Description

The present invention relates to a report preparation support system, a server device, and a computer program that support the preparation of a report for dealing with an abnormality of a road.

Conventionally, roads have been divided into a plurality of unit sections for inspection based on kilometer posts, and inspection reports have been created for each unit section. For example, in the inspection report creation support device disclosed in Japanese Patent Application Laid-Open No. 2018-147314, an inspection vehicle travels on a road in a unit section to be inspected, and the road is imaged by a digital video camera mounted on the inspection vehicle. The inspection report creation support device stores each road image data in which the road is continuously imaged by a digital video camera and the imaged position (kilopost value) of each road image data in association with each other.

When the inspection report creation support device receives the designation of an arbitrary unit interval from the user, the inspection report creation support device reads the data of the specified unit section from the stored data and displays the road image data on the screen. The user visually checks the road image data displayed on the screen and determines whether or not there is an abnormality such as a pothole. When the user discovers an abnormality on the road, he / she clicks the deformation judgment icon displayed on the screen. The inspection report creation support device determines that the deformation has been confirmed by the user when the deformation determination icon is clicked, and stores the kilometer post value and the road image data for the road on which the deformation has been confirmed in association with each other. The inspection report creation support device creates an inspection report based on the stored kilometer post value and road image data.

However, the accuracy of the sensors attached to the vehicle varies from vehicle to vehicle. Therefore, the report creation support system 1 executes provisional registration of information indicating a road abnormality and confirmation of registration after provisional registration (hereinafter, may be referred to as main registration) according to the accuracy of the sensor. In the present embodiment, the accuracy of the second sensor 8 of the second vehicle 5 is higher than the accuracy of the first sensor 7 of the first vehicle 4. Then, the report creation support system 1 executes the provisional registration based on the detection information by the low-precision first sensor 7, and executes the main registration based on the detection information by the high-precision second sensor 8. The "accuracy of the sensor" in the present application is not limited to, for example, a value indicating the high performance of the same type of sensor, and even for different types of sensors, a certain event (road abnormality such as road surface unevenness). It means the high accuracy that can detect the event when it is used as a means to detect. Therefore, the high-precision second sensor 8 has higher accuracy than the low-precision first sensor 7, for example, when used as a means for detecting unevenness on the road surface (when a detection signal is used). It is a sensor that can detect the unevenness of.

FIG. 4 shows the relationship between the road abnormality to be detected and the sensor. In the following description, in order to give a detailed explanation as appropriate according to the type of road abnormality, for convenience of explanation, each type of road abnormality will be referred to as a first embodiment, a second embodiment, and a third embodiment. .. As shown in FIG. 4, the first embodiment is a case where provisional registration and main registration of information on unevenness of the road surface is performed as a road abnormality. The second embodiment is a case where information on obstacles on the road is provisionally registered as a road abnormality. Further, the third embodiment is a case where information on a decrease in μ (friction coefficient) of the road surface is provisionally registered as a road abnormality. The type of road abnormality of the present application is not limited to the above type, and various events affecting the use of the road such as peeling of asphalt and cracking of the road can be adopted.

As shown in FIG. 4, as the first sensor 7 for detecting the unevenness of the road surface of the first embodiment, for example, a vehicle speed sensor can be adopted. As shown in FIG. 3, the navigation device 6 of the first vehicle 4 is connected to the first sensor 7 and inputs a detection signal from the first sensor 7. The vehicle speed sensor (first sensor 7) generates a pulse according to the rotation of the driving wheels of the vehicle, and outputs the pulse signal to the navigation ECU 44, for example. The navigation ECU 44 can calculate the wheel speed (rotational speed) and the moving distance of the drive wheels by counting the pulses of the input pulse signal. The navigation ECU 44 estimates the unevenness of the road surface based on, for example, fluctuations in wheel speed. For example, the navigation ECU 44 calculates the magnitude of a specific frequency from the output of the vehicle speed sensor as the degree of vibration, and estimates the unevenness of the road surface by fuzzy inference based on the parameters of the calculation result. Further, as the second sensor 8 for detecting the unevenness of the road surface, for example, a vertical acceleration sensor for detecting the vertical acceleration acting on the wheels of the second vehicle 5 can be adopted. The navigation ECU 44 of the navigation device 6A of the second vehicle 5 estimates the unevenness of the road surface based on, for example, the fluctuation of the vertical acceleration detected by the vertical acceleration sensor (second sensor 8).

Further, as shown in FIG. 4, as the first sensor 7 for detecting an obstacle on the road of the second embodiment, for example, a sensor for detecting sudden steering or sudden deceleration of a vehicle can be adopted. Specifically, as the first sensor 7 for detecting sudden steering, a steering sensor that detects the rotation angle of the steering from the neutral position and outputs a signal indicating the detected rotation angle (steering angle) can be adopted. it can. Further, as the first sensor 7 for detecting sudden deceleration, a vehicle speed sensor can be adopted. The navigation ECU 44 detects sudden steering or sudden deceleration based on signals input from the steering sensor or the vehicle speed sensor (first sensor 7). For example, when the rate of change of the steering angle per unit time is equal to or greater than the reference rate of change, the navigation ECU 44 determines that the steering is abruptly rotated. Further, the navigation ECU 44 determines that the deceleration is a sudden deceleration in which the brake is suddenly stepped on when the rate of decrease in vehicle speed per unit time is equal to or greater than the reference rate of change. When the driver makes sudden steering or deceleration, there is a high possibility that there is an obstacle on the road (on the road surface) on which the driver is traveling. Therefore, the navigation device 6A (navigation ECU 44) of the second vehicle 5 estimates the point where sudden steering or sudden deceleration is detected as a road abnormal position where there is an obstacle on the road.

Further, as the second sensor 8 for detecting an obstacle on the road, for example, an in-vehicle camera can be adopted. The in-vehicle camera is composed of a camera using a solid-state image sensor such as a CCD, and is attached to the bumper of the second vehicle 5, the back side of the rearview mirror, the door mirror, etc., and can image the surrounding environment of the second vehicle 5. The optical axis direction is set to. The number of in-vehicle cameras may be singular or plural. For example, the in-vehicle camera captures the surrounding environment in front of the vehicle in the traveling direction when the second vehicle 5 is traveling. The in-vehicle camera may have an imaging range of the side or the rear of the second vehicle 5 instead of the front in the traveling direction. The navigation device 6A (CPU61A) of the second vehicle 5 processes, for example, image data in front of the vehicle captured by the in-vehicle camera (second sensor 8), and an object having a predetermined size or larger is on the road surface or the like. Judge whether or not. When the navigation device 6A detects an object having a predetermined size or larger, the navigation device 6A estimates the point as a road abnormal position where there is an obstacle on the road.

Further, as shown in FIG. 4, as the first sensor 7 for detecting the decrease in the road surface μ of the third embodiment, for example, a sensor for detecting the operation of the antilock braking system (ABS) may be adopted. it can. The μ (coefficient of friction) of the road surface decreases due to rain, snow, freezing, etc. Alternatively, the μ of the road surface decreases even when oil or the like is sprinkled on the road surface due to an accident. Then, when the μ of the road surface is lowered, there is a high possibility that the ABS will operate in order to reduce the occurrence of sliding due to the lock of the wheels in the braking operation on the low friction road. In other words, the point where the ABS is activated is likely to be an abnormal road position where the road surface μ is lowered. Therefore, the navigation device 6 of the first vehicle 4 estimates the point where the operation of the ABS is detected by the first sensor 7 as the abnormal road position where the road surface μ is lowered.

Further, as the second sensor 8 for detecting the decrease in the road surface μ, for example, an in-vehicle camera can be adopted. The navigation device 6A of the second vehicle 5 processes, for example, image data of the road surface captured by the in-vehicle camera (second sensor 8) attached to the front glass of the second vehicle 5, and performs image processing on the image data of the road surface, such as a puddle, snow, freezing, and oil. Judge the existence of an object that reduces μ such as. When the navigation device 6A detects an object that lowers μ, it estimates that point as an abnormal road position where the road surface μ is lowered. In each of the above-described embodiments, the accuracy of the result of estimating the road abnormality by the second sensor 8 is higher than the accuracy estimated by the first sensor 7.

