To provide a power supply monitor device and a control system that can prevent the driving of a vehicle from being affected in a case of occurrence of ground fault abnormality.SOLUTION: In a control system 100 that comprises a first control device 41 and a second control device 42 capable of controlling an electric load 32, and supplies electric power from a first power supply 10 to the first control device through a first line LA1 and electric power from a second power supply 16 to the second control device through a second line LA2, a power supply monitor device 20 comprises: a connection line LB which connects the first line and second line; an inter-line switch SW; a current limiting element 23 which allows electrification from a first line side to a second line side in a current-limited state and also blocks electrification from the second line side to the first line side; a monitor part 21 which monitors a voltage drop on the first line with the inter-line switch closed; and a switch operation part 22 which releases the inter-line switch when it is determined that a voltage drop is caused during drive supporting.SELECTED DRAWING: Figure 1

    【課題】地絡異常の発生時において車両の運転に影響が及ぶことを抑制できる電源監視装置及び制御システムを提供する。【解決手段】電気負荷32の制御を可能とする第1制御装置41及び第2制御装置42を備え、第1電源10から第1経路LA1を介して第1制御装置に電力を供給し、第2電源16から第2経路LA2を介して第2制御装置に対して電力を供給する制御システム100において、電源監視装置20は、第1経路と第2経路とを接続する接続経路LBと、経路間スイッチSWと、第1経路側から第2経路側への通電を電流制限した状態で許容するとともに、第2経路側から第1経路側への通電を阻止する電流制限素子23と、経路間スイッチを閉鎖した状態で、第1経路での電圧低下を監視する監視部21と、運転支援中に電圧低下が生じたと判定された場合に、経路間スイッチを開放するスイッチ操作部22と、を備える。【選択図】図1
