Description

  The present disclosure relates to a technique for recording driving of a vehicle, and more particularly to a technique for supporting safe driving.

  In recent years, car insurance has been determined that the driver's safe driving characteristics are judged (scored), and if it is judged that safe driving is performed, the driver is recognized as a driver with a low accident risk and the insurance premium is discounted. Has been commercialized.

  As such car insurance, for example, if there is a correlation between “the occurrence of sudden start / brake of a car” and “accident risk”, “the occurrence of acceleration / deceleration” (hereinafter referred to as “driving characteristics”). There is car insurance that is reflected in insurance premiums. Specifically, a safe driving determination device is installed in a vehicle contracted with the car insurance. The safe driving determination device measures driving characteristics and scores accident risk. When the driver who is the subject of the car insurance performs safe driving with few sudden starts and sudden braking, the insurance premium is discounted according to the score calculated by the safe driving determination device. The safe driving determination device currently used for automobile insurance is fixed to a contracted vehicle with Velcro (registered trademark) and used. However, no special measures are taken regarding the identification of the person, automobile, and travel to be judged.

  Regarding automobile insurance, for example, Japanese Patent Laid-Open No. 2002-259708 (Patent Document 1) states that “automobile insurance considering whether parts such as tires and brake pads for safely driving an automobile are maintained and managed. "Vehicle insurance premium calculation system" for calculating "charge" is disclosed (paragraphs [0004] [0005]).

  The system includes an in-vehicle device having a use state detection unit for detecting a use state of a vehicle, a data input unit related to vehicle maintenance or management, and an insurance for calculating a vehicle insurance premium based on a detection result and input data. And a server having a charge calculation means. The in-vehicle device includes an operation state detection unit and a mounting state detection unit. The operation state detection means includes various sensors, such as the degree of accelerator depression, travel speed, time, engine speed change, transmission settings (parking, reverse, drive, neutral, etc.), right / left turn signal usage, The headlamp lighting status or the like is detected, and the detection result is output as data. The wearing state detecting means detects the wearing state of the seat belt, the wearing state of the child seat, the use position of the headless trait, and the like, and outputs the detection result as data. The system calculates automobile insurance premiums using these operation state detection data, wearing state detection data, and vehicle maintenance management data.

JP 2002-259708 A

  According to the technique disclosed in Japanese Patent Application Laid-Open No. 2002-259708, there is a possibility that data may be illegally operated when the driving recording device mounted on the vehicle is removed, and the automobile insurance premium may not be calculated correctly. There is sex. Therefore, there is a need for a technique that prevents unauthorized manipulation of data.

  The present disclosure has been made to solve the above-described problems, and an object in one aspect is to provide an operation recording device that generates data for determining operation characteristics. An object in another aspect is to provide a system for determining driving characteristics. Still another object of the present invention is to provide a method in which an apparatus mounted on a vehicle generates data for determining driving characteristics.

  According to one embodiment, an operation recording device is provided that generates data for determining operation characteristics. This driving recording device includes an authentication unit for confirming whether or not the driver of the vehicle is registered as a valid user of the driving recording device, and attachment / detachment detection for detecting the attachment / detachment state of the driving recording device in the vehicle. And when the vehicle travels on a public road when the driver is a legitimate user and the driving recording device is mounted on the vehicle. And an output unit for outputting data obtained by traveling of the vehicle as data certifying traveling by the driver.

  In one aspect, when the vehicle is unfairly removed from the vehicle, the traveling record is not accumulated, so that the determination accuracy of safe driving can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  With reference to FIG. 1, the technical idea which concerns on this Embodiment is demonstrated. FIG. 1 is a diagram illustrating an example of authentication performed when a vehicle is driven. The authentication procedure according to the present embodiment is performed by the mobile device 10, the operation recording device 100, and the server 120. The driving recording apparatus 100 records the running state of the vehicle in the vehicle on which it is mounted. For example, the running state may include timing, degree of acceleration, accelerator, brake and the like. The driving state is transmitted from the driving recording device 100 to the server 120 that can analyze driving characteristics. Therefore, the driving recording device 100 can also function as a device for determining the degree of safe driving of the driver.

  In one aspect, the mobile device 10 is held by a vehicle driver. The mobile device 10 is, for example, a mobile phone, a smart phone, or other portable information communication terminal, and at least holds information about a user of the mobile device 10 and can communicate the information with other information communication devices. That's fine.

