摘　　要：随着汽车电子技术的不断发展,汽车上电子零部件的数量和功能日益增多,整车零部件之间的通讯线也是呈几何级增长,各零部件信号线上的瞬态干扰和耦合干扰也显得越发敏感。然而,如何利用现有资源更准确地模拟实车上可能出现的干扰情况并进行前期测试,已成为各实验室的重要工作之一。本文结合信号线干扰耦合验证实例,分析了干扰波形耦合的情况,为零件研发、检测、测试计划定义和标准制定提供参考。With the increasing electronization rate of automobiles,the number and function of electronic parts on automobiles are also increasing,and the signal lines on the whole vehicle are also geometric growth,so the transient interference and coupling interference on the signal lines have become more and more sensitive.However,how to use available resources to more accurately simulate the possible interference on the real vehicle for preliminary testing has become one of the important work of all laboratories.In this paper,cases of waveform coupling are analyzed based on some examples of signal line interference coupling verification,which can provide reference for parts development,testing and standard formulation.
