Description

[Technical field]

[0001] The present disclosure relates to an information processing device, an information processing method, and an information processing program. [Background technology]

[0002] There is known a technique for determining a travel route of a moving body equipped with tires and loaded with goods. For example, a technique for determining a travel route of a moving body based on the topography, the amount of goods, the travel distance of the moving body, etc. has been proposed (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-160093 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, at work sites such as quarrying sites and mines, road surface conditions such as elevation difference, number and curvature of curves, load of transported goods, and unevenness vary greatly depending on the travel route, and the load on the tires varies depending on the route, so the heat generated in the tires also differs and the tire deterioration also differs. For this reason, tires attached to a moving body that travels many travel routes with heavy loads deteriorate and break down early, while tires attached to a moving body that travels many travel routes with light loads can be used for a long time, and the usable period (also called life) of the tire is not uniform. In such a usage environment, there is a risk of unexpected tire failure and shortening of tire life, and there are challenges in using the tires well. In response to this, a usage method that takes into account the load on the tires by selecting the travel route is conceivable, but if the route of the moving body is simply determined based on the topography, the travel distance of the moving body, etc. as described in Patent Document 1, the determined route may be a route that generates more heat in the tires than other routes and deteriorates the tires more rapidly, and may not be the optimal route for the moving body. Therefore, there is room for improvement in determining the travel route of the moving body on which the tire is mounted. It is also difficult to confirm the optimal route that a moving object can travel while taking into account the heat generated by the tires when traveling. For example, even when controlling a vehicle using an Autonomous Haulage System (AHS), it is required to determine or confirm the route for traveling of the moving object based on the tire temperature.

[0005] The present disclosure aims to provide an information processing device, an information processing method, and an information processing program that can confirm the route along which a moving object equipped with a tire will travel, taking into account the heat generated when the tire is traveling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, embodiments for implementing the technology of the present disclosure will be described in detail with reference to the drawings. In addition, components and processes that have the same actions and functions are given the same reference numerals throughout the drawings, and duplicated explanations may be omitted as appropriate. In addition, the present disclosure is not limited to the following embodiments, and can be implemented with appropriate modifications within the scope of the purpose of the present disclosure.

[0026] <Information processing system> FIG. 1 shows a schematic configuration of an information processing system 1 according to an embodiment. The information processing system 1 is a system that collects information related to tires attached to a moving object 2, such as a vehicle traveling in a mine, and performs processing related to the tire condition of the tire. As shown in Fig. 1, the information processing system 1 includes a user terminal 3 and a server device (hereinafter referred to as "server") 5 that operates as an information processing device. The server 5 is an example of an information processing device of the present disclosure.

[0027] The user terminal 3 and the server 5 are connected to each other via a network 6. The network 6 is any network that can be connected by wire or wirelessly, such as a telephone line, a LAN, a WAN, the Internet, a wide area Ethernet network, etc. The network 6 may be configured to connect the mobile body 2 to a communication device (not shown) equipped on the mobile body 2 so that information can be exchanged with the mobile body 2.

[0028] The information processing system 1 may be realized by including a configuration of a network environment including a virtual network in which a part of the network and a part or all of the devices are virtualized on a virtual space called a cloud. For example, the server 5 may be formed on a virtual space called a cloud, and a client terminal known as a client-server system may be connected to the server 5 via a network 6 to operate the server 5. In addition, in order to ensure redundancy of the information processing system 1, a plurality of servers 5 may be connected via a network.

[0029] Also, FIG. 1 shows an example in which a user terminal 3 is connected to the network 6. The present disclosure is not limited to a case in which one user terminal 3 is connected to the network, and multiple terminal devices may be connected as the user terminal 3. For example, the user terminal 3 may include one or more terminals provided within the same company or base. As an example of multiple user terminals 3, a worker terminal used by a user who is a worker performing work related to moving objects and tires, a manager terminal used by a user who is a manager who manages the work, and a supervisor terminal used by a user who is a supervisor who manages the work may be provided and linked together.

[0030] In the present disclosure, the term "tire" refers to an elastically deformable member attached to a moving body 2 such as a vehicle traveling in a mine, and is a concept that includes a member that can be attached and detached from the moving body. The tire in question includes a pneumatic tire.

[0031] The tire heat information is an example of a physical quantity that indicates the tire condition related to the heat of the tire, and is a concept that includes at least the temperature of the tire. The tire heat information can include the internal pressure, such as the air pressure of a pneumatic tire, and the internal temperature of the pneumatic tire. That is, the tire heat information can apply, for example, a physical quantity that indicates the thermal state of a tire constituent member. Examples of tire constituent members are members such as beads, carcass, belts, and tread rubber. In addition, the physical quantity that indicates the thermal state of a tire constituent member can apply, for example, the temperature of the tire constituent member.

