Overview of the system according to the present disclosure
Systems according to various embodiments of the present disclosure manage the status of a vehicle having a charging state in which the vehicle is electrically connected to a charging station and charges a battery with power, and a running state in which the vehicle runs using the power stored in the battery. In particular, the system calculates a target remaining charge amount, which is the remaining charge amount required before a future scheduled run is made, based on information related to the vehicle's current remaining charge amount and information related to the charging capacity of the charging station. Then, when making a new run reservation for the vehicle on the terminal device, the system indicates to the user that a new run reservation for the vehicle is available, based on information indicating the calculated target remaining charge amount.

1 is a diagram showing an overview of an application executed by a system according to the present disclosure. Specifically, FIG. 1 shows an example of a reservation details screen displayed after the travel reservation application according to the present disclosure is started on a terminal device. According to FIG. 1, various information about the vehicle is displayed on the display 111 of the terminal device along with a photo 11 of the vehicle that is a candidate for travel reservation. As an example of the displayed information, basic information 12 of the vehicle is displayed. In addition to information about the vehicle usage cost and basic specifications of the vehicle, evaluation information 13 on the vehicle made by other users, etc. is displayed in this basic information 12. As an example of the displayed information, information 15 indicating the planned travel distance for this reservation and information 16 indicating the distance that can be traveled for this reservation are displayed. The information 15 indicating the planned travel distance for this reservation is distance information calculated based on the reservation time and the average speed during travel that is stored in advance for each vehicle. The information 16 indicating the distance that can be traveled for this reservation is information based on the target remaining charge amount at the start of the current travel reservation calculated by the charging management device. The target remaining charge amount is the remaining charge amount that is the target remaining charge amount for the travel of a travel reservation scheduled in the future (described in detail later). Another example of the information displayed is information 18 that indicates the percentage of the power that is supplied from so-called renewable energy sources among the power that is charged to the battery of the vehicle. By displaying such information, the user can make an environmentally friendly reservation. Another example of the information displayed is a reservation confirmation icon 17 that confirms the reservation of the vehicle.

In this disclosure, a vehicle can be any vehicle that is electrically connected to a charging station and has a charging state in which the battery is charged with power, and a running state in which the vehicle runs using the power stored in the battery. In the following embodiment, an example of a so-called electric vehicle is described as a vehicle, but this is of course not limited to this. For example, the system according to the present disclosure can be suitably applied to any vehicle that can run using electric power, such as two-wheeled vehicles such as bicycles and motorcycles, trains, buses, trucks, ships, and airplanes.

In addition, in this disclosure, a driving reservation application simply means an application that allows a vehicle driving reservation, and does not have to be an application dedicated to vehicle driving reservations. In other words, by executing the driving reservation application, various functions may be executed in addition to the driving reservation function, such as a driving reservation function for a hotel or the like other than the vehicle, a map function, and an advertisement display function.

1. Configuration of the system 1 according to the present disclosure Fig. 2 is a conceptual diagram illustrating a configuration of the system 1 according to the first embodiment of the present disclosure. Referring to Fig. 2, the system 1 includes at least a terminal device 100, a reservation management device 200, a vehicle 300, and a charging management device 400, which are connected to each other directly or indirectly via a network 500 so as to be able to communicate with each other.

The network 500 may be configured using wireless communication, wired communication, or a combination of these. In the example of FIG. 2, only one each of the terminal device 100, reservation management device 200, and charging management device 400 is shown, but it is of course possible to configure the network 500 using two or more devices. For example, the charging management device 400 can distribute its components and processes to multiple management devices. In addition, the system 1 can be connected to various databases as necessary and can execute various processes in conjunction with these.

The charging management device 400 is a device that manages the status of the vehicle 300, which is electrically connected at the charging station to charge the battery and has a charging state in which the battery is charged, and a running state in which the battery is used to run. The reservation management device 200 is a device that receives target remaining charge information and the like between the charging management device 400 and manages the reservation of the vehicle 300. The vehicle 300 transmits vehicle information and the like to the charging management device 400 via the reservation management device 200 by a communication interface mounted on the vehicle-mounted device. The terminal device 100 is a device that performs vehicle travel reservations and evaluates the vehicle 300, and transmits information about the inputted travel reservation to the reservation management device 200. Note that in FIG. 2, the vehicle 300 and the terminal device 100 are shown one each for convenience of explanation, but the charging management device 400 and the reservation management device 200 can naturally be connected to multiple vehicles and terminal devices. In addition, although the vehicle information and the like are transmitted from the vehicle 300 to the charging management device 100 via the reservation management device 200, the vehicle information and the like may be transmitted directly from the vehicle 300 to the charging management device 100 without going through the reservation management device 200.

2. Configuration of the terminal device 100 Fig. 3 is a block diagram showing an example of the configuration of the terminal device 100 according to the present disclosure. The terminal device 100 does not need to include all of the components shown in Fig. 3, and may have a configuration in which some components are omitted, or may include other components.

An example of the terminal device 100 is a portable terminal device capable of wireless communication, such as a smartphone. However, the present disclosure can also be suitably applied to any other device capable of executing the application according to the present disclosure, such as a feature phone, a personal digital assistant, a PDA, a laptop computer, or a desktop computer.

