DESCRIPTION OF THE EMBODIMENTS

A system according to a first aspect of the present disclosure includes a user terminal, a server device, and an in-vehicle device. The user terminal is a terminal owned by a user who uses the system. The in-vehicle device is a device mounted on a vehicle that the user who uses the system is going to get into. Additionally, the server device is a device capable of communicating with the user terminal and the in-vehicle device through a network.


Individual setting information of the user who is going to get into the vehicle is stored in the user terminal and the server device. The individual setting information is information for performing various settings in pieces of equipment provided in the vehicle. That is, the individual setting information is information for customizing, when the user has gotten into the vehicle, the various settings in the pieces of equipment provided in the vehicle to the settings corresponding to the user having gotten into the vehicle.


Here, first information which is a part of the individual setting information is stored in the user terminal. Additionally, second information which is information other than the first information in the individual setting information is stored in the server device. When the user gets into the vehicle, the individual setting information is transmitted from both of the user terminal and the server device. That is, the first information is transmitted to the in-vehicle device from the user terminal owned by the user. Additionally, the second information is transmitted to the in-vehicle device from the server device. At this time, the first information is transmitted to the in-vehicle device from the user terminal through short-range wireless communication. That is, the first information is transmitted directly to the in-vehicle device from the user terminal. Additionally, the second Information is transmitted to the in-vehicle device from the server device through a network. Then, the in-vehicle device transmits the first information received from the user terminal and the second information received from the server device to an equipment control device that controls the pieces of equipment (pieces of equipment to be customized based on the first information and the second information) provided in the vehicle. When the equipment control device receives the first information or the second information, various settings in the pieces of equipment to be customized are customized to the settings corresponding to the user who has gotten into the vehicle, based on the received information.


Here, as described above, the first information is transmitted directly to the in-vehicle device from the user terminal by short-range wireless communication. Accordingly, the first information can be transmitted to the in-vehicle device more quickly as compared with a case where like the second information, the first information is transmitted to the in-vehicle device from the server device through the network. Therefore, in the vehicle, the customization of the pieces of equipment to be customized based on the first information can be completed at an earlier stage.


On the other hand, if not only the first information but also the second information are transmitted to the in-vehicle device from the user terminal by short-range wireless communication, not only the first information but also the second information need to be stored in the user terminal. In this case, the user terminal requires a very large storage capacity to store the individual setting information. Meanwhile, the individual setting information to be transmitted from the user terminal to the in-vehicle device is only the first information, and the second information is transmitted from the management server to the in-vehicle device, thereby making it possible to reduce the storage capacity of the user terminal required to store the individual setting information.


Hereinafter, specific embodiments of the present disclosure will be described with reference to the drawings. Dimensions, materials, and shapes of components described in the embodiments, relative arrangements thereof, and the like are not intended to limit the technical scope of the present disclosure only thereto unless otherwise noted.


First Embodiment

On the other hand, like vehicles for ride sharing or rental vehicles, one vehicle may be used by a plurality of users in some cases. In such a case, it is desirable to customize various settings in pieces of equipment for each user (user as a driver) who uses the vehicle. Here, an embodiment will be described in which a system, an in-vehicle device, and an information processing method according to the present disclosure are applied to a system for customizing, for each user, various settings in pieces of equipment mounted on such a vehicle used by a plurality of users.

However, some or all of the functions of the in-vehicle device 200 may be implemented by hardware circuits such as an ASIC and an FPGA. Note that, the in-vehicle device 200 does not necessarily have to be achieved by a single physical configuration and nay be formed by a plurality of computers operating in coordination.


Individual Setting Information

Here, a specific example of the individual setting information for customizing the vehicle 20 will be described with reference to FIG. 3. FIG. 3 is a diagram illustrating specific examples of pieces of equipment to be customized based on the individual setting information and setting items.

The individual setting information of each user includes set values for each user with respect to the respective setting items of the pieces of equipment to be customized, as illustrated in FIG. 3. In the vehicle 20, the setting items of the pieces of equipment are controlled by the equipment ECU 400 based on the individual setting information of a specific user who has gotten into the vehicle 20. Thus, various settings in the pieces of equipment are customized to reflect the set values included in the individual setting information of the specific user.


