[0004] However, with the conventional technology, appropriate notification cannot be performed in accordance with the situation inside and outside the vehicle. For example, even in a situation where an alarm is unnecessary for the situation outside the vehicle, notification cannot be sent to the outside in cases such as when an infant or a pet is left behind in the vehicle. As described above, the problem to be solved by the present invention includes the above-mentioned problem as an example.

[0009] The embodiments for carrying out the present invention (hereinafter referred to as "embodiments") will be described below with reference to the drawings. However, the present invention is not limited to the embodiments described below. Furthermore, in the drawings, the same parts are denoted by the same reference numerals.

[0010] (Embodiment) [Configuration of the monitoring system] First, the configuration of the monitoring system according to the embodiment will be explained using Figure 1. Figure 1 is a diagram showing the configuration of the information processing system according to the embodiment. In Figure 1, monitoring system 1 is shown as an example of the information processing system according to the embodiment.

[0011] As shown in Figure 1, the monitoring system 1 may include an in-vehicle device 10 and a monitoring device 100. The in-vehicle device 10 and the monitoring device 100 are connected to each other via a network N, either by wire or wireless communication. Furthermore, the monitoring system 1 shown in Figure 1 may include any number of in-vehicle devices 10 and any number of monitoring devices 100.

[0012] The in-vehicle device 10 may be a dedicated sensor device built into or attached to the vehicle VEx, or it may be a recording device (dashcam) or the like installed in the vehicle VEx for crime prevention or to counter road rage.

[0013] Furthermore, the in-vehicle device 10 may consist of a sensor device and a notification device. As an example, the in-vehicle device 10 may be a composite device in which a sensor device and a notification device, which are independent of each other, are connected in a communicative manner. As another example, the in-vehicle device 10 may be a single device having both a sensor function and a notification function.

[0014] Furthermore, users can substitute their everyday portable terminal devices (e.g., smartphones, tablet devices, notebook PCs, desktop PCs, PDAs, etc.) with the in-vehicle device 10 by connecting a predetermined sensor to the device and installing a predetermined application. For example, a portable terminal device equipped with a predetermined sensor, or to which a predetermined sensor is connected, can be understood as the in-vehicle device 10 as referred to herein. When a portable terminal device is used as the in-vehicle device 10, it is installed, for example, on the dashboard of the vehicle VEx while driving.

[0015] Furthermore, the in-vehicle device 10 may be equipped with various sensors. For example, the in-vehicle device 10 may be equipped with various sensors such as distance sensors (microwave sensors, LiDAR (light detection and ranging) and other motion sensors), temperature sensors, microphones, GPS sensors, acceleration sensors, gyroscopes, cameras, and barometric pressure sensors.

[0016] The monitoring device 100 may acquire various types of data based on the sensor information detected by these sensors (for example, by analyzing the sensor information). For example, the monitoring device 100 may acquire information about moving objects inside and outside the vehicle from the motion sensor. Also, for example, the monitoring device 100 may acquire the temperature inside the vehicle from the temperature sensor. Also, for example, the monitoring device 100 may acquire sound from the microphone. Also, for example, the monitoring device 100 may acquire angular velocity from the gyro sensor. Also, for example, the monitoring device 100 may acquire video data of the outside taken from inside the vehicle VEx using a camera. Note that the monitoring device 100 may acquire sensor information detected not only by sensors provided in the in-vehicle device 10, but also by sensors provided in the vehicle VEx itself.

[0017] The monitoring device 100 is a device that provides notifications according to the situation inside and outside the vehicle. For example, the monitoring device 100 determines the situation from information on moving objects outside the vehicle and information on moving objects inside the vehicle, and sends a notification to the outside of the vehicle. In addition, the monitoring device 100 takes images of the inside and outside of the vehicle according to the situation inside and outside the vehicle, and transmits the captured images at the same time as sending a notification to the outside of the vehicle.

[0018] Here, if the in-vehicle device 10 is an edge computer that performs edge processing near the user, the monitoring device 100 may be, for example, a cloud computer that performs processing on the cloud side. That is, the monitoring device 100 may be a server device.

[0019] Furthermore, in the following embodiments, an example will be described in which information processing according to the embodiment is implemented in the monitoring system 1 by transmitting and receiving information between the in-vehicle device 10 and the monitoring device 100. However, the information processing according to the embodiment may be implemented only on the edge side, that is, only by the in-vehicle device 10. In this case, the in-vehicle device 10 may be configured to behave like the monitoring device 100, for example, by the information processing program according to the embodiment.

