PROBLEM TO BE SOLVED: To determine a failure of a switch provided on a vehicular power supply device.SOLUTION: A vehicular power supply device comprises: an opening/closing switch SW1 which is switched between a conduction state in which a motor generator 16 and a lithium-ion battery 27 are connected to each other and a cut-off state in which the motor generator and the battery are separated from each other; an opening/closing switch SW2 which is switched between a conduction state in which the motor generator 16 and a lead-acid battery 28 are connected to each other and a cut-off state in which the motor generator and the battery are separated from each other; a node 32 which connects a first power supply line 29 connected to a positive electrode terminal of the lithium-ion battery 27, a second power supply line 30 connected to a positive electrode terminal of the lead-acid battery 28, and a charging line 31 connected to an output terminal of the motor generator 16 to each other; and a failure determination part 53b which executes failure determination processing for determining a failure of at least one of the opening/closing switch SW1 and the opening/closing switch SW2 on the basis of a control signal of the opening/closing switch SW1, a control signal of the opening/closing switch SW2, an electric current of the first power supply line 29 and an electric potential of the first power supply line 29.SELECTED DRAWING: Figure 2
【課題】車両用電源装置に設けられるスイッチの故障を判定する。【解決手段】モータジェネレータ16とリチウムイオンバッテリ27とを接続する導通状態と分離する遮断状態とに切り替えられる開閉スイッチSW1と、モータジェネレータ16と鉛バッテリ28とを接続する導通状態と分離する遮断状態とに切り替えられる開閉スイッチSW2と、リチウムイオンバッテリ27の正極端子に接続される第1電源ライン29と、鉛バッテリ28の正極端子に接続される第2電源ライン30と、モータジェネレータ16の出力端子に接続される充電ライン31と、を互いに接続するノード32と、開閉スイッチSW1の制御信号、開閉スイッチSW2の制御信号、第1電源ライン29の電流、および第1電源ライン29の電位に基づいて、開閉スイッチSW1と開閉スイッチSW2との少なくともいずれか一方の故障を判定する故障判定処理を実行する故障判定部53bと、を有する。【選択図】図2
