[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, like components are designated by like reference numerals, and the description thereof will be omitted as appropriate.

[0017] 1 is a functional block diagram showing an overview of a processing system 10 according to a first embodiment. The processing system 10 includes a stop detection unit 11, a reference value registration unit 12, an abandonment detection unit 13, and a storage unit 14. Note that the processing system 10 does not necessarily have to include the storage unit 14. In this case, an external device configured to be able to communicate with the processing system 10 includes the storage unit 14.

[0018] The stop detection unit 11 acquires parking position information indicating the parking position of the vehicle. The stop detection unit 11 then compares the position indicated by the parking position information with a pre-registered registration area to detect a stop event that stops the use of the vehicle. The reference value registration unit 12 registers the CO ２ The abandoned vehicle detection unit 13 detects the CO concentration inside the vehicle after the stop event is detected and registers the concentration as a reference value in the storage unit 14. ２ By comparing the concentration with a reference value registered in the memory unit 14, it is possible to detect whether a living thing has been left behind in the vehicle.

[0019] In this way, the processing system 10 detects a stop event that stops the use of the vehicle by comparing the parking position of the vehicle with a pre-registered registered area. Specifically, the condition for detecting a stop event is that "the parking position of the vehicle is within a registered area." Then, the processing system 10 measures the CO2 inside the vehicle after the stop event is detected. ２ Based on the concentration, the abandonment of a living organism in a vehicle is detected.

[0020] According to this processing system 10, the process of detecting whether a living creature has been left behind in a vehicle is executed only when the vehicle is parked in a pre-registered registered area. By appropriately registering the registered area, the process of detecting whether a living creature has been left behind in a vehicle can be executed at an appropriate time, thereby preventing the inconvenience of executing the process at an unnecessary time. For example, parking lots that the user regularly uses or parking lots of facilities such as shopping malls where the user tends to park for relatively long periods of time can be registered as registered areas. Furthermore, a user who sometimes parks their vehicle nearby and waits in the vehicle until their child comes out when taking their child to or from cram school or extracurricular activities can choose not to register that location as a registered area.

[0021] The processing system 10 of this embodiment solves the problem of executing a process for detecting whether a living thing has been left behind in a vehicle at an appropriate timing.

[0022] 2 is a functional block diagram showing an overview of a processing system 10 according to a second embodiment. The processing system 10 includes a stop detection unit 11, a reference value registration unit 12, an abandonment detection unit 13, a storage unit 14, an alighting detection unit 15, and a reference value update unit 16. The processing system 10 does not necessarily have to include the storage unit 14. In this case, an external device configured to be able to communicate with the processing system 10 includes the storage unit 14.

[0023] The stop detection unit 11 detects a stop event that stops the use of the vehicle based on a sensor mounted on the vehicle. The reference value registration unit 12 registers the CO ２ The CO concentration in the vehicle is registered as a reference value in the storage unit 14. The vehicle dismounting detection unit 15 detects a vehicle dismounting event based on a sensor mounted on the vehicle. When a vehicle dismounting event is detected after a stop event, the reference value update unit 16 updates the reference value registered in the storage unit 14 to the CO concentration in the vehicle at the time the vehicle dismounting event was detected. ２ The abandoned vehicle detection unit 13 updates the CO concentration inside the vehicle after the stop event is detected. ２ By comparing the concentration with a reference value registered in the memory unit 14, it is possible to detect whether a living thing has been left behind in the vehicle.

[0024] In this manner, the processing system 10 may, in response to detecting a stop event, measure the CO2 inside the vehicle at that time. ２ The concentration is registered as a reference value, and upon detection of a subsequent exit event, the reference value is calculated based on the CO ２ The processing system 10 then updates the reference value to the concentration. The processing system 10 then detects whether a living organism has been left behind on a vehicle based on the latest reference value. By updating the reference value using this method and detecting whether a living organism has been left behind on a vehicle based on the reference value, false detections can be reduced. The reason for this is explained below.

[0025] CO inside the vehicle detected by the sensor ２As an example of a method for detecting whether a living thing has been left behind in a vehicle based on the concentration, the method shown in Fig. 3 can be considered. In Fig. 3, the horizontal axis represents time, and the vertical axis represents CO2 concentration inside the vehicle. ２ A graph of the concentration is shown.

[0026] In this method, when a stop event that stops the use of the vehicle is detected, the CO ２ The concentration is the reference value. ２ Concentration minus the reference value (CO ２ If the concentration increase value exceeds a threshold, it is determined that a living thing has been left behind in the vehicle.

[0027] In this method, there is a risk that a living creature may be mistakenly determined to have been left behind in a vehicle in the following cases.

[0028] In this case, after a stop event is detected, an occupant intentionally stays in the vehicle with the doors and windows closed, and then gets out of the vehicle, leaving no living creatures in the vehicle. The reason why a misjudgment occurs in such a case will be explained using FIG. 4 .

[0029] 4 shows a flow in which a passenger gets off the vehicle after a stop event is detected (the "get-off event" shown in the figure). In this case, the CO ２ The concentration continues to rise due to the occupant intentionally remaining in the vehicle. When the occupant exits the vehicle, the CO concentration inside the vehicle detected by the sensor increases. ２ However, as shown in Figure 4, the increase in CO concentration does not stop immediately after the passengers get off the vehicle, but may stop after a while. This phenomenon may occur depending on the size of the vehicle, the amount of CO concentration inside the vehicle, etc. ２ This is due to uneven concentration and the sensor mounting position.

