PROBLEM TO BE SOLVED: To provide a vehicle power source control device capable of supplying power to electric power loads requested to be operated even when the state of a vehicle is changed.SOLUTION: The state of a vehicle and the state of the surrounding of the vehicle are detected on the basis of signals acquired from a signal line S1 transmitting signals from individual power feeding switches individually operating power loads included in each load group A, B, and C and various sensors and a signal line S2 connecting ECUs such as an engine ECU 3a and a vehicle outside communication ECU 3b to each other. Each of output voltage of DC/DC converters 42a, 42b and 42c is set so as to supply voltage stored in each of a ROM 412 or a RAM 413 to each load group A, B, and C in accordance with both of the detected states. |
