From AUTOSAR Models to Co-simulation for MiL-Testing in the Automotive Domain

Models in testing are important for describing, understanding, and managing tests. In the automotive domain, AUTOSAR is an important standard to model components of electronic control units. AUTOSAR, however, lacks information about tests or test scenarios. Early testing in the automotive domain is often done by Model-in-the-Loop simulation. Simulations of several components are run in different environments, each. Thus, they need to be connected (co-simulated) for integration testing of these components, e.g., via simulator coupling. This paper is focused on closing the gap between AUTOSAR models and co-simulation-based test scenarios that use simulator coupling. Our main contribution is the definition of a modeling language to describe test environments. The instances of this language can be derived from existing AUTOSAR models and can also be used to automatically generate co-simulation-based test environments. Furthermore, we provide a workflow to integrate this model in the engineering process and an experiment report to demonstrate the applicability and the advantages of the approach.