[0030] FIG. 4 thus illustrates the CO2 buildup inside the vehicle due to an occupant intentionally remaining in the vehicle after a stop event is detected. ２ After the concentration has risen to a certain level, the CO inside the vehicle remains high even after the passengers get out of the vehicle. ２As shown in Figure 4, the CO concentration inside the vehicle after the passengers get out of the vehicle continues to increase for a while. ２ The increase in concentration increases the CO inside the vehicle detected by the sensor. ２ If the value obtained by subtracting the reference value from the concentration exceeds the threshold, it may be erroneously determined that an organism has been left behind in the vehicle.

[0031] In addition, depending on the disembarkation event, the CO ２ A method for stopping the concentration-based abandonment detection can also be considered, but in this case, if another living thing is left in the vehicle after the disembarking event, the abandonment cannot be detected.

[0032] To address this issue, the processing system 10 of this embodiment, as shown in FIG. 5, detects a stop event and then calculates the CO ２ The concentration is registered as a reference value, and upon detection of a subsequent exit event, the reference value is calculated based on the CO ２ After the vehicle exit event is detected, the processing system 10 updates the CO concentration inside the vehicle. ２ The value obtained by subtracting the updated reference value from the concentration (CO ２ When the CO concentration (increase in CO concentration) exceeds a threshold, it is determined that a living thing has been left behind in the vehicle. ２ Even if the increase in concentration continues for a while, the increase during this period will not affect the CO2 inside the vehicle detected by the sensor. ２ This can prevent the problem of the value obtained by subtracting the reference value from the concentration exceeding the threshold value.

[0033] In this way, according to the processing system 10 of this embodiment, CO ２ The problem of suppressing erroneous determinations in detecting whether a living organism has been left behind in a vehicle based on concentration is solved.

[0034] Third Embodiment "Overview" The processing system 10 of the third embodiment is a specific implementation of the processing system 10 of the first embodiment. That is, the processing system 10 detects a stop event that stops the use of the vehicle by comparing the parking position of the vehicle with a pre-registered registration area. Then, the processing system 10 calculates the CO2 inside the vehicle after the stop event is detected. ２ Based on the concentration, the abandoned living thing in the vehicle is detected. This will be explained in detail below.

[0035] 6 shows an overall view of a system including a processing system 10. As shown in the figure, the processing system 10 cooperates with an in-vehicle system 20 and a management system 30 to execute predetermined processes.

[0036] The in-vehicle system 20 is a system mounted on a vehicle. The vehicle may be, but is not limited to, a bus, a car, a truck, a train, or the like. The vehicle may be a human-driven vehicle. The vehicle may also be an autonomous vehicle.

[0037] The in-vehicle system 20 includes at least various sensors mounted at any position on the vehicle and a means for collecting information indicating measurements taken by the various sensors and vehicle status and transmitting the information to the processing system 10. Examples of the vehicle status include, but are not limited to, the engine status (ON / OFF), the power status (ON / OFF), and the door lock status (open / closed). The in-vehicle system 20 may include an ECU (Electronic Control Unit). Signals from the various sensors and switches are input to the ECU.

[0038] Various sensors are ２ Measure the concentration of CO ２ Examples of the various sensors include a temperature sensor that measures temperature, a camera (image sensor) that captures images, and a door sensor that detects whether a vehicle door is open or closed. Other examples of the various sensors include a weight sensor that detects whether a person is sitting in a seat, and a position sensor (GPS (Global Positioning System) sensor) that measures the current position of the vehicle. Note that the various sensors are not limited to those exemplified here.

[0039] The processing system 10 detects a stop event that stops the use of the vehicle based on the information received from the in-vehicle system 20. Then, the processing system 10 calculates the CO 2 inside the vehicle after the stop event is detected. ２ Based on the concentration, the processing system 10 detects whether a living thing has been left behind in the vehicle. The processing system 10 transmits the results of various calculations to the management system 30. The specific configuration of the processing system 10 will be described later.

[0040] The management system 30 is a system installed in a management center. The management system 30 outputs information received from the processing system 10 via various output devices. The output devices include, but are not limited to, a display, a speaker, a projector, a printer, etc.

[0041] A monitor is stationed at the management center and monitors the information output by the management system 30. For example, when the processing system 10 detects that a vehicle has been abandoned, information indicating this is output from the management system 30. The output information includes the location information of the vehicle where the abandonment was detected, the date and time when the abandonment was detected, the elapsed time since the stop event was detected, the current state of the interior of the vehicle (CO ２ The information may include information such as the concentration, temperature, etc. The monitor can take appropriate action based on such information. Examples of the action include, but are not limited to, contacting a contact (telephone number, email address, etc.) that is registered in advance and associated with the vehicle, or dispatching a worker to the location of the vehicle.

[0042] "Hardware Configuration" An example of the hardware configuration of the processing system 10 will be described. Each functional unit of the processing system 10 is realized by any combination of hardware and software. Those skilled in the art will understand that there are various variations in the realization method and device. Software includes programs that are pre-loaded when the device is shipped, and programs downloaded from recording media such as CDs (Compact Discs) or servers on the Internet.

