    Författare :Jonas Westman; Mattias Nyberg; Mats Heimdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contracts; Heterogeneous Systems; Safety; Architecture; Requirements; Specification; Elements; Compositional; IEC 61508; ISO 26262; Kontrakt; Heterogena System; Säkerhet; Arkitektur; Kravhantering; Specifiering; Element; Kompositionell; IEC 61508; ISO 26262; Machine Design; Maskinkonstruktion;

    Sammanfattning : Requirements engineering (RE) is a well-established practice that is also emphasized in safety standards such as IEC 61508 and ISO 26262. Safety standards advocate a particularly stringent RE where requirements must be structured in an hierarchical manner in accordance with the system architecture; at each level, requirements must be allocated to heterogeneous (SW, HW, mechanical, electrical, etc. LÄS MER

  4. 3. Impact of water contamination and system design on wet clutch tribological performance

    Författare :Nowshir Fatima; Amaya Igartua; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Wet clutches are lubricated machine components which utilize friction to transfer torque and thus establish connection between shafts rotating at different speeds. They are used in automatic transmission as shifting device or lockup clutch. LÄS MER

  5. 4. Model-Implemented Fault Injection for Robustness Assessment

    Författare :Rickard Svenningsson; Martin Törngren; Sasikumar Punnekkat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Injection; Model-Implemented Fault Injection; Robustness; Assessment; ISO 26262; ISO 61508; Software;

    Sammanfattning : The complexity of safety-related embedded computer systems is steadilyincreasing. Besides verifying that such systems implement the correct functionality, it is essential to verify that they also present an acceptable level of robustness. LÄS MER

  7. 5. On Hazard Identification and Safety Cases In the Automotive Domain

    Författare :Fredrik Törner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Safety Case; Hazard Analysis; Hazard Identification; Automotive;

    Sammanfattning : Since electronics is the enabling factor for functional growth in many automotive engineering areas, the electrical system of a vehicle is becoming increasingly important for every new vehicle generation. Many new functions implemented in electronics are safety related, which raises new requirements on how to ensure the safety of automotive electronic systems. LÄS MER