  The mobile device 10 includes, for example, a processor, a memory, a touch panel, a camera, and a communication interface. The portable device 10 can hold an application program for using the operation recording device 100. The application is stored in the mobile device 10 by downloading via the Internet or by receiving from the operation recording device 100 by the provider of the operation recording device 100. The application program enables the mobile device 10 to communicate with the operation recording device 100. Further, the application program manages information on the driver as a valid user of the driving recording apparatus 100. The managed information may include information for identifying the driver, such as the driver's image, name, and other information.

  The driving recording device 100 is installed in a vehicle. The driving recording device 100 is provided free of charge or for a fee, for example, from a company that provides automobile insurance. The operation recording apparatus 100 includes a CPU, a memory, a communication interface, and a power supply unit. The power supply unit can include at least either a battery or an adapter that receives power supply from the outside.

  The server 120 is realized by a computer having a known configuration. The server 120 is managed by a car insurance provider or an operator that provides an authentication service according to the present embodiment.

(Driver authentication)
The mobile device 10 performs driver authentication. Specifically, the mobile device 10 authenticates whether the driver of the vehicle is a valid user who uses the driving recording device 100. For example, the mobile device 10 stores information acquired from the user of the mobile device 10 (the user's face image, voiceprint, voice, password input by the user, etc.) and the mobile device 10 in advance. Whether or not the driver is a valid user is confirmed based on whether or not the same information matches.

(Body certification)
The driving recording device 100 is fixed to the vehicle by, for example, a hook-and-loop fastener, an adhesive sheet, a bolt, a magnet, or the like. The driving recording apparatus 100 includes a mechanism that detects whether or not the state of being fixed to a predetermined vehicle continues. For example, in one aspect, driving recording device 100 includes an acceleration sensor.

(Run certification)
Furthermore, the driving recording apparatus 100 checks whether or not the vehicle has traveled. For example, if the insurance premium of a car is determined depending on the incidence of accidents at a mileage, it can be pretending that the vehicle has traveled more than the actual mileage. For example, it is also conceivable that the operation recording device 100 is detached from the vehicle and attached to a travelable railway model. In such a case, the driving recording apparatus 100 determines that the vehicle is not actually driving the action even if the driving state (for example, detection of periodic vibration) is detected.

  The driving recording apparatus 100 further generates data 130 including results of driver authentication, vehicle body authentication, and travel authentication. The operation recording apparatus 100 establishes communication with the server 120 and transmits data 130 to the server 120.

  The driver authentication will be further described with reference to FIG. FIG. 2 is a diagram illustrating a state in which the driving recording apparatus 100 is mounted on the vehicle and the driver is on the vehicle.

  When the driver gets on, the driving recording device 100 and the portable device 10 perform near field communication and establish mutual communication. The driver gives the operation recording apparatus 100 an operation for authenticating the driver himself. For example, the driver performs an operation for taking a self-portrait, an operation for scanning a fingerprint, an input of a password, and the like on the driving recording apparatus 100. The driving recording apparatus 100 transmits the image data, the voiceprint feature amount, the password, and the like acquired by such an operation to the mobile device 10. The portable device 10 temporarily holds data sent from the operation recording device 100.

[Wireless communication range]
With reference to FIG. 3, a wireless communication range in the authentication system according to the present embodiment will be described. FIG. 3 is a diagram illustrating a wireless communication range 300 between the operation recording device 100 and the portable device 10.

  As shown in state A, when the operation recording device 100 and the portable device 10 exist in the wireless communication range 300, the operation recording device 100 and the portable device 10 can communicate with each other. The wireless communication range 300 may be, for example, a radius of about several meters, and may be at least as long as a vehicle on which the driving recording device 100 is mounted is included.

  As shown in state B, when the mobile device 10 is outside the wireless communication range 300, the mobile device 10 and the operation recording device 100 cannot communicate. For example, the state B corresponds to the case where the driver having the mobile device 10 gets out of the vehicle.

[Configuration of Operation Recording Device 100]
With reference to FIG. 4, the configuration of the operation recording apparatus 100 will be described. FIG. 4 is a block diagram illustrating functions realized by the operation recording apparatus 100. The operation recording apparatus 100 includes an operation state detection unit 101, an attachment state detection unit 102, an attachment state data storage unit 103, a removal determination unit 104, a display unit 105, a voice output unit 106, and a safe driving determination unit 107. And a clock unit 108, a control unit 109, and a battery 110.

  The operation state detection unit 101 detects an input to the start of the operation recording apparatus 100 and a reset button (not shown).

  The attachment state detection unit 102 detects gravity data by a triaxial acceleration sensor or the like measured when the driving recording device 100 is attached to the automobile.

  The attachment state data storage unit 103 stores the gravity data detected when the operation recording apparatus 100 is first attached to the vehicle, and the date and time at that time. The attachment state data storage unit 103 is realized by, for example, a built-in or detachable nonvolatile memory.

