JP 11-321564 A

  However, since a controller is connected to the limit switch 230 by a cord, when considering the mounting of the above-described device on a vehicle, a design in consideration of the handling of the cord is necessary, which is a factor that hinders the freedom of mounting. It was. In addition, it is required to be resistant to invalidation as an automobile crime prevention device.

  The present invention has been made under such a background, and an object of the present invention is to provide an automobile crime prevention device that can improve the degree of freedom of mounting and is resistant to invalidation.

  In the invention described in claim 1, a fraud detector that is attached to a detection target part of a fraud in a vehicle and is provided in the fraud detector to detect the fraud to the vehicle, the fraud A speaker that is activated when the detection tool detects fraudulent acts on the vehicle and outputs a warning sound by adding a fraud detection identification sound, and a microphone that is mounted on the vehicle and collects sound emitted by the speakers And an identification sound extraction means for extracting the fraud detection identification sound from the sound collected by the microphone and detecting the fraud to the vehicle.

  According to the first aspect of the present invention, the cheating detector is attached to the detection target part of cheating in the vehicle, and cheating on the vehicle is detected. When the cheating detector detects a cheating action on the vehicle, a speaker provided in the cheating detector is activated to output the alarm sound with a cheating detection identification sound. The sound emitted from the speaker is collected by a microphone mounted on the vehicle. The identification sound extraction means extracts the fraud detection identification sound from the collected sound and detects the fraud to the vehicle. As a result, it is possible to make contact outside the vehicle and make it impossible to start the engine.

  Therefore, since the detection tool is equipped with a speaker, wiring is not necessary, and since it is a method of communicating with sound, it is necessary to prepare a disturbing sound to invalidate the function, and it is easy to prevent invalidation by unauthorized persons .

  According to a second aspect of the present invention, in the automobile crime prevention device according to the first aspect, the cheating detector is attached to a window glass of a vehicle and is elastic at a position shifted in the plane of the window glass. And pulverizing in a partial area of the window glass due to breakage of the window glass to detect breakage of the window glass, and the speaker detects that the cheating detector is a partial area of the window glass. The gist is to start by performing crushing and to add a window glass breakage detection identification sound to the alarm sound and output it.

  According to the second aspect of the present invention, when the window glass is broken, the strength of the window glass is lowered, so that the detection tool crushes a partial area of the window glass by the biasing force, thereby detecting the breakage of the window glass. Is done. In addition, since it is biased by its own elasticity at a position shifted in the plane of the window glass, the window glass is surely crushed by breaking the window glass (with a decrease in the strength of the window glass). Glass breakage can be reliably detected. Therefore, it is possible to reliably detect the breakage of the window glass even when the window glass remains without being completely pulverized with the breakage of the window glass using the detection tool.

  The vehicle crime prevention device according to claim 1 or 2, wherein the fraud detection detection sound output from the speaker has a frequency different from that of the alarm sound, as described in claim 3. As described in claim 5, even if the fraud detection identification sound is added to the warning sound by AM modulation, the fraud detection identification sound is added to the warning sound by FM modulation. However, as described in claim 6, the fraud detection identifying sound may be an ultrasonic wave.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to improve the freedom degree of mounting, the crime prevention apparatus for motor vehicles strong against an invalidation act can be provided.

  The guide piece 19 of the lift arm 12 and the guide piece 20 of the equalizer arm 18 are movably fitted to the window glass bracket 22, and the guide piece 21 of the equalizer arm 18 is located on the outside of the modular panel 6 in FIG. It is movably guided to an equalizer arm bracket (posture maintenance rail) 23 fixed to the surface.

  On the other hand, a window glass holder 24 is fixed to the lower edge of the window glass 5 at the front and rear thereof. The window glass holder 24 is fixed to the lower edge of the window glass 5 in advance, and the window glass 5 having the window glass holder 24 is inserted from the gap between the outer panel 2 and the inner panel 3, and the window glass bracket 22 is tightened by bolts 25. It is fixed to.

  As shown in FIG. 4, a pair of front and rear glass runs 26 are erected. The glass run 26 is made of a rubber material. The window glass 5 is movably supported by a pair of front and rear glass runs 26 as rail members. That is, the front and rear end portions of the window glass 5 are guided by the glass run 26 and can move up and down.

