To simplify a composition of a main line part and provide a vehicle circuit body to which a new electric wire is easy to add.SOLUTION: A vehicle circuit body includes: a communication main line (BB_LC) that is disposed in a vehicle body and has a power line having prescribed current capacity and a communication line having prescribed communication capacity; branch line sub-harnesses (LS(1) to LS(4)) that are each connected directly or indirectly to auxiliary devices (AE(1) to AE(4)); and a plurality of control boxes (CB(1) to CB(4)) which are distributed along the main line and each of which has a control unit for distributing, to branch lines connected to the main line, at least one of power from the power line to be supplied to the main line and signals from the communication line. The main line is formed from wiring material having at least one type of conductor from among flat conductors, rod conductors, and stranded wires. The communication line of the main line is disposed such that the plurality of control boxes are connected in a ring.SELECTED DRAWING: Figure 53
【課題】幹線部分の構成を簡素化し、新たな電線の追加も容易にできる車両用回路体を提供すること。【解決手段】車両用回路体は、所定の電流容量を有する電源ラインと、所定の通信容量を有する通信ラインとを有して車体に配索される通信用幹線(BB_LC)と、補機(AE(1)〜AE(4)に直接または間接的に接続される枝線サブハーネス(LS(1)〜LS(4)と、幹線に供給される電源ラインの電力及び通信ラインの信号のうち少なくとも一方を幹線に接続される枝線へ分配するための制御部を有し、幹線に沿って分散配置された複数の制御ボックス(CB(1)〜CB(4))と、を備える。幹線は、平型導体、丸棒導体及び撚り線のうち少なくとも一種類の導体を有する配索材で構成され、幹線の通信ラインは、複数の制御ボックスをリング状に接続するように配索される。【選択図】図53