The road abnormality to be detected and the types of the first and second sensors 7 and 8 shown in FIG. 4 are examples. For example, the above-mentioned method for estimating the unevenness of the road surface is an example, and other known techniques can be adopted. For example, a suspension sensor that detects the amount of expansion and contraction (displacement amount of the suspension arm) of the suspension device of the wheel and a vehicle height sensor that detects the amount of displacement of the vehicle height are used as the first sensor 7 to obtain the amount of displacement of the suspension arm. The unevenness of the road surface may be estimated from the difference in the amount of displacement of the vehicle height.

In the following explanation, in order to make the explanation easy to understand, the case where the report creation support system 1 provisionally registers and mainly registers the unevenness of the road surface as the road abnormality, which is the first embodiment, will be mainly described, and the second and second 3 The description of the embodiment will be omitted as appropriate. The report creation support system 1 can execute temporary registration and the like for the second embodiment and the third embodiment as well as the first embodiment. In addition, the report creation support system 1 can collectively process a plurality of types of road abnormalities. That is, not only the detection information of the unevenness of the road surface but also the detection information of the obstacle of the road and the decrease of the road surface μ may be collected from the first vehicle 4 at the same time or in parallel.

The navigation device 6 of the first vehicle 4 temporarily registers the information on the unevenness of the road surface detected by the first sensor 7 in the probe information DB 22 of the server device 3. Then, the navigation device 6A of the second vehicle 5 moves to the temporarily registered road abnormal position based on the guidance by the server device 3 as described later, and based on the information on the unevenness of the road surface detected by the second sensor 8. , The main registration is performed in the probe information DB 22 of the server device 3. FIG. 5 is a diagram showing an example of probe information stored in the probe information DB 22. As shown in FIG. 5, the probe information includes information related to the above (a) to (e). For example, the first line of the probe information shown in FIG. 5 shows the case where the first vehicle 4 with the ID “A1” enters the link with the ID “100001” at 9:01 on February 7, 2019. The detection information detected by the first sensor 7 in the position coordinates (x1, y1) of the first vehicle 4 traveling in the above is stored. The detection information of the first sensor 7 referred to here is, for example, data indicating the result of estimating that the road surface has irregularities. The sensor information is not limited to data showing the result of estimating that there is unevenness, for example, the value of the wheel speed detected by the vehicle speed sensor (first sensor 7), the fluctuation distribution of the wheel speed, the result of fuzzy inference, and the unevenness. Data indicating the degree or the like may be used. Further, the sensor information may include data indicating the result of estimating that there is no unevenness, or data of the detected value that is estimated to have no unevenness.

In the first line of the probe information shown in FIG. 5, only the detection information of the first sensor 7 is provisionally registered, and the detection information of the second sensor is not fully registered. On the other hand, in the second line, when the second vehicle 5 with the ID "B211" enters the link with the ID "100012" at 13:30 on January 3, 2019, the second vehicle traveling on the link The detection information detected by the second sensor 8 with the position coordinates (x20, y2) of 5 is stored. Then, after the detection information of the first sensor 7 is provisionally registered at 11:30 on January 3, 2019, the detection information of the second sensor 8 is finally registered.

Further, as shown in FIG. 5, in addition to the information related to the above (a) to (e), vehicle image data is stored in association with the data in the second row of the main registration. The vehicle image data is image data obtained by capturing an abnormal road position (unevenness of the road surface, etc.) by the second vehicle 5 equipped with the in-vehicle camera as the second sensor 8. As will be described later, the navigation device 6A of the second vehicle 5 registers the vehicle image data in which the abnormal road position is captured at the time of the main registration (S32 in FIG. 7). The server device 3 stores the vehicle image data in the probe information DB 22 in association with the information of the temporary registration and the main registration. The stored vehicle image data is used in the road abnormality position display process (S62, S63 in FIG. 9), which will be described later.

Here, in general, the price of the high-precision second sensor 8 capable of estimating (detecting) a road abnormality with high accuracy is higher than the price of the low-precision first sensor 7. Therefore, the price of the second vehicle 5 equipped with the second sensor 8 is likely to be higher than the price of the first vehicle 4 equipped with the first sensor 7. If the second vehicle 5 is a so-called luxury vehicle, a repair vehicle for repairing a road, or a patrol vehicle, the total number of the second vehicles 5 traveling on the road is compared with the total number of the first vehicles 4 having a low price. Will decrease. Therefore, in the report creation support system 1 of the present embodiment, the detection information by the low-precision first sensor 7 is temporarily registered, and the second vehicle 5 is guided to the provisionally registered road abnormality position, so that the high-precision first sensor 7 is used. 2 When a road abnormality is detected by the sensor 8, the main registration is performed. As a result, the reliability of the data registered in the probe information DB 22 can be improved.

Further, the server device 3 displays the information on the abnormal road position registered in the probe information DB 22 on the screen of the communication terminal 10 that has accessed the server device 3. For example, the worker 9 confirms the abnormal road position he / she is in charge of from the displayed abnormal road position, and moves by an inspection vehicle or the like. When the worker 9 takes measures such as repairing or inspecting the road, the worker 9 selects the corrected road abnormality position from the display screen of the communication terminal 10 and inputs the information necessary for creating the report. As a result, the server device 3 can execute the automatic creation of the report. The server device 3 stores the created report in the report DB 24. The method of utilizing the road abnormality information registered in the probe information DB 22 is not limited to the method of displaying the information on the communication terminal 10 described above. For example, the server device 3 may provide the road abnormality information registered in the probe information DB 22 as reference information for road repair to the ministries and agencies that manage the road. As a result, the ministries and agencies that manage the road can dispatch vehicles and patrol cars for repairing the road to the abnormal position of the road, and can promptly take appropriate measures such as repairing the road and guiding the traveling vehicle.

Next, the schematic configuration of the communication terminal 10 possessed by the worker 9 will be described with reference to FIG. In the following description, a case where the communication terminal 10 is a smartphone will be described as an example. As shown in FIG. 6, the communication terminal 10 transmits / receives signals to / from the CPU 71, the memory 72, and the transmission / reception circuit unit (RF) 73 that transmits / receives signals between the base station of the communication network 11 and the data bus BUS. An input / output unit that is an interface between a baseband processing unit 74 that converts an RF (Radio Frequency) signal received in the circuit unit 73 into a baseband signal and a baseband signal into an RF signal, and a microphone 75, a speaker 76, and the like. It is configured by connecting 77, a display 78 composed of a liquid crystal display panel or the like, a camera 79, an input operation unit 80 composed of a touch panel, hard buttons, or the like, and a GPS 81.

Here, the CPU 71 built in the communication terminal 10 is a control means of the communication terminal 10 that executes various operations according to a program stored in the memory 72, and constitutes the communication terminal ECU 82 together with the memory 72. Further, various processing contents of the communication terminal ECU 82 are displayed on the display 78 as needed.

Further, the memory 72 is a storage medium for storing terminal information and the like. The terminal information is the ID of the communication terminal 10 or the information (user ID, name, etc.) of the worker 9 who owns the communication terminal 10. Further, in the memory 72, in addition to the control program, various application programs including the report creation processing program (see FIG. 9) described later are also stored. The memory 72 may be configured by a hard disk, a memory card, or the like.

Further, the display 78 is arranged on one surface of the housing, for example, and a liquid crystal display, an organic EL display, or the like is used. Then, a top screen for executing various applications installed on the communication terminal 10, screens related to the executed applications (Internet screen, mail screen, etc.), various information such as images and moving images are displayed. In addition, when the report creation support processing program (report creation processing program in FIG. 9) is activated, a remarks column for inputting input information necessary for creating a report, a send button for determining data transmission, etc. ( (See FIG. 11) is also displayed.

Further, the camera 79 is a small image pickup device composed of a camera using a solid-state image pickup device such as a CCD, and is built in the back side of the communication terminal 10. Then, the user can operate the input operation unit 80 while the dedicated application program is started to take an image of the surroundings. In the present embodiment, in particular, the state of the road abnormal position that the worker 9 has dealt with is imaged by the camera 79, and the image data (an example of the coping image data of the present application) captured is used for creating the report. The image data captured by the camera 79 is stored in the memory 72.