[0020] [Configuration of Monitoring Device] First, the monitoring device 100 according to the embodiment will be described with reference to FIG. 2. FIG. 2 is a diagram illustrating a configuration example of the monitoring device 100 according to the embodiment. As illustrated in FIG. 2, the monitoring device 100 includes a communication unit 110, a storage unit 130, and a control unit 120. Each unit included in the monitoring device 100 will be described below.

[0021] The communication unit 110 is implemented by, for example, a NIC (Network Interface Card) or the like. The communication unit 110 is connected to a network N via a wired or wireless connection, and transmits and receives information to and from, for example, the in-vehicle device 10.

[0022] The storage unit 130 is implemented by, for example, a semiconductor memory element such as RAM (Random Access Memory) or flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 130 stores information such as information related to moving objects, risk points, temperature information, audio information, information related to notification targets, images (including moving images and still images), notification settings, other information required for monitoring, and other information required for notification.

[0023] The control unit 120 is implemented using a CPU (Central Processing Unit), NP (Network Processor), FPGA (Field Programmable Gate Array), etc., and executes processing programs stored in memory. As shown in Figure 2, the control unit 120 has an external vehicle detection unit 121, an internal vehicle detection unit 122, an acquisition unit 123, and a notification unit 124. The individual parts of the control unit 120 will be described below.

[0024] The external detection unit 121 detects moving objects outside the vehicle. For example, the external detection unit 121 detects when a moving object approaches the vehicle. Examples of moving objects to be detected include people, vehicles, pets, and wild animals. The external detection unit 121 also uses position and direction information to detect when a moving object approaches the vehicle. The specific method of motion detection using position and direction information by the external detection unit 121 will be described later.

[0025] The in-vehicle detection unit 122 detects moving objects inside the vehicle. For example, the in-vehicle detection unit 122 detects predetermined movements of moving objects inside the vehicle. For example, the in-vehicle detection unit 122 detects movements that pose a risk of accident, such as violent or abnormal movements of people waiting inside the vehicle or pets.

[0026] Furthermore, the in-vehicle detection unit 122 detects predetermined conditions inside the vehicle. For example, the in-vehicle detection unit 122 detects the movement of a moving object inside the vehicle. For example, the in-vehicle detection unit 122 detects the movement of a moving object inside the vehicle to a predetermined position. Also, for example, the in-vehicle detection unit 122 detects the movement of a moving object inside the vehicle towards the driver's seat.

[0027] The acquisition unit 123 acquires information about the vehicle. For example, the acquisition unit 123 acquires the temperature inside the vehicle. For example, the acquisition unit 123 acquires information that the temperature inside the vehicle is 10°C. Also, for example, the acquisition unit 123 acquires information that the temperature inside the vehicle is 32°C.

[0028] Furthermore, the acquisition unit 123 acquires sounds from inside the vehicle. For example, the acquisition unit 123 acquires the voices of people talking inside the vehicle. Also, for example, the acquisition unit 123 acquires the sounds of pets barking inside the vehicle.

[0029] The notification unit 124, when the external detection unit 121 detects an approaching moving object to the vehicle and the internal detection unit 122 detects a moving object inside the vehicle, notifies the outside of the vehicle of a first notification and a second notification. For example, the notification unit 124 issues an audible alarm as the first notification and notifies the user terminal as the second notification.

[0030] For example, the notification unit 124 may issue a first notification by emitting an audible or luminous alarm around the vehicle. Furthermore, the notification unit 124 may issue a second notification to a pre-registered user terminal. This notification to the user terminal may include notifications sent via email, incoming calls, app notifications, or other functions provided by the user terminal.

[0031] Furthermore, the notification unit 124 may issue the notification that the second notification will issue as the first notification. Also, the notification unit 124 may issue the notification that the first notification will issue as the second notification. In addition, the notification unit 124 may report to the police and fire department at the same time as the first and second notifications.

[0032] Furthermore, if the external detection unit 121 does not detect an approaching moving object to the vehicle, and the internal detection unit 122 detects a predetermined state inside the vehicle, the notification unit 124 will send a second notification to the outside of the vehicle. For example, if the external detection unit 121 does not detect an approaching moving object to the vehicle, and the internal detection unit 122 detects a moving object inside the vehicle, the notification unit 124 will send a second notification to the outside of the vehicle. For example, if the external detection unit 121 does not detect an approaching moving object to the vehicle, and the internal detection unit 122 detects a predetermined movement of a moving object inside the vehicle, the notification unit 124 will send a second notification to the outside of the vehicle.

[0033] Furthermore, for example, if the external detection unit 121 does not detect an approaching moving object to the vehicle, the internal detection unit 122 detects a moving object inside the vehicle, and the temperature inside the vehicle acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 sends a second notification to the outside of the vehicle. In this case, the notification unit 124 can use a predetermined threshold for the temperature inside the vehicle, such as when it falls below 0°C or when it exceeds 35°C.

