[0051] In this embodiment, the physiological state of the target object in the target sound field area is identified. Optionally, this embodiment identifies the eye state of the target object based on determining the target sound field area corresponding to the target function control. In response to the identified eye state being a closed state, the duration of the closed state is detected, and in response to the duration of the closed state exceeding the first target duration, the physiological state is determined to be an abnormal physiological state, wherein the first target duration may be but is not limited to 10S; in response to the identified eye state being an open state, the duration of the open state is detected, and in response to the duration of the open state exceeding the second target duration, the physiological state is determined to be a normal physiological state, wherein the second target duration may be but is not limited to 5mins.

[0052] In this embodiment, after the physiological state of the target object in the target sound field area is identified, the playback strategy is determined based on the physiological state. Optionally, based on the identified physiological state, the embodiment determines the position of the target sound field area corresponding to the target function control in the vehicle to obtain a judgment result.

[0053] Optionally, if the above judgment result is that the target sound field area is located in the driving area of ​​the vehicle, then the playback strategy of the target media playback device in the target sound field area can be determined based on the determined media data; if the above judgment result is that the target sound field area is located in the passenger area of ​​the vehicle, then the playback strategy of the target media playback device in the target sound field area can be determined based on the identified physiological state.

[0054] It should be noted that the above-mentioned method for determining the playback strategy based on media data and the method for determining the playback strategy based on physiological state are only examples and are not specifically limited here. As long as the process and method can use the determined media data and / or the identified physiological state to determine the playback strategy of the target media playback device in the target sound field area, they are all within the protection scope of the embodiments of the present application and will not be described one by one here.

[0055] It should be noted that the first target duration and the second target duration may be initialization durations or durations adjusted according to user needs, and the first target duration is smaller than the second target duration.

[0056] Step S116: controlling the working state of the target media playback device according to the playback strategy.

[0057] In the technical solution provided in the above step S116 of the present invention, the above play strategy may include a first play strategy, a second play strategy, a third play strategy and a fourth play strategy.

[0058] In this embodiment, after determining the playback strategy of the target media playback device in the target sound field area, the working state of the target media playback device is controlled according to the playback strategy. Optionally, based on the determined playback strategy, this embodiment identifies the determined playback strategy to obtain an identification result, wherein the identification result may indicate that the playback strategy is the first playback strategy, may indicate that the playback strategy is the second playback strategy, may indicate that the playback strategy is the third playback strategy, and may indicate that the playback strategy is the fourth playback strategy. According to the obtained identification result, the working state of the target media playback device may be controlled.

[0059] It should be noted that the method for playing the media data of the vehicle in the present application can also be applied to at least the following scenarios: autonomous driving scenario, assisted driving scenario and passive driving scenario (which can be referred to as human driving scenario). Among them, the autonomous driving scenario can be used to indicate that the vehicle control system controls the driving of the vehicle during the driving process, and the driving object does not need to maintain control and supervision of the driving. The assisted driving scenario can be used to indicate that the vehicle control system provides assistance during the driving process, but the driving object still needs to maintain control and supervision of the driving. The passive driving scenario can be used to indicate the scenario where the driving object controls the vehicle to complete the driving operation.

[0060] In the artificial intelligence AI driving of autonomous vehicles, commuting mode usually refers to a driving mode designed for commuting or daily commuting. Among them, the AI ​​driving can collect data by learning the user's driving route and driving behavior. When all the learning is completed, the collected data is screened and checked, and then the full segment of data after screening and checking is automatically transmitted back to the cloud server to execute the construction of the cloud map. The next time you drive and choose the same route, the AI ​​driving will be activated, and the vehicle will be driven to the destination of the route according to the constructed cloud map. Among them, matching and complementing the offline map with the constructed cloud map can improve the accuracy of the map.

[0061] In the above steps S112 to S116 of the present application, when playing the media data of the vehicle, the target sound field area can be determined in response to the touch operation on the display screen. On the basis of determining the media data to be played in the target sound field area, based on the determined media data, the play strategy of the target media player in the target sound field area can be determined, or, on the basis of identifying the physiological state of the target object in the target sound field area, based on the identified physiological state, the play strategy of the target media player in the target sound field area can be determined, and according to the determined above play strategy, the working state of the target media player can be controlled. Since in the embodiment of the present application, the target sound field area can be determined in response to the touch operation on the display screen, on the basis of determining the media data to be played in the target sound field area, or identifying the physiological state of the target object in the target sound field area, the working state of the target media player can be controlled according to the play strategy of the target media player in the determined target sound field area, thereby achieving the purpose of adjusting the play area of ​​the media data, thereby solving the technical problem of poor play experience of the media data of the vehicle, and then achieving the technical effect of improving the play experience of the media data of the vehicle.

