RI Testing of the OBU: Electronic Components and Vehicle-Level

V2X communication technology is increasingly being utilized to enhance the driving stability of passengers and to advance autonomous driving technology. To utilize V2X communication technology, a vehicle requires a V2X communication device called an On-Board Unit (OBU). If the OBU malfunctions due to external electromagnetic interference while driving, it can lead to traffic accidents. Therefore, Radiated Immunity (RI) verification for electromagnetic interference is essential. In this paper, we configured an electromagnetic interference and V2X communication environment in an Absorber-Lined Shielded Enclosure (ALSE) chamber and conducted RI tests on both the electronic components and vehicle level of the OBU.
