Description

Technical Field

[0001] This application relates to the field of vehicle control systems, specifically to a vehicle steering wheel interactive control system based on interactive indicator points and the vehicle thereof. Background Technology

[0002] With the continuous development of automotive technology, the functions of in-vehicle equipment are becoming increasingly complex, and the steering wheel, as an important connection between the driver and the vehicle, is also constantly evolving. Traditional steering wheel assemblies typically only have basic steering functions and cannot display information or perform control operations. Drivers must view and operate vehicle information through the central control screen or other independent devices, which not only increases the complexity of the operation steps but also causes drivers to frequently shift their gaze, significantly increasing the risk of distraction.

[0003] To address these issues, some vehicle steering wheels have begun to adopt a simple, zone-based interactive design that integrates more functions, such as displaying vehicle information and controlling in-vehicle equipment. However, this design lacks effective visual guidance and operational confirmation mechanisms, posing a risk of accidental touches and potentially leading to unexpected function activation, causing inconvenience to drivers and passengers. Summary of the Invention

[0004] This application provides a vehicle steering wheel interactive control system and vehicle based on interactive indicator points, which can solve the problems of existing vehicle steering wheel control systems having single functions, lacking effective visual guidance and operation confirmation mechanisms, and having the risk of accidental touch.

[0005] In a first aspect, embodiments of this application provide a vehicle steering wheel interactive control system based on interactive indicator points, comprising: a steering wheel body, a finger position detection module, an in-vehicle system controller, and a vehicle display device. Interactive indicator points are provided on the steering wheel body, and a function operation area is provided around the interactive indicator points on the steering wheel body. The finger position detection module is disposed on the surface of the steering wheel body and is used to detect the position information of the point on the function operation area where a finger strikes. The in-vehicle system controller is connected to the finger position detection module and is used to generate a first feedback signal based on the position information. The vehicle display device is connected to the in-vehicle system controller and is used to display corresponding function prompts based on the first feedback signal. When the finger position detection module detects that the point where a finger strikes has been continuously struck for a preset duration, the in-vehicle system controller generates a second feedback signal for function confirmation.

[0006] In one embodiment, the control system further includes: a finger control pointer and a pressure sensor. The finger control pointer is disposed on the surface of the steering wheel body and connected to a finger position detection module. When the driver's hand is detected within the detection range of the finger position detection module, the finger control pointer generates an optical signal pointing to the interactive indicator point. The pressure sensor is disposed inside the interactive indicator point and connected to the vehicle system controller. It is used to detect the pressure value applied by the finger at the interactive indicator point. When the pressure value exceeds a preset threshold, the vehicle system controller generates a third feedback signal containing functional information. The vehicle display device displays all functional prompts based on the third feedback signal.

[0007] In one embodiment, the system further includes: a fingerprint recognition module, which is disposed inside the interactive indicator point and is used to collect fingerprint information generated when the interactive indicator point is first touched by a finger after the vehicle is started, and transmit the fingerprint information to the vehicle system controller for comparison with pre-stored information;

[0008] When the fingerprint information is the same as at least one pre-stored fingerprint information, the vehicle system controller generates a third feedback signal containing functional information; when the fingerprint information is different from all pre-stored fingerprint information, the control system is in a locked state.

[0009] In one implementation, when the fingerprint information is the same as at least one pre-stored fingerprint information and the vehicle is in an unconventional driving state, the vehicle system controller generates a third feedback signal containing functional information after the vehicle returns to a normal driving state. When the fingerprint information is different from all the pre-stored fingerprint information, the vehicle system controller generates a false touch signal. When the false touch signal is generated a preset number of times within a preset time, the control system enters the safety protection mode.

[0010] In one implementation, when the fingerprint information is the same as at least one pre-stored fingerprint information, if it is detected that the finger moves away from the interaction indicator point within a set time, the vehicle system controller generates a false touch signal.

[0011] In one embodiment, the system further includes an operation recording module and an adaptive module. The operation recording module is connected to the vehicle system controller and is used to record the current second feedback signal and update the historical usage data based on the second feedback signal. The adaptive module is connected to the operation recording module and the vehicle display device and is used to adjust the display content of the vehicle display device based on the historical usage data.

