Description

The present invention relates to a report creation support system, a server device, and a computer program that support the creation of reports dealing with road abnormalities.

Conventionally, roads have been inspected by dividing them into a plurality of unit sections based on kilometer posts, and an inspection report has been created for each unit section. For example, in the inspection report creation support device disclosed in Japanese Unexamined Patent Publication No. 2018-147314, an inspection vehicle travels on a road in a unit section to be inspected, and an image of the road is captured by a digital video camera mounted on the inspection vehicle. The inspection report creation support device associates and stores each piece of road image data obtained by continuously imaging a road with a digital video camera and the imaging position (kilometer post value) of each piece of road image data.

When the inspection report creation support device receives the designation of an arbitrary unit section from the user, it reads out the data of the designated 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 there are any abnormalities such as potholes. When the user discovers a road abnormality, he or she clicks on the deformation determination icon displayed on the screen. When the deformation determination icon is clicked, the inspection report creation support device determines that the deformation has been confirmed by the user, and stores the kilometer post value and road image data in association with each other for the road on which the deformation has been confirmed. The inspection report creation support device creates an inspection report based on the stored kilometer post values and road image data.

Note that instead of the navigation devices 6 and 6A, for example, a mobile phone, a smartphone, a tablet terminal, or a personal computer may be used.

Here, the report creation support system 1 according to this embodiment constitutes a so-called probe car system. Here, the probe car system is a system that collects information using the first and second vehicles 4 and 5 as sensors. Specifically, the first and second vehicles 4 and 5 use the first and second sensors 7 and 8 to obtain information on road conditions, speed data, and the operation of various systems such as steering operation and shift position.

In particular, in this embodiment, the server device 3 detects road abnormalities (hereinafter sometimes referred to as road abnormalities) detected by the first sensor 7 of the first vehicle 4 and the second sensor 8 of the second vehicle 5, for example. When the registered information is accessed from an external terminal, the corresponding information is responded.

The server device 3 of this embodiment automatically creates a report and stores the created report in the report DB 24. Details of the report creation process will be described later.

Further, the center communication device 25 is used for communicating with an external traffic information center such as the first and second vehicles 4 and 5 and a VICS (registered trademark: Vehicle Information and Communication System) center via the communication network 11. It is a communication device. In this embodiment, the server device 3 transmits and receives probe information and the like to and from the first and second vehicles 4 and 5 via the center communication device 25. Further, the server device 3 transmits and receives report input information and the like to and from the communication terminal 10 via the center communication device 25.

Next, a schematic configuration of the navigation device 6 mounted on the first vehicle 4 will be described using FIG. 3. FIG. 3 is a block diagram showing the navigation device 6 according to this embodiment. In this embodiment, the navigation device 6 mounted on the first vehicle 4 and the navigation device 6A mounted on the second vehicle 5 have the same configuration. The difference is that the navigation device 6 of the first vehicle 4 is connected to the first sensor 7, while the navigation device 6A of the second vehicle 5 is connected to the second sensor 8. Therefore, in FIG. 3, the first sensor 7 of the first vehicle 4 is shown by a solid line, and the second sensor 8 of the second vehicle 5 is shown by a broken line. Furthermore, as will be described later, in this embodiment, image data captured by the second sensor 8 is used in the report creation process. For this reason, the second vehicle 5 is equipped with at least an on-vehicle camera as the second sensor 8. In the following explanation, the navigation device 6 of the first vehicle 4 will be mainly explained, and the explanation of the navigation device 6A of the second vehicle 5 will be omitted. Note that the navigation device 6 of the first vehicle 4 and the navigation device 6A of the second vehicle 5 may have different configurations.

It is composed of Further, the navigation device 6 is connected to a first sensor 7 (second sensor 8 in the case of the second vehicle 5) installed in the first vehicle 4 via an in-vehicle network such as CAN.

Below, each component constituting the navigation device 6 will be explained in order.
The current position detection unit 41 includes a GPS 51 or the like, and is capable of detecting the current position, direction, etc. of the vehicle. Note that the current position detection unit 41 may include a sensor other than the GPS 51, such as a vehicle speed sensor or a steering sensor, or may acquire and use the detection signal of the first sensor 7. The current position detection unit 41 may use a plurality of sensors to increase the accuracy of detecting the current position of the vehicle.

In addition, the data recording unit 43 reads out a hard disk (not shown) as an external storage device and a recording medium, a map information DB 52, a driving history DB 53, a distribution information DB 54, a predetermined program, etc. recorded on the hard disk, and stores them in the hard disk. It is equipped with a recording head (not shown) which is a driver for writing predetermined data. Note that the data recording section 43 may be configured with a flash memory, a memory card, or an optical disk such as a CD or DVD instead of a hard disk. Alternatively, the map information DB 52, travel history DB 53, and distribution information DB 54 may be stored in an external server, and the navigation device 6 may acquire necessary information from the external server through communication.

Here, the map information DB 52 is a storage means in which map information is stored divided into areas (eg, 20 km square mesh). Furthermore, the map information DB 52 is comprised of various information necessary for route searching, route guidance, and map display, including road networks. For example, it includes position data of the coordinate position of each point, link data regarding roads (links), node data regarding node points at both ends of the link, intersection data regarding each intersection, point data regarding points such as facilities, etc.

Further, the driving history DB 53 is a storage means that accumulates and stores driving information of the first vehicle 4 and information detected by the first sensor 7. Note that the travel information stored in the travel history DB 53 and the detection information of the first sensor 7 are appropriately transmitted to the server device 3 as probe information. Further, the distribution information DB 54 is a storage means in which probe information (information on road surface irregularities detected by other vehicles, etc.) distributed from the server device 3 is stored.

On the other hand, the navigation ECU (electronic control unit) 44 is an electronic control unit that controls the entire navigation device 6, and includes a CPU 61 as an arithmetic unit and a control device, and a working memory when the CPU 61 performs various arithmetic processes. In addition to the RAM 62 which stores route data etc. when a route is searched, and a control program, a temporary registration processing program (see FIG. 7), which will be described later (for navigation device 6A, main registration processing It is provided with an internal storage device such as a ROM 63 in which programs (programs), etc. are recorded, and a flash memory 64 that stores programs read from the ROM 63. In the following description, when the CPU of the navigation device 6A of the second vehicle 5 is explained separately from the CPU 61 of the navigation device 6 of the first vehicle 4, it will be referred to as the CPU 61A.

The operation unit 45 is operated when inputting a departure point as a travel start point and a destination as a travel end point, and is comprised of a plurality of operation switches (not shown) such as various keys and buttons. Then, the navigation ECU 44 performs control to execute various corresponding operations based on switch signals output by pressing each switch. Note that the operation section 45 can also be configured by a touch panel provided on the front surface of the liquid crystal display 46. Alternatively, it can be configured with a microphone and a voice recognition device.

The liquid crystal display 46 also displays map images including roads, traffic information, operation guidance, operation menus, key guidance, guidance information along the guidance route (planned route), news, weather forecast, time, email, and television. Programs, etc. are displayed. Further, in this embodiment, the liquid crystal display 46 particularly displays a route passing through the road abnormal position. Note that a HUD or HMD may be used instead of the liquid crystal display 46.

