Application of Article 30, Paragraph 2 of the Patent Law Posting address https://my. yupiteru. co. jp/upload/save_image/manual/pdf/S10_quickguide. pdf (published on August 21, 2017) https://www. yupiteru. co. jp/products/biz_dr/s10/ (published on September 4, 2017) http://www2. yupiteru. co. jp/manual/pdf. php? pdfname=S10 (Posted on September 4, 2017) Others 5

For example, it relates to systems and programs.

Conventionally, when the power supply from the vehicle is cut off, such as when the vehicle is parked, the drive recorder continues to receive power from the vehicle's battery or a battery separate from the vehicle's battery, and is equipped with a function to record images while the vehicle is parked. Recorders are known.

JP 2017-195755 A

Although it is possible to record images when the vehicle is parked, it is not sufficiently user-friendly.
Therefore, it is an object of the present invention to provide a system, a program, and the like that are superior to the conventional systems, such as being easier to use than the conventional ones.

The purpose of the invention of the present application is not limited to this, and we intend to acquire rights for the configuration aiming to obtain the effect produced by the configuration disclosed in the specification and drawings by divisional application, amendment, etc. . For example, the present specification discloses a problem in which the phrase "can be done" is read as "is the problem." The problems are described as independent ones, and we intend to acquire the rights for the structure for solving each problem independently by filing a divisional application, an amendment, etc. Even if the problem is implicitly grasped from the description of the specification, the applicant intends to claim part of the structure described in this specification in an amended or divisional application. It also discloses a configuration that solves a problem that combines these independent problems, and has the intention to acquire the right.

(1) A system having a function of recording video captured in a vehicle while the vehicle is parked, and having a function of detecting an approach of a user of the vehicle to the vehicle. It is preferable that the system has a function of canceling recording while the vehicle is parked when an approach to the vehicle is detected.
In this way, it is possible to realize a system that is more user-friendly than the conventional system. Recording can be canceled simply by approaching the vehicle in which the user is parked.

For example, when a user approaches a vehicle, if the user of the vehicle appears in the image captured by the parking surveillance camera, the image is wasted, and the image recording area such as the recording medium is wasted. However, in this way waste can be reduced. For example, as the approach, it is preferable to set the approach to the extent that it is possible to recognize that the user is getting into the car. In this way, when you get into the car, if you appear in the image taken by the parking surveillance camera, you will leave a useless image, and the image recording area such as the recording medium will be wasted. However, in this way, waste can be reduced.

The vehicle may be, for example, a bicycle or a motorcycle, but it is preferable to use an automobile. The vehicle may be a passenger vehicle such as a bus or a taxi, but is particularly preferred to be a privately owned car or a company car.

For example, when the vehicle is parked, it may be a state in which the power of the vehicle engine or the electric vehicle is turned off. For example, connecting to a car battery or receiving power from a separate battery from the car battery to operate the system, and monitoring the power supply from the cigar socket, the power supply from the cigar socket If there is no power supply, it may be determined that the power of the vehicle engine or the electric vehicle is turned off.

The users may be all of the passengers of the vehicle, but it is preferable to use at least some of them. The user may be a fellow passenger, but is particularly preferable to be the driver of the vehicle. Whether or not the user is the user may be determined, for example, based on whether or not an image similar to a pre-registered user image has been captured.

For example, when the vehicle is parked, it is preferable that the driver is not in the vehicle. The function of detecting whether or not the driver is not in the vehicle may be determined, for example, based on whether or not the pre-registered driver of the vehicle is present in the images captured in the vehicle. .

It is preferable to use a camera installed in the vehicle for imaging, and a wide-angle camera is particularly desirable. More preferably, it should be an omnidirectional camera. The imaging direction may be, for example, the inside of the vehicle or the direction from inside the vehicle to outside the vehicle. In particular, it is preferable to adopt a configuration that allows photographing both inside and outside the vehicle. As such a configuration, for example, imaging is performed by two cameras, one for inside the vehicle and one for outside the vehicle, or a configuration in which one half-sphere camera is installed facing downward from the ceiling inside the vehicle. should be

For recording, for example, a photographed image may be recorded in a recording means, but it is particularly preferable to digitize it and record it in a recording means. As for the digitized recording, it is preferable that the information is compressed and recorded. The recording means may be provided in the vehicle, or may be provided in a server or the like connected by communication. The recording means is preferably a detachable recording medium. The recording means may be a non-volatile memory. The recording means is preferably a semiconductor memory. It is particularly preferable that the recording means is a card-shaped recording medium. It is particularly preferable to use an SD card as the recording means.

The video recording may be performed, for example, simply by recording the video data continuously, but it is particularly preferable to record the video data in a file for each predetermined unit. The predetermined unit may be when a specific end condition is satisfied. For example, the end condition may be every predetermined time from the start of file recording. For example, one file may be generated every minute.

The system may be composed of a single chassis, or may be composed of a plurality of chassis and electrically connected by wire or wirelessly. Part of the system may be outside the vehicle. For example, part of the system may be configured as a server, but in particular, the system may be configured entirely within the vehicle.

It is preferable that recording is not performed as cancellation. For example, when a vehicle user approaches the vehicle, it is preferable not to record the image captured in the vehicle. Cancellation may be, for example, a temporary stop of recording, but it is particularly preferable to stop recording. Recording may be stopped by closing the file in which the video is being recorded.

The approach of the user of the vehicle to the vehicle may be detected, for example, by detecting that the door of the vehicle has been opened by the user.

(2) The detection of the approach of the user of the vehicle to the vehicle may be performed based on whether or not the user of the vehicle is within a predetermined range outside the door of the vehicle.
In this way, the recording while the vehicle is parked is canceled only by the user of the vehicle approaching within a predetermined range outside the door of the vehicle.
(3) It is preferable that the detection of the approach of the user of the vehicle to the vehicle is performed based on the state of radio waves with a terminal that the user can carry.

In this way, approach can be detected more reliably. For example, the approach can be detected more reliably than the recognition of the user by the recognition of the captured image. Also, for example, the user can detect the terminal without taking it out of a storage location such as a bag or pocket one by one.

A terminal that can be carried by the user should preferably be a battery-driven device. For example, a remote control, a key, a tag, etc. may be used, but a smart phone is preferable. The inventors found that smartphones are highly likely to be taken out of the vehicle by vehicle users.

As the radio wave, for example, LTE or the like may be used, but it is particularly preferable to use a radio wave with a communication distance of several meters to ten and several meters. In particular, it is preferable to use Bluetooth (registered trademark, hereinafter the same). In particular, it is preferable to use a beacon, and it is preferable to use a Bluetooth beacon.

As a configuration to be performed based on the radio wave state, for example, it may be possible to detect approaching the vehicle when radio waves from the terminal can be received. It is good to assume that the approach to the vehicle is detected at this time. More preferably, (4) should be used.

(4) The detection of the approach of the user of the vehicle to the vehicle may be performed based on the strength of radio waves used for communication with a terminal that the user of the vehicle can carry.
In this way, there is no need to provide a transmitter and a receiver of radio waves for distance detection, which are separate from the transmitter and receiver of radio waves used for communication.

Regarding detection of approaching a vehicle, for example, approaching a vehicle may be detected when the reception strength of radio waves emitted from a terminal that the user can carry in the system reaches a predetermined level. In particular, the reception strength of radio waves emitted by the system is measured by a terminal that the user can carry, the measured reception strength is transmitted to the system, and the reception strength received by the system reaches a predetermined state. In this case, it is preferable that the approach to the vehicle is detected. By doing so, it is possible to suppress the consumption of the battery of the terminal that the user can carry. These predetermined states may be, for example, when the received signal strength is equal to or greater than a predetermined level.

