Description

Technical Field

[0001] This application relates to the field of vehicle cockpit technology, and in particular to a central control display screen for a vehicle cockpit and a vehicle. Background Technology

[0002] As automotive intelligence levels continue to improve, the intelligence level of vehicle cabins has also significantly increased. However, current center console displays in the cabin have relatively limited functionality, typically only providing information display and basic touch interaction. Related technologies have expanded the interactive functions of the center console display by providing external independent ambient lighting and / or physical buttons. However, this disrupts the integrity and simplicity of the interior design. Summary of the Invention

[0003] This application provides a central control display screen for a vehicle cockpit and a vehicle.

[0004] This application provides a central control display screen for a vehicle cockpit, including an ambient lighting module, a button module, and a controller; The ambient lighting module is integrated into the central control display screen. The ambient lighting module includes multiple light strips that can be independently configured with display parameters, and the ambient lighting module has multiple working modes. The button module is integrated into the non-display area of ​​the central control display screen; The controller is communicatively connected to the vehicle infotainment system in the vehicle cabin. The controller is configured to configure the display parameters of the ambient lighting module in each working mode based on a first configuration signal, and / or control the ambient lighting module to operate in the target working mode with corresponding lighting effects based on the control signals of the vehicle infotainment system. The controller is also configured to configure the touch function and / or touch mode of the button module based on a second configuration signal.

[0005] Thus, in this embodiment, the ambient lighting module and touch buttons are integrated into the central control display screen, improving space utilization and system integration, maintaining the integrity and simplicity of the vehicle interior, and avoiding a complex and cumbersome aftermarket installation process. The ambient lighting module can be linked with the vehicle's status, improving driving safety. The button module supports customized configurations of touch functions and touch methods, enriching the physical function configurations of the buttons and effectively improving interaction efficiency and user experience. The central control display screen of this embodiment is adapted to vehicles equipped with a smart cockpit.

[0006] In some embodiments, the ambient lighting module is integrated into the inner side of the front panel border of the central control display screen; and / or Each set of light strips includes RGB tri-color light strips; and / or The number of light strips is four groups, and each group of RGB three-color light strips is respectively set on one side of the frame.

[0007] Thus, by concealing the light strip 11 within the surrounding frame, the light shines through evenly and softly, enhancing visual comfort and the overall aesthetics of the interior while maintaining the clean look of the central control display screen. The use of four sets of red, green, and blue tri-color light strips distributed across the four frames provides the hardware foundation for independent control of multiple areas, allowing the central control display screen to display rich color variations around its perimeter and better adapt to various operating modes.

[0008] In some embodiments, the central control display screen further includes an ambient light driving module, which is electrically connected to the controller and the ambient light module respectively; the controller is configured to drive the corresponding light strip to operate according to the configured display parameters by controlling the ambient light driving module.

[0009] Thus, by introducing an ambient light driver module, the driving capability of the lighting system is effectively improved, ensuring a stable and sufficient power supply for multiple light strips and avoiding uneven brightness or color deviation caused by insufficient driving. At the same time, the clear division of labor between the controller and the ambient light driver module reduces the load and heat generation of the main control chip, minimizes signal crosstalk, ensures the accuracy of the light strip display parameters, and improves the overall system stability and lighting interaction experience.

[0010] In some implementations, the operating modes include at least two of the following: ambient lighting mode, vehicle multimedia audio synchronization rhythm mode, racing mode, and / or collision warning mode.

[0011] Thus, by setting multiple different working modes, the ambient lighting on the central control display screen is no longer limited to a single color display, but becomes a multi-dimensional information interaction medium. At least two of the required modes ensure the system has multi-scenario interactive capabilities while also providing flexibility in the vehicle's configuration. The lighting, synchronized with cabin sounds and multimedia audio, enhances the immersive audiovisual experience and entertainment atmosphere inside the vehicle. The linkage between the lighting and vehicle speed and surrounding information provides intuitive overspeed warnings and collision avoidance alerts without deviating from the driver's line of sight, effectively improving driving safety and enriching the dimensions of human-machine interaction in the cabin.

[0012] In some embodiments, the central control display screen further includes an audio processing module and a video display deserialization module; In the ambient lighting mode, the audio processing module receives the cabin audio signal picked up by the microphone and transmits it to the controller. The controller then controls the ambient lighting driver module based on the cabin audio signal; and / or In the vehicle multimedia audio synchronous rhythm mode, the video display deserialization module receives the audio and video data stream played by the vehicle multimedia host, separates the audio stream, and transmits it to the controller. The controller controls the ambient light driving module based on the audio stream.

[0013] This enables compatible control of different audio sources, supporting both real-time pickup and linkage of human voices within the cockpit and synchronized rhythm of multimedia music. The video display deserialization module locally separates and parses high-speed serial data, reducing data transmission latency, ensuring synchronization between lighting changes and music rhythm, and enhancing the cockpit's audiovisual immersion and the reliability of system response.

[0014] In some implementations, in the racing mode, the controller is configured to acquire the current vehicle speed collected by the vehicle system and / or vehicle sensors, convert the current speed into a rhythm frequency and display color, and control the ambient light driving module to operate. Specifically, when the current speed is within a speed limit, the ambient light module displays a first preset color, and the running horse rhythm frequency increases with increasing vehicle speed within a preset frequency range. When the current speed exceeds the speed limit, the ambient light module displays a second preset color, and the running horse rhythm frequency is greater than the preset frequency. The first preset color and the second preset color are different.

[0015] By combining vehicle speed data with visual lighting, drivers can perceive their current speed using only their peripheral vision, reducing the frequency of checking the instrument panel. In cases of speeding, sudden color changes and a significant increase in frequency effectively attract the driver's attention, serving as a speeding warning and improving driving safety. This also enriches the interactive dimensions of the central control display screen in terms of vehicle dynamic feedback.

[0016] In some implementations, in the collision avoidance warning mode, the controller is configured to acquire vehicle perimeter information collected by the vehicle infotainment system, vehicle radar system, and / or vehicle imaging system, the vehicle perimeter information including the position of objects approaching the vehicle, and control the ambient lighting module to display a warning based on the position; and / or When an object is detected approaching the vehicle, the controller controls the light strip on the side corresponding to the object's approach direction to enter the collision avoidance warning mode, while controlling the light strips on other sides to maintain their current operating mode. Specifically, if an object approaches from the left side of the vehicle, the controller controls the light strip on the left side of the ambient lighting module located on the central control display screen to trigger the warning light effect; and / or if an object approaches from the right side of the vehicle, the controller controls the light strip on the right side of the ambient lighting module located on the central control display screen to trigger the warning light effect; and / or if an object approaches from the rear of the vehicle, the controller controls the light strip on the ambient lighting module located below the central control display screen to trigger the warning light effect; and / or if an object approaches from the front of the vehicle, the controller controls the light strip on the ambient lighting module located above the central control display screen to trigger the warning light effect.

[0017] In this way, by visually mapping the physical spatial orientation around the vehicle to the orientation of the bezel around the central control display screen, only the warning light on the corresponding side is triggered when an object is detected approaching from a specific direction, providing the driver with a clear and directional hazard warning. The driver can perceive the change in light and determine the direction of the hazard source with their peripheral vision, without having to look away from the screen, thus shortening reaction time. At the same time, the design of only the corresponding side light strip entering warning mode while the other sides remain in their current operating mode highlights the key warning point while avoiding visual fatigue and startling sensations caused by full-screen flashing, thus balancing driving safety warnings with cabin comfort.

