PROBLEM TO BE SOLVED: To control a power supply voltage supplied to a lamp and the like of a vehicle, the lamp and the like used while an engine is stopped regardless of the residual charge amount of a battery, thus saving power consumption even in the case of the residual charge amount of the battery being sufficient, and saving power consumption in the case of using the battery for a long time.SOLUTION: A vehicular power supply control apparatus 100 for use in controlling a power supply to a light and the like from a power supply section that includes batteries 102, 103 and a generator 101, in a vehicle, includes: a control part 108 for determining whether an engine of the vehicle is operated or stopped; and a voltage control part for stepping down a voltage supplied to a vehicular hazard lamp 107 to a voltage lower than output voltages of the batteries 102, 103, in a case where the engine is determined to be stopped.SELECTED DRAWING: Figure 1

    【課題】バッテリの残量に関わらずエンジンの停止中に使用する車両の灯火類に供給する電源電圧を制御することにより、バッテリの残量が十分である場合であっても省電力にすると共に、バッテリを長時間使用する場合に省電力にすること。【解決手段】車両においてバッテリ102、103と発電機101とを含む電源部から灯火類への電源供給を制御する車両用電源供給制御装置100は、車両のエンジンが動作中か停止中かを判定する制御部108と、エンジンが停止中であると判定された場合に、車両のハザードランプ107への供給電圧を、バッテリ102、バッテリ103の出力電圧よりも低い電圧に降圧する電圧制御部と、を有する。【選択図】図1
