METHOD FOR OPERATING AN ELECTRIC MACHINE, DEVICE, DRIVE DEVICE, AND MOTOR VEHICLE

The invention relates to 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 ().
