It is a flowchart which shows an example of the information processing procedure executed by the output control device 300 of a terminal 82. An example of the computer 2000 is shown.

Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention within the scope of the claims. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 schematically shows a usage scene of a warning sound control system. The sound control system 10 includes a vehicle 20, a terminal 82, and an external device 12. The terminal 82 is a terminal owned by the person 80. The terminal 82 is a mobile terminal such as a mobile phone or a smartphone. The terminal 82 is an example of an “external terminal”. The vehicle 20 is an automobile. The vehicle 20 is an example of a "moving body".

The vehicle 20 includes an information processing device 40 and a sensor 29. The information processing device 40 communicates via the communication network 90. The communication network 90 includes an IP network such as the Internet, a P2P network, a dedicated line including a VPN, a virtual network, a mobile communication network, and the like. The information processing apparatus 40 acquires the warning sound limiting area information indicating the area where the warning sound of the vehicle should be restricted through the communication network 90. In the present embodiment, the area where the warning sound of the vehicle should be restricted is referred to as a "warning sound limiting area". The warning sound restriction area is, for example, an area where the vehicle is prohibited from emitting a warning sound.

The sensor 29 included in the vehicle 20 includes a camera and a radar. The camera included in the sensor 29 captures the surroundings of the vehicle 20 and generates image information. The radar included in the sensor 29 acquires the distance to a surrounding object located in the traveling direction of the vehicle 20 and generates distance information. The information processing device 40 detects the presence of the person 80 based on the image information acquired from the sensor 29. Further, the information processing apparatus 40 acquires the distance information from the vehicle 20 to the person 80 based on the distance information acquired by the radar.

When the information processing device 40 detects the person 80 when the vehicle 20 is traveling in the warning sound limiting area, the information processing apparatus 40 transmits output suppression request information requesting that the voice output of the terminal 82 be suppressed. The output suppression request information includes vehicle speed information of the vehicle 20 and information indicating the distance to the person 80.

When the terminal 82 receives the output suppression request information, the terminal 82 suppresses the output of the audio being played back. For example, when the terminal 82 determines that the vehicle 20 will reach the current position of the terminal 82 within a predetermined time based on the vehicle speed information and the distance information included in the output suppression request information, the voice being played is played. Suppress the output. Specifically, the terminal 82 may suppress the output of the sound being played by lowering the volume of the sound being played. The terminal 82 may suppress the output of audio during reproduction by turning off the noise canceling function. Further, the terminal 82 vibrates the terminal 82 itself to warn the person 80 by vibration. As a result, the person 80 in the warning sound restriction area can easily notice that the vehicle 20 is approaching.

Further, the information processing device 40 prohibits the operation of the warning sound device included in the vehicle 20 when the current position of the vehicle 20 is within the warning sound limiting area. For example, when the information processing device 40 instructs the passenger of the vehicle 20 to sound the warning sound when the current position of the vehicle 20 is within the warning sound limiting area, the information processing device 40 replaces the operation of the warning sound device with the operation of the vehicle 20. Output warning information from surrounding terminals. Specifically, the information processing apparatus 40 transmits warning output request information requesting surrounding terminals to output a warning sound. When the terminal 82 receives the warning output request information, the terminal 82 suppresses the sound being played by the terminal 82 and outputs a warning sound. As a result, the vehicle 20 can warn the person 80 even within the warning sound restriction area.

The information processing device 40 may communicate with the terminal 82 by direct communication. For example, the information processing apparatus 40 may directly communicate with the terminal 82 by short-range direct communication in Cellular-V2X. Short-distance direct communication in Cellular-V2X includes communication methods such as LTE-V2X PC5 and 5G-V2X PC5. As direct communication between the information processing apparatus 40 and the terminal 82, a form using Wi-Fi, DSRC (registered trademark) (Dedicated Short Range Communications) may be adopted. As the direct communication between the information processing apparatus 40 and the terminal 82, any direct communication method such as Bluetooth (registered trademark) may be adopted in addition to Cellular-V2X and DSRC (registered trademark). The information processing apparatus 40 may directly communicate with the terminal 82 by using the communication infrastructure provided in ITS (Intelligent Transport Systems). The information processing apparatus 40 may transmit output suppression request information and warning output request information to the surroundings by broadcasting.

In the present embodiment, the case where the "object" having a risk of approaching the vehicle 20 is a "person" will be mainly described. However, the "object" that is at risk of approaching the vehicle 20 may be another moving object or vehicle. In this case, the "terminal" may be a communication processing device such as a telematics control unit (TCU) included in another vehicle.

FIG. 2 shows the system configuration of the vehicle 20. The vehicle 20 includes a sensor 29, an information processing device 40, a driving support control device 30, a display device 32, a sound alarm device 38, a communication unit 290, and a sound alarm operation unit 50.

