More Information
Summary:Provided is an electronic key system capable of improving security against vehicle theft. A smart ECU (1) takes in encryption information from an electronic key (50). When all encryption information stored in a memory (11a) and a memory (33c) of a connector (3) with built-in electronic components and encryption information transmitted from the electronic key (50) match, the smart ECU (1) releases security and permits the operations of a door lock drive device (61), a steering lock drive device (62), and an engine control device (63). L'invention concerne un système de clé électronique permettant d'améliorer la sécurité en matière de vols de véhicule. Un ECU intelligent (1) reçoit des informations de cryptage d'une clé électronique (50). Lorsque toutes les informations de cryptage stockées dans une mémoire (11a) et une mémoire (33c) d'un connecteur (3) comprenant des composants électroniques intégrés et les informations de cryptage transmises par la clé électronique (50) correspondent, l'ECU intelligent (1) lève la sécurité et permet l'actionnement d'un dispositif de commande de serrure de porte (61), d'un dispositif de commande d'antivol sur la direction (62) et d'un dispositif de commande de moteur (63).
