V2X test method and system

Abstract

The invention provides a V2X test method and a system. The V2X test system comprises a simulation system, a vehicle dynamics model system and tested equipment. The method comprises the steps of building a virtual test scene by using a simulation system, wherein the virtual test scene comprises lanes, a main vehicle virtual simulation vehicle model corresponding to the tested equipment and an infrastructure equipment model; in the test stage, the simulation system outputs main vehicle information and peripheral equipment information to the tested equipment; the main vehicle information and theperipheral equipment information are used for the tested equipment to generate a control command; the simulation system receives a vehicle control command returned by the vehicle dynamic model system;the vehicle control command is obtained by converting the control command by the vehicle dynamic model system; and the simulation system dynamically displays the main vehicle virtual simulation vehicle model according to the vehicle control command. By using the technical scheme provided by the invention, the participation of a real vehicle is not needed, so that the test can be carried out without producing a sample vehicle, the vehicle model research and development period is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of simulation, in particular to a V2X testing method and system. Background technique [0002] In recent years, the development of intelligent transportation systems has been booming, and V2X (vehicle to everything) technology, as an important part of it, has attracted widespread attention from all walks of life. V2X refers to the information interaction between the vehicle and the outside world, where X can refer to infrastructure equipment, including but not limited to: onboard unit (Onboard Unit, OBU), roadside unit, signal light controller that can send phase signals and related prediction information, Base stations, mobile phone bracelets worn by pedestrians, etc. [0003] Therefore, V2X communication, including but not limited to communication between OBU (Vehicle To Vehicle, V2V), OBU and roadside unit communication (Vehicle To Infrastructure, V2I), OBU and pedestrian equipment communication (Vehicle to Pedest...

AI Technical Summary

Problems solved by technology

[0007] First of all, the use of real vehicles to test the V2X function is based on the production of real vehicles. For new models, this work requires the production of prototype vehicles before testing, prolonging the development cycle of the entire model and increasing costs.

[0008] Secondly, the road environment will affect the verification effect. In the actual vehicle test, in order to fully test the V2X function, a more complex road environment and vehicle environment are required, including a number of V2X basic working conditions involving pedestrians and roadside units. The environment has high requirements, and it is difficult for the test scenarios to meet all the test requirements. For example, some scenarios involve the participation of pedestrians, and some scenarios require the main vehicle to be closer to the distant vehicle. These have safety problems in real tests and require more Measures to ensure safety
