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

    【課題】鉄道車両のドアの移動方向の水平面に対する傾斜角度を考慮してドアの開閉動作の制御やその開閉動作に関する異常の診断等を行うことが可能な技術を提供する。【解決手段】本開示の一実施形態に係るパラメータ同定方法は、情報処理装置70が、鉄道車両のドア40を開閉駆動する電動機30が無負荷状態でドア40の開動作及び閉動作のそれぞれに相当する動作を一定の速度により実施したときの推力のデータを取得するステップS102と、情報処理装置70が、電動機30が有負荷状態でドア40を駆動し、ドア40の開動作及び閉動作のそれぞれを一定の速度で実施させたときの推力のデータを取得するステップS104と、情報処理装置70が、ステップS102,S104で取得されるデータに基づき、ドア40の開閉動作に関する力学モデルにおけるドア40の移動方向の水平面に対する傾斜角度のパラメータsinθを同定するステップS108と、を含む。【選択図】図3
