(Embodiment)
Hereinafter, preferred embodiments of the terminal device, the energy supply device, the server device, the navigable range display method, the navigable range display program, and the recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an example of a functional configuration of a terminal device according to an embodiment. The terminal device (terminal) 101 is an electronic device on which a rechargeable battery is mounted and which is mounted on a mobile body (vehicle) in which the battery drives a power source. Further, the terminal 101 may be an electronic device that is carried by the user and moves with the vehicle.

The terminal 101 has an input unit 102, an acquisition unit 103, a display control unit 104, and a display unit 105.

The input unit 102 can input the virtual storage amount of the battery that drives the power source of the vehicle by user operation. The virtual storage amount is the amount of charge when the battery is charged in the state before (currently) the actual charge of the battery. For example, when the current storage amount (storage rate) is 30% and 50% is input as the disguised storage amount, the battery is actually charged by 20% later.

The acquisition unit 103 acquires the navigable range of the moving body according to the virtual storage amount input by the input unit 102. For example, the range (map image) on the map that can be reached with the virtual storage amount (storage rate) of 50% with respect to the current position of the vehicle is acquired. This navigable range can be acquired, for example, by a server communicatively connected to the terminal 101 performing arithmetic processing and responding to the terminal 101. Further, it is also possible for the terminal 101 to calculate and obtain the navigable range without providing a server. The display control unit 104 displays a map image including the current battery storage amount, the disguised storage amount of user operation input to the input unit 102, and the navigable range acquired by the acquisition unit 103 on the display unit 105. Take control.

Further, the acquisition unit 103 can acquire the expected charging waiting time until the virtual storage amount is reached, in addition to the navigable range of the vehicle according to the virtual storage amount. The expected charging waiting time is calculated by the server or the charging device for charging the battery based on, for example, the current storage amount of the battery, the virtual storage amount, and the charging speed for each charging mode. In this case, the display control unit 104 can display the expected charge waiting time on the display unit 105 in conjunction with the virtual storage amount.

Further, the terminal 101 has a reception unit 106, a transmission unit 107, a reception unit 108, and a search unit 109. In addition, the terminal 101 may have a charging unit 110 for charging the battery of the vehicle.

The reception unit 106 receives an operation of setting the virtual storage amount as the target storage amount when the image including the navigable range corresponding to the virtual storage amount input by the input unit 102 is displayed on the display unit 105. For example, the reception unit 106 can be configured by a decision button on the display unit 105. When the target storage amount is set, the transmission unit 107 transmits the target storage amount to the external device 111 mounted on the vehicle. The external device 111 is an in-vehicle device, a server, a charging device, or the like that manages the amount of electricity stored in the battery of the vehicle.

Further, the receiving unit 108 receives the charging completion information transmitted by the external device 111 when the stored amount of the battery of the vehicle reaches the target stored amount. The receiving unit 108 can also receive the current position information of the vehicle. The current position of the vehicle can be detected by, for example, an in-vehicle device which is an external device 111 by GPS or the like. In addition, if the terminal 101 has a GPS function or the like, the current position of the vehicle can be detected inside the terminal 101.

The search unit 109 searches for facilities (for example, charging facilities, stores, parking lots, etc.) existing around the vehicle based on the current position of the vehicle. In this case, the display control unit 104 can display the facility searched by the search unit 109 on the display unit 105 by superimposing it on the navigable range.

Further, the terminal 101 may include a charging unit 110 for charging the battery of the vehicle. For example, when the charging unit 110 is provided in the charging facility (charging device), each component of the terminal 101 shown in FIG. 1 can be provided in the charging device. Further, the terminal 101 may be configured to have only a function of receiving and displaying only the charging completion notification.

As described above, as a system configuration for displaying the navigable range, a configuration including a terminal 101, a server, and a charging device of a charging facility can be considered. Further, if the terminal 101 calculates the above-mentioned server functions, for example, the navigable range and the expected charging waiting time, it is not necessary to provide a server. Further, the charging device of the charging facility may have the function of the terminal 101 and may display a map image on which the navigable range of the vehicle is superimposed when charging connected to the vehicle.