[0012] In one implementation, the adaptive module is further configured to sort the usage frequency of each function from high to low based on historical usage data, and adjust the display order of the function list on the vehicle display device according to the usage frequency. The adaptive module is also used to group adjacent functions that are triggered consecutively in the operation sequence into the same function group based on historical usage data; The adaptive module is also used to adjust the display brightness of the vehicle display device according to the light intensity of the driving environment; The adaptive module is also used to adjust the response speed of the vehicle display device according to the driving speed.

[0013] In one embodiment, the control system further includes a voice broadcast module and a fault diagnosis module. The voice broadcast module is connected to the vehicle system controller and is used to generate corresponding voice prompts based on the first feedback signal and the second feedback signal. The fault diagnosis module is connected to the vehicle system controller, the finger position detection module, the vehicle display device, and the voice broadcast module, and is used to detect the working status of each component in the control system and to provide prompts through the voice broadcast module when the working status of a component is abnormal.

[0014] In one embodiment, the finger position detection module is further used to detect the duration of finger stay and movement trajectory in the functional operation area, and the finger position detection module is connected to the voice broadcast module; When the finger position detection module detects that the duration of the finger being hit on the function operation area is within a preset threshold range, and the displacement of the finger movement trajectory generated on the function operation area is less than a preset displacement threshold, the voice broadcast module outputs a prompt signal and the vehicle system controller enters the feedback confirmation mode.

[0015] In one embodiment, the control system further includes a hand posture detection module, which is connected to the vehicle system controller. The hand posture detection module is used to detect whether the driver's hands are in an abnormal gripping state of the steering wheel, and then control the vehicle display device to display warning information through the vehicle system controller. Secondly, embodiments of this application provide a vehicle, which includes: a vehicle steering wheel interactive control system based on interactive indicator points as described in any of the above claims.

[0016] The beneficial effects of the technical solutions provided in this application include: This application provides a vehicle steering wheel interactive control system and vehicle based on interactive indicator points. By setting interactive indicator points on the steering wheel body and configuring a function operation area around it, combined with real-time monitoring of the relative position by a finger position detection module, the vehicle system controller can dynamically generate a first feedback signal based on the finger's position information within the function operation area, driving the vehicle display device to present corresponding function prompts. This overcomes the limitation of traditional steering wheels having only one function. At the same time, the driver does not need to leave the steering wheel or operate the central control screen; they can predict the function intent simply by the relative displacement of their fingers within the function operation area, significantly simplifying the operation process and avoiding the need for traditional physical buttons. The complexity of operation caused by touchscreens significantly improves the intuitiveness and flexibility of operation, and also enhances driving safety. At the same time, the system requires the finger to be held in a specific relative position for a preset time before generating a function confirmation signal (second feedback signal). This mechanism, through stability verification in the time dimension, effectively distinguishes between the driver's active operation intention and accidental touch or brief interference, fundamentally reducing the risk of false triggering. While maintaining the simplicity of the steering wheel structure, this solution allows the driver to perceive the function status through the interactive indicators on the steering wheel itself without shifting their gaze, thereby reducing attentional distraction and providing a more reliable operational basis for safe driving.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] This application provides a vehicle steering wheel interactive control system and vehicle based on interactive indicator points, which can solve the problems of existing vehicle steering wheel control systems having single functions, lacking effective visual guidance and operation confirmation mechanisms, and having the risk of accidental touch.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0021] In a first aspect, embodiments of this application provide a vehicle steering wheel interactive control system based on interactive indicator points, comprising: a steering wheel body, a finger position detection module, an in-vehicle system controller, and a vehicle display device. Interactive indicator points are provided on the steering wheel body, and a function operation area is provided around the interactive indicator points on the steering wheel body. The finger position detection module is disposed on the surface of the steering wheel body and is used to detect the position information of the point on the function operation area where a finger strikes. The in-vehicle system controller is connected to the finger position detection module and is used to generate a first feedback signal based on the position information. The vehicle display device is connected to the in-vehicle system controller and is used to display corresponding function prompts based on the first feedback signal. When the finger position detection module detects that the point where a finger strikes has been continuously struck for a preset duration, the in-vehicle system controller generates a second feedback signal for function confirmation.