[0018] In some embodiments, the controller is also configured to control the operation of the ambient lighting module according to preset rules; and / or The controller is also configured to: Configure the ambient lighting mode as the default mode, and when the vehicle system detects that multimedia is playing, use the vehicle multimedia audio synchronization rhythm mode as the basic display mode. When the basic display mode is running, if an object is detected approaching the vehicle, the collision avoidance warning mode is triggered; if no object is detected approaching and the vehicle speed exceeds the speed limit, the racing mode is triggered. When the triggering conditions for the collision avoidance warning mode or the racing mode disappear, the ambient light module is controlled to return to the basic display mode.

[0019] In this way, the pre-defined scheduling logic effectively avoids display conflicts caused by concurrent multi-mode operation, ensuring that functions related to driving safety, such as collision avoidance warning and overspeed warning, have higher execution priority. Simultaneously, the system automatically reverts to entertainment mode after the warning status is lifted, requiring no manual user intervention. This balances driving safety alerts with the daily entertainment experience in the cabin, improving the system's automation level and the consistency of human-computer interaction.

[0020] In some embodiments, the button module is integrated into the inner sides of the left and right bezels of the central control display screen, and the button module includes multiple capacitive touch buttons and a capacitive touch acquisition module; and / or The touch control methods include single-point touch, multi-point touch and swipe touch. The single-point touch includes single-click touch, double-click touch or long-press touch. The multi-point touch includes a combination of multiple buttons. The swipe touch includes swiping along the edge of the central control display screen in a preset direction. The capacitive touch acquisition module is configured to acquire the status of the capacitive touch button, generate a message, and send it to the controller.

[0021] Thus, by integrating the capacitive touch buttons inside the bezel, the problems of poor dust and water resistance and easy wear and tear of external physical buttons are overcome, improving the overall reliability of the system. The hidden design maintains the simplicity of the central control display screen's appearance and does not occupy the display area. At the same time, it supports various gesture operations such as single-point touch, multi-point touch, and swipe touch, allowing users to operate blindly according to their personal habits, realizing personalized access to functions, enriching the dimensions of cockpit human-machine interaction and operational efficiency.

[0022] This application also provides a vehicle including the central control display screen as described above.

[0023] Additional aspects and advantages of embodiments of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of this application. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0026] As automotive intelligence continues to improve, the intelligence level of vehicle cabins has also significantly increased. However, current central control displays in the cabin are relatively limited in function, typically only providing information display and basic touch interaction, making it difficult to create an immersive in-car audiovisual atmosphere. To enhance the user experience, vehicle manufacturers or accessory manufacturers provide ambient lighting and physical buttons that work with the central control display. However, these hardware components are usually separate units. Understandably, this split design not only occupies extra space in the vehicle and disrupts the integrity and simplicity of the interior design, but also makes installation and operation very inconvenient. At the same time, aftermarket ambient lighting cannot be linked with vehicle sensors, such as speed radar and imaging systems. In addition, traditional physical buttons may have drawbacks such as poor dust and water resistance, easy wear and tear leading to malfunction, and fixed and limited functions, failing to meet increasingly diverse interaction needs.

[0027] Based on the above issues, please refer to Figure 1 This application provides a central control display screen 100 for a vehicle cockpit. The central control display screen 100 includes an ambient lighting module 10, a button module 20, and a controller 30.

[0028] The ambient lighting module 10 is integrated into the central control display screen 100. The ambient lighting module 10 includes multiple light strips 11 that can be independently configured with display parameters. The ambient lighting module 10 has multiple working modes.

[0029] The button module 20 is integrated into the non-display area of ​​the central control display screen 100.

[0030] The controller 30 is connected to the vehicle infotainment system in the vehicle cabin. The controller 30 is configured to configure the display parameters of the ambient lighting module 10 in each working mode based on a first configuration signal, and / or control the ambient lighting module 10 to operate in the target working mode with corresponding lighting effects based on the control signals of the vehicle infotainment system.

[0031] The controller 30 is also configured to configure the touch function and / or touch mode of the button module 20 based on the second configuration signal.

[0032] This application also provides a vehicle, which includes a central control display screen 100.

[0033] Specifically, the central control display screen 100 of this application embodiment is adapted to a vehicle 1000 equipped with a smart cockpit. The central control display screen 100 of this application embodiment directly integrates the ambient lighting module 10 and the button module 20 onto the central control display screen 100 body, and sets up a controller 30 that communicates with the vehicle's infotainment system in the vehicle cockpit. The controller 30 uniformly receives configuration signals and control signals, enabling multi-mode linkage display of ambient lighting and personalized customization of button functions.

[0034] The central control display screen 100 is an in-vehicle device that integrates display and interactive functions, including an ambient lighting module 10, a button module 20, and a controller 30.

[0035] The ambient lighting module 10 is a lighting system comprising multiple sets of light strips and related driving components. This module is integrated inside the central control display screen 100, for example, it can be located inside the bezel around the display screen. It should be noted that "integrated" means that the components are directly built into the main structure of the central control display screen, without the need for additional external connections.

[0036] The ambient lighting module 10 includes multiple light strips 11 with independently configurable display parameters. Each light strip 11 is a light-emitting strip that can emit various colors of light, such as red, green, and blue light strips. These strips are distributed on different sides of the frame and their color and brightness parameters can be set independently. Display parameters refer to the visual performance attributes of the light, such as color, brightness, and flicker frequency.

[0037] The ambient lighting module 10 features multiple operating modes, which refer to different lighting states, such as ambient lighting mode with audio pickup, vehicle multimedia audio synchronization mode, racing mode, and collision warning mode. Multiple light strips 11 can be independently configured and offer various operating modes, enabling the ambient lighting module 10 to interact in real-time with vehicle status such as speed and surrounding environmental information. This creates an immersive in-car atmosphere while providing overspeed warning and collision warning functions.

[0038] The button module 20 is an input device for receiving user touch operations. It is integrated into the non-display area of ​​the central control display screen. The non-display area refers to the parts of the display screen such as the bezel that are not used for the main screen display. Specifically, it can be located inside the left or right bezel.

[0039] The controller 30 is the main control chip inside the central control display screen, responsible for data processing and command transmission and reception. The controller 30 communicates with the vehicle's infotainment system in the vehicle cabin. The infotainment system is the host system responsible for vehicle data interaction and function scheduling. The communication connection refers to the signal transmission channel established through a bus or other means.

[0040] During operation, the controller 30 can be configured to configure the display parameters of the ambient lighting module 10 in each working mode based on the first configuration signal. The first configuration signal is instruction data used to set the lighting parameters, which can usually be issued by the user through a terminal, including a mobile terminal used in conjunction with the vehicle and / or the vehicle's infotainment system. The user can configure the display parameters and generate the first configuration signal through an application installed on the terminal or a small program loaded on the terminal.

[0041] The controller 30 can also be configured to control the ambient lighting module 10 based on the control signals from the vehicle infotainment system to operate in a target working mode with corresponding lighting effects. The control signal is an instruction issued by the vehicle infotainment system to trigger the lighting operation state, the lighting effect is the brightness, color and dynamic change of the light, and the target working mode is a certain ambient lighting working mode currently being executed.

[0042] The controller 30 can also be configured to configure the touch functions and / or touch methods of the button module 20 based on a second configuration signal. The second configuration signal is instruction data used to set the button functions. Touch functions are the specific actions performed by the buttons, such as starting navigation, switching music, adjusting air conditioning, adjusting brightness, adjusting volume, etc., while touch methods are the gestures used to trigger the buttons, such as clicking or swiping. Similarly, the second configuration signal can be sent by the user through a terminal, including a mobile terminal used in conjunction with the vehicle and / or the vehicle's infotainment system. The user can configure the touch functions and / or touch methods and generate the second configuration signal through applications installed on the terminal or small programs loaded on the terminal. The button module 20 of this embodiment supports custom configuration of touch functions and touch methods, supports rich touch gestures, and enables one-click access to frequently used functions.

