Test method of unmanned vehicle

Abstract

The invention discloses the test method of an unmanned vehicle. The method comprises the following steps that a centralized control server carries out test scene initialization according to a preset test case; after the test initialization is completed, the centralized control server operates the test case, simultaneously triggers the unmanned vehicle in a test scene to carry out path planning according to a preset starting point and a preset end point, and travels according to a planned route and reports the real-time state of the vehicle; and during the operation process of the test case, for each test condition in the test case, the centralized control server carries out corresponding scheduling and control on a simulation device based on real-time state information of the current unmanned vehicle and the real-time state information of the simulation device in the test scene so as to complete the construction of a test condition. In the invention, the automatic test demand of a complex scene can be satisfied and the realization cost of the simulation device is low.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a test method for unmanned vehicles. Background technique [0002] With the accelerated popularization of 5G technology, the rapid promotion of Internet giants, and the maturity of automotive intelligent technology, the pace of the autonomous vehicle industry will continue to accelerate, and it is expected to achieve commercialization in 2020. [0003] Unmanned vehicles must pass closed field test verification, and only after comprehensive, systematic and objective testing and evaluation of vehicle functions and performance can they drive autonomously on open roads. [0004] In the existing unmanned vehicle field test technology, the simulation equipment mainly simulates people, bicycles, cars and other interference objects, and simulates sudden jumping, overtaking, slowing down, sudden braking, merging, turning and other operations to test unmanned vehicles. Whether the drivin...

AI Technical Summary

Problems solved by technology

In this method, the intelligent simulation device needs to realize some functions of the unmanned vehicle, for example, it can sense the external environment and obtain some operating conditions of the external equipment (including unmanned vehicles and other simulation equipment) (such as the speed of both, relative distance, etc.), and adjust its own behavior accordingly, the function is very powerful, but the design is too complicated, which leads to the abnormally high cost of intelligent simulation equipment

In addition, during the testing process of this method, the intelligent simulation device needs to decide its own behavior according to the real-time interaction with the external environment, while the intelligent simulation device cannot accurately collect some information related to the unmanned vehicle in real time during the test process. data for the intelligent simulation device to control its own behavior based on these data, so that the various simulation behaviors of the intelligent simulation device during the test cannot be pre-set

Furthermore, for the test case in the same field, the behavior of the intelligent simulation device cannot be kept consistent in different test processes, which will lead to deviation or failure of the test results, and the test success rate is very low, which cannot meet the requirements of the unmanned vehicle field test. automation needs

[0007] It can be seen that the existing test solutions for unmanned vehicles have problems such as only simple scene tests, high implementation costs, low test success rates, and inability to meet the automation requirements of unmanned vehicle field tests.
