The invention relates to a method and a device for detecting the rotation direction of a drive unit, especially of an adjustment drive (64) in a motor vehicle. Said device comprises a motor (12) the rotation direction of which can be reversed by means of switches (20). The speed of the motor (12) is detected by means of at least one incremental sensor signal (56) and is supplied to an evaluation unit (40), a digitized motor current state signal attributing the current motor current to the states -1, 0, +1 being used to evaluate the rotation direction. |
