Abstract: Example vehicle test methods and apparatus are described. In one example, first position information is obtained, where the first position information is position information of the vehicle. Second position information is obtained based on the first position information, where the second position information is position information of the vehicle in a simulation scenario. When obtaining the second position information, a position conversion relationship is obtained based on the first position information and simulation scenario information, and the second position information is obtained based on the first position information and the position conversion relationship.

Abstract: A simulation traffic scenario file generation method includes obtaining drive test data, where the drive test data includes traffic scenario data collected when an autonomous vehicle performs a driving test on a real road; determining a first moment at which the autonomous vehicle enters a first driving state or generates a request for entering the first driving state during the driving test; determining first clip data from the drive test data based on the first moment and ego vehicle information of the autonomous vehicle during the driving test; and generating a description file of a simulation traffic scenario based on at least the first clip data.
