[0022] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are protected by the present application.
[0023] As vehicle technology develops, consumers are placing higher and higher demands on vehicles. The audio system in a traditional vehicle cockpit can support the playback of audio selected by the user. However, in actual application scenarios, different drivers and passengers have different audio needs. The driver needs to listen to navigation and driving instructions, and the rear passengers want to listen to entertainment content. When the audio system outputs the audio uniformly, the audio that different drivers and passengers need to listen to is prone to interfere with each other. In addition, drivers and passengers often have different listening needs for different audios, and the unified output of the audio system is difficult to meet the needs of different scenarios.
[0024] In view of the above findings, the present application proposes a vehicle audio output method, which can select an output device group for audio output according to different needs within the partition where audio needs to be output, while avoiding mutual interference between audios that different drivers and passengers need to listen to, and adapting to different scene requirements.
[0025] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.
[0026] Figure 1 A schematic diagram of the implementation flow of a vehicle audio output method provided in an embodiment of the present application is shown, and the method can be applied in a vehicle.
[0027] Specifically, the above-mentioned vehicle audio output method may include the following steps S101 to S104.
[0028] Step S101, obtaining audio to be output.
[0029] The audio to be output refers to the audio that the vehicle needs to output.
[0030] This application does not limit the source of the audio to be output. In some embodiments of this application, the audio to be output may be audio output by various applications in the vehicle computer, such as music output by a music application and navigation voice output by a navigation application. In other embodiments of this application, the audio to be output may also be data input by an external device connected to the vehicle computer, such as mobile phone audio transmitted to the vehicle computer via Bluetooth.
[0031] It should be noted that the obtained audio to be output may be pre-processed by noise reduction, volume adjustment, etc. to improve the output quality of the audio.
[0032] Step S102, determining a target partition to which the audio to be output needs to be output.
[0033] The target partition refers to the area where the audio to be output is currently required to be output. The target partition is a partition determined from multiple audio partitions, and the multiple audio partitions are obtained by dividing the vehicle cabin environment according to the occupant positions.
[0034] Specifically, the partitioning method of the cabin environment can be selected according to actual needs. For example, the cabin environment of the vehicle can be divided into the main driving area, the co-pilot area and the rear area, or it can be divided into multiple audio areas according to the number of seats, that is, a five-seater car can be divided into five audio partitions corresponding to the five seats. In some embodiments of the present application, the vehicle can also support users to manually divide the area, for example, the user performs touch screen operation on the vehicle display screen to manually divide the cabin environment into multiple audio partitions.
[0035] Among the multiple audio partitions, according to the audio output requirement of the audio to be output, at least one audio partition can be selected as a target partition to output the audio to be output to the target partition.
[0036] Step S103, determining the current functional mode among multiple functional modes.
[0037] Different functional modes among the multiple functional modes are used to select a target output device group from a plurality of output device groups that output audio to a target partition.
[0038] In order to support different functional modes, multiple output devices can be set in the vehicle's driving environment, wherein one or more output devices can be set in each audio zone. The output device can specifically refer to a speaker or other device with audio output capability. The output devices in each audio zone can include but are not limited to: headrest speakers, door speakers, backrest speakers, and front speakers of the seat.
[0039] For a single audio zone, multiple audio output modes can be configured, and each audio output mode corresponds to a functional mode and an output device group. Each output device group can include one or more output devices, and the number, position or other parameters of output devices are different between different output device groups. For example, for a single audio zone, the headrest speakers in the audio zone are individually used as an output device group, and all speakers in the audio zone can be used as another output device group.
[0040] Among multiple functional modes, the current functional mode can be determined based on the output requirements of the audio to be output, so as to determine the corresponding target output device group according to the audio output method corresponding to the current functional mode.
[0041] Step S104: According to the current function mode, the target output device group is controlled to output the audio to be output.
[0042] Specifically, according to the current functional mode, a target output device group may be selected from a plurality of output device groups that output audio to the target partition, and the target output device group may be controlled to output the audio to be output.
[0043] In an implementation manner of the present application, a plurality of audio partitions are obtained by dividing the vehicle's cabin environment according to the positions of the passengers, the audio to be output is obtained, and the current functional mode is determined among a plurality of functional modes, so as to select a target output device group from a plurality of output device groups that output audio to the target partition, thereby controlling the target output device group to output the audio to be output to the target partition among the plurality of audio partitions, and being able to select the output device group for outputting audio according to different requirements within the partition where the audio needs to be output, thereby adapting to different scenario requirements while avoiding mutual interference between audios that different drivers and passengers need to listen to.