Furthermore, the speaker 47 outputs audio guidance for guiding travel along a guide route (planned travel route) and traffic information based on instructions from the navigation ECU 44 . In addition, in this embodiment, especially when guiding to a temporarily registered road abnormal position (hereinafter sometimes referred to as a temporary registration point), guidance is provided regarding the temporary registration point. For example, it outputs a voice guidance that says, "You're almost at a bumpy spot on the road."

Further, the DVD drive 48 is a drive that can read data recorded on recording media such as DVDs and CDs. Then, based on the read data, music and video are played back, the map information DB 52 is updated, etc. Incidentally, instead of the DVD drive 48, a card slot for reading and writing a memory card may be provided.

Further, the communication module 49 is a communication device for receiving traffic information, weather information, etc. transmitted from a traffic information center, such as a VICS center or other external center, and is, for example, a mobile phone or a DCM. It also includes a vehicle-to-vehicle communication device that communicates between vehicles and a road-to-vehicle communication device that communicates with a roadside device. It is also used to transmit and receive probe information and distribution information to and from the server device 3.

Here, as described above, the probe center 2 of the present embodiment aggregates detection information from the first and second sensors 7 and 8 of the plurality of first and second vehicles 4 and 5 to provide information, etc. use. However, the accuracy of sensors installed in vehicles differs from vehicle to vehicle. Therefore, the report creation support system 1 performs provisional registration of information indicating road abnormality and confirmation of registration after provisional registration (hereinafter sometimes referred to as official registration), depending on the accuracy of the sensor. In this 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 provisional registration based on the information detected by the first sensor 7 with low accuracy, and executes the main registration based on the information detected by the second sensor 8 with high accuracy. In addition, "sensor accuracy" in this application is not limited to a value that indicates the high performance of the same type of sensor, but also a value that indicates the high performance of a sensor of the same type, but also a value that indicates a certain event (road abnormality such as an uneven road surface), even if the sensor is of a different type. The degree of accuracy with which an event can be detected when used as a means of detection. Therefore, compared to the low-precision first sensor 7, the high-precision second sensor 8 can detect the road surface with higher precision when used as a means for detecting unevenness on the road surface (using a detection signal). This is a sensor that can detect the unevenness of the surface.

FIG. 4 shows the relationship between road abnormalities to be detected and sensors. In the following explanation, in order to provide a detailed explanation as appropriate depending on 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 permanent registration of information on road surface irregularities are performed as road abnormalities. Further, the second embodiment is a case where information on road obstacles is temporarily 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 temporarily registered as a road abnormality. Note that the types of road abnormalities in the present application are not limited to the above-mentioned types, and can include various phenomena that affect the use of the road, such as peeling of asphalt and cracks in the road.

As shown in FIG. 4, for example, a vehicle speed sensor can be used as the first sensor 7 for detecting the unevenness of the road surface in the first embodiment. As shown in FIG. 3, the navigation device 6 of the first vehicle 4 is connected to the first sensor 7, and receives a detection signal from the first sensor 7. The vehicle speed sensor (first sensor 7) generates a pulse according to the rotation of the drive 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 travel distance of the drive wheels by counting the pulses of the input pulse signal. The navigation ECU 44 estimates road surface irregularities based on, for example, changes in wheel speed. For example, the navigation ECU 44 calculates the magnitude of a specific frequency as the degree of vibration from the output of the vehicle speed sensor, 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 that detects the unevenness of the road surface, for example, a vertical acceleration sensor that detects acceleration in the vertical direction acting on the wheels of the second vehicle 5 can be employed. The navigation ECU 44 of the navigation device 6A of the second vehicle 5 estimates the unevenness of the road surface, for example, based on fluctuations in 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 road obstacles in the second embodiment, for example, a sensor for detecting sudden steering or sudden deceleration of the vehicle can be adopted. Specifically, as the first sensor 7 that detects sudden steering, a steering sensor that detects the rotation angle of the steering wheel from the neutral position and outputs a signal indicating the detected rotation angle (steering angle) may be adopted. can. Moreover, a vehicle speed sensor can be employed as the first sensor 7 that detects sudden deceleration. The navigation ECU 44 detects sudden steering and sudden deceleration based on signals input from a steering sensor and a vehicle speed sensor (first sensor 7). For example, when the rate of change in the steering angle per unit time is equal to or higher than the reference rate of change, the navigation ECU 44 determines that the steering is a sudden steering operation in which the steering wheel is rapidly rotated. Further, the navigation ECU 44 determines that the vehicle is in a sudden deceleration in which the brake is suddenly depressed when the rate of decrease in vehicle speed per unit time is equal to or higher than the reference rate of change. When a driver performs sudden steering or sudden deceleration, there is a high possibility that there are obstacles on the road (on the road surface) on which the driver is driving. 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 the road abnormal position where there is an obstacle on the road.

Further, as the second sensor 8 that detects obstacles on the road, for example, an on-vehicle camera can be used. The in-vehicle camera is configured with a camera using a solid-state imaging device such as a CCD, and is attached to the bumper, the back side of the rearview mirror, the door mirror, etc. of the second vehicle 5, and is configured to be able to image the surrounding environment of the second vehicle 5. The optical axis direction is set to . The number of in-vehicle cameras may be single or plural. For example, the in-vehicle camera images the surrounding environment in front of the vehicle in the traveling direction when the second vehicle 5 is traveling. Note that the on-vehicle camera may have an imaging range of the side or rear of the second vehicle 5 instead of the front of the second vehicle 5 in the traveling direction. The navigation device 6A (CPU 61A) of the second vehicle 5, for example, processes image data in front of the vehicle captured by an on-vehicle camera (second sensor 8), and determines whether an object larger than a predetermined size is on the road surface, etc. Determine whether or not. When the navigation device 6A detects an object larger than a predetermined size, the navigation device 6A estimates that 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 that detects a decrease in road surface μ in the third embodiment, for example, a sensor that detects the operation of an anti-lock brake system (ABS) may be adopted. can. The μ (friction coefficient) of a road surface decreases due to rain, snow, ice, etc. Alternatively, the μ of the road surface also decreases when oil or the like is sprinkled on the road surface due to an accident. When the μ of the road surface decreases, there is a high possibility that ABS will be activated in order to reduce the occurrence of skidding due to wheel locking during braking operation on a 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 has decreased. Therefore, the navigation device 6 of the first vehicle 4 estimates the point where the first sensor 7 detects the operation of the ABS as the road abnormal position where the road surface μ has decreased.

Further, as the second sensor 8 that detects a decrease in road surface μ, for example, an on-vehicle camera can be used. The navigation device 6A of the second vehicle 5 processes, for example, image data of the road surface captured by an on-vehicle camera (second sensor 8) attached to the windshield of the second vehicle 5, and processes data such as puddles, snow, ice, oil, etc. Determine the existence of an object that lowers μ such as. When the navigation device 6A detects an object that reduces μ, it estimates that point as a road abnormal position where the road surface μ decreases. In each of the embodiments described above, the accuracy of the estimation of road abnormality by the second sensor 8 is higher than the accuracy estimated by the first sensor 7.

