When the display device displays a screen prompting the setting of the alarm hold time, or the first notification unit outputs a voice prompting the setting of the alarm hold time, the occupant receives information on the alarm hold time from the input device (not shown). Enter. The input device is, for example, a display device or a microphone included in the car navigation device. For example, the occupant may input a time such as X minutes, or may input an end time of the alarm hold time such as Y hours and YY minutes.
The reception unit 15 receives the information regarding the alarm hold time input by the occupant.
The reception unit 15 outputs information regarding the received alarm hold time to the setting unit 16.

The setting unit 16 sets the alarm holding time based on the information regarding the alarm holding time received by the reception unit 15. Specifically, for example, when the information regarding the alarm holding time is information of a time such as X minutes, the setting unit 16 sets the X minutes as the alarm holding time. Further, for example, when the information regarding the alarm holding time is the information of the end time of the alarm holding time such as Y hour YY minute, the setting unit 16 sets the time from the current time to the end time as the alarm holding time. Set.

In the second embodiment, it is possible to set an upper limit on the alarm holding time and limit the range of the alarm holding time that can be set by the setting unit 16. The upper limit of the alarm holding time is set in advance by, for example, a developer or the like, and is stored in a place where the control unit 14 and the setting unit 16 can refer to it. The developer or the like sets, for example, the upper limit of the alarm hold time in consideration of the generally acceptable time.

When the alarm hold time based on the information about the alarm hold time received by the reception unit 15 exceeds the preset upper limit, the setting unit 16 makes it impossible to set the alarm hold time and does not set the alarm hold time. In this case, the setting unit 16 provides, for example, information to the display device provided in the car navigation device that the information regarding the alarm holding time cannot be received and information for prompting the re-input of the information regarding the alarm holding time. Display it. Further, for example, the setting unit 16 causes the first notification unit to output a voice indicating that the input information regarding the alarm hold time cannot be accepted and a voice prompting the re-input of the information regarding the alarm hold time. May be good. The occupant operates the input device to re-enter the information regarding the alarm hold time.
In this way, even if the occupant inputs information regarding the alarm hold time for which the upper limit is to be set, the vehicle alarm device 1 cannot set the alarm hold time. Therefore, the entered alarm hold time Information about is not accepted.

When the alarm hold time is set, the setting unit 16 temporarily stores the set alarm hold time in the storage unit (not shown). The storage unit may be, for example, a memory included in the vehicle alarm device 1a, or may be provided in a place outside the vehicle alarm device 1a where the vehicle alarm device 1a can be referred.
Further, when the alarm hold time is set, the setting unit 16 notifies the control unit 14 that the alarm hold time has been set.

Lock instruction of the control unit 14 When the setting unit 16 notifies that the alarm hold time has been set, the lock instruction control unit 141 sends instruction information for permitting the door lock operation of the vehicle to the door lock control unit 2. Output.
Then, the control unit 14 waits until the door lock-related information acquisition unit 112 acquires the door lock-related information instructing the unlock operation of the door of the vehicle.
When the alarm holding time elapses without outputting the door lock-related information instructing the unlock operation of the vehicle door from the door lock-related information acquisition unit 112, the notification control unit 142 of the control unit 14 via the communication unit 17. Then, an alarm is output to the second notification unit. The second notification unit is, for example, a speaker provided in a mobile terminal carried by an occupant. For example, the notification control unit 142 causes the second notification unit to output an electronic sound or a voice for notifying that the alarm target living body is left in the vehicle. The notification control unit 142 causes the second notification unit to output an electronic sound or voice, and causes the display device provided in the mobile terminal to display a message indicating that the alarm target living body is left in the vehicle. You may. The notification control unit 142 of the control unit 14 may output an alarm to an external device capable of outputting an alarm via the communication unit 17.
The control unit 14 may determine that the alarm hold time has elapsed based on the alarm hold time temporarily stored in the storage unit.

