V2X Internet of Vehicles on-loop simulation system

Abstract

The invention discloses a V2X Internet of Vehicles (IoV) on-loop simulation system, and belongs to the field of IoV. The system is mainly composed of an IPG carmaker IoV simulation platform (01), a Simulink environment module (02), a channel simulator (03), a V2X communication terminal (04) and a V2X road side device (05), wherein the IPG carmaker simulation tool is responsible for building a simulation scene and configuring simulating parameters, the Simulink environment module is responsible for building a channel model, a simulation scene and real scene mapping model, a control model and acommunication model, the channel simulator is used for conducting performance test on LTE-V, 802. 11p communication protocol, the V2X communication terminal is connected with the Simulink communication model to obtain the scene information and realize on-loop simulation, and the V2X road side device imports the obtained information of the real scene into a simulation scene to achieve an outdoor test function. All the modules supplement each other to form a perfect on-loop simulation system and provide a good testing and verifying platform for the IoV application.

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 org...
