Note that the embodiment described below shows an example of how the present invention can be implemented, and the present invention is not limited to the specific configuration described below. When implementing the present invention, a specific configuration according to the embodiment may be appropriately adopted.

In addition, the terminology used in the following explanation, for example, the horizontal direction does not have to be strictly horizontal, but may be substantially horizontal. The same applies to the vertical downward direction, vertical, parallel, normal, etc.

[1. How the idea came about]
First, the background to the conception of the present invention will be described.
People, including infants and kindergarteners, can be left behind in vehicles. In addition, in an aging society, there are more opportunities to transport elderly people to day care services and rehabilitation facilities, but there are concerns that similar situations may occur with physically disabled elderly people. In addition, people may leave their luggage behind in buses, trains, and other vehicles, and it may take a lot of effort to retrieve it. Therefore, there is a need to develop a system that can prevent people or objects from being left behind unintentionally in vehicles.

In relation to this, in vehicles such as microbuses, the driver may get off the vehicle, lock the doors, and leave the vehicle without realizing that a passenger remains inside. For example, if the vehicle is a shuttle bus for a kindergarten or nursery school and the passenger is a small child, it may be difficult for the small child left inside the vehicle to unlock the door and get out by themselves. Occupants who are left behind in such vehicles may be trapped in adverse environments such as high and low temperatures, exposing them to physical danger.

As a monitoring system for preventing such abandonment in vehicles, an alarm system has been proposed that starts an alarm inside the vehicle when the engine is turned off, and continues the alarm until a confirmation button attached to the rear of the vehicle is pressed. With this alarm system, a person who should check that no one has been left inside the vehicle (typically the driver or a childcare worker riding with the vehicle, hereafter referred to as the "checker") must move to the rear of the vehicle to stop the alarm after the engine is turned off, and at that time can check whether any occupants (children) remain in the vehicle. The confirmation button is installed at the rear of the vehicle in a position that cannot be easily pressed by children.

There is also a known abandoned vehicle monitoring system to prevent abandoned passengers from being left inside a vehicle, in which an abandoned occupant (child) presses an alarm button inside the vehicle to sound an alarm (horn, light up lamps) outside the vehicle.

In the following explanation, an example will be given in which the abandoned vehicle monitoring system of the present invention is applied to a bus that transports children to and from a kindergarten (hereinafter sometimes simply referred to as "kindergarten"). In the following explanation, "inside the vehicle" will sometimes be called "inside the car", but in both cases, it is used to mean the interior of the vehicle where people may be present (i.e., the inside of the car).

In the following description, the vehicle will be described as an internal combustion engine vehicle that has an engine as its driving source, but the vehicle is not limited to this and may be a hybrid vehicle that has an engine and a traction motor as its driving source, or an electric vehicle that has a traction motor as its driving source. In addition, the vehicle will be described as a small bus such as a microbus, but the vehicle is not limited to this and may be a large bus.

2. Configuration of the abandoned vehicle monitoring system
FIG. 1 is a block diagram showing the configuration of an abandoned vehicle monitoring system according to an embodiment of the present invention. The abandoned vehicle monitoring system 100 is a system for monitoring people in a vehicle, and has a function of monitoring people and outputting information according to the monitoring result. The abandoned vehicle monitoring system 100 includes a main unit 11, a plurality of sensors 12a to 12d, a buzzer 13, a dismount confirmation switch 14, an emergency call switch 15, an answerback unit 16, a first drive recorder 17, a second drive recorder 18, a personal computer 19, a transceiver 20, a monitoring terminal 21, and a personal computer 22. The plurality of sensors 12a to 12b, the buzzer 13, the dismount confirmation switch 14, the emergency call switch 15, the answerback unit 16, the first drive recorder 17, and the second drive recorder 18 are connected to the main unit 11 to form an in-vehicle system. The main unit 11 is also configured to be able to connect to a personal computer 19 as necessary. A mobile terminal such as a smartphone or a tablet computer, or other terminal device may be used instead of the personal computer 19. At least the main unit 11, the multiple sensors 12a to 12d, the buzzer 13, the exit confirmation switch 14, the emergency call switch 15, the answerback unit 16, the first drive recorder 17, and the second drive recorder 18 are mounted on the vehicle side.

Furthermore, the main unit 11 is connected to the vehicle's ACC (accessory power) input and horn output. The ACC input is a power line to which power from the ACC is input. The ACC is an example of a power source on the vehicle side. The horn output is a signal line to which an instruction to make the horn emit a sound is output. The horn is an example of an alarm unit that issues an alarm. A constant power source (+B) is connected to the main unit 11 as a power source for supplying power to the main unit 11 even after the engine or ACC is turned off. The main unit 11 is also connected to a power line (GND) that supplies a ground potential. Note that the abandoned vehicle monitoring system 100 may have, for example, a built-in battery or be connected to an external battery, and may receive power from the battery so that the abandoned vehicle monitoring system 100 can operate even when the ACC is off.

The main unit 11 may further have a terminal for connecting an OBDII adapter that can be connected to the OBDII ("II" is the Roman numeral for "2") connector of the vehicle V. The OBDII connector is also called a fault diagnosis connector, and is a terminal that is connected to the vehicle's ECU (Engine Control Unit) and outputs various vehicle information at predetermined intervals (e.g., every 0.5 seconds). By connecting this terminal to the OBDII connector using an OBDII adapter, the main unit 11 can receive power for operating the abandoned vehicle monitoring system and acquire vehicle information.

Vehicle information is information related to the state of the vehicle. Examples of vehicle information include vehicle speed (vehicle speed), engine RPM, engine load factor, throttle degree, ignition timing, percentage of remaining fuel, intake manifold pressure, intake air volume (MAF), injection open time, engine coolant temperature (coolant temperature), temperature of air drawn into the engine (intake temperature), air temperature outside the vehicle (outside air temperature), amount of remaining fuel in the fuel tank (remaining fuel amount), fuel flow rate, instantaneous fuel consumption, accelerator opening, turn signal information (operation of left and right turn signals (ON/OFF)), brake opening, steering wheel rotation angle, gear position, and door open/close status.

The main unit 11 controls the entire system mounted on the vehicle side of the abandoned vehicle monitoring system 100. The main unit 11 is an example of a control unit that controls each part mounted on the vehicle side of the abandoned vehicle monitoring system 100. The main unit 11 is a computer including, for example, a processor and a memory. The processor has, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), an ASIC (Application-Specific Integrated Circuit), and an FPGA (Field Programmable Gate Array). The memory may include a main storage device having, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory). The processor temporarily stores a program read from the ROM of the memory in the RAM. The RAM of the memory provides a working area for the processor. The processor performs various controls by temporarily storing data generated during the execution of the program in the RAM while performing arithmetic processing. The memory may further include a hardware disk, SSD, or other auxiliary storage device for permanently storing data. In addition to this, the main unit 11 may include a timekeeping unit (e.g., a real-time clock) that measures time, and other elements necessary to realize each function described below.

Sensors 12a-12d are configured by combining a Doppler sensor (which may be called a microwave sensor) and an IR (which may be called an infrared) sensor. In this embodiment, four sensors (sensors 12a-12d) are attached to the vehicle, so that the entire interior of the vehicle or a spatial area appropriate for fulfilling the functions of the abandoned vehicle monitoring system 100 is the subject of detection by the sensors. However, three or less or five or more sensors may be attached to the vehicle. Sensors 12a-12d are examples of sensors that detect the situation inside the vehicle.

The buzzer 13 outputs a buzzer sound in response to an instruction from the main unit 11. The alighting confirmation switch 14 is a push button switch that detects a push operation. The alighting confirmation switch 14 is a switch for alighting confirmation that is operated after confirming that the occupants in the vehicle have alighted after the ACC is turned off. Therefore, the alighting confirmation switch 14 should be installed taking into consideration the place that the occupant will always pass through when confirming the alighting confirmation. For example, assuming that the person making the confirmation is the driver, the alighting confirmation switch 14 should be installed at the rear side of the vehicle, which is further back than the spatial area (boarding area) in which the seats are located, as seen from the driver's seat of the vehicle. Such a "alighting confirmation switch" may be referred to as a "rear switch" below. By operating the alighting confirmation switch 14, an operation signal indicating that the operation has been performed is supplied to the main unit 11. Furthermore, the main unit 11 is notified of the operation to the transceiver 20 via the answerback unit 16. Here, the alighting confirmation switch 14 comprises a physical switch, but it may also be realized by an operation unit (first operation unit) that detects contact operations using a touch panel or non-contact operations using a proximity sensor.

The transceiver 20 is a computer device equipped with a display unit consisting of a liquid crystal panel or the like. The transceiver 20 may be a remote control used by the driver of the vehicle, but if it is a device used by someone other than the driver, such as a nursery school or kindergarten staff member within the facility, it will have a function to check whether a third party other than the driver has disembarked. In the following, unless otherwise specified, the transceiver 20 will be assumed to be a tabletop transceiver placed within the kindergarten (within the kindergarten facility) that operates and manages the vehicle.

In addition, if the exit confirmation switch is not operated within a certain period of time after ACC is turned off, the main unit 11 notifies the transceiver 20 of this fact via the answerback unit 16 and sounds the vehicle's horn. The transceiver 20 receives a notification or report from the vehicle and reports information based on that notification or report.

The emergency call switch 15 is a push button switch that detects a push operation when the abandoned vehicle monitoring system 100 is in monitoring mode. The emergency call switch 15 is a switch for making an emergency call that is operated by an occupant when the occupant is left behind. By operating the emergency call switch 15, the main unit 11 reports an emergency to the transceiver 20 via the answerback unit 16 and sounds the vehicle's horn. Here, the emergency call switch 15 comprises a physical switch, but may also be realized by an operation unit (second operation unit) that detects a contact operation using a touch panel or a non-contact operation using a proximity sensor.

In this way, when the button attached to the vehicle is pressed, a siren is activated, and a loud sound is emitted from a speaker such as a security product, thereby notifying the outside that a person has been left behind in the vehicle. The emergency call switch 15 is preferably designed to have a reaction force that even a small child can press. In addition, to prevent children from tampering with the vehicle while it is running, the operation of the emergency call switch 15 may be linked to the ACC input. For example, the emergency call switch 15 may be designed to operate only when the accessory power is off. For example, the main unit 11 may activate the siren in response to the operation of the emergency call switch 15 when the accessory power is off, but may not activate the siren in response to the operation of the emergency call switch 15 when the accessory power is on. Such an emergency call switch 15 may be called an anti-personnel-abandonment button, etc.

