[0043] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0044] Embodiment 1, Figure 1 The flowchart of one embodiment of the vehicle ambient light control method provided by the present invention is shown, and the method is executed by a first controller. Preferably, the first controller is an intelligent cockpit controller. Figure 1 As shown, the method comprises the following steps:

[0045] Step 110: receiving a music playing request from the user, and determining whether the ambient light meets the start-up conditions of the music rhythm mode.

[0046] In some embodiments of the present invention, the user issues music playback instructions to the vehicle central control in a variety of ways, so that the vehicle central control sends the user's music playback request to the smart cockpit controller. Exemplarily, the user connects the hard disk drive (HDD) storing the music files to the vehicle playback device using the USB interface; or the playback device (such as a mobile phone, tablet computer) and the receiving device (vehicle playback device) need to be paired by Bluetooth. After the pairing is successful, the playback device sends the music signal to the receiving device wirelessly to play the Bluetooth music in the mobile phone in the car; or the corresponding music playback software is installed in the vehicle central control, and the online music data is transmitted from the server to the user's playback device through the network. The user issues a music playback instruction to play the music in the hard disk drive, online music or Bluetooth music by manually clicking on the music player interface of the target display or by voice control.

[0047] Specifically, the vehicle central control is connected to a target display (central control screen) and a target amplifier. After receiving a user's music play request, the smart cockpit controller controls the target display connected to the vehicle central control to display a music player interface with a cover image; and obtains a target audio signal according to a music source, and controls the target amplifier to play the target audio signal.

[0048] In some embodiments of the present invention, determining whether the ambient light meets the start-up condition of the music rhythm mode includes:

[0049] If the atmosphere light is not in a working state, determining that the atmosphere light meets the start-up condition of the music rhythm mode;

[0050] If the atmosphere light is in working state, the priority of the current working mode of the atmosphere light is compared with the priority of the music rhythm mode;

[0051] The priority of the working mode of the atmosphere light and the priority of the music rhythm mode are preset by the user;

[0052] If the priority of the music rhythm mode of the atmosphere light is higher than the priority of the current working mode, it is determined that the atmosphere light meets the start-up condition of the music rhythm mode.

[0053] In some embodiments of the present invention, the user pre-sets the priority of each working mode of the atmosphere light. Exemplarily, the working modes of the atmosphere light include: door opening warning mode. That is, after the vehicle is powered on and the door is not closed, the atmosphere light will light up to remind the owner that the door is not closed. At this time, the atmosphere light is in door opening warning mode. If the user sets the priority of the door opening warning mode to be higher than the priority of the music rhythm mode, then when the atmosphere light is in the door opening warning mode, the atmosphere light does not meet the start-up conditions of the music rhythm mode and will continue to be in the door opening warning mode until the door is closed.

[0054] Step 120: If the ambient light meets the start-up conditions of the music rhythm mode, and the music rhythm mode of the ambient light is the color following mode,

[0055] The main color of the cover image of the music player interface displayed on the target display is extracted in real time, and the corresponding color to be emitted is determined among all the luminous colors of the atmosphere light according to the main color, and a first color signal is generated according to the color to be emitted.

[0056] In some embodiments of the present invention, extracting the main color of the cover image of the music player interface in the target display in real time includes:

[0057] Identifying the color of each pixel in the cover image;

[0058] According to a preset color classification rule, each of the pixels is classified, pixels of the same color are classified into the same color group, a plurality of color groups are obtained, and the color group with the largest number of pixels is determined as the main color group;

[0059] The number of pixels with the same color in the main color group is counted, and the color with the largest number of pixels in the main color group is used as the main color of the cover image.

[0060] Preferably, the smart cockpit controller obtains the cover image of the music player interface displayed in the target display, imports the cover image into the image editing program, comprehensively scans and analyzes the cover image, and identifies the color of each pixel in the cover image. The smart cockpit controller uses the color clustering method to calculate the similarity of colors, and groups pixels whose color similarity is greater than a preset threshold together to form different color groups. The number of pixels in each color group is counted to distinguish between the main color and the auxiliary color in the image. For example, each color group corresponds to a color tone, and the color tone corresponding to the color group with the largest number of pixels is the main color tone, followed by the auxiliary color tone. The image editing program further counts the number of pixels with the same color in the main color group, and extracts the color with the largest number of pixels in the main color group as the color that has the greatest impact on the overall visual effect, that is, the main color of the cover image.

