DETAILED DESCRIPTION

[0044] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0045] Figure 1 FIG is a schematic flow chart of a method for controlling an ambient light of a vehicle according to an embodiment of the present invention. Figure 1As shown, in this embodiment, the vehicle includes at least one ambient light, each of which includes a plurality of lamp beads. The ambient light control method for the vehicle includes the following steps:

[0046] Step S100: periodically acquiring an audio digital signal from the in-vehicle entertainment system and converting the audio digital signal into a frequency domain signal; here, the audio digital signal is acquired at a preset time interval, and the preset time interval is any value in the range of 20ms to 40ms, for example, 20ms, 30ms, or 40ms;

[0047] Step S200, extracting a plurality of preset frequency bands from the frequency domain signal, and obtaining a decibel value corresponding to each preset frequency band;

[0048] Step S300, adjusting the decibel value corresponding to each preset frequency band using the adjustment parameter to obtain a corresponding adjusted decibel value;

[0049] Step S400: adjusting the brightness of the multiple lamp beads of each atmosphere lamp according to the adjusted decibel values ​​of the multiple preset frequency bands.

[0050] This embodiment adjusts each preset frequency band by adjusting parameters, that is, reasonably adjusting the relative relationship between multiple preset frequency bands, thereby widening the gap between multiple preset frequency bands, so that the change amplitude of the ambient light brightness can match the constantly changing audio, thereby improving the user's immersion.

[0051] In this embodiment, the digital audio signal includes music and speech. For music, six preset frequency bands are selected from the music, with the six preset frequency bands forming a set that increases in frequency from bass to treble to accommodate various musical styles. For speech, two preset frequency bands are selected from the speech. In other embodiments, the number of preset frequency bands can be set based on specific design requirements.

[0052] In step S300, each preset frequency band corresponds to an adjustment parameter. Table 1 is a comparison table of adjustment parameters corresponding to the six preset frequency bands of music. Table 2 is a comparison table of adjustment parameters corresponding to the two preset frequency bands of speech.

[0053] Table 1

[0054]

[0055] Table 2

[0056]

[0057] In this embodiment, the adjustment parameter is less than or equal to 3. For music, the adjustment parameter is less than or equal to 1. For example, the adjustment parameters corresponding to the six preset frequency bands of music can be set to 0.3, 0.6, 0.6, 0.8, 1, and 1, respectively. For speech, the adjustment parameter is less than or equal to 3 and greater than or equal to 1. For example, the adjustment parameters corresponding to the two preset frequency bands of speech can be set to 3 and 2, respectively. In other embodiments, the adjustment parameter can also be set according to specific design requirements.

[0058] Figure 2 FIG is a schematic flow chart of a method for controlling an ambient light of a vehicle according to another embodiment of the present invention. Figure 2 As shown, in this embodiment, step S400 specifically includes the following steps:

[0059] Step S410, selecting the maximum value among the adjusted decibel values ​​of multiple preset frequency bands as the target decibel value;

[0060] Step S420: adjusting the brightness of the multiple lamp beads of each ambient light according to the target decibel value.

[0061] For example, for music, if the maximum adjusted decibel value among the six preset frequency bands corresponds to frequency number 3, then this maximum value is used as the target decibel value. Here, if a preset frequency band does not appear in a certain time period among the six preset frequency bands, the decibel value corresponding to the preset frequency band is set to zero.

[0062] In this embodiment, step S420 specifically includes the following steps:

[0063] Step S421, searching a preset comparison table for a target brightness value corresponding to the target decibel value according to the target decibel value;

[0064] Step S422: When the target brightness value is not zero, the brightness of the multiple lamp beads of each atmosphere lamp is adjusted according to the target brightness value, the preset maximum brightness value, and the number of lamp beads of each atmosphere lamp.

[0065] This embodiment can adjust the brightness of the atmosphere lamp according to the number of lamp beads of each atmosphere lamp, so no matter how many lamp beads the atmosphere lamp has, the brightness of the atmosphere lamp can be reasonably adjusted so that the change amplitude of the brightness of each atmosphere lamp matches the constantly changing audio.

[0066] Figure 3 FIG is a schematic flow chart of a method for controlling an ambient light of a vehicle according to another embodiment of the present invention. Figure 3 As shown, in this embodiment, step S422 includes the following steps:

[0067] Step S4221: grouping each ambient light according to the preset maximum brightness value and the number of lamp beads of each ambient light to obtain the number of groups of each ambient light and the brightness value range of each group;

[0068] Step S4222, comparing the target brightness value with the brightness value range of each group of each atmosphere light to obtain a comparison result;

[0069] Step S4223: Adjust the brightness of the multiple lamp beads of each atmosphere lamp according to the comparison result.

[0070] In this embodiment, the target decibel value is positively correlated with the target brightness value, that is, the larger the target decibel value, the larger the target brightness value, and the smaller the target decibel value, the smaller the target brightness value.

