摘要

A method for fault recognition in an electric machine controlled by an inverter in a motor vehicle, in which the phase currents of the electric machine are ascertained, in particular ascertained by measuring, and a fault is recognized if at least one of the phase currents or a variable derived therefrom, exceeds a predefined upper threshold value, the upper threshold value being established as a function of operating parameters of the motor vehicle, in particular of the electric machine and/or of the inverter.