  When the pinion 16 is driven forward and backward via the electric drive unit 14 of FIG. 3, the lift arm 12 swings about the shaft 13 via the sector gear 15, and as a result, the window glass bracket 22 (window glass 5) is moved. The equalizer arm 18, the guide pieces 19, 20, 21 and the equalizer arm bracket 23 are moved up and down while being held in a substantially horizontal state. Thus, the window glass 5 is raised and lowered, and the opening 4 of the vehicle can be freely opened and closed by the window glass 5.

FIG. 5 shows a longitudinal section taken along line AA in FIG. In FIG. 5, the clip 40 and the buzzer module 50 of the automobile crime prevention device 30 are arranged inside the vehicle door 1.
In FIG. 8, the perspective view of the clip 40 and the buzzer module 50 is shown. 9A and 9B show the clip 40 and the buzzer module 50, where FIG. 9A is a front view and FIG. 9B is a cross-sectional view taken along line AA of FIG.

  In FIG. 5, the window glass 5 is disposed between the outer panel 2 and the inner panel 3 in a state of being sealed by a weather strip 7. A door trim 8 is disposed inside the inner panel 3. The clip 40 is disposed at the lower end of the window glass 5 and sandwiches the window glass 5.

  As shown in FIGS. 8 and 9, the clip 40 is configured by bending a single plate spring steel plate. The clip 40 includes first and second members 41 and 42 and a bent portion (connecting portion) 43 that face each other. The first member 41 on the back side has a rectangular shape, and the second member 42 on the front side has a square shape that is narrower than the first member 41. The window glass 5 is disposed between the first member 41 on the back side and the second member 42 on the front side, and the first member 41 and the second member 42 are urged toward the window glass 5 toward each other. .

  The bent portion 43 connects the first member 41 and the second member 42. The bent portion 43 is bent in two steps, and the width of the second-stage bent portion 43b is narrower than the thickness of the window glass 5, and the end surface of the window glass 5 is in contact with the bent portion 43a of the first step. That is, a stepped portion is formed in the bent portion 43 of the clip 40, the end surface of the window glass 5 is in contact with the stepped portion, and the lower end of the window glass 5 is not fitted (in the vicinity of the lower side portion). The window glass 5 is not sandwiched).

  A rectangular through hole 44 is formed at the center of the first member 41. The second member 42 is located at a position corresponding to the through hole 44. Projections 45 projecting to the front side are formed at the left and right upper corners of the first member 41, and are in contact with one surface (back surface 5b) of the window glass 5 at the tip of the projection 45 as shown in FIG. The second member 42 in FIGS. 8 and 9 is in contact with the other surface (surface 5 a) of the window glass 5 at a location corresponding to the inside of the through hole 44 of the first member 41. Therefore, the contact part with the window glass 5 in the 1st member 41 is provided so that it may be spaced apart in two places in the surface of the window glass 5, and the contact part with the window glass 5 in the 2nd member 42 may be pinched | interposed. Both contact portions of the first member 41 with the window glass 5 are connected around the contact portion of the second member 42 with the window glass 5. That is, the part facing the window glass 5 in the first member 41 has a reverse concave shape, and thus the window glass 5 is broken. The second member 42 is bonded to the window glass 5.

  Thus, in a state where the first member 41 and the second member 42 are in contact with each other at a position shifted in the plane of the window glass 5 between the first member 41 and the second member 42 where the window glass 5 is disposed. It is urged in the direction of approaching each other by its own elasticity. That is, force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5. Further, the clip 40 clamps (holds) the lower end portion of the window glass 5 with a predetermined force or more.

  A buzzer module 50 is attached to the first member 41 of the clip 40. The case 51 of the buzzer module 50 has a box shape having a predetermined thickness as an overall shape, and one surface of the case 51 is bonded to the first member 41 of the clip 40. A recess 51 a is formed on one surface (bonding surface) of the case 51. A protrusion-type push button switch 52 is provided on the bottom surface of the recess 51a so as to appear and retract. The push button switch 52 always protrudes, and this state is an off state. On the other hand, when the push button switch 52 is pressed, the switch is turned on.