The monitoring mode is a predetermined operation mode for monitoring the inside of the vehicle. The main unit 11 starts the monitoring mode, for example, when the ACC power is turned off or when the vehicle engine is turned off. The main unit 11 ends the monitoring mode, for example, when the ACC power is turned on or when the vehicle engine starts to operate. The main unit 11 may end the monitoring mode when it is determined that no person is present in the vehicle. The answerback unit 16 is a device having an answerback function. The answerback unit is a hardware element that can also be applied to a security system (car security system) for preventing vehicle theft or vandalism. In this way, if the car security system is diverted to another purpose such as an abandoned vehicle monitoring system, it is possible to simplify the manufacturing process and reduce manufacturing costs, as well as reduce the manufacturing of new parts and devices by repurposing parts and devices, leading to the provision of environmentally friendly technology and contributing to the SDGs.

The answerback unit 16 performs wireless communication with the transceiver 20, for example, using 429 MHz band radio. The 429 MHz band radio is, for example, a special low-power radio. Special low-power radio is a type of wireless communication that is sometimes used in car security systems. The wireless communication between the main unit 11 and the transceiver 20 is not limited to a method via the answerback unit 16, but may be performed using other wireless communication units (for example, a wireless communication module having a communication line and an antenna). The communication method is also not limited to special low-power radio, but may use other communication methods such as Wi-Fi (registered trademark) and Bluetooth (registered trademark). For example, it is preferable that a communication environment is established in which the answerback unit 16 and the transceiver 20 can communicate, taking into account the location and distance of the system installed in the vehicle and the transceiver 20, and the environment of these.

The first drive recorder 17 records the image by photographing the inside of the vehicle according to the control of the main unit 11. The first drive recorder 17 is an example of a first imaging device mounted on a vehicle to capture the image. The first drive recorder 17 has a function of performing wireless communication with the monitoring terminal 21, for example, using WiFi (registered trademark) or Bluetooth (registered trademark). The second drive recorder 18 records the image by photographing the inside of the vehicle according to the input from the sensors 12a to 12d. The second drive recorder 18 is an example of a second imaging device mounted on a vehicle to capture the image. That is, the second drive recorder 18 starts a recording operation triggered by the occurrence of an event in which the sensors 12a to 12d detect an occupant. This recording operation may be a recording operation that is understood as a so-called event recording. The second drive recorder 18 further transmits the recorded image to the monitoring terminal 21 using wireless communication. The second drive recorder 18 may transmit the recorded video in parallel with the recording operation, and it is particularly preferable to transmit the recorded video so that the real-time video can be confirmed by an external device. When the first drive recorder 17 and the second drive recorder 18 transmit the video, they may transmit the video without going through the main unit 11, or the main unit 11 may receive the video from the first drive recorder 17 and the second drive recorder 18 and transmit the video. In this embodiment, the first drive recorder 17 and the second drive recorder 18 are used, but as long as they have the function of capturing and outputting the captured video, a capturing device (first capturing device, second capturing device) that is not recognized as a drive recorder may be used. The capturing device may be equipped with, for example, a CCD or CMOS as an image sensor. The capturing device may output the captured video to the main unit 11 by wired or wireless communication.

The personal computer 19 is a computer device that connects to the main unit 11 to perform various settings and obtain history information (e.g., about 20 items) from the main unit 11.

The monitoring terminal 21 is a computer device for monitoring the state of the vehicle from a location away from the vehicle. If the monitoring terminal 21 is a device used by a person other than the driver of the vehicle, the monitoring function can be performed by a third party other than the driver. It is convenient to use a mobile terminal device such as a smartphone or tablet computer as the monitoring terminal 21, but a stationary terminal device or other information processing device may also be used. Like the transceiver 20, the monitoring terminal 21 is used within the kindergarten (e.g., within the kindergarten facilities) that operates and manages the vehicle. The personal computer 22 is a computer device that is connected to the transceiver 20 as necessary to send emails in the event of an alarm and to manage documents.

Although not shown in the figures, each computer device such as the personal computer 19, the transceiver 20, the monitoring terminal 21, and the personal computer 22 has a processor (e.g., a CPU) and a memory (e.g., a RAM), and realizes various functions by reading and executing programs into the memory. In addition, each device such as the personal computer 19, the transceiver 20, the monitoring terminal 21, and the personal computer 22 may have the necessary component devices to realize each function described below, such as an operation unit, a display unit, and a communication unit.

[3. Vehicle configuration example]
Fig. 2A is a side view of a vehicle according to an embodiment of the present invention, and Fig. 2B is a plan view of the interior of the vehicle according to an embodiment of the present invention. In the examples of Fig. 2A and Fig. 2B, the vehicle 50 is a small bus called a microbus that can accommodate about 10 to several dozen passengers. A driver's seat 51 is provided at the front of the vehicle 50, a boarding/alighting door 52 is provided at the center slightly toward the front on the side opposite the driver's seat 51, and multiple seats 54 for passengers are provided on both sides of a central aisle 53.

As shown in Figures 2A and 2B, a main unit 11 and an answerback unit 16 are provided at the front of the vehicle 50, an emergency call switch 15 is provided at the boarding/alighting entrance 52, and an alighting confirmation switch 14 is provided at the rear of the vehicle 50. Four sensors 12a-12d are installed at intervals on the ceiling of the vehicle 50 so as to detect passengers in multiple seats 54. The number of sensors 12a-12d may be more or less than four depending on the size of the vehicle (the number of seats).

4. Operational Example of the Abandonment Monitoring System 100
The abandoned vehicle monitoring system 100 operates as follows. First, the operation from the start of monitoring to the end of monitoring (in other words, when in monitoring mode) is as follows. When the ACC is turned off, the main unit 11 notifies the transceiver 20 of that effect via the answerback unit 16. At this time, the main unit 11 may also sound the buzzer 13, but since there is a high possibility that an occupant is still in the vehicle, it is preferable for the occupant not to sound the buzzer. Then, if the exit confirmation switch 14 is not pressed within a specified time after the ACC is turned off, the main unit 11 notifies the transceiver 20 of that effect via the answerback unit 16, sounds the buzzer 13, and sounds the horn. It is preferable that the specified time at this time be configured to be changeable by settings. Sounding the buzzer 13 and the horn are examples of notifying or warning.

In addition, if the exit confirmation switch 14 is operated within the specified time, the main unit 11 notifies the transceiver 20 of the operation and sounds the buzzer 13. The exit confirmation switch 14 is set to secure a delay time during which it does not accept any operation immediately after the ACC is turned off (the accepted operation is invalidated). In other words, the exit confirmation switch 14 needs to be operated after the first specified time has elapsed after the ACC is turned off and before the second specified time has elapsed. In this way, even if the exit confirmation switch 14 is pressed by an occupant such as a small child, or the driver presses the exit confirmation switch 14 without thoroughly checking the interior of the vehicle, it is preferable that the operation is not valid, but that the person who checked the interior of the vehicle (e.g., the driver) moves around the vehicle to check the interior and then presses the exit confirmation switch 14, which is treated as a valid operation. It is preferable that the first and second specified times are also configured to be changeable by setting. For example, the first and second specified times are considered to be different depending on the number of people in the vehicle or the number of seats.

During the period from the first specified time to the second specified time, while waiting for the operation of the alighting confirmation switch 14, the main unit 11 sounds the buzzer 13 to notify the person making the confirmation that the alighting confirmation switch 14 should be operated. The transceiver 20 may also have a fail-safe function that counts a specified time after receiving a notification that the ACC has been turned off, and issues an alarm (buzzer sound, display, etc.) in the transceiver 20 if it does not receive a notification that the alighting confirmation switch 14 has been operated.

After ACC is turned off, the main unit 11 activates the sensors 12a to 12d and starts monitoring after a specified time has elapsed, regardless of whether the disembarkation confirmation switch 14 is operated. It is preferable that the specified time until monitoring starts and the specified time until monitoring ends can be changed by settings. The main unit 11 cancels monitoring the next time ACC is turned on, and the main unit 11 notifies the transceiver 20 of this via the answerback unit 16 and sounds the buzzer 13.

The operation of issuing an alarm or warning is as follows. When any of the sensors 12a to 12d detects an occupant, the main unit 11 notifies the transceiver 20 of an alarm via the answerback unit 16, activates the buzzer 13, and sounds the horn. In this case, the main unit 11 keeps the buzzer 13 and horn sounding until a specified operation is performed. The specified operation is preferably a predetermined operation performed after checking the interior of the vehicle 50, such as pressing the exit confirmation switch 14. Also, when the emergency call switch 15 is operated, the main unit 11 notifies the transceiver 20 of an alarm via the answerback unit 16, activates the buzzer 13, and sounds the horn.

When a button is pressed to stop the alarm, the transceiver 20 notifies the main unit 11 that this button operation has been performed. The main unit 11 receives notification of this button operation via the answerback unit 16 and temporarily stops the buzzer 13 from sounding. If the transceiver 20 does not cancel the alarm within a specified time (e.g., 5 minutes), the main unit 11 will sound the buzzer 13 again.

If the vehicle 50's horn is sounding, the horn can be stopped by turning on the ACC of the vehicle 50 or by operating the disembarkation confirmation switch 14. When the horn is stopped, the main unit 11 notifies the transceiver 20 of this via the answerback unit 16.

As described above, the transceiver 20 has the functions of receiving and displaying notifications of ACC on and off, receiving and displaying notifications of operation of the alighting confirmation switch 14 and displaying an alarm if the alighting confirmation switch 14 is not operated within a preset period of time, displaying an alarm or warning based on detections by the sensors 12a to 12d, receiving and displaying notifications of operation of the emergency call switch 15, checking history (e.g., 20 items) by button operation, and making various settings (e.g., settings can be changed by entering a PIN number).