[0034] Furthermore, for example, if the external detection unit 121 does not detect a moving object approaching the vehicle, and the volume of the sound acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 sends a second notification to the outside of the vehicle. In this case, the notification unit 124 can use a predetermined decibel level, such as 80 decibels (dB), as the volume threshold. Also, for example, if the external detection unit 121 does not detect a moving object approaching the vehicle, the internal detection unit 122 detects a moving object inside the vehicle, and the volume of the sound acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 sends a second notification to the outside of the vehicle.

[0035] Furthermore, for example, if the notification unit 124 does not detect an approaching motion of a moving object to the vehicle by the external detection unit 121, detects a moving object inside the vehicle by the internal detection unit 122, and determines that the sound acquired by the acquisition unit 123 is of a predetermined type (for example, a child's voice or a pet's barking), it will send a second notification to the outside of the vehicle. At this time, the notification unit 124 may determine the predetermined type of sound by matching it with a predetermined frequency pattern, or it may determine it by using a machine learning model to estimate the type of sound based on the sound information as input.

[0036] Furthermore, for example, if the notification unit 124 does not detect an approaching motion of a moving object to the vehicle by the external detection unit 121, but detects the movement of a moving object inside the vehicle towards the driver's seat by the internal detection unit 122, it will send a second notification to the outside of the vehicle. Also, for example, if the notification unit 124 does not detect an approaching motion of a moving object to the vehicle by the external detection unit 121, but detects the operation of an in-vehicle device by the internal detection unit 122, it will send a second notification to the outside of the vehicle.

[0037] [External vehicle detection processing] Next, the external detection process performed by the monitoring device 100 will be explained using Figures 3 and 4. The external detection unit 121 of the monitoring device 100 detects moving objects outside the vehicle using motion sensors such as distance sensors (microwave sensors, LiDAR, etc.). At this time, as shown in Figure 3, the external detection unit 121 can perform a risk analysis of approaching moving objects using information on position (distance risk) and direction (direction risk). For example, the external detection unit 121 may perform a risk analysis using a table that combines position and direction, and detect the approach of a moving object to the vehicle when the risk point exceeds a threshold. Note that, as shown in Figure 3, the external detection performed by the monitoring device 100 targets not only moving objects located to the sides of the vehicle, but also moving objects located around the vehicle, including in the front and rear directions.

[0038] For example, in Figure 3, if the object moves from a distance where it can be touched after a short movement to the direction of the car (center) and then to a distance where it can be easily touched, the external detection unit 121 analyzes that the risk point is 6 because the object is getting closer to the car and moving towards the center of the car.

[0039] Furthermore, for example, in Figure 3, if the object moves from a distance that can be easily touched to a direction parallel to the car and then back to a distance that can be easily touched, the external detection unit 121 analyzes that the risk point is 4 because although the distance to the car is close, the direction of movement is parallel to the car. Also, for example, in Figure 3, if the object moves from a distance that can be touched after a short movement to a direction opposite to the car and then to a distance where it cannot be touched, the external detection unit 121 analyzes that the risk point is 1 because the distance to the car is far and the direction of movement is opposite to the car.

[0040] The external detection unit 121 may calculate risk points using distance risk and directional risk through various calculations such as summing or multiplying. The external detection unit 121 may also perform risk analysis at predetermined intervals and add risk points. Furthermore, the external detection unit 121 may estimate the behavior of a moving object from the fluctuations in risk points and detect the approach of a moving object to the vehicle if it is estimated that a predetermined behavior has occurred.

[0041] In this way, the monitoring device 100 can detect moving objects outside the vehicle by performing a risk analysis using position and direction, and can then detect moving objects after evaluating them according to their movement, such as passing by, peeking in, or entering the vehicle. In other words, the monitoring device 100 can prevent false detections and reduce unnecessary alarms and notifications.

[0042] Furthermore, as shown in Figure 4, the external detection unit 121 uses location information to distinguish between movement and stay. For example, the external detection unit 121 distinguishes between movement and stay based on whether the distance traveled during a predetermined period is below a threshold. For example, the external detection unit 121 determines that the vehicle is staying if the distance traveled during X seconds is less than the radius R.

