[System configuration]
(overall structure)
FIG. 1 is a diagram illustrating a configuration example of an audio output system according to an embodiment. A voice output system 1 according to this embodiment includes a voice output device 100 and a server device 200 . The audio output device 100 is mounted on the vehicle Ve. The server device 200 communicates with a plurality of audio output devices 100 mounted on a plurality of vehicles Ve.

The voice output device 100 basically performs route search processing, route guidance processing, and the like for the user who is a passenger of the vehicle Ve. For example, when a destination or the like is input by the user, the voice output device 100 transmits an upload signal S1 including position information of the vehicle Ve and information on the designated destination to the server device 200 . Server device 200 calculates the route to the destination by referring to the map data, and transmits control signal S2 indicating the route to the destination to audio output device 100 . The voice output device 100 provides route guidance to the user by voice output based on the received control signal S2.

In addition, the voice output device 100 provides various information to the user through interaction with the user. For example, when a user makes an information request, the audio output device 100 supplies the server device 200 with an upload signal S1 including information indicating the content or type of the information request and information about the running state of the vehicle Ve. The server device 200 acquires and generates information requested by the user, and transmits it to the audio output device 100 as a control signal S2. The audio output device 100 provides the received information to the user by audio output.

(Voice output device)
The voice output device 100 moves together with the vehicle Ve and performs route guidance mainly by voice so that the vehicle Ve travels along the guidance route. It should be noted that "route guidance based mainly on voice" refers to route guidance in which the user can grasp information necessary for driving the vehicle Ve along the guidance route at least from only voice, and the voice output device 100 indicates the current position. It does not exclude the auxiliary display of a surrounding map or the like. In this embodiment, the voice output device 100 outputs at least various information related to driving, such as points on the route that require guidance (also referred to as “guidance points”), by voice. Here, the guidance point corresponds to, for example, an intersection at which the vehicle Ve turns right or left, or other passing points important for the vehicle Ve to travel along the guidance route. The voice output device 100 provides voice guidance regarding guidance points such as, for example, the distance from the vehicle Ve to the next guidance point and the traveling direction at the guidance point. Hereinafter, the voice regarding the guidance for the guidance route is also referred to as "route voice guidance".

The audio output device 100 is attached, for example, above the windshield of the vehicle Ve or on the dashboard. Note that the audio output device 100 may be incorporated in the vehicle Ve.

FIG. 2 is a block diagram showing a schematic configuration of the audio output device 100. As shown in FIG. The audio output device 100 mainly includes a communication unit 111, a storage unit 112, an input unit 113, a control unit 114, a sensor group 115, a display unit 116, a microphone 117, a speaker 118, and an exterior camera 119. and an in-vehicle camera 120 . Each element in the audio output device 100 is interconnected via a bus line 110 .

The communication unit 111 performs data communication with the server device 200 under the control of the control unit 114 . The communication unit 111 may receive, for example, map data for updating a map DB (DataBase) 4 to be described later from the server device 200 .

The storage unit 112 is composed of various memories such as RAM (Random Access Memory), ROM (Read Only Memory), non-volatile memory (including hard disk drive, flash memory, etc.). The storage unit 112 stores a program for the audio output device 100 to execute predetermined processing. The above programs may include an application program for providing route guidance by voice, an application program for playing back music, an application program for outputting content other than music (such as television), and the like. Storage unit 112 is also used as a working memory for control unit 114 . Note that the program executed by the audio output device 100 may be stored in a storage medium other than the storage unit 112 .

The storage unit 112 also stores a map database (hereinafter the database is referred to as “DB”) 4 . Various data required for route guidance are recorded in the map DB 4 . The map DB 4 stores, for example, road data representing a road network by a combination of nodes and links, and facility data indicating facilities that are candidates for destinations, stop-off points, or landmarks. The map DB 4 may be updated based on the map information received by the communication section 111 from the map management server under the control of the control section 114 .

The input unit 113 is a button, touch panel, remote controller, or the like for user operation. The display unit 116 is a display or the like that displays based on the control of the control unit 114 . The microphone 117 collects sounds inside the vehicle Ve, particularly the driver's utterances. A speaker 118 outputs audio for route guidance to the driver or the like.

Sensor group 115 includes external sensor 121 and internal sensor 122 . The external sensor 121 is, for example, one or more sensors for recognizing the surrounding environment of the vehicle Ve, such as a lidar, radar, ultrasonic sensor, infrared sensor, and sonar. The internal sensor 122 is a sensor that performs positioning of the vehicle Ve, and is, for example, a GNSS (Global Navigation Satellite System) receiver, a gyro sensor, an IMU (Inertial Measurement Unit), a vehicle speed sensor, or a combination thereof. It should be noted that the sensor group 115 may have a sensor that allows the control unit 114 to directly or indirectly derive the position of the vehicle Ve from the output of the sensor group 115 (that is, by performing estimation processing).

