During the warning operation, operating power is supplied from the vehicle-mounted battery to the low-power communication circuit 33 and the microcomputer 34.

超音波マイク３１は、所定周波数の超音波の波動を高感度で捉える仕様のものであり、捉えた波動は電気信号に変換される。
マイクロコンピュータ３４は、その電気信号が、所定周波数の超音波によるものであるか否かを判別し、所定周波数の超音波によるものであると判別すると、サイレン３２に通電を行って警報音を発報させるとともに、操作リモコン１への異常発生の通報を小電力通信回路３３に指示する。 The ultrasonic microphone 31 has a specification for capturing an ultrasonic wave having a predetermined frequency with high sensitivity, and the detected wave is converted into an electric signal.
The microcomputer 34 determines whether or not the electrical signal is based on an ultrasonic wave having a predetermined frequency. If the microcomputer 34 determines that the electric signal is based on an ultrasonic wave having a predetermined frequency, the microcomputer 34 energizes the siren 32 to generate an alarm sound. And instructing the low-power communication circuit 33 to report an abnormality to the operation remote controller 1.

つぎに、車両用盗難防止システムＡの車両への組み付けおよび作動を説明する。
開閉部を開けると、スイッチ２２が閉成状態になって可聴周波を超える超音波２５が車室内へ発信される様に、超音波発信器２を、内蔵電池２１を接続して車両の開閉部（例えば、運転席側のドアの内側）の目立たない場所に取り付ける。なお、取り付けは、接着剤、両面テープ、ネジ等で行う。 Next, assembly and operation of the vehicle antitheft system A to a vehicle will be described.
When the opening / closing part is opened, the ultrasonic transmitter 2 is connected to the built-in battery 21 so that the ultrasonic wave 25 exceeding the audible frequency is transmitted to the vehicle interior when the switch 22 is closed. Install it in an inconspicuous place (for example, inside the door on the driver's seat side). Attachment is performed with an adhesive, double-sided tape, screws, and the like.

超音波マイク３１がセラミック振動子２４の方向を向く様に、車載器３を座席下やトランクルーム等に設置し、車載バッテリに電源コードを接続する。同時に、操作リモコン１のスイッチ１２で遠隔操作を行える様にするための配線も行う。
車両を駐車後、車両の所有者が操作リモコン１を携帯する。 The vehicle-mounted device 3 is installed under the seat or in the trunk room so that the ultrasonic microphone 31 faces the ceramic vibrator 24, and the power cord is connected to the vehicle-mounted battery. At the same time, wiring for enabling remote operation with the switch 12 of the operation remote controller 1 is also performed.
After parking the vehicle, the owner of the vehicle carries the operation remote controller 1.

通常、車両の所有者は、図１の（ａ）に示す様に、携帯した操作リモコン１のスイッチ１２を操作して小電力電波１４を送信し、エンジン始動やドアの施錠・開錠等の遠隔操作を行う。なお、スイッチ操作で操作が行われると小電力電波１３が送信され、アンサーバックによりＬＥＤ１１が点灯する。   Normally, as shown in FIG. 1A, the owner of the vehicle operates the switch 12 of the portable operation remote controller 1 to transmit a low-power radio wave 14 to start the engine or lock / unlock the door. Perform remote control. In addition, when operation is performed by switch operation, the low electric power radio wave 13 will be transmitted and LED11 will light by answerback.

所有者が車両から離れている隙に、超音波発信器２を取り付けた開閉部を不審者が開けると、スイッチ２２が閉成するのでセラミック振動子２４から超音波２５が発信される｛図１の（ｂ）参照｝。
超音波マイク３１が超音波２５を捉えて電気信号をマイクロコンピュータ３４へ出力し、超音波発信器２から発信された超音波２５であるとマイクロコンピュータ３４が判別する。 When the suspicious person opens the opening / closing part to which the ultrasonic transmitter 2 is attached while the owner is away from the vehicle, the switch 22 is closed, so that the ultrasonic wave 25 is transmitted from the ceramic vibrator 24 {FIG. (B)}.
The ultrasonic microphone 31 captures the ultrasonic wave 25 and outputs an electric signal to the microcomputer 34, and the microcomputer 34 determines that the ultrasonic wave 25 is transmitted from the ultrasonic transmitter 2.

マイクロコンピュータ３４がサイレン３２へ通電を行うとともに、操作リモコン１への異常発生の通報を小電力通信回路３３に指示し、小電力電波１３が送信される。これにより、サイレン３２が警報音を発報するとともに、車両の所有者が携帯する操作リモコン１のＬＥＤ１１が点灯し、ブザーが鳴動する｛図１の（ｂ）参照｝。   The microcomputer 34 energizes the siren 32 and instructs the low power communication circuit 33 to notify the operation remote controller 1 of the occurrence of abnormality, and the low power radio wave 13 is transmitted. As a result, the siren 32 issues a warning sound, the LED 11 of the operation remote controller 1 carried by the owner of the vehicle lights up, and the buzzer sounds {see (b) of FIG. 1}.