A personal computer 22 is also connected to the transceiver 20. The personal computer 22 realizes a function of managing and recording documents. The document records the date and time when the ACC was turned on, the date and time when the ACC was turned off, the date and time when the disembarkation confirmation switch 14 was operated, the date and time when the sensors 12a to 12d detected an occupant and issued an alarm or warning, the date and time when the emergency call switch 15 was operated, and the like. In addition, by connecting the personal computer 22 to the transceiver 20, a function is realized in which the personal computer 22 sends, for example, text data to a registered email address when an alarm is issued.

As described above, in the abandoned vehicle monitoring system 100 of this embodiment, an emergency call switch 15 is provided in the vehicle, and when the emergency call switch 15 is operated during monitoring, the main unit 11 sounds the horn to notify the outside. At this time, the main unit 11 may also turn on the hazard lights and headlights. Furthermore, in an emergency, the main unit 11 transmits (sends) the images recorded by the first drive recorder 17 and the second drive recorder 18 to the outside, and wirelessly notifies the external transceiver 20 and monitoring terminal 21 that an emergency situation (a vehicle has been abandoned) has occurred. In this case, the transceiver 20 and monitoring terminal 21 may display the images captured by the first drive recorder 17 and the second drive recorder 18.

[5. Another configuration example or operation example of the abandoned vehicle monitoring system 100: Part 1]
Other configuration examples or operation examples of the abandoned object monitoring system 100 will be described below. Two or more of the following configuration examples or operation examples can be combined as appropriate. In addition, the configuration examples or operation examples can be combined as appropriate with other configuration examples or operation examples in this specification.

The sensors 12a to 12d may be attached to the ceiling of the vehicle 50 using a bracket that prevents the children from removing it. Assuming that the children cannot reach the ceiling of the vehicle 50, the sensors 12a to 12d may be attached to the ceiling in some way. The sensors 12a to 12d may also be attached to a location other than the ceiling that is out of reach of the children.

The exit confirmation switch 14 is a switch that is operated when the person who checks has confirmed that nothing has been left behind, and is not a switch that should be operated by the child, so it may be a valet switch that is ineffective even if the child presses it. In this case, the valet switch may be operated by inputting a two-digit number using two buttons (stopping the buzzer 13). For example, the valet switch may be required to be operated to a degree that does not cause stress to the person who checks, such as pressing the left button twice and the right button three times. The valet switch is an operation unit that is sometimes used in car security systems for authentication to confirm that the user is a legitimate user of the vehicle. If this authentication is successful, the security monitoring state is released. The valet switch is preferably located in a place that is difficult for the legitimate user of the vehicle to understand, for example, in a position that is not visible or difficult to see from outside the vehicle. Therefore, the exit confirmation switch 14, which is a valet switch, is preferably located in a position that is not visible or difficult to see from outside the vehicle, such as below the rearmost part.

Now, if a loud sound is sounded within 10 seconds after the engine is turned off, it is unlikely that all the children will get off within 10 seconds after the engine is turned off, and a sound of 85 dB or more will start sounding while the children are still in the car, and the driver, acting as the checker, will rush to the exit confirmation switch 14. In this case, the loud sound will be bad for the children's mental state, and the children will head to the exit gate while the driver heads in the opposite direction, which may lead to a collision between the driver and the inside of the car. A method that does not panic is to have the children get off with the engine running, but this may also be undesirable. Therefore, the main unit 11 may play a soft sound, melody, or voice (hereinafter collectively referred to as "soft sound, etc.") immediately after the vehicle engine is turned off, to remind the driver not to forget to press the exit confirmation switch 14 (for example, the rear valet switch). In this case, it is preferable not to set a time limit before the sound is sounded. This is because soft sounds are not painful for the driver or the children to hear, and are, for example, comfortable. When the driver thinks that all the children have disembarked, he or she can slowly go and operate the disembarkation confirmation switch 14. This is because the purpose is to patrol the inside of the vehicle. Also, the main unit 11 does not go into monitoring mode while waiting for the disembarkation confirmation switch 14 to be operated. When the driver presses the disembarkation confirmation switch 14, the main unit 11 stops the soft sounds. The driver looks around the inside of the vehicle, disembarks, and closes the door. The main unit 11 may go into monitoring mode only after detecting that the door is closed. If the main unit 11 detects that the door is closed without operating the disembarkation confirmation switch 14, it may sound a siren (e.g., a buzzer 13 or a horn). A sensor for detecting door closure, which will be described later, may be used to detect door closure.

Alternatively, in the above embodiment, the main unit 11 sounds the buzzer 13 when the ACC is turned off. Alternatively, the buzzer 13 may be sounded when the engine is turned off to prompt the person checking to see if any children have been left behind and to operate the alighting confirmation switch 14. In this case, there is no need to set a time limit for operating the alighting confirmation switch 14. This specification allows the person checking to take sufficient time to check that all children have alighted. Furthermore, the main unit 11 does not enter monitoring mode while waiting for the alighting confirmation switch 14 to be operated. In other words, the main unit 11 disables the operation of the emergency call switch 15. This makes it possible to prevent an alarm or warning from being issued even if a child operates the emergency call switch 15 when alighting.

A sensor for detecting door closure may be provided at the boarding/alighting entrance 52. In this case, the person checking can confirm that nothing has been left behind in the vehicle and then operate the alighting confirmation switch 14, which causes the main unit 11 to stop sounding the buzzer 13 and, upon closing the door, detect this door closure and start monitoring mode. If the main unit 11 detects door closure without operating the alighting confirmation switch 14, it may sound a single warning siren.

The main unit 11 may also notify the transceiver 20 of events inside the vehicle, such as turning off the engine, operating the exit confirmation switch 14, or detecting door closure, at any time, and keep a history or document the history.

In this way, the monitoring mode may be activated when both the child and the person checking exit the vehicle and close the door. In this case, for example, the person may later realize that they have left something inside the vehicle and open the door again. In this case, the sensor will detect the door being open. Even if sensors 12a to 12d detect an occupant thereafter, no alarm or warning will be issued because the door is open. Therefore, rather than immediately issuing an alarm or warning when sensors 12a to 12d detect an occupant, the main unit 11 may issue an alarm or warning after confirming that the engine is off and the door is closed (for example, with a delay of about one second).

When the vehicle 50 departs from the departure point, it is also possible that the engine is off, the doors are closed, and children are in the vehicle. That is, the engine is started after all the children have boarded and the doors are closed. For example, the vehicle 50 is about to depart. In this state, it is necessary to prevent an alarm from being issued. In this case, the monitoring mode is released when the door is opened, and then when the driver gets in and closes the door, the engine is still off at this time, so the conditions of engine off and door closing are met. However, since the order of operation of the reset button on the driver's seat 51, operation of the exit confirmation switch 14, and door closing is not the order, the main unit 11 does not release the monitoring mode. That is, the order of operation of the exit confirmation switch 14 is added to the condition of engine off and door closing, so that the monitoring mode is entered. By doing this, the monitoring mode may be prevented from being activated in the above-mentioned situation.

It is possible that a child may operate the alighting confirmation switch 14 while all the children are alighting. To prevent this, a reset button may be installed in the driver's seat 51, and once the driver, who is responsible for checking, has confirmed that all the children have alighted from the driver's seat 51, he or she may operate the reset button and then move around the vehicle 50 to operate the alighting confirmation switch 14. When the reset button is pressed, the main unit 11 may disable the operation of the alighting confirmation switch 14, even if the alighting confirmation switch 14 has been operated. In this way, inconveniences caused by children operating the alighting confirmation switch 14 can be reduced.

The volume of the buzzer 13 that prompts the person checking the rear seat visually may be changeable by settings. The main unit 11 may be configured to emit a sound from the buzzer 13 at a volume that corresponds to the setting.

Alternatively, the main unit 11 may be configured with a speaker that can adjust the volume to encourage people in the rear seats to visually check after the engine is turned off. If the volume exceeds a certain volume as specified by the standard, a sound source that generates a sound above the certain volume, such as a siren, may be used to emit a sound. The certain volume may be, for example, 85 dB, but is not limited to this.

[6. Another configuration example or operation example of the abandoned vehicle monitoring system 100: Part 2]
The following configuration or operation example can be appropriately combined with other configuration or operation examples in this specification.
In a monitoring system for preventing children from being left behind in vehicles, it is most important to be able to detect when a child has been left behind on a bus. However, in reality, the vehicle departs from a parking lot in an empty state, passes through a pick-up and drop-off point, takes children and teachers to a nursery school or kindergarten, and returns the vehicle 50 to the parking lot. It is also assumed that the engine will be stopped during the pick-up and drop-off process, and that teachers and drivers will leave children on the bus and get off. In addition, after dropping off the children, the bus may be returned to the parking lot, the vehicle may be inspected at a dealer, the bus may go on a field trip, or the children may touch the rear button, and various other situations may be considered. The problem is what operation or action should be performed at each time.

Figures 3A and 3B are tables showing examples of actions in various situations. Figure 3A shows actions for going, i.e., taking children to the nursery, and Figure 3B shows actions for returning, i.e., taking children from the nursery to the pick-up and drop-off location.

A61: Prompts patrol A62: Resets rear button operation by child A63: Stops melody A64: Prompts patrol A65: Notifies (alerts, notifies) failure to switch to monitoring mode

In the above embodiment, the vehicle 50 is provided with two drive recorders, the first drive recorder 17 and the second drive recorder 18, but only one of them may be used. Recording by these drive records may be performed only when the sensors 12a to 12d react when there is absolutely no one in the vehicle (i.e., when the vehicle is in monitoring mode). This makes it possible to avoid unnecessary recording when it is not necessary. In this way, the main unit 11 is configured so that the first drive recorder 17 and the second drive recorder 18 can be connected and recording inside the bus is also possible. However, assuming that there are cases where it is not acceptable to record the children, it is best to record only when there is absolutely no one in the vehicle. When no one is supposed to be in the vehicle, the sensors 12a to 12d (here, the microwave sensor + IR sensor) do not react (i.e., the presence of a person is not detected), so the main unit 11 may cause the first drive recorder 17 and the second drive recorder 18 to record when the sensors 12a to 12d react (i.e., the presence of a person is detected). Furthermore, when the sensors 12a to 12d do not react (i.e., the presence of a person is not detected), the main unit 11 may not cause the first drive recorder 17 and the second drive recorder 18 to record, in other words, stop recording. Other conditions may be used as conditions indicating that no one is supposed to be in the vehicle.

