Generator characteristics determining model for motor vehicle, has generator characterized by equivalent circuit diagram, where characteristics are determined based on parameters of diagram having leakage and primary inductances

The model has a generator that is characterized by an equivalent circuit diagram, where the generator characteristics are determined based on parameters of the diagram. The diagram has a coil resistance for characterizing resistance of a fixed coil, leakage and primary inductances and a resistance for characterizing iron losses. A voltage supply produces a revolving field voltage induced by an energizing current of a rotor of a stator. An independent claim is also included for a method for determining characteristics of a generator in a motor vehicle. Die vorliegende Erfindung betrifft ein Generatormodell und ein Verfahren zur Ermittlung von Kenngrößen eines Generators in einem Kraftfahrzeug, wobei der Generator in dem Generatormodell durch ein Ersatzschaltbild charakterisiert ist und die Generatorkenngrößen in Abhängigkeit von Parametern des Ersatzschaltbildes ermittelbar sind.
