To provide an on-vehicle radio communication device, a communication system, a portable communication device, a communication program, and a communication method with which it can be expected that notification to a user is carried out properly.SOLUTION: An on-vehicle radio communication device (BCM) 2 includes: a transmission part for transmitting a radio signal from a surface wave antenna 5 loaded on a vehicle: a reception part for receiving a radio signal via the surface wave antenna; a determination part for determining whether a portable communication device exists either inside or outside of the vehicle on the basis of a received response signal, when a response signal with respect to a radio signal transmitted by the transmission part is received by the reception part from a portable communication device (a smartphone) 7; and a notification part for performing notification according to a result of the determination part. The portable communication device includes: a reception part for receiving a radio signal transmitted by the on-vehicle radio communication device; a detector for detecting signal intensity of the radio signal received by the reception part; a generation part for generating a response signal containing information related to the signal intensity detected by the detector; and a transmission part for transmitting the response signal generated by the generation part, as a radio signal.SELECTED DRAWING: Figure 1

    【課題】ユーザへの通知を適切に行うことが期待できる車載無線通信装置、通信システム、可搬型通信装置、通信プログラム及び通信方法を提供する。【解決手段】車載無線通信装置(BCM)2は、車両に搭載された表面波アンテナ5から無線信号を送信する送信部と、表面波アンテナにて無線信号を受信する受信部と、送信部が送信した無線信号に対する可搬型通信装置(スマートフォン)7からの応答信号を受信部にて受信した場合に、受信した応答信号に基づいて可搬型通信装置が車両の内外のいずれに存在するかを判定する判定部と、判定部の結果に基づく通知を行う通知部とを備える。可搬型通信装置は、車載無線通信装置が送信した無線信号を受信する受信部と、受信部にて受信した無線信号の信号強度を検出する検出部と、検出部が検出した信号強度に係る情報を含む応答信号を生成する生成部と、生成部が生成した応答信号を無線信号として送信する送信部とを備える。【選択図】図1
