Embodiment 1

[0052] see figure 1 , which is a structural diagram of a test system provided by the embodiment of the present application, which is applied to test the electromagnetic compatibility performance of vehicles and / or the performance of vehicle antennas. The system may include: a first dark room 10 and a second dark room 20 .

[0053] The first dark room 10 is used for testing the electromagnetic compatibility performance of the whole vehicle.

[0054] The second dark room 20 is used for testing the performance of the whole vehicle antenna.

[0055] Wherein, the first dark room and the second dark room are connected by a movable wall, and when the electromagnetic compatibility performance and / or the vehicle antenna performance of the vehicle in the V2X communication state are detected, the movable wall is moved so that the first The darkroom communicates with the second darkroom. In practical applications, the testing system may further include a movable wall preparation area, a...

Abstract

The embodiment of the invention provides a test system and a vehicle test method. The test system is applied to test the electromagnetic compatibility performance and / or the whole vehicle antenna performance of a vehicle, and the system comprises a first darkroom used for detecting the whole vehicle electromagnetic compatibility performance of the vehicle, the first darkroom being a semi-anechoicchamber; a second darkroom, used for detecting the whole vehicle antenna performance of the vehicle, the second darkroom being a full anechoic chamber. The first darkroom and the second darkroom are connected through a movable wall body, and when the electromagnetic compatibility and / or the whole vehicle antenna performance of the vehicle in the V2X communication state are / is detected, the movablewall body is moved, so that the first darkroom and the second darkroom are communicated. Visibly, through the test system provided by the embodiment of the invention, when the vehicle is in the V2X communication state, the EMC performance and / or the whole vehicle antenna performance of the vehicle can be tested by utilizing the test system.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a test system and a vehicle test method. Background technique [0002] With the continuous development of the automobile industry, people's demand for automobiles is increasing. With the continuous increase in the number of automobiles, traffic safety issues have become a worldwide problem, and traffic accidents cause hundreds of thousands of casualties every year. [0003] Among them, the most important reason for traffic accidents is that there is no timely communication between the colliding vehicles to grasp the current traffic conditions. In order to solve this problem, V2X (Vehicle to X) technology is proposed, where X can be infrastructure (Infrastructure), vehicles (Vehicle), people (Pedestrian) and so on. V2X technology is mainly used to realize communication between vehicles, vehicles and roadside facilities, and vehicles and the Internet, so that a serie...
