Description

The disclosed embodiments relate to an information processing device, an information processing system, and an information processing method.

Conventionally, a navigation system for group activities is known (see Patent Document 1, for example). In such a system, for example, when one of the group vehicles uploads information such as the current location and the destination to the server device, the server device updates the homepage regarding the information of the one vehicle.

Other vehicles of the group vehicle acquire information of one vehicle by downloading the information posted on the home page. By setting, for example, the destination data included in such information, the group vehicles can travel so as to meet at the same destination.

However, the conventional technology has room for further improvement in terms of facilitating and utilizing various information exchanges during group activities.

For example, in the conventional technology, it is difficult to share information among group vehicles unless communication between each vehicle and the server device is always established.

Further, for example, when a group of vehicles moves in a row, the group may be divided depending on the timing of the signal or a vehicle entering between the group vehicles. Also, for example, the preceding vehicle may suddenly want to stop at an unscheduled location for a break or the like.

In such a case, the preceding vehicle must stop and wait for the following vehicle to join the vehicle. Service) applications are often used.

However, it is not possible to share information using such SNS applications with group members who do not use such SNS applications or with members who do not carry smartphones in the first place. In addition, the conventional technology cannot reflect the exchanges exchanged through such SNS applications, for example, in the navigation system.

One aspect of the embodiments has been made in view of the above, and provides an information processing device, an information processing system, and an information processing method that facilitate and utilize various information exchanges during group action. for the purpose.

An information processing device according to an aspect of an embodiment is an information processing device provided in a vehicle and having a control unit. The control unit acquires information about other vehicles that cooperate during the group action based on the input information about the group action. Further, the control unit executes information processing related to the group behavior based on the acquired information related to the other vehicle.

According to one aspect of the embodiment, it is possible to facilitate and utilize the exchange of various information during a group action.

Further, hereinafter, the information processing apparatus according to the embodiment is assumed to be the in-vehicle apparatus 10 mounted in the vehicle V. As shown in FIG. Also, hereinafter, "app" is an abbreviation for application software.

Further, hereinafter, a plurality of components having substantially the same functional configuration may be distinguished by attaching different numbers with hyphens after the same reference numerals. For example, a plurality of configurations having substantially the same functional configuration are distinguished as in-vehicle device 10-1, in-vehicle device 10-2, . . . as necessary. However, when there is no particular need to distinguish between a plurality of constituent elements having substantially the same functional configuration, only the same reference numerals are used. For example, when there is no particular need to distinguish between the in-vehicle device 10-1, the in-vehicle device 10-2, .

In the following, it is assumed that the vehicle ID of vehicle V-1 is "vehicle ID-1". It is also assumed that the vehicle ID of vehicle V-2 is "vehicle ID-2". It is also assumed that the vehicle ID of vehicle V-3 is "vehicle ID-3".

In the following, it is assumed that the user who gets on the vehicle V-1 is "user U-1". It is also assumed that the user who gets on the vehicle V-2 is "user U-2". It is also assumed that the user who gets on the vehicle V-3 is "user U-3".

First, an overview of an information processing method according to an embodiment will be described with reference to FIGS. 1 to 4. FIG. FIG. 1 is a schematic explanatory diagram of an information processing method according to an embodiment. Moreover, FIG. 2 is a figure which shows schematic structure of the vehicle-mounted apparatus 10 which concerns on embodiment. Also, FIG. 3 is an example of an application database that the server device 100 has. Also, FIG. 4 is an explanatory diagram of the image and operation of the bulletin board.

In this embodiment, it is assumed that vehicles V-1, V-2, and V-3 go on a group trip. As shown in FIG. 1 , an information processing system 1 according to the embodiment includes a plurality of in-vehicle devices 10 and a server device 100 .

The in-vehicle device 10 is a computer mounted in each vehicle V. FIG. The server device 100 is a travel management server in this embodiment, and is realized as a cloud server, for example.

