Description

Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a method, apparatus, and vehicle for adjusting the sound effects of a vehicle audio source. Background Technology

[0002] Currently, in the automotive industry, with the continuous advancement of digitalization and networking, the types and functions of vehicles are constantly being improved to better meet the various needs of drivers and passengers (collectively referred to as "occupants") during vehicle use. For example, when occupants need to check driving routes, the vehicle's navigation system can broadcast navigation route information to them in real time; when occupants feel bored during the journey, the vehicle's multimedia equipment can play music for them; when there are safety hazards during the ride, the vehicle's safety monitoring system can broadcast alarm prompts to them.

[0003] In the aforementioned different application scenarios, how to intelligently adjust the sound source and sound effects in the vehicle has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a method, device, and vehicle for adjusting vehicle audio source effects. The method can intelligently provide different adjustment parameters to control the vehicle to switch to different audio source effects according to different audio scenarios, thereby meeting the diversified needs of different audio scenarios and improving the riding experience of drivers and passengers in the vehicle.

[0005] Firstly, a method for adjusting vehicle audio source effects is provided. The method includes: acquiring audio scene determination information of the vehicle, which includes the vehicle's driving parameters, the attributes of the occupants in the vehicle, and the location of the occupants; determining a target adjustment parameter corresponding to the audio scene determination information based on the audio scene determination information; and adjusting the vehicle's audio source effects based on the target adjustment parameters, whereby the audio source effects represent the audio source type and playback effect of the audio in the vehicle.

[0006] The above-mentioned technical solution proposes a method for adjusting vehicle audio source effects. Specifically, it first acquires audio scene determination information for the current vehicle, including vehicle driving parameters, and the attributes and positions of the occupants. Based on this audio scene determination information, target adjustment parameters corresponding to the audio scene determination information can be determined. Finally, the vehicle's audio source effects are adjusted based on these target adjustment parameters. This method, by determining different adjustment parameters according to different audio scene determination information to switch the vehicle's audio source effects, achieves a flexible and intelligent adjustment process for the vehicle's audio source effects, meeting the needs of different audio scenarios, avoiding the rigidity caused by fixed audio source effects, and improving the riding experience for occupants.

[0007] In conjunction with the first aspect, in some possible implementations, before determining the target adjustment parameter corresponding to the audio scene determination information based on the audio scene determination information, the method further includes: determining the adjustment mode of the vehicle audio source sound effect, wherein the adjustment mode is a manual adjustment mode or an automatic adjustment mode; and determining the target adjustment parameter corresponding to the audio scene determination information based on the audio scene determination information includes: if the adjustment mode is the manual adjustment mode, determining whether there is a configured adjustment parameter, wherein the configured adjustment parameter is an adjustment parameter pre-configured by the driver / passenger corresponding to the audio scene determination information; if the configured adjustment parameter exists, determining the configured adjustment parameter as the target adjustment parameter; if the configured adjustment parameter does not exist, determining a preset adjustment parameter as the target adjustment parameter.

[0008] The above technical solution provides a scenario for determining the target adjustment parameter. First, the adjustment mode of the vehicle's audio source is determined. In one scenario, when the adjustment mode is manual, the system can determine whether there are any pre-set adjustment parameters corresponding to the audio scene judgment information. If so, these pre-set parameters are directly determined as the target adjustment parameter. If the driver or passenger has not pre-configured them, the preset adjustment parameters are determined as the target adjustment parameter. These two methods of determining the target adjustment parameter in manual adjustment mode ensure, on the one hand, that the driver or passenger's configuration needs are prioritized when they have pre-configured, upholding a user-centric approach; on the other hand, even when the driver or passenger has not configured them, a set of adjustment parameters can be intelligently output, avoiding the problem of a decreased user experience caused by not outputting parameters when pre-configured.

[0009] In combination with the first aspect and the above implementation methods, in some possible implementation methods, after determining the configuration adjustment parameter as the target adjustment parameter, the method further includes: updating the configuration adjustment parameter in response to the driver's parameter update operation on the adjustment parameter configuration interface; and determining the updated configuration adjustment parameter as the target adjustment parameter.

