Towards Conceptually Elevating Modern Concepts of Operational Design Domains and Implications for Operating in Unstructured Environments

Abstract. This paper explores the basic concepts of Operational Design Domains (ODDs) in the field of autonomous driving. We address the intricacies of different scenario descriptions and promote the communication of system requirements and operational constraints in the context of Automated Driving Systems (ADSs). Ongoing standardization efforts highlight the recognition of the importance of ODDs as a tool to manage the complexity of an ADS in accurately defining operational boundaries and conditions, particularly in structured environments. In line with this, our work explores the conceptual integration of multiple ODDs within an ADS to enable operation across different domains. Drawing on the existing literature on ODD extension concepts and leveraging insights from our research efforts, we strive for exemplary adaptation of operations in unstructured environments such as hybrid mines. A key focus is the translation of a solution that has been successfully tested in the context of hybrid mines and structured terrain into modern ODD frameworks. In particular, we focus on taxonomy as a fundamental element of an ODD framework. Through comparative analysis and evaluation of existing taxonomies, we aim to provide insights into the configuration of ODDs for both structured and unstructured environments, thereby contributing to their broader implementation in the dynamic landscape of autonomous driving technologies.
