  On the other hand, when an acceleration threshold is used to determine an accident, there is a possibility that an accident may be determined if the acceleration exceeds the threshold, even if the acceleration is not actually an accident. In addition, the acceleration transmitted from the vehicle may not be accurately received by the communication terminal. In addition, in order to increase the accuracy of accident determination, it is necessary to mount many sensors, and the system becomes complicated. Further, it is assumed that, for example, the driver must manually start the application to activate the accident detection means. In this case, since it takes time to start the application, the driver feels troublesome. For this reason, forgetting to start the accident detection means is induced.

<1-1. Hardware Configuration of Accident Judgment System 10>
A hardware configuration of the accident determination system 10 according to the embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a hardware configuration diagram of the accident determination system 10. As shown in FIG. 1, the accident determination system 10 includes a detection device 100 and a communication terminal 200 in a vehicle 500. For example, a beacon is used for the detection device 100. The communication terminal 200 is a portable communication terminal. For example, a smartphone is used for the communication terminal 200. The detection device 100 and the communication terminal 200 are connected by wireless communication 180 (Bluetooth (registered trademark) communication, Bluetooth Low Energy (registered trademark) communication (BLE communication), or Wi-fi (registered trademark) communication). The communication terminal 200 may be appropriately connected to the server 300 using a network 400 such as the Internet.

  The detection device 100 includes a measurement unit 110, a control unit 120, a storage unit 130, a communication unit 140, a power supply unit 150, an operation unit 160, and a display unit 170. The detection device 100 is fixedly installed on the vehicle 500. The detection device 100 may be small enough to fit in the driver's hand, thin, or light. For example, the weight of the sensing device 100 may be less than 18 grams, 50 millimeters in length, 37 millimeters in width, and about 13 millimeters in height. By having the above shape, the detection device 100 is retrofitted at an arbitrary position of the vehicle 500, such as near a center console, near a steering wheel, in a trunk, near a room lamp in a company, and the like. The detection device 100 may be installed by screwing, or may be installed using an adhesive. Further, the detection device 100 may be installed on a dashboard so as not to interfere with an airbag that is opened in the event of an accident.

  The measurement unit 110 has a function of measuring acceleration information (acceleration value) of the vehicle 500 using an acceleration sensor. The acceleration sensor may be a three-axis acceleration sensor or a six-axis acceleration sensor.

  The control unit 120 executes a program stored in the storage unit 130 such as a memory using a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or a RAM (Random Access Memory), so that a function corresponding to the program is performed. Is realized in the first communication terminal 100. Alternatively, the program may be obtained via a recording medium. Alternatively, the program may be received and acquired from the communication terminal 200. For example, when a beacon is used as the detection device 100, the firmware (program) is executed using the MPU.

  The storage unit 130 has a function of storing acceleration information.

  The communication unit 140 has a function of transmitting and receiving to and from the communication terminal 200. The communication unit 140 includes a transceiver for Bluetooth (registered trademark) communication, Bluetooth Low Energy (registered trademark) communication (BLE communication), or Wi-fi (registered trademark) communication.

The detection device 100 is driven using power from the power supply unit 150. For the power supply unit 150, for example, a button-type lithium ion battery is used. Note that the detection device 100 may specialize in acquiring and transmitting acceleration information. At this time, the amount of information processing of the detection device 100 is reduced. Thereby, the power consumption of the detection device 100 is also suppressed. The power consumption mode of the detection device 100 is changed according to the communication status.
For example, when the detection device 100 is a beacon and the communication terminal 200 is a smartphone, when the measuring unit 110 (acceleration sensor) detects the movement of the vehicle, the beacon is in a state of sending a signal for connecting to the smartphone (advertise this mode). Mode). Alternatively, the beacon is in a state where the beacon and the smartphone are connected, such as driving diagnosis and shock detection, and Bluetooth Low Energy (registered trademark) communication is performed (this mode can be called a drive mode).
Alternatively, the beacon enters a standby state in which the mode can shift to the drive mode in conjunction with the application of the smartphone (this mode can be referred to as a standby mode). Alternatively, the beacon stops functioning when the built-in acceleration sensor stops detecting movement (this mode can be called a sleep mode). As described above, since the power consumption can be reduced to the minimum according to the communication situation, it can be said that the detection device 100 is extremely excellent in power saving. For example, assuming that the detection device 100 performs driving for 120 minutes / day, it is possible to detect acceleration information and transmit acceleration information for about 500 days or more and for a running distance of about 20,000 km or more.

