Since the function of the general center server 30 may be realized in cooperation with the terminal device, there may be a function provided on the terminal device side.

The receiving unit 311 receives an incoming call from the drive recorder 10 addressed to a predetermined telephone number, identifies the telephone number of the drive recorder 10 by the calling number notification, and outputs the telephone number to the vehicle extraction unit 312. The receiving unit 311 transfers the incoming call from the drive recorder 10 to the terminal device of the operator who can handle the incoming call based on a predetermined rule.

FIG. 6 is a flowchart showing an example of a processing flow when the drive recorder 10 determines the presence or absence of an impact. The determination unit 1180A determines the presence or absence of an impact by repeating the processes from steps S51 to S61 shown in FIG. 6 while the power of the drive recorder 10 is ON.

The control unit 1180 acquires acceleration data and vehicle speed data (step S51). Specifically, in step S51, the control unit 1180 acquires acceleration data in the front-rear direction, the left-right direction, and the up-down direction measured by the acceleration measurement unit 1160. Further, the control unit 1180 acquires the moving speed of the vehicle 1000 calculated based on the time change of the absolute position of the vehicle 1000 measured by the positioning unit 1130 as vehicle speed data. When the vehicle speed data is included in the automatic diagnosis data acquired from the automatic diagnosis system 1400 mounted inside the vehicle 1000, the vehicle speed data is acquired from the automatic diagnosis data. The control unit 1180 that executes the process of step S51 corresponds to the acquisition unit, and the process of step S51 corresponds to the acquisition step.

The output value from the acceleration measuring unit 1160 is an acceleration in the direction opposite to the acceleration actually applied to the drive recorder 10. For example, it is assumed that a deceleration G of 0.6 G is applied to the drive recorder 10 by the driver stepping on the brake suddenly. In this case, the acceleration measuring unit 1160 outputs data indicating that an acceleration of 0.6 G has occurred in the forward direction (X direction shown in FIG. 3). In the following description, except for the description of the specific examples shown in FIGS. 6 and 11, the acceleration and deceleration do not mean the output value from the acceleration measuring unit 1160 but the acceleration and deceleration generated in the drive recorder 10. It shall be. Further, the deceleration means a negative acceleration.

After executing the process of step S51, the control unit 1180 determines whether or not the acceleration data and the vehicle speed data acquired in step S51 meet the determination criteria corresponding to the major accident, which is stored in the storage unit 1200. Judgment is made based on the reference data (step S52). Specifically, in the process of step S52, in the determination unit 1180A of the control unit 1180, the total value of the maximum value of the magnitude of the acceleration in the front-rear direction and the maximum value of the magnitude of the acceleration in the vertical direction is a predetermined threshold value ( The time when the maximum value of the acceleration in the front-rear direction is measured and the time when the maximum value of the acceleration in the vertical direction is measured, which is larger than the first threshold value, are within a predetermined period (first period). If it exists in (inside), it is judged that the judgment condition corresponding to the major accident is satisfied. The determination unit 1180A that executes the process of step S52 corresponds to the determination unit that determines which of the plurality of accident types the impact corresponds to, and step S52 is any of the plurality of accident types. Corresponds to the determination step of determining whether the impact corresponds to the accident type.

7 (A) and 7 (B) show an example of the acceleration detected by the acceleration measuring unit 1160 when a major accident occurs. The vertical axis shown in FIG. 7A shows the acceleration in the front-back direction, and the horizontal axis shows the time. The vertical axis shown in FIG. 7B shows the acceleration in the left-right direction, and the horizontal axis shows the time. The graph AC3 is the acceleration in the front-rear direction, and the graph AC4 is the acceleration in the left-right direction. In the process of step S52 shown in FIG. 6, the determination unit 1180A is the sum of the maximum value g1 of the acceleration in the front-rear direction shown in FIG. 7A and the maximum value g2 of the acceleration in the left-right direction shown in FIG. 7B. The time t3 in which the value is larger than the predetermined threshold value (first threshold value) and the maximum value g1 of the acceleration in the front-rear direction is measured and the time t4 in which the maximum value g2 of the acceleration in the left-right direction is measured are within the predetermined period ( If it exists within the first period), it is determined that the determination condition corresponding to the major accident is satisfied. The predetermined period (first period) may be predetermined, for example, 0.05 to 0.1 seconds, and may be set and changeable by the administrator. Further, the predetermined threshold value (first threshold value) may be, for example, about 6 to 8 G, but is not limited to this, and may be predetermined. The predetermined threshold value (first threshold value) may be set and changed by the administrator.