Further, the input operation unit 80 is composed of a touch panel provided on the front surface of the display 78, hard buttons arranged on the housing, and the like. Then, the communication terminal ECU 82 controls to execute various corresponding operations based on the electric signal output by pressing the touch panel or the hard button of the input operation unit 80. Further, in the present embodiment, in particular, the input operation unit 80 receives the operation of the decision button displayed on the display 78 from the worker 9 in the report creation process. The input operation unit 80 can also be configured by various keys such as a number / character input key, a cursor key for moving the cursor for selecting the displayed content, and a decision key for confirming the selection.

Further, the GPS 81 can detect the current position and the current date and time of the communication terminal 10 (that is, the worker 9) by receiving the radio wave generated by the artificial satellite. Further, in addition to the GPS 81, another device (for example, a gyro sensor or the like) for detecting the current position and orientation of the communication terminal 10 may be provided.

Subsequently, the navigation device 6 of the first vehicle 4 included in the report creation support system 1 having the above configuration and the temporary registration processing program executed by the server device 3 will be described with reference to FIG. 7. FIG. 7 is a flowchart of the temporary registration processing program and the main registration processing program according to the present embodiment. First, the temporary registration processing program shown in FIG. 7 will be described, and the main registration processing program will be described later. Here, the temporary registration processing program is executed, for example, when the power of the navigation device 6 of the first vehicle 4 is turned on and the traveling of the first vehicle 4 is started. The temporary registration processing program is a program that is executed after a predetermined time (for example, several minutes) has elapsed from the time when the previous program was terminated, estimates the road condition, and executes temporary registration of the abnormal road position. The program shown in the flowchart in FIG. 7 below is stored in, for example, a RAM 62, a ROM 63, or the like included in the navigation device 6, and is executed by the CPU 61.

Further, the temporary registration processing program is executed, for example, by starting a predetermined application program when the system is started in the server device 3, and processing is performed when the information on the abnormal road position is received from the navigation device 6 of the first vehicle 4. To be started. The temporary registration processing program is a program that temporarily registers the information received from the first vehicle 4 in the probe information DB 22 and transmits the information on the passing route to the subsequent second vehicle 5 that passes through the temporarily registered abnormal road position. .. The program shown in the flowchart in FIG. 7 below is included in the report creation support processing program stored in the RAM 32 and ROM 33 included in the server device 3, and is executed by the CPU 31.

First, in step 1 (hereinafter abbreviated as S) 1 shown in FIG. 7, the CPU 61 of the navigation device 6 of the first vehicle 4 estimates the road abnormality based on the detection information detected by the first sensor 7. For example, in the first embodiment, the CPU 61 estimates whether the road surface on the road on which the first vehicle 4 is traveling has irregularities based on the fluctuation of the wheel speed detected by the vehicle speed sensor (first sensor 7). .. For example, when the first vehicle 4 travels on a road surface having holes, a road surface having irregularities, or a road surface having a step in a manhole, the wheel speed fluctuates, so that the CPU 61 is running on the road surface. It is estimated that there is unevenness in.

Next, in S2, the CPU 61 presumes that the road surface is uneven in S1, that is, determines whether or not it is presumed that there is a road abnormality. When the CPU 61 determines that there is no unevenness on the road surface (S2: NO), the CPU 61 ends the temporary registration processing program shown in FIG. 7. The CPU 61 starts processing again from S1 when a predetermined time has elapsed from the time when the temporary registration processing program was terminated last time. As a result, the navigation device 6 repeatedly executes estimation of the unevenness of the road surface on which the first vehicle 4 travels while the first vehicle 4 is traveling. The temporary registration processing program may be executed by the navigation device 6 only when a specific processing such as route guidance to the destination is being executed.

Further, in S2, when the CPU 61 determines that the road surface is uneven (S2: YES), the CPU 61 accesses the probe information DB 22 of the server device 3 and temporarily registers the abnormal road position (S3). In S3, the CPU 61 transmits, for example, the information (a) to (e) (see FIG. 5) such as the above-mentioned traveling link ID and the information instructing the temporary registration to the server device 3. After executing the temporary registration in S3, the CPU 61 ends the temporary registration processing program shown in FIG. 7, and when a predetermined time has elapsed from the completion, the CPU 61 starts the processing again from S1.

In S3, the CPU 61 transmits the link ID of the traveling road on which the first vehicle 4 is traveling, for example, when the unevenness of the road surface is detected, as the link ID of (a) traveling. Further, the CPU 61 transmits (b) the position coordinates of the first vehicle 4 (position information of GPS 51, etc.) at the time when it is estimated that the road surface is uneven, as the position coordinates of the abnormal road position. This position coordinate information is an example of the position information of the road abnormal position of the present application. When the CPU 61 detects the unevenness of the road surface over a long distance, for example, only the starting point at which the unevenness of the road surface is detected may be transmitted to the server device 3 as a road abnormality position and temporarily registered.

Further, the CPU 61 transmits information on the time when the first vehicle 4 has entered the link, for example, as the time when the first vehicle 4 has entered the link (c). Further, the CPU 61 transmits (d) information indicating that there is unevenness as the detection information of the sensor. Further, in the second embodiment, the CPU 61 transmits (d) information indicating that there is an obstacle, a detection value of the steering sensor, and the like as the detection information of the sensor. Further, in the third embodiment, the CPU 61 transmits (d) information indicating that the road surface μ is lowered, ABS operating time, and the like as detection information of the sensor. Further, the CPU 61 transmits (e) the serial number of the navigation device 6 as a vehicle ID for identifying the source vehicle. As the vehicle ID, other information (vehicle number, etc.) that can individually identify the vehicle can be adopted.

On the other hand, when the CPU 31 of the server device 3 receives the information instructing the temporary registration from the CPU 61 (first vehicle 4) (S11), each of the information received together with the instruction information is stored in the corresponding column (temporary registration) of the probe information DB 22. (S12). As a result, the temporary registration in the probe information DB 22 is completed. It should be noted that the server device 3 may determine whether to perform temporary registration or main registration. For example, the CPU 61 of the navigation device 6 may transmit only the information of (a) to (e) to the server device 3. Then, the CPU 31 of the server device 3 may determine whether to temporarily register or to perform main registration based on, for example, the type and model number of the sensor.

The CPU 31 executes S13 after executing S12. In S13, the CPU 31 determines whether or not there is a subsequent second vehicle 5 that is expected to travel at the temporary registration point that was provisionally registered in S12. The subsequent second vehicle 5 that is expected to travel at the temporary registration point referred to here is, for example, the second vehicle 5 traveling toward the temporary registration point on the road on which the road abnormality is detected, or the temporary vehicle 5 described later. The second vehicle 5 exists in a distance or range that may pass through the temporary registration point by detouring or the like by notifying the passage route passing through the registration point from the server device 3. For example, the navigation device 6A of the second vehicle 5 periodically transmits the position information acquired by the GPS 51, the vehicle ID, and the information (accuracy, etc.) of the second sensor 8 mounted on the second vehicle 5 to the server device 3. The CPU 31 of the server device 3 determines the second vehicle 5 existing in a range of a predetermined distance about the temporary registration point based on the position information received from the second vehicle 5. This predetermined distance is, for example, a distance at which the driver driving the second vehicle 5 may detour and stop at the temporary registration point, and is several km to several tens of km. Based on the information of the second sensor 8 received from the second vehicle 5, the server device 3 succeeds in S13 when the second vehicle 5 provided with the high-precision sensor and the in-vehicle camera exists as the second sensor 8. It is determined that the second vehicle 5 exists (S13: YES). As will be described later, this is when the main registration is performed by detecting the road abnormality with the high-precision second sensor 8 (registration is confirmed) and the road abnormality position is displayed based on the information of the main registration. This is because the vehicle image data captured by the second vehicle 5 is used.

