Description

[Technical Field]

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

[0002] Conventionally, tire-rim-core assemblies in which a core is assembled to a rim have been known. In tire-rim-core assemblies, if the tire is punctured or the like, the core supports the inner surface of the tire, enabling run-flat driving. Patent Documents 1 and 2 disclose tire-rim-core assemblies of this type. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-312606 [Patent Document 2] Japanese Patent Application Publication No. 7-149118 Summary of the Invention [Problem to be solved by the invention]

[0004] The core to be mounted on the rim is usually determined according to the tire dimensions, maximum load capacity, etc., and does not necessarily take into consideration the actual conditions of use of the tire.

[0005] An object of the present disclosure is to provide an information processing device and an information processing method that are capable of determining core installation conditions according to the actual usage conditions of a tire. [Means for solving the problem]

[0006] An information processing device according to a first aspect of the present disclosure includes a control unit that determines the number of cores to be installed corresponding to tires mounted on a vehicle based on vehicle information about the vehicle. This allows the setting conditions of the core to be determined according to the actual conditions of use of the tire.

[0007] In one embodiment of the present disclosure, the vehicle information includes at least information on wheel loads imposed on the tires. This makes it easier to more accurately grasp the actual usage conditions of the tire.

[0008] In one embodiment of the present disclosure, the control unit determines the number of cores to be installed based on the vehicle information as well as application information of the vehicle. This allows a core that is more suitable for the actual use conditions of the tire to be determined.

[0009] In one embodiment of the present disclosure, the use information includes weight information of an object to be loaded on the vehicle. This makes it easier to more accurately grasp the actual usage conditions of the tire.

[0010] In one embodiment of the present disclosure, the control unit determines the type of the core based on tire information of the tire. This allows the type of core to be determined according to each different tire.

[0011] In one embodiment of the present disclosure, when the control unit determines that the number of cores to be installed is plural, it determines, as a usable rim, a rim whose support surface for supporting the core is a circumferential surface. This allows vehicle users and the like to be informed of the rim configuration in which multiple cores can be installed.

[0012] An information processing method according to a second aspect of the present disclosure is an information processing method executed by an information processing device, which determines the number of cores to be installed corresponding to tires mounted on a vehicle based on vehicle information about the vehicle. This allows the setting conditions of the core to be determined according to the actual conditions of use of the tire. [Effects of the Invention]

[0013] According to the present disclosure, it is possible to provide an information processing device and an information processing method that are capable of determining core installation conditions according to the actual usage conditions of a tire. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present disclosure will be described.

[0016] (Outline of the embodiment) An overview of an example of a system 1 according to an embodiment of the present disclosure will be described with reference to Fig. 1. The system 1 includes a vehicle 10 and an information processing device 20. The vehicle 10 and the information processing device 20 are communicably connected to a network 30 including, for example, the Internet and a mobile communication network.

[0017] The vehicle 10 is, for example, an automobile, but is not limited to this and may be any vehicle. The automobile may be, for example, a gasoline-powered automobile, an electric vehicle (EV), a hybrid vehicle (HV), a plug-in hybrid vehicle (PHV), or a fuel cell vehicle (FCV), but is not limited to these. The number of vehicles 10 included in the system 1 may be determined arbitrarily.

[0018] Furthermore, the type of automobile serving as vehicle 10 is not particularly limited, and may be, for example, a passenger car, a freight vehicle such as a truck, or a special-purpose vehicle.

[0019] The information processing device 20 is, for example, a computer such as a server device, etc. The information processing device 20 is capable of communicating with the vehicle 10 via a network 30.