  As shown in FIG. 2, the internal configuration of the buzzer module 50 includes a push button switch 52, oscillators 53 and 54, a buzzer sound signal generator 55, an identification sound signal generator 56, a power amplifier 57, and a speaker (buzzer) 58. I have. Oscillators 53 and 54 are connected to the push button switch 52. A buzzer sound signal generator 55 is connected to the oscillator 53. An identification sound signal generator 56 is connected to the oscillator 54. The output of the buzzer sound signal generator 55 and the output of the identification sound signal generator 56 are collected and connected to the speaker 58 via the power amplifier 57. Further, the buzzer module 50 is provided with a battery (power source) (not shown).

  As shown in FIG. 2, the glass breakage determination circuit 60 includes a microphone 61, bandpass filters 62 and 63, a buzzer sound determination circuit 64, an identification sound determination circuit 65, and an AND gate 66. The microphone 61 collects sound emitted from the speaker 58 of the buzzer module 50. A bandpass filter 62 and a bandpass filter 63 are connected to the microphone 61. A buzzer sound determination circuit 64 is connected to the band pass filter 62. An identification sound determination circuit 65 is connected to the band pass filter 63. An AND gate 66 is connected to the buzzer sound determination circuit 64 and the identification sound determination circuit 65. The AND gate 66 of the determination circuit 60 is connected to the security ECU 70 via an in-vehicle cable.

Next, an operation of the automobile crime prevention device 30 configured as described above, that is, an operation when the window glass 5 is broken (broken) will be described.
In normal times, when the occupant leaves the vehicle, the window glass 5 is fully closed or slightly opened by a few centimeters. Further, the clip 40 disposed at the end of the window glass 5 sandwiches the end of the window glass 5. Specifically, the window glass 5 is sandwiched between the first member 41 and the second member 42 by the elastic force of the clip 40 itself. Further, the push button switch 52 of the buzzer module 50 is not pressed and is in an off state.

  If the window glass 5 is broken from this state, the strength thereof is lowered. That is, when a part of the window glass 5 made of tempered glass is broken, as shown in FIG. 10, the window glass 5 is cracked and the strength is significantly reduced (the glass strength is reduced when the glass is broken).

  As the strength decreases, the clip 40 crushes the end portion (lower end portion) of the window glass 5 by its clamping force as shown in FIG. That is, the window glass 5 made of tempered glass is partially and completely pulverized (pulverized) by its own spring force.

  Specifically, as shown in FIG. 10, the window glass 5 is pushed by the urging force of the second member 42 and comes into contact with the first member 41 of the clip 40. In this state, the window glass 5 is pressed by the second member 42 in a state where the periphery of the through hole 44 is supported, and the window glass 5 in the through hole 44 is shattered as shown in FIG. 5 is broken into an inverted U shape).

  Then, the window glass breakage detection clip 40 pulverizes in a partial region of the window glass 5 to detect breakage of the window glass 5. In this way, if the tempered glass is partially broken, it can be cracked and the strength is remarkably reduced, so that undetected and erroneous detection can be minimized.

  Further, as shown in FIG. 4, it is possible to detect breakage of the window glass 5 even when the window glass 5 is not in the fully closed position. Specifically, in the prior art (Patent Document 1), since the movement of the window glass when the window glass was fully closed was detected, it was not possible to detect breakage of the window glass when the window glass was not in the fully closed position. In this embodiment, it is possible to detect breakage of the window glass even when the window glass is slightly opened for ventilation or the like and the window glass is not in the fully closed position.

  Moreover, the clip 40 of FIG. 9 has the 1st member 41 and the 2nd member 42 which bent and opposed the steel plate for leaf | plate springs, and between the 1st member 41 and the 2nd member 42 in which the window glass 5 is arrange | positioned. In a state where the first member 41 and the second member 42 are in contact with each other at a position shifted in the plane of the window glass 5, they are biased in opposite directions to the glass surface by their own elasticity (in directions approaching each other) Energized). As a result, a force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5, so that the window glass is accompanied by breakage of the window glass 5 (with a decrease in the strength of the window glass 5). It is possible to reliably detect the breakage of the window glass 5 by reliably crushing the end portion of the window 5.

