The invention described in Patent Document 1 issues an alarm when an infant left in a car is exposed to danger, but it cannot prevent infants from being exposed to dangerous situations.

The present invention has been made in consideration of the above circumstances, and aims to provide an alarm device, an alarm method, and a program that can warn the driver in advance to prevent a living body left in the vehicle from being put in a dangerous situation.

In order to solve the above problem, the alarm device according to the present invention is characterized by including, for example, a living body detection unit that detects whether or not a living body other than the driver is present inside the vehicle, an in-vehicle speaker provided in the passenger compartment of the vehicle, an alighting detection unit that detects whether or not the driver has performed an action to prepare to alight, and an alarm command unit that outputs a first alarm from the in-vehicle speaker when the action to prepare to alight is detected.

An alarm method according to another aspect of the present invention is characterized by including, for example, a step of detecting whether or not a living body other than the driver is present inside the vehicle, a step of detecting whether or not the driver has performed an action to prepare to disembark, and a step of outputting a first alarm from an in-vehicle speaker provided in the passenger compartment of the vehicle when the action to prepare to disembark is detected.

A program relating to another aspect of the present invention is characterized in that it causes a computer to function, for example, as a living body detection unit that detects whether or not a living body other than the driver is present inside the vehicle, a disembarkation detection unit that detects whether or not the driver has performed an action to prepare to disembark, and an alarm command unit that outputs a first alarm from an in-vehicle speaker provided in the passenger compartment of the vehicle when the action to prepare to disembark is detected.
The computer program can be provided by downloading via a network such as the Internet, or can be provided by recording it on various computer-readable recording media such as a CD-ROM.

In any of the above aspects of the present invention, when a living body other than the driver is present inside the vehicle and the driver prepares to exit the vehicle, a first alarm is output from the in-vehicle speaker. This allows the driver to be warned in advance so that the living body left in the vehicle does not fall into a dangerous situation.

The vehicle may include a temperature sensor that measures the temperature inside the vehicle cabin, and an air conditioning status detection unit that detects whether the air conditioning unit of the vehicle is operating. When the measurement result of the temperature sensor is equal to or higher than a threshold value and the air conditioning unit is not operating, the alarm command unit may output a voice from the in-vehicle speaker as the first alarm, urging the driver to operate the air conditioning unit. This makes it possible to urge the driver to operate the air conditioning unit. By having the driver operate the air conditioning unit, measures can be taken in advance to prevent passengers from suffering from heatstroke, etc.

The vehicle may include an exterior speaker provided outside the vehicle, the alighting detection unit detects whether the driver has alighted from the vehicle, and the alarm command unit may output a second alarm different from the first alarm from the exterior speaker when the alighting operation is detected. This makes it possible to prompt the driver who has alighted to return to the vehicle compartment.

The vehicle may include a communication unit that communicates with a mobile device, and the alarm command unit may output the second alarm to the mobile device via the communication unit. This allows the driver to be notified that a living body may be in a dangerous state even if the driver who has disembarked misses the second alarm output from the exterior speaker.

The vehicle may also be provided with a door lock control unit that unlocks the vehicle doors and releases a child lock that prevents the rear seat door of the vehicle from being opened from the inside when the second alarm is output. This allows a living body in the vehicle compartment to get out on its own, and also allows a person outside the vehicle to rescue a living body from the vehicle compartment.

The vehicle may include an environment detection unit that detects the internal environment of the vehicle cabin, and the alarm command unit may output a third alarm, different from the first alarm and the second alarm, from the exterior speaker when an abnormal environment in the vehicle cabin is detected by the environment detection unit after outputting the second alarm. This makes it possible to notify people around the vehicle of a danger to a living body.

A window control unit may be provided that opens the vehicle window when the third alarm is output. This can encourage people outside the vehicle to rescue a living body inside the vehicle.

The present invention makes it possible to warn the driver in advance so that a living body left in the vehicle does not get into a dangerous situation.

The following describes in detail an embodiment of an alarm device according to the present invention with reference to the drawings. The alarm device outputs an alarm to prevent children, animals, etc. left behind in the vehicle cabin from being exposed to danger.

Figure 1 is a diagram showing an outline of an alarm device 1 according to this embodiment, a vehicle 2 in which the alarm device 1 is installed, and a mobile terminal 3 connected to the alarm device 1. Figure 2 is a diagram showing an outline of the electrical function blocks of the alarm device 1, the vehicle 2, and the mobile terminal 3. The alarm device 1 is connected to the mobile terminal 3 wirelessly or via a network.