As shown in FIG. 3, the terminal device 100 includes a display 111, a processor 112, a sensor 113 including a GPS sensor 114, a communication interface 115 including a communication processing circuit 116 and an antenna, a memory 117 including a RAM, a ROM, or a non-volatile memory (or a HDD in some cases), and an input interface 118 including a touch panel 119 and hard keys 120. These components are electrically connected to each other via control lines and data lines.

The display 111 functions as a display unit that reads image information stored in the memory 117 in response to instructions from the processor 112 and displays various images (e.g., FIGS. 11A to 11C and 13A and 13B) generated by execution of the trip reservation application according to the present disclosure. The display 111 is, for example, a liquid crystal display or an organic EL display.

The input interface 118 is composed of a touch panel 119 and/or hard keys 120, and accepts instruction inputs from a user regarding the launch of a travel reservation application and reservations. The touch panel 119 is arranged to cover the display 111, and outputs position coordinate information corresponding to image data displayed on the display 111 to the processor 112. As a touch panel method, a known method such as a resistive film method, a capacitive coupling method, or an ultrasonic surface acoustic wave method can be used. In this embodiment, the touch panel 119 detects swipe operations and tap operations performed by an indicator.

The processor 112 is composed of a CPU (microcomputer) and functions as a control unit that controls other connected components based on various programs stored in the memory 117. Specifically, the processor 112 reads out from the memory 117 a program for executing the application according to this embodiment and a program for executing the OS, and executes them. In this embodiment, the processor 112 performs the following operations in particular: when it receives an instruction input from a user via the input interface 118, it transmits user information via the communication interface 115; receives vehicle information including information indicating a target remaining charge amount that is a target at the start of a future scheduled travel reservation for a vehicle extracted based on the user information; receives vehicle information including information indicating a target remaining charge amount that is a target at the start of a future scheduled travel for a vehicle extracted based on the user information, vehicle reservation schedule information, and evaluation information; outputs to the display 111 a display indicating that a new travel reservation for the vehicle is possible based on the received target remaining charge amount; outputs to the display 111 a display indicating whether a travel reservation for the vehicle is possible based on the received reservation schedule information; outputs to the display 111 information indicating the distance that can be traveled in the travel reservation based on the target remaining charge amount; outputs to the display 111 information indicating the amount of power supplied to the vehicle from a renewable energy source for charging. The processor 112 may be configured with a single CPU, or may be configured with multiple CPUs.

Memory 117 is composed of ROM, RAM, non-volatile memory, HDD, etc., and functions as a storage unit. ROM stores instructions for executing the application and OS according to this embodiment as a program. RAM is a memory used for writing and reading data while the program stored in ROM is being processed by processor 112. Non-volatile memory is a memory into which data is written and read by the execution of the program, and data written here is retained even after the execution of the program has ended. In this embodiment, the memory 117 stores programs for, among others, a process of transmitting user information via the communication interface 115 when the input interface 118 accepts a user's instruction input, a process of receiving vehicle information including information indicating a target remaining charge amount that is a target at the start of a future scheduled driving reservation for a vehicle extracted based on the user information, a process of receiving vehicle information including information indicating a target remaining charge amount that is a target at the start of a future scheduled driving reservation for a vehicle extracted based on the user information, vehicle reservation schedule information, and evaluation information, a process of outputting a display indicating that a new driving reservation for the vehicle is possible based on the received target remaining charge amount to the display 111, a process of outputting a display indicating whether a driving reservation for the vehicle is possible based on the received reservation schedule information to the display 111, a process of outputting information indicating the distance that can be driven in the driving reservation based on the target remaining charge amount to the display 111, and a process of outputting information indicating the amount of power supplied from a renewable energy source for charging the vehicle to the display 111.

The communication interface 115 functions as a communication unit that transmits and receives information between the reservation management device 200, the charging management device 400, and the vehicle 300 that are installed remotely via the communication processing circuit 116 and an antenna. The communication processing circuit 116 performs processing to receive a program for executing the travel reservation application according to this embodiment, various information used in the application, and the like from the reservation management device 200, the charging management device 400, and the vehicle 300 according to the progress of the application. It also performs processing to transmit the results of the execution of the application to the reservation management device 200 and the charging management device 400.

The communication processing circuit 116 processes based on a wideband wireless communication method such as the LTE method, but it is also possible to process based on a method related to narrowband wireless communication such as wireless LAN such as IEEE802.11 or Bluetooth (registered trademark). It is also possible to use wired communication instead of or in addition to wireless communication.

The sensor 113 includes a GPS sensor 114. The GPS sensor 114 detects the current location information of the terminal device 100 by communicating with multiple satellites. The detection of the current location information can be performed at a predetermined interval (for example, every three minutes). In this embodiment, the current location information detected by the sensor 113 may be coordinate information such as latitude and longitude in real space, or information that identifies an area formed in real space (for example, a city, ward, town, village, prefecture, etc.). In this embodiment, the GPS sensor 114 and the like are given as an example of the sensor 113, but this is not limiting. Information such as a WiFi access point or a base station of a wideband wireless communication can also be used as the current location information, and a communication processing unit capable of acquiring such information can also be used as the sensor 113.

3. Configuration of the charging management device 400 Fig. 4 is a block diagram showing an example of the configuration of the charging management device 400 according to the present disclosure. The charging management device 400 does not need to include all of the components shown in Fig. 4, and may have a configuration in which some components are omitted, or may include other components.

