PROBLEM TO BE SOLVED: To suppress slide when abnormality occurs on a power converter of a railway vehicle.SOLUTION: An instruction acquisition part 11 acquires a brake instruction including deceleration, and a variable load detector 12 detects a load of a vehicle. A required brake force calculation part 13 calculates required brake force from the load of the vehicle and the deceleration. An abnormality detection part 15 detects abnormality of a power converter 22 for driving an electric motor 23. A mechanical brake force calculation part 14 calculates mechanical brake force according to the required brake force and electric brake force generated by the electric motor 23, and sends a mechanical brake force instruction value indicating mechanical brake force to the mechanical brake 24. The mechanical brake force calculation part 14 increases mechanical brake force of a vehicle different from a vehicle on which the power converter 22, in which abnormality is detected, is mounted according to the electric brake force which decreases due to abnormality of the power converter 22, when detecting abnormality on the abnormality detection part 15, and sends the mechanical brake force instruction value indicating the increased mechanical brake force to the mechanical brake 24.SELECTED DRAWING: Figure 1
【課題】鉄道車両の電力変換器に異常が生じた場合における滑走を抑制する。【解決手段】指令取得部11は減速度を含むブレーキ指令を取得し、応荷重検出器12は車両の荷重を検出する。必要ブレーキ力算出部13は減速度および車両の荷重から必要ブレーキ力を算出する。異常検出部15は電動機23を駆動する電力変換器22の異常を検出する。機械ブレーキ力算出部14は、必要ブレーキ力と電動機23が生じさせる電気ブレーキ力との差分に応じて機械ブレーキ力を算出し、機械ブレーキ力を示す機械ブレーキ力指令値を機械ブレーキ24に送る。機械ブレーキ力算出部14は、異常検出部15で異常を検出した場合に、電力変換器22の異常により減少する電気ブレーキ力に応じて、異常が検出された電力変換器22が搭載される車両と異なる車両の機械ブレーキ力を増加させ、増加させた機械ブレーキ力を示す機械ブレーキ力指令値を機械ブレーキ24に送る。【選択図】図1