In the judgment criteria for major accidents, not only the acceleration values at the same time but also the acceleration values at different times are totaled, as in the judgment criteria for medium accidents (details will be described later). Tolerate. This is because the more serious the accident, the shorter the time it takes for the impact to occur, and the more likely it is that there will be slight deviations in the timing of the impact in the front-back direction and the left-right direction. This is because it is difficult to determine a major accident more accurately just by doing so. If a slight deviation occurs, it will not be possible to make an appropriate judgment by the method of synthesizing instantaneous values as in a medium accident, but the maximum values of acceleration in the front-back direction and left-right direction, that is, the values of acceleration at different times should be summed up. The problem is solved by allowing.

When it is determined in step S52 shown in FIG. 6 that the condition of the major accident is met (step S52; Yes), the control unit 1180 extracts low-resolution video data as extraction data (step S53). Specifically, in the process of step S53, the control unit 1180 has, for example, video data having a resolution that allows the operator of the general center to determine the necessity of a rescue request, that is, a video having a resolution that can determine the degree of injury. Extract the data. The video data includes video data captured by the recording unit 1140 and sound data recorded by the recording unit 1150, and the video data extracted in step S53 is internal video data. In addition to this, in step S53, for example, the date and time acquired from the clock, the position data acquired by the positioning unit 1130, the detected acceleration, the automatic diagnostic data acquired by the automatic diagnostic data acquisition unit 1170, and the like are extracted. May be good. Further, in step S53, device data such as a vehicle registration number and a telephone number are extracted according to the video data. Since the extracted data extracted in step S53 is stored in the storage unit 1200, the control unit 1180 that executes the process of step S53 corresponds to the recording unit, and the process of step S53 corresponds to the recording step. The video data having a low resolution corresponds to the video having the first image quality.

After executing the process of step S53, the control unit 1180 performs a transmission process (step S54). As a result, the extracted data extracted in step S53 is quickly transmitted to the cloud storage server. Then, the accident situation will be analyzed at the general center, and the accident response such as dispatching an ambulance will be carried out as needed. The transmission process is also performed in step S60, which will be described later. Since the cloud storage server is an area for each organization such as a general center for analyzing accidents and an insurance company to acquire the accident video, the control unit 1180 that executes the process of step S54 and the process of step S60 described later. Corresponds to the transmission unit, and the process of step S54 and the process of step S60 described later correspond to the transmission step.

When it is determined in step S52 of FIG. 6 that the acceleration data and vehicle speed data acquired in step S51 do not meet the determination criteria corresponding to a major accident (step S52; No), the determination unit 1180A is acquired in step S51. Whether or not the acceleration data and the vehicle speed data meet the determination criteria corresponding to the minor accident or the medium accident is determined based on the determination criteria data stored in the storage unit 1200 (step S55). Specifically, in the process of step S55, the determination unit 1180A calculates a moving average value for a predetermined period (second period) with respect to the magnitude of acceleration in the front-rear direction, and the calculated moving average value is a predetermined threshold value (second threshold value). ), And when it is detected that the deceleration of the vehicle speed is equal to or greater than the predetermined deceleration (first deceleration), it is determined that the criterion corresponding to the minor accident is satisfied.

FIG. 8A shows an example of the acceleration detected by the acceleration measuring unit 1160 when the driver who detects the accident suddenly steps on the brake to stop. Further, FIG. 8B shows an example of the acceleration detected by the acceleration measuring unit 1160 when the vehicle gets over the step. The vertical axis shows the acceleration in the front-back direction, and the horizontal axis shows the time. The period P1 indicates a predetermined period (second period) for calculating the moving average value. The threshold value P2 indicates a predetermined threshold value (second threshold value). Graphs AC1 and AC2 are anteroposterior accelerations, and graphs MA1 and MA2 are moving averages of anteroposterior accelerations. The predetermined period (second period) may be, for example, 0.5 seconds or the like, but is not limited thereto. Further, the predetermined threshold value (second threshold value) may be, for example, about 0.5 to 0.7 G, but is not limited thereto. The second period and the second threshold value may be predetermined as in the first period and the first threshold value, and may be set and changeable by the administrator.

