[0025] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0026] To meet the increasingly diverse needs of users, some vehicles are currently equipped with light curtains on their exterior surfaces. The so-called light curtain refers to a display device installed on the outside of the vehicle, usually composed of multiple LED (Light Erittikg Diode) lamp beads, which can achieve a screen-like lighting effect and display various patterns, texts or animation effects by controlling its brightness and color. The light curtain not only has a certain lighting effect, but also can display vehicle information, realize interaction with the outside world, and enhance the vehicle's appearance design.

[0027] The refresh rate of the light curtain is a fixed value. Accordingly, the light curtain of the vehicle in the related art can only display information with a frame rate that is compatible with the refresh rate of the light curtain, otherwise it will cause the display effect to be stuck, flicker or incoherent. At present, the light curtain in the related art is only used to display information with a specific frame rate, and the above-mentioned problems such as stuck, flicker or incoherent display effects are avoided by limiting the input source frame rate. Therefore, the related art still cannot adapt to the situation of variable input sources, the input adaptability of the light curtain is poor, and the application flexibility is insufficient.

[0028] The present application provides a vehicle, which includes a light curtain arranged on the outer surface of the vehicle and an acoustic-optical translator electrically connected to the light curtain. The acoustic-optical translator is used to convert the sound information in the vehicle into information to be displayed on the light curtain, that is, the information to be displayed on the light curtain changes in real time as the sound information in the vehicle changes. Therefore, in the scenario where the present application obtains the information to be displayed through the acoustic-optical translator, the information to be displayed on the light curtain is flexible and changeable. The method in the related art of avoiding the problems of stuck, flickering or incoherent display effects caused by frame rate mismatch by limiting the input source frame rate is no longer applicable. It is urgent to solve the problems of poor input adaptability and insufficient application flexibility of the light curtain to ensure the linkage application of the acoustic-optical translator and the light curtain in the vehicle.

[0029] To solve this problem, combined with Figure 1 As shown, corresponding to the above-mentioned vehicle, an embodiment of the present application provides a method for controlling a vehicle light curtain, and the control method includes steps S10 to S30.

[0030] Step S10, obtaining information to be displayed on the light curtain through the sound and light translator, where the information to be displayed includes information converted from information input by the user through the sound and light translator.

[0031] Step S20, when the first frame rate of the information to be displayed does not match the second frame rate of the light curtain, adjusting the frame rate of the information to be displayed to generate display information with the second frame rate.

[0032] Here, the second frame rate of the light curtain is a frame rate corresponding to the refresh frequency of the light curtain, that is, the number of image frames that the light curtain can display per unit time at the refresh frequency of the light curtain.

[0033] Step S30, controlling the light curtain to display the display information.

[0034] Since the light curtain is composed of multiple LED lamp beads, controlling the light curtain to display the display information here specifically involves converting the display information into the corresponding LED matrix in real time, and transmitting it to the light curtain processor in the light curtain in real time. The light curtain processor lights up the corresponding lamp beads in the light curtain according to the LED matrix to display the display information.

[0035] The vehicle light curtain control method provided in the embodiment of the present application is adopted, and the information converted from the information input by the user through the sound and light translator is used as the information to be displayed on the light curtain. Since the information to be displayed is flexible and changeable, there is a high risk that the first frame rate of the information to be displayed and the second frame rate of the light curtain will not match. When the first frame rate of the information to be displayed does not match the second frame rate of the light curtain, the frame rate of the information is adjusted to generate display information consistent with the refresh frequency of the light curtain, so as to avoid display problems caused by frame rate mismatch, and ensure that the light curtain can display content stably and smoothly. In this way, a good light curtain display effect can be achieved without strictly limiting the information to be displayed, so that the light curtain can receive a variety of user-defined content, which is conducive to improving the input adaptability of the light curtain in the vehicle, thereby improving the flexibility of the application of the light curtain. The sound and light transducer and the light curtain can be used in conjunction in the vehicle, which is conducive to optimizing the user experience.