[0010] The aforementioned technical solution also proposes a method for allowing drivers and passengers to update configuration adjustment parameters. After pre-configuring the adjustment parameters, if drivers and passengers wish to change the previous configuration adjustment parameters, they can reselect the adjustment parameters on the parameter configuration interface. The vehicle can then use the driver's parameter update operation to determine the reconfigured adjustment parameters as the target adjustment parameters. These target adjustment parameters can be adjusted according to actual conditions, ensuring flexibility in the target adjustment parameter determination process and further improving the passenger experience.

[0011] In conjunction with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: when the adjustment mode is the automatic adjustment mode, determining whether the audio scene determination information matches the target scene; when the audio scene determination information matches the target scene, determining the target adjustment parameter according to the first mapping relationship, wherein the first mapping relationship is used to represent the correspondence between the target scene and the target adjustment parameter.

[0012] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: when the audio scene determination information does not match the target scene, switching the target adjustment mode from the automatic adjustment mode to the manual adjustment mode, or determining the preset adjustment parameter as the target adjustment parameter.

[0013] The above technical solution proposes another scenario for determining the target adjustment parameter. When the adjustment mode is automatic, the solution can intelligently determine whether the current audio scene determination information matches the preset target scene. If they match, the target adjustment parameter is directly determined according to the first mapping relationship corresponding to the target scene. If they do not match, in one case, the adjustment mode can be switched to manual adjustment mode; in another case, the preset adjustment parameter can be used as the target adjustment parameter. This ensures that in automatic adjustment mode, when the audio scene determination information successfully matches the target scene, the target adjustment parameter is intelligently output according to the pre-established mapping relationship. On the other hand, in the case of mismatch, the autonomous configuration needs of the driver and passengers can be considered or the preset adjustment parameter can be directly output, thus achieving diversity and flexibility in determining the target adjustment parameter.

[0014] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: in response to the parameter configuration operation of the configuration personnel on the parameter configuration interface, determining multiple sets of scenarios and the adjustment parameters corresponding to each set of scenarios; and establishing the first mapping relationship based on each set of scenarios and the adjustment parameters corresponding to each set of scenarios.

[0015] In combination with the first aspect and the above implementation methods, in some possible implementation methods, adjusting the sound source effect of the vehicle according to the target adjustment parameter includes: adjusting the audio system and speakers in the vehicle according to the target adjustment parameter so that the audio system and speakers operate at the target adjustment parameter.

[0016] In the above technical solution, when adjusting the sound source and sound effects of the vehicle according to the target adjustment parameters, this application mainly controls the audio system and speakers in the vehicle, so that it can operate according to the target adjustment parameters and provide a more comfortable and pleasant riding atmosphere and riding experience for the driver and passengers.

[0017] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the acquisition of vehicle audio scene determination information includes: acquiring the driving parameters and the location of the driver and passenger through sensors; and acquiring the attributes of the driver and passenger through the vehicle monitoring platform and the configuration operations of the driver and passenger on the vehicle terminal interface.

[0018] In conjunction with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the attributes of the driver / passenger include at least one of the following: the driver / passenger's gender, number, facial emotions, body movements, age, and relationship with other drivers / passengers. Obtaining the driver / passenger's attributes through the vehicle monitoring platform and the driver / passenger's configuration operations on the vehicle terminal interface includes: obtaining at least one of the driver / passenger's gender, number, facial emotions, body movements, and age through the vehicle monitoring platform; and obtaining the driver / passenger's relationship with other drivers / passengers through the driver / passenger's configuration operations on the vehicle terminal interface.

[0019] Secondly, a device for adjusting the sound effects of a vehicle audio source is provided. The device includes: an acquisition module for acquiring audio scene determination information of the vehicle, the audio scene determination information representing the vehicle's driving parameters, the attributes of the occupants in the vehicle, and the position of the occupants; a first determination module for determining a target adjustment parameter corresponding to the audio scene determination information based on the audio scene determination information; and an adjustment module for adjusting the sound effects of the vehicle audio source based on the target adjustment parameter, the sound effects representing the audio source type and playback effect of the audio in the vehicle.

