Description

  The present invention relates to a system, a program, and the like.

  For example, a system such as a drive recorder that can be mounted on a vehicle or the like can provide information (for example, video) useful for verification of an abnormal situation such as an accident, and a drive recorder as an example is patented. It is disclosed in Document 1. Such a system can be used not only for transportation vehicles (for example, trucks, forklifts, etc.), business vehicles (for example, taxis, buses, etc.) and general vehicles, but also for further versatility. Expected.

  For example, the drive recorder described in Patent Document 1 includes an imaging unit, a storage unit, and an acceleration sensor. When the vehicle is suddenly braked or a collision occurs, causing the acceleration to exceed a predetermined level, the drive recorder triggers the generation of the acceleration and stores the images taken for a predetermined time before and after the generation of the acceleration in the storage unit. To do. The captured image is used by an insurance company or the like to grasp the situation of the accident.

JP 2012-3408 A

  However, when an image is stored triggered by the occurrence of an acceleration of a predetermined level or more as in the drive recorder described in Patent Document 1, the image is displayed even though an abnormal situation such as an accident does not actually occur. Is stored in many cases, which is a cause of increasing the verification load (for example, verification load by an insurance company) of an abnormal situation. That is, for example, a large acceleration occurs due to sudden braking, sudden acceleration, sudden steering, a road step, and the like, and it is necessary to find a useful image from a large number of images unrelated to an abnormal situation.

  Therefore, an object of the present invention is to provide, for example, a system, a program, and the like that can reduce the load of verification of an abnormal situation.

  The object of the invention of the present application is not limited to this, and there is an intention to acquire the right by a divisional application, amendment, etc. for a configuration aiming to obtain an effect obtained from the configuration portion disclosed in the present specification and drawings. . For example, in the present specification, a subject is disclosed in which a part described as "to be made", "to be possible" or the like in the present specification is replaced with "to be a task". The issues are described as being independent of each other, and the organization for solving the issues is also willing to acquire the right by divisional application / correction etc. alone. Even if the problem is implicitly grasped from the description of the specification, the applicant intends to make a part of the configuration described in the present specification as a claim in the amendment or divisional application. Moreover, the subject which combined these independent subjects is also disclosed.

(1) A control means having a function of recording a captured image in a predetermined recording area triggered by establishment of a specific condition that can be satisfied at a lower frequency than when a predetermined acceleration or more occurs. And a system that can be mounted on a vehicle.

  According to this, since the number of images to be recorded is smaller than when a predetermined acceleration or more is generated, it is possible to reduce the verification load of the abnormal situation.

  Note that "when acceleration above a predetermined level is generated" may be, for example, when the range of acceleration generated when a vehicle or the like normally travels is exceeded. For example, when a vehicle or the like is traveling normally, the acceleration often fluctuates within a normal range although there is a slight vertical width. However, for example, when a vehicle or the like rides on a step, or at the time of a sudden braking, the acceleration may rise temporarily (for example, momentarily). In such a case, it may be determined that a predetermined or higher acceleration has occurred.

  In particular, it is preferable to have a function of recording an image captured when acceleration of a predetermined level or more occurs (here, referred to as an acceleration event recording function). The function of recording a captured image in a predetermined recording area triggered by the establishment of the condition of (3) can be established at a lower frequency than "acceleration above a predetermined value" which is the recording condition in this acceleration event recording function. It is particularly preferable to use a function for recording an image captured when a specific condition is satisfied in a predetermined recording area. In addition, “acceleration above predetermined level”, which is the recording condition by the acceleration event recording function, should be configured to be settable based on the instruction of the user etc. Especially in this case, from the acceleration which is the default setting in the setting. It is particularly preferable to have a function of recording an image captured in a predetermined recording area, triggered by the establishment of a specific condition that can be established at a low frequency. More preferably, it is preferable to have a function of recording an image captured in a predetermined recording area, triggered by the establishment of a specific condition that can be established less frequently than the largest acceleration that can be set.

  The "system" may be a system mounted on an object other than a vehicle. In the example of an object other than a vehicle, for example, a system mounted on a ship or an airplane may be used, but in particular, a system mounted on a vehicle is preferable. Further, the "system" may be a so-called drive recorder that records an image such as the moment of a traffic accident.

  The “image” may be a still image or a moving image. The moving image may be, for example, a moving image obtained by continuously displaying a series of images taken at constant time intervals at short intervals, or may be a completely continuous image. .

  The "acceleration" may be detected by, for example, an acceleration sensor. The “when acceleration occurs” is particularly preferably when the acceleration exceeds a predetermined value. The predetermined value may be set, may be a positive value, or may be a negative value. However, it is preferable to set acceleration to occur, for example, when an object such as a vehicle receives an external impact, and in particular to set the level of acceleration that may occur when an accident occurs. The level of acceleration that can be generated when the

  The "predetermined recording area" may be, for example, a storage element such as a RAM or a storage medium such as a memory card, but if a recording speed is required, a storage element such as a RAM It is preferable that Also, these storage areas may be provided in the system or may be provided outside the system.

  Recording on a predetermined recording area may be, for example, continuous recording in which images are continuously recorded, or event recording in which images are recorded at predetermined times before and after a specific condition is established. Good. It is preferable to provide a function for performing both continuous recording and event recording. For example, continuous recording and event recording may be recorded in different recording areas.

  Examples of images recorded in a predetermined recording area include an accident of contact between objects such as a vehicle, an accident of contact of an object such as a vehicle with a person or an animal, an accident of contact of an object such as a vehicle with a structure, etc. For example, it is possible to cite an image in which an abnormal situation such as a meteor fall, an accident associated with a natural disaster such as an earthquake, or the like may appear in addition to a traffic accident.

  As the “specific condition”, for example, a condition indicating that there is a high possibility that an abnormal situation has occurred in an object such as a vehicle on which the system is mounted, or an abnormality in an object different from an object such as a vehicle on which the system is mounted. A condition indicating that there is a high possibility that a situation has occurred can be mentioned.

  As the "abnormal situation", for example, traffic accidents, accidents associated with natural disasters such as floods, earthquakes, falling of meteorites and the like of objects such as vehicles can be mentioned. In addition, traffic accidents in an “abnormal situation” include, for example, a collision accident between objects such as vehicles, a self-injury accident such as a collision of an object such as a vehicle with a structure, a personal accident where an object such as a vehicle collides with a person, etc. It is good to do.

(2) In the system of the above (1), the control means has a frequency lower than that when an image is recorded when an acceleration equal to or greater than the predetermined level is generated by a plurality of conditions being satisfied as the specific condition. It is preferable that an image can be recorded.

  In this way, for example, when a plurality of conditions are satisfied, an image can be recorded at a lower frequency than when an image is recorded when an acceleration of a predetermined level or more is generated. It becomes possible to reduce it reliably. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, for example, even if it is a condition that cannot always reduce the verification load for an abnormal situation alone, when a plurality of such conditions are satisfied, an image is recorded when acceleration occurs. In some cases, it may be possible to reduce the burden of verification of abnormal situations. Note that it is preferable that the timing at which each of the plurality of conditions is satisfied be achieved at a timing (within a predetermined time) which is close to a certain extent.

  Examples of “satisfying multiple conditions” include, for example, that other conditions are satisfied in addition to the occurrence of more than a predetermined acceleration, or a plurality of other conditions that are different from the occurrence of more than a predetermined acceleration. Can be mentioned.

  The individual conditions that constitute a plurality of conditions are, for example, that a specific acceleration has occurred (for example, an acceleration that has occurred when an impact of a specific magnitude has occurred), a vehicle equipped with a system, etc. The approach of a heavy object that can cause an accident to an object, the occurrence of an abnormal sound (a loud collision sound, human scream, etc.), an object such as a vehicle is identified within a specific time after a specific acceleration occurs. That the vehicle has stopped for more than a certain period of time, an object such as a vehicle has decelerated (for example, decelerated to a very low speed) within a specific time after a specific acceleration has occurred, and the user's physical state is different from that during normal driving. (The user's heart rate is higher than the predetermined value, the user's respiratory rate is higher than the predetermined value, and the user's head position is out of the predetermined area. System) Some parts of the camera's field of view of the system were covered with some object, contacted an accident support center that provided services to support the accident, and around the vehicle An object such as a specific vehicle (for example, an emergency vehicle such as an ambulance or a police car) is stopped, an object such as a vehicle equipped with the system is passing through a place where an accident is likely to occur, the system is installed It is preferable that an object such as a vehicle is driven in a time zone where the possibility of an accident is high.

  The user may be, for example, a driver of a vehicle or a person different from the driver, for example, a passenger.

  Here, the above-mentioned "a heavy object that can cause an accident to an object such as a vehicle or the like approaches" may be detected, for example, by image processing an image captured by an imaging device of the system. Moreover, it can also detect with various sensors, such as a microwave sensor. Detects that the distance between the vehicle position and the surrounding heavy objects has become a predetermined distance using an image of the vehicle viewed from above, such as an around view image generated based on images from multiple cameras. Good. The "approach" of the above-mentioned "the approach of a heavy object that may cause an accident to an object such as a vehicle" preferably means that the distance between the vehicle and the heavy object has become zero. It is preferable to determine whether the "heavy load that can cause an accident to an object such as a vehicle" is, in particular, whether the height of the object around the vehicle is a predetermined value or more. Whether or not the height of an object around the vehicle is a predetermined value or more may be detected based on an image of at least one of a microwave sensor or a camera. Further, the “predetermined” height of the object around the vehicle is preferably higher than the vehicle height. This is because an object lower than the vehicle height can pass under the vehicle.

  The “abnormal sound has occurred” is particularly good when, for example, a short and loud voice has been generated.

  “A short and loud voice has occurred” can be detected, for example, by analyzing the sound collected by a microphone mounted on an object such as a vehicle. The loud and short voices may be, for example, voices of surprises or screams such as “W”, “A”, “K”.

  In addition, the condition that “the vehicle has stopped within a specific time after the specific acceleration is detected” or “the vehicle has decelerated within the specific time after the specific acceleration is detected” is used. Is effective in reducing the burden of verification of abnormal situations. Immediately after the occurrence of an accident, attention is paid to the fact that the vehicle is often decelerated and stopped for confirmation of the current car or negotiation with the other party causing the accident, and this may be detected.

  The “vehicle is stopped for a specified time or more within a specified time” may be, for example, stopping within 3 to 5 minutes from the state of a specified average speed or more and continuing the stopped state for 5 minutes or more.

“The vehicle decelerates within a specific time” may be, for example, that the vehicle decelerates to a very low speed (eg, 8 km / h or less) within 3 to 5 minutes.
The vehicle speed may be calculated, for example, by acquiring a vehicle speed pulse, but may be acquired from GPS.

  In addition, it is effective in reducing the verification load for an abnormal situation to set one of the above conditions “the heart rate above the predetermined value of the user” and “the respiratory rate above the predetermined value of the user”. If an accident occurs, the user pays attention to the fact that the user is often upset and the heart rate and respiratory rate increase, and it is preferable to detect this.

  Further, it is effective to reduce the load of verification of the abnormal situation by setting the above-mentioned “the position of the user's head deviates from the predetermined area” as one of the conditions. In the case of a serious accident, the impact of the accident causes the body to shake greatly and lose consciousness, and the position of the head largely deviates from normal driving and the position of the head can not be recognized in many cases. It is a focus of attention, and it is good to detect this.

(3) In the system according to (1) or (2), the control means may be configured such that, as the specific condition, in addition to the generation of the acceleration greater than or equal to the predetermined condition, other conditions are satisfied, so It is preferable that an image can be recorded at a lower frequency than when an image is recorded when it occurs.

  In this way, for example, it is possible to reduce the verification load of an abnormal situation while utilizing a conventional sensor (acceleration sensor).

  As the "other conditions", for example, a heavy object that may cause an accident to approach the vehicle equipped with the system, an abnormal sound (a loud collision sound, a human scream, etc.), a specific acceleration, etc. What happens when a vehicle stops within a specific time after it occurs, when the vehicle decelerates within a specific time after a specific acceleration occurs (for example, decelerates to a very low speed), and when the user's physical condition is during normal driving Different states (such as a user's heart rate being above a specified value, the position of the user's head deviates from a specified area, etc.), the view of the camera of this system during operation of the system A service that supports accident response, in which a portion of the vehicle's predetermined percentage or more is covered with any object (for example, a deployed airbag, an object in the vehicle that has been moved from a position before the accident due to an accident impact, etc.) There is a possibility that an accident support center has been contacted, a specific vehicle (for example, an emergency car such as an ambulance or police car) stops around the vehicle, or an object such as a vehicle equipped with the system may cause an accident. It is preferable that the vehicle passes through a high place, or that an object such as a vehicle equipped with the system is being driven in a time zone where the possibility of an accident is high.

(4) In the system according to any one of (1) to (3), the control means may obtain specific information from the user as the specific condition, and obtain specific information from the user. It is preferable that an image can be recorded at a lower frequency than when an image is recorded when acceleration above a predetermined level occurs due to the establishment of another different condition.

  In this way, for example, it is possible to more reliably reduce the verification load of the abnormal situation, etc. by the information obtained from the user.

  The “specific information” may be, for example, a specific action of the user, a specific change in the user's body, or the like.

