Simulation Traffic Scenario File Generation Method and Apparatus - A simplified explanation of the abstract

This abstract first appeared for US patent application 18303856 titled 'Simulation Traffic Scenario File Generation Method and Apparatus

Simplified Explanation

The patent application describes a method for generating simulation traffic scenario files using drive test data collected from an autonomous vehicle during a real road test.

  • The drive test data includes information about the traffic scenarios encountered by the autonomous vehicle during the test.
  • The method involves determining the moment when the autonomous vehicle enters a specific driving state or requests to enter that state during the test.
  • Based on this moment and the information about the autonomous vehicle's own characteristics (ego vehicle information), specific data clips are extracted from the drive test data.
  • These data clips are then used to generate a description file that can be used for simulating traffic scenarios in a simulation environment.


Original Abstract Submitted

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.
