JP 2020-149433 Publication

One of the objectives is to provide a technology different from conventional vehicle monitoring. For example, one of the purposes of conventional parking monitoring is to prevent mischief, theft, etc. to the vehicle. Problems such as preventing accidents such as heat stroke cannot be solved.

The above-mentioned problems are described as being independent from each other, and the present invention does not necessarily need to be able to solve all of the described problems. The purpose of the invention of the present application is not limited to this, and we intend to acquire rights through divisional applications, amendments, etc. for structures that aim to obtain effects from the parts of the structure disclosed in this specification, drawings, etc. . For example, the present specification discloses a problem in which the phrase ``can be done'' is replaced with ``the problem is.'' Each of the problems is described as independent, and we intend to obtain rights for the structure to solve these problems independently through divisional applications, amendments, etc. Even if the problem is implicitly understood from the description of the specification, the present applicant has the intention of claiming a part of the structure described in the specification in an amendment or divisional application. Also, issues that combine these independent issues are also disclosed.

The following is an example of means for solving problems related to conventional vehicle monitoring.

(1) It is preferable that the system is provided with a detection function for detecting the state of the interior of a vehicle that is parked and/or stopped, and an output function that outputs predetermined information based on the detection result. In this way, predetermined information based on the condition inside the vehicle is output, so that the condition inside the vehicle can be known. The output function may be, for example, one in which the system directly reports or sends information through communication to the outside. The predetermined information may be, for example, the detection result itself, information used during detection, or other information.

(2) The state inside the vehicle interior detected by the detection function may be whether or not there is a person in the rear seat of the vehicle. In this way, for example, if there is a person in the back seat, a predetermined output is generated, so the driver can know that there is a person in the back seat, and can prevent, for example, from leaving a child behind. It can be prevented. Further, even if children or the like are left in the car, it is possible to confirm that they are inside the car, so that accidents can be prevented by allowing the child to return to the car quickly, for example.

(3) The state inside the vehicle interior detected by the detection function may be whether or not a person is present in a child seat installed in the vehicle. In this way, for example, if there is a child in the child seat, a predetermined output will be made, so the driver will be able to know that there is a child in the child seat, and this will prevent the child from being left behind, for example. be able to. Further, even if children or the like are left in the car, it is possible to confirm that they are inside the car, so that accidents can be prevented by allowing the child to return to the car quickly, for example.

(4) It is preferable to include a function of performing image analysis on an image acquired from a means for photographing the rear seat side of the vehicle or the child seat to determine whether there is a person in the image. This is good because the presence of a person can be reliably known through image analysis. Image analysis may be performed by an image processing circuit installed in the vehicle (on the edge side) because the amount of data to be communicated after analysis can be reduced.

(5) When the image analysis is performed and the presence of a person is detected in the image, the output function may send the detection result without sending the image. In this way, when a person is detected, the detection result is sent, but image data is not sent, so notification can be made quickly and the amount of communication data can be reduced.

(6) The state inside the vehicle interior detected by the detection function may be the presence or absence of an object moving within the vehicle interior. Since the object moving inside the vehicle is, for example, a person or an animal, the driver or the like can be aware of the presence of such an object and can prevent the object from being left behind in the vehicle.

(7) The detection function shall acquire sounds audible within the vehicle interior and detect a dangerous condition from the acquired sounds, and the output function shall be configured to output a signal to the outside when the dangerous condition is detected. It would be best to let them know by communicating. In this way, for example, a driver or the like who is away from the vehicle can know that the vehicle is in a dangerous situation. This allows the driver and the like to quickly return to the vehicle. Sounds that can be heard inside the vehicle include, for example, sounds that occur inside the vehicle such as the voice of a person remaining in the vehicle, sounds that are generated from the vehicle, and sounds that are generated around the vehicle that can be heard inside the vehicle. .

(8) The detection function may detect a dangerous condition based on the temperature inside the vehicle, and the output function may notify the outside by communicating when the dangerous condition is detected. . In this way, for example, a driver or the like who is away from the vehicle can know that the vehicle is in a dangerous situation. This allows the driver and the like to quickly return to the vehicle.

(9) The detection function shall detect a dangerous condition based on the temperature inside the vehicle,
The output function may not communicate the predetermined information to the outside if the dangerous condition is not detected. In this way, for example, if the driver intentionally leaves a child, etc. in the vehicle, the notification will not be sent if the temperature inside the vehicle is not dangerous, eliminating the hassle of receiving unnecessary notifications. , you will no longer be notified. Therefore, for example, necessary information can be notified when necessary.

(10) The predetermined information may be the detection result. In this way, the driver or the like can know the condition inside the vehicle based on the detection results.

(11) Preferably, the detection function detects the state inside the vehicle interior based on the output of a seating sensor provided in a child seat installed in the vehicle. In this way, the presence or absence of a child can be reliably detected, and appropriate output can be performed based on this.

(12) It is preferable that the vehicle includes a means for detecting the movement of the driver, and that the output function outputs a warning when the driver gets out of the vehicle while a person is present in the child seat. In this way, the driver can confirm that there is a person (for example, a child) in the child seat when getting off the car, and can prevent the child seat from being left behind unintentionally. By knowing this when you get off the train, you can return quickly and prevent accidents from occurring.

(13) It is preferable to provide a function to prevent the doors of the vehicle from being locked when a person is present in the child seat. In this way, it is possible to prevent a situation in which a child or the like is left trapped inside the vehicle.

(14) When a person is present in the child seat and the door of the vehicle is locked, a function that notifies the person of the presence of the person and prevents the vehicle from being locked; If the locking operation is performed after the notification is made, the device may be locked. In this way, the presence of a person in the child seat will be notified when the child seat is locked, so it is possible to prevent children from unintentionally leaving the child seat in the vehicle. In some cases, the vehicle doors can be locked.

(15) The detection function is for detecting the temperature inside the vehicle interior, and the output function is for transmitting the temperature to a predetermined communication destination when the temperature inside the vehicle interior satisfies a condition. It is preferable that the vehicle be provided with a function of remotely controlling the vehicle from a terminal of a predetermined communication destination to change the state of the interior of the vehicle.

In this way, by setting the conditions appropriately, it is possible to check whether the inside of the vehicle is at a high temperature that may cause heat stroke, etc., or whether it is low temperature that may cause hypothermia, etc. You can also learn about situations that are just one step away from becoming dangerous. Then, the driver can, for example, return to the vehicle and quickly take measures to avoid the dangerous situation. Furthermore, the state of the interior of the vehicle can be changed by remote control of the vehicle from the communication destination terminal, which is advantageous because, for example, the interior of the vehicle can be prevented from becoming in a dangerous state more quickly.

