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 a 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 supporting the operation of the moving body regarding the travel of the moving body on which the tires are mounted. Also, for example, when controlling a vehicle using an Autonomous Haulage System (AHS), it is necessary to take into consideration the heat generated in the tires.

[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 is a diagram showing a schematic configuration of an information processing system 1. As shown in FIG. 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 including 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] The moving object 2 travels from a first point, which is a point from the current location to a 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 temperature of 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. For this reason, it is preferable to consider the temperature of the tires for each route along which the moving object 2 travels. Therefore, in this embodiment, the heat generated in the tires is considered for each route along which the moving object 2 travels (details will be described later). The information indicating the heat generated in the tires to be considered is tire heat state information indicating the state related to the heat of the tires on the route, and tire temperature increase / decrease information indicating the amount of increase / decrease in the temperature of the tires that increases / decreases during travel can be applied.

[0035] 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.

[0036] The tire temperature increase / decrease information is a physical quantity indicating an increase or decrease in tire temperature that changes in a tire traveling along 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.

[0037] <Mobile object> Fig. 2 is a conceptual diagram showing an example of a moving object 2 such as a vehicle traveling in a mine. The example shown in Fig. 2 conceptually shows a configuration including an on-board device 24 that collects tire heat information and the like.

[0038] 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.

[0039] 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.

[0040] The moving object 2 is equipped with an on-board device 24 that collects and transmits information related to tires (including at least tire temperature data 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] FIG. 3 is a cross-sectional view showing an example of the structure of a tire 20. As shown in FIG. 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 such as a measuring device or a sensor module 22.

[0046] <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 is a diagram showing an example of the configuration of the user terminal 3. As shown in FIG. 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.

[0047] 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.

[0048] 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.

[0049] In addition, the auxiliary storage device 35 stores various data 35D used by the user terminal 3.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] <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 (for example, tire temperature) from the user terminal 3 and transmitting information to assist 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. In addition, a communication unit 51 that communicates with devices on the network 6, an input unit 52 for inputting data by a 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The acquisition unit 500 also has a function of acquiring multiple pieces of route information related to the route along which the moving object 2 travels, in order to support processing of the route along which the moving object 2 travels. The route information is information indicating a route along which the moving object 2 travels from a first point to a second point different from the first point. The route information may include information related to the route, such as elevation difference, distance, and road surface conditions. Note that the route from the first point to the second point may be a single route, or may be a series of routes passing through multiple points.

[0059] Furthermore, the acquisition unit 500 has a function of acquiring designated values ​​related to a plurality of parameters (parameter information) that indicate driving conditions related to the driving of the moving object along the route input by the user. One example of the plurality of parameters is a value that associates at least one of the tire temperature, the load (i.e., the load) of the moving object, the driving speed, the outside air temperature, and the tire internal pressure with the route (FIG. 8). It is possible to omit the parameters of the outside air temperature and the tire internal pressure from the plurality of parameters.

[0060] The calculation unit 502 is a functional unit that calculates a tire state related to tire heat (tire heat state information). Specifically, the calculation unit 502 calculates tire heat state information and tire temperature increase / decrease information for each path as tire temperature fluctuation information, using tire heat information including the tire temperature acquired by the acquisition unit 500, path information, and designated values ​​related to a plurality of parameters. The tire temperature increase / decrease information is information including at least one of an increase amount of the tire temperature and an decrease amount of the tire temperature.

[0061] The tire temperature increase / decrease information for each route calculated by the calculation unit 502 is a prediction result of the increase / decrease in tire temperature when the moving body travels along a route based on the route information acquired by the acquisition unit 500. The prediction of the tire temperature increase / decrease information for each route, i.e., the prediction of the tire temperature and the like along the route along which the moving body travels, will be described later.

[0062] The control unit 504 is a functional unit that performs control to output the predicted tire temperature increase / decrease information for each route calculated by the calculation unit 502 to the user terminal 3 or the display unit 53. The acquisition unit 500 is an example of an acquisition unit of the present disclosure, the calculation unit 502 is an example of an estimation unit of the present disclosure, and the control unit 504 is an example of a display control unit of the present disclosure. In addition, a functional unit in the calculation unit that predicts the tire temperature or the like is an example of a prediction unit of the present disclosure.