[0020] First, an overview of this embodiment will be described, and details will be provided later. A wheel 50 including a rim 51, a core 60, and a tire 70 are mounted on a vehicle 10. The core 60 is assembled onto a support surface 51a of the rim 51 of the wheel 50. The core 60 supports the inner circumferential surface 70a of the tire 70 when a puncture or other problem occurs in the tire 70, enabling run-flat driving. The information processing device 20 determines the number of cores 60 to be installed corresponding to the tire 70 mounted on the vehicle 10 based on vehicle information about the vehicle 10. Furthermore, the information processing device 20 may determine the type of core 60 based on tire information about the tire 70 mounted on the vehicle 10. The tire information includes, for example, information such as tire width, height, aspect ratio, rim diameter, and load index. The type of core 60 refers to the size, material, and shape of the core 60.

[0021] As described above, according to this embodiment, the installation conditions, such as the type and number of cores 60 to be mounted on the rim 51, are determined based on information such as tire information about the tire 70 and vehicle information about the vehicle 10. Therefore, the installation conditions of the cores 60 that correspond to the actual usage conditions of the tire 70 can be determined based on the vehicle information about the vehicle 10 on which the tire 70 is actually mounted. This makes it possible to prevent, for example, a core 60 with a strength corresponding to the maximum load capacity of the tire 70 from being mounted on a vehicle 10 that does not use the tire 70 at its maximum load capacity, or to prevent the number of cores 60 that correspond to the maximum load capacity of the tire 70 from being mounted. In other words, it is possible to prevent a decrease in fuel efficiency and an increase in costs due to an increase in weight that occurs when a core 60 with a high strength that does not match the actual usage conditions of the tire 70 is mounted on the rim 51.

[0022] The information processing device 20 may be used, for example, as a support device that suggests the type and number of cores 60 to be installed according to the usage conditions of the tire 70 to the user, owner, manager, etc. of the vehicle 10 (hereinafter referred to as "user, etc. of the vehicle 10").

[0023] Next, each component of the system 1 will be described in detail.

[0024] (Vehicle configuration) As shown in FIG. 2, the vehicle 10 includes a communication unit 11, a storage unit 12, and a control unit 13.

[0025] The communication unit 11 includes one or more communication interfaces connected to the network 30. The communication interfaces are compatible with mobile communication standards such as, but not limited to, 4G (4th Generation) or 5G (5th Generation). In this embodiment, the vehicle 10 may communicate with the information processing device 20 via the communication unit 11 and the network 30.

[0026] The storage unit 12 includes one or more memories. The memories may be, for example, semiconductor memories, magnetic memories, optical memories, or the like, but are not limited to these. Each memory included in the storage unit 12 may function, for example, as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 stores any information used in the operation of the vehicle 10. For example, the storage unit 12 may store system programs, application programs, embedded software, and the like. The information stored in the storage unit 12 may be updatable with information obtained from the network 30 via the communication unit 11, for example.

[0027] The control unit 13 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. The processor may be, for example, a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for a specific process, but is not limited to these. The programmable circuit may be, for example, but is not limited to, an FPGA (Field-Programmable Gate Array). The dedicated circuit may be, for example, but is not limited to, an ASIC (Application Specific Integrated Circuit). The control unit 13 controls the overall operation of the vehicle 10.

[0028] (Configuration of information processing device) As shown in FIG. 3, the information processing device 20 includes a communication unit 21, a storage unit 22, an input unit 23, an output unit 24, and a control unit 25.

[0029] The communication unit 21 includes one or more communication interfaces connected to the network 30. The communication interfaces correspond to, for example, a mobile communication standard, a wired LAN (Local Area Network) standard, or a wireless LAN standard, but are not limited to these and may correspond to any communication standard. In this embodiment, the information processing device 20 may communicate with the vehicle 10 via the communication unit 21 and the network 30.

[0030] The storage unit 22 includes one or more memories. Each memory included in the storage unit 22 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 22 stores any information used in the operation of the information processing device 20. For example, the storage unit 22 may store system programs, application programs, databases, map information, etc. The information stored in the storage unit 22 may be updatable with information obtained from the network 30 via the communication unit 21, for example.

