  1. 1. Towards a human body model for prediction of vehicle occupant kinematics in omni-directional pre-crash events

    Författare :Emma Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pre-Crash Manoeuvres; Shoulder Muscle Control; Active Human Body Model;

    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

  3. 2. DREAM: A Method for Understanding the Causation of Single-Vehicle Crashes

    Författare :Jesper Sandin; Chalmers tekniska högskola; []
    Nyckelord :driver error; accident model; contributory factors; causation; single-vehicle crashes; case study; pre-crash; accident analysis;

    Sammanfattning : When conducting in-depth causation studies, it is essential that the analysis method can both define and classify contributing factors and be able to analyse how these factors may interact to produce a critical event. These issues are highly influenced by the underlying theory, e.g. the accident model. LÄS MER

  4. 3. Volunteer Kinematics and Muscle Activity in Dynamic Events Representative of Pre-crash Scenarios, Evaluation Data for Human Body Models

    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; volunteer; evasive manoeuvres; human body model; validation data; occupant kinematics; pre‐pretensioner belt; lane change; boundary conditions;

    Sammanfattning : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems involve comprehensive research on how vehicle occupants respond to these systems in pre-crash situations. Human Body Models (HBMs) are mathematical tools developed to predict human responses and injury outcomes in different pre-crash and in-crash situations. LÄS MER

  5. 4. Muscle Responses in Dynamic Events. Volunteer experiments and numerical modelling for the advancement of human body models for vehicle safety assessment

    Författare :Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-crash dynamics; spatial tuning patterns; occupant kinematics; electromyography.; Traffic safety; muscle activity; human body models;

    Sammanfattning : Fatalities and injuries to car occupants in motor vehicle crashes continue to be aserious global socio-economic issue. Advanced safety systems that provide improvedoccupant protection and crash mitigation have the potential to reduce this burden. LÄS MER

  7. 5. Child Passenger Kinematics in Emergency Manoeuvres

    Författare :Isabelle Stockman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : ABSTRACTIn motor vehicle impacts, a child’s head is generally the most frequently injured body region, irrespective of impact direction. Head to front seat back impact has been identified as a predominant cause of injury for rear seated, seat belt restrained children, aged 3 – 13, who sustained AIS2+ head injuries in frontal impacts.
