<P>PROBLEM TO BE SOLVED: To provide a power supply control apparatus capable of starting a vehicle as required though the heat of an inrush limit resistor is dissipated certainly. <P>SOLUTION: An ECU 10 for the power supply control apparatus 2 includes an on-normal relay controller 13. The on-normal relay controller 13 controls a ground relay 7 and a pre-charge relay 8 so as to turn them on, and controls a main relay 6 and the pre-charge relay 8 so as to turn the main relay 6 on and the pre-charge relay 8 off when receiving a start-indicating signal from a key switch 15. The on-normal relay controller 13 decides whether a specified time passes after the on timing of the main relay 6 when receiving a stop-indication signal from the key switch 15. The on-normal relay controller 13 maintains the main relay 6 and the ground relay 7 under an on-state when the specified time does not pass, and controls the main relay 6 and the ground relay 7 so as to turn them off when the specified time passes. <P>COPYRIGHT: (C)2011,JPO&INPIT |