[0043] FIG. 7 is a block diagram illustrating an example of the hardware configuration of a processing system 10. As shown in FIG. 7, the processing system 10 has a processor 1A, a memory 2A, an input / output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. The processing system 10 does not necessarily have to have the peripheral circuit 4A. Note that the processing system 10 may be composed of multiple devices that are physically and / or logically separated. In this case, each of the multiple devices can have the above hardware configuration.

[0044] The bus 5A is a data transmission path for the processor 1A, memory 2A, peripheral circuit 4A, and input / output interface 3A to mutually transmit and receive data. The processor 1A is, for example, a processing unit such as a CPU or a graphics processing unit (GPU). The memory 2A is, for example, a random access memory (RAM) or a read-only memory (ROM). The input / output interface 3A includes interfaces for acquiring information from input devices, external devices, external servers, external sensors, cameras, etc., and interfaces for outputting information to output devices, external devices, external servers, etc. The input / output interface 3A also includes an interface for connecting to a communication network such as the Internet. Examples of input devices include a keyboard, mouse, microphone, physical buttons, touch panel, etc. Examples of output devices include a display, speaker, printer, mailer, etc. The processor 1A can issue commands to each module and perform calculations based on the results of those calculations.

[0045] "Functional Configuration" Next, the functional configuration of the processing system 10 of this embodiment will be described in detail. FIG. 1 shows an example of a functional block diagram of the processing system 10. As shown in the figure, the processing system 10 has a stop detection unit 11, a reference value registration unit 12, an abandonment detection unit 13, and a storage unit 14. Note that the processing system 10 does not necessarily have to have the storage unit 14. In this case, an external device configured to be able to communicate with the processing system 10 has the storage unit 14.

[0046] The stop detection unit 11 acquires parking position information indicating the parking position of the vehicle. Then, the stop detection unit 11 detects a stop event that stops the use of the vehicle by comparing the position indicated by the parking position information with a pre-registered registration area. Below, the process of acquiring the parking position information and the process of detecting a stop event will be explained separately.

[0047] - Acquisition of parking position information - "Parking position information" is information indicating the position of the vehicle when a parking-related event is detected. The parking position information is vehicle position information (GPS information, etc.) acquired at the position of the vehicle when the parking-related event is detected.

[0048] A "parking-related event" includes at least one of the following: - A process of stopping the vehicle engine - A process of turning off the power to the vehicle - A door lock process based on a predetermined locking operation that locks the vehicle doors from outside the vehicle - An event in which the position of the vehicle does not change for a predetermined period of time or more - No one is in the driver's seat

[0049] The "vehicle engine stop process" is a process in which the vehicle engine is switched from ON to OFF. This process can be detected based on information handled by the in-vehicle system 20.

[0050] The "vehicle power-off process" is a process in which the vehicle power is switched from ON to OFF. This process can be detected based on information handled by the in-vehicle system 20.

[0051] The "door locking process based on a predetermined locking operation for locking the vehicle doors from outside the vehicle" is a process for locking the doors based on an operation on a smart key or a sensor located outside the vehicle (e.g., on the door handle). This process can be detected based on information handled by the in-vehicle system 20. For example, the data input to the system may include information identifying the input method (e.g., input from a smart key, input from a sensor located outside the vehicle).

[0052] The "event in which the vehicle position does not change for a predetermined period of time" is detected based on the current position of the vehicle detected by a position sensor mounted on the vehicle. The predetermined period of time is a predetermined value.

[0053] "No one in the driver's seat" is detected based on an image generated by a weight sensor for detecting whether a person is sitting in the driver's seat or a camera for photographing the driver's seat. For example, if the weight detected by the weight sensor is below a threshold, it is determined that no one is in the driver's seat. Also, if no person is captured in a predefined area (the area where the driver's seat is located) in the image generated by the camera, it is determined that no one is in the driver's seat.

[0054] The stop detection unit 11 acquires parking position information indicating the position of the vehicle when the above-described parking-related event is detected. The detection of the parking-related event may be performed by the stop detection unit 11. That is, the stop detection unit 11 may acquire various information for detecting the above-described parking-related event from the in-vehicle system 20 through real-time processing, and detect the parking-related event based on the acquired information. Alternatively, the detection of the parking-related event may be performed by the in-vehicle system 20. Then, the detection result may be transmitted from the in-vehicle system 20 to the processing system 10.

[0055] - Detection of a stop event - If the location indicated by the parking position information is included in a pre-registered registered area, the stop detection unit 11 determines that a stop event that stops the use of the vehicle has occurred (detection of a stop event). In this embodiment, the conditions for detecting a stop event are the above-mentioned "detection of a parking-related event" and "the location indicated by the parking position information being included in a pre-registered registered area." A stop event is an event that triggers processing executed by the reference value registration unit 12 and the abandonment detection unit 13.

[0056] There are various methods for registering the registration area. For example, the registration area is registered by at least one of the following registration methods 1 to 3.

[0057] Registration Method 1 In registration method 1, a registration area is registered for each vehicle. Specifically, the stop detection unit 11 registers a registration area for each vehicle based on a user input.

[0058] The user input may be, for example, an address. In this case, the area corresponding to the address is registered as the registered area. The address to be input may include the street address, such as "1-2-3, XX-cho, XX-city, XX-prefecture." Alternatively, the address to be input may specify the prefecture or city, ward, town, or village without including the street address, such as "XX prefecture," "XX city, XX prefecture," or "XX-cho, XX-city, XX-prefecture." The area specified by the input information is registered as the registered area.

