Abstract

It is possible to optimize the time required for a success/failure determination step and the accuracy of the success/failure determination step by determining region-based connector/wiring information to be created and increasing or decreasing the number of patterns of the region-based connector/wiring information. When a wire harness is arranged in each partitioned area of a vehicle space, specifications satisfied by the vehicle are referenced, region-based connector/wiring information described for a wire harness arranged in each partitioned area realizing a predetermined specification is created, and the presence/absence of errors in connections of electric wires is inspected for the created region-based connector/wiring information.

Claims

1. A wire harness conductivity inspection method comprising:

a reference step of referencing specifications satisfied by a vehicle in which a wire harness is arranged in each partitioned area of a plurality of partitioned areas of a vehicle space, wherein the specifications respectively indicate different systems of the vehicle; and

a creation step of creating, for each partitioned area, region-based connector/wiring information described for a wire harness arranged in the partitioned area, wherein the region-based connector/wiring information includes specifications of the different systems in the partitioned area; and

an inspection step of inspecting presence/absence of an error in a connection of electric wires in the created region-based connector/wiring information;

wherein the region-based connector/wiring information of each partitioned area of the plurality of partitioned areas includes at least one common specification indicating at least one common system, and

wherein the above steps are carried out by a processing unit.

2. A wire harness conductivity inspection program which, when executed by a computer, causes the computer to execute the steps of the wire harness conductivity inspection method according to claim 1.

3. The wire harness conductivity inspection method according to claim 1, wherein the inspection step is not performed for a partitioned area with the least number of specifications indicating systems.

4. A wire harness conductivity inspection method comprising:

a first specification step of specifying a predetermined first partitioned area from among partitioned areas into which a vehicle space is partitioned; and

a creation step of creating region-based connector/wiring information described for at least a predetermined wire harness from among first wire harnesses arrangeable in the first partitioned area, wherein the region-based connector/wiring information includes specifications of different systems in the first partitioned area;

wherein the above steps are carried out by a processing unit.

5. The wire harness conductivity inspection method according to claim 4, wherein the predetermined first partitioned area contains the greatest number of the specifications indicating systems from among the partitioned areas.

6. The wire harness conductivity inspection method according to claim 4, further comprising a second specification step of specifying a predetermined second partitioned area from among partitioned areas into which a vehicle space is partitioned, wherein the predetermined second partitioned area contains the second greatest number of the specifications of systems from among the partitioned areas;

and

a second creation step of creating region-based connector/wiring information described for at least a predetermined wire harness from among second wire harnesses arrangeable in the second partitioned area, wherein the region-based connector/wiring information includes specifications of different systems in the second partitioned area;

wherein the region-based connector/wiring information of each of the first partitioned area and the second partitioned area includes at least one common specification indicating at least one common system.

7. The wire harness conductivity inspection method according to claim 4, further comprising a final specification step of specifying a predetermined final partitioned area from among partitioned areas into which a vehicle space is partitioned, wherein the final specification step further indicates that the predetermined final partitioned area contains the least number of specifications of systems from among the partitioned areas, the region-based connector/wiring information of the final partitioned area includes at least one common specification indicating at least one common system;

a creation step of creating region-based connector/wiring information described for at least a predetermined wire harness from among final wire harnesses arrangeable in the final partitioned area, wherein the region-based connector/wiring information includes specifications of different systems in the final partitioned area; and

an inspection step of inspecting the presence/absence of an error in a connection of electric wires in the first and second partitioned areas while not inspecting the presence/absence of an error in a connection of electric wires in the final partitioned area.
