[0067] In order to improve the rhythm control of the in-vehicle atmosphere lamp while reducing the amount of data processing in the later stage, so as to reduce the control burden of the in-vehicle control system and improve driving safety, this embodiment discloses an in-vehicle atmosphere lamp rhythm control method for an atmosphere lamp controller independent of the vehicle central control system. The atmosphere lamp controller is connected to the atmosphere lamp driving board to provide an atmosphere lamp control signal to the atmosphere lamp driving board, so that the atmosphere lamp drives the in-vehicle atmosphere lamp to rhythmically emit light.

[0068] Please refer to Figure 1 , which is a schematic structural diagram of an in-vehicle atmosphere lamp rhythm control system disclosed in this embodiment. The atmosphere lamp controller 1 is independent of the vehicle central control system, that is, the control work of the atmosphere lamp controller 1 is independent of that of the central control system, thus avoiding occupying the control resources of the central control system. In this embodiment, the atmosphere lamp controller 1 has a data operation function; after calculating the control signal, the atmosphere lamp controller 1 will provide an atmosphere lamp control signal to the atmosphere lamp driving board 2, so that the atmosphere lamp driving board 2 drives the in-vehicle atmosphere lamp 3 to rhythmically emit light; in this embodiment, the in-vehicle atmosphere lamp 3 can be realized by RGB light-emitting diodes, and it follows the played music to rhythmically emit light through different frequencies of on and off, different brightnesses, and / or lighting colors; the atmosphere lamp driving board 2 and the in-vehicle atmosphere lamp 3 can be detachably connected or fixedly connected.

[0069] Please refer to Figure 2 , which is a schematic flowchart of an in-vehicle atmosphere lamp rhythm control method disclosed in this embodiment for the atmosphere lamp controller 1. The in-vehicle atmosphere lamp rhythm control method includes: step S100, step S200, step S300, step S400, and step S500, where:

[0070] Step S100, obtain the original audio signal in the time domain and perform frequency-domain conversion to obtain the frequency-domain signal. In this embodiment, the so-called original audio signal represents the music currently being played. The acquisition of the original audio signal can be achieved by collecting through a microphone, or by receiving the signal sent by the mobile terminal. Specifically:

[0071] In one embodiment, please refer to Figure 1 , in step S100, collect the music currently being played through the microphone 4 to obtain the original audio signal. The music currently being played can be the music played by the in-vehicle speaker, the music played by the mobile terminal, or the singing of the user. Of course, it can also be a combination of the above sound sources, that is, as long as it can be collected by the microphone 4.

[0072] In another embodiment, please refer to Figure 1 , the ambient light controller 1 performs data interaction with the mobile terminal 5. In step S100, receive the audio data sent by the mobile terminal to obtain the original audio signal. In this embodiment, the in-vehicle user can play music through the mobile terminal 5, and the mobile terminal 5 directly transmits the currently played music to the ambient light controller 1 through communication. Specifically, the data interaction between the ambient light controller 1 and the mobile terminal 5 can be wired or wireless. The mobile terminal 5 can be, for example, a mobile phone, a tablet or a music player, etc., as long as the mobile terminal can play music and can perform data interaction with the ambient light controller 1. As an optional embodiment, the mobile terminal 5 can have the function of installing application software to analyze the data transmitted by the ambient light controller 1, such as big data analysis.

[0073] Step S200, obtain the frequency, amplitude and lyric information of the music currently being played based on the original audio signal. In a specific embodiment, when the original audio signal is obtained in step S100, the original audio signal can be converted into a digital format audio signal. Of course, when the signal sent by the mobile terminal is received, it is already digital music and does not need to be converted from analog to digital. In this embodiment, after performing frequency-domain conversion on the original audio signal to obtain the frequency-domain signal, the acoustic characteristics of the corresponding music, such as frequency, amplitude, etc., can be identified, or the lyric information can be extracted based on the speech recognition technology. In this embodiment, by extracting the lyric information, the category or style of the music currently being played can be better known, so as to provide a more accurate reference for the rhythm control. In this embodiment, the music style can be rock, blues, classical, etc., and the current music style can be comprehensively determined by the acoustic characteristics, lyric information and the instruments used.

[0074] Step S300: Obtain a historical control signal sequence corresponding to the currently playing music based on the frequency, amplitude, and lyric information of the currently playing music. In this embodiment, the so-called historical control signal sequence refers to the historical atmosphere light control signals generated for the same piece of music. Specifically, for the currently playing music, previously, the user has played this music, and the atmosphere light controller has performed rhythm control on the in-vehicle atmosphere lights based on this music. That is, previously, atmosphere light control signals have been generated for this music, and the collection of atmosphere light control signals corresponding to this music is the historical control signal sequence. In the specific implementation process, the historical control signal sequence can be iteratively updated over time. That is, the corrected control signals for the subsequent play replace the control signals for the previous play. Thus, the historical control signal sequence becomes more and more matched to the playing music.

[0075] In this embodiment, by obtaining the historical control signal sequence corresponding to the currently playing music, it is not necessary to recalculate the control signals every time music is played, reducing the computational load. Moreover, since the historical control signal sequence is iteratively updated, the atmosphere light control signals can become more and more matched to the playing music.

