Abstract

L'invention porte sur un dispositif et sur un procédé anti-détournement pour véhicule. Le dispositif comporte une unité de commutation pour commander une connexion et une déconnexion d'un réseau électrique du véhicule, une première unité de détection de signal, une seconde unité de détection de signal, une unité de retard temporel pour retarder le temps, une unité d'entrée de mot de passe pour entrer un mot de passe et une unité de commande préétablie avec un mot de passe. Ladite unité de commande émet un signal de commande après la détection de signaux d'une porte latérale et d'un bouton-poussoir de commutation par lesdites première et seconde unités de détection de signal, et ledit signal de commande commande ladite unité de commutation pour couper ledit réseau électrique après un retard temporel avec l'unité de retard temporel. Ladite unité de commande compare le mot de passe entré par ladite unité d'entrée de mot de passe avec le mot de passe préétabli, de telle sorte que ladite unité de commande connecte ledit réseau électrique par l'unité de commutation lorsque les deux mots de passe sont identiques. L'électricité et l'essence du véhicule peuvent être coupées automatiquement après un certain temps et le véhicule ne peut pas être redémarré par le simple actionnement de la porte latérale et/ou d'une lampe de véhicule. Le dispositif anti-détournement qui est de structure simple, est également sans danger et fiable.