If the judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle and the physiological state of the target object is a normal physiological state, the playback strategy can be determined to be the fourth playback strategy, thereby achieving the purpose of determining the playback strategy of the target media playback device and realizing the technical effect of improving the playback experience of the vehicle's media data.

[0089] The method for determining the target sound field area in response to the touch operation on the display screen of this embodiment is further described below.

[0090] As an optional implementation method, step S112, responding to a touch operation on the display screen, determining the target sound field area, includes: responding to the touch operation on the function control set on the display screen to successfully select the target function control, selecting at least one target function control from the function control set, and determining the target sound field area corresponding to the target function control; responding to the failure of the touch operation to select the target function control, determining the current operation information of the touch operation; based on the current operation information, determining the target function control selected from the function control set, and determining the target sound field area corresponding to the target function control.

[0091] In this embodiment, in response to the touch operation on the function control set on the display screen, the target function control is successfully selected, at least one target function control is selected from the function control set, and the target sound field area corresponding to the target function control is determined. Optionally, in response to the touch operation on the function control set, the embodiment successfully selects the target function control, and then completes the selection of at least one target function control from the function control set. From the mapping table of the function control set and the sound field area, the target sound field area corresponding to the selected target function control can be queried, wherein the mapping table may include the mapping relationship between each function control in the function control set and the sound field area.

[0092] In this embodiment, the current operation information may include the operation position and operation time of the touch operation.

[0093] In this embodiment, in response to the failure of the touch operation to select the target function control, the current operation information of the touch operation is determined. Optionally, in response to the failure of the touch operation to select the target function control for the function control set, the embodiment can determine the operation position and operation time in the current operation information of the touch operation, thereby achieving the purpose of determining the operation information of the touch operation, and further achieving the technical effect of improving the positioning accuracy of the operation position.

[0094] In this embodiment, in response to the failure of selecting the target function control by the touch operation, after determining the current operation information of the touch operation, the target function control selected from the function control set is determined based on the current operation information, and the target sound field area corresponding to the target function control is determined. Optionally, based on the determination of the current operation information of the touch operation, the embodiment can determine the target function control selected from the function control set according to the operation position and operation time in the determined current operation information, and can determine the target sound field area corresponding to the target function control. That is to say, in the function control set, according to the operation position of the touch operation performed at the operation time, the target function control selected from the function control set can be determined, and from the mapping table of the function control set and the sound field area, the target sound field area corresponding to the selected target function control can be queried, thereby achieving the purpose of determining the playback area of ​​the media data, and further achieving the technical effect of improving the efficiency of adjusting the playback area of ​​the media data.

[0095] The method for determining a target function control selected from a function control set based on current operation information in this embodiment is further described below.

[0096] As an optional implementation method, based on current operation information, a target function control selected from a function control set is determined, including: in the function control set, determining a function control whose position is less than a distance threshold from the operation position in the current operation information; in response to the sound field area corresponding to the determined function control including at least one object, determining the determined function control as the target function control.

[0097] In this embodiment, the distance threshold may be an initialized threshold or a threshold adjusted according to user needs. For example, the distance threshold may be 1.5 cm, which is only used as an example and is not specifically limited.

[0098] In this embodiment, in response to the failure of the touch operation to select the target function control, after determining the current operation information of the touch operation, in the function control set, a function control whose distance between the position and the operation position in the current operation information is less than a distance threshold is determined. Optionally, based on the determination of the current operation information of the touch operation, this embodiment selects, in the function control set, a function control whose distance from the operation position of the touch operation performed at the above operation time is less than a distance threshold. For example, in the function control set, a function control that is closest to the last operation position on the display screen is selected, thereby achieving the purpose of determining a function control whose distance between the position and the operation position in the current operation information is less than a distance threshold, thereby achieving a technical effect of improving the efficiency of adjusting the playback area of ​​the media data.

[0099] In this embodiment, the above-mentioned object may be a passenger object or a driving object, which is merely an example and not specifically limited here.

