PROBLEM TO BE SOLVED: To provide an elevator door controlling device capable of spontaneously detecting increase of overload due to a wind pressure, reflecting it to the control, and correcting limit of a door opening/closing force according to an increase volume of the overload after detection. SOLUTION: In this elevator door control system, a door installed at an entrance/exit of an elevator is driven to be opened/closed by a motor. This system comprises means for finding a prediction pattern of increase of overload due to a wind pressure based on a difference between an outside temperature and a temperature in an elevator shaft, comparing it with an increase pattern from a normal load time at a current torque command value and detecting the increase of the overload due to the wind pressure, and means for correcting a torque limit value based on the prediction pattern of the increase of the overload when the overload due to the wind pressure is detected.
