[0026] Description of reference numerals: 100 - judgment module; 200 - analysis module; 300 - control module DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present application. Examples of the embodiments 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 application, and should not be construed as limiting the present application.

[0028] The following describes the detection method, device, vehicle and storage medium of the labeled data sample of the embodiment of the present application with reference to the accompanying drawings. Specifically, Figure 1 A flowchart of a method for collaboratively controlling vehicle ambient lights and welcome sounds provided in an embodiment of the present application.

[0029] like Figure 1 As shown, the method for collaboratively controlling the vehicle ambient light and the welcome sound includes the following steps:

[0030] In step S101 , it is determined whether the vehicle meets the welcome triggering condition.

[0031] Specifically, if Figure 2 As shown, to ensure that PCM audio can be played quickly and reliably when the user gets on the vehicle, first, it will be determined whether the vehicle meets the welcome trigger condition. The welcome trigger condition is whether the vehicle is successfully unlocked and the entire vehicle is powered on. If the vehicle is successfully unlocked and the entire vehicle is powered on, it is determined that the vehicle meets the welcome trigger condition. At this time, the domain controller can control the target welcome PCM audio file to play.

[0032] In step S102, if the vehicle meets the welcome trigger condition, the target welcome PCM audio file pre-stored in the write-protected data partition is read, and the target welcome PCM audio file is controlled to play within the preset time. At the same time, the target welcome PCM audio file is parsed using a preset algorithm to obtain the audio frequency of the target welcome PCM audio file.

[0033] Among them, the preset time and the preset algorithm can be set by those skilled in the art according to actual usage requirements and are not specifically limited here.

[0034] Specifically, if the vehicle meets the welcome trigger conditions, that is, when the vehicle is unlocked or opened and the entire vehicle is powered on, the domain controller will detect the power-on signal, thereby synchronizing with the vehicle status to avoid false triggering. If it is in the domain controller low power mode, the domain controller can complete the screen wake-up within the preset time (for example, 3 seconds), and read the target welcome PCM audio file pre-stored in the write-protected data partition, and then play the target welcome PCM audio file; if the domain controller is restarted and initialized, the domain controller's DSP (Digital Signal Processing) audio module can complete the driver initialization within 3 seconds after the domain controller host is powered on, and play the target welcome PCM audio file after reading the write-protected partition.

[0035] Among them, the smart cockpit domain control host will preset a PCM audio file in the write-protected data partition when leaving the factory, that is, the write-protected data partition, as the default boarding welcome sound. The write-protected data partition can be configured through the driver to open an independent partition in the memory. This partition cannot be overwritten by system upgrades, nor can it be modified or deleted by non-system applications.

[0036] It should be noted that if it cannot be woken up within the preset time (for example, 3 seconds), it means that the current domain control has failed, such as system abnormality. If this happens, it will usually be monitored by the MCU (Microcontroller Unit) or R core to restart the computer. At this time, the welcome sound is played based on the playback process initialized by the restart.

[0037] Furthermore, while controlling the target welcoming PCM audio file to play within 3 seconds, a preset algorithm (such as an audio analysis algorithm FFT (Fast Fourier Transform)) is used to analyze the target welcoming PCM audio file to obtain the audio frequency of the target welcoming PCM audio file.

[0038] Specifically, if Figure 2 As shown in the figure, when the vehicle is powered on, the domain controller reads the factory default target welcome PCM audio file or the user-defined new welcome PCM audio file from the write-protected data partition. At the same time, an audio analysis algorithm, such as FFT or Fftw, needs to perform spectrum analysis on the default target welcome PCM audio file or the new welcome PCM audio file. Figure 3 The figure shows a schematic diagram of the FFT conversion process. FFT can convert each audio signal into frequency components, so that the audio frequency of each audio signal can be obtained separately. This is because the audio signal is collected and separated into frequency components within a period of time. These audio components are each sinusoidal oscillation waves at different frequencies, with their own amplitude and phase, so the audio frequency is obtained through the FFT algorithm.

[0039] In step S103 , the audio frequency is converted into LIN data, and the LIN data is sent to the ambient light control component to control the ambient light control component to dynamically control the vehicle ambient light rhythm according to the LIN data.