[0022] In this application, by setting interactive indicator points on the steering wheel body and surrounding the function operation area, combined with the real-time monitoring of relative positions by a finger position detection module, the vehicle system controller can dynamically generate a first feedback signal based on the finger's position information within the function operation area, driving the vehicle display device to present corresponding function prompts, thus breaking through the limitations of the traditional single function of the steering wheel. Simultaneously, the driver does not need to leave the steering wheel or operate the central control screen; they can anticipate the function intent simply by the relative displacement of their finger within the function operation area, significantly simplifying the operation process, avoiding the operational complexity caused by traditional physical buttons or touchscreens, greatly improving the intuitiveness and flexibility of operation, and enhancing driving safety. Furthermore, the system requires the finger to remain in a specific relative position for a preset duration before generating a function confirmation signal (second feedback signal). This mechanism, verified by time-dimensional stability, effectively distinguishes between the driver's active operation intent and accidental touches or brief interference, fundamentally reducing the risk of false triggering. This allows the driver to perceive the function status through the interactive indicator points on the steering wheel body without shifting their gaze, thereby reducing attentional distraction and providing a more reliable operational basis for safe driving.

[0023] In this application, the interactive indicator can be a small red dot. This red dot employs a highly integrated LED structure, containing a dual-color LED chip array capable of emitting visible light and infrared light signals independently or in combination. The visible light signal primarily provides intuitive visual feedback, indicating system status through different colors and flashing patterns. The infrared light signal is used in conjunction with finger control of the pointer for high-precision position detection, unaffected by ambient lighting conditions. Furthermore, the interactive indicator's surface is covered with a special optical coating that effectively suppresses glare while maintaining high light transmittance, ensuring clear visibility even under strong direct sunlight without causing visual interference to the driver.

[0024] The interactive indicator points are located on the outer edge of the steering wheel body and in a position that the driver's fingers can touch, such as in the area near where the driver's left or right thumbs are naturally placed, ensuring that the driver can easily reach them without adjusting their hand posture when holding the steering wheel normally.

[0025] The finger position detection module consists of an array of miniature capacitive sensors distributed evenly around the edge of the functional operating area. These sensors can detect the finger's contact position, pressure level, and sliding trajectory.

[0026] In this application, the vehicle display device adopts a dual-screen collaborative display architecture, including a central control screen and an instrument panel screen. Both the central control screen and the instrument panel screen use head-up display (HUD) modules, which can display the feedback signals generated by the vehicle system controller within the driver's field of vision. The HUD content undergoes optical optimization processing to ensure high contrast and clarity under various lighting conditions, while avoiding visual confusion with the actual road scene, effectively ensuring driving safety. The HUD module includes optical sealing components to limit the penetration of radiation in the visible light range towards the sensor, preventing the light from the displayed content from interfering with the optical detection system in the steering wheel area. The optical sealing components also have ambient light adaptive adjustment capabilities, dynamically adjusting the transmittance according to the light intensity inside and outside the vehicle, minimizing interference with the optical sensor while ensuring display quality, and ensuring the accuracy and stability of finger position detection.

[0027] The vehicle system controller, as the core of the entire interactive system, connects to the central control screen and instrument panel via wired or wireless communication. It receives and processes optical signals from finger-controlled pointers and generates feedback signals based on the processing results. The feedback signals can include position information, function information, and pressure information.