[0020] In conjunction with the second aspect, in some possible implementations, before determining the target adjustment parameter corresponding to the audio scene determination information based on the audio scene determination information, the device further includes: a second determining module, used to determine the adjustment mode of the vehicle audio source sound effect, the adjustment mode being a manual adjustment mode or an automatic adjustment mode; and the first determining module is specifically used to: when the adjustment mode is the manual adjustment mode, determine whether there is a configured adjustment parameter, the configured adjustment parameter being an adjustment parameter pre-configured by the driver / passenger corresponding to the audio scene determination information; when the configured adjustment parameter exists, determine the configured adjustment parameter as the target adjustment parameter; when the configured adjustment parameter does not exist, determine the preset adjustment parameter as the target adjustment parameter.

[0021] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, after determining the configuration adjustment parameter as the target adjustment parameter, the device further includes: a first processing module, used to update the configuration adjustment parameter in response to the driver's parameter update operation on the adjustment parameter configuration interface; and to determine the updated configuration adjustment parameter as the target adjustment parameter.

[0022] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the device further includes: a third determining module, used to determine whether the audio scene determination information matches the target scene when the adjustment mode is the automatic adjustment mode; and when the audio scene determination information matches the target scene, to determine the target adjustment parameter according to the first mapping relationship, wherein the first mapping relationship is used to represent the correspondence between the target scene and the target adjustment parameter.

[0023] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the device further includes: a second processing module, used to switch the target adjustment mode from the automatic adjustment mode to the manual adjustment mode when the audio scene determination information does not match the target scene, or to determine the preset adjustment parameter as the target adjustment parameter.

[0024] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the device further includes: a third processing module, used to respond to the parameter configuration operation performed by the configuration personnel on the parameter configuration interface, determine multiple sets of scenarios and the adjustment parameters corresponding to each set of scenarios; and establish the first mapping relationship based on each set of scenarios and the adjustment parameters corresponding to each set of scenarios.

[0025] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the adjustment module is specifically used to: adjust the audio system and speakers in the vehicle according to the target adjustment parameters, so that the audio system and speakers operate at the target adjustment parameters.

[0026] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the acquisition module is specifically used to: acquire the driving parameters and the location of the driver and passenger through sensors; and acquire the attributes of the driver and passenger through the vehicle monitoring platform and the configuration operations of the driver and passenger on the vehicle terminal interface.

[0027] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the attributes of the driver / passenger include at least one of the following: the driver / passenger's gender, number, facial emotions, body movements, age, and relationship with other drivers / passengers. The acquisition module is also used to: acquire at least one of the driver / passenger's gender, number, facial emotions, body movements, and age through the vehicle monitoring platform; and acquire the relationship between the driver / passenger and other drivers / passengers through the driver / passenger's configuration operations on the vehicle terminal interface.

[0028] Thirdly, a vehicle is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the methods described in the first aspect or any possible implementation thereof.

[0035] Figure 5 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation

[0036] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] Figure 1 This is a schematic diagram of a scenario for adjusting the sound effects of a vehicle audio source, provided in an embodiment of this application.

[0039] For example, such as Figure 1 As shown, vehicle 101 contains passengers. During operation, to provide a better riding experience for the passengers, different audio scenarios and adjustment parameters can be determined based on different driving conditions. Furthermore, the sound source effects in vehicle 101 are adjusted according to these different parameters to create a pleasant and comfortable riding atmosphere for the passengers.

[0040] When determining different adjustment parameters, vehicle 101 can provide two adjustment modes: an automatic adjustment mode and a manual adjustment mode. The automatic adjustment mode relies primarily on the scene engine within vehicle 101. The scene engine uses artificial intelligence (AI) algorithms to process the acquired current audio scene information and determine which scene the current audio scene belongs to. Based on the determination result, vehicle 101 intelligently outputs the corresponding adjustment parameters. The other adjustment mode is the manual adjustment mode, where the driver and passengers manually set the adjustment parameters.

[0041] It should be understood that, regardless of the adjustment mode, the configuration personnel can pre-configure multiple sets of adjustment parameters (also known as sound source-sound effect parameters). After the configuration is completed, the vehicle 101 can also store multiple sets of adjustment parameters.

