Patent ID: 7546407

Claim:
A flexible wiring system for an electronic system that includes inputting devices and outputting devices that are located at various areas of the vehicle, said flexible wiring system comprising: a basic control unit having a plurality of input side connectors for respectively receiving signals of said inputting devices, an outputting-device control circuit for controlling one of said outputting devices according to at least one of said signals of said inputting devices and a first changeover circuit disposed between said input side connectors, and said outputting-device control circuit and a plurality of output side connectors; an intermediate distributing unit, provided separately from the basic control unit, including a plurality of first side connectors respectively connected with said input side connectors of said basic control unit and output side connectors of said basic control unit, a plurality of second side connectors and a changeover mechanism disposed between a first set of said first side connectors and a first set of said second side connectors; a plurality of wire harnesses having a plurality of electric wires, each of said wire harnesses having one end connected with one of said second side connectors and the other end connected with at least one of the inputting devices and outputting devices located at an area different from other areas where other inputting devices and outputting devices are located; and changeover control means for controlling said changeover mechanism and said change over circuit of said base control unit to change connection of said first set of first side connectors with said first set of second side connectors and connection of said first set of first side connectors with said input side connectors of said base control unit so as to switch connection of said first set of second side connectors with the outputting-device control circuit from one of said input side connectors to another according to a specific signal relating to said extra electric device to be connected by one of said wire harnesses with one of said first set of said second side connectors.