[0028] Based on the above embodiments, this embodiment enhances the functionality of the aforementioned system by introducing a finger control pointer and a pressure sensor. Specifically, the control system further includes a finger control pointer and a pressure sensor. The finger control pointer is mounted on the surface of the steering wheel body and can employ a miniaturized optical sensor array structure, connected to the finger position detection module. This pointer device possesses high-sensitivity detection capabilities, with a detection range covering a predetermined area around the interactive indicator point. It can capture the approach trajectory and spatial position of the driver's finger: when the driver's hand is detected within the detection range of the finger position detection module, the finger control pointer generates an optical signal pointing towards the interactive indicator point. In other words, when the finger position detection module confirms that the driver's hand has entered the preset detection range, the finger control pointer is immediately activated, emitting a low-intensity directional infrared beam pointing towards the interactive indicator point, forming a visual optical guidance path, effectively reducing blind spots and improving the success rate of the first operation.

[0029] As another key component of this system, the pressure sensor is located inside the interactive indicator point and connected to the vehicle system controller. It is used to detect the pressure value applied by the finger at the interactive indicator point. Furthermore, the surface of the pressure sensor undergoes special treatment to ensure stable sensing performance under various temperature and humidity conditions. Even if the driver is wearing gloves or has wet hands, it can accurately capture pressure change characteristics, greatly expanding the system's applicable scenarios and reliability.

[0030] When the pressure value exceeds a preset threshold, the vehicle system controller generates a third feedback signal containing functional information. The vehicle display device then displays all functional prompts based on this third feedback signal. Unlike the first and second feedback signals, the third feedback signal triggers a full-function display mode, where the vehicle display device presents all available functions in a hierarchical menu format, such as: primary core functions (e.g., navigation, music, telephone) and secondary extended functions (e.g., air conditioning settings, vehicle status viewing).

[0031] This embodiment further integrates a biometric identification security mechanism based on the aforementioned dual-modal detection system. Specifically, the system also includes a fingerprint recognition module, which is located inside the interactive indicator point. After the vehicle is started, the fingerprint information generated when the interactive indicator point is first touched by a finger is collected, and the fingerprint information is transmitted to the vehicle system controller for comparison with pre-stored information.

[0032] The vehicle system controller has a built-in dedicated biometric processing unit responsible for real-time comparison and verification of fingerprint information. The system can pre-store fingerprint templates of multiple authorized drivers. When the fingerprint information matches at least one pre-stored fingerprint, the vehicle system controller generates a third feedback signal containing functional information. This signal not only unlocks basic functions but also loads the specific interface layout, function preferences, and security settings based on the identified driver's identity. When the fingerprint information does not match any of the pre-stored fingerprints, the control system is locked, all interactive functions are temporarily disabled, and a fingerprint mismatch message is displayed to prevent unauthorized operation.

[0033] In this application, the fingerprint recognition module forms a deep collaborative working mechanism with other components of the system. Upon successful authentication, the system not only unlocks the device but also preloads frequently used functions based on the driver's historical data, significantly reducing operation response time.

[0034] The workflow of the intelligent control system is as follows: When the driver's finger first approaches the interactive indicator (the red dot), the finger control pointer immediately activates the near-field sensing mechanism, forming an optical guide path pointing to the red dot. This optical signal not only provides the driver with intuitive operating guidance but also activates the red dot. The red dot's built-in fingerprint recognition module then enters working mode to complete high-quality fingerprint image acquisition.

[0035] The collected fingerprint information is transmitted to the vehicle system controller, which performs identity verification by finding the most likely matching fingerprint template from a pre-stored fingerprint database. If the verification is successful, the system not only enters an active state but also loads the driver's personalized settings (such as frequently used function layouts, interface themes, and security levels). If the verification fails, the system will display a warning light through interactive indicator points, simultaneously providing a voice prompt that the fingerprint has not matched, and enter a security lock state, temporarily disabling all interactive functions and retaining only basic vehicle control functions to effectively prevent unauthorized operation.

[0036] After successful authentication, the system enters the location positioning and intelligent function prompt stage: as the driver's finger continues to approach and touch the function operation area, the finger position detection module captures the precise position, contact area, and movement trajectory of the finger. The vehicle system controller receives and processes this position data in real time, generating the first feedback signal.

[0037] After receiving the first feedback signal, the vehicle display devices (including the central control screen and the instrument panel) project the function prompt information into the driver's natural line of sight through head-up display technology.