[0042] In one possible implementation, vehicle 101 can store pre-set adjustment parameters in server 102. When vehicle 101 needs to obtain the adjustment parameters required for the current audio scene, it can send a request to server 102 through a remote communication module in vehicle 101 (e.g., a remote vehicle terminal (Telematics BOX, T-BOX)) to obtain the current adjustment parameters.

[0043] In another possible implementation, vehicle 101 can also store the pre-set adjustment parameters locally on vehicle 101, such as in any memory or local disk of vehicle 101. When vehicle 101 needs to obtain the adjustment parameters, it can directly obtain them from the local device. This application embodiment does not limit this approach.

[0044] Figure 2This is a schematic flowchart illustrating a method for adjusting the sound effects of a vehicle audio source according to an embodiment of this application. It should be understood that this method can be applied to... Figure 1 The scenarios described, specifically applied to Figure 1 Any electronic control unit (ECU) in vehicle 101.

[0045] For example, such as Figure 2 As shown, the method 200 includes:

[0046] 201. Obtain the vehicle's audio scene determination information, which includes the vehicle's driving parameters, the attributes of the occupants in the vehicle, and the location of the occupants.

[0047] It should be understood that the primary purpose of vehicle audio sources and effects is to provide a better riding atmosphere for passengers. In other words, adjusting vehicle audio sources and effects is inseparable from the vehicle's own status and the relevant information of the passengers. Therefore, before adjusting the vehicle's audio sources and effects, it is necessary to first obtain the current vehicle status information and the relevant information of the passengers to determine the current audio scene. The vehicle status information can be understood as the vehicle's driving parameters, including engine speed, vehicle speed, acceleration, steering wheel speed, and other driving-related parameters. The relevant information of the passengers can include their attributes and positions. Passenger attributes can represent their basic information, actions, and number. For example, basic information could include age and gender, and actions could include body language and facial expressions during the ride. Passenger positions can represent the relative positions of the passengers to their seats. All of the above parameters can be collectively referred to as "audio scene determination information."

[0048] One possible implementation involves obtaining the vehicle's audio scene determination information, specifically including:

[0049] The system uses sensors to acquire driving parameters and the location of passengers.

[0050] The attributes of drivers and passengers can be obtained through the vehicle monitoring platform and the configuration operations performed by drivers and passengers on the vehicle terminal interface.

[0051] Furthermore, the attributes of the drivers and passengers include at least one of the following: gender, number, facial expressions, body language, age, and relationship with other drivers and passengers. The steps for obtaining these attributes may specifically include:

[0052] The vehicle monitoring platform obtains at least one of the following information: gender, number of passengers, facial expressions, body movements, and age of the driver and passengers.

[0053] The relationship between drivers and passengers can be obtained through configuration operations performed by drivers and passengers on the in-vehicle terminal interface.

[0054] For example, in this embodiment of the application, the vehicle's driving parameters include parameters such as vehicle speed and acceleration, and the position of the occupants is the relative position of the driver and the seat, which can be represented by the tilt angle of the seat. Therefore, the vehicle can obtain the driving speed based on its own speed sensor, the acceleration through the acceleration sensor, and the seat tilt angle through the angle sensor on the seat to further determine the position of the occupants.

[0055] Another example is that the location of occupants can be determined by combining a pressure sensor under the seat with a camera in the vehicle. The pressure sensor can detect whether someone is in the seat, and if so, the location of the occupant can be determined by combining this information with image data from the camera.

[0056] In-vehicle monitoring platforms can monitor driver and passenger images in real time via cameras. Utilizing AI algorithms and deep neural networks, and employing core technologies such as face detection and tracking, and 3D facial modeling, they can obtain the driver's and passenger's body movements and facial emotions. Furthermore, deep neural networks can extract features from the driver's and passenger's images to obtain their facial features. Further comparison and analysis of these facial features can then determine the driver's and passenger's age and gender.

[0057] Optionally, the in-vehicle monitoring platform can be a Video Intelligent Maintenance System (VIMS). VIMS acts as the eyes of the vehicle, directly observing the behavior of the occupants inside the vehicle to infer their needs. It can also be integrated with the vehicle's voice system, navigation system, and scene engine.

