Road vehicles — Test scenarios for automated driving systems — Scenario evaluation and test case generation

Scope

This document defines a methodology to evaluate scenarios and provides a procedure extending test scenarios to test cases for a given function in a traceable way based on the testability. This document also defines necessary characteristics of a test case that include but not limited to unified identifier, test objective, inputs, steps, platform and expected results. This document describes methods and criteria to evaluate the test case (e.g., frequency, criticality, complexity of scenario) the coverage concerning functional and technical requirements, operational domain (OD) and test criteria, and also optimizing of the set of prioritizied test cases.  This document is applicable to Level 3 and higher ADS as defined in ISO/SAE 22736. The focus of this document is on safety (Functional Safety and Safety of the intended functionality (SOTIF)), in general the content is also applicable to non-safety relevant test scenarios.