In addition, the report creation is realized by the main unit 11 sending operational events such as engine on, engine off, button operation, door opening/closing, and operational errors, as well as operational events such as door opening/closing, sensor detection, and alarm generation to the transceiver 20, which then sends the history to the personal computer 22. The report (history) created in this way can be used for the education of drivers and teachers.

[7. Other configuration or operation example of the abandoned vehicle monitoring system 100: Part 3]
The following configuration or operation examples can be appropriately combined with other configuration or operation examples in this specification.
As described above, the abandoned vehicle monitoring system 100 may be configured to activate the monitoring mode when the door is closed when the reset operation, rear button operation, and door closing are detected in this order. However, if this is done, the alarm mode will also be activated when the driver closes the door inside the bus. In response to this, a GPS may be used to distinguish between places where an alarm must be issued, such as kindergartens and parking lots, and places where an alarm should not be issued, such as pick-up and drop-off stations. Therefore, the abandoned vehicle monitoring system 100 may have a location information acquisition unit as a function of acquiring location information using GPS. The vehicle 50 may be equipped with a GPS receiver. In the abandoned vehicle monitoring system 100, places such as kindergartens, parking lots, and pick-up and drop-off stations are registered as areas (so-called my areas) that are permitted to issue an alarm based on location information. The abandoned vehicle monitoring system 100 may issue an alarm (an example of an alarm) only in places registered as an alarm area, such as kindergartens, and may only report to the transceiver 20 without issuing an alarm in places not registered or places where a GPS signal cannot be received.

In this way, locations where an emergency alert should be issued can be registered, and the alert can be issued only when the vehicle is in that location. Alternatively, locations where an emergency alert should not be issued can be registered, and an alert will not be issued when the vehicle 50 is in that location. This makes it possible to ensure safety by preventing vehicles from being left behind, while also providing convenience by allowing cancellations at specific locations (gas stations, vehicle inspection locations, etc.).

In this specification, the description of GPS may be replaced with GNSS (Global Navigation Satellite System). Moreover, the function of performing positioning using such GPS or GNSS and acquiring position information indicating the determined position is an example of a position information acquisition unit. The position information acquisition unit acquires position information indicating the position of the vehicle (more specifically, the current position). The main unit 11 may acquire the position information from this position information acquisition unit. The position of the vehicle can be regarded as the position of the person (passenger) riding in the vehicle and the position of each device mounted on the vehicle. The location information acquisition unit acquires location information (latitude information and longitude information) based on a signal from GPS (Global Positioning System), which is one of the GNSSs, for example, but the location information acquisition unit may also use Michibiki as a Quasi-Zenith Satellite System (QZSS). The location information acquisition unit may also acquire location information by a method of identifying an access point of a connected wireless LAN, a method of base station positioning, or the like.
In this way, location registration can be used to provide notifications (e.g., alarms) when appropriate.

[8. Other configuration or operation example of the abandoned vehicle monitoring system 100: Part 4]
The following configuration or operation examples can be appropriately combined with other configuration or operation examples in this specification.
The CAN invader countermeasure device has an area detection function. The area detection may be used to control the monitoring mode. In this case, it is assumed that the driver has a transceiver (hereinafter also referred to as a "remote control") 20. The remote control may be a key (e.g., a smart key) for the driver to lock or unlock the vehicle 50, but it may be a separate remote control that is carried along with the key. For example, such a remote control may be a remote control developed for a car security system, and may have a function of receiving the vehicle's locked or unlocked state, or the state of the vehicle 50, such as the state detected by the sensors 12a to 12d, from the main unit 11 and notifying the driver. The communication between the main unit 11 and the remote control 20 is performed, for example, by a special low-power radio, but other communication methods such as Wi-Fi (registered trademark) and Bluetooth (registered trademark) may also be used.

Area detection is a function to detect whether the remote control 20 is present within a predetermined area (hereinafter sometimes referred to as a "detection area") based on the position of the main unit 11, in other words, the vehicle 50 on which the main unit 11 is mounted. "Whether the remote control 20 is present" may be read as "whether a person holding the remote control 20 is present." The person holding the remote control 20 is a confirmer who is the driver here. Detecting whether the remote control 20 is present essentially means detecting whether a person holding the remote control 20, in this example, the driver, is present. An example of area detection will be described. To explain a first method of area detection, the main unit 11 transmits a first wireless signal of a predetermined strength to the remote control 20. The first wireless signal may include, for example, information requesting notification of the reception strength of the first wireless signal. When the remote control 20 receives the first wireless signal, it calculates the reception strength of this first wireless signal. The reception strength may be a received signal strength indicator (RSSI), but other values that are indicative of the reception strength may also be used. The remote control 20 transmits a second wireless signal including information on the calculated reception strength of the first wireless signal to the vehicle-mounted system, here the main unit 11. The main unit 11 compares the reception strength of the first wireless signal determined based on the received second reception strength with a predetermined threshold, and if the reception strength of the first wireless signal is equal to or greater than the threshold, it determines that the remote control 20 is present within the predetermined detection area, and if it is less than the threshold, it determines that the remote control 20 is not present within the predetermined detection area. The threshold may be set in advance, for example, during initial setup before the abandoned vehicle monitoring system 100 begins to be used.

The method of area detection is not limited to this. To explain the second method of area detection, the remote control 20 transmits a third wireless signal of a predetermined strength, and the main unit 11 compares this third wireless signal with a predetermined threshold value. If the reception strength of the third wireless signal is equal to or greater than the threshold value, it may determine that the remote control 20 is present within the predetermined detection area, and if it is less than the threshold value, it may determine that the remote control 20 is not present within the predetermined detection area. A third method may be a combination of the first and second methods, and the main unit 11 may determine that the remote control 20 is present within the predetermined detection area if one or both of the reception strength of the first wireless signal and the reception strength of the third wireless signal are equal to or greater than the threshold value, and otherwise determine that the remote control 20 is not present within the predetermined detection area. In addition, the remote control 20 may be configured to compare the reception strength with a threshold value and transmit (notify) the result of the comparison, for example, whether or not it is within the predetermined detection area, to the main unit 11. It is particularly preferable that the first wireless signal and the third wireless signal are transmitted without an explicit instruction from the user, for example, by transmitting them at a predetermined cycle.

The range of the area detection (in other words, the range of the detection area) can be changed by setting a threshold value. The smaller the threshold value, the more the detection area will be limited to the vicinity of the vehicle 50, and the larger the threshold value, the more the detection area will include positions farther from the vehicle 50. By setting the threshold value, for example, the main unit 11 is configured to set the area detection range in 100 stages and to use the threshold value according to the set stage. For example, a case is assumed in which the area range is set to about 100 m (for example, a radius of 100 m). If the main unit 11 determines based on the area detection that the remote control 20 is within the detection area, it does not start the monitoring mode. However, the main unit 11 operates the sensors 12a to 12d, and notifies the remote control 20 when the sensors 12a to 12d detect an occupant. When the remote control 20 receives this notification, it is preferable for it to notify the driver by sounding a sound or displaying on the display unit. If the main unit 11 determines that the remote control 20 is outside the detection area, it starts the monitoring mode.

The main unit 11 and the remote control 20 operate as follows, for example. Here, the area detection range is 100 m. If the driver is within 100 m and goes to retrieve something he left behind, the main unit 11 will not activate the monitoring mode no matter what he does. When the driver is within 100 m to pick up a child on the bus, the main unit 11 will not activate the monitoring mode. Even if the main unit 11 enters monitoring mode in which the sensors 12a to 12d detect an occupant, it will not sound a siren, but will notify the remote control 20. The remote control 20 will notify the driver by sounding a sound or other means upon receiving this notification. After dropping off the child, the driver goes to the parking lot, stops the vehicle 50, and when the remote control 20 is outside the 100 m range of the vehicle 50, the main unit 11 will activate the monitoring mode. When the parking lot for the vehicle 50 is within 100 m from the driver, the main unit 11 will not activate the monitoring mode, but will notify the remote control 20 if the sensors 12a to 12d detect an occupant. The remote control 20 receives this notification and notifies the driver by sounding a sound, etc.

If the driver forgets the remote control 20, it is undesirable to have an easy way to release the remote control 20 even if the remote control 20 is forgotten, so it is desirable to impose a penalty when the remote control 20 is forgotten. For example, the main unit 11 may sound a siren at the pick-up station if the remote control 20 is forgotten. To avoid this, the pick-up station may be set up so that the engine of the vehicle 50 cannot be turned off. Since area detection is not possible, the main unit 11 may impose a penalty by recording the fact that the remote control 20 has been forgotten in a memory unit such as an SD card. The memory unit may be, for example, a memory medium provided in at least one of the first drive recorder 17 and the second drive recorder 18, or may be a memory unit separate from these.

The area detection may be a function that detects whether the remote control 20 or a person holding the remote control 20 is in the detection area, and a method other than the above may be adopted. The area detection may be a function that does not require the use of the remote control 20, and another method may be adopted for detecting whether a person who is to check is in the detection area.
In this way, an appropriate notification (for example, sounding a siren or sending a message to the remote control 20) can be made based on the area detection.

[9. Other configuration or operation example of the abandoned vehicle monitoring system 100: Part 5]
The configuration using the position information acquisition unit described in [7. Other configuration examples or operation examples of the abandoned object monitoring system 100, part 3] and the configuration related to area detection described in [8. Other configuration examples or operation examples of the abandoned object monitoring system 100, part 4] may be combined as follows. In addition, the following configuration examples or operation examples can be appropriately combined with other configuration examples or operation examples in this specification.

Based on the location information acquired by the location information acquisition unit, the main unit 11 first registers locations using GPS, and distinguishes between locations where a siren may be sounded and locations where a siren may not be sounded. Location registration is a function for registering locations where a siren may be sounded (an example of an alarm) and locations where a siren may not be sounded. In the following, an area defined based on a registered location may be referred to as a "registered area" or a "GPS registered area". The registered area is, for example, an area of a predetermined size (for example, a circular range with a radius of 50 m) centered on the registered location. The location information acquired by the location information acquisition unit (for example, the positioning result of the GNSS receiver) may be used not only for the purpose of location registration, but also for operation management (for example, management of information on when and where the vehicle was driven). It is preferable that the location registration and the registration of locations where a siren may be sounded and locations where a siren may not be sounded be configured so that a user can use an external device such as a personal computer 22 to perform the location registration and the registration of locations where a siren may be sounded. The external device transmits the registered information to the main unit 11. The main unit 11 stores (registers) the received information.