[0063] Here, prediction of tire temperature increase / decrease information as tire heat state information will be described.

[0064] Heat accumulates in the tire 20 as the tire 20 travels, which can cause problems such as separation between the tread and the belt in the tire 20 and smoke due to heat. Since such problems are caused by increases and decreases in tire temperature, this embodiment makes it possible to assist in avoiding the above problems by having the vehicle confirm increases and decreases in tire temperature. Specifically, this embodiment provides information for driving the vehicle so as to reduce increases in tire temperature.

[0065] FIG. 7 is a diagram showing a schematic diagram of a route (travel route) along which a moving object travels in a work site such as a quarry site or a mine. At the work site, the mobile object is loaded with cargo such as excavated crushed stone and unloaded at a predetermined base. In Fig. 7, the base where the cargo is loaded is indicated as node L, the base where the cargo is unloaded is indicated as node D, and the route between the base where the cargo is loaded (node ​​L) and the base where the cargo is unloaded (node ​​D) is indicated as route R.

[0066] When a moving body travels along a route, the tire temperature increases or decreases depending on the traveling state of the moving body. That is, the tire temperature changes depending on the parameter values ​​such as the tire temperature, the load of the moving body, the traveling speed, the outside air temperature, and the tire internal pressure. Meanwhile, the values ​​of these parameters change from moment to moment. On each route, when the parameter values ​​change, the amount of increase or decrease in the tire temperature also changes. Therefore, in this embodiment, the user is configured to be able to specify the values ​​of multiple parameters indicating the traveling state as designated values. Thus, the user can check the increase or decrease in tire temperature for each route when the parameter values ​​are changed.

[0067] FIG. 8 is a conceptual diagram showing a user interface that allows a user to specify a parameter value as a specified value. The user interface 320 shown in FIG. 8 includes a display area 322 that displays the names of parameters indicating the driving state, a display area 324 that displays the parameter values ​​so that they can be specified, and a display area 326 that displays the parameter values ​​specified in the display area 322. In the example shown in FIG. 8, tire temperature, the load of the moving body, the driving speed, the outside air temperature, and the tire pressure are applied as examples of parameters indicating the driving state displayed in the display area 322. The parameter values ​​of these parameters can be changed by sliding a toggle 324T. The specified parameter values ​​are then displayed in the display area 326. These parameters are also associated with a route. In FIG. 8, the display area that displays the route so that it can be specified includes a selection button 324S that allows a user to select one of a plurality of routes in a pull-down format, and a text box 324R that displays information indicating the selected route. The information indicating the route includes at least one of the driving distance of the moving body and the elevation difference. Therefore, the user interface 320 can change the conditions when predicting tire temperature increase / decrease information for each route, which will be described later.

[0068] The initial values ​​of each parameter in the user interface 320 may be values ​​detected in the current moving object, or may be predetermined values.

[0069] The user interface 320 may be provided as one of the functions of the acquisition unit 500 . Moreover, the user interface 320 is an example of a designation unit of the present disclosure.

[0070] The user interface 320 is an example of a configuration capable of specifying a parameter value, and is not limited to the form shown in FIG. 8, as long as it includes a module that enables the parameter value to be specified and confirmed. For example, a previously specified numerical value may be acquired and the acquired numerical value may be designated as the parameter value. An example of acquiring the numerical value is acquiring a numerical value inputted by the input unit 32 through a user operation. Thus, it becomes possible to designate a parameter indicating a running state as a parameter-based condition based on a numerical value intended by the user. Another example of acquiring the numerical value is storing one or more parameter conditions based on at least one parameter value in a memory (such as the auxiliary storage device 35) in advance, and acquiring the numerical value by reading out the recorded parameter value from the memory. Specifically, a parameter condition in which the parameter value is specified more frequently than the standard frequency is stored in a memory in advance, and by reading out the parameter condition, it is possible to confirm the value of each parameter without selecting it each time. Examples of such parameter conditions include a heavy load parameter condition (high load condition) indicating a heavier load or faster speed than the standard, and a heavy load parameter condition (low load condition) indicating a lighter load or slower speed than the standard.

[0071] The calculation unit 502 predicts the increase or decrease in tire temperature when the moving body travels along each route as tire temperature increase or decrease information for each route, based on the parameter values ​​specified through the user interface 320. That is, the prediction of tire temperature can be realized as a prediction process executed in the calculation unit 502.

