Specifically, the time scene before the user uses the vehicle, the time scene after the user uses the vehicle during the user uses the vehicle, and the space scene of the driver, the copilot, the rear passenger, the vehicle-outside related person or object may be included.
Compared with the prior instruction type interaction, the human-computer interaction in the intelligent cabin can be combined with the use scenes of vehicles and users, and the intelligent effect which is more accordant with the user requirements is realized based on image recognition, voice recognition, environment perception and other basic technologies.
The embodiment of the invention identifies the content type of the received sound playing request; searching a target user in the intelligent cabin according to the content type; and directionally playing the sound corresponding to the sound playing request aiming at the target user. Therefore, a target user needing to listen to the sound of the content type can be searched according to the content type of the sound playing request, and the sound corresponding to the sound playing request is played in a directional mode aiming at the target user, so that the target user can receive the sound needing to be listened to by the target user, the sound of other types of the sound needing to be listened to by the target user is not interfered, and good sound listening experience is provided for the user.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for controlling sound output of a smart cabin of a vehicle according to the embodiment of the present invention is shown, and specifically may include the following steps:
step 102, identifying the content type of the received sound playing request;
in the embodiment of the invention, the intelligent cabin can receive a sound playing request. The sound playing request can come from at least one application program in the control system in the intelligent cabin, such as a music playing program, a navigation program and the like. The sound playing request may also come from an electronic device communicatively connected to the smart car, such as a smart phone, a smart watch, a notebook computer, and the like.
In the embodiment of the present invention, the sound playing request may correspond to a content type. For sound playing requests of different content types, users who need to listen to the sound corresponding to the sound playing request may be different. Therefore, after the sound playing request is received, the content type corresponding to the received sound playing request can be identified, so that the user needing to listen to the sound corresponding to the sound playing request can be determined according to the content type.
The content type may be a type of the sound content corresponding to the sound playing request. The content type may be divided according to actual needs based on the purpose of listening to the sound by the user, the priority of the sound, and the like, which is not limited in the present invention. For example, it may be classified into a call type, a driving-related type, an entertainment-related type, and the like, based on the purpose of the user to listen to the sound. It is also possible to classify the sound into high priority, medium priority, low priority, etc. based on the priority of the sound. It may also be classified into a child type, a teenager type, an adult type, etc. based on the type of user listening to the sound.
In a specific implementation, the sound playing request may record information related to the content type, for example, the sound playing request may record a source of the sound playing request; sound attribute information corresponding to the sound playing request, such as a sound author, a sound name, and the like, may also be described. The content type of the received sound play request may be identified using information associated with the content type. For example, the content type of the received sound playing request is identified according to the source application type of the sound playing request, and the content type of the received sound playing request is identified according to information such as a sound author and a sound name of the sound corresponding to the sound playing request.
104, searching a target user in the intelligent cabin according to the content type;
in the embodiment of the invention, the content types of the sounds required to be listened to by different users are different. Therefore, the target users needing to listen to the content type can be determined according to the content type, and the target users can be searched in the intelligent cockpit.
In a specific implementation, a target user who needs to listen to the content type may be determined, and thereafter, the target user in the intelligent cabin may be found by identifying biometric information of the user. The biometric information may include face feature information, voice feature information, fingerprint feature information, and the like, which is not limited in the present invention.
And 106, directionally playing the sound corresponding to the sound playing request aiming at the target user.
In the embodiment of the present invention, the target user may directionally play the sound corresponding to the sound playing request, so that the target user may hear the sound corresponding to the sound playing request, and other users other than the target user may not hear or may not clearly hear the sound corresponding to the sound playing request. Therefore, the target user can hear the sound that the target user wants to hear without generating obvious interference to other users to hear other sounds, and therefore a good sound listening experience can be provided for the users in the intelligent cabin.
