To allow an auxiliary power source to supply power to on-vehicle loads while suppressing consumption power when defect occurs in a main power source when a vehicle is not started.SOLUTION: In an on-vehicle power source control device 10, a power source driving circuit 24, when a driving signal generating part 17 generates an off-signal and when detecting a defect state of a main power source 11, controls a power source circuit 23 so that power is supplied from an auxiliary power source 12 to a control part 25. The control part 25, when the driving signal generating part 17 generates the off-signal and when detecting the defect state of the main power source 11, uses power supplied from the auxiliary power source 12, controls a relay 21 so that the state is switched to a first stoppage state and controls a converter 22 so that the state is switched into a second authorized state.SELECTED DRAWING: Figure 1
【課題】車両が始動していないときに主電源の失陥が生じた場合に、消費電力を抑制しつつ補助電源から車載用負荷に電力を供給する。【解決手段】車載用の電源制御装置10において、電源駆動回路24は、駆動信号生成部17がオフ信号を生成しており、且つ主電源11の失陥状態が検出された場合に、補助電源12から制御部25に電力が供給されるように電源回路23を制御する。制御部25は、駆動信号生成部17がオフ信号を生成しており、且つ主電源11の失陥状態が検出された場合に、補助電源12から供給される電力を用いて、リレー21を制御して第1停止状態に切り替え、コンバータ22を制御して第2許可状態に切り替える。【選択図】図1