Note that the types of road abnormalities to be detected and the first and second sensors 7 and 8 shown in FIG. 4 are merely examples. For example, the method for estimating the unevenness of the road surface described above is just one example, and other known techniques may be employed. For example, a suspension sensor that detects the amount of expansion and contraction of a wheel suspension device (amount of displacement of the suspension arm) and a vehicle height sensor that detects the amount of displacement of the vehicle height are used as the first sensor 7, and the amount of displacement of the suspension arm and the amount of displacement of the suspension arm are used as the first sensor 7. 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 easier to understand, the case where the report creation support system 1 temporarily registers and permanently registers the unevenness of the road surface as a road abnormality, which is the first embodiment, will be mainly explained, and the second and Description of the third embodiment will be omitted as appropriate. Note that the report creation support system 1 can perform temporary registration etc. in the second embodiment and the third embodiment as well as in the first embodiment. Further, the report creation support system 1 is also capable of processing multiple types of road abnormalities at once. That is, not only detection information of road surface irregularities but also detection information of road obstacles and a decrease in road surface μ may be collected from the first vehicle 4 simultaneously or in parallel.

The navigation device 6 of the first vehicle 4 temporarily registers information about the unevenness of the road surface detected by the first sensor 7 into 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 abnormality position based on guidance from the server device 3, as described later, and moves to the road abnormality position detected by the second sensor 8. , performs the main registration 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 (a) to (e) above. For example, the first line of the probe information shown in FIG. Detection information detected by the first sensor 7 at the position coordinates (x1, y1) of the first vehicle 4 traveling is stored. The detection information of the first sensor 7 here is, for example, data indicating a result of estimating that the road surface is uneven. Note that the sensor information is not limited to data indicating the result of estimating that there is an unevenness, but includes, for example, the wheel speed value detected by the vehicle speed sensor (first sensor 7), the fluctuation distribution of the wheel speed, the result of fuzzy inference, the unevenness Data indicating the degree etc. may also be used. Further, the sensor information may include data indicating a result of estimating that there is no unevenness, or data of a detection value that indicates that there is no unevenness.

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

Furthermore, as shown in FIG. 5, in the second row of officially registered data, vehicle image data is stored in association with the information related to (a) to (e) above. This vehicle image data is image data in which the second vehicle 5, which is equipped with an on-vehicle camera as the second sensor 8, captures an image of a road abnormal position (road surface irregularities, etc.). As will be described later, the navigation device 6A of the second vehicle 5 registers vehicle image data captured at the road abnormal position when performing 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 temporary registration and permanent registration information. The stored vehicle image data is used in road abnormal position display processing (S62 and S63 in FIG. 9), which will be described later.

Here, in general, the price of the high-precision second sensor 8 that can estimate (detect) road abnormalities with high precision 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 vehicles 5 are so-called luxury cars, road repair vehicles, or patrol vehicles, the total number of second vehicles 5 running on the road will be smaller than the total number of inexpensive first vehicles 4. It becomes less. Therefore, in the report creation support system 1 of this embodiment, the detection information by the first sensor 7 with low accuracy is temporarily registered, the second vehicle 5 is guided to the temporarily registered road abnormal position, and the second vehicle 5 is guided to the temporarily registered road abnormality position. If a road abnormality is also detected by the second sensor 8, the main registration is performed. Thereby, the reliability of the data registered in the probe information DB 22 can be improved.

Further, the server device 3 displays information on the road abnormality position that has been officially 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 road abnormality position that he or she is in charge of from the displayed road abnormality positions, and moves there using an inspection vehicle or the like. After repairing or inspecting the road, the worker 9 selects the location of the road abnormality on the display screen of the communication terminal 10 and enters information necessary for creating a report. This allows the server device 3 to automatically create a report. The server device 3 stores the created report in the report DB 24. Note that the method of utilizing the road abnormality information officially registered in the probe information DB 22 is not limited to the method of displaying it on the communication terminal 10 described above. For example, the server device 3 may provide road abnormality information that has been officially registered in the probe information DB 22 to ministries and agencies that manage roads as reference information for road repair. This allows ministries and agencies that manage roads to dispatch road repair vehicles and patrol cars to road abnormalities, and quickly take appropriate actions such as repairing roads and guiding vehicles.

Next, a schematic configuration of the communication terminal 10 owned by the worker 9 will be described using FIG. 6. In addition, in the following description, the case where the communication terminal 10 is a smartphone will be especially explained as an example. As shown in FIG. 6, the communication terminal 10 includes a data bus BUS including a CPU 71, a memory 72, and a transmitting/receiving circuit (RF) 73 that transmits and receives signals between base stations of the communication network 11. A baseband processing unit 74 that converts the RF (Radio Frequency) signal received in the circuit unit 73 into a baseband signal and converts the baseband signal into an RF signal, and an input/output unit that is an interface with a microphone 75, a speaker 76, etc. 77, a display 78 composed of a liquid crystal display panel, etc., a camera 79, an input operation section 80 composed of a touch panel, hard buttons, etc., and a GPS 81 are connected.

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

Furthermore, the memory 72 is a storage medium that stores terminal information and the like. The terminal information is the ID of the communication terminal 10 and the information (user ID, name, etc.) of the worker 9 who owns the communication terminal 10. In addition to control programs, the memory 72 also stores various application programs including a report creation processing program (see FIG. 9), which will be described later. Note that the memory 72 may be configured by a hard disk, a memory card, or the like.

Further, the display 78 is disposed on one side of the housing, for example, and uses a liquid crystal display, an organic EL display, or the like. Then, a top screen for executing various applications installed in the communication terminal 10, screens related to the executed applications (Internet screen, email screen, etc.), and various information such as images and videos are displayed. In addition, when the report creation support processing program (the report creation processing program in Figure 9) is activated, there is a remarks column for inputting the input information necessary for report creation, a send button for deciding to send data, etc. (see FIG. 11) are also displayed.

Further, the camera 79 is a small-sized imaging device configured by, for example, a camera using a solid-state imaging device such as a CCD, and is built into the back side of the communication terminal 10 . Then, with the dedicated application program activated, the user can take an image of the surrounding area by operating the input operation section 80. In this embodiment, in particular, the worker 9 uses the camera 79 to take an image of the state of the road abnormality position where the countermeasure has been taken, and the captured image data (an example of the countermeasure image data of the present application) is used to create a report. Note that image data captured by the camera 79 is stored in the memory 72.

Further, the input operation section 80 includes 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 performs control to execute various corresponding operations based on electrical signals outputted by pressing the touch panel or hard buttons of the input operation unit 80, or the like. Further, in this embodiment, the input operation unit 80 particularly receives an operation of the enter button displayed on the display 78 from the worker 9 in the report creation process. The input operation section 80 can also be configured with various keys such as number/character input keys, cursor keys for moving a cursor to select displayed contents, and enter keys for confirming selections.

Moreover, the GPS 81 can detect the current position and current date and time of the communication terminal 10 (namely, the worker 9) by receiving radio waves generated by an artificial satellite. Further, in addition to the GPS 81, a configuration may be adopted in which other devices (for example, a gyro sensor, etc.) for detecting the current position and direction of the communication terminal 10 are provided.

Next, 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 in the server device 3 will be explained based on FIG. 7. FIG. 7 is a flowchart of the temporary registration processing program and the main registration processing program according to this embodiment. First, the temporary registration processing program shown in FIG. 7 will be explained, and the actual registration processing program will be described later. Here, the temporary registration processing program is executed, for example, when the navigation device 6 of the first vehicle 4 is powered on and the first vehicle 4 starts traveling. The temporary registration processing program is a program that is executed after a predetermined period of time (for example, several minutes) has elapsed since the previous program ended, and estimates the road condition and executes temporary registration of the road abnormal position. The program shown in the flowchart in FIG. 7 below is stored, for example, in the RAM 62, ROM 63, etc. included in the navigation device 6, and is executed by the CPU 61.