(16) The detection function preferably has a function of photographing the interior of the vehicle, and the output function preferably transmits the photographed image to a predetermined communication destination. In this way, a user such as a driver who is far away from the vehicle can know the condition inside the vehicle, and can appropriately judge whether or not it is necessary to return to the vehicle and take action.

(17) Each of the functions described above may be configured by a drive recorder.

(18) A smart band is provided that is attached to a child's leg or arm to detect the child's biological information, and the condition inside the vehicle detected by the detection function is the biological information of the child in the vehicle; The output function may be realized by a communication function provided in the smart band to send the ecological information. In this way, a user such as a driver who is away from the vehicle can know the condition of the child inside the vehicle, and can appropriately judge whether or not it is necessary to return to the vehicle and take action.

(19) It is preferable to provide a program for causing a computer to implement the functions of the system in any one of (1) to (18).

The system described above may be composed of one device or a plurality of devices.

The inventions (1) to (18) described above can be combined arbitrarily. For example, it may be possible to add at least a part of the structure of at least one invention described in (2) to all or part of the structure of the invention shown in (1). In particular, it is preferable to create an invention in which at least a part of the structure of at least one invention after (2) is added to the invention shown in (1). The applicant of this application has the intention of acquiring patent rights, design rights, etc., by filing amendments, divisional applications, conversion applications to design registration applications, etc., even for products containing these structures.

According to the present invention, the driver and the like can check the state inside the vehicle interior. Additionally, depending on the timing of the output, the driver can check when getting off the vehicle or after leaving the vehicle. The driver can then take measures to avoid a dangerous situation.

The effects of the invention of the present application are not limited to these, but the effects obtained from the parts of the structure disclosed in the specification, drawings, etc. are also disclosed, and the rights to the structure that achieves the effects have also been acquired through divisional applications, amendments, etc. have the intention to For example, in this specification, a portion where it is written as "can be done" is a statement that clearly indicates the effect to be achieved, and there are parts that show an effect even if there is no mention of "can be done".

Embodiments of the present invention will be described below with reference to the drawings. These drawings are used to explain technical features that can be adopted by the present invention. The configuration, shape, etc. of the device described are merely illustrative examples, and the present invention is not to be construed as being limited thereto. , various changes, modifications, and improvements may be made. In the following explanation, labeling using numerical values such as first and second is for identifying each element, and is not for determining the number of elements.

[How the invention of the present application was conceived]
When driving a vehicle with a child under the age of 6, it is compulsory to use a child seat. Furthermore, even for children over 6 years old, it is recommended that a child seat be used according to the child's growth until the child reaches 140 cm, which is the height at which a vehicle seat belt can be worn. There is a type of child seat that is installed in the back seat of a vehicle. For example, the occurrence of accidents such as heat stroke among children who are trapped inside a vehicle and who are left behind in a car while seated in a child seat has become a social problem. Factors that can cause such accidents include, for example, when the driver forgets that there is a child sitting in a child seat and gets out of the car, or when the driver is aware of the child's presence but when he or she sees the child when getting off the car. If you are sleeping, you may feel bad for waking him up and get off the train thinking, ``It's probably time to go shopping, so it's okay,'' or ``I'll be right back, so it's okay.'' It will be done. In addition, in consideration of children remaining in the vehicle, if you leave the vehicle with the air conditioner running while the engine is running, the air conditioner may stop due to the engine turning off for some reason, for example, and if this occurs, The temperature of the vehicle may rise, putting children inside the vehicle at risk of heat stroke. Regardless of the presence or absence of a child seat, a similar situation can occur if, for example, the driver leaves the vehicle with a child in the vehicle, expecting to return soon, and it takes longer than expected to return to the vehicle. There is. Furthermore, accidents that occur when a child is left unattended in a parked car are not limited to heat stroke caused by the rise in temperature inside the car as mentioned above; for example, accidents caused by a drop in the temperature inside the car in winter, etc. There is also hypothermia. The following embodiment is an example of an embodiment for solving such a problem.

[Basic configuration of an embodiment of the system]
1 and 2 show a preferred embodiment of the system. The system of the present embodiment includes a drive recorder 10, which is an aspect of electronic equipment or in-vehicle equipment, and a power supply device 30 that supplies power to the drive recorder 10. By receiving power from the power supply device 30, the drive recorder 10 can operate for a predetermined period of time even when the vehicle is parked with the engine turned off. Further, the drive recorder 10 alone constitutes one embodiment of the system of the present application.

In this embodiment, the drive recorder 10 is a device that is installed later on the vehicle 1. The drive recorder 10 is mounted, for example, at a predetermined position above the windshield 2 of the vehicle 1 or at an appropriate position, such as on the dashboard. In the illustrated example, a child seat 4 is installed in a rear seat 3 of a vehicle 1. The child seat 4 is, for example, an auxiliary device for infants, and includes, for example, a child seat for infants (also referred to as a baby seat), a child seat for infants, a child seat for school children (also referred to as a junior seat), and the like.

The power supply device 30 is a device that is interposed between the vehicle and the drive recorder 10 and supplies power to the drive recorder 10. The power supply device 30 is configured from a separate housing from the drive recorder 10. The power supply device 30 includes a charge/discharge control section 30a, a DC-DC converter 30b, a CPU 30c, an internal battery 30d, and the like. The charge/discharge control unit 30a controls charging of the internal battery 30d and power supply to the drive recorder 10. The internal battery 30d is a secondary battery, and is realized by, for example, a nickel metal hydride rechargeable battery. The DC-DC converter 30b converts the 12V or 24V voltage supplied from the vehicle's battery into a 5V voltage via the charge/discharge control unit 30a and outputs the voltage. The CPU 30c uses a memory (for example, a RAM) not shown as a work area, and controls each part of the power supply device 30, such as the charge/discharge control section 30a. Further, the CPU 30c communicates with the drive recorder 10 connected via the cable 5. The cable 5 includes a power line and a communication line.

The charge/discharge control section 30a receives power from the internal battery 30d. The charge/discharge control unit 30a controls the power supply path so that power is supplied from the vehicle battery to the internal battery 30d and the DC-DC converter 30b while power is being supplied from the vehicle battery. As a result, the internal battery 30d is charged, and the DC-DC converter 30b supplies voltage-converted power to the drive recorder 10. The charge/discharge control unit 30a determines whether the ACC of the vehicle is ON or OFF and switches whether to charge or discharge the internal battery 30d. When the charge/discharge control unit 30a determines that the ACC is ON, it controls the power to be supplied from the vehicle battery to the internal battery 30d and the DC-DC converter 30b. When charging/discharging control section 30a determines that ACC is OFF, it controls to discharge internal battery 30d and to supply power from internal battery 30d to DC-DC converter 30b.

