Wiring harness diagram wire path rapid calculation method

The invention relates to the technical field of automobile wire harnesses, and provides a wire harness diagram wire path rapid calculation method, which comprises the following steps of S1, detectingwire harness branches in a wire harness diagram, and putting identifiers of all the wire harness branches into an initial search list; S2, detecting whether at least two unmarked wire harness branchesexist in the initial search list or not, if yes, executing the step S3, and if not, outputting a wire path from each initial wire harness branch to a terminal wire harness branch; S3, selecting two unmarked wire harness branches as a starting wire harness branch and a terminating wire harness branch respectively, and taking the geometric center of the terminating wire harness branch as a target end point; and S4, calculating a wire path from the starting wire harness branch to the ending wire harness branch, identifying the wire harness branch in the wire path, and executing the step S2 at the same time.
