Purpose and goal

The objective has been to propose method and tools for requirements decomposition of safety-critical functions in the electrical system. Furthermore, the method must meet ISO26262 and contribute to more efficient development. The objective has been met to a large extent. Both method and prototype tools have been developed. The knowledge has been described in articles and dissertation. Knowledge has been transferred to Swedish industry through presentations in national conferences, and further through direct impact of the new methods now being developed at Scania.

Expected results and effects

Overall, the project has been very successful in that project objectives have been achieved and that the research results also have had a strong impact on Scania´s future methods and tools. This will greatly contribute to the company´s ability to effectively build future increasingly digitalized products such as autonomous vehicles. This contributes positively to Scania´s global competitiveness but also the position within the VW group. The project results have also influenced the content of the related MSc- and PhD courses at KTH.

Planned approach and implementation

The project has formalized requirements decomposition and focused on agile and lean development. The main deliverable is a contract-based approach to requirements decomposition. Studied aspects are: formalization of responsibilities between supplier and OEM; visualization of requirements decomposition with graphs; Safety Integrity Level associated with the contracts; formalization of software architectures; tool support for lean and agile development. The method has also, together with engineers, been applied to several parts of Scania´s electricity system.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