[0072] Here, a process for predicting the tire temperature, which increases or decreases when a moving body travels along a route, will be described.

[0073] The prediction process in the calculation unit 502 uses a trained learning model to estimate and output, for each route, an unknown tire temperature increase or decrease amount corresponding to the parameter value specified by the user interface 320. The learning model is trained using learning data including the parameter values ​​indicating the driving state when each route is traveled and the tire temperature increase or decrease amount for the parameters.

[0074] Next, a learning process for generating a learning model will be described. In the learning process, learning is performed using the values ​​(input data) of each parameter, whose label is the amount of increase or decrease in tire temperature (output data) for the parameter value indicating the driving state when each route is traveled, as learning data (so-called teacher data). In other words, the learning model is trained to output the amount of increase or decrease in tire temperature for the parameter value indicating the driving state of the input route.

[0075] 9 is a diagram showing a conceptual configuration of a learning model generation device that generates a learning model 502M. The learning model generation device includes a learning processing unit 502P. The learning model generation device can be configured to include a computer that includes a CPU (e.g., CPU 50A of the server 5) not shown, and is executed as the learning processing unit 502P by processing executed by the CPU to generate the learning model 502M.

[0076] The learning data used to generate the learning model 502M is a large collection of sets of data indicating parameter values ​​that indicate the driving conditions when traveling each route, and data indicating the amount of increase or decrease in tire temperature corresponding to those parameter values.

[0077] Therefore, the learning data is a set of data indicating the values ​​of parameters indicating the driving conditions when each route is driven and data indicating the amount of increase or decrease in tire temperature corresponding to the parameter values. An example of the learning data is shown in Table 1 below. Table 1 is an example of a data set in which data (r) indicating the values ​​of parameters indicating the driving conditions is associated with data (R) indicating the amount of increase or decrease in tire temperature as learning data.

[0078] [Table 1]

[0079] The learning model is a learning model 502M that is generated by a learning processing unit 502P of the learning model generating device shown in FIG. 9 using the above-mentioned learning data.

[0080] The learning processing unit 502P has a function of outputting the tire temperature increase / decrease amount in consideration of the interrelationships between the input values ​​of multiple parameters. That is, the learning processing unit 502P has a function of generating a learning model that receives the values ​​of multiple parameters as input and outputs the tire temperature increase / decrease amount corresponding to the values ​​of the multiple parameters.

[0081] The learning processing unit 502P can be configured, for example, by a known neural network (NN) including an input layer, an intermediate layer, and an output layer. The neural network includes a large number of node groups (neuron groups) having inter-node connections and feedback connections in each layer. Input data is output via the input layer, intermediate layer, and output layer.

[0082] The learning processing unit 502P can generate tire temperature increase / decrease amounts corresponding to the multiple parameter values ​​by learning using the values ​​of many parameters. That is, the data generated in the learning processing unit 502P is compared with the tire temperature increase / decrease amounts of the learning data, and the connections between all nodes, that is, each of the weight parameters of the connections between nodes, are optimized using a method such as the gradient descent method or the error backpropagation method so as to minimize the error of the comparison result. Note that the neural network is a known technology, so a detailed description will be omitted.

[0083] As described above, the learning processing unit 502P generates the learning model 502M by the learning model generation process using the above-mentioned learning data. The learning model 502M is expressed as a collection of information on weight parameters (weights or strengths) of connections between nodes as a result of learning, and is stored in a memory (not shown, for example, the ROM 30C or the auxiliary storage device 35 of the server 5).

[0084] In the process of the learning processing unit 502P described above, a set of data on parameters of the running state and data on the tire temperature increase / decrease amount is acquired as learning data, and the learning model 502M is generated using the acquired learning data. That is, a set of information on weight parameters (weights or strengths) of bonds between nodes of the learning result learned using a large number of learning data as described above is obtained. Then, data expressed as a set of information on weight parameters (weights or strengths) of bonds between nodes of the learning result is stored as the learning model 502M. Then, the calculation unit 502 uses the learned learning model 502M (i.e., data expressed as a set of information on weight parameters of bonds between nodes of the learning result) as the learning model 502M. If a sufficiently trained learning model 502M is used, it is not impossible to predict (estimate) the amount of increase or decrease in tire temperature from the parameters of any driving state.

