摘要
随着电动汽车零部件所处的车内、外电磁环境日趋复杂,车载部件的电磁干扰问题备受关注。结合实车电磁干扰案例,对无钥匙进入及启动系统与真空助力系统的受干扰机理、优化措施进行了重点论述。案例表明:电动汽车后期加装行车记录仪可能给PEPS系统带来同频干扰;高功率短波电台通过"无意"天线也可以造成车载真空泵控制器异常使能甚至损坏。
With the increasing complexity of electromagnetic environment inside and outside of the electric vehicle,the electromagnetic sensitivity(EMS)of on-board electrical components has attracted tremendous attention.Combined with the electromagnetic interference cases,the interference mechanism and optimization measures of PEPS(Passive Entry and Passive Start) and vacuum pump system were discussed.The cases show the later stage installation of automobile?data?recorder may bring same-frequency interference to the PEPS system.Meanwhile the high-power short-wave radio may also cause the vehicle vacuum pump controller abnormal enabling or even damage through the "unintentional antenna".
