Apport des simulations immersives pour l’étude du comportement dynamique des occupants d’un véhicule

Abstract : Whiplash remains a strong socio-economic issue in road accidents. Research in this field has led to the development of injury criteriathat are still difficult to validate for all situations. The hypotheses of this project are that head stabilization strategies are influenced by activities prior to thedynamic event as well as by certain cognitive availabilities. To answer this, this thesis experimented different dynamic environments and explored the use of virtual reality as a simulation tool for the study of the subject's dynamic behaviorand evaluated the relevance of these tools.A first experimentation allowed to show the importance of the alert in the subject by using an automatic emergency braking system of an equipped vehicle. A second study consisting in the replication of this experiment in a hexapod driving simulator was able to show that the subject's behaviorwas comparable despite the lower dynamic performance of the system. Finally, a last study carried out on accelerated subjects on a laboratory-controlled cart, whose emotional state was controlled, was able to account for the importance of the integration of physiological parameters in the study of head stabilization strategies in the subject.Immersive simulations proved to be relevant to control the subject's cognitive environment and the importance of the latter could be observed. The use of these technologies allows us to glimpse new experimental possibilities that can lead to a better understanding of the subject's stabilization strategies.
