Abstract:

In order to speed up the development and verification of automatic driving function, a test and evaluation method of intelligent vehicle based on digital twin is proposed. Through the digital twin test technology, that is, the real vehicle drives in the real test field and effectively maps and combines with the virtual test environment, the test and verification environment of intelligent vehicle is greatly enriched, with the test efficiency improved and the test cost reduced. Combining real test vehicles and simulation test tools,this paper builds a digital twin autopilot test platform to realize the verification, test and evaluation of the algorithm, and also gives the corresponding case analysis. The rapid application of intelligent vehicle digital twin test and evaluation technology plays a positive role in accelerating the development and promotion of autonomous vehicles.
