Scenario-based development and test processes are a promising approach for verifying and validating automated driving functions. [] Key Method At the same time, constraints regarding the selection and combination of parameter values are documented for the following process steps (e. g. evolutionary or stochastic test methods). As a second step, the parameter space representation is converted into data formats required by the simulation environment. As an example, the authors use scenarios on German freeways…

Scenario Description Language for Automated Driving Systems: A Two Level Abstraction Approach

A two-level abstraction approach to scenario description language (SDL) – SDL level 1 and SDL level 2 – which enables the exchange of scenarios between diverse stakeholders with varied usage requirements is proposed.

Translating Automated Vehicle Test Scenario Specifications Between Scenario Languages: Learnings and Challenges

This article provides a methodology and tool for translating scenarios in W MG-SDL to OpenX equivalents and discusses how different syntactic elements in WMG- SDL are translated into OpenX and associated challenges.

Writing Accessible and Correct Test Scenarios for Automated Driving Systems

A human-readable, natural language SDL is introduced, replacing the former Level-1 SDL, and complementing the more detailed Level-2 SDL, which is now syntax aligned with the ODD Taxonomy defined in ISO 34503.

Toward a Consistent Taxonomy for Scenario-Based Development and Test Approaches for Automated Vehicles: A Proposal for a Structuring Framework, a Basic Vocabulary, and Its Application

A basic vocabulary is proposed by identifying and describing terms that are particularly relevant to an overview of scenario-based development and test approaches and the relationships between them are illustrated as UML diagrams.

Using Ontologies for the Formalization and Recognition of Criticality for Automated Driving

This paper demonstrates ontologies to be a powerful tool for modeling and formalization of and reasoning about factors associated with criticality in the environment of automated vehicles, and leverages the well-known 6-Layer Model to create a formal representation of the environmental context.

Literature Review to Collect Conceptual Variables of Scenario Methods for Establishing a Conceptual Scenario Framework

This study introduces scenario variables (SVs) that represent constructs/semantics of scenario descriptions, according to 4 levels of constructs of a scenario method, and evaluates the comprehensibility and applicability of the defined variables.

Fundamental Considerations around Scenario-Based Testing for Automated Driving

This work sketches a generic framework around scenario-based testing and analyzes contemporary approaches to the individual steps, describing its function, proposed approaches and solutions, and identifying the underlying arguments, principles and assumptions.

Toward Generating Sufficiently Valid Test Case Results: A Method for Systematically Assigning Test Cases to Test Bench Configurations in a Scenario-Based Test Approach for Automated Vehicles

This work proposes and illustrates a method for systematically assigning test cases to test bench configurations in a scenario-based test approach for automated vehicles that allows for the effective and efficient execution of a large number of test cases while generating sufficiently valid test case results.

Synthesizing Traffic Scenarios from Formal Specifications for Testing Automated Vehicles

This work presents an optimization-based approach to synthesize scenarios only from formal specifications and a given map to concretize the specifications and formulate predicates, which are subsequently converted to a mixed-integer quadratic optimization problem.
