[0002] With the rapid development of the automotive industry and the continuous improvement of its intelligent capabilities, automobiles have become an indispensable means of transportation for people's daily travel. During modern driving, various warning lights are typically displayed on the car's dashboard to alert the driver to abnormal vehicle conditions or potential problems.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.
[0023] Please see Figure 1 , Figure 1 This is a schematic diagram of a warning system based on an automotive instrument panel warning light, provided as an embodiment of this application. Figure 1 As shown, the prompting system provided in this application embodiment includes: a data processing module 10, a first communication module 20, and an information display module 30 connected in sequence; the data processing module 10 is used to monitor the working status of the warning lights on the car dashboard, determine the fault alarm information corresponding to the fault warning light according to the warning light in the fault state, and send the fault alarm information to the information display module 30 through the first communication module 20; wherein, the fault alarm information includes at least one of the following: warning light meaning information, fault handling plan, and precaution information; the information display module 30 is used to display the fault alarm information.
[0024] Here, the data processing module 10 is typically installed in the automotive instrument system to realize real-time perception, data acquisition, and analysis of the working status of the instrument panel warning lights. For example, the hardware of the data processing module 10 may include components such as a microprocessor, a signal acquisition interface, and a storage chip, while the software may include program code such as status monitoring algorithms and alarm information matching logic.
[0025] On the one hand, the data processing module 10 needs to establish a connection with the alarm light control circuit of the instrument panel to receive the alarm light's working status signal in real time; on the other hand, the data processing module 10 needs to analyze the collected working status signal to determine whether the alarm light is in a fault state. For example, when the alarm light is lit, it indicates that the alarm light is in a fault state.
[0026] Optionally, the data processing module 10 monitors the operating status of the warning lights on the vehicle's dashboard. Through a preset signal acquisition and detection mechanism, it continuously acquires the operating status of all warning lights on the dashboard, such as the engine malfunction indicator light, brake system warning light, oil pressure warning light, and tire pressure warning light. The data processing module 10 features real-time performance, continuity, and accuracy during monitoring. Real-time performance requires the data processing module 10 to capture status changes within milliseconds after the warning light illuminates, avoiding delayed fault indications. Continuity requires the data processing module 10 to continuously monitor during vehicle ignition without interruption. Accuracy requires the data processing module 10 to accurately distinguish between normal illumination of the warning lights, such as brief illumination during self-test, and fault illumination, such as continuous illumination caused by an actual fault, avoiding misjudgments.
[0027] In an optional implementation, the data processing module can sample the operating status signal of each warning light according to a preset cycle, compare the currently sampled operating status signal with the operating status signal of the previous cycle, and combine this with the vehicle's operating status, such as whether it is in the self-test phase or whether it has started successfully, to determine whether the illumination of the warning light indicates a fault. For example, when the vehicle starts, it enters the self-test phase, during which the engine malfunction indicator lamp, brake system warning light, etc., will illuminate briefly, usually for 2-3 seconds. The data processing module identifies the self-test phase by acquiring the vehicle's starting status signals, such as the ignition switch signal and engine speed signal. Even if the warning light illumination signal is sampled during this phase, it will not be determined as a fault. After the self-test is completed, if the engine malfunction indicator lamp remains illuminated, the data processing module determines that the warning light is in a fault state.
[0028] Among them, a fault warning light refers to a warning light that remains illuminated during normal vehicle operation, indicating an abnormality or malfunction in a specific system or component of the vehicle. Different types of warning lights correspond to different vehicle systems or components.
[0029] Specifically, the data processing module determines the fault alarm information corresponding to the fault alarm light through the following steps: based on the alarm light in the fault state, it searches for the fault alarm information corresponding to the fault alarm light in the pre-established alarm light information database. The alarm light information database includes all alarm light information and the fault alarm information corresponding to each fault alarm light.
[0030] The above process requires establishing a precise mapping relationship between the fault warning light and the fault alarm information to ensure that the extracted information is accurate, comprehensive, and meets the driver's information needs.
[0031] Here, a warning light information database is pre-established, storing warning light information and a one-to-one correspondence between each warning light and its associated information. This database covers relevant information for all warning lights in the vehicle model and supports future updates via the vehicle's network.
[0032] Specifically, the unique identifier of the alarm light in a faulty state is used as the search keyword to retrieve the corresponding fault alarm information through association query in the alarm light information database. This process is efficient and accurate, ensuring that the search is completed and the results are returned in a short time.
