The invention relates to a management method for compatible multi-system vehicle to X V2X, which comprises the following steps: receiving vehicle state information of an installed vehicle and receiving vehicle location information of the installed vehicle; generating vehicle driving information according to the vehicle state information and the vehicle location information; receiving surrounding vehicle data sent by V2X terminals on other vehicles and decoding the same, wherein the surrounding vehicle data is transmitted based on any at least two of WAVE, ETSI-ITS and/or LTE-V standards, and decoding the surrounding vehicle data and converting the same into a first standard format after the surrounding vehicle data is received according to the corresponding technology, and reminding a driver or controlling the vehicle according to the vehicle driving information and the surrounding vehicle data in the first standard format. The management method for compatible multi-system vehicle to XV2X in the present invention can support a plurality of known V2X standards, thereby expanding the available range and facilitating compatibility in regions where different standards are used.
