DETAILED DESCRIPTION OF THE INVENTION

[0009] An information processing device according to one aspect of the present disclosure includes a control unit that outputs a notification that the vehicle needs to be refueled based on information relating to a range that the vehicle can travel and information relating to a distance from the vehicle to a refueling station.

[0010] A vehicle is a vehicle that can run using fuel or electricity. The drivable range of a vehicle is the distance the vehicle can run without refueling or charging. A fueling station is a location where fuel or electricity can be refueled, such as a gas station or a charging station. In the case of a vehicle equipped with an engine, there is a correlation between the amount of fuel stored in the vehicle and the drivable range, and in the case of an electric vehicle, there is a correlation between the remaining charge in the battery and the drivable range. Therefore, for example, the drivable range of a vehicle can be calculated based on the remaining amount of fuel or the remaining charge in the battery.

[0011] If the vehicle user does not understand the relationship between the driving distance and the distance to the refueling station, there is a risk that the remaining fuel or charge will run out before the vehicle reaches the refueling station, rendering the vehicle unable to drive. Electric vehicles are particularly susceptible to becoming unable to drive because there are still few charging stations. Furthermore, when using a car share or rental car service, the user may overlook the remaining fuel or charge because the vehicle is unfamiliar. Furthermore, in unfamiliar areas, the user may not know where the refueling station is located. Therefore, the control unit outputs a notification when there is a possibility that the vehicle will become unable to drive. In other words, by notifying the user that refueling is necessary, the vehicle can arrive at the refueling station. The notification may be output to the user's terminal or to the vehicle.

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The configurations of the following embodiments are examples, and the present disclosure is not limited to the configurations of the embodiments. Furthermore, the following embodiments can be combined as much as possible.

[0013] First Embodiment 1 is a diagram showing a schematic configuration of a system 1 according to a first embodiment. The system 1 includes a vehicle 10, a user terminal 20, a server 30, and a charging station 40. The system 1 is a system in which the server 30 notifies the user before a charging station 40 disappears from a driving range of the vehicle 10.

[0014] The vehicle 10 is a battery electric vehicle (BEV). The vehicle 10 may be a vehicle owned by a user, a vehicle used for car sharing, or a rental car. The user is the driver of the vehicle 10 and possesses a user terminal 20. The charging station 40 is a device that can charge the battery 16 of the vehicle 10 by supplying power to the vehicle 10. There are multiple charging stations 40.

[0015] The server 30 notifies the user when the distance obtained by subtracting a predetermined distance from the vehicle's drivable distance based on the location of the vehicle 10, the remaining charge of the battery 16 of the vehicle 10, and the locations of each charging station 40 becomes equal to or less than the distance to the most recent charging station 40. In other words, the server 30 notifies the user when the following condition is met: "Drivable distance - predetermined distance ≦ distance to the most recent charging station." This prevents the vehicle 10 from being unable to travel to a charging station 40. The predetermined distance is a distance equivalent to the margin of error required for the vehicle 10 to travel to the most recent charging station 40. Here, the drivable distance is estimated based on the remaining charge of the battery 16. However, the actual distance that the vehicle 10 can travel may vary depending on, for example, the usage status of the air conditioner or the like or road conditions (e.g., the gradient of a slope), so the server 30 notifies the user with a certain margin of error. The predetermined distance may be determined by the user. In this case, the user may input the predetermined distance to the input / output unit 24 of the user terminal 20 or the input / output unit 14 of the vehicle 10, and this information may be transmitted to the server 30. The predetermined distance may also be set to 0. Note that the method for calculating the remaining driving distance may be any known method.

[0016] In this embodiment, an example will be described in which the vehicle 10 is a BEV and is charged at a charging station 40, but the present invention is not limited to this and can be similarly applied to cases in which fuel such as gasoline is filled up at a gas station.

