2. Operation FIG. 4 is a sequence chart illustrating the operation of the server 20. The sequence of FIG. 4 is started, for example, when a predetermined data is received from the vehicle-mounted device 10. In the following, functional elements such as the route estimation unit 23 will be described as the main body of processing, but in these explanations, hardware elements such as the processor 201 executing software such as a server program cooperate with other hardware elements. It means to work and perform processing.

In step S101, the route estimation unit 23 estimates the destination of the vehicle V. The destination is estimated using the data transmitted from the on-board unit 10 or other device. The data used for estimating the destination are, for example, data indicating the user's schedule (activities planned to be performed by the user in the future), data indicating the user's action history, data indicating the current position of the user (vehicle V), or car. It is data indicating the destination set by the navigation. The "other device" referred to here is a device that communicates with the server 20 via the vehicle-mounted device 10, or a device that communicates with the server 20 via the Internet or the like without the vehicle-mounted device 10. As an example, an example of acquiring information indicating a user's schedule (hereinafter referred to as "schedule information") from another device (for example, a smartphone owned by the user) will be described. The communication unit 21 receives the schedule information of the user from the smartphone of the user in the car V. Identification information of the automobile V is added to this schedule information. The route estimation unit 23 estimates the destination of the vehicle V from the received schedule information. For example, if the information "swimming at the ABC school from 3:00 pm" is registered as the user's schedule information today, the route estimation unit 23 estimates that the "ABC school" is the destination. As another example, an example of acquiring a destination from a car navigation device will be described. The user inputs the destination into the vehicle-mounted device 10 which is a car navigation device. The vehicle-mounted device 10 transmits the input data indicating the destination to the server 20. The communication unit 21 of the server 20 receives data indicating the destination of the vehicle V from the vehicle-mounted device 10. The route estimation unit 23 estimates the destination using this data. In this example, since the data received from the vehicle-mounted device 10 indicates the destination itself, it is more appropriate to specify the destination than to estimate the destination.

In step S102, the priority determination unit 24 determines the priority of the content. Specifically, the priority determination unit 24 determines the priority using the priority table. The priority table is a table in which the relative priorities of a plurality of contents are recorded in association with the destination. As will be described later, since the priority of contents may be related to the output order of contents, the priority table can be said to be an example of a table in which the relative output orders of a plurality of contents are recorded. The priority table is stored in the storage unit 22.

FIG. 5 is a diagram illustrating a priority table. In this table, the rows correspond to the content and the columns correspond to the destination. In this example, the contents include "Tomorrow's schedule", "Today's schedule", "Tomorrow's weather", "Today's weather", "Scheduled departure time", "Congestion estimation", and "Schedule-related information other than the above". , "Destination-related information other than the above", and "email" are included. "Tomorrow's schedule" and "Today's schedule" are the schedules scheduled for tomorrow and today by the user. "Tomorrow's weather" and "Today's weather" are weather information for tomorrow and today. The "scheduled departure time" means that if there is a schedule to go to the second destination after going to the first destination, the first destination must be departed to go to the second destination. It is a time when it does not become. "Congestion estimation" is information on traffic congestion that is estimated to occur on the route from the current location to the destination. "Schedule-related information other than the above" is information related to the user's schedule and is information that the server 20 determines to be useful. One example is a shopping proposal. “Destination-related information other than the above” is information related to the destination and is information that the server 20 determines to be useful. As an example, tourist information around the destination corresponds to this. "Email" is information that reads out the e-mail received by the user.

In this example, the destinations are "home", "destination estimated from schedule", "destination estimated from user's behavior history", "destination set by car navigation", and "destination unknown". "are categorized. "Home" is the user's home. "Destination estimated from schedule", "Destination estimated from user's behavior history", and "Destination set by car navigation" are classified based on the data on which the destination is estimated. be. "Destination unknown" is a case where the destination is unknown.

In the priority table, information indicating whether or not the content is delivered or the relative priority when the content is delivered is recorded in each cell. In the example of FIG. 5, when the destination is "home", "today's schedule" and "today's weather" are not delivered to the user. This is because it is presumed that the user is often not interested in the future schedule and the weather when returning home. For contents other than "Today's schedule" and "Today's weather", from the highest, "Tomorrow's schedule", "Estimated departure time", "Tomorrow's weather", "Congestion estimation", "Schedule related to other than the above" Priority is set in the order of "information", "destination-related information other than the above", and "email".