When the CPU 31 determines in S13 that there is a subsequent second vehicle 5 that is expected to travel in the abnormal road position (S13: YES), the CPU 31 executes S14. In S14, the CPU 31 creates a passage route through which the subsequent second vehicle detected in S13 passes through the temporary registration point. The CPU 31 searches for a passage route passing through the temporary registration point from the current position based on the position coordinates of the temporary registration point, the current position of the subsequent second vehicle 5, and the server-side map information DB 23. This passage route is the route from the current position to the temporary registration point, the route from the current position to the current position via the temporary registration point, or the main route from the current position through the temporary registration point. It is a route to reach the main road.

The CPU 31 executes S15 after executing S14. The CPU 31 transmits the information on the passage route created in S14 to the subsequent second vehicle 5 (S15). When the CPU 31 detects a plurality of subsequent second vehicles 5 in S13, the CPU 31 may transmit the passage route information to only one of them, and the CPU 31 may transmit the passage route information to two or more of the second vehicles 5, respectively. Information on the passage route of the vehicle may be transmitted.

Further, the method of determining the subsequent second vehicle 5 is not limited to the method of using the range centered on the temporary registration point described above. For example, the server device 3 periodically acquires information on the guidance route being guided from the second vehicle 5, and when a temporary registration point exists on the guidance route, the second vehicle 5 is used as the subsequent second vehicle. It may be determined as 5. Further, the server device 3 obtains the vehicle ID of the second vehicle 5 (serial number of the navigation device 6 and the like) and the information of the second sensor 8 included in the second vehicle 5 based on the information acquired from the second vehicle 5. The second vehicle 5 provided with a high-precision sensor and an in-vehicle camera as the second sensor 8 may be detected as the second sensor 8 from the vehicle existing in the range centered on the temporary registration point by accumulating the association in the DB. Alternatively, the navigation device 6A (CPU61A) of the second vehicle 5 may execute the process of acquiring the information of the temporary registration point. For example, the navigation device 6A may inquire of the server device 3 about the temporary registration points existing around the current position of the second vehicle 5 and the guidance route and guide the driver when starting the guidance of the guidance route. ..

Subsequently, the navigation device 6A of the second vehicle 5 included in the report creation support system 1 having the above configuration and the main registration processing program executed by the server device 3 will be described with reference to FIG. 7. Here, the main registration processing program is executed, for example, when the power of the navigation device 6A of the second vehicle 5 is turned on and a predetermined application program is started when the system is started, and the above-mentioned passage route information is transmitted to the server device. When received from 3, the process is started. Therefore, the second vehicle 5 that executes this main registration processing program is the subsequent second vehicle 5 detected in S13 described above. The main registration processing program is a program that notifies the driver of the passage route received from the server device 3, determines the passage of the temporary registration point, detects a road abnormality, and then executes the main registration of the road abnormality position. The program shown in the flowchart in FIG. 7 below is stored in, for example, a RAM 62, a ROM 63, or the like included in the navigation device 6A, and is executed by the CPU 61A.

Further, this registration processing program is executed, for example, by starting a predetermined application program when the system is started in the server device 3, and information on the abnormal road position (temporary registration point) is executed from the navigation device 6A of the second vehicle 5. Then, the process is started when the vehicle image data of the abnormal road position is received. The main registration processing program is a program for main registration of the received information in the report DB 24. The program shown in the flowchart in FIG. 7 below is included in the report creation support processing program stored in the RAM 32 and ROM 33 included in the server device 3, and is executed by the CPU 31.

First, in S21 shown in FIG. 7, when the CPU 61A of the navigation device 6A receives the information on the passage route from the server device 3, the CPU 61A notifies the driver of the received passage route (S22). FIG. 8 shows an example of a screen that guides the passage route. For example, as shown in FIG. 8, the CPU 61A provides a navigation device with a guidance button 92 for guiding and a cancel button 93 together with a message 91 stating that "there is a temporary registration point for which the unevenness of the road surface is desired to be confirmed". It is displayed on the liquid crystal display 46 of 6. For example, when the operation unit 45 accepts the operation of selecting the guide button 92, the CPU 61A displays the passage route received from the server device 3 in S21 on the liquid crystal display 46. As a result, the second vehicle 5 can be guided to the temporary registration point. Further, when the operation unit 45 accepts the operation of selecting the cancel button 93, the CPU 61A erases the display of the message 91 and returns to the original display screen.

The method of notifying the driver of the abnormal road position is not limited to the above method. For example, the CPU 61A acquires information on the temporary registration points existing around the current position of the second vehicle 5 from the server device 3, displays the acquired temporary registration points on the liquid crystal display 46, and guides the temporary registration points to the driver. You may. As a result, the driver can check the display on the liquid crystal display 46, determine the temporary registration point to stop by, and pass through.

Further, the CPU 61A may present incentive information that makes the driver want to stop by the temporary registration point. This incentive information is, for example, information that motivates the driver to pass through the temporary registration point by presenting useful information for the driver. As an incentive service, for example, a vendor of navigation device 6A and other companies (car dealers and insurance companies) cooperate with each other to establish a system in which points can be accumulated by passing through a temporary registration point. You can adopt services that reduce vehicle inspection costs and vehicle insurance costs. For example, as shown in FIG. 8, the CPU 61 displays a point information button 94 for displaying point information on the liquid crystal display 46. When the CPU 61 accepts the operation of selecting the point information button 94 to the operation unit 45, the point information added by passing through the temporary registration point this time, the accumulated point information up to now, the vehicle inspection cost and the insurance cost Display information such as the number of points that can receive the discount system. As a result, the driver can be motivated to pass through the temporary registration point.

The incentive service is not limited to the above-mentioned discount system for vehicle inspection costs. For example, by collecting the highly accurate information of the second sensor 8, the probe information DB 22 with higher reliability can be generated. As a result, by using this probe information DB 22, road repair and the like can be performed quickly and accurately. Therefore, providing the information detected by the second sensor 8 after passing through the temporary registration point to the server device 3 (road repair company) also contributes to society. Therefore, for example, the number of times the temporary registration point is passed and the main registration is executed may be ranked for each region, and the ranking may be displayed as incentive information. This ranking is the ranking of drivers who are contributing to road repair in the area. As a result, the driver can be motivated to pass through the temporary registration point for the purpose of contributing to society.

The CPU 61A executes S23 after starting notification (guidance) of the passage route in S22 of FIG. 7. The CPU 61A determines whether or not the second vehicle 5 has passed the temporary registration point of the passage route notified in S22. The CPU 61A repeatedly executes the determination process of S23 until it passes through the temporary registration point (S23: NO). As a result, the CPU 61A repeatedly executes the determination process of S23 until the second vehicle 5 passes the notified temporary registration point. The CPU 61A may end the determination process of S23 based on a predetermined condition. For example, the CPU 61A may end the determination process of S23 and end the process shown in FIG. 7 when the distance between the notified temporary registration point and the current position of the second vehicle 5 becomes a predetermined distance or more. In this case, since there is a high possibility that the driver's feelings will change and the second vehicle 5 will not pass through the temporary registration point, the passage route and the temporary registration point displayed on the liquid crystal display 46 may be automatically deleted. Alternatively, the CPU 61A may end the determination process of S23 when the operation unit 45 receives an operation of canceling the guidance of the passing route from the driver.

When the CPU 61A executes S23 to determine the passage of the temporary registration point, the CPU 61A performs another temporary registration until it passes through the temporary registration point or ends the process of S23 under the above-mentioned predetermined conditions. It is not necessary to execute the notification of the point. That is, it is not necessary to present another temporary registration point to the driver heading for the temporary registration point. Further, the CPU 61A accumulates information on another passage route (temporary registration point) received from the server device 3 until the second vehicle 5 passes through the temporary registration point, and at the timing of passing, another passage route is used. You may notify.

Further, in the third embodiment (decrease in road surface μ) shown in FIG. 4, it is not preferable to guide a general vehicle such as a luxury car because the guidance to the temporary registration point where the ABS is operated is executed. Therefore, in the third embodiment, it is preferable that the repair vehicle and the patrol vehicle to be repaired are targeted as the second vehicle 5 to be guided. Further, since the second embodiment (road obstacle) is provisionally registered based on sudden steering or sudden deceleration, it is uncertain whether there is actually an obstacle. Therefore, for example, the second vehicle 5 to be guided may be changed according to the degree and number of times of sudden steering and sudden deceleration (high probability that there is an obstacle registered temporarily).

