PORTABLE TERMINAL DEVICE AND AUTHENTICATION SYSTEM
To provide an authentication system to allow communication using a high-frequency between a portable terminal device and in-vehicle equipment to be easily established.SOLUTION: A portable terminal device of an authentication system includes: a first communication unit to perform wireless communication with in-vehicle equipment mounted on a vehicle by using a first frequency band and a second communication unit to perform ultra-wide band wireless communication using a second frequency band including frequencies higher than the first frequency band; a notification unit to perform a predetermined notification operation; and a first controller to control the first communication unit, the second communication unit, and the notification unit. The first controller makes the first communication unit perform wireless communication for authentication with the in-vehicle equipment, and makes the second communication unit perform wireless communication for measuring a distance from the portable terminal device to the in-vehicle equipment, and makes the notification unit perform a predetermined notification operation when the first communication unit receives a radio signal from the in-vehicle equipment indicating that distance measurement fails.SELECTED DRAWING: Figure 1
【課題】携帯端末装置と車載機器との間で高周波を用いた通信を成立させやすい認証システムを提供する。【解決手段】認証システムの携帯端末装置は、車両に搭載される車載機器との間で第１の周波数帯を用いて無線通信を行う第１の通信部および第１の周波数帯より高域の周波数を含む第２の周波数帯を用いた超広帯域無線通信を行う第２の通信部と、所定の報知動作を行う報知部と、第１の通信部、第２の通信部および報知部を制御する第１の制御部とを備え、第１の制御部は、第１の通信部に、車載機器との認証のための無線通信を行わせ、第２の通信部に、車載機器までの距離を測定するための無線通信を行わせ、第１の通信部が、車載機器から、距離の測定に失敗したことを表す無線信号を受信すると、報知部に所定の報知動作を行わせる。【選択図】図１