  The terminals on both sides (positive electrode side and negative electrode side) connected to the battery provided in the power supply section 150 have elasticity. For example, the terminals on both sides have a spring-like form. This prevents an instantaneous interruption of the power supply (for example, between the battery and the terminal) from occurring in the event of a collision. In addition, the power supply unit 150 may be screwed, adhered with an adhesive, or fitted so that an infant or the like does not accidentally swallow the battery.

  In addition, the operation unit 160 may be provided in the detection device 100 as appropriate. The operation unit 160 has a function of causing the detection device 100 to operate normally again when the detection device 100 does not function normally due to a failure or the like. For example, on the operation unit 160, a button larger than the fingertip is arranged so that the driver can easily press with one finger (for example, the index finger), and an orange frame is printed so that the button is conspicuous. Thus, the driver can easily operate the operation unit 160. Further, it is possible to prevent the operation unit 160 from being pressed by mistake.

  The display unit 170 uses LED indicators of a plurality of colors (for example, red and green). As a result, it is possible to obtain a luminance that can be easily recognized by the driver while having low power consumption.

  Communication terminal 200 includes a display unit 210, a control unit 220, a storage unit 230, an operation unit 240, and a communication unit 250.

  The display unit 210 is a display device such as a liquid crystal display or an organic EL display, and the display content is controlled by a signal input from the control unit 220. In the case of a display device (touch panel) having a touch sensor, the display unit 210 can exhibit the function of the operation unit 240.

  The control unit 220 executes a program stored in advance in the storage unit 230 such as a memory using the CPU and the RAM. Thereby, the function corresponding to the program is realized in the communication terminal 200. Further, the program may be obtained via a recording medium. By executing the program in the control unit 220, a user interface for realizing the accident determination service is provided to the display unit 210.

  The storage unit 230 has a function of storing the acceleration information received from the detection device 100.

  The communication unit 250 has a function of transmitting and receiving to and from the detection device 100 and the server 300. As the communication unit 250, a transceiver for performing Bluetooth (registered trademark) communication, Bluetooth Low Energy (registered trademark) communication (BLE communication), or Wi-fi (registered trademark) communication is used.

  The communication terminal 200 may further include a measuring unit 260. The measurement unit 260 may include a GPS (Global Positioning System), a gyro sensor, and an acceleration sensor. The information obtained by the measurement unit 260 may be used to supplement the information obtained by the communication unit 140 of the detection device 100.

  The server 300 includes a communication unit 310, a storage unit 320, and a control unit 330. The communication unit 310 has a function of performing information communication with the communication terminal 200 via the network 400. The storage unit 320 has a function as a database that stores the reported accident information by using the hard disk and the SSD. The control unit 330 has a function of performing accident information processing using a CPU and a RAM.

  The server 300 has a function of coping with the occurrence of an accident based on information transmitted from the communication terminal 200.

<1-2. System Configuration of Accident Judgment System 10>
FIG. 2 shows a processing flow in the accident determination system 10. Accident determination system 10, the processing the driver activates the accident determination system by riding in a vehicle 500, the driver performs the driving diagnosis while driving a car, the process of determining whether the accident, the accident happened When an accident occurs, an accident report is made and processing to assist the driver is executed. Each process will be described below.

(1-2-1. Accident judgment system activation process)
FIG. 3 shows a flow of the startup processing (S100) of the accident determination processing.
First, the detection device 100 starts driving (S101). A method of starting driving of the detection device 100 will be described below.