[0043] In terms of overall physical connection, the ambient lighting module 10 and the button module 20 are electrically connected to the controller 30 through internal circuitry. The controller 30 is connected to the vehicle infotainment system via a communication bus. When the user operates the system or the vehicle infotainment system status changes, the controller 30 receives the corresponding signal, performs internal logic operations, and sends a drive command to the ambient lighting module 10 to display the corresponding lighting effect, or receives the touch message from the button module 20 and forwards it to the vehicle infotainment system to execute the corresponding function.

[0044] Thus, in this embodiment, the ambient lighting module 10 and the button module 20 are integrated into the central control display screen 100, improving space utilization and system integration, maintaining the integrity and simplicity of the vehicle interior, and avoiding a complex and cumbersome aftermarket installation process. The ambient lighting module 10 can be linked with the vehicle status, improving driving safety. The button module 20 supports customizable configurations of touch functions and touch methods, enriching the physical function configurations of the buttons and effectively improving interaction efficiency and user experience. The central control display screen 100 of this embodiment is compatible with vehicles 1000 equipped with a smart cockpit.

[0045] Please see Figure 2 In some embodiments, the ambient lighting module 10 is integrated into the inner side of the front panel of the central control display screen 100; and / or each group of light strips 11 includes RGB three-color light strips; and / or the number of light strips 11 is four groups, with each group of RGB three-color light strips respectively arranged on one side of the frame.

[0046] Specifically, it can be understood that in practical applications, the placement of the ambient lighting module 10 and the selection of the light strip 11 directly affect the final visual presentation effect and the manufacturability of the system. If the light strip 11 is placed arbitrarily or improperly selected, problems such as uneven light emission, local light leakage, or damage to the overall appearance design of the central control display screen may easily occur. In addition, if the number of light strips is not set reasonably, it may be difficult to achieve independent linkage control of multiple areas, and it may be unable to meet the needs of differentiated lighting effects in complex scenarios, such as directional collision avoidance warning, thus affecting the user's immersive experience and driving safety.

[0047] In this embodiment, the ambient lighting module 10 is integrated into the inner side of the front panel of the central control display screen 100. At the same time, the number of light strips 11 is set to four groups. Each group of light strips 11 uses red, green and blue light strips and is respectively set on the upper, lower, left and right sides of the frame, corresponding to the front, rear, left and right directions of the vehicle. This creates a surrounding uniform light-emitting system, which not only ensures the concealment and aesthetics of the light, but also supports independent control in multiple directions.

[0048] The front panel refers to the surface of the central control display screen 100 facing the driver and passengers. The surrounding frame refers to the outer frame structure around the display area, and the inner side refers to the internal space of the frame close to the display area and facing away from the user's line of sight. The ambient lighting module 10 is integrated into the inner side of the front panel's surrounding frame, meaning the light-emitting components are hidden inside the frame, allowing light to pass through the frame's light guide structure or gaps evenly. This layout better adapts to various operating modes such as audio pickup, rhythm, racing warning, and collision warning. For example, in collision warning mode, the corresponding side light strip can be illuminated for a flashing alarm, further enhancing the intuitiveness of the interaction, the richness of functions, and the reliability of the system.

[0049] Each set of light strips 11 includes red, green and blue tri-color light strips. The red, green and blue tri-color light strips refer to light strips integrated with red, green and blue light-emitting chips. By controlling the mixing ratio of these three primary colors, a variety of colors of light can be produced.

[0050] The number of light strips 11 can be four sets, which are respectively set on the top, bottom, left and right sides of the four-sided frame.

[0051] These four sets of red, green, and blue LED strips are connected to the drive output terminal of the controller 30 via internal circuit board wiring. During operation, the controller 30 can independently send drive signals to these four sets of LED strips, configuring display parameters such as color brightness and flashing frequency for each LED strip distributed in the four directions (up, down, left, and right), thereby achieving independent lighting effects and coordinated control in four directions.

[0052] Thus, by concealing the light strip 11 within the surrounding frame, the light shines through evenly and softly, enhancing visual comfort and the overall aesthetics of the interior while maintaining the clean appearance of the central control display screen 100. The use of four sets of red, green, and blue tri-color light strips distributed around the four edges provides the hardware foundation for independent control of multiple areas, enabling the central control display screen 100 to display rich color variations around its perimeter and better adapt to various operating modes.

[0053] In some embodiments, the central control display screen 100 further includes an ambient light driving module 40, which is electrically connected to both the controller 30 and the ambient light module 10. The controller 30 is configured to control the ambient light driving module 40 to drive the corresponding light strip 11 to operate according to the configured display parameters.

[0054] Specifically, the central control display integrates an ambient lighting module 10 to enhance the interactive experience. However, due to the limited voltage and current driving capabilities of the main control chip's output pins, directly driving multiple light strips by the main control chip may result in insufficient power supply, leading to decreased light brightness or color distortion. Furthermore, the direct parallel output of multiple light signals can easily cause signal crosstalk, making it difficult to ensure that each light strip operates strictly according to the preset display parameters, thus affecting the overall ambient rendering effect and system reliability.

[0055] In this embodiment, an ambient light driver module 40 is introduced between the controller 30 and the ambient light module 10 to form a two-level control architecture. The controller is responsible for logic operations and instruction issuance, while the driver module is responsible for power amplification and execution drive, ensuring stable operation of the lighting.

[0056] The ambient light driver module 40 is a hardware circuit module used to receive control signals and provide sufficient power current to illuminate the light strip. It typically includes a constant current source or constant voltage source chip and a signal amplification circuit. The electrical connection can be a physical electrical path established through conductive media such as wires or printed circuit board traces.

[0057] The input terminal of the ambient light driver module 40 can be connected to the control output pin of the controller, and the output terminal of the ambient light driver module 40 is connected to each group of light strips 11 in the ambient light module 10. During operation, the controller 30 generates corresponding lighting control commands based on configuration signals or vehicle control signals and sends these commands to the ambient light driver module 40. After receiving the command, the ambient light driver module 40 converts it into a current or voltage signal that can drive the light strips to emit light, and controls the corresponding light strip 11 to operate according to the configured display parameters such as color brightness and flashing frequency. With this architecture, the controller 30 only needs to process low-power logic signals and does not need to undertake high-power output tasks.

[0058] In this arrangement, by introducing the ambient light driving module 40, the driving capability of the light system is effectively improved, ensuring that multiple sets of light strips 11 can obtain stable and sufficient power supply, and avoiding the problems of uneven brightness or color deviation caused by insufficient driving. At the same time, the controller 30 and the ambient light driving module 40 have a clear division of labor, which reduces the load and heat generation of the main control chip, reduces signal crosstalk, ensures the accuracy of the execution of light strip display parameters, and improves the stability of the overall system and the light interaction experience.

[0059] In some embodiments, the working modes include at least two of a sound pickup ambient light mode, an in-vehicle infotainment multimedia audio synchronous rhythm mode, a racing mode and / or an anti-collision warning mode.

[0060] Specifically, in the related art, vehicle-mounted ambient lights often only have simple lighting or single color change functions, and cannot be linked with the in-vehicle audio playback status and the vehicle driving environment. This isolated light display method can hardly meet the diverse requirements of drivers and passengers for an immersive audio-visual experience. Meanwhile, when the external environment is complex and changeable, it cannot use the lights to provide intuitive driving safety assistance prompts, which limits the performance of the interaction function of the central control display screen.