[0059] Alternatively, the user input may be an input specifying a predetermined point on a map. In this case, a predetermined area identified based on the specified point is registered as a registered area. For example, the stop detection unit 11 may register a circle with a radius R [m] centered on the specified point as the registered area. The value of the radius R may be freely set by the user or may be predetermined.

[0060] The process of receiving the user input as described above for each vehicle and registering the registration point may be realized using any technology, such as, but not limited to, an app or a web page.

[0061] Registration Method 2 In registration method 2, a registration area is registered for each vehicle. Specifically, the stop detection unit 11 registers a registration area for each vehicle based on the past position history of each vehicle.

[0062] This method is based on the premise that a history of past positions of each vehicle is registered. The history is registered by repeatedly acquiring and registering the current position of the vehicle using a GPS sensor mounted on the vehicle.

[0063] The stop detection unit 11 registers a location where a person has been present for a predetermined period of time or more in the past as a registered area. Alternatively, the stop detection unit 11 may register a location where a person has been present for a predetermined period of time or more in the past while no one was present in the driver's seat as a registered area. As described above, the absence of a person in the driver's seat can be identified based on, for example, a weight sensor or an image generated by a camera that photographs the driver's seat.

[0064] For example, the stop detection unit 11 may register, as a registered area, a predetermined area identified based on a location where a person has previously been present for a predetermined period of time or more, or a location where a person has previously been present for a predetermined period of time without a person in the driver's seat. Specifically, the stop detection unit 11 may register, as a registered area, a circle having a radius R [m] centered on the location. The value of the radius R may be freely set by the user or may be predetermined. The predetermined time may be a fixed value that is predetermined. Furthermore, the predetermined time may be freely changeable by the user.

[0065] Registration Method 3: In Registration Method 3, a registration area that is applicable to all vehicles is registered. In Registration Method 3, for example, facilities that are visited by an unspecified number of people and tend to have relatively long stay times (parking times), such as shopping malls and amusement parks, are registered as registration areas.

[0066] For example, these facilities are registered as registered areas by input by an operator or manager of the processing system 10. The registration method is the same as in the first registration method.

[0067] When detecting a stop event in a certain vehicle (target vehicle), the stop detection unit 11 determines whether the location indicated by the parking position information acquired in relation to the target vehicle is within a registered area associated with the target vehicle. Alternatively, the stop detection unit 11 may determine whether the location indicated by the parking position information acquired in relation to the target vehicle is within a registered area commonly applied to all vehicles.

[0068] Then, if the stop detection unit 11 determines that the location indicated by the parking location information acquired in relation to the target vehicle is within the registered area, it determines that a stop event that stops the use of the vehicle has occurred in the target vehicle.

[0069] In addition, if the stop detection unit 11 determines that the location indicated by the parking location information acquired in relation to the target vehicle is not within the registered area, it does not determine that a stop event that stops the use of the vehicle has occurred in the target vehicle.

[0070] Returning to FIG. 1, the reference value registration unit 12 calculates the CO ２ The CO concentration is registered as a reference value in the storage unit 14. FIG. 8 shows an example of information stored in the storage unit 14. In the example shown, the vehicle identification information and the reference value are linked to each other and registered. As described above, the vehicle has CO ２ Measure the concentration of CO ２ The sensor is installed. ２ The sensor measures the CO2 inside the vehicle when a stop event is detected. ２ The concentration is measured.

[0071] The abandoned vehicle detection unit 13 detects the CO ２ The concentration is compared with a reference value registered in the memory unit 14 to detect whether a living thing has been left behind in the vehicle. The living thing includes humans and other animals (dogs, cats, etc.).

[0072] Specifically, the abandoned vehicle detection unit 13 detects the CO ２ Concentration minus the reference value (CO ２ When the increase in the concentration of the living thing exceeds a threshold, it is determined that a living thing has been left behind in the vehicle. The threshold is a predetermined value. In the following embodiment, a means for setting the threshold for each vehicle will be described.

[0073] When the abandonment detection unit 13 detects that a living thing has been abandoned in a vehicle, it can perform a predetermined warning process.

[0074] For example, the abandonment detection unit 13 may transmit information indicating this to the management system 30. The information transmitted to the management system 30 may include location information of the vehicle where abandonment was detected, the date and time when abandonment was detected, the elapsed time since the stop event was detected, the current state of the interior of the vehicle (CO ２ Concentration, temperature, etc.) may also be included.

[0075] Additionally, the abandonment detection unit 13 may notify a contact that has been registered in advance in association with each vehicle. The notification may be realized by email, a push notification of an app, or the like. The information notified in the notification may include location information of the vehicle where abandonment was detected, the date and time when abandonment was detected, the elapsed time since the stop event was detected, the current state of the interior of the vehicle (CO ２ Concentration, temperature, etc.) may also be included.

[0076] Next, an example of the processing flow of the processing system 10 will be described with reference to the flowchart of FIG.

[0077] When the processing system 10 detects a stop event that stops the use of the vehicle (S10), the CO ２ The concentration is registered as a reference value (S11).

