PROBLEM TO BE SOLVED: To provide a vehicular power supply control device capable of avoiding exhaustion of a battery and charging the battery.SOLUTION: A vehicular power supply control device comprises an IG relay 22 and an ACC relay 24 which connect an auxiliary battery 20 mounted on a vehicle 100 to an IG system electric load 21 and an ACC system electric load 23 or cut off the connection. The vehicular power supply control device comprises an ECU 10 which controls the IG relay and the ACC relay to cut off the connection of the auxiliary battery to the G system electric load and the ACC system electric load, in a preliminary preparation state before the vehicle shifts to a preparation state of being able to output driving force of an engine 101 and in a case that a voltage value of the auxiliary battery is below a first threshold, upon passage of a first limit time from when the auxiliary battery is connected to the IG system electric load and the ACC system electric load.SELECTED DRAWING: Figure 1

    【課題】バッテリ上がりを回避し、バッテリを充電することができる車両用電源制御装置を提供すること。【解決手段】車両100に搭載された補機バッテリ20とIG系電気負荷21やACC系電気負荷23との間を接続し、または該接続を遮断するIGリレー22やACCリレー24を備えた車両用電源制御装置であって、車両がエンジン101の駆動力を出力可能な準備状態に移行する前の前準備状態、かつ、補機バッテリの電圧値が第1の閾値未満である場合、補機バッテリとIG系電気負荷やACC系電気負荷が接続されてから第1の制限時間が経過したときに、補機バッテリとIG系電気負荷やACC系電気負荷との接続を遮断するようIGリレーやACCリレーを制御するECU10を備える。【選択図】図1