[0061] In the embodiments of the present application, the working modes of the ambient light module 10 include at least two of the sound pickup ambient light mode, the in-vehicle infotainment multimedia audio synchronous rhythm mode, the racing mode and the anti-collision warning mode. By setting multiple working modes, the ambient light can respond to different trigger sources to realize multi-scenario linked display.

[0062] Wherein, the sound pickup ambient light mode is a working state in which the controller 30 controls the light strips 11 to change with the sound frequency and rhythm based on the collected internal sound signal of the cockpit.

[0063] The in-vehicle infotainment multimedia audio synchronous rhythm mode is a working state in which the controller 30 controls the light strips to perform rhythm display based on the audio signal separated from the audio and video data stream played by the vehicle infotainment host.

[0064] The racing mode is a working state in which the controller 30 acquires the current driving speed of the vehicle, converts the speed value into the rhythm frequency and display color of the light strips for display.

[0065] The anti-collision warning mode is a working state in which the controller 30 acquires the surrounding environment information of the vehicle and controls the light strips in the corresponding direction to flash for alarm when an obstacle is detected approaching.

[0066] During operation, any two or more combinations of the above four working modes can be selected for configuration and application, and it is not limited to a single mode or must have all four modes at the same time. This allows for flexible system design, and the corresponding mode combination can be selected for installation according to the configuration requirements or cost considerations of different vehicle models.

[0067] In some examples, the controller 30 has pre-set logic for determining and switching between multiple modes. When someone is speaking or making sounds inside the cockpit, the controller 30 receives a signal from the audio processing module and enters the ambient lighting mode.

[0068] When the vehicle system starts playing multimedia audio and video, the controller 30 receives the separated audio stream and switches to the vehicle multimedia audio synchronous rhythm mode.

[0069] During vehicle operation, the controller 30 monitors vehicle speed data in real time. If the vehicle speed is within the speed limit, it controls the light strip 11 to pulsate at a frequency that changes with the speed. If the vehicle speed exceeds the preset range, it triggers racing mode, changes the light color and increases the pulsation frequency to alert the driver.

[0070] Meanwhile, the controller 30 continuously monitors the surrounding environment. Once it detects an object approaching from a specific location, it immediately triggers the collision avoidance warning mode, illuminating the corresponding side light strip as a warning. Since it is equipped with at least two operating modes, these modes can automatically switch and overlap according to preset priorities. For example, when the multimedia rhythm mode is running, if an obstacle is detected approaching, the collision avoidance warning mode will be switched first.

[0071] Thus, by setting multiple different working modes, the ambient lighting on the central control display screen is no longer limited to a single color display, but becomes a multi-dimensional information interaction medium. At least two of the required modes ensure the system has multi-scenario interactive capabilities while also providing flexibility in the vehicle's configuration. The lighting, synchronized with cabin sounds and multimedia audio, enhances the immersive audiovisual experience and entertainment atmosphere inside the vehicle. The linkage between the lighting and vehicle speed and surrounding information provides intuitive overspeed warnings and collision avoidance alerts without deviating from the driver's line of sight, effectively improving driving safety and enriching the dimensions of human-machine interaction in the cabin.

[0072] Please see Figure 4 In some embodiments, the central control display screen 100 further includes an audio processing module 50 and a video display deserialization module 60. In ambient lighting mode, the audio processing module 50 receives cabin audio signals picked up by the microphone and transmits them to the controller 30. The controller 30 controls the ambient lighting drive module 40 based on the cabin audio signals; and / or In the vehicle multimedia audio synchronous rhythm mode, the video display deserialization module 60 receives the audio and video data stream played by the vehicle multimedia host, separates the audio stream, and transmits it to the controller 30. The controller 30 controls the ambient light driver module 40 based on the audio stream.

[0073] Specifically, it's understandable that as in-cabin entertainment systems become more sophisticated, users' demands for in-car audio-visual ambiance are increasing. In related technologies, ambient lighting often relies on a single sound source to achieve audio sync, such as only being able to synchronize with media music played through the vehicle's head unit, or only capturing conversations within the vehicle, lacking a comprehensive processing mechanism for different audio sources. Furthermore, the high-definition audio and video data transmitted from the vehicle's head unit to the central control display screen typically uses a serial bus. If the central control display screen cannot effectively deserialize and separate the audio data, the audio sync function will be difficult to implement or will suffer from audio-visual asynchrony and high latency.

[0074] In this embodiment, an audio processing module 50 and a video display deserialization module 60 are added to the central control display screen 100, which are used to process the sound directly picked up in the cabin and the multimedia audio and video data sent by the vehicle host, respectively, so as to realize the linkage control of ambient lights under different audio sources.

[0075] In this embodiment, the central control display screen 100 further includes an audio processing module 50 and a video display deserialization module 60. The audio processing module 50 is a hardware circuit unit for receiving, filtering, amplifying, and converting audio signals into digital signals. The video display deserialization module 60 is a hardware module for receiving serial audio and video data sent by the vehicle's main unit and deserializing it back into parallel audio and video signals.

[0076] A microphone is a sound-to-electrical conversion device used to collect sound within the cabin. The cabin audio signal is data collected by the microphone that reflects the sound characteristics within the cabin. The vehicle's multimedia host is an in-vehicle computing and output device responsible for playing audio and video media content.

[0077] Audio and video data streams are continuous sequences of digital signals containing both video and audio data. Audio streams are digital signals containing only audio information extracted from audio and video data streams.

[0078] The input of the audio processing module 50 is connected to the microphone, and the output is connected to the communication interface of the controller 30. The input of the video display deserialization module 60 is connected to the vehicle multimedia host via a high-speed serial bus, its video output is connected to the display panel of the central control display screen 100, and its audio output is connected to the controller 30.

[0079] During operation, when in ambient lighting mode, the microphone collects the voices of the driver and passengers. The audio processing module 50 receives the audio signal in the cabin picked up by the microphone, amplifies and digitizes it, and then transmits it to the controller 30. Based on the frequency and amplitude of the audio signal in the cabin, the controller 30 controls the ambient lighting drive module 40 to drive the light strip 11 to produce corresponding brightness and color changes.

[0080] When in the vehicle multimedia audio synchronous rhythm mode, the video display deserialization module 60 receives the audio and video data stream played by the vehicle multimedia host, performs deserialization processing on the data, separates the audio stream, and transmits it to the controller 30. Based on the rhythm and volume information of the audio stream, the controller 30 controls the ambient light drive module 40 to drive the light strip 11 to perform synchronous rhythm display.

[0081] This enables compatible control of different audio sources, supporting both real-time pickup and linkage of human voices within the cockpit and synchronized rhythm of multimedia music. The video display deserialization module locally separates and parses high-speed serial data, reducing data transmission latency, ensuring synchronization between lighting changes and music rhythm, and enhancing the cockpit's audiovisual immersion and the reliability of system response.

[0082] In some implementations, in racing mode, the controller 30 is configured to acquire the current vehicle speed collected by the vehicle system and / or vehicle sensors, convert the current speed into a rhythm frequency and display color, and control the ambient light drive module to operate. Specifically, when the current speed is within the speed limit range, the ambient light module 10 is controlled to display a first preset color and the running horse rhythm frequency increases with the vehicle speed within a preset frequency range. When the current speed exceeds the speed limit range, the ambient light module 10 is controlled to display a second preset color and the running horse rhythm frequency is greater than the preset frequency. The first preset color and the second preset color are different.

[0083] Specifically, it's understandable that drivers need to constantly monitor their speed to avoid speeding. However, some technologies require drivers to frequently shift their gaze to check the speedometer, posing a safety hazard. Furthermore, in-vehicle ambient lighting systems are primarily used for entertainment and cannot be effectively integrated with the vehicle's driving status, thus failing to fulfill their function as a driver assistance system.