Further, the temporary registration processing program is executed by, for example, starting a predetermined application program in the server device 3 when the system is started, and the processing is executed when information on the road abnormal position is received from the navigation device 6 of the first vehicle 4. will 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 information on the passing route to the subsequent second vehicle 5 that passes through the temporarily registered road abnormal 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 or ROM 33 of the server device 3, and is executed by the CPU 31.

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

Next, in S2, the CPU 61 determines whether or not it was estimated in S1 that there is an unevenness of the road surface, that is, it was estimated that there is a road abnormality. If the CPU 61 determines that there are no unevenness on the road surface (S2: NO), it ends the temporary registration processing program shown in FIG. The CPU 61 restarts the process from S1 when a predetermined period of time has elapsed since the last time the temporary registration process program ended. Thereby, while the first vehicle 4 is traveling, the navigation device 6 repeatedly estimates the unevenness of the road surface on which the first vehicle 4 is traveling. Note that the temporary registration processing program may be executed by the navigation device 6 only when a specific process such as route guidance to a destination is being executed.

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

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

Further, the CPU 61 transmits, as (c) the time of entry into the link, for example, information on the time when the first vehicle 4 entered the link on which it is traveling. Further, the CPU 61 transmits, as (d) sensor detection information, for example, information indicating that there are irregularities. Further, in the second embodiment, the CPU 61 transmits, as (d) sensor detection information, for example, information indicating that there is an obstacle, a detection value of the steering sensor, and the like. Further, in the third embodiment, the CPU 61 transmits, as (d) sensor detection information, for example, information indicating that the road surface μ is decreasing, ABS operation time, and the like. Further, the CPU 61 transmits, for example, the serial number of the navigation device 6 as (e) a vehicle ID for identifying the transmission source vehicle. Note that other information (such as a vehicle body number) that can individually identify a vehicle can be used as the vehicle ID.

On the other hand, when the CPU 31 of the server device 3 receives information instructing temporary registration from the CPU 61 (first vehicle 4) (S11), the CPU 31 of the server device 3 stores each piece of information received together with the instruction information in the corresponding column (temporary registration) of the probe information DB 22. column) (S12). This completes the temporary registration in the probe information DB 22. Note that the determination as to whether provisional registration or permanent registration should be made may be performed on the server device 3 side. For example, the CPU 61 of the navigation device 6 may transmit only the information (a) to (e) to the server device 3. Then, the CPU 31 of the server device 3 may determine whether provisional registration or permanent registration is to be performed, based on the type, model number, etc. of the sensor, for example.

After executing S12, the CPU 31 executes S13. 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 where the temporary registration was performed in S12. Here, the following second vehicle 5 that is expected to travel at the temporary registration point is, for example, the second vehicle 5 that is traveling toward the temporary registration point on the road where a road abnormality has been detected, or The server device 3 notifies the second vehicle 5 of the route passing through the registration point, and the second vehicle 5 is located within a distance or range where there is a possibility that the second vehicle 5 will take a detour and pass through the temporary registration point. 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 information (accuracy, etc.) of the second sensor 8 mounted thereon to the server device 3 while the second vehicle 5 is traveling. The CPU 31 of the server device 3 determines the second vehicle 5 existing within a predetermined distance from 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 of the second vehicle 5 considers it okay to take a detour or the like to stop at the temporary registration point, and is from several kilometers to several tens of kilometers. Based on the information of the second sensor 8 received from the second vehicle 5, the server device 3 determines whether the following It is determined that the second vehicle 5 exists (S13: YES). As will be described later, when the high-precision second sensor 8 detects a road abnormality to perform official registration (confirm registration) and display the road abnormality position based on the registered information, This is because vehicle image data captured by the second vehicle 5 is used.

If the CPU 31 determines in S13 that there is a following second vehicle 5 that is expected to travel at the road abnormal position (S13: YES), it executes S14. In S14, the CPU 31 creates a route through which the subsequent second vehicle detected in S13 passes through the temporary registration point. The CPU 31 searches for a 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 following second vehicle 5, and the server-side map information DB 23. This route can be a route from the current position to the temporary registration point, a route from the current position to the temporary registration point and back to the current position, or a path from the current position to the temporary registration point and the main path. It is a route that reaches the main road.

After executing S14, the CPU 31 executes S15. The CPU 31 transmits the passing route information created in S14 to the following second vehicle 5 (S15). In addition, when the CPU 31 detects a plurality of following second vehicles 5 in S13, the CPU 31 may transmit the passing route information to only one of them, and may send the information on the passing route to two or more second vehicles 5 respectively. It is also possible to transmit information on the route through which the vehicle passes.

Further, the method for determining the following second vehicle 5 is not limited to the method using the range centered on the temporary registration point described above. For example, the server device 3 periodically acquires information about the guidance route being guided from the second vehicle 5, and if a temporary registration point exists on the guidance route, the server device 3 transfers the second vehicle 5 to the following second vehicle. It may be determined as 5. Furthermore, based on the information acquired from the second vehicle 5, the server device 3 acquires the vehicle ID of the second vehicle 5 (such as the serial number of the navigation device 6) and the information of the second sensor 8 provided in the second vehicle 5. The second vehicle 5 may be associated and stored in the DB, and the second vehicle 5 equipped with a high-precision sensor and an on-vehicle camera as the second sensor 8 may be detected from vehicles existing within a range centered on the temporary registration point. Alternatively, the navigation device 6A (CPU 61A) of the second vehicle 5 may execute the process of acquiring information on the temporary registration point. For example, when starting guidance on a guidance route, the navigation device 6A may inquire of the server device 3 about temporary registration points that exist around the current position of the second vehicle 5 or around the guidance route to guide the driver. .

Next, 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 in the server device 3 will be explained based on FIG. Here, the registration processing program is executed by, for example, starting a predetermined application program when the navigation device 6A of the second vehicle 5 is powered on and the system is started, and the above-mentioned passing route information is sent to the server device. When received from 3, processing starts. 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 route received from the server device 3, determines passing of a 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, for example, in the RAM 62, ROM 63, etc. included in the navigation device 6A, and is executed by the CPU 61A.

Further, the main registration processing program is executed by, for example, starting a predetermined application program in the server device 3 when the system is started, and information about the road abnormal position (temporary registration point) is sent from the navigation device 6A of the second vehicle 5. The process is started when vehicle image data capturing an image of a road abnormal position is received. The main registration processing program is a program for main registering 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 or ROM 33 of 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 information on the route from the server device 3, it notifies the driver of the received route (S22). FIG. 8 shows an example of a screen guiding the route. For example, as shown in FIG. 8, the CPU 61A sends a message 91 to the effect that "there is a provisionally registered point where you would like to check the unevenness of the road surface", a guidance button 92 for providing guidance, and a cancel button 93 to the navigation device. 6 on the liquid crystal display 46. For example, when the CPU 61A receives an operation to select the guide button 92 on the operation unit 45, the CPU 61A displays the route received from the server device 3 in S21 on the liquid crystal display 46. Thereby, the second vehicle 5 can be guided to the temporary registration point. Further, when the CPU 61A receives an operation to select the cancel button 93 on the operation unit 45, the CPU 61A erases the display of the message 91 and returns to the original display screen.

