A vehicle-to-everything (V2X) abnormal behavior detection method applied to a vehicle communications system that includes a V2X sending terminal, a V2X receiving terminal, and a V2X server. The method includes that the V2X receiving terminal receives a V2X message from the V2X sending terminal. The V2X receiving terminal determines, according to an abnormal behavior detection policy, that the V2X message is an abnormal message. The V2X receiving terminal sends a report message including the V2X message to the V2X server.