[0036] The present application provides a control system for a vehicle light curtain, the control system for the vehicle light curtain includes one or more processors, and is used to implement a control method for the vehicle light curtain. In at least some embodiments, the aforementioned vehicle includes the control system, and the control system is electrically connected to the vehicle light curtain.

[0037] In some embodiments, the control system of the vehicle light curtain includes a processor inside the sound and light translator, and the acquisition of the information to be displayed on the light curtain is realized through the processor inside the sound and light translator; in some embodiments, the control system of the vehicle light curtain includes a processor independent of the sound and light translator, and the sound and light translator only serves as an input end to perform part of the process of acquiring the information to be displayed, and the specific scheme for the processor independent of the sound and light translator to obtain the information to be displayed on the light curtain is realized.

[0038] In some embodiments, the vehicle further includes a central control screen disposed inside the vehicle. The central control screen is electrically connected to the control system, and the control method further includes: controlling the central control screen to synchronously display the display information with the light curtain. In this way, the user inside the vehicle can learn the display content of the external light curtain in real time through the central control screen, which is convenient for the user to confirm the content. Further, in some embodiments, the central control screen is used to adjust the display information of the light curtain. That is, the user can manually adjust the display information through the central control screen. In this way, it is convenient for the user to timely adjust and correct the display information of the light curtain.

[0039] Combined with Figure 2 As shown, in some embodiments, the first frame rate is less than the second frame rate. At this time, in step S20 described above, when the first frame rate of the information to be displayed does not match the second frame rate of the light curtain, the frame rate of the information to be displayed is adjusted to generate display information with a frame rate of the second frame rate, including steps S211 to S212.

[0040] Step S211, when the first frame rate is less than the second frame rate, calculate the difference between the second frame rate and the first frame rate, and determine the total number of supplementary frames to be inserted per unit time according to the difference.

[0041] The supplementary frame is a repeated frame used to make up the number of frames.

[0042] Step S212, insert supplementary frames into at least part of the frame intervals of the information to be displayed according to the total number of supplementary frames until the second frame rate is reached, as the display information.

[0043] In this way, the frame rate adjustment of the information to be displayed can be realized, so that it is consistent with the second frame rate of the light curtain, thereby ensuring a good display effect of the light curtain.

[0044] Specifically, in some embodiments, supplementary frames are inserted at least partially into the frame intervals of the information to be displayed according to the total number of supplementary frames until the second frame rate is reached, including: calculating the average value of the total number of supplementary frames relative to the number of frame intervals to determine the minimum number k of supplementary frames to be inserted in each frame interval. According to the total number of supplementary frames and the minimum number k of supplementary frames to be inserted in each frame interval, calculate the number r of remaining supplementary frames. Insert (k + 1) supplementary frames into the first r frame intervals and insert k supplementary frames into the remaining frame intervals. In this way, a more uniform distribution of supplementary frames can be achieved, which is beneficial to achieving a more uniform frame interpolation effect, thereby facilitating the optimization of the final display effect. In addition, it should be noted here that the remaining supplementary frames are directly inserted into the first k frame intervals without further calculating and determining which frame intervals to insert into, which helps to simplify the logic calculation process and avoid adding unnecessary computational burdens while hardly affecting the final display effect.

[0045] Here, the minimum number k of supplementary frames to be inserted in each frame interval is an integer. If the average value of the total number of supplementary frames relative to the number of frame intervals is not an integer, it is rounded down to be the minimum number k. According to the total number of supplementary frames and the minimum number k of supplementary frames to be inserted in each frame interval, calculate the number r of remaining supplementary frames. Specifically, calculate the product between the number of frame intervals and the minimum number k, and subtract this product from the total number of supplementary frames. The resulting difference is the number r of remaining supplementary frames.

