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

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

  The terminal 101 includes 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 power storage amount of the battery that drives the power source of the vehicle by a user operation. The virtual power storage amount is a charge amount when the battery is charged in a state before actual charging (current) of the battery. For example, when the current storage amount (storage rate) is 30%, if 50% is input as the temporary storage amount, battery charging for 20% is actually performed later.

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

  Moreover, the acquisition part 103 can also acquire the prediction charging waiting time until it reaches | attains virtual storage amount in addition to the navigable range of the vehicle according to virtual storage amount. The expected charging waiting time is calculated by the server or the charging device that charges the battery, for example, based on 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 charging waiting time on the display unit 105 in conjunction with the virtual power storage amount.

  Furthermore, the terminal 101 includes a reception unit 106, a transmission unit 107, a reception unit 108, and a search unit 109. In addition, the terminal 101 may include a charging unit 110 that charges a vehicle battery.

  The accepting unit 106 accepts an operation for setting the virtual power storage amount as the target power storage amount when an image including a navigable range corresponding to the virtual power 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 determination button on the display unit 105. The transmission unit 107 transmits the target power storage amount to the external device 111 mounted on the vehicle when the target power storage amount is set. 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 vehicle battery.

  In addition, the receiving unit 108 receives the charge completion information transmitted by the external device 111 when the storage amount of the vehicle battery reaches the target storage amount. The receiving unit 108 can also receive vehicle current position information. The current position of the vehicle can be detected by, for example, a GPS by an in-vehicle device that is the external device 111. 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 so as to overlap the navigable range.

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

  As described above, as a system configuration for displaying the navigable range, a configuration including the terminal 101, the server, and the charging device of the charging facility can be considered. Further, if the terminal 101 calculates the server functions described above, 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 a function of the terminal 101, and may display a map image on which the navigable range of the vehicle is superimposed when charging is connected to the vehicle.

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

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

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

  The navigable range corresponding to the storage amount of the battery can be obtained, for example, by the technique disclosed in International Publication No. 2013/125019. For example, a plurality of points that can be reached from the current position with the amount of battery charge can be obtained using a predetermined energy consumption calculation formula, and the range that can be navigated can be shown on the map by combining these points. .

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

  As described above, it is possible to display the navigable range on the map by inputting the virtual power storage amount before the battery is actually charged. At this time, since the navigable range according to the virtual power storage amount can be displayed, for example, the virtual power storage amount for reaching the desired facility can be obtained. Thereafter, the user can travel to the desired facility and the navigable range by actually performing charging corresponding to the determined virtual power storage amount. In this way, even when a clear destination is not decided, the target power storage amount for the vehicle battery can be decided clearly, and even when the destination is ambiguous, it is possible to appropriately determine how much charging is required. You can do it.

  The virtual power storage amount can be input at an arbitrary location. For example, the virtual power storage amount is input immediately before the vehicle arrives at the charging facility and is charged, so that it is the current position of the vehicle. The navigable range based on the charging facility can be displayed.

The first embodiment is a configuration example in which the functions of the terminal 101 described in FIG. 1 are distributed and executed by a plurality of devices. The functions of the terminal 101 are executed by a mobile terminal 401 carried by the user, a server 402, and an in-vehicle device 403 such as a navigation device mounted on the vehicle, communicating with each other.

  The portable terminal 401 includes a transmission / reception unit 411, a display control unit 412, a storage amount designation IF 413, and a display 414. Moreover, although not shown, it has a power storage rate setting application for executing processing for setting a virtual power storage amount and displaying a map of a navigable range.

  The transmission / reception unit 411 communicates with the server 402, for example, transmits a specified power storage rate (the virtual power storage amount) specified by the user to the server 402 and receives navigable range data from the server 402. The display control unit 412 displays the above-described power storage amount and virtual power storage amount on the display 414 and displays the navigable range of the vehicle received from the server 402. The storage amount designation IF 413 has the function of the reception unit 106 described above, and includes a charge amount designation determination button or the like that determines the virtual storage amount (specified storage rate specified by the user) as the target storage amount.

  The server 402 includes a communication I / F 421, a navigable range estimation software 422 that functions as a navigable range estimation unit, a map database (DB) 423, and a communication I / F 424. The communication I / F 421 performs communication with the portable terminal 401, and transmits, for example, data on the navigable range calculated by the server 402 to the portable terminal 401.

  The navigable range estimation software 422 is an application that calculates the navigable range that can be reached from a current position with a predetermined charged amount (including when a virtual charged amount is input) by executing a program on a processor such as the CPU of the server 402. is there. The map DB 423 stores map data that is referred to when the navigable range is calculated by the navigable range estimation software 422. The communication I / F 424 performs communication with the in-vehicle device 403, transmits the specified storage rate from the server 402 to the in-vehicle device 403, and receives the current position of the vehicle and the current storage rate from the in-vehicle device 403.