(5) In the system according to any one of (1) to (4), the control unit has a function of prompting a user to perform a specific action, and the control unit has the specific condition as the specific condition. It is preferable to have a function of recording an image in the predetermined recording area when an action is performed and when another condition different from that of the specific action is satisfied.

  According to this, for example, when a specific action is prompted to the user and the user executes the specific action, an image is recorded. Therefore, useless image recording can be further suppressed, and the verification load for abnormal situations can be more reliably reduced.

  As the “specific action”, for example, an operation of an operation member that receives an operation by the user can be mentioned.

  As the “function for prompting a specific action”, for example, when one of a plurality of conditions is satisfied in the system of any one of the above (2) to (4), the operation member is notified to the user For example, visual or auditory prompting may be mentioned. As the function to prompt visually, for example, a word to light the operation member (for example, to make it blink, etc.) or to prompt the operation of the operation member to the display device provided on the vehicle (for example, "press the operation button") , “Do you want to press the operation button?”). For example, as a function prompting aurally, the operation of the operation member is performed by a voice (for example, a voice such as "Please press the operation button", "Do you press the operation button?") Through the speaker provided on the vehicle Can be encouraging. At that time, for example, “Please press the operation button of ○ color (for example, red, yellow, etc.)” and “Press the button surrounded by circle of ○ color (for example, red, yellow, etc.)” It is better to prompt the operation of the member.

(6) In the system according to any one of the above (1) to (5), the control means has a function of detecting a specific change in the user's body, and the control means is characterized by: An image is displayed in the predetermined recording area when a specific change in the user's body is detected and another condition different from the detection of the specific change in the user's body is satisfied. It may have a recording function.

  In this way, for example, unnecessary recording of images can be further suppressed, and the load of verification of abnormal situations can be more reliably reduced. When an abnormal situation such as an accident occurs, attention is paid to the fact that a specific change of the user's body is likely to occur, and this may be detected.

(7) In the system according to any one of the above (1) to (6), the control means has a communication function capable of communicating with user's belongings owned by the user, and the control means is provided with the specific condition. As an opportunity that the user property communicates with a specific device and that another condition different from that the user property communicates with the specific device is satisfied, an image is displayed in the predetermined recording area. It is desirable to have a function of recording.

  In this way, for example, when a user calls a specific device (for example, a telephone of an insurance company) from a user property such as a portable terminal (for example, a smartphone), an image (for example, an image of an abnormal situation) is automatically generated. ) Can be recorded. In addition, useless image recording can be further suppressed, and the verification load for an abnormal situation can be reduced more reliably.

  As the “user property”, for example, a smartphone, a mobile phone, a tablet terminal, etc. owned by the user can be mentioned. The system and the user property can be made communicable with each other by pairing or the like in advance by Bluetooth (registered trademark), for example. For example, it is preferable to register in advance the phone number of the contact point such as an insurance company or a police station (a phone number to be contacted when an abnormal situation such as an accident occurs) in the user's possession. The system may record the transmission history of the user property at any time.

(8) In the system according to any one of (1) to (7), the control unit is configured to execute the predetermined condition when a single condition different from the generation of the acceleration of the predetermined value or more is satisfied as the specific condition. It is preferable that an image can be recorded at a lower frequency than when an image is recorded when the above acceleration occurs.

  According to this, by recording an image triggered by the establishment of a single condition, it is possible to reduce the load of verification of an abnormal situation while suppressing the number of parts of the system, for example.

  “Single condition” refers to, for example, the operation of a safety device (for example, an airbag, an anti-lock / brake system, a seat belt pretensioner device, etc.) provided in the vehicle, or a device for protecting the body provided in the vehicle (for example, Airbags, seat belt pretensioner devices, etc.), vehicle changes during a vehicle collision (eg, changes in vehicle potential, vehicle deformation, etc.), specific changes in the user's body (eg, abnormalities in the user's body) , A specific change of the user's posture), that a predetermined sensor attached to the drive handle is detached from the drive handle, and the like. As an abnormality of the user's body, for example, it is preferable to stop the heartbeat.

  The state of the airbag can be detected, for example, by monitoring communication contents of a CAN (Controller Area Network) mounted on the vehicle. Note that it is possible to detect, for example, airbag deployment, back collision, airbag system abnormality, safing, front collision, side collision, etc., based on the communication content of CAN. Further, the state of the air bag may be detected by accessing the air bag ECU. Moreover, the state of the airbag is monitored by monitoring the operation sound of the airbag (for example, monitoring of a loud explosion sound of 150 db to 170 db in 100 ms or less), monitoring the change in air pressure accompanying the operation of the airbag, or being mounted on a vehicle. It is good to detect by OBD (fault diagnosis device) etc.

  The above-mentioned "potential change of the vehicle" is, for example, focused on the fact that the metal body is always charged because it is on the tire which is an insulator, and the potential of the body changes when it contacts with an obstacle. It is good to detect this.

  "The user's heart rate can not be measured" focuses on the fact that if an accident occurs it may become impossible to measure the heart rate (in the case of death, etc.) good.

(9) In the system according to any one of the above (1) to (8), the control means may have a function of recording an image in the predetermined recording area triggered by the operation of a safety means.

  In this way, for example, unnecessary image recording can be further suppressed, and the load of verification of abnormal situations can be further reduced.

  “Safety measures” include, for example, safety devices such as airbags, ABS (anti-lock / brake systems), seat belt pretensioner devices, and software and functionally ensuring vehicle and body safety. May be. In particular, actuation of the safety means may be performed without attaching any of the means for detecting actuation (e.g. of the air bag) to the safety means itself. For example, when connecting to a signal line that outputs a signal indicating the operation of the safety means, or by recognizing an image captured by the imaging means for capturing an image and detecting the operation of the safety means, Good.

(10) In the system according to any one of (1) to (9), the control unit has a function of recording an image in the predetermined recording area triggered by an operation of a unit that protects a user's body. Good.

  In this way, for example, unnecessary image recording can be further suppressed, and the load of verification of abnormal situations can be further reduced. When an abnormal situation occurs, attention is paid to the fact that there is a high possibility that the means for protecting the body provided to the object such as a vehicle operates, and it is preferable to detect this.

  As the "means for protecting the body", for example, an air bag, a seat belt pretensioner device, or software may be used to functionally ensure the safety of the vehicle or the body.

(11) In any one of the systems (1) to (10), the control unit has a function of recording an image in the predetermined recording area triggered by a change in potential of a vehicle on which the system is mounted. It is good to have.

  In this way, for example, unnecessary image recording can be further suppressed, and the load of verification of abnormal situations can be further reduced. This is because when an abnormal situation occurs, there is a high possibility that a potential change of the vehicle (for example, a metal part of the vehicle body) will occur.

(12) In the system according to any one of (1) to (11), the control means may have a function of recording an image in the predetermined recording area in response to the generation of a specific sound.

  In this way, for example, unnecessary image recording can be further suppressed, and the load of verification of abnormal situations can be further reduced. This is because when an abnormal situation occurs, there is a high possibility that a specific sound will occur.

  As the “specific sound”, for example, a collision sound of a vehicle, a scream of a person, a siren sound of an emergency car, a sound of a sudden brake, and the like can be mentioned.

(13) The system according to any one of (1) to (12), further including an operation member that receives an operation by a user, wherein the control unit is triggered by an operation of the operation member by the user as the specific condition. It is preferable to have a function of recording an image in a predetermined recording area.

  In this way, for example, it is possible to further reduce the abnormal state verification load with a relatively simple configuration. This is because the intention of the user is reflected by recording an image triggered by the operation of the operation member by the user.

  As the "operation member", for example, a push button, a switch, an operation lever and the like can be mentioned.

(14) The system according to any one of the above (1) to (13), further including an operation member having a specific size as an operation member capable of receiving an operation by the user, the control means It is preferable to have a function of recording an image in the predetermined recording area in response to an operation.

  If it does in this way, operation of an operation member will become easy. For example, it becomes possible to easily operate even when the abnormal situation occurs, even when it is uneasy.

  The specific size of the “operation member” may be, for example, a size that can be accurately operated when the hand is extended quickly.

(15) In the system according to any one of (1) to (14), an operation member provided at a specific position is provided as an operation member capable of receiving an operation by a user, and the control unit includes: It is preferable to have a function of recording an image in the predetermined recording area in response to an operation.

  If it does in this way, operation of an operation member will become easy. For example, it becomes possible to easily operate even when the abnormal situation occurs, even when it is uneasy.

  The specific position of the “operation member” can be, for example, a position where the operation can be accurately performed when the hand is extended quickly.

(16) In the system according to any one of the above (1) to (15), a single operation member is provided as an operation member capable of receiving an operation by the user, and the control means is of the single operation member. It is preferable to have a function of recording an image in the predetermined recording area in response to an operation.

  If it does in this way, operation of an operation member will become easy. For example, it becomes possible to easily operate even when the abnormal situation occurs, even when it is uneasy. When a plurality of operable members are provided, there is a possibility that the user may wonder which operating member should be operated when the user is quick, but the operating member is an operating member operable by the user. By being provided as a single operation member, the operation member can be operated without being lost.

(17) The system according to any one of the above (1) to (16) may include, as an operation member capable of receiving an operation by the user, an operation member capable of determining an erroneous operation by the control means.

  In this way, for example, when the operation member is misoperated, it is possible to cancel the operation. In this case, for example, when it is determined that the operation is an erroneous operation, the control unit may automatically cancel the operation, or the control unit may confirm to the user whether the operation was an erroneous operation.

  Examples of the “erroneous operation” include an erroneous operation and a mischievous operation.

(18) In the system according to any one of (1) to (17), the control means causes an image to be recorded in the predetermined recording area in response to reception of specific information from the outside as the specific condition. It may have a recording function.

  According to this, for example, it is possible to further reduce the verification load as to whether or not the image recorded in response to specific information received from the outside is an image of an abnormal situation such as an accident. Moreover, accidents of other vehicles can be recorded and used for verification of accidents of the other vehicles.

  Examples of the "specific information" may include information on an abnormal state (for example, an accident) of an object such as another vehicle, an emergency vehicle such as a police car or an ambulance stopped nearby, and the like. As information on the abnormal situation of an object such as another vehicle, there can be mentioned, for example, information such as an occurrence place and an occurrence time of an accident of an object such as another vehicle. The information on the accident of an object such as another vehicle is, for example, transmitted from a server (for example, a server of an insurance company or a police station) outside the object such as a vehicle. In addition, when an emergency vehicle such as a police car or an ambulance stops nearby, for example, the sound of a siren such as a police car is collected and analyzed by a microphone provided on an object such as a vehicle equipped with this system. It is better to recognize it.

  In addition, as the “specific information”, for example, inquiry information from an external device (for example, a server) for another vehicle different from the vehicle on which the present system is mounted can be mentioned. As the “inquiry information”, for example, information on an accident (for example, position information, time information, etc.) of the other vehicle from the insurance company or the police station can be mentioned. In this case, for example, the control means searches the video of the accident corresponding to the information of the inquired accident out of the images already always recorded in the predetermined recording area, and the video of the accident found by the search You may record (event recording). The recorded information may be transmitted to an external device.

(19) The system according to any one of the above (1) to (18) may include transmission means for transmitting an image recorded in the predetermined recording area to the outside.

  In this way, by transmitting the image to the outside, the trouble of carrying the memory card can be reduced.

(20) In the system according to any one of the above (1) to (19), the control means has a function of ranking the images recorded in the predetermined recording area based on the possibility of the occurrence of an abnormal situation. Good.

  In this way, by ranking the images based on the possibility that an abnormal situation appears, it is possible to further suppress the recording of useless images and to further reduce the verification load of the abnormal situation.

  For example, when the rank of the image regarding the possibility that an abnormal situation appears is higher than a predetermined rank, the image may be transmitted to a server or the like of the insurance company. Such a rank that can further reduce the abnormal condition verification load may be embedded together with the corresponding image or in the corresponding image and recorded.

(21) In the system according to any one of the above (1) to (20), the control means may have a function of writing information of a vehicle in which an abnormal situation may occur in an image.

  In this way, it is possible to easily check the image of the abnormal situation and easily identify the vehicle in which the abnormal situation has occurred.

  Examples of the “vehicle that may have an abnormal situation” include a vehicle equipped with the present system and another vehicle different from a vehicle equipped with the present system.

  Examples of the "information on a vehicle that may have an abnormal situation" include a vehicle number, a vehicle verification number, the name of the owner of the vehicle, and the like.

  The “information on the vehicle that may have an abnormal situation” may be described in an image, for example, as a telop.

(22) In the system according to any one of the above (1) to (21), the control means may have a function of writing probability information indicating the probability that an abnormal situation appears in the image in the image.

  In this way, it is possible to easily determine whether or not the image is an abnormal situation with reference to the probability information indicating the probability that the abnormal situation appears in the image, thereby further increasing the verification load of the abnormal situation. Can be reduced.

  The “probability information indicating the probability that an abnormal situation appears” may be described in an image, for example, as a telop.

(23) In the system according to any one of the above (1) to (22), the control means may have a function of recording the image in a still image state.

  In this way, it is possible to further reduce the verification load for abnormal situations. For example, if it is a moving image, it may take a relatively long time to confirm even if it is fast-forwarded. However, if it is a still image, a plurality of still images can be confirmed at the same time. Confirmation work can be performed.