[0100] In this embodiment, after determining in the function control set a function control whose distance from a position to an operation position in the current operation information is less than a distance threshold, in response to the fact that the sound field area corresponding to the determined function control includes at least one object, the determined function control is determined as a target function control. Optionally, on the basis of determining the function control, this embodiment detects whether the sound field area corresponding to the determined function control includes an object, and if it is detected that the sound field area corresponding to the function control includes an object, the determined function control is determined as a target function control selected from the function control set, thereby achieving the purpose of determining the target function control, and further achieving the technical effect of improving the efficiency of adjusting the playback area of ​​the media data.

[0101] In an embodiment of the present invention, when playing the media data of the vehicle, the target sound field area can be determined in response to the touch operation on the display screen. On the basis of determining the media data to be played in the target sound field area, based on the determined media data, the play strategy of the target media playback device in the target sound field area can be determined, or, on the basis of identifying the physiological state of the target object in the target sound field area, based on the identified physiological state, the play strategy of the target media playback device in the target sound field area can be determined, and according to the determined above-mentioned play strategy, the working state of the target media playback device can be controlled. Since in the embodiment of the present application, the target sound field area can be determined in response to the touch operation on the display screen, on the basis of determining the media data to be played in the target sound field area, and / or identifying the physiological state of the target object in the target sound field area, the working state of the target media playback device can be controlled according to the play strategy of the target media playback device in the determined target sound field area, thereby achieving the purpose of adjusting the playback area of ​​the media data, thereby solving the technical problem of poor playback experience of the vehicle's media data, and then achieving the technical effect of improving the playback experience of the vehicle's media data.

[0102] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0103] At present, when playing media data in a vehicle, due to different user requirements for playback, users have different required areas for playing media data. However, in the related technology, only the playback sound effect and playback volume of the media data can be adjusted, which leads to the technical problem of poor playback effect of the media data in the vehicle.

[0104] However, an embodiment of the present invention proposes a method for playing media data of a vehicle, and when playing the media data of the vehicle, a target sound field area can be determined in response to a touch operation on a display screen. On the basis of determining the media data to be played in the target sound field area, a playback strategy of a target media playback device in the target sound field area can be determined based on the determined media data, or, on the basis of identifying the physiological state of the target object in the target sound field area, a playback strategy of a target media playback device in the target sound field area can be determined based on the identified physiological state, and according to the determined playback strategy, the working state of the target media playback device can be controlled, thereby achieving the purpose of adjusting the playback area of ​​the media data, thereby solving the technical problem of poor playback experience of the vehicle's media data, and further achieving the technical effect of improving the playback experience of the vehicle's media data.

[0105] In this embodiment, the above-mentioned sound field area can be as shown in Figure 2(a). For example, Figure 2(a) is a schematic diagram of the sound field area of ​​a vehicle according to an embodiment of the present invention. As shown in Figure 2(a), the sound field area of ​​the vehicle is divided to obtain the main driver sound field area, the co-driver sound field area, the second row left sound field area, the second row right sound field area, the third row left sound field area and the third row right sound field area of ​​the vehicle. Among them, the main driver sound field area, the co-driver sound field area, the second row left sound field area, the second row right sound field area, the third row left sound field area and the third row right sound field area can be simulated respectively through the circles of each area shown in Figure 2(a).

[0106] In this embodiment, media data can be played by using a media player in each of the sound field areas obtained by division, wherein the media player can be at least one of the following devices: a sound system and a loudspeaker, etc., which are only used as examples and are not specifically limited.

[0107] In this embodiment, if the user wants to control the sound field during driving, but slides the touch button and does not slide to the target position (for example, the slide is crooked or the slide is interrupted), then in the touch button set, a touch button whose distance between the position and the sliding position in the current sliding operation information is less than the distance threshold is determined, and in response to the sound field area corresponding to the determined touch button including at least one passenger object / driving object, the above-determined touch button is determined as the target touch button selected from the touch button set. After determining the target touch button selected from the touch button set, an inquiry message is sent to the user, wherein the inquiry message can be used to inquire the user whether the target sound field area corresponding to the target touch button is the sound field area that the user wants to adjust. If the target sound field area corresponding to the target touch button is not the sound field area that the user wants to adjust, the target sound field area corresponding to the target touch button is automatically calibrated to the sound field area that the user wants to adjust. The above-mentioned sound field area that the user wants to adjust can also be called the optimal sound field area.