FIG. 2 is a flowchart showing an example of a processing procedure for displaying the navigable range based on the virtual storage amount according to the embodiment. The processing of FIG. 2 is executed by the terminal 101, but the terminal 101 is not limited to the terminal 101, and a server or a charging device may execute a part of the processing (calculation processing or the like).

First, the terminal 101 displays the current storage rate of the battery on the display unit 105 (step S201). At this time, the acquisition unit 103 of the terminal 101 acquires the navigable range that can be reached with the current storage rate, and displays the map on the display unit 105.

Next, it waits for the user to input the virtual storage amount (step S202). The user inputs the virtual storage amount of the battery from the input unit 102. As a result, the acquisition unit 103 of the terminal 101 acquires the navigable range that can be reached by the virtual storage amount and displays the map on the display unit 105 (step S203). The virtual storage amount input from the input unit 102 can be changed stepwise or continuously and is displayed on the display unit 105.

The navigable range corresponding to the stored amount of the battery can be obtained by, for example, the technology disclosed in International Publication No. 2013/125019. For example, it is possible to indicate the navigable range on a map by finding a plurality of points that can be reached from the current position by the amount of electricity stored in the battery using a predetermined energy consumption calculation formula and combining these points. ..

At this time, the terminal 101 can search for facilities by genre by the search unit 109, search for facilities desired by the user, and display a map on the display unit 105. As a result, the search result of the facility desired by the user can be displayed. At this time, the user can change the virtual storage amount to be input to the input unit 102 so that the position of the desired facility is within the navigable range. As a result, it becomes possible to obtain a virtual storage amount for reaching the desired facility.

As described above, the navigable range can be displayed on the map by inputting the virtual storage amount in the state before the battery is actually charged. At this time, since the navigable range can be displayed according to the virtual storage amount, it is possible to obtain the virtual storage amount for reaching the desired facility, for example. After that, the user can actually charge the battery corresponding to the determined virtual storage amount, so that the user can travel to the desired facility or navigable range. In this way, even if a clear destination is not decided, the target storage amount for the vehicle battery can be clearly determined, and even if the destination is ambiguous, it is possible to appropriately determine how much charge should be performed. You will be able to do it.

The virtual storage amount can be input at any place, but for example, by inputting the virtual storage amount in the state immediately before the vehicle arrives at the charging facility and charges the vehicle, it is the current position of the vehicle. It is possible to display the navigable range based on the charging facility.

(Regarding the designation of virtual storage amount)
FIG. 5 is a diagram illustrating a designated state of the virtual storage amount in the first embodiment. A display example displayed on the display 414 by the display control unit 412 of the mobile terminal 401 is shown. FIG. 5A shows a map display of the navigable range based on the current amount of electricity stored. The mobile terminal 401 receives the navigable range data from the server 402 and displays the navigable range D1 on the display 414 as a map. In the figure, Δ is the current position d1 of the vehicle 400.

A storage amount display area 501 is provided at a lower position of the display 414. The current battery storage rate acquired by the storage rate acquisition unit 431 of the vehicle-mounted device 403 is output to the mobile terminal 401 via the server 402. The mobile terminal 401 displays the current storage rate at the slider 502 position in the storage amount display area 501 of the display 414. The state shown in FIG. 5A indicates that the slider 502 has a current storage rate of 30%. The position of the slider 502 can be changed continuously or stepwise (for example, in units of 10%) by the user operation, and the slider 502 is slid and moved by the user operation to reduce the virtual storage amount (designated storage rate). Be changed.

When the slider 502 is slid to a position of 40%, for example, as shown in FIG. 5B, it is possible to navigate in the storage amount display area 501 of the display 414 at the slider 502 position corresponding to the virtual storage amount of 40%. The range D2 is displayed. This navigable range D2 is displayed by transmitting 40% of the virtual storage amount to the server 402 and then receiving the navigable range data from the server 402.

