[Problems to be solved by the invention]
However, in the conventional alarm device using audio equipment, the volume is increased or the direction of the speaker is changed. Therefore, there is a tendency for the alarm sound to be heard in the vehicle interior. It was difficult to tell theft.
[0006]
The present invention has been made in view of these problems, and it is possible to effectively notify the outside of a vehicle of an illegal act (theft of a vehicle) by an unauthorized intruder using a sound reproducing device effectively at a high volume. An object of the present invention is to provide a possible vehicle warning system and warning device.
[0007]
[Means for Solving the Problems]
In the alarm system according to claim 1, which has been made to achieve the above object, the alarm sound reproduction control means causes the sound reproduction device to reproduce the alarm sound when the detection means detects an unauthorized entry into the vehicle interior. The sound reproduction device is connected to a speaker provided in the vehicle interior, and receives sound commands from the alarm sound reproduction control means and performs sound reproduction (reproduction of alarm sound) using the speaker. Further, the alarm system of the present invention is provided with a window opening and closing device capable of opening and closing a vehicle window, and when the detection means detects an unauthorized entry into the vehicle interior, the window opening control means Allow the device to open the vehicle window.
[0008]
In the alarm system according to claim 1 configured as described above, since the alarm sound is reproduced from the sound reproducing device through the speaker in the vehicle compartment in a state where the window is opened, the alarm sound is not generated in the vehicle compartment, The alarm sound is effectively transmitted from the vehicle interior to the vehicle exterior through the window opening. Therefore, according to this alarm system, it is possible to notify a person around the vehicle of an unauthorized intrusion caused by theft of the vehicle at a louder volume than before. As a result, according to this alarm system, it is possible to make it difficult for illegal intruders to continue illegal activities (vehicle theft).
[0009]
The alarm system according to the present invention may use a dedicated sound reproducing device for the alarm system. However, if a general-purpose sound reproducing device is used, the alarm system according to the present invention can be constructed at low cost. As a general-purpose sound reproduction device, for example, a radio reception / reproduction device capable of receiving and reproducing radio broadcast signals, various sound data can be read out from a medium (compact disc, cassette tape, hard disk, etc.) on which sound data is recorded and reproduced. Such as a playback device.
[0010]
However, the general-purpose sound reproduction device described above is configured to be user-operable, and configured to perform sound reproduction based on user operation information input to the sound reproduction device from the outside (operation unit). It is common. For this reason, when a general-purpose sound reproducing device that can be operated by the user is used in the alarm system of the present invention, the sound reproducing device can be operated by an unauthorized intruder even if the sound reproducing device reproduces the alarm sound by the alarm sound reproducing control means. Thus, there is a possibility that the reproduction of the alarm sound is stopped.
[0011]
Therefore, when using a user-operable sound reproduction device as the sound reproduction device of the alarm system, the alarm sound reproduction control means may be configured as described in claim 2.
The alarm sound reproduction control means in the alarm system according to claim 2 causes the sound reproduction apparatus to reproduce the alarm sound and invalidates the user operation on the sound reproduction apparatus when the detection means detects an unauthorized entry into the vehicle interior. The sound reproduction stop operation based on user operation information is prohibited.
[0012]
According to the alarm system of claim 2 configured as described above, it is possible to prevent the alarm sound from being stopped by an unauthorized intruder even when a user-operable sound reproducing device is used. . As a result, while illegal acts are being carried out in the passenger compartment by unauthorized intruders, the sound reproduction device can continue to play alarm sounds, and illegal acts (theft of vehicles) by unauthorized intruders can be continued. Can be difficult. Moreover, such an alarm system can be constructed at a low cost.
[0013]
In addition, an electric window opening / closing device represented by a power window device such as an automobile is usually configured to be operated by the user, and a user operation input to the window opening / closing device from the outside (operation unit). Based on the information, the vehicle window is opened and closed. Therefore, when such a window opening / closing device is used as the window opening / closing device of the alarm system, the window opening control means may be configured as described in claim 3.
[0014]
The window opening control means in the alarm system according to claim 3 opens the window of the vehicle to the window opening and closing device and invalidates the user operation on the window opening and closing device when the detecting means detects an unauthorized entry into the vehicle interior. The window is closed based on user operation information.