Further, the server device 3 does not have to guide the second vehicle 5 to the temporary registration point. For example, the navigation device 6A may periodically detect the road abnormality while the second vehicle 5 is traveling, and may transmit the road abnormality information to the server device 3 based on the detection. Then, when the server device 3 receives the road abnormality information from the second vehicle 5 (second sensor 8), the server device 3 may execute the main registration. In this case, the server device 3 may execute the main registration even at a point where there is no provisional registration.

In S23 of FIG. 7, when the CPU 61A determines that the second vehicle 5 has passed the temporary registration point (S23: YES), the CPU 61A executes S24. In S24, the CPU 61A estimates the road abnormality based on the detection information detected by the second sensor 8. For example, in the first embodiment, the CPU 61A estimates the unevenness of the road surface while the second vehicle 5 is traveling, based on the fluctuation of the acceleration detected by the vertical acceleration sensor (second sensor 8). For example, the CPU 61A acquires the detection information of the vertical acceleration sensor (second sensor 8) from the time when the second vehicle 5 enters the traveling link including the temporary registration point, and the vehicle captured by the in-vehicle camera (second sensor 8). Start acquiring image data. After passing through the temporary registration point, the CPU 61A estimates the unevenness of the road surface based on the detection information of the vertical acceleration sensor acquired while passing through the temporary registration point. The CPU 61A may estimate the unevenness of the road surface based on the detection information acquired before and after the temporary registration point. That is, the CPU 61A may detect the road abnormality by the second sensor 8 within a predetermined range including the temporary registration point.

The CPU 61A executes S25 and then S25. The CPU 61A determines the estimation result of S24 in S25. The CPU 61A determines whether or not it is estimated that the road surface is uneven, that is, that there is a road abnormality. When the CPU 61A determines that there is no unevenness on the road surface (S25: NO), the CPU 61A ends the process shown in FIG. 7. The CPU 61 finishes the guidance of the passing route and restores the display of the liquid crystal display 46. In this case, since the road abnormality could not be detected by the guided second vehicle 5, the server device 3 may perform a process of guiding another second vehicle 5 to the temporary registration point.

Further, in S25, when the CPU 61A determines that the road surface is uneven (S25: YES), the CPU 61A accesses the probe information DB 22 of the server device 3 and performs the main registration of the abnormal road position (S26). In S26, the CPU 61A transmits the information of the main registration (information of (a) to (d)) shown in FIG. 5 and the information instructing the main registration to the server device 3 as in the provisional registration. Further, the CPU 61A transmits the vehicle-mounted image data of the road abnormality position captured by the vehicle-mounted camera when the road abnormality is detected to the server device 3. The time when the road abnormality referred to here is detected is, for example, the timing when the road abnormality estimated in S24 is detected. When the CPU 61A executes S26, the CPU 61A ends the process shown in FIG. 7.

On the other hand, when the CPU 31 of the server device 3 receives the information instructing the main registration from the CPU 61A (second vehicle 5) (S31), each of the information received together with the instruction information is displayed in the column corresponding to the main registration of the probe information DB 22. It is stored in (S32). Further, the CPU 31 stores the vehicle image data received from the CPU 61A, for example, the image data obtained by capturing the road abnormality position detected by the second sensor 8 in the probe information DB 22 in association with the information of the road abnormality position to be registered. .. As a result, the position coordinates of the abnormal road position and the vehicle image data are associated with each other and stored in the probe information DB 22, and the main registration in the probe information DB 22 is completed. When the server device 3 executes S32, the server device 3 ends the process shown in FIG. 7.

Further, as shown in FIG. 5, the CPU 61 transmits, for example, information indicating that there is unevenness, a detection value of the vertical acceleration sensor, and the like as the detection information of the (d) sensor of the main registration. Further, in the second embodiment, the CPU 61 extracts, for example, information indicating that there is an obstacle, image data captured by an in-vehicle camera, and image data after image processing as the detection information of the sensor (d). Send information about feature points. Further, in the third embodiment, the CPU 61 transmits (d) information indicating that the road surface μ is lowered, image data of an in-vehicle camera, and the like as detection information of the sensor.

In this way, in the report creation support system 1 of the present embodiment, the high-precision second sensor 8 is sent to the temporary registration point where the temporary registration is executed in the first vehicle 4 equipped with the low-precision first sensor 7. The second vehicle 5 to be mounted is guided. As a result, the second sensor 8 (second vehicle 5), which has a small total number, can be efficiently guided to the abnormal road position, and the highly reliable probe information DB 22 can be quickly constructed.

The server device 3 may determine the coincidence between the coordinate position of the temporary registration point and the coordinate position of the main registration. Then, the server device 3 may cancel the main registration when the coordinate positions do not match. Alternatively, the server device 3 may perform the main registration if there is a deviation in the coordinate position but the deviation is within a predetermined range. This predetermined range is an acceptable range as an error in the coordinate position. For example, it is an error range of the position accuracy of the GPS 51, or a range in which an obstacle may move in the second embodiment.

Subsequently, the communication terminal 10 included in the report creation support system 1 having the above configuration and the report creation processing program executed by the server device 3 will be described with reference to FIG. Here, the report creation processing program is executed, for example, by starting a predetermined application program after the system of the communication terminal 10 is started. The report creation processing program is a program that receives the input information of the worker 9 and requests the server device 3 to create a report in which the contents corresponding to the road abnormality are input. The program shown in the flowchart in FIG. 9 below is stored in, for example, the memory 72 included in the communication terminal 10 and executed by the CPU 71.

Further, the report creation processing program is executed, for example, by starting a predetermined application program at the start of the system in the server device 3, and the processing starts when the information requesting the creation of the report is received from the communication terminal 10. Will be done. The report creation processing program is a program that creates a report based on input information and the like received from the communication terminal 10. The program shown in the flowchart in FIG. 9 below is included in the report creation support processing program stored in the RAM 32 and ROM 33 included in the server device 3, and is executed by the CPU 31.

First, in S41 shown in FIG. 9, the CPU 71 of the communication terminal 10 transmits information requesting the creation of a report to the server device 3. The CPU 71 transmits, for example, information requesting the creation of a report to the server device 3 at the timing when the application program for creating the report is started or at the timing when a predetermined operation is performed in the application program. Further, the CPU 71 transmits the position information of the current position of the communication terminal 10 to the server device 3 together with the information of the creation request (S41). The CPU 71 detects the current position based on the GPS information of the GPS 81, and transmits the position information of the current position to the server device 3.

For example, the worker 9 rides on the inspection vehicle to the registered road abnormality position and takes measures against the road abnormality. The worker 9 takes measures such as checking and repairing the unevenness of the road surface and collecting obstacles. After taking action, the worker 9 operates the communication terminal 10 to create a report. At this time, the application program is started, and the above-mentioned creation request information and location information are transmitted from the communication terminal 10 to the server device 3.

On the other hand, when the CPU 31 of the server device 3 receives the information of the report creation request and the location information from the communication terminal 10 in S61 (S61), it executes S62. In S62, the CPU 31 acquires the map information around the current position of the communication terminal 10 from the server-side map information DB 23 based on the position information received from the communication terminal 10. The CPU 31 acquires the road abnormality position existing on the map of the acquired map information from the probe information DB 22. The CPU 31 acquires the road abnormality position existing on the map based on, for example, the longitude and latitude information of the map information and the "position coordinates of the road abnormality position" in the main registration of the probe information DB 22.

Further, the CPU 31 acquires the vehicle image data associated with the abnormal road position to be acquired from the probe information DB 22. This vehicle image data is image data captured by the second sensor 8 (vehicle-mounted camera) of the second vehicle 5, and is image data obtained by capturing the unevenness of the road surface or the like. The CPU 31 generates display data in which a mark indicating an abnormal road position and vehicle image data are arranged on a map indicated by map information acquired from the server-side map information DB 23. The CPU 31 transmits the display data generated in S62 to the communication terminal 10 (S63).

