Abstract

Die Erfindung betrifft eine Vorrichtung zur Drehmomentadaption, bei der eine Berechnungseinheit vorgesehen ist, die aus Kennfeld- und/oder Sensoreingangsgrößen, wie der Motortemperatur, der Last oder der Motordrehzahl, und anhand eines Motormomentenmodells ein Motormoment ermittelt.The invention relates to a device for torque adaptation, in which a calculation unit is provided, which consists of map and / or sensor input variables, such as engine temperature, load, or engine speed, and using one Engine torque model determines an engine torque.

Zur Verbesserung der Genauigkeit der Motormomentenbestimmung ist ein Sensor (18) zum Erfassen eines an einer zwischen dem Verbrennungsmotor (10) und den angetriebenen Rädern angeordneten Antriebswelle (14) anliegenden Moments vorgesehen, wobei der Sensor (18) ein dem Moment entsprechendes Signal für die Berechnungseinheit erzeugt und die Berechnungseinheit derart ausgebildet ist, daß das aus dem Modell resultierende Motormoment (MdMod) in Abhängigkeit von dem erfaßten Moment (MdAntr) korrigierbar ist.

Figure 00000001
To improve the accuracy of the engine torque determination, a sensor (18) is provided for detecting a torque applied to a drive shaft (14) arranged between the internal combustion engine (10) and the driven wheels, the sensor (18) providing a signal corresponding to the torque for the calculation unit generated and the calculation unit is designed such that the engine torque resulting from the model (Md Mod ) can be corrected as a function of the detected torque (Md Antr ).