[0084] In this embodiment, by associating vehicle speed with the rhythmic frequency and display color of ambient lights, the dynamic effect of the lights is adjusted according to the vehicle speed when the vehicle speed is normal, and the color is changed and the flashing frequency is increased when speeding, thereby providing the driver with intuitive vehicle speed perception and speeding warning.

[0085] As mentioned above, the racing mode is the working state in which the controller 30 obtains the current driving speed of the vehicle and converts the speed value into the rhythm frequency and display color of the light strip for display. In other words, in the racing mode, the controller 30 can adjust the ambient light display status in real time according to the vehicle's driving speed.

[0086] Vehicle sensors are hardware devices used to collect data on the operating status of vehicles. The current vehicle speed refers to the linear velocity of the vehicle in real time.

[0087] Rhythm frequency refers to the rate at which the light color changes or the illuminated position moves cyclically. Display color refers to the specific color emitted by the light strip.

[0088] Speed ​​limits are pre-defined legal or safe driving speed thresholds, such as 60 km / h.

[0089] The first preset color is the system's default display color when the vehicle speed is within the limit. The "marquee rhythm frequency" refers to the cycle speed at which the lights illuminate sequentially in a marquee format. The preset frequency is a standard range for the marquee's movement speed. The second preset color is the system's warning color when the vehicle speed exceeds the limit.

[0090] The controller 30 connects to the vehicle's infotainment system and sensors via the vehicle communication bus to acquire real-time data on the vehicle's current speed. When entering racing mode, the controller 30's internal program converts the current speed into rhythm frequency and display color parameters, and generates corresponding control commands to send to the ambient light driver module 40.

[0091] Specifically, when the vehicle's current speed is within the speed limit range, the controller 30 controls the ambient light module 10 to display the first preset color, and makes the running light rhythm frequency increase with the vehicle speed within the preset frequency, that is, the faster the vehicle speed, the faster the light runs.

[0092] When the vehicle's current speed exceeds the speed limit, the controller 30 controls the ambient lighting module 10 to display a second preset color and controls the running light frequency to be higher than a preset frequency to create a strong visual stimulus. The first preset color and the second preset color are different; for example, the former is blue and the latter is red, thus clearly distinguishing between normal driving and speeding. It should be noted that the specific colors of the first and second preset colors are not limited here. The first and second preset colors need to be different, and the second preset color only needs to serve a warning effect; users can set them according to their needs.

[0093] By combining vehicle speed data with visual lighting, drivers can perceive their current speed using only their peripheral vision, reducing the frequency of checking the instrument panel. In cases of speeding, sudden color changes and a significant increase in frequency effectively attract the driver's attention, serving as a speeding warning and improving driving safety. This also enriches the interactive dimensions of the central control display screen in terms of vehicle dynamic feedback.

[0094] In some implementations, in collision avoidance warning mode, the controller 30 is configured to acquire vehicle perimeter information collected by the vehicle infotainment system, vehicle radar system, and / or vehicle imaging system, including the location of objects approaching the vehicle, and control the ambient lighting module 10 to display a warning based on the location; and / or When an object is detected approaching the vehicle, the controller 30 controls the light strip 11 on the side corresponding to the object's approach direction to enter the collision avoidance warning mode, and controls the light strips 11 on other sides to maintain their current working mode. Specifically, when an object approaches on the left side of the vehicle, the controller 30 controls the light strip 11 on the left side of the ambient lighting module 10 located on the central control display screen 100 to trigger the warning light effect, and / or when an object approaches on the right side of the vehicle, the controller 30 controls the light strip 11 on the right side of the ambient lighting module 10 located on the central control display screen 100 to trigger the warning light effect, and / or when an object approaches at the rear of the vehicle, the controller 30 controls the light strip 11 below the central control display screen 100 in the ambient lighting module 10 to trigger the warning light effect, and / or when an object approaches at the front of the vehicle, including typical scenarios such as following too closely to the vehicle in front or a pedestrian approaching in front of the vehicle, the controller 30 controls the light strip 11 above the central control display screen 100 in the ambient lighting module 10 to trigger the warning light effect.

[0095] Specifically, with the increase in vehicle ownership and the increasing complexity of driving environments, drivers often have numerous blind spots while driving, making it difficult to fully and promptly detect vehicles or pedestrians approaching from the sides and rear. In related technologies, in-vehicle warning systems mostly rely on audio prompts or text and image prompts on the central control display screen. However, these methods are not intuitive enough and require the driver to shift their gaze to check the screen, resulting in short reaction time in emergency situations and increasing the risk of collisions. Meanwhile, ambient lighting in related technologies is primarily used for creating an entertainment atmosphere, failing to fully utilize its role in assisting driving safety.

[0096] In this embodiment, collision avoidance warning is based on ambient light orientation mapping. By acquiring information about the vehicle's surrounding environment, when an object is detected approaching, the light strip 11 on the side of the central control display screen 100 corresponding to the direction of the approaching object is triggered to activate a warning light effect, thereby providing a directional hazard warning and helping the driver quickly detect potential threats without shifting their gaze.

[0097] In collision avoidance warning mode, the controller 30 is configured to acquire information about the vehicle's surroundings, including the location of objects approaching the vehicle, and control the ambient lighting module 10 to display a warning based on that location.

[0098] Vehicle perimeter information can be acquired through vehicle infotainment systems, vehicle radar systems, and / or in-vehicle imaging systems. Vehicle radar systems are used to detect the distance and relative speed of obstacles around the vehicle. In-vehicle imaging systems are used to acquire images of the vehicle's surrounding environment. Vehicle perimeter information is data obtained by radar or imaging systems that reflects the state of the environment around the vehicle and the positions of objects.

[0099] Objects around a vehicle are entities existing within a certain range outside the vehicle that may affect driving safety, such as other vehicles or pedestrians. Orientation refers to the spatial position of an object relative to the vehicle. Warning displays alert the driver to potentially hazardous conditions through specific colors or flashing lights.

[0100] The controller 30 can connect to the radar system and imaging system via the vehicle communication bus to obtain detection data, and at the same time, it can independently control each group of light strips 11 by controlling the ambient light drive module.

[0101] During operation, when an object is detected approaching the vehicle, the controller 30 controls the light strip 11 on the side corresponding to the direction of the approaching object to enter the collision avoidance warning mode, while controlling the light strips 11 on the other sides to maintain their current operating mode. The direction of the approaching object is the specific direction in which an object is detected approaching the vehicle. The corresponding side is the side of the central control display screen 100 that corresponds to the direction of the approaching object in spatial mapping. The other sides are the remaining sides of the central control display screen 100 excluding the corresponding side. The current operating mode is a certain operating mode that the ambient light module 10 was executing before the collision avoidance warning was triggered.

[0102] Specifically, when an object approaches from the left side of the vehicle, the controller 30 controls the light strip 11 located on the left side of the central control display screen 100 in the ambient lighting module 10 to trigger a warning light effect. The left side of the vehicle refers to the area to the left of the vehicle's direction of travel. The warning light effect is a light display used for warning purposes, such as a yellow or red flashing light.

[0103] When an object approaches from the right side of the vehicle, the controller 30 controls the light strip 11 located to the right of the central control display screen 100 in the ambient lighting module 10 to trigger a warning lighting effect. The right side of the vehicle refers to the area to the right of the vehicle's direction of travel.

[0104] When an object approaches the rear of the vehicle, the controller 30 controls the light strip 11 located below the central control display screen 10 in the ambient lighting module 10 to trigger a warning lighting effect. The rear of the vehicle is the area behind the vehicle.