(24) In the system according to any one of the above (1) to (23), the control means may have a function of switching the performance of the system at a plurality of levels.

  In this way, for example, it is possible to switch the system performance between the personal mode in which the performance setting for personal use is possible and the business mode in which the performance setting for business use is possible. Therefore, the system performance can be arbitrarily set according to who the system user is. For example, the performance for individuals may be set to an average (medium) performance. Further, as performance for corporations, the image quality of the video may be set to a high image quality, or image transmission to the outside may be performed by LTE (Long Term Evolution) (registered trademark).

(25) In the system according to any one of the above (1) to (24), the control means may have a function of setting levels by industry.

  In this way, for example, when the user is a security company, for example, the image quality of the video or the like is set to the highest image quality (highest setting) or the image transmission to the outside is LTE (Long Term Evolution) (registered trademark) ).

(26) The program may be characterized in that the function of any one of the systems (1) to (25) is realized by a computer.

  In this way, the above system can be realized by mounting a computer storing the program in the system.

  The above-described inventions shown in (1) to (26) can be arbitrarily combined. For example, at least a part of the configuration of at least one invention of (2) or later may be added to the configuration of all or part of the invention shown in (1). In particular, the invention shown in (1) may be an invention in which at least a part of at least one of the inventions after (2) is added.

[System configuration]
An example of a system configuration will be described with reference to FIGS. 1 and 2. The "system" may be a system mounted on an object other than a vehicle. In an example of an object other than a vehicle, for example, a system mounted on a ship or an airplane may be used. However, a system mounted on a vehicle is particularly preferable. The “system” may be a so-called drive recorder that records images such as the moment of a traffic accident. Examples of vehicles include not only general vehicles such as transportation vehicles (for example, trucks and forklifts), business vehicles (for example, taxis and buses), and general vehicles, but also more versatile vehicles. Also good. In the present embodiment, a drive recorder that can be mounted on a vehicle will be described.

  FIG. 1A is an example of a perspective view of a system (drive recorder) as viewed obliquely from the rear. As shown in FIG. 1A, an SD card insertion slot 114 is provided on one side of a housing of the system 100. A display 113 and a plurality of operation members (a plurality of operation buttons 112 and 115 in the example shown in FIG. 1A) are provided on the back of the housing. A joint rail 111 is provided on the top surface of the housing. Although not shown in FIG. 1A, a lens of a camera which is an imaging unit is provided on the front surface of the housing. A DC jack is provided on the side surface that does not appear in FIG. 1A, and a speaker and an HD output terminal are provided on the bottom surface.

  A camera (imaging means) including a lens captures an image in front of the vehicle, for example. The DC jack is a jack for connecting to a DC power source via a power cable. An SD card insertion slot 114 is an insertion slot for inserting an SD card. The speaker outputs sound such as voice. The HD output terminal is a terminal for connecting to another information device via a cable. The joint rail 111 is for attaching a joint member for mounting the system 100 on a vehicle. The display 113 displays various images. The operation buttons 112 and 115 are for inputting various commands to the system 100 when operated by the user.

  In this specification, the user may be, for example, a driver such as a vehicle equipped with the system, or may be a person different from the driver, for example, a passenger.

  FIG. 1B is a diagram illustrating an example of the system 100, the windshield 122, the dashboard 126, and the like mounted on the vehicle. In the example shown in FIG. 1A, the system 100 is disposed at a position on the front passenger's seat side adjacent to the rear view mirror 121, which is an upper portion of the windshield 122 of the vehicle and near the center in the left-right direction. The system 100 is fixed to the windshield 122 by an attachment member such as a double-sided tape. The DC jack of the system 100 is connected to the cigar socket 123 via the power cable 120. When an accessory power source such as a vehicle is turned on, power is supplied from the cigar socket 123 to the system 100, for example. Therefore, when the engine of the vehicle or the like is off, no power is supplied to the system 100 from the cigar socket 123.

  Note that, as shown in FIG. 1A, some members of the system 100 may be provided at different positions from the windshield 122, depending on the application of the members. In the example shown in FIG. 1A, for example, an operation button 124 or the like which is one of the operation members is provided on the dashboard 126.

  FIG. 2 is an example block diagram of the system 100. The system 100 includes a controller 130 (an example of a control unit), a camera 141 (an example of an imaging device), a database 145, a GPS receiver 140, an SD card reader 142 (an example of a recording unit), and an acceleration sensor 144. , Various types of sensors 150 different from the acceleration sensor 144, a speaker 146, a display 113, operation buttons 112, 115 and 124 (see FIG. 1B), and a communication circuit 149. The SD card reader 142 has a read / write function, and should be referred to as an “SD card reader / writer” in the strict sense of the present invention, but in the present specification, it is simply referred to as an “SD card reader”.

  The speaker 146 and the display 113 function as notification means for notifying the user of various information. The speaker 146 outputs an alarm and various information with sound based on the control of the controller 130. The display 113 outputs various information as an image display based on the control of the controller 130. The operation buttons 112, 115, and 124 function as input means for the user to give various commands to the system 100 (more specifically, the controller 130).

  The camera 141 functions as an imaging device that captures a moving image within the angle of view (within the field of view). A moving image captured by the camera 141 is captured by the controller 130 as image data. The camera 141 can capture at least the front of the vehicle. The camera 141 may be a 360 ° camera capable of imaging 360 ° in all directions, and may be either an omnidirectional camera or a hemispherical camera. If it is a 360 degree camera, while being able to image all the circumference | surroundings of a vehicle, the state in a vehicle can also be imaged. The number of cameras 141 may be one, or two or more. The camera 141 may be able to capture images of users (drivers and passengers) in the vehicle in addition to the situation around the vehicle.

  The database 145 is stored, for example, in a non-volatile memory (for example, an EEPROM) externally attached to the controller 130. The database 145 includes, for example, map data.

  The GPS receiver 140 detects the position information of the vehicle at the current time based on the instruction of the controller 130. The position information includes the time obtained based on the signals from the GPS satellites, the speed of the vehicle, longitude, latitude, altitude and the like. The controller 130 performs a process of recording the history of the position information.

  The SD card reader 142 functions as a medium storage unit that holds the SD card 143. The SD card 143 functions as a removable storage medium. The user can attach the SD card 143 to the SD card reader 142 through the SD card insertion slot 114 (see FIG. 1A). The SD card reader 142 reads data from the SD card 143 held in the SD card reader 142 or stores data in the SD card 143 based on control from the controller 130.

  The acceleration sensor 144 is a three-axis type sensor that detects acceleration and inclination in the directions of the three axes (x-axis, y-axis, and z-axis). The measured value by the acceleration sensor 144 is always taken into the controller 130. The controller 130 acquires acceleration information of three axes every 10 ms, for example.

  The controller 130 has known CPUs 131, memories such as a ROM 132 and a RAM 133, a timer 134, and other peripheral circuits. Various programs are stored in the ROM 132 of the controller 130. The controller 130 implements various functions by executing these programs. The various programs include an operating system (OS), a GPS information processing program, a video processing program (for example, flowcharts shown in FIGS. 3 to 14), a communication processing program, and the like.

  The controller 130 can store the GPS information received by the GPS receiver 140 in the SD card 143 held by the SD card reader 142 by executing the GPS information processing program. By executing the video processing program, the controller 130 can record the video captured by the camera 141 in a predetermined recording area of the SD card 143 in association with the time. The controller 130 has a function of accessing the SD card 143 held by the SD card reader 142, and a control means having a function of recording an image captured by the camera 141 on the SD card 143 held by the SD card reader 142. Function as.

  The display 113 functions as a notification unit that notifies the user of the role of the SD card 143 accessed by the controller 130.

  The communication circuit 149 functions as a communication means for performing wireless communication with an external device such as a server (for example, a server such as an insurance company), a personal computer, a smartphone, a tablet terminal or the like. The controller 130 has a function of transmitting image data such as video to an external device through the communication circuit 149 by executing a communication processing program. As the communication circuit 149, for example, it is preferable to use a communication circuit conforming to the standard of short distance wireless communication such as WiFi standard or Bluetooth, or the standard of a mobile communication system such as LTE (Long Term Evolution) (all registered trademark) or 4G. . The standard for short-range wireless communication can be applied to communication between a work vehicle (forklift or the like) operating on the premises and an external device, for example. The standard of the mobile communication system can be applied to, for example, communication between a vehicle moving within a wider area and an external device.

  The controller 130 executes the above-described video processing program by recording an image on the SD card 143 held by the SD card reader 142 based on the image data input from the camera 141. More specifically, the SD card 143 is divided into at least two recording areas (a first recording area and a second recording area), and the first recording area is constantly recorded as long as power is supplied from the vehicle. The compressed image data (hereinafter referred to as "always recorded image data") is compressed and recorded. Further, in the second recording area, image data (hereinafter referred to as “event recording image data”) which is recorded when a specific condition is met when power is supplied from a vehicle is recorded. Although details will be described later, the controller 130 performs a multitasking process of recording the constantly recorded image data (always recording process described later) and the process of recording the event recorded image data (event recording process described later). Run.

  As described above, the system 100 is not supplied with power from, for example, the cigar socket 123 when an accessory power source (hereinafter referred to as “external power source”) such as a vehicle is turned on. Therefore, the system 100 may be a system with an anti-theft system that includes a built-in battery having a function of charging when the external power is on and supplying power only to the controller 130 and the acceleration sensor 144 when the external power is off. In this case, when a strong impact is detected by the acceleration sensor 144 in the theft recording mode, the controller 130 also detects other members (for example, the camera 141, the SD card reader 142, the display 113, etc.) other than the controller 130 and the acceleration sensor 144. Power is supplied from the built-in battery, and imaging is performed for a time necessary for imaging fraud such as theft such as about 1 minute, and processing for recording this imaging data is executed. Then, when the external power supply is turned on, the antitheft mode is ended, and the processes shown in FIGS. 3 to 14 described later are executed.

  For example, the images of the constantly recorded image data and the event recorded image data may be images in which still images are continuous, or may be moving images. In the case of a still image, since it is possible to check a plurality of still images simultaneously, it is possible to efficiently perform a check operation. Also, the moving image may be, for example, a moving image obtained by continuously displaying a series of images captured at fixed time intervals at short intervals, or even a completely continuous image. Good.

  In addition, vehicle data (for example, vehicle verification number, chassis number, owner's name, etc.) may be attached to still images and moving images. Further, it is preferable that the operation button 124 be a single button and that no button other than the operation button 124 be provided. Since the single operation button 124 is provided as an operation button that can be operated by the user, the operation button 124 can be operated without hesitation in an emergency such as a traffic accident.

  Next, control processing of the controller 130 included in the system will be described. The control process executed by the controller 130 will be described separately in the first embodiment, the second embodiment and the third embodiment. The configuration of the system shown in FIG. 1 and FIG. 2 is common to the first embodiment, the second embodiment, and the third embodiment. Therefore, the control processing executed by the controller 130 will be described below. Only explained.

  In the first embodiment, for example, an event recording process for recording event recording image data when there is a possibility that an abnormal situation such as an accident has occurred in the own vehicle (a vehicle equipped with the system) or the like has a plurality of conditions. This is an example in which the event recording process is performed, and the event recording process may be performed less frequently than the case in which the event recording process is performed when a single condition such as the occurrence of an acceleration exceeding a predetermined value is satisfied. is there.

  In this specification (including not only the first embodiment but also second and third embodiments described later), “occurrence of acceleration exceeding a predetermined value” means, for example, a vehicle or the like The time when the vehicle exceeds the range of acceleration that occurs when traveling. For example, when a vehicle or the like is traveling normally, the acceleration often fluctuates within a normal range although there is a slight vertical width. However, for example, when a vehicle or the like rides on a step, or at the time of a sudden braking, the acceleration may rise temporarily (for example, momentarily). In such a case, it can be determined that an acceleration of a predetermined value or more has occurred.

  In the second embodiment, an event recording process for recording event recording image data when there is a possibility that an abnormal situation such as an accident has occurred in the own vehicle (a vehicle equipped with the system) or the like is greater than or equal to a predetermined value. This is an example of the case where a single condition different from the occurrence of acceleration is satisfied, which is an event recording compared to the case where an event recording process is performed when a single condition such as the occurrence of acceleration higher than a predetermined value is satisfied. This is an example in which the frequency of processing may be low.

  In the third embodiment, for example, an event recording process for recording event record image data when there is a possibility that an abnormal situation such as an accident has occurred in another vehicle (a vehicle different from the vehicle equipped with the system) or the like. It is an example of the case of performing.

[First embodiment]
First, with reference to FIG. 3, a first embodiment of control processing executed by the controller 130 will be described. FIG. 3 is a flowchart for explaining a first embodiment of control processing executed by the controller 130 of the system 100.

  The controller 130 determines whether or not the external power supply is ON (step S101). When the external power supply is ON (YES in step S101), the controller 130 performs the processes of steps S103 to S109. Although not shown in FIG. 3, when power is supplied to the system 100 and the external power supply is turned on, the controller 130 converts the image data (always recorded image data) input from the camera 141 to the first card of the SD card 143. A constant recording process to always record in the recording area is performed. This continuous recording process is a process that continues recording as long as power is supplied to the system 100, and is performed in parallel with the processes of step S103 to step S109, for example.