[0032] Generally, the temperature of a tire during running differs for each component. The temperature of each tire component can be calculated, for example, by attaching a sensor for measuring temperature in a chamber (i.e., the space between the inner surface of the tire and the rim wheel), measuring the temperature in the chamber, and converting the measured temperature in the chamber into the temperature of each tire component. For example, by using a predetermined calculation formula to convert the temperature in the chamber into the temperature of each tire component (tread, belt, bead, etc.), the temperature of the component (tread, belt, bead, etc.) can be calculated from the measured temperature in the chamber. In addition, the temperature of each tire component such as the tread, belt, bead, etc. can also be calculated by adding a certain constant based on past data to the measured temperature in the chamber.

[0033] Alternatively, the tire temperature can be predicted by known prediction methods depending on the surrounding environment of the tire and the tire running conditions.

[0034] In this embodiment, it is possible to apply a thermal history indicating the tire heat that changes from moment to moment as the tire heat information. The thermal history indicates the change characteristics of the tire temperature measured in time series, and can be calculated, for example, by integrating the tire temperature measured in time series by the tire running time or the like. The thermal history can correspond to the degree of deterioration of the tire including the tire constituent members. The tire heat information and the thermal history can be used as an example of an index for predicting the risk of deterioration of the tire including the tire constituent members.

[0035] The moving object 2 travels from a first point, which is a point from the current location to the destination, to a second point via an arbitrary route. The route from the first point to the second point may be one route or a series of routes passing through a plurality of points. At work sites such as a quarrying site or a mine, the load on the tires changes depending on at least one of the travel distance, the travel speed, the load, and the elevation difference between the stay point and the travel point. That is, at work sites such as a quarrying site or a mine, the heat generated in the tires changes depending on the travel route, so the load on the tires differs for each route. For this reason, when determining the route on which the moving object 2 travels, it is preferable to take this load into consideration. Therefore, in this embodiment, route information in which thermal load information is associated with the route on which the moving object 2 travels is used (details will be described later). Thermal load information is a physical quantity related to the heat generated in the tires, and travel information and tire temperature increase / decrease information can be applied.

[0036] The travel information is an example of a physical quantity indicating the tire state related to the tire travel. For example, the travel information may include information such as the travel time, travel distance, travel speed, and tire rotation number of the tire. The travel information may include information such as the remaining tread depth (RTD), which is the amount of change in the tire structure that changes with travel. Other examples of the amount of change in the tire structure may include the shape, size, such as width, and depth of the grooves provided in the tire, the thickness of the tire tread portion, and the amount of change in the degree of wear of the tire tread portion, such as uneven wear. The travel distance is preferably applied as the travel information. As the measurement unit that measures the travel information, for example, a known sensor that can measure at least one of the time and distance that the tire has traveled by sensing the rotation of the tire can be used. The remaining tread depth may be directly measured by a measurement sensor, or may be derived from an image captured by a camera or the like. The travel distance may be, for example, a record of a GPS.

[0037] The tire temperature increase / decrease information is a physical quantity indicating an increase or decrease in tire temperature that changes in a tire that has traveled a route. The tire temperature increase / decrease information may be a tire temperature increase / decrease degree indicating a degree of increase or decrease in the tire temperature according to heat generated in the tire.

[0038] <Mobile object> An example of a moving object 2 such as a vehicle traveling in a mine is shown in Fig. 2. Fig. 2 conceptually shows a configuration including an on-board device 24 that collects tire heat information and the like.

[0039] In this embodiment, the moving body 2 is provided with a total of six tires 20, one tire each on the front left and right and two tires each on the rear left and right. The tires 20 are provided with a sensor module 22. The sensor module 22 measures the tire state, that is, acquires and transmits tire heat information. The sensor module 22 may measure travel information in addition to tire heat information. In this embodiment, the sensor module 22 measures and transmits at least tire heat information. In addition, in FIG. 2, the tires 20 and the sensor module 22 are given symbols according to their positions on the moving body 2. That is, the tire provided on the front right side of the moving body 2 in the traveling direction is indicated as tire 20 (FR), and the tire provided on the front left side is indicated as tire 20 (FL). In addition, for the two tires 20 provided on the rear right side, the outer tire is indicated as tire 20 (BRO) and the inner tire is indicated as tire 20 (BRI). Similarly, of the two tires 20 provided on the rear left side, the outer tire is indicated as tire 20 (BLO) and the inner tire is indicated as tire 20 (BLI). In the following explanation, symbols are used when describing the position of the tires on the moving body 2, but otherwise the tires 20 and sensor module 22 are collectively referred to.

[0040] In this embodiment, the moving body 2 is described as having six tires 20, but the technology of the present disclosure is not limited to this. For example, it is applicable to a moving body 2 having three or more tires 20. It is preferably applicable to a moving body 2 having four to ten tires 20, and is also applicable to a moving body 2 having ten or more tires 20. In addition, the arrangement of the tires 20 on the moving body 2 is not limited to an equal number of tires on the left and right, and the number may be determined according to the position of the tires 2 relative to the moving body 2. Furthermore, the arrangement of the tires 20 is not limited to front-rear and left-right. For example, the tire 20 may be arranged in the center between at least one of the front-rear and left-right.

