5[6 actions of parts of the rental System

Next, operations of each part of the rental system 1 will be described.

First, operations of each part of the rental system 1 related to the uploaded information will be described.

Fig. 6 is a flowchart showing the operation of the rental system 1. In fig. 6, a flowchart FA shows the operation of the 1 st vehicle 5, and a flowchart FB shows the operation of the management server 7.

As shown in the flowchart FA, the 1 st communication control unit 501 determines whether or not a trigger for transmitting the upload information has occurred (step SA 1). Examples of the trigger include a predetermined time (for example, 10 minutes) elapsed since the last transmission of the upload information, ignition on of the 1 st vehicle 5, ignition off of the 1 st vehicle 5, and the like.

When determining that the trigger for transmitting the upload information has occurred, the 1 st communication control unit 501 (step SA1:

yes), upload information is generated (step SA 2).

5 in step SA2, the 1 st communication control unit 501 obtains the combination of the battery ID and the battery status information received by the 3 rd communication device 53 from the 3 rd communication device 53. The 1 st communication control unit 501 obtains the 1 st position information from the 1 st position detection device 55. Further, the 1 st communication control unit 501 obtains the lender ID from the memory 510. Further, the 1 st communication control unit 501 acquires the 2 nd battery information indicating the charge amount of the in-vehicle battery 56. The 1 st communication control unit 501 generates upload information including the acquired information.

The lender ID is stored in the memory 510 in advance at the time when the 2 nd communication device 52 and the lender terminal 6 establish a communication connection.

For example, when the in-vehicle battery 56 and the 3 rd communication device 53 are capable of communication and the 3 rd communication device 53 receives the 2 nd battery information from the in-vehicle battery 56, the 1 st communication control unit 501 obtains the 2 nd battery information from the 3 rd communication device 53. For example, when the in-vehicle battery 56 and the charging station controller 543 are communicable and the charging station controller 543 receives the 2 nd battery information from the in-vehicle battery 56, the 1 st communication controller 501 obtains the 2 nd battery information from the charging station controller 543.

Returning to the description of the flowchart FA, the 1 st communication control unit 501 transmits the generated upload information to the management server 7 (step SA 3).

As shown in the flowchart FB, the server receiving unit 701 receives the upload information from the 1 st vehicle 5 (step SB 1).

Next, the server reception unit 701 stores the upload information received in step SB1 in the upload information management DB714 (step SB 2).

In addition, in step SB2, when there is upload information having the same lender ID as the lender ID included in the upload information received in step SB1 in the upload information management DB714, the server reception unit 701 updates the upload information having the same lender ID to the upload information received in step SB 1.

Next, the operation of the rental system 1 related to the search of the power supply unit 2 for making a loan will be described.

Fig. 7 is a flowchart showing the operation of the rental system 1. In fig. 7, a flowchart FC shows the operation of the management server 7, and a flowchart FD shows the operation of the in-vehicle apparatus 80.

As shown in the flowchart FD, the 4 th communication control unit 801 determines whether or not to search for the lent power supply group 2 (step SD 1). For example, when the 1 st reception unit 803 receives a search instruction for the power supply unit 2 via the touch panel 830, the 4 th communication control unit 801 determines affirmative in step SD 1.

When it is determined that the search of the power supply unit 2 is performed (yes in step SD 1), the 4 th communication control unit 801 generates search request information (step SD 2).

In step SD2, the 4 th communication control unit 801 acquires the 2 nd position information from the 2 nd position detection device 82. Then, the 4 th communication control unit 801 generates search request information including the acquired 2 nd position information. Here, when the 1 st reception unit 803 receives the input of the destination from the lender 4, the 4 th communication control unit 801 includes the generated search request information with the information of the destination received by the 1 st reception unit 803.

Next, the 4 th communication control unit 801 transmits the search request information to the management server 7 (step SD 3).

As shown in the flowchart C, the server receiving unit 701 receives search request information (step SC 1).

Next, the generating unit 703 acquires an image of the map in the reference predetermined range from the map data 715 based on the search request information received in step SC1 (step SC 2). The reference predetermined range is a predetermined range (for example, a range of 10km radius around the reference) with reference to the current position indicated by the 2 nd position information of the search request information. The size of the range is predetermined.

Next, the generating unit 703 determines whether or not the uploaded information including the 1 st position information indicating the position within the reference predetermined range is stored in the uploaded information management DB714 (step SC 3).

When it is determined that the uploaded information management DB714 does not store the uploaded information including the 1 st position information indicating the position within the reference predetermined range (step SC3: no), the generating unit 703 performs the processing of step SC 11.

