Zusammenfassung:SOLUTION: A reuse determination system of a power unit for propelling a vehicle includes an acquisition section that acquires operation history data including torque data and number of rotations data of a rotating electrical machine, an estimation section that estimates a load of each of a plurality of components constituting the power unit, based on at least one of the torque data and the number of rotations data, and a determination section that compares, for each of the plurality of components constituting the power unit, each load estimated by the estimation section with a threshold defined for each component, and determines that the power unit is to be reused when the load of each of the plurality of components estimated by the estimation section is equal to or less than the threshold defined for each, and that it is to be reused by performing component replacement of the power unit when there exists a component for which a load exceeding the threshold defined for each is estimated among the plurality of components.SELECTED DRAWING: Figure 1 【解決手段】車両を推進するための動力装置のリユース判定システムは、回転電機のトルクデータ及び回転数データを含む動作履歴データを取得する取得部と、トルクデータ及び回転数データの少なくとも一方に基づいて、動力装置を構成する複数の部品のそれぞれの負荷を推定する推定部と、動力装置を構成する複数の部品のそれぞれについて、推定部により推定されたそれぞれの負荷とそれぞれの部品に定められた閾値とを比較し、推定部により推定された複数の部品のそれぞれの負荷がそれぞれに定められた閾値以下である場合に動力装置をリユースし、複数の部品のうちそれぞれに定められた閾値を超える負荷が推定された部品が存在する場合に動力装置の部品交換を行ってリユースすると判定する、判定部とを備える。【選択図】図1