  In step S101, when the supply of power to the system 100 is started and the external power supply is turned on (in the case of YES), the controller 130 generates an acceleration of a predetermined value or more in the vehicle based on the detection value of the acceleration sensor 144. It is determined whether or not it has been made (step S103).

  Specifically, the controller 130 monitors whether or not the user has performed a specific action until a predetermined time has elapsed (step S105) after an acceleration of a predetermined value or more occurs (YES in step S103). (Step S107). The monitoring of whether or not the user has performed a specific action may be, for example, monitoring whether or not the user has operated the operation button 124. If the user knows that the system records image data when the operation button 124 is operated, the reliability of the occurrence of an event when the user operates the operation button 124 is increased.

  If controller 130 determines that the user has operated, for example, operation button 124 as a specific action within a predetermined time (YES in step S105) after an acceleration equal to or higher than a predetermined value is generated (YES in step S107), An event recording process is performed (step S109). In this event recording process, for example, the constantly recorded image data recorded in the first recording area of the SD card 143 is read, and it is determined that an acceleration equal to or greater than a predetermined value is generated for a predetermined time (for example Processing for cutting out the image data of each second) and recording it as event recording image data in the second recording area of the SD card 143 or the like. In this case, the predetermined time (monitoring time as to whether the user has operated the operation button 124) determined in step S105 is, for example, within 20 minutes after the detection of the occurrence of the acceleration higher than the predetermined value. It is preferable that a certain amount of time can be secured until the user operates the operation button 124. This is because when an abnormal state such as an accident occurs, the user is considered to be upset, and it is considered that the user may not be aware of operating the operation button 124 unless he / she is mentally depressed.

  Further, when the acceleration equal to or more than the predetermined value is not generated (NO in step S103), the controller 130 returns to step S101. In addition, even if acceleration equal to or greater than a predetermined value occurs, the controller 130 does not detect that the user has performed a specific action and when a predetermined time elapses after the occurrence of acceleration equal to or greater than the predetermined value (NO in step S105). ), Return to step S101.

  In this way, when a plurality of conditions such as detection of the occurrence of acceleration of a predetermined value or more and detection of the user performing a specific action are satisfied, an acceleration of a predetermined value or more is generated. Since the image can be recorded at a lower frequency than when the image is recorded, it is possible to more reliably reduce the verification load of the abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, since the timing at which individual conditions among the plurality of conditions are established is close to a certain degree (within the predetermined time described in step S105 above), high relevance of the plurality of conditions is ensured. Is done. Therefore, it is possible to more reliably reduce the verification load for abnormal situations.

  If the process of step S107 is, for example, a process of detecting that the user has operated the operation button 124, it is preferable that the system be provided with a function to prompt the operation of the operation button 124. For example, when the occurrence of an acceleration above a predetermined value is detected, an audio announcement such as "Please press the operation button in an emergency" is output from the speaker, or the effect is displayed on the display device, or the operation is performed. The button 24 may be turned on or blinked, or a combination thereof. Moreover, it is preferable that the operation button 24 is provided in the system in a conspicuous manner. For example, the operation button 24 may be arranged on the dashboard, or the operation button 24 may be arranged at a position that is easy to see from a person sitting in the driver's seat or the passenger seat. The operation button 24 may be an operation button of a conspicuous color (for example, red, yellow, blue, etc.). Further, the operation button 24 may be a large size so as to stand out (an emergency button image, for example, the size of the back of a hand). Furthermore, if the number of operation buttons is large, the user may wonder which operation button should be operated when the user operates, so it is preferable to provide only one operation button 24.

  The operation button 24 is not only when an abnormal situation such as an accident occurs in the own vehicle or another vehicle, or when something happens to the driver's body or a passenger's body, a fire, a flood, a meteor fall, etc. When a situation occurs, when operating, the system sends external specific agencies (eg, police station, fire department, Japan Automobile Federation, insurance company, accident support center, etc.) or external specific vehicles (eg, ambulance, police car, etc.) Communication is preferably performed to have the function of notifying the other party of the occurrence of an abnormal state through this communication.

  In addition, the process of step S107 is not limited to the process of detecting that the user has operated the operation button 124. For example, a specific device (for example, a smartphone or a tablet) owned by the user may be used. It is also possible to detect that communication has been made with a police station, fire department, Japan Automobile Federation, insurance company, accident support center, etc.). In this case, the predetermined time determined in step S105 (monitoring time as to whether or not communication has been made from a specific device owned by the user to a specific external engine) detects that acceleration of a predetermined value or more has occurred. It is preferable that a certain amount of time until the user operates the operation button 124 can be secured, for example, within 60 minutes after that. Considering that the user may negotiate with the other party of the accident when an abnormal condition such as an accident occurs, it is considered that after the negotiation with the other party settles down, there is a possibility of communicating with a specific external organization. It is.

  Further, the system may prompt the user to perform communication with the specific engine, or may confirm with the user whether or not to perform communication with the specific engine. For example, the system may confirm with the user by an interactive UI (user interface) whether to communicate (contact) to an accident support center that performs a service that supports an accident response.

  Specifically, for example, after an acceleration of a predetermined value or more occurs (YES in step S103), the system notifies the user “notify the accident support center” until a predetermined time has elapsed (step S105). Do you want to check it by voice? In this case, the system may recognize by voice a response such as “Yes / No” by the user, and the system may contact the accident support center when the “Yes” response is received. When making this contact, as a precaution, the system may record a voice conversation with the user, make the above contact, and send the recorded content as a voice message to the accident support center.

  In addition, for example, after an acceleration of a predetermined value or more occurs (YES in step S103), the system informs the user “Do you want to notify the accident support center?” Until a predetermined time has elapsed (step S105). In the case of notification, please press the notification button on the main unit. In this case, the system may contact the accident support center when the user operates the notification button.

  It is recommended to have a function to adjust the voice volume of the system by interactive UI, and a function to turn on / off the sound. By providing these functions, it is possible to suppress the sound from flowing each time an acceleration of a predetermined value or more occurs (YES in step S103) or to suppress the sound volume.

  It is detected that the process of step S107 is communicated from a specific device (for example, a smartphone or a tablet) owned by the user to an external specific organization (for example, a police station, a fire department, the Japan Automobile Federation, an insurance company, etc.) In the case of processing, it is preferable to register the telephone number of a specific institution in the system. The system and a specific device owned by the user may be in a state where they can communicate with each other by, for example, pairing in advance with Bluetooth (registered trademark). In addition, it is more preferable to record a history (for example, date and time and contents of conversation at the time of communication) when communication is performed from a specific device owned by the user to a specific external organization. In addition, the transmission history of a specific device owned by the user is read at any time, and event recording processing is performed for an acceleration occurrence event (YES in step S103) with respect to the time when the specific organization (insurance company etc.) is contacted. (Step S109).

[Effects and the like of the first embodiment]
According to the first embodiment, when a plurality of conditions (detection of occurrence of an acceleration greater than or equal to a predetermined value and detection that a user's specific action has been performed) are satisfied, acceleration greater than or equal to the predetermined value has occurred. Images may be recorded less frequently than when images are recorded. Therefore, by providing the image data recorded on the SD card 143 in the event recording process (step S109) to a specific external organization (for example, police station, fire station, Japan Automobile Federation, insurance company, etc.) It is possible to more reliably reduce the verification load of

[Modifications 1 to 5 of the first embodiment]
Next, modifications 1 to 5 of the first embodiment will be described with reference to FIGS. 4 to 8. The first to fifth modifications of the first embodiment are different from the first embodiment in some processes executed by the controller 130 of the system 100 shown in FIG.

[Modification 1 of the first embodiment]
First, with reference to FIG. 4, the modification 1 of a 1st Example is demonstrated. FIG. 4 is a flowchart for explaining a first modification of the first embodiment of the control process executed by the controller 130 of the system 100.

  In the first modification of the first embodiment, after an acceleration of a predetermined value or more occurs instead of or in addition to the determination of S107 in the first embodiment (determination of whether or not the user has performed a specific action) It is determined whether or not specific information has been detected from the user within the predetermined time period (YES in step S115) (step S117). That is, the user detected specific information from the user (YES in step S113) and within a predetermined time (YES in step S115) after occurrence of the acceleration in excess of the predetermined value (YES in step S113). If a plurality of conditions such as YES are satisfied, event recording processing is performed (step S119). Note that the other processes of steps S111, S113, and S119 are the same as the processes of steps S101, S103, and S109 in the first embodiment, respectively.

  Specifically, the controller 130 monitors whether or not specific information is detected from the user until a predetermined time has elapsed (step S115) after an acceleration equal to or greater than a predetermined value is generated (YES in step S113). (Step S117). The monitoring of whether or not the user has detected specific information may be, for example, monitoring of whether or not the user has made a loud voice (for example, a voice having a predetermined decibel value or more). This focuses on the fact that the user is likely to make a loud voice when an abnormal condition such as an accident occurs, and usually exceeds a range of digebel values where the possibility of being detected is low (for example, normal When a decibel value of, for example, twice or more of the maximum decibel value that may be detected at the time is detected), it is determined that the user has made a loud voice. In this case, the predetermined time (monitoring time as to whether or not the user made a loud voice) determined in step S115 is relatively short, for example, within 3 seconds after detection of the occurrence of acceleration equal to or greater than a predetermined value. Time is good. This is because when an abnormal condition such as an accident occurs, it is considered that the user makes a loud voice within a relatively short time.

  If controller 130 determines that the user made a loud voice, for example, as specific information from the user (YES in step S117) within a predetermined time (YES in step S115) after the acceleration equal to or greater than the predetermined value is generated (YES in step S117) An event recording process is performed (step S119).

  Further, when the acceleration equal to or more than the predetermined value is not generated (NO in step S113), the controller 130 returns to step S111. Further, even if acceleration of a predetermined value or more occurs, the controller 130 does not detect specific information from the user, and if a predetermined time elapses from the generation of the acceleration of the predetermined value or more (NO in step S115), step 130 Return to S111.

  In this way, when a plurality of conditions such as detection of the occurrence of an acceleration exceeding a predetermined value and detection of specific information from the user are satisfied, an image is recorded when an acceleration exceeding the predetermined value occurs. Since the image can be recorded at a lower frequency than in the case where it is used, it is possible to more reliably reduce the verification load of the abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, since the timing at which each of the plurality of conditions is satisfied is performed at a timing close to a certain extent (within the predetermined time described in step S115 described above), the level of relevance of the plurality of conditions is secured Is done. Therefore, it is possible to more reliably reduce the verification load for abnormal situations.

  Note that the process of step S117 is not limited to the process of monitoring whether the user has made a loud voice (for example, a voice having a predetermined decibel value or more). For example, monitoring of whether or not the user's body has changed You may do it. Whether or not the user's body has changed is monitored by detecting a user's heart rate by providing a sensor capable of measuring the user's blood flow, for example, on a steering wheel of a vehicle or the like in which the system is mounted. For example, when it is detected that the range of the heart rate which is usually detected at the normal time, such as outside the predetermined range (for example, the heart rate is 100 or more), is detected, it may be determined as a change in the user's body. Good. In this case, it is preferable to detect the heart rate of the user from the normal time, and to set the range of the heart rate detected at the normal time based on the detection result. In addition, for example, a camera that images the interior of the vehicle or the like in which the system is mounted is provided, and the state of the user's body captured by the camera is different from that during normal driving (for example, the user's head Detects that the position has deviated from a predetermined area for a predetermined time (for example, the time when the user's head position will return to the predetermined area if an abnormal situation has not occurred, such as 5 minutes or more). It is good also as processing to do. In this case, the predetermined time determined in step S115 (monitoring time as to whether or not a change has occurred in the user's body) is, for example, until the power is turned off after detecting that an acceleration of a predetermined value or more has occurred ( It is good to set it as time until it is judged as NO in step S111. Immediately after the occurrence of an abnormal situation such as an accident, even if the body is not affected, the body may be affected after a certain amount of time has passed.

  Further, when the controller 130 monitors whether or not a change has occurred in the user's body after detecting that an acceleration of a predetermined value or more has occurred, for example, until the power is turned off, If it is detected and automatically transmitted to an external organization (for example, a server or police station of an insurance company), there is a possibility that an accident can be prevented in advance, which is even better.

[Effects and the like of the first modification of the first embodiment]
According to the first modification of the first embodiment, when a plurality of conditions (detection of occurrence of acceleration exceeding a predetermined value and detection of acquisition of specific information from the user) are satisfied, acceleration exceeding a predetermined value An image can be recorded at a lower frequency than when an image is recorded when the error occurs. Therefore, by providing the image data recorded in the SD card 143 in the event recording process (step S119) to an external specific organization (eg, police station, fire department, Japan Automobile Federation, insurance company, etc.), the abnormal situation It is possible to more reliably reduce the verification load.

[Modification 2 of the first embodiment]
Next, a second modification of the first embodiment will be described with reference to FIG. FIG. 5 is a flowchart for explaining a second modification of the first embodiment of the control process executed by the controller 130 of the system 100.

  In the second modification of the first embodiment, after an acceleration of a predetermined value or more occurs instead of or in addition to the determination of S107 in the first embodiment (determination of whether or not the user has performed a specific action) Within a predetermined time (YES in step S125), it is determined whether or not specific information is detected from the outside of the vehicle (step S127). That is, when a plurality of conditions such as the occurrence of an acceleration equal to or greater than a predetermined value (YES in step S123) and detection of specific information from outside the vehicle within a predetermined time after the occurrence of an acceleration equal to or greater than the predetermined value And an event recording process (step S129). Note that the other processes of steps S121, S123, and S129 are the same as the processes of steps S101, S103, and S109 in the first embodiment, respectively.

