With the continuous development of automobile electronic technology, in order to meet the needs of modern automobiles in terms of safety, comfort, intelligence, energy saving, and environmental protection, more and more electrical and electronic products are widely used in automobiles, which makes the electromagnetic compatibility of automobiles Performance faces severe challenges. Therefore, automotive electromagnetic compatibility technology has become a research hotspot of major automakers and scientific research institutions at home and abroad. As the main body of the automotive electronic network, automobile wiring harnesses connect different electrical and electronic equipment in the automobile. The types and numbers of wires are also rapidly increasing with the wide application of automobile electrical and electronic equipment. For the electromagnetic compatibility research of automobile wiring harness, it can usually be divided into three aspects: automobile wiring harness wire crosstalk, electromagnetic radiation and electromagnetic radiation sensitivity. Among them, automobile wiring harness wire crosstalk can not only cause errors or loss of data transmitted on the wire, and false triggering of functional equipment, but also may have a certain impact on the electromagnetic radiation and electromagnetic radiation sensitivity of automobile electrical and electronic equipment. Therefore, it is aimed at automobile wiring harness wires. The study of crosstalk is of great significance. It can provide a strong theoretical basis for solving the electromagnetic compatibility problem of automotive wiring harnesses. In the early stage of automobile design, electromagnetic compatibility problems should be avoided as much as possible, so as to shorten the automobile research and development cycle and reduce automobile research and development costs. purpose. This article is funded by the special scientific research fund for doctoral disciplines of universities and colleges “Research on Electromagnetic Compatibility Modeling of Vehicles Based on Stochastic Statistics Technology” (No.20110061110059), focusing on the analysis and prediction methods of crosstalk related problems of automotive wiring harnesses. The research includes accurate extraction of automobile wiring harness distribution parameters, time-domain transient analysis and frequency-domain steady-state analysis of automobile wiring harness wire crosstalk, as well as forecasting of automobile wire harness distribution parameters and statistical characteristics of wire crosstalk.