[0105] When an object approaches the front of the vehicle, the controller 30 controls the light strip 11 located above the central control display screen 10 in the ambient lighting module 10 to trigger a warning lighting effect. The front of the vehicle refers to the area in front of the vehicle.

[0106] In this way, by visually mapping the physical spatial orientation around the vehicle to the orientation of the four bezels of the central control display screen 100, only the warning light effect on the corresponding side is triggered when an object is detected approaching from a specific direction, providing the driver with a clear and intuitive hazard warning. The driver can perceive the change in light and determine the direction of the hazard source with peripheral vision, without having to shift their gaze to the screen, thus shortening reaction time. At the same time, the design of only the corresponding side light strip 11 entering warning mode while the other sides remain in their current operating mode highlights the key warning point while avoiding visual fatigue and startling sensations caused by full-screen flashing, thus balancing driving safety warnings with cabin comfort.

[0107] Please see Figure 5 The following example explains the control logic of the ambient lighting module 10 in each working mode: The ambient lighting module 10 supports four working modes: ambient lighting mode with sound pickup, racing mode, collision warning mode, and vehicle multimedia audio synchronization rhythm mode. The main control module (controller 30) responds to the mode setting command issued by the vehicle system, selects the corresponding working mode, and controls the RGB driver module (ambient lighting driver module 40) to drive the light strip 11 to run according to the signal processing link corresponding to the mode.

[0108] In ambient lighting mode, the system uses ambient audio picked up within the cabin as the trigger source. The microphone collects sound signals from the cabin in real time. The audio module (audio processing module 50) amplifies, filters, and performs analog-to-digital conversion on the audio signals, then transmits the processed audio data to the main control module via the I2S bus. The main control module generates lighting drive parameters in real time based on the frequency and amplitude characteristics of the audio signal and outputs PWM control signals to the RGB drive module. The RGB drive module then drives the light strip to display a rhythmic lighting effect that changes with the audio beat, based on the control signals.

[0109] In racing mode, the system uses the vehicle's real-time speed as the trigger source. The main control module obtains the vehicle's current speed information through the vehicle communication bus, converts the speed value into corresponding horse-printing rhythm frequency and display color parameters, and outputs a PWM control signal to the RGB driver module. The RGB driver module drives the light strip to display racing light effects linked to the vehicle speed according to the control signal. When the vehicle speed is within the speed limit range, the light strip displays the first preset color and the horse-printing rhythm frequency increases with the vehicle speed; when the vehicle speed exceeds the speed limit range, the light strip displays the second preset color and increases the horse-printing rhythm frequency to achieve an overspeed warning effect.

[0110] In collision avoidance warning mode, the system uses information from the vehicle's surrounding environment as the trigger source. The main control module acquires information about objects around the vehicle from the vehicle's radar system and 360-degree imaging system via the vehicle communication bus, identifies the direction and distance of approaching objects, generates corresponding warning light effect control parameters for the side light strips, and outputs PWM control signals to the RGB driver module. The RGB driver module then drives the light strip corresponding to the approaching object to display a flashing warning light effect based on the control signal.

[0111] In the vehicle's multimedia audio-synchronized rhythmic mode, the system uses the audio output from the vehicle's multimedia system as the trigger source. When the vehicle's multimedia host plays audio and video content, the audio and video data streams are transmitted to the deserialization module via the GMSL bus. The deserialization module deserializes the serial audio and video data streams, separating the audio stream and transmitting it to the main control module via the I2C bus. The main control module generates lighting drive parameters in real time based on the rhythm and volume characteristics of the audio stream and outputs PWM control signals to the RGB drive module. The RGB drive module drives the light strip to present a rhythmic lighting effect synchronized with the multimedia audio according to the control signal.

[0112] Both the ambient lighting mode and the car infotainment system audio synchronization rhythm mode support manual switching to a static display mode with fixed color and brightness. Users can choose between dynamic rhythm or static constant light display effects according to their needs.

[0113] In some implementations, the controller is also configured to control the operation of the ambient lighting module according to preset rules; and / or The controller is also configured as follows: The ambient lighting mode is configured as the default mode, and when the vehicle system detects that multimedia is being played, the vehicle system's multimedia audio synchronization rhythm mode is used as the basic display mode. When the vehicle is in basic display mode, if an object is detected approaching the vehicle, the collision warning mode is triggered. If no object is detected approaching the vehicle and the vehicle speed exceeds the speed limit, the racing mode is triggered. When the trigger conditions for collision avoidance warning mode or racing mode disappear, control the ambient lighting module to return to the basic display mode.

[0114] Specifically, as mentioned above, the central control display screen 100 of this application embodiment has multiple ambient lighting modes to cope with different usage scenarios. However, when multiple modes meet the trigger conditions simultaneously, if there is a lack of unified scheduling rules, mode concurrency conflicts can easily occur, leading to chaotic lighting displays. In addition, if the system cannot automatically return to the normal entertainment mode after the safety warning ends, manual intervention by the user is required, which not only affects the user experience but may also distract the driver during driving.

[0115] In this embodiment, mode scheduling and switching rules are preset within the controller 30. By setting a default mode and a basic display mode, and clarifying the priority of safety warning modes, the ambient lighting module 10 can automatically and smoothly switch between modes according to the real-time status of the vehicle, and automatically return to the entertainment display state after the safety warning conditions are lifted.

[0116] The controller 30 is configured to control the operation of the ambient light module 10 according to preset rules. The preset rules refer to the logical judgment program that is pre-written and stored in the controller 30 to determine the triggering order, priority and switching conditions of each working mode.

[0117] During operation, the controller 30 is configured with the ambient light pickup mode as the default mode. The default mode refers to the initial working state of the ambient light module 10 when the system starts up and no other specific triggering conditions are detected.

[0118] When multimedia playback is detected from the vehicle's infotainment system, the multimedia audio synchronization rhythm mode will be used as the basic display mode. The basic display mode refers to the primary operating state in which the ambient lighting remains active for extended periods during typical entertainment scenarios.

[0119] When operating in basic display mode, the controller 30 continuously monitors the vehicle's status. If an object is detected approaching the vehicle, a collision avoidance warning mode is triggered. If no object is detected approaching but the vehicle speed exceeds the speed limit, a racing mode is triggered.

[0120] Furthermore, when the triggering conditions for the collision avoidance warning mode or racing mode disappear, the controller 30 controls the ambient lighting module 10 to return to the basic display mode. The disappearance of the triggering conditions means that the specific circumstances that caused the system to enter the warning or racing mode no longer exist; for example, objects around the vehicle move away or the vehicle speed drops to within the speed limit. Returning to the basic display mode also means exiting the current high-priority warning state and transitioning back to the previously executed multimedia rhythm state. Through this switching logic, the controller 30 can automatically switch operating modes by judging and coordinating the signal parameters output by the ambient lighting drive module 40 through its internal program logic.

[0121] In this way, the pre-defined scheduling logic effectively avoids display conflicts caused by concurrent multi-mode operation, ensuring that functions related to driving safety, such as collision avoidance warning and overspeed warning, have higher execution priority. Simultaneously, the system automatically reverts to entertainment mode after the warning status is lifted, requiring no manual user intervention. This balances driving safety alerts with the daily entertainment experience in the cabin, improving the system's automation level and the consistency of human-computer interaction.

[0122] Please see Figure 6The following is a complete example to explain the switching control logic of the ambient light module 10 working modes in the embodiments of this application: The controller 30 controls the switching of the working mode of the ambient light module 10 according to the preset priority scheduling rules. The system defaults to the ambient light pickup mode and automatically triggers and restores between the audio synchronization rhythm mode, racing mode and collision warning mode based on the multimedia playback status of the vehicle, the vehicle speed and the detection results of objects around the vehicle.