The CPU 71 of the communication terminal 10 executes S42 and then S42. In S42, the CPU 71 displays the display data received from the server device 3 on the display 78. FIG. 10 shows an example of a display screen displayed on the display 78 of the communication terminal 10. As shown in FIG. 10, the CPU 71 superimposes a pin 102 indicating an abnormal road position on the map of the map information 101 and displays it on the display 78 based on the display data. Further, the CPU 71 displays a balloon 103 for each pin 102. The CPU 71 displays in the balloon 103 the type of road abnormality occurring at the pin 102 (the unevenness of the road surface in the illustrated example), the position coordinates of the road abnormality position, and the vehicle image data 104 that captures the road abnormality position. .. These information are the information acquired from the probe information DB 22 by the server device 3 in S62 described above.

Further, as shown in FIG. 10, the CPU 71 superimposes the current position mark 105 indicating the current position of the communication terminal 10 on the map information 101 based on the GPS information of the GPS 81. As a result, the worker 9 who operates the communication terminal 10 can confirm his / her current position and can easily confirm the road abnormality position (pin 102) where the countermeasure has been taken. The server device 3 may display only the pin 102 at the abnormal road position closest to the current position on the communication terminal 10 based on the current position of the communication terminal 10. Further, when the communication terminal 10 accepts an operation of changing the position of the map displayed on the display 78, the changed position may be transmitted to the server device 3. Then, the server device 3 may generate display data centered on the changed position based on the received changed position and transmit the display data to the communication terminal 10. As a result, the communication terminal 10 can change the information of the map to be displayed and the pin 102 according to the operation of the worker 9. For example, the worker 9 can change the display position of the map on the display 78 and confirm the abnormal road position at the destination before moving from the company to the abnormal road position on the inspection vehicle.

The CPU 71 executes S43 and then S43. In S43, the CPU 71 determines whether or not the selection of any one of the displayed pins 102 has been accepted. For example, the worker 9 looks at the display 78, confirms the positions of the current position mark 105 and the pin 102, and confirms the abnormal road position that he / she has dealt with. The worker 9 selects the pin 102 of the road abnormality position that has been dealt with in order to prepare the report. The worker 9 selects the pin 102 by touching the touch panel of the input operation unit 80 or the like.

The CPU 71 repeatedly executes the determination process of S43 in S43 until the selection of the pin 102 is accepted (S43: NO). Further, when the CPU 71 determines that the selection of the pin 102 has been accepted (S43: YES), the CPU 71 transmits the information of the accepted pin 102 to the server device 3 (S44). As a result, the server device 3 can accept the selection of the abnormal road position for creating the report. The method of accepting the selection of the abnormal road position described above is an example. For example, the server device 3 may display not only the abnormal road position of the main registration but also the temporary registration point on the communication terminal 10 and accept the report of the temporary registration point.

On the other hand, the CPU 31 of the server device 3 executes S64 after executing S63. The CPU 31 receives the information on the pin 102 from the communication terminal 10, that is, receives the information on the pin 102 selected by the worker 9 (S64), and executes S65. In S65, the CPU 31 transmits the display data of the setting screen that receives the input information to be input to the report to the communication terminal 10.

The CPU 71 of the communication terminal 10 executes S44 and then S45. When the CPU 71 receives the display data of the setting screen, the CPU 71 displays the setting screen on the display 78 based on the display data (S45). After executing S45, the CPU 71 determines whether or not the input to the setting screen is completed (S46).

FIG. 11 shows an example of a setting screen displayed on the display 78 of the communication terminal 10. As shown in FIG. 11, the CPU 71 has a selection display field 110 for displaying selected input information, a selection button 111 for selecting information to be displayed in the selection display field 110, and a remark that character information can be input as input information. The column 112, the image attachment button 113, and the send button 114 are displayed on the display 78. In the present embodiment, the items to be displayed as the selection display field 110 include, for example, (a) inspection date, (b) creator, (c) abnormal species, (d) route, (e) position coordinates, and (f). The status is included.

The CPU 71 displays the selection button 111 next to the selection display field 110 of (a), (b), (c), and (f) described above, and accepts an operation on the selection button 111. The worker 9 operates the touch panel or the hard button of the input operation unit 80 to select an arbitrary selection button 111. For example, when the CPU 71 receives an operation on the (a) inspection date selection button 111, the CPU 71 displays a calendar on the display 78 and accepts a date selection from the displayed calendar. The CPU 71 inputs the selected date into the (a) inspection date selection display field 110. As a result, the worker 9 can input the date when the countermeasure for the abnormal road position is taken, that is, the date to be reported in the report as the inspection date.

Further, for example, when the CPU 71 receives an operation on the creator's selection button 111, the CPU 71 displays the name of the worker 9 in a pull-down menu format, and accepts the selection of the creator's name from the displayed names. The CPU 71 inputs the name of the selected creator into (b) the selection display field 110 of the creator. As a result, the worker 9 can input the creator of the report. The data of the name of the worker 9 may be the data stored in the memory 72 of the communication terminal 10 or the data acquired from the server device 3.

Further, for example, when the CPU 71 accepts an operation on the (c) abnormality type selection button 111, the road abnormality type is displayed in a pull-down menu format, and the selection of the road abnormality type to be reported is accepted from the displayed types. .. The CPU 71 inputs the selected type to (c) the selection display field 110 of the abnormal type. As a result, the worker 9 can input the type of road abnormality to be reported in the report. The types of road abnormalities include, for example, unevenness of the road surface shown in FIG. 4, obstacles on the road, and reduction of the road surface μ. Alternatively, the type of road abnormality input on the setting screen may be information that further subdivides the type of road abnormality detected by the first vehicle 4 and the second vehicle 5 shown in FIG. For example, more detailed types of road abnormalities such as potholes of X cm or more, steps of manholes, and cracks in roads having a width of X1 cm to X2 cm may be used. As a result, the worker 9 can confirm and input more detailed information about the type of road abnormality at the site of the road abnormality position.

Further, in the (d) route and (e) position coordinates, for example, data based on the position coordinates of the pin 102 selected in S43, that is, the position coordinates of the road abnormality position reported this time is displayed. The display items of the (d) route and (e) position coordinates may be set in advance in the display data by the server device 3, and the display data set in S65 may be transmitted to the communication terminal 10. Then, the CPU 71 may display (d) and (e) based on the display data received from the server device 3. The server device 3 acquires the position coordinates of the abnormal road position selected in S43 from the probe information DB 22, and displays the national road in (d) based on the acquired position coordinate information and the information of the server side map information DB 23. It is possible to obtain information on the name and whether the road is up or down. Further, the information of the position coordinates (e) is, for example, the position coordinates of the road abnormality position (selected in S43) of the probe information DB 22. The CPU 71 may search the map information included in the communication terminal 10 based on the information of the pin 102 selected in S43, and display the information of (d) and (e).

Further, for example, when the CPU 71 receives an operation on the status selection button 111 (f), the CPU 71 displays the status type in a pull-down menu format, and accepts the selection of the status type to be reported from the displayed types. The CPU 71 inputs the selected type into the (f) status selection display field 110. The status is, for example, information indicating the result of the action. Items to be displayed in (f) include, for example, "start of countermeasures" indicating that countermeasures for road abnormalities have been started, "completion of countermeasures" indicating that countermeasures such as repairs have been completed, and observing the progress of road abnormalities. Items such as "follow-up required" can be adopted. By selecting the item (f), the worker 9 can input the result of the action into the report.

The input method using the selection display field 110 and the selection button 111 described above is an example. For example, the CPU 71 may receive a character input from the worker 9 by the input operation unit 80 and input the received character into the selection display field 110. Alternatively, the CPU 71 may perform a combination process of the above-mentioned automatic input, selective input, and manual input. For example, the CPU 71 may automatically input only the national highway name in the item (d) of the route, and receive up / down information, lane position information, and the like from the worker 9.

Further, the CPU 71 accepts the input to the remarks column 112 based on the operation input of the input operation unit 80. The remarks column 112 is, for example, a column for inputting information to be reported in the report, items to be handed over, special notes, and the like. The worker 9 can input characters in the remarks column 112 by operating the input operation unit 80 and selecting the remarks column 112. In the example shown in FIG. 11, "Although the unevenness of the road surface was confirmed, it was necessary to follow up because there was a regular inspection in the near future (2019/06/11)" is input. As described above, in the report creation support system 1 of the present embodiment, not only the completion of the countermeasure but also the follow-up observation and the progress can be reported in the report.

