The server apparatus 3 includes a computer unit including a CPU, a RAM, a ROM, a storage device such as hardware, and an input/output port, which are not shown.
The hard disk device of the server device 3 stores a program for causing the server device 3 to function as the information collection unit 31 and the information management unit 32. That is, the CPU executes the program stored in the hard disk device, and thereby the server device 3 functions as the information collection unit 31 and the information management unit 32.
The server apparatus 3 includes a communication device 33, and the communication device 33 communicates with the in-vehicle apparatus 2 or the information terminal 4 via a communication medium such as a wireless communication network to transmit and receive information.
The information collection unit 31 stores the information about the road surface environment received from the in-vehicle device 2 in the hard disk device of the server device 3.
The information collection unit 31 transmits the information on the road surface environment stored in the hard disk device of the server device 3 to the information terminal 4 in response to a request for the information on the road surface environment from the information terminal 4.
Upon receiving evaluation information of road surface environment-related information described later from the information terminal 4, the information collection unit 31 stores the evaluation information in association with road surface environment-related information corresponding to the evaluation information stored in the hard disk device of the server device 3.
When receiving new report information of information on the road surface environment, which will be described later, from the information terminal 4, the information collection unit 31 stores the new report information as information on the road surface environment in the hard disk device of the server device 3.
The information management unit 32 retains or discards the information about the road surface environment stored in the hard disk device of the server device 3 based on the evaluation information.
The information management unit 32 calculates the degree of reliability from the evaluation information, for example, retains information on the road surface environment with a high degree of reliability, and discards information on the road surface environment with a low degree of reliability.

The information terminal 4 includes a computer unit having a CPU, a RAM, a ROM, a flash memory, an input port, and an output port.
The ROM of the computer unit stores an OS (Operating System) for causing the computer unit to function as the information terminal 4. That is, the CPU executes the OS stored in the ROM, thereby the computer unit functions as the information terminal 4.
The information terminal 4 includes, for example, a smartphone or a car navigation system.
The information terminal 4 includes an operation unit 41, a display unit 42, a positional information detection unit 43, a communication unit 44, and an evaluation unit 45.
The operation unit 41 receives an operation input from a user. The operation unit 41 includes, for example, a touch sensor, a switch, and the like.
The display unit 42 displays the image created by the evaluation unit 45. The display section 42 includes an image display device such as a liquid crystal display.
The position information detecting unit 43 receives radio waves from GNSS satellites via a GNSS antenna, not shown, and acquires information such as the latitude and longitude of the current position from information included in the received radio waves.
The communication unit 44 communicates with the server apparatus 3 and the like via a communication medium such as a wireless communication network to transmit and receive information.
The evaluation unit 45 includes a program that operates on the OS of the information terminal 4. The evaluation unit 45 acquires information, displays an image, or transmits information by controlling the operation unit 41, the display unit 42, the positional information detection unit 43, the communication unit 44, and the like by the OS of the information terminal 4.
The evaluation unit 45 allows the user to input an evaluation of the information on the road surface environment stored in the server device 3 through the operation unit 41.
The evaluation unit 45 transmits the evaluation of the information on the road surface environment input by the user to the server device 3.
The evaluation unit 45 displays, for example, the image shown in fig. 2 as an initial screen after the program is started on the touch panel 46 in which the display unit 42 and the operation unit 41 are integrated. Here, the case of unevenness of the road surface is exemplified as the road surface environment.
As shown in fig. 2, an inquiry button 101, a new button 102, a user information edit button 103, and an end button 104 are displayed in the initial screen. When the display area of each button is touched, the evaluation unit 45 determines that the corresponding process is selected, and performs the process.
When the inquiry button 101 is selected, the evaluation unit 45 acquires the position information of the current position from the position information detection unit 43, and transmits a transmission request of information on the road surface environment including the position information to the server device 3 through the communication unit 44.
Upon receiving a transmission request for information on the road surface environment, the information collection unit 31 of the server device 3 returns information on the road surface environment that exists within a predetermined range from the position, based on the position information included in the transmission request. This can suppress evaluation by a user who has a low possibility of grasping the road surface environment, and can improve the reliability of the evaluation. In addition, the communication load or the operation load of the server apparatus 3 or the information terminal 4 can be reduced.
Upon receiving the information on the road surface environment from the server device 3, the evaluation unit 45 displays the image shown in fig. 3 on the touch panel 46 as an evaluation screen.
As shown in fig. 3, the evaluation screen displays a presence/absence switch 105, a position display unit 106, a type selection unit 107, a persistence selection unit 108, and a report button 109.
