RADIO COMMUNICATION DEVICE, VEHICLE HAVING THE SAME, AND RADIO COMMUNICATION SYSTEM
To reduce a dark current in a radio communication device having a communication apparatus which radio communicates with a mobile apparatus.SOLUTION: A vehicle 10 includes: an NFC communication apparatus 12 which uses a communication method conforming to an NFC standard; a BLE communication apparatus 14 which uses a communication method conforming to a BLE communication standard; and a radio controller 16. The communication range of the BLE communication apparatus 14 is longer than the communication range of the NFC communication apparatus 12. Each of the NFC communication apparatus 12 and the BLE communication apparatus 14 is configured to perform polling in order to detect a mobile apparatus 50. A radio controller 16 starts polling by the NFC communication apparatus 12 on completion of connection between the BLE communication apparatus 14 and the mobile apparatus 50 by radio.SELECTED DRAWING: Figure 1
【課題】携帯機器と無線通信を行なう通信機を備える無線通信装置において、暗電流を低減する。【解決手段】車両１０は、ＮＦＣ規格に従う通信方式を用いるＮＦＣ通信機１２と、ＢＬＥ通信規格に従う通信方式を用いるＢＬＥ通信機１４と、無線コントローラ１６とを備える。ＢＬＥ通信機１４の通信可能距離は、ＮＦＣ通信機１２の通信可能距離よりも長い。ＮＦＣ通信機１２及びＢＬＥ通信機１４の各々は、携帯機器５０を検知するためのポーリングを行なうように構成される。無線コントローラ１６は、ＢＬＥ通信機１４と携帯機器５０との無線による接続が完了した場合に、ＮＦＣ通信機１２によるポーリングを開始する。【選択図】図１