[0078] The processing system 10 then calculates the CO ２ By comparing the concentration with the reference value, whether or not a living thing has been left behind in the vehicle is detected (S12). Specifically, as shown in FIG. 3, the processing system 10 detects the CO 2 concentration inside the vehicle after the stop event is detected. ２ Concentration minus the reference value (CO ２ When the increase in the concentration of the vehicle exceeds a threshold, the processing system 10 determines that a living thing has been left behind in the vehicle. If the processing system 10 does not detect that a living thing has been left behind in the vehicle even after a predetermined time (a predetermined value) has elapsed since the detection of the stop event, the processing system 10 may end the process of detecting that a living thing has been left behind in the vehicle in S12. That is, in such a case, the processing system 10 determines that the "CO ２ The monitoring of "whether the value obtained by subtracting the reference value from the concentration exceeds the threshold value" may be terminated.

[0079] Here, an example of the flow of the process of detecting a stop event in S10 will be described with reference to the flowchart of FIG.

[0080] When the processing system 10 detects a parking-related event (Yes in S20), it acquires information indicating the position of the vehicle as parking position information (S21). The parking-related event includes at least one of a vehicle engine stop process, a vehicle power off process, a door lock process based on a predetermined locking operation that locks the vehicle doors from outside the vehicle, an event in which the position of the vehicle does not change for a predetermined period of time or more, and no one being in the driver's seat.

[0081] If the processing system 10 determines that the location indicated by the parking location information is within a pre-registered area (Yes in S22), it determines that a stop event that stops the use of the vehicle has occurred (S23). On the other hand, if the processing system 10 determines that the location indicated by the parking location information is not within a pre-registered area (No in S22), it does not determine that a stop event that stops the use of the vehicle has occurred.

[0082] The processing system 10 of this embodiment may include the means for updating the reference value described in the second embodiment.

[0083] "Effects" According to the processing system 10 of this embodiment, the same effects as those of the processing systems 10 of the first and second embodiments are realized.

[0084] Furthermore, according to the processing system 10 of this embodiment, the above-mentioned "detection of a parking-related event" and "the location indicated by the parking location information being included in a pre-registered area" can be set as conditions for detecting a stop event. By executing a process to detect whether a living creature has been left behind in a vehicle when such a stop event is detected, it is possible to prevent the inconvenience of executing the process at an unnecessary time.

[0085] Furthermore, according to the processing system 10 of this embodiment, it is possible to register a registration area using the various methods described above.

[0086] For example, the processing system 10 can register a registration area for each vehicle based on a user input. The user can freely register a desired location as a registration area.

[0087] Furthermore, the processing system 10 can register a registered area for each vehicle based on the past location history of each vehicle. For example, a location where a person has been present for a predetermined period of time or more in the past, or a location where a person has been present for a predetermined period of time or more in the past without a person in the driver's seat, can be registered as a registered area. If a living creature is left behind in a vehicle in such a location, there is a risk that the life of the living creature may be in danger. According to the processing system 10 of this embodiment, such important locations can be automatically registered for each vehicle.

[0088] Furthermore, the processing system 10 can register a registered area that is commonly applied to all vehicles. For example, facilities such as shopping malls and amusement parks that are visited by an unspecified number of people and tend to have relatively long stay times (parking times) are registered as registered areas. If a living creature is left behind in a vehicle in such a location, there is a risk that the life of the living creature may be in danger. According to the processing system 10 of this embodiment, such important locations can be registered as registered areas that are commonly applied to all vehicles.

[0089] Fourth Embodiment Overview The processing system 10 of the fourth embodiment is a specific implementation of the processing system 10 of the second embodiment. That is, the processing system 10 calculates the CO2 inside the vehicle at that time in response to the detection of a stop event. ２ The concentration is registered as a reference value, and upon detection of a subsequent exit event, the reference value is calculated based on the CO ２ The processing system 10 then updates the concentration of the living thing left behind in the vehicle based on the registered reference value. This will be described in detail below.

[0090] "Overall Image" The same as in the third embodiment.

[0091] "Hardware Configuration" The same as in the third embodiment.

[0092] "Functional Configuration" Next, the functional configuration of the processing system 10 of this embodiment will be described in detail. FIG. 2 shows an example of a functional block diagram of the processing system 10. As shown in the figure, the processing system 10 has a stop detection unit 11, a reference value registration unit 12, an abandonment detection unit 13, a storage unit 14, an alighting detection unit 15, and a reference value update unit 16. Note that the processing system 10 does not necessarily have to have the storage unit 14. In this case, an external device configured to be able to communicate with the processing system 10 has the storage unit 14.

[0093] The stop detection unit 11 detects a stop event that stops the use of the vehicle based on a sensor mounted on the vehicle. The stop detection unit 11 may detect the stop event using the method described in the third embodiment. Alternatively, the stop detection unit 11 may detect the parking-related event described in the third embodiment as a stop event. That is, when the parking-related event described in the third embodiment is detected, the stop detection unit 11 may determine that a stop event has occurred.

[0094] The configuration of the reference value registration unit 12 is the same as that described in the third embodiment.

[0095] The alighting detection unit 15 detects an alighting event in which a passenger alights from a vehicle based on a sensor mounted on the vehicle.

[0096] An "exit event" includes at least one of the following: Opening and closing a vehicle door Door locking processing based on a predetermined locking operation that locks the vehicle door from outside the vehicle Movement of a living thing in a predetermined direction in an image generated by a camera mounted on the vehicle

[0097] The "opening and closing of a vehicle door" is detected by a door sensor that is mounted on the vehicle and detects the opening and closing of the vehicle door. The exit detection unit 15 can detect this event based on information handled by the in-vehicle system 20.