As described above, the power supply device 30 receives power from the vehicle battery and outputs power to the drive recorder 10 while the ACC is ON. When the power supply from the vehicle battery is cut off, power is output to the drive recorder 10 using the internal battery 30d for a specified time after the power supply is cut off. When the specified time has elapsed, the power output is turned off. When the supply of power from the vehicle battery is resumed, the vehicle battery is used to output power to the drive recorder 10 again.

Thereby, the drive recorder 10 can continue to operate for a specified period of time after the ACC is turned off and power supply from the vehicle battery is cut off. The prescribed time may be set by serial communication from the drive recorder 10, for example. When the drive recorder 10 receives the battery switching signal from the power supply device 30, it transmits a signal instructing a specified time. It is preferable that the CPU 30c sets the prescribed time setting value included in the received signal instructing the prescribed time as the prescribed time.

Further, it is preferable that the power supply device 30 is provided with a dip switch or other operation section to have a function of setting a specified time. In this way, for example, power can be supplied even to a drive recorder that does not have a communication function until a specified time has elapsed after the supply from the vehicle's battery is cut off.

When the power supply from the vehicle battery is cut off, the power supply device 30 switches the power supply source to the internal battery 30d and supplies power to the drive recorder 10. Since the drive recorder 10 continues to be supplied with power before and after switching, the drive recorder 10 cannot determine whether the power supply source is the vehicle battery or the internal battery 30d. Therefore, when the CPU 30c switches the power supply source to the internal battery 30d, it transmits a battery switching signal to the drive recorder 10. If the ACC is turned ON after the power supply device 30 turns off the output after the specified time has elapsed, the drive recorder 10 restarts the stopped power supply, so it can be determined that the ACC has been turned ON. . On the other hand, if the ACC is turned on within the specified time, the drive recorder 10 continues to be powered, so it is not possible to determine whether the power source is the vehicle's battery or the internal battery 30d. Therefore, if the ACC is turned on within the specified time, the CPU 30c transmits a vehicle switching signal to notify that the power supply source has been switched to the vehicle battery. Thereby, the drive recorder 10 can recognize that the ACC has been turned on and the power supply source has been switched to the vehicle battery. The drive recorder 10 may switch its operating mode in response to input of the battery switching signal and the vehicle switching signal.

The drive recorder 10 has a function of capturing an image of a predetermined area with a camera that is a photographing device, a function of generating the captured image and other data, a function of outputting the generated data, and the like. Data output includes output for recording the data in a storage area, output (that is, transmission) of the data through communication, output to external equipment via a data output terminal, and the like. Further, the predetermined area photographed by the drive recorder 10 of the present embodiment may be, for example, a front area of the vehicle and an indoor area including the child seat 4 in the vehicle interior. In this way, the camera for photographing the front area and the indoor area may be equipped with, for example, multiple cameras, with the field of view of each camera facing the direction of each area, or, for example, a 360° camera or a camera with a larger angle of view. It is best to use a camera with a single camera to take pictures of the front and inside of the vehicle.In particular, it is good to use a plurality of cameras because the area including the child seat can be taken with high accuracy.

The drive recorder 10 includes a camera 11, a microphone 12, an abnormality detection sensor 13, a GPS module 14, an operation section 15, a control section 16, a temporary memory 17, a monitor 18, a speaker 19, a memory card slot 20, a microwave sensor 22, a temperature It includes a humidity sensor 23, a communication section 24, and the like. One or more cameras 11 are provided, and the cameras 11 photograph a predetermined area such as the front of the vehicle and a predetermined area inside the vehicle interior. The microphone 12 collects surrounding sounds, for example. The microphone 12 collects, for example, the voices of people inside the car and other sounds occurring inside the car, as well as the impact sound when an object collides with the car. The abnormality detection sensor 13 is, for example, an acceleration sensor or a 6-axis sensor (integrated with 3-axis acceleration and 3-axis angular velocity), and detects vehicle conditions such as an impact applied to the vehicle, vehicle acceleration, and inclination.

The control unit 16 estimates that an accident (collision) has occurred when the detected value of the abnormality detection sensor 13 exceeds a threshold value or shows a predetermined temporal change indicating, for example, that an impact has occurred. In addition to the occurrence of an accident, the control unit 16 may also be used to detect driving situations such as sudden braking, sudden steering, sudden starting, and sudden braking, and to record the history thereof.

The GPS module 14 receives GPS signals based on positioning. GPS is an example of the Global Navigation Satellite System (GNSS), which is a satellite positioning system. Positioning using GNSS is generally used as GPS positioning. A GPS signal is a signal that can be received from a GPS satellite. The GPS module 14 obtains location information (longitude, latitude) of the current location from the received GPS signal using a unique algorithm. For example, the control unit 16 may acquire the position information output from the GPS module 14 periodically (for example, every second).

The operation unit 15 is a button that gives various instructions to the control unit 16, and has a function of giving an instruction to start recording, for example. When the operation unit 15 is pressed, the control unit 16 may perform event recording to start recording the video captured by the camera 11 and the sound collected by the microphone 12. Further, the operation unit 15 preferably has a function of giving an instruction to stop recording. The recording start instruction and the recording stop instruction may be given, for example, by different buttons for giving the respective instructions, but it is preferable that they be given by different operations on the same button. This is good because the number of buttons installed can be reduced and the drive recorder 10 can be made smaller.

The temporary storage memory 17 is, for example, a RAM that temporarily stores video data captured by the camera 11, for example. The control unit 16 constantly stores at least video data captured over a certain period of time from the present. Since storage capacity is limited, the control unit 16 deletes old video data and the like based on a certain standard. The certain criteria may be, for example, video data stored a certain period of time or more ago, or the case where the memory capacity to be stored exceeds a certain value. In this embodiment, the temporary storage memory 17 may be configured by, for example, a ring buffer.

The monitor 18 is a display unit that displays images. The control unit 16 displays, for example, video data captured by the camera 11 on the monitor 18 in real time. The speaker 19 outputs sound. The control unit 16 outputs a predetermined sound from the speaker 19 at the time of predetermined recording, alarm, operation, and the like. The control unit 16 uses the speaker 19 to notify, for example, operation sounds from the operation unit 15 and various messages (guidance, warning, etc.).

For example, a micro SD card 21 can be inserted into and removed from the memory card slot 20. The control unit 16 reads and writes data to and from the micro SD card 21 when the micro SD card 21 is attached. The micro SD card 21 is a storage medium on which data such as images and position information are recorded by the drive recorder 10. The micro SD card 21 is an external storage device that can be inserted into and removed from the memory card slot 20, but instead of or in combination with it, the internal storage device of the drive recorder 10 (for example, a hard disk or EEPROM) or other storage device can be used. It's okay to be hit. However, if the drive recorder 10 is allowed to access a system that can record data without using an environment that can be accessed by an unspecified number of people (for example, a cloud computing environment), the data stored in the storage means desirable in terms of protecting the environment.

