1. A vehicle communication method performed by one or more processors of an electronic toll collection (ETC) system, wherein the ETC system comprises an ETC roadside unit (RSU), a loop detector arranged at a preset distance from the ETC RSU, and an ETC onboard unit (OBU), wherein each of the ETC RSU and the ETC OBU has a processor, a memory and computer-readable instructions stored in the corresponding memory that are configured to be executed by the corresponding processor to perform the vehicle communication method collectively, and the method comprising:
triggering, by the one or more processors, when the loop detector determines that a distance between an ETC OBU on a first vehicle and the ETC RSU is within the preset distance, the ETC RSU to perform ETC OBU detection on the ETC OBU on the first vehicle, the preset distance being greater than or equal to a communication radius of the ETC RSU;
establishing, by the one or more processors, when the ETC OBU on the first vehicle is detected, a connection between the ETC OBU on the first vehicle and the ETC RSU;
performing, by the one or more processors, ETC billing on the first vehicle through the ETC RSU after the ETC RSU establishes the connection with the ETC OBU on the first vehicle;
estimating, by the one or more processors, time for the ETC RSU to perform billing on a second vehicle after the ETC RSU performs the ETC billing on the first vehicle, to determine a duration for which the ETC RSU and the ETC OBU on the first vehicle are capable of performing vehicle communication message interaction based on a speed of the first vehicle and an effective communication range of the ETC RSU; and
performing, by the one or more processors, after the ETC RSU performs the ETC billing on the first vehicle, vehicle-to-everything (V2X) communication message interaction with the ETC OBU on the first vehicle through the ETC RSU via the connection with the ETC OBU from a remote device within the duration when the ETC OBU is still within the effective communication range of the ETC RSU.