[0031] The input unit 23 is one or more input interfaces. Examples of the input interface include physical keys, capacitance keys, a pointing device, a touch screen integrated with a display, and a microphone. The input unit 23 accepts operations such as a user inputting information used in the operation of the information processing device 20.

[0032] The output unit 24 is one or more output interfaces. For example, a display or a speaker can be used as the output interface. For example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display can be used as the display. The output unit 24 outputs information obtained by the operation of the information processing device 20 to the user.

[0033] The control unit 25 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. The control unit 25 controls the overall operation of the information processing device 20.

[0034] (Operation flow of information processing device) An example of an information processing method executed by the information processing device 20 according to this embodiment will be described with reference to FIG.

[0035] Step S100: The control unit 25 of the information processing device 20 acquires tire information of the tire 70 mounted on the vehicle 10.

[0036] Any method can be used to acquire the tire information of the tire 70. For example, the control unit 25 may acquire the tire information of the tire 70 from an external device other than the vehicle 10, such as an external terminal such as a tablet or smartphone, or an external server, via the communication unit 21 and the network 30. The tire information of the tire 70 may also be stored in the storage unit 12 of the vehicle 10. In such a case, the control unit 25 may acquire the tire information of the tire 70 from the vehicle 10, for example, via the communication unit 21 and the network 30. Furthermore, the control unit 25 may acquire the tire information of the tire 70 by, for example, an input operation from the input unit 23.

[0037] Furthermore, the information processing device 20 may be used under conditions where tire information of the tires 70 is specified in advance. For example, the control unit 25 may store the tire information of the tires 70 of the vehicle 10 in the storage unit 22 in advance. In such a case, the control unit 25 only needs to execute processing under conditions where the tire information of the tires 70 is taken into account in advance, and does not need to acquire the tire information. In other words, this step S100 may be omitted.

[0038] Step S101: The control unit 25 determines the type of core 60 corresponding to the tire information of the tire 70.

[0039] By having the control unit 25 determine the type of core 60 based on the tire information of the tire 70, the processing of the control unit 25 in step S103 described below can be limited to determining the number of cores 60 to be installed, thereby reducing the burden on the control unit 25.

[0040] Furthermore, as described above, the information processing device 20 may be used, for example, under conditions where the tire information of the tire 70 has been specified in advance. In such cases, step S101 may be omitted. However, by determining the type of core 60 based on the tire information of the tire 70, as in this example, it is possible to determine the type of core 60 corresponding to each of the different tires 70 having different tire information.

[0041] The type of core 60 may be determined by appropriately combining tire information about the tire 70. The control unit 25 may determine the type of core 60 according to, for example, the load index of the tire 70. Specifically, as shown in Figures 5B and 5C, the control unit 25 may determine only one type of core 60b that can achieve a strength corresponding to the maximum load capacity of the tire 70 by arranging multiple cores (for example, two cores) at different positions in the rim width direction on the support surface 51a of the rim 51.

[0042] The control unit 25 may also determine two types of cores 60. Specifically, as shown in FIG. 5A, the control unit 25 may determine, for example, one type of core 60a that can achieve the strength corresponding to the maximum load capacity of the tire 70 by arranging only one core 60a in the rim width direction on the support surface 51a of the rim 51. Furthermore, as shown in FIGS. 5B and 5C, in addition to the one type of core 60a, the control unit 25 may determine another type of core 60b that can achieve the strength corresponding to the maximum load capacity of the tire 70 by arranging multiple cores (e.g., two cores) in different positions in the rim width direction on the support surface 51a of the rim 51. In this way, the control unit 25 may determine that the types of cores 60 corresponding to the tire information include two types of cores, cores 60a (see FIG. 5A) and 60b (see FIGS. 5B and 5C).

[0043] Furthermore, the types of cores 60 determined by control unit 25 are not limited to the one or two types described above, but may be three or more types.

