Modeling of Operational Aspects for the Autonomous Vehicle Development

The development of systems with highly automated or autonomous functions leads to high demands on the consideration of dependencies to external actors. In particular, the utilization phase of the systems must be considered closely, since the dynamic, operative context manifests itself only within utilization. Additionally, when considering involved sensors and actors for the utilization of functions of Advanced Driver Assistance Systems (ADAS) for commercial vehicles, a precise and clear communication between different stakeholders in vehicle development is essential. In Model-Based Systems Engineering (MBSE), this can be achieved by modeling so-called operational aspects. Operational aspects are model elements and their relationships to each other, which are represented in suitable views. In this contribution, modeling of operational aspects will be demonstrated exemplary on a case study related to the development of an Evasive Maneuver Assistant (EMA) for vehicles. Currently, modeling operational aspects is not common in the civil sector and therefore not always considered in the development phase of commercial vehicles.
