The embodiment of the present application is not particularly limited, and a person skilled in the art may select the learning model according to an actual usage scenario.
As an alternative embodiment, each set of data in the plurality of sets of music data includes: the music data comprises sample music data and music type labels of the music data, wherein the music type labels have a preset association relation with playing volume. It is to be noted that the sample music data is previously acquired by the history data acquisition. The music type label of the music data is obtained by means of labeling. Preferably, a preset association relationship is set between the music type tag and the playing volume. For example, the music type tag is pop music, and the corresponding playing volume is middle. The music type label is classical music, and the corresponding playing volume is small.
In step S203, when the vehicle-mounted terminal is running the first application and the second application runs in the background, the playing volume of the first application is dynamically adjusted according to the detection result of the music played by the second application. It is understood that the first application is a navigation-type application running on the in-vehicle terminal. The detection result of the played music of the second application program means that the music belongs to a preset type.
It should be noted that, as an alternative implementation, the first application program is running at the vehicle-mounted terminal, and the second application program runs in the background. That is, the first application program is running and displayed on the main interface of the vehicle-mounted terminal, i.e., the navigation service is performed, and the second application program is running in the background and playing music.
As an alternative embodiment, the playing volume of the first application program may be dynamically adjusted by gradually decreasing or increasing the volume.

It can be understood that the first application program has a navigation information playing volume in the background navigation process, and the navigation information playing volume at this time needs to be adjusted according to the detection result of the music played by the second application program. The process of adjusting may include: increasing/decreasing the playing volume of the navigation information while maintaining the playing volume of a second application program; or keeping the playing volume of the navigation information and keeping the playing volume of the second application program.
As a preferable preference in this embodiment, the dynamically adjusting the playing volume of the first application according to the detection result of the played music of the second application includes: under the condition that the detection result of the played music of the second application program is a first music type, dynamically adjusting the current playing volume of the first application program to be a first playing volume; under the condition that the detection result of the played music of the second application program is a second music type, dynamically adjusting the current playing volume of the first application program to be a second playing volume; under the condition that the detection result of the played music of the second application program is a third music type, dynamically adjusting the current playing volume of the first application program to be a third playing volume; the third playing volume > the second playing volume > the first playing volume, and the first music type, the second music type and the third music type all comprise preset playing volumes corresponding to different music types.
In specific implementation, when the detection result of the played music of the second application program is the first music type, the current playing volume of the first application program is dynamically adjusted to be the first playing volume, that is, the current playing volume of the first application program is dynamically adjusted to be the first playing volume according to the first music type. It can be understood that, when the detection result of the played music of the second application program is a second music type, the current playing volume of the first application program is dynamically adjusted to be a second playing volume; and dynamically adjusting the current playing volume of the first application program to be a third playing volume under the condition that the playing music detection result of the second application program is a third music type. The third playback volume > the second playback volume > the first playback volume. For example, the playing volume includes high, medium, low, medium, high, and balanced.
It can be understood that the first music type, the second music type, and the third music type all include preset playing volume sizes corresponding to different music types, which means that the first music type, the second music type, and the third music type all have different corresponding preset playing volume sizes (decibels). And meanwhile, dynamically adjusting the current playing volume according to the preset playing volume.
In addition, the third playing volume, the second playing volume and the first playing volume can also consider the influence of the current environmental noise in the vehicle. For example, Va playback volume is Vb threshold volume ± Vc ambient noise.

That is, when the current playing volume of the second application does not affect the first application, no adjustment is needed.
Further, when the current playing volume of the second application program is higher than a preset threshold, the playing volume of the first application program is adjusted to be not higher than the preset threshold. It is noted that the preset threshold is determined by the volume of sound in the vehicle environment. That is, when the current playing volume of the second application affects the playing volume of the first application, the playing volume of the first application needs to be adjusted and cannot be higher than the preset threshold. When the environment in the vehicle is noisy and the playing volume of the second application program is high, the playing volume of the first application program needs to be correspondingly adjusted (increased), but the environment in the vehicle is not disturbed.