Note that the method of notifying the driver of the road abnormal position is not limited to the method described above. For example, the CPU 61A acquires information on temporary registration points existing around the current location 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 driver to the temporary registration points. You may do so. Thereby, the driver can check the display on the liquid crystal display 46, determine the temporarily registered point at which he or she can stop, and pass through.

Further, the CPU 61A may present incentive information that makes the driver want to stop at the temporary registration point. This incentive information is, for example, information that stimulates the driver's desire to pass through the temporary registration point by presenting information that is useful to the driver. As an incentive service, for example, the vendor of the navigation device 6A collaborates with other companies (car dealers and insurance companies) to set up a system in which points can be accumulated by passing through temporary registration points, and the accumulated points can be used to earn points. 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 receives an operation to select the point information button 94 on the operation unit 45, the CPU 61 displays information on the points added by passing through the current temporary registration point, information on the cumulative points up to now, vehicle inspection costs and insurance costs. Information such as the number of points eligible for the discount system is displayed. Thereby, the driver can be motivated to pass through the temporary registration point.

Incidentally, the incentive service is not limited to the above-mentioned vehicle inspection fee discount system, etc. For example, by collecting highly accurate information from the second sensor 8, a more reliable probe information DB 22 can be generated. Furthermore, by using this probe information DB 22, road repairs 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, rankings may be performed for each region based on the number of times the temporary registration point has been passed and the actual registration has been executed, and the ranking may be displayed as incentive information. This ranking is a ranking of drivers who are contributing more to local road repair. Thereby, the driver can be motivated to pass through the temporary registration point for the purpose of contributing to society.

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

In addition, when the CPU 61A executes S23 to determine whether the temporary registration point has passed, the CPU 61A executes other temporary registration points until the temporary registration point is passed or the process of S23 is finished according to the above-mentioned predetermined conditions. It is not necessary to perform location notification. That is, it is not necessary to present another temporary registration point to the driver heading to the temporary registration point. In addition, the CPU 61A accumulates information on another passing route (temporary registration point) received from the server device 3 until the second vehicle 5 passes the temporary registration point, and at the timing when the second vehicle 5 passes the temporary registration point, the CPU 61A stores information on another passing route (temporary registration point). You may notify.

Further, in the third embodiment (reduction in road surface μ) shown in FIG. 4, since guidance is performed to a temporary registration point where ABS is activated, it is not preferable to guide general vehicles such as luxury cars. Therefore, in the third embodiment, it is preferable that the second vehicle 5 to be guided be a repair vehicle to be repaired or a patrol vehicle. Further, regarding the second embodiment (road obstacle), since the provisional registration is 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 depending on the degree or number of sudden steering or sudden deceleration (high probability that there is a provisionally registered obstacle).

Further, the server device 3 does not need to guide the second vehicle 5 to the temporary registration point. For example, the navigation device 6A may periodically detect a road abnormality while the second vehicle 5 is traveling, and transmit road abnormality information to the server device 3 based on the detection. Then, when the server device 3 receives road abnormality information from the second vehicle 5 (second sensor 8), it may execute the main registration. In this case, the server device 3 may perform the official registration even for points that have not been temporarily registered.

In S23 of FIG. 7, when the CPU 61A determines that the second vehicle 5 has passed the temporary registration point (S23: YES), it executes S24. In S24, the CPU 61A estimates a 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 on which the second vehicle 5 is traveling based on fluctuations in 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 travel link including the temporary registration point, and acquires the vehicle image captured by the on-vehicle camera (second sensor 8). Start acquiring image data. After passing 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 the temporary registration point. Note that 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 road abnormalities using the second sensor 8 within a predetermined range including the temporary registration point.

After executing S24, the CPU 61A executes S25. In S25, the CPU 61A determines the estimation result in S24. The CPU 61A determines whether it is estimated that there is an uneven road surface, that is, it is estimated that there is a road abnormality. If the CPU 61A determines that there are no unevenness on the road surface (S25: NO), it ends the process shown in FIG. The CPU 61 ends the route guidance, etc., and returns the display on the liquid crystal display 46 to its original state. In this case, since the guided second vehicle 5 could not detect any road abnormality, the server device 3 may perform a process of guiding another second vehicle 5 to the temporary registration point.

Further, in S25, if the CPU 61A determines that there are irregularities in the road surface (S25: YES), the CPU 61A accesses the probe information DB 22 of the server device 3 and performs official registration of the road abnormal position (S26). In S26, the CPU 61A transmits the official registration information shown in FIG. 5 (information (a) to (d)) and the information instructing the official registration to the server device 3, similarly to the provisional registration. Further, the CPU 61A transmits to the server device 3 in-vehicle image data of the location of the road abnormality captured by the in-vehicle camera when the road abnormality is detected. The time when a road abnormality is detected here is, for example, the timing at which the road abnormality estimated in S24 is detected. After executing S26, the CPU 61A ends the process shown in FIG.

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

Further, as shown in FIG. 5, the CPU 61 transmits information indicating the presence of unevenness, a detected value of the vertical acceleration sensor, etc. as the (d) sensor detection information of the official registration. In addition, in the second embodiment, the CPU 61 includes (d) sensor detection information such as information indicating that there is an obstacle, image data captured by an in-vehicle camera, image data after image processing, extracted Send information such as feature points. Furthermore, in the third embodiment, the CPU 61 transmits, as (d) sensor detection information, for example, information indicating that the road surface μ is decreasing, image data from an on-vehicle camera, and the like.

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 first vehicle 4 equipped with the low-precision first sensor 7 performs temporary registration. The second vehicle 5 to be loaded is guided. Thereby, the second sensors 8 (second vehicles 5), which are small in total, can be efficiently guided to the road abnormal position, and a highly reliable probe information DB 22 can be quickly constructed.

Note that the server device 3 may determine whether the coordinate position of the temporary registration point matches the coordinate position of the official registration. Then, if the coordinate positions do not match, the server device 3 may cancel the main registration. Alternatively, even if there is a shift in the coordinate position, the server device 3 may perform the main registration if the shift is within a predetermined range. This predetermined range is an allowable range of error in the coordinate position. For example, this includes the error range of the positional accuracy of the GPS 51, and the range in which an obstacle may move in the second embodiment.

Next, the communication terminal 10 included in the report creation support system 1 having the above configuration and the report creation processing program executed in the server device 3 will be explained based on FIG. 9. Here, the report creation processing program is executed by, for example, 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 input information from the worker 9 and requests the server device 3 to create a report in which the details of how to deal with the road abnormality are input. Note that the program shown in the flowchart in FIG. 9 below is stored, for example, in the memory 72 included in the communication terminal 10, and is executed by the CPU 71.

