Problems solved by technology

[0003] The inventors have found that at least the following problems exist in the prior art: due to the frequent conflicts between pedestrians and motor vehicles, the participants generally used in the current automatic driving simulation tests for conflict scenarios between people and vehicles are dummies or created in simulation software. Therefore, only simple human-vehicle conflict scenarios can be tested, which cannot meet the test requirements of autonomous driving.

Abstract

The embodiment of the invention discloses a test system and method based on an automatic driving vehicle in-the-loop pedestrian-vehicle conflict scene. The system comprises a simulation industrial control computer, positioning sensing equipment and an automatic driving algorithm industrial personal computer; the simulation industrial control computer transmits vehicle state information to positioning sensing equipment; the positioning sensing equipment used for sending acquired participant state information to the simulation industrial personal computer; the simulation industrial personal computer is also used for transmitting the updated simulation sensor signal of a virtual vehicle in a virtual test scene to the automatic driving algorithm industrial personal computer; the automatic driving algorithm industrial personal computer is used for sending a control signal to a test vehicle and transmitting the state information of the vehicle which has moved to the simulation industrial personal computer; and the simulation industrial personal computer is used for obtaining a man-vehicle conflict result and carrying out an automatic driving performance test according to the man-vehicleconflict result. A human-vehicle conflict scene test is carried out by acquiring the state information of a real participant and the state information of the test vehicle, so that the test scene is more real and abundant, and the test requirement of automatic driving is met.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle traffic, and in particular to a test system and method based on a scene of human-vehicle conflict in an autonomous driving vehicle. Background technique [0002] The vehicle-in-the-loop test is based on the test and certification of intelligent networked vehicles based on traffic scenarios, which fundamentally changes the research and development process, methods and standards of traditional vehicles. The simulation test is a basic test method to speed up the development of intelligent networked vehicle function prototypes, and is one of the important means to accumulate the test mileage of unmanned vehicles, which can effectively test dangerous or uncommon driving scenarios. [0003] The inventors have found that at least the following problems exist in the prior art: due to the frequent conflicts between pedestrians and motor vehicles, the participants generally used in the...