  First, a driver holding the communication terminal 200 gets on the vehicle 500. The detection device 100 detects the shaking of the vehicle 500 when the driver gets on the vehicle. By detecting this shaking, the detection device 100 starts driving. When the above driving method is used, the detection device 100 can be driven only when the vehicle is driven, so that power consumption can be suppressed. When the driver does not carry the communication terminal 200, it is confirmed that the connection cannot be established, and the operation enters the above-described standby mode. The standby mode is also set when the connection between the detection device 100 and the communication terminal 200 is released.

Next, the detection device 100 sends a detection notification to the communication terminal 200 (S103). Next, the communication terminal 200 that has received the detection notification starts activation of an application dedicated to the accident determination system 10 (which can be called an accident determination application) (S105). Subsequently, the communication terminal 200 on which the accident determination application has been started issues a connection request to the detection device 100 (S107). Next, when the connection between the detection device 100 and the communication terminal 200 is completed, the detection device 100 notifies the communication terminal 200 of the connection completion (S109). When communication terminal 200 receives the connection completion notification, user interface 510 shown in FIG. 4 is displayed. On the user interface 510, a comment 520 of "Connected to the detection device. Enjoy safe and comfortable driving." Is displayed as a push notification. As described above, the accident determination application starts automatically.
Note that the accident determination application is activated inside the communication terminal 200. Thereby, the power consumption of the communication terminal 200 is suppressed as compared with the activation of an application (which can be called a foreground) displayed on the screen. Therefore, the above-described processing makes it possible to easily provide an accident determination system with a very simple configuration, without bothering the driver and forgetting to start the accident determination application.

  When a plurality of communication terminals 200 exist in the vehicle, any one of the communication terminals 200 may change the setting to a state in which the communication terminal 200 is not connected to the detection device 100. For example, when two or more persons having the accident determination application installed in the communication terminal 200 get into the vehicle, the detection device 100 may connect to the communication terminal 200 of the person who first received the accident. In this case, a user interface 540 shown in FIG. 5 is displayed for the person whose connection has been confirmed. The user interface 540 displays that it is connected to the detection device 100. At this time, the person whose connection has been confirmed presses the button 560, whereby the connection between the detection device 100 and the communication terminal 200 is released.

  When a person (driver) who wants to start the accident determination application wants to start the connection between the communication terminal 200 and the detection device 100, the connection can be made manually. For example, a user interface 570 for connecting to the detection device 100 shown in FIG. 6 is displayed. At this point, a comment 580 indicating that the connection is not yet established with the detection device 100 is displayed. Therefore, when the driver presses button 590, communication terminal 200 can transmit a connection request notification for connecting to detection device 100. When the connection between the detection device 100 and the communication terminal 200 is completed, a connection completion notification is sent to the communication terminal 200. At this time, a user interface 600 shown in FIG. 7 is displayed. On the user interface 600, a comment 610 indicating "Connected to the detection device. Enjoy safe and comfortable driving."

  Note that when the battery level of the detection device 100 is low when the accident determination system is activated, the user interface 640 illustrated in FIG. 8 may be displayed. On the user interface 640, a comment 650 indicating that the remaining amount of the detection device is low is displayed. When the accident determination system is automatically started, a user interface 660 shown in FIG. 9 may be displayed. On the user interface 660, a comment 670 indicating that "the remaining amount of the detection device is low" is displayed.

(1-2-2. Accident judgment processing)
(1-2-2-1. Accuracy information with ID correct / wrong judgment)
FIG. 10 shows a flow of the accident determination process (S200). In the accident determination process, an ID-accelerated acceleration information right / wrong determination (S210) and acceleration information calculation and determination (S230) are performed.

  FIG. 11 shows a flow of the ID-accelerated acceleration information correctness determination (S210). First, the detection device 100 acquires acceleration information (S211). In the acceleration information, acceleration information in each of the X direction, the Y direction, and the Z direction is obtained. Also, identification information (ID) is generated (S213) so that the acceleration information can be determined individually, and is added to the acceleration information.

