ATESST 2 - Advancing Traffic Efficiency and Safety through Software Technology Phase 2


Advanced automotive functions are increasingly dependent on software and electronics. The complexity and criticality Advanced automotive functions are increasingly dependent on software and electronics. The complexity and criticality of automotive embedded systems already constitute an inhibiting factor for further evolution of functionality. This is evident for single automotive systems and even more so for functions that interact between vehicles and between vehicle and infrastructure, cooperative systems. New techniques and methodologies that support cost-efficient development, verification and validation (V&V), including efficient fieldoperational tests, are required to exploit the new opportunities.
ATESST2 will contribute to bridging the gap between cooperative systems and enabling design and verification technologies. The basis of the project is the architecture description language EAST-ADL2, developed in the ATESST project. The language provides an information structure and ontology that makes the development of stand-alone automotive embedded systems more systematic and predictable.
In ATESST2, the EAST-ADL2 modeling approach will be further extended and new results will be provided to support development and V&V of cooperative active safety systems. Expected end results include:

  • An architecture description language with improved means for capturing the requirements, characteristics and configurations of cooperative systems and the related analysis and V&V.
  • Methodology and guidelines supporting language/tool adoption and cost-efficient development and V&V, and
  • Harmonization of EAST-ADL2 with relevant standards including AUTOSAR and SysML.

The model-based development and V&V approach to be developed in ATESST2 contributes to improving Communication among system stakeholders, Documentation, and V&V capabilities. This is a shift from today's document-driven testing and simulation procedures, to a model-based way of working. This provides means for stakeholders to deal with the complexity and risk management of cooperative active safety systems.