[0058] Optionally, VIMS mainly includes a Driver Monitor System (DMS) and an Occupant Monitoring System (OMS). The DMS can perform facial recognition, distraction monitoring (e.g., mild, moderate, severe distraction), fatigue monitoring (mild, moderate, severe fatigue), emotion recognition (e.g., happy, angry emotions), basic information recognition (age and gender), and behavior monitoring (smoking, phone use, water consumption). The OMS can perform identity verification, basic information verification, passenger quantity monitoring, passenger emotion recognition, and passenger behavior monitoring for passengers.

[0059] Therefore, based on the information collected by the vehicle monitoring platform, this application embodiment can obtain information such as the gender, number, facial emotions, body movements, and age of the driver and passengers.

[0060] It should be understood that the relationship between drivers and passengers can be interpreted as specifying which of the following relationships exists between the driver and passengers: boyfriend / girlfriend, father / son, husband / wife, father / daughter, mother / son, friends, superior / subordinate, etc. Since various in-vehicle applications exist, some may require drivers and passengers to log in to their accounts before configuration and operation. Therefore, by observing the driver's / passenger's login and subsequent configuration operations on the in-vehicle terminal interface, the relationship between drivers and passengers can be determined.

[0061] For example, for a music app in a vehicle, occupants can log in and access the app's settings. They can then search for keywords such as "children's songs" or "cartoon theme songs" and select the desired song. Based on this settings, the vehicle's cameras can capture facial images of all occupants. By comparing and recognizing these images, the vehicle can determine the gender and age of each occupant and infer whether they are related as parents or children.

[0062] 202. Based on the audio scene determination information, determine the target adjustment parameters corresponding to the audio scene determination information.

[0063] It should be understood that when a vehicle leaves the factory, the configuration personnel can pre-configure multiple sets of adjustment parameters and store them locally on the vehicle or on a server, so as to facilitate the subsequent determination of the vehicle's target adjustment parameters.

[0064] It should also be understood that the adjustment parameters are used to adjust the vehicle's audio source and sound effects. Common types of audio sources in vehicles can be categorized according to their origin: music sources (including local and online music sources), audio-visual sources (such as movie and musical audio sources), film and television sources (such as TV series audio sources), audiobook narration sources, entertainment sources (short videos, games, etc.), navigation sources, communication sources, voice interaction sources, voice broadcast sources, and alarm sources (radar sounds, turn signals, and emergency rescue sounds). Audio effect parameters can include: amplifier / audio system type (e.g., external amplifier, internal amplifier), speaker location (driver's speaker, passenger's speaker, rear speakers, etc.), sound effect type (surround sound, stereo, immersive sound, etc.), volume level, equalizer levels, channel type (e.g., left channel, right channel), bass and treble, noise cancellation mode, and listening position. Therefore, each set of adjustment parameters actually refers to a set of sound source-sound effect parameters, specifically including the type of sound source and the parameters of the sound effect.

[0065] Table 1 is an illustrative table of sound source-sound effect parameters corresponding to an audio scene provided in an embodiment of this application.

[0066] Table 1

[0068] For example, as shown in Table 1, the configuration personnel can pre-set multiple sets of sound source-sound effect parameters, such as those mentioned above. For example, sound source-sound effect parameter 1, sound source-sound effect parameter 2, sound source-sound effect parameter 3, etc.

[0069] It should be understood that in this embodiment, two adjustment modes are provided when adjusting the vehicle's audio source effects: manual adjustment mode and automatic adjustment mode. The process for determining the adjustment parameters differs for each adjustment mode. Therefore, when determining the target adjustment parameters based on audio scene judgment information, it is first necessary to determine the vehicle's adjustment mode. Then, based on the corresponding adjustment mode, the target adjustment parameters are determined.

[0070] One possible implementation involves determining the adjustment mode of the vehicle's audio source sound effects, specifically including:

[0071] Determine the adjustment mode for the vehicle's audio source and sound effects; the adjustment mode can be manual or automatic.