[0041] The moving object 2 is equipped with an on-board device 24 that collects and transmits information related to tires (temperature data indicating tire heat information in this embodiment). The on-board device 24 acquires information from each sensor module 22. The sensor module 22 is attached to the wheel of the tire 20, or inside the tire or on the vehicle body outside the tire, measures at least the temperature of the tire 20, and transmits the measured temperature data to the on-board device 24.

[0042] The vehicle-mounted device 24 receives the temperature data of each tire sent from the sensor module 22, and controls the transmission of the tire temperature data associated with the mounting position of the tire to the outside of the moving object 2. The mounting position of the tire can be specified from a correspondence table that associates the mounting position of the tire with the unique identification code of the sensor module 22 of the tire. The vehicle-mounted device 24 includes an electronic control unit (Electric Control Unit / ECU), a transmitting / receiving unit, and a memory (not shown). The memory (not shown) can record the correspondence table that associates the mounting position of the tire with the unique identification code of the sensor module 22, and information from the sensor module 22 (temperature data of the tire 20) as a log. The vehicle-mounted device 24 can have a function of outputting the log recorded in the memory (not shown) to the outside of the moving object 2.

[0043] In this embodiment, a case will be described in which the vehicle-mounted device 24 acquires and records temperature data from the sensor module 22 and outputs the temperature data to the outside of the moving object 2, but the present disclosure is not limited to this. For example, data from the sensor module 22 may be directly output to an external device such as the server 5 via the network 6 without going through the vehicle-mounted device 24. In this case, the correspondence table related to the sensor module 22 may also be stored in a device included in the information processing system 1 (for example, the server 5) without being stored in the vehicle-mounted device 24.

[0044] Furthermore, the tire temperature data is provided with time information when the data is transmitted from the sensor module 22. This makes it possible to identify the date and time of the tire temperature data.

[0045] Furthermore, the vehicle-mounted device 24 may acquire and transmit at least one of the travel amount of the tire (e.g., the travel time, travel distance, and tire rotation count of the tire) and the amount of change in the tire structure (e.g., the remaining tread depth) as the travel information. Note that the travel information is not limited to being acquired by the vehicle-mounted device 24. For example, the travel information may be acquired by measuring it using an external device of the moving object 2.

[0046] FIG. 3 shows a cross-sectional view of an example of the structure of the tire 20. 3 shows a tire tread portion TR, a tire belt BL, and a carcass CS as typical tire components of the tire 20. Information related to the tire 20 (e.g., remaining groove depth, temperature data of the tire 20) is measured by a measuring unit 34 (illustrated) such as a measuring device or a sensor module 22.

[0047] <User device> Next, an example of the configuration of a terminal in the information processing system 1 according to the embodiment will be described. FIG. 4 shows an example of the configuration of the user terminal 3. The user terminal 3 is a terminal device provided at a base where processing is performed on a tire attached to a moving object 2 such as a vehicle (for example, a management base where the condition of the tire is managed). A user who operates the user terminal 3 performs processing on the tire based on the tire condition of the tire. The user terminal 3 transmits information related to the tire (for example, tire heat information, driving information, etc.) to the server 5, and receives a reply from the server 5 as a response thereto. Note that a general-purpose computer device such as a personal computer (PC) can be applied as the user terminal 3.

[0048] The user terminal 3 includes a computer main unit 30, which includes a CPU 30A, a RAM 30B, a ROM 30C, and an I / O 30D, which are connected to one another via a bus 30E. An auxiliary storage device 35, which can be realized by a HDD, a non-volatile flash memory, or the like, is connected to the bus 30E. Also, a communication unit 31 that communicates with an external device, an input unit 32 through which the user inputs data, and a display unit 33 through which the user checks the data are connected to the I / O 30D.

[0049] A user terminal program 35P can be stored in the auxiliary storage device 35. The user terminal 3 reads the user terminal program 35P from the auxiliary storage device 35, loads it in the RAM 30B, and executes processing. As a result, the user terminal 3 that executes the user terminal program 35P operates as a device that performs processing on the tire condition of tires in the store. The user terminal program 35P may be provided by a recording medium such as a CD-ROM.

[0050] In addition, the auxiliary storage device 35 stores various data 35D used by the user terminal 3.

[0051] The communication unit 31 is capable of acquiring information, that is, tire temperature data, which is tire heat information, from the vehicle-mounted device 24 of the moving object 2 via a wired or wireless connection.

[0052] A measurement unit 34 that measures the tire condition can be connected to the I / O 30D. The measurement unit 34 is a measurement device that measures information related to tire running. In this embodiment, information on remaining tread depth (RTD), which is a change in tire structure, can be applied as an example of the information related to tire running, and a measurement device that measures the remaining tread depth of the tire 20 can be applied as the measurement unit that measures the remaining tread depth.