[0076] Step S400: Adjust the historical control signal sequence based on the frequency, amplitude, and lyric information of the currently playing music to obtain the current atmosphere light control signal. In this embodiment, after obtaining the historical control signal sequence corresponding to the currently playing music, it is only necessary to make corresponding adjustments based on the frequency, amplitude, and lyric information of the currently playing music on the basis of the historical control signal sequence to obtain the current atmosphere light control signal. Specifically, during the process of playing music historically, there may be environmental factors such as noise interfering with the music at that time. Therefore, the historical control signals may have factors that do not match the current environment. Thus, the frequency, amplitude, and lyric information of the currently playing music can be used to adjust the historical control signal sequence, so as to obtain an atmosphere light control signal that is more matched to the current environment.

[0077] Step S500: Output the current ambient light control signal to the ambient light driver board, so that the ambient light driver board drives the in-vehicle ambient light to emit rhythmically, making the brightness and on / off frequency of the in-vehicle ambient light match the rhythm of the currently playing music, and making the color of the in-vehicle ambient light correspond to the category to which the currently playing music belongs. The category of music can be classical, pop, rock, jazz, etc., and this category can be set according to actual needs. In this embodiment, the in-vehicle ambient light can be an RGB light-emitting diode. Driven by the ambient light driver board, the in-vehicle ambient light can generate colors that match the style of the currently playing music. For example, classical corresponds to green, pop and rock correspond to red, jazz corresponds to blue, etc. Of course, the corresponding relationship of colors can be changed according to actual needs; the brightness and on / off frequency of the in-vehicle ambient light match the rhythm of the currently playing music, that is, the in-vehicle ambient light is turned on and off following the music beat.

[0078] In order to update the ambient light control signal and enable the ambient light controller to learn the currently playing music, in a specific embodiment, after step S400, it further includes:

[0079] Step S610: Generate a current ambient light control signal sequence based on the current ambient light control signal, where each control signal in the current ambient light control signal sequence is in one-to-one matching correspondence with the currently playing music in the time domain; Step S620: Iteratively update the current ambient light control signal sequence with the historical control signal sequence to obtain a new historical control signal sequence for use when the in-vehicle ambient light rhythm control method is executed next time.

[0080] In this embodiment, by iteratively updating the historical control signal sequence, the ambient light controller can better learn and accumulate the ambient light control signals corresponding to the currently playing music, so that the ambient light control signals increasingly match the currently playing music, and in the process of generating control signals based on this music subsequently, it can be fast and accurate.

[0081] In a specific embodiment, the in-vehicle ambient light rhythm control method is implemented based on a neural network. After step S200, it further includes: extracting the acoustic features of the currently playing music from the original audio signal; determining the classification label of the currently playing music based on the acoustic features; sending the classification label to the mobile terminal to determine the user's interest type. Specifically, the category of music can be classical, pop, rock, jazz, etc., and this category can be set according to actual needs. In this embodiment, by extracting the lyric information, the category or style of the currently playing music can be better known, so as to provide a more accurate reference for rhythm control. In this embodiment, the music style can be rock, blues, classical, etc., and the current music style can be comprehensively determined through acoustic features, lyric information, and the musical instruments used.

[0082] In an optional embodiment, to reduce the influence of environmental factors on the rhythm control of in-vehicle ambient lights, the in-vehicle ambient light rhythm control method further includes:

[0083] Step S710, receiving audio modulation parameters sent by a mobile terminal; Step S720, modulating the original audio signal according to the audio modulation parameters to obtain a modulated audio signal, where the modulation method includes extracting or filtering specified instrument signals and / or allocating noise reduction gains; during the execution of steps S200 to S500, the modulated audio signal is processed as the original audio signal. In this embodiment, configuring the audio modulation parameters by using the mobile terminal can make the rhythm control of the in-vehicle ambient lights more targeted and better match the current user's usage preferences. Specifically:

[0084] The modulation method can be to extract or filter specified instrument signals. For example, only the sound of the piano is retained while the sound of the violin is filtered out;

[0085] The modulation method can also be to increase the gain for high notes and decrease the gain for low notes, so that the effect presented by the ambient lights better matches the musical rhythm;

[0086] For the audio signal received by the mobile terminal, when the transmitted music is a live concert, the modulation method can also be to filter out the shouts of the audience at the concert site, so that the rhythm control better matches the song itself;

[0087] In the scenario of a combination of collecting human voices through the microphone 4 and receiving music transmitted by the mobile terminal, the modulation parameters can be used to filter out the sound of the microphone or the ambient noise collected by the microphone, so that the rhythm control can better match the music itself and reduce the influence of ambient sounds or the user's out-of-tune singing.

[0088] This embodiment also discloses an in-vehicle ambient light rhythm control device for an ambient light controller independent of the vehicle central control system.

[0112] According to an in-vehicle ambient light rhythm control method, device and system disclosed in an embodiment of the present invention, after obtaining an original audio signal in the time domain and performing frequency domain conversion to obtain a frequency domain signal, a historical control signal sequence corresponding to the currently playing music is obtained based on the frequency, amplitude and lyrics information of the currently playing music, and the historical control signal sequence is adjusted to obtain the current ambient light control signal.

Therefore, on the one hand, the current ambient light control signal can be obtained quickly, the response speed can be improved, the data processing volume can be reduced, and thus the control burden of the in-vehicle control system can be reduced; on the other hand, since the current ambient light control signal is iteratively obtained based on the historical ambient light control signal, the current ambient light control signal can be corrected specifically, so that the current ambient light control signal can better match the currently playing music, making the rhythm of the in-vehicle ambient light more matching with the music rhythm, and the color of the in-vehicle ambient light more corresponding to the currently playing music, thereby further improving the rhythm of the in-vehicle ambient light and then improving the user experience. Since the control burden of the in-vehicle control system is reduced and the user experience is improved, the driving experience of the driver will be improved and the driving safety problem will be reduced.
