AI Technical Summary

Problems solved by technology

[0004] Although the information interaction between the real world and the simulation scene is realized in the above-mentioned simulation method, because the external information needs to be transmitted to the road traffic simulator through network simulation software, the efficiency of information transmission is not high, and the real-time performance is poor. At present, the research cost of communication middleware technology used in this method is high, the technology is not yet mature, there are many types of network emulators and frequent updates, the workload of organic combination of different platforms is huge, and the operability is not strong

In addition, this method mainly relies on simulation software to test related technologies of the Internet of Vehicles, and does not establish a mutual mapping model between the real scene and the simulation scene, and does not simulate real vehicles and traffic objects in the real scene into the simulation scene

All in all, this method is not flexible for the testing of Internet of Vehicles applications, and the practicability of the test information and the accuracy of the model cannot be guaranteed