[0071] In this embodiment, for example, the preset maximum brightness value is 15, and the serial numbers 0 to 15 are taken. The target brightness value is any value in the serial numbers 0 to 15. If the number of lamp beads of a certain atmosphere lamp is 3, the atmosphere lamp is grouped and divided into 3 groups, wherein each group has one lamp bead, the first lamp bead corresponds to serial numbers 1 to 5, that is, the brightness value range is 1 to 5, the second lamp bead corresponds to serial numbers 6 to 10, and the third lamp bead corresponds to serial numbers 10 to 15. When the target brightness value is 6, it falls within the serial number range corresponding to the second lamp bead, so the first and second lamp beads are both on, and the third lamp bead is off. When the target brightness value is 11, it falls within the serial number range corresponding to the third lamp bead, so the first, second and third lamp beads are all on. If the number of lamp beads of a certain atmosphere lamp is 6, the atmosphere lamp is divided into 6 groups, and 15 divided by 6 is 2.5. So each group has one lamp bead, the first lamp bead corresponds to serial numbers 1 to 2.5, the second lamp bead corresponds to serial numbers 2.5 to 5, the third lamp bead corresponds to serial numbers 5 to 7.5, the fourth lamp bead corresponds to serial numbers 7.5 to 10, the fifth lamp bead corresponds to serial numbers 10 to 12.5, and the sixth lamp bead corresponds to serial numbers 12.5 to 15. When the target brightness value is 6, it falls within the serial number range corresponding to the third lamp bead, so the first, second, and third lamp beads are all on, and the fourth, fifth, and sixth lamp beads are all off. When the target brightness value is 11, it falls within the serial number range corresponding to the fifth lamp bead, so the first, second, third, fourth, and fifth lamp beads are all on, and the sixth lamp bead is off, so that each atmosphere light has a consistent rhythm, enhancing the user's immersion.

[0072] In this embodiment, step S421 further includes the following steps:

[0073] Step 1: When the target brightness value is zero, adjust the brightness of the multiple lamp beads of each ambient light according to the preset lamp bead fallback table. Table 3 is the lamp bead fallback table for the main passenger ambient light, and Table 4 is the lamp bead fallback table for the passenger passenger ambient light.

[0074] Table 3

[0075]

[0076] Table 4

[0077]

[0078] In this embodiment, step one specifically includes the following steps:

[0079] The brightness of multiple lamp beads of each atmosphere light is lowered in turn according to the duration that the target brightness value remains at zero.

[0080] For example, when a certain ambient light in the main driver's seat ambient light includes 11 lamp beads, within the previous 20ms, all 11 lamp beads are lit. If the target brightness value is zero in the next 20ms, the lamp beads are extinguished according to the lamp bead fallback table in Table 3, that is, the 11th lamp bead is directly extinguished. Next, if the target brightness value is zero for a period of time, the 10th lamp bead is directly extinguished at 40ms, the 9th lamp bead is directly extinguished at 60ms, and the remaining lamp beads are extinguished in sequence. When a certain ambient light in the main driver's seat ambient light includes 7 lamp beads, within the previous 20ms, all 7 lamp beads are lit. If the target brightness value is zero in the next 20ms, the lamp bead fallback table in Table 3 is extinguished, that is, the 7th lamp bead is directly extinguished. If the target brightness value remains at zero for a period of time, the sixth lamp will be turned off immediately after 40ms, followed by the remaining lamps. Here, 20%, 40%, 50%, 60%, 80%, and 100% represent the brightness values. In other words, after the sixth lamp is turned off, the fifth lamp will not be turned off immediately, but will adjust its brightness. This process is repeated so that the lamps follow the rhythm of the music, creating a visual display. Similarly, the passenger ambient light is turned off according to Table 4.

[0081] Figure 4 FIG. 1 is a schematic block diagram of a vehicle ambient light control system according to an embodiment of the present invention. Figure 4As shown, in this embodiment, the ambient light control system 100 for a vehicle includes a control module 10, and the control module 10 includes a memory 11 and a processor 12. The memory 11 stores a calculation program, and when the calculation program is executed by the processor, it is used to implement the above-mentioned ambient light control method. The processor 12 can be a central processing unit (CPU), or a digital processing unit, etc. The processor 12 sends and receives data through a communication interface. The memory 11 is used to store the program executed by the processor 12.

Here, the control module 10 can be a vehicle body controller.

[0082] For the purposes of the description of this embodiment, a "computer-readable medium" can be any device that can contain, store, communicate, propagate, or transmit a program for use with an instruction execution system, device, or apparatus, or in conjunction with such instruction execution systems, devices, or apparatuses.

In addition, the computer-readable medium can even be paper or other suitable medium on which the program can be printed, since the program can be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, deciphering, or processing in other suitable ways as necessary, and then stored in the computer memory 11.