Further, the report creation processing program is executed by, for example, starting a predetermined application program in the server device 3 when the system is started, and starts processing when information requesting report creation is received from the communication terminal 10. be done. The report creation processing program is a program that creates a report based on input information 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 or ROM 33 of 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 creation of a report to the server device 3. The CPU 71 transmits information requesting the creation of a report to the server device 3, for example, at the timing when an application program for creating a report is started or at the timing when a predetermined operation is performed in the application program. Further, the CPU 71 transmits the information on the current location of the communication terminal 10 to the server device 3 together with the information on 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 an inspection vehicle to the registered road abnormality location and takes measures to deal with the road abnormality. The worker 9 checks and repairs road surface irregularities, collects obstacles, and takes other measures. After taking action, the worker 9 operates the communication terminal 10 to create a report. At this time, an application program is started, etc., and the above-described 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 report creation request information and position information from the communication terminal 10 in S61, it executes S62. In S62, the CPU 31 acquires map information around the current location of the communication terminal 10 from the server-side map information DB 23 based on the location information received from the communication terminal 10. The CPU 31 acquires from the probe information DB 22 the road abnormal position that is present on the map of the acquired map information and has been officially registered. The CPU 31 acquires the road abnormal position existing on the map, for example, based on the longitude and latitude information of the map information and the "position coordinates of the road abnormal position" in the main registration of the probe information DB 22.

Further, the CPU 31 acquires vehicle image data associated with the acquired road abnormal position from the probe information DB 22. This vehicle image data is image data captured by the second sensor 8 (on-vehicle camera) of the second vehicle 5, and is image data captured by capturing images of unevenness of the road surface, etc. The CPU 31 generates display data in which a mark indicating a road abnormality position and vehicle image data are arranged on a map indicated by the 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 after executing S41. The CPU 71 displays the display data received from the server device 3 on the display 78 in S42. 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 causes the display 78 to display a pin 102 indicating a road abnormality position on the map of the map information 101 in an overlapping manner, based on the display data. Further, the CPU 71 displays a speech balloon 103 for each pin 102. The CPU 71 displays the type of road abnormality occurring at the pin 102 (in the illustrated example, unevenness of the road surface), the positional coordinates of the road abnormality position, and the vehicle image data 104 obtained by capturing the road abnormality position in a balloon 103. . These pieces of information are 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 displays a current position mark 105 indicating the current position of the communication terminal 10 over the map information 101 based on the GPS information of the GPS 81. Thereby, the worker 9 operating the communication terminal 10 can confirm his/her current position and easily confirm the road abnormality position (pin 102) for which the countermeasure has been taken. Note that, based on the current position of the communication terminal 10, the server device 3 may display only the pin 102 at the road abnormality position closest to the current position on the communication terminal 10. Further, when the communication terminal 10 receives an operation to change the position of the map displayed on the display 78, the communication terminal 10 may transmit the changed position 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 it to the communication terminal 10. Thereby, the communication terminal 10 can change the displayed map and the information on the pin 102 in accordance with the operation of the worker 9. For example, the worker 9 can change the display position of the map on the display 78 to confirm the road abnormality position to which the worker 9 is traveling before riding the inspection vehicle from the office to the road abnormality position.

After executing S42, the CPU 71 executes S43. In S43, the CPU 71 determines whether selection of any one pin 102 among the plurality of displayed pins 102 has been accepted. For example, the worker 9 looks at the display 78, confirms the current position mark 105 and the position of the pin 102, and confirms the location of the road abnormality that he/she has dealt with. The worker 9 selects the pin 102 at the location of the road abnormality that has been dealt with in order to create a report. The worker 9 selects the pin 102 by performing a touch operation on the touch panel of the input operation section 80 .

The CPU 71 repeatedly executes the determination process in S43 until the selection of the pin 102 is accepted in S43 (S43: NO). Further, when determining that the selection of the pin 102 has been accepted (S43: YES), the CPU 71 transmits information on the accepted pin 102 to the server device 3 (S44). Thereby, the server device 3 can accept the selection of the road abnormality position for which a report is to be created. Note that the method of receiving the selection of the road abnormal position described above is only an example. For example, the server device 3 may display not only the officially registered road abnormal position but also temporarily registered points on the communication terminal 10, and may receive a report of the temporarily registered points.

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

After executing S44, the CPU 71 of the communication terminal 10 executes S45. Upon receiving the setting screen display data, 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 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 that displays selected input information, a selection button 111 that selects information to be displayed in the selection display field 110, and a note that allows character information to be input as input information. A field 112, an image attachment button 113, and a send button 114 are displayed on the display 78. In this embodiment, the items displayed in the selection display field 110 include, for example, (a) inspection date, (b) creator, (c) abnormality type, (d) route, (e) position coordinates, (f) Contains status.

The CPU 71 displays a 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 hard buttons of the input operation section 80 to select an arbitrary selection button 111. For example, upon receiving an operation on the (a) inspection date selection button 111, the CPU 71 displays a calendar on the display 78 and accepts selection of a date from the displayed calendar. The CPU 71 inputs the selected date into the (a) inspection date selection display column 110. Thereby, the worker 9 can input the date on which measures were taken for the road abnormal position, 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 (b) creator selection button 111, it displays the name of the worker 9 in a pull-down menu format, and accepts selection of the creator's name from among the displayed names. The CPU 71 inputs the name of the selected creator into the (b) creator selection display column 110. Thereby, the worker 9 can input the creator of the report. Note that the data on the name of the worker 9 may be data stored in the memory 72 of the communication terminal 10 or may be data acquired from the server device 3.

Further, for example, when the CPU 71 receives an operation on the (c) abnormality type selection button 111, it displays the types of road abnormalities in a pull-down menu format, and accepts selection of the type of road abnormality to be reported from among the displayed types. . The CPU 71 inputs the selected type into the (c) abnormal type selection display column 110. This allows the worker 9 to input the type of road abnormality to be reported in the report. The types of road abnormalities include, for example, road surface irregularities, road obstacles, and a decrease in road surface μ as shown in FIG. 4 . Alternatively, the type of road abnormality input on the setting screen may be information obtained by further subdividing the type of road abnormality detected by the first vehicle 4 or the second vehicle 5 shown in FIG. For example, more detailed road abnormality types such as potholes of X cm or more, manhole steps, and road cracks with a width of X1 cm to X2 cm may be used. This allows the worker 9 to check and input more detailed information about the type of road abnormality at the site of the road abnormality location.

Further, in (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 to be reported this time, is displayed. The display items (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 perform the display of (d) and (e) based on the display data received from the server device 3. The server device 3 acquires the position coordinates of the road abnormality position selected in S43 from the probe information DB 22, and based on the information of the acquired position coordinates and the information of the server-side map information DB 23, the national highway displayed in (d) It is possible to obtain information on whether the road is up or down. Further, (e) information on the position coordinates is, for example, the position coordinates of the road abnormal position that has been officially registered (selected in S43) in the probe information DB 22. Note that the CPU 71 may search map information provided in the communication terminal 10 based on the information of the pin 102 selected in S43, and display the information in (d) and (e).

Further, for example, when the CPU 71 receives an operation on the (f) status selection button 111, it displays the status types in a pull-down menu format, and accepts selection of the status type to be reported from among the displayed types. The CPU 71 inputs the selected type into the (f) status selection display column 110. The status is, for example, information indicating the result of handling. Items to be displayed in (f) include, for example, "Response started" indicating that the response to the road abnormality has started, "Response completed" indicating that the repair and other measures have been completed, and the observation of the progress of the road abnormality. Items such as "Follow-up observation required" can be adopted. By selecting item (f), the worker 9 can input the results of the actions taken into the report.

