Embodiment 1

[0037] refer to figure 1 , in this embodiment, firstly, a test field for the ability of an automatic driving vehicle to avoid approaching vehicles is provided.

[0038] The test site includes a road 1 and a first reference vehicle 2. The first reference vehicle 2 can run with an avoidable distance in front of or behind the vehicle 3 to be tested, or run side by side with the vehicle 3 to be tested, or drive with the vehicle 3 to be tested. 3 driving opposite to the vehicle 3 to be tested on the adjacent lane, and then the vehicle speed and / or driving direction can be changed to approach the vehicle 3 to be tested.

[0039] In this embodiment, the road 1 is a one-way street, and the first reference vehicle 2 is driving in front of the vehicle under test 3, and keeps an avoidable distance with the vehicle under test 3, that is, the vehicle under test 3 and the first reference vehicle 2 are at the first Before a reference vehicle 2 changes its speed or direction of travel, the d...

Embodiment 2

[0067] refer to figure 2 , in this embodiment, the test field is improved on the basis of Embodiment 1, as follows:

[0068] In this embodiment, the first reference vehicle 2 runs behind the vehicle under test 3 , that is, the first reference vehicle 2 follows the vehicle under test 3 , and the first reference vehicle 2 and the vehicle under test 3 maintain an avoidable distance. Then, the first reference vehicle 2 increases the driving speed. At this time, the distance between the vehicle under test 3 and the first reference vehicle 2 is continuously decreasing. If the vehicle under test 3 does not make an action to avoid the first reference vehicle 2, then the vehicle under test 3 will collide with the first reference vehicle 2 . Wherein, the avoidance action made by the vehicle under test 3 may be an action that can avoid or slow down the collision with the first reference vehicle 2 , such as changing lanes.

[0069] Further, in this embodiment, when the first reference ...

Embodiment 3

[0077] refer to image 3 , in this embodiment, the test field is improved on the basis of Embodiment 1, as follows:

[0078] In this embodiment, the road 1 has at least two lanes, and the first reference vehicle 2 runs side by side with the vehicle under test 3 in the adjacent lane of the vehicle under test 3 . Then, the first reference vehicle 2 changes direction of travel, (for example with reference to image 3 The dotted arrow in , the first reference vehicle 2 is obliquely inserted in front of the vehicle under test 3 to enter the lane where the vehicle under test 3 is located), at this time the distance between the vehicle under test 3 and the first reference vehicle 2 is continuously decreasing, if the vehicle under test 3 If no action is taken to avoid the first reference vehicle 2 , then the vehicle under test 3 will collide with the first reference vehicle 2 . Wherein, the avoidance action made by the vehicle 3 to be tested may be an action that can avoid or slow d...

Abstract

The invention relates to the technical field of autonomous driving vehicle performance tests, in particular to a test method and a test field for capacity of an autonomous driving vehicle in avoiding an approaching vehicle. The test field and a test field in the test method each comprise a road and a first reference vehicle. The scenes are configured to control the first reference vehicle to drive in front of or behind a vehicle to be tested in a manner of keeping an avoidable distance with the vehicle to be tested, control the first reference vehicle and the vehicle to be tested to drive side by side, or control the first reference vehicle to drive in an opposite direction of the vehicle to be tested on a lane adjacent to that of the vehicle to be tested, and then control the first reference vehicle to change velocity and / or driving direction to approach the vehicle to be tested. Therefore, the scenes are closer to the real driving environment, so that test results can show the capacity of the vehicle to be tested in avoiding the approaching vehicle more precisely, and the test method is safer when compared with a method adopting a real road for testing; in addition, the scenes are arranged to cooperate with the response of the vehicle to be tested, the evaluation on the capacity of the vehicle in avoiding the approaching vehicle is standardized, and the test results are 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 site for the ability of an automatic driving vehicle to avoid approaching the vehicle. 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 advancing from as...
