Scenario-Based Systems Engineering: An Approach Towards Automated Driving Function Development

摘要

In this contribution, we propose an approach for scenario-based systems engineering for automated driving functions. The growing complexity of future driving systems presents an enormous challenge for the development and testing processes, the validation and release procedure, as well as the organization of work. Accompanying, the end of development and the concerning effort is difficult to estimate. This often leads to postponements and rise of development costs. Furthermore, recent research activities show that established test methods such as statistical testing are not well suited for the validation/verification and the release process of automated driving functions. Thus, we propose a method for continuous usage of scenarios, embedded in the systems engineering process, to divide complex and intangible development goals in smaller solvable tasks. Furthermore, we suggest how scenarios can be used for validation and verification of the target system. In this approach, various artifacts are generated, which help to plan, organize, and trace the development and validation process. As a result, temporal expenditure and development costs get estimable. Moreover, the technical progress of the system-to-develop becomes apparent at an earlier point of time.