If the door lock-related information acquisition unit 112 outputs the door lock-related information instructing the unlocking operation of the vehicle door by the time the alarm hold time elapses, the lock instruction control unit 141 will move the door lock control unit 141. In response to 2, instruction information for permitting the unlock operation of the door is output, and the notification control unit 142 does not output an alarm.

When the alarm holding time is set, the setting unit 16 calls the first notification unit the information for alerting the living body to be alarmed to be left in the vehicle (hereinafter referred to as "alert information". ) Can be output. Specifically, the alert information is, for example, a message indicating the danger of the alarm target living body being left in the vehicle, or an alarm being output when the alarm hold time has elapsed. It is a description about the treatment to be performed. The setting unit 16 may display the attention-calling information on, for example, a display device included in the car navigation device.
When the setting unit 16 sets the alarm hold time, it outputs the alerting information to alert the occupant to leave the vehicle while the alarm target living body is left in the vehicle. It is possible to give the consciousness of returning to the vehicle after the alarm holding time and before the alarm is output.

The communication unit 17 is a communication interface device that transmits / receives information to / from an external device such as a mobile terminal carried by an occupant via a network.

The operation of the vehicle alarm device 1a according to the second embodiment will be described.
FIG. 5 is a flowchart for explaining the operation of the vehicle alarm device 1a according to the second embodiment.
In FIG. 5, since the specific operations of steps ST501 to ST507 are the same as the specific operations of steps ST201 to ST207 of FIG. 2 described in the first embodiment, duplicate description will be omitted. ..

In step ST504, when the biological identification unit 13 identifies the living body in the vehicle as the alarm target living body (when “YES” in step ST504), in other words, the biological identification unit 13 in the vehicle indicates the alarm target living body. As a result of identifying, when the target living body presence / absence information output to the control unit 14 indicates the existence of the alarm target living body, the lock instruction control unit 141 causes the receiving unit 15 to accept the alarm holding time. The reception unit 15 receives the information regarding the alarm hold time input by the occupant (step ST508).
The reception unit 15 outputs information regarding the received alarm hold time to the setting unit 16.

The setting unit 16 determines whether or not the alarm hold time can be set based on the information regarding the alarm hold time received by the reception unit 15 in step ST508 (step ST509).
If the setting unit 16 cannot set the alarm hold time in step ST509 (when “NO” in step ST509), the process proceeds to step ST506. In step ST509, the case where the setting unit 16 could not set the alarm hold time is specifically the case where the reception unit 15 does not output the information regarding the alarm hold time, or the reception unit 15 outputs the information. This is a case where the alarm hold time based on the information on the alarm hold time exceeds the upper limit of the alarm hold time, and the reception unit 15 does not accept the re-input of the information on the alarm hold time from the occupant.

When the setting unit 16 sets the alarm holding time in step ST509 (when “YES” in step ST509), the setting unit 16 notifies the control unit 14 that the alarm holding time has been set, and the control unit 14 notifies the control unit 14. The lock instruction control unit 141 outputs instruction information for permitting the door lock operation to the door lock control unit 2 (step ST510). As a result, the door of the vehicle is locked by the door lock control unit 2. That is, the occupant can lock the door of the vehicle and can leave the vehicle. Here, the occupant leaves the vehicle.

Then, the control unit 14 determines whether or not the door lock-related information acquisition unit 112 has acquired the door lock-related information instructing the unlock operation of the door of the vehicle. Specifically, the control unit 14 determines whether or not the information indicating that the door lock-related information for instructing the unlock operation of the vehicle door has been acquired has been output from the door lock-related information acquisition unit 112 (step). ST511).
If the door lock related information acquisition unit 112 does not output information indicating that the door lock related information for instructing the unlock operation of the vehicle door has been acquired in step ST511 (when “NO” in step ST511), control is performed. The notification control unit 142 of the unit 14 determines whether or not the alarm hold time has elapsed (step ST512).
If the alarm hold time has not elapsed in step ST512 (when “NO” in step ST512), the control unit 14 returns to step ST511, and again from the door lock related information acquisition unit 112, of the vehicle door. It is determined whether or not the information indicating that the door lock related information instructing the unlock operation has been acquired is output.

