Title: METHOD FOR DETERMINING THE ROTATIONAL ANGLE IN AN ELECTRIC MOTOR
Abstract:
Presented and described is a method for determining the rotational angle (φ) in an electric motor, in particular in an electric motor of a window regulator of a motor vehicle, comprising the following steps: a) detecting at least one operating variable of the electric motor by means of a sensor (1), b) outputting the detected signal (UHall) by means of the sensor (1), and c) evaluating the output signal (UHall). In order to permit a reliable determination of the rotational angle even in adverse operating states, it is proposed that, in step b), an analogue signal (UHall) be output by the sensor (1).