  The removal determination unit 104 determines whether or not the operation recording device 100 has been removed from the vehicle by comparing the gravity data stored in the attachment state data storage unit 103 with the gravity data detected at the present time. The removal determination unit 104 is realized by a circuit element configured to realize the determination process, or a program module and a CPU that realize the process.

  The display unit 105 displays cumulative count data and the like for a certain period for an event determined to be dangerous driving behavior according to the score of the safe driving characteristic. The display unit 105 is realized by, for example, an LED (Light Emitting Diode) or a liquid crystal panel.

  The audio output unit 106 informs the driver of dangerous driving behavior or informs the driver that the battery has run out. The audio output unit 106 is realized, for example, as an interface for transmitting a signal for outputting audio to the built-in speaker or the mobile device 10 or other external device.

  The safe driving determination unit 107 calculates the degree of safe driving. The time measuring unit 108 measures the time in the operation recording device 100. For example, the safe driving determination unit 107 quantifies the driving situation of the vehicle using data acquired from various sensors and time information obtained by the time measuring unit 108. As an example, the safe driving determination unit 107 quantifies the driving situation by adding a value obtained by multiplying each data and a weighting coefficient associated in advance according to the value of the data. When the numerical value exceeds a reference value defined in advance as a guide for safe driving, the safe driving determination unit 107 determines that the driving is safe driving.

  The control unit 109 controls the operation and stop of the operation recording device 100. More specifically, the control unit 109 controls the operation of each mechanism described above. In another aspect, the control unit 109 can control the retained data when it is detected that the operation recording apparatus 100 is removed from the vehicle. For example, when the driving recording device 100 is removed from the vehicle after the driving recording device 100 has received a signal indicating removal from the portable device 10, the control unit 109 has data indicating that the removal is a valid removal. Is stored in the attachment state data storage unit 103. On the other hand, when the operation recording device 100 is removed from the vehicle without receiving the signal from the portable device 10, the control unit 109 displays data indicating that the removal is an unauthorized removal as an attachment state data storage unit. Save to 103. Alternatively, in yet another aspect, the control unit 109 may erase the data stored in the attachment state data storage unit 103 according to the setting in the operation recording device 100.

  The battery 110 supplies power to the operation recording device 100. For example, the battery 110 is a rechargeable battery such as a dry battery, a rechargeable battery, or a button battery. In another aspect, the battery 110 may be configured to receive power from another device (for example, a mobile battery or a personal computer) via a communication cable using a PoE (Power over Ethernet (registered trademark)) function. .

  The operation of the operation recording apparatus 100 will be described with reference to FIG. FIG. 5 is a diagram illustrating the transition of the state of the operation recording apparatus 100. State A to state C represent states when the operation recording device 100 is normally attached to the vehicle. State D to state F represent states when the operation recording device 100 that has been normally attached is removed from the vehicle.

[No removal]
Referring to state A in FIG. 5, driving recording device 100 is attached to the vehicle. The driving recording apparatus 100 includes, for example, a triaxial acceleration sensor. In the operation recording apparatus 100, when a switch (not shown) is set to ON, gravity data is output from the triaxial acceleration sensor. The operation recording apparatus 100 stores the output value (for example, X axis: Y axis: Z axis = numerical value a: numerical value b: numerical value c) in the attachment state data storage unit 103.

  Thereafter, when the driver starts traveling of the automobile, the operation recording device 100 starts to operate. For example, as shown in the state B, the operation recording apparatus 100 periodically installs information on the state of the vehicle (for example, speed), gravity data from the triaxial acceleration sensor, and time information from the time measuring unit 108, as attachment state data. It is stored in the storage unit 103.

  The driving recording device 100 uses each data stored in the attachment state data storage unit 103 as a driver's driving behavior, such as sudden acceleration, sudden braking, the number of sudden steering, traveling speed, rest interval, traveling time zone. Create numerical data indicating (eg, daytime, midnight, etc.). The driving recording apparatus 100 further accumulates the created numerical data and digitizes the driving characteristics of the driver. For example, the driving recording device 100 compares the accumulated data with standard data previously stored in the driving recording device 100 as the safe driving determination unit 107, and driving by the driver belongs to safe driving. Judge whether or not

  The operation recording apparatus 100 outputs the result of the determination through the display unit 105 or the audio output unit 106. For example, when the driver's driving belongs to safe driving, the display unit 105 lights a green indicator. Or the audio | voice output part 106 outputs the message or sound for notifying that. When the driving does not belong to safe driving, the display unit 105 lights a red indicator. Or the audio | voice output part 106 outputs the warning message or warning sound for notifying that, and prompts the driver | operator to drive safely.