The microwave sensor 22 detects, for example, the movement of an object inside the vehicle, and is preferably configured to detect the movement of an object (for example, a person) on the rear seat 3 or the child seat 4, for example. The temperature and humidity sensor 23 detects the temperature and humidity inside the vehicle. The communication unit 24 may use, for example, an LTE-M module capable of LTE (Long Term Evolution) communication.

The control unit 16 is a microcomputer equipped with a CPU, ROM, RAM, non-volatile memory, I/O, etc., and includes the various input devices described above (camera 11, microphone 12, abnormality detection sensor 13, GPS module 14, operation unit 15). , temporary memory 17, memory card slot 20, microwave sensor 22, temperature/humidity sensor 23, etc.), and output devices (temporary memory 17, monitor 18, speaker 19, Predetermined information is output using the memory card slot 20, communication unit 24, etc.). The functions of the drive recorder 10 are realized by being stored in the EEPROM of the control unit 16 as a program executed by the computer included in the control unit 16, and executed by the computer included in the control unit 16. The functions realized by the computer by the programs included in the control unit 16 include functions for performing various controls in the drive recorder 10. The control unit 16 has, for example, a function of recording data such as video and position information, a function of outputting data, a function of displaying an image (video), and the like.

The control unit 16 is a circuit for realizing the basic functions of the drive recorder 10, and stores video data captured by the camera 11 as a video file in the temporary storage memory 17, and receives detection signals from the abnormality detection sensor 13, etc. Based on the press of the operation unit 15, the above-mentioned imaged video file is stored in the nonvolatile memory. In this embodiment, a micro SD card 21 inserted into the memory card slot 20 is used as the nonvolatile memory. By removing this micro SD card 21 and inserting it into a memory card reader or the like connected to a personal computer, the data can be imported into the personal computer and the video file can be played using a viewer installed on the personal computer. Furthermore, the recorded images and the like are not limited to being taken out by attaching and detaching the micro SD card 21 as described above, but may be transferred by data transmission using wired communication or wireless communication. Further, in order to perform wired communication, the main body of the drive recorder 10 may be provided with a connector, USB, etc. for connecting a communication cable.

The function of recording this video data (recording function) will be explained in more detail. For example, when the engine is started and the ACC is ON, the camera 11 constantly captures images of the surroundings of the own vehicle. Then, the control unit 16 stores, for example, video data captured by the camera 11 in a temporary storage memory 17 such as a ring buffer. The video stored in this temporary storage memory 17 is sequentially updated to the latest one, and past video data is retained for a set amount of time.

For example, when the output value of the abnormality detection sensor 13 exceeds a threshold value or shows a predetermined temporal change due to an impact caused by an accident, sudden braking, or sudden steering, the control unit 16 detects an impact occurring before the impact is detected. The video data for a certain period of time is read out from the temporary storage memory 17 and stored in a non-volatile memory, for example, a micro SD card 21, and after the threshold is exceeded, the video captured by the camera 11 thereafter is stored in the micro SD card 21. Recording is performed directly or via the temporary storage memory 17. As a result, images for a predetermined period of time before and after the impact are stored in the micro SD card 21, which is a non-volatile memory. At this time, the control unit 16 also records the surrounding sounds collected by the microphone 12 in association with the video data. The control unit 16 also temporarily stores this recording in the temporary storage memory 17, and when storing the video data in the micro SD card 21, also stores the recorded audio data in the micro SD card 21.

The storage of data in the micro SD card 21 in the drive recorder 10 is not limited to being triggered by the detection signal of the abnormality detection sensor 13 as described above. For example, the control unit 16 may have a function that is activated when the operation unit 15 is pressed. In this way, when a situation that the user wants to record occurs, the video can be recorded.

Furthermore, recording to the micro SD card 21 is not limited to the event recording mode, which is performed when a recording start condition is met, such as when an accident occurs based on the output of the abnormality detection sensor 13 or when the operation unit 15 is pressed. For example, it is preferable to provide a constant recording mode in which the drive recorder 10 records data on the micro SD card 21 from when the power is turned on until it is turned off. The constant recording mode is a mode in which constant recording is performed, which is an example of recording other than event recording. When the constant recording mode is provided, the control unit 16 records the video data output from the camera 11 and the sound data output from the microphone 12 directly to the micro SD card 21 instead of the temporary storage memory 17. It is better to make it . By directly recording to the micro SD card 21 in this way, the process of writing once to the temporary storage memory 17 is unnecessary.

In addition, when writing video data, etc. directly to the micro SD card 21, and when having a constant recording mode and an event recording mode, the control unit 16 controls the recording start condition when the event recording start condition is satisfied. It is preferable to use data that is constantly recorded as the data for the past sections. In event recording, the control unit 16 may record the event recording as a separate file from the constant recording file, for example. The event recording mode is a mode for performing event recording. Event recording is recording that is performed in response to the occurrence of a predetermined event (an example of an event). Event recording is performed when a predetermined event occurs even if the user does not explicitly instruct to start recording.

While the vehicle is parked with the engine stopped (ACC turned OFF), it is preferable to operate in parking monitoring mode and record video data etc. captured by the camera 11 in accordance with set operating conditions on the micro SD card 21. Recording in parking surveillance mode is the same as when ACC is ON, for example, continuous recording that always records images taken during a predetermined recording time (for example, 30 minutes), or when an abnormality is detected by the abnormality detection sensor 13. It is preferable to include an event recording function that continuously records video data for a predetermined period of time. Event recording can be performed, for example, by ``detecting the approach of a person or vehicle,'' ``detecting an impact above a certain level,'' ``detecting a vehicle inclination above a certain level (e.g., jacking up),'' or ``detecting the opening of a vehicle door.'' Performed when event conditions such as "detection" are met. The abnormality detection sensor 13 includes one or more sensors for performing such detection.

[Information and avoidance function of dangerous conditions inside the vehicle]
The drive recorder 10 has a function of notifying the driver etc. and performing predetermined danger avoidance processing when a dangerous situation occurs inside the vehicle while the vehicle is stopped or parked. . Dangerous conditions include, for example, children being left behind in the car, and children remaining in the car being at risk of life-threatening conditions such as heat stroke. When the drive recorder 10 receives a battery switching signal from the power supply device 30 (ACC is OFF), the drive recorder 10 switches to a monitoring mode for monitoring the presence or absence of a dangerous condition in the vehicle interior, and the control unit 16 performs the following processing.

