A vehicle circuit body is provided with: a backbone trunk line (BBLM) extending at least in the front-rear direction of a vehicle; a plurality of control boxes (CB) provided on the backbone trunk line; and a branch line (LS) that connects the control box and the accessory (AE). The backbone trunk line and the branch line (LS) are each provided with a power supply line (L1, L2B) having a predetermined current capacity and a communication line (Lx) having a predetermined communication capacity. The control box is provided with: a switching circuit (CBb), a bridge circuit (CBc), and a connection part (Cnx) serving as a branch line connection part connected to a branch line; and a microcomputer (CBa) that distributes power from the backbone main line to the branch lines by controlling the branch line connection unit in accordance with a control program. The control program can be changed from outside on the basis of the accessory connected to the branch line.
一种车辆电路体,配备有:骨干干线(BB_LM),其至少在车辆的前后方向上延伸;多个控制盒(CB),该多个控制盒设置在骨干干线上;以及支线(LS),该支线将控制盒与配件(AE)连接。骨干干线和支线(LS)均设置有具有预定电流容量的电源线(L1、L2B)和具有预定通信容量的通信线(Lx)。控制盒设置有:开关电路(CBb)、桥接电路(CBc)和连接部(Cnx),其用作连接到支线的支线连接部;以及微计算机(CBa),其通过根据控制程序控制支线连接部而将来自骨干干线的电力分配到支线。所述控制程序能够基于连接到支线的配件而从外部进行改变。
