Abstract
A method of updating a stall threshold level of an elevator door to control a door stall occurring during opening or closing of the elevator door includes determining an exceptional motion count of a door based on at least one of a speed and an acceleration of the door, determining whether the door is stalled, based on a determined exceptional motion count of the door and a preset stall threshold level of the door, and re-determining the stall threshold level of the door according to the determination of whether the door is stalled.
