To provide a power supply control device, an in-vehicle control device, and a power supply control method that can detect abnormalities in power supply when a current value is small.SOLUTION: An individual ECU 11a controls the power supply via an electric wire W. A microcomputer 21 of the individual ECU 11a gradually increases the average value of the electric wire current values of the current flowing through the electric wire W. Each time the microcomputer 21 raises the average value of the electric wire current value, the microcomputer determines whether an abnormality has occurred in the power supply via the electric wire W on the basis of the temperature difference between the electric wire temperature of the electric wire W and the environmental temperature around the electric wire W.SELECTED DRAWING: Figure 2
【課題】電流値が小さい状態で給電の異常を検知することができる給電制御装置、車載制御装置及び給電制御方法を提供する。【解決手段】個別ECU11aは電線Wを介した給電を制御する。個別ECU11aのマイコン21は、電線Wを介して流れる電流の電線電流値の平均値を段階的に上昇させる。マイコン21は、電線電流値の平均値を上昇させる都度、電線Wの電線温度と、電線W周辺の環境温度との温度差に基づいて、電線Wを介した給電に異常が発生しているか否かを判定する。【選択図】図2
