Abstract
This vehicle circuit routing system as a whole has a backbone-like routing structure, said system being provided with a plurality of backbone JB structures, wherein the vehicle circuit bodies of the backbone JB structures are connected to each other by means of a backbone main line. Each vehicle circuit body is provided with a power supply circuit that is connected to a main power supply on the vehicle, a plurality of connection parts to which a plurality of branch lines having a power supply line are connected, and a control unit that controls the distribution of power from the power supply circuit to the branch lines.
Claims6
A circuit for a vehicle, that is placed on the vehicle, the circuit including:
- a power supply circuit that is connected to a main power supply on the vehicle;
- a plurality of connection portions to which a plurality of branch lines, having power supply lines and communication lines, are connected respectively;
- and
- a control portion that controls distribution of power from the power supply circuit to the plurality of branch lines,
- wherein each of the branch lines comprises one of a plurality of wire harnesses each having at least one of the power supply lines and at least one of the communication lines respectively therein,
- wherein the control portion and the plurality of connection portions are arranged on a circuit board,
- wherein the wire harnesses are arranged as directly connecting to respective ones of the connection portions and as adjacent to each other along a length of the circuit board and at a first side of the circuit board, and
- wherein the power supply circuit is formed on the circuit board.