(5) Detection of approach of the user of the vehicle to the vehicle is performed by transmitting a radio wave whose strength can be measured by a terminal possessed by the user of the vehicle at a predetermined cycle from the system side, and detecting the approach of the vehicle. A system that measures the strength of radio waves transmitted from the system at a predetermined cycle by a terminal that the user can carry, transmits information on the measurement results, and performs operations based on the information on the measurement results. do it.

In this way, battery consumption of the terminal can be suppressed. The battery capacity of the terminal is often extremely small compared to the vehicle, and transmission often consumes much more power than reception. can reduce the power required for

In particular, the strength of the radio wave transmitted from the system side at a predetermined cycle is measured by a terminal that can be carried by the user of the vehicle, and if the measurement result is equal to or greater than the predetermined strength, information about the measurement result. and the system may act upon the information about the measurement results. In this way, the power consumption of the terminal can be greatly reduced, and the battery driving time of the terminal can be extended.

The predetermined cycle is at least once during the time from when the user approaches the vehicle on foot and the terminal enters the area where radio waves transmitted from the system can be received until the user arrives at the vehicle. An interval that allows reception is desirable, and an interval that allows reception at least several times is particularly desirable. The predetermined cycle is preferably set to a time shorter than the time required for a person to walk several steps. The predetermined cycle may be, for example, 3 seconds or less. On the other hand, if the predetermined period is too short, problems arise. The predetermined time is preferably set to a time longer than or equal to the time during which battery consumption of the terminal can be suppressed. In addition, the inventor found a problem that, when the terminal has an application execution function, the operation of the application does not proceed smoothly if there are frequent reception events. Therefore, it is preferable to set the time longer than the time that does not affect the operation of the application. Taking all of these into consideration, it is best that the predetermined cycle is about 2 seconds. In this way, it is possible to further reduce battery consumption of the terminal, and other programs such as applications can be operated smoothly, and when the user approaches the vehicle, an appropriate proximity relationship can be established. You can then cancel the recording. For example, if the terminal is a smartphone and the system is configured as a camera, when the user walks and approaches the camera equipped with a beacon, the smartphone will frequently receive signals, so the battery consumption of the smartphone should be reduced. It is preferable that the area can be determined by moving about 3 or 4 steps. Also, if beacons are sent at short time intervals, the smartphone will receive all the beacon signals, so reception events will occur frequently and the application will not operate smoothly. Then, such problems can be suppressed.

The information about the measurement results may be the level of reception, and recording may be canceled when a predetermined condition is met, such as when the level of reception received by the system exceeds a predetermined value. is preferably a signal requesting to cancel the recording, and the terminal transmits a signal requesting to cancel the recording when a predetermined condition is satisfied, such as when the strength of the radio wave measured by the terminal exceeds a predetermined value, and the system Then, when this signal is received, recording should be canceled. By doing so, it is possible to further suppress the consumption of the battery of the terminal.
The radio wave is preferably a beacon signal. The radio wave is preferably an advertising signal.

For example, the system may be a parking surveillance camera equipped with a function capable of transmitting beacons, and the terminal may be a smartphone/tablet capable of executing an application equipped with a function capable of receiving beacon signals transmitted from the camera. For example, a Bluetooth beacon signal is periodically sent from the camera (every 2 seconds for the product), and when a person holding a smartphone with a special app installed approaches the parking surveillance camera, the smartphone app receives the Bluetooth beacon signal. Then, connect to the camera via Bluetooth, and every time it periodically receives a periodic monitoring notification message from the camera, it acquires the RSSI value and detects the approximate distance to the camera. When the RSSI value reaches or exceeds a preset RSSI value, the parking monitoring operation of the camera should be canceled by making a Bluetooth connection with the camera and stopping the parking monitoring mode.

The Bluetooth beacon should be advertised on the camera side, and a UUID (Universally Unique Identifier) dedicated to the beacon should be created and periodically transmitted.

As a Bluetooth beacon, it is good to transmit ID information called an advertisement packet from the beacon.

The configured ID information may be transmitted periodically. The proximityUUID, Major, and Minor identifiers can be determined arbitrarily, but for example, the proximityUUID should be a common ID for all systems, and the Major and Minor codes should be different for each individual system. In this way, even when a plurality of systems are nearby, video recording can be canceled or started (to be described later) only when a specific system is approached. Then, when pairing the major code and minor code with the camera and the smartphone app, it is better to receive them as message data. If the app knows that the user has re-paired or unpaired, this Major/Minor code should be updated or cleared.

(6) having a function of receiving, via wireless communication, an operation signal of a terminal that a user of the vehicle can carry, and having an operation of canceling recording while the vehicle is parked as an operation of the terminal; It has a function to cancel the recording while the vehicle is parked when an operation to cancel the recording while the vehicle is parked is received, and when the approach of the user of the vehicle to the vehicle is detected, the vehicle is parked. It is preferable that the system cancels the recording while the vehicle is parked even if the operation to cancel the recording while the vehicle is parked is not received.

This eliminates the need for the user to take out the terminal held by the user when approaching the car to cancel the recording while the car is parked. Therefore, troublesome operation when getting into the car is eliminated.

(7) Communicable with a terminal that the user can carry in a first range, which is a range that includes a range farther than the second range, which is a range for detecting approaching to the vehicle, and is near the vehicle. communication function, and a function of transmitting information about the situation detected while the vehicle is parked in the first range.

In this way, the terminal that the user can carry can acquire information about the situation detected while the vehicle is parked when approaching the vehicle up to the first range, and the user can use the vehicle more than the first range. Recording is canceled while the vehicle is parked in the second range approaching . In particular, it is preferable that the terminal that the user can carry has a function of receiving information about the situation detected while the vehicle is parked from the system and notifying the information. In this way, when the user approaches the vehicle to the first range, the user can obtain information about the situation detected while the vehicle is parked, and the user can obtain the information about the situation detected while the vehicle is parked. Recording is canceled while the vehicle is parked in two ranges. If the user only approaches the first range but does not enter the second range, it is possible to simply obtain information about the situation detected while the vehicle is parked without canceling the recording. For example, if an abnormality is not reported, the user does not approach the vehicle any more, or leaves the vehicle to do some work.

The situation detected while the vehicle is parked may be, for example, a recognition result such as the state of a suspicious person appearing in the captured image. The situation detected while the vehicle is parked may be the acquired information regarding the state of the vehicle. The function of acquiring the state of the vehicle may be implemented by providing a sensor or the like in the system, or may be implemented by acquiring from an in-vehicle LAN or the like that the vehicle originally has.

The information about the situation detected while the vehicle is parked is preferably information about an abnormality of the vehicle. In this way, it is possible to immediately check whether there is an abnormality in the vehicle when approaching the vehicle under parking monitoring.

The information regarding the situation detected while the vehicle is parked may be battery information or tire pressure information. In this way, when approaching a parked car, the battery information, tire pressure, etc. can be checked each time.

The first range may be a communication range provided with a communication function, particularly a range of about ten and several meters. The second range is preferably about 6 m, for example. Since people walk at various speeds, if the distance is too short, the driver will be reflected in the parking surveillance video. . Also, for example, when the driver approaches the car, the Bluetooth connection is made and the RSSI is checked every 2 seconds. By the way, about 6m is desirable.
(8) It is preferable to provide an adjustment function for adjusting the second range by a user's operation.

In this way, the user himself/herself can set how close to the vehicle the video recording is to be canceled. For example, it is preferable to have a configuration in which approach is detected by the intensity of radio waves, and to have a function of setting the intensity of the second range by user's operation. For example, it is preferable to provide an RSSI level setting function. By adjusting the preset RSSI value, it is possible to adjust the position with respect to the camera that starts/stops parking monitoring. It becomes possible to

(9) Even when the vehicle is parked, the system may have a function of not starting recording while the vehicle is parked until the user of the vehicle moves away from the vehicle beyond a predetermined range.
In this way, it is possible to prevent the user of the vehicle from remaining in the video.