See FIG. 4 again. In step S103, the content selection unit 25 selects the content to be delivered to the user from the plurality of contents. As will be described later, the selection of the content is repeated depending on the situation, but at first, all the contents other than the content recorded as "not delivered" in the priority table are selected as the contents to be delivered.

In step S104, the content selection unit 25 calculates the time required to output the selected content on the vehicle-mounted device 10. In this embodiment, each content is accompanied by audio output. For example, "Tomorrow's schedule" and "Today's schedule" include audio output that guides the schedule, such as "I have a swimming schedule at ABC school from 3:00 pm." "Tomorrow's weather" and "Today's weather" include "Tomorrow's weather in Tokyo is sunny and sometimes cloudy, with a 20% chance of precipitation, a minimum temperature of 5 ° C, a maximum temperature of 12 ° C, and it gets cold in the evening." Includes audio output to guide information. In addition, "congestion estimation", "schedule-related information other than the above", and "destination-related information other than the above" include audio output for guiding various information. In addition, the "mail" includes reading out at least one item of the reception time, the sender, the title, and the text contained in the e-mail sent to the user. The content selection unit 25 calculates the time required to output the content on the vehicle-mounted device 10 by using, for example, the amount of data of the selected content. Regarding the conversational content, the content selection unit 25 estimates the time required for conversation with the user, and includes the estimated time in the time required to output the content on the vehicle-mounted device 10. Further, when an interval for not outputting the content is provided between the two contents, the time of this interval may be included in the time required for the content to be output by the vehicle-mounted device 10.

In step S105, the route estimation unit 23 estimates the time required to reach the destination. Known techniques are used to estimate the time required from the current location to the destination. The estimated time of arrival at the destination is called the "estimated arrival time". Further, the current location of the vehicle-mounted device 10 (that is, the current location of the vehicle V) is output from a GPS receiver, a gyro sensor, an electronic compass, an acceleration sensor, a vehicle speed signal receiver (all not shown) and the like included in the vehicle-mounted device 10. Calculated using information.

In step S106, the content selection unit 25 determines whether the time required to output the selected content is shorter than the time required to reach the destination. When it is determined that the time required to output the content is longer than the time required to reach the destination, the content selection unit 25 shifts the process to step S103 again. During the movement until a certain user reaches a certain destination, the content having the lowest priority among the already selected contents is deselected in the second and subsequent steps S103. For example, after the 1st to 7th content is selected in the first step S103, the 7th content is deselected and the 1st to 6th content is selected in the second step S103. .. When it is determined that the time required to output the content is shorter than the time required to reach the destination, the content selection unit 25 shifts the process to step S107.

In step S107, the order determination unit 27 determines the order in which the selected contents are distributed. As an example, the ordering unit 27 determines to deliver the selected content in a priority order (higher priority content first). Alternatively, the order determination unit 27 may determine the order of the contents based on information other than the priority. As an example, the order determination unit 27 determines the order of the contents using the order table. The sequence table is another example of a table in which the relative order when outputting multiple contents is recorded. The sequence table is stored in the storage unit 22.

FIG. 6 is a diagram illustrating an order table. In this example, "Tomorrow's schedule", "Today's schedule", "Tomorrow's weather", "Today's weather", "Scheduled departure time", "Congestion estimation", "Schedule-related information other than the above", "The above The relative order is recorded for a plurality of contents such as "destination-related information other than" and "mail". The order of output is "Today's schedule", "Today's weather", "Scheduled departure time", "Congestion estimation", "Email", "Schedule-related information other than the above", "Purpose other than the above" from the previous one. The order is "land-related information", "tomorrow's schedule", and "tomorrow's weather". For example, if all the contents other than "Today's schedule", "Today's weather", and "Scheduled departure time" are selected, these contents will be "Congestion estimation", "Email", etc. from the previous ones. It is output in the order of "schedule-related information other than the above", "destination-related information other than the above", "tomorrow's schedule", and "tomorrow's weather".

In the example of FIG. 6, the relative order when outputting a plurality of contents is uniformly determined regardless of the classification of the destination. In another example, the relative order when outputting a plurality of contents may be determined for each destination.