Note that 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 accept a character input from the worker 9 using the input operation unit 80 and input the received character into the selection display field 110. Alternatively, the CPU 71 may process a combination of the automatic input, selection input, and manual input described above. For example, the CPU 71 may automatically input only the national road name in the item (d) route, and may receive information such as uphill and downhill information, lane position information, etc. from the worker 9.

Further, the CPU 71 receives input to the notes column 112 based on the operation input from the input operation section 80 . The notes column 112 is a column for inputting information to be reported in the report, matters to be inherited, special notes, etc., for example. The worker 9 can input characters into the notes column 112 by operating the input operation unit 80 and selecting the notes column 112. In the example shown in FIG. 11, "Although unevenness of the road surface was confirmed, there is a regular inspection coming soon (2019/06/11), so follow-up observation is required" is input. In this way, the report creation support system 1 of the present embodiment can report not only the completion of the treatment but also progress observation and progress in the report.

Further, when the CPU 71 receives an operation on the image attachment button 113 based on the operation input from the input operation unit 80, it displays a screen for selecting image data to be attached to the report. This image data is, for example, image data (hereinafter sometimes referred to as countermeasure image data) obtained by capturing an image of a road abnormal position using the camera 79 of the communication terminal 10. After dealing with the road abnormality, the worker 9 takes an image of the road condition after the problem has been taken by the camera 79, selects the image attachment button 113, and then selects the taken action image data on the screen to take action on the report. Image data can be attached.

Further, when the CPU 71 receives an operation on the send button 114 based on the operation input from 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. Specifically, after executing S45 in FIG. 9, the CPU 71 executes S46. In S46, it is determined whether input to the setting screen is complete. The CPU 71 makes a negative determination in S46 (S46: NO) and repeatedly executes the determination in S46 until the operation input to the send button 114 is received. Further, when the CPU 71 receives an operation input on the send button 114 (S46: YES), the CPU 71 sends the input information received on the setting screen to the server device 3 (S47). The input information here includes information in the selection display field 110, information in the notes field 112, and countermeasure image data selected with the image attachment button 113 shown in FIG.

After executing S65, the CPU 31 of the server device 3 executes S66. When the CPU 31 receives input information on the setting screen from the communication terminal 10 (S66), it creates a report based on the input information (S67). FIG. 12 shows an example of a report. As shown in FIG. 12, the CPU 31 inputs, for example, the above-mentioned (a) inspection date and (b) input information 122 of the creator into the upper right corner of the report 121. Further, the CPU 31 inputs input information 123 of (c) abnormality type, (d) route, (e) position coordinates, and (f) status below the input information 122 and at the left end of the report 121. The position information 123A of (d) route and (e) position coordinates included in the input information 123 is an example of the position information of the road abnormal position in the present application. The location information 123A of (d) route and (e) location coordinates may be automatically input by the server device 3 using the probe information DB 22 or the server side map information DB 23, that is, the information on the server device 3 side. If the change is accepted on the setting screen displayed on the communication terminal 10 (see FIG. 11), the changed input information may be used. Therefore, the CPU 31 of this embodiment inputs the input information 122, 123 ((a), (b), (c), (f)) received on the setting screen shown in FIG. 11 and the position information 123A ( A report 121 is created in which (d) and (e)) are input.

Further, the CPU 31 inputs the countermeasure image data selected by the image attachment button 113 on the setting screen into the image attachment column 124 in the center of the report 121 . Note that the CPU 31 may input vehicle image data 104 (see FIG. 10) obtained by capturing an image of the road abnormal position by the second vehicle 5 into the image attachment field 124. Further, the CPU 31 inputs the input information 125 received in the notes column 112 of the setting screen to the lower part of the report 121. This allows the server device 3 to automatically create a report 121 related to the road abnormal position handled by the worker 9. Note that the structure of the report 121 shown in FIG. 11 is an example. For example, the CPU 31 does not need to provide the image attachment field 124 in the report 121. Alternatively, the CPU 31 may input map information around the road abnormal 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 receives a confirmation on whether the contents of the report 121 are correct, for example, on the display screen of the display 78 on which the report 121 is displayed (S49).

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

On the other hand, the CPU 31 of the server device 3 executes S69 after executing S68. When the CPU 31 receives information indicating that the confirmation has been completed from the communication terminal 10 (S69), it executes S70. The CPU 31 associates the report 121 created in S67 with the map information in 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 in association with the map information in the server-side map information DB 23 in the report DB 24. Thereby, the report 121 can be displayed later in association with map information.

Note that the communication terminal 10 may accept changes to the report 121 in the report 121 confirmation process in 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 need to request the communication terminal 10 to confirm the created report 121. After creating the report 121 in S67, the server device 3 may execute S70 and store it in the report DB 24.

Furthermore, the data structure of the report DB 24 is not particularly limited. For example, the server device 3 may save the report 121 in the report DB 24 by assigning identification numbers in the order in which road abnormalities occur or in the order in which the reports are created. Further, the server device 3 may store the report 121 in the report DB 24 without linking it to the map information in the server-side map information DB 23.

As explained 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 road abnormality position on the map based on the received position information 123A (S62, S63). The server device 3 accepts the selection of the road abnormality position for which the report 121 is to be created from among the displayed road abnormality positions (S64). The server device 3 receives input information 122, 123, 125 and countermeasure image data to be input into the received road abnormal 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 road abnormality 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. A worker 9 who performs road repairs, etc. selects a road abnormality position to be inspected or repaired from the road abnormality positions displayed on the map, and inputs the inspection results and repair results into input information 122, 123, 125 and countermeasures. Input as image data. The report creation support system 1 creates a report 121 in which received input information 122, 123, 125, etc. and position information 123A are input. Thereby, since road abnormalities are detected by the first vehicle 4 and the second vehicle 5 traveling on the road, only the position information 123A where the abnormality has occurred can be collected. Unlike the conventional technology, there is no need to visually check a plurality of vehicle image data obtained by sequentially capturing images of a road one by one later to discover abnormalities. That is, the worker 9 and the like do not need to carefully examine the data, such as searching for abnormal data from the collected data. In addition, input information 122, 123, 125 inspected by the worker 9 and countermeasure image data can be input into the report 121, and the current state of the road abnormality location and the situation after repair can be automatically created as the report 121. . Therefore, the workload associated with creating the report 121 can be reduced. Furthermore, unlike the prior art, since data is not collected including sections with no abnormalities, it is possible to reduce the amount of data to be accumulated (data amount of position information, vehicle image data, etc.).

In addition, 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 registered as a road abnormal position (temporary registration (S12). The report creation support system 1 detects the road provisionally registered in the probe information DB 22 based on the detection of an abnormality at the provisionally registered point by the second sensor 8 of the second vehicle 5 equipped with the highly accurate second sensor 8. The abnormal position is officially registered (S32).

According to this, the point where the low precision first sensor 7 of the first vehicle 4 detects the unevenness of the road surface is temporarily registered. That is, road abnormal positions detected by low-precision sensors are treated as provisional registration with low reliability. On the other hand, if the highly accurate second sensor 8 of the second vehicle 5 detects an abnormality at a provisionally registered point, the provisionally registered point is officially registered. That is, the road abnormal position detected by both the first and second sensors 7 and 8 is officially registered as more reliable information. Thereby, information on road conditions detected by the sensor can be appropriately registered depending on the accuracy of the sensor. More accurate information can be utilized in the process of creating the 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. Note that detecting an abnormality at a temporarily registered point does not mean only when an abnormality is detected by the second sensor 8 at a point with the same position coordinates as the temporarily registered point, but also within a certain range ( This includes the case where the second sensor 8 detects an abnormality in the error range of the GPS 51, etc.).

