However, software architecture is subject to a continuous shift of requirements and boundary conditions. At the same time, process standards ensure necessary quality but also cause a dramatic increase of the SW development effort. There exists a methodical gap between process and market requirements on one hand and reusable standardized software functions with a high quality on the other. In this paper, an approach is presented that aims for the continuous extension of powertrain control software with increasing quality based on existing boundary conditions and a consequent methodical extension of existing technical concepts. We address this by the development of a sustainable software architecture which enables the safeguarding of consistent design principles and thus higher development efficiency. Moreover, it opens the door to a comprehensive quality assurance concept based on the agile software development principle Continuous Integration. Finally, the feasibility of this approach and software quality assessment results are shown by the application for a gasoline engine in the vehicle.展开更多
