Abstract

The invention discloses a V2X communication and application joint testing method and system. The method builds test systems corresponding to different test scenarios in different test sections of the test site. When the node is powered on, the server receives the online request of the node and compares it with the Bound test scenarios; select communication environment test scenarios and send environment configuration information to participating roadside nodes; determine the number and location of RVs in the application scenarios and generate corresponding BSM message flows; HVs start moving and execute message sending and receiving according to the application process , the server collects communication data information of roadside nodes, HV nodes and RV nodes, and conducts joint test analysis of communication and applications. The invention carries out two kinds of tests under the same platform, which is beneficial to improving the applicable surface of the platform and rapid diagnosis of safe application development. The present invention simply and flexibly controls the V2X application flow, accurately reproduces the application scene; uses roadside nodes to simulate actual vehicles to avoid possible safety problems such as collisions in the test.

Description

technical field [0001] The invention belongs to the technical field of field testing, and relates to a V2X communication and application joint testing method and system. Background technique [0002] In the process of market-oriented development, automakers are concerned about how to evaluate the overall performance of V2V (Vehicle-to-Vehicle) components. Many scholars use the simulation platform for research testing, but the simulation platform usually has the characteristics of idealization, ignoring many realistic factors, and the simulation process cannot be used to complete the vehicle function test. In order to overcome the limitations of research based on theoretical simulation, the test of vehicle-to-vehicle communication must restore the real scene. Most automakers believe that field testing is a feasible solution, and real vehicle testing in real scenarios can provide researchers with more realistic and reliable research data. In the past few years, researchers a...
