  1. 1. Postural and Muscular Responses of Car Occupants under Pre-Crash Conditions

    Författare :Ghazaleh Ghaffari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; vehicle occupant kinematics; pre-crash; evasive maneuvers; lane change; human body model; pre‐pretensioner belt; principal component analysis; linear mixed model;

    Sammanfattning : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems require comprehensive research on how vehicle occupants respond to these systems. The aim of this thesis is to provide insights into car passengers’ body kinematics and muscle activations in representative pre-crash circumstances with respect to two belt configurations (i.

    Sammanfattning : As the vehicle fleet becomes more equipped with crash avoidance systems, the proportion of crashes preceded by evasive manoeuvres is expected to increase. In an evasive manoeuvre, occupant position and posture can be influenced by the induced loading. Therefore, there is a need to predict the occupant response from evasive manoeuvres. LÄS MER

  5. 4. Pre-Crash and In-Crash Car Occupant Safety Assessment

    Författare :Alexandros Leledakis; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crash Configurations; Advanced Driver Assistance Systems ADAS ; Human Body Model; Crashworthiness; Intersection crashes; Occupant postures; Real-world safety;

    Sammanfattning : Tens of millions are annually injured in Road Traffic Accidents (RTAs) worldwide, while the estimated number of RTA fatalities amounted to 1.35 million in 2016. In Europe, car occupants hold the largest share (48%) of fatalities among all road users. The high fatality and injury numbers motivate the work of enhancing road traffic safety. LÄS MER

  7. 5. Passenger kinematics in evasive maneuvers

    Författare :Emma Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volunteer kinematics; Active Human Body Model; pre-crash; active muscles; occupant variability; evasive maneuvers;

    Sammanfattning : In situations that might lead to a vehicle crash, drivers often perform an evasive maneuver, such as braking or steering, in an attempt to avoid a crash. If a crash was not avoided, the maneuver could influence the injury outcome by altering the occupant’s position. LÄS MER
