Abstract

See full text

In order to ascertain the actuating position of a vehicle part that is moved by an electric actuating motor via an actuating mechanism, an angle of rotation correlating with the number of motor shaft rotations during the actuation process or a motor signal correlated therewith are ascertained during an actuation process. An actuating position measure for the actuating position of the vehicle part is derived from the angle of rotation or the motor signal correlating therewith. During this process, an unloaded angle of rotation, through which the motor shaft rotates during an initial no-load phase of the actuation process without motion of the vehicle part is compensated by a predetermined correction term. The correction term is changed according to a stored dependency on a characteristic quantity for the age of the actuating mechanism.
