Embodiment 1

[0047] Such as figure 1 As shown, an unmanned vehicle cooperative driving ability test method is used to test the unmanned vehicle's cooperative following driving ability on a long straight road. The test road is a long straight road B1 and B2 containing at least two lanes, and the middle lane line It is the white dotted line, the unmanned vehicle to be tested V1, the target vehicle V2, the control center Z1, the test start point L1, and the test end point L2; including the following steps:

[0048] Step 1. The safety officer drives the unmanned vehicle V1 to be tested to the test starting point L1 of the test lane B1 in the manual driving mode, and stops the unmanned vehicle V1 to be tested. The control center Z1 presets the following distance to be 10 meters.

[0049] Step 2: The control center Z1 controls the target vehicle V2 to drive to a safe distance of 50 meters in front of the same lane of the unmanned vehicle V1 under test.

[0050] Step 3. The safety officer sends a test r...

Embodiment 2

[0063] Such as figure 2 As shown, an unmanned vehicle cooperative driving ability test method is used to test the ability of the vehicle to cut in the adjacent lane on a long straight road, and the ability of the unmanned vehicle to slow down and avoid collisions. The test road is a long straight road containing at least two lanes B1 and B2, the middle lane line is the white dotted line, the unmanned vehicle to be tested V1, the target vehicle V2, the control center Z1, the test starting point L1, and the test end point L2; including the following steps:

[0064] Step 1. The safety officer drives the unmanned vehicle V1 to be tested to the test starting point L1 of lane B1 in the manual driving mode, and stops the unmanned vehicle V1 to be tested. The control center Z1 presets the following distance to be 10 meters.

[0065] Step 2: The control center Z1 controls the target vehicle V2 to drive to a safe distance of 50 meters in front of the adjacent lane of the unmanned vehicle V1 ...

Embodiment 3

[0075] Such as image 3 As shown, an unmanned vehicle cooperative driving capability test method is used to test the ability of the unmanned vehicle to recognize and drive stably when the vehicle in front of the same lane is cut out on a long straight road. The test road is a long straight road containing at least two lanes. B1 and B2, the middle lane line is a white dashed line, the unmanned vehicle to be tested V1, the target vehicle V2, the control center Z1, the test starting point L1, the test end point L2; including the following steps:

[0076] Step 1. The safety officer drives the unmanned vehicle V1 to be tested to the test starting point L1 of lane B1 in the manual driving mode, and stops the unmanned vehicle V1 to be tested. The control center Z1 presets the following distance to be 10 meters.

[0077] Step 2: The control center Z1 controls the target vehicle V2 to drive to a safe distance of 50 meters in front of the same lane of the unmanned vehicle V1 under test.

Abstract

The invention belongs to the field of unmanned vehicle performance testing. The invention discloses an unmanned vehicle cooperative driving capability test system and test method. The test system is simple in structure, the problem of high risk of an unmanned vehicle cooperative driving scene is solved; according to the method, the response capability of the to-be-tested unmanned vehicle is judgedby utilizing the speed relationship between the to-be-tested unmanned vehicle and a target vehicle and distance information between the to-be-tested unmanned vehicle and the target vehicle, so that the test of the cooperative driving capability of the unmanned vehicle is completed, the test efficiency is high, and the cost is low.

Description

Technical field [0001] The invention relates to the field of unmanned vehicle performance testing, in particular to an unmanned vehicle cooperative driving capability testing system and a testing method. Background technique [0002] With the development of society and economy and the continuous growth of human demand for a better life, driverless cars are gradually entering society and life, and are affecting the global economy and changing people’s lives at a rapid pace. the way. A scientific and complete test and evaluation system is essential to improve the efficiency of driverless car research and development, improve technical standards and laws and regulations, and promote the innovation and development of related industries. Before the public road test of unmanned vehicles, a large number of repeatable and different levels of test tests need to be carried out in a controllable real environment to ensure the safety of the autonomous vehicle's own functions and the reliabi...
