  1. 1. Active Muscle Responses in a Finite Element Human Body Model

    Author : Jonas Östh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedback control; autonomous braking; finite element; human body model; active muscle; posture maintenance; reflexive response;

    Abstract : The development of automotive safety systems is moving towards an integration of systems thatare active before and during an impact. Consequently, there is a need to make a combinedanalysis of both the pre-crash and the in-crash phases, which leads to new requirements forHuman Body Models (HBMs) that today are used for crash simulations.

  2. 2. Active and Physics-Based Human Pose Reconstruction

    Author : Erik Gärtner; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; human pose estimation; reinforcement learning; physics-based human pose estimation; active learning;

    Abstract : Perceiving humans is an important and complex problem within computervision. Its significance is derived from its numerous applications, suchas human-robot interaction, virtual reality, markerless motion capture,and human tracking for autonomous driving. The difficulty lies in thevariability in human appearance, physique, and plausible body poses. READ MORE

  3. 3. Volunteer Muscle Activity in Dynamic Events. Input Data for Human Body Models

    Author : Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emergency braking; ative human body model; multidirectional perturbations; EMG; occupant kinematics; seatbelt pre-tension; reflex; validation data;

    Abstract : Human body models (HBMs) are virtual human surrogates used to predict kinematic and injury responses during motor vehicle crashes. In recent years, active musculature has been incorporated into HBMs for enhanced biofidelity in simulated emergency scenarios, in particular low-severity crashes and pre-crash situations, where occupant responses are influenced by muscle tension.

  4. 4. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

    Author : Gustav M Markkula; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

    Abstract : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. READ MORE

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

    Author : Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