[0044] Here, an example has been given of determining the type of core 60 based on the load index among the tire information, but the type of core 60 may be determined based on the tire width, height, etc. in addition to the load index of the tire 70 described above.

[0045] Note that information regarding the combination of tire information and the type of core 60 corresponding to this tire information may be set in advance. That is, the control unit 25 may determine the type of core 60 from the acquired tire information based on the information regarding the preset combination. The information regarding the combination of tire information and the type of core 60 corresponding to this tire information may be stored in the storage unit 22, or may be acquired from an external device such as an external server.

[0046] For ease of explanation, the following describes an example in which the control unit 25 determines only one type of core 60b (see FIGS. 5B and 5C) that can achieve a strength corresponding to the maximum load capacity of the tire 70 by placing two of them at different positions in the rim width direction on the support surface 51a of the rim 51. Furthermore, when there is no need to particularly distinguish between the cores 60a and 60b, they will simply be referred to as "core 60."

[0047] Step S102: The control unit 25 acquires vehicle information of the vehicle 10.

[0048] Any method can be adopted to acquire the vehicle information of the vehicle 10. For example, the control unit 25 may acquire the vehicle information of the vehicle 10 from an external device other than the vehicle 10, such as an external terminal such as a tablet or a smartphone, or an external server, via the communication unit 21 and the network 30. The vehicle information of the vehicle 10 may also be stored in the storage unit 12 of the vehicle 10. In such a case, the control unit 25 may acquire the vehicle information from the vehicle 10, for example, via the communication unit 21 and the network 30. Furthermore, the control unit 25 may acquire the vehicle information of the vehicle 10, for example, by an input operation from the input unit 23.

[0049] The vehicle information of the vehicle 10 may include, for example, the weight of the vehicle 10 itself. However, it is preferable that the vehicle information of the vehicle 10 includes at least information about the wheel load of the vehicle 10, which is the load applied to the tires 70. For example, the wheel loads applied to the front and rear tires 70 differ between a front engine, front drive vehicle (FF vehicle) and a front engine, rear drive vehicle (FR vehicle). Therefore, it is preferable to acquire information about the wheel load of the vehicle 10, which is the load applied to each tire 70. This makes it easier to more accurately grasp the actual usage conditions of each tire 70. The wheel load information of the vehicle 10 may be, for example, the wheel load itself, which is the vertical load applied to each tire 70 mounted on the vehicle 10, or the axle weight of the vehicle 10. In other words, the wheel load information of the vehicle 10 is not particularly limited as long as it is information from which the wheel load of the vehicle 10 can be derived.

[0050] Also, step S102 may be performed before the above-described step S101 of determining the type of core 60.

[0051] Step S103: The control unit 25 determines the number of cores 60b of the type determined in step S101 to be installed based on the vehicle information of the vehicle 10 acquired in step S102.

[0052] For example, when the control unit 25 determines, based on the wheel load applied to each tire 70, that the tire 70 is exerting less than half of its maximum load capacity, the control unit 25 determines the number of cores 60b of the type determined in step S101 to be only one (see FIG. 5B). Furthermore, when the control unit 25 determines, based on the wheel load applied to each tire 70, that the tire 70 is exerting more than half of its maximum load capacity, the control unit 25 determines the number of cores 60b of the type determined in step S101 to be two (see FIG. 5C). The above determination by the control unit 25 may be made, for example, based on a predetermined threshold value set for the wheel load applied to each tire 70.

[0053] In this way, the control unit 25 determines the number of cores 60b to be installed based on the vehicle information of the vehicle 10, taking into consideration the actual usage conditions of the tire 70.

[0054] Step S104: The control unit 25 determines whether the number of installed cores 60b determined in step S103 is plural or not.

[0055] Step S105: If it is determined in step S104 that the number of installed cores 60b is one, the control unit 25 notifies the determined type and number of installed cores 60b.