[0072] For example, when determining the adjustment mode of the vehicle's audio source, the vehicle can identify the current adjustment mode by acquiring the status information of different adjustment modes. This status information includes whether the mode is on or off. If the "manual adjustment mode" is on, the current adjustment mode is manual; otherwise, it is automatic. If both adjustment modes are off, the driver and passengers can choose according to their needs.

[0073] Furthermore, after determining the adjustment mode of the vehicle's audio source and sound effects, the target adjustment parameters corresponding to the audio scene determination information can be determined based on the audio scene determination information.

[0074] In one possible implementation, the adjustment mode can be a manual adjustment mode. In manual adjustment mode, the process of determining the target adjustment parameter specifically includes:

[0075] When the adjustment mode is manual adjustment mode, it is determined whether there are configured adjustment parameters. The configured adjustment parameters are the adjustment parameters pre-configured by the driver and passengers that correspond to the audio scene determination information.

[0076] If the configuration adjustment parameter exists, the configuration adjustment parameter will be determined as the target adjustment parameter;

[0077] If the configured adjustment parameter does not exist, the preset adjustment parameter will be set as the target adjustment parameter.

[0078] When the adjustment mode is manual, in one scenario, the driver or passenger can pre-configure a set of adjustment parameters corresponding to the audio scene determination information (e.g., sound source-sound effect parameter 1) by clicking on the selection operation in the adjustment parameter configuration interface. Furthermore, if the vehicle detects that the current audio scene determination information has an adjustment parameter, namely sound source-sound effect parameter 1, then the vehicle can directly determine sound source-sound effect parameter 1 as the target adjustment parameter.

[0079] Figure 3 This is a schematic diagram of a scenario where manually configuring and adjusting parameters is provided in an embodiment of this application.

[0080] For example, such as Figure 3 As shown in Table 1, the parameter configuration interface 301 includes multiple sets of pre-configured sound source-sound effect parameters, namely Sound Source-Sound Effect Parameter 1, Sound Source-Sound Effect Adoption Count 2, Sound Source-Sound Effect Parameter 3, Sound Source-Sound Effect Parameter 4, Sound Source-Sound Effect Parameter 5, Sound Source-Sound Effect Parameter 6, and Default Sound Source-Sound Effect Parameter. Each set of sound source-sound effect parameters can be selected by clicking the corresponding "○" icon.

[0081] When a driver or passenger is in a specific audio scenario, they can click the "○" icon corresponding to Audio Source-Sound Effect Parameter 1 to set it as the configuration adjustment parameter for that audio scenario. During subsequent driving, the vehicle uses real-time audio scenario detection information to identify the currently existing configuration adjustment parameter—Audio Source-Sound Effect Parameter 1—and then sets it as the target adjustment parameter.

[0082] Furthermore, after setting the configuration adjustment parameters as the target adjustment parameters, drivers and passengers can also adjust the configuration adjustment parameters according to the actual situation, specifically including:

[0083] In response to the driver's or passenger's parameter update operation on the parameter configuration interface, update the configuration adjustment parameters;

[0084] The updated configuration adjustment parameters are set as the target adjustment parameters.

[0085] For example, such as Figure 3 As shown, if the driver or passenger wants to adjust the target adjustment parameter of the current output—sound source-sound effect parameter 1—they can click to select the icon corresponding to any other set of sound source-sound effect parameters to update the target adjustment parameter.

[0086] Another example is that drivers and passengers can also control the vehicle to update configuration adjustment parameters via voice commands. For instance, drivers and passengers can use the voice command "switch to audio source - audio effect parameter 3" to control the vehicle to update the current configuration adjustment parameters.

[0087] The aforementioned technical solution also proposes a method for allowing drivers and passengers to update configuration adjustment parameters. After pre-configuring the adjustment parameters, if drivers and passengers wish to change the previous configuration adjustment parameters, they can reselect the adjustment parameters on the parameter configuration interface. The vehicle can then use the driver's parameter update operation to determine the reconfigured adjustment parameters as the target adjustment parameters. These target adjustment parameters can be adjusted according to actual conditions, ensuring flexibility in the target adjustment parameter determination process and further improving the passenger experience.