The presence/absence switch 105 selects the presence or absence of unevenness at a position displayed on the position display unit 106. The evaluation unit 45 switches between the selection of "presence" and "absence" every time the display area of the presence/absence switch 105 is touched, and changes the display to the selected state.
The position display unit 106 is a portion that displays a position where information on the road surface environment (irregularities on the road surface) is present.
The position display unit 106 displays, for example, a map of a predetermined range around the current point, and displays an icon at a position on the map where information on the road surface environment (unevenness of the road surface) is present. When 1 of the icons is touched, the evaluation section 45 displays a mark 110 at the corresponding position, and displays a position information display section 111 and an address display section 112. In this case, the user may correct the current position to an arbitrary position on the map.
The evaluation unit 45 displays position information such as latitude, longitude, and altitude of the position corresponding to the position information display unit 111. The evaluation unit 45 displays the address of the position corresponding to the address display unit 112.
Note that the mark 110 may be displayed at a position closest to the current position of the information terminal 4 where information on the road surface environment exists, and the position information display unit 111 and the address display unit 112 may be displayed.
The type selection unit 107 selects the type of road surface environment (unevenness of the road surface) from, for example, a convex, a concave, a deceleration strip, a road surface crack, and the like. The evaluation unit 45 displays, for example, a pull-down list for selecting the type of road surface environment (unevenness of the road surface).
The persistence selecting unit 108 selects persistence of the road surface environment (unevenness of the road surface) from, for example, permanent or temporary. The evaluation unit 45 displays, for example, a permanent switch button (toggle button)113 and a temporary switch button 114, and allows any one of the switch buttons to be selected.
The report button 109 transmits the evaluation selected by the presence/absence switch 105, the type selection unit 107, and the persistence selection unit 108 to the server apparatus 3.
When the report button 109 is selected, the evaluation unit 45 transmits information selected by the presence/absence switch 105, the type selection unit 107, and the continuity selection unit 108 to the server device 3 as evaluation information together with information on the road surface environment at the position selected by the position display unit 106.
When receiving evaluation information of information on the road surface environment from the information terminal 4, the information collection unit 31 of the server device 3 stores the evaluation information in association with corresponding information on the road surface environment stored in the hard disk device of the server device 3.
In fig. 2, when the new button 102 is selected, the evaluation unit 45 displays the image shown in fig. 4 on the touch panel 46 as a new report screen.
As shown in fig. 4, a position display unit 106, a category selection unit 107, a persistence selection unit 108, and a new report button 115 are displayed on the new report screen.
The evaluation unit 45 acquires the position information of the current position from the position information detection unit 43, for example, displays a map of a predetermined range of the current position, displays a mark 110 on the current position, displays the position information such as the latitude, longitude, and altitude of the current position on the position information display unit 111, and displays the address of the current position on the address display unit 112.
When the marker 110 on the map is moved by a touch operation or the like on the touch panel 46, the evaluation unit 45 displays the position information of the moved position on the position information display unit 111 and the address on the address display unit 112.
This makes it possible to easily specify the position of the road surface environment (the irregularities of the road surface) on the map without being affected by the current position or whether or not the vehicle is traveling. Further, since the position can be confirmed by the position information or the address, the position of the road surface environment (the unevenness of the road surface) can be specified with high accuracy.
The evaluation unit 45 performs the same processing as the evaluation screen for the type selection unit 107 and the persistence selection unit 108.
When the new report button 115 is selected, the evaluation unit 45 transmits the information selected by the position display unit 106, the category selection unit 107, and the persistence selection unit 108 to the server apparatus 3 as new report information.
When receiving new report information of the information on the road surface environment from the information terminal 4, the information collection unit 31 of the server device 3 stores the new report information as the information on the road surface environment in the hard disk device of the server device 3. The information collection unit 31 may store information on the type of road surface environment or information on the continuity of the road surface environment as evaluation information in the hard disk device of the server device 3.
The information collection unit 31 may store the information on the road surface environment as the information on the road surface environment only when the position of the information on the road surface environment from the information terminal 4 and the position of the information terminal 4 are within a predetermined range. This makes it possible to exclude information from a user who has a low possibility of grasping the road surface environment, and to improve the reliability of information relating to the road surface environment. In addition, the communication load or the operation load of the information terminal 4 can be reduced.
In fig. 2, when the user information edit button 103 is selected, the evaluation unit 45 displays a user information screen on the touch panel 46, although not shown. In the user information screen, confirmation of user information, editing of user information, a history of reports up to now, registration of new users, and the like can be performed.
