A zone ECU is disposed in each of a plurality of regions partitioned on a vehicle, and each zone ECU controls a first device disposed in the same region. Independent ECUs are disposed, and each of the independent ECUs controls a second device of a function group independent of the control performed by the zone ECU without relation to the partition of the regions. A central ECU for managing the zone ECU in each of the regions and the independent ECUs is disposed. An onboard power supply is connected to power supply inputs of the zone ECUs and the central ECU Via a first power supply connection path, and the onboard power supply is connected to power supply inputs of the independent ECUs via a second power supply connection path. Power supply electric power to the second device is supplied from the independent ECUs.
