Electronic key system

Abstract

An electronic key system for a vehicle that prevents private information from being available to a third person. The electronic key system includes a terminal (43, 44, 45), electronic keys (10, 11, 12, 13), and a device (20, 33) having comparing and control components. Each electronic key stores a distinct identification code and transmits the identification code to the vehicle. At least one of the identification codes is a restriction code for restricting the usage of the terminal. The comparing component is arranged in the vehicle and stores verification codes associated with the identification codes. The comparing component retrieves the identification code of one of the electronic keys and compares the retrieved identification code with an associated one of the verification codes. The control component restricts activation of the terminal when the retrieved identification code is the restriction code.

Description

technical field [0001] The present invention relates to an electronic key system, which performs predetermined in-vehicle operations through wireless communication between the electronic key and the vehicle. Background technique [0002] In recent years, intelligent transportation systems (ITS) using information technology have been extended to reduce traffic obstacles, exhaust emissions, and automobile accidents. Examples of ITS are Advanced Navigable Highway System (AHS), which maintains an appropriate distance between vehicles and warns the driver when necessary, and Electronic Toll Control (ETC), which enables payment of tolls without stopping at toll booths road costs. Other examples of ITS are Vehicle Information and Communication System (VICS), which provides traffic information to drivers using a terminal installed in a car, such as a car navigation terminal, and Advanced Safety Vehicle (ASV), which drives a car automatically. [0003] In order to use ITS, various ...

AI Technical Summary

Problems solved by technology

Therefore, a third party may use the navigation system terminal without permission and registration, verification, editing, or standardization of personal information stored in the vehicle terminal

In addition, a third party may use an ETC terminal or an emergency call system terminal without obtaining permission and reviewing the use history

Therefore, it is difficult for the car owner to lend the key to a third party without worrying about how the key will be used when someone parks or repairs the car
