Embodiment 1

[0036] refer to figure 1 , in this embodiment, firstly, a test field for the ability of the autonomous vehicle to pass through the visual interference zone is provided. The test field includes a road 1, and the road 1 includes a visually disturbing section 12 and a non-visually disturbing section 11. The visually disturbing section 12 is correspondingly provided with visually disturbing facilities 2, or the visually disturbing section 12 includes continuously arranged road surfaces of different materials. It can be understood that the formation of the visually disturbing road section 12 (ie, the visually disturbing area) is due to the setting of the visually disturbing facilities 2 or the setting of road surfaces of different materials. In this embodiment, the visually disturbing section 12 is formed by setting visually disturbing facilities 2 .

[0037] The process of applying this test field for testing is:

[0038] The vehicle 3 to be tested is placed on the road section ...

Embodiment 2

[0061] refer to figure 2 , in this embodiment, the test field is improved based on Embodiment 1, as follows:

[0062] The test field also includes an operation test management center 4 capable of sending and receiving information. The operation test management center 4 can send the first road information to the vehicle under test 3 before the vehicle under test 3 enters the visually disturbing road section 12 . Of course, the operation test management center 4 can also send the first road information to other vehicles on the passing road 1 .

[0063] Specifically, the operation test management center 4 includes a wireless communication device with a V2N (Vehicle to Cloud) communication protocol to realize a communication connection with the vehicle 3 to be tested. The test vehicle 3 sends the first road information. Wherein, the first road information can be pre-programmed and stored in the operation test management center 4; perhaps, the operation test management center 4 ...

Embodiment 3

[0076] In this example, you can continue to refer to figure 2 , the test field is improved on the basis of Example 2:

[0077] The operation test management center 4 can also send the second road information to the vehicle under test 3 through the wireless communication device with the V2N communication protocol when the vehicle under test 3 is driving on the visual interference road section 12 . Specifically, the control module of the operation test management center 4 controls the wireless communication device with the V2N communication protocol to send the second road information to the vehicle under test 3 when the vehicle under test 3 is driving in the visual interference road section 12 . Of course, the operation test management center 4 can also send the second road information to other vehicles passing the road.

[0078] Wherein, the second road information can be pre-programmed and stored in the operation test management center 4; perhaps, the operation test managem...

Abstract

The invention relates to the technical field of automatic driving vehicle performance testing, especially to a testing method and testing field for testing the capability of passing by a visual interference region by an automatic driving vehicle. The testing field employed by the testing method consists of a road including a visual interference section and a non-visual-interference section; and visual interference equipment is arranged at the visual interference section correspondingly or the visual interference section includes pavements that are made of different materials and are arranged continuously. Compared with a simulated environment only with the reduced illumination intensity in a laboratory and theoretical data of computer-simulation traffic operation software, the testing field is close to a practical driving environment, so that the testing result can represent the capability of passing by a visual interference region by a to-be-tested vehicle accurately. Moreover, compared with a method with actual road testing, the provided testing method is secure. The testing field and the testing method are suitable for different automatic driving vehicles; evaluation on the capability of passing by a visual interference region by a vehicle is standardized; and the testing result is authoritative and reliable.

Description

technical field [0001] The invention relates to the technical field of self-driving vehicle performance testing, in particular to a test method and a test field for the ability of an automatic driving vehicle to pass through a visual interference zone. Background technique [0002] There are mainly five levels of automatic driving, level 0 is no automatic driving, level 1 is assisted driving such as infotainment and navigation, level 2 is assisted driving such as traffic safety and traffic efficiency (mainly manual), and level 3 is specific conditions / roads Level 4 is all-weather, all-road autonomous driving. Level 1 to level 3 can be called assisted driving, and level 4 is unmanned driving. Therefore, autonomous vehicles include assisted driving vehicles, which assist the driver in driving, and unmanned vehicles, which drive fully autonomously. [0003] At this stage, the research on autonomous driving at home and abroad is gradually deepening, and it is constantly advanc...