[0108] In this embodiment, if the dotted circle is placed at the gray circle, the sound effect of playing the media data in the sound field area corresponding to the gray circle is better than the sound effect of playing the media data in the sound field areas corresponding to other gray circles. For example, if the current playback requirement is that the sound effect of playing the media data in the sound field areas of the entire vehicle is the same, the dotted circle can be placed at the gray circle in the middle of the vehicle; if the current playback requirement is that the sound effect of playing the media data in the sound field area corresponding to the left seat in the third row is better than the sound effect of playing the media data in the sound field areas corresponding to other seats, the dotted circle can be placed at the gray circle corresponding to the left side of the third row.

[0109] Optionally, a detection device of the vehicle can be used to detect whether the sound field area corresponding to the touch button includes at least one passenger object / driving object. The detection device can be at least one of the following devices: a camera, a camera, and a seat sensor, etc., which are only used as examples and are not specifically limited.

[0110] In this embodiment, if during driving, in response to a touch operation on a function control set, at least one target function control is selected from the function control set, and a target sound field area corresponding to the target function control is determined. The position of the determined target sound field area in the vehicle is judged to obtain a judgment result. If the obtained judgment result indicates that the target sound field area is located in the driving area of ​​the vehicle, the playback strategy can be determined according to the media type of the media data. In other words, if the judgment result indicates that the target sound field area is located in the driving area of ​​the vehicle, and the media type of the media data is a first media type, the playback strategy can be determined to be a first playback strategy, and according to the determined first playback strategy, the target media playback device can be prohibited from playing media data in the driving area. For example, if the judgment result indicates that the target sound field area is located in the driving area of ​​the vehicle, and the media type of the media data is a video type, the playback strategy can be determined to be a first playback strategy, and according to the determined first playback strategy, the speaker can be prohibited from playing videos in the driving area. In other words, the sound field area is switched to the rear sound field area, and the speaker is controlled to play the video in the rear sound field area. Among them, the rear row sound field area can include: the second row left sound field area, the second row right sound field area, the third row left sound field area and the third row right sound field area.

[0111] In this embodiment, if the judgment result indicates that the target sound field area is located in the driving area of ​​the vehicle, and the media type of the media data is the second media type, the playback strategy can be determined to be the second playback strategy, and according to the determined second playback strategy, the target media playback device can be allowed to play the media data in the driving area. For example, if the judgment result indicates that the target sound field area is located in the driving area of ​​the vehicle, and the media type of the media data is an audio type / document type, the playback strategy can be determined to be the second playback strategy, and according to the determined second playback strategy, the speaker can be allowed to play audio / document in the driving area.

[0112] In this embodiment, if during driving, in response to a touch operation on a function control set, at least one target function control is selected from the function control set, and the target sound field area corresponding to the target function control is determined. The position of the determined target sound field area in the vehicle is judged to obtain a judgment result. If the obtained judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle, the playback strategy can be determined according to the physiological state of the target object. In other words, if the judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle, and the physiological state of the target object is an abnormal physiological state, the playback strategy can be determined to be a third playback strategy, and according to the determined third playback strategy, the target media playback device can be prohibited from playing media data in the passenger area. For example, if the judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle, and the physiological state of the target object is a sleeping state, the playback strategy can be determined to be a third playback strategy, and according to the determined third playback strategy, the speaker can be prohibited from playing video / audio / documents in the passenger area.

[0113] In this embodiment, if the judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle, and the physiological state of the target object is a normal physiological state, the playback strategy can be determined to be the fourth playback strategy, and according to the determined fourth playback strategy, the target media playback device can be allowed to play media data in the passenger area. For example, if the judgment result indicates that the target sound field area is located in the passenger area of ​​the vehicle, and the physiological state of the target object is a sober state, the playback strategy can be determined to be the fourth playback strategy, and according to the determined fourth playback strategy, the speaker can be allowed to play video / audio / documents in the passenger area.

[0114] In this embodiment, the server can transmit media data to the vehicle in response to a download request from the vehicle. For example, FIG2(b) is a schematic diagram of data interaction between a vehicle and a server according to an embodiment of the present invention. As shown in FIG2(b), the server 221 can transmit media data to the vehicle 220 in response to a download request from the vehicle 220.

[0115] In this embodiment, in response to a sliding operation on the display screen of the vehicle, at least one target touch key in a selected state can be determined from the touch key set. In response to at least one target touch key being in a selected state, a target sound field area corresponding to the target touch key can be determined, and according to the determined playback strategy, the working state of the target media playback device in the target sound field area can be controlled, thereby achieving the purpose of adjusting the playback area of ​​the media data, thereby solving the technical problem of poor playback experience of the vehicle's media data, and further achieving the technical effect of improving the playback experience of the vehicle's media data.