[0085] Therefore, the calculation unit 502 uses the above-mentioned learning model 502M to predict the tire temperature increase or decrease along each route traveled by the moving object as tire temperature increase or decrease information corresponding to the parameter value for each route specified by the user interface 320. That is, the calculation unit 502 inputs the parameter value for each route specified by the user interface 320 to the learning model 502M, and obtains the tire temperature increase or decrease amount, which is the output of the learning model 502M, as a prediction result.

[0086] Fig. 10 is a conceptual diagram showing the tire temperature increase / decrease amount predicted for each route according to the parameter value specified by the user. Fig. 10 is an example of display data resulting from control performed by the above-mentioned control unit 504 to display data, which is the prediction result of tire temperature increase / decrease information for each route calculated by the calculation unit 502, on the display unit 33 of the user terminal 3 or the display unit 53 of the server 5. In other words, the control unit 504 generates display data and performs control to output it to the user terminal 3 or the display unit 53.

[0087] The display data shown in Fig. 10 is an example including a display form in which tire temperature increase / decrease information for each route is shown as a bar graph, and a display form in which cycle time for each route is shown as a bar graph. Tire temperature increase / decrease information is distributed in the plus (+) direction when tire temperature increases, and is distributed in the minus (-) direction when tire temperature decreases. The cycle time indicates the travel time between bases. In each display form in the figure, data for a state in which no cargo is loaded (unloaded state) is shown as a single-colored bar graph, and data for a state in which cargo is loaded (loaded state) is shown as a bar graph filled with diagonal lines.

[0088] Therefore, by changing the parameter value in the above-mentioned user interface 320, the tire temperature increase / decrease information and cycle time for each route corresponding to the changed parameter value are changed and reflected in the bar graph. That is, the parameter value of the user interface 320 (FIG. 8) and the height of the bar graph (FIG. 10) are linked. Therefore, by the user specifying the parameter value indicating the driving state for each route to change the condition, it becomes possible for the user to confirm the tire temperature increase / decrease information and the like corresponding to the changed (specified) driving state.

[0089] The display data is not limited to the tire temperature increase / decrease information for each route and the cycle time for each route shown in Fig. 10, and may be, for example, only the tire temperature increase / decrease information for each route. Also, the display form is not limited to a bar graph, and any display form may be adopted as long as it allows confirmation of the tire temperature increase / decrease information and changes in the cycle time.

[0090] (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.

[0091] In the user terminal 3, a process of measuring the tire temperature (tire heat information) is executed, and the data is transmitted to the server 5. Then, the user terminal 3 waits for a response from the server 5. The user terminal 3 receives a response from the server 5, for example, 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. In addition, the user terminal 3 can control to receive information of the above-mentioned user interface 320 as a response from the server 5 and display it on the display unit 33 (FIG. 8). The user can specify the value of a parameter for each route using the user interface 320 displayed on the user terminal 3. When the value of a parameter for each route is specified, the user terminal 3 can transmit the specified value of the parameter for each route to the server 5.

[0092] 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. 11 is executed by the CPU 50A in the server 5.

[0093] 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.

[0094] As described above, the CPU 50A as the acquiring unit 500 executes a process of acquiring data (temperature data) based on tire heat information transmitted from the user terminal 3 in step S100. Also, in step S100, a process of acquiring data indicating parameter values ​​for each route specified using the user interface 320 is also executed. Furthermore, in step S100, information indicating a plurality of routes along which the moving object 2 travels (e.g., FIG. 7) is acquired.

[0095] Next, in step S110, the CPU 50A, as the calculation unit 502, executes a process of predicting the tire temperature increase or decrease when the moving object travels along each route as tire temperature increase or decrease information for each route, based on the parameter values ​​specified via the above-mentioned user interface 320. In the prediction process, the prediction result of the tire temperature for each route is obtained using the above-mentioned learning model 502M.

[0096] Next, in step S120, the CPU 50A, as the control unit 504, executes a process of controlling output of tire temperature increase / decrease information (amount of tire temperature increase / decrease) for each route, which is the prediction result of the tire temperature for each route calculated in step S110, to the user terminal 3 or the display unit 53. In step S120, the tire temperature increase / decrease information (amount of tire temperature increase / decrease) shown for each route is generated as data in a predetermined display form (for example, FIG. 10), and output (i.e., transmit) it to the user terminal 3, and then this processing routine ends.

