The invention relates to a method for operating an electric machine (2) for a vehicle (3). A target torque of the electric machine (2) is regulated during a driving process depending on a detected time-dependent rotational speed of the electric machine (2). In the process, the detected rotational speed is differentiated by means of a first high-pass filter (5) 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 (8), and the target torque is regulated depending on the output value of the second high-pass filter (8).
