Simulation test method of vehicle-mounted short-distance communication network based on real-time traffic road condition

Abstract

The invention provides a simulation test method of a vehicle-mounted short-distance communication network based on a real-time traffic road condition. After a road is restored according to road static information and latitude and longitude information, road condition mapping is constructed based on road dynamic information and road restoration information to obtain a real-time traffic restoration scene. A plurality of dynamic test areas are set, and each dynamic test area synchronously / asynchronously performs radio wave transmission performance test, data packet collision performance test and application scene test. The method has the advantages that real-time traffic information and road information are converted into vehicle information of an actual road, and simulation of a real-time actual road scene corresponding to V2X is achieved. According to the method, various V2X algorithms are tested in a real-time and actual road scene, simulation and performance testing of actual scenes of actual roads in different time periods and different areas are achieved, the performance of various algorithms in the actual roads is obtained, and therefore an approximately real testing environment is provided for various V2X algorithms.

Description

technical field [0001] The invention relates to the technical field of vehicle communication networks, in particular to a simulation test method for a vehicle short-distance communication network based on real-time traffic conditions. Background technique [0002] Vehicle to X (Vehicle to X: V2X) network is the communication between inside the vehicle, on the road, in the workshop, outside the vehicle, and between people and vehicles through short-range communication technologies such as wireless communication, GPS / GIS, and sensors. V2V can Greatly improving road safety, C-V2X (cellular V2X) has become an important part of the 5G standard. However, many new algorithms and technical solutions need to go through a large number of tests on actual roads to verify their feasibility and find problems for improvement. This requires a large number of vehicles with V2X vehicle nodes installed on various actual roads with roadside nodes and test in traffic conditions. Since all vehi...