  Specifically, the controller 130 generates a specific sound (for example, a specific vehicle) as specific information from the outside of the vehicle until a predetermined time elapses after an acceleration of a predetermined value or more occurs (YES in step S123). It monitors whether the sound of sirens (for example, emergency vehicles such as ambulances and police cars), loud voice of passersby, collision sound of vehicles, etc. is detected (steps S125 and S127), If it is determined that a specific sound is detected within a predetermined time after the acceleration is generated (YES in step S125) (YES in step S127), an event recording process is performed (step S129). In this case, if the specific sound is, for example, the sound of a siren of a specific vehicle, the predetermined time determined in step S125 (the monitoring time of whether or not the specific sound is detected) has an acceleration equal to or higher than a predetermined value. It is preferable to set a time taking into consideration the time from the occurrence of an abnormal condition such as an accident, for example, within 40 minutes, to the arrival of a specific vehicle, for example, within 40 minutes. Further, if the specific sound is, for example, a loud voice of a passerby or a collision sound of a vehicle, it may be a relatively short time, for example, within 3 seconds after detecting that an acceleration of a predetermined value or more has occurred.

  Further, when the acceleration equal to or more than the predetermined value is not generated (NO in step S123), the controller 130 returns to step S121. In addition, when a specific sound is not detected within a predetermined time thereafter even if an acceleration of a predetermined value or more is generated (NO in step S127), the controller 130 returns to step S121.

  In this way, acceleration of a predetermined value or more is generated as a plurality of conditions such as detection of the occurrence of acceleration of a predetermined value or more and detection of a specific sound such as a siren sound of an emergency vehicle are satisfied. Since an image can be recorded at a lower frequency than when an image is sometimes recorded, it is possible to more reliably reduce the verification load of an abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, since the timing at which each of the plurality of conditions is established is close to a certain degree (within the predetermined time described in step S125 above), the relevance of the plurality of conditions is ensured. Is done. Therefore, it is possible to more reliably reduce the verification load for abnormal situations.

  Note that the process of step S127 is not limited to the process of monitoring whether or not a specific sound is detected as specific information from the outside of the vehicle. For example, it is monitored whether or not an obstacle has approached the vehicle. It may be. The obstacle approaching the vehicle may not be a balloon, for example, but may be an abnormal situation such as an accident such as a heavy object (person, vehicle, etc.). The determination of whether or not the object is a heavy object may be detected by performing image processing on an image captured by an image capturing apparatus (for example, the camera 141) of the system 100. In this case, the predetermined time determined in step S125 (monitoring time whether or not an obstacle has approached the vehicle) is relatively short, for example, within 3 seconds after detecting that an acceleration of a predetermined value or more has occurred. Time is good.

[Effect of Modification 2 of First Embodiment]
According to the second modification of the first embodiment, an acceleration greater than a predetermined value is generated by satisfying a plurality of conditions (detection of occurrence of acceleration greater than a predetermined value and detection of specific information from outside the vehicle). The image can be recorded at a lower frequency than when the image is recorded. For this reason, by providing the image data recorded on the SD card 143 in the event recording process (step S129) to a specific external organization (eg, police station, fire department, Japan Automobile Federation, insurance company, etc.) It is possible to more reliably reduce the verification load of

[Modification 3 of the first embodiment]
Next, a third modification of the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart for explaining a third modification of the first embodiment of the control process executed by the controller 130 of the system 100.

  In the third modification of the first embodiment, an acceleration equal to or greater than a predetermined value is generated in place of or in addition to the determination of S107 (the determination of whether or not the user has performed a specific action) in the first embodiment. Within a predetermined period of time (YES in step S135), it is determined whether a change in the vehicle has been detected (step S137). That is, the occurrence of an acceleration equal to or greater than a predetermined value (YES in step S133) and the detection of a change in the vehicle (YES in step S135) after the occurrence of an acceleration equal to or greater than the predetermined value (YES in step S137) If a plurality of conditions such as “YES” are satisfied, an event recording process is performed (step S139). The other processes of steps S131, S133, and S139 are the same as the processes of steps S101, S103, and S109 in the first embodiment, respectively.

  Specifically, controller 130 monitors whether a change in the vehicle has been detected until a predetermined time has elapsed (step S135) after an acceleration equal to or greater than a predetermined value is generated (YES in step S133). (Step S137). The monitoring of whether or not the change of the vehicle is detected may be, for example, monitoring of whether or not the potential change of the vehicle is detected. This is because it is highly possible that the potential of the vehicle or the like is changed due to contact with another object when an abnormal situation occurs such as, for example, the vehicle or the like on which the system is mounted contacts another object. It pays attention. In this case, the predetermined time determined in step S135 (monitoring time as to whether or not a change in the vehicle has been detected) is a relatively short time, for example, within one second after detecting that an acceleration greater than a predetermined value has occurred. It is good to do. This is because the potential of the vehicle or the like is considered to change immediately when another object comes into contact.

  If the controller 130 determines that, for example, a change in the vehicle potential has been detected as a change in the vehicle within a predetermined time (YES in step S135) after acceleration greater than or equal to a predetermined value (YES in step S137), an event recording process is performed. (Step S139).

  When no acceleration equal to or greater than the predetermined value is generated (NO in step S133), the controller 130 returns to step S131. Further, even if an acceleration greater than or equal to a predetermined value occurs, the controller 130 does not detect a change in the vehicle, and if a predetermined time elapses from the generation of the acceleration greater than or equal to the predetermined value (NO in step S135), the process proceeds to step S131. Return.

  In this case, when a plurality of conditions such as detection of occurrence of acceleration greater than a predetermined value and detection of vehicle change are satisfied, an image is recorded when acceleration greater than the predetermined value occurs. Since images can be recorded at a lower frequency, it is possible to more reliably reduce the verification load of an abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, since the timing at which individual conditions among the plurality of conditions are established is close to a certain degree (within the predetermined time described in step S135 above), high relevance of the plurality of conditions is ensured. Is done. Therefore, it is possible to more reliably reduce the verification load for abnormal situations.

  Note that the process of step S137 is not limited to the process of monitoring whether or not a change in the vehicle has been detected. For example, it may be monitored whether or not a vehicle safety device has been activated. Examples of the vehicle safety device include an airbag device, an anti-lock / brake system, and a seat belt pretensioner device. In this case, the predetermined time determined in step S135 (monitoring time as to whether or not a change in the vehicle has been detected) is a relatively short time, for example, within 3 seconds after detecting that an acceleration greater than a predetermined value has occurred. It is good to do.

  Furthermore, the process of step S137 is performed, for example, whether or not the vehicle traveling speed has decreased from a predetermined average traveling speed (for example, 40 km / h or more) to a predetermined speed (for example, 8 km / h) or less (change in moving speed). May be monitored. Further, for example, the process of step S137 is monitored so as to monitor whether or not the vehicle travel speed has changed from a state where the vehicle traveling speed is equal to or higher than a specific average speed to a stop state and the stop state has been continued for a predetermined time or longer (eg, 5 minutes or longer). It may be. This is in view of the high possibility that the user will stop the vehicle or the like when an abnormal situation such as an accident occurs. In this case, the predetermined time determined in step S135 (the monitoring time whether or not the vehicle traveling speed is equal to or lower than the predetermined speed or zero) is, for example, 10 minutes after detecting that the acceleration equal to or higher than the predetermined value has occurred. It is preferable that the time be within 3 minutes, more preferably within 3 to 5 minutes. The change in moving speed may be monitored based on, for example, information obtained from GPS, information obtained from a vehicle speed sensor, a detection result of a brake, or the like. It should be noted that the monitoring as to whether or not the speed has become lower than the above-mentioned predetermined speed means that the traveling speed has become zero in view of the high possibility of the user stopping the vehicle etc. when an abnormal situation such as an accident occurs. However, it is preferable to monitor whether or not a predetermined speed (for example, 8 km / h) or less is taken into consideration in consideration of an error of the speed sensor.

  In addition, the process of step S137 is monitored so as to monitor whether or not the vehicle traveling speed has changed from a state where the vehicle traveling speed is equal to or higher than a specific average speed to a stopped state and the stopped state has been continued for a predetermined time or longer (eg, 3 to 5 minutes or longer). It may be. If it is 3 to 5 minutes or more, it is possible to eliminate the possibility of waiting for a signal.

[Effect of Modification 3 of First Embodiment]
According to the third modification of the first embodiment, when a plurality of conditions (detection of occurrence of acceleration greater than or equal to a predetermined value and detection of vehicle change) are satisfied, an image is displayed when acceleration greater than or equal to the predetermined value occurs. The image may be recorded less frequently than if it is recorded. For this reason, by providing the image data recorded on the SD card 143 in the event recording process (step S139) to a specific external organization (for example, police station, fire station, Japan Automobile Federation, insurance company, etc.) It is possible to more reliably reduce the verification load of

[Modification 4 of the first embodiment]
Next, a fourth modification of the first embodiment will be described with reference to FIG. FIG. 7 is a flowchart for explaining a fourth modification of the first embodiment of the control process executed by the controller 130 of the system 100.

  In the fourth modification of the first embodiment, instead of or in addition to the determination of S107 in the first embodiment (determination of whether or not the user has performed a specific action), after an acceleration of a predetermined value or more has occurred It is determined whether or not specific traveling information is detected from the vehicle within a predetermined period of time (YES in step S145) (step S147). That is, the occurrence of an acceleration equal to or greater than a predetermined value (YES in step S143) and detection of specific traveling information from the vehicle within a predetermined time after the occurrence of an acceleration equal to or greater than the predetermined value (YES in step S145) When a plurality of conditions such as YES in step S147 are satisfied, an event recording process is performed (step S149). Note that the other processes of steps S141, S143, and S149 are the same as the processes of steps S101, S103, and S109 in the first embodiment, respectively.

  Specifically, after the acceleration having a predetermined value or more is generated (YES in step S143), controller 130 determines whether or not specific traveling information from the vehicle is detected until a predetermined time passes (step S145). It is monitoring (step S147). The monitoring of whether or not the specific travel information from the vehicle is detected may be, for example, monitoring whether or not it is detected that the vehicle is traveling in the frequent accident area. The controller 130 can detect whether or not the vehicle or the like is traveling in the accident-prone area from the traveling area of the vehicle or the like that can be acquired by the GPS receiver 140, for example. For example, the information on the accident frequently occurring area may be stored in advance in the system, or the controller 130 may acquire it from the outside (for example, a server of an external organization such as an insurance company or a police station).

  In addition, the predetermined time determined in step S145 (for example, the monitoring time of whether or not the specific travel information from the vehicle is detected) is, for example, within 10 seconds after detecting the occurrence of the acceleration equal to or more than the predetermined value. For example, it is good to set it as the time required for detection of a traveling area such as a vehicle that can be acquired by the GPS receiver 140.

  In the above, after the acceleration equal to or more than the predetermined value is generated (YES in step S143), whether or not the specific traveling information from the vehicle is detected until the predetermined time elapses (step S145) Instead of this, while detecting specific traveling information from the vehicle, it may always be monitored whether or not an acceleration of a predetermined value or more has occurred.

  The event recording process is performed when the controller 130 satisfies both of the occurrence of the acceleration equal to or more than the predetermined value (YES in step S143) and the detection of specific traveling information from the vehicle (YES in step S147). (Step S149).

  Further, when the acceleration equal to or more than the predetermined value is not generated (NO in step S143), the controller 130 returns to step S141. Further, the controller 130 does not detect specific travel information from the vehicle even if acceleration of a predetermined value or more occurs, or generates acceleration of a predetermined value or more even if it detects specific travel information from the vehicle. Is not detected, the process returns to step S141.

  In this way, acceleration of a predetermined value or more is generated by the establishment of a plurality of conditions such as detection of the occurrence of acceleration of a predetermined value or more and detection of the vehicle traveling in a frequent accident area Since an image can be recorded at a lower frequency than when an image is sometimes recorded, it is possible to more reliably reduce the verification load of an abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. Further, since the timing at which each condition among the plurality of conditions is satisfied is performed at a timing close to a certain extent (within the predetermined time described in step S145 described above), the level of relevance of the plurality of conditions is secured Is done. Therefore, it is possible to more reliably reduce the load of verification of abnormal situations.

  In addition, the process of step S147 is not limited to the process of monitoring whether the vehicle is traveling in the frequent accident area, for example, whether the vehicle is traveling in the frequent accident time zone (for example, around 16-18 o'clock) You may monitor it.

[Effect of Modification 4 of First Embodiment]
According to the fourth modification of the first embodiment, when a plurality of conditions (detection of occurrence of acceleration greater than or equal to a predetermined value and detection of vehicle travel information) are established, acceleration greater than or equal to a predetermined value occurs. Images may be recorded less frequently than when the images are recorded. For this reason, by providing the image data recorded on the SD card 143 in the event recording process (step S149) to a specific external organization (for example, police station, fire station, Japan Automobile Federation, insurance company, etc.) It is possible to more reliably reduce the verification load of

[Modification 5 of the first embodiment]
Next, a fifth modification of the first embodiment will be described with reference to FIG. FIG. 8 is a flowchart for explaining a fifth modification of the first embodiment of the control process executed by the controller 130 of the system 100.

