Example Embodiment

[0045] Example

[0046] In this embodiment, the test scenario used is constructed by simulation software, and the scenario elements in the test scenario come from a test scenario library stored in an Excel file.

[0047] like figure 1 As shown, it is a schematic diagram of the test scene selected by the virtual test system and test method for traffic coordination of autonomous vehicles based on the Turing idea in this embodiment according to the present invention. The test scene of this embodiment is a two-lane straight road. In the scene, there are respectively the vehicle A under test, the vehicle B controlled by the tester through the driving simulator, the vehicle C driving straight at a constant speed at a specific speed, and the vehicle controlled by the traffic flow simulation software. Background vehicles D and E behave randomly but do not interfere with the driving of vehicles A, B, and C. In the test scene of this embodiment, the lighting conditions are good and th...

Abstract

The invention relates to an autopilot vehicle transportation coordination virtual testing system and testing method. A system hardware-in-the-loop simulation testing method is planned, a correspondinginteractive testing scenario is arranged in a virtual simulation platform according to test requirements, one or more autopilot vehicle intelligent controllers are to-be-tested subjects, and occupants of a virtual to-be-tested vehicle and other virtual transportation participants are introduced through methods, such as a driving simulator and a VR device, to simulate the multi-vehicle interactionscene under complex traffic stream. Trajectories of all virtual transportation participants, including that of the virtual to-be-tested vehicle, subjective judgments of the controllers of the virtualto-be-tested vehicle occupants and other virtual transportation participants, and various physiological indicators related to interaction comfort are collected, multi-scenario autopilot vehicle transportation coordination tests at different penetration rates are undergone to verify whether the autopilot vehicle is capable of interacting well with other transportation participants during driving or not.

Description

technical field [0001] The invention relates to the technical field of automatic driving vehicle testing, in particular to a virtual testing system and method for traffic coordination of automatic driving vehicles. Background technique [0002] With the continuous upgrading and popularization of technology and products, in the foreseeable future, there will be situations where self-driving cars and vehicles driven by human drivers are driving on the road at the same time, which will have an impact on the existing traffic conditions. [0003] Since the planning methods of self-driving cars are bound to be different from those of human drivers, this will make self-driving cars and human-driven vehicles not adapt to each other's behavior, which will cause traffic coordination problems. Therefore, it is necessary to combine the characteristics of rich scene types and high test iteration efficiency of virtual test to carry out tests for the traffic coordination problem of autonom...