In a specific implementation, a plurality of speakers may be disposed in the intelligent cabin, and the plurality of speakers may be disposed at different positions in the intelligent cabin, for example, positions of a cabin top, a cabin bottom, a cabin side, a cabin front, a cabin rear, a seat back, a seat bottom, a console, and the like in the intelligent cabin, which is not limited in this respect. Therefore, the loudspeakers arranged at different positions can be respectively pointed to different users. A user to whom the speaker is pointed may hear the speaker playing content more easily, while a user to whom the speaker is not pointed may hear less easily or cannot hear the speaker playing content.
Therefore, after the target user in the intelligent cabin is found, the target user can adopt at least one loudspeaker which is easy for the target user to hear the playing content, and directionally play the sound corresponding to the sound playing request, so that the target user can hear the sound corresponding to the sound playing request without interfering other users with listening to other sounds.
In one embodiment of the invention, the method further comprises:
s11, when detecting that a new user enters the intelligent cabin, configuring the corresponding relation between the user and the content type for the user in the sound playing configuration information according to the position of the user in the intelligent cabin and the identity information of the user.
In the embodiment of the present invention, when it is detected that a new user enters the intelligent cabin, in order to receive a sound playing request, a sound listening experience for preference may be provided for the user, and a correspondence between the user and the content type may be configured for the user in the sound playing configuration information according to a location of the user in the intelligent cabin and identity information of the user.
In a specific implementation, the location of the user in the smart car may be linked to the type of content the user wishes to hear. For example, in the case where the user is in the main driving position, the user may wish to hear the content associated with the presence of the driving vehicle, and in the case where the user is in the rear position, the user may wish to hear the content associated with the presence of entertainment such as music, games, and the like, instead of hearing the content associated with the presence of the driving vehicle. The identity information of the user may also be linked to the type of content the user wishes to hear. For example, the pre-stored user preferences can be obtained according to the identity information, so that the content types preferred by the user can be known. For example, information such as the age, sex, and place of daily use of the user can be obtained from the identity information of the user, and the content type preferred by the user can be estimated. Therefore, the corresponding relation between the user and the content type can be determined according to the position of the user in the intelligent cabin and the identity information of the user, and the corresponding relation between the user and the content type is recorded in the sound playing configuration information.
By the sound output control method of the intelligent vehicle cabin, the content type of the received sound playing request is identified; searching a target user in the intelligent cabin according to the content type; and directionally playing the sound corresponding to the sound playing request aiming at the target user. The target user can listen to the sound corresponding to the sound playing request, and meanwhile, no obvious interference is generated when other users listen to other sounds, so that good sound listening experience can be provided for the users in the intelligent cabin.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of a method for controlling sound output of a smart cabin of a vehicle according to the embodiment of the present invention is shown, and specifically may include the following steps:
step 202, identifying the content type of the sound playing request according to the received source information and/or sound attribute information of the sound playing request;
in the embodiment of the invention, the intelligent cabin can receive a sound playing request. The sound playing request can come from at least one application program in the control system in the intelligent cabin, such as a music playing program, a navigation program and the like. The sound playing request may also come from an electronic device communicatively connected to the smart car, such as a smart phone, a smart watch, a notebook computer, and the like.
In the embodiment of the present invention, the sound playing request may record source information of a sound, and/or sound attribute information. The source information may record source location information from which the sound may be obtained, for example, the source information may record source application information, source device information, and the like of the sound. The sound attribute information may be recorded with information related to the sound attribute, such as a sound author, a sound name, and the like.
In the embodiment of the present invention, the source information and/or the sound attribute information recorded in the sound playing request may generally reflect the content type of the sound to a certain extent. Therefore, the content type of the received sound playing request can be identified according to the source information of the sound playing request and/or the sound attribute information.
In a specific implementation, the source information recorded in the sound playing request may generally belong to a content category. For example, the source information describes a source application of the sound playing request, and the application program may generally belong to various content categories such as a navigation application, a communication application, a game application, a music application, and the like. For another example, the source information is recorded with a source device of the voice playing request, and the electronic device may have a specific function, for example, a car recorder may be used to record images during the driving of the vehicle, a call watch may be used for calling, and a camera may be used to capture images. The specific functions that the electronic device has may also belong to a certain content category. Therefore, the content type of the sound playing request can be obtained according to the content classification corresponding to the source information.