The sensor 29 includes a radar 21, a camera 22, a GNSS receiving unit 23, and a vehicle speed sensor 24. The radar 21 may be a LiDAR, a millimeter wave radar, or the like. The camera 22 captures the periphery of the vehicle 20 and generates image information. For example, the camera 22 captures an image of the vehicle 20 in the traveling direction and generates image information. The GNSS receiving unit 23 receives radio waves transmitted from a GNSS (Global Navigation Satellite system) satellite. The GNSS receiving unit 23 generates information indicating the current position of the vehicle 20 based on the signal received from the GNSS satellite. The sensor 29 may include a position sensor such as an odometer and an IMU (inertial measurement unit) such as an acceleration sensor and an attitude sensor.

The driving support control device 30 uses the information detected by the sensor 29 to provide driving support for the vehicle 20. The driving support control device 30 may be realized by an ECU having a function of an advanced driving support system (ADAS; Advanced Driver-Assistance Systems).

The warning device 38 warns the outside of the vehicle 20. The warning sound device 38 is a device that outputs a warning sound as a sound wave. The warning sound operation unit 50 receives an instruction regarding the warning sound from the passenger of the vehicle 20. The first warning sound operation unit 51 receives an instruction from the passenger of the vehicle 20 to output the warning sound to the warning sound device 38. The second warning sound operation unit 52 receives an instruction to transmit the warning output request information from the passenger of the vehicle 20. The first warning sound operation unit 51 and the second warning sound operation unit 52 include members such as buttons and switches that receive user operations by the passengers of the vehicle 20, respectively.

The information processing device 40 includes a processing unit 200 and a storage unit 280. The processing unit 200 is realized by, for example, an arithmetic processing device including a processor. The storage unit 280 is realized by including a non-volatile storage medium. At least a part of the processing unit 200 and the storage unit 280 may be realized by an ECU (Electronic Control Unit) including a microcomputer equipped with a CPU, ROM, RAM, I / O, a bus, and the like. The processing unit 200 performs processing using the information stored in the storage unit 280. The communication unit 290 is responsible for communication with the external device 12 and communication with the communication terminal 82. The communication unit 290 may be realized by a TCU (Telematics Control Unit).

The processing unit 200 includes an image acquisition unit 210, an acquisition unit 220, a position information acquisition unit 230, a detection unit 212, a position identification unit 214, a determination unit 240, a sound alarm device control unit 250, and a communication control unit. It is equipped with 270.

The image acquisition unit 210 acquires an image of the outside of the vehicle 20. Specifically, the image acquisition unit 210 acquires image information from the camera 22. The communication control unit 270 controls the communication unit 290 that communicates with the terminals 82 around the vehicle 20.

The sound alarm device control unit 250 controls the sound alarm device 38. The alarm sound device control unit 250 controls the alarm sound device 38 based on the operation on the alarm sound operation unit 50. For example, the warning sound device control unit 250 outputs a warning sound from the warning sound device 38 when the first warning sound operation unit 51 is operated.

The acquisition unit 220 acquires area information regarding an area that limits the output of the sound alarm device 38. Specifically, the acquisition unit 220 acquires the warning sound restriction area information. The acquisition unit 220 acquires the warning sound restriction area information transmitted from the external device 12. The position information acquisition unit 230 acquires the position information of the vehicle 20. Specifically, the position information acquisition unit 230 acquires the position information of the vehicle 20 from the GNSS receiving unit 23. The determination unit 240 determines whether or not the position indicated by the position information acquired by the position information acquisition unit 230 is within the area indicated by the area information acquired by the acquisition unit 220.

The sound alarm device control unit 250 limits the output of the sound alarm device 38 based on the area information acquired by the acquisition unit 220 and the position information acquired by the position information acquisition unit 230. The communication control unit 270 requests the terminal 82 to control the output unit included in the terminal 82 based on the area information acquired by the acquisition unit 220 and the position information acquired by the position information acquisition unit 230. For example, when the position of the vehicle 20 is within the area indicated by the area information, the sound alarm device control unit 250 prohibits the output of the sound alarm device 38, and the communication control unit 270 controls the output unit provided in the terminal 82. The request information to be requested is transmitted to the communication unit 290. The "output unit included in the terminal 82" corresponds to the "output unit 330" described later in relation to FIG. 3 and the like.

As an example, the communication control unit 270 may request the output unit 330 included in the terminal 82 to output a warning sound. The communication control unit 270 may request a decrease in the volume output by the output unit 330. The communication control unit 270 may request a decrease in the noise canceling strength of the output unit 330. The communication control unit 270 may request the output unit 330 to output vibration. The communication control unit 270 may request the output unit 330 to display. The communication control unit 270 may increase the strength of the demand for the output unit 330 as the speed of the vehicle 20 increases.

