The complexity of embedded automotive systems calls for a more rigorous approach to system development compared to current state of practice. A critical issue is the management of the engineering information that defines the embedded system. Development time, cost efficiency, quality and dependability all benefit from appropriate information management.(More)
The automotive industry has a growing demand for the seamless integration of safety analysis tools into the model-based development toolchain for embedded systems. This requires translating concepts of the automotive domain to the safety domain. We automate such a translation between the automotive architecture description language EAST-ADL2 and the safety(More)
This paper describes and demonstrates an approach that promises to bridge the gap between model-based systems engineering and the safety process of automotive embedded systems. The basis for this is the integration of safety analysis techniques, a method for developing and managing Safety Cases, and a systematic approach to model-based engineering – the(More)
In this paper, we describe a concept for the automatic allocation of general Safety Integrity Levels (SILs) to subsystems and components of complex hierarchical networked architectures that deliver sets of safety critical functions. The concept is generic and can be adapted to facilitate the safety engineering approach defined in several standards that(More)
This paper proposes a vehicular control system architecture that supports self-configuration. The architecture is based on dynamic mapping of processes and services to resources to meet the challenges of future demanding use-scenarios in which systems must be flexible to exhibit context-aware behaviour and to permit customization. The architecture comprises(More)
Component based and model based development (CBD vs. MBD), in their various interpretations, are in focus in many efforts in order to better handle the efficient development of increasingly complex embedded systems. We elaborate on what CBD and MBD represent, on their differences and similarities. Although CBD represents a bottom-up approach whereas MBD is(More)
— The configurations of current automotive embedded systems are normally fixed during the development process and remain static over the vehicle lifetime. Future scenarios, however, call for more flexible configuration support. DySCAS (Dynamically Self-Configuring Automotive Systems) project aims to introduce context-awareness and self-management into(More)
For systems where functions are distributed but share support for computation, communication, environment sensing and actuation, it is essential to understand how such functions can affect each other. Preliminary Hazard Analysis (PHA) is the task through which safety requirements are established. This is usually a document-based process where each system(More)