In the example of FIG. 8A, the moving average value MA1 of the acceleration in the front-back direction exceeds the threshold value P2 at the timing of time t1. Therefore, the determination unit 1180A determines that the acceleration meets the determination criteria corresponding to the minor accident at the timing of time t1. On the other hand, in the example of FIG. 8B, the moving average value MA2 of the acceleration in the front-back direction does not exceed the threshold value P2. Therefore, the determination unit 1180A determines that the determination criteria corresponding to the minor accident are not met.

In the determination unit 1180A, the deceleration of the vehicle speed is a predetermined deceleration (first deceleration) in a predetermined time (third period) before and after the timing of the time t1 when the moving average value becomes larger than the predetermined threshold value (second threshold value). It may be determined whether or not the speed is equal to or higher than the speed). The predetermined time (third period) may be a time length such as, for example, 2 seconds or 3 seconds, but is not limited to this. Further, the determination unit 1180A may record the video data before and after the timing, assuming that the timing of the time t1 is the timing at which the impact for recording the video occurs.

As mentioned above, a minor accident is assumed to be a collision accident at an extremely low speed or a state in which the driver suddenly brakes and stops even if the accident does not occur. By detecting that a minor accident occurs when the moving average value of the magnitude of acceleration is a predetermined threshold value (second threshold value) and the deceleration is equal to or greater than the predetermined deceleration, minute vibration of the road is detected. This makes it possible to prevent erroneous determination as a minor accident.

In addition, it is possible to more accurately determine the deceleration by using the deceleration instead of the magnitude of the acceleration in the front-rear direction to indicate that the driver has applied the brake suddenly.

Further, in step S55 of FIG. 6, the determination unit 1180A sums the magnitude of the acceleration in the left-right direction and the magnitude of the acceleration in the front-rear direction at the same time, and when the total value is larger than the predetermined threshold value (third threshold value), It is judged that the judgment conditions corresponding to the medium accident are satisfied. The predetermined threshold value (third threshold value) may be, for example, about 2 to 4 G, but is not limited thereto. It should be noted that the third threshold value may be predetermined as in the first threshold value, and may be set and changeable by the administrator.

The determination unit 1180A regards the timing (not shown) at time t2 when the total value becomes larger than the predetermined threshold value (third threshold value) as the timing when the impact for recording the video occurs, and the video data before and after the timing. May be recorded.

In the judgment criteria corresponding to the middle accident, the accelerations in the left-right direction and the front-back direction are combined, and it is detected whether or not the combined value exceeds a certain value. This is because, unlike minor accidents, medium-sized accidents cause the acceleration to increase momentarily and decrease immediately when vehicles come into contact with each other. The determination unit 1180A that executes the process of step S55 corresponds to the determination unit that determines which of the plurality of accident types the impact corresponds to, and step S55 is any of the plurality of accident types. Corresponds to the determination step of determining whether the impact corresponds to the accident type.

When it is determined in step S55 that the conditions for a minor accident or a medium accident are met (step S55; Yes), the determination unit 1180A determines whether or not the type of the vehicle 1000 in which the drive recorder 10 is installed is a large vehicle. The indicated information is acquired, and it is determined whether or not the vehicle 1000 is a large vehicle (step S56). The type of the vehicle in which the drive recorder 10 is installed may be a type preset by the user via the user interface or the like provided in the drive recorder 10 when the drive recorder 10 is installed in the vehicle. The large vehicle means a vehicle such as a truck, a bus, a trailer, or the like.

When it is determined in step S56 that the vehicle 1000 is a large vehicle (step S56; Yes), the determination unit 1180A further determines whether the deceleration of the vehicle speed is equal to or greater than the predetermined deceleration (second deceleration). , Determining a sudden decrease in speed (step S57). The predetermined deceleration (second deceleration) may be the same value as the predetermined deceleration (first deceleration) described in the criterion for minor accidents, or may be a different value. good. The first deceleration and the second deceleration may be predetermined as in the first threshold value, and may be set and changeable by the administrator. In step S57, when the deceleration of the vehicle speed is equal to or greater than a predetermined deceleration (second deceleration), it may be determined that the deceleration is a rapid deceleration.

In a large vehicle, there is a possibility that a large impact may occur on the vehicle body due to loading and unloading of luggage, vibration during traveling due to loading a heavy object such as a vehicle, etc., but by providing the process of step S56, this may occur. It is possible to suppress the possibility of erroneous determination in such a case.