[0056] Any method can be used to notify the type and number of cores 60b. For example, the control unit 25 may notify the type and number of cores 60b by displaying the type and number of cores 60b on a display serving as the output unit 24. The control unit 25 may also notify the type and number of cores 60b by audio notification from a speaker serving as the output unit 24. Furthermore, the control unit 25 may transmit information about the type and number of cores 60b to the vehicle 10, an external device such as an external terminal such as a smartphone, or an external server via the communication unit 21 and the network 30, and notify the user of the vehicle 10 through the external device. This allows the user of the vehicle 10 to consider the type and number of cores 60b to actually use in the vehicle 10, for example, based on the notification information.

[0057] Step S106: If it is determined in step S104 that a plurality of cores 60b are installed, the control unit 25 notifies information about available rims in addition to the type and number of installed cores 60b.

[0058] Specifically, when the control unit 25 determines in step S104 that the number of installed cores 60b is multiple, that is, when the control unit 25 determines in step S103 that the number of installed cores 60b is multiple, it determines the rim 51 whose support surface 51a supporting the cores 60b is a circumferential surface as a usable rim.

[0059] When multiple cores 60b are installed in the rim width direction, it is preferable that the support surface 51a of the rim 51 on which the cores 60b are supported be a circumferential surface that is flat in a rim width cross-sectional view (see FIGS. 5B and 5C). Therefore, when the control unit 25 determines that multiple cores 60b are to be installed in step S103, it determines the rim 51 whose support surface 51a is a circumferential surface as a usable rim. This makes it possible to inform the user of the vehicle 10 of the rim configuration that can accommodate multiple cores 60b. As shown in FIG. 5C, such a rim 51 may be realized, for example, by a split rim having an inside rim 52a and an outside rim 52b that can be split at the center in the rim width direction.

[0060] Control unit 25 notifies information about the determined usable rims, in addition to the type and number of cores 60b, using the method described above in relation to step S105. This allows the user of vehicle 10 to consider the type and number of cores 60b to be used in vehicle 10, as well as consider the rims to be used in vehicle 10, such as whether the rim currently being used is a usable rim.

[0061] In this example, for the sake of convenience, an example has been described in which the number of installed cores is determined and notified for only one type of core 60b (see Figures 5B and 5C) determined in step S101, but if there are two or more types of cores 60 determined in step S101, the number of installed cores for each type of core 60 may be determined and notified.

[0062] Next, another example of the information processing method executed by the information processing device 20 according to this embodiment will be described with reference to FIG.

[0063] Steps S200 to S202: These steps are the same as steps S100 to S102 in FIG. 4, and therefore their explanation will be omitted here.

[0064] Step S203: The control unit 25 acquires the use information of the vehicle 10.

[0065] The usage information of the vehicle 10 is information relating to the conditions under which the vehicle 10 is actually used. For example, various devices may be retrofitted to the vehicle 10. Furthermore, the equipment in the interior space of the vehicle 10 may also be changed by the user. Furthermore, if the vehicle 10 is a cargo vehicle such as a truck, the total weight of the cargo may vary depending on, for example, the type of cargo. In other words, the usage information of the vehicle 10 includes various weight information that cannot be obtained from the vehicle information of the vehicle 10 in the conditions under which the vehicle 10 is actually used. By considering the usage information of the vehicle 10 in addition to the vehicle information of the vehicle 10, it becomes easier to more accurately grasp the actual usage conditions of the tire 70.

[0066] Here, the use information of the vehicle 10 preferably includes weight information of the cargo loaded on the vehicle 10. For example, the weight information of the cargo may include, but is not limited to, weight information of the cargo when the vehicle 10 is a freight vehicle such as a truck. Furthermore, the use information of the vehicle 10 is not limited to weight information of the cargo loaded on the vehicle 10, and may include information such as the type of road surface on which the vehicle 10 mainly travels and the average travel speed.