[0123] Specifically, after the vehicle infotainment system starts up, the ambient lighting module 10 defaults to the ambient lighting pickup mode, and the controller 30 continuously monitors the multimedia playback status of the vehicle infotainment system. If it detects that the vehicle infotainment system is not playing multimedia, it maintains the ambient lighting pickup mode as the current basic display mode. If it detects that the vehicle infotainment system is playing multimedia, it switches to the vehicle infotainment multimedia audio synchronization rhythm mode as the current basic display mode.

[0124] During operation in the basic display mode, the controller 30 monitors the vehicle's surrounding environment and speed in parallel. Regarding the vehicle's surroundings, the controller 30 determines in real time whether any vehicles or pedestrians are approaching. If a vehicle or pedestrian is detected, a collision warning mode is immediately triggered, and the light strip on the side corresponding to the approaching object displays a warning light effect. When the surrounding vehicles or pedestrians move away and the triggering condition disappears, the collision warning mode automatically exits, and the system returns to the current basic display mode.

[0125] Regarding vehicle speed, the controller 30 continuously monitors whether the current speed exceeds the speed limit. If the speed exceeds the speed limit, a racing mode is triggered, and the control light strip displays an overspeed warning effect. When the vehicle speed returns to the speed limit and the triggering condition disappears, the racing mode automatically exits, and the system returns to the current basic display mode.

[0126] Please see Figure 7 and Figure 8 In some embodiments, the button module 20 is integrated into the inner side of the left and right bezels of the central control display screen 100. The button module 20 includes multiple capacitive touch buttons 21 and a capacitive touch acquisition module 22; and / or Touch methods include single-point touch, multi-point touch and swipe touch. Single-point touch includes single-click touch, double-click touch or long-press touch. Multi-point touch includes combination touch of multiple buttons. Swipe touch includes swiping along the edge of the central control display screen in a preset direction. The capacitive touch acquisition module 22 is configured to acquire the status of capacitive touch buttons, generate messages, and send them to the controller.

[0127] Specifically, in related technologies, physical buttons on external central control displays may have poor dust and water resistance, and dust and liquid can easily accumulate in physical gaps, affecting reliability. Furthermore, physical buttons have fixed functions and limited operation methods, failing to support rich touch gestures such as swiping, making it difficult to meet increasingly diverse interaction needs. On the other hand, placing virtual buttons directly on the screen display area would obscure the displayed content, affecting the user's viewing experience.

[0128] In this embodiment, by integrating the button module 20 into the inner side of the left and right bezels of the central control display screen 100, and using capacitive touch buttons in combination with a variety of touch methods, dustproof, waterproof and multifunctional blind operation interaction can be achieved.

[0129] The button module 20 is integrated into the inner side of the left and right bezels of the central control display screen 100. The inner side of the left and right bezels refers to the internal position of the left and right bezels of the central control display screen. The buttons are hidden inside the bezels, which does not occupy the display area and is easy for fingers to touch.

[0130] The button module 20 includes multiple capacitive touch buttons 21 and a capacitive touch acquisition module 22. The multiple capacitive touch buttons 21 are based on the principle of capacitive sensing. When a human finger approaches or touches the button, the capacitance value is changed to achieve touch operation.

[0131] The capacitive touch acquisition module 22 is an integrated circuit module used to detect changes in the capacitance of capacitive touch buttons and convert them into digital signals. The input terminal of the capacitive touch acquisition module 22 is connected to the sensing electrodes of multiple capacitive touch buttons 21, and the output terminal is connected to the communication interface of the controller.

[0132] Touch control methods include single-point touch, multi-point touch, and swipe touch. Touch control methods refer to the specific gestures used by the user to interact with buttons using their fingers. Single-point touch is an operation performed by a single finger on a single button, including single-click, double-click, and long-press touch. Single-click touch is a short press and quick release of the finger on the button. Double-click touch is two consecutive short presses and releases of the finger on the button. Long-press touch is pressing and holding the finger on the button for a specified period of time.

[0133] Multi-touch refers to the operation of using two or more fingers simultaneously on multiple buttons, including combined touch operations on multiple buttons. Combined touch is an operation method in which multiple buttons are triggered simultaneously or sequentially.

[0134] Slide touch control is the operation of continuously moving a finger on the surface of a button, including swiping along the edge of the central control display screen in a preset direction. The preset direction is a pre-defined finger swiping trajectory, such as from top to bottom or from bottom to top. Swiping is the action of continuously moving the finger while it is pressed against the surface of the button.

[0135] When the user performs any of the above-mentioned touch operations, the capacitive touch acquisition module 22 acquires the status of the capacitive touch button 21, generates a message, and sends it to the controller 30. The status refers to the physical condition of whether the button is currently touched or not. The message is a data packet encapsulated according to a specific communication protocol, containing relevant information about the button trigger. After receiving the message, the controller 30 controls the vehicle system to perform corresponding actions according to the pre-configured function definition.

[0136] Thus, by integrating the capacitive touch button 21 into the inner side of the frame, the problems of poor dust and water resistance and easy wear of external physical buttons are overcome, improving the overall reliability of the system. The hidden design maintains the simplicity of the central control display screen 100's appearance and does not occupy the display area. At the same time, it supports various gesture operations such as single-point touch, multi-point touch, and swipe touch, allowing users to operate blindly according to their personal habits, realizing personalized access to functions, enriching the dimensions of cockpit human-machine interaction and operational efficiency.

[0137] Please see Figure 9 The following is a complete example to explain the functional execution logic of the button module 20 of the central control display screen 100 in this embodiment of the application: The touch function execution process includes four stages: touch button definition, touch type recognition, message generation and transmission, and function execution. The controller 30 responds to the touch message uploaded by the capacitive touch acquisition module 22 according to the user's predefined touch function, and communicates with the vehicle system through the deserialization module to execute the corresponding touch operation.

[0138] Specifically, during the touch button definition phase, users can access the touch button customization settings interface through the vehicle's infotainment system to configure and define vehicle functions corresponding to different touch methods such as single-point touch and swipe touch. The configuration information is transmitted through the infotainment system and stored in the controller 30, forming a mapping relationship between touch methods and vehicle functions. Among them, single-point touch includes single-click, double-click, or long-press touch operations, while swipe touch includes swiping along the edge of the central control display screen in a preset direction. Each touch method can be independently associated with vehicle control functions such as navigation start, music switching, air conditioning adjustment, brightness adjustment, and volume adjustment.

[0139] When a user performs a touch operation on the button area, the capacitive touch acquisition module 22 detects the capacitance change data of each capacitive touch button 21 in real time, identifies the type of the current touch operation as single-point touch or swipe touch, and generates a standard message containing touch type, button position, and operation timing information based on the identification result. Subsequently, the capacitive touch acquisition module 22 transmits the generated message to the controller 30 via the communication bus. After receiving the message and performing verification and parsing, the controller 30 forwards the touch information to the deserialization module via the I2C or SPI communication interface. The deserialization module encapsulates the touch information and establishes communication with the vehicle system via a high-speed serial bus, transmitting the touch command to the vehicle domain controller. Upon receiving the touch command, the vehicle system, based on the pre-stored touch function mapping relationship, calls the corresponding function module to execute the single-point touch defined function or swipe touch defined function, including vehicle control functions such as navigation start, music switching, air conditioning adjustment, brightness adjustment, and volume adjustment, thus fulfilling the user's touch operation request.

