If there is no reliability, high-performance electronic devices indicator is no meaning. Reliability design, testing and verification methods of the vehicle electronic equipment are analyzed in this paper, and presented in the industry designed to improve the reliability of electronic equipment ideas, to regulate the reliability of electronic equipment designed to provide a technical basis.

In allusion to the current existing problems of automotive wire-harness design, which are no interaction between 2D design and 3D design, and disconnect between design level and simulation level, the advanced design methods are needed. In this paper, it puts forward a kind of automotive wire-harness design method based on CHS and PRO/E software. Then it details its design steps including schematic / layout / harness design, 3D interaction, data management, etc. Finally, it summarizes the advantages of this advanced design method.
