To enable the reduction of the workload in designing or manufacturing a wire harness in response to changes in the specifications or types of various auxiliary machines mounted on vehicles.SOLUTION: Each constituent included in the whole circuit of a vehicular wire harness is classified into three layers of an upstream circuit, an independent domain circuit, and a zone circuit. This method has a procedure for deciding the constitution of a first sub harness WH1 belonging to the upstream circuit, a procedure for deciding the constitution of the second sub harness WH2 belonging to the independent domain circuit, a procedure for deciding the constitution of a third sub harness WH3 belonging to the zone circuit, and a procedure for integrating the sub harness, the second sub harness, and the third sub harness. The examination for optimizing a design change of a wire harness or a production method of a wire harness in response to a specification change on the vehicle side becomes easy. Each sub harness can be produced by separate factories.SELECTED DRAWING: Figure 1
【課題】車両に搭載される様々な補機の仕様変更や種類の変更に対してワイヤハーネスの設計作業や製造作業の負担を軽減する可能にすること。【解決手段】車両用ワイヤハーネスの回路全体に含まれる各構成要素をカテゴリの違いに応じて上流回路、独立ドメイン回路、及びゾーン回路の3層に層別する。前記上流回路に属する第1サブハーネスWH1の構成を決定する手順と、前記独立ドメイン回路に属する第2サブハーネスWH2の構成を決定する手順と、前記ゾーン回路に属する第3サブハーネスWH3の構成を決定する手順と、前記第1サブハーネス、前記第2サブハーネス、及び前記第3サブハーネスを統合する手順とを有する。車両側の仕様変更に対するワイヤハーネスの設計変更や、ワイヤハーネスの生産方法を最適化するための検討が容易になる。各サブハーネスを別々の工場で生産できる。【選択図】図1