  Further, the contact portion of the first member 41 of the clip 40 of FIG. 9 with the window glass 5 is separated from the contact portion of the second member 42 with the window glass 5 in the plane of the window glass 5 and the first member. Both contact portions with the window glass 5 in 41 are connected around the contact portion with the window glass 5 in the second member 42. Therefore, as shown in FIG. 10, the window glass 5 is pressed in a state where the window glass 5 is in contact with the first member 41 around the contact portion of the second member 42 with the window glass 5. That is, in the first member 41, the window glass 5 is pressed inside the inner periphery of the through hole 44 in a state where the window glass 5 is supported around the through hole 44. Thereby, as shown in FIG. 11, the edge part of the window glass 5 can be grind | pulverized easily.

  On the other hand, as described above, when the clip 40 pulverizes in a partial region of the window glass 5, the second member 42 returns to the original state by the elastic force of the clip 40 as shown in FIG. At this time, the second member 42 presses the push button switch 52 of the buzzer module 50. As a result, the push button switch 52 is turned on.

When the push button switch 52 of the buzzer module 50 is turned on, the buzzer module 50 of FIG. 2 operates as follows.
When the push button switch 52 in FIG. 2 is turned on, a signal is sent from the oscillator 53 to the buzzer sound signal generator 55 to generate an alarm sound signal (buzzer sound signal). When the push button switch 52 is turned on, a signal is sent from the oscillator 54 to the identification sound signal generator 56 to generate an identification sound signal. Then, the identification sound signal by the identification sound signal generator 56 is added (added) to the alarm sound signal (buzzer sound signal) of the buzzer sound signal generator 55, amplified by the power amplifier 57, and output as a sound from the speaker 58. Is done. That is, the window glass breakage detection identification sound is added to the alarm sound and output from the speaker 58. At this time, a sound of 100 dB or more is emitted from the speaker 58 to the surroundings. As a result, the person who broke the window glass is directly intimidated and informed to the surroundings.

  FIG. 7A shows an alarm sound signal (buzzer sound signal), and FIG. 7B shows an identification sound signal. In comparison between the waveform of the alarm sound signal (buzzer sound signal) and the waveform of the identification sound signal, the identification sound signal has a longer period than the alarm sound signal (buzzer sound signal). For example, the frequency of the identification sound signal is about 1000 Hz. FIG. 7C shows a signal after the alarm sound signal (buzzer sound signal) and the identification sound signal are added. As shown in FIG. 7C, an identification sound signal is added (superimposed) to the alarm sound signal (buzzer sound signal). That is, it is modulated and output from the speaker 58.

The sound emitted from the speaker 58 of the buzzer module 50 is taken into the microphone 61 of the determination circuit 60 in FIG. 2, and the determination circuit 60 operates as follows.
The sound emitted from the speaker 58 of the buzzer module 50 is converted into an electric signal by the microphone 61 (see FIG. 7C). The frequency component of the alarm sound signal (buzzer sound signal) in the electric signal from the microphone 61 is extracted by the band pass filter 62. That is, the component of FIG. 7A is demodulated with respect to FIG. Further, the frequency component of the identification sound signal in the electric signal from the microphone 61 is extracted by the band pass filter 63. That is, the component of FIG. 7B is demodulated with respect to FIG.

  The buzzer sound determination circuit 64 determines the presence or absence of an alarm sound (buzzer sound) from the period and intensity of the signal from the bandpass filter 62. In addition, the identification sound determination circuit 65 determines the presence or absence of the identification sound from the period and intensity of the signal from the band pass filter 63. That is, the window glass breakage detection identification sound is extracted from the sound collected by the microphone 61, and thereby the breakage of the window glass can be detected. The determination result by the buzzer sound determination circuit 64 and the determination result by the identification sound determination circuit 65 are sent to the AND gate 66. In the AND gate 66, when an alarm sound (buzzer sound) is detected by the buzzer sound determination circuit 64 and an identification sound is detected by the identification sound determination circuit 65, it is determined that the window glass is broken, and this is indicated. It is sent from the gate 66 to the security ECU 70 via the in-vehicle cable. The security ECU 70 notifies the management station outside the vehicle or the like to the owner of the vehicle by wireless communication or the like.

