Abstract

See full text

An elevator car includes at least one elevator door, a door drive for actuating the elevator door, a sensor for detecting the motor power of the door drive and an evaluating unit that determines, based on the motor power detected, whether there is a deviation in the drive force actuating the elevator door from a reference drive force. The evaluating unit determines whether a deviation occurs due to an obstacle in contact with the elevator door or due to altered external conditions, particularly due to altered pressure conditions and/or air flow.