It should be noted that the present invention is not limited to the embodiments described above, 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 embodiments described above, the report creation support system 1 temporarily registers the road abnormality information received from the first vehicle 4, and permanently registers the road abnormality information received from the second vehicle 5. Then, the server device 3 created a report 121 regarding the officially registered road abnormal position. However, the server device 3 may create the report 121 regarding the temporarily registered road abnormal position.
Further, the server device 3 may perform a process of displaying all road abnormal positions on a map without distinguishing information about road abnormal positions received from vehicles, and may accept the creation of the report 121.

Further, the server device 3 does not need to display the vehicle image data captured by the second vehicle 5 on the communication terminal 10 in association with the road abnormal position. For example, the server device 3 may display only the pin 102 (road abnormal position in the present application) on the map on the display 78. The server device 3 also collects information on road abnormal positions from the first vehicle 4 and second vehicle 5 traveling on the road, and displays the road abnormal positions detected by each vehicle on the map on the display 78 as pins 102. It's okay.
Further, the server device 3 does not need to guide the second vehicle 5 to the temporary registration point.
Further, the server device 3 does not need to create a passage route for the second vehicle 5 to pass through the temporary registration point.

Further, in each of the embodiments described above, the navigation devices 6 and 6A temporarily and permanently register the information indicating the road abnormality, but other devices may perform the registration. For example, the navigation devices 6 and 6A may transmit the types (accuracies) of the first and second sensors 7 and 8 and the estimation results to the server device 3. Then, the server device 3 may determine whether to perform temporary registration or permanent registration based on the content of the data received from the navigation devices 6, 6A, and may execute each registration. That is, the server device 3 may execute the determination of temporary registration or permanent 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 perform estimation based on the detection information received from the first vehicle 4 and determine the unevenness of the road surface. That is, the server device 3 may perform the estimation of the road abnormality. Further, the server device 3 and the navigation devices 6 and 6A may perform part of the estimation, temporary registration, and official registration processes in coordination with each other.

Further, although the server device 3 provided data for which formal registration has been completed after provisional registration, it may also provide data for provisional registration or data for only formal registration without provisional registration.
Furthermore, the types of the first and second sensors 7 and 8 described above are merely examples. For example, in the second embodiment, the first sensor 7 may be a sensor capable of detecting either sudden steering or sudden deceleration.
Further, instead of the navigation devices 6 and 6A, it is also possible to configure the report creation support system 1 with other devices having the function of performing temporary registration and permanent registration. For example, in-vehicle equipment other than the navigation devices 6 and 6A, a mobile phone, a smartphone, a tablet terminal, a personal computer, etc. are possible.

Further, although the embodiment embodying the report creation support system according to the present invention has been described above, the report creation support system can also have the following configuration, and in that case, the following effects can be achieved. .

For example, the first configuration is as follows.
a receiving means (31) that receives positional information (123A) of a road abnormality position where a road abnormality is detected from a vehicle (4, 5); and based on the positional information received by the receiving means, A display means (31) for displaying the road abnormal position (102) on a map, and receiving the road abnormal position for creating a report (121) based on the road abnormal position displayed on the map by the display means. a first reception means (31); and input information (122, 123, 125, 124) to be input into the report of the road abnormality position received by the first reception means, which is related to handling of the road abnormality. a second reception means (31) for receiving the input information; and a report for creating the report in which the input information received by the second reception means and the position information (123A) of the road abnormality position are input. A report creation support system (1) comprising a creation means (31).
According to the report creation support system having the above configuration, the positional 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 performs road repairs or the like confirms the road abnormality position to be inspected or repaired from the road abnormality position displayed on the map, and inputs the inspection results and repair results as input information. The report creation support system creates a report containing the received input information and location information. In this way, road abnormalities are detected by vehicles traveling on the road, so only the location information where the abnormality occurs can be collected. Therefore, users such as workers do not need to carefully examine the data, such as searching for abnormal data from the collected data. In addition, input information from inspections, etc. by workers can be input into a report, and a report can be automatically created containing the current status of road abnormalities and the status after repair. Therefore, the workload associated with report creation can be reduced. Further, unlike the prior art, data is not collected including sections without abnormalities, so it is possible to reduce the amount of data to be accumulated (location information, etc.).

Further, the second configuration is as follows.
The vehicle (5) has an imaging means (8) for taking an image of a road, and the receiving means (31) receives, in addition to the position information, a vehicle image taken by the imaging means of the road where the road abnormality has been detected. 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 abnormal position (FIG. 10).
According to the report creation support system having the above configuration, since images are taken only of roads where road abnormalities have been detected, the amount of vehicle image data to be accumulated can be reduced. Furthermore, by displaying the captured vehicle image data on a map, the worker can easily visually confirm the road abnormality position and the current state of the road abnormality position.

Moreover, the third configuration is as follows.
Based on the detection of the road abnormality by the first vehicle (4), the second vehicle (5) equipped with the imaging means is configured to pass through the road abnormality position where the road abnormality was detected by the first vehicle. The second vehicle is provided with a guiding means (31) for guiding the vehicle, and the second vehicle uses the imaging means to image the road on which the road abnormality has been detected by the first vehicle, based on the guidance by the guiding means.
Vehicles running on the road have different equipment. There are also vehicles that are not equipped with a camera but are equipped with detection means for detecting road abnormalities, such as a vehicle speed sensor. Therefore, when a road abnormality is detected in a first vehicle that is not equipped with an imaging means, or when a road abnormality is detected in a first vehicle that is equipped with an imaging means but fails to take an image, the second vehicle equipped with an imaging means detects a road abnormality. to the road abnormal position. Thereby, vehicle image data can be captured and displayed on a map regarding road abnormal positions detected by other vehicles.

Further, the fourth configuration is as follows.
The guiding means (31) includes a route creating means (31) for creating a passing route for the second vehicle to pass through the road abnormality position where the road abnormality is detected by the first vehicle, and a route created by the route creating means. and transmitting means (31, 25) for transmitting the passed route to the second vehicle.
According to the report creation support system having the above configuration, by creating a passing route that passes through the road abnormal position detected by the first vehicle and transmitting it to the second vehicle, the driver of the second vehicle can create a passing route that passes through the road abnormal position detected by the first vehicle. It is possible to check whether to pass through the road abnormal position, that is, whether to follow the guidance or not. Further, there is no need for the second vehicle to search for a route that passes through the road abnormal position, and the processing load on the device of the second vehicle and the load on the driver's operations can be reduced.

Further, the fifth configuration is as follows.
The second reception means (31, 113) receives, in addition to the input information, countermeasure image data (124) related to the handling of the road abnormality, and the report creation means (31) receives information from the second reception means. The report (121) is created in which the received input information (122, 123, 125), the countermeasure image data, and the position information (123A) are input.
According to the report creation support system having the above configuration, the worker actually moves to the location of the road abnormality confirmed on the map, takes measures such as inspection and repair, and then uses the image data of the road, etc. can be submitted by the second reception means. This makes it possible to automatically create a report that includes location information, input information, and image data.
