  1. 1. Computational Verification Methods for Automotive Safety Systems

    Författare :Jonas Nilsson; [2014]

    Sammanfattning : This thesis considers computational methods for analysis and verification of the class of automotive safety systems which support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents. Verification of these systems poses a major challenge, since system decisions are based on remote sensing of the surrounding environment and incorrect decisions are only rarely accepted by the driver.

  2. 2. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Carl Fredrik Larsson; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire; thermal runaway; gas emission; gas explosion; propagation; safety; abuse testing; Lithium-ion; cell case explosion; hydrogen fluoride;

    Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.

  3. 3. Decision Analysis in Fire Safety Engineering - Analysing Investments in Fire Safety

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Henrik Tehler; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Safety technology; Byggnadsteknik; Building construction; investment appraisal; epistemic uncertainties; fire safety; Decision analysis; risk analysis; Säkerhetsteknik;

    Sammanfattning : The application of decision analytical methods to the evaluation of investments in fire safety was investigated, particularly with the aim of being able to suggest a method for analysing a specific investment in fire safety for a specific factory. Attention was directed above all at the handling of cases of large epistemic uncertainty regarding both probabilities and utilities, Bayesian decision theory serving as a basis for the development of the method.

  4. 4. On Performance Evaluation of Automotive Active Safety Systems

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Jonas Nilsson; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Semi-Autonomous Vehicles; Active Safety; Automotive; Augmented Reality.; Verification; Performance Evaluation; Decision Making;

    Sammanfattning : Road traffic accidents are a major global problem, annually causing over 1.2 million fatalities. To improve road safety, active safety systems support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents.