Then, in the information processing method according to the embodiment, first, the server device 100 performs grouping by common ID (step S1). After that, each in-vehicle device 10 shares information by so-called container-type virtualization based on the common ID (step S2).

A detailed description will be given from step S1. In step S1, the common ID is, for example, a travel ID for a group trip. A trip ID corresponds to a group ID that identifies a group in a group trip.

A travel ID is issued by server device 100 when one of the members of the group, for example, sets a travel plan including date and time, waypoints, destinations, participating members, etc. to server device 100 via a personal terminal such as a smartphone. . The issued travel ID is transmitted to each personal terminal of the members of the group and registered in each personal terminal.

Then, when each member of the group carries a personal terminal and gets into each vehicle V, the in-vehicle device 10 establishes a communication connection with the personal terminal by short-range wireless communication or the like. Then, the in-vehicle device 10 confirms whether or not the connected personal terminal has a common ID.

If the personal terminal has a travel ID registered in its own device as a common ID, the personal terminal responds to the in-vehicle device 10 with the travel ID. Then, the in-vehicle device 10 outputs the travel ID received from the personal terminal to the bulletin board 12a owned by the own device.

A travel ID is associated with a group travel application that can operate on the in-vehicle device 10 according to the travel ID. When the travel ID is output to bulletin board 12 a , in-vehicle device 10 downloads the “group travel application” associated with the travel ID from server device 100 . When the in-vehicle device 10 activates the group travel application, the vehicle ID, which is the identifier of the vehicle V, is registered on the server device 100 via the application.

Then, when the vehicle IDs for each of the plurality of vehicles V are registered for the same travel ID, the server device 100 assigns each vehicle V in the same group corresponding to the same travel ID to other vehicles in the group. It transmits the network ID of the vehicle 30d. A network ID is an identifier on a network such as an IP (Internet Protocol) address or a MAC (Media Access Control) address.

After that, each in-vehicle device 10 performs direct inter-vehicle communication via the network ID to exchange various information during group action via the aforementioned bulletin board 12a. In such an exchange, each in-vehicle device 10 has an image of sharing its own bulletin board 12a virtually as one bulletin board 12a within the same group. In addition, the various information includes, for example, data indicating the situation of each vehicle V obtained from an in-vehicle sensor of each vehicle V, messages exchanged by occupants of the vehicle V through SNS applications, and the like. A specific image of the bulletin board 12a will be described later with reference to FIG.

By sharing such information, as shown in FIG. 1, for example, among vehicles V moving in a group, when vehicle V-1 makes an unexpected left turn toward restaurant 300, vehicles V-2 and V- 3 refers to the winker state of the vehicle V-1 output to the bulletin board 12a (see arrow a1 in the figure), and can reflect it in a navigation device or the like in real time.

A more specific description will be given with reference to FIGS. 2 to 4. FIG. As shown in FIG. 2 , the in-vehicle device 10 has a communication section 11 , a storage section 12 and a control section 13 . The communication unit 11 transmits and receives various types of information to and from the node 30 and the server device 100 . The node 30 includes, for example, an ECU (Electronic Control Unit) 30a, an in-vehicle sensor 30b, a personal terminal 30c, another vehicle 30d, a navigation device 30e, and the like.

The communication unit 11 is implemented by, for example, a NIC (Network Interface Card) or the like. The communication unit 11 communicates with the server device 100, the personal terminal 30c, and another vehicle 30d via a mobile phone network based on LTE (Long Term Evolution).

Moreover, the communication part 11 communicates with vehicle-mounted apparatuses, such as ECU30a and the vehicle-mounted sensor 30b, via CAN (Controller Area Network). In addition, the communication unit 11 is a personal terminal 30c via NFC (Near Field Communication), UWB (Ultra Wide Band), BLE (Bluetooth (registered trademark) Low Energy), Wi-Fi (registered trademark), It communicates with other vehicles 30d, ECU 30a, and in-vehicle sensors 30b.