The vehicle exterior camera 119 is a camera that captures the exterior of the vehicle Ve. The exterior camera 119 may be only a front camera that captures the front of the vehicle, or may include a rear camera that captures the rear of the vehicle in addition to the front camera. good too. On the other hand, the in-vehicle camera 120 is a camera for photographing the interior of the vehicle Ve, and is provided at a position capable of photographing at least the vicinity of the driver's seat.

The control unit 114 includes a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc., and controls the entire audio output device 100 . For example, the control unit 114 estimates the position (including the traveling direction) of the vehicle Ve based on the outputs of one or more sensors in the sensor group 115 . Further, when a destination is specified by the input unit 113 or the microphone 117, the control unit 114 generates route information indicating a guidance route to the destination, Based on the positional information and the map DB 4, route guidance is provided. In this case, the control unit 114 causes the speaker 118 to output route voice guidance. Further, the control unit 114 controls the display unit 116 to display information about the music being played, video content, a map of the vicinity of the current position, or the like.

Note that the processing executed by the control unit 114 is not limited to being realized by software based on a program, and may be realized by any combination of hardware, firmware, and software. Also, the processing executed by the control unit 114 may be implemented using a user-programmable integrated circuit such as an FPGA (field-programmable gate array) or a microcomputer. In this case, this integrated circuit may be used to implement the program executed by the control unit 114 in this embodiment. Thus, the control unit 114 may be realized by hardware other than the processor.

The configuration of the audio output device 100 shown in FIG. 2 is an example, and various modifications may be made to the configuration shown in FIG. For example, instead of storing the map DB 4 in the storage unit 12 , the control unit 114 may receive information necessary for route guidance from the server device 200 via the communication unit 111 . In another example, instead of including the speaker 118, the audio output device 100 is electrically connected to an audio output unit configured separately from the audio output device 100, or by a known communication means, so as to output the audio. Audio may be output from the output unit. In this case, the audio output unit may be a speaker provided in the vehicle Ve. In still another example, the audio output device 100 does not have to include the display section 116 . In this case, the audio output device 100 does not need to perform display-related control at all. may be executed. Similarly, instead of including the sensor group 115, the audio output device 100 may acquire information output by sensors installed in the vehicle Ve based on a communication protocol such as CAN (Controller Area Network) from the vehicle Ve. .

(Server device)
The server device 200 generates route information indicating a guidance route that the vehicle Ve should travel based on the upload signal S1 including the destination and the like received from the voice output device 100 . The server device 200 then generates a control signal S2 relating to information output in response to the user's information request based on the user's information request indicated by the upload signal S1 transmitted by the audio output device 100 and the running state of the vehicle Ve. The server device 200 then transmits the generated control signal S<b>2 to the audio output device 100 .

Further, the server device 200 generates content for providing information to the user of the vehicle Ve and for interacting with the user, and transmits the content to the audio output device 100 . The information provided to the user is mainly that the vehicle Ve has entered a predetermined driving situation, or that an image of the surroundings of the vehicle Ve taken from the vehicle Ve (an image of the surroundings of the vehicle Ve) includes a characteristic subject. This is a push-type information provision that is started from the server device 200 side triggered by the presence of the information. Also, the dialog with the user is basically a pull-type dialog that starts with a question or inquiry from the user. However, interaction with the user may start with push-type content provision.

FIG. 3 is a diagram showing an example of a schematic configuration of the server device 200. As shown in FIG. The server device 200 mainly has a communication section 211 , a storage section 212 and a control section 214 . Each element in the server device 200 is interconnected via a bus line 210 .

The communication unit 211 performs data communication with an external device such as the audio output device 100 under the control of the control unit 214 . The storage unit 212 is composed of various types of memory such as RAM, ROM, nonvolatile memory (including hard disk drive, flash memory, etc.).

The control unit 214 includes a CPU, a GPU, etc., and controls the entire server device 200 . Further, the control unit 214 operates together with the audio output device 100 by executing a program stored in the storage unit 212, and executes route guidance processing, information provision processing, and the like for the user. For example, based on the upload signal S1 received from the audio output device 100 via the communication unit 211, the control unit 214 generates route information indicating a guidance route or a control signal S2 relating to information output in response to a user's information request. Then, the control unit 214 transmits the generated control signal S2 to the audio output device 100 through the communication unit 211.