[0088] In another scenario, if the driver or passengers have not configured the settings in the parameter settings interface, and the vehicle's detection result indicates that no configuration parameters exist, the vehicle can output default (or preset) adjustment parameters. For example... Figure 3 As shown, the vehicle can output default sound source-sound effect parameters as target adjustment parameters.

[0089] It should be noted that the audio source-sound effect parameter 1 pre-configured by the driver and passengers can be the same as or different from the default adjustment parameter, and this application embodiment does not limit this.

[0090] Similarly, if drivers and passengers want to adjust the current default audio source and sound effect parameters, they can do so by selecting the icon corresponding to any other set of audio source and sound effect parameters through the same method described above.

[0091] The above technical solution provides a scenario for determining the target adjustment parameter. First, the adjustment mode of the vehicle's audio source is determined. In one scenario, when the adjustment mode is manual, the system can determine whether there are any pre-set adjustment parameters corresponding to the audio scene judgment information. If so, these pre-set parameters are directly determined as the target adjustment parameter. If the driver or passenger has not pre-configured them, the preset adjustment parameters are determined as the target adjustment parameter. These two methods of determining the target adjustment parameter in manual adjustment mode ensure, on the one hand, that the driver or passenger's configuration needs are prioritized when they have pre-configured, upholding a user-centric approach; on the other hand, even when the driver or passenger has not configured them, a set of adjustment parameters can be intelligently output, avoiding the problem of a decreased user experience caused by not outputting parameters when pre-configured.

[0092] In another possible implementation, the adjustment mode can be an automatic adjustment mode.

[0093] It should be understood that in automatic adjustment mode, the vehicle's scene engine primarily matches audio scene determination information with multiple preset scene sets to determine if a match is successful. Each scene set corresponds to a unique set of sound source-sound effect parameters. The correspondence between scenes and sound source-sound effect parameters is pre-configured by the administrator.

[0094] One possible implementation involves configuring multiple sets of correspondences between scenes and sound source-sound effect parameters, specifically including:

[0095] In response to the parameter configuration operations performed by the configuration personnel on the parameter configuration interface, determine multiple sets of scenarios and the corresponding adjustment parameters for each set of scenarios.

[0096] A first mapping relationship is established based on each set of scenarios and the corresponding adjustment parameters.

[0097] For example, following the method in Table 1, the configuration personnel have pre-determined multiple sets of sound source-sound effect parameters. During the process of configuring the correspondence between scenarios and sound source-sound effect parameters, the configuration personnel can perform real-vehicle calibration based on the actual scenarios of the vehicle, thereby determining multiple preset scenarios and the corresponding sound source-sound effect parameters for each scenario. Thus, based on each scenario and its corresponding sound source-sound effect parameters, a first mapping relationship is established.

[0098] Furthermore, in automatic adjustment mode, the process of determining the target adjustment parameter specifically includes:

[0099] When the adjustment mode is set to automatic adjustment mode, determine whether the audio scene determination information matches the target scene;

[0100] In one scenario, if the audio scene determination information matches the target scene, the target adjustment parameters are determined based on the first mapping relationship, which represents the correspondence between the target scene and the target adjustment parameters.

[0101] In another scenario, if the audio scene determination information does not match the target scene, the target adjustment mode is switched from automatic adjustment mode to manual adjustment mode, or the preset adjustment parameters are set as the target adjustment parameters.

[0102] In automatic adjustment mode, if the current audio scene determination information matches the preset target scene, the target adjustment parameter can be directly determined according to the first mapping relationship; if the current audio scene determination information does not match the preset target scene, the adjustment mode needs to be switched from automatic adjustment mode to manual adjustment mode, and the driver and passengers can determine the target adjustment parameter according to the above manual adjustment method, or the default (preset) adjustment parameter can be directly used as the target adjustment parameter.