[0053] It is not essential that the measurement unit 34 is connected to the user terminal 3. For example, input may be made from the input unit 32 instead of the measurement unit 34.

[0054] <Server> Next, an example of the configuration of the server 5 will be described with reference to FIG. The server 5 is an example of a server device connected to the network 6, and has a function of acquiring information related to tire heat (i.e., tire heat information) from the user terminal 3 and transmitting information to assist in processing for the traveling of the moving object 2. The server 5 includes a computer main body 50, which includes a CPU 50A, a RAM 50B, a ROM 50C, and an I / O 50D, which are connected to each other via a bus 50E. An auxiliary storage device 55 is connected to the bus 50E. Also, a communication unit 51 that communicates with devices on the network 6, an input unit 52 for inputting data by the user, and a display unit 53 are connected to the I / O 50D. Note that, when the server 5 is configured to be operable by a client terminal (not shown), the input unit 52 and the display unit 53 are not essential components.

[0055] The auxiliary storage device 55 stores various data 55D used by the server 5. The auxiliary storage device 55 also stores a table 55T indicating information for supporting processing for a route along which the moving object 2 travels, and a server program 55P. The table 55T will be described later.

[0056] The server 5 reads the server program 55P from the auxiliary storage device 55, loads it in the RAM 50B, and executes the processing. The server 5 that executes the server program 55P operates as an information processing device that outputs information to support processing for the route along which the moving object 2 travels in response to information from the user terminal 3.

[0057] FIG. 6 is a block diagram showing an example of a functional configuration of the server 5 according to the present embodiment. 6, the CPU 50A of the server 5 executes a server program 55P to function as an information processing device of the present disclosure. The information processing device includes functional units functioning as an acquisition unit 500, a calculation unit 502, and a control unit 504, respectively. The acquisition unit 500 is an example of the acquisition unit of the present disclosure, and the control unit 504 is an example of the control unit of the present disclosure.

[0058] The acquisition unit 500 has a function of acquiring information output from the user terminal 3, and acquires at least the tire temperature, which is tire heat information of the tires 20 attached to the moving object 2. The acquisition unit 500 may also have a function of acquiring the remaining tread depth, which is driving information. Note that the tire temperature and remaining tread depth, which are tire heat information of the tires 20, are acquired for each of the multiple tires attached to the moving object 2.

[0059] The acquisition unit 500 also has a function of acquiring multiple pieces of route information related to the route traveled by the mobile body 2 in order to support processing of the route of travel of the mobile body 2. The route information is information indicating a route from a first point traveled by the mobile body 2 to a second point different from the first point. The route from the first point to the second point may be a single route, or a series of routes passing through multiple points. The route information also associates heat load information related to heat generated in the tire 20 with the route. The acquisition unit 500 acquires multiple pieces of route information. This multiple pieces of route information will be described later.

[0060] The calculation unit 502 is a functional unit that calculates a degradation index of the tire degradation risk. Specifically, the calculation unit 502 calculates the thermal history or the degree of increase or decrease of the thermal history indicating the degree of change in the thermal history, using the tire thermal information acquired by the acquisition unit 500. The thermal history indicates the change characteristics of the tire temperature measured in chronological order, and the degree of increase or decrease of the thermal history indicates the rate of change of the change characteristics of the tire temperature indicated by the thermal history (the gradient of the thermal history). The degradation index of the tire degradation risk is a prediction result of predicting the degradation state of the tire based on the thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history) and the remaining tread depth acquired by the acquisition unit 500. Specifically, the tire condition of the target tire corresponding to the thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history) and the remaining tread depth of the tire is determined, and the determined tire condition is predicted as the degradation state of the tire. This determination of the tire condition and prediction of the degradation state of the tire is performed using predetermined determination conditions.

[0061] Here, prediction of the deterioration state of a tire and a deterioration index of the risk of tire deterioration will be described. FIG. 7 is a conceptual diagram showing the characteristics of thermal history with respect to tire running for two types of tires that reach different degradation states. FIG. 7 shows the characteristics of thermal history for a tire with a large thermal history slope and a tire with a small thermal history slope. As the thermal history slope increases, the risk of tire degradation increases. That is, a tire with a large thermal history slope has a higher risk of degradation than a tire with a small thermal history slope. Note that the sum of thermal histories can also be applied instead of the thermal history slope. That is, a tire with a large total thermal history has a higher risk of degradation than a tire with a small total thermal history.

[0062] Heat accumulates in the tire 20 as the tire 20 travels, causing separation between the tread and the belt in the tire 20 and the generation of smoke due to the heat. For this reason, it is preferable to identify the tire degradation state before separation or smoke occurs in the tire 20 and reduce the degradation risk. Therefore, in this embodiment, the tire condition of a target tire corresponding to the thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history) and the remaining tread depth of the tire is determined, and the determined tire condition is derived as a degradation index of the tire degradation risk.

