Abstract: A method of controlling an elevator door dwell time includes obtaining a predefined load weight value; obtaining a load weight value from a load weight sensor coupled to an elevator car; comparing the load weight value to the predefined load weight value to generate a difference; and adjusting the elevator door dwell time in response to the difference to define an adjusted elevator door dwell time.

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.
