Title:
AUTONOMOUS DRIVING TEST SYSTEM AND METHOD BASED ON DIGITAL TWIN CLOUD CONTROL PLATFORM
Document Type and Number:
WIPO Patent Application WO/2023/207016
Kind Code:
A1
Abstract:
An autonomous driving test system and method based on a digital twin cloud control platform. A high-fidelity virtual scene, which needs to be developed and tested, is generated by means of simulation software, and a plurality of virtual sensor models are established in the simulation software; information of a target object that is detected by a virtual sensor is input into an autonomous driving controller on a real vehicle by means of a bus, and information fusion and control decision are performed; and the controller sends decided acceleration, braking and steering instructions to a real-vehicle actuator. The real vehicle feeds vehicle motion state information on a vehicle bus back to the virtual scene, so as to complete synchronization of vehicle positions, closed-loop real-time testing and verification of the entire system are realized, and a scene-related twin effect is displayed in real time by means of the digital twin cloud control platform. Therefore, an integration test related to virtuality and reality combined autonomous driving algorithm function verification, a scene simulation test and a vehicle is realized, and the defects of existing real-vehicle road tests and software simulation testing technology are overcome, such that the test efficiency is improved.