As shown in FIG. 4, the charging management device 400 includes a memory 411 including a RAM, a ROM, a non-volatile memory, an HDD, etc., a processor 412 including a CPU, etc., an output interface 413, and a communication interface 414. These components are electrically connected to each other via control lines and data lines.

The memory 411 includes a RAM, a ROM, a non-volatile memory, and a HDD, and functions as a storage unit. The memory 411 stores instructions for each process according to this embodiment and instructions for executing the OS as programs. Such programs are loaded and executed by the processor 412. The memory 411 also stores various information such as the vehicle information table shown in FIG. 5A, the station information table shown in FIG. 5B, the predicted remaining charge information table shown in FIG. 5C, and the reservation information table. In this embodiment, the memory 411 also stores a program for executing a process of calculating a target remaining charge amount, which is a target remaining charge amount before traveling in one or more travel reservations, based on electricity cost information indicating a distance that can be traveled per a predetermined unit of electricity, information indicating charging capacity, and schedule information, and a process of instructing to set a time frame for charging during a time period when there is a surplus of supplied electricity.

The processor 412 is composed of a CPU (microcomputer) and functions as a control unit for controlling other connected components based on various programs stored in the memory 411. In this embodiment, the processor 412 particularly performs a process of calculating a target remaining charge amount, which is a target remaining charge amount before driving in one or more driving reservations, based on electricity cost information indicating the distance that can be driven per predetermined unit of electricity, information indicating charging capacity, and schedule information, and a process of instructing to set a time frame for charging during a time period when there is a surplus of supplied electricity. The processor 412 may be composed of a single CPU, or may be composed of multiple CPUs.

The communication interface 414, as an example, performs processes such as modulation and demodulation to transmit and receive the program according to this embodiment, various information, and the like, via the network 500 with the reservation management device 200, the vehicle 300, and/or the terminal device 100. The communication interface 414 communicates with each of the above devices according to a known wireless communication method or a known wired communication method. In this embodiment, in particular, it receives vehicle information from the vehicle 300 and schedule information indicating the vehicle's travel reservation status from the reservation management device 200, and transmits information regarding the target remaining charge amount and updated schedule information to each device.

Although not specifically shown, the output interface 213 functions as an information input/output unit for inputting and outputting information to and from various external devices such as a printer or display. The output interface 213 can adopt any known connection format as desired, such as a serial port, a parallel port, or a USB.

5A is a diagram conceptually illustrating a vehicle information table stored in the charging management device 400 according to the first embodiment of the present disclosure. The information stored in the vehicle information table is received from the vehicle 300 as the processing progresses, updated, and stored in the memory 411.

According to FIG. 5A, the vehicle information table stores station ID information, current remaining charge information, power consumption information, renewable energy ratio information, and evaluation information in association with vehicle ID information. "Vehicle ID information" is information that identifies each vehicle using unique information assigned to each vehicle. "Station ID information" is information that is transmitted from a charging station when a vehicle is connected to a charging station, and is information that identifies the charging station to which the vehicle is connected. It is transmitted when the vehicle is currently connected to a charging station. "Current remaining charge information" is information that indicates the current remaining charge of each vehicle. "Power consumption information" is information that indicates the distance that can be traveled per a predetermined unit of power (e.g., 1 kWh). "Renewable energy ratio information" is information that indicates the proportion of the amount of power supplied from a renewable energy source to the amount of power that will be charged to the vehicle for future travel reservations. "Evaluation information" is information that indicates the results of evaluation of the vehicle based on evaluation information input by each user of the terminal device 100 when using the vehicle.

Figure 5B is a diagram conceptually illustrating a station information table stored in the charging management device 400 according to the first embodiment of the present disclosure. The information stored in the station information table is stored in advance in the memory 411.

According to FIG. 5B, the station information table stores charge amount information in association with station ID information. "Station ID information" is information that identifies each charging station using unique information assigned to each charging station. "Charge amount information" is information related to the charging capacity of each charging station. As an example, the charge amount per unit time (e.g., 40 kW) is used. The charge amount information is mainly used to calculate the target remaining charge amount.

Figure 5C is a diagram conceptually illustrating a predicted remaining charge information table stored in the charge management device 400 according to the first embodiment of the present disclosure. The information stored in the predicted remaining charge information table is updated and stored each time each value is calculated by the charge management device 400.

According to FIG. 5C, one predicted remaining charge information table is generated for each vehicle, i.e., for each vehicle ID. Then, target remaining charge information is stored for each specified time. "Target remaining charge information" is information that indicates the minimum remaining charge required at the start of a future scheduled trip reservation. Note that, as an example, the target remaining charge information is calculated for each period divided into two weeks at specified intervals.

Figure 5D is a diagram conceptually illustrating a reservation information table stored in the charging management device 400 according to the first embodiment of the present disclosure. The information stored in the reservation information table is received from the reservation management device 200, updated by the charging management device 400, and then transmitted back to the reservation management device 200 for management.

