RADIO COMMUNICATION SYSTEM
PROBLEM TO BE SOLVED: To provide a radio communication system capable of reducing power consumption.SOLUTION: A radio communication system includes an on-vehicle machine mounted on a vehicle, and a portable machine which can be carried by a user. The on-vehicle machine includes a first transmission section for wirelessly transmitting an identification code of the vehicle or the on-vehicle machine intermittently toward the outside of the vehicle, and a detection section for detecting the existence of the portable machine by receiving a response signal wirelessly transmitted from the portable machine. The portable machine includes: a receiving antenna for receiving the identification code; a first collation section for collating the identification code received by the receiving antenna with a code registered in the portable machine; and a transmission control section wirelessly transmitting the response signal when collation by the first collation section is established, and not transmitting the response signal when the collation by the first collation section is not established.SELECTED DRAWING: Figure 1
【課題】消費電力を削減できる、無線通信システムの提供。【解決手段】車両に搭載された車載機と、ユーザが携帯可能な携帯機とを備え、前記車載機は、前記車両又は前記車載機の識別コードを前記車両の外部に向けて間欠的に無線送信する第１の送信部と、前記携帯機から無線送信された応答信号を受信することにより、前記携帯機の存在を検知する検知部とを有し、前記携帯機は、前記識別コードを受信する受信アンテナと、前記受信アンテナが受信した前記識別コードを前記携帯機に登録されたコードと照合する第１の照合部と、前記第１の照合部による照合が成立した場合、前記応答信号を無線送信し、前記第１の照合部による照合が成立しない場合、前記応答信号を送信しない、送信制御部とを有する、無線通信システム。【選択図】図１
