Collection of Requirements and Model-based Approach for Scenario Description

As the level of automation and variety of Advanced Driver Assistance Systems (ADAS) and Automated Driving (AD) increases, new challenges for Verification and Validation (V&V) methods emerge. This applies especially in urban areas due to the combination of many different environmental elements, participant types, and interactions between the participants. Scenario-based testing and resimulation of recorded data are promising approaches to tackle these new challenges. An elementary component of these methods is the scenario description, which serves as a connection between different working steps in the V&V workflow. This heterogeneous usage of the scenarios during the development and validation process leads to a multitude of different, sometimes contradictory, demands on the scenario description. Nevertheless, a uniform description is desirable for easy exchange and automation. The contribution of this paper is twofold: Firstly, the described versatile field of demands is systematically broken down to requirements for the scenario description languages. This step is essential to ensure broad applicability. Secondly, this paper introduces a holistic scenario description language that is usable for generation, extraction from real-world test drives and execution of the scenarios enabling an automated workflow and increased traceability between generated, extracted and reshnulated scenarios. The description and uses a model based approach and has been exemplarily tested for manually created scenarios and automatic resimulation of real-word test drives.