In this way, by registering the user as a member, the number and quality of new reports based on the evaluation of the information on the road surface environment or the information on the road surface environment are given a benefit, and the evaluation of the information on the road surface environment or the new reports of the information on the road surface environment can be promoted.
In fig. 2, when the end button 104 is selected, the evaluation unit 45 ends the process.
The information management unit 32 of the server apparatus 3 retains or discards the information on the road surface environment stored in the hard disk drive, based on the thus accumulated evaluation information.
The information management unit 32 obtains the degree of reliability of the position from the number of pieces of information "present" in the road surface environment, for example, among the pieces of evaluation information regarding one piece of information on the road surface environment. The information management unit 32 increases the degree of reliability of the position as the number of pieces of information "present" in the road surface environment of the evaluation information increases.
The information management unit 32 may determine the degree of reliability of the position based on the ratio of the information indicating "presence" of the road surface environment to the total number of evaluation information for one piece of information on the road surface environment. In this case, the higher the ratio of the information that the road surface environment is "present", the higher the degree of reliability of the position.
The information management unit 32 divides the degree of reliability of the position into, for example, several stages of levels, retains information on the road surface environment with the degree of reliability of the position higher than a predetermined level, and discards information on the road surface environment with the degree of reliability of the position being equal to or lower than the predetermined level.
In this way, the information on the road surface environment with a high degree of reliability is retained and the information on the road surface environment with a low degree of reliability is discarded, so that the reliability of the information on the road surface environment can be ensured.
The information management unit 32 may also compare the number of pieces of information whose road surface environment is "present" in the evaluation information or the ratio of pieces of information whose road surface environment is "present" with a predetermined value, and retain or discard the information about the road surface environment.
The information management unit 32 may transmit the information about the road surface environment thus retained to the information terminal 4, and display the position, type, continuity, and the like of the information terminal 4. Further, the information terminal 4 mounted on a vehicle such as a car navigation system may issue an alarm when a predetermined road surface environment is present within a predetermined distance in the traveling direction of the vehicle based on the received information on the road surface environment. As the condition for issuing the alarm, a condition in which the speed of the vehicle is equal to or higher than a predetermined value or the vehicle does not decelerate, or the like may be further added.
The information management unit 32 obtains the reliability degree of each of the road surface environments, for example, from the number of each of the road surface environment types (convex, concave, deceleration strip, road surface crack, and the like) in the evaluation information for one piece of information on the road surface environment. The information management unit 32 increases the degree of reliability as the number of road surface environment types selected increases.
The information management unit 32 retains the type having the highest degree of reliability as the information on the road surface environment. The information management unit 32 may divide the degree of reliability of the type into, for example, several stages, reserve, as the information on the road surface environment, the type having a degree of reliability higher than a predetermined level, and discard the type having a degree of reliability lower than the predetermined level.
The information management unit 32 obtains the reliability degree of each of the evaluation information on one piece of road surface environment based on the number of each of the persistence (permanent, temporary, etc.) of the road surface environment. The information management unit 32 increases the degree of reliability as the number of road surface environments selected increases.
The information management unit 32 retains the continuity of high reliability as the information about the road surface environment. The information management unit 32 may divide the reliability degree of the persistence into several stages, for example, retain the persistence of the reliability degree of the persistence higher than a predetermined level as the information on the road surface environment, and discard the persistence of the reliability degree of the persistence lower than the predetermined level.
Such determination of the retention or the discard of the information on the road surface environment may be performed when a predetermined period of time has elapsed after the information on the road surface environment has been registered.
When the evaluation information is registered in a predetermined number or more, it may be determined whether the information on the road surface environment is to be retained or discarded.
The road surface environment detection process of the in-vehicle device 2 of the road surface environment information collection system 1 of the present embodiment configured as described above will be described with reference to fig. 5.

In step S11, the information collection unit 31 receives information about the road surface environment via the communication device 33.
In step S12, the information collection unit 31 stores the received information on the road surface environment in the hard disk device of the server device 3, and ends the process.
The road surface environment evaluation process by the evaluation unit 45 of the information terminal 4 of the road surface environment information collection system 1 according to the present embodiment will be described with reference to fig. 7. The road surface environment evaluation processing described below is started when the query button 101 on the initial screen is touched.
In step S21, the evaluation unit 45 transmits a transmission request of information on the road surface environment including the position information detected by the position information detection unit 43 to the server device 3 via the communication unit 44.
In step S22, the evaluation unit 45 receives information on the road surface environment from the server device 3 via the communication unit 44.
In step S23, the evaluation unit 45 displays the evaluation screen shown in fig. 3 on the display unit 42.