[0017] FIG. 2 is a diagram showing the relationship between the vehicle 10 and the charging station 40. The dashed-dotted circle centered on the vehicle 10 indicates the distance from the vehicle 10, which is the distance obtained by subtracting a predetermined distance from the travelable distance. In the following, the distance obtained by subtracting the predetermined distance from the travelable distance will also be referred to as the notified distance. In FIG. 2, reference numeral 51 indicates a case where two charging stations (a first charging station 40A and a second charging station 40B) are present within the notified distance from the vehicle 10. When the vehicle 10 moves to the right in FIG. 2 , the second charging station 40B first moves out of the notification distance. Next, reference numeral 52 indicates a case where the first charging station 40A is the only charging station 40 within the notification distance from the vehicle 10, and the distance from the vehicle 10 to the first charging station 40A is equal to the notification distance. This state triggers a charge notification to be sent to the vehicle 10 or the user terminal 20. That is, the charge notification is sent when the condition "notification distance≦distance to the most recent charging station" is met. The charge notification is a notification to encourage the user to charge. The charge notification may include a notification to inform the user that there is no longer a charging station 40 within the driving distance of the vehicle 10. The charge notification may be sent to the user terminal 20 or the vehicle 10. Upon receiving the charge notification, the vehicle 10 or the user terminal 20 may, for example, display on a screen or provide audio guidance indicating that charging is required. This allows the user to recognize that charging is required.

[0018] The vehicle 10, the user terminal 20, the server 30, and the charging station 40 are interconnected via a network N1. The network N1 may be a global public communication network such as the Internet, and may be a wide area network (WAN) or other communication network. The network N1 may also include a telephone communication network such as a mobile phone network, or a wireless communication network such as Wi-Fi (registered trademark).

[0019] The server 30 has the configuration of a computer. The server 30 includes a processor 31, a main memory unit 32, an auxiliary memory unit 33, and a communication unit 34. These are connected to each other via a bus. The processor 31 is an example of a control unit.

This allows the server 30 to realize functions that meet a predetermined purpose. The main storage unit 32 and the auxiliary storage unit 33 are computer-readable recording media.

[0021] The communication unit 34 is a means for communicating with the vehicle 10, the user terminal 20, and the charging stand 40 via the network N1. The communication unit 34 is, for example, a LAN (Local Area Network) interface board or a wireless communication circuit for wireless communication. The LAN interface board and the wireless communication circuit are connected to the network N1.

[0022] The vehicle 10 includes a processor 11, a main memory 12, an auxiliary memory 13, an input / output unit 14, a communication unit 15, a battery 16, and a location information sensor 17. These components are interconnected by a CAN bus, which is an in-vehicle network bus. The processor 11, the main memory 12, and the auxiliary memory 13 are similar to the processor 31, the main memory 32, and the auxiliary memory 33 of the server 30, and therefore a description thereof will be omitted.

[0023] The input / output unit 14 is a unit that receives input operations performed by the user and presents information to the user. In this embodiment, it is composed of a single touch panel display. The input / output unit 14 may include input devices such as a mouse, a keyboard, push buttons, and a microphone. The input / output unit 14 may also include output devices such as an LCD (Liquid Crystal Display), an EL (Electroluminescence) panel, and a speaker. .

[0024] The communication unit 15 is a communication means for connecting the vehicle 10 to the network N1. The communication unit 15 may be, for example, a mobile communication service (for example, a telephone communication network such as 6G (6th Generation), 5G (5th Generation), 4G (4th Generation), 3G (3rd Generation), or LTE (Long Term Evolution)), Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like. ), NFC (Near Field Communication), UWB (Ultra Wideband), or other wireless communication network, and is a circuit for communicating with other devices (such as the server 30) via the network N1.

[0025] The battery 16 is a secondary battery that can be repeatedly charged and discharged, and can supply power to an electric motor that drives the vehicle 10. The position information sensor 17 acquires position information (e.g., latitude and longitude) of the vehicle 10 at predetermined intervals. The position information sensor 17 is, for example, a GPS (Global Positioning System) receiving unit, a wireless communication unit, etc.

[0026] The user terminal 20 is a small computer such as a smartphone, a mobile phone, a tablet terminal, a personal information terminal, a wearable computer (such as a smart watch), or a personal computer (PC). The user terminal 20 includes a processor 21, a main memory unit 22, an auxiliary memory unit 23, an input / output unit 24, and a communication unit 25. The processor 21, the main memory unit 22, and the auxiliary memory unit 23 are similar to the processor 31, the main memory unit 32, and the auxiliary memory unit 33 of the server 30, and therefore their description will be omitted. The input / output unit 24 and the communication unit 25 are similar to the input / output unit 14 and the communication unit 15 of the vehicle 10, and therefore their description will be omitted.

[0027] The charging stand 40 includes a processor 41, a main memory unit 42, an auxiliary memory unit 43, an input / output unit 44, and a communication unit 45. The processor 41, the main memory unit 42, and the auxiliary memory unit 43 are similar to the processor 31, the main memory unit 32, and the auxiliary memory unit 33 of the server 30, and therefore their description will be omitted. The input / output unit 44 and the communication unit 45 are similar to the input / output unit 14 and the communication unit 15 of the vehicle 10, and therefore their description will be omitted.