According to FIG. 5D, the reservation information table is a table that stores information indicating a reservation schedule for each vehicle, in association with each vehicle ID information, and stores the driving state, i.e., whether or not a driving reservation has been made, for each time period. The reservation information table is managed by the reservation management device 200, and a driving reservation is entered based on input from the vehicle user received by the terminal device 100. The reservation information table is then transmitted to the charging management device 400, and the period to be reserved for charging is updated and stored in the reservation information table based on a prediction of the future remaining charge amount, and is then transmitted again to the reservation management device 200. The time period for which the period to be reserved for charging is stored is a time during which users cannot make reservations for the vehicle.

5. Functions of the charging management device 400 Fig. 6 is a functional block diagram showing functions of the charging management device 400 according to the first embodiment of the present disclosure. Specifically, Fig. 6 is a diagram showing each function performed by the charging management device 400 having the configuration shown in Fig. 4 in cooperation with the reservation management device 200 and the like.

6, the charging management device 400 has the functional blocks of a memory unit 411, a communication unit 414, an output unit 413, and a control unit 412. Among these, the memory unit 411, the communication unit 414, and the output unit 413 correspond to the memory 411, the communication interface 414, and the output interface 413 shown in FIG. 4, and execute the functions of each component. For example, the communication unit 414 receives vehicle status information, vehicle information including information for identifying the vehicle (vehicle ID information), reservation schedule information, reservation processing information, etc. from the reservation management device 200. Here, the vehicle status information is information on the current status of the vehicle together with the vehicle ID information from each vehicle 300 received by the reservation management device 200, and is information indicating whether the vehicle is currently in a running state or a charging state. In addition, the reservation schedule information is information stored in the reservation information table in the reservation management device 200 in which the use reservation time slot for each vehicle is secured based on the input from the user of each terminal device 100. The reservation processing information is information related to a vehicle use reservation accepted via a reservation application or the like in each terminal device 100. The storage unit 411 stores vehicle status information, vehicle information, reservation schedule information, reservation processing information, and the like received by the communication unit 414.

Next, according to FIG. 6, the control unit 412 has the functional blocks of a remaining charge prediction unit 412a, a reservation schedule update unit 412b, and a charging time shift unit 412c. Among these, the remaining charge prediction unit 412a determines, based on the above information received from the reservation management device 200, that it is necessary to recalculate the target remaining charge amount when a new reservation for use of the vehicle is made (for example, when selection information in which the user selects a specific vehicle on the terminal device 100 is received), when a new reservation for use is made, or when it is determined that there is a large discrepancy between the actual measurement value of the remaining charge amount and the target remaining charge amount.

The remaining charge prediction unit 412a performs a process of predicting the target remaining charge based on the vehicle information and reservation schedule information received from the reservation management device 200 by the communication unit 414. Here, the vehicle information includes at least vehicle ID information, current remaining charge amount, and station ID information for each connected vehicle 300, and is received by the reservation management device from each vehicle at a predetermined timing.

The reservation schedule update unit 412b updates and stores the time to be secured as charging time in the reservation schedule information stored in the storage unit 411 based on the predicted target remaining charge amount. The charging time shift unit 412c performs processing to shift the scheduled charging time for the vehicle 300 to a time period when there is a surplus in the amount of power supplied (a period of surplus power generation) due to, for example, a larger supply from a renewable energy source, based on the target remaining charge amount calculated by the reservation schedule update unit 412b.

6. Processing flow performed by the charge management device 400 (target remaining charge amount prediction processing)
Fig. 7 is a diagram showing a processing flow executed in the charge management device 400 according to the first embodiment of the present disclosure. Specifically, the diagram shows functions mainly performed by the remaining charge amount prediction unit 412a and the reservation schedule unit 412b in Fig. 6. The processing flow is mainly performed by the processor 412 reading and executing a program stored in the memory 411 at a predetermined cycle (e.g., every 15 minutes).

According to FIG. 7, the processor 112 performs a process of reading information received from the reservation management device 200 and stored in the memory 411. Specifically, the processor 412 refers to the reservation information table of FIG. 5D to read reservation schedule information for the vehicle V1 (S101). Next, the processor 412 refers to the vehicle information table of FIG. 5A to read electricity cost information associated with the vehicle V1 (S102). Furthermore, the processor 412 refers to the vehicle information table of FIG. 5A and the station information table of FIG. 5B to read charging amount information associated with the station ID to which the vehicle V1 is connected (S103).

After reading out the information required for calculating the target remaining charge amount in S101 to S103, the processor 412 calculates the target remaining charge amount required at the end of each reservation registered in the reservation schedule information (S104). For example, reservation 3, which is the last reservation in the reservation schedule information, is scheduled from time t7 to t8. At this time, the processor 412 calculates the target remaining charge amount at the end of the reservation as "0". Next, the processor 412 calculates the target remaining charge amount required at the start of each reservation (S105). For example, reservation 3, which is the last reservation in the reservation schedule information, is scheduled from time t7 to t8. At this time, the processor 412 calculates the amount of power consumed in reservation 3 based on the reservation time and power consumption information, and calculates the target remaining charge amount required at the start of the travel reservation by adding the calculated power consumption amount to the target remaining charge amount at the end calculated in S104.