In step S24, the evaluation unit 45 determines whether or not the report button 109 of the evaluation screen is touched and pressed. When determining that the report button 109 is not pressed, the evaluation unit 45 repeats the process of step S24.
When it is determined in step S24 that the report button 109 has been pressed, the evaluation unit 45 transmits the above-described evaluation information to the server device 3 together with the information on the road surface environment as the evaluation target in step S25, and ends the process.
Road surface environment information transmission processing by the information collection unit 31 of the server device 3 of the road surface environment information collection system 1 according to the present embodiment will be described with reference to fig. 8. The road surface environment information transmission process described below is started when the information collection unit 31 of the server device 3 starts operating, and is executed at predetermined time intervals.
In step S31, the information collection unit 31 receives a request for transmission of information relating to the road surface environment via the communication device 33.
In step S32, the information collection unit 31 returns information on the road surface environment existing within a predetermined range of the position information included in the received transmission request via the communication device 33, and ends the process.
The evaluation information reception process of the information collection unit 31 of the server device 3 of the road surface environment information collection system 1 according to the present embodiment will be described with reference to fig. 9. The evaluation information reception process described below is started when the information collection unit 31 of the server device 3 starts operating, and is executed at a predetermined time interval.
In step S41, the information collection unit 31 receives the evaluation information via the communication device 33.
In step S42, the information collection unit 31 associates the received evaluation information with the corresponding information on the road surface environment, stores the information in the hard disk device of the server device 3, and ends the process.
The information management process of the information management unit 32 of the server device 3 of the road surface environment information collection system 1 according to the present embodiment will be described with reference to fig. 10. The information management processing described below is started when the information management unit 32 of the server device 3 starts operating, and is executed for each piece of information on the road surface environment at preset time intervals.
In step S51, the information management unit 32 determines whether or not a predetermined period of time has elapsed since the target information on the road surface environment was registered in the hard disk device of the server device 3. When determining that the predetermined period of time has not elapsed since the target information on the road surface environment was registered, the information management unit 32 ends the process.
When it is determined in step S51 that the predetermined period has elapsed since the target information on the road surface environment was registered, the information management unit 32 determines in step S52 whether or not evaluation information is registered in the target information on the road surface environment.
When it is determined in step S52 that the evaluation information is registered in the information on the road surface environment as the target, in step S53, the information management unit 32 obtains the degree of reliability of the information on the road surface environment as the target as described above.
In step S54, the information management unit 32 determines whether or not the degree of reliability of the target information on the road surface environment is higher than a predetermined level. When it is determined that the degree of reliability of the information on the road surface environment as the target is higher than the predetermined level, the information management unit 32 retains the information on the road surface environment as the target in step S55, and ends the process.
If it is determined in step S52 that evaluation information is not registered in the information on the target road surface environment, or if it is determined in step S54 that the degree of reliability of the information on the target road surface environment is not higher than the predetermined level, the information management unit 32 discards the information on the target road surface environment in step S56, and ends the process.
In this way, in the above-described embodiment, the information on the road surface environment detected by the road surface environment detecting unit 23 of the in-vehicle device 2 is collected by the information collecting unit 31 of the server device 3, and the information on the road surface environment is evaluated by the user's operation of the information terminal 4, so that it is possible to suppress erroneous information on the road surface environment from being retained or temporary information on the road surface environment from being retained continuously.
In the above-described embodiment, the information on the current position is received from the GNSS satellite, but the position information may be acquired from SLAM (Simultaneous Localization and Mapping) information.
In the above-described embodiment, the position information of the current position is acquired when the inquiry button 101 is selected, but the position information of the current position may be automatically acquired while an initial screen is displayed after the program is started.
In addition, although the above-described embodiment discloses the system that manages the information on the unevenness of the road surface as the information on the environment of the road surface, the system may be configured to manage the information on the flooded snow or the accumulated snow as the information on the environment of the road surface in addition to the unevenness of the road surface in the same manner as the embodiment.
The information management unit 32 of the server device 3 is configured to retain or discard the information on the road surface environment stored in the hard disk device based on the accumulated evaluation information, but may be configured to retain and manage the information as past information instead of discarding the information. The information related to the road surface environment is retained as the past information or other information without discarding the information while stopping the retention of the information, and thus the information can be flexibly applied as information such as the aged change or the service life of the road surface environment at the same position.
Although embodiments of the present invention have been disclosed, it will be apparent to those skilled in the art that modifications can be made without departing from the scope of the invention. It is intended that all such modifications and equivalents be included in the following claims.
