Abstract

Scenario-based testing is a promising approach to assess and assure the safety of automated and connected driving functions. In this approach, test scenarios are often described in an abstract way. Norms sometimes even provide certain parameter values for, e.g., approaching maneuvers in lane-keeping situations. However, the type of parametrization is often not fully specified - neither in databases nor in regulations. This paper assesses differences in possible types of parametrizations for test scenarios and gives guidance about the importance to choose a suitable parametrization for individual use cases. For this, different parametrization types are categorized. The effects on the outcome of tests are investigated in a comprehensive study simulating 435,456 test cases in the CARLA simulator. Thereby, 8 different systems under test are investigated to observe the outcome on different parametrizations on intersections. The results show a high influence of the parametrizations for different systems under test on the test outcomes leading to the need for carefully selecting a suitable parametrization approach.