  In this way, the driving recording device 100 determines the driver's safe driving characteristics as the safe driving determination unit 107 and scores it. The driving recording apparatus 100 displays the result of the determination on the display unit 105 as, for example, a score or other index, or notifies the sound that the driving of the driver is close to dangerous driving by the voice output unit 106. Thus, the driving state is fed back to the driver. Such feedback allows the driver to change his driving style once he knows that his driving is dangerous. For example, the driver can suppress sudden acceleration and sudden steering. As a result, the occurrence of an accident can be suppressed.

  When the driver continues driving with the operation recording apparatus 100 attached, as shown in the states A, B, and C, the detection result of the gravity data becomes a constant level.

  The driving recording device 100 detects gravity data in a certain period during the period of continuous measurement of the safe driving characteristics. Note that, in a certain aspect, the measured gravity data can be valid only when the vehicle is stopped (when the three-axis acceleration data is constant for a short period of time). The removal determination unit 104 detects gravity data (X axis: Y axis: Z axis = numerical value a: numeric value b: numeric value c) detected during the stop and gravity data (X Axis: Y axis: Z axis = Numerical value a: Numerical value b: Numerical value c) are compared. If these numerical values match within a predetermined error range, the removal determination unit 104 determines that “no removal” (that is, the operation recording device 100 has not been removed from the vehicle), and is safe. Continue judging driving behavior (scoring).

[With removal]
Next, the movement at the time of abnormality by removal will be described. As shown in state D of FIG. 5, first, the driving recording device 100 detects gravity data with a built-in three-axis acceleration sensor when it is first attached to a parked vehicle (for example, X axis: Y axis: Z). Axis = numerical value a: numerical value b: numerical value c). The attachment state data storage unit 103 stores the detected gravity data. Thereafter, when the driver starts driving the vehicle, the driving recording device 100 starts to operate and collects data related to the driving behavior of the driver. The process up to this point is the same as in the state A. The operation recording apparatus 100 detects gravity data for a certain period.

  As shown in state E, the operation recording device 100 may be subsequently removed from the automobile. For example, it is conceivable that the driver removes the driving recording device 100 once attached to the automobile in order to intentionally change the score that is the safe driving determination result. The operation recording device 100 is removed, for example, to tamper with data held in the operation recording device 100 to delete disadvantageous data or to rewrite data so as to lead to an advantageous determination result. .

  The operation recording device 100 detects gravity data ((X axis: Y axis: Z axis = numerical value d: numeric value e: numeric value f) detected after being removed from the vehicle and gravity stored in the attachment state data storage unit 103. Data (X axis: Y axis: Z axis = Numerical value a: Numerical value b: Numerical value c) Since these gravity data do not match (a ≠ d, b ≠ e, c ≠ f), the removal determination unit 104 determines that “removed” (the driving recording apparatus 100 has been removed from the vehicle), and the control unit 109 immediately stops measuring driving behavior characteristics in response to the result of the determination.

  As shown in state F, after the score of the result used for the determination of safe driving has been altered, the driver reattaches the driving recording apparatus 100 to the automobile. However, once it is determined that “removed”, the operation recording device 100 does not start measurement again unless a reset button (not shown) is pressed. In a certain aspect, when the reset button is pressed, the data accumulated in the attachment state data storage unit 103 is deleted. Therefore, there is no data necessary for the judgment of safe driving, and the merit (for example, reduction of insurance premium) by safe driving cannot be received. In this way, unauthorized use by the user (= driver) of the operation recording apparatus 100 can be prevented.

  The control structure of the operation recording apparatus 100 will be described with reference to FIG. FIG. 6 is a flowchart showing a part of processing executed by the operation recording apparatus 100.

  In step S610, the operation recording apparatus 100 detects that it is attached to the automobile. For example, when the driver presses a start switch (not shown) after attaching the driving recording device 100 to the automobile, the driving recording device 100 determines that the driving recording device 100 is attached to the automobile, and performs an initial operation (memory initialization, etc.). ).

  In step S620, the operation recording apparatus 100 detects gravity data using a triaxial acceleration sensor, and detects gravity data detected in the attachment state data storage unit 103 (eg, X axis: Y axis: Z axis = a: b: c) is stored. In one aspect, the operation recording apparatus 100 associates the gravity data with a time stamp indicating the date and time when the gravity data is detected.

  In step S630, the driving recording apparatus 100 detects that the vehicle has started running. In response to the detection, the operation recording apparatus 100 starts counting by a timer for collecting data. Furthermore, the driving recording apparatus 100 starts measuring safe driving characteristics.

