Bei einem Verfahren zur Ermittlung der Raddrehzahl eines Fahrzeugrades in einem Fahrzeug mit elektrischem Antriebsmotor wird die Motordrehzahl des elektrischen Antriebsmotors mittels eines Rotorsensors bestimmt und unter Berücksichtigung einer Getriebeübersetzung eines Getriebes zwischen dem elektrischen Antriebsmotor und einem Fahrzeugrad zur Raddrehzahlermittlung herangezogen. In a method for determining a wheel rotational speed of a wheel in a vehicle having an electric drive motor, a motor rotational speed of the electric drive motor is determined by means of a rotor sensor, and the motor rotational speed is used for the wheel rotational speed determination taking into account a transmission speed ratio of a transmission between the electric drive motor and the wheel.
