With the development of the autonomous driving techniques, basic assisted driving functions are evolving to higher level full-autonomous driving. These high level autonomous driving functions are bonded to complicated on-board electronic components and systems which could be vulnerable to EM-environment, leading to malfunction even lethal accident. This paper studies the possibility of electromagnetic immunity test for high level autonomous driving functions. Radiated immunity test inside anechoic chamber and out door BCI injection immunity test are proposed. The combination of these two methods can obtain a relatively complete electromagnetic safety evaluation of autonomous driving

The increasing complexity of the electromagnetic environment poses a threat to the reliability of intelligent connected vehicles. Carrying out performance verification of intelligent connected vehicles in different electromagnetic scenes plays an important role in ensuring the safety of vehicles. A method for constructing electromagnetic scenes in the 10m semi-anechoic chamber is presented in the paper. By constructing the electromagnetic environment collection system, the main technical indicators of the electromagnetic environment collection related to the intelligent connected vehicles are analyzed, and the construction scheme of the electromagnetic environment scene library is studied. Based on the electromagnetic environment simulation system, the effectiveness of the electromagnetic scene reproduction is verified from the two aspects of test result comparison and signal comparison, which provides support for the test and verification of the electromagnetic compatibility performance of the intelligent connected vehicles in the laboratory.