An in-vehicle speaker 31 is provided inside the vehicle interior 30, and an exterior speaker 32 is provided outside the vehicle 2. The vehicle 2 is equipped with an air conditioner 33 that adjusts the temperature of the vehicle interior 30. The vehicle 2 is also equipped with windows 34 and doors 35.

The warning device 1 mainly includes a control unit 10, an infrared sensor 21, and an environment detection unit 22. The vehicle 2 mainly includes an in-vehicle speaker 31, an exterior speaker 32, an air conditioner 33, a window 34, and a door 35.

The infrared sensor 21 (corresponding to the living body detection unit of the present invention) is, for example, an infrared sensor that uses the pyroelectric effect of ceramics, and detects infrared rays emitted from living bodies such as humans and animals. This makes it possible to detect whether or not a living body is present in the vehicle interior 30. The infrared sensor 21 can also detect the position where the living body is present. Therefore, it can detect whether or not a living body other than the driver D (passenger P, pets, etc.) is present in the vehicle interior 30. The infrared sensor 21 can use known technology.

The living body detection unit that detects a living body is not limited to the infrared sensor 21. For example, an imaging unit that captures an image of the vehicle interior 30 may be provided, and the control unit 10 may detect a living body based on the captured image, thereby functioning as the living body detection unit.

The environment detection unit 22 is a sensor that detects the internal environment of the vehicle 2. The environment detection unit 22 mainly has a temperature sensor 23 and a gas sensor 24.

The temperature sensor 23 is provided in the vehicle interior 30 and measures the temperature of the vehicle interior 30. The gas sensor 24 is provided in the vehicle interior 30 and includes a sensor that detects the concentration of carbon monoxide and a sensor that detects the concentration of carbon dioxide. The temperature sensor 23 and the gas sensor 24 can use known technology.

The control unit 10 has at least an air conditioning status detection unit 11, a window control unit 12, a door lock control unit 13, an alighting detection unit 14, an alarm command unit 15, and a communication unit 16 as software resources, using a calculation device such as a CPU (Central Processing Unit) 56 (see FIG. 3) for executing information processing and a storage device 54 (see FIG. 3).

The air conditioning status detection unit 11 is a functional unit that detects whether the air conditioning device 33 of the vehicle 2 is operating. The air conditioning status detection unit 11 is connected to a control unit (not shown) of the vehicle 2 that controls the air conditioning device 33, and obtains information on whether the air conditioning device 33 is operating from the control unit of the vehicle 2.

In addition, the air conditioning status detection unit 11 acquires the operable time of the air conditioning unit 33 when the air conditioning unit 33 is operating. The control unit (not shown) of the vehicle 2 can calculate the operable time of the air conditioning unit 33 based on the power consumption of the air conditioning unit 33 and the remaining charge of the battery (not shown) of the vehicle 2. The control unit (not shown) of the vehicle 2 may calculate the operable time of the air conditioning unit 33 based on the power consumption of the air conditioning unit 33 and the remaining charge of the fuel of the vehicle 2. The air conditioning status detection unit 11 acquires the operable time of the air conditioning unit 33 calculated by the control unit (not shown) of the vehicle 2.

The window control unit 12 is connected to the window 34 and is a functional unit that opens the window 34. Specifically, the window control unit 12 opens and closes the window 34 via a window drive unit (not shown) that the window 34 has.

The door lock control unit 13 is connected to the doors 35 (including the driver's door 35A and the rear seat door 35B) and is a functional unit that unlocks the doors 35 and releases the child lock that prevents the rear seat door 35B from being opened from the inside.

The disembarking detection unit 14 is a functional unit that detects whether the driver D has performed a disembarking preparation action or a disembarking action. The disembarking detection unit 14 is connected to the driver's door 35A or a sensor (not shown) provided near the driver's door 35A, and detects whether the driver's door 35A is open or closed. The disembarking detection unit 14 is also connected to a pressure sensor (not shown) provided in the driver's seat (not shown) provided in the passenger compartment 30, and detects whether the driver D is sitting in the driver's seat.

Then, when the driver's door 35A is open and the driver D is sitting in the driver's seat, the disembarking detection unit 14 detects that the driver D has performed an action to prepare to disembark. Then, when the driver's door 35A is open and the driver D is not sitting in the driver's seat, the disembarking detection unit 14 detects that the driver D has performed an action to disembark.

