The invention discloses an elevator door opening and closing resistance detection and driving force compensation method, which relates to the technical field of elevator control, and is characterized in that the door opening and closing driving force is compensated in advance by detecting the change of the elevator door opening and closing resistance in real time, and the inhibition effect of the resistance on the door on the door movement is counteracted in advance; the response capability of the door control system to a speed instruction is improved; according to the elevator door opening and closing resistance detection and driving force compensation method, hardware equipment and related signal acquisition algorithms do not need to be additionally added, only resistance and compensation current processing algorithms need to be carried out, and therefore the hardware cost is not increased; the detection precision reaches the whole stroke of the elevator door, the detection range covers each floor and door
