Abstract:
The automotive industry aspires a high degree of reuse in software development in order to reduce the development costs. The reuse is achieved by a product-wide development for different vehicle variants, as well as by reuse in subsequent products. However, the increasing complexity and degree of variability of automotive software systems hinders the capabilities for reusability and extensibility of these systems to an increasing degree. After several product generations, software erosion is growing steadily, resulting in an increasing effort of reusing software components, and planning of further development. Here, we give a holistic approach for a long-term manageable and plannable software product line architecture for automotive software systems. Furthermore, we consider automotive product development and prototyping based on software product lines, and propose an approach for architecture compliance checking to avoid software erosion. We demonstrate our methodology on a real world case study, a brake servo unit (BSU) software system from automotive software engineering.
