<P>PROBLEM TO BE SOLVED: To supply appropriate power to various vehicle electric loads even when consumption current of vehicle electric loads 45, 46, and 47 exceeds the maximum output current of a DC/DC converter 50. <P>SOLUTION: The power source control device of a vehicle includes a first power supply circuit for connecting first vehicle electric loads 45 and 46 to a power storage device 43 via a DC/DC converter 50, a second power supply circuit for connecting the first vehicle electric loads 45 and 46 to the power storage device 43 via a bypass switch 67 disposed in parallel to the DC/DC converter 50, and a third power supply circuit for connecting a second vehicle electric load 47 to the power storage device 43 via the DC/DC converter 50. When power is supplied to the first vehicle electric loads 45 and 46 by the second power supply circuit, the bypass switch 67 is set in an ON state by supplying power to the second vehicle electric load 47 by the third power supply circuit while actuating the DC/DC converter 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