The alarm command unit 15 is a functional unit that outputs an alarm from the in-vehicle speaker 31 or the exterior speaker 32. The alarm command unit 15 outputs a first alarm from the in-vehicle speaker 31, and outputs a second alarm or a third alarm from the exterior speaker 32. The first alarm, second alarm, and third alarm are output at different times and have different contents. The function of the alarm command unit 15 will be described in detail later.

The communication unit 16 is a functional unit that communicates with the mobile terminal. The communication unit 16 outputs the second alarm output from the alarm command unit 15 to the mobile terminal 3.

Figure 3 is a block diagram showing an example of the hardware configuration of the alarm device 1. The alarm device 1 includes a control device 50, a communication device 52, and a storage device 54. The control device 50 is mainly configured with a CPU (Central Processing Unit) 56 and a memory 58.

In the control device 50, the CPU executes a specific program stored in the storage device 54 or memory 58, etc., to function as various functional units.

The communication device 52 is configured with a communication interface for communicating with an external device. The communication device 52 transmits and receives various information to and from, for example, the mobile terminal 3.

The storage device 54 is composed of a hard disk or the like. This storage device 54 stores various programs and information necessary for executing processing in the control device 50, as well as information on the processing results.

The alarm device 1 can be realized using an information processing device such as a dedicated or general-purpose server computer. The alarm device 1 may be configured from a single information processing device, or may be configured from multiple information processing devices distributed over a communication network. FIG. 3 shows only a portion of the main hardware configuration of the alarm device 1, and the alarm device 1 may be equipped with other configurations that are generally equipped in a server device.

Figures 4 and 5 are flowcharts showing the flow of processing performed by the alarm device 1. First, the processing for the disembarking preparation action shown in Figure 4 will be described. First, the alarm command unit 15 judges whether or not the driver D has performed the disembarking preparation action based on the detection result by the disembarking detection unit 14 (step SP11). If the driver D has not performed the disembarking preparation action (NO in step SP11), the processing of step SP11 is repeated.

When the driver D has prepared to disembark (YES in step SP11), the alarm command unit 15 determines whether or not a living body other than the driver D is present in the vehicle compartment 30 based on the detection result of the infrared sensor 21 (step SP12). When a living body other than the driver D is not present in the vehicle compartment 30 (NO in step SP12), the process returns to step SP11.

If a living body other than the driver D is present in the vehicle interior 30 (YES in step SP12), the alarm command unit 15 outputs a first alarm from the vehicle speaker 31 (step SP13). The process of step SP13 will be described below.

The warning command unit 15 obtains the measurement result from the temperature sensor 23. The air conditioning state detection unit 11 detects whether the air conditioning device 33 is operating, and the warning command unit 15 obtains the detection result from the air conditioning state detection unit 11. As a result, if the temperature of the passenger compartment 30 measured by the temperature sensor 23 is equal to or higher than the first threshold value and the air conditioning device 33 is not operating, the warning command unit 15 outputs a voice prompting the operation of the air conditioning device 33 as a first warning from the in-vehicle speaker 31. The content of the first warning in this case is, for example, voice information such as "There is a risk of heat stroke. Please turn on the air conditioner." As a result, the temperature in the passenger compartment 30 is rising, and the driver D who has performed the disembarking preparation operation is warned of the risk of heat stroke, and the driver D is prompted to operate the air conditioning device 33. Then, by having the driver D operate the air conditioning device 33, it is possible to take measures in advance to prevent the passenger P from suffering from heat stroke.

In addition, when the temperature of the passenger compartment 30 measured by the temperature sensor 23 is equal to or lower than the second threshold value and the air conditioning device 33 is not operating, the alarm command unit 15 outputs a voice from the in-vehicle speaker 31 as a first alarm urging the driver to operate the air conditioning device 33. The content of the first alarm in this case is, for example, voice information such as "The temperature is low, please turn on the air conditioner." This makes it possible to warn the driver D who has prepared to disembark that the temperature in the passenger compartment 30 is too low, and urge the driver D to operate the air conditioning device 33.

The warning command unit 15 obtains the detection result of whether or not the air conditioner 33 is operating from the air conditioning status detection unit 11, and determines whether or not the air conditioner 33 is operating (step SP14).

