The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

Referring to fig. 1, in order to enable the visual effect of the atmosphere lamp in the vehicle to change along with the rhythm of the music when the vehicle-mounted infotainment system plays the music, so as to avoid monotonous and uninteresting people in the vehicle and improve the experience of listening to songs in the vehicle, the embodiment provides a method for adjusting the atmosphere lamp in the vehicle based on the rhythm of the music, which comprises the following steps:
s11: the method comprises the steps of obtaining an audio signal when music is played, and converting the audio signal from a time domain signal to a frequency domain signal.
It should be noted that the music in this embodiment may be not only pure music in the format of MP3, WMA, MIDI, etc., but also music in video files in the format of AVI, RMVB, RM, etc. This step acquires the audio signal of the music being played in real time and converts the audio signal from the time domain to the frequency domain, preferably using a Fast Fourier Transform (FFT) algorithm.
S12: and selecting the frequency domain signals with the same number as the number of the atmosphere lamps in the vehicle from all the frequency domain signals, and enabling each selected frequency domain signal to correspondingly control one atmosphere lamp in the vehicle.
Since the conversion of an audio signal from the time domain to the frequency domain may result in thousands of superimposed frequency domain signals, this step randomly selects several of the thousands of frequency domain signals to control the interior atmosphere lamp accordingly. Of course, in other embodiments, those skilled in the art may establish other criteria for screening the frequency domain signals, and select a high quality frequency domain signal from thousands of frequency domain signals to control the interior atmosphere lamp accordingly.
S13: and matching the frequency parameter of each selected frequency domain signal with each preset frequency parameter interval.
It should be noted that, before the method of the present embodiment is executed, the in-vehicle infotainment system (vehicle) executing the method reads a mechanism file pre-stored by itself or stored in an external storage device, where the mechanism file includes a plurality of preset frequency parameter intervals and a color state of the vehicle interior atmosphere lamp corresponding to each preset frequency parameter interval, as shown in table 1:
TABLE 1
It should be noted that the data and colors in table 1 are only used as an illustration, and in other embodiments, those skilled in the art can set themselves according to actual needs.
The step of respectively matching the frequency parameters of the frequency domain signals with the preset frequency parameter intervals specifically includes: the frequency values of the selected frequency domain signals are respectively matched with the intervals of 20 HZ-200 HZ, 200 HZ-2000 HZ, 2000 HZ-20000 HZ and the like so as to judge which preset frequency parameter interval the frequency values belong to. For example, assuming that the frequency value of the selected frequency domain signal is 300HZ, the matching result indicates that the predetermined frequency parameter interval successfully matched with 300HZ is "200 HZ to 2000 HZ".
S14: and generating an atmosphere lamp control signal in the vehicle according to the color state of the atmosphere lamp in the vehicle corresponding to the successfully matched preset frequency parameter interval.
In step S13, for example, the color status of the interior atmosphere lamp corresponding to the interval "200 HZ to 2000 HZ", that is, "yellow", is first found, and then a control signal for adjusting the corresponding interior atmosphere lamp to display yellow is generated.
S15: and sending the vehicle interior atmosphere lamp control signal to a corresponding vehicle interior atmosphere lamp for the vehicle interior atmosphere lamp to adjust the display color according to the vehicle interior atmosphere lamp control signal.
In detail, the in-vehicle infotainment system transmits the generated control signal to the corresponding in-vehicle atmosphere lamp through the CAN protocol.

s21: and for each selected frequency domain signal, matching the amplitude parameter of the selected frequency domain signal with each preset amplitude parameter interval corresponding to the successfully matched preset frequency parameter interval.
It should be noted that the step of matching the amplitude parameter of the frequency domain signal with each of the preset amplitude parameter intervals is performed on the basis of determining the preset frequency parameter interval to which the frequency domain signal belongs, for example, for the frequency domain signal whose frequency value is determined to belong to the interval "20 HZ to 200 HZ", the step of matching the amplitude value of the frequency domain signal with the intervals "10A to 200A", "201A to 400A", and the like, respectively, to determine which preset amplitude parameter interval the amplitude value belongs to. Assuming that the amplitude value of the frequency domain signal is 50A, the preset amplitude parameter interval successfully matched with 50A is found to be 10A-200A after matching.
S22: and generating an atmosphere lamp control signal in the vehicle according to the light and shade state of the atmosphere lamp in the vehicle corresponding to the successfully matched preset amplitude parameter interval and the color state of the atmosphere lamp in the vehicle corresponding to the successfully matched preset frequency parameter interval.
In connection with the example of steps S14 and S21, this step first finds the bright-dark state, i.e., "bright", of the interior atmosphere lamp corresponding to the section "10A to 200A", and then generates a control signal for adjusting the corresponding interior atmosphere lamp to display yellow and have bright brightness.

Assuming that the volume value of the frequency domain signal is 30dB, the matching result shows that the preset volume parameter interval successfully matched with 30dB is 10 dB-50 dB.
