Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a verification method, platform and storage medium for the expected functional safety of an automatic driving algorithm. Background technique [0002] Self-driving vehicle simulation testing and verification is an indispensable process in the entire system development process, which is more important than the simulation, testing and verification methods of traditional automobile self-driving cars. Because the automatic driving system cannot fully identify and effectively deal with the complexity of the environment, only through a large number of simulations, tests to find problems, and optimize the solutions to the found problems can promote the mass production and launch of autonomous driving vehicles. [0003] At present, some scientific research institutes have proposed test and verification schemes for autonomous driving. Among them, the upper-level automatic driving vir...
