Abstract

La présente invention concerne un procédé de prévention d'accidents de motocyclette par collision et un dispositif de casque associé. Le dispositif de casque a une alimentation en énergie assurée par un module de cellule solaire. De plus, le dispositif de casque est doté d'une unité de caméra montée sur une partie frontale du dispositif de casque dans le but de prendre une image en début de parcours, reçoit un signal détecté d'un capteur de chocs afin d'obtenir une valeur de choc et, si la valeur de choc est supérieure à la valeur-seuil de choc, il met en marche l'unité d'airbag de cou. En outre, le dispositif de casque calcule, en fonction de la réception d'un signal d'écho d'un capteur d'ultrasons, la distance jusqu'au véhicule derrière la motocyclette, en fonction du signal d'écho, et commande une action de déclenchement d'alarme basée sur la distance calculée.