When it is determined in step S56 that the vehicle 1000 is not a large vehicle (step S56; No), or when it is determined in step S57 that the speed is suddenly reduced (step S57; Yes), the determination unit 1180A is further described below. It is determined whether or not at least one of the supplementary conditions to be added is satisfied (step S58). In step S58, if it is determined that at least one additional condition is met, the process proceeds to step S59, and if it is determined that all the additional conditions are not met, the process proceeds to step S61. Separately, the process may be shifted to the process of step S59 only when it is determined that all the supplementary conditions are satisfied, and the process may be shifted to the process of step S61 in other cases.

(Supplementary condition 1)
When the determination unit 1180A detects that the vehicle speed has become zero, it determines that an impact for recording an image has occurred. The timing for determining whether or not the vehicle speed is zero is, for example, after a predetermined time has elapsed (for example, after 10 seconds or 15 seconds) from the timing when it is determined that an impact for recording an image has occurred. May be good. This is because the vehicle usually stops when an accident occurs. In addition, if the vehicle speed is not zero at that timing, that is, if the vehicle is running, it is considered that no accident has occurred, so even if it is determined that the impact is not the one to record the image. good. That is, the supplementary condition 1 is that the vehicle speed is zero.

(Supplementary condition 2)
In the determination unit 1180A, the magnitude of the acceleration in the vertical direction exceeds a predetermined threshold value (fifth threshold value), and the magnitude of the acceleration in the vertical direction determines the magnitude of the acceleration in the vertical direction and the magnitude of the acceleration in the horizontal direction. When it is equal to or less than a predetermined ratio of the total values, it is determined that an impact for recording the image has occurred. That is, in the supplementary condition 2, the magnitude of the acceleration in the vertical direction exceeds a predetermined threshold (fifth threshold), and the magnitude of the acceleration in the vertical direction is the magnitude of the acceleration in the vertical direction and the magnitude of the acceleration in the horizontal direction. It is less than or equal to a predetermined ratio of the sum of the values. The predetermined threshold value (fifth threshold value) may be, for example, 0.1 G, but is not limited thereto. Further, the predetermined ratio may be, for example, 2%, but is not limited to this. The predetermined threshold value (fifth threshold value) and the predetermined ratio may be predetermined, and may be set and changeable by the administrator.

Basically, the larger the acceleration, the higher the possibility of an accident, but if a stronger acceleration occurs in the vertical direction compared to the acceleration in the horizontal direction, it is assumed that the vehicle just bounced up and down due to a step or the like. Because. By providing the supplementary provision condition 2, it is possible to suppress the possibility of erroneous determination in such a case.

(Supplementary condition 3)
Further, the determination unit 1180A should record an image when the total value of the magnitude of the acceleration in the left-right direction, the magnitude of the acceleration in the front-rear direction, and the acceleration in the up-down direction in a predetermined determination period is within a predetermined range. It may not be determined that the above has occurred. The predetermined determination period may be, for example, from 2 minutes before to the current time, but is not limited thereto. Further, the predetermined range is set to a range from the acceleration normally measured when the drive recorder 10 is correctly attached to the acceleration measured when the drive recorder 10 is about to peel off from the windshield. Is desirable. That is, the supplementary condition 3 is that the total value of the magnitude of the acceleration in the left-right direction, the magnitude of the acceleration in the front-rear direction, and the acceleration in the up-down direction in a predetermined determination period exceeds a predetermined range.

Among the cases where the drive recorder 10 falls off the windshield and falls regardless of the accident, the adhesive is peeling off before the fall and the drive recorder 10 is swaying for a long time. There are many. Therefore, by applying the supplementary condition 3, it is possible to suppress erroneous detection due to improper installation of the drive recorder 10.

When it is determined in step S58 that at least one additional condition is satisfied (step S58; Yes), the control unit 1180 extracts high-resolution video data as extraction data (step S59). Specifically, in the process of step S59, the control unit 1180 extracts, for example, video data having a resolution sufficient for the operator of the insurance company to calculate the accident error rate and the like. The video data includes video data captured by the recording unit 1140 and sound data recorded by the recording unit 1150, and the video data extracted in step S59 is internal video data and external video data. In addition, in step S59, for example, the date and time acquired from the clock, the position data acquired by the positioning unit 1130, the detected acceleration, the automatic diagnostic data acquired by the automatic diagnostic data acquisition unit 1170, and the like are extracted. May be good. Further, in step S59, device data such as a vehicle registration number and a telephone number are extracted according to the video data. Since the extracted data extracted in step S59 is stored in the storage unit 1200, the control unit 1180 that executes the process of step S59 corresponds to the recording unit, and the process of step S59 corresponds to the recording step. The high-resolution video data corresponds to the video of the second image quality.