[0028] Next, the functions of the server 30 will be described. Fig. 3 is a diagram illustrating an example of the functional configuration of the server 30. The server 30 includes, as functional components, a control unit 301, a vehicle information DB 311, a station information DB 312, and a map information DB 313. The processor 31 of the server 30 executes the processing of the control unit 301 using a computer program on the main memory unit 32. The vehicle information DB 311, the station information DB 312, and the map information DB 313 are, for example, relational databases, and are constructed by a database management system (DBMS) program executed by the processor 31 managing data stored in the auxiliary memory unit 33.

[0029] The control unit 301 communicates with the vehicle 10, collects information about the vehicle 10 (hereinafter also referred to as vehicle information), and stores it in the vehicle information DB 311. The vehicle information includes information about the remaining charge (hereinafter also referred to as SOC) of the battery, and location information. The location information is information about the current location of the vehicle 10 detected by the location information sensor 17 of the vehicle 10. The SOC information is information about the remaining charge of the battery 16 detected in the vehicle 10. The location information and the SOC information are transmitted from the vehicle 10 to the server 30 at predetermined time intervals.

[0030] The control unit 301 also communicates with the vehicle 10 or the user terminal 20, collects information about search conditions for the charging stations 40, and stores the information in the vehicle information DB 311. The information about the search conditions may be included in the vehicle information. This information is information about the conditions of the charging stations 40 to be searched for when searching for charging stations 40 that are compatible with the charging station 40. Some charging stations 40 are compatible with rapid charging, and using this rapid charging can shorten the charging time. Therefore, it is conceivable that the user wishes to use only charging stations 40 that are compatible with rapid charging. In such a case, only charging stations 40 that are compatible with rapid charging will be included in the search.

[0031] Furthermore, if a charging station 40 is in use by another user, a waiting time may occur. For this reason, it is conceivable that a user wishes to use only vacant charging stations 40. In such cases, only vacant charging stations 40 are included in the search targets. Furthermore, there are charging stations 40 that can be used free of charge and those that can be used for a fee. It is also conceivable that a user wishes to use only charging stations 40 that can be used free of charge. In such cases, only charging stations 40 that can be used free of charge are included in the search targets.

[0032] Furthermore, even among available charging stations 40, there may be charging stations 40 located in a direction other than the vehicle's direction of travel. For example, if the most recent charging station 40 is located in the opposite direction from the vehicle's direction of travel, the user will have to go back the way they came. Therefore, the user may wish to use only charging stations 40 located in the vehicle's direction of travel. In such cases, only charging stations 40 located in the vehicle's direction of travel are included in the search. Furthermore, it is possible that the voltage of a charging station 40 is not compatible with the vehicle 10. Therefore, only charging stations 40 that can charge the vehicle 10 at a voltage compatible with the vehicle 10 are included in the search.

[0033] As described above, the information about the search target includes information about the user's requests, such as whether to limit the search to charging stations 40 that allow quick charging, whether to limit the search to charging stations 40 that are not in use, whether to limit the search to charging stations 40 that are available free of charge, or whether to limit the search to charging stations 40 that are located in the direction of travel of the vehicle 10, and information about standards or specifications, such as limiting the search to charging stations 40 whose voltage is compatible with the vehicle 10. The information about the search target is generated based on, for example, what the user inputs to the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20, and is transmitted to the server 30.

[0034] The vehicle information DB 311 stores information about the location, SOC, and search target for each vehicle 10.

[0035] The station information DB 312 also stores information (hereinafter also referred to as charging station information) corresponding to each charging station 40, such as the location, usage status, reservation status, whether or not quick charging is supported, whether or not free charging is available, and voltage. The location information of each charging station 40 is information about the location where each charging station 40 is installed, and is registered, for example, by the administrator of the charging station 40. The usage status information is information that enables determination of whether or not the charging station 40 is currently being used, and is transmitted from the charging station 40 to the server 30 at predetermined intervals. The reservation status information is information about the time for which the charging station 40 is reserved. A reservation for a charging station 40 can be made, for example, from the vehicle 10 or the user terminal 20. The reservation is accepted by the control unit 301, and the station information DB 312 is updated. Whether or not quick charging is supported and whether or not free charging is available is registered, for example, in the server 30 by the administrator of the charging station 40. The voltage information is information about the voltage corresponding to the charging time, and is registered, for example, in the server 30 by the administrator of the charging station 40.

