  1. 11. A Method to Identify Future Potential of Vehicle Safety Technology

    Författare :Johan Strandroth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; future crashes; collision avoidance; evaluation; autonomous braking; Delta-v; active safety; vehicle safety technology; CPR;

    Sammanfattning : In the design of a safe road transport system there is a need to better understand the safety challenges lying ahead. One way of doing that is to evaluate safety technology with retrospective analysis of real world crashes. However, by using retrospective data there is the risk of adapting safety innovations to scenarios irrelevant in the future. LÄS MER

  2. 12. Tracking Theory for Preventive Safety Systems

    Författare :Lars Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Sammanfattning : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. LÄS MER

  3. 13. Computational Verification Methods for Automotive Safety Systems

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

    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.

  4. 14. Power System Oscillations - Detection, Estimation and Control

    Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER

  5. 15. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

    Författare :Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
    Nyckelord :Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.
