Patent abstract
The thermal monitoring of a converter for an electric motor of a vehicle should be improved. Therefore, the invention relates to a method in which the temperature of the converter is measured. In addition, the output power of the converter is determined. The temperature of the converter is estimated using a thermal model of the converter having the output power as an input variable. The estimated temperature is compared with the measured temperature, and a corresponding monitoring signal is provided. Thus, a deviation of the measured temperature for the calculated temperature and thus a corresponding error in the cooling system can be detected even in the partial-load range.
