ANTI-THEFT SECURITY DEVICE FOR VEHICLE
PROBLEM TO BE SOLVED: To provide an anti-theft security device for a vehicle that less sends an alarm for failure in authentication code matching or an alarm for mobile phone non-detection by mistake when mounted on a small-sized two-wheel vehicle.SOLUTION: The anti-theft security device comprises: an on-vehicle machine having a transmission circuit, a reception circuit, and a first storage circuit stored with a first authentication code; and a portable machine having a transmission circuit, a reception circuit, and a second storage circuit stored with a second authentication code. The on-vehicle machine transmits an authentication code request signal by radio by using a long-wave range frequency, and the portable machine transmits the second authentication code stored in the second storage circuit in response by using a frequency higher than the long-wave range. After confirming that the second authentication code that the on-vehicle machine receives matches the first authentication code stored in the first storage circuit, the portable machine continuously transmits the second authentication code by radio at predetermined time intervals.SELECTED DRAWING: Figure 1
【課題】車両用盗難防止装置を小型二輪車に搭載する場合、誤って認証コード照合失敗の警告または携帯機未検出の警報を出すことが少ない車両用盗難防止装置を得る。【解決手段】送信回路、受信回路及び第１認証コードが記憶された第１記憶回路を有する車載機と、送信回路、受信回路及び第２認証コードが記憶された第２記憶回路を有する携帯機とを備え、車載機が認証コード要求信号を長波帯の周波数を用いて無線送信し、これに応答して携帯機が第２記憶回路に記憶された第２認証コードを長波帯よりも高い周波数を用いて無線送信し、前記車載機が受信した第２認証コードが車載機の第１記憶回路に記憶されていた第１認証コードと一致したと確認した後、前記携帯機は第２認証コードを所定の時間間隔で継続して無線送信する。【選択図】図１
