SHARING SYSTEM

To provide a sharing system which can secure the usability of a share object at an operation.SOLUTION: In a sharing system 21, user authentication by key authentication Dk is performed between a portable terminal 23 and a sharing device 24, and when the authentication is established, the sharing device 24 is transited to an authentication finish state (key-function on). The sharing device 24 is attached to a seatbelt of a vehicle 1, located in a communication area of an outdoor transmitter 16a before the boarding of a user, and located in a communication area of an indoor transmitter 16b immediately before a start of an operation. When an outdoor smart collation is established between the sharing device 24 which is transited to the authentication finish state and the sharing system in the communication area of the outdoor transmitter 16a, the lock/unlock of a vehicle door 13 is permitted or performed. Also, when an indoor smart collation is established between the sharing device 24 which is transited to the authentication finish state and the sharing system in the communication area of the indoor transmitter 16b, a transition operation of a vehicle power supply is permitted.SELECTED DRAWING: Figure 1 【課題】シェア対象物の操作時の利便性確保を可能にしたシェアリングシステムを提供する。【解決手段】シェアリングシステム２１は、携帯端末２３とシェアリング装置２４との間で鍵認証Ｄｋによるユーザ認証を実行させ、この認証が成立すればシェアリング装置２４が認証完了状態（キー機能オン）に移行させる。シェアリング装置２４は、車両１のシートベルトに取り付けられ、ユーザ乗車前、室外送信機１６ａの通信エリア内に位置し、運転開始直前、室内送信機１６ｂの通信エリア内に位置する。室外送信機１６ａの通信エリア内において、認証完了状態に移行したシェアリング装置２４との間で室外スマート照合が成立すれば、車両ドア１３の施解錠が許可又は実行される。また、室内送信機１６ｂの通信エリア内において、認証完了状態に移行したシェアリング装置２４との間で室内スマート照合が成立すれば、車両電源の遷移操作が許可される。【選択図】図１
