The Analysis of Automotive Wiring Harness Dynamic Crosstalk

Abstract:

Since the installation and strapping of the harness, and the vehicle motion state of the automotive is different. The crosstalk automotive wire harness is not a fixed value, but a certain dynamic range in the actual situation. Through the analysis of the factors of influence cable crosstalk can draw a conclusion that the cable relative position and disturbed line termination impedance is a major factor in the production of dynamic change. We analyze the dynamic range of crosstalk of 14 core wire harness model by using a statistical method, as a result of the change of the relative position of cable far-end crosstalk (FEXT) range within 1 dB, but when the disturbed line termination impedance changes from 50Ω to 1000Ω, the cable far-end crosstalk range reached 15 dB. It provides reference basis for the automotive wiring harness electromagnetic compatibility design.
