genannten Mittel erreicht, wenn der Verbrennungsmotor über ein Zweimassen-Schwungrad mit zwischengeschalteten, federnden Elementen an den Abtriebsstrang der Antriebseinheit angekoppelt ist. Dabei werden in einem Kennfeld die Ein flüsse der übertragenden Federn und der wirkenden Reibmomente berücksichtigt. Zur Auswertung brauchen dabei an beiden Massen des Schwungrades nur Impulsmarken angeordnet werden, die im un- oder wenig belasteten Zustand – z. B. Leerlauf – des Antriebsstranges in konstantem Bezugswinkel zueinander stehen. Diesen Impulsmarken ist ein gemeinsamer oder je ein Impulsaufnehmer ortsfest zuzuordnen.According to the invention, this is characterized by Part of the main claim reached when the internal combustion engine has a Dual Mass Flywheel with intermediate, springy elements on the drive train the drive unit is coupled. Here are in a map the influences the transferring Springs and the acting friction moments are taken into account. To the results need only pulse marks arranged on both masses of the flywheel be in the unloaded or little loaded state - e.g. B. Idle - des Drive train are at a constant reference angle to each other. this Pulse marks is a common or a fixed pickup assigned.
Die Erfindung nutzt in einfacher Weise die präzis abgestimmten Federn zwischen den zwei Massen des Zweimassen-Schwungrades zur Drehmomentermittlung. Damit entfallen zusätzliche mechanische Anordnungen zur Drehmomentermittlung. Die weiteren Ausgestaltungen der Erfindung gemäß der Unteransprüche sind in der Beschreibung im Zusammenhang erläutert.The invention uses in simpler Be precise coordinated springs between the two masses of the two-mass flywheel for torque determination. This eliminates the need for additional mechanical arrangements for torque determination. The further refinements of the invention according to the subclaims explained in context in the description.
Anhand einer Zeichnung wird ein Ausführungsbeispiel der Erfindung erläutert.An exemplary embodiment is illustrated by a drawing of the invention explained.