When the alarm holding time has elapsed in step ST512 (when “YES” in step ST512), the notification control unit 142 causes the second notification unit to output an alarm via the communication unit 17 (step). ST513). After that, the control unit 14 returns to step ST511, and again determines whether or not the information indicating that the door lock-related information acquisition unit 112 has acquired the door lock-related information instructing the unlock operation of the vehicle door is output. judge.
That is, when the occupant returns to the vehicle and the alarm holding time elapses without instructing the door unlock operation of the vehicle, the notification control unit 142 causes the second notification unit to output an alarm, and then the occupant causes the occupant to output an alarm. Unless the vehicle returns to the vehicle and instructed to unlock the door of the vehicle, the output of the alarm from the second notification unit will continue. As a result, the vehicle warning device 1a does not return to the vehicle in that state, even though the occupant recognizes that the warning target living body is left in the vehicle beyond the warning holding time. It is possible to prevent the vehicle from being away from the vehicle.

On the other hand, in step ST511, when the door lock related information acquisition unit 112 outputs information to the effect that the door lock related information instructing the door unlock operation of the vehicle has been acquired (in the case of "YES" in step ST511). ), The lock instruction control unit 141 of the control unit 14 outputs instruction information for permitting the unlock operation of the vehicle door to the door lock control unit 2, and ends the process. As a result, the door of the vehicle is unlocked by the door lock control unit 2. At this time, if the notification control unit 142 has output an alarm to the second notification unit, the notification control unit 142 stops the output of the alarm.

After performing the process of step ST505, or after the lock instruction control unit 141 outputs the instruction information for permitting the unlock operation of the vehicle door to the door lock control unit 2 in step ST511, At the end of the process, the control unit 14 initializes the alarm hold time temporarily stored in the storage unit. The control unit 14 initializes the alarm holding time by, for example, deleting the stored alarm holding time information. Further, for example, the control unit 14 may initialize the alarm holding time at the start of the operation as shown in FIG.

In this way, when the occupant instructs the door lock operation to move away from the stopped vehicle, the vehicle alarm device 1a can set the alarm hold time when the alarm target living body exists in the vehicle. When the alarm hold time can be set, the vehicle door is locked based on the instruction of the occupant to lock the door. Further, when the alarm holding time elapses, the vehicle alarm device 1a outputs an alarm to the second notification unit via the communication unit 17, and after the alarm output, the occupant returns to the vehicle and unlocks the vehicle door. Unless an operation instruction is given, the output of the alarm is continued. As a result, the vehicle warning device 1a allows the occupant to temporarily leave the vehicle while leaving the warning target living body in the vehicle, but the warning target living body is left unattended beyond the warning holding time. It is possible to prevent the occupant from returning to the vehicle without returning to the vehicle while recognizing that the vehicle is in the state of being present.

FIG. 6 shows, in the second embodiment, the occupant 200 leaves the vehicle 30 by setting the alarm hold time in a state where the alarm target living body is left in the vehicle 30, and the vehicle 30 has passed the alarm hold time. It is a figure for demonstrating the image of an example of the operation of the vehicle warning device 1a when the door unlock operation of a vehicle 30 is not instructed without returning to.
In FIG. 6, the same reference numerals are given to the same configurations as those described with reference numerals in FIG.