(Regarding the designation of virtual power storage amount)
FIG. 5 is a diagram for explaining the designated state of the virtual power storage amount in the first embodiment. The display example which the display control part 412 of the portable terminal 401 displays on the display 414 is shown. FIG. 5A shows a state in which a navigable range based on the current power storage amount is displayed as a map. The portable 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 in-vehicle device 403 is output to the portable terminal 401 via the server 402. The mobile terminal 401 displays the current storage rate at the position of the slider 502 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 power storage rate of 30%. The position of the slider 502 can be changed continuously or stepwise (for example, in units of 10%) by a user operation. By sliding the slider 502 by this user operation, the virtual storage amount (specified storage rate) is increased. Be changed.

  For example, as shown in FIG. 5B, when the slider 502 is slid to a position of 40%, navigation corresponding to the virtual storage amount 40% at the slider 502 position is possible in the storage amount display area 501 of the display 414. A range D2 is displayed. This navigable range D <b> 2 is displayed by receiving navigable range data from the server 402 after transmitting the virtual storage amount 40% to 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 ranges D1 and D2, and the virtual storage amount at this time is designated as the charge amount. Setting is made with the OK button 503. The portable terminal 401 transmits the virtual storage amount (40%) when the user operates the determination button 503 for specifying the charge amount to the server 402 as the specified storage rate. The determination button 503 for specifying the charge amount corresponds to the function of the receiving unit 106 described in FIG.

  When setting the virtual power storage amount, the user searches for a desired destination (facility) and displays the destination (facility) of the search result on the display 414, so that the destination is within the navigation range D2. The slider 502 can be slid by a predetermined amount so that the ground (facility) is included. The destination (facility) search process is executed by the server 402 using the map DB 423, for example, a list of destination (facility) candidates by genre is transmitted to the mobile terminal 401, and the mobile terminal 401 selects the destination (facility). The server 402 performs search by selecting from the candidate list.

  Although FIG. 5 illustrates an example in which the power storage rate is increased with respect to the current power storage rate, the virtual power storage amount can be set lower than the current power storage rate. In this case, it is possible to display a navigable range (range narrower than the current navigable range D1) when the virtual power storage amount is lower than the current power storage rate without charging the battery at the current power storage rate. .

(Example of processing of Example 1)
Next, an example of a calculation process for the navigable range based on the virtual power storage amount according to the configuration example of the first embodiment will be described. FIG. 6 is a flowchart illustrating the processing contents for displaying the navigable range based on the virtual power 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 described in FIG. In the first embodiment, the server 402 calculates a reachable range with the power storage rate selected by the mobile terminal 401, and the user determines the power storage rate while viewing the image of the navigable range on the mobile terminal 401. This is a configuration example of notifying the vehicle-mounted device 403 of the completion of charging. In the example of FIG. 6, an example is described in which processing is started in a state where the vehicle 400 has reached a charging facility that can be charged by a battery.

  First, the in-vehicle device 403 determines whether the vehicle 400 has stopped at the charging facility by the current position acquisition unit 433 (step S601). The vehicle-mounted device 403 waits 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, the current position, and the storage rate acquisition unit of the vehicle 400 The storage ratio acquired by 431 is transmitted to the server 402 (step S602). Thereafter, the in-vehicle 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 start-up waiting state for the storage rate setting application in the initial state (step S604: No loop). For example, when the vehicle 400 reaches a charging facility where battery charging is possible, a user operation or the like. 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 in-vehicle device 403 (step S606), and receives the personal identification information from the portable terminal 401 (step S607). Then, the server 402 determines whether there is an association between the vehicle identification information and the personal identification information (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), it is set as standby in the example of FIG. 6, but since the service is not registered, the following service (navigable range based on virtual storage amount) The presenting service) may not be performed. 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 portable terminal 401 performs a setting process of the virtual power storage amount and a display process of a navigable range corresponding to the virtual power storage amount (steps S609 to S612). Moreover, the server 402 performs the calculation process of the navigable range corresponding to virtual storage amount after execution of step S608 (step S613 to step S615).

  The server 402 calculates a navigable range when the power storage rate is N% (current power storage rate) based on the current power storage rate transmitted from the in-vehicle device 403 by the navigable range estimation software 422 (step S614). The possible range data is transmitted to the portable terminal 401 (step S615). The portable terminal 401 displays the navigable range when the storage rate transmitted from the server 402 is N% on the map data (step S610). In this state, a navigable range D1 shown in FIG.