[0063] Fig. 8 shows an example of a determination map showing the determination conditions for determining the degradation state of a tire as a degradation index of the degradation risk. The determination map shown in Fig. 8 is stored in advance in table 55T. In the determination map, the degradation state of the tire corresponding to the degree of increase or decrease in the thermal history and the remaining tread depth of the tire is defined in a coordinate space having the degree of increase or decrease in the thermal history (the gradient of the thermal history) on the vertical axis and the remaining tread depth of the tire on the horizontal axis. Note that the vertical axis may be the sum of the thermal history, but in this embodiment, a case where the degree of increase or decrease in the thermal history (the gradient of the thermal history) is applied will be described as an example.

[0064] Specifically, the determination map is classified into small regions A, B, and C that indicate the tire degradation risk. The tire degradation risk can be a thermal risk. That is, the small region A is a region to which the tire 20 with the highest thermal risk belongs, and is a region to which the tire 20 with the possibility of thermal degradation (e.g., smoke failure) in which smoke is generated as an example of thermal degradation such as a sudden thermal failure belongs. The small region B is a region to which the tire 20 with a medium degradation risk (thermal risk) belongs, and is a region to which the tire 20 with the possibility of thermal degradation (e.g., separation failure) in which peeling occurs inside the tire 20 belongs, although the tire 20 does not generate smoke belongs. The small region C is a region to which the tire 20 with an even lower degradation risk (thermal risk) belongs than the small regions A and B. For example, the small region C is a region to which the tire 20 with the possibility of thermal degradation (e.g., separation failure) in which peeling occurs inside the tire 20 belongs, and is a region to which the tire 20 with an ordinary degradation risk belongs. These small regions are classified using thresholds R1, R2, and R3 as boundaries that classify the range of the remaining tread depth of the tire into multiple categories, and thresholds th1 and th2 as boundaries that classify the range of the increase / decrease in thermal history (the gradient of thermal history) into multiple categories.

[0065] The thresholds R1, R2, and R3 can be determined using a first value Ra determined from a predetermined value (e.g., an upper limit) of the remaining tread depth at which smoke is predicted to occur in the tire 20, and a second value Rb determined from a predetermined value (e.g., an upper limit) of the remaining tread depth that is greater than the first value Ra and at which peeling is predicted to occur in the tire 20. The thresholds th1 and th2 can be determined using a predetermined value (e.g., an upper limit) of the degree of increase or decrease in thermal history (the slope of the thermal history) in a tire in a normally deteriorated state as described above, and a predetermined value (e.g., a lower limit) of the degree of increase or decrease in thermal history (the slope of the thermal history) in a deteriorated tire in a deteriorated state in which smoke is predicted to occur in the tire 20.

[0066] Therefore, in the determination map, these small regions of the same type are organized, and a region consisting only of small region A is defined as region ErA. Similarly, a region consisting only of small region B is defined as region ErB, and a region consisting only of small region C is defined as region ErC. Note that it is also possible to set a region ErAB that combines regions ErA and ErB as a region where there is a high possibility that smoke will be generated in the tire 20 or peeling will occur inside the tire 20.

[0067] Therefore, the calculation unit 502 uses the determination map (FIG. 8) to determine the tire deterioration state of the target tire from the tire's thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history) and the remaining tread depth of the tire, and derives the determined tire deterioration state as a deterioration index of the tire deterioration risk. That is, the calculation unit 505 derives, for the target tire 20, any of the deterioration indexes KA, KB, and KC corresponding to the regions ErA, ErB, and ErC (and may further include the region ErCe) shown in the determination map (FIG. 8). Note that the above-mentioned predetermined value and threshold value are not limited to those mentioned above, and may be within a predetermined range, or multiple values ​​may be set in stages.

[0068] The deterioration index of the deterioration risk is not limited to being calculated by the calculation unit 502 described above. For example, it may be manually input by a user. Furthermore, the tire heat information acquired by the acquisition unit 500 may be applied as the deterioration index of the deterioration risk. In this case, the calculation unit 502 is not necessarily required and may be omitted.

[0069] The above-mentioned deterioration index may be derived for each tire 20 mounted on the moving body 2, or a deterioration index of a representative tire in the moving body 2 may be applied. Since the deterioration risk of the tires 20 on the moving body 2 increases in the order of tires belonging to region ErC, region ErB, and region ErA, the deterioration risk increases in the order of deterioration indexes KC, KB, and KA (KA>KB>KC). For this reason, the deterioration index of the tire with the highest deterioration risk among the tires 20 mounted on the moving body 2 may be used as the deterioration index of the tires of the moving body.

[0070] The control unit 504 is a functional unit that determines the route of the moving body 2 based on the deterioration index of the deterioration risk (the deterioration state of the target tire) calculated by the calculation unit 502 and the route information acquired by the acquisition unit 500.

