V2X vehicle-mounted terminal vehicle-vehicle early warning function simulation test method

Abstract

The invention belongs to the technical field of intelligent networked vehicles, and particularly relates to a V2X vehicle-mounted terminal vehicle-vehicle early warning function simulation test method, which comprises the following steps: 1, simulation software runs on a PC, and a V2X vehicle-vehicle early warning function test scene is established in the simulation software; 2, information of the vehicle is sent to a vehicle-mounted terminal OBU of the vehicle in simulation software; the information of the remote vehicle is sent to a remote vehicle-mounted terminal OBU in the simulation software; 3, the remote vehicle-mounted terminal OBU sends the remote vehicle information to the vehicle-mounted terminal OBU of the vehicle; the vehicle-mounted terminal OBU of the vehicle outputs a corresponding actual early warning signal; and 4, the actual early warning signal is output to the simulation software of the PC, the actual early warning signal and the expected early warning signal are displayed in the same interface of the simulation software, and compared and observed in real time. According to the method, the test result can be visually observed in real time.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked vehicles, and in particular relates to a V2X vehicle terminal vehicle early warning function simulation test method. Background technique [0002] At present, some related schemes of V2X vehicle terminal vehicle early warning function simulation test methods are mainly based on PreScan, SUMO and other simulation software, Ubuntu system desktop computer, vehicle terminal OBU of the vehicle, and vehicle terminal OBU of the remote vehicle. Establish a test scene in the simulation software. The simulation software runs on the desktop computer of the Ubuntu system. The simulation software sends the motion status information and GPS information of the vehicle and the remote vehicle to the vehicle-mounted terminal OBU of the vehicle and the vehicle-mounted terminal OBU of the remote vehicle, and the vehicle-mounted terminal OBU Through the standard air interface communication, the vehicle-m...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing system is developed and integrated based on PreScan, SUMO and other simulation software. These simulation software cannot effectively import and modify external OpenDrive and OpenScenario standard format scene libraries; at the same time, they cannot effectively export OpenDrive and OpenScenario standard format scene libraries, so they cannot Make full use of the established standard scene library and cannot export the scene established in the simulation software as a standard scene library, resulting in low versatility and utilization of the scene library, and a lot of repetition and low efficiency in the application of the scene library work;

[0004] 2. The information sent by the existing system simulation software to the vehicle-mounted terminal OBU of the local vehicle and the vehicle-mounted terminal OBU of the remote vehicle is generally transparently transmitted, which is not a standard BSM message layer message, which is not conducive to the standardization and versatility of the test system interface;

[0005] 3. There is no expected early warning signal in the existing system, and there is no comparison display interface between the actual early warning signal and the expected early warning signal of the vehicle-mounted terminal OBU, and the test results cannot be observed intuitively in real time