  In the fifth modification of the first embodiment, fulfillment of a plurality of conditions other than the condition of detection of the occurrence of acceleration equal to or more than a predetermined value is set as a condition for performing the event recording process. In other words, even if a single condition is satisfied, even if the event recording processing frequency cannot be reduced compared to the conventional case where the event recording processing is performed when acceleration of a predetermined value or more occurs, a plurality of conditions It is noted that the frequency of performing event recording processing can be made lower than in the prior art by making the establishment of the event a condition for event recording processing. The processes of steps S151 and S159 are the same as the processes of steps S101 and S109 in the first embodiment, respectively.

  For example, after the power is turned on (YES in step S151), the controller 130 determines whether the user performs a specific action as the first condition (step S153), and the user performs the specific action. After determining that it has been performed (YES in step S153), it is monitored whether the second condition is satisfied, that is, whether specific information is detected from the user (step S157), until a predetermined time passes (step S155). ). If both conditions that the user who is the first condition has performed a specific action and specific information is detected from the user which is the second condition are satisfied within a predetermined time (YES in step S153) Also, an event recording process is performed (YES in step S155 and YES in step S157) (step S159).

  The order of the determination as to whether or not the user has performed a specific action (step S153) and the determination as to whether or not specific information has been detected from the user (step S157) is not limited to the order described above. After determining that specific information has been detected, whether or not specific information has been detected from the user may be monitored until a predetermined time has elapsed (YES in step S155).

  In addition, if the controller 130 does not satisfy the conditions of both the user performing the specific action and the detection of the specific information from the user within a predetermined time (NO in step 153, NO in step S155), The process returns to step S151. In addition, if any one of the condition that the user performed a specific action and that the specific information is detected from the user is satisfied, and if the predetermined time has not elapsed since the condition is satisfied (step S155 NO), return to step S153.

  Note that the predetermined time determined in step S155 (the monitoring time whether or not the second condition is satisfied) differs depending on the second condition. For example, if the second condition is, for example, detection that the user has operated the operation button 124, the user operates the operation button 124, for example, within 20 minutes after the first condition is established. It is good to be able to secure a certain amount of time. If the second condition is, for example, detection that the user's heart rate is out of a predetermined range (e.g., heart rate 100 or more, or measurement impossible), the first condition is satisfied. For example, the time from when the external power supply is turned off to the time when it is assumed that the user's body may be affected. Also, if the second condition is, for example, detection of a specific sound (for example, the sound of a siren of a specific vehicle (for example, an emergency car such as an ambulance or police car), a loud voice of a passerby, a collision sound of a vehicle, etc.) For example, it may be a time that takes into account the time from when an abnormal state such as an accident occurs, for example, within 40 minutes after the first condition is satisfied, until the specific vehicle arrives. Further, when the second condition is, for example, detection of a change in the potential of the vehicle, it is considered that the potential of the vehicle or the like changes immediately when another object comes into contact. It is preferable that the time is relatively short, for example, within one second. Also, if the second condition is, for example, detection that the vehicle is traveling in an accident-prone area, for example, within 10 seconds after the first condition is established, for example, by the GPS receiver 140 It is good to set it as the time required for detection of a travel area of a vehicle etc. which can be acquired. As described above, the predetermined time determined in step S155 (the monitoring time of whether the second condition is satisfied) may be set to a time in which the second condition may be established.

  In this way, acceleration equal to or greater than a predetermined value is generated when a plurality of conditions such as detection that the user has performed a specific action and detection of acquisition of specific information from the user are satisfied. Since an image can be recorded at a lower frequency than when an image is sometimes recorded, it is possible to more reliably reduce the verification load of an abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. In addition, since the timing at which each condition among the plurality of conditions is satisfied is performed at a timing close to a certain extent (within a predetermined time that varies depending on the second condition), the height of the relevance of the plurality of conditions is ensured Is done. Therefore, it is possible to more reliably reduce the load of verification of abnormal situations.

  Further, the combination of the process performed in step S153 and the process performed in step S157 is not limited to the combination of detection of the user performing a specific action and detection of specific information from the user. For example, the above combination includes detection of the user performing a specific action and detection of specific information from outside the vehicle, detection of the user performing specific action, detection of a change in the vehicle, and the user Detection of performing a specific action and detection of specific information from outside the vehicle, detection of acquisition of specific information from the user, detection of specific information from the outside of the vehicle, detection of specific information from the user And detection of changes in vehicles, detection of specific information from users and detection of specific information from outside vehicles, detection of specific information from outside vehicles, detection of changes in vehicles, detection of specific information from outside vehicles Variations such as detection and detection of specific information from outside the vehicle, and detection of changes in the vehicle and detection of specific information from the outside of the vehicle

  Furthermore, in the fifth modification of the first embodiment, the establishment of a plurality of conditions other than the condition for detecting the occurrence of an acceleration equal to or greater than a predetermined value is a condition for performing the event recording process. Is not limited to the satisfaction of the two conditions. For example, even if three or more conditions such as detection of the user performing a specific action, detection of specific information from the user, detection of specific information from the outside of the vehicle, etc. are satisfied, Since an image can be recorded at a lower frequency than when an image is recorded when acceleration equal to or greater than a predetermined value occurs, it is possible to more reliably reduce the verification load of an abnormal situation. The combination of the three or more conditions includes, for example, the detection of the user performing a specific action, the detection of specific information from the user, the detection of specific information from the outside of the vehicle, and the detection of a change in the vehicle. And a combination of any three or more conditions among a plurality of conditions such as detection of specific information from the outside of the vehicle.

[Effect of Modification 5 of First Embodiment]
According to the fifth modification of the first embodiment, when a plurality of conditions other than the condition for detecting the occurrence of an acceleration greater than or equal to a predetermined value are satisfied, an image is recorded when an acceleration greater than or equal to the predetermined value occurs. Images can be recorded less frequently than usual. Therefore, by providing the image data recorded in the SD card 143 in the event recording process (step S159) to an external specific organization (for example, a police station, a fire department, the Japan Automobile Federation, an insurance company, etc.) It is possible to more reliably reduce the verification load of In particular, even if the frequency of performing the event recording process can not be reduced compared to the conventional case where the event recording process is performed when acceleration exceeding a predetermined value is generated, a plurality of conditions can be achieved only by the establishment of a single condition. As a condition for event recording processing, it is possible to reduce the frequency of performing event recording processing. However, it is not excluded to set one of the plurality of conditions as a condition that the event recording process is performed less frequently than in the past only when a single condition is satisfied.

[Effects of First Example and Modifications 1 to 5 of First Example]
According to the first embodiment and the first to fifth modifications of the first embodiment, the event recording process is performed less frequently than the conventional case in which the event recording process is performed when acceleration of a predetermined value or more occurs. It becomes possible. When one of a plurality of conditions is the occurrence of acceleration of a predetermined value or more, a conventionally used acceleration sensor can be used, and an event recording process for recording event recording image data is performed. It is possible to reduce the frequency of operation at low cost.

  Also, the event recording process (step S109, step S119, step S129, step S139, step S149, step S159) of the first embodiment and the first to fifth modifications of the first embodiment is recorded in the SD card 143 The received image data may be sent by mail or the like to an external specific organization (for example, a police station, a fire department, the Japan Automobile Federation, an insurance company, etc.). However, if the controller 130 performs processing for transmitting image data recorded in the above event recording processing to a specific external organization, image data can be provided in a timely manner without any trouble. It becomes.

  When the controller 130 performs processing for transmitting the image data recorded in the event recording processing to a specific external organization, the system may confirm with the user whether or not the transmission processing may be performed. . For example, the system may perform confirmation by voice such as “Do you want to send the recorded image?” With the interactive UI. The system may recognize by voice the response such as “Yes / No” by the user, and when there is a response “Yes”, the system may transmit an image to an insurance company, a police station or the like.

  Further, when the controller 130 performs processing for transmitting the image data recorded in the event recording processing to a specific external organization, the user may be prompted to perform a transmission operation. For example, the system may prompt the transmission operation by voice such as “If a drive recorder with a data transmission function is attached, please press the operation button to transmit the image if a drive recorder with a data transmission function is mounted”. The system may transmit the image to an insurance company, a police station or the like when the user presses the transmission button.

  Also, when the controller 130 performs processing for transmitting image data recorded in the event recording processing to a specific external organization, the sensitivity (predetermined value) of the acceleration sensor 144 applied when performing event recording The sensitivity (predetermined value) of the acceleration sensor 144 applied when the event-recorded image is transmitted to a specific external engine may be set to a different value. Specifically, for example, the sensitivity (predetermined value) applied when transmitting an image may be set higher than the sensitivity (predetermined value) of the acceleration sensor 144 applied when performing event recording. Furthermore, the sensitivity (predetermined value) applied when transmitting an image is, for example, about 1.5 G, more preferably, for example, 3.0 G or more (acceleration corresponding to the occurrence of an obvious accident), and when recording an event. The sensitivity (predetermined value) of the applied acceleration sensor 144 may be set to, for example, about 1 G. With such a setting, it is possible to lower the frequency of transmitting an image rather than the frequency of image recording, and to reduce the load of verification of an abnormal situation in an insurance company etc. more reliably. .

  The event recording process (step S109, step S119, step S129, step S139, step S149, step S159) of the first embodiment and the first to fifth modifications of the first embodiment is, for example, as follows. The constantly recorded image data recorded in the first recording area of the SD card 143 is read out, and before and after the first event occurrence time (steps S103, S113, S123, S133, S143, S153) each for a predetermined time (for example, 20 seconds before and after) Processing for cutting out the image data of (1) and recording it as event recording image data in the second recording area of the SD card 143, and the like.

  In the event recording process (step S109, step S119, step S129, step S139, step S149, step S159) of the first embodiment and the first to fifth modifications of the first embodiment, the image data is SD However, the present invention is not limited to this, and it may be recorded in the system RAM 133 or in both the SD card 143 and the system RAM 133. Furthermore, recording may be performed in a recording area outside the system.

  Also, image data is recorded in the event recording process (step S109, step S119, step S129, step S139, step S149, step S159) of the first embodiment and the first to fifth modifications of the first embodiment. In this case, it is better to rank the possibility that abnormal data is included in the data to be recorded.

  Further, in the first embodiment and the first to fifth modifications of the first embodiment, the system can be set to a personal mode in which individual performance settings can be made and a business mode in which business performance settings can be made. It is desirable to have a function that can switch the performance of the system. Thereby, the performance of the system can be arbitrarily set according to the user of the system. For example, when the personal mode is set, the image quality etc. of the video is set to the average (medium) image quality, or the image transmission to the outside is performed through the normal line etc., and the business mode is set. Then, the image quality or the like of the video may be set to a high image quality, or image transmission to the outside may be performed via a high-speed line such as LTE (Long Term Evolution) (registered trademark).

  Further, in the first embodiment and the first to fifth modifications of the first embodiment, the system has a function of describing probability information indicating a probability that an abnormal situation is reflected in the image. Good. The “probability information indicating the probability that an abnormal situation appears” may be described in an image, for example, as a telop. In addition, when it is detected that the user does not move for more than a predetermined time after the vehicle is at a standstill and an acceleration equal to or more than a predetermined value is generated, event recording is performed and the recorded image is automatically transmitted to the outside Good. In addition, after the conditions for event recording processing are complete, the recorded image is always sent to the outside (for example, a server such as a police station or an insurance company) as an image of the situation after the accident (attitude of oneself or the other party, the situation such as police). It is good to do.

[Second Embodiment]
Next, with reference to FIG. 9, a second embodiment of control processing executed by the controller 130 will be described. FIG. 9 is a flow chart for explaining a second embodiment of control processing executed by the controller 130 of the system 100.

  The controller 130 determines whether the external power supply is ON (step S201), and when the external power supply is ON (YES in step S201), the processing of step S203 to step S205 is performed. Although not shown in FIG. 9, when power is supplied to the system 100 and the external power supply is turned on, the controller 130 outputs the image data (always recorded image data) input from the camera 141 to the first of the SD card 143. A constant recording process to always record in the recording area is performed. Since the constant recording process is a process of continuing recording as long as power is supplied to the system 100, the process is performed concurrently with the process of, for example, steps S203 to S205 described later.

  In step S201, when the supply of power to the system 100 is started and the external power supply is turned on (in the case of YES), the controller 130 determines whether the user has performed a specific action (step S203).

  Specifically, the controller 130 constantly monitors whether or not an operation of the operation button 24 (see FIG. 1) is detected as a specific action by the user as long as the power is on. If the controller 130 determines that the operation button 24 has been operated (YES in step S203), it performs an event recording process (step S205). This is because if the user recognizes that the operation button 24 should be operated when an abnormal situation such as an accident occurs, the abnormal situation occurs when the operation button 24 is operated by his / her own intention. It is in view of the high possibility of the occurrence.

  In this way, an independent and highly reliable condition such as the detection of the operation of the operation button 24 is established, so that an image is displayed at a lower frequency than when an image is recorded when acceleration of a predetermined value or more occurs. Since the information can be recorded, it is possible to more reliably reduce the verification load of the abnormal situation. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. Further, by recording an image when a single condition is satisfied, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of parts of the system.

