Research on Vehicle Radiation Immunity Test Method Based on Actual Electromagnetic Environment

In order to assess the radiation immunity performance of the vehicles in the actual electromagnetic environment, the radiation immunity test method based on the actual electromagnetic environment is studied. The test methods are analyzed from the aspects of electromagnetic environment acquisition and playback, field strength calibration, vehicle state setting and performance evaluation methods. The vehicle adaptability tests to actual electromagnetic environment are also carried out in actual location and in the 10m semi-anechoic chamber. The test results show that the vehicle malfunctions in the actual location can be effectively reproduced when tested in the 10m semi-anechoic chamber and the feasibility of the actual electromagnetic environment radiation immunity test method is preliminarily verified, which is of great significance for the enterprises to comprehensively evaluate the electromagnetic compatibility performance of the vehicles.