[0098] The "door locking process based on a predetermined locking operation for locking the vehicle doors from outside the vehicle" is a process for locking the doors based on an operation on a smart key or a sensor located outside the vehicle (e.g., on the door handle). The exit detection unit 15 can detect this event based on information handled by the in-vehicle system 20.

[0099] "Movement of a living creature in a predetermined direction in an image generated by a camera mounted on a vehicle" is identified by image analysis. The movement of the living creature in a predetermined direction is movement to exit the vehicle through a door. The position of the vehicle door in the image generated by the camera and the direction of movement to exit the vehicle are defined in an image coordinate system and registered in the processing system 10. The camera is mounted on the vehicle at a position and orientation that allows it to capture an image of the vicinity of the vehicle door. The camera then captures video images.

[0100] The alighting detection unit 15 analyzes the image generated by the camera and detects a predetermined living thing within the image. The alighting detection unit 15 then tracks the living thing within the image and identifies the moving direction of the living thing within the image. The alighting detection unit 15 then determines that an alighting event has occurred when the living thing moves in a predefined moving direction for alighting and passes a predefined vehicle door position. Note that the conditions for detecting alighting through image analysis are not limited to the examples given here, and other conditions may also be used.

[0101] When a dismounting event is detected after a stop event, the reference value update unit 16 updates the reference value registered in the storage unit 14 by the CO ２ As mentioned above, the vehicle has CO ２ Measure the concentration of CO ２ The sensor is installed. ２ The sensor measures the CO2 inside the vehicle when an exit event is detected. ２ The concentration is measured.

[0102] 8, the reference value registration unit 12 associates the vehicle identification information and the reference value with each other and registers them in the storage unit 14. The reference value update unit 16 updates the reference value of each vehicle registered in this way to the CO ２ Update to concentration.

[0103] If a dismounting event is repeatedly detected after a stop event, the reference value update unit 16 updates the reference value registered in the storage unit 14 at that time in response to the detection of a new dismounting event by updating the reference value registered in the storage unit 14 to the CO ２ Update to concentration.

[0104] The abandoned vehicle detection unit 13 detects the CO ２ Abandonment of a living organism in a vehicle is detected by comparing the concentration with the reference value registered at that time in the memory unit 14. Until a dismounting event is detected, the abandonment detection unit 13 detects abandonment of a living organism in a vehicle based on the reference value registered by the reference value registration unit 12. After a dismounting event is detected, the abandonment detection unit 13 detects abandonment of a living organism in a vehicle based on the reference value updated by the reference value update unit 16.

[0105] The details of the process performed by the abandonment detection unit 13 are as described in the third embodiment.

[0106] Next, an example of the processing flow of the processing system 10 will be described with reference to the flowchart of FIG.

[0107] When the processing system 10 detects a stop event that stops the use of the vehicle (S30), the processing system 10 calculates the CO ２ The concentration is registered as a reference value (S31), and the processing system 10 then starts the reference value update process (S32).

[0108] An example of the flow of the update process in S32 will now be described with reference to the flowchart of FIG.

[0109] The processing system 10 waits for detection of an alighting event (S40). The alighting event includes at least one of opening and closing a vehicle door, a door lock process based on a predetermined locking operation for locking the vehicle door from outside the vehicle, and movement of a living thing in a predetermined direction in an image generated by a camera mounted on the vehicle.

[0110] When the processing system 10 detects a dismounting event (Yes in S40), the processing system 10 compares the reference value registered in the storage unit 14 with the CO 2 inside the vehicle at the time the dismounting event is detected. ２ Thereafter, the processing system 10 repeats the same process. That is, each time an alighting event is detected repeatedly, the processing system 10 updates the reference value registered in the storage unit 14 to the CO concentration inside the vehicle at the time the alighting event was detected. ２ Update to density (S41)

[0111] Returning to FIG. 11, the processing system 10 calculates the CO2 inside the vehicle after a stop event is detected. ２ The concentration is compared with the reference value registered in the memory unit 14 at that time to detect whether a living thing has been left behind in the vehicle (S33).

[0112] Specifically, after a stop event is detected, until a dismounting event is detected, the processing system 10 detects the abandonment of a living thing in a vehicle based on the reference value registered in response to the detection of the stop event, as shown in Fig. 3. The processing system 10 detects the abandonment of a living thing in a vehicle based on the reference value registered in response to the detection of the stop event, as shown in Fig. 3. ２ The concentration minus the reference value (CO ２ If the concentration increase value exceeds a threshold, it is determined that a living thing has been left behind in the vehicle.

[0113] After the dismounting event is detected, the processing system 10 detects the abandonment of a living thing in the vehicle based on the reference value updated in response to the detection of the dismounting event, as shown in Fig. 5. The processing system 10 detects the abandonment of a living thing in the vehicle based on the reference value updated in response to the detection of the dismounting event, as shown in Fig. 5. ２ The value obtained by subtracting the updated reference value from the concentration (CO ２ If the concentration increase value exceeds a threshold, it is determined that a living thing has been left behind in the vehicle.

[0114] If, after detecting a stop event, no disembarking event is detected and no living creature is detected left behind in the vehicle even after a predetermined time has passed, the processing system 10 may terminate the process of detecting a living creature left behind in the vehicle in S33.

[0115] In addition, if the processing system 10 detects a dismounting event after detecting a stop event, and if no living creature is detected to have been left behind in the vehicle even after a predetermined time has passed since the most recent dismounting event, the processing system 10 may terminate the process of detecting a living creature being left behind in the vehicle in S33.

