Optimization of the development process of intelligent transportation systems using automotive SPICE and ISO 26262

Intelligent transportation systems (ITS) require the extension of the systems engineering approach to a higher abstraction level. Up to now, vehicles could be considered as closed systems while in future they have to be seen as components of an open system with ad hoc interfaces. Since ITS have reached the series development and production of single vehicles, standards of process quality and functional safety apply for this higher level as well. The paper discusses the impact of those standards to the design of ITS and the role of model-based software as a means for process quality and functional safety assurance. It emphasizes on the mutual synergies between process capability standards, functional safety, model-based development and design for variability.