[0040] Preferably, converting the audio frequency into LIN data includes: dividing the audio frequency into frequency band numbers to obtain the amplitude spectrum energy within each frequency band number; summing the amplitude spectrum energy within each frequency band number to obtain the target frequency band number corresponding to the highest amplitude spectrum energy, and converting the target frequency band number into LIN data.

[0041] Specifically, the domain control will divide the frequency band numbers, that is, divide the acquired audio frequencies into 64 levels (0-63), which correspond to the 64 color numbers (0-63) of the ambient light respectively, and convert them into LIN data according to the ambient light LIN matrix rules, and send them in a 100ms cycle. Among them, the changes in rhythm, melody and other elements in the audio frequency of the welcoming sound are converted into LIN data, which can drive the ambient light to change color and brightness according to the rhythm or emotion of the audio, so that the visual effect matches the auditory experience, enhancing the user's immersion and welcoming experience. The LIN data can be based on the sum of the amplitude spectrum energy in each frequency band number to obtain the target frequency band number corresponding to the highest amplitude spectrum energy as the ambient light color control signal, thereby converting the target frequency band number into LIN data.

[0042] Among them, the atmosphere light LIN matrix can include atmosphere light on, brightness adjustment, color selection, and status feedback. The welcoming rhythm mainly corresponds to the CDC_ALMColour_adjust color selection signal in the matrix. Among them, the atmosphere light color table is shown in Table 1, and the atmosphere light LIN matrix is ​​shown in Table 2:

[0043] Table 1

[0044]

[0045]

[0046]

[0047] Table 2

[0048]

[0049]

[0050] Then, the converted LIN data is sent to the ambient light control component. At this time, the ambient light control component can obtain the color and brightness of the ambient light, and dynamically control the vehicle ambient light to perform corresponding rhythm according to the audio frequency based on the LIN data.

[0051] It should be noted that the embodiment of the present application can also use CAN (Controller Area Network) data, which is mainly determined based on the communication settings of the vehicle atmosphere lights.

[0052] Preferably, the ambient light control component is controlled to dynamically control the vehicle ambient light rhythm according to the LIN data, including: determining whether the target frequency band number in the LIN data is within the target frequency band number range; if the target frequency band number is within the target frequency band number range, then the ambient light control component is controlled to dynamically control the vehicle ambient light rhythm according to the LIN data, otherwise, the vehicle ambient light rhythm continues to be dynamically controlled based on the previous LIN data.

[0053] Specifically, in order to avoid the accuracy of the change in the color of the ambient light, after receiving the LIN data, it is necessary to further judge the target frequency band number in the LIN data to see whether the target frequency band number is within the target frequency band number range, that is, whether the target frequency band number is within the 0-63 frequency band. If the target frequency band number is within the target frequency band number range, it means that the ambient light data sent by the domain control is correct at this time, so the ambient light control component can dynamically control the vehicle ambient light rhythm according to the new LIN data received; if the target frequency band number exceeds the target frequency band number range, that is, the target frequency band number exceeds the 0-63 frequency band range, it means that the data sent by the domain control is wrong, and the ambient light control component needs to discard the erroneous data, and then continue to dynamically control the vehicle ambient light rhythm based on the previous LIN data, that is, maintain the rhythm of the previous valid ambient light color.

[0054] Furthermore, the domain controller will also memorize the color of the ambient light when the vehicle was last powered off. For example, if it memorizes blue, the MCU will send the default ambient light memory color the next time the vehicle is powered on. After the welcoming rhythm (such as the color during the rhythm is red, yellow, purple, and light green), the ambient light returns to the memorized color.

[0055] Preferably, after controlling the ambient light control component to dynamically control the vehicle ambient light rhythm according to the LIN data, it also includes: judging whether the user's target welcome PCM audio file modification instruction is received; if the target welcome PCM audio file modification instruction is received, then receiving the user's new welcome PCM audio file, and replacing the target welcome PCM audio file with the new welcome PCM audio file, and storing it in the write-protected data partition.

[0056] Preferably, before receiving the user's new welcome PCM audio file, it also includes: receiving a text modification instruction or a voice modification instruction of the target welcome PCM audio file; if the modification instruction is a text modification instruction, receiving the user's text welcome information, and converting the text welcome information into a corresponding new welcome PCM audio file; if the modification instruction is a voice modification instruction, recognizing the voice modification instruction, generating the user's voice welcome information, and converting the voice welcome information into a corresponding new welcome PCM audio file.