[0140] Please see Figure 10 The following is a complete example to explain the appearance, structure and function of the central control display screen 100 of the present application. The front panel of the central control display screen 100 is surrounded by four sets of light strips 11 of the ambient light module 10. The left and right sides of the frame are respectively integrated with multiple sets of capacitive touch buttons 21 of the button module 20. The central area of ​​the central control display screen 100 is the LCD display and touch area.

[0141] Specifically, in this embodiment, four sets of RGB three-color light strips are arranged around the inner side of the four sides of the front panel, while multiple capacitive touch buttons 21 are vertically arranged inside the left and right side frames, thereby constructing an integrated structure with light surround and dual-side touch control. This ensures both the uniformity of light output and the convenience of operation, while maintaining the overall appearance of the central control display screen and the simplicity of the interior design.

[0142] The LCD display and touch area is located in the center of the central control display screen 100, serving as the display area for the vehicle's infotainment system and providing full-screen touch interaction. Four sets of light strips 11 are respectively positioned on the upper, lower, left, and right sides of the frame, extending along the length of the corresponding frame and concealed within a recessed cavity inside the frame. During production and assembly, the RGB tri-color light strips must fit tightly against the frame to ensure uniform light transmission. The ambient light driver module is integrated into the circuit board inside the central control display screen, interacting with the audio processing module and controller. Light is evenly transmitted to the driver and passengers through the frame's light guide structure. In one example, ten capacitive touch buttons 21 are respectively installed inside the left and right side frames, arranged vertically along the frame to form a button column. The sensing electrodes of the buttons are embedded within the frame, with no external protrusions. After assembly, the capacitive touch sensing modules within the left and right side frames are connected to the controller to ensure stable transmission of touch signals. Each LED strip can be independently configured with display parameters and can independently turn on or off the corresponding side's rhythm linkage function, supporting single-side display control. The drive signals of each LED strip are uniformly scheduled and controlled by the controller 30. The specific number of buttons can be adaptively adjusted according to the vehicle configuration requirements, and is not limited to ten.

[0143] All four light strips 11 are electrically connected to the ambient light driver module 40 via internal circuit board wiring, and the controller 30 independently drives and controls each light strip through the ambient light driver module 40. Each capacitive touch button 21 is electrically connected to the capacitive touch acquisition module 22, which generates a message from the acquired touch status and transmits it to the controller 30.

[0144] During operation, the controller 30 can output independent driving parameters to the four sets of light strips 11 according to the current working mode and vehicle status. It can configure the display color, brightness, and dynamic effects for the light strips on the upper, lower, left, and right sides respectively, achieving independent operation and coordinated operation of the lighting effects on each side. When the user performs touch operations, they can perform single-click, double-click, long-press, combination key press, or swipe operations in the corresponding button areas on the left and right sides. The capacitive touch acquisition module 22 detects the capacitance changes of each button in real time, identifies the corresponding touch actions, and generates touch messages that are transmitted to the controller 30. The controller 30 forwards the touch information to the vehicle system, which then executes the pre-configured corresponding functions.

[0145] Please see Figure 11The hardware design architecture of the central control display screen 100 of this application embodiment is explained below with a complete example. The central control display screen 100 includes a power management module, a central control screen connector and a backlight driving module. The MCU main control module (controller) is electrically connected to the ambient light module, button module, audio acquisition component and display component through each functional module, and establishes signal interaction and power supply connection with the vehicle system and vehicle peripherals through the central control screen connector.

[0146] The central control display screen integrates multiple functions such as lighting drive, audio processing, touch capture, and screen display, involving multiple signal links including power transmission, control command transmission, audio and video transmission, and touch data feedback. By setting up a central control screen connector as the unified external interface for the entire unit, and working with a power management module to distribute and stabilize the power supply, the controller, as the core, schedules the various functional modules, constructing a clearly hierarchical and standardized modular circuit system architecture to ensure the stable and coordinated operation of all functions.

[0147] The central control screen connector serves as a unified interface for connecting the central control display screen to external systems. It establishes bidirectional communication connections with the vehicle's infotainment system via CANFD, GMSL, and I2C buses, receiving vehicle status information, control commands, and audio / video data streams from the infotainment system, and transmitting interactive data such as touch button messages back to the infotainment system. Simultaneously, it receives vehicle power input, providing power to the various modules within the central control display screen. Information about the vehicle's surroundings collected by external ultrasonic radar, millimeter-wave radar, and the 360-degree imaging system is integrated and processed by the infotainment system and transmitted to the central control display screen 100 via corresponding buses.

[0148] The input terminal of the power management module is electrically connected to the power supply pin of the central control screen connector, and the output terminal is electrically connected to the MCU main control module, the deserialization module (video display deserialization module) and other functional modules respectively. It is used to perform voltage conversion, filtering and voltage regulation on the input vehicle power supply, provide a matching stable operating voltage for each functional module, suppress power supply noise interference, and ensure the reliable operation of each module.

[0149] The MCU main control module, as the main control core of the system, is connected to the RGB LED driver module (ambient light driver module) through the PWM signal interface, to the audio processing module through the I2S audio interface, to the capacitive touch acquisition module through the I2C communication interface, and to the video display deserialization module through the I2C communication interface, so as to realize the issuance of instructions and data interaction to each functional module.

[0150] The output of the RGB LED driver module is connected to four groups of RGB LED light strips (light strips) on the top, bottom, left, and right sides respectively. It receives the PWM control signal output by the MCU main control module, converts it into a driving current of corresponding amplitude, and independently controls each group of light strips to operate according to preset display parameters.

[0151] The input of the audio processing module is connected to a microphone. After amplifying, filtering and converting the audio signal picked up by the microphone in the cabin, the signal is transmitted to the MCU main control module via the I2S bus to provide audio linkage for the ambient lighting mode.

[0152] The capacitive touch acquisition module is electrically connected to the left and right ten-key capacitive touch strips respectively. It collects the capacitance change status of each capacitive touch button in real time, identifies the corresponding touch action, generates a standard message, and then transmits it to the MCU main control module through the I2C bus.

[0153] The deserialization module connects to the central control screen connector via the GMSL bus, receiving serial audio and video data transmitted from the vehicle's infotainment system and performing deserialization. After deserialization, the video signal is output to the backlight driver module via the LVDS interface. The backlight driver module then drives the LCD touch panel to display the screen and enable full-screen touch interaction. Simultaneously, the deserialization module separates the audio stream from the audio and video data and transmits it to the MCU main control module via the I2C bus, providing audio synchronization for the vehicle's multimedia audio synchronization mode.

[0154] The central control display supports two power supply methods: vehicle host power and vehicle low-voltage battery power. Vehicle power is input to the power management module via the central control screen connector. The power management module outputs multiple stable operating voltages to power all modules of the system. Control commands, vehicle speed information, and vehicle perimeter warning information output by the vehicle system are transmitted to the MCU main control module via the CANFD bus. High-definition audio and video data are transmitted to the deserialization module via the GMSL bus.

[0155] Based on the received signals and user-preset configurations, the MCU main control module sends corresponding lighting effect control commands to the RGB LED driver module, driving each group of RGB LED strips to achieve the corresponding working mode lighting display.

[0156] The MCU main control module receives the cockpit audio signal from the audio processing module or the multimedia audio stream separated by the deserialization module, and controls the RGB LED light strip to move synchronously with the audio rhythm.

[0157] The MCU main control module receives touch messages uploaded by the capacitive touch acquisition module and forwards them to the vehicle system to execute the corresponding vehicle control functions.

[0158] The deserialization module simultaneously transmits the deserialized video signal to the display panel, ensuring real-time display and touch interaction of the vehicle's infotainment system.
