Zusammenfassung

Already today, hardware and software versions of embedded automotive components frequently evolve, due to discontinued electronics or fixed software bugs. For example, the average release cycle for new software versions of a vehicle already in production is six months (Guissouma et al. 2018). With agile development methods, continuous integration efforts and over-the-air software updates, this frequency and the amplitude of system alternations is expected to increase. At the same time, relevant design decisions with respect to the electronic architecture as a whole are made in early stages of product design. This includes for example the range of features or the hardware topology.
Flexibility for alternations is thus left mostly to software design and is locally bounded. This is challenging, especially for integration activities in late design phases or updates after start of production.
