PROBLEM TO BE SOLVED: To provide a vehicular circuit body which simplifies a structure for electrically connecting various pieces of electric equipment with a power source on a vehicle and pieces of electric equipment with one another and is capable of down-sizing and reducing weight.SOLUTION: Various kinds of auxiliary machines 71, 72, 73 are connected to branch lines branched respectively from trunk lines included in backbone structures 20, 30, 40 of the respective parts to secure power supply or communication paths. The control of power distribution is realized by communication between higher-order control parts 11-13 arranged in smart power source boxes 10 and lower-order control parts 51c, 52c, 53c arranged in area drivers 51-54. A switching circuit is arranged at a connection point between a trunk line and a branch line to perform automatic switching so that connected terminals may align with each other. Specifications of current of many terminals on the power supply side are fixed to be common, the number of terminals to be used is switched to control power to be distributed. Making components common or reducing article numbers are facilitated. Connection positions can freely be changed.SELECTED DRAWING: Figure 1

    【課題】様々な電装品と車両上の電源との間および電装品同士の電気接続のための構造を簡素化すると共に、小型化及び重量の低減が可能な車両用回路体を提供する【解決手段】各部のバックボーン構造体20、30、40に含まれる幹線からそれぞれ分岐した分岐線に各種補機71、72、73を接続して電力の供給や通信経路の確保を行う。スマート電源ボックス10等に配置される上位制御部11〜13とエリアドライバ51〜54等に配置される下位制御部51c、52c、53cとの間で通信して電力分配等の制御を実現する。幹線と分岐線との接続箇所に切替回路を配置して、接続する端子同士が整合するように自動的に切り替える。電力供給側の多数の端子の電流等の仕様を共通に固定し、使用する端子数を切り替えて分配する電力を制御する。部品の共通化や品番の削減が容易になる。接続位置を自由に変更できる。【選択図】図1