When the processor 412 calculates each target remaining charge amount for the last reservation (i.e., reservation 3), it calculates the target remaining charge amount at the end of the travel reservation and the target remaining charge amount at the start of the travel reservation for the reservation immediately before (e.g., reservation 2). First, the processor 412 calculates the amount of power that can be charged during the free time based on the free time between this reservation (i.e., reservation 2) and the reservation immediately after (i.e., reservation 3) and the charge amount (charging capacity) of the charging station, and calculates the target remaining charge amount at the end of the travel reservation by subtracting the calculated chargeable amount of power from the target remaining charge amount at the start of the travel of the reservation immediately after (i.e., reservation 3). Next, the processor 412 calculates the amount of power consumed in this reservation 2 based on the reserved time and power cost information, and calculates the target remaining charge amount required at the start of the travel reservation of reservation 2 by adding the calculated power consumption amount to the calculated target remaining charge amount at the end of reservation 2.

The processor 412 calculates the target remaining charge at the end and the target remaining charge at the start for all driving reservations in a similar manner. The processor 412 then stores the calculated target remaining charge at the start and end of each driving reservation in a predicted remaining charge information table in the memory 411. In this way, for example, focusing on reservation 1, which is the first reservation, the target remaining charge at the start of reservation 1 is calculated based on all of the amount of power consumed during the reservation time of reservation 3, the amount of power consumed during the reservation time of reservation 2, and the amount of power consumed during the reservation time of reservation 1.

When the processor 412 has finished calculating the target remaining charge amount at the start and end of each travel reservation in S104 and S105, it calculates the charging time required to ensure the target remaining charge amount at the start of each travel reservation (S106). Specifically, the processor 412 calculates the amount of power to be charged by the start of a travel reservation based on the target remaining charge amount at the end of the previous travel reservation (e.g., reservation 2) from the target remaining charge amount at the start of a travel reservation (e.g., reservation 3), and calculates the charging time by dividing the amount of power by the charging capacity. Then, the processor 412 sets the calculated charging time from the free time between both travel reservations (e.g., reservation 3 and reservation 2) as a charging frame and stores it as a charging frame in the schedule information table (S107). In addition, the processor 412 stores the target remaining charge amount at the end of the previous trip reservation as the target remaining charge amount at the start of charging, and the target remaining charge amount at the start of the next trip reservation as the target remaining charge amount at the end of charging, in the predicted remaining charge amount information table in the memory 411, for the set charging frame.

The above process calculates the target remaining charge amount, which is the target remaining charge amount before the planned future trip. Note that in S105, the target remaining charge amount at the start of the reservation is calculated using the electricity consumption information, but it is also possible to use information such as the average speed of the vehicle in addition to or instead of this information.

7. Processing flow performed by the charging management device 400 (reservation schedule update processing)
FIG. 8 shows target remaining charge amounts at the start and end of reservation 1, reservation 2, and reservation 3 scheduled for future times t0 to t9 for vehicle ID information "V1" according to the process flow of FIG.

Focusing on the target remaining charge curve K1 in FIG. 8, for example, the target remaining charge will be zero at the end of reservation 2. Therefore, processor 412 updates the reservation schedule information to input "charging" so that the next period, time t6 to t7, will always be in a charging state. Also, the target remaining charge at the start (t3) of reservation 2 is almost the full amount of the battery. On the other hand, the target remaining charge at the end (t2) of the previous reservation 1 is almost half the amount. Therefore, since the amount of charge required for the next reservation 2 cannot be secured at the end of previous reservation 1, processor 412 updates the reservation schedule information to input "charging" so that the time t2 to t3 after the end of reservation 1 will be a charging field.

For example, if the target remaining charge amount after the end of reservation 1 exceeds the target remaining charge amount at the start of the next reservation 2, the time between t2 and t3 does not need to be reserved as charging time. Therefore, in such a case, the processor 412 reserves the time equivalent to the surplus as a time during which further travel reservations can be made, rather than as charging time. In this way, the charging state of the reservation schedule information and whether or not a travel reservation can be made are determined based on the calculated target remaining charge amount.

8. Processing flow performed by the charge management device 400 (charging time shift processing)
FIG. 9 is a diagram showing a process flow executed in the charging management device 400 according to the first embodiment of the present disclosure. Here, due to the recent increase in environmental awareness, renewable energy sources such as solar power supplied to charging stations have been attracting much more attention than energy sources such as nuclear energy sources and carbon energy sources such as coal and oil. Many houses and office buildings are equipped with renewable energy power generation facilities, and technologies and services for storing the electricity generated there in batteries installed there have been developed. As a result, charging stations are usually supplied with energy from power plants that generate electricity using coal, oil, nuclear power, etc., but it is also possible to receive electricity from batteries that store electricity generated by renewable energy sources installed in houses, office buildings, etc. separately from this. Therefore, in FIG. 9, it is possible to instruct the charging time for the vehicle 300 that was initially scheduled to be shifted to a time period (period of surplus electricity generation) when there is a surplus in the amount of electricity supplied, for example, because the supply from the renewable energy source is greater, based on the calculated target remaining charge amount. That is, the charging time shifting process is a process of shifting the charging time to a time period when there is a surplus of supplied power (a surplus power generation period), for example, when there is a supply of power from a renewable energy source.

Figure 9 shows a processing flow performed by the charging management device 400 in the charging source switching process shown in Figure 6. This processing flow is performed at a predetermined interval (e.g., every 15 minutes) mainly by the processor 412 reading and executing a program stored in the memory 411.