Even when the vehicle is parked, it is preferable to provide a function of starting recording when the user of the vehicle moves away from the vehicle beyond a predetermined range. It is preferable to detect whether or not the user of the vehicle has left the vehicle beyond a predetermined range, and to start recording when it is detected that the user has left the vehicle. Recording may be started by canceling the temporary stop of recording, but it is preferable to start new recording, and when recording video data in a file, it is preferable to generate a new file and start recording.

(10) A driving recording mode, which has a function of recording images captured in the vehicle while the vehicle is running, and is a mode for recording images captured in the vehicle while the vehicle is running; A parking monitoring mode, which is a mode for recording images taken in a vehicle, stops recording in the driving recording mode when it is detected that the vehicle is parked from driving, and the user of the vehicle The system may have a function of not starting recording in the parking monitoring mode of the vehicle until the vehicle is separated from the vehicle by more than a predetermined range. By doing so, it becomes easier to prevent the image of the driver and fellow passengers from remaining in the image when entering the parking monitoring mode.

(11) Equipped with a function of detecting whether or not the vehicle has forgotten to do something that should be done when the vehicle is parked, and transmitting information to that effect, the fourth range, which is a range for detecting separation from the vehicle, is provided. Equipped with a communication function capable of communicating with a terminal that the user can carry in the third range, which is a range that includes a long distance and is close to the vehicle, and forgets to do things that should be done when the vehicle is parked. is detected, the system may be provided with a function of transmitting information to that effect by the communication function.

In this way, when the system detects that the user has forgotten to do something that should be done when the vehicle is parked, the terminal that the user can carry can receive information indicating that fact. . In particular, when the terminal that the user can carry receives the information to that effect, it is preferable to notify that effect.

Items to be done when the vehicle is parked include, for example, turning off the illumination, locking the doors, and turning off the hazard lamps. The information to that effect may be, for example, the state of the items to be done when the vehicle is parked, but it is particularly preferable to use information indicating that the items have been forgotten. For example, the information may be illumination status, door lock status, hazard lamp flashing status, etc. However, information indicating forgetting to turn off the illumination, forgetting to lock the door, or forgetting to turn off the hazard lamp may be used. It is particularly convenient to have a configuration in which the driver is automatically notified of these forgettings.

For example, the system should be a surveillance camera with a Bluetooth communication function, and if the surveillance camera is within the Bluetooth connection range of the smartphone (area-in), the Bluetooth connection is maintained, and the camera periodically sends periodic monitoring notifications. Send a message, etc., and when the smartphone receives this message, acquire the RSSI value at the time of reception. It is preferable to configure such that the instruction message is transmitted in the same way. When the terminal is configured with a smartphone, if the app is in the background, the app itself cannot operate regularly, and if the RSSI value is not read when a message is received, the correct RSSI value cannot be obtained. Although the correct distance is not known, such a problem can be solved by using a configuration in which periodic messages are sent from the camera side. By maintaining the connection with the camera while in the area, it is preferable to configure the camera to transmit information such as the number of recordings and vehicle information when the state of the camera changes. Again, the transmission cycle of the periodic monitoring communication message is 2 seconds. The reason for 2 seconds is the same as the reason for the beacon transmission period. In particular, if it is sent at short intervals, the application cannot be started smoothly, the application will operate frequently, and the battery will be consumed, but this problem can also be solved. By recognizing the distance between the parking monitoring camera and the smartphone in this way, the user can automatically stop the parking monitoring and get into the car without any operation, just by holding the smartphone. can be done. When the user parks the car and leaves the place with the smartphone, the camera can automatically start monitoring the parking. It is preferable to have a configuration in which a Bluetooth connection is automatically established with the camera when approaching the parking surveillance camera, and the information held by the camera can be read out when necessary as long as the Bluetooth connection is established.
A periodic monitoring notification message may be a signal that is neither a beacon nor an advertisement.
(12) It is preferable to provide an adjustment function for adjusting the fourth range by a user's operation.

In this way, the user himself/herself can set how far away from the vehicle the video recording is started. For example, separation may be detected by the strength of the radio wave, and a function may be provided to set the strength of the fourth range by the user's operation. For example, it is preferable to provide an RSSI level setting function. By adjusting the preset RSSI value, it is possible to adjust the position with respect to the camera that starts/stops parking monitoring. It becomes possible to

In particular, both the configuration (11) and the configuration (7) are preferably provided, and the first range and the third range, and the second range and the fourth range are preferably the same range. Also, it is preferable to have both functions (8) and (12).

It would be convenient if criminal acts involving parked vehicles could be deterred and events occurring around the vehicle could be recorded on video. In addition, the vehicle monitoring mode can be turned ON/OFF without the user's own operation. It is even more convenient.

Further, for example, it may be provided with a function of canceling/starting recording while the vehicle is parked based on the passage of time or information detected by various sensors attached to the vehicle. For example, recording may be performed until a predetermined period of time has elapsed since entering the parking monitoring mode, and recording may be stopped after the predetermined period of time has elapsed. Although there is a high possibility that thieves will approach the car after confirming that the user has left the car, such a scene can be accurately recorded and the recording capacity can be reduced. Also, recording may be started when a sensor detects the approach of a person who does not have the terminal of the user. If it becomes possible to record parking surveillance video in this way, it will be possible to more accurately leave evidence of criminal acts, etc., and it will be possible to eliminate the reflection of the user himself, thereby preventing unnecessary recording. An increase in the recording capacity can be reduced, and the recorded contents can be appropriate contents.
The configuration for detecting area-in/area-out is not limited to the case of using a Bluetooth beacon, and may be a configuration using GPS, for example.
(13) For example, it may be configured as a program for causing a computer to implement the functions described in (1) to (11) above.

The inventions shown in (1) to (12) above can be combined arbitrarily. For example, a configuration may be adopted in which at least part of the configuration of at least one of the following inventions (2) is added to all or part of the configuration of the invention shown in (1). In particular, the invention shown in (1) may be added with at least a part of the configuration of at least one invention after (2). Arbitrary configurations may be extracted from the inventions shown in (1) to (12) and the extracted configurations may be combined. The applicant of this application intends to obtain rights to inventions including these configurations. In addition, even if there is a description of "in the case of" or "when", it is not described as a configuration limited to that case or that time. These are examples of better configurations, and we intend to acquire configurations that are not in these cases or occasions. Moreover, the parts described with order are not limited to this order. It also discloses a configuration in which some parts are deleted or the order is changed, and there is an intention to acquire the right.

It is possible to provide systems, programs, and the like that are superior to conventional systems, such as better usability than conventional ones.

The effect of the invention of the present application is not limited to this, and the effect produced by the parts of the configuration disclosed in the specification and drawings, etc. is also disclosed, and the configuration that produces the effect is also acquired by divisional application, amendment, etc. have the intention to For example, in this specification, the description of "can be done" is a description that clearly shows the effect, and there are parts showing the effect even if there is no description of "can be done". Moreover, even without such a description, there is an effect that can be grasped by the configuration.

As an embodiment of the present invention, an example in which the configuration of this system is realized by a drive recorder that can be installed in a vehicle will be described below.

The drive recorder of this embodiment has a camera, an LED for shooting in dark places, and a recording lamp in the camera section, and a microphone, a speaker, a microSD card interface, a REC button, a recording button, a Bluetooth communication module, a WiFi communication module, and an impact in the main body. Equipped with a sensor, tilt sensor, door open sensor, etc., these are connected to the microcomputer that is the control unit, and the CPU built into the microcomputer executes the program stored in the microcomputer to control these, and the following Realize the function of the drive recorder described.

