PROBLEM TO BE SOLVED: To provide an electronic key detection system which achieves a search of an electronic key for executing two-way communication with on-vehicle equipment while reducing a wasteful cost, using a device other than the on-vehicle equipment.SOLUTION: The electronic key system includes: a smart phone 3 which executes an application 33 acquired from the outside of self-equipment; and terminal radio equipment 4 connectable to the smart phone 3. The terminal radio equipment 4 executes two-way communication between itself and an electronic key which returns a response signal when receiving a request signal transmitted from the on-vehicle equipment loaded on a vehicle. The application 33 causes a mobile telephone to execute request transmission processing for transmitting a request signal from the terminal radio equipment 4 connected to the smart phone 3, and notification processing for notifying presence of the electronic key on the basis of the response signal received from the electronic key by the terminal radio equipment 4 connected to the mobile telephone.SELECTED DRAWING: Figure 4
【課題】車載機との間で双方向通信を行う電子キーの探索を、車載機以外の装置を用いながら無駄なコストを減らして実現する電子キー検出システムを提供する。【解決手段】自機器の外部から取得したアプリケーション33を実行するスマートフォン3と、スマートフォン3に接続できる端末無線機4とを含む。端末無線機4は、車両に搭載された車載機から送信されるリクエスト信号を受信した場合に応答信号を返信する電子キーとの間で双方向通信を行う。アプリケーション33は、スマートフォン3に接続した端末無線機4からリクエスト信号を送信させるリクエスト送信処理及び携帯電話機に接続した端末無線機4が電子キーから受信する応答信号をもとに電子キーの存在を報知させる報知処理を、携帯電話機で実行させる。【選択図】図4