[0046] That is, if the first frame rate of the information to be displayed is n frames per second and the second frame rate of the light screen is m frames per second, then calculate the difference between the second frame rate and the first frame rate, and determine that the total number of supplementary frames to be inserted in each unit time is (m - n) frames according to the difference. At this time, the number of frame intervals of the information to be displayed is (n - 1). At this time, the average value of the total number of supplementary frames relative to the number of frame intervals is [(m - n) / (n - 1)]. If this value is an integer, then the minimum number k of supplementary frames to be inserted in each frame interval is (m - n) / (n - 1); if this value is not an integer, then the minimum number k of supplementary frames to be inserted in each frame interval is the value obtained by rounding down [(m - n) / (n - 1)]. The number r of remaining supplementary frames is r = (m - n) - (n - 1) * k.

[0047] Exemplarily, if the first frame rate of the information to be displayed is 10 frames per second and the second frame rate of the light screen is 105 frames per second, then calculate the difference between the second frame rate and the first frame rate, and determine that the total number of supplementary frames to be inserted per unit time is 95 frames according to the difference. The number of frame intervals of the information to be displayed is 9. At this time, the average number of the total number of supplementary frames relative to the number of frame intervals is not an integer. Rounding down, the minimum number of supplementary frames to be inserted in each frame interval is 10, and the number of remaining supplementary frames is 5. Therefore, 11 supplementary frames are inserted in the first 5 frame intervals of the information to be displayed, and 10 supplementary frames are inserted in the last 5 frame intervals. In this way, the frame rate conversion of the information to be displayed is completed.

[0048] In some embodiments, the judgment process between the number of frame intervals and the total number of supplementary frames can be increased. When the total number of supplementary frames is greater than the number of frame intervals, calculate according to the above method; when the total number of supplementary frames is less than or equal to the number of frame intervals, insert a supplementary frame sequentially in each frame interval until the second frame rate is reached. In this way, it is beneficial to simplify the calculation process.

[0049] Combined with Figure 3 As shown, in some embodiments, the first frame rate is greater than the second frame rate. At this time, the aforementioned step S20, when the first frame rate of the information to be displayed does not match the second frame rate of the light screen, performs frame rate adjustment on the information to be displayed to generate display information with the second frame rate, including steps S221 to S222.

[0050] Step S221, when the first frame rate is greater than the second frame rate, calculate the difference between the first frame rate and the second frame rate, and determine the total number of frames to be deleted per unit time according to the difference.

[0051] Step S222, according to the total number of frames to be deleted, delete frames intermittently from the information to be displayed until the second frame rate is reached, as the display information.

[0052] In this way, the frame rate adjustment of the information to be displayed can be realized, so that it is consistent with the second frame rate of the light screen, thereby ensuring a good display effect of the light screen. Intermittently deleting frames from the information to be displayed is beneficial to ensuring the uniformity of frame extraction, thereby further optimizing the display effect of the light screen.

[0053] Specifically, in some embodiments, according to the total number of frames to be deleted, deleting frames intermittently from the information to be displayed until the second frame rate is reached, as the display information, includes: determining the deletion interval according to the total number of frames to be deleted and the first frame rate; deleting the frames of the information to be displayed according to the deletion interval to obtain display information with the second frame rate. In this way, it is beneficial to ensuring the uniformity of frame extraction, thereby further optimizing the display effect of the light screen.

[0054] Here, determining the deletion interval according to the total number of frames to be deleted and the first frame rate includes calculating the quotient obtained by dividing the number of frames corresponding to the first frame rate by the total number of frames to be deleted, and determining the deletion interval according to the quotient. If the quotient is an integer, the quotient is directly used as the deletion interval; if the quotient is not an integer, the quotient is rounded down as the deletion interval. Deleting the frames of the information to be displayed according to the deletion interval means deleting the frames in the information to be displayed every the deletion interval.

