Research on Test Methods of Radiated Immunity Test for Intelligent Vehicles

分析智能车辆的主要敏感设备及工作频率特点;基于国际通行的汽车辐射抗扰测试标准,进行天线法和TLS系统法的电场分布理论分析和仿真分析,及电场分布和汽车影响的实际试验;针对国际辐射抗扰认证试验方法在智能车辆适应性方面的不足之处,提出改进方法。

This article analyzes the main sensitive equipment and working frequency characteristics of intelligent vehicle. In view of the internationally radiated immunity test standards of vehicles, the theoretical analysis and simulation analysis of the antenna method and the TLS method mentioned in the standards are carried out, also, the actual electric field distribution and vehicle influence tests are performed. According to the test results, the shortcomings of the international radiation immunity certification test in the adaptability of intelligent vehicles are put forward and the improved methods are proposed.
