Abstract
A method for operating an electric machine for a vehicle. A target torque of the electric machine is regulated during a driving process depending on a detected time-dependent rotational speed of the electric machine. In the process, the detected rotational speed is differentiated by means of a first high-pass filter over time, the detected rotational speed is then differentiated again over time in a limited manner to positive rotational speed values and using a second high-pass filter, and the target torque is regulated depending on the output value of the second high-pass filter.
