Conception d'un dispositif pour la détection automatique des premières variations du niveau de vigilance du conducteur au volant de son véhicule : capteur non-contraignant et électronique associée

Abstract : At the present time, there is no strainless and reliable mean to automatically detect the first variations of vigilance- state of a vehicule driver. This study is based upon the determination of the physiological parameter (breathing rhythm regularity) to predict sleeping one or two minutes before it occurs. Tests in a leepinglaboratory have pointed out that the EEG activity, during the early sleeping phase is characterized by a breathing rhythm regularization. Besides, this study deals with aH associated electronics of the data acquisition and processing device to seize the signal of thoracic impedance criterions : sens or, useful signal and detection criterions. After that, this report presents the results of the validation tests of detection device and the tests in real condition.