First, the processor 412 receives from the outside and stores an excess power information table that stores predictions of the amount of excess power in batteries installed in structures (e.g., houses, office buildings, etc.) electrically connected to the charging station. Then, it determines whether or not there is a period of excess power in the battery linked to the station ID information of the charging station to which the vehicle 300 to be charged is connected (S201).

Next, if there is a period of surplus power generation, the processor 412 determines the priority order between the vehicles consuming the surplus power (S202). Specifically, based on the charge amount (the amount of power that can be charged per unit time: usually stored in the vehicle information table of FIG. 5A or the like) registered in advance for each vehicle and the length of the chargeable time of each vehicle during the period of surplus power generation (i.e., the period during which each vehicle is not in a running state in the reservation schedule information of each vehicle updated based on the target remaining charge amount), the priority order for each vehicle is determined so that renewable energy sources are preferentially allocated to vehicles that can be charged a large amount during the period of surplus power generation.

Next, the processor 412 assigns a schedule to supply power during the surplus power generation period according to the determined priority (S203). The processor 412 then calculates the target remaining charge amount again, assuming that a renewable energy source will be used for the assigned period, again in the process flow shown in FIG. 7 (S204). As a result, if it is determined that the target remaining charge amount can be secured at the start of the next reservation even if charging from a renewable energy source is not performed for the entire assigned surplus power generation period, the processor 412 corrects the reservation schedule to assign the remaining charge amount to a vehicle with the next priority (S205). The processor 412 determines a charging schedule for the vehicle to be shifted to the surplus power generation period and charged, and instructs the charging station to charge according to the determined charging schedule (S206).

Next, based on the determined allocation of renewable energy sources, processor 412 calculates the proportion of the amount of power supplied from the renewable energy source to the amount of power to be charged for future travel reservations in each vehicle. For example, assume that as a result of the determined allocation of renewable energy sources, charging from the renewable energy source is allocated between times t6 and t7 shown in FIG. 8. In this case, at the start of reservation 3, the charge amount of the renewable energy source is calculated by multiplying the charge amount by the charging time by the renewable energy source (times t6 to t7). Then, the proportion of the charge amount of the renewable energy source to the target remaining charge amount at the start of reservation 3 is calculated. The calculated proportion is then stored in the vehicle information table shown in FIG. 5A as the proportion at the start of reservation 3.

In this way, when there is a period of surplus power generation at the charging station, it is possible to shift the charging time based on the target remaining charge amount so that charging that would normally be performed outside the surplus power supply period is performed within the surplus power supply period. Note that in the above example, the charging time is shifted to the surplus power supply period, which has a high proportion of so-called renewable energy sources, taking the environment into consideration, but the charging time may also be shifted from the perspective of cost, charging efficiency, etc.

9. Processing flow performed by the terminal device 100 (processing related to vehicle travel reservation)
Fig. 10 is a diagram showing a processing flow executed in the terminal device 100 according to the present disclosure. Specifically, Fig. 10 shows a processing flow executed after a user starts a travel reservation application in the terminal device 100. This processing flow is executed mainly by the processor 112 reading and executing a program stored in the memory 117 at a predetermined period.

First, the processor 112 determines whether a command input from the user to start the trip reservation application has been received via the input interface 118 and whether the application has been started (S301). The trip reservation application is started, for example, by clicking the start icon of the application on the standby screen of the terminal device 100 via the touch panel 119. When the trip reservation application is started, the processor 112 transmits user information including the user ID information of the user initially registered in the application and the current location information of the terminal device 100 detected by the GPS sensor 114 or the like to the reservation management device 200 (S302).

Although not shown in the figure, the reservation management device 200 that has received the user information extracts vehicles that are being charged at charging stations that exist within a radius of, for example, 5 km based on the received current location information. The reservation management device 200 then receives and stores reservation schedule information for each vehicle after a charging slot is secured in the charging management device 400 based on the target remaining charge amount, and extracts reservation schedule information corresponding to the vehicle ID information of the extracted vehicle from the reservation schedule information. The reservation management device 200 also receives and stores a vehicle information table after the renewable energy ratio information and evaluation information have been updated from the charging management device 400, and extracts renewable energy ratio information and evaluation information corresponding to the vehicle ID information of the extracted vehicle from the vehicle information table. The reservation management device 200 also receives and stores a predicted remaining charge information table calculated for each vehicle from the charging management device 400, and extracts target remaining charge information corresponding to the vehicle ID information of the extracted vehicle from the vehicle information table. The reservation management device 200 then transmits the extracted information to the terminal device 100 as extracted vehicle information.

The processor 112 of the terminal device 100 controls the terminal device 100 to receive the extracted vehicle information extracted as described above via the communication interface 115 (S303). The received extracted vehicle information is stored in the memory 117 in association with each vehicle ID information. The processor 112 then controls the terminal device 100 to display the extracted vehicle information on the display as a list of available vehicles based on the stored information so that the user can view it (S304).

Here, FIG. 11A is a diagram showing an example of a screen displayed on the terminal device 100 according to the present disclosure. Specifically, FIG. 11A is a diagram showing an example of a list screen of vehicles extracted as available vehicles. According to FIG. 11A, a vehicle panel 24 including information on vehicles extracted based on location information in the reservation management device 200 is displayed in a list form on the display 111. In addition to information on the vehicle usage cost and basic specifications of the vehicle, the vehicle panel 24 displays evaluation information on the vehicle by other users, etc., allowing the user to easily select the desired vehicle.