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

  Thereafter, when the user determines the virtual power storage amount and the charge amount designation button is operated on the mobile terminal 401 (step S611: determination), the mobile terminal 401 uses the determined virtual power storage amount (specified power storage rate) to the in-vehicle device. It transmits to 403 (step S612). The portable terminal 401 may transmit this designated power storage rate to the in-vehicle device 403 via the server 402.

  When receiving the specified power storage rate from the portable terminal 401 (step S616), the vehicle-mounted device 403 starts charging the battery with the charging facility and waits until the power storage rate reaches the specified power storage rate (step S617: No loop). If the storage rate reaches the specified storage rate (step S617: Yes), the charging is stopped and the fact that the specified storage rate has been reached is transmitted to the portable terminal 401 (step S618). The portable terminal 401 informs the user that the specified power storage rate has been reached by a display or the like (step S619), and ends the series of the above processes. The charging facility can also start charging in step S603, assuming battery charging to the stopped vehicle.

  Further, the navigable range estimation software 422 of the server 402, in the calculation of the navigable range in step S614, the basic data stored corresponding to the vehicle type included in the vehicle identification information or the unique ID identified by the vehicle ID. A highly navigable range can be calculated by using the basic data stored as the past driving history of the vehicle.

  In the above processing example, the server 402 calculates the navigable range every time the power storage rate parameter is changed. From the beginning, a plurality of navigable ranges in 10% steps are calculated, The navigable range data may be transmitted to the portable terminal 401. Thereby, when the power storage rate is changed by the portable 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 in 10% steps can be displayed by animation expression.

  Map data for displaying a map of the navigable range is stored in advance in the portable terminal 401, and the display control unit 412 can display the navigable range transmitted from the server 402 in a superimposed manner on the map data. In addition, a map image on which the navigable range is superimposed may be downloaded from the server 402 to the mobile terminal 401.

  In addition to this, an expected charging waiting time may be displayed in conjunction with the charged amount parameter. For example, when the current charged amount is 30% and the designated charged amount is 50%, 1 hour is displayed as an expected charging waiting time corresponding to a charged amount of 20%. In this case, the portable terminal 401 calculates the expected charging wait time for charging at the charging facility in accordance with the storage rate transmitted to the in-vehicle device 403. The charging facility may be configured to transfer the expected charging time to the portable terminal 401 via the in-vehicle device 403. In addition, the charge may be displayed in conjunction with the storage amount parameter. For example, when the current charged amount is 30% and the designated charged amount is 50%, a charge charge corresponding to a charged amount of 20% is displayed. In this case, the server 402 calculates based on the unit price information of the charging fee and the difference between the current charged amount and the specified charged amount, and transmits it to the portable terminal 401 together with the navigable range. In this case, the user can easily grasp the waiting time and fee information together with the navigable range.

  Moreover, the portable terminal 401 can accept facility searches, and may display facility locations belonging to a desired category on a map on which a navigable range is superimposed. For example, if an amusement park is selected as the desired category and an amusement park around the current position of the vehicle is displayed, the display of the navigable range indicates how much the user can charge to which amusement park by charging. It becomes possible to easily grasp, and a target power storage rate can be easily determined.

  In the first embodiment, the server 402 obtains the navigable range based on the virtual power storage amount. However, the function of the server 402 (each function of the server 402 in FIG. 4) is determined by the mobile terminal 401 or the in-vehicle device 403. It can also be set as the structure which prepares and performs.

And execute.

  In the second embodiment, the charging device 704 of the charging facility displays a map image in 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. This is determined by an operation on 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 navigable range data from the server 402. The display control unit 712 performs display control processing for displaying the virtual storage amount (specified storage amount) setting and the navigable range shown in FIG. 5 on the display 714. The storage amount designation IF 713 includes 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 with the charging device 704 (vehicle) as the center. For this reason, in the second embodiment, the current position acquisition unit 433 (see FIG. 4) can be omitted.

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

  As a modification of the second embodiment described above, the server 402 is not provided, and each functional unit of the server 402 is provided in the charging device 704, and the system can be configured by the portable terminal 401 and the charging device 704. In the second embodiment described above, the same effects as those of the first embodiment can be obtained.

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

  In addition, every time the virtual power storage amount is changed continuously or stepwise, different navigable ranges corresponding to the changed virtual power storage amount can be presented to the user on the map screen, and 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.

  In addition, each embodiment is not limited to this, It can implement in the range which does not change the meaning. For example, the energy source that drives the power source of the moving 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 energy is supplied to a moving body using these as energy sources, a navigable range that can be reached with the virtual energy storage amount can be presented to the user by setting the virtual energy storage amount.

  The method for displaying the navigable range described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation.
