  1. 21. Controlling over-actuated road vehicles during failure conditions

    Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. LÄS MER

  3. 22. Dynamic speed adaptation based on information technology - a theoretical background

    Författare :Andras Varhelyi; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; driver acceptance; appropriate speeds; speed behaviour; critical conditions; Social sciences; Samhällsvetenskaper;

    Sammanfattning : Knowledge on the factors influencing driver speed-behaviour, the relationship between speed and traffic safety and means to influence speed behaviour is systematised. Expert judgements and the high proportion of injury accidents show that improved speed adaptation has the largest safety potential in the following situations: - Road surface-, visibility and weather affected situations (e.

  4. 23. Epidemiological aspects on pain in whiplash-associated disorders

    Författare :Lena Holm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neck injury; whiplash-associated disorders; traffic collision; psychosocial.;

    Sammanfattning : Introduction: Whiplash-associated disorders (WAD) are common after car collisions. Little is known about risk factors for onset of the injury or about factors influencing the recovery. Objective: The general objective of this thesis was to assess the influence of psychosocial factors on pain and disability in WAD. LÄS MER

  5. 24. On associations between different factors and whiplash injury

    Författare :Anita Berglund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Whiplash Injuries; Epidemiology; Traffic accidents; Cohort studies; Neck pain; Back pain; Risk factors; Prognosis.;

    Sammanfattning : The overall aim of this thesis was to evaluate associations between different factors and whiplash injury (defined as a soft tissue injury to the neck without fracture or dislocation), focusing on risk of initial and future complaints. The objectives in Paper 1 and II was to determine whether exposure to a rear-end collision, with or without whiplash injury, is associated with future neck or shoulder pain (Paper 1) and other health complaints, besides neck pain (Paper II).

  7. 25. Exploring Perceptions of Route Environments in Relation to Walking

    Författare :Dan Andersson; Peter Schantz; Lina Wahlgren; Eva Andersson; Maria Johansson; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Sammanfattning : Background: Every walk takes place in a route environment, which can play an important role in deterring or facilitating walking. The focus of this thesis is on the perceptions of environmental variables, and how they relate to appraisals of route environments as hindering – stimulating for walking and unsafe – safe for reasons of traffic, in two metropolitan environments.
