Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung eines thermischen Zustandes eines Elektromotors in einem Hybridantrieb eines Kraftfahrzeuges, wobei als Elektromotor vorzugsweise eine permanent erregte Synchronmaschine verwendet wird, bei welchem eine mittlere Statorwicklungstemperatur in einem Temperaturmodell zur Bestimmung eines thermischen Zustandes des Elektromotors berechnet wird. Bei einem Verfahren, bei welchem die Genauigkeit des Temperaturmodells verbessert wird, wird aus mindestens einem, an dem Elektromotor gemessenen elektrischen Parameter eine geschätzte mittlere Statorwicklungstemperatur bestimmt, welche mit der berechneten mittleren Statorwicklungstemperatur zur Kalibrierung des Temperaturmodells verglichen wird.