  In step S640, operation recording apparatus 100 determines whether or not the vehicle has stopped and the time measured by the timer has passed a predetermined time. For example, this determination is made when the vehicle speed becomes zero. If operation recording apparatus 100 determines that the measurement time has elapsed after the vehicle has stopped (YES in step S640), it switches control to step S650. If not (NO in step S640), operation recording apparatus 100 returns control to step S630.

  In step S650, operation recording apparatus 100 detects gravity data using a triaxial acceleration sensor, and stores the detected gravity data in attachment state data storage unit 103. In one aspect, the operation recording apparatus 100 associates the gravity data with a time stamp indicating the date and time when the gravity data is detected.

  In step S660, the operation recording apparatus 100 compares the gravity data acquired in step S620 with the gravity data acquired in step S650. If operation recording apparatus 100 determines that these gravity data match (YES in step S660), control is switched to step S630 and measurement is continued (step S630). If not (NO in step S660), operation recording apparatus 100 switches control to step S670.

  In step S670, the operation recording apparatus 100 determines that the operation recording apparatus 100 has been removed from the vehicle (removed). Based on the determination, the driving recording device 100 stops the subsequent safe driving characteristic measurement.

  As described above, according to the driving recording apparatus 100 according to the present disclosure, the driver or the like removes the driving recording apparatus 100 from the automobile and performs tampering such that the safe driving determination score that is intentionally measured is illegally operated. Can be suppressed. As a result, the operation recording apparatus 100 can output an accurate and reliable safe driving determination result. When an accurate and reliable determination result is obtained, for example, it is possible to accurately determine the safe driving technique for each individual when renewing the officially authorized driving license. In addition, it is possible to use an automobile insurance premium discount for individuals determined to be safe driving.

[Position detection]
Another aspect will be described with reference to FIG. FIG. 7 is a block diagram illustrating a configuration of an operation recording apparatus 700 having a function of detecting position information. As illustrated in FIG. 7, the operation recording apparatus 700 further includes a position information detection unit 111 in addition to the configuration illustrated in FIG. 4.

  The position information detection unit 111 detects position information of the operation recording device 700. The detection of the position information is realized by, for example, a GPS (Global Positioning System) or other satellite positioning function or by using position information detected by a portable terminal held by the driver.

  With reference to FIG. 8, the case where position information is used for determination of removal will be further described. FIG. 8 is a diagram illustrating determination using position information and gravity data.

  In one aspect, the driving recording device 700 detects gravity data with a built-in triaxial acceleration sensor during parking and stopping. At the same time, the operation recording apparatus 700 also saves the position information output from the position information detection unit 111 with a built-in GPS or the like in the attachment state data storage unit 103 (eg, position coordinates: X axis: Y axis: Z axis). = (Latitude p, Longitude q): Numerical value a: Numerical value b: Numerical value c). The attachment state data storage unit 103 can store a plurality of data of position coordinates that are frequently parked and stopped.

  Thereafter, when the driver starts driving the vehicle, the driving recording device 700 starts operation, collects information on the driving behavior of the driver, and stores it in the attachment state data storage unit 103. The collected data includes, for example, data output from various built-in sensors, time information obtained from the time measuring unit 108, and the like. The driving recording device 700 creates data such as sudden acceleration, sudden braking, the number of sudden handles, traveling speed, rest interval, traveling time zone (daytime or midnight?) From these data. The safe driving determination unit 107 analyzes the characteristics of the driver's safe driving using the created data, and scores the analysis result. The attachment state detection unit 102 detects gravity data and position information in a certain period during which the safe driving characteristics are continuously measured.

  When the result detected by the attachment state detection unit 102 matches the position coordinates stored in the attachment state data storage unit 103, the removal determination unit 104 is stored in the attachment state data storage unit 103. It is determined whether or not the gravity data (position coordinates: X axis: Y axis: Z axis = (latitude p, longitude q): numerical value a: numerical value b: numerical value c) matches the detected gravity data.

  As shown in Case A, when these values match, the operation recording device 700 determines that “no removal” and continues to measure the safe driving characteristics. Further, as shown in case B, when the respective values do not match (position coordinates: X axis: Y axis: Z axis = (latitude p, longitude q): numerical value d: numerical value e: numerical value f), it is removed. The determination unit 104 determines “with removal” and immediately stops the measurement of the safe driving behavior characteristic.

  In the case of the configuration shown in FIG. 3, for example, when a driver parks a car on a steep slope, the gravity data acquired by the 3-axis acceleration sensor at that time is larger than the gravity data acquired at the time of installation. On the other hand, as a result, there is a possibility that an erroneous detection is made that the vehicle has been removed even though the vehicle specified in the contract is correctly equipped with the driving recording device.

