Problems solved by technology

However, the above-mentioned communication test method forms an interference environment through signal interference facilities, which is still different from the real environment where signal interference exists. There is interference, the above communication test method cannot accurately reproduce the interference environment, resulting in differences in the communication test of V2X technology

Embodiment 1

[0025] V2X test method in complex communication environment, as attached figure 1 shown, including the following steps:

[0026] Test preparation steps: select the test site and the test vehicle. The test site has at least two lanes, and roadside equipment (RSU) is installed at both ends of the test site. The number of roadside equipment is two, and the interval is 300 meters. The test vehicle includes a test vehicle and at least three background vehicles. In this embodiment, the test site has three lanes, and the number of background vehicles is four. The test vehicles are equipped with a V2X communication module and a communication test module. The V2X communication module is a wireless communication system with a V2X communication protocol. In this embodiment, the V2X communication modules on different test vehicles are different V2X communication products. The V2X communication modules on different test vehicles can exchange information, and the communication test module ...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 lies in that in this embodiment, the number of lanes of the test field and the number of background cars are different.

[0035] In the test preparation step of the V2X test method in a complex communication environment, the test site is two lanes, and the number of background cars is three; In the test step, place the test vehicle in another lane of the test site.

Embodiment 3

[0037] The difference between this embodiment and Embodiment 1 is that, in addition to conventional emergencies, there will be other situations caused by changes in the external environment and human factors during the driving process of a V2X-based vehicle, for example, there are people in the vehicle. Using WIFI, the change and flickering of the lights of the front car on the road, the exhaust emission of large trucks, etc., the use of WIFI will occupy the frequency band used by V2X, causing communication problems, and the change and flicker of lights and the emission of exhaust gas will cause changes in light and shade , For vehicles using VX technology, the light and shade changes will cause errors in the vehicle's recognition of the external environment.

[0038] The V2X testing method in a complex communication environment further includes an environment changing step and a test monitoring step.

Abstract

The invention relates to the technical field of vehicle performance testing, in particular to a V2X test system and method in a complex communication environment, and the method comprises the following steps: a test preparation step: enabling a test vehicle to be provided with a V2X communication module and a communication test module, wherein the V2X communication module can perform information interaction, and the communication test module performs communication monitoring on the V2X communication module; a test step: placing the test vehicle on any lane in the test field, and placing the background vehicles around the test vehicle respectively; enabling the test vehicles to run at a set speed; recording the communication monitoring result of the communication test module and the drivingresult of the test vehicle; and a test analysis step of judging whether the communication between the test vehicles is normal or not according to the communication monitoring result, the driving result including successful driving and failed driving, and when the communication is normal and the driving result is successful driving, the test succeeds. By the adoption of the scheme, communication testing can be conducted on the V2X technology in the signal interference environment among various vehicles, and the accuracy of the testing result is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle performance testing, in particular to a V2X testing system and method in a complex communication environment. Background technique [0002] With the development of automobile technology, people's functional requirements for automobiles are no longer limited to the ability to drive, but they hope to obtain more functions to ensure the safety of drivers or vehicles. It is in this environment that V2X technology emerged. V2X technology is a special embodiment of the Internet of Things, that is, the information interaction between the vehicle and the outside world, and the information of the outside world can be obtained through information interaction. In the event of an emergency, the vehicle can be controlled. Quickly make adjustments to avoid traffic accidents and ensure the safety of drivers and vehicles. At present, V2X technology is a hotspot of intelligent vehicle networking. When people have...
