Electric Property Analysis and Wire Placement Optimization of Automotive Wire Harness

This paper describes an analysis and optimization technique for understanding and effective design of an automotive wire harness. In the analysis phase, the multiple linear regression analysis is used to reveal the relationship between an electric property of the wire harness and its cross-sectional shape. Subsequently, we perform coarse and fine optimization processes with the knowledge obtained in the prior analysis phase to efficiently determine the optimal placements of the wires so that a crosstalk voltage is reduced. The proposed technique and knowledge obtained from results will contribute the future automotive EMC/SIPI design.