After executing the process of step S59, the control unit 1180 performs a transmission process (step S60) and ends the process. As a result, the extracted data extracted in step S59 will be transmitted to the cloud storage server. Then, the accident situation is analyzed at the general center, and accident response such as road service and dispatch of ambulances is performed as necessary. The extracted data transmitted to the storage server in the cloud is also used by the insurance company. The insurance company calculates the accident error rate, etc. based on the extracted data.

On the other hand, when it is determined in step S55 that the determination criteria corresponding to a minor accident or a medium accident are not met (step S55; No), when it is determined in step S57 that the speed is not suddenly reduced (step S57; No), or in step S58. If it is determined that all the supplementary conditions are not met (step S58; No), the determination unit 1180A determines that the impact is not to be dealt with (step S61), and ends the process without extracting the extracted data.

FIG. 9 is a flowchart showing an example of the transmission process executed in steps S54 and S60 of FIG.

When the transmission process is started, the control unit 1180 transmits the extracted data extracted in step S53 in the transmission process in step S54 and the extracted data extracted in step S59 in the transmission process in step S60 to the cloud storage server (step). S102).

When the cloud storage server receives the extracted data from the drive recorder 10, it stores the received extracted data in a data storage area specified from, for example, a vehicle registration number or a telephone number included in the device data (step S103). In the transmission process in step S54, the process of step S103 is executed, so that in the event of a major accident, low-resolution video data that can reduce the processing load is quickly stored in the cloud storage server. .. Further, in the transmission process in step S60, by executing the process in step S103, high-resolution video data is stored in the cloud storage server regardless of the magnitude of the accident.

The control unit 1180 causes the positioning unit 1130 to acquire position data at regular intervals, determines whether or not the vehicle 1000 is moving each time, and is used, for example, when the vehicle moves by a predetermined distance (for example, 200 m) or more. Will stop the automatic call to the general center as it is not an accident.

That is, the control unit 1180 determines at any time whether or not the call stop condition is satisfied (step S104), and if the call stop condition is satisfied (step S104; Yes), the process is stopped (step S104). S105). If the call stop condition is satisfied before the extraction data is transmitted to the cloud storage server, the transmission of the extraction data may also be stopped.

On the other hand, when the call stop condition is not satisfied (step S104; No), the control unit 1180 causes the first communication unit 1110 to automatically make a call to the general center (step S106). In the event of an accident, the driver may be injured or may be upset and unable to speak, so even if the operator of the general center receives an incoming call, the machine voice will be played. The operator of the general center recognizes from the machine voice that the operation according to this embodiment is necessary.

In addition, if the operator of the general center deems it necessary, a callback will be made, so the driver and the operator will have a conversation at that time.

The automatic call to the general center and the transmission of the extracted data to the cloud storage server may be performed in parallel or may be performed in the reverse order of FIG.

The reception unit 311 of the general center server 30 receives an incoming call from the vehicle 1000 (step S107), and outputs the telephone number obtained by the caller ID notification to the vehicle extraction unit 312. The vehicle extraction unit 312 reads the contract data and access information by searching the contractor DB 313 by the telephone number, outputs the access information to the data acquisition unit 314, and outputs the contract data and the access information to the data output processing unit 316. do.

The data acquisition unit 314 requests the stored extraction data from the cloud storage server using the access information specified based on the telephone number (step S108).

When the cloud storage server receives the request for the extracted data from the general center server 30, it reads the extracted data from the data storage area specified by the access information and transmits it to the general center server 30 (step S109).

When the data acquisition unit 314 receives the extracted data from the cloud storage server, the data acquisition unit 314 stores the extracted data in the data storage unit 315 (step S110). Then, the data output processing unit 316 causes the terminal device determined by the receiving unit 311 to display the extracted data and the contract data (step S111).