  The system may be provided with a function for prompting the user to operate the operation button 24 when an abnormal situation such as an accident occurs.

  In view of the possibility that an erroneous operation of the operation button 24 may occur, it is preferable that the user can cancel the operation of the operation button 24. If the user operates the operation button 24 and then cancels the operation, the event recording process may not be performed, or the recorded image data may be deleted after the event recording process is performed.

  In addition, it is preferable to provide the system with a function for determining an erroneous operation of the operation button 24. For example, in view of the high possibility that the user will hit the operation button 24 continuously when an abnormal situation occurs, whether the operation button 24 has been hit continuously more than a predetermined number of times (for example, three times or more within 5 seconds) within a predetermined time Whether or not the operation is an error may be determined depending on whether or not it is. In this case, for example, if the operation button 24 is continuously hit a predetermined number of times or more within a predetermined time, the operation is recognized as a correct operation, and if it is not continuously hit a predetermined number of times or more within a predetermined time, it is recognized as an erroneous operation It is good to do so. In addition, when the operation button 24 is operated once, it is preferable that the system sends an announcement such as “Please push the operation button again if an abnormal situation such as an accident has occurred”. In this case, if the user operates the operation button 24 again within a predetermined time (for example, within 10 seconds), the system recognizes the first operation as a correct operation, and the user operates the operation button 24 within the predetermined time. If not, the system may recognize the previous operation as an erroneous operation.

  Further, the process of step S203 for determining whether or not the user has performed a specific action is not limited to the process for determining whether or not the operation of the operation button 24 (see FIG. 1) is detected. A process may be performed to detect that communication has been made from a specific device (for example, a smartphone or a tablet) owned by the user to an external specific organization (for example, a police station, a fire department, the Japan Automobile Federation, an insurance company, etc.). It is good to register the telephone number etc. of a specific organization in the system. In addition, it is preferable to record a history (for example, date and time and contents of conversation when communication is made) when communication is performed from a specific device owned by the user to a specific external organization.

[Effects and the like of the second embodiment]
According to the second embodiment, by recording an image triggered by the establishment of a single condition such as a specific action by a user, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of system components. It becomes possible.

[Modifications 1 to 3 of the second embodiment]
Next, Modifications 1 to 3 of the second embodiment will be described with reference to FIGS. 10 to 12. The first to third modifications of the second embodiment are different from the second embodiment in a part of the processes executed by the controller of the system shown in FIG.

[Modification 1 of the second embodiment]
First, a first modification of the second embodiment will be described with reference to FIG. FIG. 10 is a flowchart for explaining a first modification of the second embodiment of the control process executed by the controller 130 of the system 100.

  In the first modification of the second embodiment, whether or not specific information from the user is detected instead of the determination in S203 (the determination as to whether the user has performed a specific action) in the second embodiment Is determined (step S213). When the condition that the specific information from the user is detected is satisfied, the event recording process is performed (step S215). The other processes of steps S211 and S215 are the same as the processes of steps S201 and S205 in the second embodiment, respectively.

  Specifically, after the power is turned on (YES in step S211), the controller 130 determines whether or not a change of a predetermined value or more has occurred in the user's body as specific information from the user. Is always monitored as long as is ON (step S213). If it is determined that a change of a predetermined value or more has occurred in the user's body (YES in step S213), event recording processing is performed (step S215).

  Whether or not a change of a predetermined value or more has occurred in the user's body is detected by detecting the user's heart rate by providing a sensor that can measure the user's blood flow, for example, on the steering wheel of a vehicle or the like in which the system is mounted. Alternatively, it may be a process for detecting that the heart rate is out of a predetermined range (for example, the heart rate is 100 or more or measurement is impossible). In addition, the system is equipped with a camera that captures, for example, the inside of a vehicle of the vehicle, and the state of the user's body imaged by the camera is different from that during normal driving (for example, For example, the position may deviate from a predetermined region for a predetermined time or more.

[Effects of Modification 1 of Second Embodiment, etc.]
According to the first modification of the second embodiment, an image is recorded when an acceleration exceeding a predetermined value is generated by satisfying a single reliable condition such as detecting specific information from the user. Since an image can be recorded at a lower frequency than the case, it is possible to more reliably reduce the verification load of an abnormal situation. Specifically, for example, an insurance company that has received an image from the system can reduce a verification load as to whether or not the image is an image of an abnormal situation such as an accident. Further, by recording an image when a single condition is satisfied, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of parts of the system. Furthermore, by detecting specific information from the user, such as the user's heart rate, as an event recording process condition, it is possible to reliably record an image even when the user is not conscious. It becomes.

[Modification 2 of the second embodiment]
Next, a second modification of the second embodiment will be described with reference to FIG. FIG. 11 is a flowchart for explaining a second modification of the second embodiment of the control process executed by the controller 130 of the system 100.

  In the second modification of the second embodiment, whether or not information from the outside of the vehicle has been detected, instead of the determination in S203 in the second embodiment (determination of whether or not the user has performed a specific action). It judges (step S223). If the condition that information from the outside of the vehicle is detected is satisfied, an event recording process is performed (step S225). The other processes of steps S221 and S225 are the same as the processes of steps S201 and S205 in the second embodiment, respectively.

  Specifically, after the power is turned on (YES in step S221), the controller 130, for example, determines whether an obstacle approaches the vehicle as information from the outside of the vehicle, as long as the power is turned on. When monitoring is always performed (step S223) and it is determined that the distance from the obstacle approaching the vehicle has become zero (that is, a collision has occurred) (YES in step S223), event recording processing is performed (step S225).

  Monitoring of whether or not an obstacle has approached the vehicle may be performed, for example, by providing a distance measuring sensor on the vehicle and determining whether or not an object has approached using the distance measuring sensor. Further, for example, a camera that captures an image of the surroundings of the vehicle may be mounted on the vehicle, and the captured image of the camera may be analyzed. However, it is better to determine whether the obstacle approaching the vehicle is not a balloon or the like, for example, a heavy object. The determination of whether or not the object is a heavy object may be detected by performing image processing on an image captured by an image capturing apparatus (for example, the camera 141) of the system 100. In addition, the distance between the vehicle position and the surrounding heavy objects is a predetermined distance using an image of the vehicle seen from above, such as an around view image generated based on images of a plurality of cameras etc. May be detected. Whether it is “a heavy object capable of causing an accident on an object such as a vehicle” or not is preferably determined using a condition that the height of an object around the vehicle is not less than a predetermined value. Whether or not the height of an object around the vehicle is a predetermined value or more may be detected based on an image of at least one of a microwave sensor or a camera. Further, the “predetermined” height of the object around the vehicle is preferably higher than the vehicle height. This is because an object lower than the vehicle height can pass under the vehicle.

[Effects of Modification 2 of Second Embodiment, etc.]
According to the second modification of the second embodiment, an image is recorded when an acceleration greater than a predetermined value occurs because a reliable condition such as the detection of information from outside the vehicle is established. Since the image can be recorded at a lower frequency than the case where the error occurs, it is possible to more reliably reduce the verification load of the abnormal situation. Specifically, for example, an insurance company that has received an image from the system can reduce a verification load as to whether or not the image is an image of an abnormal situation such as an accident. Further, by recording an image when a single condition is satisfied, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of parts of the system.

[Modification 3 of the second embodiment]
Next, a third modification of the second embodiment will be described with reference to FIG. FIG. 12 is a flowchart for explaining a third modification of the second embodiment of the control process executed by the controller 130 of the system 100.

  In Modification 3 of the second embodiment, instead of the determination in S203 in the second embodiment (determination of whether or not the user has performed a specific action), it is determined whether or not a change in the vehicle has been detected. (Step S233). If the condition that a change in the vehicle is detected is satisfied, an event recording process is performed (step S235). The other processes of steps S231 and S235 are the same as the processes of steps S201 and S205 in the second embodiment, respectively.

  Specifically, after the power is turned on (YES in step S231), the controller 130, for example, determines whether the potential of the vehicle (for example, the vehicle body) has changed by a predetermined value or more as the change of the vehicle. As long as it is ON, it is constantly monitored (step S233). If it is determined that the potential of the vehicle has changed by a predetermined value or more (YES in step S233), an event recording process is performed (step S235).

  For monitoring whether or not the potential of the vehicle has changed, for example, a voltmeter may be connected to the vehicle body (for example, the hood or bumper of the vehicle) to measure the potential of the vehicle body (for example, the hood or bumper). .

  In this way, an independent and highly reliable condition such as a change in the electric potential of the vehicle is established, so that an image is recorded at a lower frequency than when an image is recorded when acceleration of a predetermined value or more occurs. Therefore, it is possible to more reliably reduce the verification load for abnormal situations. Specifically, for example, it is possible for an insurance company or the like that has received an image from the system to reduce the verification load as to whether or not the image is an image of an abnormal situation such as an accident. Further, by recording an image when a single condition is satisfied, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of parts of the system.

  Note that the process of step S233 is not limited to the process of detecting whether or not the potential of the vehicle has changed by a predetermined value or more. For example, the process of detecting the deformation of the vehicle may be used. Alternatively, a predetermined sensor may be attached to the steering handle, and the sensor may be detected to be detached (dropped) from the steering handle. Furthermore, it is good also as a process which detects whether the safety device of the vehicle act | operated. Examples of the vehicle safety device include an air bag, an anti-lock / brake system, and a seat belt pretensioner device. In addition, during the operation of the system, a portion of the system's camera (camera that captures the interior of the vehicle) that exceeds a predetermined ratio has moved from the position before the accident due to some object (for example, a deployed airbag, the impact of the accident) It is good also as a process which detects having covered with the object in a vehicle etc.). In this process, if the field of view is suddenly covered with white, it is likely that the field of view of the camera is covered with a deployed airbag, so it is determined whether the field of view is suddenly covered with white. You may

  The state of the airbag can be detected by monitoring the communication contents of the CAN mounted on the vehicle, for example. Note that, based on the communication contents of CAN (Controller Area Network), for example, it is possible to detect an airbag deployment, a rear collision, an airbag system abnormality, a safing, a front collision, a side collision, and the like. Further, the state of the air bag may be detected by accessing the air bag ECU. Moreover, the state of the airbag is monitored by monitoring the operation sound of the airbag (for example, monitoring of a loud explosion sound of 150 db to 170 db in 100 ms or less), monitoring the change in air pressure accompanying the operation of the airbag, or being mounted on a vehicle. It is good to detect by OBD (fault diagnosis device) etc.

[Effects of Modification 3 of Second Embodiment, etc.]
According to the third modification of the second embodiment, by recording an image triggered by the detection of a change in the vehicle, for example, it is possible to reduce the verification load of an abnormal situation while suppressing the number of parts of the system. It becomes possible.

[Effects of Second Example and Modifications 1 to 3 of Second Example]
According to the second embodiment and the first to third modifications of the second embodiment, the event recording process is performed less frequently than the conventional case in which the event recording process is performed when acceleration of a predetermined value or more occurs. It becomes possible.

  The image data recorded on the SD card 143 in the event recording process (step S205, step S215, step S225, step S235) of the second embodiment and the first to third modifications of the second embodiment is as follows. The SD card 143 may be sent to a specific external organization (for example, a police station, a fire station, the Japan Automobile Federation, an insurance company, etc.) by mail or the like. However, if the controller 130 performs the process of transmitting the image data recorded in the event recording process to a specific external organization, the image data can be provided in a timely manner without trouble. It becomes.

  The event recording processes (step S205, step S215, step S225, step S235) of the second embodiment and the first to third modifications of the second embodiment are, for example, the first of the SD card 143, respectively. Is recorded in the recording area, and image data of a predetermined time (for example, every 20 seconds before and after) before and after the event occurrence time (steps S203, S213, S223, and S233) is cut out to record the event recording image data. For example, a process of recording in the second recording area of the SD card 143.

  In the event recording process (step S205, step S215, step S225, step S235) of the second embodiment and the first to third modifications of the second embodiment, image data is recorded on the SD card 143. However, the present invention is not limited to this, and it may be recorded in the system RAM 133 or may be recorded in both the SD card 143 and the system RAM 133. Furthermore, recording may be performed in a recording area outside the system.

  Also, data to be recorded when recording image data in the event recording process (step S205, step S215, step S225, step S235) of the first to third modifications of the second embodiment and the second embodiment It is recommended to rank the possibility that abnormal situations are reflected in

  In the second embodiment and the first to third modifications of the second embodiment, the system includes a personal mode capable of setting performance for individuals and a business mode capable of setting performance for business use. It is desirable to have a function that can switch the performance of the system. Thereby, the system performance can be arbitrarily set according to the user of the system. For example, when the personal mode is set, the image quality etc. of the video is set to the average (medium) image quality, or the image transmission to the outside is performed by a normal line etc. In this case, the image quality or the like of the video may be set to a high quality, or the image transmission to the outside may be performed through a high speed circuit such as Long Term Evolution (LTE) (registered trademark).

[Third embodiment]
Next, with reference to FIG. 13, a third example of control processing executed by the controller 130 will be described. FIG. 13 is a flowchart for explaining a third example of the control process executed by the controller 130 of the system 100. In the third embodiment, when a possibility of an accident of another vehicle is detected, data is provided to the outside (for example, a server of a specific organization such as an insurance company or a police station).