The detection unit 212 detects an object that is predicted to approach the vehicle 20. The detection unit 212 extracts an object predicted to approach the vehicle 20 from the image information acquired by the image acquisition unit 210. For example, the detection unit 212 extracts an object predicted to approach the vehicle 20 by recognizing the image information acquired by the image acquisition unit 210. In this embodiment, the case where the "object predicted to approach the vehicle 20" is a person will be described.

The position specifying unit 214 identifies the position of the target that is predicted to approach the vehicle 20. The position specifying unit 214 identifies the position of the target detected by the detection unit 212. The position specifying unit 214 may specify the distance to an object located in the direction in which the target detected by the detection unit 212 exists, based on the distance information acquired by the radar 21. The shorter the distance to the position specified by the position specifying unit 214, the higher the intensity of at least one of the requests for the output unit 330 of the communication control unit 270.

The communication control unit 270 causes the communication unit 290 to transmit request information including a range determined from the position specified by the position specifying unit 214, and controls the output unit 330 when the terminal 82 is located within the range. You may request it. For example, the communication control unit 270 may transmit request information including a predetermined range including the position specified by the position specifying unit 214 from the communication unit 290.

The storage unit 280 stores the position information that should suppress the request to the terminal 82. For example, the "position information for suppressing the request to the terminal 82" may be, for example, the home position information of the occupant of the vehicle 20. The sound alarm device control unit 250 determines whether or not to suppress the request to the terminal 82 based on the position information acquired by the position information acquisition unit 230 and the position information stored in the storage unit 280. For example, when the sound alarm device control unit 250 is within a predetermined range including the position indicated by the position information stored in the storage unit 280, the position indicated by the position information acquired by the position information acquisition unit 230 is within a predetermined range. It may be determined that the request to the terminal 82 is suppressed. Thereby, for example, when the vehicle 20 is located near the home, it is possible to suppress the control of the output of the terminal in the home. The communication control unit 270 may make a request to the output unit 330 on condition that the detection unit 212 detects an object that is predicted to approach the vehicle 20. Thereby, for example, when there is no person in front of the vehicle 20, it is possible to suppress the control of the output of the terminal existing around the vehicle 20.

The communication unit 290 may transmit the request information to the terminal 82 by direct communication. The communication unit 290 may broadcast the request information. The communication unit 290 may transmit the request information by directional communication. For example, the communication unit 290 may have a directional antenna and transmit request information toward a position specified by the position specifying unit 214.

FIG. 3 shows the system configuration of the terminal 82. The terminal 82 includes an output control device 300, a storage unit 380, a communication unit 290, an output unit 330, and a GNSS receiving unit 323.

The output control device 300 performs processing using the information stored in the storage unit 380. The communication unit 390 is responsible for communication with the outside including the information processing device 40.

The GNSS receiving unit 23 receives radio waves transmitted from the GNSS satellite. The GNSS receiving unit 23 generates position information indicating the current position of the terminal 82 based on the signal received from the GNSS satellite. The position information acquisition unit 310 acquires position information from the GNSS receiving unit 323.

The vibrating unit 337 may include, for example, a vibration motor that vibrates the terminal 82. The voice output unit 338 outputs voice as a sound wave. The audio output unit 338 may include a speaker. The audio output unit 338 may include an internal speaker built in the terminal 82. The audio output unit 338 may include an external speaker connected to the terminal 82. The external speaker may be a speaker included in the earphone. The audio output unit 338 may have a noise canceling function.

The communication control unit 370 controls the communication unit 390. The output control unit 350 controls the output unit 330. When the output control unit 350 receives request information requesting control of the output unit 330 from the vehicle 20 to the terminal 82 by the communication unit 390, the output control unit 350 is at least one of audio output, display output, and vibration from the output unit 330.

The request information may include request information for requesting a decrease in the noise canceling strength included in the output unit 330.

The request information may include speed information indicating the speed of the vehicle 20. The output control unit 350 may increase the output control amount as the speed indicated by the speed information increases. For example, the output control unit 350 may increase the volume of the warning sound to the output unit 330 as the speed indicated by the speed information increases. The output control unit 350 may increase the amount of decrease in volume as the speed indicated by the speed information increases. The output control unit 350 may increase the strength of the noise canceling function as the speed indicated by the speed information increases.