See FIG. 4 again. In step S108, the distribution schedule determination unit 26 determines a schedule for distributing the selected content. As an example, the distribution schedule determination unit 26 determines the schedule so that the distribution of the content is started from the time obtained by subtracting the time required to output the content from the estimated arrival time. Specifically, if the estimated arrival time is 4:00 pm and it is calculated that it takes 30 minutes to output the content, the distribution schedule determination unit 26 starts outputting the content from 3:30 pm. To determine.

As another example, the distribution schedule determination unit 26 determines the distribution schedule of the content having a strong relationship with the geographical location based on the estimated arrival time at that point, and then determines the distribution schedule of the remaining content. do. For example, consider an example in which a total of five contents are selected, and the content having the third output order is a tourist guide around the position P1 on the route. The distribution schedule determination unit 26 determines to start the output of the content at a time obtained by subtracting the time required for the output of the content and the predetermined time from the estimated arrival time at the position P1. Specifically, when it is estimated that the position P1 will be reached at 3:30 pm and it takes 10 minutes to output the content, the distribution schedule determination unit 26 will perform the distribution schedule determination unit 26 from 3:30 pm to 10 minutes. And it is decided to start the output of the content at 3:17 pm after subtracting 3 minutes (an example of a predetermined time). After that, the distribution schedule determination unit 26 determines the distribution schedule of the contents in the 1st and 2nd order based on 3:17 pm, and further determines the distribution schedule of the contents in the 4th to 5th order in the afternoon. It will be decided based on 3:27. When determining the delivery time by this algorithm, in step S106, although it is determined that the time required to output the selected content is shorter than the time required to reach the destination, the destination is reached. There is a possibility that the output of the content will not be completed by the time it reaches. In this case, the distribution schedule determination unit 26 performs exception handling for completing the output of the content by the time the destination is reached. This exception handling is, for example, a processing of changing the order of outputting the contents, or a processing of removing the selection of the contents having the lowest priority.

In the above process, the schedule for delivering the content is determined. The estimated arrival time at the destination changes from moment to moment depending on the road congestion and the moving speed of the vehicle V. In order to respond to the change in the estimated arrival time, the server 20 may repeatedly execute the processes of steps S103 to S108. When the processes of steps S103 to S108 are repeatedly executed, the content to be delivered is reduced when the arrival is likely to arrive earlier than the initial estimation, and the content to be delivered is increased when the content is likely to arrive later than the initial estimation.

In step S109, the distribution unit 29 determines whether it is time to start distribution of the content. The server 20 has a time measuring unit (not shown) for measuring the current time, and the distribution unit 29 acquires the current time from this time measuring unit. The distribution unit 29 compares the distribution schedule determined in step S108 with the current time, and determines whether it is time to start distribution of the content. If it is determined that it is not yet the time to start the distribution of the content, the distribution unit 29 waits until it is the time to start the distribution of the content. When it is determined that it is time to start the distribution of the content, the distribution unit 29 shifts the process to step S110.

In step S110, the distribution unit 29 asks the user whether the content may be distributed. Specifically, the distribution unit 29 transmits data for confirming to the user whether the content may be distributed to the vehicle-mounted device 10. According to this data, the vehicle-mounted device 10 confirms with the user whether the content may be distributed, and transmits the answer to the server 20. For example, the voice output unit 12 of the vehicle-mounted device 10 outputs a voice "Are you sure you want to distribute the tourist information in the vicinity of Y town in X city?". In response to this, the user replies "please" or "does not need", and the voice input unit 13 transmits this voice data to the server 20. The conversation control unit 28 analyzes the voice data of the response from the user, and outputs the result, that is, information indicating whether or not to distribute the content to the distribution unit 29. When it is confirmed that the content is not distributed, the distribution unit 29 excludes the content from the target to be distributed (that is, the content is not distributed). The process of step S110 may be omitted.

In step S111, the distribution unit 29 distributes the content. The distribution unit 29 transmits data for outputting the content to the vehicle-mounted device 10. The audio output unit 12 of the vehicle-mounted device 10 outputs audio related to the content. For conversational content. The conversation control unit 28 controls the conversation between the user and the content providing system 1.