Now, as shown in FIG. 6, with the child 201 seated on the child car seat 102, the occupant 200 sets the alarm hold time in the stopped vehicle 30, and sets it after leaving the vehicle 30. It is assumed that the alarm hold time has passed.
Then, in the vehicle alarm device 1a, the control unit 14 holds the alarm without outputting the information indicating that the door lock related information acquisition unit 112 has acquired the door lock related information instructing the unlock operation of the door of the vehicle 30. Judge that time has passed. Then, the notification control unit 142 of the control unit 14 causes the second notification unit 301 included in the mobile terminal 300 carried by the occupant 200 to output an alarm via the communication unit 17. Even after the notification control unit 142 outputs an alarm from the second notification unit 301 of the mobile terminal 300, the door lock-related information acquisition unit 112 has acquired the door lock-related information instructing the unlock operation of the door of the vehicle 30. Unless the information of is output, the notification control unit 142 continues to output the alarm.

As a result, even if the occupant 200 can temporarily leave the vehicle 30 with the child 201 left in the vehicle 30, the child 201 remains left in the state where the alarm holding time is exceeded. While recognizing that, the state of being away from the vehicle 30 cannot be continued, and the vehicle returns to the vehicle. As described above, the vehicle warning device 1a allows the occupant to temporarily leave the vehicle while the warning target living body is left in the vehicle, but the warning target living body remains in the left state. While recognizing, it is possible to prevent the occupant from continuing to leave the vehicle for a certain period of time and to return the occupant to the vehicle.

As described above, according to the second embodiment, the vehicle warning device 1a locks the door after the stop information acquisition unit 111 acquires the vehicle stop information in addition to the configuration of the vehicle warning device 1 according to the first embodiment. When the related information acquisition unit 112 acquires the door lock related information instructing the door lock operation and the presence / absence information of the target living body output by the biological identification unit 13 indicates the existence of the target living body for alarm, the alarm holding time When the setting unit 16 sets the alarm hold time, the control unit 14 permits the door lock operation based on the door lock related information, and outputs an alarm until the alarm hold time elapses. Was configured to hold. Therefore, the vehicle warning device 1a recognizes that the occupant is allowed to temporarily leave the vehicle while the warning target living body is left in the vehicle, but the warning target living body remains in the left state. However, it is possible to prevent the occupant from staying away from the vehicle for a certain period of time and to return the occupant to the vehicle.

Embodiment 3.
In the second embodiment, the upper limit of the alarm holding time set by the vehicle alarm device 1a is fixed to a time determined in advance by the developer or the like.
In the third embodiment, an embodiment in which the upper limit of the alarm holding time can be appropriately changed will be described.

FIG. 7 is a diagram showing a configuration example of the vehicle alarm device 1b according to the third embodiment.
In FIG. 7, with respect to the same configuration as the vehicle alarm device 1a described with reference to FIG. 4 in the second embodiment, the same reference numerals are given and duplicate description will be omitted.
The vehicle alarm device 1b according to the third embodiment is different from the vehicle alarm device 1a according to the second embodiment in that it includes a temperature information acquisition unit 18.
The specific operation of the setting unit 16 is different between the vehicle alarm device 1a according to the second embodiment and the vehicle alarm device 1b according to the third embodiment. The specific operation of the setting unit 16 of the vehicle alarm device 1b according to the third embodiment will be described later.

The temperature information acquisition unit 18 acquires information indicating the outside air temperature of the vehicle (hereinafter referred to as “temperature information”).
Specifically, the temperature information acquisition unit 18 acquires, for example, information on the outside air temperature measured by a temperature sensor (not shown) provided in the vehicle as the temperature information. It should be noted that this is only an example, and the temperature information acquisition unit 18 may be able to acquire temperature information indicating the outside air temperature of the vehicle.
The temperature information acquisition unit 18 outputs the acquired temperature information to the setting unit 16.