[0043] [Notification Processing] Next, using Figure 5, we will explain the notification made by the monitoring device 100 to the outside of the vehicle. If the notification unit 124 detects a moving object inside the vehicle using the in-vehicle detection unit 122, without detecting a person approaching the vehicle using the external detection unit 121, it will send a second notification to the outside of the vehicle. At this time, as shown in Figure 5, the notification unit 124 may notify the user terminal of the detected information, the action taken by the monitoring device 100, and an image. For example, the notification unit 124 will notify the user terminal of the message "A moving object was detected inside the vehicle without detecting an abnormality. It was determined that there is a person waiting, and the system has been turned OFF," the date and time information "2022 / 08 / 01 14:35," the detection type "Person waiting," and the target image.

[0044] 〔flowchart〕 Next, the processing performed by the monitoring device 100 with the above configuration will be explained with reference to the flowchart in Figure 6. The flowchart in Figure 6 is mainly executed by the control unit 120. Furthermore, this flowchart can be configured as a monitoring program to be executed by the CPU of the control unit 120. Note that steps S101 to S106 below can be executed in a different order. Also, some of the processes in steps S101 to S106 below may be omitted.

[0045] First, the notification unit 124 determines whether or not a moving object outside the vehicle has been detected by the external detection unit 121 (step 101). If the notification unit 124 determines that a moving object outside the vehicle has been detected by the external detection unit 121 (step S101 "YES"), the notification unit 124 then determines whether or not a moving object inside the vehicle has been detected by the internal detection unit 122 (step S102).

[0046] Here, if the notification unit 124 determines that a moving object has been detected inside the vehicle by the in-vehicle detection unit 122 (step S102 "YES"), the notification unit 124 notifies the outside of the vehicle of the first notification and the second notification (step S103).

[0047] On the other hand, returning to step S102, if the in-vehicle detection unit 122 determines that no moving object has been detected inside the vehicle (step S102 "NO"), the notification unit 124 sends a first notification to the outside of the vehicle (step S104).

[0048] On the other hand, returning to step S101, if the notification unit 124 determines that no moving object has been detected outside the vehicle by the external detection unit 121 (step S101 "NO"), the notification unit 124 then determines whether or not a moving object has been detected inside the vehicle by the internal detection unit 122 (step S105).

[0049] Here, if the notification unit 124 determines that a moving object has been detected inside the vehicle by the in-vehicle detection unit 122 (step S105 "YES"), the notification unit 124 sends a second notification to the outside of the vehicle (step S106).

[0050] On the other hand, returning to step S105, if the in-vehicle detection unit 122 determines that no moving object has been detected inside the vehicle (step S105 "NO"), the notification unit 124 does not issue either the first or second notification.

[0051] 〔effect〕 The monitoring device 100 according to this embodiment includes an external detection unit 121 for detecting moving objects outside the vehicle, an internal detection unit 122 for detecting moving objects inside the vehicle, and a notification unit 124 that, when the external detection unit 121 detects the approach of a moving object to the vehicle and the internal detection unit 122 detects a moving object inside the vehicle, notifies the outside of the vehicle of a first notification and a second notification.

[0052] As a result, the monitoring device 100 can use the detection information of moving objects outside the vehicle and the detection information of moving objects inside the vehicle to send multiple types of notifications to the outside of the vehicle, thereby providing appropriate notifications according to the situation inside and outside the vehicle.

[0053] Furthermore, in the monitoring device 100 according to the embodiment, the external detection unit 121 uses position and direction information to detect when a moving object approaches the vehicle.

[0054] As a result, the monitoring device 100 can detect moving objects outside the vehicle using position and direction information, thereby preventing false detections of moving objects outside the vehicle, and can provide appropriate notifications according to the situation inside and outside the vehicle.

[0055] Furthermore, in the monitoring device 100 according to this embodiment, the notification unit 124 issues an audible alarm as a first notification and notifies the user terminal as a second notification.

[0056] As a result, the monitoring device 100 can issue an alarm for high-risk external situations and notify the user terminal for internal situations that require notification, thereby providing appropriate notifications according to the situation inside and outside the vehicle.

[0057] Furthermore, in the monitoring device 100 according to this embodiment, if the external detection unit 121 does not detect the approach of a moving object to the vehicle, and the internal detection unit 122 detects a predetermined state inside the vehicle, the notification unit 124 will send a second notification to the outside of the vehicle.

[0058] As a result, the monitoring device 100 does not issue an alarm when an alarm is unnecessary, and issues a notification when a predetermined condition is detected inside the vehicle, thereby enabling it to provide appropriate notifications according to the conditions inside and outside the vehicle.

[0059] Furthermore, in the monitoring device 100 according to this embodiment, if the external detection unit 121 does not detect an approaching moving object to the vehicle, but the internal detection unit 122 detects a moving object inside the vehicle, the notification unit 124 will send a second notification to the outside of the vehicle.

