摘　　要：大部分新申请公告的车型选择安装不停车收费系统车载电子单元(ETC OBU),GB/T 38444-2019中只提到ETC OBU的电磁兼容性测试要求,并未指定满足具体要求的操作方法。为提高测试结果的一致性,基于GB/T 38444-2019的主要技术内容,提出了不停车收费系统路侧单元(ETC RSU)发射功率及环境底噪的确认及测试结果判定方法,为ETC OBU的电磁兼容实际测试与认证提供指导。Most car manufacturers choose to install electronic toll collection on board unit(ETC OBU)for their upcoming models,GB/T 38444-2019 only mentions the EMC test requirements of ETC OBU,but does not specify the methods to meet the specific requirements.In order to improve the consistency of test results,based on the main technical content of GB/T 38444-2019,methods to confirm the electronic toll collection roadside unit(ETC RSU)transmitting power and environmental noise and to evaluate the test results are put forward,which provides guidance for the actual EMC test and certification of ETC OBU.