Next, the relationship between location registration, area detection by the remote control 20, and button operation of the remote control 20 is as follows. First, when the vehicle 50 is in a siren-enabled location and the remote control 20 is outside the area of area detection, the main unit 11 activates a siren and notifies the remote control 20. If the remote control 20 is within a communication range with the main unit 11, it issues an alarm (e.g., an alarm sound). In this case, the remote control 20 accepts a button operation by the driver to stop the alarm (e.g., an alarm sound) of the remote control 20 and transmits a signal to the main unit 11 instructing it to stop activating the siren. When the main unit 11 receives this signal, it stops the siren. If the remote control 20 is outside the communication range with the main unit 11, the remote control 20 does not issue an alarm. Therefore, the remote control 20 does not operate a button to stop the alarm, and even if a button is operated, the alarm siren does not stop in the vehicle 50.

When the vehicle 50 is in a location where siren activation is permitted and the remote control 20 is within the area detection area, the main unit 11 does not activate the siren but reports this to the remote control 20. The remote control 20 issues an alarm (e.g., an alarm sound) in response to this report. Here, if no button operation is performed for a certain period of time to stop the alarm on the remote control 20, in other words, if a signal instructing to stop the siren activation is not received from the remote control 20, the main unit 11 activates the siren. Also, in response to button operation on the remote control 20, the alarm on the remote control 20 (e.g., an alarm sound) and the siren on the vehicle 50 side stop in the same manner as described above.

If the vehicle 50 is in a location where siren activation is prohibited and the remote control 20 is outside the area detection area, the main unit 11 will not activate the siren but will report it to the remote control 20. Also, the remote control 20 will activate an alarm (e.g., an alarm sound) if it is within a communication range with the main unit 11. In this case, the remote control 20 will stop the alarm (e.g., an alarm sound) of the remote control 20 upon receiving a button operation from the driver. The siren will not be activated. If the remote control 20 is outside the communication range of the main unit 11, the remote control 20 cannot activate an alarm (e.g., an alarm sound).

When the vehicle 50 is in a siren-prohibited area and the remote controller 20 is in an area detection area, the main unit 11 does not activate the siren and does not notify the remote controller 20.
In this way, by appropriately combining location registration, area detection, and button operations on the remote control, it is possible to issue an alert (for example, sounding a siren or reporting to the remote control 20) when appropriate.

The area detection of the remote control 20 may be performed by setting two types of areas. Figures 4A to 4C are state transition diagrams of an embodiment of the present invention. In this example, the vehicle 50 is monitored based on the position determined by the GPS. In the example of Figures 4A to 4C, one remote control 20 is used, and the vehicle 50 does not issue an alarm if it is within the detection area. There are area 1 and area 2 as detection areas. Area 2 is a range larger than area 1. Area 1 is the periphery of the vehicle, and area 2 is within a radius of 100 m from the vehicle. Area 1 is set by narrowing the area when it is not possible to confirm disembarking, assuming that the driver is near the vehicle 50, and area 2 is set by widening the area when a forgotten item or a child gets on the vehicle 50 before the driver (the driver arrives later) during monitoring, assuming that the driver is not near the vehicle 50.

The remote control 20 is carried along with the key to the vehicle 50. That is, it is assumed that the remote control 20 is together with the key and carried by the driver or located within the park. Only the doors at the entrance and exit of the vehicle 50 are monitored. The dashed and dotted lines indicate when the door is open, and the dashed lines indicate when the door is closed. In any state, it is reset when the ACC is turned on. When the ACC is on, the location information of the vehicle 50 (e.g., GPS location information) is recorded as a log, and events such as ACC on/off, door open/closed, monitoring status, SW operation (disembarkation confirmation switch 14, emergency call switch 15), remote control communication (communication between the main unit 11 and the remote control 20), and siren activation are recorded as a log along with the date and time.

[10. Other configuration or operation example of the abandoned vehicle monitoring system 100: Part 6]
The following configuration examples or operation examples can be appropriately combined in two or more. Also, the following configuration examples or operation examples can be appropriately combined with other configuration examples or operation examples in this specification.

We will now explain modified examples of the rear button (disembarkation confirmation switch) (hereinafter simply referred to as the "button") 14. It is desirable to prevent the button 14 from being pressed by people being picked up or dropped off (for example, kindergarteners, children at special needs schools, elderly people, etc.). Therefore, the following first to third example configurations may be adopted.

The first example relates to a design for the button 14 itself. For example, a lock may be provided on the button 14 itself so that the button 14 cannot be pressed unless the lock is released. Also, a cover may be provided to allow access to the button 14 so that it cannot be easily opened.

Also, the main unit 11 may only deactivate the alarm when the button 14 is pressed in a specific manner. In particular, if there is only one button 14, the alarm may be deactivated only when the button 14 is pressed, for example, in Morse code. In this case, the way the button is pressed may differ depending on the person or role (driver, passenger, etc.), and the main unit 11 may have a function to identify and record which person pressed the button. There may be multiple buttons 14, and the alarm may be deactivated when the multiple buttons 14 are pressed correctly, or the button 14 may be a numeric keypad, and the main unit 11 may deactivate the alarm when the numbers entered on the numeric keypad match the numbers set in advance.

Also, the buttons 14 may be placed in multiple different locations, and the main unit 11 may determine that confirmation is complete when multiple predetermined buttons 14 are pressed from among the different locations. In this case, the main unit 11 may determine that confirmation is complete when multiple predetermined buttons 14 are pressed in a predetermined order. Also, it is advisable to provide an indication that a pressed button 14 can be distinguished from an unpressed button 14, such as by turning on a lamp provided for that button.

In addition, when a route bus or the like that already has a button as a disembarking confirmation switch is used for transportation, the existing disembarking confirmation switch can be connected to the abandoned vehicle monitoring system 100, and the main unit 11 can have a function to assign an alarm cancellation function to the existing disembarking confirmation switch. In this case, the disembarking confirmation switch corresponding to the seat can be connected, and a function to use it for roll call (counting the number of passengers) can be provided.

The second example relates to the location where the button 14 is installed. For example, the button 14 may be installed on the underside of the seat. In this case, the confirmed operation can be performed while checking whether someone has crawled under the seat. The button 14 may also be installed on the underside of the seat at the rearmost position. Furthermore, the button 14 may be installed on the underside of the seat in each row or every other row.

The relationship between the installation position of the human detection sensor, the detection range of the human detection sensor, and the installation position of the button 14 may be set so that the installation position of the button 14 is a position where the human detection sensor (e.g., sensors 12a to 12d) is difficult to detect. In this case, the human detection sensor may be a human detection camera that is a camera for detecting people. The button may also be provided inside a housing integrated with the sensor. In this case, there is an advantage that wiring is easier. Furthermore, the installation position of the button 14 may be set to a position where the human detection sensor is difficult to detect, and the button 14 may be provided inside a housing integrated with the sensor. In other words, the sensor itself may be installed under the seat (with the detection range facing upwards).

A button 14 (which may be called a stop switch) may be provided near the driver's seat. A button 14 may also be provided in the trunk. A button 14 for the tour conductor to press may be provided under the tour conductor's seat, near the boarding door, or on the tour conductor's portable remote control, and the tour conductor may press this button 14 once all the children have disembarked. When the button 14 is pressed, an alarm sounds, and the driver or another person may check the seats again and press a button on the back to stop the alarm. Since the tour conductor may forget to press the button, it is advisable for the main unit 11 to start an alarm sound when the boarding door is closed. The main unit 11 may not sound an alarm if the tour conductor button on the remote control is pressed after the alarm sound has been stopped, but may sound an alarm if the door button is pressed.

The third example relates to a method of indicating completion of confirmation using something other than a button. For example, the alarm may be released by holding up an object such as an employee ID or a smartphone. In this case, the main unit 11 may have a function for identifying the person who held it up. In this case, a technology such as NFC may be used. The main unit 11 may stop the alarm when it is recognized by gesture detection that a specific seat is being confirmed. Here, the gesture may be a pointing gesture (towards the seat (downward)), or the gesture may be a specific gesture indicating completion of confirmation (such as making a circle with the hands). The above-mentioned "specific seat" may be the last seat, or it may be all the seats in the row.

In addition, when a crouching motion is confirmed by posture detection, processing may be performed in the direction in which the confirmation motion was made.

[11. Other configuration or operation example of the abandoned vehicle monitoring system 100: No. 7]
The following configuration examples or operation examples can be appropriately combined in two or more. Also, the following configuration examples or operation examples can be appropriately combined with other configuration examples or operation examples in this specification.

The relationship between the situation, the viewer, and the device functions (for example, functions realized by the main unit 11) may be as shown in Table 1. Note that the configurations shown in parentheses in the table are configurations that are more preferable to have, and it is also possible to have a configuration that does not include these.

[12. Other Configuration Examples or Operation Examples of the Abandonment Monitoring System 100: No. 8]
The following configuration examples or operation examples can be combined in two or more suitable combinations. In addition, they can be combined with other configuration examples or operation examples in this specification. As other embodiments for preventing items from being left behind, the first to third examples will be described.

In the first example, an application program (hereinafter referred to as the "app") of a smartphone (hereinafter referred to as the "smartphone"), which is an example of a terminal device, automatically switches the smartphone camera to video recording mode when it detects that the vehicle has entered a pre-registered drop-off location or a parking spot after disembarking using the smartphone GPS (GPS function of the smartphone), a specific Wi-Fi (registered trademark) ID detection, or a beacon (BT beacon) detection in Bluetooth communication. The screen displays the video being recorded in real time, and is also provided with a still image capture button and a disembarking confirmation switch 14 (hereinafter also referred to as the "left behind confirmation completion button"). In this example, the driver or passenger holds the smartphone and takes pictures of each row of vehicles to check whether anything has been left behind. Then, when there is something to inform the business, such as a forgotten item or dirt that needs cleaning, the still image capture button is pressed, and the video is transmitted to the business's terminal or the employee's smartphone, etc., and can be viewed from the business's terminal or the employee's smartphone, etc.

