摘要
传统汽车电磁防护主要依赖大型金属壳体或屏蔽方舱,虽能保障设备基本运行,但普遍存在空间利用率低、制造成本高昂的问题。针对上述痛点,提出并验证了一种面向汽车电气系统的综合电磁防护方法。该方法聚焦电磁干扰传导的三大核心物理路径——线束、控制器模块及接地点,通过实施线束屏蔽处理、控制器模块防护处理与电气系统接地点阻抗控制,系统性地提升电磁兼容性(EMC)与抗电磁毁伤能力。试验表明,该方法在保障防护效能的同时,显著降低了空间占用与实施成本,为汽车电气系统尤其是特种车辆与新能源汽车的电磁防护设计提供了有效解决方案。
Conventional automotive electromagnetic protection relies heavily on bulky metal enclosures or shielded cabins.Whileeffective in meeting basic operational requirements,these approaches suffer from significant space inefficiency and high manufacturingcosts.Addressing these limitations,this paper proposes and validates a comprehensive electromagnetic protection method targeting theautomotive electrical system.This method focuses on the three core physical pathways for electromagnetic interference(EMI)conduction:wiring harnesses,controller modules,and grounding points.It incorporates harness shielding treatment,controller module protection treatment,and impedance control of electrical system grounding points to systematically enhance electromagnetic compatibility(EMC)and resistance to electromagnetic damage.Experimental results demonstrate that this approach ensures protection efficacy whilesignificantly reducing spatial footprint and implementation costs,offering an effective solution for the electromagnetic protection designof automotive electrical systems,particularly for special-purpose vehicles and new energy vehicles.