  On the other hand, since the driving recording apparatus 700 shown in FIG. 7 can further store the position information, the position information can be used in addition to the gravity data for the determination of the safe driving action. As a result, the accuracy of determination of the presence or absence of safe driving behavior by the driving recording device 700 can be improved. Further, since the position information is also used for the determination, tampering is prevented, and it is possible to perform a reliable determination of driving behavior that is not deceptive. For example, by incorporating a GPS chip or the like in the position information detection unit 111 in the driving recording device, the driving recording device 700 may have the same position information of the driving recording device at the timing to be compared. Regardless, if gravity data is different, it is determined that there is a removal. Further, the driving recording device 700 can determine that there is removal even when the positional information does not match by comparing the positional information of the driving recording device with the positional information of the contract vehicle.

[Image processing]
With reference to FIG. 9, an operation recording apparatus 900 according to another aspect will be described. FIG. 9 is a block diagram illustrating the configuration of the operation recording apparatus 900. The operation recording apparatus 900 has an image detection unit 122, an image data storage unit 123, an image non-display unit instead of the attachment state detection unit 102, the attachment state data storage unit 103, and the removal determination unit 104 in the configuration shown in FIG. A determination unit 124 is provided.

  The image detection unit 122 images the surrounding environment of the automobile on which the driving recording device 900 is mounted. The image detection unit 122 is realized by, for example, a camera. The image data storage unit 123 stores an initial image photographed when the image data storage unit 123 is attached to a car in a parking lot at the driver's home. The image non-determination unit 124 determines whether or not the initial image data stored in the image data storage unit 123 matches the currently captured peripheral image data.

  The operation of the operation recording apparatus 900 will be described with reference to FIG. FIG. 10 is a diagram illustrating a state at the time when the operation recording apparatus 900 is appropriately attached to the vehicle and a subsequent state.

  As shown in case A, the driving recording device 900 captures an image of the front of the vehicle when it is first attached to the vehicle, and acquires an image 1010. For example, when the driving recording apparatus 900 attaches the driving recording apparatus 900 to the vehicle in a garage at the driver's home and presses a switch (not shown), the driving recording apparatus 900 starts an initial operation, and the front of the image detection unit 122. Is captured and an image 1010 is obtained. When the driver returns to the garage after driving the vehicle and turns off the engine, the driving recording apparatus 900 captures the front of the image detection unit 122 again and acquires an image 1020. In this case, the image 1010 and the image 1020 are substantially the same. “Substantially the same” means that, for example, a significant difference does not occur in the feature amount acquired by image processing. When the image 1010 and the image 1020 coincide with each other, the vehicle is parked at the same place, and therefore it can be estimated that the driving recording device 900 is used in a state where it is mounted on the vehicle.

  On the other hand, the operation recording device 900 may be detached from the vehicle to which it is first attached and attached to another vehicle. In this case, the driver of another vehicle may be a resident of another house. Therefore, the driving recording device 900 compares the image 1030 acquired when the driving recording device 900 is first attached to the vehicle with the image 1040 acquired when the vehicle stops thereafter. In this case, there is a high possibility that the appearance of the residence of the driver of the first vehicle and the residence of the driver of the other vehicle are different. Therefore, in this case, the feature amount of the image 1030 and the feature amount of the image 1040 are different. Therefore, when the image 1030 and the image 1040 do not match, the driving recording device 900 may stop the safe driving determination that the driving recording device 900 may be removed from the vehicle.

  The image non-determination unit 124 determines whether or not the initial surrounding environment image (for example, the image 1010 or the image 1030 of the home parking lot) and the current image 1020 or the image 1040 match. Can be considered. For example, by detecting several singular points (window corners, signboard and roof shapes, white lines on the ground, telephone poles, etc.) from each image and comparing the data of the singular points, the images match. It can be determined whether or not.

[Run certification]
Next, travel authentication according to the present embodiment will be described with reference to FIG. FIG. 11 is a diagram illustrating an outline of travel authentication.

(Run authentication by image recognition of surrounding environment)
In one aspect, the driving recording device 100 determines whether or not the vehicle in which the driver is actually registered (that is, the vehicle on which the driving recording device 100 is mounted) is traveling on a public road, It can be specified by detecting signs, road white lines, and the like. The driving recording apparatus 100 transmits an image photographed at least intermittently instead of constantly by a built-in or connected camera to the server 120 in the cloud as traveling evidence. The server 120 is realized as a computer device having a known configuration having an image processing function and an image recognition function.

