In the present invention, partition ECUs (10A) are respectively provided in a plurality of regions (A1-A4) divided on a vehicle, and each of the partition ECUs (10A) controls a first device (20) provided in the same region. Independent ECUs (11, 12) are provided, and each independent ECU (11, 12) controls the second device of the functional group (G1, G2) independently of the control of the partition ECU, regardless of the division of the area. A central ECU (30) that manages a subarea ECU (10A) and independent ECUs (11, 12) for each area is provided. Power supply inputs of the in-vehicle power supply (35), the partition ECU (10A), and the central ECU (30) are connected via first power supply connection paths (41, 42), and power supply inputs of the in-vehicle power supply (35) and the independent ECUs (11, 12) are connected via second power supply connection paths (46, 47). The power of the second device is provided by the independent ECU.
在本发明中,分区ECU(10A)分别设置在车辆上划分的多个区域(A1‑A4)中,并且每个分区ECU(10A)控制设置在相同区域中的第一设备(20)。设置独立ECU(11、12),并且每个独立ECU(11、12)独立于分区ECU的控制来控制功能组(G1、G2)的第二设备,而与区域的划分无关。设置有管理每个区域的分区ECU(10A)和独立ECU(11、12)的中央ECU(30)。车载电源(35)、分区ECU(10A)和中央ECU(30)的电源输入通过第一电源连接路径(41、42)连接,车载电源(35)和独立ECU(11、12)的电源输入通过第二电源连接路径(46、47)连接。第二设备的电源由独立ECU提供。