  The controller 130 determines whether or not the external power source is ON (step S301). When the external power source is ON (YES in step S301), the controller 130 performs the processes in steps S303 to S307. Although not shown in FIG. 14, when power is supplied to the system 100 and the external power supply is turned on, the controller 130 stores the image data (always recorded image data) input from the camera 141 in the first SD card 143. A constant recording process for always recording in the recording area is performed. Since the constant recording process is a process of continuing recording as long as power is supplied to the system 100, the process is performed concurrently with the process of, for example, steps S303 to S307 described later.

  In step S301, when the supply of power to the system 100 is started and the external power supply is turned on (in the case of YES), the controller 130 determines whether or not there is a possibility of an accident in another vehicle. Judgment is made (step S303).

  Specifically, after the power is turned on (YES in step S301), the controller 130 determines whether or not the possibility of an accident of another vehicle has been detected, for example, the operation button 24 (see FIG. 1). ) Is always monitored as long as the power is on (step S303). If it is determined that the operation button 24 is operated (YES in step S303), an event recording process is performed (step S305). If the user recognizes that the operation button 24 should be operated when seeing that an abnormal situation such as an accident has occurred in another vehicle, the operation button 24 is operated by his / her own intention. In this case, it is considered that there is a high possibility that an abnormal situation has occurred in another vehicle.

  After performing the event recording process (step S305), the controller 130 thereafter transmits the information (image or the like) recorded in step S305 to a predetermined external server (step S307). Examples of the predetermined server include an insurance company server and a police station server.

  Note that the process of step S303 is not limited to the process of detecting whether or not the operation button 24 has been operated, and for example, from a specific device (for example, a smartphone or a tablet) owned by the user to an external specific institution (for example, , Police station, fire department, Japan Automobile Federation, insurance company, etc.) may be detected. In this case, a telephone number of a specific institution should be registered in the system. In addition, it is more preferable to record a history (for example, date and time and contents of conversation at the time of communication) when communication is performed from a specific device owned by the user to a specific external organization.

  Further, the process of step S303 may be a process of detecting whether or not a specific sound (for example, a loud sound of a predetermined value or higher, a collision sound of an automobile, or the like) has been detected. Furthermore, when the vehicle is traveling in an accident-prone area, or when the vehicle is traveling in an accident-prone time zone, the event may be recorded constantly.

  Note that in the event recording process performed in step S305, it is preferable to label information on the date and place of imaging and the image. Such labeling makes it easy to search for an image.

[Effects and the like of the third embodiment]
According to the third embodiment, when it is detected that an abnormal situation such as an accident may have occurred in another vehicle, data is externally transmitted (for example, a server of a specific organization such as an insurance company or a police station). By providing this, it is possible to contribute to the verification of an accident (an abnormal situation) of another vehicle outside, and to reduce the verification load of the abnormal situation. Moreover, if the number of vehicles equipped with the system according to the third embodiment increases, more effective data contributes to the verification of accidents of other vehicles, and the accuracy of verification of accidents of other vehicles is further enhanced. Can do.

  In the event recording process (step S305) of the third embodiment, the image data is recorded on the SD card 143. However, the present invention is not limited to this, and the image data may be recorded on the system RAM 133 or the SD card. 143 and RAM 133 of the system. Furthermore, recording may be performed in a recording area outside the system (for example, a specific external organization).

  In the event recording process (step S305) of the third embodiment, for example, the constantly recorded image data recorded in the first recording area of the SD card 143 is read out, and predetermined before and after the event occurrence time (step S303). For example, image data of time (for example, 20 seconds before and after) is cut out and recorded as event recording image data in the second recording area of the SD card 143.

  Further, when recording image data in the event recording process (step S305) of the third embodiment, it is preferable to rank the possibility that an abnormal situation is included in the data to be recorded.

Modification of Third Embodiment
Next, with reference to FIG. 14, a modification of the third embodiment of the control process executed by the controller 130 will be described. FIG. 14 is a flowchart for explaining a modification of the third embodiment of the control process executed by the controller 130 of the system 100. The modification of the third embodiment is applicable when a request for data specifying a date, time, and location is received from a server of a specific external organization (for example, police station, fire department, insurance company, etc.). It is intended to transmit data to the above-mentioned external specific organization.

  Specifically, the controller 130 determines whether or not the external power supply is ON (step S311). When the external power supply is ON (YES in step S311), the controller 130 performs the processes of steps S313 to S317. . Although not shown in FIG. 14, when power is supplied to the system 100, the controller 130 always records the image data (always recorded image data) input from the camera 141 in the first recording area of the SD card 143. A continuous recording process is performed. Since this continuous recording process is a process that continues recording as long as power is supplied to the system 100, for example, it is performed in parallel with processes such as step S313 to step S317 described later. Note that the controller 130 may record the date and location information of the imaging by labeling the image in the continuous recording process. Such labeling makes it easy to search for an image.

  In step S311, when the supply of power to the system 100 is started and the external power supply is turned on (in the case of YES), the controller 130 is, for example, a specific external organization (for example, a police station, a fire department, an insurance company, etc.). It is determined whether or not there is an inquiry from a server or the like (step S313).

  For example, when the controller 130 determines that there is an inquiry from a server of a specific external organization (for example, a police station, a fire department, an insurance company, etc.) (YES in step S313), the corresponding data is stored in the SD card 143. It is determined whether or not data is recorded in one recording area (step S315). For example, if the inquiry in step S313 is a request for data specifying, for example, the date and location, the controller 130 indicates that the labeled data corresponding to the specified date and location is the first recording area of the SD card 143. It is searched whether or not it is recorded. “Corresponding to the designated date and time and location” means that the time corresponds to the designated date and time and location, the time is a difference of 4 to 5 minutes as the running time, and the location is 1 to 2 km, for example. There may be differences. For example, if data corresponding to an inquiry from a server of a specific external organization (for example, a police station, a fire department, an insurance company, etc.) is recorded in the first recording area of the SD card 143 (Step S315). YES), the corresponding data is cut out and transmitted to the server of the inquiry source (for example, police station, fire department, insurance company, etc.). When the data corresponding to the inquiry is not recorded in the first recording area of the SD card 143, the above inquiry may be ignored, or information indicating that the corresponding data is not recorded is obtained from the inquiry source. You may make it transmit to.

  In addition, in the continuous recording process, the controller 130 records, for example, information such as a characteristic shape of another vehicle or a color of another vehicle on an image instead of or in addition to the information on the date and time of imaging. You may do it. Searching for an image is facilitated by increasing the amount of information labeled on the image. Information such as the characteristic shape of the other vehicle and the color of the other vehicle can be obtained by analyzing the image captured by the camera 141.

[Effects of Modification of Third Embodiment]
According to a modification of the third embodiment, an image of a possibility that an abnormal situation such as an accident has occurred in another vehicle is read and transmitted to a specific external engine, thereby verifying the accident of the other vehicle. It can be useful for When the inquired high reliability condition is satisfied, the image can be recorded at a lower frequency than when the acceleration of a predetermined value or more occurs, so the verification load for abnormal situations can be more reliably ensured. It is possible to reduce it.

[Effects of Modifications of Third Embodiment and Third Embodiment]
According to the third embodiment and the modification of the third embodiment, when it is detected that an abnormal situation such as an accident may have occurred in another vehicle, an external (for example, an insurance company or a police station) By providing data to or sending data to a specific organization's server, etc., it is possible to contribute to the verification of accidents (abnormal situations) of other vehicles externally and to reduce the burden of verification of abnormal situations It becomes. In particular, an event recording process is performed when an acceleration of a predetermined value or more occurs in the host vehicle or the like in which the system is installed, and an abnormal situation is detected using an image recorded by the event recording process without providing an image or the like from another company. Compared with the conventional case where the verification is performed, it is possible to reduce the verification load of the abnormal situation. Further, if the number of vehicles equipped with the system according to the third embodiment or the modified example of the third embodiment increases, the effective data contributing to the verification of accidents of other vehicles increases, The accuracy of verification can be further increased.

  Further, in the third embodiment and the modified example of the third embodiment, the system is configured between a personal mode capable of setting performance for individuals and a business mode capable of setting performance for business. It is good to have the function which can switch the performance of the system. Thereby, the system performance can be arbitrarily set according to the user of the system. For example, when the personal mode is set, the image quality etc. of the video is set to the average (medium) image quality, or the image transmission to the outside is performed by a normal line etc. In this case, the image quality or the like of the video may be set to a high quality, or the image transmission to the outside may be performed through a high speed circuit such as Long Term Evolution (LTE) (registered trademark).

[Other Examples]
In addition to the event recording described in at least one of the embodiments, it is preferable to have a function (herein referred to as an acceleration event recording function) for recording an image picked up when an acceleration of a predetermined level or more is generated as in the conventional case. , “A function for recording a captured image in a predetermined recording area triggered by a specific condition that can be satisfied at a lower frequency than when a predetermined or higher acceleration occurs” is the acceleration event recording function. It is particularly preferable to use a function that records an image captured in a predetermined recording area when a specific condition that can be satisfied at a frequency lower than the “predetermined acceleration” that is the recording condition in FIG. The “acceleration above a predetermined value”, which is a recording condition by the acceleration event recording function, may be configured to be set based on an instruction from a user or the like, and in this case, in particular, from the default acceleration in the setting. In particular, it is particularly preferable to have a function of recording an image captured in response to the establishment of a specific condition that can be established at a low frequency in a predetermined recording area. More preferably, the function may be such that an image captured when a specific condition that can be satisfied at a frequency lower than the maximum settable acceleration is satisfied is recorded in a predetermined recording area.

  Further, each embodiment and each modification described above is an exemplification, and it goes without saying that partial replacement or combination of the configurations shown in each embodiment and each modification is possible, and each embodiment and each modification are also possible. The components described in the modification may be arbitrarily combined. For example, the controller 130 may perform processing in any one of the first embodiment and the first to fifth modifications of the first embodiment, and the second and second modifications of the first and second embodiments. Any one of these processes may be executed in parallel (for example, by multitasking). For example, the controller 130 performs an event recording process (FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8) when a plurality of conditions are met and an event recording process (FIG. 9, 10, 11, and 12) may be executed by multitasking. In this case, event recording processing when a plurality of conditions are satisfied (step S109, step S119, step S129, step S139, step S149, step S159), or event recording processing when a single condition is satisfied (step S205, In step S215, step S225, and step S235), information such as the location and time of occurrence of the accident may be labeled and recorded on the image data.

  The event type may be recorded in association with the image data. The type of event may be information specifying the content of the condition step for performing the step of the event recording process of each drawing (step Sxx9 (xx is a numerical value described in each drawing, the same applies hereinafter)). For example, it may be information (for example, the name of the condition) that specifies the conditions of step Sxx3 in each figure, step Sxx5 in FIGS. 3 to 8, and step Sxx7. For example, in the case of FIG. 3, information for specifying the conditions of S103, Step S105, and Step S107, which are the conditions for performing Step S109 of the event recording process, may be recorded. It is preferable to record the information “within a predetermined time” and “detect that the user has performed a specific action” in association with the image data. The same applies to the flows in other figures.

  Note that when multiple conditions are satisfied, for example, if only a single condition is satisfied, the event recording process is performed less frequently than when the event recording process is performed when acceleration of a predetermined value or more occurs. Even if it is not possible to do so, it is assumed that a condition that makes it possible to reduce the frequency of event recording processing compared to the prior art is satisfied by setting a plurality of conditions as event recording processing conditions, etc. Good. Further, when the above single condition is satisfied is, for example, a single condition different from the generation of acceleration of a predetermined value or more, compared to the conventional case where event recording processing is performed when acceleration of a predetermined value or more occurs. Thus, it is preferable that a condition that makes it possible to reduce the frequency of performing the event recording process is satisfied. Similarly, the controller 130 performs processing in any one of the first embodiment and the first to fifth modifications of the first embodiment and the third embodiment or the third embodiment. The processing may be performed in multitasking. To describe this in detail, the controller 130 detects event recording processing when a plurality of conditions are satisfied (step S109, step S119, step S129, step S139, step S149, step S159), and other abnormal situations such as accidents. A process (step S307, step S317) for transmitting information to an external server when there is a possibility that it has occurred in a vehicle (a vehicle different from the vehicle on which the system is mounted) or the like is executed by multitasking. It is also good. In this case, in the event recording process (step S109, step S119, step S129, step S139, step S149, step S159) when a plurality of conditions are satisfied, information such as the location and time of occurrence of the accident is labeled on the image data. In the process of recording or transmitting information to an external server (steps S307 and S317), information such as the location and time of occurrence of the accident may be labeled and transmitted to the image data. Furthermore, similarly, the process of any one of the second embodiment and the first to third modifications of the second embodiment and the process of the third embodiment or the third embodiment are modified. The process may be performed by a task, or the process of any one of the first embodiment and the first to fifth modifications and the second embodiment and the modification of the second embodiment Any one of the processes 1 to 3 and the process of the third embodiment or the modified example of the third embodiment may be executed by multitasking.

  Moreover, you may further apply the invention and each component which are described in the means to solve a subject to the combination of each component of each Example and each modification. About the same effect by the same composition of a plurality of examples and a plurality of modifications, it does not refer to every example and modification sequentially. Furthermore, the invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.