*Image-based Detection The control unit 16 has an image analysis function that analyzes whether a person is included in the image to be processed. When switching to the monitoring mode, an image taken by the camera 11 that photographs the area including the child seat 4 is acquired, image analysis is performed, and the presence or absence of a person is determined. When a person is detected in the image, the control unit 16 uses the communication unit 24 to transmit predetermined information to the registered destination. The predetermined information may be a presence notification indicating that a child is present, an acquired image, temperature information and humidity information in the vehicle interior acquired from the temperature/humidity sensor 23, position information acquired from the GPS module 14, etc. It is good to send only the recognition results without sending images, as this reduces the amount of communication and allows prompt notification. Further, the image analysis may be performed by software processing, but for example, it is preferable to use a chip having an image recognition function and a function of sending only the recognition result to the server without sending the image.

The registered destination may be, for example, the server 32 such as a cloud server or the driver's smartphone 33. The server 32 associates and stores the information of the drive recorder 10 and the user's destination, and when predetermined information is sent from the drive recorder 10, the server 32 stores the received information and stores all or the acquired information. Send some to the associated user's destination. As a result, for example, if a child is sitting in the child seat 4 when the ACC is turned off to park or stop, the driver's smartphone 33 or the like is notified directly or via the server 32. As a result, the driver is made aware of the presence of the child again, and the risk of the driver forgetting the presence of the child sitting in the child seat 4 and getting out of the vehicle can be suppressed as much as possible. Also, even if you leave your child in the car for some reason, if you are alerted to the child's presence, you can take measures such as restarting the engine, turning on the air conditioner, or returning to the car as soon as possible. This makes it possible to prevent children remaining in the vehicle from suffering from heatstroke as much as possible.

When the destination of the drive recorder 10 is the server 32, access information to the server 32 can be registered in advance at the time of shipping the drive recorder 10, for example, and the user who purchased the drive recorder 10 can send the drive recorder 10 to the server 32. This is good because there is no need to register destinations such as the user's phone number and address. The drive recorder 10 is, for example, small, and when it is installed, it may be hidden behind the rearview mirror at a predetermined position above the windshield, making it difficult to perform operations such as setting the mode. This is advantageous because it eliminates the need for processing on the drive recorder 10 for this purpose. The user can receive the notification via the server, for example, by accessing the server 32 and registering information on the smartphone or the like for which the user wants to receive the notification. Access and registration processing for the server 32 can be performed relatively easily.

Further, even after performing the above transmission, the control unit 16 acquires an image taken by the camera 11 at an appropriate timing, performs image analysis, and determines whether there is a person or not. When a person is detected in the image, the control unit 16 transmits predetermined information to the registered destination using the communication unit 24. The predetermined timing may be on the order of minutes, such as from several minutes to more than ten minutes. It is good to receive periodic notification that there is a child in the vehicle, as this will remind the driver of the child's presence and provide an opportunity to return to the vehicle as soon as possible.

Further, the predetermined information may be not only the recognition result but also an image taken by a camera, temperature information and humidity information detected by the temperature/humidity sensor 23, or the like. In this way, if a child is left in the vehicle and gets off the vehicle, the status of the interior of the vehicle will be periodically sent to the driver's mobile device such as the smartphone 33, so if something happens, it will be easier to return to the vehicle. This is good because it can prevent accidents from occurring. For example, if you send an image taken by the camera 11 as the predetermined information, for example, if you leave the child in the vehicle because he or she was asleep when you got off the vehicle, you can know that the child has woken up and return to the vehicle immediately. This is good because it provides an opportunity for further study. In addition, if the predetermined information is temperature information, humidity information, etc., the driver, etc. who is located far away from the vehicle, can be aware of temperature changes such as temperature rises and temperature drops, and humidity changes at an early stage, thereby preventing heat stroke. This allows the driver to return to the vehicle and take action before the environment becomes dangerous, causing hypothermia or other conditions.

On the other hand, if the result of image analysis is that no person is present, the control unit 16 does not transmit the image to the server 32, smartphone 33, or the like. By communicating in this way when there is an abnormality, etc., it is possible to reduce the number of times of communication and the amount of communication data. That is, the photographed image may be sent to the server and the image analysis may be performed on the server side, but it is preferable that the judgment is made on the edge side such as the drive recorder 10 as in this embodiment, and communication is made only when there is an abnormality. If there is no abnormality, the image is not transmitted, which is good because the amount of communication data can be reduced. Furthermore, by processing on the edge side, it is possible to avoid including an image as the predetermined information to be transmitted in the event of an abnormality, thereby further reducing the amount of data.

Furthermore, the predetermined information to be transmitted may be the same or different each time. For example, when switching to monitoring mode, the first notification may be to notify that a person is present and do not send other information such as images, but after a predetermined number of times or a predetermined period of time, images, etc. may be sent. . Since the first notification is often made when the driver is in or near the vehicle, the driver can visually confirm the presence of the child directly. Further, even if a predetermined number of times or a predetermined time has elapsed, information with a large amount of data such as an image may be sent, for example, once every several times. By doing this, the communication load can be reduced, the presence of a child can be notified efficiently and quickly, and the actual situation can be notified with images from time to time to provide a more realistic feeling, allowing the driver to return to the vehicle sooner. This is good because it can encourage

If the result of image analysis is that no person is present, it is preferable not to perform further analysis. If no one is present, whether the child has been left behind or because the child has been taken out, subsequent image analysis will continue to produce an analysis result of "no one is present." Therefore, the load on the drive recorder 10 can be reduced by not performing the analysis process itself. Further, even if an analysis result of "does not exist" is obtained once, there is a risk of an erroneous determination, so if, for example, an analysis result of "does not exist" is obtained multiple times, it is preferable not to perform subsequent analysis.

In addition, in the embodiment described above, the presence or absence of a person is determined by image analysis, and if there is a person, the notification is made. It's good to do that. The second information may be, for example, the detection result of the temperature/humidity sensor 23. For example, when switching to monitoring mode, it is transmitted only based on image analysis if a person is detected, and then after a predetermined number of times or a predetermined time has elapsed, second information is sent when a person is detected. It is a good idea to send the message when the temperature or humidity exceeds a set threshold, or when there is a large change in temperature or humidity, and not to send it if the temperature, etc. is within a predetermined range even if a person is detected. . If you intentionally leave your child in the car, receiving a warning continuously can be bothersome, and there is a risk that the child may become accustomed to the warning. In contrast, in this embodiment, the information is not transmitted when the temperature inside the vehicle is in a state where there is no risk of causing heatstroke, etc., but is transmitted when the temperature is likely to rise or become dangerous, so that the driver, etc. This is a good idea because it notifies you of the emergency and gives you an opportunity to return to your vehicle immediately.

