To provide a vehicular power source control device capable of effectively charging a plurality of power sources by controlling the power supply from a power supply means to the power sources by determining the charging priority order of the power sources based on at least one of the service state of the power sources to be detected for each control unit and the power consumption state of an electronic unit.
In a system in which a control unit is constituted of at least one electronic unit out of a plurality of electronic units mounted to a vehicle, and power sources B1-B13 for supplying power to the electronic unit in the control unit are provided on each control unit, the charging priority order of the power sources is determined based on at least one of the service state of the power source to be detected for each control unit and the power consumption state of the electronic units, and the supply of the power generated by an alternator 2 to the plurality of power sources B1-B13 is controlled based on the determined charging priority order.