If the air conditioner 33 is operating (YES in step SP14), the warning command unit 15 obtains the remaining operation time of the air conditioner 33 via the air conditioning status detection unit 11 and outputs this from the in-vehicle speaker 31 (step SP15). Note that in step SP15, the warning command unit 15 may output the remaining operation time of the air conditioner 33 from the in-vehicle speaker 31 if the remaining operation time of the air conditioner 33 is less than a threshold value (e.g., 3 hours). This makes it possible to inform the driver D that the remaining operation time of the air conditioner 33 is short.

After the air conditioning device 33's operable time is output from the in-vehicle speaker 31 (step SP15) or if the air conditioning device 33 is not in operation (NO in step SP14), the warning command unit 15 determines whether or not the driver D has disembarked based on the detection result from the disembarking detection unit 14 (step SP16). If the driver D has not disembarked (NO in step SP16), the process returns to step SP11. If the driver D has disembarked (YES in step SP16), the warning command unit 15 performs the process for the disembarking action shown in FIG. 5.

As shown in FIG. 5, when driver D gets off the vehicle (YES in step SP15), the alarm command unit 15 outputs a second alarm, which is different from the first alarm output in step SP13, from the exterior speaker 32 (step SP21). At this stage, driver D is outside the vehicle, so the alarm is output from the exterior speaker 32 so that driver D can hear the alarm.

The content of the second warning may be, for example, audio information such as "There is someone still inside. There is a risk of heat stroke." This can prompt the driver D who has disembarked to return to the vehicle compartment 30.

The alarm command unit 15 also outputs a second alarm to the mobile terminal 3 via the communication unit 16 (step SP21). This allows the driver D, who has disembarked, to be informed of the danger to the passenger P even if he or she misses the second alarm output from the exterior speaker 32. Note that it is not essential to output the second alarm to the mobile terminal 3 in step SP21.

The alarm command unit 15 also unlocks the door 35 via the door lock control unit 13 and releases the child lock that prevents the rear seat door 35B from being opened from the inside (step SP22).

Next, the warning command unit 15 determines whether the environment of the vehicle interior 30 is abnormal based on the detection result by the environment detection unit 22 (step SP23). For example, the warning command unit 15 obtains the measurement result from the temperature sensor 23, and when the room temperature is equal to or higher than the third threshold, determines that the environment is such that the passenger P may suffer from heat stroke, i.e., that the environment of the vehicle interior 30 is abnormal. The third threshold may be the same as the first threshold or may be greater than the first threshold. Also, for example, the warning command unit 15 may determine that the environment of the vehicle interior 30 is abnormal when the room temperature is equal to or higher than the third threshold and the air conditioning device 33 is not operating.

For example, the alarm command unit 15 determines that the environment of the vehicle interior 30 is abnormal when the room temperature measured by the temperature sensor 23 is equal to or lower than the fourth threshold. The fourth threshold may be the same as the second threshold or may be smaller than the second threshold.

For example, the alarm command unit 15 acquires the measurement results from the gas sensor 24, and when the carbon monoxide concentration in the passenger compartment 30 is equal to or higher than a threshold value, the alarm command unit 15 determines that the environment is such that the passenger P may become ill with carbon monoxide, i.e., that the environment in the passenger compartment 30 is abnormal. For example, the alarm command unit 15 acquires the measurement results from the gas sensor 24, and when the carbon dioxide concentration in the passenger compartment 30 is equal to or higher than a threshold value, the alarm command unit 15 determines that the environment is such that the passenger P may become ill, i.e., that the environment in the passenger compartment 30 is abnormal.

If no abnormal environment is detected in the vehicle interior 30 (NO in step SP23), the process of step SP23 is repeated.

If an abnormal environment is detected in the passenger compartment 30 (YES in step SP23), the alarm command unit 15 outputs a third alarm, which is different from the first alarm output in step SP13 and the second alarm output in step SP21, from the exterior speaker 32 (step SP24). The content of the third alarm is, for example, audio information saying, "There is someone inside, so open the windows and doors." This makes it possible to notify people around the vehicle 2 of the danger posed by the passenger P.

The content of the third alarm may be, for example, audio information saying, "There is someone inside, please open the door." This can prompt people around vehicle 2 to open the door of vehicle 2.

In addition, a third alarm stating "There is someone inside, so open the windows and doors" is output from the exterior speaker 32, and the alarm command unit 15 opens the windows 34 via the window control unit 12 (step SP24). This reduces the risk of heatstroke for the passenger P in the vehicle compartment 30.