[0033] For example, the data processing module integrates a mapping table between alarm lights and fault alarm information. The mapping table contains a unique identifier for each alarm light, such as its number and name, as well as the corresponding fault alarm information, such as the meaning of the alarm light, fault handling solutions, and precautions. The data processing module can quickly locate and extract the corresponding fault alarm information by searching the mapping table using the unique identifier of the fault alarm light.
[0034] The fault alarm information refers to the set of information corresponding to the warning light indicating a fault, used to convey fault-related content to the driver. This information helps the driver quickly understand the meaning of the warning light, master the correct troubleshooting methods, and understand relevant precautions. Specifically, the fault alarm information includes at least one of the following: warning light meaning information, troubleshooting methods, and precautions information. Here, the warning light meaning information explains the specific fault type and possible causes represented by the illuminated warning light; the troubleshooting methods provide actionable steps to guide the driver on how to troubleshoot or handle the fault; and the precautions information reminds the driver of actions to avoid during troubleshooting or before the fault is resolved, as well as potential safety risks.
[0035] In an optional implementation, fault alarm information can be stored in a structured data format, such as JSON, to ensure that the language is concise and clear, avoiding excessive use of technical terms. At the same time, key information, such as "stop immediately" and "no high-speed driving," can be bolded or specially marked to facilitate drivers to quickly grasp the key points.
[0036] For example, when the data processing module determines that the engine malfunction warning light is in a faulty state, it can retrieve the corresponding fault alarm information by searching the mapping table using the unique identifier of the warning light, such as engine-001. The warning light's meaning is: the engine oil pressure is too low, which may lead to insufficient engine lubrication and accelerated wear of internal parts. The troubleshooting solution is: immediately reduce vehicle speed, find a safe area to park, turn off the engine, wait 5-10 minutes, and then check the engine oil level. If the level is too low, add the correct type of engine oil to the standard level. After adding the oil, start the engine. If the warning light is still on, contact a mechanic. The precaution is: do not drive at high speed or for extended periods while the warning light is on to avoid serious engine damage.
[0037] Furthermore, the data processing module 10 sends the fault alarm information to the information display module 30 via the first communication module 20. Here, the first communication module 20 refers to the data transmission channel between the data processing module 10 and the information display module 30, used to achieve efficient and stable transmission of fault alarm information from the data processing module 10 to the information display module 30. Optionally, the first communication module 20 may include a communication module based on an in-vehicle bus, such as a CAN bus or LIN bus, or a cross-system communication module based on a dedicated communication protocol, such as the SOME / IP protocol, to adapt to the complex electromagnetic environment inside the vehicle and possess characteristics such as strong anti-interference capability, low transmission delay, and reliable data transmission. For example, the data processing module 10 and the information display module 30, such as the central control screen display module, are connected via a CAN bus. The CAN controller of the first communication module 20 encapsulates the fault alarm information according to the CAN protocol format, and then sends the encapsulated data packet to the CAN bus through the CAN transceiver. After the CAN receiver of the information display module 30 receives the data packet, it extracts the fault alarm information through the parsing program of the first communication module 20.
[0038] The first communication module 20 transmits the fault alarm information extracted by the data processing module 10 to the information display module 30 according to a preset transmission mechanism and data format. In an optional embodiment, after the data processing module 10 determines the fault alarm information and transmits it to the first communication module 20, the first communication module 20 immediately starts the transmission process without waiting for periodic trigger signals, and at the same time, a data verification mechanism is used during the transmission process to ensure data integrity.
[0039] Furthermore, the information display module 30 is used to display fault alarm information. Here, the information display module 30 refers to a combination of hardware devices and software programs that possess information receiving, processing, and visualization display functions, capable of presenting fault alarm information in a form easily perceived by the driver, such as text, images, and icons. It serves as the direct interactive terminal for the driver to obtain fault alarm information. Here, the information display module 30 must have good visual readability; the displayed content must be clear and concise, and easily identifiable by the driver under different lighting conditions. Examples of common information display modules 30 include, but are not limited to, automotive central control screen display modules, HUD projection modules, and AR glasses linkage modules, which are described below as examples: In the first scenario, the information display module includes a central control screen display module, on which a customized application is installed. The central control screen display module is used to display the fault alarm information in the form of a pop-up window after the customized application, which is in operation, receives the fault alarm information sent by the data processing module.