On the other hand, when it is determined that the uploaded information management DB714 stores the uploaded information including the 1 st position information indicating the position within the reference predetermined range (yes in step SC 3), the generating unit 703 performs the processing of step SC4 with respect to the uploaded information including the 1 st position information indicating the position within the reference predetermined range. That is, the generation unit 703 determines whether or not there is upload information including battery state information for which a predetermined condition is satisfied, among the upload information to be targeted (step SC 4).

In the present embodiment, the battery state information in which the predetermined condition is satisfied is battery state information in which the 1 st predetermined condition or the 2 nd predetermined condition is satisfied.

The battery state information indicating that the 1 st predetermined condition is satisfied is battery state information indicating that the charge amount of the power supply unit 2 is equal to or more than a predetermined amount (for example, 50% of the charge amount at the time of full charge).

The battery state information that the 2 nd predetermined condition is satisfied is the battery state information of the power supply unit 2 that is receiving power supply from the in-vehicle battery 56 that is charged by a predetermined amount or more, and is the battery state information indicating that the power supply unit 2 is being charged.

The generation unit 703 determines whether or not the battery state information satisfies a predetermined condition as follows.

When the battery state information to be determined indicates a charge amount equal to or greater than a predetermined amount, the generation unit 703 determines that the battery state information to be determined is battery state information for which the 1 st predetermined condition is satisfied.

The generation unit 703 determines that the battery state information to be determined is battery state information for which the 2 nd predetermined condition is satisfied, when the battery state information to be determined indicates charging and the 2 nd battery information including the upload information of the battery state information to be determined indicates a charge amount equal to or greater than a predetermined amount.

When determining that there is no uploaded information including battery state information for which a predetermined condition is satisfied (step SC4: no), the generating unit 703 performs the processing of step SC 11.

On the other hand, when the generation unit 703 determines that there is the upload information including the battery state information for which the predetermined condition is satisfied (yes in step SC 4), the search unit 704 determines whether or not the information of the destination is included in the search request information received in step SC1 (step SC 5).

When the search unit 704 determines that the destination information is not included (step SC5: no), the generation unit 703 generates a 1 st map image TG1 (step SC 6).

The 1 st map image TG1 is a map image in which battery state information that satisfies a predetermined condition is displayed at a position on a map of a reference predetermined range corresponding to the current position of the 1 st vehicle 5.

Fig. 8 is a diagram showing an example of the 1 st map image TG1.

The map shown in the 1 st map image TG1 is a map of a reference predetermined range. In the 1 st map image TG1, battery state information that a predetermined condition is satisfied is displayed as an icon. Hereinafter, this icon will be referred to as the 1 st icon, and a reference numeral of "IC1" will be given thereto. Icon 1 IC1 is included in icon 2 IC2. The 2 nd icon IC2 is an icon including 1 or more 1 st icons IC1, and the 2 nd icon IC2 is generated for each piece of uploaded information. The 1 st icon IC1 is an icon indicating that the battery is being charged when the corresponding battery state information indicates that the battery is being charged, and is an icon indicating that the battery is being charged when the corresponding battery state information does not indicate that the battery is being charged.

In fig. 8, a 1 st map image TG1 is shown with 2 nd icons IC2-1, IC2-2 displayed. Icon 2 IC2-1 includes icons 1 IC1-1, IC1-2, IC1-3. The 1 st icons IC1-2, IC1-3 each represent the charge amount of the power supply unit 2. Icon 2 IC2-2 includes icons 1, 1-4, 1-5, 1-6, 1-7, and 1-8. The 1 st icons IC1-4, IC1-5, IC1-6 each represent the charge amount of the power supply unit 2. The 1 st icon IC1-7, IC1-8 each represent charging.

The generation unit 703 generates a 1 st map image TG1 as follows, using, as a processing target, upload information including 1 st position information indicating a position within a reference predetermined range and including battery state information for which a predetermined condition is satisfied.

The generating unit 703 generates the 1 st icon IC1 for each battery state information for which a predetermined condition is satisfied among the battery state information included in the upload information of the processing target. Next, the generating unit 703 generates a 2 nd icon IC2 in which the 1 st icon IC1 is arranged. The generating unit 703 arranges the generated 2 nd icon IC2 at a position on the map corresponding to the current position shown by the 1 st position information included in the upload information of the processing object in the image of the map acquired in step SC 2. By disposing the 2 nd icon IC2, the 1 st icon IC1 is disposed at a position on the corresponding map. The generating unit 703 generates and disposes the 2 nd icon IC2 with respect to the upload information of all the processing targets, thereby generating the 1 st map image TG1.