  Or, when the driving recording device 100 transmits the image as it is, there is a concern about an increase in the network traffic, the driving recording device 100 displays characteristic information extracted from the image (for example, data indicating the presence or absence of a forward vehicle). Alternatively, text data having a small amount of information such as data indicating the presence or absence of a traffic light may be transmitted to the server 120 instead of the image data itself.

  For example, the state A represents an image when a vehicle on which the driving recording device 100 is mounted is traveling behind another vehicle. In this case, for example, the image is sent from the operation recording device 100 to the server 120 that can communicate with the operation recording device 100 via the Internet. The server 120 has an image processing function and an image recognition function.

  When the server 120 recognizes another vehicle 1110 from the image received from the driving recording device 100, it can be determined that the vehicle equipped with the driving recording device 100 is traveling on a public road. This determination is realized, for example, by a server 120 that has an image processing function and can communicate with the operation recording apparatus 100. The server 120 can be accessed by the operation recording device 100 via the Internet.

  State B is a diagram illustrating a state in which the vehicle on which the driving recording apparatus 100 is mounted is waiting for a signal at an intersection. The driving recording apparatus 100 captures a landscape in front of the vehicle and transmits an image obtained by the capturing to the server 120. For example, the server 120 recognizes the vehicle 1120 and the signal 1130 from the image. When the other vehicle 1120 and the signal 1130 that may exist in the action are recognized, the server 120 can determine that the vehicle on which the driving recording device 100 is mounted is traveling on a public road.

  In addition, the surrounding environment used for driving | running | working authentication is not restricted to a driving vehicle ahead, the oncoming vehicle in stop, or a traffic signal as shown in FIG. For example, the travel authentication can be performed by an image of a roadside or a road sign, a traveling oncoming vehicle, or the like.

(Driving authentication based on location name detection)
The travel authentication using the place name will be described with reference to FIGS. FIG. 12 is a flowchart showing a part of processing performed in the travel authentication using the place name. FIG. 13 is a diagram for explaining travel authentication using place names.

  Referring to FIG. 12, in step S <b> 1210, CPU of server 120 extracts the place name of the intersection from the image sent from operation recording apparatus 100. For example, the operation recording device 100 transmits an image from a camera to the server 120. The CPU recognizes the place name display board at the intersection from the received image. The CPU extracts the intersection character from the recognized place name display board.

  In step S1220, the CPU converts the place name into position information. This conversion is performed based on, for example, a map representing the correspondence between place names and position information. The map is stored in the server 120 in advance. The map is based on, for example, an electronic national land basic map by the Ministry of Land, Infrastructure, Transport and Tourism. The CPU refers to the signal intersection database from the electronic national land basic map and converts the place name of the intersection into the intersection number or position information (latitude and longitude).

  In step S1230, operation recording apparatus 100 identifies a position on the map from the position information. For example, the CPU refers to the latitude and longitude of the intersection and specifies the position on the map stored in the server 120. When this position is specified, the CPU can determine that the vehicle is traveling on a public road.

  Referring to FIG. 13, in a certain situation, a vehicle equipped with driving recording device 100 stops at intersection “Tokyo Skytree East”. In response to the stop, the camera built in the driving recording apparatus 100 photographs the front. An image obtained by shooting is transmitted from the operation recording apparatus 100 to the server 120. The timing for transmission may be either during stopping of the vehicle or during traveling. Further, the transmission of the image data may be performed based on an instruction from the driver of the vehicle.

  When the server 120 receives the image data from the driving recording apparatus 100, the CPU of the server 120 executes character recognition processing, and the image 1310 representing the intersection sign is referred to as “Tokyo Skytree East” or “Tokyo Skytree E.”. Extract a string.

  The CPU further accesses the database 1320 using the extracted character string as a search key. The database 1320 may be either inside or outside the server 120. The CPU acquires latitude and longitude as a search result for the character string. The CPU plots the acquired latitude and longitude on the map 1330 and specifies the position. If the position exists on the road of the map 1330, the driving recording apparatus 100 determines that the vehicle has actually traveled on the public road.

  Thus, by detecting the place name display board on the road, it is possible to simultaneously acquire the position information together with the travel authentication. Therefore, for example, even in locations where radio waves from GPS satellites cannot be received (for example, in valleys and mountainous areas of tunnel buildings in urban areas), the data used for travel authentication should be used as data that complements location information. Is also possible.