  Next, the acceleration information with the ID is transmitted to the communication terminal 200 (S215). When the communication terminal 200 receives the acceleration information with ID (S216), the data is judged to be correct (S217). The true / false determination here is to determine whether the data is missing (whether the data is consistent). For example, data is transmitted as 10-byte block data at a cycle of 10 Hz. At this time, if the acceleration information is missing, "0" is partially written. The acceleration information may be lost when the communication terminal 200 is connected to another Bluetooth (registered trademark) device at the same time, or when the communication terminal 200 is located in a place where radio waves of the Bluetooth Low Energy (registered trademark) communication are difficult to reach. Certain cases (in a duralumin suitcase) and the like.

  As described above, whether the data is correct or not is determined. If the data is normal (S217; OK), the process proceeds to the acceleration information calculation and determination (S230) processing flow. On the other hand, when the data is abnormal (S217; NG), a retransmission request notification is transmitted from the communication terminal 200 to the detection device 100 (S219). When the detection device 100 receives the retransmission request notification (S221), a retransmission instruction is issued in the detection device 100 (S223). An ID is generated again based on the instruction (S213). The above processing is repeated until data is transmitted normally (until it is confirmed that the block data is aligned). By performing the above processing, it can be said that all information for judging an accident is normal data.

(1-2-2-2. Accident judgment)
FIG. 12 shows a flow of acceleration information calculation and determination (S230).
First, the communication terminal 200 stores the received acceleration information (S231). FIG. 13 shows acceleration information of the vehicle 500. For example, the communication terminal 200 stores acceleration information AccX in the X direction, acceleration information AccY in the Y direction, and acceleration information AccZ in the Z axis direction for 0 to 3 seconds. FIG. 13 shows acceleration information every three seconds continuously up to 300 seconds.

  Subsequently, acceleration information is synthesized (S233). Synthesizing the acceleration information means, for example, synthesizing three-axis acceleration information. Specifically, as shown in Expression 1, this means adding the square of the acceleration information in the X direction, the square of the acceleration information in the Y direction, and the square of the acceleration information in the Z direction, and taking the square root. The resultant acceleration is represented as three-dimensional vector data as shown in FIG. Note that the synthetic acceleration information is the first information.

[Equation 1]
Synthetic acceleration = Sqrt (AccX ² + AccY ² + AccZ ² )

  Next, as shown in FIG. 15, only data of a specific frequency is extracted from the synthesized acceleration information (first information) (S235). For example, the specific frequency is preferably 7 Hz or more and less than 25 Hz. If the frequency is less than 7 Hz, the influence of the operation of the vehicle may occur, which is not preferable. Further, a frequency exceeding 25 Hz is difficult to measure with an acceleration sensor. Therefore, accident-specific information can be obtained by using the above frequency. When only a specific frequency is extracted from the combined acceleration information, a band-pass filter (for example, a high-pass filter) is used. Note that the extracted data is second information. The second information can also be called an extracted shock wave.

  Here, if it is determined that there is no second information that exceeds the threshold (S237; No), it is determined that there is no accident. On the other hand, when it is determined that there is the second information that exceeds the threshold (S237; Yes), the process proceeds to the next step.

Next, accumulation processing of the second information for a predetermined time, that is, integration processing is performed (S239). FIG. 16 shows integration data obtained by performing integration processing on the second information. In the extracted second information (extracted shock wave), the accident waveform converges over a time width of 0.5 seconds to 3.0 seconds. Therefore, when performing the integration process, it is preferable to perform the integration process within a time range of 0.5 seconds to 3.0 seconds. Incidentally, integrals data is the third information.

  Next, a second determination process is performed based on the obtained integral data (third information) (S241). The second determination process is performed by determining whether the value exceeds a set second threshold value. For example, 0.7 G or more and less than 4 G are used as the threshold. G is the gravitational acceleration.

  Here, the reason why the threshold is 0.7 G or more will be described below. For example, when traveling at 50 km / h (13.9 m / sec) on a dry road surface, the braking distance is 14.1 m. At this time, the gravitational acceleration G is about 0.7 G. Therefore, when an accident is determined, a gravitational acceleration of 0.7 G or more is applied. When the threshold value is 4G or more, it is determined that the threshold value is 4G.

