Functional Integration of E/E Systems

The complexity of electrical/electronic vehicle systems mandates a systematic approach to the development of vehicle control, infotainment or comfort functions as well as the integration of these functions in an in-vehicle network consisting of several dedicated bus systems and according gateways. Due to reduced time-to-market, the integration has to be performed in a virtual environment. The classical Digital Mockup (DMU) addresses the physical integration of EE systems as mechanical components. However, functional aspects play a dominant role in EE vehicle systems. For this reason, functional integration defines a multi-view, mixed-level approach to the description, transformation, verification and integration of vehicle functions under consideration of the physical vehicle integration.