The request information may include distance information indicating the distance to the vehicle 20. The output control unit 350 may increase the output control amount as the distance indicated by the distance information is shorter. For example, the output control unit 350 may increase the volume of the warning sound to the output unit 330 as the distance indicated by the distance information becomes shorter. The output control unit 350 may increase the amount of decrease in volume as the distance indicated by the distance information is shorter. The output control unit 350 may increase the strength of the noise canceling function as the distance indicated by the distance information is shorter.

The request information may include information indicating the time until the vehicle 20 approaches the position of the terminal. The output control unit 350 may increase the output control amount as the time until the vehicle 20 approaches the position of the terminal is shorter. For example, the output control unit 350 may increase the volume of the warning sound to the output unit 330 as the time until the vehicle 20 approaches the position of the terminal is shorter. The output control unit 350 may increase the amount of decrease in volume as the time until the vehicle 20 approaches the position of the terminal is shorter. The output control unit 350 may increase the strength of the noise canceling function as the time until the vehicle 20 approaches the position of the terminal is shorter.

The request information may include range information indicating a range in which a terminal for which output control should be performed exists. The output control unit 350 may control the output of the output unit 330 when the terminal is located within the range indicated by the range information included in the request information. For example, the output control unit 350 may control the output of the output unit 330 when the position indicated by the position information acquired by the position information acquisition unit 310 is within the range indicated by the range information included in the request information.

FIG. 4 schematically shows a processing sequence in the vehicle 20 and the terminal 82. FIG. 4 is a processing sequence when the vehicle 20 is traveling in the warning sound restriction region. In S310, the detection unit 212 detects the person 80 by image recognition using the image information acquired by the image acquisition unit 210. In S312, the communication control unit 270 transmits the output suppression request information. The output suppression request information includes identification information of the vehicle 20, vehicle speed of the vehicle 20, distance to the person 80 detected by S310, and range information indicating a range in which output suppression should be performed. The range information may include information indicating a range of a predetermined range including the position of the person 80 detected in S310. The range information may include coordinate information representing the boundary of the area including the position of the person 80. The range information may include center coordinates and radius information representing the outer shape of a circular region centered on the position of the person 80. The information indicating the vehicle speed of the vehicle 20 and the distance to the person included in the output suppression request information is an example of the information indicating the time until the vehicle 20 approaches the position of the terminal.

In S320, the output control unit 350 determines whether or not to suppress the audio output. For example, the output control unit 350 calculates the time until the vehicle 20 approaches the position of the terminal based on the information included in the output suppression request information, and the calculated time is shorter than the predetermined time. , It may be determined that the output is suppressed. The output control unit 350 may calculate the time until the vehicle 20 approaches the position of the terminal by dividing the distance to the person 80 by the vehicle speed of the vehicle 20.

When the output control unit 350 determines that the output is suppressed, the output control unit 350 suppresses the output in S322. For example, the output control unit 350 lowers the volume of the sound being reproduced by the sound output unit 338. As an example, the output control unit 350 reduces the volume of the sound being reproduced by the sound output unit 338 by 50%. Further, the output control unit 350 reduces the strength of the noise canceling function of the voice output unit 338. For example, the output control unit 350 stops the operation of the noise canceling function of the voice output unit 338. This makes it easier for the person 80 to hear the sound generated by the vehicle 20 when the vehicle 20 may be in close proximity. The output control unit 350 may increase the amount of decrease in the volume of the sound reproduced by the sound output unit 338 according to the short time until the vehicle 20 approaches the position of the terminal. Further, the output control unit 350 may increase the amount of decrease in the strength of the noise canceling function of the voice output unit 338 according to the short time until the vehicle 20 approaches the position of the terminal.

In the vehicle 20, when the second warning sound operation unit 52 is operated in S314, the communication control unit 270 transmits warning output request information. The warning output request information includes the identification information of the vehicle 20, the vehicle speed of the vehicle 20, the distance to the person 80 detected by S310, and the range information indicating the range in which the warning information should be output. The range information may include information indicating a range of a predetermined range including the position of the person 80 detected in S310. The range information may include coordinate information representing the boundary of the area including the position of the person 80. The range information may include center coordinates and radius information representing the outer shape of a circular region centered on the position of the person 80.

In S324, when the output control unit 350 of the terminal 82 receives the warning output request information, the output control unit 330 causes the output unit 330 to output the warning information. For example, the output control unit 350 generates a warning sound from the voice output unit 338. The output control unit 350 may display a predetermined warning information on the display unit 332. The output control unit 350 may vibrate the vibration unit 337 in a predetermined pattern. As a result, when the vehicle 20 is located within the warning sound restriction area, it is possible to warn the person around the vehicle 20.

In S324, when the output control unit 350 generates a warning sound from the voice output unit 338, the volume of the sound being played is reduced by 50% and a warning sound is given at a volume higher than the volume of the sound being played.
