To provide an auxiliary power unit that can switch a power supply quickly.SOLUTION: An auxiliary power unit 40 includes an auxiliary power supply 60, a power supply control unit 70, an analog judgment circuit 100, and a power supply switching circuit 110. The auxiliary power supply 60 is connected to a steering control device 30 through an auxiliary power supply side power supply path L2. The analog determination circuit 100 is provided separately from the power supply control unit 70. The analog determination circuit 100 determines an abnormality of a main power supply 50 by a power supply voltage signal Sv which is an analog signal, and generates a second control voltage signal SC2 indicating an abnormality of the main power supply 50 when an abnormality of the main power supply 50 is determined. The power switching circuit 110 switches the power supplied to the steering control device 30 to the auxiliary power 60 on the basis of the second control voltage signal SC2 indicating an abnormality of the main power supply 50.SELECTED DRAWING: Figure 2

    【課題】迅速に電源を切り替えることができる補助電源装置を提供する。【解決手段】補助電源装置40は、補助電源60と、電源制御部70と、アナログ判定回路100と、電源切替回路110とを備えている。補助電源60は、補助電源側給電経路L2を通じて操舵制御装置30と接続されている。アナログ判定回路100は、電源制御部70とは別に設けられている。アナログ判定回路100は、アナログ信号である電源電圧信号Svで主電源50の異常を判定するとともに、主電源50の異常を判定するときに主電源50の異常を示す第2制御電圧信号SC2を生成する。電源切替回路110は、主電源50の異常を示す第2制御電圧信号SC2に基づいて、操舵制御装置30に対して給電する電源を補助電源60に切り替える。【選択図】図2
