摘要：A method is specified for ascertaining an actuating position of a vehicle part thatcan be moved by an electric actuating motor. The speed of an actuating motor
correlated therewith is acquired in a time-resolved manner during an actuation process.An initial no-load phase of the actuation process is identified, during which the actuatingmotor rotates while overcoming the system tolerance of the actuating mechanismwithout motion of the vehicle part. An actuating position measure for the actuatingposition of the vehicle part is ascertained from the motor rotation, with this measurebeing corrected during the no-load phase. By averaging over time, a test quantity isascertained from the second derivative or the measured quantity correlating herewith.The end of the initial no-load phase is identified in this process when the test quantityexceeds a predetermined limit.