The storage unit 12 has a bulletin board 12a and a container unit 12b. The bulletin board 12a functions as a broker using, for example, MQTT (Message Queuing Telemetry Transport) adopting the Publish/Subscribe method. The bulletin board 12a associates each data received from each node 30 with a TOPIC (a concept such as the theme name of data, which is defined and used within a group or system) and posts the TOPIC. The data posted on the bulletin board 12a can be freely obtained by the node 30 that wishes to refer to it. Also, if the node 30 sets a data update notification for the relevant TOPIC in advance, it can receive notification every time the data of the TOPIC is updated. In addition, the data posted on the bulletin board 12a is added with data on the generation time of the data. Also, temporal processing such as display of time relating to display information based on the data and rearrangement of information is performed.

The container section 12b is configured by a storage area allocated to the storage section 12, and a plurality of containers 12ba determined in advance by design are formed. One application is stored in one container 12ba. The application is acquired from the server device 100 and set (stored) in the container 12ba. In addition, unnecessary applications are erased from the container 12ba, and the container 12ba becomes an empty container.

Server device 100 has an application database shown in FIG. The application database is a database in which various applications stored in the container 12ba are registered. "App ID" is the identification code of the app and the primary key of each record in the database.

"Application name" is the name of the application. Although this item is used for display, for example, it may not be essential. “Compatible in-vehicle system” is information for selecting an application according to the hardware and software of the in-vehicle device 10 .

“Usage” is information for selecting an application according to the purpose of use. In the case of this embodiment, it becomes a group car trip, and is provided via the in-vehicle device 10 from an application that is set in advance on the personal terminal 30c.

The “application main body” is the program main body of the application, and includes a bulletin board data generation program that converts data from the in-vehicle sensor 30 b and the like into TOPIC data, and a control program for the in-vehicle device 10 and the node 30 .

"Bulletin board generation information" is information for generating the bulletin board 12a corresponding to the application. The information includes various information necessary for generating a bulletin board, such as the TOPIC format and the types of normal data and repeated data. In this embodiment, since there are multiple vehicle data, various vehicle data are repetitive data.

The "message" and the like are information and the like of the in-vehicle sensor 30b, the node 30, etc., which are required to be added when the functions are enhanced.

Returning to the description of FIG. The controller 13 has a container controller 13e. The container control unit 13e functions as a container engine that stores/deletes an application in the container 12ba of the container unit 12b and executes the application.

The operation of the bulletin board 12a using the container unit 12b will be described in order. do.

Then, the server device 100 distributes the travel ID and travel information (the main purpose of this is for each group member to confirm the travel details) to the personal terminals 30c of the group members.

Then, when each member gets on the vehicle, the in-vehicle device 10 and the personal terminal 30c establish communication connection by short-range communication. After establishing the communication connection, the in-vehicle device 10 reads the travel ID and executes the following two processes corresponding to the travel ID. As a first process, the in-vehicle device 10 detects available (connected) nodes 30 (including the ECU 30a and the in-vehicle sensor 30b of the own vehicle). As the second process, the vehicle-mounted device 10 transmits the node information of each node 30 detected in the first process and the vehicle-mounted device information to the server device 100 .

The in-vehicle device 10 has, as basic software, software for performing the above two processes when acquiring format data compatible with the information processing system 1, here travel ID data.

Then, the server device 100 transmits bulletin board information regarding control of the bulletin board 12 a , container information regarding control of the container unit 12 b , information necessary for communication between vehicles, and a group travel application to each in-vehicle device 10 . At this time, server device 100 determines a TOPIC format that can be generated and used by each vehicle based on the own vehicle device information and node information from each vehicle, and generates bulletin board information.

Moreover, the server device 100 generates an application suitable for each vehicle based on these pieces of information. As shown in FIG. 3, the server device 100 has a plurality of applications corresponding to each vehicle, from which selection is made. That is, the application performs a process of generating TOPIC-format data based on data from sensors and the like that can be acquired by the in-vehicle device 10, and causes the in-vehicle device 10 to perform various controls based on data posted on the bulletin board 12a. For example, the application causes the in-vehicle device 10 to perform control such as displaying the route, the status of other vehicles, etc. on the navigation device 30e. In some cases, the application provides data for controlling the vehicle and various in-vehicle devices.

