[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Figure 1 A structural diagram of a vehicle window glass control system provided by an embodiment of the utility model, wherein the vehicle window glass is LED glass, such as Figure 1As shown, the vehicle window glass control system includes: an audio signal receiving module 101, a main control module MCU (Motorcontrol unit) 102 and an LED driving module 103; the audio signal receiving module 101 is communicatively connected to the main control module 102; the main control module 102 is communicatively connected to the LED driving module 103.

[0041] The audio signal receiving module 101 is used to receive an audio signal and transmit it to the main control module 102 .

[0042] The main control module MCU102 is used to convert the audio signal into an LED rhythm control signal, and transmit the LED rhythm control signal to the LED driving module.

[0043] In related technologies, MCU is an embedded system used to control various electronic devices and functions of a vehicle. It is usually a high-performance, low-power microcontroller chip that integrates a processor core, memory, input / output interface, and various peripherals.

[0044] The LED driving module 103 is used to control the LED window glass to display a corresponding rhythmic effect according to the LED rhythmic control signal.

[0045] In one example, the rhythmic effect includes at least one of the brightness, color, color temperature, switching speed, number of lit LED beads, flashing frequency and playback speed of the LED lamp beads.

[0046] The embodiment of the utility model converts the audio signal into an LED rhythm control signal through the main control module, and the LED driving module controls the LED glass to display the rhythm effect along with the rhythm of the music with the LED rhythm control signal, thereby providing users with a more immersive entertainment atmosphere.

[0047] In a possible implementation, the audio signal receiving module includes: an audio acquisition module and a wireless communication module.

[0048] The audio acquisition module is used to collect audio signals output by the vehicle audio device. The wireless communication module is used to receive audio signals output by the mobile device. The audio acquisition module collects audio signals through Ethernet and transmits them to the main control module through Ethernet.

[0049] The audio acquisition module collects the real-time voltage amplitude output by the car speaker, and processes the voltage amplitude output by the vehicle audio device through the forward amplifier and voltage follower to obtain the audio signal. The sampling frequency of this system is designed to be 20khz, and the sampling resolution of the ADC (Analog-to-Digital Converter, analog / digital converter or analog-to-digital converter) of the main control unit (Microcontroller Unit, MCU) is 12 bits, with high sampling accuracy and fast sampling speed. The sampling rate of the ADC must be much smaller than the conversion rate. ADC refers to a device that converts continuously changing analog signals into discrete digital signals. Real-world analog signals, such as temperature, pressure, sound or images, need to be converted into digital forms that are easier to store, process and transmit. The analog / digital converter can achieve this function and can be found in various products. In the application process, the analog-to-digital converter can convert the analog signal into a digital signal representing a certain proportional voltage value.

[0050] The wireless communication module may include a communication module such as Bluetooth, WiFi, etc. The audio signal may be an audio signal of the played music.

[0051] See also Figure 2 , which is a schematic diagram of the vehicle audio collection wiring provided by the embodiment of the utility model. Figure 2 As shown, the vehicle audio output interface is connected to the vehicle speaker and the audio acquisition module of the window glass control system respectively.

[0052] In one possible implementation, the system also includes: an Ethernet communication module, used to transmit vehicle status information to the main control module; the main control module is also used to generate an alarm drive signal when the vehicle status information is abnormal; the LED drive module is also used to control the LED glass to display alarm information according to the alarm drive signal.

[0053] In one example, the vehicle status information of brake failure is transmitted to the main control module through the Ethernet communication module. The main control module generates a corresponding alarm drive signal, and controls the LED glass to display an alarm or distress pattern or text through the LED drive module. Passersby can know that the vehicle is in a distress / alarm state based on the pattern or text on the window, and can provide timely help, increasing the chance of the owner getting timely help.

[0054] In one example, the alarm audio signal output by the vehicle audio output device is transmitted to the audio acquisition module via Ethernet, and then processed by the main control module to generate an alarm driving signal to control the LED glass to display an alarm or distress pattern or text through the LED driving module.

[0055] In one example, the Ethernet communication module can also be linked with the central domain, cockpit domain, body domain, power domain, etc. through a gateway.

[0056] In a possible implementation, a power supply module is connected to the main control module and the LED driving module respectively, and is used to supply power to the main control module and the LED driving module.

[0057] In a possible implementation, the main control module includes a sampling module, a frequency domain conversion module and a digital encoding module; the sampling module is connected to the frequency domain conversion module; the frequency domain conversion module is connected to the digital encoding module; the sampling module is used to sample the audio signal at a preset sampling frequency to obtain a sampled audio signal; the frequency domain conversion module is used to perform Fourier transformation on the sampled audio signal to obtain a frequency domain signal; the digital encoding module is used to perform digital encoding according to the frequency domain signal to obtain an LED rhythm control signal. In an embodiment of the utility model, the sampling rate of the sampling module needs to be less than the digital signal conversion rate of the digital encoding module.

