A method for implementing vehicle-road co-simulation test

Abstract

The invention relates to the technical field of test simulation, and discloses a vehicle-road collaborative simulation test implementation method, including a "pull-distance" V2X end-to-end delay and packet loss rate test implementation method, and realizes the scene based on injected recording data The test implementation method of the playback function, the implementation method of the mobile APP accessing the OBU to realize the visual V2X scene test, and the front-end can edit the JSON file of the V2X message in real time and send it to the OBU to simulate and trigger different V2I scenarios. Four modules; one of them The "distance-type" V2X end-to-end delay and packet loss rate test implementation method includes the following steps: S1. The sending end will set the transmission parameters. The present invention uses a "distance-type" V2X end-to-end The implementation method of delay and packet loss rate test is conducive to the configuration of the transmission data length and transmission frequency when testing V2X performance indicators, and can observe the packet reception rate, delay, and test distance in real time without additional distance measurement work.

Description

technical field [0001] The invention relates to the technical field of test simulation, and more particularly to a vehicle-road collaborative simulation test implementation method. Background technique [0002] Vehicle-road coordination is to use advanced wireless communication and new-generation Internet technologies to implement dynamic real-time information interaction between vehicles and vehicles, and to carry out vehicle active safety control and road coordination on the basis of full-time and space dynamic traffic information collection and fusion. management, fully realize the effective coordination of people, vehicles, and roads, ensure traffic safety, and improve traffic efficiency, thereby forming a safe, efficient and environmentally friendly road traffic system. A real vehicle test will be carried out, and a real vehicle test will be carried out after a lot of calculations are performed during the test. [0003] Under the existing technology: the test of the ve...

Problems solved by technology

[0003] Under the existing technology: the test of the vehicle-road coordination system adopts the real vehicle test, and the cost of the real vehicle test is high, and the number of final product tests in the real vehicle test will be reduced in consideration of the cost. , and the current vehicle-road collaborative test simulation scheme is basically blank for the realization of vehicle-road collaborative test verification, so a vehicle-road collaborative simulation test implementation method is needed