The drive recorder has the function of wirelessly connecting to smartphones and personal computers equipped with these communication functions via Bluetooth modules and WiFi modules to exchange information.

As shown in FIG. 1, the main body of the drive recorder of this embodiment includes a substantially cylindrical main body and a plate-like bracket arranged obliquely on the cylindrical surface of the substantially cylindrical main body. The main body is configured to be rotatable around the axis of. Furthermore, on the bottom side of the main body, there is a camera section which is a rectangular parallelepiped protruding part that is square when viewed from the bottom and whose longitudinal direction is the left and right direction when viewed from each side. It is configured so that the angle range can be adjusted by manipulating a finger within the cutout range of the main body around the axis. The camera section has a camera with a lens on its bottom surface. The angle range in which the camera unit can be adjusted is, for example, 30 degrees on one side and 60 degrees in total in the front-rear direction, based on the posture of facing straight down. The angle of view of the camera mounted on the camera unit is 220 degrees in the vertical plane when the main body is correctly attached to the vehicle 1. - 特許庁As a result, a range wider than a half celestial sphere can be photographed with the lower part as the central axis, so that a 360-degree range can be photographed with the vertical direction as the axis.

A recording lamp is provided at the center of each of the front and rear side surfaces of the camera unit, and a pair of dark place photographing LEDs are provided on the left and right sides of the recording lamp at the same interval. The dark place photographing LED is turned on when an event occurs in a dark place during the proximity monitoring mode, which will be described later. The recording lamp notifies the operating state of the main body by lighting, extinguishing, or blinking of the lamp. Settings are required according to the mounting position.

As shown in FIG. 2( a ), the mounting position may be, for example, the upper part of the windshield of the vehicle, and may be mounted on the driver's seat side or the passenger's seat side with the room mirror in the center in the left-right direction interposed therebetween. can. The direction of the bracket can be attached in any desired direction as shown in FIG. 2(b). When installing on the driver's seat side, the bracket should be on the right side, while when installing on the passenger's seat side, the bracket should be on the right side. Attach the bracket to the windshield with double-sided tape. As shown in Fig. 2(d), the installation direction can be set to either the right side or the left side using dedicated viewer software that runs on a computer or a dedicated application that runs on a smartphone. It is configured. Mounting position information set by the dedicated viewer software or dedicated app is equipped with a function to transfer to the memory of the main unit via Bluetooth connection. Based on the transferred mounting position information, it is controlled which of the recording lamp on the front side of the camera unit and the recording lamp on the rear side of the camera unit is lit. When it is set to the right side, the recording lamp on the front side in FIG. 1 is turned on, while the recording lamp on the back side is not turned on. When it is set to the left side, the recording lamp on the rear side in FIG. 1 is turned on, but the recording lamp on the front side is not turned on. If the recording lamp on the outside of the vehicle is lit while driving, it may be a violation of the Road Traffic Law, but this can be prevented.

To attach the bracket to the windshield, as shown in Fig. 3, attach double-sided tape to the mounting surface of the bracket, remove the nut provided on one side of the main body, and remove the ring portion of the bracket from one side of the main body. Insert and tighten the nut to fix the angle between the bracket and the main body. The mounting structure of this ring to the bracket is a known structure. At this time, after adjusting the angle between the bracket and the main body so that the horizontal line on the other side of the main body is horizontal, tightening the nut and temporarily fixing, as shown in FIG. Peel off the protective film, adjust the angle between the bracket and the main body so that the main body and the ground are horizontal, and tighten the nut to fix it completely. After that, as shown in FIG. 5, the camera section is operated to adjust the angle.

As shown in FIG. 2, the lower surface of the main body is provided with a built-in microphone, which has a function of collecting and recording surrounding sounds. A speaker is provided on the upper surface side of the main body to output operation sounds.

One side surface of the main body is a substantially circular flat surface, on which the microSD card insertion slot, power connector, REC button, and record button are arranged in the positional relationship shown in FIG. 2(c).

You can insert a microSD card into the microSD card slot. It has a function to record and record the video captured by the camera and the audio collected by the microphone on the inserted microSD card. If there are no "NORMAL", "EVGS", and "EVSW" folders in the root directory of the microSD card when the power is turned on, create the "NORMAL", "EVGS", and "EVSW" folders.

The power connector is a connector for connecting the plug of the power cable shown in FIG. The power cable is pulled out in a direction orthogonal to the direction in which the plug of the power cable is inserted. The plug of the power cable is equipped with a power line that is connected to the vehicle's accessory power line, the vehicle's battery power line, and the vehicle's ground line using an electrotap or the like. up to are stored in one covering. The battery power line is configured to be connected to the vehicle's battery power supply via a fuse housed in a fuse holder.

As shown in FIG. 7, recording in the DVR mode is performed when the ACC is on, such as when the vehicle engine is on. Recording in DVR mode includes constant recording and event recording. Continuous recording starts recording when ACC is turned on and ends recording when it is turned off. Recording continues while ACC is on. For constant recording, a file is created every 3 minutes in the "NORMAL" folder, and when the recording capacity is full, the oldest recording file is overwritten and recording continues. The REC button is a button that allows the user to manually input instructions to stop/resume continuous recording. If the REC button is detected to be pressed while the recording is stopped, continuous recording is resumed.

Event recording includes G-sensor recording and one-touch recording. G sensor recording is a function that records when the acceleration detected by the G sensor built into the main unit exceeds a set level such as the impact level equivalent to a collision (when an acceleration event occurs). 10 seconds before the event occurrence and 20 seconds after the event occurrence for a total of 30 seconds. One-touch recording is a function that records when it detects that the record button has been pressed, and creates a recording file for a total of 30 seconds, 10 seconds before the event occurrence and 20 seconds after the event occurrence, in the "EVSW" folder.

As shown in FIGS. 8 to 12, when the ACC of the vehicle is turned off, it shifts to the approach monitoring mode in response to the operation trigger and starts parking monitoring. Parking monitoring recording methods include parking records and event records. As shown in FIG. 8, there are two recording modes, "always" and "event only", and a function for setting which mode to use is provided. "Always" always records, and event recording is performed when any of the impact sensor detects an impact, the tilt sensor detects a change in tilt, or the door open sensor detects a door opening. "Event Only", as shown in FIG. 9, activates the camera when the microwave sensor detects the approach of a person, and then records the event when the approach, impact, tilt, or door opening is detected. The initial value is set to event only. Thereby, power consumption can be suppressed. After the set recording time has elapsed (initial value is 30 minutes), the recording mode is automatically switched to event only, and parking monitoring is continued. Parking recording is performed by reducing the number of frames from the initial value of 5 frames/second and the initial value of 30 frames/second for constant recording when ACC is on. The recording lamp flashes red during event recording. Only when the inclination and the door opening are detected, the warning sound "beep-beep..." is sounded from the speaker for 20 seconds.

As shown in FIGS. 10 and 11, there are three types of operation triggers in the parking monitoring mode: manual, which is the initial value, ACCOFF interlocking, and area AUTO. It has a function to set

When the operation trigger is set to manual, as shown in the lower part of Fig. 11, when the vehicle engine is turned off and the ACC is turned off, the speaker will say, "Press the REC button to shift to approach monitoring mode." output audio from When 15 seconds have passed since this voice output is complete, the power will be turned off, and if the REC button is pressed within 15 seconds, a voice will be heard saying "Transition to approach monitoring mode". is output from the speaker, and parking monitoring recording in the approach monitoring mode is started after the set transition time to the approach monitoring mode (initial value is 3 minutes) has elapsed.