Further, when the CPU 71 receives an operation on the image attachment button 113 based on the operation input of the input operation unit 80, the CPU 71 displays a screen for selecting image data to be attached to the report. This image data is, for example, image data obtained by capturing an abnormal road position with the camera 79 of the communication terminal 10 (hereinafter, may be referred to as coping image data). After dealing with the road abnormality, the worker 9 takes a picture of the road condition after the action with the camera 79, and selects the action image data captured on the screen after selecting the image attachment button 113 to deal with the report. Image data can be attached.

Further, when the CPU 71 receives an operation for the transmission button 114 based on the operation input of the input operation unit 80, the CPU 71 transmits the input information received on the setting screen shown in FIG. 11 to the server device 3. More specifically, the CPU 71 executes S46 after executing S45 in FIG. In S46, it is determined whether or not the input to the setting screen is completed. The CPU 71 makes a negative determination (S46: NO) in S46 and repeatedly executes the determination in S46 until the operation input to the transmission button 114 is received. Further, when the CPU 71 receives the operation input for the transmission button 114 (S46: YES), the CPU 71 transmits the input information received on the setting screen to the server device 3 (S47). The input information referred to here is the information in the selection display field 110 shown in FIG. 11, the information in the remarks field 112, and the coping image data selected by the image attachment button 113.

The CPU 31 of the server device 3 executes S66 and then S66. When the CPU 31 receives the input information of the setting screen from the communication terminal 10 (S66), the CPU 31 creates a report based on the input information (S67). FIG. 12 shows an example of the report. As shown in FIG. 12, the CPU 31 inputs, for example, (a) the inspection date and (b) the input information 122 of the creator in the upper right corner of the report 121. Further, the CPU 31 inputs (c) anomalous species, (d) a route, (e) position coordinates, and (f) status input information 123 below the input information 122 and at the left end of the report 121. The (d) route and (e) position coordinate position information 123A included in the input information 123 are examples of the position information of the road abnormal position in the present application. The position information 123A of the (d) route and (e) position coordinates may be automatically input by the server device 3 using the probe information DB 22 and the server side map information DB 23, that is, the information on the server device 3 side. When the change is accepted on the setting screen (see FIG. 11) displayed on the communication terminal 10, the changed input information may be used. Therefore, the CPU 31 of the present embodiment receives the input information 122, 123 ((a), (b), (c), (f)) received on the setting screen shown in FIG. 11, and the position information 123A (of) the abnormal road position. A report 121 in which (d) and (e)) are input is created.

Further, the CPU 31 inputs the coping image data selected by the image attachment button 113 on the setting screen into the image attachment field 124 in the center of the report 121. The CPU 31 may input the vehicle image data 104 (see FIG. 10) in which the second vehicle 5 has captured the abnormal road position in the image attachment field 124. Further, the CPU 31 inputs the input information 125 received in the remarks column 112 of the setting screen to the lower part of the report 121. As a result, the server device 3 can automatically create a report 121 related to the abnormal road position dealt with by the worker 9. The configuration of report 121 shown in FIG. 11 is an example. For example, the CPU 31 does not have to provide the image attachment column 124 in the report 121. Alternatively, the CPU 31 may input map information around the abnormal road position into the report 121.

After creating the report 121 in S67, the CPU 31 transmits the created report 121 to the communication terminal 10 (S68). After executing S47, the CPU 71 of the communication terminal 10 displays the report 121 received from the server device 3 on the display 78 (S48). After displaying the report 121, the CPU 71 accepts confirmation of whether or not the content of the report 121 is correct, for example, on the display screen of the display 78 displaying the report 121 (S49).

The CPU 71 repeatedly executes the determination process of S49 until the operation input indicating that the content is correct is received via the input operation unit 80 (S49: NO). When the CPU 71 determines that the operation input indicating that the content is correct has been accepted (S49: YES), the CPU 71 transmits information indicating that the confirmation has been completed to the server device 3 (S50). When the CPU 71 executes S50, the CPU 71 ends the process shown in FIG.

On the other hand, the CPU 31 of the server device 3 executes S68 and then S69. When the CPU 31 receives the information that the confirmation is completed from the communication terminal 10 (S69), the CPU 31 executes S70. The CPU 31 associates the report 121 created in S67 with the map information of the server-side map information DB 23 and stores it in the report DB 24. For example, the CPU 31 stores the (e) position coordinates input in the report 121 and the map information of the server-side map information DB 23 in association with each other in the report DB 24. As a result, the report 121 can be displayed later in association with the map information.

The communication terminal 10 may accept the change of the report 121 in the confirmation process of the report 121 of S48 and S49. The communication terminal 10 may transmit the received change information to the server device 3 and request the server device 3 to create the report 121 after the change. Further, the server device 3 does not have to request the communication terminal 10 to confirm the created report 121. The server device 3 may execute S70 after creating the report 121 in S67 and store it in the report DB 24.

Further, the data structure of the report DB 24 is not particularly limited. For example, the server device 3 may assign an identification number in the order of occurrence of road abnormalities or the order in which the report is created, and store the report 121 in the report DB 24. Further, the server device 3 may store the report 121 in the report DB 24 without associating it with the map information of the server-side map information DB 23.

As described in detail above, the server device 3 of the report creation support system 1 according to the present embodiment receives the position information 123A of the road abnormality position where the road abnormality is detected from the first vehicle 4 and the second vehicle 5. (S11, S31). The server device 3 displays the abnormal road position on the map based on the received position information 123A (S62, S63). The server device 3 accepts the selection of the abnormal road position for creating the report 121 from the displayed abnormal road positions (S64). The server device 3 receives the input information 122, 123, 125 and the coping image data to be input to the received road abnormality position report 121 (S65, S66). The server device 3 creates a report 121 in which the received input information 122, 123, 125, etc. and the position information 123A of the abnormal road position are input (S67).

According to the report creation support system 1 having the above configuration, the position information 123A of the road abnormality position where the road abnormality is detected is received from the first vehicle 4 and the second vehicle 5, and the road abnormality position is displayed on the map. The worker 9 who repairs the road selects the abnormal road position to be inspected or repaired from the abnormal road position displayed on the map, and inputs the inspection result or the repaired result as input information 122, 123, 125 or countermeasures. Input as image data. The report creation support system 1 creates a report 121 in which the received input information 122, 123, 125, etc. and the position information 123A are input. As a result, since the road abnormality is detected by the first vehicle 4 and the second vehicle 5 traveling on the road, only the position information 123A in which the abnormality has occurred can be collected. Unlike the conventional technology, it is not necessary to visually check each of a plurality of vehicle image data in which the road is continuously imaged one by one later to find an abnormal part. That is, the worker 9 and the like do not need to scrutinize the data such as searching for abnormal data from the collected data. In addition, the input information 122, 123, 125 and the countermeasure image data inspected by the worker 9 can be input to the report 121, and the current state of the abnormal road position and the state after repair can be automatically created as the report 121. .. Therefore, the work load related to the preparation of the report 121 can be reduced. Further, unlike the conventional technology, since the data is not collected including the section without abnormality, it is possible to reduce the amount of data to be accumulated (the amount of data such as position information and vehicle image data).

Further, in the report creation support system 1 according to the present embodiment, the point where the first sensor 7 provided in the first vehicle 4 detects the unevenness of the road surface is the position where the road condition is abnormal (temporary registration). (Point) is provisionally registered in the probe information DB 22 (S12). The report creation support system 1 detects an abnormality at the temporary registration point by the second sensor 8 of the second vehicle 5 equipped with the second sensor 8 with high accuracy, and the road is temporarily registered in the probe information DB 22. The main registration of the abnormal position is performed (S32).