[0015]
According to the alarm system of claim 3 configured as described above, even if a window opening / closing device operable by the user is used, the window opened by the window opening control means is operated by an unauthorized intruder. It can be prevented from being closed. As a result, while illegal activities are being carried out by unauthorized intruders in the passenger compartment, the windows can be opened and the alarm sound is transmitted to the outside at a loud volume. Continuation of theft) can be made difficult.
[0016]
By the way, when the passenger compartment is hot, an unauthorized intruder cannot withstand the heat and has a high possibility of opening a window or door of the vehicle. Therefore, when there is an unauthorized intrusion into the vehicle interior, the window opening control means does not open the window to the window opening / closing device, and if the vehicle interior is heated to a high temperature, Doors can be opened.
[0017]
Therefore, when constructing an alarm system, the vehicle is provided with an air conditioner capable of adjusting the temperature in the passenger compartment, and instead of the window opening control means, the temperature adjusting means is provided as in claim 4. Also good.

That is, in this alarm system, when an unauthorized intrusion is detected, the alarm sound is reproduced by the sound reproducing device using the speaker in the vehicle interior, and the interior of the vehicle interior is heated by the operation of the air conditioner. .
[0018]
Therefore, in the alarm system according to the fourth aspect, it is expected that the intruder cannot withstand the temperature in the passenger compartment and that the doors and windows are voluntarily opened. When the door or window is opened, an alarm sound is effectively transmitted from the passenger compartment to the outside of the vehicle through the opening of the window. Therefore, in the alarm system according to the fourth aspect, it is possible to notify the person around the vehicle of the illegal action at a louder volume than before, and to make it difficult for illegal intruders to continue the illegal action.
[0019]
In the present invention (Claim 4), similarly to the alarm system according to Claim 1, the alarm system can be constructed at low cost by using a general-purpose sound reproducing device.
However, if a general-purpose sound reproduction device that can be operated by the user is used, even if an alarm sound is reproduced from the speaker by the alarm sound reproduction control means, the sound reproduction device is operated by an unauthorized intruder and the reproduction of the alarm sound is stopped. If the user-operable sound reproduction device is used as the sound reproduction device of the alarm system according to claim 4, the alarm sound reproduction control means is used as the alarm reproduction device according to claim 2. A configuration similar to that of the sound reproduction control means may be used. According to the alarm system of claim 5 configured as described above, it is possible to prevent the alarm sound from being stopped by an unauthorized intruder.
[0020]
An air conditioner mounted in an automobile or the like is generally configured to be operable by a user, and the temperature in the passenger compartment is determined based on user operation information input to the air conditioner from the outside (operation unit). It is configured to adjust. Therefore, when such an air conditioner is used as the air conditioner of the alarm system, the temperature adjusting means may be configured as described in claim 6.
[0021]
The temperature adjusting means in the alarm system according to claim 6, when the detecting means detects an unauthorized entry into the vehicle interior, causes the air conditioner to adjust the temperature of the vehicle interior to a high temperature and invalidates a user operation on the air conditioner. Thus, the vehicle interior temperature control based on user operation information is prohibited.
[0022]

[0034]
By the way, when the start command signal for the anti-theft mode is input from the operation panel 11, the control unit 21 of the alarm device 20 in the present embodiment executes the anti-theft process shown in FIG. 2. FIG. 2 is a flowchart showing an anti-theft process executed by the control unit 21.
[0035]
When the anti-theft process is started, the control unit 21 monitors the output signal from the detection device 13 to determine whether the detection device 13 detects an unauthorized intrusion into the vehicle interior (S110). If it is determined that no unauthorized intrusion into the passenger compartment has been detected (No in S110), it is determined whether or not an anti-theft mode cancel command has been input from the operation panel 11 (S115). At the time of accepting the release command, for example, as a pre-processing, a password is requested from the user in order to identify whether or not the user is a valid user.
[0036]
If the control unit 21 determines that an anti-theft mode release command has been input (Yes in S115), the anti-theft process ends. On the other hand, if it is determined that the release command has not been input (No in S115), the process returns to S110, and it is determined again whether the intruding action into the vehicle compartment is detected by the detection device 13.
[0037]
If it is determined that an illegal intrusion into the vehicle interior has been detected (Yes in S110), the control unit 21 transmits a theft detection signal to the power window device 30 using the transmission / reception unit 25, and the power window device 30. The vehicle window is opened (S120).