When the operation trigger is set to interlock with ACCOFF, as shown in the upper part of Fig. 12, when the engine of the vehicle is turned off and the ACC is turned off, a voice saying "Transition to approach monitoring mode" is heard from the speaker. After the set transition time to approach monitoring mode (initial value is 3 minutes) has elapsed, parking monitoring recording in approach monitoring mode is started.

When the operation trigger is set to area AUTO, as shown in the lower part of FIG. 12, it is determined whether there is a smartphone paired with Bluetooth. In that case, the speaker will output a voice saying "Move to proximity monitoring mode." When it becomes, the parking monitoring recording in approach monitoring mode is started.
Bluetooth pairing is performed as shown in FIGS. 13 to 15. FIG.

Bluetooth pairing is performed in the setting mode of the drive recorder as shown in FIGS. The setting mode is entered when the simultaneous pressing of the REC button and the recording button is detected after the pressing of the REC button is detected in a state in which the engine of the vehicle is turned on and continuous recording is started. When the setting mode is entered, a voice saying "This is the setting mode, please press the REC button" is output from the speaker. If the press of the REC button is detected within 15 seconds after the output of this voice is completed, the voice "SD card format, please press the REC button" is output from the speaker. If the REC button is detected to be pressed within 15 seconds after the completion of this output, the microSD card is formatted. On the other hand, if the press of the record button is detected within 15 seconds, a voice saying "Bluetooth pairing. Please press the REC button" is output from the speaker. If the press of the REC button is detected within 15 seconds after this output is completed, a voice saying "Start Bluetooth pairing. Please press the REC button again" is output from the speaker. If the press of the REC button is detected within 15 seconds after the completion of this audio output, Bluetooth bearing is started.

The smartphone performs user operations and application processing as shown in FIG. 15 . First, turn on Bluetooth on your smartphone. Start the app "SQ Remote" from the smartphone launcher. When activated, a "reconnect" button is displayed on the screen of the smartphone. When a tap of the "reconnect" button is detected, a Bluetooth pairing request dialog is displayed. This dialog displays the device name of the drive recorder, a pairing button, and a back button. When the tap of the pairing button is detected, pairing with the drive recorder with the displayed device name is performed. When the pairing is successful, the voice "Pairing was successful" is output from the smartphone's speaker, and the operation screen is displayed.

The proximity monitoring mode operation screen has the screen configuration shown in FIG. 16 and has the functions shown in FIG. As shown in FIG. 16, the proximity monitoring mode operation screen includes, from the top to the bottom of the screen, an operating state display area, a vehicle battery voltage display area, an area sensitivity level display area, an event record number display area, and a recording mode switch. It has an area and stop button, an area sensitivity setting button, a version information button, a recorder connection button, and a smartphone image display button.

The operation status display area displays an operation trigger, recording, event monitoring, monitoring, stop, cancel area, event recording NG, and the like. The vehicle battery voltage display area displays the vehicle battery voltage. The area sensitivity of area AUTO is displayed in the area sensitivity level display area. The number of event records in the approach monitoring mode is displayed in the event record number display area. The recording mode switching area has a constant button and an event only button, and has a function of switching the recording mode according to the user's operation as shown in FIG. The stop button stops parking monitoring when operated by the user as shown in FIG. The area sensitivity setting button sets the area sensitivity of area AUTO. As shown in FIG. 20, when a touch on the area sensitivity setting button is detected, an area sensitivity setting screen is displayed. As shown in FIG. 20(b), the area sensitivity setting screen includes, from top to bottom, a title area, a sensitivity level display area, a sensitivity level image display area, a sensitivity level slider area, and an enter button. The title area displays the title "area sensitivity". In the sensitivity level display area, the sensitivity value indicated by the slider of the slider bar displayed in the current sensitivity level slider area is displayed to the right of the letters "sensitivity level". Depending on the position of the slider of the slider bar displayed in the sensitivity level slider area, the sensitivity level can be moved and set within a range of 1 at the left end to 10 at the right end. The example of FIG. 20(b) shows a state where the sensitivity level is "7". In the sensitivity level image display area, an image from the top of the car is displayed, and a semi-transparent light blue circle with a diameter exceeding the length of the car in the left-right direction is displayed centering on the center of the image from the top of the car. ing. This diameter is shown changing according to the value of the current sensitivity level of the slider. The example of FIG. 20(b) shows the state of sensitivity level "7", and the example of FIG. 21 shows the states of sensitivity level 2, sensitivity level 6, and sensitivity level 10 from left to right. ing. When the touch of the decision button is detected, the sensitivity level set by the slider is saved as the setting value, and the RSSI value corresponding to the radius of 1m per sensitivity level is set as the RSSI setting value, and the proximity monitoring mode operation screen is displayed. return. For example, if the sensitivity level is 10, the RSSI value corresponding to a radius of 10 m is set as the RSSI set value. The default value of the sensitivity level slider is a sensitivity level of 6 and an RSSI set value corresponding to a radius of 6 m. The RSSI value for each sensitivity level is a value measured in advance every 1 m and is used as the RSSI set value.

When the drive recorder is within the smartphone's Bluetooth connection range (here, referred to as area-in), the drive recorder maintains the Bluetooth connection and periodically sends periodic monitoring messages from the drive recorder. When the smartphone receives this message, it acquires the RSSI value at the time of reception, and when the RSSI value falls below the set value, the smartphone determines that the area is out and transmits an instruction message to the drive recorder to perform parking monitoring. When the drive recorder receives this instruction message, it enters the parking monitoring mode and starts parking monitoring recording.

By sending a regular monitoring message from the camera side in this way, even when this app on the smartphone is in the background, the app can be called from the OS by this regular monitoring message and can be operated. Also, by reading the RSSI value when the message is received, the correct RSSI value can be obtained, making it possible to obtain the correct distance to the drive recorder.

While in the area, the connection between the drive recorder and the smartphone is maintained, and when the status of the drive recorder changes, the values of the items described with reference to FIG. The value of the item is received and the screen display of the smart phone in FIG. 16 is updated.

FIG. 22 is a diagram schematically showing the operation of the smartphone application and the drive recorder when the user holding the smartphone gets out of the vehicle and moves away (at the time of leaving). The connectable range of Bluetooth is the outer circle, and the connectable range is about ten and several meters. The inside of the inner circle is the range where the RSSI value exceeds the RSSI setting value. After the ACC is turned off, the processing for separation shown in FIG. 22 is performed. Start monitoring process of RSSI value of periodical monitoring message. In the RSSI value monitoring process, when the RSSI value of the periodical monitoring message exceeds the RSSI set value, the status is set to "monitoring waiting". When the RSSI value of the periodical monitoring message exceeds the RSSI set value, the drive recorder does not record. In the range within the inner circle, the display of the operating state display area of the proximity monitoring mode operation screen of the smartphone application is processed to be "waiting for monitoring" as shown on the lower right side of FIG. 22 .

Then, when the user moves further away from the vehicle and the RSSI value of the periodic monitoring message becomes equal to or less than the RSSI set value, the smartphone transmits a parking monitoring recording start instruction signal to the drive recorder via Bluetooth. The drive recorder that has received the parking monitoring recording start instruction starts parking monitoring in the parking monitoring mode and starts recording. In the range between the inner circle and the outer circle in FIG. 22, which is the RSSI value of the periodic monitoring message that is less than or equal to the RSSI set value and is the Bluetooth connectable range, the smartphone application displays the proximity monitoring mode operation screen. 22, the display of the operating state display area is changed to "event monitoring" as shown in the lower center of FIG.

When the user further moves away from the vehicle and goes out of the Bluetooth connectable range, the smartphone app changes the display of the operation status display area of the proximity monitoring mode operation screen to "-" as shown on the lower left side of Fig. 22. process. When the smartphone is out of the Bluetooth connectable range and the Bluetooth communication is disconnected, the drive recorder starts the process of periodically transmitting the Bluetooth beacon signal.