In addition, for example, when there are people inside the car, the temperature inside the car is monitored, and if the temperature inside the car rises or falls above a certain level, predetermined information is sent to the driver, etc. Instead of the notification function, or in addition to this function, it is preferable to automatically start the air conditioner. In this way, the temperature inside the vehicle will be within the appropriate range before the driver returns to the vehicle, and the safety of those remaining in the vehicle will be maintained. Such a function would also be useful as an insurance product that utilizes connected cars, for example.

In addition, image analysis should be able to recognize not only the presence or absence of a person, but also the condition of the person. It is good to be able to recognize a person's state, such as sleeping/awake/crying. Then, it is preferable to send the recognition result.

Further, in the embodiment described above, the fact that the ACC has been turned off is detected based on the signal from the power supply device 30, but the present invention is not limited to this, and the fact that the ACC has been turned off is detected based on the signal from the power supply device 30. For example, it may be obtained directly from the vehicle, and may be detected using various methods.

On the other hand, if the vehicle is parked or stopped without turning off the engine, the ACC will not turn off. Therefore, for example, it is preferable to include means for detecting when the driver gets off the vehicle, and to perform the above-mentioned process when it is detected that the driver gets off the vehicle. For example, a seating sensor installed in the driver's seat may be used as the means for detecting when the driver exits the vehicle. The seating sensor is turned on when a person sits in the driver's seat, and turned off when a person stands up from the driver's seat. Then, when the seating sensor installed in the driver's seat turns from ON to OFF, it may be determined that the driver gets out of the vehicle. Additionally, it is recommended to install a sensor that detects the opening/closing of the driver's side door, or to acquire information on the opening/closing of the door from the vehicle.For example, when the driver's door opens from the closed position, it may be determined that the driver has exited the vehicle. . Furthermore, various methods may be used, such as setting the imaging range of the camera to include the driver's seat and determining whether or not there is a person in the driver's seat through image analysis.

*Detection based on sound For example, when switching to the monitoring mode, the control unit 16 acquires the sound detected by the microphone 12 and analyzes the sound. Speech analysis is preferably performed using a method using deep learning (neural network) or other machine learning. When the control unit 16 detects an abnormal sound through audio analysis, it transmits predetermined information to the registered destination using the communication unit 24. The predetermined information may be an analysis result, and in addition to the analysis result, location information, room temperature, humidity, etc. may be sent. Examples of abnormal sounds include glass breaking sounds, collision sounds, screams, and cries. The scream may be, for example, a child's cry such as "Help me". The cry includes, for example, the cry of an infant. The analysis result to be sent may be the presence or absence of abnormal sounds, but it is also preferable to send the analyzed content.

For example, if the driver leaves a sleeping child in the vehicle when getting off the vehicle, the driver can know that the child has woken up by, for example, a scream or cry, which provides an opportunity to return to the vehicle early. In addition, by learning about abnormalities that occur in the vehicle such as the sound of breaking glass or collision sounds, you can go to check on the vehicle, and especially if you have left a child in the vehicle, you may need to return more quickly. It's good because you can know.

The sound analysis may be performed by various types of analysis using a database or the like to determine what kind of sound it is. Furthermore, the audio analysis is not limited to sounds generated inside the vehicle, but may be performed based on ambient sounds outside the vehicle. For example, if a person who found a child left behind in a car is making a noise outside the vehicle, the control unit 16 recognizes whether the child has been left behind or the condition of the child inside based on the content of the recognized voice. It is a good idea to send it.

Further, the operation timing, information to be transmitted, etc. in this sound-based detection can be made similar to the embodiment and modification example in the image-based detection described above. For example, it is preferable to add information such as temperature and humidity to the information to be sent in the same way as the analysis results, or to add information such as an indoor image taken with a camera. In addition, various elements can be applied, such as providing means for detecting when the driver gets off the vehicle and starting the operation after detecting the driver getting off the vehicle.

*Detection based on microwave sensor When switching to the monitoring mode, for example, the control unit 16 acquires the output of the microwave sensor 22 and determines the presence or absence of an object moving inside the vehicle. If there is a moving object, there is a possibility that a child or the like is present in the rear seat 3 or child seat 4, so predetermined information is transmitted to the registered destination using the communication unit 24. Further, the detection based on the microwave sensor 22 may be performed periodically even after the transmission is performed once, as in each of the above-mentioned examples, and the determination result etc. may be output.

Further, the moving object based on the microwave sensor 22 is not limited to a person, but may also be able to detect an animal inside the car. In this way, it becomes possible to detect if a pet is left behind.

In each of the above-described embodiments and modifications, the drive recorder 10 is used to send predetermined information to a registered destination when an abnormality is detected, but it is not always sent to the outside and is set to monitoring mode. In a situation where the driver is present in or near the vehicle, such as immediately after switching, the speaker 19 of the drive recorder 10 may issue an alarm, for example.

Further, in each of the embodiments and modifications described above, power is supplied from the power supply device 30, but power is supplied directly from the vehicle battery so that power can be supplied even after the ACC is turned OFF. Alternatively, it may be provided with an internal battery and receive power from the internal battery after the ACC is turned off. In such a case, the internal battery may be a rechargeable secondary battery.

In addition, in each of the embodiments and modifications described above, it is implemented as part of the function of the drive recorder, but it is not limited to the drive recorder, and it may be implemented as part of the function of various in-vehicle equipment, electronic equipment, etc. It would be better to realize it as an independent device/equipment.

For example, in the case of a system using image analysis, a camera that is compatible with LTE communication and capable of edge AI processing may be used. This camera is an AI camera that integrates a communication module, SIM card, camera, and power supply, and is capable of edge processing. Additionally, devices can be managed remotely via cellular lines, such as replacing AI algorithms and monitoring communication connection status. It is preferable to perform deep learning and implement relatively easy detection of a person through image analysis using, for example, NNC (Neural Network Console). This AI-enabled camera photographs the rear seat side, including a child seat, for example, and performs AI processing on the resulting image to analyze the presence or absence of a person. For example, when a person is detected in the image, it is preferable to operate a communication module and transmit the detection result to a predetermined destination.

[Alarm based on seating sensor installed in child seat]
FIG. 3 shows a block diagram of another embodiment of the system. The system of this embodiment is another embodiment for preventing infants and the like from being left behind in a car, and as shown in the figure, includes a main body device 40, a seating sensor 41, and the like. In this embodiment, it is configured as a dedicated device, but it may be implemented as a function of a drive recorder or other in-vehicle equipment, or it may be realized as an independent device or device. Further, the main body device 40 may be configured from the same casing or a plurality of casings.

In this embodiment, for example, the seating sensor 41 is installed in a child seat. It is preferable that a plurality of seating sensors 41 be provided and arranged at appropriate positions on the seat surface and backrest of the child seat. The seating sensor 41 is turned ON when an infant or the like is riding in the child seat, and turned OFF when the child is not seated. The main body device 40 includes an interface section 43 that receives an input signal from the seating sensor 41, a control section 42, a speaker 45, an interface section 46 that outputs a control signal to the vehicle side, and the like.

