[0018] An information processing system S including an information processing device 10 according to an embodiment will be described with reference to the drawings.

[0019] 1, an information processing system S according to this embodiment includes an information processing device 10, a server 12, and a vehicle 11. The information processing device 10, the server 12, and the vehicle 11 are connected via a network N and are capable of communicating with each other.

[0020] The information processing device 10 is installed, for example, outside the vehicle 11, and is configured to receive instructions from the vehicle 11 and transmit requested information. The information processing device 10 is also configured to be able to acquire various information from a server 12 via a network N. The information processing device 10 may be connected to a plurality of vehicles 11 via the network N.

[0021] The vehicle 11 is equipped with an on-board device 28. In this embodiment, the on-board device 28 is, for example, an ECU (Electronic Control Unit) that performs various controls. The server 12 is installed outside the vehicle 11 and is configured to be able to receive data from the artificial satellite 13. For this reason, the server 12 stores satellite images taken by the artificial satellite. The server 12 also stores map information and the like, and transmits the required map information via the network N in response to a request from the on-board device 28 (vehicle 11).

[0022] The information processing system S of this embodiment is configured as described above, and the information processing device 10 acquires a driving route to a destination of the vehicle 11, acquires satellite images of locations corresponding to the driving route taken by an artificial satellite 13, and estimates the amount of solar radiation along the driving route based on the satellite images. The information processing device 10 is then configured to notify the user if the amount of solar radiation is equal to or greater than a threshold.

[0023] (Hardware configuration of information processing device 10) 2, the information processing device 10 includes a CPU (Central Processing Unit: processor) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, and a communication interface (communication I / F) 38. Each component is connected to each other via an internal bus 39 so as to be able to communicate with each other.

[0024] The CPU 30 is a central processing unit that executes various programs and controls each part. That is, the CPU 30 reads programs from the ROM 32 or storage 36 and executes the programs using the RAM 34 as a work area. The CPU 30 also controls the above-mentioned components and performs various arithmetic processing in accordance with the programs recorded in the ROM 32 or storage 36.

[0025] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores programs or data as a working area. The storage 36 is configured by an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 32 or the storage 36 stores programs for performing various processes.

[0026] The communication I / F 38 is an interface through which the information processing device 10 communicates with the server 12, the vehicle-mounted device 28, and other devices, and uses standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0027] (Hardware configuration of on-board unit 28) 3, the vehicle-mounted device 28 includes a CPU 40, a ROM 42, a RAM 44, a storage 46, a communication interface (communication I / F) 48, and an input / output interface (input / output I / F) 50. Each component is connected to each other via an internal bus 52 so as to be able to communicate with each other.

[0028] The CPU 40 is a central processing unit that executes various programs and controls each component. That is, the CPU 40 reads programs from the ROM 42 or storage 46 and executes the programs using the RAM 44 as a work area. The CPU 40 also controls the above-mentioned components and performs various arithmetic processing in accordance with the programs recorded in the ROM 42 or storage 46.

[0029] The ROM 42 stores various programs and various data. The RAM 44 temporarily stores programs or data as a working area. The storage 46 is composed of an HDD or SSD and is a non-transitory recording medium that stores various programs including the operating system and various data.

[0030] The communication I / F 48 is an interface through which the vehicle-mounted device 28 communicates with a server and other devices, and uses standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0031] A navigation system 54, a GPS (Global Positioning System) device 56, a display device 58, and a speaker 60 are connected to the input / output I / F 50. The navigation system 54 sets a driving route from the current location of the vehicle 11 to the destination, and provides various guidance so that the vehicle 11 can travel along the driving route. At this time, the navigation system 54 appropriately acquires map information from the server 12. Furthermore, if some or all of the map information is stored in the storage 46, the driving route may be set without acquiring map information from the server 12.

[0032] The GPS device 56 is a device that receives GPS signals from GPS satellites to determine the current position of the vehicle 11. The display device 58 displays various information on a display unit (not shown) provided inside the vehicle cabin. For example, the display device 58 displays information on the driving route set by the navigation system 54, information on the amount of solar radiation, etc.

[0033] The speaker 60 is provided in the vehicle interior and is configured to be able to output sound to the occupants.

[0034] (Functional configuration of information processing device 10) The information processing device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the information processing device 10 will be described with reference to FIG.

[0035] 4, the information processing device 10 includes, as functional components, a driving route acquisition unit 62, a satellite image acquisition unit 64, a solar radiation amount estimation unit 66, a driving route reconstruction unit 68, a tire deterioration degree calculation unit 70, and a notification unit 72. Each functional component is realized by the CPU 30 reading and executing a program stored in the ROM 32 or the storage 36.

[0036] The travel route acquisition unit 62 acquires a travel route from the current location of the vehicle 11 to the destination. Specifically, the current location of the vehicle 11 is set based on information from the GPS device 56, and a travel route from the current location of the vehicle 11 to the destination is calculated. The destination may be input to the information processing device 10 by an operation by the occupant, for example.

