MOBILE DEVICE AND AUTHENTICATION SYSTEM
To enable the power saving of a mobile device through the use of an acceleration sensor, and to enable the prevention of the useless continuation of operation for power saving in the event of a failure in the acceleration sensor.SOLUTION: A mobile device comprises: an acceleration sensor unit 34; an LF reception section 32 for performing short-range wireless communication with an antenna for vehicle-cabin-outside collation and an antenna for vehicle-cabin-inside collation which are provided in an authentication object; a reception stop section 355 for stopping the reception operation of the LF reception section 32 on the basis of the detection result of the acceleration sensor unit 34; a failure detection section 356 for detecting a failure in the acceleration sensor unit 34; and an operation switching section 357 which, when a failure in an acceleration detection section is detected by the failure detection section 356, prevents the reception stop section 355 from stopping the reception operation of the LF reception section 32.SELECTED DRAWING: Figure 7
【課題】携帯機の省電力化を、加速度センサを用いることで可能にしつつ、この加速度センサが故障した場合に、省電力化を行わせるための動作を無駄に継続させないようにすることを可能にする。【解決手段】加速度センサユニット３４と、認証対象に備えられる車室外照合用のアンテナ，車室内照合用のアンテナの間で近距離無線通信を行うＬＦ受信部３２と、加速度センサユニット３４での検出結果をもとにＬＦ受信部３２の受信動作を停止させる受信停止部３５５と、加速度センサユニット３４の故障を検知する故障検知部３５６と、故障検知部３５６で加速度検出部の故障を検知した場合には、受信停止部３５５でのＬＦ受信部３２の受信動作の停止を行わせないようにする動作切替部３５７とを備える。【選択図】図７
