To provide a technique capable of controlling an opening/closing operation of a door of a railway vehicle by taking into account an inclination angle with respect to a horizontal surface in a moving direction of the door and diagnosing abnormality related to the opening/closing operation.SOLUTION: A parameter identification method includes: step S102 in which an information processing device 70 acquires thrust data when an electric motor 30 for driving the opening/closing of a door 40 of a railway vehicle performs operation corresponding to each of the opening operation and the closing operation of the door 40 under no-load condition at a constant speed; step S104 in which the information processing device 70 acquires the thrust data when the electric motor 30 drives the door 40 under a loaded condition and the opening operation and the closing operation of the door 40 are respectively performed at a constant speed; and step S108 in which the information processing device 70 identifies a parameter sinθ of an inclination angle with respect to a horizontal surface in a moving direction of the door 40 in a dynamic model with respect to the opening/closing operation of the door 40 based on the data acquired in steps S102, S104.SELECTED DRAWING: Figure 3
