Method and device for generating test cases for autonomous vehicles
First Claim
1. A method for testing autonomous vehicles comprising:
- collecting data from vehicles participating in public road traffic;
analyzing the data to identify a plurality of classifications representative of driving situations and a frequency of occurrence of each of the driving situations;
generating a first set of real-world test cases from the analyzed data;
generating a second set of test cases using predefined system application cases;
performing a comparative analysis between the first set of real-world test cases and the second set of test cases to identify at least one test case from the first set that is comparable with at least one test case from the second set; and
merging the a least one test case from the first set with its comparable at least one test case from the second set to form a combined test case.

Abstract
Test cases for autonomous vehicles are generated automatically by using data which have been collected from vehicles participating in public road traffic. A test planning system for autonomous vehicle includes defined application cases for autonomous vehicles. The vehicles are configured to identify test cases with prediction analyzes of a reference catalog of driving situations and the defined application cases, and compare, via a comparative analyzes, the test cases and the defined application cases to compile an expanded set of test cases, wherein the expanded set of test cases are compared to the defined application cases to output a complete set of test cases. The system also includes a central database configured to query the complete set of test cases.