[0044] In some embodiments of the present application, the above-mentioned multiple functional modes may include a privacy mode and a partition mode.
[0045] In some embodiments of the present application, according to the current functional mode, controlling the target output device group to output the audio to be output may include: if the current functional mode is a privacy mode, confirming the first output device group as the target output device group, controlling the target output device group to output the audio to be output, wherein the first output device group may include headrest speakers within the target partition.
[0046] Specifically, the privacy mode is a mode for protecting the privacy of passengers, and the output devices in the first output device group selected are the headrest speakers in the target zone.
[0047] Specifically, the vehicle can determine the current functional mode through user selection or analysis of the audio type of the audio to be output. The audio type can represent the privacy level and security level of the audio to be output. The privacy level represents the sensitivity of the audio content of the audio to be output and the degree of impact on personal privacy. For example, when the audio type is a call voice, the privacy level is higher. The security level represents the importance of the audio content of the audio to be output to driving safety. For example, when the safety level is a navigation prompt voice or a driving prompt voice, the safety level is higher. If the audio type is a preset type, it means that the privacy level or security level of the audio to be output is higher than the preset level, and the privacy mode can be actively entered at this time. If the user manually selects the privacy mode or the vehicle actively enters the privacy mode, the first output device group can be determined as the target output device group to control the headrest speakers in the target partition to output the audio to be output, so as to prevent the audio content of the audio to be output from being known to other passengers.
[0048] In some embodiments, a plurality of seats and a plurality of headrest speakers corresponding to the plurality of seats may be arranged in the target partition. At this time, controlling the target output device group to output the audio to be output may include: determining a target seat in use among the plurality of seats, and controlling the headrest speaker corresponding to the target seat to output the audio to be output.
[0049] Specifically, the vehicle can determine whether there are passengers in each seat through machine vision, pressure sensor data analysis, etc., and if there are passengers, the target seat is in use.
[0050] Taking a five-seater car as an example, when the target partition is the rear area, since there are three seats in the rear area, if the rear passenger is located in the leftmost seat, the leftmost seat is the target seat in use. At this time, the headrest speaker corresponding to the leftmost seat in the first output device group can be controlled to output the audio to be output to the target partition, and the headrest speakers of other seats do not need to output the audio to be output, which can reduce the power consumption to a certain extent.
[0051] In some other implementations of the present application, if the current function mode is the partition mode, the present application provides two different output control methods for the partition mode, wherein the partition mode is a mode for controlling the audio to focus on a specific audio partition.
[0052] The first one:
[0053] According to the current functional mode, controlling the target output device group to output the audio to be output may include: if the current functional mode is the partition mode, identifying the second output device group as the target output device group, and controlling the target output device group to output the audio to be output to the target partition. The second output device group includes each speaker in the target partition.
[0054] In this way, all speakers in the target partition will be directly selected to output the audio to be output, and the speakers in other audio partitions do not need to output the audio to be output. In this way, the sound can be concentrated in the target partition, so that the driver and passengers in the target partition can better hear the audio to be output.
[0055] Second type:
[0056] According to the current function mode, controlling the target output device group to output the audio to be output may include: if the current function mode is the partition mode, the third output device group is confirmed as the target output device group, and according to the position information of the target partition in the cabin environment, the audio output parameters of each speaker in the cabin environment are determined; according to the audio output parameters, each speaker in the cabin environment is controlled to output the audio to be output, so as to focus the audio output on the target partition. The third output device group includes each speaker in the cabin environment, and the audio output parameter may refer to the sound phase.
[0057] In this way, all speakers in the cockpit environment will output the audio to be output together. However, during the output process, by adjusting the audio output parameters of each speaker, the audio output can be focused on the target zone, so that the driver and passengers in the target zone can better hear the audio to be output.
[0058] In some embodiments of the present application, Figure 2 As shown, determining the target partition where the audio to be output needs to be output may include steps S201 to S203.
[0059] Step S201, monitoring the user's selection operation on the audio partition.
[0060] Specifically, the user can trigger the selection operation of the audio partition through voice commands, touch screen operations on the vehicle display screen, etc., and this application does not impose any restrictions on this.
[0061] Step S202: If a selection operation is received, the audio partition selected by the user is used as the target partition.
