Description

Vehicle cloud protocol matching method and related equipment Technical Field The present application relates to the field of communications technologies, and in particular, to a vehicle cloud protocol matching method and related devices. Background In the field of Internet of vehicles, data interaction between a vehicle networking terminal (T-Box) and an Internet of vehicles service platform (TSP) through a private protocol is a basis for realizing functions such as remote control and state inquiry. Along with the rapid iteration of the vehicle model and the normalization of the over-the-air (OTA) upgrade of the software, the software version actually operated by the vehicle end and the corresponding cloud private protocol version thereof are increasingly fragmented. The prior art generally requires that the TSP platform communicate with all vehicles using a unified set of proprietary protocols compatible with historical multiple versions, or mandates that all vehicles be upgraded to protocol versions consistent with the platform. The method has the advantages that the TSP platform is complex in logic, redundant in data and difficult to maintain, different protocol requirements of different vehicle types or different OTA stages of the same vehicle type cannot be adapted efficiently, the method is difficult to implement because the vehicle upgrading rhythm is uncontrollable, and part of vehicles cannot interact with the cloud normally because of mismatching of protocol versions easily.