  In this manner, the push button switch 52 of the buzzer module 50 is turned on in conjunction with the crushing operation in the partial region of the window glass by the clip 40 accompanying the breakage of the window glass 5, and the breakage of the window glass is detected using the sound. To the determination circuit 60. That is, the buzzer module 50 modulates an alarm sound and an audible sound identification sound that becomes a window glass breakage detection signal and outputs the modulated sound from the speaker 58, and the determination circuit 60 demodulates the sound received by the microphone 61 to display the window. Extract glass breakage detection signal. Therefore, since the communication uses a large volume, it is difficult to be disturbed. In addition, in order to disturb the system, a loud sound is required, so that the person who broke the window glass cannot make the sound unless he / she makes a sound himself (disturbing work is difficult).

  Furthermore, since the identification sound is added to the alarm sound emitted from the buzzer module 50, it is preferable as a countermeasure against false alarms and mischief such as an alarm. Further, since the buzzer module 50 is mounted on the clip 40, wiring is not necessary.

According to the above embodiment, the following effects can be obtained.
(1) The automobile crime prevention device 30 includes a clip 40 as a cheating detector, a buzzer module 50, and a determination circuit 60. The clip 40 is attached to the window glass 5 as a part to be detected for illegal activities in the vehicle, and detects breakage of the window glass 5 as illegal activities on the vehicle. The speaker 58 of the buzzer module 50 is provided on the clip 40 and is activated when the clip 40 detects breakage of the window glass 5 to output an alarm sound with an unauthorized action detection identification sound. The microphone 61 of the determination circuit 60 is mounted on the vehicle and collects sound emitted from the speaker 58 of the buzzer module 50. The bandpass filter 63 and the identification sound determination circuit 65 of the determination circuit 60 serving as the identification sound extraction means are mounted on the vehicle, extract the fraud detection identification sound from the sound collected by the microphone 61, and the window glass 5. Detect damage. Based on this, it is possible to make contact outside the vehicle or make it impossible to start the engine. Therefore, since the clip 40 is equipped with a speaker, wiring is not necessary (harness handling can be reduced), and since it is a method of communication by sound, it is necessary to prepare an interfering sound in order to invalidate the function. It is easy to prevent an act of invalidation by an actor (a false alarm can be prevented without detecting even if a security buzzer sounds around). As a result, it is possible to provide a vehicle security device that can improve the degree of freedom of mounting and is resistant to invalidation.

  (2) The clip 40 as a fraud detection tool is attached to the window glass 5 of the vehicle, and is urged by its own elasticity at a position shifted in the plane of the window glass 5, resulting in breakage of the window glass 5. The window glass 5 is crushed in a partial area to detect breakage of the window glass 5. The speaker 58 of the buzzer module 50 is activated when the clip 40 crushes in a partial region of the window glass 5 and outputs a window glass breakage detection identification sound to the alarm sound. Therefore, even when the window glass 5 remains without being completely pulverized as the window glass 5 is broken by using the window glass breakage detection clip 40, the breakage of the window glass 5 can be reliably detected. Further, the buzzer module 50 is provided in the clip 40, and the buzzer module 50 is activated when the clip 40 crushes in a partial region of the window glass 5, and outputs an alarm sound. Therefore, a configuration for separately starting an alarm device such as a buzzer is not required, and an alarm can be performed with a simple configuration. Further, a member for detecting a displacement or the like associated with the crushing of a partial region of the window glass 5 in the clip 40 can be eliminated.

(3) The fraud detection identification sound output from the speaker 58 of the buzzer module 50 is different in frequency from the alarm sound. Therefore, the identification sound can be easily added to the alarm sound.
(Second Embodiment)
Next, the second embodiment will be described focusing on the differences from the first embodiment.

The base plate 110 has a square plate-like portion 111, and the square plate-like portion 111 has a long rectangular shape on the left and right. One surface of the square plate portion 111 is bonded to the window glass 5. A fitting protrusion 112 is formed on the right side of the other surface of the square plate-like portion 111. In addition, a through hole 113 extending in the left-right direction is formed in the upper and lower central part of the square plate-like part 111. The base plate 110 is formed thin and can be warped as shown in FIGS.