[0040] The central control screen display module refers to the hardware device in the vehicle's central control system responsible for information display and user interaction. It typically consists of a display screen, display driver circuitry, and touch sensing module, serving as the runtime environment for customized applications and the terminal for displaying fault information. The central control screen display module boasts high compatibility and stability, adapting to different versions of customized applications and maintaining normal operation in the complex operating environment of a vehicle. Simultaneously, the display screen offers excellent visual effects, such as high resolution, high brightness, and wide viewing angles, ensuring clear visibility for the driver under varying lighting conditions. For example, the central control screen display module can utilize an IPS touchscreen display with automatically adjustable brightness based on ambient light intensity. It supports multi-layered display, such as simultaneously displaying navigation, music, and fault pop-ups, and supports single-point touch and gesture operations.
[0041] Here, a customized application refers to an application specifically developed for receiving and displaying fault alarm information. Installed in the operating system of the central control screen display module, it possesses functions such as data reception, information parsing, display control, and user interaction. Customized applications should be lightweight to avoid consuming excessive central control system resources, while also having the ability to start automatically and run in the background to ensure immediate operation after the car is started and to receive fault alarm information at any time.
[0042] In an optional implementation, the customized application can be developed in C++, with an interface built on the Qt framework. It supports communication protocols with the first communication module, such as the CAN bus protocol and the SOME / IP protocol. Upon startup, the customized application automatically establishes a data connection with the first communication module and enters a background monitoring state. When it receives a fault alarm message from the data processing module, the customized application immediately parses the data, extracts the various fields of the fault alarm message, and generates a pop-up display command according to preset display rules.
[0043] Alternatively, if users require more in-depth assistance, they can directly call the car manufacturer's service hotline or navigate to the nearest repair shop through the customized application.
[0044] Furthermore, the central control screen display module displays fault alarm information in the form of pop-up windows. Specifically, the central control screen display module pops up an independent prompt window above the current display interface, such as navigation, music, or settings, to display fault alarm information. The pop-up window can have a semi-transparent background, a fixed size, and clearly defined close and interaction buttons. This is a key display method for achieving real-time transmission of fault information without interfering with the original functions of the central control screen. For example, the pop-up window can be designed as a rectangular window, with a size of 60% of the width and 40% of the height of the central control screen, fixedly displayed in the center of the upper half of the central control screen, with a black semi-transparent background (e.g., 60% transparency), and a border of different colors, such as red for emergency faults or yellow for general faults. For example, the fault alarm information in the pop-up window can be displayed in the form of text descriptions, image examples, or video tutorials.
[0045] Then, the central control screen display module receives the fault alarm information sent by the first communication module, and displays the fault alarm information in the form of a pop-up window in the central area of the screen through a customized application. The background of the pop-up window can be semi-transparent to avoid completely obscuring the original navigation, music and other interface content of the central control screen. At the same time, the text in the pop-up window can be bold and black, and the font size can be distinguished according to the importance of the information to ensure that the driver can quickly capture the key information.
[0046] In the second scenario, the information display module includes a HUD projection module. The HUD projection module is used to receive fault alarm information and display key alarm information from the fault alarm information on the windshield. Key alarm information refers to alarm information characterized in the form of keywords.
[0047] Here, the HUD projection module refers to a hardware unit with image generation and projection functions, including an image processor, a laser projection component, and a focus adjustment circuit. It can convert critical alarm information into a clear projected image and project it onto the HUD display area of the windshield. For example, the HUD projection module can use DLP (Digital Light Processing) projection technology with an image resolution of 800×480. The projection brightness can be automatically adjusted according to the ambient light intensity, and the focus adjustment circuit can automatically adjust the projection focus according to the driver's posture to ensure image clarity, keeping the projected image on the windshield clear and free from blurring or distortion. Specifically, key alarm information refers to keywords or short phrases extracted from fault alarm information that can summarize the core content of the fault, such as abnormal braking - slow down and stop, battery fault - avoid high speed. Its function is to allow the driver to quickly obtain the core fault information within the limited projection area of the HUD.
[0048] In one optional implementation, the HUD projection module incorporates a keyword extraction algorithm to generate key alarm information by identifying the subject and core action in the fault alarm message. For example, if the fault alarm message means that the power battery power management system is malfunctioning, which may lead to decreased charging efficiency or shortened driving range, the keyword extraction algorithm extracts the subject: power battery, and the core action: malfunction. Combining this with the core suggestion in the handling solution: avoid high speed, the key alarm message is generated as: power battery malfunction - avoid high speed. The above method utilizes a HUD projection module, which can project fault alarm information directly into the driver's line of sight, reducing the need for eye movement and improving safety.