[0038] When the finger position detection module continuously monitors the driver's touch behavior in a specific functional area for a preset duration, the system enters the function confirmation and feedback generation phase. The vehicle system controller generates a second feedback signal for function confirmation, which contains complete function instructions and safety confirmation information. After receiving the second feedback signal, the vehicle display devices simultaneously display a function confirmation prompt on the central control screen and instrument panel. At the same time, the voice broadcast module prompts the driver in a preset voice style that the XX function has been confirmed and asks whether to perform the operation, thus achieving multi-sensory interactive confirmation.

[0039] Furthermore, the system features intelligent optimization for special situations: when the fingerprint information matches at least one pre-stored fingerprint and the vehicle is in an unconventional driving state, the onboard system controller generates a third feedback signal containing functional information after the vehicle returns to normal driving. In other words, if fingerprint verification is successful but the driver is in an unconventional driving state such as sudden acceleration or braking, even if an optical signal is detected, the system will automatically delay function execution to prioritize driving safety, and will only proceed with the original instructions after the vehicle has stabilized.

[0040] This system also introduces an operation observation window, serving as a crucial link in the closed-loop logic of scene prediction → feature analysis → action confirmation, effectively distinguishing between genuine operational intentions and unconscious touches. If a finger movement trajectory (such as moving towards a navigation icon) is detected within the observation window, it is immediately determined to have a clear operational intention, activating the function selection interface. Simultaneously, the response speed is adjusted according to the driver's habits (e.g., minimizing the feedback delay for frequent users). If a finger is detected briefly hovering within the observation window without a clear direction of movement, the system will initiate a secondary confirmation mechanism, asking for confirmation via a vibrating red dot or voice prompt, waiting for the driver's clear feedback before executing the command, further reducing the risk of misoperation. Furthermore, the system possesses self-learning capabilities, dynamically adjusting the judgment parameters of each stage based on the driver's long-term usage habits: reducing pressure and displacement threshold sensitivity for users with high operational precision, and extending the observation window time for users with more casual operations, continuously optimizing the human-computer interaction experience.

[0041] Furthermore, to address the issue of false verification caused by unintentional touches by drivers, the system incorporates a multi-dimensional false touch detection and protection mechanism: when a driver's finger touches the red dot, the system not only compares fingerprint information but also simultaneously initiates contact-hold-leave behavior pattern analysis. Specifically, the system sets dual false touch signal trigger conditions: the first is when the fingerprint information does not match any of the pre-stored fingerprint information (i.e., an unauthorized user attempts to operate); the second is when the fingerprint information is different from all pre-stored fingerprint information; even if the fingerprint information matches at least one pre-stored fingerprint information (i.e., an authorized user), the system detects that the finger moves away from the interaction indicator point very quickly after fingerprint acquisition; when the fingerprint information matches at least one pre-stored fingerprint information, the system detects that the finger moves away from the interaction indicator point within a set time. This contact-and-leave behavior pattern conforms to the characteristics of unintentional touches.

[0042] When a false touch is detected, the vehicle system controller generates a false touch signal. When a preset number of false touch signals are generated within a preset time, the control system enters a safety protection mode.

[0043] If the finger is removed immediately after successful verification (without any optical signal), the system determines it as a false touch verification, automatically deletes the operation record (not included in adaptive data statistics), and returns to standby mode within a set time (e.g., 3 seconds). Furthermore, it will not respond to any light touches from the same fingerprint for a period of time (e.g., 30 seconds). If the finger exhibits atypical operating patterns after verification (such as high-frequency shaking or irregular rapid taps), the system will dynamically adjust the verification confidence level based on driving status data such as vehicle speed and steering wheel angle. When the overall risk value exceeds a threshold, the system will automatically lock the function until the status returns to normal.

[0044] In addition, this system also incorporates steering wheel grip posture analysis technology. Specifically, the system also includes a hand posture detection module, which is connected to the vehicle system controller. The hand posture detection module is used to detect whether the driver's hands are in an abnormal steering wheel grip state. When this occurs, the vehicle system controller controls the vehicle display device to display warning information.

