Verification of ISO 26262 Software requirements in safety critical EE-systems (VISEE)

Purpose and goal

The project had the high level goals to: 1) Establish ISO26262 requirements validation by providing statistical evidence for assessment of safety goals of the complete electrical system. 2) Improve efficiency of development and verification of active safety systems by guidelines and methodology for verification complementing the ISO 26262 by describing how to efficiently combine simulation and testing. Both goals have been achieved by the development of new engineering methods and calibration of industrially validated mathematical models for defect predictions.

Expected results and effects

The project resulted in: - Development of two verification methods for better testing of software - Fault Bypass Modelling and a combination of fault injection and mutation testing - Identification of optimal parameters for mathematical models for defect inflow predictions and their distribution over time. - Development of measurement systems for predicting defects in automotive software development projects Books and scientific results leading to increased competence in the automotive software engineering community

Planned approach and implementation

The VISEE project was organized in 6 months long sprints where the work was planned and executed iteratively. The iterative organization allowed us to align the research work with the projects at the partner company. We could also adjust the planning based on the current status of the in-kind projects. Thanks to the close collaboration with Volvo Car Group, we could achieve results which can be used in car projects. Thanks to the collaboration with other projects, like the Software Center project, we had the opportunity to validate the results in more companies.