[0049] In the third scenario, the information display module includes an AR glasses linkage module; the AR glasses linkage module is used to receive fault alarm information and display the fault alarm information within the driver's field of vision.
[0050] The AR glasses linkage module refers to the intermediate communication and data processing unit connecting the vehicle's data processing module and the AR glasses device. It integrates communication interfaces, data parsing circuits, and AR data conversion chips to receive fault alarm information and convert it into a format recognizable by the AR glasses, enabling collaborative operation between the vehicle system and the AR glasses. Specifically, the AR glasses linkage module should feature low latency and high compatibility. Low latency prevents delayed display of fault alarm information, while high compatibility requires support for the communication protocols of mainstream AR glasses models on the market, and compatibility with the vehicle system's CAN bus, Ethernet, and other transmission interfaces.
[0051] In an optional implementation, the AR glasses linkage module can adopt a dual communication interface and protocol conversion design. The hardware integrates a CAN bus interface and a Bluetooth interface, while the software includes built-in parsing and conversion programs for the CAN and Bluetooth protocols. For example, when the data processing module sends a fault alarm message via the CAN bus, the CAN interface of the AR glasses linkage module receives the data and uses the built-in protocol conversion program to parse the CAN data packet into a common JSON format. If the AR glasses support Bluetooth communication, the module then sends the JSON format data to the AR glasses via the Bluetooth interface. The entire receiving and format conversion process is kept to a short time to ensure efficient data transmission. Furthermore, AR glasses can render and overlay fault alarm information in the driver's real field of vision based on the display parameters in the AR interactive data, achieving a display effect that integrates information with the scene. This display process must ensure that the AR information is spatially aligned with the real scene to avoid the AR information floating or misaligning due to positioning deviations. At the same time, it must automatically adjust the brightness and contrast of the AR information according to the ambient light intensity to ensure clear display under different lighting conditions.
[0052] The driver's field of vision area refers to the range of AR information display set by the AR glasses device according to ergonomics and driving safety requirements. It is usually the non-core road condition area in front of the driver's field of vision, such as the lower center of the field of vision and the left and right sides. This area is convenient for the driver to quickly obtain information without obstructing key road condition elements such as the road ahead and traffic lights, so as to balance information acquisition and driving safety.
[0053] The above methods provide an immersive experience, make fault alarm information more intuitive, and do not interfere with the driver's attention to road conditions.
[0054] like Figure 2 As shown, the prompting system provided in this application embodiment also includes an instrument panel display module 40; the instrument panel display module 40 is used to receive fault alarm information and display the fault alarm information on the instrument panel.
[0055] The instrument panel display module 40 refers to the hardware unit and software program combination integrated inside the vehicle's instrument panel, possessing information receiving, processing, and display functions. The hardware includes an instrument panel display screen, a display driver chip, and a communication interface; the software includes a data parsing program and display control logic. The instrument panel display module 40 is used to receive and display fault alarm information, realizing a close-range correlation display between the warning lights and fault alarm information. Here, the instrument panel display module 40 meets the requirements of low power consumption and high reliability, adapting to the environment of long-term vehicle operation.
[0056] Here, the instrument panel display module 40 obtains complete fault alarm information from the data processing module 10 and displays the fault alarm information on the instrument panel. Optionally, the fault alarm information can be displayed in a preset display area of the instrument panel. Specifically, a fixed area is pre-defined on the instrument panel display screen specifically for displaying fault alarm information, usually located near the warning light, occupying 15%-20% of the total area of the instrument panel display screen. This avoids obscuring core driving information such as vehicle speed and engine speed, while simultaneously establishing a visual association between the warning light and the fault alarm information, ensuring that the driver can see the fault alarm information without significantly shifting their gaze while observing the warning light, thus improving driving safety.
[0057] The above method eliminates the need for a central control screen or other external devices, simplifying the system architecture. Fault alarm information is located close to the warning light, making it easy for the driver to quickly associate them.
[0058] In one optional embodiment, the prompting system provided in this application further includes: a speech synthesis module and a speech playback module connected to each other, wherein the speech synthesis module is connected to the data processing module; the speech synthesis module is used to receive fault alarm information sent by the data processing module, generate speech prompt information based on the fault alarm information, and send the speech prompt information to the speech playback module; the speech playback module is used to play the received speech prompt information.