[0045] The hand posture detection module monitors the driver's hand position, grip strength distribution, and wrist posture in real time. When the system detects that the driver's hand is in an unnatural grip on the steering wheel (such as abnormal wrist elevation or large area of ​​the palm leaving the grip) and fingerprint verification is triggered, the system will pause the function activation and instead display an icon (e.g., an amber icon) on the instrument panel to warn that the current operation has a safety risk. The verification process will only resume after the driver returns to a normal driving posture.

[0046] When the system detects three consecutive accidental verifications, or when the same fingerprint triggers multiple high-risk operation warnings within a short period, it will automatically enter a safety protection mode. At this time, the fingerprint control function will be temporarily downgraded to basic operation permissions, retaining only core safety functions such as emergency calls and hazard warning lights, until the driver actively restarts the verification process, further strengthening the driving safety defense.

[0047] In addition, the system has the ability to trace and correct accidental touch operations, further improving its anti-accidental touch performance by reviewing historical data. When a suspected accidental touch operation occurs, the system will automatically retrieve the operation log within 3 seconds before and after the trigger, and perform a secondary review by combining multi-dimensional data such as vehicle speed and steering wheel rotation angle, accurately distinguishing between the true intention and the accidental operation, and ensuring the accuracy of the system's judgment.

[0048] Based on the above embodiments, in this embodiment, the system further includes an operation recording module and an adaptive module.

[0049] The operation recording module is connected to the vehicle system controller and is used to record the second feedback signal for this operation, and update the historical usage data based on the second feedback signal. When the system detects that the driver's finger has left the red dot, it records the operation information (such as operation function, duration, etc.) and updates the driver's usage data, and then automatically returns to standby mode, waiting for the next fingerprint verification trigger.

[0050] The adaptive module connects to the operation record module and the vehicle display device, and is used to adjust the display content of the vehicle display device according to historical usage data, and record it in the built-in memory.

[0051] The adaptive module also sorts the frequency of each function from highest to lowest based on historical usage data, and adjusts the display order of the function list on the vehicle's display device according to usage frequency: the system counts the number of times the driver operates different functions and prioritizes frequently used functions in more easily accessible positions. For example, if the driver frequently uses the navigation function, the system will place navigation-related operation options at the top of the function list, reducing the time the driver spends searching for the required function.

[0052] The adaptive module is also used to group adjacent functions triggered consecutively in an operation sequence into the same function group based on historical usage data: when the timing of a driver's operations on certain functions is related, the system will group them together. For example, if a driver often adjusts the volume immediately after playing music, the system may place these two functions in the same group for convenient sequential operation.

[0053] The adaptive module is also used to adjust the display brightness of the vehicle's display device according to the light intensity of the driving environment: in bright light environments (such as direct sunlight at noon), the system will increase the display brightness to avoid screen glare that would prevent the driver from seeing the information clearly; while in dim light environments (such as at night), it will reduce the brightness to prevent strong light from stimulating the driver's eyes and reduce visual fatigue.

[0054] The adaptive module is also used to adjust the response speed of the vehicle's display device according to the driving speed: when the vehicle is traveling at high speed, the system will speed up the function response speed so that the driver's operation can be responded to more quickly and the operation time can be shortened; when traveling at low speed or when parked, the response speed can be appropriately slowed down to balance the accuracy of operation and the consumption of system resources.

[0055] Based on the above embodiments, in this embodiment, the control system further includes a voice broadcast module and a fault diagnosis module.

[0056] The voice broadcast module is connected to the vehicle system controller and is used to generate corresponding voice prompts based on the first and second feedback signals. When the vehicle system controller generates the first feedback signal (function preview) or the second feedback signal (function confirmation), the voice broadcast module immediately retrieves matching content from the pre-stored voice library, processes it through an audio amplifier, and drives the steering wheel's built-in speaker for output. The voice broadcast module also includes a passive filter to improve the sensitivity of the detection.

