AI Technical Summary

Technical Problem

In the ring test of the self-driving real car, virtual traffic participants cannot fully accurately simulate the real situation and cannot accurately achieve the set test scenario.

Method used

By obtaining the real-time trajectory data of the vehicle to be tested, and generating the target trajectory information from the mobile device based on the preset test scenario configuration information, the mobile device carries the traffic participant model and moves it to the target test position to achieve the generation of in-ring test results.

Benefits of technology

The trajectory planning of the physical traffic participant model is realized, ensuring that the vehicle to be tested and the self-mobile device are in the target test position at the same time. The simulation system can accurately simulate complex test scenarios and improve test coverage.

Abstract

The invention is suitable for the technical field of vehicle testing, and provides a real vehicle in-the-loop testing method and device, terminal equipment and a storage medium, the method is applied to a simulation system, and the simulation system firstly obtains real-time track data of a to-be-tested vehicle; according to the real-time trajectory data of the to-be-tested vehicle and preset test scene configuration information, target trajectory information of a self-moving device is generated, the self-moving device carries a traffic participant model, and the target trajectory information is used for indicating the self-moving device to move to a target test position; and finally, after the to-be-tested vehicle and the self-moving device move to the target test position at the same time, generating an in-loop test result. Therefore, the self-moving device is scheduled based on the trajectory data, trajectory planning of the entity traffic participant model is achieved, finally, the to-be-tested vehicle and the self-moving device are both located at the target test position at the same moment, and then the simulation system can accurately simulate a complex test scene.
