Crosstalk of automotive wiring harness wires. The main purpose is to study the electromagnetic interference caused by near-field coupling between adjacent wires of automobile wiring harness. To a certain extent, it will also affect the electromagnetic radiation and electromagnetic radiation sensitivity of automobile wiring harness wires and electrical and electronic equipment. For example, crosstalk between two wires connected to a certain device in a car wiring harness generates an induction signal on the victim wire. The induction signal then generates electromagnetic radiation through the victim wire, which may cause the device to fail to meet the radiation emission requirements. Restrictions. If the disturbed wire is the power cord of the device, it may cause the device to fail to meet the conducted emission limit. At the same time, the crosstalk generated between wires connected to the same device may also increase the electromagnetic radiation sensitivity of the device [93]. Therefore, the research on the crosstalk of automotive wiring harnesses is of great significance. This article will also focus on the related issues of automotive wiring harness crosstalk in the following chapters.
The research on crosstalk of automobile wiring harness mainly involves the extraction of distributed parameters, time-domain transient response analysis, frequency-domain steady-state analysis, etc. At the same time, due to the reality of automobile wiring harness wiring and installation methods, as well as the objective conditions of the car when driving , Will cause the position of the wire harness of the car to change randomly, which will lead to the change of the distribution parameters of the car wire harness, and the actual crosstalk of the car wire harness will show a certain degree of uncertainty. Therefore, predicting the distribution parameters of automotive wiring harnesses and the statistical characteristics of wire crosstalk has also become a new direction of electromagnetic compatibility research on automotive wiring harnesses.