[0057] The fault diagnosis module is used to detect the working status of various components in the system and prompts the driver for maintenance via a voice broadcast module when a fault occurs. The fault diagnosis module is connected to the vehicle system controller, finger position detection module, vehicle display device, and voice broadcast module. It detects the working status of various components in the control system and provides prompts via the voice broadcast module when a component's working status is abnormal. In this embodiment, the fault diagnosis adopts a hierarchical detection strategy: Level 1 detection is executed every 100 milliseconds to check the basic working status of each component; Level 2 detection is executed every 5 seconds for more in-depth functional testing; Level 3 detection is automatically executed after the vehicle is turned off for a comprehensive system self-check. When the fault diagnosis module detects an abnormal state, the voice broadcast module generates corresponding prompts based on the fault level. Furthermore, the fault diagnosis module is also linked with other vehicle systems (such as the instrument panel and central control screen). Simultaneously with the voice prompts, relevant indicator lights illuminate or display fault information, providing multi-channel fault prompts.

[0058] Based on the above embodiments, in this embodiment, the finger position detection module is also used to detect the duration of finger stay and movement trajectory in the functional operation area, and the finger position detection module is connected to the voice broadcast module; When the finger position detection module detects that the duration of a finger tap on the function operation area is within a preset threshold range, and the displacement of the finger movement trajectory on the function operation area is less than a preset displacement threshold, the voice broadcast module outputs a prompt signal, and the vehicle system controller enters the feedback confirmation mode. If a finger is detected briefly in the observation window without a clear direction of movement, the system will initiate a secondary confirmation mechanism, asking for confirmation of the operation through a small red dot vibration or voice prompt, and waiting for the driver's clear feedback before executing the command, further reducing the risk of misoperation.

[0059] During daily driving, factors such as gloves and sweat may affect the accuracy of fingerprint recognition. To address this, the system incorporates a material recognition algorithm. When it detects special media such as fabric (e.g., gloves) or water stains on the finger surface, it automatically switches to an enhanced recognition mode. Through multi-band signal penetration detection, combined with the comprehensive changes in pressure and displacement, it accurately distinguishes between valid operations and media interference, avoiding misjudgments or missed judgments caused by external factors.

[0060] In extreme environments: Faced with fingerprint recognition interference from strong light or operational deviations caused by finger stiffness in low temperatures, the Little Red Dot intelligent control system automatically activates environmental compensation algorithms. By enhancing sensor sensitivity and optimizing the comparison model, it maintains stable recognition performance, ensuring accurate judgment of user intent under various conditions. In special environments such as rain and snow, the system also dynamically adjusts the operating parameters of the fingerprint recognition module based on environmental sensor data. For example, when rainwater is detected, the sensor enhances the surface sensing signal and combines humidity data to eliminate interference from accidental touches by water droplets. In low-temperature environments, in addition to improving sensor sensitivity, it also optimizes the error tolerance of the comparison algorithm to prevent recognition obstacles caused by changes in finger skin texture, comprehensively ensuring the reliability and stability of the system in complex scenarios.

[0061] This closed-loop logic of scenario prediction → feature analysis → action confirmation improves the accuracy of accidental touch recognition, while controlling the response delay of actual operation to a very short time (e.g., 0.5 seconds), ensuring driving safety without affecting operational efficiency.

[0062] The Little Red Dot system's own operating logic is further integrated with the perception, decision-making, and execution processes of intelligent connected vehicles to form a closed loop, highlighting the Little Red Dot's core role and logical coherence throughout the entire process.

[0063] The control system is configured with a three-tier architecture and the following working logic: Perception Layer: Data Acquisition Centered on the Red Dot: The red dot serves as the core perception node of the system, integrating pressure sensors, optical sensors, and fingerprint recognition modules to form a multimodal data acquisition system. The pressure sensor recognizes different operation methods such as light touch, short press, and long press. Simultaneously, the system acquires real-time vehicle operating status data via the CAN bus, including steering wheel grip status (determined by a steering wheel grip force sensor to control one-handed / two-handed grip), traffic light status, ACC adaptive cruise control status, vehicle speed, steering angle, and other key information. The data fusion processing unit employs a weighted algorithm to perform real-time analysis and correlation of multi-source data from the red dot sensor and the vehicle system. For example, when a light touch + two-handed grip + green traffic light is detected, the system outputs a low-needs-of-operation state; when a long press + one-handed grip + ACC adaptive cruise control is activated, the system outputs a high-needs-of-operation state. This multi-dimensional data fusion mechanism significantly improves the system's accuracy in recognizing driver intentions and avoids misjudgments caused by data from a single sensor.