[Three elements of safe driving]
With reference to FIG. 14 and FIG. 15, the element of the safe driving | operation of a motor vehicle is demonstrated. FIG. 14 is a diagram illustrating the relationship between the three elements of safe driving. The three elements include a driver, a vehicle, and a road environment. For example, in order to determine the safe driving degree of a driver, an “acceleration sensor or the like” is measured, and the driving skill of the driver is quantified. For a vehicle, the value of safe driving of the vehicle is determined by the presence or absence of a function or equipment that ensures safe driving or the level of collision safety performance.

  The road environment will be described with reference to FIG. FIG. 15 is a diagram for explaining a difference in road environment, which is one of the elements of safe driving.

  In one aspect, as shown in Case A, in the case of road environment 1510, the vehicle can perform safe driving when there are no other traveling vehicles or pedestrians. On the other hand, as shown in Case B, in the case of the road environment 1520, since there are many pedestrians, the vehicle needs to travel at a reduced speed, and there is a high possibility that an accident with the pedestrian will occur. Accordingly, the traffic accident occurrence risk in the road environment 1520 is higher than the traffic accident occurrence risk in the road environment 1510.

  An application example of the technical idea according to the present disclosure will be described with reference to FIG. FIG. 16 is a diagram for explaining a case where a driver's personal history is applied to the calculation of insurance premiums for automobile accident insurance. In one aspect, the server 120 holds an individual driving travel history 1610 and a traffic accident occurrence history 1620. For example, the individual driving travel history 1610 includes the traveling history of each driver (for example, Mr. A, Mr. B, etc.). The travel history includes the time when the stop position of the vehicle on which the driving recording device 100 is mounted is detected, and the position. The travel history is transmitted from each operation recording device 100 to the server 120.

  The CPU of the server 120 calculates the risk of accident occurrence using the travel history and the traffic accident occurrence history 1620 in the work area. For example, accident risk is preset for each area. Each area is defined by subdividing the map. For example, each area is associated with a latitude and longitude that is the center of the range. Alternatively, the name of the area may be defined for each travel route (for each road). The accident occurrence risk is defined, for example, by a provider of automobile accident insurance service according to the degree of occurrence of a past traffic accident. In another aspect, the risk of occurrence of an accident may be defined by a public agency.

  In the example shown in FIG. 16, Mr. A's accident occurrence risk value is 2,186 points, and Mr. B's accident occurrence risk value is +86 points. Therefore, the accident occurrence risk of the route on which Mr. A's vehicle travels is higher than the accident occurrence risk on the route on which Mr. B's vehicle travels. Therefore, for vehicles traveling on routes with a high risk of accidents, the insurance premiums were increased so that the premiums for vehicles traveling on routes with a low risk of accidents were increased to meet the accident risk. A fair burden can be imposed on beneficiaries (drivers).

  Next, the configuration of the server 120 according to the present embodiment will be described with reference to FIG. FIG. 17 is a block diagram illustrating a hardware configuration of the server 120.

  The server 120 includes, as main components, a CPU (Central Processing Unit) 1 that executes a program, a mouse 2 and a keyboard 3 that receive input of instructions from a user of the server 120, data generated by execution of the program by the CPU 1, Alternatively, a RAM 4 that stores data input via the mouse 2 or the keyboard 3 in a volatile manner, a hard disk 5 that stores data in a nonvolatile manner, an optical disk drive device 6, a monitor 8, and a communication IF (Interface) 9 Is provided. Each component is connected to each other by a bus. A CD-ROM 9 and other optical disks are mounted on the optical disk drive 6. The communication IF 9 includes, but is not limited to, a USB (Universal Serial Bus) interface, a wired LAN (Local Area Network), a wireless LAN, and a Bluetooth (registered trademark) interface.

  The processing in the server 120 is realized by each hardware and software executed by the CPU 1. Such software may be stored in the hard disk 5 in advance. The software may be stored in a CD-ROM 9 or other non-volatile computer-readable data recording medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to the Internet or other networks. Such software is read from the data recording medium by the optical disk drive 6 or other data reading device, or downloaded via the communication IF 7 and then temporarily stored in the hard disk 5. The software is read from the hard disk 5 by the CPU 1 and stored in the RAM 4 in the form of an executable program. The CPU 1 executes the program.

  Each component which comprises the server 120 shown by FIG. 17 is a general thing. Therefore, it can be said that the most essential part according to the present embodiment is a program stored in the server 120. Since the operation of each hardware of server 120 is well known, detailed description will not be repeated.

  The data recording medium is not limited to a CD-ROM, FD (Flexible Disk), and hard disk, but is a magnetic tape, cassette tape, optical disk (MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital Versatile Disc)). ), IC (Integrated Circuit) card (including memory card), optical card, mask ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), flash ROM, etc. It may be a non-volatile data recording medium that carries a fixed program.
