WIRELESS COMMUNICATION APPARATUS, VEHICLE EQUIPPED WITH THE SAME, AND WIRELESS COMMUNICATION SYSTEM
To reduce dark current in a wireless communication apparatus equipped with a communicator that performs wireless communication with a portable device.SOLUTION: A vehicle 10 includes an NFC communicator 12 that uses a communication system that complies with NFC standards, a BLE communicator 14 that uses a communication system that complies with BLE communication standards, and a wireless controller 16 that controls the NFC communicator 12 and the BLE communicator 14. Each of the NFC communicator 12 and the BLE communicator 14 is configured to perform polling for detecting a portable device 50 and authentication of the portable device 50 detected by the polling. When the authentication is completed in one of the NFC communicator 12 and the BLE communicator 14, the wireless controller 16 stops the polling by the other communicator.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、ＮＦＣ通信機１２及びＢＬＥ通信機１４を制御する無線コントローラ１６とを備える。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と、ポーリングにより検知された携帯機器５０の認証とを行なうように構成される。無線コントローラ１６は、ＮＦＣ通信機１２及びＢＬＥ通信機１４の一方において認証が完了した場合に、他方の通信機によるポーリングを停止する。【選択図】図１
