Towards a Scenario Toolkit for Autonomous Systems

Abstract

Scenario-based approaches have recently been widely adopted in the automotive and aviation industries. They aim to define and manage the test cases in a better way, thereby significantly reducing the risks and defining the safety argument for the system. To improve and complement the safety conditions, the Operational Design Domain (OOD) defines the operational boundaries of a driving automation system to specify the scope of the safety case, represented by human and machinereadable languages. Many approaches and standards that involve the essential modelling and safety concepts have been introduced to represent scenario-based simulation. Some parts of these approaches were implemented as graphical tools, such as System Entity Structure (SES) and Pruned Entity Structure (PES) tools, which are based on ontology and its derived structure. However, an extensive implementation covering scenario modelling and management, ODD, and assessment is still missing. This paper proposes an adapted scenariobased approach based on related research, and implements it in a robust GUI tool called Operational Domain Modeling Environment (ODME). ODME is progressing to fill the gap and address the aforementioned limitations by covering the modelling functions and safety approaches in one comprehensive environment with a wide range of capabilities and features.
