Abstract
A method for controlling a closing movement of a door of an elevator car in the event of a power failure uses the door drive and an electrical energy store. During normal operation of the door by the door drive, electrical energy is buffered in the energy store. In response to a power failure when the door is open, a closing mechanism begins to close the door and the stored electrical energy is provided as backup energy to the door drive by a control device to decelerate the closing movement.