[0058] See also Figure 3 , which is a schematic diagram of an application scenario of a vehicle window glass control system provided by an embodiment of the utility model. Figure 3As shown, the audio acquisition module collects the audio signal output by the vehicle audio output interface through Ethernet at a preset frequency, the sampling module of the main control module samples the audio signal at a preset sampling frequency and resolution (for example, the sampling frequency is 20khz, and the sampling resolution is 12 bits), and the frequency domain conversion module performs Fourier transform on the sampled audio signal, converts it from the time domain to the frequency domain, obtains the real-time frequency and amplitude of the audio signal, and digitally encodes it based on the frequency and amplitude through the digital encoding module to obtain the LED rhythm control signal. The sampling rate of the sampling module is less than the conversion rate of the digital encoding module. The LED driver module can communicate with the main control module through SPI. The LED driver module can use a proprietary chip to control the LED glass. SPI (Serial Peripheral Interface) is a full-duplex serial communication interface commonly used to connect the main control chip with peripheral devices. The SPI interface uses a master-slave mode, in which the host controls the clock and data transmission, and the slave receives the data sent by the host. In the LED driver module, the LED control signal can be sent to the LED driver chip through the SPI interface. As the host of SPI, the main control chip configures and controls the LED driver chip by sending specific commands and data. As the slave of SPI, the LED driver chip receives commands and data sent by the host and controls the LED on and off according to the received signals. Through SPI communication, the LED driver module can be flexibly configured and controlled to provide more functions and effects. For example, different commands and data can be sent through the SPI interface to control the brightness, color, flashing frequency, etc. of the LED.

[0059] In one example, the refresh rate of the LED glass full screen display is greater than 25HZ.

[0060] See also Figure 4 , which is a schematic diagram of another application scenario of a vehicle window glass control system provided by an embodiment of the utility model. Figure 4 As shown, the mobile device transmits the audio signal to the main control module through wireless communication methods such as Bluetooth and WIFI. The sampling module of the main control module samples the audio signal, and the frequency domain transformation module performs Fourier transform on the sampled audio signal, converting it from the time domain to the frequency domain to obtain the real-time frequency and amplitude of the audio signal, and digitally encodes the frequency and amplitude through the digital encoding module to obtain the LED rhythm control signal.

[0061] In a possible implementation, the audio signal receiving module includes: a wireless communication module, which is used to receive the audio signal output by the mobile device. The wireless communication module can be a WiFi communication module or a Bluetooth communication module.

[0062] In one example, the WiFi communication module and the Bluetooth communication module may have a priority order. Figure 5 , Figure 5 Another application scenario diagram of a vehicle window glass control system provided by an embodiment of the utility model, after initializing the Bluetooth communication module, Ethernet, and WiFi communication modules, first determine whether the vehicle entertainment system controls the vehicle system. When it is determined that the vehicle entertainment system does not control the vehicle system, the WiFi communication module is used to receive the audio signal output by the mobile device when the WiFi is connected. The Bluetooth communication module is used to receive the audio signal output by the mobile device when the WiFi is disconnected. Then, according to the received audio signal, the subsequent process is carried out to realize the relevant control of the LED glass rhythm effect.

[0063] In one example, the LED rhythm control signal is a PWM (Pulse Width Modulation) signal, which digitally encodes the level of the analog signal (the frequency domain signal of the sampled audio signal) to control the changes in the color, frequency, etc. of the LED lamp beads in the LED glass.

[0064] In one example, the LED glass includes: two layers of glass plates and an LED lamp bead array disposed between the two layers of glass plates. The LED glass uses glass conductive coating technology and a control system to present a photoelectric display effect. Figure 6 , which is a schematic diagram of an LED lamp bead array provided by an embodiment of the utility model, such as Figure 6 As shown, the LED lamp beads are equivalent to the pattern pixels. According to the LED rhythm signal, the color, lighting frequency, brightness, etc. of each lamp bead are controlled to display different patterns on the car window glass. For example, Figure 6 In the figure, each circle represents an LED lamp bead. The lamp beads with the same filling pattern as 501 are the first group of lamp beads L1, the lamp beads with the same filling pattern as 502 are the second group of lamp beads L2, and the lamp beads with the same filling pattern as 503 are the third group of lamp beads L3. L1, L2, and L3 are lit alternately, and the lit colors are different. The duration and color of each lighting of L1, L2, and L3 are controlled by the LED rhythmic signal.

[0065] See also Figure 7 , which is a structural diagram of another vehicle window glass control system provided by an embodiment of the utility model. The main control module 601 can obtain audio signals through communication modules such as the audio acquisition module 604, Bluetooth 603, wifi 602, Ethernet 605, etc., and generate LED rhythmic control signals according to the audio signals, and control the LED glass 608 to display the rhythmic effect through the LED driving module 606. The main control module can also control other devices in the car, such as lights in the car, through Ethernet 606 and various local gateways 609 in the car, to achieve a rhythmic atmosphere.

[0074] In actual application scenarios, when the vehicle user is playing music, the system can collect the audio signal output by the vehicle audio equipment, and display it in rhythm with the music according to the music played by the audio equipment in the car. In order to ensure the transparency of the car window, image graphic design can be omitted. For example, the LED can be set to a starry sky effect, and a simple three-color LED dot matrix glass with a certain pixel spacing can be used. The rhythm of each LED dot matrix glass can be adjusted according to the rhythm of the audio signal.

[0075] In actual application scenarios, when the vehicle uses LED glass with stronger display, the display content can be more delicate. When the passengers in the car use the in-car entertainment system, that is, when the system collects the audio signal output by the vehicle audio device, or when the passengers use mobile devices such as mobile phones or computers to play games or listen to music, the preset LED glass of the entire car body can display the real scene atmosphere with the music or game scene, making the passengers feel immersive. For example, when a mobile device or in-car entertainment system reads a poem related to bamboo, the bamboo scene corresponding to the current audio signal can be displayed on the preset LED glass of the car body.

The preset window can be at least one of all the glass in the vehicle.

[0080] Thus, passers-by can provide timely assistance to the currently faulty vehicle, increasing the chances of the vehicle owner getting timely assistance. In actual application scenarios, the effects of the call for help can be: patterns, text, etc.