[0060] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and issues a notification when it detects movement inside the vehicle, thereby providing appropriate notifications according to the situation inside and outside the vehicle.

[0061] Furthermore, the monitoring device 100 according to the embodiment further includes an acquisition unit 123 for acquiring the temperature inside the vehicle, and the notification unit 124 notifies the outside of the vehicle if the outside detection unit 121 does not detect the approach of a moving object to the vehicle, the inside detection unit 122 detects a moving object inside the vehicle, and the temperature inside the vehicle acquired by the acquisition unit 123 exceeds a threshold.

[0062] As a result, the monitoring device 100 does not issue an alarm when an alarm is unnecessary, detects movement inside the vehicle, and issues a notification when the temperature inside the vehicle exceeds a threshold, thereby preventing accidents involving people being left unattended inside the vehicle and providing appropriate notifications according to the conditions inside and outside the vehicle.

[0063] Furthermore, the monitoring device 100 according to the embodiment further includes an acquisition unit 123 for acquiring audio from inside the vehicle, and the notification unit 124 notifies an external party outside the vehicle if the external detection unit 121 does not detect the approach of a moving object to the vehicle and the volume of the audio from inside the vehicle acquired by the acquisition unit 123 exceeds a threshold.

[0064] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and issues a notification when the volume of the audio inside the vehicle exceeds a threshold, thereby preventing accidents involving people being left unattended inside the vehicle and enabling it to provide appropriate notifications according to the situation inside and outside the vehicle.

[0065] Furthermore, in the monitoring device 100 according to this embodiment, if the external detection unit 121 does not detect the approach of a moving object to the vehicle, but the internal detection unit 122 detects the movement of a moving object inside the vehicle towards the driver's seat, the notification unit 124 will send a second notification to the outside of the vehicle.

[0066] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and notifies when a moving object inside the vehicle moves to the driver's seat, thereby encouraging vigilance against accidental errors by waiting personnel, etc., and enabling it to provide appropriate notifications according to the situation inside and outside the vehicle.

[0067] Furthermore, in the monitoring device 100 according to this embodiment, if the external detection unit 121 does not detect the approach of a moving object to the vehicle, and the internal detection unit 122 detects the operation of an in-vehicle device, the notification unit 124 will send a second notification to the outside of the vehicle.

[0068] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and issues a notification when it detects operation of an in-vehicle device, thereby preventing unauthorized operation of vehicle devices by standby personnel, etc., and can provide appropriate notifications according to the situation inside and outside the vehicle.

[0069] [Hardware configuration] Furthermore, the monitoring device 100 according to the above-described embodiment is implemented by a computer 1000 having the configuration shown in Figure 7. Figure 7 is a hardware configuration diagram showing an example of a computer that implements the functions of the monitoring device 100. The computer 1000 has a CPU 1100, RAM 1200, ROM 1300, HDD 1400, communication interface (I / F) 1500, input / output interface (I / F) 1600, and media interface (I / F) 1700.

[0070] The CPU 1100 operates based on programs stored in the ROM 1300 or HDD 1400, controlling various components. The ROM 1300 stores boot programs executed by the CPU 1100 when the computer 1000 starts up, as well as programs that depend on the computer 1000's hardware.

[0071] The HDD 1400 stores programs executed by the CPU 1100 and data used by such programs. The communication interface 1500 receives data from other devices via a predetermined communication network and sends it to the CPU 1100, and transmits data generated by the CPU 1100 to other devices via the predetermined communication network.

[0072] The CPU 1100 controls output devices such as displays and printers, and input devices such as keyboards and mice, via the input / output interface 1600. The CPU 1100 acquires data from input devices via the input / output interface 1600. The CPU 1100 also outputs the generated data to output devices via the input / output interface 1600.

[0073] The media interface 1700 reads a program or data stored in the recording medium 1800 and provides it to the CPU 1100 via the RAM 1200. The CPU 1100 loads the program from the recording medium 1800 onto the RAM 1200 via the media interface 1700 and executes the loaded program. The recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or PD (Phase Change Rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0074] For example, when the computer 1000 functions as a monitoring device 100 according to the embodiment, the CPU 1100 of the computer 1000 realizes the functions of the control unit 120 by executing a program loaded on the RAM 1200. The CPU 1100 of the computer 1000 reads and executes these programs from the recording medium 1800, but as another example, these programs may be obtained from other devices via a predetermined communication network.

That is, those skilled in the art can carry out various modifications in accordance with conventionally known knowledge, without departing from the core of the present invention. As long as such modifications still include the monitoring device of the present invention, they are of course included within the scope of the present invention. [Explanation of Symbols]