本実施例の車両用盗難防止システムＡは、以下の利点を有する。
〔あ〕超音波発信器２は、内蔵電池２１を有し、不審者の不法行為を超音波２５で車載器３へ伝えているので、超音波発信器２側の電源コードや、超音波発信器２と車載器３とを接続するための接続コードが不要である。
このため、超音波発信器２を車両の開閉部へ、容易に、且つ目立たない様に取り付けることができる。 The vehicle antitheft system A of the present embodiment has the following advantages.
[Ah] The ultrasonic transmitter 2 has a built-in battery 21 and transmits the illegal action of the suspicious person to the vehicle-mounted device 3 using the ultrasonic wave 25. Therefore, the power cord on the ultrasonic transmitter 2 side and the ultrasonic transmission A connection cord for connecting the device 2 and the vehicle-mounted device 3 is not necessary.
For this reason, the ultrasonic transmitter 2 can be easily and inconspicuously attached to the opening / closing part of the vehicle.

また、超音波発信器２を取り付ける開閉部を増やしても、車載器３側の設定を変更する必要がなく、接続コードも不要である。この場合、超音波発信器２を増設する車両の開閉部は、超音波２５が届く所であれば、他の車両ドアの内側、ドアの窓、トランクカバー裏面、ボンネット裏面等が考えられる。   Moreover, even if the number of open / close parts to which the ultrasonic transmitter 2 is attached is increased, it is not necessary to change the setting on the vehicle-mounted device 3 side, and a connection cord is also unnecessary. In this case, the opening / closing part of the vehicle to which the ultrasonic transmitter 2 is added may be the inside of another vehicle door, the door window, the trunk cover back surface, the bonnet back surface, etc., as long as the ultrasonic wave 25 reaches.

〔い〕不審者が車両の開閉部を開けた場合（不法行為発生時）に超音波発信器２から発信される超音波２５は、所定周波数の超音波であるので、他の超音波を超音波マイク３１が捉えても、マイクロコンピュータ３４が誤判別しない。
このため、他の超音波を超音波マイク３１が捉えた場合に、サイレン３２が警報音を発報したり、操作リモコン１のＬＥＤ１１が点灯したり、ブザーが鳴動したりしない。 [Yes] When the suspicious person opens the opening / closing part of the vehicle (when an illegal act occurs), the ultrasonic wave 25 transmitted from the ultrasonic transmitter 2 is an ultrasonic wave having a predetermined frequency, and thus other ultrasonic waves are Even if the sound wave microphone 31 catches, the microcomputer 34 does not make a mistake.
For this reason, when the ultrasonic microphone 31 captures other ultrasonic waves, the siren 32 does not issue an alarm sound, the LED 11 of the operation remote controller 1 does not light, and the buzzer does not sound.

つぎに、本発明の実施例２に係る車両用盗難防止装置Ｂ（請求項１、２、３に対応）を、図２に基づいて説明する。本実施例の車両用盗難防止装置Ｂは、下記に示す点が車両用盗難防止システムＡと異なる。

When the suspicious person opens the opening / closing part to which the ultrasonic transmitter 2 is attached while the owner is away from the vehicle, the switch 22 is closed, so that the ultrasonic wave 25 is transmitted from the ceramic vibrator 24 {FIG. (B)}.
The ultrasonic microphone 31 captures the ultrasonic wave 25 and outputs an electric signal to the microcomputer 34, and the microcomputer 34 determines that the ultrasonic wave 25 is transmitted from the ultrasonic transmitter 2.
The microcomputer 34 energizes the siren 32. As a result, the siren 32 issues an alarm sound {see FIG. 2 (b)}.

このため、超音波発信器２を車両の開閉部へ、容易に、且つ目立たない様に取り付けることができる。 The vehicle antitheft device B of the present embodiment has the following advantages.
[U] The ultrasonic transmitter 2 has the built-in battery 21 and transmits the suspicious person's illegal action to the vehicle-mounted device 3 using the ultrasonic wave 25. Therefore, the power cord on the ultrasonic transmitter 2 side or ultrasonic transmission A connection cord for connecting the device 2 and the vehicle-mounted device 3 is not necessary.
For this reason, the ultrasonic transmitter 2 can be easily and inconspicuously attached to the opening / closing part of the vehicle.

また、超音波発信器２を取り付ける開閉部を増やしても、車載器３側の設定を変更する必要がなく、接続コードも不要である。この場合、超音波発信器２を増設する車両の開閉部は、超音波２５が届く所であれば、他の車両ドアの内側、ドアの窓、トランクカバー裏面、ボンネット裏面等が考えられる。   Moreover, even if the number of open / close parts to which the ultrasonic transmitter 2 is attached is increased, it is not necessary to change the setting on the vehicle-mounted device 3 side, and a connection cord is also unnecessary. In this case, the opening / closing part of the vehicle to which the ultrasonic transmitter 2 is added may be the inside of another vehicle door, the door window, the trunk cover back surface, the bonnet back surface, etc., as long as the ultrasonic wave 25 reaches.

〔え〕不審者が車両の開閉部を開けた場合（不法行為発生時）に超音波発信器２から発信される超音波２５は、所定周波数の超音波であるので、他の超音波を超音波マイク３１が捉えても、マイクロコンピュータ３４が誤判別しない。
このため、他の超音波を超音波マイク３１が捉えた場合に、サイレン３２が警報音を発報しない。 [Eh] When the suspicious person opens the opening / closing part of the vehicle (when illegal activity occurs), the ultrasonic wave 25 transmitted from the ultrasonic transmitter 2 is an ultrasonic wave having a predetermined frequency, and therefore other ultrasonic waves are Even if the sound wave microphone 31 catches, the microcomputer 34 does not make a mistake.
