[0039] The operation of the information processing system 1 will be described with reference to FIG. 5 and FIGS. 6A and 6B.

[0040] FIG. 5 is a sequence diagram for explaining the operation procedure of the information processing system 1 in this embodiment. FIG. 5 shows the procedure for the cooperation operation of the server device 10, the vehicle 12, and the terminal device 13. Steps related to various information processing of the server device 10, the vehicle 12, and the terminal device 13 in FIG. 5 are executed by the respective control units 23, 33, and 43. Furthermore, steps related to the transmission and reception of various information by the server device 10, the vehicle 12, and the terminal device 13 are executed by the respective control units 23, 33, and 43 transmitting and receiving information to each other via the communication units 21, 31, and 41, respectively. In the server device 10, the vehicle 12, and the terminal device 13, the control units 23, 33, and 43 appropriately store the information to be transmitted and received in the storage units 22, 32, and 42, respectively. Furthermore, the control units 23, 33, and 43 accept input of various information through the input units 25, 35, and 45, respectively, and output various information through the output units 26, 36, and 46, respectively.

[0041] In step S500, the vehicle 12 sends location information and vehicle information to the server device 10. The vehicle information includes, for example, vehicle identification information, vehicle model, type, specifications, etc. The vehicle information may include information about the owner or driver. Next, in step S502, the server device 10 sends the location information and vehicle information of the vehicle 12 to the terminal device 13. Then, the terminal device 13 sends a utilization request for the vehicle 12 to the server device 10. The utilization request is generated by the user operating the terminal device 13, and is sent to the server device 10. The utilization request includes information identifying the vehicle 12 that the user wishes to utilize, the boarding location, the boarding time, and other information.

[0042] In steps S500 to S504, for example, the user of the terminal device 13 accesses a portal site for members of a car sharing service or the like provided by the server device 10 using the terminal device 13. For example, the portal site displays the vehicle type, location, and the like of one or more available vehicles 12. The user selects the vehicle 12 that he / she wishes to use and inputs the boarding point, boarding time, his / her member ID, and the like into the terminal device 13. For example, as shown in FIG. 6A, the terminal device 13 displays a map 6 including the position 60 of the vehicle 12 and the current location 63 of the terminal device 13. The user, for example, taps the position 60 of the vehicle 12 and the desired boarding point 62 on the map 6 to input the selection of the vehicle 12 and the boarding point 62. The user may also input the designation of a boundary 64 of a reference range for displaying an image captured by the vehicle 12 by a slide operation or the like on the map 6. The reference range is a range of any distance from the boarding point 62. If the boundary 64 of the reference range is not specified, an arbitrarily set initial value (for example, several hundred meters) may be set as the reference range. The terminal device 13 generates a usage request based on the information specifying the selected vehicle 12 and the input information, and sends the usage request to the server device 10. The usage request includes information for identifying the terminal device 13.

[0043] In step S506, the server device 10 sends a usage confirmation request to the vehicle 12 specified in the usage request. The usage confirmation request includes information included in the usage request. The vehicle 12 displays information such as the boarding point and boarding time to the driver. The driver inputs the usage confirmation into the vehicle 12. The usage confirmation includes information indicating whether or not the usage request is accepted. For example, the driver inputs the usage confirmation by tapping a button indicating acceptance of the usage request. In step S508, the vehicle 12 sends the usage confirmation to the server device. Upon receiving the usage confirmation, the server device 10 executes steps S510 and S512. Note that, in the case where one or more of the parts of the vehicle 12 shown in FIG. 3 are configured as a terminal device having an information processing function and the terminal device is carried by the driver, steps S506 and S508 may be executed by the terminal device.

[0044] In step S510, the server device 10 sends usage information to the terminal device 13. The usage information indicates that the usage request has been accepted. The terminal device 13 displays the usage information to the user. When the user confirms that the usage request has been accepted, the user carries the terminal device 13 and moves to the boarding point.

[0045] In step S512, the server device 10 transmits a movement start instruction to the vehicle 12. Upon receiving the movement start instruction, the vehicle 12 starts moving from the current position toward the boarding point.

[0046] Steps S514 to S522 are executed at any period (for example, at a period of several tens of milliseconds to several seconds).

[0047] In step S514, the vehicle 12 transmits the captured image and the position information to the server device 10. The captured image is an image of the surroundings of the vehicle 12, and is obtained by capturing an image of the scenery or subject in front of, to the side of, or behind the vehicle 12 in the traveling direction. The captured image may be a moving image captured at an arbitrary frame rate (e.g., 30 FPS). Here, the cycles of capturing images, obtaining position information, and transmitting the captured images and position information may be different.