  In the urging steel plate 120, a fitting concave portion 122 is bent and formed on the right side of the main body 121, and the fitting concave portion 122 is fitted to the fitting protrusion 112 of the base plate 110. In the main body 121 of the urging steel plate 120, a first strip plate portion 123 and a second strip plate portion 124 are formed vertically on the right side of the fitting recess 122, and the first strip plate portion 123 and the second strip plate portion 124. Is extended to the left. Further, in the main body portion 121 of the urging steel plate 120, a third strip plate portion 125 is formed between the first strip plate portion 123 and the second strip plate portion 124 on the right side of the concave portion 122 for fitting. The strip plate portion 125 extends toward the left side. Here, as shown in FIG. 14, the left end of the third band plate portion 125 extends linearly with respect to the right base end, but the first band plate portion 123 and the second band plate portion 124 are on the right side. The left end extends with respect to the base end. The warpage amount L1 (see FIG. 14) is about 5 mm.

  The case 131 of the buzzer module 130 has a box shape, and a mounting portion 132 is projected from one surface of the case 131. A mounting portion 132 of the buzzer module 130 is bonded to the base plate 110. In this state, a gap S (see FIG. 13B) is formed between the case 131 of the buzzer module 130 and the base plate 110. The first strip plate portion 123, the second strip plate portion 124, and the third strip plate portion 125 of the urging steel plate 120 are inserted into the gap S. That is, the fitting recess 122 of the urging steel plate 120 is fitted into the fitting ridge 112 of the base plate 110, and at the same time, the gap S between the case 131 of the buzzer module 130 and the base plate 110 is inserted into the urging steel plate 120. The 1st strip board part 123, the 2nd strip board part 124, and the 3rd strip board part 125 are inserted.

  A push button switch 133 is provided in the case 131 of the buzzer module 130. When the base plate 110, the urging steel plate 120, and the buzzer module 130 are assembled and assembled to the window glass 5, the third band plate portion 125 of the urging steel plate 120 presses the push button switch 133 by an elastic force. Yes. In this state, the push button switch 133 is in an off state. As described above, in the attached state, the push button switch 133 of the buzzer module 130 is being pushed. At this time, the warping amount L1 in FIG. 14 is zero mm.

  The detection tool 100 is urged by its own elasticity at a position where the first and second strips 123 and 124 of the urging steel plate 120 are displaced in the plane of the window glass 5. Then, when the window glass 5 is broken, the entire window glass 5 is cracked as shown in FIG. Along with this, the detection tool 100 detects breakage of the window glass 5 by crushing in a partial region of the window glass 5 as shown in FIGS. At this time, the urging steel plate 120 returns to its original shape. When the shape of the urging steel plate 120 is restored, the buzzer module 130 is lifted and the push button switch 133 is opened. When the push button switch 133 is opened, an alarm sound is output from the speaker of the buzzer module 130 (a buzzer sounds).

The present embodiment is not limited to the above, and may be embodied as follows, for example.
Although the X-arm type window regulator is used as the window regulator, a cable-type window regulator may be used. Further, the driving means is not limited to one having a motor, but may be one manually operated by an occupant.

  The clip 40 and the buzzer module 50 (the detection tool 100 and the buzzer module 130) may be attached to an openable glass roof provided on the rear door or the roof in addition to the side door in the passenger car.

  -Although the clip 40 was installed in the lower end part of the window glass 5, you may install not only in this but in the lower part in the side surface of the window glass 5, for example. In short, what is necessary is just to install in the place which is not conspicuous inside the vehicle door 1 among the edge parts of a window glass.

The clip 40 (detection tool 130) may be attached to a fixed (fitting type) window glass instead of the openable window glass.
Although the identification sound is added to the warning sound, the fraud detection identification sound may be added to the warning sound by AM modulation. Further, the fraud detection identifying sound may be added to the warning sound by FM modulation. Further, the fraud detection identification sound may be an ultrasonic wave (the identification sound was an audible sound, but may be an ultrasonic wave).

  At this time, a piezoelectric speaker may be used. That is, when an identification sound is added (superimposed) to an alarm sound, an audible range or an ultrasonic wave can be transmitted as the identification sound by using a piezoelectric speaker.

  ・ While window glass breakage (glass breakage) has been detected, instead of this, it may be possible to detect unauthorized door release or unauthorized hood release, or even a system that detects that the vehicle body has been damaged. Good.

  In FIG. 2, the band-pass filter 62, the buzzer sound determination circuit 64, and the AND gate 66 in the glass breakage determination circuit 60 may be omitted, and the discrimination signal determination circuit 65 passes through the band-pass filter 63 after being converted into an electrical signal by the microphone 61. The identification sound may be determined and sent to the security ECU 70 as the identification sound.
