PROBLEM TO BE SOLVED: To provide a vehicle power system capable of downsizing ECUs (Electronic Control Units).SOLUTION: The vehicle power system includes a switching power supply 4 generating an operation power supply for operating a plurality of ECUs 6-8 by decreasing a power supply supplied from at least one of a generator 1 and a battery 2, and a power supply distributor 5 distributing the operation power supply generated from the switching power supply 4 to the plurality of ECUs 6-8. By forming power supply circuits of the ECUs 6-8 into one power supply circuit, each power circuit from each ECU can be omitted and thus each ECU can be downsized. |