[0116] The processing system 10 of this embodiment may include a means for detecting a stop event based on the position of the vehicle as described in the first and third embodiments.

[0117] "Effects" According to the processing system 10 of this embodiment, the same effects as those of the processing systems 10 of the first to third embodiments are realized.

[0118] Furthermore, the processing system 10 of this embodiment can detect a dismounting event using a unique method and update the reference value in response to the detection. By updating the reference value at such an appropriate timing, the CO ２ The problem of suppressing erroneous determinations in detecting whether a living organism has been left behind in a vehicle based on concentration is solved.

[0119] Fifth Embodiment The processing system 10 of this embodiment can vary the content of the warning process that is performed when it detects that a living creature has been left behind in a vehicle, depending on the situation of the vehicle at that time. This will be described in detail below.

[0120] When it is detected that a living creature has been left behind in a vehicle, the abandonment detection unit 13 executes a first warning process or a second warning process depending on the situation of the vehicle at that time. The warning process executed by the abandonment detection unit 13 when it is detected that a living creature has been left behind in a vehicle will be described using the flowchart of FIG.

[0121] 13 , when it is detected that a living creature has been left behind in a vehicle and the current situation of the vehicle satisfies a first condition (Yes in S50), the abandonment detection unit 13 executes a first warning process (S51). When it is detected that a living creature has been left behind in a vehicle and the current situation of the vehicle does not satisfy the first condition, the abandonment detection unit 13 executes a second warning process (S52).

[0122] The first condition includes at least one of the following: the temperature inside the vehicle is within a preset danger range; the vehicle doors are locked; the vehicle is located within a predetermined area; and the time is within a preset time period.

[0123] The abandoned vehicle detection unit 13 can identify the "temperature inside the vehicle" based on the measurement value of the temperature sensor mounted on the vehicle. The abandoned vehicle detection unit 13 can also identify the "lock status of the vehicle doors" based on the information handled by the in-vehicle system 20.

[0124] The abandoned vehicle detection unit 13 can also identify the "vehicle location" based on measurements from a location sensor mounted on the vehicle. The "predetermined area" may be, for example, the registered area described in the second embodiment, or an area designated by the user using other methods.

[0125] The "preset time period" may be set by the user. For example, the user can set a time period during which the vehicle is not normally used as the "preset time period." If a living creature is left behind in a vehicle during such a time period, the possibility that the creature will be left unattended will increase.

[0126] The first warning process and the second warning process differ from each other in the content of the warning process. The first warning process, which is performed when a first condition is satisfied, has a higher level of urgency. For example, the first warning process and the second warning process may differ from each other in at least one of the notification destination, notification content, and notification mode.

[0127] -Notification Destination- For example, a user may pre-register a notification destination when a first condition is met and a notification destination when the first condition is not met. Because the notification when the first condition is met is more urgent, the user may register more notification destinations when the first condition is met than when the first condition is not met. As an example, the user may register the contact information of the father and mother as notification destinations when the first condition is not met, and the contact information of the father, mother, grandparents, and relatives as notification destinations when the first condition is met.

[0128] - Notification Contents - For example, the notification content when the first condition is met may indicate the content of the first condition that has been met in addition to the fact that a living creature has been detected abandoned in the vehicle. The notification content when the first condition is met may further include the location information of the vehicle where the abandonment was detected, the date and time when the abandonment was detected, the elapsed time since the stop event was detected, the current state of the interior of the vehicle (CO ２ Concentration, temperature, etc.) may also be shown.

[0129] On the other hand, the notification content when the first condition is not satisfied may only indicate that a living creature has been detected as abandoned in a vehicle, and may also include other information such as the location information of the vehicle where the abandoned creature was detected.

[0130] - Notification Mode - The notification mode when the first condition is met is more likely to attract the user's attention than the notification mode when the first condition is not met. For example, when the first condition is met, the information displayed on the display may be highlighted by flashing or displaying it in a more noticeable color. Alternatively, when the first condition is met, a warning sound may be output. However, when the first condition is not met, notification in this mode may not be provided.

[0131] Other configurations of the processing system 10 of this embodiment are similar to those of the first to fourth embodiments.

[0132] According to the processing system 10 of this embodiment, the same effects as those of the first to fourth embodiments are achieved.

[0133] Furthermore, according to the processing system 10 of this embodiment, when a living creature is detected to have been left behind in a vehicle, a warning process can be performed according to the situation of the vehicle at that time. Specifically, in a situation with a higher degree of urgency, a warning process can be performed in a manner appropriate to that situation. By performing a warning process according to the situation of the vehicle, it is expected that serious accidents caused by living creatures being left behind in a vehicle can be prevented.

[0134] Sixth Embodiment The processing system 10 of this embodiment is configured to calculate the CO2 inside a vehicle after a stop event is detected.２ Concentration minus the reference value (CO ２ If the increase in concentration exceeds a threshold, it is determined that a living thing has been left behind in the vehicle. The processing system 10 has a means for setting this threshold for each vehicle. This will be explained in detail below.