  Here, when it is determined that the integral data does not exceed the threshold value (S241; No), it is determined that there is no accident (S245). On the other hand, when it is determined that the integral data exceeds the threshold (S241; Yes), it is determined that an accident has occurred (S243).

  By performing the above-described accident determination processing, it is possible to isolate factors other than the accident. For example, factors other than the accident include riding on a wheel stop in a parking lot, riding on a step, and joint noise on a highway or the like. Therefore, the accuracy of detecting an accident is dramatically improved by the above processing. Further, only the detection device 100 and the communication terminal 200 are used for the above processing. Therefore, the accident detection system has a highly accurate accident detection capability with a simple configuration.

  In addition, the range of the threshold value used for the accident determination may be provided in a stepwise manner. For example, a threshold value may be provided so that a dangerous behavior (a near miss) that did not result in an accident but could result in an accident can be determined. Thereby, dangerous behavior is detected, and advice for safe driving thereafter is displayed on the communication terminal 200.

(1-2-3. Accident report processing)
Next, an accident notification process when an accident occurs will be described. FIG. 17 shows a flow of the notification support processing. First, an accident is detected in the communication terminal 200 by the accident determination process (S301). At this time, a user interface 900 is displayed on the communication terminal 200 as shown in FIG. On the user interface 900, a comment 910 of "Accident detected" is displayed as a push notification. At this time, the user interface 900 is provided with an accident response support start button 920. The driver can easily contact a servicer such as an insurance company or road assistance by pressing the button 920. In addition, although not shown, the user selects not only an emergency request but also buttons such as “response pending (because the injured person is being rescued)” and “cancel (because of false detection)” and insurance. It can also be sent to the company. When there is no response from the driver, the insurance company can actively communicate by push notification, short message service (SMS), or telephone communication.

  When the button 920 is pressed, the communication terminal 200 starts an accident response support process (S303). At this time, the communication terminal 200 may also send a support request notification to the server 300 (S305). The server 300 that has received the notification starts the accident response processing (S307). Note that a user interface 930 is displayed on the communication terminal 200 as shown in FIG. On the user interface 930, a comment 940 "Please calm down first" is displayed. The user interface 900 is provided with a button 950 for contacting the insurance company.

  By pressing the button 950, a user interface 960 is displayed as shown in FIG. On the user interface 960, a confirmation comment 970 as to whether or not to make a telephone call is displayed. Further, a button 980 is provided on the user interface 960. By pressing button 980, the driver can contact an insurance company representative (eg, an accident receptionist).

With the above processing, even when an accident occurs, it is possible to quickly respond to the accident. Also, when an accident occurs, the driver can calm down and respond.
Note that the accident report may be used in the case of an accident that is not detected as an accident, a breakdown, and a trouble during running of the vehicle. For example, when the vehicle breaks down, the driver displays the user interface 1000 on the communication terminal 200. At this time, the button 1010 may be pressed for an accident, or the button 1020 may be pressed for a failure or trouble. This allows for immediate contact with the insurance company. In case of trouble, it can be requested directly from the road assistance servicer.

  Also, an accident report can be made by a person other than the driver. For example, when a failure occurs in the vehicle, the operation unit 160 (button) mounted on the detection device 100 is pressed. At this time, the accident determination application installed in the communication terminal 200 of a person other than the driver starts. At this time, the user interface 1000 shown in FIG. 21 is displayed. Persons other than the driver can contact the insurance company by pressing button 1020.

As described above, when an accident occurs, even if the driver cannot be contacted due to injury or is confused, the driver or a person other than the driver will check the insurance policy or driver's card through the app. be able to.
Therefore, the driver or a person other than the driver can deal with the accident without feeling troublesome. Since load assistance (failure / trouble) occurs more frequently than an accident, even if an accident is not detected, an environment can be set up by simply pressing the operation unit 160 (button) to activate the application and immediately request it. I can do it.