[0061] In some embodiments of the present invention, extracting the main color of the cover image of the music player interface displayed on the target display in real time also includes:

[0062] If the operation of extracting the main color of the cover image of the music player interface displayed on the target display fails, reading the main color of the historical cover image with the most recent recording time in the target storage space to generate a corresponding second color signal;

[0063] After each operation of extracting the main color of the cover image of the music player interface displayed on the target display, the extracted main color of the cover image is recorded in the target storage space as the main color of the historical cover image.

[0064] Preferably, the color coordinates of the main colors of the extracted cover image are recorded in the target storage space.

[0065] In some embodiments of the present invention, determining a corresponding color to be emitted from among all the emitting colors of the atmosphere lamp according to the main color includes:

[0066] Calculating the difference between the color coordinates of each luminous color of the ambient light and the color coordinates of the primary color respectively;

[0067] The luminescent color whose color coordinates have the smallest difference with the color coordinates of the primary color is selected as the corresponding color to be emitted.

[0068] In some embodiments of the present invention, the intelligent cockpit controller obtains the color coordinates of the luminous color of the ambient light according to the luminous parameters of the ambient light, and the ambient light has at least two luminous colors. The intelligent cockpit controller calculates the difference between the color coordinates of each luminous color and the color coordinates of the primary color, and selects the luminous color with the smallest difference as the color to be emitted.

[0069] Step 130: Send the first color signal to a second controller, so that the second controller controls the color of the atmosphere light according to the color signal of the atmosphere light.

[0070] Specifically, the intelligent cockpit controller converts the color to be emitted into a first color signal, and sends the first color signal to the second controller via a CAN FD (CAN with Flexible Data Rate, referred to as CAN FD) bus. Preferably, the second controller is an ambient light controller, which can be used to control the switch function, color and brightness of the ambient light.

[0071] The control method of the vehicle-mounted atmosphere light provided by the present invention has the ability to recognize the cover color of the music player interface displayed on the vehicle computer in real time. When the vehicle plays music, the first controller sends the cover color of the music player interface to the second controller, and the second controller calculates and controls the atmosphere light to display an atmosphere light effect matching the current cover color according to the change of the cover color, thereby improving the flexibility of the atmosphere light control.

[0072] Embodiment 2, Figure 2 FIG. 2 is a flow chart showing another embodiment of a method for controlling a vehicle-mounted ambient light provided by the present invention, wherein the method is executed by a first controller. Figure 2 As shown, the method comprises the following steps:

[0073] Step 210: Receive a music play request from the user and determine whether the ambient light meets the start-up conditions of the music rhythm mode.

[0074] Step 220: If the ambient light meets the activation condition of the music rhythm mode, and the music rhythm mode of the ambient light is not the color following mode,

[0075] Then, the corresponding color information is calculated according to the color data of the ambient light set by the user or the default color data; and the color information is converted into a third color signal.

[0076] Step 230: Send the third color signal to the second controller, so that the second controller controls the color of the ambient light according to the third color signal.

[0077] In some embodiments of the present invention, the user can set the color of the ambient light in the music rhythm mode and the default color of the ambient light in the music rhythm mode at any time. The color data of the ambient light set by the user in real time is monochrome data or multi-color data, and the default color data set by the user is monochrome data or multi-color data.

[0078] Among them, the user can specify one of the luminous colors of the atmosphere light as the color data; the user can set a random luminous color as the color data; the user can specify multiple luminous colors to cycle as the color data; the user can set multiple random luminous colors, or randomly cycle multiple luminous colors as the color data.

[0079] The first controller calculates the corresponding color information according to the color data of the atmosphere light set by the user or the default color data; if the user sets the color data of the atmosphere light, the color information is calculated using the color data of the atmosphere light set by the user. If the user does not set the color data of the atmosphere light, the color information is calculated using the default color data; the default color data is pre-stored in the first controller. The first controller converts the color information into a third color signal so that the second controller controls the color of the atmosphere light according to the third color signal.