[0071] Here, the route information will be described. As described above, the route information is information in which thermal load information regarding heat generated in the tire 20 is associated with the route.

[0072] Fig. 9 is a diagram showing an example of route information. The route information shown in Fig. 9 is stored in advance in table 55T as a database. The route information is registered as a record in which a travel condition as heat load information is associated with each route indicating a route.

[0073] In the example shown in FIG. 9, a route from a first point to a second point is shown as a connection of nodes N as a route indicating a path. For example, when the first point is node N01 and the second point is node N11, the route indicating the path is shown as "N01-N11". A route indicating a path is associated with a predetermined traveling condition of the moving object 2. In the example shown in FIG. 9, each of distance L, speed V, elevation difference H, and temperature change T is applied as a traveling condition. Distance L indicates the distance between nodes. Speed ​​V indicates the speed of the moving object 2 traveling between nodes. Elevation difference H indicates the elevation difference, which is the difference in altitude between nodes. Temperature change T corresponds to the magnitude of heat generated in the tire 20 and indicates the temperature change of the tire 20 when the moving object travels between the nodes. This temperature change T can be classified based on the magnitude of heat generated in the tire, for example, in order of the magnitude of heat generated in the tire, that is, in order of the magnitude of the temperature change.

[0074] In this embodiment, the temperature change T can be classified into temperature changes corresponding to three types of heat levels: a first heat level, a second heat level, and a third heat level. Specifically, the first heat level is a heat level where the temperature change is less than the first threshold value. The second heat level is a heat level where the temperature change is greater than that of the first heat level and less than the second threshold value (i.e., a temperature change that is equal to or greater than the first threshold value and less than the second threshold value). The third heat level is a heat level where the temperature change is greater than that of the second heat level (i.e., a temperature change that is equal to or greater than the second threshold value). Therefore, in the first heat level, it is smaller than the value of the temperature change of the second heat level, and in the second heat level, it is smaller than the value of the temperature change of the third heat level (in the example of FIG. 9, it is shown as T01 < T02 < T03). The path (route) due to the temperature change of the first heat level is preferably applied to the degradation index KA, the path (route) due to the temperature change of the second heat level is preferably applied to the degradation index KB, and the path (route) due to the temperature change of the third heat level is preferably applied to the degradation index KC.

[0075] The control unit 504 extracts the path information corresponding to the degradation index (any one of KA, KB, KC) of the degradation risk, which is calculated by the calculation unit 502, using the plurality of path information (FIG. 9) acquired by the acquisition unit 500. The plurality of path information will belong to a path group based on the common degradation index of the degradation risk by being classified into each of the degradation indexes of the degradation risk. Based on this extracted path information, the path of the moving body 2 is determined. Specifically, for the traveling path from the starting point to the ending point, the path according to the extracted path information is determined. For this determination, a path with the minimum temperature change among the corresponding heat levels may be selected, or a path where at least one of the distance L, speed V, height difference H, and temperature change T becomes an optimal value (for example, the minimum value) may be selected.

[0076] FIG. 10 is a conceptual diagram showing an example of a route of a moving object 2 determined based on the deterioration index of deterioration risk and route information. In the figure, a node N is shown within the node diagram showing each point. In addition, in order to express the points (nodes) of work sites such as a quarrying site and a mine in three dimensions, the directions intersecting the horizontal direction are shown by the X- and Y-axis, and the height direction is shown by the Z-axis. In the figure, the route of the moving object 2 with the deterioration index KA of the deterioration risk is shown by a solid line, the route with the deterioration index KB is shown by a dashed line, and the route with the deterioration index KC is shown by a dotted line.

[0077] 10, the route taken by a mobile unit 2 with a degradation indicator KA, which has a high degradation risk, is determined to be a route that includes nodes N01-N11-N22-N31-N41. Also, the route taken by a mobile unit 2 with a degradation indicator KB is determined to be a route that includes nodes N01-N12-N23-N41. Similarly, the route taken by a mobile unit 2 with a degradation indicator KC is determined to be a route that includes nodes N01-N13-N41.

[0078] In addition, at least one of whether or not the moving body 2 is loaded with goods such as minerals and the load amount can be further added to the above-mentioned traveling conditions. That is, it is possible to further add load information indicating the load on the moving body 2. As an example, at least one of information indicating whether or not goods are loaded and information indicating the load amount can be applied to the load information. The load information is effective in considering that the load applied to the tires changes due to the loading of goods such as minerals on the moving body 2, and the thermal load related to the heat generated in the tires changes.

[0079] The control unit 504 outputs information indicating the route of the moving object 2 indicated by the deterioration index to the user terminal 3. Thus, the user terminal 3 can receive information indicating an appropriate route according to the deterioration state of the tires 20 of the moving object 2. Thus, the user operating the user terminal 3 can instruct an appropriate route according to the deterioration state of the tires of the moving object 2.