In addition, when there is a shortage of nodes 30 such as the in-vehicle sensor 30b, there is no application that can be applied due to the shortage, only TOPIC data can be provided, or only low-function applications can be used, the server device 100 adds the missing node 30 The recommended information is provided to the in-vehicle device 10 .

The in-vehicle device 10 sets up the bulletin board 12 a based on the bulletin board information from the server device 100 . Also, the in-vehicle device 10 mounts the delivered application in the container 12ba of the container unit 12b and activates the application. The in-vehicle device 10 also provides bulletin board information and container (implemented application) information to each node 30 so that data can be exchanged with each node 30 and cooperative operations can be performed. Note that the in-vehicle device 10 can also provide corresponding applications to each node 30 as necessary.

Then, the in-vehicle device 10 exchanges data with each vehicle based on the settings described above. Such exchanges are based on vehicle-to-vehicle communication, but can also be performed from the server device 100 . Then, the in-vehicle device 10 displays the status of the other vehicle on the navigation device 30e, for example, based on this exchange.

Specifically, the in-vehicle device 10 accesses the bulletin board 12a of the other vehicle, acquires necessary TOPIC data, posts (updates) it on the bulletin board of the own vehicle, and uses the data for various controls. The bulletin board 12a of the other vehicle may be a bulletin board 12a formed in the server device 100 as well as the other vehicle. Further, the in-vehicle device 10 processes the data acquired from the node 30 of the own vehicle (for example, the in-vehicle sensor 30b) into TOPIC data, and posts it on the bulletin board 12a.

A more specific image of the bulletin board 12a is shown in FIG. As shown in FIG. 4, on the bulletin board 12a, an input TOPIC for each vehicle is posted in association with the travel ID. In the example shown in the figure, the input TOPIC includes a vehicle ID for each vehicle linked to the travel ID, vehicle status information (vehicle position, vehicle speed, blinker status), SNS text, and the like.

In addition, the bulletin board 12a displays the travel name corresponding to the travel ID and the output TOPIC corresponding to the input TOPIC for each vehicle. In the example shown in the figure, the output TOPIC includes vehicle icon information, position information, progress prediction information, message text, etc. for each vehicle associated with the trip name (that is, trip ID). In addition, in the example of FIG. 4, each output TOPIC is associated with a navigation device 30e as an output node.

Then, for example, the in-vehicle device 10 of the c vehicle shown in FIG. Posted in the output TOPIC as vehicle progress prediction information. Similarly, the c-vehicle SNS text corresponding to the c-vehicle ID is converted by the application so that it can be used in the navigation device 30e, and posted as the c-vehicle message text on the output TOPIC.

Then, the application controls the navigation device 30e, and uses c vehicle icon information, c vehicle position information, c vehicle progress prediction information, and c vehicle message text posted in the output TOPIC to cause the navigation device 30e to perform navigation display. .

Thus, the information processing method according to the embodiment is an information processing method executed by the in-vehicle device 10 provided in the vehicle V. FIG. The in-vehicle device 10 acquires information about the other vehicle 30d that performs cooperative behavior during the group behavior based on the input information about the group behavior. In addition, the in-vehicle device 10 executes information processing regarding the group behavior based on the acquired information regarding the other vehicle 30d.

Therefore, according to the information processing method according to the embodiment, it is possible to facilitate and utilize the exchange of various information during a group action. Hereinafter, a configuration example of the information processing system 1 to which the information processing method according to the embodiment is applied will be described more specifically.

FIG. 5 is a block diagram showing a configuration example of the information processing system 1 according to the embodiment. It should be noted that FIG. 5 shows only the constituent elements necessary for explaining the features of this embodiment, and omits the description of general constituent elements.