In a specific implementation, the sound attribute information described in the sound playing request may generally represent a content type of the sound playing request. For example, the sound name in the sound attribute information may be a song name, and thus the sound attribute information may belong to a music category. For another example, the sound author in the sound attribute information may be "a certain english training class", so that the sound attribute information may belong to a teaching classification.
Step 204, matching target users in the intelligent cabin according to the content type and preset sound playing configuration information; wherein, the sound playing configuration information records the corresponding relation between the content type and the user;
in the embodiment of the present invention, a sound playing configuration information may be set, and the sound playing configuration information may record a corresponding relationship between the content type and the user, so that a target user corresponding to the content type of the sound playing request may be matched in the intelligent cabin according to the sound playing configuration information.
Specifically, the content type of the sound playing request that each user in the smart car can receive can be known based on the correspondence between the content type that can be described by the sound playing configuration information and the user, so that the smart car can know a target user that can listen to the sound of the sound playing request according to the sound playing configuration information and the content type of the sound playing request.
As an example of the present invention, the sound playing configuration information may record that the content type corresponding to the driver user includes a driving-related type, and after receiving a sound playing request of the driving-related type, the driver user may be determined to be the target user according to a correspondence between the driver user and the driving-related type recorded in the sound playing configuration information.
As an example of the present invention, the sound playing configuration information may record that the content types corresponding to all users in the smart car include a music type, and when a sound playing request of the music type is received, all users in the smart car may be regarded as target users according to the correspondence between the music type recorded in the sound playing configuration information and all users in the smart car.
And step 206, searching the position of the target user in the intelligent cabin.
In the embodiment of the present invention, after determining a target user in the intelligent cabin, who needs to listen to the content type, the location of the target user in the intelligent cabin may be searched in the intelligent cabin, so that the sound corresponding to the sound playing request is played directionally based on the location of the target user in the intelligent cabin.
In a specific implementation, the position of the target user in the intelligent cabin can be searched in a manner of identifying the biological characteristic information of the user. The biometric information may include face feature information, voice feature information, fingerprint feature information, and the like, which is not limited in the present invention.
As an example of the present invention, after a target user is determined, an image in the intelligent cabin may be captured through an image capturing device in the intelligent cabin, and facial feature information of the target user is identified in the image, so as to determine a position of the target user in the intelligent cabin.
And 208, aiming at the target user, playing the sound corresponding to the sound playing request to the target user by adopting at least one loudspeaker of which the distance from the target user to the position of the intelligent cabin is smaller than the preset distance.
In the embodiment of the present invention, a plurality of speakers may be disposed in the intelligent cabin, and the plurality of speakers may be disposed at different positions in the intelligent cabin, for example, positions of a cabin top, a cabin bottom, a cabin side, a cabin front, a cabin rear, a seat back, a seat bottom, a console, and the like in the intelligent cabin, which is not limited in this respect. Therefore, the loudspeakers arranged at different positions can be respectively pointed to different users. A user to whom the speaker is pointed may hear the speaker playing content more easily, while a user to whom the speaker is not pointed may hear less easily or cannot hear the speaker playing content.
Generally, if the distance between the speaker and the position of the user in the smart car is less than a preset distance, the speaker may be considered to play sound directionally to the user. Therefore, after the position of the target user is found, at least one speaker, the distance between which and the position of the target user in the intelligent cabin is smaller than the preset distance, can be adopted for the target user to play the sound corresponding to the sound playing request to the target user. Therefore, the target user can listen to the sound corresponding to the sound playing request without interfering other users to listen to other sounds.
