Embodiment 1

[0035] refer to figure 1 , in this embodiment, firstly, a static obstacle response performance test field of an autonomous vehicle is provided. The test field consists of a road with two lanes and static obstacles (see figure 1in the warning bucket 1). Among them, the two lanes include the starting lane 3 of the vehicle to be tested and the detour lane 4 of the vehicle to be tested, the static obstacle is placed on the starting lane 3 of the vehicle to be tested, and the starting point of the static obstacle and the starting lane 3 of the vehicle to be tested There is an operable distance for vehicle lane change, that is, when the vehicle under test 2 is at the starting point of the vehicle under test lane 3, the static obstacle is located in front of the vehicle under test 2, and the distance between the static obstacle and the vehicle under test 2 The distance is at least enough for the vehicle under test 2 to find static obstacles and be able to change lanes to avoid stat...

Embodiment 2

[0058] refer to figure 2 , in this embodiment, the test field is based on the first embodiment:

[0059] The test field also includes an operation test management center 5 capable of sending and receiving information. In this embodiment, the operation test management center 5 can receive the warning information sent by the vehicle 2 to be tested, and send the road condition information to the vehicle 2 to be tested. Specifically, the operation test management center 5 includes a wireless communication device with a V2N (vehicle and cloud) communication protocol to realize a communication connection with the vehicle 2 to be tested, and then receive early warning information sent by the vehicle 2 to be tested and send a message to the vehicle 2 to be tested. traffic information. In this embodiment, the road condition information can be pre-programmed and stored in the operation test management center 5; or, the operation test management center 5 includes an analysis module fo...

Embodiment 3

[0070] refer to image 3 , in this embodiment, the test field is based on the first embodiment:

[0071] The test field also includes roadside equipment 6, which is arranged on the side of the road, facing or adjacent to static obstacles. An early warning message is sent to the vehicle 2 to be tested when a road condition with a static obstacle is received or a road condition with a static obstacle is received manually.

[0072] Specifically, the roadside equipment 6 includes a detector capable of automatically detecting road conditions and / or an input terminal for manually inputting road conditions. Communication equipment, the detector detects road conditions through monitoring means such as roadside camera, millimeter wave radar, infrared, etc., and the processing module analyzes and processes the road condition related information received from the detector and / or input terminal to form early warning information, through the V2I communication protocol The wireless commun...

Abstract

The invention relates to the automatic driving vehicle performance test technology field and especially relates to a static obstacle response performance test method of an automatic driving vehicle and a test field. In the test method, the test field comprises a road having at least two lanes and a static obstacle. A vehicle to be detected and the static obstacle are arranged in a same lane. A vehicle lane changing operability distance is arranged between the static obstacle and the vehicle to be detected. The test field is similar to an actual driving environment so that a test result can accurately reflect response performance of the vehicle to be detected to the static obstacle. A response of the vehicle to be detected is limited to be a condition that the vehicle runs towards the static obstacle and changes the lane so as to avoid the static obstacle. Evaluation of static obstacle response performance of the vehicle is standardized and the test result is authoritative and reliable. The test field provided in the invention can make the test result accurately reflect the response performance of the vehicle to be detected to the static obstacle and can be served as a standard scene.

Description

technical field [0001] The present invention relates to the technical field of performance testing of self-driving vehicles, in particular to a static obstacle response performance testing method and test field of self-driving vehicles. 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 assiste...