[0048] Upon receiving the usage information, in step S516, the terminal device 13 sends the location information to the server device 10. Here, if the location of the vehicle 12 and the location of the terminal device 13 are both located at the boarding point, the server device 10 cancels the subsequent steps.

[0049] In step S518, the server device 10 determines the captured image to be sent. The server device 10 determines the captured image to be sent based on the position information sent from the vehicle 12 together with the captured image. The position information sent from the vehicle 12 together with the captured image generally corresponds to the location where the captured image was captured. Here, the server device 10 determines the captured image sent together with the position information as the captured image to be sent, on condition that the location of the vehicle 12 indicated by the position information is within a reference range from the boarding location, for example. Alternatively, when the position information sent from the terminal device 13 and the position information sent from the vehicle 12 match, the server device 10 may determine the captured image sent together with the position information as the captured image to be sent.

[0050] In step S520, the server device 10 transmits the determined captured image and the location information transmitted from the vehicle 12 together with the captured image to the terminal device 13. At this time, the server device 10 may transmit the captured image etc. on the condition that the location of the terminal device 13 is within a reference range from the boarding point.

[0051] In step S522, the terminal device 13 outputs the captured image and the position information sent from the server device 10. For example, as shown in FIG. 6B, the terminal device 13 displays a map 6 including a position 60 of the vehicle 12, a current position 63 of the terminal device 13, and a boarding point 62. A boundary 64 of a reference range may be displayed on the map 6. Here, since the position 60 of the vehicle 12 is within the reference range, the terminal device 13 displays a captured image 61. The captured image 61 is, for example, a captured image of a landscape in the traveling direction of the vehicle 12. The captured image 61 is also a moving image. The captured image 61 may be displayed superimposed on the map 6 as shown in FIG. 6B, or may be displayed in a portion of the display other than the map 6.

[0052] According to this embodiment, when a user moves to a boarding point, the user can view captured images of the surroundings of the vehicle 12 heading to the boarding point on the terminal device 13. Even if the boarding point is an unknown point, the user can specify the boarding point more easily than when specifying the boarding point on a map, and can efficiently meet up with the vehicle 12.

[0053] In addition, since displaying a captured image of a location more than a certain distance away from the boarding location has a relatively low contribution to identifying the boarding location, unnecessary processing and information communication can be omitted by displaying only captured images within a reference range. Furthermore, since comparing the scenery of a location more than a certain distance away from the boarding location with the captured image when the user moves to the boarding location has a relatively low contribution to identifying the boarding location, by making the terminal device 13 located within the reference range a condition for transmitting the captured image, the user can more easily compare the captured image with the surrounding scenery. Therefore, it is possible to identify the boarding location more reliably.

[0054] Alternatively, when the user moves to the boarding point, the user moves through a point where the vehicle 12 has passed, that is, when the position information acquired by the server device 10 from the vehicle 12 matches the position information of the terminal device 13, the captured image captured at that position is sent to the terminal device 13 and displayed. This allows the user to more reliably identify the boarding point by comparing the captured image with the surrounding scenery. Furthermore, the terminal device 13 may display the trajectory of the position of the vehicle 12, and a captured image of a point selected by the user on the trajectory may be displayed. For example, the user may select an arbitrary point on the trajectory of the vehicle 12 on the map 6 by a tap operation or the like, and the server device 10 may send a captured image of the selected point to the terminal device 13 based on the selection. This improves the user's convenience.

[0055] In the above embodiment, the server device 10 selected the captured image to be sent to the terminal device 13 based on the position information from the vehicle 12. However, the server device 10 may send information on the reference range to the vehicle 12 together with an instruction to start moving, and the vehicle 12 may determine whether to capture images or to stop sending the captured images based on its own current position. That is, when the vehicle 12's current position is located within the reference range, the vehicle 12 captures images and sends the captured images to the server device 10. Alternatively, the vehicle 12 captures images periodically, and when the vehicle's current position is located within the reference range, sends the captured images to the server device 10. In this way, when the server device 10 manages multiple vehicles 12, it is possible to avoid concentration of processing load on the server device 10.

[0056] In the above-described embodiment, the processing and control programs that stipulate the operation of the vehicle 12 and the terminal device 13 may be stored in the memory unit 22 of the server device 10 or in the memory unit of another server device and downloaded to each device via the network 11, or may be stored in a non-transitory recording and storage medium that is readable by each device and read from the medium by each device.

[0057] In the above, the embodiment has been described based on the drawings and examples, but it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present disclosure. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically inconsistent, and multiple means, steps, etc. can be combined into one or divided into one.