In the information management system 1, the individual setting information of each user is divided into the first information and the second information, as described above. That is, among the plurality of setting items in the plurality pieces of equipment as illustrated in FIG. 3, the set values of some setting items are regarded as the first information, and the set values of the other setting items are regarded as the second information. At this time, the setting items included in the first information and the setting items included in the second information are predefined. That is, in the individual setting information, the information treated as the first information and the information treated as the second information are predefined. Specifically, the information (set values) about the setting items, the customization of which is desired to be completed at a relatively earlier stage when the user has gotten into the vehicle 20, is defined as the first information. However, in the individual setting information of one user, the first information and the second information are defined so that the total data capacity of the second information is larger than the total data capacity of the first information.


In the information management system 1, the first information of each user is stored in the user terminal 100 owned by each user. The second information of each user is stored in the management server 300. In this way, in the information management system 1, the in-vehicle device 200 receives the first information stored in one or a plurality of the user terminals 100 existing in a predetermined range from the vehicle 20, directly therefrom by short-range wireless communication. Here, the predetermined range is a range in which short-range wireless communication can be performed between the in-vehicle device 200 and the user terminal 100. Note that in FIG. 1, a range enclosed by a dashed line indicates the predetermined range. That is, the in-vehicle device 200 receives the first information not only from the user terminal 100 owned by a user who is going to get into the vehicle 20 but also from the user terminal 100 owned by each of the other users existing around the vehicle 20. Additionally, the in-vehicle device 200 receives the first information from the user terminal 100 owned by the user who actually gets into the vehicle 20, at the point in time before the user gets into the vehicle 20. Furthermore, the in-vehicle device 200 stores the first information received from one or the plurality of user terminals 100 in an individual setting information database which will be described later.


Furthermore, the in-vehicle device 200 performs an authentication process of specifying a specific user who is a user having gotten into the vehicle 20. Then, the in-vehicle device 200 selects the first information corresponding to the specific user specified by the authentication process out of the first information stored in the individual setting information database, and transmits the selected first information to the equipment ECU 400. Hereby, the pieces of equipment to be customized are customized by the equipment ECU 400 based on the first information. Additionally, the in-vehicle device 200 receives the second information corresponding to the specific user from the management server 300, and transmits the received second information to the equipment ECU 400. Hereby, the pieces of equipment to be customized are customized by the equipment ECU 400 based on the second information.

Note that in FIG. 5, two user terminals 100 existing in the predetermined range from the vehicle 20 are represented by a user terminal 100a and a user terminal 100b.


In the present embodiment, the in-vehicle device 200 receives the first information, the user ID, and the PIN code from each of the user terminals 100 (100a and 100b) existing in the predetermined range from the vehicle 20, by short-range wireless communication (S11). Then, the in-vehicle device 200 stores, in the individual setting information DB 260, the first information, the user ID, and the PIN code that are received from each of the user terminals 100 (S12). At the point in time when the process of S12 is performed, the user to be specified as a specific user has not gotten into the vehicle 20 yet. Additionally, the first information of the other users who do not actually get into the vehicle 20 is also stored in the individual setting information DB 260, the other users existing around the vehicle 20.


Then, when the specific user gets into the vehicle 20, the PIN code of the user terminal 100 owned by the specific user is input to the input/output I/F 207 of the in-vehicle device 200 by the specific user (S13). Note that, at this time, the PIN code may be displayed on the input/output I/F of the user terminal 100 owned by the specific user. In this case, the specific user may input the PIN code to the input/output I/F 207 of the in-vehicle device 200 with reference to the PIN code displayed on the user terminal 100 owned by the specific user. Additionally, the specific user may cause the input/output I/F 207 of the in-vehicle device 200 to read the PIN code displayed on the user terminal 100 owned by the specific user.


When the PIN code is input to the input/output I/F 207 by the specific user, the in-vehicle device 200 performs the authentication process of specifying the specific user (S14). The authentication process is performed based on the PIN code input by the specific user. Specifically, among users whose first information is stored in the individual setting information DB 260, a user associated with the sane PIN code as the PIN code input to the input/output I/F 207 is determined as the specific user. Then, in the in-vehicle device 200, the first information of the specific user specified by the authentication process is selected out of the first information stored in the individual setting information DB 260 (S15). That is, the first information associated with the same PIN code as the PIN code input to the input/output I/F 207 is selected as the first information of the specific user. Furthermore, the in-vehicle device 200 transmits the selected first information (the first information of the specific user) to the equipment ECU 400 (S16). Note that, in the in-vehicle device 200, when the specific user is specified by the authentication process, the information (the first information, the user IDs, and the PIN codes) corresponding to the users other than the specific user that is temporarily stored in the individual setting information DB 260 is delated from the individual setting information DB 260. The process of deleting the information corresponding to the users other than the specific user from the individual setting information DB 260 in the in-vehicle device 200 is performed by the controller 210. This can prevent unnecessary information from remaining stored in the individual setting information DB 260.