The evaluation information for each vehicle is calculated based on the evaluation information entered by the user of the vehicle (details of the process related to entering evaluation information will be described later). For example, the total points for the evaluation results for each item entered by each user are calculated, the average of all the total points is calculated, and the vehicle is classified into five levels, "dirty," "slightly dirty," "average," "clean," and "very clean," based on the average. The above methods and the examples of vehicle evaluation information displayed are merely examples, and evaluation information calculated by other methods may also be used.

In the example of FIG. 11A, a case where three vehicle panels 24 are displayed has been described, but one or three or more may be displayed. If they cannot be displayed all at once on the display 111, the input interface 118 may accept input of a scroll command to display them sequentially. The extracted vehicle information does not necessarily need to be displayed in a list, and may be displayed as a map in which the positions of each vehicle are plotted on a map centered on the current location of the terminal device 100, for example.

Returning again to FIG. 10, when the input interface 118 receives an instruction input for selecting a desired vehicle from the vehicle list shown in FIG. 11A, the processor 112 controls the display 111 to perform a series of displays to confirm the selection of the vehicle to be reserved (S305).

FIGS. 11B and 11C are diagrams showing examples of screens displayed on the terminal device 100 according to the present disclosure. Specifically, FIG. 11B is a screen for inputting a travel reservation time for a desired vehicle after selecting the vehicle from the vehicle list displayed in FIG. 11A. Also, FIG. 11C is a screen showing reservation details information that is displayed after inputting a travel reservation time, etc. on the screen of FIG. 11B.

According to FIG. 11B, a reservation status display 26 is displayed on the display 111 based on the reservation schedule information included in the extracted vehicle information. The reservation status display 26 distinguishes between already reserved slots, charging slots secured based on the calculated target remaining charge, and reservation-available slots allocated based on the calculated target remaining charge. The display 111 also displays an input box 27 for the desired usage time. The desired start time and end time of usage are input into the input box 27 by the input interface 118 accepting instructions input by the user. The display 111 also displays a reservation icon 28 that accepts a reservation request from the user.

Here, the processor 112 refers to the reservation schedule updated based on the target remaining charge amount, determines whether the desired use time entered in the input box 27 is included in the available reservation time slot, and activates the reservation icon 28 only if it is included. Specifically, if the input desired use time is not included in the available reservation time slot, the processor 112 highlights the reservation icon 28, for example, in gray to visually indicate that the user cannot make a reservation. On the other hand, if the input desired use time is included in the available reservation time slot, the processor 112 highlights the reservation icon 28, for example, in blue to visually indicate that the user can make a reservation. Then, when the input interface 118 accepts a user's instruction input for the activated reservation icon 28, the processor 112 controls the display 111 to display the screen shown in FIG. 11C.

According to FIG. 11C, a reservation details screen is displayed on the display 111. Specifically, the display 111 displays basic information 12 of the vehicle together with a photo 11 of the vehicle that is a candidate for the travel reservation. This basic information 12 displays evaluation information included in the extracted vehicle information, the vehicle usage unit price, information on the basic specifications of the vehicle, and the like. The evaluation information displayed on the screen is the same as the evaluation information displayed on the screen shown in FIG. 11A. In addition, the display 111 displays information 15 indicating the planned travel distance for the current reservation and information 16 indicating the distance that can be traveled for the current reservation. The information 15 indicating the planned travel distance for the current reservation is information on the distance calculated based on the reservation time and the average speed during travel that is stored in advance for each vehicle. The information 16 indicating the distance that can be traveled for the current reservation is information based on the target remaining charge amount at the start of the current travel reservation. In addition, the display 111 displays information 18 indicating the proportion of electricity supplied from renewable energy sources based on the renewable energy ratio information included in the extracted vehicle information. By displaying in this manner, the user can make an environmentally friendly reservation. In addition, a reservation confirmation icon 17 that confirms the reservation of the vehicle is displayed on the display 111. When the input interface 118 accepts the user's instruction input to the reservation confirmation icon 17, the processor 112 proceeds to the subsequent processing.

Returning to FIG. 10 again, when the input interface 118 accepts a user's instruction input to the reservation confirmation icon 17 on the screen shown in FIG. 11C, the processor 112 transmits the reserved vehicle information to the reservation management device 200 (S306). The reserved vehicle information includes the vehicle ID information of the vehicle selected in FIG. 11A and the desired use time information input in FIG. 11B. The reservation management device 200 then determines whether the reservation can be confirmed based on the received reserved vehicle information, and if so, transmits the reservation confirmation information to the terminal device 100.

When the processor 112 of the terminal device 100 receives the reservation confirmation information (S307), it displays on the display 111 a message indicating that the reservation has been confirmed (S308). Although this display is not particularly shown in the figure, it may be a pop-up display on the display 111, or it may be a notification by email or the like and displayed on the email screen. This completes the process related to the trip reservation performed by the processor 112 of the terminal device 100.

10. Processing flow performed by the terminal device 100 (input processing of evaluation information, etc.)
In the present disclosure, as described above, evaluation information for each vehicle is displayed on the screen displayed at the time of reservation. The evaluation information is calculated based on the evaluation information for each item input by each user when the user finishes using the vehicle as described above. Fig. 12 is a diagram showing a processing flow executed in the terminal device 100 according to the present disclosure. Specifically, Fig. 12 shows a processing flow performed in the terminal device 100 when the user finishes using the vehicle and inputs evaluation information. The processing flow is performed by the processor 112 mainly by reading and executing a program stored in the memory 117 at a predetermined cycle.