[Push-type content provision]
Next, push-type content provision will be described. The provision of push-type content means that the audio output device 100 outputs audio content corresponding to the driving situation to the user based on the image around the vehicle Ve and the driving situation of the vehicle Ve. . Specifically, the audio output device 100 acquires an image of the surroundings of the vehicle Ve captured by the exterior camera 119 and driving situation information indicating the driving situation of the vehicle Ve, and transmits the acquired information to the server device 200 . When the image received from the voice output device 100 mounted on the vehicle Ve includes a characteristic subject, the server device 200 provides guidance according to the driving situation information received from the voice output device 100 based on the image. A script is generated and transmitted to the audio output device 100 . The audio output device 100 audio-outputs the content for output received from the server device 200 . In this way, the content corresponding to the image around the vehicle Ve and the driving situation of the vehicle Ve is output to the user by voice.

The image around the vehicle Ve may be either a still image or a moving image. In addition, the image of the surroundings of the vehicle Ve may be an image taken in response to an instruction from the passenger of the vehicle Ve, or an image automatically captured by the passenger during driving of the vehicle Ve. It may also be an image that has been taken (without instructions).

The driving situation information includes position information, which is information related to the position of the vehicle Ve when the image around the vehicle Ve was captured, time information, which is information related to the time when the image was captured, and At least one of shooting direction information, which is information relating to the shooting direction when the image was shot, is included. The driving status information can be acquired based on the functions of each part of the voice output device 100, such as traffic information (including speed regulation and traffic congestion information) around the position of the vehicle Ve and the destination. at least one piece of information may be further included. In addition, the driving situation information may further include either the voice (excluding the user's speech) obtained by the microphone 117 or the image captured by the in-vehicle camera 120 . Also, the driving status information may further include information received from the server device 200 through the communication unit 111 .

The shooting direction information may include information indicating the direction corresponding to the orientation of the exterior camera 119, such as the traveling direction of the vehicle Ve, the lateral direction of the vehicle Ve, and the rearward direction of the vehicle Ve. can. The shooting direction information can also include information indicating the direction of the vehicle Ve. The shooting direction information can also include information indicating the direction within the angle of view of the exterior camera 119, such as the front of the vehicle Ve, the front right of the vehicle Ve, the front left of the vehicle Ve, and the like.

[Concrete example of method for generating guidance contents]
In this embodiment, for example, landmarks such as Tokyo Tower, Mt. Fuji, and rows of cherry trees can be set as characteristic subjects included in the image around the vehicle Ve. The control unit 214 of the server device 200 analyzes the image transmitted from the audio output device 100 and detects a characteristic subject included in the image. For example, the control unit 214 can perform object recognition using AI (Artificial Intelligence) and extract a characteristic object included in the image as a characteristic subject.

Note that the control unit 214 may specify a characteristic subject using the driving situation information in addition to the analysis result of the image. For example, when the control unit 214 detects that a tower is shown in the image by analyzing the image, and determines that the vehicle Ve is near Tokyo Tower based on the position information included in the driving situation information, The tower can be identified as Tokyo Tower. Further, the control unit 214 detects that a mountain is reflected in the image by analyzing the image, and determines that the image is an image taken in the direction of Mt. Fuji based on the shooting direction information of the driving situation information. In this case, the mountain can be identified as Mt.Fuji.

For example, when the image around the vehicle Ve includes Tokyo Tower and a group of buildings, and the shooting direction information included in the driving situation information received from the vehicle Ve indicates the front of the vehicle Ve, Based on the image, the server device 200 generates a script SC11 for providing guidance according to the shooting direction information, "Tokyo Tower can be seen in front from between buildings." Then, the server device 200 transmits the script SC11 to the audio output device 100 as guidance content. Thus, the script SC11 is audibly output to the user.

According to this embodiment, for example, the image around the vehicle Ve does not include Tokyo Tower, the image includes a group of buildings, and the driving situation information received from the vehicle Ve includes If the included location information indicates a location in the vicinity of Tokyo Tower, the server device 200 can generate a script saying, "You can't see Tokyo Tower from this location, can you?"

For example, an image of the surroundings of a vehicle Ve includes Mt. Fuji, the position information included in the driving situation information received from the vehicle Ve indicates a position within an area where Mt. When the photographing direction information included in the driving situation information indicates the front of the vehicle Ve, the server apparatus 200 executes a script SC12 for providing guidance according to the position information and the photographing direction information based on the image. , "Mt. Fuji can be seen in front of you." is generated. Then, the server device 200 transmits the script SC12 to the audio output device 100 as guidance content. Thus, the script SC12 is audibly output to the user.

