Abstract

The invention relates to a vehicle-road cooperative application scale evaluation system and method. The system comprises a scene simulation subsystem, a test bed subsystem, a data acquisition subsystem and a test evaluation subsystem; the scene simulation subsystem is used for configuring test scene information and dynamically adjusting the test scene information according to the motion state dataof the tested vehicle; the test bed subsystem comprises a node controller and a background V2X node, and the node controller is used for controlling the working mode of the background V2X node; the data acquisition subsystem is used for acquiring motion state data of a tested vehicle carrying a tested V2X node and feeding back the motion state data to the scene simulation subsystem; and the testevaluation subsystem is used for analyzing and evaluating the test data according to a preset test standard and generating a test result and a report. By simulating one or more background V2X nodes, the communication background environment matched with the actual situation of the road is formed, and then large-scale and intelligent evaluation of the tested V2X nodes and services can be achieved.

Description

technical field [0001] This application relates to the technical field of intelligent networked vehicles, in particular to a scale evaluation system and method for vehicle-road collaborative applications. Background technique [0002] Vehicle-road coordination technology refers to the technology that uses vehicle-mounted and roadside nodes to form a proprietary network to collect and transmit relevant information such as vehicle attitude and road conditions to enhance the perception of the automatic driving system. It is a key technology for realizing fully automatic driving. one. [0003] Vehicle-road coordination technology should emphasize the synergy between the vehicle and the outside world. How to test the performance of nodes in a complex environment and make the test results closer to the performance in the real environment has gradually become the focus of the industry. However, at present, the test equipment and test methods of vehicle-road coordination technolog...