First, the processor 112 determines whether a command input from the user to start the travel reservation application is accepted at the input interface 118 and the application is started (S301). When the travel reservation application is started, the processor 112 determines whether the input interface 118 has accepted the selection of a lock icon (S402). If it is determined that the selection of the lock icon has been accepted, the processor 112 displays the vehicle evaluation items and return check items (S403). The processor 112 then accepts input of the user's evaluation information for the displayed vehicle evaluation items and return check items via the input interface 118 (S404).

13A and 13B are diagrams showing examples of screens displayed on the terminal device 100 according to the present disclosure. Specifically, FIG. 13A shows an example of a screen for displaying vehicle evaluation items and inputting an evaluation of each item. According to FIG. 13A, questions 20 related to each evaluation item, such as "1. How clean is the vehicle before boarding?" and "How clean is the vehicle when it is returned?" are displayed on the display 111. The questions are generated by receiving questions linked to the vehicle ID information of the used vehicle from the reservation management device 200 in advance. In addition, an input area 19 for inputting the user's evaluation of the question is displayed below each question 20. In the example of FIG. 13A, the user can input a five-level evaluation by highlighting a star icon via the input interface 118. In addition, a send icon 21 for sending the input evaluation information to the reservation management device 200 is displayed on the display 111. At this time, the processor 112 highlights the send icon 21, for example, in gray until all the evaluation information is input, to visibly display that the user cannot send yet.

Also, according to FIG. 13B, the display 111 displays each return check item 22 for the user, such as "Have you left anything in the vehicle?" and "Has the interior been cleaned?". A check result input icon 23 for inputting the check result is displayed below each check item 22. In the example of FIG. 13B, the user can select the check result by tapping the check result input icon, "Yes" or "No," via the input interface 118. Once the evaluation information for the vehicle evaluation items shown in FIG. 13A and the check results for the return check items shown in FIG. 13B have all been entered, the send icon 21 is highlighted, for example, in blue to visually indicate that the user can make a reservation.

Returning to FIG. 12 again, when the input interface 118 receives a command input from the user to the send icon 21, the processor 112 controls the reservation management device 200 to send the evaluation information and check results via the communication interface 115 (S405).

Next, based on the transmission of the evaluation information and check results, the processor 112 proceeds to the process of ending use of the vehicle. Specifically, in order to lock the doors of the used vehicle, the processor 112 transmits locking instruction information to the vehicle 300 via the communication interface 115. Then, until locking completion information is received from the vehicle 300, the processor 112 controls the display 111 to display "locked". When the processor 112 receives the locking completion information from the vehicle 300, it controls the transmission of usage completion information indicating that usage has been completed to the reservation management device 200. This completes the process related to the input of evaluation information.

In this way, in the present disclosure, unless evaluation information is input, the vehicle cannot be locked and usage cannot be completed. This makes it possible to collect a large amount of evaluation information. Note that input of evaluation information is optional, and it is also possible to skip input of evaluation information and perform locking processing. When inputting this evaluation information, input for the return check items when returning the vehicle is also accepted. This prevents the user from forgetting to complete the items indicated in the return check items when returning the vehicle, and makes it possible to prevent problems that may result from this.

11. Others In the above, the case where reservation schedule information, electricity cost information, etc. are used in the calculation of the target remaining charge amount has been described. However, each of these pieces of information can be generated by various methods and procedures, not limited to the methods specifically mentioned above. For example, the reservation schedule information can be created by referring to the past usage history of each vehicle in addition to the usage reservation input by the user in advance, and taking into account the usage prediction for a predetermined future period from the usage history. Specifically, the charging management device 400 refers to the reservation schedule information of the vehicle for a certain past period (for example, the same period in the past 10 years) in addition to the reservation schedule information for a predetermined future period received from the reservation management device 200. Then, even if the usage record that was input with a certain probability or more during the same period in the past 10 years is not registered in the reservation schedule information received from the reservation management device 200, it is registered in the reservation schedule information as "reservation". The target remaining charge amount is calculated according to the reservation schedule information updated in this way. Furthermore, it is also possible to update the reservation schedule information using a learning device that has been machine-learned to learn the past usage history, the day of the week on which the vehicle was used, the weather, etc. as learning data.

Furthermore, instead of or in addition to the electricity cost information, it is also possible to refer to past driving history and calculate the amount of power that is expected to decrease during a reservation for driving from the driving history. Specifically, the charging management device 400 stores driving history information of the vehicle used for a certain period of time in the past (e.g., the past 10 years) for each user. Examples of driving history information include average speed at the time of use, weather, outside temperature, driving time, degree of acceleration/deceleration, etc. Then, based on this information, the electricity cost information is weighted, and a target remaining charge amount is calculated based on the weighted electricity cost information. In addition, the target remaining charge amount may be calculated using a learning device that has been machine-learned to use the driving history information as learning data.

As described above, this embodiment enables reservations for trips to be made based on a prediction of the remaining charge of each vehicle in the future, making it possible to realize a reservation system that is more convenient for users.