In this example, if the abandoned vehicle confirmation completion button is pressed too soon after the start of recording, the pressing is invalidated if the video recording time is short. Alternatively, the abandoned vehicle confirmation completion button may be made unable to be pressed for a predetermined time from the start of recording. In this case, for example, the button may be grayed out or a message saying "Please check your seat" may be displayed.

In the second example, a marker is provided in a position far from the boarding/alighting door (e.g., at the rear of the vehicle), and when the marker is recognized as being a predetermined size or larger (e.g., the size when photographed at a position where confirmation is complete), a function is provided that automatically completes confirmation without pressing a confirmation completion button. In this example, confirmation is not completed when the marker is recognized as being smaller than the predetermined size. When the marker is detected in this position for a predetermined period of time or longer, a notification such as "Please check all the way to the last seat and point the camera at the marker" can be issued. The marker may be a QR code (registered trademark), but it may also be an image of a predetermined object inside the vehicle, such as an emergency exit sign.

The relationship between the size of the marker and the approach distance changes depending on the angle of view of the smartphone camera, so it is a good idea to take a picture of the marker from the confirmed position for each smartphone in advance and register it as a comparison image, and then make a judgment based on the relationship in size between that image and the captured image.

In a third example, the "smartphone" in the first and second examples above may be a wearable camera with smartphone-like functions, an action camera, or other portable, battery-powered dedicated camera. Such a dedicated camera may be a camera from a live broadcast system that provides parents with updates on how their children are doing at daycare.

13. Other embodiments
Further modifications will be described below. The following modifications can be combined in two or more suitable combinations. In addition, the modifications can be combined with other configurations or operation examples in this specification.

The abandonment prevention system may have a temperature notification function using a temperature sensor. This abandonment prevention device may have functions such as activating a human presence sensor and taking pictures with an in-car camera when the temperature reaches or is close to reaching a temperature that would be dangerous if people were present, and transmitting the in-car image, the detection status of people, and the temperature to an office.

The introduction of child monitoring tags (with GPS functionality) is also being considered. Therefore, it would be good to use this GPS location information for picking up and dropping off children and for roll calls (e.g., counting the number of people). Specifically, when a child has not yet arrived at the pick-up or drop-off location based on the GPS functionality of the monitoring tag, the child abandonment prevention system may notify the child (e.g., by display or voice) from the vehicle or the tour conductor's smartphone, and may provide a button to postpone pick-up or drop-off, or may automatically send a postponement email to the guardian's smartphone. The child abandonment prevention system may also count the number of passengers when the GPS location of each child matches the GPS location of the vehicle 50 "while moving." When the vehicle 50 is stopped, passengers are getting on and off, so the information may not be used for counting.

The anti-abandonment system should have a function that uses GPS location information to compare the number of children who have been on board with the number of children currently in the facility after a certain time (boarding and disembarking time +α) since the vehicle 50 arrives at the facility, and if there is a difference, sends a notification from the vehicle, an office terminal, a staff member's smartphone, etc. At this time, the child who is the difference may be identified and their name, etc., may be notified along with a map of their currently detected location, etc.

It may also be linked to security cameras. Specifically, the abandonment prevention system is equipped with a connection part that connects to the video signal line of an existing security camera at the entrance of the nursery or to a wireless communication system such as Wi-Fi, and counts the number of people entering from the entrance using image recognition. This counting should start a specified time after the person driving the child to or from the nursery enters the nursery. The number of people getting off may also be counted using a (security) camera installed to capture an area including the boarding and alighting entrance of the shuttle vehicle from outside, or a camera inside the vehicle. If there is a discrepancy, it is recommended to have a function to notify from the vehicle, office terminal, employee's smartphone, etc.

It would also be a good idea to use a tilt-type security camera and, when the person arriving at the nursery arrives, change the direction of the tilt-type camera (or the zoom range, if zoomable) to face either the facility entrance or the person. Once the count is complete, it would also be a good idea to have a function to return the camera to its original shooting range.

Figure 5 is a block diagram showing the configuration of an abandoned vehicle monitoring system according to another embodiment of the present invention. The same configuration as that of the example in Figure 1 will not be described. The monitoring system 101 is equipped with a valet switch 23. The valet switch 23 is provided in the driver's seat and connected to the main unit 11. A siren 24, a speaker 25, a GPS receiver 26, and an indicator 27 are also connected to the main unit 11. Furthermore, a wireless communication module 28 that can be connected to a mobile phone network or WiFi is connected to the main unit 11. The wireless communication module 28 can communicate with a mobile terminal 30 via the Internet. A memory card 29 reader is also connected to the main unit 11. Note that in Figure 5, the constant power supply (+B) and GND are omitted due to space restrictions.

Figure 6A is a side view of a vehicle according to another embodiment of the present invention, and Figure 6B is a plan view of the interior of the vehicle according to another embodiment of the present invention. Regarding Figures 6A and 6B, the same configuration as Figures 2A and 2B will not be described. As shown in Figures 6A and 6B, the valet switch 23 is installed on the dashboard of the driver's seat.

Figure 7 is a diagram showing a method for mounting a sensor unit according to an embodiment of the present invention. A mounting hole is drilled in the ceiling lining 71, and the ceiling lining 71 is sandwiched between a mounting screw 72 and a sensor unit 73 to fix the sensor unit 73. A washer 74 is sandwiched between the mounting screw 72 and the ceiling lining 71 and tightened. The sensor unit 73 comprises a Doppler sensor 75 and an IR sensor lens 76. In this example, the sensor unit 73 is fixed to the ceiling lining 71 at two points (two mounting screws 72) to prevent the sensor unit 73 from rotating.

Figure 8 shows a method of mounting a sensor unit in another embodiment of the present invention. A hole for the IR sensor and a hole for the clip are drilled in the ceiling lining 71, and the sensor unit 73 is fixed to the ceiling lining 71 with a washer clip 77 for the IR sensor and a clip 78. The washer clip 77 is used to consider the appearance when the hole for the IR sensor is drilled, and also to fix the sensor unit 73 in place.

Figure 9 is a block diagram showing the configuration of an abandoned vehicle monitoring system according to another embodiment of the present invention. The abandoned vehicle monitoring system 90 includes an on-board camera 91a, an off-board camera 91b, a GPS receiver 92, a verification system 93, a management system 94, an administrator terminal 95, and a guardian terminal 96. The on-board camera 91a, the off-board camera 91b, and the GPS receiver 92 are provided in the vehicle 50. The verification system 93 is also provided in the vehicle 50. The management system 94 is provided on a communication network. The administrator terminal 95 is provided in a facility such as a kindergarten or nursery school, and the guardian terminal 96 is carried by the guardian of the child.

The boarding camera 91a is installed facing outward at the boarding/alighting entrance 52 so as to capture the faces of children getting on. The disembarking camera 91b is installed facing inward at the boarding/alighting entrance 52 so as to capture the faces of children getting off. The boarding camera 92a and the disembarking camera 93b transmit the captured images to the matching system 93. The GPS receiver 92 transmits location information based on the received radio waves to the matching system 93. The matching system 93 comprises a database 931 as a storage device, a matching device 932, and a communication device 933. The database 931 stores facial images of registered children together with detailed information about the children (such as name, age (class), boarding and alighting location, etc.).

The matching device 932 acquires images transmitted from the on-board camera 91a and the off-board camera 91b, matches them with images stored in the database 931, and identifies the child whose face was photographed by the on-board camera 91a or the off-board camera 91b. The matching device 932 may have a machine learning model that has learned the facial images of registered children, and may identify the child by inputting the facial images of the child photographed by the on-board camera 91a and the off-board camera 91b into the machine learning model. The machine learning model may use an SVM, may use principal component analysis, or may use a neural network.

The on-board camera 91a and the off-board camera 91b may continuously capture images and transmit the images to the matching device 932. In this case, the matching device 932 may continuously perform face detection processing and start the above-mentioned face recognition processing by detecting a face in the face detection processing. A machine learning model may also be used for this face detection.

The communication device 923 is a device that can connect to the Internet via a mobile phone network. The communication device 923 transmits information about the child identified by the matching device 922 to the management system 94, together with information about whether the child is boarding or disembarking (whether the matching was made from the image from the boarding camera 91a or from the image from the disembarking camera 91b), the location information received from the GPS receiver 92, and information about the time at that time.

The management system 94 includes a communication device 941, a status management device 942, and a database 943. The communication device 941 receives information on children, boarding and alighting information, location information, and time information transmitted from the collation system 93. The status management device 942 stores the information received by the communication device 941 in the database 943. In the database 9542, a record is generated for each pick-up and drop-off trip of the vehicle 50, and each record stores information on each child's boarding and alighting. In this record, when a child boards the vehicle, it is recorded as boarding, and when a child alights, it is recorded as alighting, and for children who board the vehicle but do not alight after alighting, it is recorded as being aboard. Therefore, by referring to this database 943, it is possible to confirm whether each child is aboard or not.

The status management device 942 transmits the information stored in the database 943 via the communication device 941. The database 943 also stores information on the parent terminal for each child. Each time the status management device 942 obtains new boarding or disembarking information for a child from the communication device 941, it transmits the boarding and disembarking information to the administrator terminal 95 and the parent terminal 96 corresponding to that child via the communication device 941. This boarding and disembarking information includes information on the relevant child, information on the boarding or disembarking status, the boarding or disembarking location, and the boarding or disembarking time.

The status management device 942 also periodically refers to the database 943, and if there is a child who has not yet disembarked after a predetermined time (e.g., one hour) has elapsed since boarding, it sends alert information via the communication device 941 to the administrator terminal 95 and the parent terminal 96 corresponding to that child.

According to this abandoned vehicle monitoring system 90, the face of the child who boards the vehicle is photographed and facial recognition is performed to identify the child who has boarded the vehicle, and in the latter case, the face of the child is photographed and facial recognition is performed to identify the child who has disembarked. By managing the boarding and disembarking information in a centralized manner, it is possible to know whether a child is on board the vehicle. Therefore, it is possible to know the presence of a child who is on board at a time when he or she should not be (i.e., who has been left behind in the vehicle 50).