Then, the user confirms that the destination (facility) to be reached is included in the navigable range D2 based on the change state of the navigable range D1 and D2, and the virtual storage amount at this time is specified as the charge amount. Set with the enter button 503.

The charge amount designation determination button 503 corresponds to the function of the reception unit 106 shown in FIG.

Further, when the virtual storage amount is set, the user searches for a desired destination (facility) and displays the destination (facility) of the search result on the display 414, so that the target is within the navigable range D2. The slider 502 can be slid by a predetermined amount so as to include the ground (facility). The destination (facility) search process is executed by the server 402 using the map DB423, for example, a list of destination (facility) candidates for each genre is transmitted to the mobile terminal 401, and the mobile terminal 401 selects the destination (facility). The server 402 searches and executes by selecting from the candidate list.

In FIG. 5, an example of increasing the storage rate with respect to the current storage rate has been described, but the virtual storage amount can be set lower than the current storage rate. In this case, it becomes possible to display the navigable range (a range narrower than the current navigable range D1) when the virtual storage amount is lower than the current storage rate without charging the battery with the current storage rate. ..

(Processing example of Example 1)
Next, an example of calculation processing of the navigable range based on the virtual storage amount according to the configuration example of the first embodiment will be described. FIG. 6 is a flowchart showing a processing content for displaying the navigable range based on the virtual storage amount according to the first embodiment.

FIG. 6 shows each process performed by the mobile terminal 401, the server 402, and the in-vehicle device 403 shown in FIG. In the first embodiment, the server 402 calculates the range that can be reached by the storage rate selected by the mobile terminal 401, and the user determines the storage rate to the server 402 while viewing the image of the navigable range on the mobile terminal 401. This is a configuration example for notifying and notifying the in-vehicle device 403 of the completion of charging. Then, in the example of FIG. 6, an example in which the processing is started in a state where the vehicle 400 reaches the charging facility where the battery can be charged is described, and in the following description, it will be described in the order in which each device performs in almost time series.

First, the vehicle-mounted device 403 determines whether the vehicle 400 has stopped at the charging facility by the current position acquisition unit 433 (step S601). If the on-board unit 403 stands by if it has not reached the charging facility (step S601: No loop) and stops at the charging facility (step S601: Yes), the vehicle identification information, current position, and storage rate acquisition unit of the vehicle 400 The storage rate acquired by 431 is transmitted to the server 402 (step S602). After that, the vehicle-mounted device 403 monitors the change in the storage rate (step S603). The determination in step S601 may be triggered by the start of charging the vehicle battery.

On the other hand, the mobile terminal 401 is in a state of waiting for activation of the storage rate setting application in the initial state (step S604: No loop). When the storage rate setting application is activated (step S604: Yes), the storage rate setting application transmits the personal identification information of the user of the mobile terminal 401 to the server 402 (step S605).

The server 402 receives the vehicle identification information, the current position, and the storage rate of the vehicle 400 from the vehicle-mounted device 403 (step S606), and receives the personal identification information from the mobile terminal 401 (step S607). Then, the server 402 determines whether the vehicle identification information and the personal identification information are associated with each other (step S608). In this process, it is determined whether or not the user and the vehicle are registered in the server 402 in advance. If there is no association between the vehicle identification information and the personal identification information (step S608: No loop), the service is set to standby in the example of FIG. 6, but since the service is not registered, the following service (navigable range based on the virtual storage amount) It may be a process that does not perform the presentation service). If there is an association between the vehicle identification information and the personal identification information (step S608: Yes), the process proceeds to step S613.

After executing step S605, the mobile terminal 401 sets the virtual storage amount and performs display processing of the navigable range corresponding to the virtual storage amount (steps S609 to S612). Further, after the execution of step S608, the server 402 performs arithmetic processing of the navigable range corresponding to the virtual storage amount (steps S613 to S615).