[0080] This process is the same as the control method of the vehicle ambient light in the above embodiment, and will not be described in detail here.

[0081] Embodiment 3, Figure 3 FIG. 1 is a flow chart showing another embodiment of a method for controlling a vehicle-mounted ambient light provided by the present invention, wherein the method is executed by a second controller. Preferably, the second controller is an ambient light controller. Figure 3 As shown, the method comprises the following steps:

[0082] Step 310: when receiving the target color signal sent by the first controller, receiving the audio analog signal from the target power amplifier in real time, performing frequency domain analysis on the audio analog signal played by the target power amplifier, and obtaining amplitude data of frequency domain signals of several frequency bands;

[0083] Wherein, the target color signal is generated by the first controller using the above-mentioned vehicle ambient light control method.

[0084] In some embodiments of the present invention, the target color signal is the first color signal, the second color signal or the third color signal mentioned above.

[0085] In some embodiments of the present invention, an audio analog signal is received from a target power amplifier in real time, and a frequency domain analysis is performed on the audio analog signal played by the target power amplifier to obtain amplitude data of frequency domain signals of several preset frequency bands, including:

[0086] Receive audio analog signals of several preset frequency bands from a target power amplifier in real time;

[0087] The audio analog signals of the preset frequency bands are obtained by processing the target audio signal by the target power amplifier; the target audio signal is sent by the first controller;

[0088] The audio analog signals of several preset frequency bands are respectively subjected to frequency domain analysis to obtain frequency domain signals of several preset frequency bands and amplitude data of the frequency domain signals of several corresponding frequency bands.

[0089] Preferably, the smart cockpit controller transmits the target audio signal to the target amplifier via the Automotive Audio Bus (A2B). The target amplifier collects and quantizes the target audio signal transmitted by the smart cockpit controller, wherein the target audio signal is a digital signal. The target amplifier converts the target audio signals of different frequencies into analog signals of different frequency bands through a digital-to-analog converter (DAC), and sends them to the corresponding speaker channels respectively, tunes the analog signals in different channels according to the sense of hearing, and solidifies the amplification factors of the analog signals in different channels to play the analog signals. The atmosphere light controller receives analog signals from different channels of the target amplifier, and provides a fast Fourier transform algorithm (FFT) to convert the time domain signal into a frequency domain signal to obtain the corresponding signals of different frequency bands and their amplitude data.

[0090] Step 320: taking the maximum amplitude of the frequency domain signal of each of the preset frequency bands, and taking the maximum value among the maximum amplitudes of the frequency domain signal of each of the preset frequency bands as reference data; and controlling the brightness of the atmosphere light according to the reference data;

[0091] The color of the atmosphere light is controlled according to the target color signal.

[0092] In some embodiments of the present invention, controlling the brightness of the atmosphere light according to the reference data includes:

[0093] Determining a brightness value corresponding to the atmosphere light according to the reference data;

[0094] There is a preset corresponding relationship between the reference data and the brightness value of the atmosphere light;

[0095] The brightness of the atmosphere light is controlled according to the brightness value corresponding to the atmosphere light.

[0096] Preferably, the atmosphere light controller collects the maximum amplitude of the signal in each frequency band once at a preset time interval, and takes the maximum amplitude as the rhythmic energy point; according to the corresponding relationship between the rhythmic energy point and the brightness of the atmosphere light, the corresponding brightness value of the atmosphere light is obtained.

[0097] Exemplarily, the target power amplifier converts the target audio signals of different frequencies into analog signals of high frequency band (5KHz-15KHz), middle frequency band (2KHz-4KHz) and low frequency band (20Hz-400Hz), and sends them to the treble channel, middle frequency channel and bass channel of the speaker to play the analog signals. The atmosphere light controller converts the time domain signal into the frequency domain signal, collects the maximum amplitude of the high frequency band (5KHz-15KHz), middle frequency band (2KHz-4KHz) and low frequency band (20Hz-400Hz) every 10ms, and takes the maximum amplitude as the rhythm energy point (range 0-255).

