Abstract
A vehicle wiring system includes a plurality of functional units to be mounted in a vehicle, an optical transmission line that is wired between the functional units and configured to transmit an optical signal of the functional units, an electric wire harness that is provided, in a partial section of the optical transmission line, together with the optical transmission line in a state of being integrated with the optical transmission line, and an optical coupler that is disposed in a portion of the optical transmission line other than the section and constitutes a part of the optical transmission line.
Claims10
A vehicle wiring system comprising:
- a plurality of functional circuits to be mounted in a vehicle;
- an optical transmission line wired between the functional circuits and configured to transmit an optical signal of the functional circuits;
- an electric wire harness provided, in a partial section of the optical transmission line, together with the optical transmission line in a state of being integrated with the optical transmission line;
- and
- an optical coupler disposed in a portion of the optical transmission line other than the section and constituting a part of the optical transmission line.
An optical coupler configured to relay an optical signal between functional circuits to be mounted in a vehicle, the optical coupler comprising:
- a transparent body portion;
- and
- an optical waveguide formed in the body portion and branching in the body portion.
A method of constructing a vehicle wiring system, the method comprising:
- preparing a plurality of functional circuits to be mounted in a vehicle, an optical transmission line, an electric wire harness, and an optical coupler;
- wiring the optical transmission line between the functionalcircuits so as to transmit an optical signal of the functional circuits;
- wiring the electric wire harness in a partial section of the optical transmission line so that the electric wire harness is provided together with the optical transmission line in a state of being integrated with the optical transmission line;
- and
- disposing the optical coupler in a portion of the optical transmission line other than the section and causing the optical coupler to constitute a part of the optical transmission line.