The server 402 calculates the navigable range when the storage rate is N% (current storage rate) based on the current storage rate transmitted from the on-board unit 403 by the navigable range estimation software 422 (step S614), and navigates. The possible range data is transmitted to the mobile terminal 401 (step S615). The mobile terminal 401 displays the navigable range on the map data when the storage rate transmitted from the server 402 is N% (step S610). In this state, the navigable range D1 shown in FIG. 5A is displayed on the mobile terminal 401.

After that, when the designated storage rate is changed (step S611: change) by the user operation (slider operation) of the virtual storage amount setting in the mobile terminal 401, the mobile terminal 401 transfers the changed storage rate to the server 402. Transmit (step S609). The server 402 acquires the storage rate parameter N% based on the changed storage rate by the mobile terminal 401 (step S613), calculates the navigable range when the changed storage rate (N%), and calculates the navigable range (step S614). The navigable range data when the storage rate is N% is transmitted to the mobile terminal 401 (step S615). In this state, the navigable range D2 at the time of changing the storage rate to N% is displayed on the mobile terminal 401.

After that, when the user determines the virtual storage amount and the charge amount designation button is operated on the mobile terminal 401 (step S611: determination), the mobile terminal 401 sets the determined virtual storage amount (designated storage rate) on the in-vehicle device. It is transmitted to 403 (step S612). The mobile terminal 401 may transmit this designated storage rate to the vehicle-mounted device 403 via the server 402.

When the in-vehicle device 403 receives the designated storage rate from the mobile terminal 401 (step S616), the in-vehicle device 403 starts charging the battery by the charging equipment and waits until the storage rate reaches the designated storage rate (step S617: No loop). When the storage rate reaches the designated storage rate (step S617: Yes), charging is stopped and the notification that the designated storage rate has been reached is transmitted to the mobile terminal 401 (step S618). The mobile terminal 401 notifies the user by displaying or the like that the designated storage rate has been reached (step S619), and ends the series of the above processes. The charging equipment can also start charging in step S603, assuming that the stopped vehicle is charged with a battery.

Further, the navigable range estimation software 422 of the server 402 is unique in the calculation of the navigable range in step S614, which is the basic data held corresponding to the vehicle type included in the vehicle identification information or the unique identification by the vehicle ID. By using the basic data stored as the past travel history of the vehicle, it is possible to calculate the navigable range with high accuracy.

Further, in the above processing example, the server 402 calculates the navigable range every time the storage rate parameter is changed, but from the beginning, a plurality of navigable ranges in 10% steps are calculated. Navigable range data may be transmitted to the mobile terminal 401. As a result, when the storage rate is changed on the mobile terminal 401, the navigable range can be quickly displayed. In this case, even if the user does not slide the slider 502, the display can be performed in the continuous display mode in which a plurality of navigable ranges of 10% steps can be displayed in the animation expression.

The map data for displaying the navigable range as a map is stored in the mobile terminal 401 in advance, and the display control unit 412 can superimpose and display the navigable range transmitted from the server 402 on the map data. Further, the map image on which the navigable range is superimposed can be downloaded from the server 402 to the mobile terminal 401.

In addition, the expected charging waiting time may be displayed in conjunction with the storage amount parameter. For example, when the current storage amount is 30% and the designated storage amount is 50%, one hour is displayed as the expected charging waiting time corresponding to the charging amount of 20%. In this case, the mobile terminal 401 calculates and processes the expected charging waiting time required for charging in the charging equipment according to the storage rate transmitted to the in-vehicle device 403. Further, the charging equipment may be configured to transfer the expected charging time to the mobile terminal 401 via the in-vehicle device 403. Further, the charge may be displayed in conjunction with the storage amount parameter. For example, when the current storage amount is 30% and the designated storage amount is 50%, the charge charge corresponding to the charge amount of 20% is displayed. In this case, the server 402 calculates based on the unit price information of the charge charge and the difference between the current storage amount and the designated storage amount, and transmits the calculation to the mobile terminal 401 together with the navigable range. In this case, the user can easily grasp the information on the waiting time and the charge as well as the navigable range.