Next, the operation when the user carrying the smartphone returns to the car will be described with reference to FIG. 23 . FIG. 23 is a schematic diagram similar to the description of FIG. 22, and shows the operation when the user is heading toward the car, contrary to FIG. Outside the Bluetooth connectable range, the drive recorder periodically transmits Bluetooth beacon signals. Outside the Bluetooth connectable range, the display of the operating state display area of the proximity monitoring mode operation screen remains displayed as "-" as shown in the lower left part of FIG.

When the smartphone enters the Bluetooth connectable range and receives a Bluetooth beacon signal, it establishes a Bluetooth connection with the drive recorder, the drive recorder starts processing to periodically send periodic monitoring notification messages, and the drive recorder Start monitoring processing to see if the RSSI value of this periodic monitoring notification message exceeds the set value.

When the user approaches the vehicle and the RSSI value of the periodic monitoring message exceeds the RSSI set value, the smartphone transmits a parking monitoring recording stop instruction signal to the drive recorder via Bluetooth. The drive recorder that has received the instruction to stop parking monitoring recording stops parking monitoring in the parking monitoring mode and stops recording.

In the range between the inner circle and the outer circle in FIG. 23, which is the RSSI value below the RSSI setting value and is the Bluetooth connectable range, the display of the operation state display area of the proximity monitoring mode operation screen is changed to that of FIG. As shown in the center of the lower row, the process of "event monitoring" is performed. In the range within the inner circle, the display of the operating state display area of the proximity monitoring mode operation screen of the smartphone application is processed to be "waiting for monitoring" as shown on the lower right side of FIG. 22 . While the drive recorder is connected to the smartphone, the connection is maintained. When the status of the drive recorder changes, the drive recorder transmits the values of the items described with reference to FIG. Since the value of the item is received and the screen display of the smartphone in FIG. 16 is updated, the display is updated as can be seen by comparing the lower center and the lower right side of FIG. 22 . For example, in the event record number display area, 0 is displayed in the center of the lower row, and 1 is displayed in the right lower row, where a file is generated by stopping recording.

It should be noted that the transmission cycle of the periodic monitoring message and the Bluetooth beacon is 2 seconds. By doing so, it is possible to suppress the consumption of the battery of the smartphone, and when the user carrying the smartphone moves away from the drive recorder, it is possible to determine the area by moving about 3 or 4 steps. Also, if periodic monitoring messages are sent at particularly short intervals, the smartphone application will not be able to start smoothly, and the application will run frequently, which will increase battery consumption, but this can also be suppressed.

The drive recorder of the present embodiment described above is an example of a system having a function of recording images taken in the vehicle while the vehicle is parked, and has a function of detecting the approach of the vehicle user to the vehicle. , has a function to cancel recording while the vehicle is parked when it detects that the vehicle user is approaching the vehicle. Therefore, the recording can be canceled only by the user approaching the parked vehicle, and a system that is more user-friendly than the conventional system can be realized. For example, when a user approaches a vehicle, if the vehicle user appears in the video captured by the parking surveillance camera, the video will be useless, and the recording area of the microSD card will be wasted. However, in this way, waste can be reduced. For example, as the approach, the approach is such that it is possible to recognize that the user is getting into a car. When you get in the car, if you are reflected in the parking surveillance video of the drive recorder, it will leave useless video, and the video recording area such as the microSD card will be wasted. , can reduce waste.

As the vehicle, in the present embodiment, a four-wheeled automobile is explained, but for example, a bicycle or a motorcycle may be used. Further, in the present embodiment, the vehicle is assumed to be a private car, but it may be a company car or a passenger vehicle such as a bus or a taxi.

In this embodiment, in order to detect that the vehicle engine and electric vehicle are turned off while the vehicle is parked, the connections shown in FIG. 6 are made to detect that the ACC is turned off. may be detected by other methods. For example, an image of the inside of the vehicle captured by the camera of the drive recorder may be image-recognized, and if a state in which no one is present is detected, it may be determined that the vehicle is parked. In addition, for example, the system is operated by receiving power supply from a separate power supply such as a connection to a car battery or a battery different from the car battery, and monitoring the power supply from the cigarette lighter socket to monitor the power supply from the cigarette lighter socket. If there is no power supply, it may be determined that the vehicle engine or the electric vehicle is turned off.

In this embodiment, the user is mainly assumed to be the driver, but the user may also be a fellow passenger. Whether or not the user is the user may be determined, for example, based on whether or not an image similar to an image of a user registered in advance has been captured.

In this embodiment, it is assumed that the driver is not in the vehicle when the vehicle is parked. good. In this embodiment, the function to detect whether or not the driver is not in the vehicle is detected by the RSSI level of the radio waves emitted by the drive recorder received by the smartphone owned by the driver. It is preferable to make a determination based on whether or not there is a pre-registered driver of the vehicle in the video imaged in the vehicle.

In this embodiment, the camera of the drive recorder installed in the passenger compartment of the vehicle is used for imaging, and a substantially semi-spherical camera is used. A wide-angle camera may also be used. The imaging direction may be, for example, the inside of the vehicle or the direction from inside the vehicle to outside the vehicle. In particular, it is preferable to adopt a configuration that allows photographing both inside and outside the vehicle. As such a configuration, for example, imaging is performed by two cameras, one for inside the vehicle and one for outside the vehicle, or a configuration in which one half-sphere camera is installed facing downward from the ceiling inside the vehicle. should be

In this embodiment, the video signal of the video shot by the camera is compressed and recorded in the microSD card as digital information, but it may be recorded in analog form.

In this embodiment, a microSD card is inserted into the main body of the drive recorder for recording. can be The recording unit may be provided in the vehicle, or may be provided in a server or the like connected by communication. The recording unit is preferably a detachable recording medium. The recording unit may be a non-volatile memory. The recording unit is preferably a semiconductor memory. It is particularly preferable that the recording means is a card-shaped recording medium. It is particularly preferable to use a card-like medium as the recording unit.

In the present embodiment, recording is performed as a file for each predetermined time unit, but video data may simply be recorded continuously, for example. Also, the recording may be terminated when a specific termination condition is satisfied instead of the time unit.

The drive recorder may be configured with one housing, or may be configured with a plurality of housings and electrically connecting the plurality of housings by wire or wirelessly. A part of the function of the drive recorder of this embodiment may be outside the vehicle. For example, part of the system may be configured as a server, but it is preferable to configure the vehicle so that all the functions of the drive recorder are provided in the vehicle, as in the present embodiment.

In this embodiment, when the user of the vehicle approaches the vehicle, the recording of the image taken in the vehicle is stopped and the file being recorded is closed. good too.

The approach of the vehicle user to the vehicle may be detected by, for example, detecting that the vehicle door has been opened by the user. The detection of the approach to the vehicle may be performed based on whether or not the user of the vehicle is within a predetermined range outside the door of the vehicle. In this way, the recording while the vehicle is parked is stopped only by the user of the vehicle approaching within a predetermined range outside the door of the vehicle.

In the present embodiment, detection of the approach of the vehicle user to the vehicle is performed based on the radio wave state of a smart phone, which is a terminal that the user can carry. Thereby, approach can be detected more reliably. For example, the approach can be detected more reliably than the recognition of the user by the recognition of the captured image. In addition, for example, the user can detect the terminal without taking it out of the storage location such as a bag or pocket one by one.

A smartphone that a user can carry is battery-powered. Although the terminal is a smartphone in this embodiment, it may be a remote control, a key, a tag, or the like. But it's best with a smartphone. This is because there is a high possibility that the user of the vehicle will also take the smartphone out of the vehicle.

