However, no system has been shown to be efficient enough so far, notably because of the fact that arousal insufficiency manifests in different ways in different individuals, making it difficult to define a common reference system for detecting this phenomenon

Embodiment Construction

[0027] Said single figure is a diagrammatic representation of a device 10 intended to be arranged in a vehicle for predicting a driver's state of alertness. According to the configuration shown in the figure, the forecasting device 10 comprises a camera 11 provided for installation in a vehicle, oriented towards the driver and intended to capture video images of the driver of the vehicle, in particular the driver's position in the driving position. A video image of the part of the officer above his chest (notably, including his head). The camera 11 used is preferably a high-definition camera that continuously captures black and white images. Preferably, the field of view of the camera 11 is illuminated by several sources of infrared LED type 12 , synchronized with the HD camera and placed on either side of the camera 11 . These LEDs thus allow the camera to capture quality images while eliminating reflections in on-road driving situations and large contrast changes caused by ...

Abstract

The invention relates to a device for predicting (10) a vigilance level of a driver, comprising a camera (11) for acquiring images of said driver, an image processing module (13.1) for characterizing, from the acquired images, physiological data of said driver, means for storing profiles of the change in electro-encephalographic and physiological data of a set of standard drivers, acquired in a synchronized manner in the course of driving tests during a calibration phase, and a detection module (13.2) capable of comparing the change in physiological data of said driver with the stored profiles of the change in physiological data in order to determine at least one profile satisfying resemblance criteria and performing a statistical prediction of the change in the vigilance level of said driver from the analysis of the stored profile of electro-encephalographic data corresponding to the profile of changes in physiological data having satisfied the resemblance criteria.

Description

technical field [0001] The present invention relates to an apparatus and method for predicting the alertness level of a driver of a motor vehicle. Background technique [0002] Application of the method according to the invention aims in particular at avoiding driver hypovigilance. Arousal insufficiency usually corresponds to the transition between wakefulness and sleep, during which the body senses a drastic reduction in its ability to observe and analyze. This reduced level of alertness caused by the involuntary transition from the waking state to the sleeping state is the cause of many accidents on the road. Therefore, it appears crucial to be able to detect and prevent such dangerous states of the driver in order to increase his safety. [0003] Thus, to maintain a level of alertness and wakefulness commensurate with driving activity, drivers must consider their driving time and take regular breaks, usually every two hours are recommended. However, this requirement is...