[0097] Therefore, the user terminal 3 can receive tire temperature increase / decrease information for each route traveled by the moving object 2. Therefore, the user operating the user terminal 3 can confirm tire temperature increase / decrease information (amount of tire temperature increase / decrease) for each route traveled by the moving object 2. Therefore, the user can indicate an appropriate route according to the confirmed tire temperature increase / decrease information (amount of tire temperature increase / decrease), indicate the traveling state of the moving object 2, or instruct the moving object 2 to stop traveling.

[0098] In this manner, according to the information processing system 1 of the present disclosure, information on heat generated in the tires when a moving body equipped with the tires is traveling can be estimated in correspondence with the route. That is, in this embodiment, tire temperature increase / decrease information for each route corresponding to the traveling state (parameter) specified by the user is output so that the user can check it. This allows the user to specify the traveling state of the moving body 2 for each route, check the heat (amount of tire temperature increase / decrease) generated in the tires mounted on the moving body 2, and determine a plan for the traveling of the moving body 2 at the work site where the moving body 2 travels. That is, according to the information processing system 1 of the present disclosure, it is possible to support the operation of traveling of the moving body 2 traveling at a work site such as a quarrying site or a mine.

[0099] In the above, a case has been described in which tire temperature increase / decrease information for each route of a moving object is output so that the user can check it 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 terrain that changes from moment to moment.

[0100] For example, when the terrain changes as the work progresses, the base and route described above may be changed according to the change in terrain. Specifically, when a base node no longer exists, the no longer existing node may be used as a relay point on the route, or the no longer existing node may be deleted and the routes of other nodes connected thereto may be deleted. In addition, when a new base or route is added, a node and route indicating the added base may be added.

[0101] In this way, even if bases or routes no longer exist or are added, it is possible to appropriately update the bases and routes. Therefore, even if the terrain changes from moment to moment as work progresses at a work site such as a quarrying site or a mine, it is possible to output tire temperature increase / decrease information for each route so that the user can check it.

[0102] In the above, an example of outputting tire temperature increase / decrease information for each route so that the user can confirm it has been described. However, the tire 20 accumulates heat as it travels, which may cause problems such as separation between the tread and the belt in the tire 20 or smoke due to heat. In this embodiment, it is possible to consider the risk of tire deterioration including tire components that may cause the problem. Specifically, in this embodiment, it is possible to output a degradation index of the tire degradation risk that may cause a problem together with or instead of the tire temperature increase / decrease information.

[0103] That is, the tire heat information can be applied with a heat history indicating the tire heat that changes from moment to moment. The heat history indicates the change characteristic of the tire temperature shown in a time series, and can be calculated, for example, by integrating the tire temperature shown in a time series with the tire running time or the like. The heat history can correspond to the degree of deterioration of the tire including the tire constituent members. The tire heat information and the heat history can be used as an example of an index for predicting the risk of deterioration of the tire including the tire constituent members.

[0104] Specifically, a function for calculating a degradation index of tire degradation risk can be added to the above-mentioned calculation unit 502. That is, the calculation unit 502 calculates the thermal history or the degree of increase or decrease in the thermal history indicating the degree of change in the thermal history, using the tire heat information acquired by the acquisition unit 500 and the calculated tire heat state information. The degradation index of 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). It is possible to calculate the degradation index of tire degradation risk by adding the remaining tread depth of the tire.

[0105] The calculation unit 502 judges the tire condition of the target tire indicated by the thermal history or the degree of increase or decrease of the thermal history (the gradient of the thermal history), and predicts the judged tire condition as the deterioration state of the tire. This judgment of the tire condition and prediction of the deterioration state of the tire are performed using a judgment condition determined in advance.

[0106] FIG. 12 is a conceptual diagram showing the characteristics of thermal history with respect to tire running. FIG. 12 shows the characteristics of thermal history of 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. 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 be applied instead of the thermal history slope. In other words, a tire with a large total thermal history has a higher risk of degradation than a tire with a small total thermal history.