[0036] The map information DB 313 stores, as map information, for example, link data relating to roads (links). The data stored in the database includes route data, node data relating to node points, intersection data relating to each intersection, search data for searching for routes, and search data for searching for points.

[0037] The control unit 301 also calculates the remaining driving distance based on the SOC of the vehicle 10. Because the remaining driving distance is correlated with the SOC, for example, a calculation formula or map for calculating the remaining driving distance from the SOC is stored in the auxiliary storage unit 33. The control unit 301 then calculates the notification distance by subtracting a predetermined distance from the remaining driving distance. Information regarding the predetermined distance may be transmitted from the vehicle 10 or the user terminal 20, or may be input by an administrator of the server 30. The control unit 301 searches for the charging station 40 closest to the vehicle 10. This most recent charging station 40 is the charging station closest to the vehicle 10 among the charging stations that match the search criteria. The control unit 301 then transmits a charging notification to the vehicle 10 or the user terminal 20 when the distance from the vehicle 10 to the most recent charging station 40 is equal to or greater than the notification distance.

[0038] Fig. 4 is a flowchart of the processing in the server 30 according to the first embodiment. The processing shown in Fig. 4 is executed at predetermined time intervals by the server 30 for each vehicle 10. Note that the following description will be given assuming that the vehicle information DB 311 and the station information DB 312 store necessary information.

[0039] In step S101, the control unit 301 acquires vehicle information. Since the vehicle information is stored in the vehicle information DB 311, the control unit 301 acquires the latest vehicle information corresponding to the vehicle 10 from the vehicle information DB 311. In step S102, the control unit 301 calculates the remaining driving distance of the vehicle 10. The control unit 301 calculates the remaining driving distance by substituting the SOC included in the vehicle information into a calculation formula stored in the auxiliary storage unit 33.

[0040] In step S103, the control unit 301 identifies the most recent charging station 40. Based on the vehicle information and the charging station information, the control unit 301 identifies the charging station 40 that is closest to the vehicle 10 among the charging stations 40 that match the search targets. For example, if a charging station 40 is in use by another user but allows the user to wait, the charging station 40 is included in the search target. On the other hand, if a charging station 40 is in use by another user and is fully booked, the charging station 40 cannot be used even if the user waits, and therefore is excluded from the search target.

[0041] Then, in step S104, the control unit 301 determines whether the distance obtained by subtracting a predetermined distance from the available driving distance calculated in step S102 is equal to or less than the distance to the charging station 40 identified in step S103. That is, the control unit 301 determines whether the distance to the most recent charging station 40 is equal to or greater than the notified distance. The predetermined distance is stored in the auxiliary storage unit 33. If the determination in step S104 is affirmative, the control unit 301 reserves the charging station 40 in step S105. If the vehicle 10 is not charged at the identified charging station 40, there is a risk that the vehicle 10 will become unable to drive. Therefore, the user is likely to head to the charging station 40. Therefore, the control unit 301 reserves the charging station 40. That is, the control unit 301 updates information related to the reservation status in the station information DB 312. Note that this reservation is not essential. Therefore, the processing of step S105 can be omitted. On the other hand, if the determination in step S104 is negative, the present routine is terminated.

[0042] In step S106, the control unit 301 transmits a charging notification to the vehicle 10 or the user terminal 20. This charging notification may include a command to cause the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20 to output a message indicating that the battery will run out of power if charging is not performed and the location of the most recent charging station 40. This command may be displayed on a screen on the display. The command may be a command to output a message from the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20 indicating that the charging station 40 has been reserved, or a command to play a voice from a speaker. The command may also include a command to output a message indicating that the charging station 40 has been reserved, to the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20. The command may also include a command to display a route to the charging station 40, to the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20.

[0043] As described above, according to this embodiment, a charging notification is sent to the vehicle 10 at the time when no charging station 40 exists within the notification distance, so that the user can be made aware of the need for charging.

[0044] Second Embodiment In the first embodiment, a charging notification is sent based on the distance to the most recent charging station 40, but in the second embodiment, a charging notification is sent when the number of charging stations 40 within the notification distance falls below a predetermined number. In this case, since it is not known which charging station 40 the user is heading for, the user may be asked which charging station 40 the user is heading for, and the charging station 40 may be reserved based on the user's response.