[0080] (Information Processing) Next, the information processing executed in the information processing system 1 will be described, focusing on the processing executed in the server 5. The user terminal 3 executes a process of measuring tire heat information, and transmits the data to the server 5. The user terminal 3 then waits for a response from the server 5. The user terminal 3 receives the response from the server 5, i.e., information indicating the route of the moving object 2, and controls output of the received information, such as displaying it on the display unit 33. This information indicating the route of the moving object 2 makes it possible to formulate a travel plan for the moving object 2. Note that the planning of the travel plan for the moving object 2 may be executed by the server 5 or may be executed by the user terminal 3.

[0081] Fig. 11 is a flowchart showing an example of the flow of server processing executed in the server 5. The processing routine shown in Fig. 11 is an example of the flow of processing of the server program 55P stored in the server 5. The processing routine shown in Fig. 10 is executed by the CPU 50A in the server 5.

[0082] The information processing shown in FIG. 11 is an example of processing executed by an information processing method and an information processing program according to the present disclosure.

[0083] As described above, in step S100, the CPU 50A as the acquisition unit 500 executes the process of acquiring data based on tire heat information (temperature data) transmitted from the user terminal 3. In step S100, it is possible to acquire data based on driving information (remaining tread depth).

[0084] In step S100, in order to support processing for the route along which the moving object 2 will travel, the above-mentioned plurality of pieces of route information (FIG. 9) are acquired.

[0085] Next, in step S110, the CPU 50A, as the calculation unit 502, executes a process of calculating the degradation index of the tire degradation risk described above. That is, as described above, the tire heat information is used to calculate the thermal history or the degree of increase or decrease in the thermal history indicating the degree of change in the thermal history. The degradation index of the tire degradation risk is a prediction result of predicting the degradation state of the tire based on the thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history) and the remaining tread depth of the tire.

[0086] Next, in step S120, the CPU 50A, as the control unit 504, executes a process of determining a route for the moving object 2 based on the deterioration index (KA, KB, or KC) of the deterioration risk calculated in step S110 and the route information acquired in step S100. Specifically, using a plurality of route information (FIG. 9), route information corresponding to the deterioration index (KA, KB, or KC) of the deterioration risk is extracted. Based on this extracted route information, the route for the moving object 2 is determined (FIG. 10). In step S120, a process of outputting information indicating the route for the moving object 2 indicated by the deterioration index to the user terminal 3, i.e., a process of transmitting the information to the user terminal 3, is performed, and this processing routine is terminated.

[0087] Therefore, the user terminal 3 can receive information indicating an appropriate route depending on the deterioration state of the tires 20 of the moving object 2. Therefore, the user operating the user terminal 3 can appropriately indicate an appropriate route depending on the deterioration state of the tires of the moving object 2.

[0088] In this way, according to the information processing system 1 of the present disclosure, by taking into consideration the deterioration state determined according to the heat generated in the tire, it is possible to determine the optimal route for the travel of the mobile object on which the tire is mounted.

[0089] In the above, a case has been described in which the optimal route for the travel of a moving object is determined using predetermined route information. However, in a work site such as a quarrying site or a mine, the terrain changes from moment to moment as the work progresses. For this reason, if the predetermined route information is always used, it is difficult to determine the route of a moving object traveling in an actual work site. Therefore, in this embodiment, a process can be executed that enables the route information to be updated according to the ever-changing terrain.

[0090] As described above, a process that allows route information to be updated to accommodate changing terrain will now be described.

[0091] Fig. 12 is a conceptual diagram showing an example of a route of a moving object 2 determined based on the deterioration index of deterioration risk and route information while updating the route information according to the changing terrain. In Fig. 12, the route of the moving object 2 with the deterioration index KA of the deterioration risk shown in Fig. 10 is shown by a solid line. Fig. 12 also shows a case where the point shown by node N22 no longer exists due to mining or the like.

[0092] In the example shown in Fig. 12, since node N22 no longer exists, a process is executed to delete from the database (table 55T) the records corresponding to the route information indicating the route from node N11-N22 to node N22-N31. The process to delete the route information corresponding to the fact that node N22 no longer exists may be executed by the above-mentioned control unit 504. Specifically, the control unit 504 acquires information indicating that node N22 no longer exists, and executes a process to delete the records including the corresponding node from the database stored as table 55T. In Fig. 12, the route information corresponding to the deleted records is indicated by dotted lines.

[0093] On the other hand, since node N22 no longer exists, the route information for the nodes connected to node N22, for example, the routes to nodes N11 and N31, will be different. Therefore, the route information for the nodes connected to the node that no longer exists is updated. When the traveling conditions of the moving object change due to node N22 no longer existing, the route information can be updated by updating the traveling conditions of the corresponding route according to the changing traveling conditions of the moving object. Specifically, the control unit 504 acquires information corresponding to the traveling conditions of the moving object that will change when node N22 no longer exists, and executes a process of updating the database record stored as table 55T for the corresponding route information.