When the specific user is specified by the authentication process, the in-vehicle device 200 transmits the user ID (the user ID associated with the same PIN code as the PIN code input to the input/output I/F 207) of the specific user stored in the individual setting information DB 260 from the in-vehicle device 200 to the management server 300 through the network N1 (S17). In the management server 300, when the user ID of the specific user is received, the second information corresponding to the user ID of the specific user is selected out of the second information stored in the second information DB 330 (S18). That is, the second information associated with the same user ID with the user ID received from the in-vehicle device 200 is selected as the second information of the specific user. Furthermore, the management server 300 transmits the selected second information (the second information of the specific user) to the in-vehicle device 200 through the network N1 (S19). Then, the in-vehicle device 200 transmits, to the equipment ECU 400, the second information of the specific user received from the management server 300 (S20).


Effect by This System

As described above, in the information management system 1, the individual setting information of each user used for customizing the vehicle 20 is divided into the first information and the second information. The first information is stored in the user terminal 100, the first information serving as information about the setting items, the customization of which is desired to be completed at a relatively earlier stage when the user has gotten into the vehicle 20. In this way, when the user gets into the vehicle 20, the first information is transmitted directly to the in-vehicle device 200 from the user terminal 100 by short-range wireless communication. On the other hand, the second information is transmitted to the in-vehicle device 200 from the management server 300 through the network N1.


Therefore, when the user gets into the vehicle 20, the first information is transmitted to the in-vehicle device 200 more quickly than the second information. Accordingly, the first information can be transmitted to the in-vehicle device 200 more quickly as compared with a case where like the second information, the first information is transmitted to the in-vehicle device 200 from the management server 300 through the network N1. Therefore, in the vehicle 20, the customization of the pieces of equipment to be customized based on the first information can be completed at an earlier stage. That is, according to the information management system 1, the customization of the pieces of equipment to be customized based on a part (first information) of the individual setting information can be completed at an earlier stage as compared with a case where all of the individual setting information including the first information and the second information is transmitted to the in-vehicle device 200 from the management server 300.


On the other hand, if not only the first information but also the second information are transmitted to the in-vehicle device 200 from the user terminal 100 by short-range wireless communication, not only the first information but also the second information need to be stored in the user terminal. In this case, the user terminal 100 requires a very large storage capacity to store the individual setting information. Meanwhile, in the information management system 1, the individual setting information to be transmitted from the user terminal 100 to the in-vehicle device 200 is only the first information, and the second information is transmitted from the management server 300 to the in-vehicle device 200, thereby making it possible to reduce the storage capacity of the user terminal 100 required to store the individual setting information. Additionally, as described above, in the individual setting information of one user, the total data capacity of the second information is larger than the total data capacity of the first information. Thus, when the total data capacity of the first, information is reduced, the storage capacity of the user terminal 100 required to store the first information can be further reduced.


Furthermore, in the information management system 1, the in-vehicle device 200 receives, from one or a plurality of the user terminals 100 existing in a predetermined range from the vehicle 20, the first information stored therein. Therefore, the first information of the specific user is stored in the individual setting information DB 260, at the point in time before the user who is going to get into the vehicle 20 actually gets into the vehicle 20. Then, when the specific user gets into the vehicle 20, the first information of the specific user stored in the individual setting information DB 260 is transmitted to the equipment ECU 400. As a result, various settings in the pieces of equipment mounted on the vehicle 20 are customized based on the first information of the specific user. Accordingly, the first information can be supplied to the equipment ECU 400 at an earlier stage as compared with a case where the first information of the specific user is transmitted to the vehicle after the specific user gets into the vehicle 20. As a result, the customization of the vehicle 20 based on the first information can be completed at an earlier stage.