In addition, in the above-mentioned abandoned vehicle monitoring system 90, the database 931 and/or the matching device 932 of the matching system 93 may be provided on a communication network external to the vehicle 50, and may be integrated with the management system 94.

The boarding camera 91a and the disembarking camera 91b may be configured as a single camera. In this case, the single camera may be provided with an instruction function for specifying whether to board or disembark. Alternatively, during the pick-up time slot in which the pick-up service is expected and the drop-off time slot in which the drop-off service is expected, the first time the camera recognizes the passenger it may be determined that the passenger has boarded, and the second time the camera recognizes the passenger it may be determined that the passenger has disembarked.

The specified time for issuing the alert information may also be set for each child as a time with a margin added to the expected ride time (for example, 20 minutes with a 10-minute margin added for a child with an expected ride time of 10 minutes, or 35 minutes with a 15-minute margin added for a child with an expected ride time of 20 minutes).

In addition, in the above-mentioned abandoned vehicle monitoring system 90, the child is identified using the appearance (image) of the child's face as biometric information, but other biometric information such as fingerprints, veins, irises, and voiceprints may be used to identify the child getting on and off the vehicle. Alternatively, an ID may be stored on a wireless tag carried by the child, and the wireless tag may be read using an antenna and reader when the child gets on and off the vehicle to identify the child getting on and off the vehicle.

Alternatively, the following may be done.
(1) The abandoned vehicle monitoring system 100 may be provided with a connection unit for connecting to an alarm system that starts an alarm when the engine of the vehicle is turned off and stops the alarm when a button installed at the rear of the vehicle in a position where the child cannot press is pressed, as an abandoned vehicle monitoring system that is retrofitted to the alarm system. The connection unit may be configured to receive a signal from the alarm system, for example, by having a connector for electrically connecting to the alarm system. The abandoned vehicle monitoring system 100 may be an abandoned vehicle monitoring system that controls a function for detecting a person (passenger) in the vehicle or a function for recording a person in the vehicle based on an electrical state acquired through the connection unit. In this way, the abandoned vehicle monitoring system 100 itself can perform control according to the detection result of a person in the vehicle, even if it does not have a sensor for detecting a person (passenger) in the vehicle. The control according to the detection result of a person in the vehicle can be various controls described in this specification. The function for recording a person in the vehicle may be, for example, at least one of the first drive recorder 17 and the second drive recorder 18.

(2) The drive recorder installed in the vehicle may have a power supply function that starts an alarm when the vehicle engine is turned off and operates while the alarm is sounding when a button attached to the rear of the vehicle in a position that cannot be pressed by the child is pressed. In other words, the child may be made to press a button to confirm that the child has left the vehicle. The power supply function may be realized, for example, by a control unit that controls the supply of power from a power source. The power source may be, for example, a battery built into the drive recorder or an external battery to the drive recorder, or a power source on the vehicle side. The control unit may receive power from the power source to record even after the vehicle engine is turned off and the alarm is started, and when the button attached to the rear of the vehicle in a position that cannot be pressed by the child is pressed, the control unit may end the recording and turn off the power of the device itself without receiving power from the power source. The drive recorders may be, for example, a first drive recorder 17 and a second drive recorder 18. The button located in a position where children cannot press may be the "button located in a position where children cannot press" in (1) or it may be the exit confirmation switch 14.

(3) The above (1) or (2) video recording may be provided with a function that allows it to continue even when the engine is turned off, and may be stopped when it detects that a button installed at the rear of the vehicle in a position where children cannot press it is pressed. The stopping of recording triggered by the detection of the button being pressed may be set to stop a predetermined time after the detection. In this case, "stopping" may be a complete stop, or it may be a transition to parking surveillance recording. Parking surveillance recording is a mode for recording while the vehicle is parked, and is a different mode from the above recording mode, and is a mode that allows long-term recording while saving storage resources, for example by lowering the frame rate, or a mode for recording when an impact or other specified event is detected in the vehicle while parked.

(3-1) The above "function that continues even when the engine is turned off" should preferably be a function that starts recording video when the engine is turned off, but should also record a specified time before the engine is turned off. In the configurations of (1) and (2) above, an alarm sounds when the engine is turned off, so there is a possibility that children may get on and off the car without turning off the engine. Even in such a case, however, it is possible to record video including the children getting on and off. The specified time before the engine is turned off should preferably be several minutes, and should preferably be configurable.

(3-2) The above (1) and (2) recordings may be recorded as events other than parking monitoring events, such as in the "Exit Confirmation" folder.

(3-3) In addition to the above-mentioned "button at the rear that cannot be pressed by the children," a button for the children that can be pressed by the children may be provided, and the recording of the above (1) and (2) may be recorded as two separate events.

(4) The "children's button located where a child can press" in (3) may be a large button, and may be configured so that even if the engine is turned off, at least the part that should be pressed is lit up by a motion sensor. Also, this child's button may be made to light up when the motion sensor detects a motion even if it is not being pressed or the engine is turned off, and to light up brightly when pressed. The motion sensor may be any of the sensors 12a to 12d described above. The control of lighting up the child's button may be performed by the main unit 11, or may be performed by a control unit provided in the child's button.

(5) The "children's button in a position where they can press it" is located near the boarding/alighting entrance 52, and children are instructed to press it when getting on and off. This reduces resistance to pressing the button when left behind. In this case, the main unit 11 may detect whether the boarding/alighting entrance 52 is open or closed, and count the number of boardings and alightings when the button is pressed with the boarding/alighting entrance open. For example, the main unit 11 may set a relationship between time and location, such as counting the number of boardings when the time is morning and the current location is somewhere other than the kindergarten, and counting the number of alightings when the time is afternoon and the current location is somewhere other than the kindergarten, and may compare the setting with the current state to determine which number to count. It is recommended that the main unit 11 counts multiple presses as one.

In relation to the "children's button located where they can be pressed," the following (5-1) may be adopted.
(5-1) The "children's button located where children can press" functions as a button that counts the number of people who get on and off the vehicle 50. Children touch the button once when they get on and once when they get off, so that it is possible to know that the number of children getting on and off does not match, and it is expected that children will not be left behind. The "children's button located where children can press" may be attached to the vehicle 50 or may be hand-held by staff members. In addition, the "children's button located where children can press" may have a cute design or mechanism that children will want to press, such as a button with a specific pattern such as a floral pattern or a character that is popular with children. In this way, a system for counting people can be introduced at a lower cost than sensors or existing entrance IC card systems.

(6) The abandoned vehicle monitoring system 100 may be equipped with a camera for capturing an image of the face of a person who has boarded a vehicle, and may send the image of the face of the person to an external device such as a server, a smartphone, or a personal computer. The process of transmitting the image of the face of the person who has boarded a vehicle may be performed by the main unit 11, or may be performed by a communication function provided in the camera itself. The camera for capturing an image of the face of the person who has boarded a vehicle may be integrated with the first drive recorder 17 or the second drive recorder 18, or may be a separately provided camera.

(6-1) The above-mentioned "external device such as a server, smartphone, or personal computer" may classify images (photos) of the faces of people who get on and display them like an album recording their growth.

(7) The abandoned vehicle monitoring system 100 may have a function to detect when the vehicle 50 is locked, and the main unit 11 may have a function to output a sound loud enough to wake up anyone in the vehicle 50 when the lock is detected or a predetermined time (up to a few minutes) shortly after the lock is detected. This makes it possible to wake up a person who has been left behind before they suffer from heatstroke.

(8) When the abandoned vehicle monitoring system 100 detects that there is a person inside the vehicle with the engine turned off, the main unit 11 may control the vehicle to perform a predetermined operation, in particular to start the engine, open the windows, or operate the air conditioner. In this way, the predetermined operation is preferably a vehicle operation that is desirable for ensuring the safety of the people inside the vehicle, but may also be an operation that is useful for notifying people outside the vehicle that there is a person inside the vehicle.

(9) The abandoned vehicle monitoring system 100 may include multiple types of sensors that detect the presence of a person in the vehicle, and the main unit 11 may have a function to transmit or record information about which type of sensor detected the person. For example, whether the detection was made by a millimeter wave radar, a microwave sensor, a pyroelectric sensor, a mat, an AI camera, or an ultrasonic sensor may be recorded and used for (manufacturer) diagnosis of whether there is a false detection or a malfunction.

(10) The abandoned vehicle monitoring system 100 may have a function of providing multiple sensors in different locations inside the vehicle to detect the presence of a person inside the vehicle, and superimposing a display showing the position and detection range of the detected sensor on the image of the viewer that displays the image of the camera capturing the inside of the vehicle 50. The sensors may be the sensors 12a to 12d described above. The function of the viewer may be realized by a device that plays (displays) the image captured by the camera, and may be realized by the function of the first drive recorder 17 or the second drive recorder 18, for example, or by a device other than a camera, such as a personal computer 22. In addition, a program for realizing the function of the viewer may be distributed to a computer via a network.

(11) The abandoned vehicle monitoring system 100 may further include a device that provides multiple sensors in different locations within the vehicle to detect the presence of a person inside the vehicle and a device that notifies the detected location by voice. The sensors may be the sensors 12a to 12d described above. The device that notifies the person may be the main unit 11 or another device. The method of notification may be that the main unit 11 issues a voice to people around the vehicle 50, or the main unit 11 may send a report to the transceiver 20, the monitoring terminal 21, or the personal computer 22 to notify the person.

(12) Abandonment becomes a problem when a child is left behind when the vehicle engine is turned off, the driver gets out of the vehicle, and all the doors are closed. In this case, the abandoned child monitoring system 100 may have a function in which, under the conditions that the engine is off, the presence of the driver is not detected using a state detection means for detecting the state of the driver such as a seating sensor in the driver's seat 51, a DMS (Driver Monitoring System), or a simple pyroelectric sensor, and all the doors of the vehicle 5 are closed, the main unit 11 issues an alarm by sounding an alarm from the vehicle 50, and the alarm is turned off by a predetermined operation of an alarm sound turning off unit provided in the rear of the vehicle 50. The alarm may be issued from the remote control 20 instead of or in addition to the vehicle 50. The alarm sound turning off unit may also be the exit confirmation switch 14. The main unit 11 may not issue an alarm such as sounding an alarm when the engine is on. When the presence of a driver is detected by a state detection means such as a seating sensor in the driver's seat 51, a DMS, or simply a pyroelectric sensor, the main unit 11 may be configured not to sound an alarm or issue an alarm. Also, the main unit 11 may be configured not to sound an alarm or issue an alarm when all doors are not closed. In this way, it is possible to prevent the driver from panicking in response to the alarm and taking inappropriate driving actions, and it is also possible to prevent the driver from being left behind.