The interface section 43 for the seating sensor 41 includes, for example, a pin jack or connector into which an output terminal section of the seating sensor 41 is inserted, and transmits the output signal of the seating sensor 41 to the control section 42 . The control unit 42 has a function of outputting an alarm from the speaker 45 when the driver leaves the driver's seat or stands up when an infant or the like is in the child seat. The control unit 42 also has a function of outputting a signal to the vehicle to prevent the door from being locked via the interface unit 46 when a predetermined condition is satisfied.

In order to realize this function, the control unit 42 determines whether the seating sensor is ON or not, as shown in FIG. 4, for example (S1). If the seating sensor is OFF, there is no baby or the like, so S1 is looped.

When an infant or the like is riding in a child seat, the control unit 42 determines whether the driver is away from the seat or not. Examples of leaving the driver's seat include leaving the driver's seat or standing up from the driver's seat in preparation for leaving the driver's seat. The determination of leaving the seat, etc. may be based on, for example, a seating sensor provided in the driver's seat and the output of the seating sensor being turned OFF or the ACC being turned OFF. "Based on this" may mean that the user immediately leaves the seat or the like (the branch decision is Yes) when such a state occurs, but it may also be such that the branch decision is made Yes after a predetermined period of time has elapsed. It is better to immediately determine that the driver has left the seat, etc., so that the alarm will surely sound before the driver leaves the vehicle. Furthermore, for example, if the driver has a child device that can communicate wirelessly with a parent device installed in the vehicle, and the distance between the parent device and the child device is a certain distance or more, it may be determined that the driver is leaving the seat. Further, for example, a camera may be provided to photograph the driver's seat, and the image taken by the camera may be analyzed to determine whether the driver has left the seat or not.

If the driver has not left the seat (No in S2), the process returns to S1 to determine whether the seating sensor is ON or OFF. If the driver's seat is away (Yes in S2), the control unit 42 issues an alarm from the speaker (S3). The warning may be a buzzer sound or an audio warning message. In this way, the driver will be alerted to the fact that a child, such as an infant, is in the child seat, and will forget about the child's presence and get out of the car. It can be suppressed.

Furthermore, in this embodiment, the control unit 42 disables the vehicle doors from being locked after generating the alarm (S4). For example, the control unit 42 outputs a door unlock signal to the vehicle via the interface unit 46. As a result, the vehicle door remains unlocked, and even if a child is left in the vehicle, a third party (finder) can open the vehicle door and rescue the child. It also becomes possible.

Then, when the seating sensor is turned off (Yes in S5), the control unit 42 releases the lockable state and makes lockable (S6). As a result, the child seat can be locked by removing the child or the like from the child seat, and the driver can, for example, perform a lock operation to lock the seat and leave the vehicle with peace of mind.

Additionally, by attaching a seating sensor to the child seat itself, it is possible to detect which seat the child seat is installed in. Furthermore, it is preferable to connect this system to a drive recorder, use the above-mentioned unlocked state as an external trigger, and have the drive recorder notify the smartphone or server. It is preferable that such a notification sends predetermined information including video, similar to the above-described embodiments.

As described above, by making the decision to leave the seat conditional on the ACC being turned off, it is possible to alert the driver when the engine is turned off with a child seat in the car and a child present. Further, by setting the alarm to be issued by turning off the engine, for example, when the driver takes the child out of the child seat himself, it is possible to suppress unnecessary alarms by leaving the engine running.

FIG. 5 shows another embodiment using a seating sensor. In this embodiment, for example, the function of determining whether the driver is leaving the seat, etc. in the control unit 42 in the system shown in FIG. There is. Similarly to the above, the control unit 42 determines whether the seating sensor is ON (S11). If the seating sensor is OFF, there is no baby or the like, so S1 is looped.

If the seating sensor is ON, the control unit 42 determines whether the door on the driver's seat side is open (S12). If the door is closed, the process returns to S11. If the door is opened, the control unit 42 waits for the door to close next (S13). Then, when the door is closed (Yes in S13), the control unit 42 issues an alarm from the speaker (S14). The warning may be a buzzer sound or an audio warning message. In this way, the driver will be alerted to the fact that a child, such as an infant, is in the child seat, and will forget about the child's presence and get out of the car. It can be suppressed.

Furthermore, in this embodiment as well, after generating the alarm, the control unit 42 disables the vehicle doors from being locked (S15). As a result, even if a child is left in the car, a third party (finder) can open the door of the vehicle and rescue the child.

Then, when the seating sensor is turned OFF (Yes in S16), the control unit 42 releases the non-lockable state and makes lockable (S17). This allows the child seat to be locked by removing the child, etc. from the child seat, allowing the driver to leave the vehicle with peace of mind.

In the embodiment described above, the alarm is issued after the door is opened and the alarm is issued after the door is closed, but the alarm may be issued when the door is opened without providing the processing step S13. However, in order to let down a child in a child seat, the driver often opens the driver's door and moves outside the vehicle to reach the rear seat. If the door is opened, an alarm will sound, which may cause annoyance to the driver. Therefore, as in this embodiment, by setting the door closing as a condition for the alarm, for example, if the child is removed from the child seat with the door open, and then the driver's side door is closed, the alarm will be triggered. It's good because it doesn't make any noise.

In each of the embodiments shown in FIGS. 4 and 5, instead of disabling locking in S4 and S15 so that the lock cannot be locked even if the locking operation is performed, an alarm is issued when an attempt is made to lock the lock. Good too. In this case, the warnings in S3 and S14 do not need to be issued, but if they are done, a double warning can be issued.

Further, instead of disabling locking in S4 and S15, it is preferable to lock after an alarm or to enable locking when a lock operation is performed again after an alarm. This makes it possible to prevent suspicious persons from entering the vehicle by leaving the child or the like in the vehicle at the driver's will and locking the vehicle.

[Communication type temperature measuring device]
FIG. 6 shows an example of a system that prevents heatstroke in children left inside the car based on the temperature inside the car. The system 50 of this embodiment includes a function to measure the temperature inside the vehicle (for example, a temperature/humidity sensor 51), a communication function (for example, a communication section 52), a control section 53 that controls these functions, and the like. When the temperature inside the vehicle exceeds the set temperature, the control unit 53 uses the communication function to notify the registered destination. For the communication function, for example, an LTE-M module capable of LTE communication may be used, and notification is sent to, for example, the server 32 or the driver's smartphone 33 registered in advance. When transmitting to the server 32, it is preferable that the notification is sent to the driver's smartphone 33 or the like via the server.

