  18. Agenda • Introduction of AT & CE Demonstrators • HEV Powertrain Use Case • AUTOSAR BSW Use Case • Construction Equipment Evaluation • Open Discussion

  19. Background of AUTOSAR BSW module Use Case • There are four task identified in the use case • One task is completely allocated to Akhela • The other three are incremental in nature, i.e. the tools, methods and results are reused in the next task. • Therefore we can concentrate on “Validity of safety certification when moving BSW to different contexts” (first task) to ascertain status.

  20. Status of AUTOSAR BSW module Use Case • “Validity of safety certification when moving BSW to different contexts” contains • Tool used and developed is SaftyADD • Eclipse plugin attaches currently empty safety contract container to source code. • Method used is Safety Contracts from component model • Currently main focus, investigating the appearance, rules and content of the safety contract container • BSW module to be analyzed is AUTOSAR diagnostics • Source code candidate identified

  21. Status of SafetyADD tool AUTOSAR BSW module Use Case • Schematic view of SafetyADD Focus now is on formulation of the rule set governing the automatic compliance check of assume and guarantee to be implemented in the tool SafetyADD

  22. Status of SafetyADD tool AUTOSAR BSW module Use Case • SafetyADD When the development and testing of a SWC is done, it is time to export the software component for possible reuse at a later time. (stored in CAR) This is a view of the general properties of the SWC that can be edited

  23. Status of tool AUTOSAR BSW module Use Case (Akhela) Akhela uses Parasoft C++ Test that supports some default standard coding rules (i.e. MISRA C or C++) And also map AUTOSAR BSW requirements mapped onto ISO26262, with custom made rules for checking

  24. CTF & CAR useage in AUTOSAR BSW module Use Case • CTF interaction minimal, launchable from platform only. • CAR will hopefully enable storage and traceability of the certification artifacts and their dependencies. • The SafetyADD tool relates each software component to a component certificate via a contract; these contracts are in in the form of rules implemented in XML format not yet integrated in CAR.

  25. Open issues of AUTOSAR BSW module Use Case • How and when will Safety Contracts be integrated in CAR • A wider cooperation/discussion of practical usage of Safety Contracts

  26. Agenda • Introduction of AT & CE Demonstrators • HEV Powertrain Use Case • AUTOSAR BSW Use Case • Construction Equipment Evaluation • Open Discussion

  27. Status of Volvo CE Use Case - Background • The Volvo CE Use case consists of four incremental parts • Product development according to ISO 26262 process following • Concept Phase • Product development at System level • Product development at Hardware level • Product development at Software level • Development of a Component model concept including Safety Contracts and Safety Element out of Context • Development of a Product line concept on top of the Component model

  28. Status of Volvo CE Use Case – Current Status • The Volvo CE Use case consists of four incremental parts • Product development according to ISO 26262 process following • Concept Phase • Product development at System level • Product development at Hardware level • Product development at Software level • Development of a Component model concept including Safety Contracts and Safety Element out of Context • Development of a Product line concept on top of the Component model Ended Q2 2013 Ending Q3 2013 Background task (Q3) Starting
