摘要

The invention relates to a method for controlling an electric machine (3) of an electrified exhaust gas turbocharger (2) operable in a generator mode or in a motor operation in a drive unit (100) with a supercharged internal combustion engine (1) and a stepped transmission, comprising the method steps: - Recognizing a gear change or an impending gear change towards a higher gear, - Determining a current operating state of the electric machine (3), - Verification of the determined current operating state of the electric machine (3) with regard to the detected gear change or the recognized, imminent gear change to a higher gear and - transferring the electric machine (3) in the regenerative operation or weitererbetreiben the electric machine (3) in the regenerative mode when a gear change is detected towards a higher gear or - transferring the electric machine (3) in the regenerative Operation or further operation of the electric machine (3) in regenerative operation when an impending gear change is detected towards a higher gear. The invention further comprises a system (200) for operating an electric machine (3) of an electrified exhaust gas turbocharger (2), a computer program product, a drive unit (100), a motor vehicle and a control and / or regulating device (50).
