Embodiment 1

[0075] refer to figure 2 , showing a basic flow chart of an unmanned vehicle response agility evaluation method of the present invention, as figure 2 As shown, the method specifically includes the following steps:

[0076] Step 201. Evaluate the complexity of the traffic environment in which the unmanned vehicle is located, and obtain the environment complexity index M1;

[0077] Specifically, the test environment for the agility of unmanned vehicles can be set through a virtual scene simulation system, which mainly provides virtual traffic scenes for unmanned vehicles and provides conditions for testing and evaluating the agility of unmanned vehicles to emergencies . A main vehicle is set in the virtual traffic scene. The main vehicle is the mapping of the tested unmanned vehicle in the virtual traffic scene. The main vehicle obtains the speed, acceleration, steering wheel angle and other parameters of the tested unmanned vehicle in real time to realize autonomous driving...

Embodiment 2

Abstract

The embodiment of the invention provides an unmanned vehicle reaction agility evaluation method, which comprises the following steps: evaluating the traffic environment complexity of the unmanned vehicle, obtaining an environment complexity index M1; Evaluating driving behavior of unmanned vehicles and obtaining driving behavior index Bk; obtaining a real-time performance index M2; a weighted sumof M1, Bk and M2 is obtained to obtain an unmanned vehicle agility score M, and a reaction agility level grade of the unmanned vehicle is determined according to the unmanned vehicle agility score M.In accordance with that above manner, the method to evaluate the response agility of unmanned vehicle can be provided. The method analyzes the response agility of unmanned vehicle from three dimensions: environmental complexity, driving behavior and real-time operation, and can obtain scientific and effective evaluation results, so as to ensure the stable, safe and reliable driving of unmanned vehicle in the real environment. The embodiment of the invention also provides an unmanned vehicle reaction agility evaluation device.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a method and device for evaluating the response agility of an unmanned vehicle. Background technique [0002] With the support of the national strategy and the introduction of the concept of intelligent networked vehicles, research on unmanned vehicles has attracted great attention. Unmanned vehicles are equipped with on-board sensors, controllers and other devices, with functions such as positioning and navigation, environmental perception, decision-making control, path task planning and execution. At present, mainstream car companies and Internet companies at home and abroad are actively researching unmanned driving related technologies and developing unique unmanned vehicles, such as Tesla, Google unmanned vehicles, Baidu unmanned vehicles, etc. . [0003] However, at this stage, unmanned driving technology is still a certain distance from the realization of driving ...
