To provide an abnormality determining device which can appropriately detect the abnormality of a switch circuit.SOLUTION: Provided is a control device 21 applied to a first switch circuit SW1 provided in an electricity conducting path L1, and determining the abnormality of the switch circuit. The control device comprises: a setting unit which when on/off of the first switch circuit SW1 is switched, sets whether the switching is from an on state to an off state or from an off state to an on state and sets the sequence of on/off switching of two first switching elements 30A, 30B and two second switching elements 30C, 30D on the basis of a current direction at the switching time; a current acquisition unit for acquiring a current flowing through a switch being an abnormality determination object when on/off of each switching element 30 is switched in accordance with the switching sequence; and an abnormality determination unit for carrying out the abnormality determination of a circuit unit being the abnormality determination object, on the basis of the acquisition current acquired by the current acquisition unit.SELECTED DRAWING: Figure 3

    【課題】適切にスイッチ回路の異常を検出することができる異常判定装置を提供することにある。【解決手段】通電経路L1に設けられた第1スイッチ回路SW1に適用され、該スイッチ回路の異常を判定する制御装置21であって、第1スイッチ回路SW1のオンオフが切り替えられる場合において、その切替がオン状態からオフ状態への切替とオフ状態からオン状態への切替とのいずれであるかと、その切替時の電流の向きとに基づいて、前記2つの第1スイッチング素子30A,30Bと2つの第2スイッチング素子30C,30Dとのオンオフの切替順序を設定する設定部と、切替順序に応じて各スイッチング素子30のオンオフが切り替えられる場合に、異常判定対象となるスイッチに流れる電流を取得する電流取得部と、電流取得部により取得された取得電流に基づいて、異常判定対象となる回路部の異常判定を実施する異常判定部と、を備える。【選択図】 図3
