VEHICULAR AUTHENTICATION SYSTEM AND PORTABLE MACHINE
PROBLEM TO BE SOLVED: To enable a user to recognize that unauthorized authentication utilizing radio communication is performed for a driver's own vehicle without reference to a distance between a portable machine and the vehicle.SOLUTION: A collation ECU comprises a sound output processing unit that makes even electronic sound in an audible zone output from a loudspeaker when a request signal is transmitted from a transmission processing unit. A portable machine 2 comprises a microphone 24 for collecting sound, and a sound collation unit 214 for collating the sound, which is collected by the microphone 24, with normal electronic sound. A UHF transmission unit 23 of the portable machine does not transmit a request response signal including a portable machine identification code, when collation is not established in the sound collation unit 214, even in the case where the request signal is received.SELECTED DRAWING: Figure 5
【課題】帯機と車両との距離に関わらず、無線通信を利用した不正な認証が自車に対して行われたことをユーザが認知できるようにする。【解決手段】照合ＥＣＵは、送信処理部で要求信号を送信させる場合にスピーカから可聴域の電子音も出力させる音出力処理部を備え、携帯機は、音を集音するマイク２４と、マイク２４で集音した音を、正規の電子音と照合する音照合部２１４とを備え、携帯機２のＵＨＦ送信部２３は、要求信号を受信した場合であっても、音照合部２１４で照合が成立しなかった場合には、携帯機識別コードを含む要求応答信号を送信しない。【選択図】図５