Further, the mobile terminal 401 can accept the facility search, and may display the facility positions belonging to the desired category on the map on which the navigable range is superimposed. For example, if an amusement park is selected as the desired category and the amusement park around the current position of the vehicle is displayed, the navigable range display indicates how much the user should charge to reach which amusement park. It becomes easy to grasp, and the target storage rate can be easily determined.

Further, in the first embodiment, the server 402 is configured to determine the navigable range based on the virtual storage amount, but the function of the server 402 (each function of the server 402 in FIG. 4) is performed by the mobile terminal 401 or the in-vehicle device 403. It can also be configured to be prepared and executed.

FIG. 7 is a diagram showing a system configuration example for displaying the navigable range based on the virtual storage amount according to the second embodiment. In the second embodiment, the functions of the terminal 101 shown in FIG. 1 are added to the mobile terminal 401, the server 402, and the in-vehicle device 403 (see FIG. 4), and a charging device 704 is provided, and these devices communicate with each other. Do and execute.

In the second embodiment, the charging device 704 of the charging facility displays a map image on which the navigable range is superimposed, and the user confirms the navigable range displayed on the charging device 704 and charges the target storage rate. It is determined by the operation for the device 704.

The charging device 704 includes a transmission / reception unit 711, a display control unit 712, a storage amount designation IF 713, a display 714, and a power feeding unit 715. The transmission / reception unit 711 transmits the designated storage rate set by the user to the server 402, and receives the navigable range data from the server 402. The display control unit 712 performs display control processing for setting the virtual storage amount (designated storage amount) shown in FIG. 5 and displaying the navigable range on the display 714. The charge amount designation IF713 is composed of a charge amount designation determination button 503 (see FIG. 5). The power feeding unit 715 charges the battery of the vehicle 400.

In the second embodiment, assuming that the vehicle is located at the installation position of the charging device 704, the server 402 calculates the navigable range centering on the charging device 704 (vehicle). Therefore, in the second embodiment, the current position acquisition unit 433 (see FIG. 4) can be eliminated.

In the second embodiment, the user's personal identification information is registered in the charging device 704, the charging device 704 transmits the user's personal identification information and the vehicle identification information to the server 402, and the server 402 performs inquiry processing. Then, the charging completion notification when the charging by the power feeding unit 715 is completed can be notified from the charging device 704 to the mobile terminal 401 by e-mail or the like.

As a modification of the second embodiment described above, the server 402 may not be provided, and each functional unit of the server 402 may be provided in the charging device 704, and the system may be configured by the mobile terminal 401 and the charging device 704. In Example 2 described above, the same action and effect as in Example 1 can be obtained.

According to each of the above-described embodiments, by setting the virtual storage amount, it is possible to present the user with the navigable range that can be reached by the virtual storage amount. Since the virtual storage amount can be set in the state before charging the vehicle battery, the user can easily grasp the navigable range that can be reached according to the set virtual storage amount. In addition, the required actual storage amount (charge amount) can be set based on the displayed navigable range display. Then, the amount of charge that can reach the required destination can be easily obtained. In addition, even if a clear destination is not decided, the target storage amount for the vehicle battery can be clearly decided, and even if the destination is ambiguous, how much charge should be made can be appropriately determined. become.

In addition, each time the virtual storage amount is changed continuously or stepwise, different navigable ranges corresponding to the changed virtual storage amount can be presented to the user on the map screen, and when the charge amount is changed. The state of change in the navigable range can be presented to the user in an easy-to-understand manner.

It should be noted that each embodiment is not limited to this, and can be implemented without changing the purpose thereof. For example, the energy source for driving the power source of the mobile body is not limited to the electric power stored in the battery, and may be gasoline, hydrogen, natural gas, or the like stored in the storage tank. Even when supplying energy to a moving body using these as energy sources, by setting the virtual energy storage amount, it is possible to present to the user the navigable range that can be reached by the virtual energy storage amount.

The method for displaying the navigable range described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, flexible disk, CD-ROM, MO, or DVD, and is executed by being read from the recording medium by the computer. Further, this program may be a transmission medium that can be distributed via a network such as the Internet.
