Intelligent networked automobile complex test scene implementation system based on digital twinning

Abstract

The invention discloses an intelligent networked automobile complex test scene implementation system based on digital twinning. The system comprises a cloud control system, a real world and a virtualworld, the real world and the virtual world are in interactive connection, the real world comprises a real road, a tested vehicle running on the real road and a dynamic traffic element, the virtual world comprises a twin road, and the cloud control system comprises a dynamic updating module; the system comprises the steps of determining a required dynamic traffic element and a target motion trackthereof based on the twin road and the test scene; taking the target motion trail of the dynamic traffic element as a control target, and respectively generating a tested vehicle control instruction and a dynamic traffic element control instruction through coordination control calculation based on the real-time state of the tested vehicle and the real-time state of the dynamic traffic element output by the dynamic updating module; according to the invention, a complex test scene can be rapidly and efficiently realized, the test efficiency is improved, the whole realization process of the testscene is controlled with high precision, the repeatability of the test scene is good, and the test level is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic driving testing, and in particular relates to a complex testing scene realization system for intelligent networked vehicles based on digital twins. Background technique [0002] The road test of autonomous driving is an important link to determine whether automatic driving can be truly applied. Among them, due to the high safety, repeatability and small external interference of the closed road test, it is a necessary link before the road test of the automatic driving vehicle. . [0003] The dynamic traffic elements in the current closed road test mainly include: pedestrians, bicycles, motor vehicles, etc. In order to ensure the safety and reliability of the test, dummy people and cars are usually used for scene testing. Specifically, the dummy and dummy car are installed on a movable platform, and the control methods of platform movement generally include: First, manual control: the dummy and d...