As an example of the present invention, fig. 3 is a schematic diagram of an intelligent cabin in an embodiment of the present invention. The smart cabin may include a primary seat 301, a secondary seat 302, a first rear seat 303, and a second rear seat 304. The intelligent cabin is provided with playing equipment at different positions respectively. Specifically, the first playback device 305 is disposed on the left side of the main driver seat 301, the second playback device 306 is disposed between the main driver seat 301 and the assistant driver seat 302, the third playback device 307 is disposed on the right side of the assistant driver seat 302, the fourth playback device 308 is disposed on the right side of the second rear seat 304, the fifth playback device 309 is disposed on the back of the second rear seat 304, the sixth playback device 210 is disposed on the back of the first rear seat 303, the seventh playback device 211 is disposed on the left side of the first rear seat 303, the eighth playback device 212 is disposed in the center of the first rear seat 303, the second rear seat 304, the main driver seat 301, and the assistant driver seat 302, the ninth playback device 213 is disposed on the back of the main driver seat 301, and the tenth playback device 214 is disposed at the console in front of the main driver seat 301.
After receiving the sound playing request, it may be determined that a source application of the sound playing request is a navigation application, so that a content type corresponding to the sound playing request may be a navigation type. Then, according to the content type and preset sound playing configuration information, a target user can be matched in the intelligent cabin as a driver user, and the position of the driver user in the intelligent cabin on the main driving seat 301 can be searched. Thereafter, the first playback device 301, the ninth playback device 313, and the tenth playback device 314, which are close to the main seat 301, may be used to play back the sound corresponding to the sound playback request to the target user at the position of the main seat 301.
After receiving the sound playing request, it may be determined that a source application of the sound playing request is a game application, so that a content type corresponding to the sound playing request may be a game type. Then, according to the content type and preset sound playing configuration information, target users, namely user a and user B, can be matched in the intelligent cabin, and the positions of the user a and the user B in the intelligent cabin on the first rear seat 303 and the second rear seat 304 are searched. Thereafter, the fourth playback device 308, the fifth playback device 309, the sixth playback device 310, and the seventh playback device 311 that are close to the first rear seat 303 and the second rear seat 304 may be used to play back the sound corresponding to the sound playback request to the target user at the position of the first rear seat 303 and the second rear seat 304.
In an embodiment of the present invention, the step of playing, for the target user, the sound corresponding to the sound playing request to the target user by using at least one speaker whose distance from the position of the target user in the smart car is smaller than a preset distance includes:
s21, under the condition that the speakers with the distance to the position of the target user in the intelligent cabin less than the preset distance are playing other sounds, selecting part of the speakers with the distance to the position of the target user in the intelligent cabin less than the preset distance as target playing equipment;
in the embodiment of the present invention, before the sound corresponding to the sound playing request is played, the speaker whose distance from the target user to the position in the smart car is less than the preset distance may already be playing other sounds. In this case, in order to not interrupt other sounds currently being played, a part of the speakers may be selected as the target playing device from the speakers whose distance from the position of the target user in the smart car is less than the preset distance, and the other speakers that are not selected as the target playing device may continue to play the sounds being played.
Specifically, there may be a difference between the speaker whose distance from the position of the target user in the smart car is less than the preset distance and the user to which the target user can be directed. For example, a speaker provided on the back of a seat may be directed only to a user seated in the seat. And the speakers arranged at the side of the cabin can be simultaneously directed to users in a plurality of seats due to the playing volume, the setting direction and the like. Therefore, when a part of the loudspeakers are selected as the target playing device, the target playing device can be determined according to the content type of the sound playing request and the user to which the loudspeakers can be directed. For example, in a case where the content type of the sound reproduction request is a call type, a call sound may be heard only by a target user seated in a certain seat, and a speaker directed only to the seat may be selected as the target reproduction device. For another example, in a case where the content type of the sound playing request is a music type, if there may be a target user who is seated in a plurality of seats in the smart car and wishes to hear the target user, a speaker that may be directed to the users in the plurality of seats may be selected as the target playing device.
And S22, playing the sound corresponding to the sound playing request to the target user by adopting the target playing device.
In the embodiment of the present invention, the target playback device may be adopted to play the sound corresponding to the sound playback request to the target user.