This system is installed in a vehicle, and when the temperature inside the vehicle approaches a temperature that could cause heatstroke after the engine has stopped, a notification is sent to the driver's smartphone, etc., alerting the driver that danger is approaching. In this way, the driver receives the notification and heads to the vehicle to take appropriate measures to prevent high temperatures inside the vehicle. Further, in this embodiment, a function for determining whether a child is present in the vehicle may be provided as in each of the above-described embodiments, but the configuration may be simplified by not providing such a function.

Further, the engine stoppage such as when the ACC is turned off may be detected, and then the room temperature may be monitored and a notification may be made when a condition is met, but the engine stoppage detection function does not necessarily have to be provided. Generally, when the driver is in the car, the engine is running, and the car is ready to drive, there is a risk that the room temperature will rise to a dangerous level that could lead to heat stroke, for example, by using the air conditioner or opening the windows. low. Therefore, the temperature inside the car often exceeds the set temperature when the car is parked with the engine turned off. Therefore, by not providing an engine stop detection function, it is possible to install the system independently from the vehicle, and it is possible to effectively take measures against heatstroke and the like with a simple configuration.

In this case, by sending a notification to your smartphone when the temperature is high, you can respond not only if you leave your child behind, but also if you leave the vehicle for a short period of time. In addition, by setting the temperature to be notified appropriately, it is possible to notify the user in advance from the warning stage, and to rush to the emergency room before the temperature reaches a dangerous level. It is preferable that the temperature to be notified is set to an appropriate value as an initial value, taking into consideration the temperature at which there is a risk of heat stroke, and that the user can change the temperature in the settings.

Although temperature is one of the important factors in heatstroke, humidity also plays a role. Therefore, it is preferable to provide a function to measure temperature and humidity, and to issue a notification when the relationship between temperature and humidity satisfies a predetermined condition. If humidity is taken into consideration, it is possible to notify even if the temperature is relatively low, even if the environment is such that there is a risk of heatstroke due to the humidity.

[Communication type temperature measurement device + remote compatible operation]
In addition to the functions of the embodiment of the communication type temperature measuring device described above, it is preferable to have a function of connecting to the OBD and remotely opening a window or starting an engine. In this way, for example, when a notification of high temperature is received on the driver's smartphone, instructions such as "Do you want to open the windows fully?" or "Do you want to start the engine?" are displayed on the smartphone screen. When the "YES" button displayed on the screen is touched, remote operation becomes possible. By opening the windows to let in outside air or turning on the air conditioner in advance, the interior of the car can be cooled down by starting the engine, making it possible to prevent heatstroke in children before rushing to the vehicle.

In this embodiment, this function is effective when the situation is such that even if a notification is received, it is not possible to rush immediately. Furthermore, even in situations where it is possible to return to the vehicle immediately, by responding immediately, the child can be released from a dangerous situation as quickly as possible.

Further, it is preferable that such remote control be performed only in dangerous cases. In this way, it is possible to suppress as much as possible the occurrence of situations such as a window opening unnecessarily to allow entry and exit, or an accidental start due to the engine starting.

[In-vehicle drive recorder (with motion detection)]
For example, the photographing area of the drive recorder camera shown in FIGS. 1, 2, etc. is set inside the vehicle. It also has a function of registering, for example, the driver's smartphone 33 as a transmission destination of the communication unit 24, linking the drive recorder 10 and the smartphone, and transmitting the image being captured by the drive recorder to the smartphone. This allows the user to check the status of the child in the back seat in real time from their smartphone. Also, for example, you can check on your child from a distance using LTE communication. Furthermore, it is preferable to use a drive recorder specialized for in-vehicle recording. Furthermore, if the drive recorder is equipped with a temperature sensor so that the temperature inside the car is also displayed at the same time, this will lead to early detection of heatstroke. It is even better if a humidity sensor is installed to display the humidity as well as the temperature. For example, in the example shown in FIG. 2, since the temperature and humidity sensor 23 is provided, both temperature and humidity can be displayed.

In addition, the above-mentioned video can be checked by, for example, having a method in which the user voluntarily connects to the drive recorder and viewing it, and a method in which the drive recorder sends the video to the smartphone when there is movement in the car due to motion detection. It is often a good idea to allow selection in user settings. Equipped with a motion detection function is also useful for crime prevention while parking.

[Smart band]
FIG. 7 shows yet another system embodiment. The system of this embodiment includes a smart band 60. This smart band 60 includes a band portion 60a for being worn on, for example, a child's foot, leg, arm, or the like. The smart band 60 includes a biometric information acquisition sensor 61 that measures biometric information such as body temperature, heart rate, and blood pressure of the wearer of the user, a communication unit 62 that transmits the biometric information to the smartphone 33, and a communication unit 62 that transmits the biometric information to the smartphone 33. It includes a control section 63 and the like that performs control. Then, the smart band 60 is worn on the child's foot, leg, arm, etc., for example. Thereby, for example, biological information such as the body temperature and heart rate of a child waiting in the car can be constantly monitored using the smartphone 33 held by a user who is away from the vehicle.

Further, the smart band 60 may be worn on the feet or legs, for example. For example, if the smart band 60 is worn on the arm, a child sitting in a child seat or the like may touch the smart band 60 and remove it, turn off the power, or cause a malfunction. On the other hand, when the smart band 60 is worn on the foot or leg, it is difficult to reach the smart band 60 in such a state, and the above-mentioned problems can be suppressed as much as possible.

It is preferable that the smart band 60 has a function of sending a notification to the smartphone 33 when the child wearing the smart band 60 is in a dangerous situation. An example of a situation in which a child is in danger is a case where the detection value of the biological information acquisition sensor 61 exceeds a preset threshold value. Further, this smart band may be configured to eliminate a screen and specialize in transmitting information. Not having a screen reduces costs, simplifies the configuration, and makes it smaller and thinner, but if a screen is provided, there is a risk that children may become interested and touch the screen, etc. This is good because it can prevent this from happening as much as possible.

Furthermore, although the notification destination of the smart band is a smartphone in the above-described embodiment, the notification destination is not limited to this, and may be transferred to, for example, a smart watch carried by the user. Since you may not carry a smartphone with you at home, it is a good idea to use a smartwatch that is easy to wear and easy to check notifications.

Further, the present embodiment is not limited to being attached to a child left in a vehicle, and can be used not only in a car but also at home or on the go. For example, since there are times when both parents are separated from their children at home, this would help prevent unexpected accidents at various locations.

In the embodiments described above, a case has been described in which GPS is used as the satellite positioning system, but GLONASS, Galileo, quasi-zenith satellite systems, etc. may also be used without departing from the spirit of the present invention.

Note that the scope of the present invention is not limited to the configuration explicitly described in the specification, but also includes combinations of various aspects of the invention disclosed in this specification.