For example, if the image around the vehicle Ve includes rows of cherry blossom trees before blooming and the time information included in the driving status information received from the vehicle Ve indicates a month other than April, the server Based on the image, the device 200 generates a script SC13 for providing guidance in accordance with the time information, "Cherry blossoms will be in full bloom on this road in April." Then, the server device 200 transmits the script SC13 to the audio output device 100 as guidance content. Thus, the script SC13 is voice-output to the user.

(processing flow)
FIG. 4 is a flow chart for explaining the processing performed in the server device.

First, the control unit 114 acquires an image of the surroundings of the vehicle Ve photographed by the exterior camera 119 and transmits the image to the server device 200 . The server device 200 acquires the image transmitted from the audio output device 100 (step S11).

Next, the control unit 114 acquires driving situation information, which is information related to the driving situation of the vehicle Ve when the image was acquired in step S<b>11 , and transmits the information to the server device 200 . The server device 200 acquires the driving situation information transmitted from the voice output device 100 (step S12).

The control unit 214 analyzes the image acquired in step S11 to determine whether or not the image includes a characteristic subject (step S13).

When the control unit 214 determines that the image acquired in step S11 does not include a characteristic subject (step S13: NO), the processing ends without performing the processing after step S14.

When the control unit 214 determines that the image acquired in step S11 includes a characteristic subject (step S13: YES), the control unit 214 determines the driving situation information acquired in step S12 based on the image. A script for guidance is generated (step S14).

Next, the control unit 214 performs processing for storing generated content information, which is information related to the script generated in step S14, in the storage unit 212 (step S15).

The generated content information described above includes the script generated in step S14, the driving situation information used when generating the script, and the image acquired together with the driving situation information. That is, according to the process of step S15, the generated guidance content corresponding to the script generated in step S14, the driving situation information used when generating the generated guidance content, and the driving situation information The information associated with the image acquired together with the image is stored in the storage unit 212 as generated content information.

Next, the control unit 214 acquires the script generated in step S14 as guidance content, and transmits the acquired guidance content to the audio output device 100 (step S16). Thus, the generation of content by the server device 200 ends. The audio output device 100 audio-outputs the content received from the server device 200 to passengers of the vehicle Ve.

According to this embodiment, the server device 200 functions as a content generation device, and the control unit 214 functions as an information acquisition unit and a content generation unit.

Incidentally, in the present embodiment, at least a part of the processes in FIG. 4 may be performed by the control unit 114.

That is, according to this embodiment, the audio output device 100 may function as a content generation device, and the control unit 114 may function as an information acquisition unit and a content generation unit. good.

As described above, according to the present embodiment, when a characteristic subject is included in an image, based on the image, the driving condition, which is the information related to the driving situation of the vehicle when the image was obtained, is obtained. It is possible to generate guidance content for providing guidance according to situation information. Therefore, according to the present embodiment, it is possible to output content that considers the viewpoint of the passenger as content for providing guidance to the passenger of the vehicle.

(Modification)
Modifications of the above embodiment will be described below. FIG. 5 is a diagram for explaining a modification of the processing performed in the server device.

According to the modified example, instead of the script generation processing shown in step S14, for example, the generated script included in the generated content information stored in the storage unit 212 is used to generate the driving of the vehicle Ve. A process for acquiring a script according to the situation information may be performed. A specific example of such processing will be described below.

By referring to the generated content information stored in the storage unit 212, the control unit 214 determines whether or not there is a generated script corresponding to the driving situation information obtained in step S12 (step S21). ).

If the control unit 214 determines that there is no generated script corresponding to the driving situation information obtained in step S12 (step S21: NO), it performs the process of step S13. If the control unit 214 determines that there is a generated script corresponding to the driving situation information obtained in step S12 (step S21: YES), it acquires the generated script (step S22). After that, the process of step S16 is performed.

Specifically, the control unit 214 determines whether the image obtained in step S11 is included in the generated content information based on the position information and the shooting direction information included in the driving situation information obtained in step S12. It is detected whether or not the image was captured in the same shooting situation as the image in (for example, the same shooting position and the same shooting direction). Then, if the control unit 214 detects that the image obtained in step S11 was not shot in the same shooting conditions as the other images included in the generated content information, in step S12 It is determined that there is no generated script corresponding to the obtained driving situation information, and the process of step S13 is performed. If the control unit 214 detects that the image obtained in step S11 was shot in the same shooting conditions as the other images included in the generated content information, the control unit 214 After determining that there is a generated script corresponding to the received driving situation information and obtaining the generated script, the process of step S16 is performed.

According to the process according to the modified example described above, when it is detected that the image around the vehicle Ve was shot in the same situation as other images, instead of the process for generating the guidance content, Then, a process is performed to acquire the content that has already been generated as the guidance content. Therefore, according to the process according to the modification described above, for example, the load on the server device 200 caused by the process related to script generation can be reduced.