[0135] 14 shows an example of a functional block diagram of the processing system 10 of this embodiment. As shown in the figure, the processing system 10 has a stop detection unit 11, a reference value registration unit 12, an abandonment detection unit 13, a storage unit 14, an alighting detection unit 15, a reference value update unit 16, and a threshold setting unit 17. Note that the processing system 10 does not need to have the storage unit 14. In this case, an external device configured to be able to communicate with the processing system 10 has the storage unit 14. Furthermore, the processing system 10 does not need to have the alighting detection unit 15 and the reference value update unit 16.

[0136] As in the first to fifth embodiments, the abandoned vehicle detection unit 13 detects the CO ２ If the value obtained by subtracting the reference value from the concentration is equal to or greater than the threshold value, it is determined that an organism has been left behind in a vehicle.

[0137] The threshold setting unit 17 sets a threshold based on the vehicle attribute information and occupant information related to the vehicle occupants. The threshold setting unit 17 sets a threshold for each vehicle. The storage unit 14 can store information such as that shown in Fig. 15. Fig. 15 shows information linking vehicle identification information with thresholds.

[0138] "Vehicle attribute information" includes at least one of the vehicle model and vehicle name. In this embodiment, vehicle attribute information for each vehicle is registered in advance in the processing system 10 as an initial setting for receiving services from the processing system 10. "Vehicle model" is information indicating the body type, such as sedan, minivan, or SUV. The approximate size of the vehicle can be identified based on the vehicle model and vehicle name.

[0139] The threshold setting unit 17 sets a smaller threshold value for a larger vehicle. ２ This is because the concentration is difficult to increase.

[0140] There are various ways to set such thresholds, and no particular limitations are imposed. For example, standard information that defines thresholds for each vehicle type or vehicle name in advance may be generated and registered in the processing system 10. In this standard information, the larger the vehicle, the smaller the threshold value set. The threshold setting unit 17 may then set a threshold value for each vehicle based on the standard information.

[0141] The "occupant information" includes age information of the occupant. The age information may be information indicating the age of the occupant. Alternatively, the age information may indicate an age category such as infant, child, adult, elderly, etc.

[0142] The threshold setting unit 17 acquires age information of the occupants of each vehicle. Then, the threshold setting unit 17 sets a lower threshold when an occupant of a predetermined age group is included compared to when an occupant of the predetermined age group is not included. The occupant of the predetermined age group may be a small child (e.g., under 6 years old), an elderly person (e.g., over 80 years old), etc. When an occupant of such a predetermined age group is left inside the vehicle, the CO2 inside the vehicle is lower than when an occupant of another age group is left inside the vehicle. ２ It is thought that the concentration is unlikely to increase.

[0143] The threshold setting unit 17 can acquire the age information of the occupants of each vehicle by any of the following acquisition methods 1 to 3. The age information is information that serves as a guideline for indicating the age of the occupants riding in the vehicle. The age information may be information indicating the age of the occupants who actually ride in the vehicle at that time. Alternatively, the age information may be information indicating the age of the occupants who tend to ride in each vehicle.

[0144] Acquisition Method 1 This method is used in cases where the occupants of a vehicle are generally fixed, such as a private car or a school bus. Based on user input, age information of the occupants using each vehicle is registered in advance in the processing system 10. The threshold setting unit 17 acquires the age information of the occupants that is set in this way based on the user input and registered in the processing system 10 in association with each vehicle.

[0145] Acquisition Method 2: This method can be used not only for vehicles with a fixed occupant population, such as private cars and school buses, but also for public transportation (e.g., public buses) where the occupant population varies each time. In this method, a camera mounted in a designated location on the vehicle captures an image of the occupant, and the image is analyzed to estimate the occupant's age. Age estimation using image analysis can be achieved using any technology.

[0146] For example, if the vehicle is a large vehicle such as a bus, a camera may be installed at the entrance or exit of the vehicle. The camera is installed in a position and orientation that allows it to capture images of people riding in the vehicle. The threshold setting unit 17 detects people from images generated by such a camera and estimates the ages of the detected people. The threshold setting unit 17 then registers the estimated ages as age information. If multiple people are detected, the threshold setting unit 17 registers the estimated ages of the multiple people as age information.

[0147] Acquisition Method 3: This method is used in cases where the occupants of a vehicle are different each time, such as public transportation (e.g., public buses). The threshold setting unit 17 identifies an age trend corresponding to the driving characteristics of the vehicle for which the threshold is set from information indicating the past age trends of occupants shown by at least one driving characteristic among month, day of the week, time zone, weather, and route. The identified age trend becomes the age information of the occupants of that vehicle.

[0148] Information indicating the age trends of occupants in the past for each driving characteristic is generated in advance and registered in the processing system 10. The threshold setting unit 17 executes the above-described processing based on the generated information. There are no particular limitations on the means for generating the information indicating the age trends, and any technology can be adopted.

[0149] Other configurations of the processing system 10 of this embodiment are similar to those of the first to fifth embodiments.

[0150] According to the processing system 10 of this embodiment, the same effects as those of the first to fifth embodiments are realized.

[0151] Furthermore, according to the processing system 10 of this embodiment, it is possible to set an appropriate threshold value for each vehicle to detect whether a living thing has been left behind in the vehicle. ２ The way in which the concentration increases (the rate of increase, rate of increase, range of increase, etc.) may differ. By setting an appropriate threshold for each vehicle, it is possible to accurately detect whether a living thing has been left behind in a vehicle.

[0152] <Modifications> Here, modifications applicable to the first to fifth embodiments will be described. These modifications also achieve the same effects as the first to fifth embodiments.