[0055] That is, if the first frame rate of the information to be displayed is n frames per second, and the second frame rate of the light curtain is m frames per second, then the difference between the second frame rate and the first frame rate is calculated, and the total number of supplementary frames to be inserted per unit time is determined to be (nm) frames based on the difference. Calculate the quotient [n / (nm)] obtained by dividing the number of frames corresponding to the first frame rate by the total number of frames to be deleted. If the quotient is an integer, the deletion interval l is determined to be n / (nm); if the quotient is not an integer, the deletion interval l is determined to be the value obtained by rounding down [n / (nm)]. The positions of the frames to be deleted are determined to be the lth frame, the 21th frame, and up to the (nm)*kth frame.

[0056] If the first frame rate of the information to be displayed is 30 frames per second and the second frame rate of the light curtain is 25 frames per second, the difference between the second frame rate and the first frame rate is calculated, and the total number of supplementary frames to be inserted per unit time is determined to be 5 frames based on the difference. The quotient obtained by dividing the number of frames corresponding to the first frame rate by the total number of frames to be deleted is 6, which is used as the deletion interval, and the positions of the frames to be deleted are determined to be the 6th frame, the 12th frame, the 18th frame, the 24th frame and the 30th frame. In this way, the frame rate conversion of the information to be displayed is completed.

[0057] In some implementations, when the first frame rate is greater than the second frame rate, the control method further includes a process of determining the total number of frames to be deleted. If the total number of frames to be deleted is less than or equal to half of the number of frames corresponding to the first frame rate, the position of the frame to be deleted can be determined according to the above scheme. If the total number of frames to be deleted is greater than half of the number of frames corresponding to the first frame rate, half of the frames in the information to be displayed are first deleted with a deletion interval of 1, and then the position of the frame to be deleted is determined according to the above scheme.

[0058] Next, a specific description is given of the process of obtaining the information to be displayed on the light curtain through the sound and light translator.

[0059] Combination Figure 4 As shown, in some embodiments, step S10, obtaining information to be displayed on the light curtain through an audio-visual translator, includes steps S111 to S112.

[0060] Step S111 : When receiving a start instruction for indicating starting to generate information to be displayed, voice information of a user in the vehicle is collected.

[0061] The start instruction here can be obtained by inputting through the central control screen set in the vehicle. When the user clicks or long-presses the setting function button displayed on the central control screen, the voice information of the user inside the vehicle is collected. Or, a hardware switch is separately set inside the vehicle, for example, set near the seat or the seat armrest. When the user clicks or long-presses the hardware switch, it is considered that the start instruction for indicating the start of generating the information to be displayed is received, and the voice information of the user inside the vehicle is collected. Or, the start instruction is determined through a voice command. The voice information inside the vehicle is monitored by default. If the set keyword is not monitored, the monitored voice information is not stored and processed subsequently; if the set keyword is monitored, the voice information of the user inside the vehicle is formally collected, stored, and calculated. Or, the start instruction is determined through scenario triggering. Scenarios for triggering the start instruction are preset in advance, such as the driving mode of the vehicle, the environment outside the vehicle, etc. When the current scenario meets the preset scenario for triggering the start instruction, it is considered that the start instruction for the user to indicate the start of generating the information to be displayed is received, and the voice information of the user inside the vehicle is collected. These multiple methods can be used alone or in combination during implementation, and no specific limitation is made here.

[0062] A voice collection device, such as a microphone, is also set inside the vehicle. The voice collection device is used to collect the sound information inside the vehicle, and the microphone or the control system of the vehicle light screen analyzes and determines the voice information of the user inside the vehicle according to the original sound information inside the vehicle.

[0063] Step S112: Generate the information to be displayed on the light screen according to the voice information. The information to be displayed includes text and / or pictures.

[0064] In this way, the user can update the content of the light screen at any time through the start instruction and the voice information, greatly enhancing the interactivity between the vehicle and the user. At the same time, the application flexibility of the light screen is extended and improved, making it better meet the personalized needs of users.

[0065] In some embodiments, generating the information to be displayed on the light screen according to the voice information includes: performing text recognition on the voice information; using the recognized text as the information to be displayed. The text is displayed in the default format. In this way, complex algorithms are not required when accurately expressing the content output by the user, which is beneficial to simplifying the calculation.

