VEHICULAR COMMUNICATION SYSTEM, ON-VEHICLE DEVICE, AND COMPUTER PROGRAM
PROBLEM TO BE SOLVED: To provide a vehicular communication system, an on-vehicle device, and a computer program which can notify a user of detailed positional information about a portable machine.SOLUTION: A vehicular communication system includes: an on-vehicle device which includes a first on-vehicle transmission section which has an antenna for defining a first range including a part or all of a cabin as an output range and transmitting a first radio signal and a first on-vehicle reception section which receives a response signal corresponding to the first radio signal; and a portable machine which transmits the response signal when receiving the first radio signal. The on-vehicle device further includes: a second on-vehicle transmission section which defines a second range including a part of the first range but not including all as an output range and has an antenna for transmitting a second radio signal; a second on-vehicle reception section which receives a response signal corresponding to the second radio signal; a determination section which determines the range of the position of the portable machine on the basis of the combinations of the propriety of reception in the first on-vehicle reception section and the second on-vehicle reception section; and an output section which outputs the determined range.SELECTED DRAWING: Figure 1
【課題】携帯機の詳細な位置情報を使用者に通知することが可能な車輌用通信システム、車載装置及びコンピュータプログラムを提供する。【解決手段】車輌用通信システムは、車室内の一部又は全部を含む第１の範囲を出力範囲として第１の無線信号を送信するアンテナを有する第１車載送信部及び第１の無線信号に対応する応答信号を受信する第１車載受信部を備える車載装置と、第１の無線信号を受信した場合に応答信号を送信する携帯機とを含み、車載装置は、第１の範囲の一部を含むが全部を含まない第２の範囲を出力範囲とし、第２の無線信号を送信するアンテナを有する第２車載送信部、第２の無線信号に対応する応答信号を受信する第２車載受信部と、第１車載受信部及び第２車載受信部における受信の可否の組み合わせに基づいて前記携帯機の位置の範囲を判別する判別部、及び判別された範囲を出力する出力部を更に備える。【選択図】図１