The setting unit 16 changes the upper limit of the alarm holding time according to the temperature information acquired by the temperature information acquisition unit 18.
For example, even if the upper limit of the alarm holding time set in advance by the developer or the like is 60 minutes, the outside air temperature of the vehicle based on the temperature information acquired by the temperature information acquisition unit 18 is 30 ° C. or higher, or below freezing point. If, the setting unit 16 changes the upper limit of the alarm holding time to 10 minutes. As a result, for example, in the hot sun or in the extremely cold condition, the setting unit 16 sets the alarm hold time only up to 10 minutes. Since the setting unit 16 does not set the alarm hold time exceeding 10 minutes, when the occupant tries to set the alarm hold time exceeding 10 minutes, the alarm hold time is not accepted and the alarm hold time is set. Cannot be set. If the occupant temporarily leaves the vehicle while leaving the alarm target living body in the vehicle, he / she has no choice but to set an alarm hold time of 10 minutes or less.
In addition, it is assumed that the upper limit of the alarm holding time when the setting unit 16 has an outside air temperature is determined in advance.

Therefore, for the operations described with reference to FIG. 5, the same step numbers are assigned and duplicate explanations are omitted.

In step ST504, when the biological identification unit 13 identifies the living body in the vehicle as the alarm target living body (when “YES” in step ST504), in other words, the biological identification unit 13 determines the alarm target living body in the vehicle. As a result of identifying, when the target living body presence / absence information output to the control unit 14 indicates the existence of the alarm target living body, the temperature information acquisition unit 18 acquires the temperature information indicating the outside air temperature of the vehicle (step ST5041).
The temperature information acquisition unit 18 acquires temperature information based on, for example, the control of the control unit 14. When the biometric identification unit 13 notifies that the biological body to be alarmed has been identified, the control unit 14 causes the temperature information acquisition unit 18 to acquire the temperature information.

The setting unit 16 changes the upper limit of the alarm holding time according to the temperature information acquired by the temperature information acquisition unit 18 in step ST5041 (step ST5042).
When the setting unit 16 changes the upper limit of the alarm holding time in step ST5042, for example, after performing the processing of step ST505 and ending the processing, the control unit 14 sets the upper limit of the alarm holding time. It is recommended to return to the upper limit of the alarm hold time set in advance by the developer or the like.

In this way, the vehicle alarm device 1b can change the upper limit of the time during which the occupant can temporarily leave the vehicle to be alarmed while leaving the living body to be alarmed in the vehicle, depending on the outside air temperature. Therefore, the vehicle alarm device 1b promptly returns the occupant to the vehicle when the temperature inside the vehicle rises or falls rapidly in a short time due to the high outside air temperature of the vehicle or the low outside air temperature of the vehicle. Can be made to.

In the above-described third embodiment, the setting unit 16 may change the upper limit of the alarm holding time in consideration of the current weather in addition to the temperature information acquired by the temperature information acquisition unit 18. For example, the time required for the temperature inside the vehicle to rise or fall until it reaches an abnormal temperature varies depending on the weather. The setting unit 16 may acquire information on the current weather from, for example, a database (not shown) outside the vehicle alarm device 1b in which the weather information is stored.

Further, in the above-described third embodiment, the setting unit 16 changes the upper limit of the alarm holding time according to the temperature information acquired by the temperature information acquisition unit 18, but the setting unit 16 is not limited to this. , The upper limit of the alarm hold time can be changed according to other conditions.
For example, the setting unit 16 can change the upper limit of the alarm holding time according to the type of the alarm target organism, which is the alarm target organism identified by the biometric identification unit 13. In this case, the biometric identification unit 13 can identify the type of the living body to be alarmed. The biometric identification unit 13 can identify the type of the living body to be alarmed by using, for example, a known image processing technique based on the image in the vehicle taken by the camera. The biometric identification unit 13 may identify the type of the alarm target living body by using some known technique.