In the present embodiment, the authentication process of specifying the specific user is performed based on the PIN code input to the in-vehicle device 200 by the specific user. The first information corresponding to the specific user specified by the authentication process is selected out of the first information stored in the individual setting information DB 260, and the selected first information is transmitted to the equipment ECU 400. Performing such an authentication process enabled the in-vehicle device 200 to grasp the specific user even when the information for identifying the user terminal 100 owned by the user to be specified as the specific user is not registered in advance with the in-vehicle device 200. Accordingly, the first information corresponding to the specific user can be transmitted to the equipment ECU 400. Note that an input code to be input to the in-vehicle device 200 for the authentication process is not necessarily limited to the PIN code. That is, the input code to be input to the in-vehicle device 200 is a code to be transmitted from the user terminal 100 to the in-vehicle device 200 together with the first information, the code being associated with the user ID.


Modified Embodiment 1

In the information management system 1, each user terminal 100 may transmit the first information in an encrypted state to the in-vehicle device 200. In this case, the in-vehicle device 200 stores the encrypted first information in the individual setting information DB 260. Then, in the in-vehicle device 200, when the specific user is specified by the authentication process, the controller 210 selects the first information of the specific user out of the first information stored in the individual setting information DB 260, and decrypts the selected first information. Furthermore, the controller 210 transmits the decrypted first information of the specific user to the equipment ECU 400. In this case, the controller 210 deletes, from the individual setting information DB, the first information of users other than the specific user stored therein in an encrypted state, without decrypting it. Thus, the encrypted first information is transmitted from each user terminal 100, whereby security of the first information can be improved


Modified Embodiment 2

As described above, in the information management system 1, when the specific user is specified by the authentication process, the information corresponding to users other than the specific user that is temporarily stored in the individual setting information DB 260 of the in-vehicle device 200 is deleted from the individual setting information DB 260. On the other hand, the information corresponding to the user specified as the specific user may be continuously stored in the individual setting information DB 260. In this case, in a case where one user is specified as the specific user to use the vehicle 20 and thereafter another user is specified as the specific user to use the same vehicle 20 the individual setting information corresponding to the one user and the individual setting information corresponding to the other user are stored in the individual setting information DB 260.



FIG. 6 is a table illustrating an example of a table configuration of the individual setting information DB 260 storing the user ID, the PIN code (PIN code of the user terminal 100 owned by the user), the first information and the second information of each of the users specified as the specific users. As illustrated in FIG. 6, in the individual setting information DB 260, the user ID, the PIN code, the first information and the second information corresponding to each of users who have been specified as the specific users of the vehicle 20 so far are stored in a state of being associated with one another. Note that an upper limit value of the number of users each indicated by these information items that cars be continuously stored in the individual setting information DB 260 may be set in advance.


In a case where the user (i.e., the user who has beers specified as the specific user in the past) corresponding to the user ID stored in the individual setting information DB 260 has gotten into the vehicle 20 again, the first information and the second information of the user that are stored in the individual setting information DB 260 are transmitted to the equipment ECU 400 from the in-vehicle device 200. At this time, in the in-vehicle device 200, when the specific user is specified by the authentication process, the controller 210 determines whether the information related to the specific user is stored in the individual setting information DB 260. This determination is made based on whether the same user ID (or the BIN code) as the user ID (or the PIN code) of the specific user specified this time is already stored in the individual, setting information DB 260.


In a case where it is determined that the information related to the specific user is stored in the individual setting information DB 260, the controller 210 transmits, to the equipment ECU 400, the first information and the second information that are stored in the individual setting information DB 260 in a state of being associated with the user ID (or the BIN code) of the specific user. Note that in this case, the communication is not performed between the in-vehicle device 200 and the management server 300 after the authentication process is performed, that is, the processes of S17, S18, and S19 in FIG. 5 are not performed.


As described above, in a case where the user who has been specified as the specific user in the past has gotten into the vehicle 20 again, the second information of the user can be supplied to the equipment ECU 400 from the in-vehicle device 200 without the necessity of receiving the second information from the management server 300. Therefore, not only the customization of the vehicle 20 based on the first information but also the customization of the vehicle 20 based on the second information can be completed at an earlier stage.


Second Embodiment

A schematic configuration of an information management, system according to the present embodiment is the same as that in the first embodiment. However, the present embodiment is different from the first embodiment in the contents of the authentication process of specifying a specific user that is performed in the in-vehicle device 200.


Hereinafter, an information process flow in an information management system 1 according to the present embodiment will be described with reference to FIG. 7. FIG. 7 is a sequence diagram illustrating an information process flow in the information management system 1 according to the present embodiment. Note that also in FIG. 7, two user terminals 100 existing in a predetermined range from a vehicle 20 are represented by a user terminal 100a and a user terminal 100b, similarly to FIG. 5. In FIG. 7, the user terminal 100a is a user terminal 100 owned by the user to be specified as a specific user.