[0037] The travel route may be calculated by the in-vehicle device 28 or by an external server 12. For example, the current position information of the vehicle 11 and information on the destination may be transmitted to the server 12, and the server 12 may calculate the travel route by referring to map information. The travel route acquisition unit 62 acquires information related to the travel route calculated by the in-vehicle device 28 or the server 12.

[0038] The satellite image acquisition unit 64 acquires satellite images taken by the artificial satellite 13. Specifically, the satellite image acquisition unit 64 accesses the server 12 and acquires satellite images corresponding to the driving route from among the satellite images stored in the server 12. The satellite images acquired by the satellite image acquisition unit 64 are satellite images in which areas illuminated by sunlight and areas in shadow can be distinguished.

[0039] The solar radiation estimation unit 66 estimates the amount of solar radiation along the driving route based on the satellite images acquired by the satellite image acquisition unit 64. In this embodiment, as an example, the amount of solar radiation is estimated using a trained model. Specifically, information about the driving route and satellite images is input to the trained model, and an estimated value of the amount of solar radiation along the driving route is output. The input satellite image information may be satellite images taken at the same location at a predetermined interval. Weather information may also be input in addition to the information about the driving route and satellite images. The trained model may be trained using multiple training datasets, each consisting of a set of data including the driving route and satellite images corresponding to the driving route, and data about solar radiation, as training data. For example, a solar radiation sensor mounted on the vehicle may be used as the solar radiation data. As an example, the trained model is machine-learned using a known technique such as deep learning.

[0040] When the amount of solar radiation on the driving route is equal to or greater than a threshold, the driving route reconstructing unit 68 reconstructs the driving route so that the amount of solar radiation is less than the threshold. Specifically, when the amount of solar radiation on the driving route estimated by the solar radiation estimating unit 66 is equal to or greater than a preset threshold, the driving route reconstructing unit 68 identifies a driving route in which the amount of solar radiation is less than the threshold from among candidate driving routes other than the driving route acquired by the driving route acquiring unit 62. As another method, a driving route that allows driving in the shade may be identified by changing part of the driving route acquired by the driving route acquiring unit 62. Note that the amount of solar radiation used to determine whether the amount of solar radiation on the driving route is equal to or greater than a threshold may be the amount of solar radiation on the entire driving route or the amount of solar radiation at each predetermined distance on the driving route.

[0041] In addition, as an example in this embodiment, the driving route reconstructing unit 68 reconstructs the driving route by adding information about the direction of sunlight when the vehicle 11 is traveling. Specifically, from among the candidate driving routes, driving routes in which the sun is located in the direction of travel of the vehicle 11 are excluded. In other words, the driving route is reconstructed so as to minimize the state in which light shines directly in front of the occupants when the vehicle 11 is traveling.

[0042] The tire deterioration degree calculation unit 70 calculates the degree of deterioration of the tires of the vehicle 11 based on the estimated amount of solar radiation. Specifically, the tire deterioration degree calculation unit 70 acquires information about the tires of the vehicle 11 that has been stored in advance in the storage 36 or an external server, and estimates the current degree of deterioration of the tires. The degree of deterioration of the tires is estimated based on the mileage of the vehicle 11, the amount of use, the time elapsed since tire replacement, the amount of solar radiation, etc.

[0043] The tire deterioration degree calculation unit 70 calculates the degree of tire deterioration when the vehicle travels along the travel route, taking into account the amount of solar radiation estimated by the solar radiation estimation unit 66 for the estimated current degree of tire deterioration. At this time, the degree of tire deterioration may be estimated using a trained model. Specifically, by inputting information on the current degree of tire deterioration, the travel route, and the amount of solar radiation into the trained model, an estimated value of the degree of tire deterioration when the vehicle travels along the travel route is output. Note that the degree of tire deterioration may also be estimated by inputting information such as the road surface condition along the travel route.

[0044] The notification unit 72 issues a notification when the amount of solar radiation estimated by the solar radiation estimation unit 66 is equal to or greater than a threshold. The notification by the notification unit 72 is issued by displaying on the display device 58 and outputting sound from the speaker 60, etc.

[0045] Furthermore, when the driving route is reconstructed by the driving route reconstruction unit 68, the notification unit 72 causes the display device 58 to display the original driving route and the reconstructed driving route in the display area. At this time, the notification unit 72 may also display estimated values of the amount of solar radiation when traveling along each of the driving routes.

[0046] Furthermore, the notification unit 72 notifies the user of the degree of tire deterioration calculated by the tire deterioration degree calculation unit 70. If the degree of tire deterioration has reached a level that indicates a tire replacement, the notification unit 72 may issue a notification urging the user to replace the tire.

[0047] (action) Next, the operation of this embodiment will be described.

[0048] An example of information processing for notifying the occupant of information will be described with reference to the flowchart shown in Fig. 5. This display processing is executed by the CPU 30 reading a display program from the ROM 32 or storage 36, and expanding and executing the program in the RAM 34. Note that in this embodiment, as an example, the information processing is executed when a driving route is displayed after a destination is set by the user.

