The individual ECU (11a) controls power supply via the electric wire W. The microcomputer (21) of the individual ECU (11a) increases the average value of the wire current value of the current flowing through the wire W in stages. The microcomputer (21) determines whether or not there is an abnormality in the power supply via the wire (W) on the basis of the temperature difference between the wire temperature of the wire (W) and the ambient temperature around the wire (W) every time the average value of the wire current values is increased.

    单独ECU(11a)控制经由电线W的供电。单独ECU(11a)的微机(21)使经由电线W流过的电流的电线电流值的平均值阶段性地上升。微机(21)每当使电线电流值的平均值上升时,基于电线(W)的电线温度与电线(W)周边的环境温度的温度差判定经由电线(W)的供电是否发生异常。