FIG. 10 shows a configuration example of a display screen in the terminal device. In the example of FIG. 10, the contract data display field 3101, the video display field 3102, the analysis instruction button 3103, the fear level setting value display field 3104, the fear level setting value up button 3105, and the fear level setting value down button 3106 , Fear level setting button 3107, analysis result display column 3108, vehicle data (device data and impact event data) display column 3109, callback instruction button 3110, load service request button 3111, and rescue request button 3112. A response data input field 3113, an end button 3114, a registration button 3115, and the like are included.

In the contract data display field 3101, at least a part of the data extracted from the contractor DB 313 is displayed. The video data received from the vehicle 1000 is displayed in the video display field 3102. At least a part of the device data and the impact event data is displayed in the display column 3109 of the vehicle data (equipment data and impact event data). After listening to the machine voice sent from the drive recorder 10, the operator of the terminal device confirms the information displayed on such a display screen, and causes an accident such as the need for a callback or contact with an emergency agency. Determine the need for action.

Further, the operator of the terminal device visually recognizes the video data displayed in the video display field 3102, and determines whether or not the video data is a shocking video such as a fatal accident, that is, a horror video. For example, the operator of the terminal device determines whether or not the image is a fear image according to a predetermined manual, and if it is determined that the image is a fear image, the operator sets the fear level setting information indicating that the image is a fear image. Specifically, the operator of the terminal device has, for example, a fear level of "3" for a video of a fatal accident, a fear level of "2" for a video with heavy bleeding, and a fear level of "1" for a video with only a fracture. Click the fear level up button 3105 or the fear level set value down button 3106 according to the fear level to display the fear level setting value according to the fear level in the fear level setting value display field 3104. , By clicking the fear degree setting button 3107, the fear degree setting information of the fear degree setting value is set. The fear level setting value is set to "0" as an initial value. In this embodiment, when the fear level setting value is set to "1" or more, the fear level setting information indicates that the image is a fear level, and the fear level setting value is set to "0". In some cases, the fear level setting information indicates that the image is not a fear image. As will be described in detail later, the fear level setting information is associated with the video data, identification information for identifying the accident, information such as the date and time when the accident occurred, and is registered in the cloud storage server. The fear degree setting values of the fear degree "0" to "3" correspond to the setting values of a plurality of stages according to the fear degree of the fear image. By setting the fear level setting value in this way, it is possible to reduce the mental burden on the operator by visually recognizing a shocking image when analyzing the accident situation at the insurance company.

Regarding the countermeasure data input field 3113, predetermined items (for example, no accident / accident) may be input by a check box.

Further, in this embodiment, for example, when the operator clicks the analysis instruction button 3103, the input processing unit 317 causes the analysis processing unit 318 to perform the analysis processing (step S112), as shown in FIG. The analysis process may be automatically executed without the instruction of the operator.

An example of the analysis process will be described with reference to FIGS. 11 and 12. FIG. 11 is a flowchart showing an example of the analysis process when the transmission process is performed via step S54. Further, FIG. 12 is a flowchart showing an example of the analysis process when the transmission process is performed via step S60. Since the transmission process is performed via step S54 when there is a high urgency of responding to an accident such as saving lives in a major accident, the analysis process when the transmission process is performed via step S54 is performed on human life. Only the matters necessary for rescue are analyzed, the processing burden is reduced, and early accident response is possible.

In the analysis process shown in FIG. 11, the analysis processing unit 318 searches for a predetermined collision sound from, for example, sound data, and depending on the presence or absence of the predetermined collision sound, the presence or absence of an accident (more specifically, the probability of an accident. For example, the level of possibility of an accident, etc.) is determined, and the determination result is output to the data output processing unit 316 as an analysis result (step S31).

After executing the process of step S31, the analysis processing unit 318 extracts passenger information from the internal video data (video data inside the vehicle 1000 taken by the recording unit 1140), and the data output processing unit as the analysis result. Output to 316 (step S34). For example, using face recognition technology, the number of passengers, the age group of passengers, the boarding position, and the like are extracted. This information is used by the operator to determine the necessity of a rescue request.

On the other hand, in the analysis process shown in FIG. 12, as in the analysis process shown in FIG. 11, the analysis processing unit 318 searches for a predetermined collision sound from, for example, sound data, and causes an accident depending on the presence or absence of the predetermined collision sound. (More specifically, the probability of an accident. For example, the level of possibility of an accident, etc.) is determined, and the determination result is output to the data output processing unit 316 as an analysis result (step S31).