In step SP24, the process of opening the window 34 is not essential. In particular, if it is determined in step SP23 that the environment of the vehicle interior 30 is abnormal because the room temperature measured by the temperature sensor 23 is equal to or lower than the fourth threshold, it is desirable not to open the window 34 because the outside air temperature may be low.

The alarm command unit 15 may also output a third alarm to the mobile terminal 3 via the communication unit 16. This can prompt the driver D to return to the vehicle 2.

According to this embodiment, when the driver D's preparation for getting off the vehicle is detected, the first alarm is output from the in-vehicle speaker 31, thereby informing the driver D that he is getting off the vehicle and leaving the passenger P behind in the vehicle compartment 30. Therefore, the driver can be warned to prevent a living body left in the vehicle compartment from falling into a dangerous situation. In addition, it is possible to prevent the passenger P from being left behind unintentionally.

In addition, according to this embodiment, when the room temperature is equal to or higher than the first threshold value and the air conditioner 33 is not operating, a sound urging the driver to operate the air conditioner 33 is output as a first alarm from the in-vehicle speaker 31, thereby warning the driver D who has prepared to disembark of the risk of heat stroke and urging the driver D to operate the air conditioner 33. Then, by having the driver D operate the air conditioner 33, measures can be taken in advance to prevent the passenger P from suffering from heat stroke.

In addition, according to this embodiment, when the driver D gets off the vehicle, a second alarm different from the first alarm is output from the exterior speaker 32, so that the driver D who has got off can be urged to return to the vehicle compartment 30. In addition, by outputting the second alarm to the mobile terminal 3, even if the driver D who has got off misses hearing the second alarm output from the exterior speaker 32, the driver can be informed that the passenger P may be in a dangerous situation.

In addition, according to this embodiment, after the second alarm is output, the door 35 is unlocked and the child lock on the rear seat door 35B is released, allowing the passenger P in the vehicle interior 30 to get out on his or her own, and a person outside the vehicle can rescue the passenger P from the vehicle interior 30.

In addition, according to this embodiment, if an abnormal environment is detected in the vehicle interior 30 after the second alarm is output, a third alarm is output from the exterior speaker 32, thereby urging people outside the vehicle to rescue the passenger P.

In this embodiment, if a living body is present in the vehicle interior 30 (YES in step 12), the alarm command unit 15 outputs the first alarm from the in-vehicle speaker 31 when a predetermined condition is satisfied in step SP13 (for example, when the temperature of the vehicle interior 30 measured by the temperature sensor 23 is equal to or higher than the first threshold value or equal to or lower than the second threshold value and the air conditioning device 33 is not operating). However, the first alarm may also be output from the in-vehicle speaker 31 when the predetermined condition is not satisfied. That is, in step SP13, the alarm command unit 15 may output the first alarm from the in-vehicle speaker 31 when a living body is present in the vehicle interior 30 (YES in step 12).

In addition, in this embodiment, after the first alarm is output from the in-vehicle speaker 31 (step SP13), it is determined whether the air conditioner 33 is operating (step SP14), but the order of steps SP13 and SP14 may be reversed. In this case, if the air conditioner 33 is operating (YES in step SP14), the alarm command unit 15 outputs the first alarm from the in-vehicle speaker 31 (step SP13) after or at the same time as outputting the drivable time of the air conditioner 33 from the in-vehicle speaker 31 (step SP15).

In this embodiment, after outputting the second alarm (step SP21), the alarm command unit 15 unlocks the door 35 and the child lock on the rear seat door 35B in step SP22. However, the door 35 and the child lock on the rear seat door 35B may be unlocked when the air conditioning unit 33 is not operating, or the door 35 and the child lock on the rear seat door 35B may be unlocked when the temperature in the passenger compartment 30 is equal to or higher than a threshold value. In addition, after outputting the second alarm (step SP21), an abnormality in the passenger compartment 30 may be detected (step SP23), and when an abnormality in the passenger compartment 30 is detected (YES in step SP23), the door 35 may be unlocked and the child lock on the rear seat door 35B may be released (step SP22), and the windows may be opened and the third alarm may be output from the exterior speaker 32 (step SP24).

The embodiment of the present invention has been described above in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes and the like that do not deviate from the gist of the present invention are also included.