The authentication unit 13 a acquires information for authenticating each node 30 from each node 30 , authenticates the node 30 connected to the in-vehicle device 10 based on this information, and authenticates each node 30 and the in-vehicle device 10 . Enable communication connection. For example, when the in-vehicle device 10 is powered on, the authentication unit 13a acquires information for authentication from each communicable node 30, and based on the information, the node connected to the in-vehicle device 10 Authenticate 30. The information for authenticating the node 30 is, for example, information regarding BLE pairing in the case of BLE. Also, when a node 30 is newly connected, the authentication unit 13a authenticates the newly connected node 30 .

Further, the authentication unit 13a sets the node 30 that can read and write the bulletin board 12a. When authenticating the node 30, the authentication unit 13a sets the node 30 to which the data stored in the bulletin board 12a is to be distributed based on the distribution request information from the node 30, for example.

The distribution request information may be information requesting distribution of data relating to all TOPICs stored on the bulletin board 12a, or information requesting distribution of data relating to some of the TOPICs stored on the bulletin board 12a. may The distribution request information may include information designating the TOPIC to be distributed.

Also, the authentication unit 13a sets a TOPIC for data acquired from the node 30 that has been authenticated. Multiple TOPICs may be set for one node 30 .

The acquisition unit 13b acquires data from each node 30 that has been authenticated. The acquisition unit 13b also acquires various data and applications from the server device 100 .

The conversion unit 13c converts the data acquired from the node 30 into a data display format on the bulletin board 12a using a corresponding application. In this embodiment, such a data posting format can be distributed to each node 30 using, for example, MQTT, and each node 30 can grasp the meaning of each data and use it. output format. Further, the conversion unit 13c causes the bulletin board 12a of the storage unit 12 to store the converted data.

The adjuster 13 d plays a role of a coordinator that adjusts the priority of each data item on the bulletin board 12 a according to the importance of each node 30 . In this embodiment, the importance of each node 30 is higher in the order of "safety>safety>entertainment", and the priority of processing for these types of data is determined according to this importance. The processing priority is the order of processing start, resource allocation, and the like. Determining according to the degree of importance means that the more important the data type, the higher the priority, that is, the higher the priority.

The container control unit 13e performs various controls on the container unit 12b in the storage unit 12, and stores an application acquired by the acquisition unit 13b from the server device 100 as necessary in the container unit 12b. is deleted from the container unit 12b, and the application stored in the container unit 12b that needs to be executed is executed by the application execution unit 13f. The container control unit 13e performs processing according to the container engine program stored in the storage unit 12, and realizes these operations as a container engine.

The application executing unit 13f executes an application selected to be executed (started) by the container control unit 13e. By executing these applications, the application execution unit 13f generates an input TOPIC in a predetermined format based on the acquired data and stores it in the bulletin board 12a, stores an output TOPIC generated based on the input TOPIC in the bulletin board 12a, and the like. implement the action. Further, the application execution unit 13f realizes operations such as causing the distribution unit 13g to distribute the output TOPIC stored in the bulletin board 12a to the corresponding output node by executing these applications.

The distribution unit 13g distributes the data of the input TOPIC and the output TOPIC stored in the bulletin board 12a to the node 30 of the distribution destination. In other words, the distribution unit 13g causes the node 30 coming to the bulletin board 12a to obtain the data. For example, the distribution unit 13g distributes the output TOPIC generated by the application execution unit 13f to the corresponding node 30 as an output node.

Next, a specific example of information processing according to the present embodiment based on the above description will be described with reference to FIGS. 6 to 9. FIG. FIG. 6 is an explanatory diagram (part 1) of a specific example of information processing according to the embodiment; FIG. 7 is an explanatory diagram (part 2) of a specific example of information processing according to the embodiment. FIG. 8 is an explanatory diagram (part 3) of a specific example of information processing according to the embodiment. FIG. 9 is an explanatory diagram (part 4) of a specific example of information processing according to the embodiment.

