Embodiment 1

[0053] This embodiment provides a method for testing the avoidance ability of an emergency vehicle of an unmanned vehicle, including: performing scene layout on the test field and responding to the vehicle to be tested;

[0054] The scene layout is:

[0055] The test field includes a road, the vehicle to be tested 2 is placed on the road a, the reference vehicle 3 is controlled to drive in front or behind the same lane as the vehicle to be tested 2 or an adjacent lane, and the reference vehicle 3 and the vehicle to be tested 2. Keep the avoidable distance, and control the emergency vehicle 1 to approach the vehicle 2 under test from the rear of the same lane or the adjacent lane with the vehicle 2 under test;

[0056] The emergency vehicle in this embodiment is an ordinary vehicle controlled manually.

[0057] The response of the vehicle to be tested is:

[0058] When the emergency vehicle approaches the vehicle to be tested from the rear of the same lane or adjacent lanes of ...

Embodiment 2

[0096] On the basis of Embodiment 1, this embodiment provides a specific implementation of a method for testing the avoidance ability of an unmanned emergency vehicle.

[0097] Such as figure 1 , the road a is one-way with two lanes, the emergency vehicle 1 is a human-driven vehicle, the test vehicle 2 and the reference vehicle 3 are unmanned vehicles. Place the emergency vehicle 1 and the reference vehicle 3 in the right lane, and the reference vehicle 3 is located 30m in front of the emergency vehicle 1; place the test vehicle 2 in the left lane, and the initial position is aligned with the emergency vehicle 1.

[0098] Simultaneously start the emergency vehicle 1, the vehicle to be tested 2 and the reference vehicle 3, and accelerate uniformly to 30km / h, 40km / h and 30km / h respectively. The emergency vehicle 1 is controlled to accelerate uniformly to 45km / h, and when approaching the vehicle under test 2 from the right rear, an early warning message is sent to the vehicle un...

Embodiment 3

[0100] On the basis of Embodiment 1, this embodiment provides a specific implementation of a method for testing the avoidance ability of an unmanned emergency vehicle.

[0101] Such as figure 2 , the test field includes straight road a, emergency vehicle 1, vehicle to be tested 2 and reference vehicle 3. The straight road a is a one-way two-lane road, the emergency vehicle 1 is a human-driven vehicle, and the test vehicle 2 and the reference vehicle 3 are unmanned vehicles. Place the emergency vehicle 1 and the vehicle under test 2 on the left lane, and the vehicle under test 2 is located 30m in front of the emergency vehicle 1; place the reference vehicle 3 on the right lane, and the initial position is aligned with the emergency vehicle 1.

[0102] Simultaneously start the emergency vehicle 1, the vehicle to be tested 2 and the reference vehicle 3, and accelerate uniformly to 35km / h, 35km / h and 30km / h respectively. The emergency vehicle 1 is controlled to accelerate unifo...

Abstract

The invention provides an unmanned vehicle emergency vehicle avoidance capacity test method and a test field. The test method comprises the steps that scene arrangement for the test field and responding to a to-be-tested vehicle are performed, wherein scene arrangement is performed as follows: the test field comprises a road, and the to-be-tested vehicle is arranged on the road; a reference vehicle is controlled to run in front or back of the same lane or the adjacent lane of the to-be-tested vehicle, and the reference vehicle keeps an avoiding distance with the to-be-tested vehicle; an emergency vehicle is controlled to be close to the to-be-tested vehicle from the rear part of the same lane or the adjacent lane of the to-be-tested vehicle; the step of responding to the to-be-tested vehicle is carried out as follows: when the emergency vehicle is close to the to-be-detected vehicle from the rear part of the same lane or the adjacent lane of the to-be-tested vehicle, the to-be-tested vehicle makes an action of avoiding the emergency vehicle, and the emergency vehicle runs preferentially.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle performance testing, in particular to a test method and a test site for an emergency vehicle avoidance ability of an unmanned vehicle. Background technique [0002] As the future research direction of automobiles, unmanned driving has a profound impact on the automobile industry and even the transportation industry. The advent of driverless cars will liberate human hands, reduce the frequency of traffic accidents, and ensure people's safety. At the same time, with the breakthrough and continuous advancement of core technologies such as artificial intelligence and sensor detection, unmanned driving will become more intelligent, and at the same time, it will be able to realize the industrialization of unmanned vehicles. [0003] But the emergence of any technology is a process of gradual and continuous innovation. The recent frequent accidents of self-driving vehicles such as Uber and Tesl...