[0057] Specifically, if Figure 2As shown, the user can personalize and modify the target welcome PCM audio file according to his or her preferences. If the user wants to personalize, he or she needs to send the target welcome PCM audio file modification instruction through text or voice. If the modification instruction is a text modification instruction, the user's text welcome information is received and the text welcome information is converted into the corresponding new welcome PCM audio file. For example, the user enters the welcome sound modification function interface on the smart cockpit domain control display screen, customizes the welcome text, such as "Welcome my queen to make a shining appearance", etc., clicks and then clicks the OK modification button; if the modification instruction is a voice modification instruction, the voice modification instruction is recognized, the user's voice welcome information is generated, and a TTS (Text-to-Speech) engine (such as Google Text-to-Speech API, Microsoft Azure, IBM Watson, etc., or open source libraries such as MaryTTS or eSpeak, etc.) can be used to convert the voice welcome information into the corresponding new welcome PCM audio file. For example, the user sends a message such as "Welcome my Queen to the stage" through voice, and then the voice welcome information is converted into the corresponding new welcome PCM audio file based on the TTS engine, and voice feedback is provided after the modification, and then the new PCM audio file is automatically copied to the write-protected data partition, or the user copies the corresponding new PCM audio file to the write-protected data partition through a USB flash drive to replace the default target welcome PCM audio file for use on the next ride.

[0058] Optionally, users can also search for new PCM audio files on their own, enter the welcome sound modification function interface on the domain control display, select the USB flash drive PCM audio file list, select the PCM audio file and click OK to modify to obtain the new PCM audio file. After receiving the confirmation instruction, the program copies the new PCM audio file to the write-protected data partition to replace the default target welcome PCM audio file.

[0059] It should be noted that before the user modifies the welcome sound, the domain control plays the default welcome sound every time the user gets in the car. After the user modifies it, the modified welcome sound will be played the next time the vehicle is powered on, thereby controlling the rhythm of the vehicle's ambient lights according to the modified welcome sound.

[0060] In summary, the embodiment of the present application can provide a way to implement customized welcome sound + ambient light rhythm without modifying hardware and increasing hardware costs. Through the customized welcome sound combined with the ambient light rhythm, the user can experience the self-defined welcome sound + ambient light rhythm that matches the sound frequency when getting on the car, thereby enhancing the user experience.

[0061] According to the collaborative control method for vehicle ambient lighting and welcome sound proposed in the embodiment of the present application, when the vehicle meets the welcome trigger condition, the target welcome PCM audio file pre-stored in the write-protected data partition is read, and the target welcome PCM audio file is controlled to play within a preset time. At the same time, the target welcome PCM audio file is parsed using a preset algorithm to obtain the audio frequency of the target welcome PCM audio file; the audio frequency is converted into LIN data, and the ambient lighting control component is controlled to dynamically control the vehicle ambient lighting rhythm according to the LIN data. This solves the problem of the welcome sound function and the vehicle ambient lighting working independently and lacking a collaborative effect, resulting in a poor welcome effect and a reduced user experience. By customizing the welcome message and converting the text into a PCM audio file for playback, the intelligent linkage of the welcome audio and ambient lighting is achieved, thereby enhancing the personalized and differentiated experience of the vehicle.

At the same time, the target welcome PCM audio file is analyzed using a preset algorithm to obtain the audio frequency of the target welcome PCM audio file; the control module 300 is used to convert the audio frequency into LIN data, and send the LIN data to the atmosphere light control component to control the atmosphere light control component to dynamically control the vehicle atmosphere light rhythm according to the LIN data.

[0066] Preferably, the control module 300 is specifically used to: divide the audio frequency into frequency band numbers to obtain the amplitude spectrum energy within each frequency band number; sum the amplitude spectrum energy within each frequency band number to obtain the target frequency band number corresponding to the highest amplitude spectrum energy, and convert the target frequency band number into LIN data.

[0068] Preferably, before receiving the user's new welcome PCM audio file, the control module 300 is also used to: receive a text modification instruction or a voice modification instruction of the target welcome PCM audio file; if the modification instruction is a text modification instruction, then receive the user's text welcome information and convert the text welcome information into a corresponding new welcome PCM audio file; if the modification instruction is a voice modification instruction, then recognize the voice modification instruction, generate the user's voice welcome information, and convert the voice welcome information into a corresponding new welcome PCM audio file.