As radio waves, Bluetooth is used in this embodiment, but other radio waves may be used. For example, LTE may be used, but it is particularly preferable to use one with a communication distance of several meters to ten and several meters. It is particularly preferable to use a beacon, and it is particularly preferable to use a Bluetooth beacon as in this embodiment.

As a configuration based on the radio wave state, for example, it may be possible to detect approaching the vehicle when the drive recorder is ready to receive radio waves from the smartphone, but for example, wireless communication with the drive recorder is possible. It is preferable that the approach to the vehicle is detected when the state is reached.

However, it is particularly good if it is like this embodiment. In the present embodiment, detection of the approach of the vehicle user to the vehicle is performed based on the strength of radio waves used for communication with a smartphone, which is a terminal that the vehicle user can carry. There is no need to provide a radio wave transmitter and receiver for distance detection, which are separate from the radio wave transmitter and receiver used.

Regarding the detection of approaching the vehicle, the reception strength of the radio waves emitted by the drive recorder is measured by a smartphone, which is a terminal that the user can carry, and the measured reception strength is transmitted to the drive recorder and received by the drive recorder. If the reception intensity exceeds a predetermined intensity, it may be assumed that the approach to the vehicle is detected. By doing so, it is possible to suppress the consumption of the battery of the terminal that the user can carry. These predetermined states may be, for example, when the received signal strength is equal to or greater than a predetermined level.

To detect the approach of a vehicle user to a vehicle, the drive recorder emits a radio wave whose strength can be measured by a smartphone, which is a terminal that the vehicle user can carry, at predetermined intervals, and the vehicle user can carry it. A smart phone, which is a smart device, measures the intensity of radio waves emitted from the drive recorder at a predetermined cycle, and transmits information on the measurement results to the drive recorder, which then detects approaching based on the information on the measurement results. You can also use In this way, battery consumption of the smart phone can be suppressed. Compared to a vehicle, the battery capacity of a smartphone is extremely small, and transmission often consumes much more power than reception. Electricity can be reduced.

The best way is to measure the intensity of the radio wave transmitted from the drive recorder side at a predetermined cycle by using a smartphone, which is a terminal that the vehicle user can carry, as in the present embodiment, and If the intensity is greater than or equal to the intensity, the information about the measurement result is transmitted, and the drive recorder receives the information about the measurement result and determines that it has approached. In this way, the power consumption of the terminal can be greatly reduced, and the battery driving time of the terminal can be extended.

The predetermined cycle is at least once during the time from when the user approaches the vehicle on foot and the terminal enters the area where radio waves transmitted from the system can be received until the user arrives at the vehicle. An interval that allows reception is desirable, and an interval that allows reception at least several times is particularly desirable. The predetermined cycle is preferably set to a time shorter than the time required for a person to walk several steps. The predetermined cycle may be, for example, 3 seconds or less. On the other hand, if the predetermined period is too short, problems arise. The predetermined time is preferably set to a time longer than or equal to the time during which battery consumption of the terminal can be suppressed. In addition, the inventor found a problem that, when the terminal has an application execution function, the operation of the application does not proceed smoothly if there are frequent reception events. Therefore, it is preferable to set the time longer than the time that does not affect the operation of the application. Taking all of these together, it is best that the predetermined period is approximately 2 seconds as in this embodiment. In this way, it is possible to further reduce battery consumption of the terminal, and other programs such as applications can be operated smoothly, and when the user approaches the vehicle, an appropriate proximity relationship can be established. You can then cancel the recording. For example, if the terminal is a smartphone and the system is configured as a camera, when the user walks and approaches the camera equipped with a beacon, the smartphone will frequently receive signals, so the battery consumption of the smartphone should be reduced. It is preferable that the area can be determined by moving about 3 or 4 steps. Also, if beacons are sent at short time intervals, the smartphone will receive all the beacon signals, so reception events will occur frequently and the application will not operate smoothly. Then, such problems can be suppressed.

The information about the measurement results should be the reception level, and the recording should be canceled when a predetermined condition is met, such as when the reception level received by the drive recorder exceeds a predetermined value. is preferably a signal requesting to stop recording, as in this embodiment. When the strength of the radio wave measured by the smartphone is equal to or greater than a predetermined value, the smartphone transmits a signal requesting to stop recording, and the drive recorder Then stop recording when this signal is received. By doing so, it is possible to further suppress the consumption of the battery of the terminal.
The radio wave may be a beacon signal as in this embodiment. The radio wave may be an advertising signal, like the Bluetooth beacon of this embodiment.

In this embodiment, as an example of a terminal possessed by a user, a smart phone has been described, but a tablet or other terminal may be used. However, smartphones are especially good.

The drive recorder of this embodiment is an example of a parking surveillance camera equipped with a function capable of transmitting a beacon, and the terminal is a smartphone capable of executing an application equipped with a function capable of receiving beacon signals transmitted from the camera. For example, a Bluetooth beacon signal is periodically sent from the camera (every 2 seconds for the product), and when a person holding a smartphone with a special app installed approaches the parking surveillance camera, the smartphone app receives the Bluetooth beacon signal. Then, connect to the camera via Bluetooth, and every time it periodically receives a periodic monitoring notification message from the camera, it acquires the RSSI value and detects the approximate distance to the camera. When the RSSI value reaches or exceeds the preset RSSI value, the parking monitoring operation of the camera can be canceled by making a Bluetooth connection with the camera and stopping the parking monitoring mode.

The Bluetooth beacon should be advertised on the camera side, and a UUID (Universally Unique Identifier) dedicated to the beacon should be created and periodically transmitted.

As a Bluetooth beacon, it is good to transmit ID information called an advertisement packet from the beacon.

The configured ID information may be transmitted periodically. The proximityUUID, Major, and Minor identifiers can be determined arbitrarily, but for example, the proximityUUID should be a common ID for all systems, and the Major and Minor codes should be different for each individual system. In this way, even when a plurality of systems are nearby, video recording can be canceled or started (to be described later) only when a specific system is approached. Then, when pairing the major code and minor code with the camera and the smartphone app, it is better to receive them as message data. If the app knows that the user has re-paired or unpaired, this Major/Minor code should be updated or cleared.

In addition, in the present embodiment, a function is provided for receiving, via wireless communication, an operation signal of a smartphone, which is a terminal that the user of the vehicle can carry. , the drive recorder has a function to stop recording while the vehicle is parked when it receives an operation to stop recording while the vehicle is parked, and when it detects that the user of the vehicle is approaching the vehicle , the drive recorder stops recording while the vehicle is parked even if it does not receive an operation to stop recording while the vehicle is parked.

This eliminates the need for the user to stop recording while the vehicle is parked by taking out the smartphone that the user has when approaching the car. Therefore, troublesome operation when getting into the car is eliminated.

In this embodiment, communication with a terminal that the user can carry in a first range that is a range that includes a range that is farther than the second range that is a range for detecting approaching to the vehicle and is in the vicinity of the vehicle. It has a communication function capable of transmitting information about the situation detected while the vehicle is parked in the first range. Therefore, the terminal that the user can carry can acquire information about the situation detected while the vehicle is parked when the vehicle approaches within the first range, and the user approaches the vehicle beyond the first range. Recording is stopped while the vehicle is parked in the second range. In particular, the terminal that the user can carry has the function of receiving and notifying information about the situation detected while the vehicle is parked from the system. Information about the situation detected while the vehicle is parked can be obtained, and recording while the vehicle is parked is stopped in a second range closer to the vehicle than in the first range. If the user only approaches the first range but does not enter the second range, it is possible to simply obtain information about the situation detected while the vehicle is parked without canceling the recording. For example, if an abnormality is not reported, the user does not approach the vehicle any more, or leaves the vehicle to do some work.