[0066] In some embodiments, generating information to be displayed on the light screen according to voice information includes: performing character recognition on the voice information; determining at least part of the character color, character size, and character font according to the first voice feature of the voice information; and determining the information to be displayed by combining the recognized characters and at least part of the determined character color, character size, and character font. The first voice feature includes at least part of pitch, intensity, and duration. In this way, the adjustment of the basic characters can be realized according to different first voice features, so as to more accurately express the user's intention. During the implementation process, the corresponding relationship between the first voice feature and at least part of the character color, character size, and character font can be preset in advance, and at least part of the currently corresponding character color, character size, and character font is determined according to the currently monitored first voice feature and the corresponding relationship. In some embodiments, the corresponding relationship between the first voice feature and the emotion is set, the corresponding emotion is determined according to the currently monitored first voice feature, and different character colors, character sizes, or character fonts are corresponding to the emotion.

[0067] Among them, in some embodiments, performing character recognition on the voice information includes: recognizing the corresponding language according to the voice information of the passengers in the vehicle sound and converting it into basic characters; and matching punctuation marks on the basis of the basic characters according to at least part of the speech rate, pause time, and context content in the voice information. In this way, it is beneficial to improve the readability of the information to be displayed, so as to ensure that the information to be displayed more accurately transmits the user's intention. In at least some embodiments, character recognition is performed on the voice information to obtain characters and emoji. In this way, it is beneficial to further ensure that the information to be displayed more accurately conveys the user's intention.

[0068] In some embodiments, generating information to be displayed on the light screen according to voice information includes: generating a picture according to the second voice feature of the voice information as the information to be displayed. The second voice feature includes at least part of frequency, pitch, and speech rate. In this way, the light screen display can provide richer and more personalized visual content, which is beneficial to further enhance the intuitiveness of user interaction, so as to accurately convey the user's intention. For example, by analyzing the frequency, pitch, and speech rate of the sound to judge at least one of the passenger's gender and age, and generating the corresponding avatar picture as the information to be displayed. In other embodiments, it may also be other pictures corresponding to the second voice feature. For example, a fast and high-pitched voice may generate a more dynamic and energetic picture, while a low and slow voice may generate a more steady and quiet picture.

[0069] It can be understood that the above characters and pictures can be used as the information to be displayed independently, or can be used as the information to be displayed after combination.

[0070] Combine Figure 5As shown, in some embodiments, in step S10, the information to be displayed on the light screen is obtained through an acousto-optic translator, including steps S121 to S122.

[0071] In step S121, the environmental information of the vehicle's location is obtained, where the environmental information includes at least some of the location, the landform at the location, the altitude, and the weather.

[0072] Here, in some embodiments, obtaining the environmental information of the vehicle's location includes: obtaining the environmental information of the vehicle's location when an enabling instruction for indicating the start of generating the information to be displayed is received.

[0073] In step S122, a background picture is generated based on the environmental information as the information to be displayed on the light screen. Among them, the background picture is used to be displayed alone on the light screen or to be displayed on the light screen in combination with other information to be displayed.

[0074] In this way, generating a background picture according to the real-time information of the vehicle's location can make the content displayed on the light screen match the surrounding environment, which is beneficial to improving the display effect of the light screen. At the same time, since the background picture can be dynamically adjusted according to environmental changes, for example, showing a rain scene background on rainy days and a mountain scene background in mountainous areas, it can bring a more immersive interaction experience to users and optimize the user's experience.

[0075] Exemplarily, in some embodiments, the vehicle is provided with a positioning device, such as a GPS positioning module disposed inside the acousto-optic translator. The longitude and latitude of the vehicle, that is, the location of the vehicle, can be obtained in real time according to this positioning device. According to this location, the corresponding weather information and landform information can be obtained. By integrating the weather information and the landform details, a background picture is intelligently generated as the information to be displayed on the light screen.