Then, the analysis processing unit 318 specifies the distance to the external object (object other than the vehicle 1000) from the external video data (video data outside the vehicle 1000 taken by the recording unit 1140), and the analysis processing unit 318 with respect to the external object. The presence or absence of an accident (more specifically, the probability of an accident) is determined based on the distance (for example, the shortest distance), and the determination result is output to the data output processing unit 316 as an analysis result (step S32).

Further, the analysis processing unit 318 determines the possibility of self-propelling, the need for repair, and the like from the automatic diagnosis data, and outputs the determination result as the analysis result to the data output processing unit 316 (step S33). For example, the necessity of a tow truck (self-propelled possibility) and whether repair is necessary even if it is self-propelled are determined from the presence or absence of engine damage, battery damage, and fuel system damage.

Further, the analysis processing unit 318 extracts passenger information from the internal video data (video data inside the vehicle 1000 taken by the recording unit 1140) and outputs the analysis result to the data output processing unit 316 (step S34). ). For example, using face recognition technology, the number of passengers, the age group of passengers, the boarding position, and the like are extracted. This information is used by the operator to determine the necessity of a rescue request.

These are examples of analysis processing, and different processing may be added. For example, as for the acceleration data, the value of each axis is obtained in the case of the 3-axis sensor, but the collision direction, the collision location in the vehicle, and other information may be extracted based on them. Further, instead of performing analysis processing for each data type, the probability of an accident or the like may be comprehensively determined. In addition, you may want to do some, but not all, of these.

Returning to FIG. 9, when such an analysis process is performed, the data output processing unit 316 displays the analysis result in the analysis result display column 3108 shown in FIG. 10 (step S113).

Based on such display contents, the operator determines whether a response including a callback or the like is necessary. If it is determined that the response including the callback etc. is unnecessary, the end button 3114 is clicked. The input processing unit 317 determines that no response is required (step S114: No route) in response to the end instruction, and ends the subsequent processing. In this embodiment, when the response including the callback or the like is unnecessary, the process of step S209 (see FIG. 13) described later is not executed, and the fear degree setting value is not set (that is, the initial value). (It is "0" in the above and it is not a fear image depending on the fear level setting information), but for example, even when a response including a callback or the like is unnecessary (step S114: No route), step S209 is also shown. Processing may be executed, and then the processing may be terminated.

On the other hand, if the operator determines that a response including a callback or the like is necessary, the operator clicks, for example, the callback instruction button 3110. Then, the input processing unit 317 determines that correspondence is required (step S114: Yes route), and the processing shifts to the processing of FIG. 13 or FIG. 14 via the terminal A. If the transmission process is performed via step S54, the process proceeds to the process shown in FIG. 13, and if the transmission process is performed via step S60, the process proceeds to the process shown in FIG.

FIG. 13 is a flowchart showing an example of processing when the callback instruction button 3110 is clicked when the transmission processing is performed via step S54, and FIG. 14 is a flowchart in which the transmission processing is performed via step S60. In this case, it is a flowchart which shows an example of the processing when the callback instruction button 3110 is clicked.

As described above, the transmission process is performed via step S54 when the urgency of responding to an accident such as lifesaving in a major accident is high, and therefore, when the transmission process is performed via step S54. In the processing, only the matters necessary for saving lives, that is, the matters related to the dispatch of ambulances, are performed to reduce the processing burden and enable early accident response.

In the process of FIG. 13, the input processing unit 317 outputs the telephone number of the drive recorder 10 to the call processing unit 321 and makes a call to the telephone number to make a call (step S200).

The operator and the driver or passenger of the vehicle 1000 confirm the situation in a call. Specifically, it is confirmed whether or not an accident has occurred, whether or not there is an injury, and if it is determined that rescue is necessary from the call, the rescue request button 3112 shown in FIG. 10 is clicked.

When the rescue request button 3112 is clicked, the input processing unit 317 determines that the rescue is requested (step S205: Yes route), and accesses the external notification processing unit 319 with the extracted data, as shown in FIG. Information, contact personal data, etc. are notified to the emergency agency system (step S206). The notification may include passenger information (analysis result or confirmation result by telephone (degree of injury, etc.)). At the same time, you may call the emergency agency. If the rescue is not requested (step S205: No route), the process is terminated.