The situation detected while the vehicle is parked may be, for example, a recognition result such as the state of a suspicious person appearing in the captured image. In preparation, the situation detected while the vehicle is parked is used as the acquired information related to the state of the vehicle. The function of acquiring the state of the vehicle may be implemented by providing a sensor or the like in the system, or may be implemented by acquiring from an in-vehicle LAN or the like that the vehicle originally has. The information about the situation detected while the vehicle is parked is preferably information about an abnormality of the vehicle. In this way, it is possible to immediately check whether there is an abnormality in the vehicle when approaching the vehicle under parking monitoring.

Battery information and tire pressure information may be provided as the information about the situation detected while the vehicle is parked. In this way, when approaching a parked car, the battery information, tire pressure, etc. can be checked each time.

The first range may be a communication range provided with a communication function, particularly a range of about ten and several meters. The second range is preferably about 6 m, for example. Since people walk at various speeds, if the distance is too short, drivers and others will be reflected in the parking surveillance video, so this level increases the possibility of not being reflected. Also, for example, when the driver approaches the car, the Bluetooth connection is made and the RSSI is checked every 2 seconds. By the way, about 6m is desirable.

It is preferable to provide an adjustment function for adjusting the second range by a user's operation as in the present embodiment. In this way, the user himself/herself can set how close to the vehicle the video recording is to be canceled. For example, it is preferable to have a configuration in which approach is detected by the intensity of radio waves, and to have a function of setting the intensity of the second range by user's operation. For example, it is preferable to provide an RSSI level setting function. By adjusting the preset RSSI value, it is possible to adjust the position with respect to the camera that starts/stops parking monitoring. It becomes possible to

As in the present embodiment, even if the vehicle is parked, the drive recorder has a function that does not start recording while the vehicle is parked until the user of the vehicle moves away from the vehicle beyond a predetermined range. good. In this way, it is possible to prevent the user of the vehicle from remaining in the video.

Further, as in the present embodiment, it is preferable to provide a function of starting recording when the user of the vehicle moves away from the vehicle beyond a predetermined range even while the vehicle is parked. It is preferable to detect whether or not the user of the vehicle has left the vehicle beyond a predetermined range, and to start recording when it is detected that the user has left the vehicle. Recording may be started by canceling the temporary stop of recording, but it is preferable to start new recording, and when recording video data in a file, it is preferable to generate a new file and start recording.

As in the present embodiment, a running recording mode, which has a function of recording images captured in the vehicle while the vehicle is running and is a mode for recording images captured in the vehicle while the vehicle is running, and a recording mode of the vehicle. A parking monitoring mode, which is a mode for recording images captured by the vehicle while the vehicle is parked, stops recording in the driving recording mode when it is detected that the vehicle has changed from driving to being parked, and The drive recorder may have a function of not starting recording in the vehicle parking monitoring mode until the user of the vehicle moves away from the vehicle beyond a predetermined range. By doing so, it becomes easier to prevent the image of the driver and fellow passengers from remaining in the image when entering the parking monitoring mode.

In particular, as in the present embodiment, parking monitoring recording does not start until the driver with the smartphone leaves the car beyond a predetermined range, and parking monitoring recording starts when the driver moves beyond the predetermined range. Parking surveillance recording should be stopped when the driver approaches the car.

In addition, the drive recorder has a function of detecting whether or not the driver forgets to do something that should be done when the vehicle is parked, and transmits information to that effect. Equipped with a communication function capable of communicating with a terminal that the user can carry in the third range, which is a range that includes a distance beyond the range and is in the vicinity of the vehicle, and forgets to do things that should be done when the vehicle is parked. It is preferable to have a function of transmitting information indicating the fact by the communication function when it is detected that the In this way, when the drive recorder detects that the user has forgotten to do something that should be done when the vehicle is parked, the smartphone or the like that the user can carry can receive information indicating that fact. can be done. In particular, when the smartphone that the user can carry receives the information to that effect, it is preferable to notify that effect.

Items to be done when the vehicle is parked include, for example, turning off the illumination, locking the doors, and turning off the hazard lamps. The information to that effect may be, for example, the state of the items to be done when the vehicle is parked, but it is particularly preferable to use information indicating that the items have been forgotten. For example, the information may be illumination status, door lock status, hazard lamp flashing status, etc. However, information indicating forgetting to turn off the illumination, forgetting to lock the door, or forgetting to turn off the hazard lamp may be used. It is particularly convenient to obtain such information from the OBD connector or the like of the vehicle or to obtain it directly from a sensor or the like, and automatically notify the driver of the forgetting to do so.

For example, the system should be a surveillance camera with a Bluetooth communication function, and if the surveillance camera is within the Bluetooth connection range of the smartphone (area-in), the Bluetooth connection is maintained, and the camera periodically sends periodic monitoring notifications. Send a message, etc., and when the smartphone receives this message, acquire the RSSI value at the time of reception. It is preferable to configure such that the instruction message is transmitted in the same way. When the terminal is configured with a smartphone, if the app is in the background, the app itself cannot operate regularly, and if the RSSI value is not read when a message is received, the correct RSSI value cannot be obtained. Although the correct distance is not known, such a problem can be solved by using a configuration in which periodic messages are sent from the camera side. By maintaining the connection with the camera while in the area, it is preferable to configure the camera to transmit information such as the number of recordings and vehicle information when the state of the camera changes. Again, the transmission cycle of the periodic monitoring communication message is 2 seconds. The reason for 2 seconds is the same as the reason for the beacon transmission period. In particular, if it is sent at short intervals, the application cannot be started smoothly, the application will operate frequently, and the battery will be consumed, but this problem can also be solved. By recognizing the distance between the parking monitoring camera and the smartphone in this way, the user can automatically stop the parking monitoring and get into the car without any operation, just by holding the smartphone. can be done. When the user parks the car and leaves the place with the smartphone, the camera can automatically start monitoring the parking. It is preferable to have a configuration in which a Bluetooth connection is automatically established with the camera when approaching the parking surveillance camera, and the information held by the camera can be read out when necessary as long as the Bluetooth connection is established. A periodic monitoring notification message may be a signal that is neither a beacon nor an advertisement. Moreover, it is preferable to provide an adjustment function for adjusting the fourth range by a user's operation as in the present embodiment. In this way, the user himself/herself can set how far away from the vehicle the video recording is started. For example, separation may be detected by the strength of the radio wave, and a function may be provided to set the strength of the fourth range by the user's operation. For example, it is preferable to provide an RSSI level setting function. By adjusting the preset RSSI value, it is possible to adjust the position with respect to the camera that starts/stops parking monitoring. It becomes possible to In this embodiment, the first range and the third range, and the second range and the fourth range are respectively the same range, but they may be different ranges.

It would be convenient if a parked vehicle could be deterred from committing a criminal act, or if an image of what happened around the vehicle could be recorded. It would be more convenient if the switch could be turned ON/OFF without the switch.

Further, for example, it may be provided with a function of canceling/starting recording while the vehicle is parked based on the passage of time or information detected by various sensors attached to the vehicle. For example, recording may be performed until a predetermined period of time has elapsed since entering the parking monitoring mode, and recording may be stopped after the predetermined period of time has elapsed. Although there is a high possibility that thieves will approach the car after confirming that the user has left the car, such a scene can be accurately recorded and the recording capacity can be reduced. Also, recording may be started when a sensor detects the approach of a person who does not have the terminal of the user. If it becomes possible to record parking surveillance video in this way, it will be possible to more accurately leave evidence of criminal acts, etc., and it will be possible to eliminate the reflection of the user himself, thereby preventing unnecessary recording. An increase in the recording capacity can be reduced, and the recorded contents can be appropriate contents.
The configuration for detecting area-in/area-out is not limited to the case of using a Bluetooth beacon, and may be a configuration using GPS, for example.