The distribution unit 29 repeatedly executes the processes of steps S109 to S111 until all the selected contents are distributed. According to this embodiment, even when there are a plurality of contents to be output, appropriate contents can be output according to the route.

3. 3. Modifications The present invention is not limited to the above-described embodiment, and various modifications can be performed. Hereinafter, some modification examples will be described. Two or more of the following modifications may be used in combination.

3-1. Modification 1
The reference position for prioritizing content is not limited to the destination. If it is one point on the route, the priority of the content may be determined based on a position other than the destination such as a departure point or a waypoint. For example, when the priority of the content is determined according to the departure place, the destination is read as the departure place in the priority table of FIG. Alternatively, the priority of the content may be determined according to the combination of two or more positions on the route, for example, a starting point and a destination. According to this example, content is prioritized based on more diverse criteria.

3-2. Modification 2
The priority of the content may be determined according to the combination of a plurality of points on the route instead of a single point on the route. For example, the priority of content is determined according to the combination of the origin and destination of the route. In this case, the priority table of FIG. 5 corresponds the combination of the starting point and the destination with the priority of the content. According to this example, content is prioritized based on more diverse criteria than if only a single point was used.

3-3. Modification 3
The method in which the order determination unit 27 determines the order in which the contents are distributed is not limited to the method exemplified in the embodiment. For example, the order determination unit 27 may determine the order according to the priority order without using the order table. Alternatively, the order determination unit 27 may determine the order according to the attributes of the content such as the time required for output, the data size, the update time of the content, the creator of the content, and the like. According to this example, the order in which content is delivered is determined based on more diverse criteria.

3-4. Modification 4
In the above-described embodiment, the order in which the distribution unit 29 distributes the content to the vehicle-mounted device 10 and the order in which the vehicle-mounted device 10 actually outputs the content to the user are the same. However, the order in which the distribution unit 29 distributes the content to the vehicle-mounted device 10 and the order in which the vehicle-mounted device 10 actually outputs the content to the user do not have to be the same. In this case, in addition to the content, the distribution unit 29 outputs information for designating the order or timing of outputting the content to the vehicle-mounted device 10. The vehicle-mounted device 10 outputs the contents to the user in the order specified by this information. According to this example, for example, when the server 20 acquires data of a part of the content from another server device, the content stored by the server 20 is delivered to the vehicle-mounted device 10 first, and the content is arranged according to a flexible schedule. Can be delivered. The word "delivery" in the distribution unit 29 may be read as "output".

3-5. Other Modified Examples The hardware configuration of the content providing system 1 is not limited to the examples described in the embodiments. A part of the functions implemented in the vehicle-mounted device 10 in the embodiment may be implemented in the server 20. Further, a part or all of the functions implemented in the server 20 in the embodiment may be implemented in the vehicle-mounted device 10. As an example, all the functions may be integrated in the vehicle-mounted device 10. In another example, the content providing system 1 may have yet another device in addition to the vehicle-mounted device 10 and the server 20. In this case, some of the functions implemented in the vehicle-mounted device 10 and the server 20 in the embodiment may be implemented in this device. As an example, the voice output unit 12 and the voice input unit 13 may be mounted on this device (for example, a smartphone). In this case, the voice output unit 12 and the voice input unit 13 can be provided for each user by using their own smartphones.

The block diagram used in the description of the above embodiment shows a block of functional units. These functional blocks (components) are realized by any combination of hardware and / or software. Further, the means for realizing each functional block is not particularly limited. That is, each functional block may be realized by one physically and / or logically coupled device, or directly and / or indirectly by two or more physically and / or logically separated devices. (For example, wired and / or wireless) may be connected and realized by these a plurality of devices. In this specification, the word "device" can be read as a circuit, a device, a unit, or the like.

The hardware configuration of the vehicle-mounted device 10 and the server 20 may be configured to include one or more of the devices shown in the figure, or may be configured not to include some of the devices. Further, the in-vehicle device 10 and the server 20 are hardware such as a microprocessor, a digital signal processor (DSP: Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), and an FPGA (Field Programmable Gate Array). May be included, and some or all of each functional block may be realized by the hardware. For example, processor 1001 may be implemented on at least one of these hardware. The program may be transmitted from the network via a telecommunication line.
