Description

Technical field [0001] The present invention relates to the field of automobile technology, in particular to a method, platform and storage medium for verifying the expected functional safety of an automatic driving algorithm. Background technique [0002] Autonomous vehicle simulation testing and verification is an indispensable process in the entire system development process. Compared with traditional auto-driving cars, simulation, testing, and verification methods are more important. Because the autonomous driving system cannot fully identify and effectively deal with the complexity of the environment, only through a large number of simulations and tests to find problems, and to optimize and solve the problems found, can the mass production and listing of autonomous vehicles be promoted. [0003] At present, some research institutes have proposed test and verification schemes for autonomous driving. Among them, the upper-level autonomous driving virtual environment uses the co...