[0049] In step S102, the CPU 30 acquires a travel route. Specifically, the CPU 30 acquires a travel route from the current position of the vehicle 11 to the destination using the function of the travel route acquisition unit 62.

[0050] In step S104, the CPU 30 acquires satellite images. Specifically, the CPU 30 uses the function of the satellite image acquisition unit 64 to acquire, from among the satellite images stored in the server 12, a satellite image that corresponds to the travel route.

[0051] The CPU 30 estimates the amount of solar radiation in step S106. Specifically, the CPU 30 uses the function of the solar radiation estimation unit 66 to estimate the amount of solar radiation on the travel route based on the satellite image acquired by the satellite image acquisition unit 64.

[0052] In step S108, CPU 30 determines whether the amount of solar radiation is equal to or greater than a threshold. Specifically, CPU 30 compares the amount of solar radiation estimated in step S106 with a predetermined threshold, and if the amount of solar radiation is equal to or greater than the threshold, proceeds to processing in step S110. On the other hand, if the amount of solar radiation estimated in step S106 is less than the threshold, CPU 30 ends this processing.

[0053] The CPU 30 reconstructs the driving route in step S110. Specifically, the CPU 30 causes the driving route reconstruction unit 68 to reconstruct the driving route so that the amount of solar radiation is less than a threshold value. For example, the driving route reconstruction unit 68 identifies a driving route in which the amount of solar radiation is less than a threshold value from among candidate driving routes other than the driving route acquired by the driving route acquisition unit 62. At this time, the CPU 30 may reconstruct the driving route by adding information about the direction of solar radiation when the vehicle 11 is traveling.

[0054] In step S112, the CPU 30 notifies the occupant. Specifically, the CPU 30 notifies the occupant that the amount of solar radiation estimated by the solar radiation amount estimation unit 66 is equal to or greater than a threshold value using the function of the notification unit 72. The notification by the notification unit 72 is performed by displaying on the display device 58 and outputting sound from the speaker 60, etc.

[0055] In step S112, CPU 30 causes display device 58 to display the original driving route and the reconstructed driving route in the display area. At this time, estimated values of the amount of solar radiation when traveling along each driving route may also be displayed. Furthermore, notification unit 72 may notify the degree of tire deterioration calculated by tire deterioration degree calculation unit 70. Then, CPU 30 ends this process.

[0056] As described above, according to the information processing system S and the information processing device 10 of this embodiment, satellite images of locations corresponding to the driving route to the destination are acquired, and the amount of solar radiation on the driving route is estimated based on these satellite images, thereby making it possible to estimate the amount of solar radiation in real time taking into account the weather, etc.

[0057] Furthermore, if the amount of solar radiation is equal to or greater than a threshold, the notification unit 72 issues a notification, allowing the user to understand the deterioration of the vehicle 11 due to the amount of solar radiation.

[0058] Furthermore, in this embodiment, the driving route reconstructing unit 68 reconstructs the driving route so that the amount of solar radiation is less than a threshold value. This makes it possible to suppress deterioration of the vehicle 11. In particular, in this embodiment, the driving route is reconstructed by adding information about the direction of solar radiation, so that, for example, by excluding driving routes in which the traveling direction of the vehicle 11 and the direction of the sun coincide, it is possible to set a driving route that does not dazzle the driver.

[0059] Furthermore, in this embodiment, the degree of tire deterioration is notified by the notification unit 72, so that the user can directly grasp the degree of tire deterioration.

[0060] The information processing system S and the information processing device 10 according to the embodiment have been described above. However, it goes without saying that the present invention can be embodied in various forms without departing from the spirit and scope of the present invention. For example, in the above embodiment, the driving route reconstruction unit 68 is configured to reconstruct the driving route when the amount of solar radiation on the driving route is equal to or greater than a threshold value. However, the present invention is not limited to this. That is, when the amount of solar radiation on the driving route is equal to or greater than a threshold value, the user may be notified and asked whether or not to reconstruct the driving route. In this case, if the user does not want to reconstruct the driving route, unnecessary processing may not be performed.

[0061] Furthermore, the processing performed by the CPU 30 after reading the program in the above embodiment may be performed by various processors other than the CPU 30. Examples of such processors include dedicated electrical circuits, such as programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)) whose circuit configuration can be changed after fabrication, and application-specific integrated circuits (ASICs) that are processors with circuit configurations specifically designed to perform specific processing. The processing may be performed by one of these various processors, or by a combination of two or more processors of the same or different types, such as multiple FPGAs or a combination of a CPU and an FPGA. The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0062] Furthermore, in the above embodiment, various data is stored in the storage 36, but this is not limiting. For example, a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs, data, etc. are stored in these recording media.

[0063] Furthermore, the processing flow described in the above embodiment is an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed within the scope of the main idea. [Explanation of symbols]