[0107] 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 deterioration state before separation or the generation of smoke in the tire 20, thereby reducing the risk of deterioration. Therefore, the tire condition of the target tire is determined based on the thermal history or the degree of increase or decrease in the thermal history (the gradient of the thermal history), and the determined tire condition is derived as a deterioration index of the tire deterioration risk.

[0108] Fig. 13 shows an example of a determination map showing the determination conditions for determining the tire degradation state as a degradation index of the degradation risk. The determination map shown in Fig. 13 is stored in advance in table 55T. In the determination map, the degradation state of the tire corresponding to the degree of increase / decrease in the thermal history and the remaining tread depth of the tire are defined in a coordinate space having the degree of increase / 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.

[0109] As shown in FIG. 13, 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 a normal level of tire degradation risk (normal failure) belongs, and is a region to which the tire 20 with the possibility of deterioration due to use or aging 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.

[0110] 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.

[0111] 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.

[0112] Therefore, the calculation unit 502 uses the determination map (FIG. 13) to determine the degradation 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 degradation state of the tire as a degradation index of the tire degradation risk. That is, the calculation unit 505 derives degradation indexes for the target tire 20 corresponding to the regions ErA, ErB, and ErC (and may further include region ErCe) shown in the determination map (FIG. 13). Note that the above-mentioned predetermined values ​​and thresholds are not limited to those mentioned above, and may be within a predetermined range, or multiple values ​​may be set in stages.

[0113] The deterioration index of the deterioration risk is not limited to being calculated by the above-mentioned calculation unit 502. For example, it may be manually input by the user.

[0114] 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 as the value of the deterioration index increases. 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.

[0115] The control unit 504 may have a functional unit that outputs the deterioration index, which indicates the deterioration risk, calculated by the calculation unit 502, in association with the route. The control unit 504 outputs information indicated by the deterioration index for each route to the user terminal 3. Thus, the user terminal 3 can receive information (deterioration index) indicating the deterioration state of the tires 20 of the moving object 2. Thus, the user operating the user terminal 3 can check the deterioration state of the tires of the moving object 2 for each route. Thus, the user operating the user terminal 3 can check and instruct an appropriate route according to the deterioration state of the tires of the moving object 2.

[0116] (Modification) In the above embodiment, tire heat state information (e.g., tire temperature increase / decrease information) is estimated for each route, and the tire heat state information is output to a terminal or a display unit. However, the tire heat state information may be output to an external device. An example of an external device is an automatic driving control device that controls automatic driving of a moving body. In addition, the technology disclosed herein is capable of estimating and outputting an optimal route and optimal conditions based on the tire heat state information for each estimated route. For example, the information processing device may control the determination of a route for the moving body to travel based on the tire heat state information for each estimated route, and then control the output of information to output information indicating the determined route to an external device or to display the information on a display unit such as the display unit 33, 53, etc.

[0117] For example, the above-mentioned control unit 504 may be configured to include a functional unit that functions as an output unit. The moving object 2 may be provided with a moving object control unit (not shown) that controls the moving object to automatically travel along a specified route. The control unit 504 may be configured to include a derivation unit that derives control information indicating that control regarding the traveling of the moving object is to be performed based on tire heat state information estimated from multiple specified parameter information, and a control information output unit that outputs the control information derived by the derivation unit to the moving object control unit.

[0118] In addition, in estimating at least one of the optimal route and the optimal conditions, the derivation unit may treat the specified multiple pieces of parameter information as a parameter information set, and derive control information based on multiple pieces of tire heat state information estimated by each of multiple different parameter information sets in which different parameter values ​​are specified.

[0119] The above control information can be information indicating a route along which a moving object travels from a first point to a second point.

[0120] When the control information to be provided to the moving body 2 is provided from outside the moving body 2, the control information may be generated outside the moving body 2 and provided to an automatic driving control device that controls the autonomous driving of the moving body 2. When the control information is derived in the moving body 2, the control information may be generated in the automatic driving control device that controls the autonomous driving, and the automatic driving control unit may control the moving body to drive autonomously in accordance with the control information.

[0121] In this way, the moving body 2 can be automatically caused to travel along an optimal route and under optimal conditions that are derived in accordance with the heat generated in the tires.

[0122] (Other embodiments) The above-mentioned user terminal 3 and server 5 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.

[0123] 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.

[0124] 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.