In the present embodiment, an in-vehicle device 200 receives first information and a user ID from each of the user terminals 100 (100a and 100b) existing in the predetermined range from the vehicle 20, by short-range wireless communication (S21). Then, the in-vehicle device 200 stores, in an individual setting information DB 260, the first information and the user ID that are received from each of the user terminals 100 (S22). As in the first embodiment, at the point in time when the process of S22 is performed, the user to be specified as a specific user has not gotten into the vehicle 20 yet. Additionally, the first information of the other users who do not actually get into the vehicle 20 is also stored in the individual setting information DB 260, the other users existing around the vehicle 20.


Then, when the specific user gets into the vehicle 20, a two-dimensional code (e.g., QR code (registered trademark)) including a vehicle ID for identifying the vehicle 20 is displayed on an input/output I/F 207 of the in-vehicle device 200. When the two-dimensional code is displayed on the input/output I/F 207, the two-dimensional code is read by an input/output I/F of the user terminal 100a owned by the specific user who has gotten into the vehicle 20 (S23). Thus, the user terminal 100a owned by the specific user acquires the vehicle ID.


Note that the process of displaying the two-dimensional code on the input/output I/F 207 of the in-vehicle device 200 is performed by a controller 210. The display code displayed on the input/output I/F 207 is not necessarily limited to the two-dimensional code. That is, the display code to be displayed on the input/output I/F 207 is a code including the vehicle ID, the code being a code being able to be read by the user terminal 100.


When the user terminal 100a owned by the specific user acquires the vehicle ID, the user terminal 100a transmits the user ID (the user ID of the specific user) and the vehicle ID to the management server 300 through the network N1 (S24). When the management server 300 receives the user ID and the vehicle ID from the user terminal 100a, the management server 300 specifies the vehicle 20 that the specific user has gotten into, based on the vehicle ID. Then, the management server 300 transmits the user ID received from the user terminal 100a, to the in-vehicle device 200 mounted on the specified vehicle 20 through the network N1 (S25).


When the in-vehicle device 200 receives the user ID transmitted from the management server 300, in the in-vehicle device 200, the authentication process of specifying the specific user is performed (S26). The authentication process is performed based on the user ID received from the management server 300. Specifically, among users whose first information is stored in the individual setting information DB 260, a user corresponding to the same user ID as the user ID received from the management server 300 is determined as the specific user. Then, in the in-vehicle device 200, the first information of the specific user specified by the authentication process is selected out of the first information stored in the individual setting information DB 260 (S27). That is, the first information associated with the same user ID as the user ID received from the management server 300 is selected as the first information of the specific user. Furthermore, the in-vehicle device 200 transmits the selected first information (the first information of the specific user) to the equipment ECU 400 (S27). Note that, in the in-vehicle device 200, as in the first embodiment, when the specific user is specified by the authentication process, the information (the first information, and the user IDs) corresponding to the users other than the specific user that is temporarily stored in the individual setting information DB 260 is deleted from the individual setting information DB 260.


In the management server 300, the second information corresponding to the user ID of the specific user is selected out of the second information stored in the second information DB 330 (S29). That is, the second information associated with the same user ID with the user ID received from the user terminal 100a is selected as the second information of the specific user. Furthermore, the management server 300 transmits the selected second information (the second information of the specific user) to the in-vehicle device 200 through the network N1 (S30). Then, the in-vehicle device 200 transmits, to the equipment ECU 400, the second information of the specific user received from the management server 300 (S31). Note that, in the present embodiment, the user ID corresponds to “user identification information” according to the present disclosure, and the vehicle ID corresponds to “vehicle identification information” according to the present disclosure.


Also in the present embodiment, performing the above-descried authentication process in the in-vehicle device 200 enables the in-vehicle device 200 to grasp the specific user even when the information for identifying the user terminal 100 owned by the user to be specified as the specific user is not registered in advance with the in-vehicle device 200. Therefore, the first information corresponding to the specific user can be transmitted to the equipment ECU 400.


Additionally, also in the present embodiment, the effects by the information management system 1 can be obtained, as in the first, embodiment. Furthermore, Modified Embodiment 1 and Modified Embodiment 2 of the first embodiment as described above can be also applied to the second embodiment.