In this case, as shown in FIG. 6, while the vehicles V-1, V-2, and V-3 are moving as a group as scheduled, the bulletin board 12a of each vehicle-mounted device 10 displays the current position of each vehicle V. etc. are posted, and the current position of each vehicle V is displayed on the navigation device 30e of each vehicle V accordingly.

The data posted on the bulletin board 12a of each in-vehicle device 10 is converted into a format that can be used by the application of each in-vehicle device 10 by the corresponding application stored in the container unit 12b as described above.

In addition, since the current position data of each vehicle V is data that changes from moment to moment, based on the position-related data from the position sensors (nodes), the latest data is sequentially registered on the bulletin board 12a, for example, at predetermined intervals. . In addition, the newest data is sequentially registered for other similar data.

Here, user U-1 who is a passenger of vehicle V-1 transmits a message "Let's have dinner here" on the SNS application of personal terminal 30c, etc., and vehicle V-1 is manually operated by the driver. It is assumed that an unscheduled left turn is made based on the operation or the automatic driving action.

Then, the control unit 13 of the in-vehicle device 10-1 converts the message "Let's have dinner here" into a predetermined format and displays it on the bulletin board 12a of the in-vehicle device 10-1 using the corresponding application stored in the container 12ba. The converted data "let's eat here" is output to "user U-1 SNS" (see arrow a2 in the figure). Similarly, the control unit 13 of the in-vehicle device 10-1 converts the vehicle travel data "left turn" into a predetermined format by using the corresponding application stored in the container unit 12b and displays it on the bulletin board 12a of the in-vehicle device 10-1. The conversion data "left turn" is output to "vehicle ID-1, winker state" (see arrow a3 in the figure).

Then, the control unit 13 of the in-vehicle device 10-2 registers (stores) each of these newly acquired data in the bulletin board 12a of its own device (see arrows a4 and a5 in the drawing).

Similarly, the in-vehicle device 10-3, through vehicle-to-vehicle communication via the communication unit 11, transmits the data “here Let's have a meal at" and acquires the data "turn left" of the TOPIC "vehicle ID-1, winker state". Then, the control unit 13 of the in-vehicle device 10-3 registers these newly acquired data on the bulletin board 12a of the own device (see arrows a6 and a7 in the drawing).

Note that the in-vehicle device 10-3 may acquire each data that the in-vehicle device 10-2 has acquired from the in-vehicle device 10-1 from the in-vehicle device 10-2 through inter-vehicle communication. Similarly, the in-vehicle device 10-2 may acquire each data that the in-vehicle device 10-3 has acquired from the in-vehicle device 10-1 from the in-vehicle device 10-3 through inter-vehicle communication.

Then, when each data of the arrows a4 to a7 is registered on the bulletin board 12a, as shown in FIG. Using the current position data of each vehicle registered in the , TOPIC "User U-1/SNS" data, and TOPIC "Vehicle ID-1/Winker status" data, the display reflecting these data is displayed on the navigation screen. I do.

Specifically, as shown in FIG. 8, the navigation device 30e of the in-vehicle device 10-2, based on the current position data of the host vehicle registered on the bulletin board 12a of the in-vehicle device 10-2, is displayed on the map. display an own vehicle mark indicating "you" at the position of the own vehicle. Further, the navigation device 30e of the in-vehicle device 10-2 moves the vehicle V-1 to the corresponding position on the displayed map based on the current position data of the vehicle ID-1 registered in the bulletin board 12a of the in-vehicle device 10-2. A mark indicating (in-vehicle device 10-1) is displayed. Further, the navigation device 30e of the in-vehicle device 10-2 displays the current position data of the host vehicle and the vehicle ID-1 registered on the bulletin board 12a of the in-vehicle device 10-2, the data of the TOPIC "user U-1 SNS" "here Let's have a meal at”, based on the data “left turn” of the TOPIC “vehicle ID-1, turn signal status”, the vehicle V- 1 has made a left turn, and displays the message "Let's have dinner here" sent by user U-1.