[0062] Step S203: If no selection operation is received, an audio output object of the audio to be output is obtained, and the audio partition where the audio output object is located is determined as a target partition.
[0063] Specifically, if a selection operation is received, the audio partition selected by the user can be used as the target partition according to the user intention expressed by the selection operation. If no selection operation is received, the audio output object of the audio to be output can be obtained, and the target partition can be determined according to the audio output object.
[0064] For example, when the audio output object of the audio to be output is the driver, the main driving area can be determined as the target partition. For another example, when the audio output object of the audio to be output is a specific user, the audio partition seat to which the corresponding seat belongs can be determined as the target partition based on the seat where the specific user is located.
[0065] In some embodiments of the present application, the audio source information of the audio to be outputted may be determined, and the audio output object may be determined according to the audio source information, wherein the audio source information may include the vehicle-mounted functional module of the audio source to be outputted.
[0066] For details, please refer to the following Table 1:
[0067] Table 1
[0068]
[0069]
[0070] Table 1 shows the classification of vehicle-mounted functional modules. The vehicle-mounted functional modules may include: audio module, sound module, host module, audio control module, function setting module, navigation module, driving reminder module, telephone module, software application module and radio module. The above vehicle-mounted functional modules can be installed in the vehicle computer.
[0071] The sound module depends on the audio module, which is used to play sound in different areas and supports channel separation, so that the vehicle audio output can be played in different areas. The host module is based on the host hardware and the audio algorithm running inside, and is used to implement the power amplifier and audio partitioning algorithm. The audio control module is used to control the sound module to support audio partition playback. The above three vehicle-mounted functional modules can jointly run the audio output method provided in this application to realize audio partition playback. The function setting module is used to receive the user's partition design operation based on the vehicle-mounted head-up display HUT, so that the user can design audio partitions.
[0072] The navigation module depends on the audio module and can be used to obtain navigation prompts. The driving prompt module depends on the audio module, driving and parking modules and can be used to obtain driving prompts for the vehicle, such as driving status and parking status prompts. The phone module can be used for Bluetooth phone calls to obtain phone voice data from devices connected to the vehicle. The software application module can obtain audio data from applications such as video applications, music applications, children's applications, and game entertainment applications. The radio module can obtain radio sound through the radio and antenna.
[0073] By determining the vehicle-mounted functional module of the audio source to be output, and based on the vehicle-mounted functional module of the audio source to be output, the audio output object can be determined. For example, when the vehicle-mounted functional module of the audio source to be output is a navigation module or a driving prompt module, that is, the audio to be output is a navigation prompt, a driving prompt, a telephone module, etc., the audio output object can be determined to be the driver. At this time, the main driving area can be determined as the target partition.
[0074] Furthermore, when the vehicle-mounted function module of the audio source to be output is a software application module, the audio output object can be determined according to the information of the application program of the audio source to be output. For example, when the application program of the audio source to be output is a children's application, the rear passengers can be used as the audio output object. When the application program of the audio source to be output is a video application, a music application or a game entertainment application, the rear passengers and the front passenger passengers can be used as the audio output objects.
[0075] It should be noted that if the audio to be output includes audio of multiple applications, the audio output object corresponding to each application can be determined separately, and the audio of each application is output to the audio area where the corresponding audio output object is located.
[0076] Please refer to Table 2 and Figure 3 . Take the example of dividing the cockpit environment into the main driving area, the co-pilot area and the back row area. After the audio partition, the user can select the current function mode and the target partition. Based on the current function mode, if the current function mode is the partition mode, the sound can be output only in the target area, and the sound of music, radio and other functions can be output in any one or more of the main driving area, the co-pilot area and the back row area. If the current function mode is the privacy mode, the sound of telephone voice, navigation prompts, Bluetooth calls and other functions can be output through the headrest speakers in the main driving area, and the sound of music, radio, video and other functions can be output through the headrest speakers in the co-pilot area.
[0077] Table 2
[0078]
[0079] In this way, private information or information closely related to driving safety can be directly output to the driver through the headrest speakers in the main driving area, and entertainment audio such as music and videos can be output through the various speakers in the main driving area to ensure entertainment listening effects, thereby meeting the needs of different scenarios. In addition, the audio in the co-pilot area and the back row area is not likely to affect the driver, which helps to improve safety.
[0080] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited to the described order of actions, because according to the present application, certain steps can be performed in other orders.