[0103] The above technical solution proposes another scenario for determining the target adjustment parameter. When the adjustment mode is automatic, the solution can intelligently determine whether the current audio scene determination information matches the preset target scene. If they match, the target adjustment parameter is directly determined according to the first mapping relationship corresponding to the target scene. If they do not match, in one case, the adjustment mode can be switched to manual adjustment mode; in another case, the preset adjustment parameter can be used as the target adjustment parameter. This ensures that in automatic adjustment mode, when the audio scene determination information successfully matches the target scene, the target adjustment parameter is intelligently output according to the pre-established mapping relationship. On the other hand, in the case of mismatch, the autonomous configuration needs of the driver and passengers can be considered or the preset adjustment parameter can be directly output, thus achieving diversity and flexibility in determining the target adjustment parameter.

[0104] 203. Adjust the vehicle's audio source and sound effects according to the target adjustment parameters. The audio source and sound effects are used to represent the audio source type and audio playback effect in the vehicle.

[0105] Specifically, when adjusting the vehicle's audio source and sound effects according to the target adjustment parameters, the main focus is on adjusting the operating parameters and status of the vehicle's audio system and speakers, including:

[0106] Adjust the audio system and speakers in the vehicle according to the target adjustment parameters so that they operate at the target adjustment parameters.

[0107] In summary, this application proposes a method for adjusting vehicle audio source effects. Specifically, it first acquires audio scene determination information for the current vehicle, including vehicle driving parameters and the attributes and positions of the occupants. Based on this audio scene determination information, target adjustment parameters corresponding to the audio scene determination information can be determined. Finally, the vehicle's audio source effects are adjusted based on these target adjustment parameters. This method, which determines different adjustment parameters according to different audio scene determination information to switch the vehicle's audio source effects, achieves a flexible and intelligent adjustment process for the vehicle's audio source effects, meeting the needs of different audio scenarios, avoiding the rigidity of fixed audio source effects, and improving the riding experience for occupants.

[0108] Specifically, this application provides a scenario for determining target adjustment parameters. First, the adjustment mode of the vehicle's audio source is determined. In one scenario, when the adjustment mode is manual, the system can determine whether there are any pre-set configuration adjustment parameters corresponding to the audio scene determination information based on the audio scene judgment information. If so, the configuration adjustment parameters are directly determined as the target adjustment parameters; if the driver or passenger has not pre-configured them, the preset adjustment parameters are determined as the target adjustment parameters. These two methods of determining target adjustment parameters in manual adjustment mode ensure, on the one hand, that the driver or passenger's configuration needs are prioritized when they have pre-configured, thus upholding a user-centric approach; on the other hand, even when the driver or passenger has not configured them, a set of adjustment parameters can be intelligently output, avoiding the problem of a decreased user experience caused by not outputting parameters when the driver or passenger has not pre-configured them.

[0109] Furthermore, this application proposes a scheme that allows drivers and passengers to update configuration adjustment parameters. After pre-configuring the adjustment parameters, if drivers and passengers wish to change the previous configuration adjustment parameters, they can reselect the adjustment parameters on the adjustment parameter configuration interface. The vehicle can then determine the reconfigured adjustment parameters as the target adjustment parameters based on the driver's parameter update operation. These target adjustment parameters can be adjusted according to actual conditions, ensuring flexibility in the target adjustment parameter determination process and further improving the passenger experience.

[0110] In another scenario, this application also proposes another way to determine the target adjustment parameter. When the adjustment mode is automatic, the solution of this application can intelligently determine whether the current audio scene determination information matches the preset target scene. If they match, the target adjustment parameter is directly determined according to the first mapping relationship corresponding to the target scene; if they do not match, in one case, the adjustment mode can be switched to manual adjustment mode, and in another case, the preset adjustment parameter can be used as the target adjustment parameter. This ensures that in automatic adjustment mode, when the audio scene determination information successfully matches the target scene, the target adjustment parameter is intelligently output according to the pre-established mapping relationship; on the other hand, in the case of mismatch, the autonomous configuration needs of the driver and passengers can be considered or the preset adjustment parameter can be directly output, thus realizing the diversity and flexibility of determining the target adjustment parameter.

[0111] Finally, when adjusting the vehicle's sound source and sound effects according to the target adjustment parameters, this application mainly controls the vehicle's audio system and speakers, enabling them to operate according to the target adjustment parameters and provide a more comfortable and pleasant riding atmosphere and experience for drivers and passengers.