The emergency agency system receives the access information of the extracted data, the contact personal data, and the like from the general center server 30 and stores them in the data storage unit (step S207). The rescue organization dispatches an ambulance based on the data stored in the cloud storage server (step S208).

After taking such measures, the operator of the terminal device inputs, for example, the handling data such as the presence or absence of a rescue request in the handling data input field 3113 of FIG. 10, and clicks, for example, the registration button 3115. Then, the handling data input from the terminal device is output to the input processing unit 317 of the general center server 30.

When a major accident occurs, transmission processing is performed via step S54, and low-resolution video data is quickly transmitted to the cloud storage server as extracted data. Then, based on the extracted data, the accident response regarding lifesaving will be carried out as soon as possible. Therefore, the processing load can be reduced and the speed of accident response can be ensured.

Moving on to the description of the process of FIG. 14, in response to the click of the callback instruction button 3110, the input processing unit 317 outputs the telephone number of the drive recorder 10 to the call processing unit 321 as in the process of FIG. Then, a call is made by calling the telephone number (step S200).

The operator and the driver or passenger of the vehicle 1000 confirm the situation in a call. Specifically, it confirms whether an accident has occurred, whether there is an injury, etc., and confirms the necessity of road service (necessity of a tow truck, necessity of repair, etc.). At this point, various advice may be given to the driver or passenger.

If it can be confirmed that there is no accident, the process is terminated by inputting, for example, no accident in the countermeasure data input field 3113 shown in FIG.

If the occurrence of an accident is confirmed, for example, the occurrence of an accident is input in the countermeasure data input field 3113. When the details of the accident are heard, the details may be input to the coping data input field 3113. On the other hand, if the operator determines that the road service is necessary from the call, the operator clicks the road service request button 3111.

Returning to FIG. 8, when the load service request button 3111 is clicked, the input processing unit 317 determines that the load service is requested (step S201: Yes route), and accesses the external notification processing unit 319 with the extracted data. Information, contact personal data (telephone number of drive recorder 10 and the like) and the like are notified to the road service provider system (step S202). The notification may include data on self-propellability and repairability (analysis result, confirmation result by telephone, etc.). At the same time, you may call the road service provider.

The road service provider system receives the access information of the extracted data, the contact personal data, and the like from the general center server 30 and stores them in the data storage unit (step S203). The road service provider implements the road service based on the data stored in the storage server of the cloud (step S204). For example, the drive recorder 10 is called to dispatch a tow truck or other vehicle to a position included in the device data.

Whether the load service is not requested (step S201: No route) or the road service is requested (step S201: Yes route), if the operator determines that rescue is necessary from the call, the rescue request shown in FIG. 10 is performed. Click button 3112.

When the rescue request button 3112 is clicked, the input processing unit 317 determines that the rescue is requested (step S205: Yes route), and accesses the external notification processing unit 319 with the extracted data, as shown in FIG. Information, contact personal data, etc. are notified to the emergency agency system (step S206). The notification may include passenger information (analysis result or confirmation result by telephone (degree of injury, etc.)). At the same time, you may call the emergency agency. If the rescue is not requested (step S205: No route), the process proceeds to step S209.

The emergency agency system receives the access information of the extracted data, the contact personal data, and the like from the general center server 30 and stores them in the data storage unit (step S207). The rescue organization dispatches an ambulance based on the data stored in the cloud storage server (step S208).

After taking such measures, the operator of the terminal device inputs, for example, the handling data such as whether or not a road service is requested and whether or not a rescue is requested in the handling data input field 3113 in FIG. 10, and presses, for example, the registration button 3115. click. Then, the handling data input from the terminal device is output to the input processing unit 317 of the general center server 30.

Whether requesting rescue (step S205: No route) or requesting rescue (step S205: Yes route), the operator is a horror image from the image data displayed in the image display field 3102 shown in FIG. It is determined whether or not the fear level is set, and the fear level setting value up button 3105, the fear level setting value down button 3106, or the like is clicked to set the fear level setting value (step S209). The video data for which the fear degree setting value is set in step S209 is high-resolution video data extracted in step S59 of FIG.

Specifically, in step SNS209, when the fear level setting value up button 3105 or the fear level setting value down button 3106 is clicked, the fear level value (fear level setting value) displayed in the fear level setting value display field 3104 is displayed. Changes. Then, when the operator clicks the fear degree setting button 3107, the fear degree setting value is set.