To give a specific example, for example, even if the upper limit of the alarm holding time set in advance by the developer or the like is 60 minutes, when the biometric identification unit 13 identifies the infant, the setting unit 16 sets the alarm holding time. The alarm hold time is changed so that the upper limit of is 10 minutes. It is assumed that the time for which the setting unit 16 changes the upper limit of the alarm holding time is set in advance by the alarm target living body identified by the biometric identification unit 13. The setting unit 16 determines how long the upper limit of the alarm holding time should be changed in consideration of, for example, the outside air temperature or the weather, in addition to the type of the alarm target living body identified by the biometric identification unit 13. You may.
In this way, even if the setting unit 16 changes the upper limit of the alarm holding time according to the type of the alarm target living body identified by the biometric identification unit 13, the vehicle alarm device 1b promptly sends the occupant to the vehicle. You can make it go back.

As described above, according to the third embodiment, the vehicle alarm device 1b is a temperature information acquisition unit 18 that acquires temperature information indicating the outside air temperature of the vehicle in addition to the configuration of the vehicle alarm device 1a according to the second embodiment. The setting unit 16 is configured to change the upper limit of the alarm holding time according to the temperature information acquired by the temperature information acquisition unit 18. Therefore, the vehicle warning device 1b allows the occupant to temporarily leave the vehicle while the warning target living body is left in the vehicle, but the warning target living body is left unattended for a certain period of time. While recognizing that, it is possible to prevent the vehicle from leaving the vehicle without returning to the vehicle in that state.

In the above-described first to third embodiments, the vehicle warning devices 1, 1a and 1b are subject to warning in the vehicle when the vehicle door lock operation is instructed after the vehicle is stopped. If a living body exists, the lock operation of the door of the vehicle is not permitted until the living body subject to the alarm no longer exists in the vehicle or the alarm holding time is set.
However, the present invention is not limited to this, and for example, in the vehicle warning devices 1, 1a and 1b, when the vehicle door lock operation is instructed after the vehicle is stopped, the living body to be alarmed exists in the vehicle. Even so, if there is a living body other than the warning target living body in addition to the alarm target living body, the lock operation of the vehicle door may be permitted.

Specifically, in the vehicle alarm devices 1, 1a, 1b, the biological detection unit 12 first detects a living body existing in the vehicle. When a plurality of living bodies are present in the vehicle, the biometric detection unit 12 detects the plurality of living bodies and outputs information about the plurality of living bodies to the biometric identification unit 13 for each of the detected plurality of living bodies.
The biometric identification unit 13 identifies whether or not each of the plurality of living organisms is an alarm target living body based on the information regarding the plurality of living organisms output from the biometric detection unit 12.
As a result of identifying the alarm target organism in the vehicle, the biological identification unit 13 determines that all of the plurality of organisms detected in the vehicle are the alarm target organisms, and the presence / absence information of the target organism indicating the existence of the alarm target organism. Is output to the control unit 14. Further, when the biological identification unit 13 identifies one of the plurality of living organisms detected in the vehicle as a result of identifying the living body to be alarmed in the vehicle, even one living body is not a living body to be alarmed. The presence / absence information of the target living body indicating the absence of the alarm target living body is output to the control unit 14.
Lock instruction of control unit 14 After the stop information acquisition unit 111 acquires vehicle stop information, the door lock-related information acquisition unit 112 acquires door lock-related information instructing a vehicle door lock operation. When the presence / absence information of the target living body output by the living body identification unit 13 indicates the existence of the living body to be alarmed, the door based on the door lock related information received by the door lock control unit 2 with respect to the door lock control unit 2. Outputs instruction information that disallows the lock operation of.
Further, in the lock instruction control unit 141, after the stop information acquisition unit 111 acquires the vehicle stop information, the door lock related information acquisition unit 112 acquires the door lock related information instructing the vehicle door lock operation, and also When the target living body presence / absence information output by the living body identification unit 13 indicates the absence of the target living body to be alarmed, the door based on the door lock related information received by the door lock control unit 2 with respect to the door lock control unit 2. Outputs instruction information that allows the lock operation of.
If there is a living body that is not the alarm target living body, in other words, a living body that can open the door by itself and go out of the vehicle, there is no problem even if the alarm target living body exists in the vehicle. This is because it can be considered.
