Abstract:
A method and system for controlling a movable door associated with a passenger compartment, the door moveable between an opened position and a closed position configured to provide access to, or egress from, the passenger compartment. The method includes monitoring a landing area of the elevator door with at least one sensor, and determining a level of urgency of an approaching passenger based on the information from the at least one sensor. If the level of urgency exceeds a predetermined threshold, modifying a closing of the elevator door based on the level of urgency. The method may also include modifying a closing speed of the elevator door if the level of urgency exceeds a predetermined threshold.
