Abstract

La présente invention concerne la détection d'un accident et les actions de commande d'urgence nécessaires pour un véhicule à deux roues. Un assistant numérique personnel (PDA) (3), qui est un smartphone ou une tablette PC, est pourvu d'un accéléromètre (4) et de capteurs de gyroscope (5) qui sont montés dans le véhicule. La détection de chute est déclenchée si l'angle d'inclinaison du véhicule dépasse un seuil lors de la détection de la rupture de panique et de l'état de fonctionnement du moteur. L'action d'urgence par le PDA (3) consiste à envoyer un SMS au contact d'urgence et un appel d'urgence au contact. Les informations envoyées par le PDA monté sur véhicule (3) contiennent des données de latitude et de longitude de l'emplacement du véhicule qui sont extraites du dispositif GPS (2) qui est intégré à l'intérieur du PDA (3). Le contact d'urgence peut entreprendre des actions immédiates pour sauver la vie du conducteur après l'accident. Ainsi, on augmente le facteur de sécurité du conducteur, pour tous les véhicules à deux roues.
