METHOD AND DEVICE FOR DETERMINING THE POSITION OF A MOBILE CLOSING PART OF A VEHICLE

摘要

The invention relates to 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 means of 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.