[0059] The speech synthesis module refers to a hardware unit with text-to-speech functionality. It has a built-in speech synthesis algorithm and voice library, capable of converting the text content of fault alarm information into a speech signal. The voice playback module refers to a hardware unit that connects the speech synthesis module to the vehicle's audio system. It is responsible for amplifying the speech signal generated by the speech synthesis module and transmitting it to the audio system to enable voice playback.
[0060] For example, when a fault alarm message of "battery fault light" is received, the corresponding text content is: "Power battery power management system is abnormal. Please avoid high-speed driving and go to a repair shop for inspection as soon as possible." The TTS chip can call the built-in speech synthesis algorithm to convert the text into a Chinese speech signal with a normal tone of 120 words per minute, which can ensure clear sound quality. For example, when the car audio system is playing music, after the voice playback module receives the voice prompt message "Engine cooling system water temperature is too high", the signal switching circuit immediately cuts off the music signal, and the audio amplifier amplifies the voice signal and transmits it to the audio system to play the voice message: "Attention, engine cooling system water temperature is too high. Please stop immediately and check the coolant level. Do not continue driving." After the playback is complete, the music playback will automatically resume. The aforementioned voice playback method does not require occupying central control screen resources, making it suitable for scenarios where drivers need to focus on road conditions while driving, and it has a low implementation cost.
[0061] The embodiments of this application can select the most suitable solution based on actual needs and target user groups. For example, for high-end models, HUD or AR glasses prompts can be considered; for economy models, voice prompts or dashboard-integrated prompts can be considered.
[0062] In one optional embodiment, the prompting system provided in this application further includes: a second communication module, which is connected to a data processing module; the data processing module is used to send fault alarm information to a smart terminal through the second communication module, so that the smart terminal displays the fault alarm information and an extended processing scheme generated based on the fault alarm information.
[0063] Here, the second communication module is independent of the first communication module and is a dedicated hardware module for establishing wireless communication with smart terminals. It includes wireless communication chips such as Bluetooth chips, Wi-Fi chips, antennas, and data conversion circuits to enable data interaction between the vehicle system and the smart terminal. Specifically, the second communication module can have low power consumption characteristics, entering sleep mode after the vehicle is turned off, retaining only the Bluetooth wake-up function. It can also have a device authentication mechanism, connecting only to authorized smart terminals to ensure data security.
[0064] For example, the smart terminal can be a mobile phone, on which a dedicated app can be installed to receive fault alarm information and display the corresponding handling solution on the phone screen; in addition, the dedicated app can also provide extended functions, such as navigating to the nearest repair shop and dialing the service hotline.
[0065] For example, the data processing module can transmit fault alarm information to the second communication module through a preset internal communication interface, such as UART or SPI. Optionally, the data processing module can compress the fault alarm information before transmission, reducing the data volume by 30% to improve transmission efficiency.
[0066] For example, the second communication module can adopt a dual-mode design of Bluetooth and Wi-Fi. For instance, when the data processing module generates a fault alarm message of "engine failure", it sends the fault alarm message to the second communication module through the UART interface. After receiving the message, the second communication module temporarily stores it in the buffer area, and then selects Bluetooth or Wi-Fi transmission according to the connection status of the smart terminal. The entire receiving process takes a short time and can ensure timely information transmission. The above methods can utilize existing smartphone devices without requiring additional hardware investment. They also offer more interactive features, such as sharing fault alarm information with family, friends, or professionals.
[0067] This application embodiment uses a data processing module to acquire the status of warning lights on the car's dashboard in real time and accurately determine the corresponding fault alarm information. A first communication module enables efficient cross-module data transmission, and finally, an information display module presents the fault alarm information intuitively to the driver. This solves the problems of time-consuming and laborious processes, inaccurate information, and poor user experience in existing technologies where drivers need to obtain solutions for warning light malfunctions. Drivers can quickly obtain accurate solutions without consulting manuals or searching the internet, improving the user experience. Accurate and timely fault alarm prompts help drivers take corrective action quickly, avoiding safety risks caused by misoperation. Through cross-system collaboration, the linkage between the car's instrument panel and central control system is achieved, improving the overall vehicle intelligence level. If users can resolve problems themselves, it also reduces the frequency of calling service hotlines or visiting repair shops, lowering service costs for car manufacturers and contributing to improved safety and economy.