Returning to the explanation of fig. 7, the server transmitting unit 702 transmits the 1 st map image data, which is the image data of the 1 st map image TG1 generated in step SC6, to the 2 nd vehicle 8 (step SC 7).

Returning to the explanation of step SC5, when it is determined that the destination information is included (step SC5: yes), the search unit 704 performs route search (step SC 8). The route retrieved in step SC8 is a route from the current position indicated by the 2 nd position information of the retrieval request information received in step SC1 to the destination indicated by the information of the destination containing the retrieval request information.

Next, the generating unit 703 generates a 2 nd map image TG2 (step SC 9).

The 2 nd map image TG2 is a map image that displays an image of the route searched for in step SC8 in addition to the display content of the 1 st map image.

Fig. 9 is a diagram showing an example of the map image TG2 of fig. 2.

The 2 nd map image TG2 shown in fig. 9 exemplifies the following map image: in addition to the display content of the 1 st map image TG1 shown in fig. 8, a route image RG as an image of a route is displayed.

The generating unit 703 generates a route image RG indicating the route searched by the searching unit 704. Then, the generating unit 703 arranges the generated route image RG and the 2 nd icon IC2 on the map image acquired in step SC, and generates a 2 nd map image TG2.

Returning to the description of fig. 7, the server transmitting unit 702 transmits the 2 nd map image data, which is the image data of the 2 nd map image generated in step SC9, to the 2 nd vehicle 8 (step SC 10).

When the determinations at steps SC3 and SC4 are negative, the generation unit 703 generates the 3 rd map image (step SC 11). The 3 rd map image is a map image representing a map of a reference predetermined range, and does not include the 2 nd icon IC2 and the route image RG.

When the generation unit 703 generates the 3 rd map image, the server transmission unit 702 transmits 3 rd map image data, which is image data of the 3 rd map image, to the 2 nd vehicle 8 (step SC 12).

As shown in the flowchart FD, the 4 th communication control section 801 receives any map image data among the 1 st map image data, the 2 nd map image data, and the 3 rd map image data (step SD 4).

The 1 st display control unit 802 causes the touch panel 830 to display a map image corresponding to the image data received in step SD4 (step SD 5). That is, when the 4 th communication control unit 801 receives the 1 st map image data, the 1 st display control unit 802 causes the touch panel 830 to display the 1 st map image. When the 4 th communication control unit 801 receives the 2 nd map image data, the 1 st display control unit 802 causes the touch panel 830 to display the 2 nd map image. When the 4 th communication control unit 801 receives the 3 rd map image data, the 1 st display control unit 802 causes the touch panel 830 to display the 3 rd map image. In addition, in the display of the 1 st map image TG1 and the 2 nd map image TG2, the 1 st display control section 802 causes the 1 st icon IC1 to be displayed so as to be selectable by a touch operation.

Next, the operation of the rental system 1 related to the request for borrowing of the power supply set 2 will be described.

As shown in the flowchart FE, the 1 st reception unit 803 receives selection of the 1 st icon IC1 from the 1 st map image TG1 or the 2 nd map image TG2 displayed on the touch panel 830 (step SE 1).

Next, the 4 th communication control unit 801 transmits borrowing request information requesting borrowing of the power supply group 2 to the management server 7 (step SE 2). The borrowing request information includes a lender ID corresponding to the selected 1 st icon IC1, a battery ID corresponding to the selected 1 st icon IC1, and a lender ID stored in the memory 810.

In the map image data 1 and the map image data 2, the battery IDs of the corresponding power supply groups 2 are associated with each other for each of the icon 1 IC 1. In the map image data 1 and the map image data 2, the lender ID of the lender 3 of the corresponding power supply group 2 is described in association with each of the icon 1 IC 1.

As shown in the flowchart FF, the server receiving unit 701 receives the borrowing request information from the in-vehicle apparatus 80 (step SF 1).

Next, the server transmitting unit 702 transmits the borrowing request information and the lending destination information received in step SF1 to the 1 st vehicle 5 and the 1 st vehicle 5 based on the lender ID and the lender ID included in the borrowing request information received in step SF1 (step SF 2).

Step SF2 will be described in detail.

The server transmitting unit 702 acquires communication information corresponding to the lender ID included in the borrowing request information from the lender management DB 712. Next, the server transmitting unit 702 acquires the lender information corresponding to the lender ID included in the borrowing request information from the lender management DB 713.