[0067] Any method can be employed to acquire the usage information of the vehicle 10. For example, the control unit 25 may acquire the usage information of the vehicle 10 from an external device other than the vehicle 10, such as an external terminal such as a tablet or a smartphone, or an external server, via the communication unit 21 and the network 30. The usage information of the vehicle 10 may also be stored in the storage unit 12 of the vehicle 10. In such a case, the control unit 25 may acquire the usage information from the vehicle 10, for example, via the communication unit 21 and the network 30. Furthermore, the control unit 25 may acquire the usage information of the vehicle 10, for example, by an input operation from the input unit 23.

[0068] Step S204: The control unit 25 determines the number of cores 60b of the type determined in step S201 to be installed based on the vehicle information of the vehicle 10 acquired in step S202 and the usage information of the vehicle 10 acquired in step S203.

[0069] For example, the control unit 25 may change the number of cores 60b to be installed, which was determined based on the vehicle information of the vehicle 10, based on the purpose information of the vehicle 10. The process by which the control unit 25 determines the number of cores 60b to be installed based on the vehicle information of the vehicle 10, may be the same as, for example, step S103 shown in FIG. 4. For example, the control unit 25 may determine the number of cores 60b of the type determined in step S201 to be only one based on the vehicle information of the vehicle 10. In such a case, the control unit 25 may change the number of cores 60b of the type determined in step S201 to two based on the purpose information of the vehicle 10. For example, the control unit 25 may determine to increase the number of cores 60b to be installed when the weight of the cargo actually loaded on the vehicle 10 is equal to or greater than a predetermined threshold. Alternatively, the control unit 25 may determine to increase the number of cores 60b to be installed when the type of road surface on which the vehicle 10 mainly travels is a mountain road. In this way, the control unit 25 may determine whether or not to change the number of installed cores 60b based on a predetermined threshold value set for the weight of the load loaded on the vehicle 10, for example.

[0070] In this example, the control unit 25 determines to increase the number of installed cores 60b from one to two based on the use information of the vehicle 10, but the control unit 25 may also determine to reduce the number of installed cores 60b based on the use information of the vehicle 10. For example, the control unit 25 may determine to reduce the number of installed cores 60b when the type of road surface on which the vehicle 10 mainly travels is an asphalt-paved road.

[0071] In this example, after the control unit 25 determines the number of cores 60b to be installed based on the vehicle information of the vehicle 10, the control unit 25 uses the usage information of the vehicle 10 to determine whether to change the determined number of cores 60b to be installed, but this is not limited to this. After acquiring the vehicle information of the vehicle 10 and the usage information of the vehicle 10, the control unit 25 may determine the number of cores 60b to be installed based on the vehicle information of the vehicle 10 and the usage information of the vehicle 10.

[0072] In this way, the control unit 25 determines the number of cores 60b to be installed based on the vehicle information and application information of the vehicle 10, taking into account the actual usage conditions of the tire 70. In this way, the control unit 25 can determine cores 60 that are more suitable for the actual usage conditions of the tire 70, compared to when the cores 60 are determined based only on the vehicle information of the vehicle 10.

[0073] Steps S205 to S207: These steps are the same as steps S104 to S106 in FIG. 4, and therefore their explanation will be omitted here.

[0074] The information processing device and information processing method according to the present disclosure are not limited to the above-described embodiments. For example, two or more blocks in the block diagram may be integrated, or one block may be divided. Instead of executing two or more steps in the flowchart chronologically as described, they may be executed in parallel or in a different order depending on the processing capacity of the information processing device executing each step, or as needed. Therefore, although the control unit 25 in the above-described embodiment determines the type of cores 60b based on tire information about the tire 70 and then determines the number of cores 60b to be installed based on vehicle information and usage information about the vehicle 10, this order is not limited. For example, the control unit 25 may acquire all of the tire information about the tire 70, the vehicle information about the vehicle 10, and the usage information about the vehicle 10, and then determine the type and number of cores 60 to be installed based on this information.
