国内外汽车电磁兼容标准浅析

Analysis of Domestic and International Automotive Electromagnetic Compatibility Standards

近年来,汽车与新能源领域、通信领域的高速融合使得汽车行业正经历着一场重大变革。毫无疑问这场变革加快推进了汽车电动化、智能化、网联化的发展。搭载大量车载电气/电子部件和系统的车辆在运行期间会产生电气骚扰和射频骚扰,其频率范围宽且可以通过传导耦合的方式影响车载部件和系统,从而导致性能下降、功能降级,甚至是永久损坏。因此,本篇文章着重研究国内外汽车电子与电磁兼容领域的标准法规体系,以方便读者进一步了解汽车零部件和整车的电磁兼容标准内容。

In recent years,the rapid integration of automobiles,new energy fields,and communication fields has made the automotive industry undergo a major transformation.There is no doubt that this revolution has accelerated the development of electrification,intelligence,and networking of automobiles.Vehicles with a large number of on-board electrical/electronic components and systems generate electrical and RF disturbances during operation,with a wide frequency range that can affect on-board components and systems in a conductive coupling manner,resulting in performance degradation,functional degradation,and even permanent damage.Therefore,this article focuses on the research of standards and regulations in the field of automotive electronics and electromagnetic compatibility at home and abroad,so as to facilitate readers to further understand the electromagnetic compatibility regulations of auto parts and vehicles.
