Electronic key system, and lock-side terminal and portable terminal employed in the same

Abstract

Provided is an electronic key system, comprising a lock-side terminal installed in a lock item which generates an electronic key with which it is possible to carry out at least locking and unlocking of the lock item; and a portable terminal which is capable of carrying out a transmission and receiving of the electronic key with the lock-side terminal which is installed in the lock item and other portable terminals. Upon receiving a request from one portable terminal, the lock-side terminal randomly generates the electronic key, and transmits the randomly generated electronic key to the one portable terminal. It is thus possible, without needing to provide a physical key, card, portable terminal, etc., to provide only an electronic key function to another person (either transferring or copying), to call a person in a distant location to operate on the lock item, etc., which is highly useful.

Description

Technical field [0001] The present invention relates to an electronic key system capable of unlocking doors and the like without inserting a key. Background technique [0002] In recent years, in electric vehicles and other vehicles, electronic keys have gradually become standard equipment. The electronic key does not even need to press the button for opening and closing the car lock like the remote control. As long as you approach the vehicle or touch the door handle, you can open the door lock, or you can just press the start button without inserting the key when entering the vehicle. Start the engine. [0003] For example, in Patent Document 1, an electronic key is used in a car rental system. This technology sends an electronic key from the center to the mobile terminal when the lease contract is concluded. The electronic key is valid for the reserved time and can lock and unlock the leased vehicle and start the engine. [0004] In addition, for example, Patent Document 2 disc...

AI Technical Summary

Problems solved by technology

[0012] However, in the existing electronic key system, only the mobile terminal that has acquired the electronic key can operate the rental vehicle, so there is a problem that, for example, the owner of the mobile terminal, that is, the reservation person, cannot return it due to an emergency or the like. , unless the mobile terminal of the person who made the reservation is handed over to the person who wants to operate it on his behalf, the operation cannot be performed