[0098] The correspondence between the rhythmic energy points and the brightness values ​​of the atmosphere lights is: energy points 0-29 correspond to a brightness value of 1, energy points 30-54 correspond to a brightness value of 2, energy points 55-79 correspond to a brightness value of 3, energy points 80-104 correspond to a brightness value of 4, energy points 105-129 correspond to a brightness value of 5, energy points 130-154 correspond to a brightness value of 6, energy points 155-179 correspond to a brightness value of 7, energy points 180-204 correspond to a brightness value of 8, energy points 205-229 correspond to a brightness value of 9, and energy points 230-255 correspond to a brightness value of 10.

[0099] Based on the ambient light brightness value calculated every 10ms, the ambient light controller sends the target color signal and brightness control signal (range 1-10) to the ambient light through the Lin (Local Interconnect Network) bus to control the ambient light for real-time display.

[0100] See also Figure 4 , the interaction between the intelligent cockpit controller, the atmosphere light controller, the central control screen, the power amplifier and the atmosphere light involved in executing the vehicle atmosphere light control method in some embodiments of the present invention is specifically described, including the following steps:

[0102] Step 402: The smart cockpit controller receives a music play request from the user and determines whether the ambient light meets the start-up conditions of the music rhythm mode.

[0103] Step 403: If the ambient light meets the start-up conditions of the music rhythm mode, and the music rhythm mode of the ambient light is the color following mode, the smart cockpit controller extracts the main color of the cover image of the music player interface displayed on the target display in real time.

[0104] Step 404: If the cover image of the music player interface is successfully acquired, the smart cockpit controller determines a corresponding color to be emitted from among all the luminous colors of the ambient light according to the main color, and generates a first color signal according to the color to be emitted;

[0105] If the cover image of the music player interface is not successfully obtained, the smart cockpit controller reads the main color of the historical cover image with the most recent recording time and generates a corresponding second color signal.

[0106] Step 405: The smart cockpit controller sends the first color signal / the second color signal to the ambient light controller.

[0107] Step 406: The power amplifier sends the audio analog signal to the ambient light controller.

[0108] Step 407: The ambient light controller receives the audio analog signal from the power amplifier, performs frequency domain analysis on the audio analog signal played by the target power amplifier, and obtains amplitude data of frequency domain signals of several frequency bands.

[0109] Step 408: The ambient light controller takes the maximum amplitude of the frequency domain signal of each preset frequency band, and takes the maximum value among the maximum amplitudes of the frequency domain signal of each preset frequency band as reference data; and determines the brightness value corresponding to the ambient light according to the reference data.

[0110] Step 409: The ambient light controller sends a target color signal and a brightness control signal to the ambient light according to the first color signal / second color signal sent by the smart cockpit controller and the brightness value corresponding to the ambient light, so that the ambient light executes the corresponding color and brightness.

[0111] See also Figure 5 , the interaction between the intelligent cockpit controller, the atmosphere light controller, the central control screen, the power amplifier and the speaker involved in executing the vehicle atmosphere light control method in some embodiments of the present invention is specifically described, including the following steps:

[0112] Step 501: The user issues a music playback command on the central control screen, and the vehicle central control sends the user's music playback request to the smart cockpit controller.

[0113] Step 502: The smart cockpit controller receives a music playing request from the user and sends a playing instruction of a target audio signal to the power amplifier.

[0114] Step 503: The power amplifier receives a play instruction of a target audio signal sent by the smart cockpit controller, and processes the target audio signal to obtain an audio analog signal.

[0115] Step 504: The power amplifier sends the audio analog signal to the speaker.

[0116] Step 505: The power amplifier sends the audio analog signal to the ambient light controller.

[0117] Step 506: The speaker plays the audio analog signal.

[0118] The control method of the vehicle-mounted ambient light provided by the present invention has the ability to identify the cover color of the music player interface displayed on the vehicle computer and the music rhythm. When the vehicle plays music, the first controller sends the cover color of the music player interface to the second controller, and the second controller combines the cover color and the change of the audio signal rhythm to calculate and control the ambient light to display the ambient light effect matching the current music rhythm type and cover color, thereby improving the flexibility of the ambient light control.