[0094] FIG. 12 shows a case where, when node N22 no longer exists, a route indicating the path of nodes N01-N11-N21-N31-N41 is determined as the route for the moving object 2 with the deterioration indicator KA.

[0095] In the above, a case has been described in which route information is deleted by deleting a record when a point that is a node no longer exists, and related route information is updated, but this is not limited to deleting route information and updating related route information. For example, the same applies when driving conditions change on a route between nodes. Similarly, when a new node that is a point is added as the work progresses, an addition process can be applied instead of deletion.

[0096] In this way, even if a node point disappears, a node point is added, or the driving conditions along the route change, the route information can be updated appropriately. Therefore, even if the topography changes from moment to moment as work progresses at a work site such as a quarrying site or a mine, it is possible to determine an appropriate route.

[0097] (Modification) In the above embodiment, a case has been described in which an optimal route for the travel of a moving body is determined in consideration of a deterioration state determined according to heat generated in a tire, but the technology disclosed herein is not limited to determining a route. For example, instead of controlling to determine a route, the information processing device may output information to an external device or to display information on a display unit such as the display unit 33 or 53. In addition, after performing control to determine a route, the information processing device may perform control to output information indicating the determined route to an external device or to display information on a display unit such as the display unit 33 or 53.

[0098] Specifically, the above-mentioned control unit 504 may be configured to include a functional unit that functions as an output unit. Specifically, the control unit 504 may output information about the route associated with the thermal load information corresponding to the tire heat information based on the deterioration index of the deterioration risk (the deterioration state of the target tire) and the route information. Examples of information that may be applied to the information about the route include information indicating the route itself, deterioration risk that is thermal load information associated with the information indicating the route, and tire life-related information such as the usable period (life) of the tire, such as the drivable distance. The user terminal 3 receives the output of the information about the route and displays the information on the display unit 33, allowing the user to confirm the information.

[0099] In this way, for example, when a route is displayed, it is possible to display tire life-related information such as the risk of deterioration (e.g., risk of breakdown) when the route is selected, and the usable period (life) of the tire, such as the mileage that can be traveled. Therefore, the user can select a route while checking the displayed information, and the process related to the travel of the moving object 2 can be supported.

[0100] Moreover, the above-mentioned moving body 2 can be applied to a moving body that runs by manual operation of an operator and a moving body capable of automatic running. An example of a moving body that can run automatically is a moving body that can run autonomously or follow autonomously, and for example, a moving body that runs automatically according to a specified route can be applied. When the technology of the present disclosure is applied to a moving body that can run automatically, the control unit 504 may be configured to provide information on the determined route to the moving body 2 as described above. That is, the control unit 504 may be configured to include a providing unit that provides information on the route to the moving body 2. Furthermore, the moving body 2 may control the running of the moving body 2 so that the moving body 2 runs according to the route based on information indicating the route provided from the control unit 504 as the providing unit. When the information indicating the route to be provided to the moving body 2 described above is provided from outside the moving body 2, information indicating the route may be generated outside the moving body 2 and provided to, for example, an automatic running control device that controls the autonomous running of the moving body 2. In addition, when deriving a route for the moving body 2, for example, an automatic driving control device that controls the autonomous driving can generate information indicating the route, and the automatic driving control unit can control the moving body to autonomously drive according to that route.

[0101] In this way, the moving object 2 can automatically travel the optimal route derived in accordance with the heat generated in the tires.

[0102] (Other embodiments) The above-mentioned user terminal 3 and server may be a common device. In the above, data from the user terminal 3 is transmitted to the server 5, and the server 5 returns information indicating the response to the user terminal 3, but the function of the user terminal 3 may be installed in an on-board device of the moving object 2. In this way, it becomes possible for the moving object 2 to check the route of the moving object 2.

[0103] Although the technology of the present disclosure has been described above using the embodiments, the technical scope of the technology of the present disclosure is not limited to the scope described in the above embodiments. Various modifications or improvements can be made to the above embodiments without departing from the gist of the technology, and the forms with such modifications or improvements are also included in the technical scope of the technology disclosed.

[0104] In the above embodiment, the processing is performed by executing the program stored in the auxiliary storage device, but at least a part of the processing of the program may be realized by hardware. The flow of the processing of the program described in the above embodiment is also an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed without departing from the scope of the invention.

[0105] Furthermore, in order to cause a computer to execute the processing in the above-described embodiment, a program describing the above-described processing in code that can be processed by a computer may be stored on a storage medium such as an optical disk and distributed.

[0106] In the above-described embodiment, a CPU has been used as an example of a general-purpose processor. However, in the above-described embodiment, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0107] Furthermore, the operations of the processors in the above-described embodiments may not only be performed by a single processor, but may also be performed by multiple processors working together, or may be performed by multiple processors located at physically separate locations working together.

[0108] All publications, patent applications, and standards mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent application, or standard was specifically and individually indicated to be incorporated by reference.