[0045] Fig. 5 is a flowchart of the processing in the server 30 according to the second embodiment. The processing shown in Fig. 5 is executed at predetermined time intervals by the server 30 for each vehicle 10. Note that steps in which the same processing as in the routine shown in Fig. 4 is executed are denoted by the same reference numerals, and explanations thereof will be omitted.

[0046] In the flowchart shown in Fig. 5, once the processing of step S102 is completed, the process proceeds to step S201. In step S201, the control unit 301 identifies a predetermined number of charging stations 40 in ascending order of distance from the vehicle 10. Based on the vehicle information and the charging station information, the control unit 301 identifies the charging stations 40 that match the search target in descending order of distance from the vehicle 10. The predetermined number may be specified by the user using the user terminal 20 or the vehicle 10, or may be specified by an administrator of the server 30, for example.

[0047] In step S202, the control unit 301 determines whether the distance obtained by subtracting a predetermined distance from the travelable distance calculated in step S102 is equal to or less than the distance to the farthest charging station 40 among the charging stations 40 identified in step S201. In other words, the control unit 301 determines whether the distance to the farthest charging station 40 is equal to or greater than the notified distance. If the determination in step S202 is affirmative, the process proceeds to step S203, and if the determination is negative, the routine is terminated.

[0048] In step S203, the control unit 301 transmits a charging notification to the vehicle 10 or the user terminal 20. This notification may include a command to output to the input / output unit 14 of the vehicle 10 or the input / output unit 24 of the user terminal 20 that the battery will run out of power if charging is not performed and the location of a movable charging station 40. The notification may also include an inquiry as to whether or not to reserve the charging station 40. For example, the charging stations 40 identified in step S201 may be displayed on the screen of the input / output unit 14 of the vehicle 10, and the charging station 40 tapped by the user may be acquired to thereby acquire the charging station 40 to be reserved. When the charging station 40 to be reserved is acquired in the vehicle 10, information about the charging station 40 to be reserved is transmitted from the vehicle 10 to the server 30. The user may also select the charging station 40 to be reserved by voice.

[0049] In step S204, the control unit 301 determines whether or not reservation information has been received from the vehicle 10 or the user terminal 20. The reservation information is information relating to the charging station 40 to be reserved, and is information transmitted from the vehicle 10 or the user terminal 20. If the result of step S204 is YES, If this determination is affirmative, the process proceeds to step S205, where the control unit 301 reserves the charging station 40 designated by the user. On the other hand, if the determination is negative in step S204, the charging station 40 is not reserved and the routine is terminated.

[0050] As described above, according to this embodiment, a notification is sent to the vehicle 10 when there are no longer a predetermined number of charging stations 40 within the notification distance, thereby making the user aware of the need for charging. In addition, the notification is sent to the user when there are still a predetermined number of movable charging stations 40 remaining, which increases the user's options. This improves user convenience.

[0051] <Other embodiments> The above-described embodiment is merely an example, and the present disclosure can be implemented with appropriate modifications within the scope that does not deviate from the gist of the disclosure.

[0052] The processes and means described in this disclosure can be freely combined and implemented as long as no technical contradiction occurs.

[0053] Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Alternatively, a process described as being performed by different devices may be executed by one device. In a computer system, the hardware configuration (server configuration) that realizes each function can be flexibly changed. For example, some of the functions of the server 30 may be provided in the vehicle 10 or the user terminal 20.

[0054] In the above embodiment, the vehicle 10 is used for car sharing, but the present invention is not limited to this and can be applied to any moving object that moves by receiving power from a battery. For example, the present invention can be applied to an electric kick scooter or an electric bicycle.

[0055] In the above embodiment, the charging notification is sent only once. However, this is not limiting. For example, the charging notification can be sent multiple times by changing the search conditions. For example, a notification can be output when the nearest charging station 40 that supports rapid charging is no longer within the notification distance, and then a second notification can be output when the nearest charging station 40 that supports normal charging is no longer within the notification distance. Also, for example, a notification can be output when the nearest charging station 40 that is available free of charge is no longer within the notification distance, and then a second notification can be output when the nearest charging station 40 that is available for a fee is no longer within the notification distance.

[0056] The present disclosure can also be realized by providing a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors in the computer read and execute the program. Such a computer program may be provided to the computer via a non-transitory computer-readable storage medium connectable to the computer's system bus or via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (e.g., a floppy disk, a hard disk drive (HDD), etc.), an optical disk (e.g., a CD-ROM, a DVD disk, a Blu-ray disk), a read-only memory (ROM), a random-access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, or any type of medium suitable for storing electronic instructions.
