Abstract:
In a method and a device for determining the position of a closing part of a vehicle, that can be moved by a direct-current motor, a motor current signal is derived from the direct-current motor and converted into a digital signal by an analog-digital converter. The signal is filtered and forwarded to a position counter for counting the current ripple. The scanning frequency of the analog-digital converter is modified according to the rotational speed of the direct-current motor.
