  1. 21. On the Design and Analysis of Consensus Protocols for Automotive Electronic Systems

    Författare :Negin Fathollah Nejad Asl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication Failures; Consensus; Distributed Algorithms; Automotive Systems; Probabilistic Analysis;

    Sammanfattning : This thesis deals with the fundamental problem of reaching agreement on a value in a distributedcomputing system in the presence of faults. We address this problem in the contextof safety-critical distributed automotive applications, such as virtual traffic lights. LÄS MER

  3. 22. On the Design of Electrical Architectures for Safety-Critical Automotive Systems

    Författare :Per Johannessen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed systems; system-safety; model-based development; hazard analysis; dependable systems; drive-by-wire; electrical architecture; time-triggered communication;

    Sammanfattning : Increasing demands in the automotive industry in areas such as safety, driving pleasure and environmental care require new complex functionality to be implemented in cars. This evolution will to a large extent depend on the introduction of drive-by-wire systems in cars. LÄS MER

  4. 23. Safety Analysis of Systems-of-Systems

    Författare :Stephan Baumgart; Joakim Fröberg; Sasikumar Punnekkat; Iain Bate; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Safety Analysis; Hazard Analysis; Model-based Development; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical systems may fail dangerously with severe consequences to the health of the involved humans, costly equipment, the environment, or other valuable assets of a stakeholder. For these classes of systems, the developers are obliged to analyze each potentially hazardous situation thoroughly. LÄS MER

  5. 24. On design of complex safety critical automotive systems : a semi-automated approach for balancing profit and safety

    Författare :Christian Grante; Matthew Cartmell; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Design processes for complex safety-critical systems in the automotive industry need to evolve in order to address increasing demands for integration of car functions over common networked infrastructures. New processes must address cost and safety concerns, and at the same time maximize profit. LÄS MER

  7. 25. On Fault Injection-Based Assessment of Safety-Critical Systems

    Författare :Daniel Skarin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transient Faults; Fault Injection; Error Detection and Recovery; Fault Tolerance; Embedded Control Systems;

    Sammanfattning : This thesis deals with techniques for designing and evaluating error detection and recovery mechanisms for computer systems. For the assessment of such systems, we describe a comprehensive fault injection tool that is capable of emulating the effects of hardware errors in microprocessors. LÄS MER