(13) Abandonment becomes a problem when the door is locked while a child is left behind. Therefore, when the main unit 11 detects that the door of the vehicle 50 is locked, it may cancel the door lock (for example, without locking the door) and issue an alarm including an alarm sound from the vehicle 50 with a voice such as "The door has not been locked yet. Please check if anything has been left inside the vehicle and perform the specified operation." For example, the main unit 11 may issue an alarm when it detects that the door of the vehicle 50 is locked. For example, the main unit 11 may issue an alarm when it detects that the vehicle 50 has been locked by operating the remote control 20 or that the vehicle 50 has been locked from outside the vehicle 50. The main unit 11 may receive a signal indicating that the vehicle has been locked from the remote control 20 or from the vehicle 50. Furthermore, the remote control 20 may issue a similar alarm.

Furthermore, the driver may subsequently cancel the alarm by performing a predetermined operation on an alarm canceling unit (e.g., exit confirmation switch 14) provided at the rear of the vehicle 50, and when the door of the vehicle 50 is locked again from the remote control 20 or from outside the vehicle 50 after the alarm has been cancelled, the main unit 11 may lock the doors. This can prevent the vehicle from being left behind when the driver gets out of the car in a parking lot and tries to lock the doors for the first time, and can also reduce the possibility of the driver behaving inappropriately and causing an accident when an alarm is sounded at other times, and can also prevent the driver from forgetting to lock the doors.

(14) In some situations, such as when filling up with gasoline, it is troublesome to stop the alarm every time. Therefore, the main unit 11 may determine whether or not the vehicle is in a state to fill up with gasoline, and when the vehicle is in a state to fill up with gasoline, the main unit 11 may be configured not to issue an alarm even in the above states (12) and (13). Filling up with gasoline at a gas station takes only a short time, and it is unlikely that the vehicle will be left behind. However, even if a child is in the vehicle, opening the entrance and exit door at the gas station may be dangerous. In this way, the driver can be prevented from taking inappropriate actions when filling up with gasoline at a gas station. The state to fill up with gasoline may be, for example, a state in which the driver is about to fill up with gasoline. The state may be detected based on a fuel filler image taken of the area around the fuel filler, a switch, or whether the position of the vehicle 50 (for example, the position measured by GNSS) is a gasoline station or a previously registered location.

(14-1) The main unit 11 may be configured to stop all alarms when the fuel filler cap is open. In this case, the main unit 11 returns to an alarm state when the fuel filler cap is closed. In this way, the vehicle inspection company only needs to be informed that no alarm will be issued if the fuel filler cap is open, and the main unit 11 returns to an alarm state simply by closing the fuel filler cap, so it is possible to prevent vehicles from being left behind with the alarms deactivated.

(15) The main unit 11 of the abandoned child monitoring system 100 may have a function of issuing an alarm based on the result of detecting the presence of a tag carried by a child in the vehicle. The tag may be a so-called smart tag having a function of wireless communication. The main unit 11 may detect the presence of the tag by communicating with the tag using a predetermined communication method that has a communication range within the vehicle. The communication method may be, for example, Bluetooth (registered trademark), but may be other than this. The tag may be provided on an item carried by the child. The item may be, for example, clothing worn by the child (e.g., a uniform), a name tag attached to the clothing, a bag carried by the child, or other items that the child carries on a daily basis. In particular, if the item carried is a name tag equipped with a smart tag, the smart tag and name tag have a high compatibility in terms of design in terms of size and thickness, making it attractive from the perspective of commercialization. Furthermore, smart tags have become quite inexpensive in recent years, so they could be an attractive product that could be accepted as a slightly more expensive name tag. This would also reduce the administrative work of staff (teachers). Given the current situation where long hours of overtime are the norm due to a shortage of childcare workers and other staff, this could be an incentive to introduce the system.

It is particularly preferable that the main unit 11 issues an alarm when it detects the presence of a tag if a certain condition is met, which indicates that no child should be in the vehicle. For example, if the main unit 11 detects the presence of a tag during a certain time period, such as after the kindergarten opens, it may report the presence to an external terminal, or may notify the presence by using a buzzer, alarm, or horn output. The certain time period may be the time when the kindergarten is open, such as from 8:30 a.m. to 12:00 p.m. The certain time period may be determined according to the schedule of the person to be detected, such as from 8:30 a.m. to 4:00 p.m. in the case of a nursery school or school. A staff member inputs information about the certain time period, such as schedule information, in advance via the personal computer 22, and this information is notified to the main unit 11. The main unit 11 may then determine whether or not the certain time period is based on this information.

(16) The portable object of (15) may further have a light-emitting function. The portable object may have, for example, an LED or other light-emitting body, and may have a function of making the light-emitting body emit light in dark conditions such as at night. In this way, it is possible to improve safety when walking in dark conditions such as at night. The portable object may have, for example, a light-emitting unit and a control unit. The control unit may make the light-emitting body emit light at a predetermined time when the surroundings are dark, such as at night. The portable object may further have a sensor (for example, an illuminance sensor) that detects the surrounding brightness, and the control unit may make the light-emitting body emit light when the brightness detected by the sensor is equal to or lower than a predetermined brightness. Alternatively, the portable object may have a switch or other operating unit, and the control unit may be configured to switch whether or not to make the light-emitting body emit light in response to the operation of the operating unit. Note that such a portable object may operate using a battery provided inside as a power source.

The belongings of (17), (15), or (16) may further include an IC chip as a storage unit that stores information about the child. The IC chip is easily integrated into a thin housing, and may store (contain) information such as the child's grade, name, and blood type. The IC chip may be configured to read information without contact. An external reading device such as a smartphone or tablet may read the information from the IC chip when the child boards the vehicle or arrives, and may record attendance in the attendance book based on the read information (for example, automatically record the attendance). This reduces the administrative work of teachers. Even if a child is injured in a bus accident, the child's blood type, allergies, and other medical conditions may be identified based on the information read from the IC chip, allowing appropriate treatment.

(18) The functions realized by the main unit 11 or the abandoned object monitoring system 100 are not limited to the main unit 11, and may be realized by other elements in the abandoned object monitoring system 100 as appropriate. Alternatively, they may be realized as part of the functions of a system other than the abandoned object monitoring system 100, such as a server device. The term "alarm" described in the above embodiment may be read as a warning, notification, notice, etc. In addition, the means used for the alarm (e.g., sound, display, light emission) and the content of the alarm (e.g., message content or display content) may be changed as appropriate within the scope that the purpose of the alarm can be achieved.

(19) In the above embodiment, an example was described in which the abandoned vehicle monitoring system of the embodiment of the present invention was applied to a bus that transports kindergarten children. However, the abandoned vehicle monitoring system of the embodiment of the present invention is not limited to buses used to transport kindergarten children, and may also be applied to buses used to transport elderly people.

Up to this point, the bus has been described as a shuttle bus that mainly transports kindergarten children, but the target audience may also be infants, pupils, students, and other children, or the elderly and other adults. Furthermore, the vehicle is not limited to being used for transportation. For example, the vehicle may be a vehicle other than a bus that runs on roads (e.g., a general vehicle), or a vehicle that runs on a track such as a train, monorail, or linear motor car (e.g., a public transport vehicle). It is preferable for the vehicle to be one in which it is not possible or difficult to see the entire interior of the vehicle from the boarding/alighting entrance or its vicinity, or from outside the vehicle, and in particular, a vehicle with seats. This is because people may be hidden behind the seats.

The object that may be left behind may be something other than a person. For example, an occupant's luggage such as a bag. Therefore, the above-mentioned abandoned object monitoring system may be applied to the construction of a system that suppresses the occurrence of an incident in which something other than the occupant is unintentionally left behind in the vehicle. In the case of detecting an object, for example, a function for performing object detection based on an image taken inside the vehicle may be adopted. For object detection, an object detection technology that performs image recognition on the taken image to identify the presence or absence of an object and its type may be used. The imaging function may be provided by the first drive recorder 17 or the second drive recorder 18, but other imaging devices may also be used. Furthermore, the present invention is not limited to vehicles, and may also be applied to aircraft, elevators, gondolas, and other transportation equipment or vehicles.

(20) Some of the controls and operations performed by each device described in each of the above embodiments may be omitted or modified. Furthermore, the configuration described in the above embodiments as transmission may be interpreted as an output configuration. Output may be an output other than transmission, such as recording (storage) or printing. Furthermore, the functions of the main unit 11 and other control units may be realized by one or more hardware resources, one or more software resources, or a combination of these. For functions realized by software resources, a program for realizing the function may be distributed via the Internet or other networks.

(21) Each function described in the above embodiment may be realized by one or more hardware elements, one or more software elements, or a combination of these. Furthermore, each function may be realized by a single device that is physically or logically coupled, or by two or more devices that are physically or logically separated.

The storage medium that stores the program described in the above embodiment is not limited to those described in the above embodiment, and may be any storage medium that can be read by a computer. Examples of computer-readable storage media include storage media of various storage methods such as semiconductor storage media, optical storage media, and magnetic storage media. Examples of computer-readable storage media include storage media built into a device that realizes functions based on a program, storage media external to the device, storage media such as a server connected to the device via an electric communication line (e.g., wired and/or wireless), and other storage media.

Furthermore, the functions realized by the program may be realized by programs such as, for example, application programs, operating systems, middleware, firmware, etc.

Furthermore, notification of the specified information is not limited to being done explicitly as long as the user is able to recognize the notification, but may also be done implicitly (i.e., without explicitly notifying the specified information).

The above-described embodiments and variants of the present specification can prevent people or objects from being left behind in vehicles, thereby, for example, ensuring human lives, enabling people to live safe and secure lives, and even contributing to the SDGs by realizing the development of cities where people can continue to live safely and securely.