According to this, the points where the unevenness of the road surface is detected by the low-precision first sensor 7 of the first vehicle 4 are provisionally registered. That is, the abnormal road position detected by the low-precision sensor is treated as a provisional registration with low reliability. On the other hand, when an abnormality of the temporarily registered temporary registration point is detected by the high-precision second sensor 8 of the second vehicle 5, the temporary registration point is officially registered. That is, the road abnormality position detected by both the first and second sensors 7 and 8 is officially registered as more reliable information. As a result, the road condition information detected by the sensor can be appropriately registered according to the accuracy of the sensor. More accurate information can be utilized in the preparation process of report 121. In addition, highly accurate information can be provided to ministries and agencies that manage roads, such as the Ministry of Land, Infrastructure, Transport and Tourism. It should be noted that detecting an abnormality at a temporarily registered temporary registration point is not limited to the case where an abnormality is detected by the second sensor 8 at a point having the same position coordinates as the temporary registration point, but also within a certain range from the temporary registration point ( This includes the case where an abnormality is detected by the second sensor 8 in the error range of the GPS 51, etc.).

It should be noted that the present invention is not limited to each of the above-described embodiments, and it goes without saying that various improvements and modifications can be made without departing from the gist of the present invention.
For example, in each of the above embodiments, the report creation support system 1 provisionally registers the road abnormality information received from the first vehicle 4, and the road abnormality information received from the second vehicle 5 is fully registered. Then, the server device 3 created the report 121 regarding the registered road abnormal position. However, the server device 3 may prepare a report 121 regarding the provisionally registered road abnormality position.
Further, the server device 3 may perform a process of displaying all the abnormal road positions on the map without distinguishing the information of the abnormal road positions received from the vehicle, and may accept the preparation of the report 121.

Further, the server device 3 does not have to display the vehicle image data captured by the second vehicle 5 on the communication terminal 10 in association with the abnormal road position. For example, the server device 3 may display only the pin 102 (the abnormal road position of the present application) on the map of the display 78. Further, the server device 3 collects information on the abnormal road position from the first vehicle 4 and the second vehicle 5 traveling on the road, and displays the abnormal road position detected by each vehicle as a pin 102 on the map of the display 78. You may.
Further, the server device 3 does not have to guide the second vehicle 5 to the temporary registration point.
Further, the server device 3 does not have to create a passage route through which the second vehicle 5 passes through the temporary registration point.

Further, in each of the above embodiments, the navigation devices 6 and 6A provisionally register and the main registration of the information indicating the road abnormality, but other devices may execute the information. For example, the navigation devices 6 and 6A may transmit the types (accuracy) of the first and second sensors 7 and 8 and the estimation result to the server device 3. Then, the server device 3 may determine whether to perform provisional registration or main registration based on the contents of the data received from the navigation devices 6 and 6A, and execute each registration. That is, the server device 3 may execute the determination of temporary registration or main registration.
Alternatively, the navigation device 6 of the first vehicle 4 may execute only the process of periodically transmitting the detection information (wheel speed value, etc.) of the first sensor 7 to the server device 3. Then, the server device 3 may execute the estimation based on the detection information received from the first vehicle 4 and determine the unevenness of the road surface or the like. That is, the server device 3 may execute the estimation of the road abnormality. Further, the server device 3 and the navigation devices 6 and 6A may execute a part of the processing of estimation, provisional registration, and main registration in cooperation with each other.

Further, although the server device 3 has executed the provision of the data for which the main registration has been completed after the provisional registration, the provision of the data for the provisional registration and the provision of the data for the main registration without the provisional registration may be executed.
The types of the first and second sensors 7 and 8 described above are examples. For example, in the second embodiment, the first sensor 7 may be a sensor capable of detecting only one of sudden steering and sudden deceleration.
Further, instead of the navigation devices 6 and 6A, it is also possible to configure the report creation support system 1 with another device having a function of provisional registration and main registration. For example, in-vehicle devices other than the navigation devices 6 and 6A, mobile phones, smartphones, tablet terminals, personal computers and the like are possible.

Further, although the embodiment in which the report preparation support system according to the present invention is embodied has been described above, the report preparation support system can also have the following configurations, and in that case, the following effects are obtained. ..

For example, the first configuration is as follows.
Based on the receiving means (31) that receives the position information (123A) of the road abnormality position where the road abnormality that is the road abnormality is detected from the vehicle (4,5) and the position information received by the receiving means. The display means (31) for displaying the road abnormal position (102) on the map and the road abnormal position displayed on the map by the display means accept the road abnormal position for which the report (121) is created. The first reception means (31) and the input information (122, 123, 125, 124) to be input to the report of the road abnormality position received by the first reception means, which are related to the coping with the road abnormality. A report for creating the report in which the second receiving means (31) for receiving the input information, the input information received by the second receiving means, and the position information (123A) of the abnormal road position are input. A report preparation support system (1) including a preparation means (31).
According to the report creation support system having the above configuration, the position information of the road abnormality position where the road abnormality is detected is received from the vehicle, and the road abnormality position is displayed on the map. A worker who repairs a road confirms the abnormal position of the road to be inspected or repaired from the abnormal position of the road displayed on the map, and inputs the inspection result or the repair result as input information. The report creation support system creates a report in which the received input information and location information are input. As a result, since the road abnormality is detected by the vehicle traveling on the road, only the position information where the abnormality has occurred can be collected. Therefore, a user such as a worker does not need to scrutinize the data such as searching for abnormal data from the collected data. In addition, input information such as inspections by workers can be input to the report, and the current state of the abnormal road position and the situation after repair can be automatically created as a report. Therefore, the work load related to the preparation of the report can be reduced. Further, unlike the conventional technique, since data is not collected including a section without abnormality, it is possible to reduce the amount of data to be accumulated (position information, etc.).

The second configuration is as follows.
The vehicle (5) has an imaging means (8) for capturing a road, and the receiving means (31) captures a vehicle image of a road on which the road abnormality is detected by the imaging means in addition to the position information. Upon receiving the data (104), the display means (31) displays the vehicle image data received by the receiving means on a map in association with the road abnormality position (FIG. 10).
According to the report creation support system having the above configuration, since only the road on which the road abnormality is detected is imaged, the amount of accumulated vehicle image data can be reduced. Further, by displaying the captured vehicle image data on the map, the worker can easily visually confirm the abnormal road position and the current state of the abnormal road position.

The third configuration is as follows.
Based on the detection of the road abnormality by the first vehicle (4), the second vehicle (5) provided with the imaging means passes through the road abnormality position where the road abnormality is detected by the first vehicle. The second vehicle includes a guiding means (31) for guiding the vehicle, and the second vehicle images the road on which the road abnormality is detected by the first vehicle with the imaging means based on the guidance by the guiding means.
Vehicles traveling on the road have different equipment. Some vehicles are not equipped with a camera, but are equipped with a detection means for detecting a road abnormality such as a vehicle speed sensor. Therefore, when a road abnormality is detected in the first vehicle which does not have the imaging means, or when a road abnormality is detected in the first vehicle which has the imaging means but fails to capture the image, the second vehicle equipped with the imaging means. To the abnormal position of the road. As a result, it is possible to capture vehicle image data and display it on a map for the abnormal road position detected by another vehicle.

The fourth configuration is as follows.
The guidance means (31) is created by the route creating means (31) for creating a passage route through which the second vehicle passes through the road abnormality position where the road abnormality is detected by the first vehicle, and the route creating means. It has transmission means (31, 25) for transmitting the passing route to the second vehicle.
According to the report creation support system having the above configuration, the driver of the second vehicle sets the passing route by creating a passing route passing through the abnormal road position detected by the first vehicle and transmitting it to the second vehicle. It is possible to confirm and determine whether to execute the passage of the abnormal road position, that is, whether or not to follow the guidance. Further, it is not necessary to search for a route or the like passing through the abnormal road position on the second vehicle side, and it is possible to reduce the processing load of the device of the second vehicle and the load related to the operation of the driver.

The fifth configuration is as follows.
In addition to the input information, the second receiving means (31, 113) receives the coping image data (124) related to coping with the road abnormality, and the report creating means (31) is used by the second receiving means. The received input information (122, 123, 125), the corresponding image data, and the report (121) in which the position information (123A) is input are created.
According to the report creation support system having the above configuration, the worker actually moves to the abnormal road position confirmed on the map, performs countermeasures such as inspection and repair, and then takes a countermeasure image data of the road etc. Can be submitted by the second reception means. This makes it possible to automatically create a report in which countermeasure image data is input in addition to position information and input information.