[0064] Decision-making layer: Intelligent decision-making based on the operation characteristics of the red dot: The decision-making layer constructs a multi-level decision tree model based on the operation characteristics collected by the red dot and vehicle status data. The system first classifies operation commands, classifying entertainment functions such as adjusting volume and changing songs as non-emergency commands, and safety-related functions such as emergency calls and activating hazard lights as emergency commands. Then, it makes a comprehensive judgment based on the operation necessity assessment results: When the red dot receives a non-emergency command such as adjusting volume and the system assesses it as low operation necessity, the decision engine marks the command as postponed and enters a short waiting period, during which the vehicle status changes are continuously monitored; if the vehicle status changes to a safer condition during this period, the command is executed immediately; if the red dot triggers an emergency rescue command (which requires both fingerprint verification and long press operation), regardless of the current vehicle status, the system immediately enters a high operation necessity state, prioritizes the response, and executes directly, skipping all waiting steps.

[0065] The decision-making layer also incorporates driving scenario awareness algorithms, capable of identifying high-risk driving scenarios such as sharp turns and emergency braking. Even if an operational command is detected, it will automatically delay execution to ensure driving safety. Furthermore, the system continuously optimizes decision thresholds through machine learning, dynamically adjusting necessity assessment criteria based on each driver's operating habits to achieve truly personalized intelligent decision-making.

[0066] Execution Layer: The red dot feedback forms a complete closed loop: The execution layer is responsible for transforming decision results into intuitive feedback signals and working in conjunction with other vehicle systems to form a complete touch-judgment-feedback closed loop. When the decision is to postpone, the red dot activates a gentle, slow-flashing mode, using rhythmic flashing of LEDs to convey to the driver that the instruction has been received but will not be executed immediately, avoiding the interference of needing to look away from the central control screen in traditional systems; simultaneously, the system temporarily stores the instruction in a buffer zone, automatically executing it when the vehicle enters a safer state. When the decision is to prioritize response, the red dot immediately switches to a constant red light state, providing clear visual feedback and establishing a direct communication link with relevant systems through the in-vehicle network: for example, when an emergency rescue is triggered, the red dot system immediately activates the in-vehicle communication module, automatically sending a distress signal containing vehicle location and status information, while simultaneously controlling the instrument panel to display emergency operation guidelines. To ensure the reliability of the feedback, the system also features a multimodal feedback mechanism, superimposing tactile feedback (slight vibration of the red dot) or auditory feedback (brief voice prompts) as needed, based on visual feedback, to create a comprehensive interactive experience. The entire execution process strictly adheres to the principle of safety first. All non-emergency operations are only performed after the system confirms that the current driving environment is safe, truly realizing the intelligent interaction concept that operation does not interfere with driving and feedback does not distract attention.

[0067] In summary, this application simplifies the driver's operation process, reduces reliance on the central control screen or other devices, lowers operational complexity, and improves driving efficiency by designing interactive indicator points on the vehicle's multi-function steering wheel and implementing pointer display and function selection. The design of the interactive indicator points allows drivers to flexibly select and confirm functions according to actual needs, realizing customizable and personalized settings of functions and meeting the personalized needs of different users. By selecting the corresponding APP on the screen via remote control and confirming with voice prompts, the problem of accidental touches caused by traditional steering wheel switches or touch switches is avoided, improving the accuracy and reliability of operation and enhancing driving safety. The design of this application eliminates the need for additional physical buttons or touchscreens on the steering wheel itself, reducing the complexity of the physical structure and enabling the driver to operate the steering wheel promptly in emergency situations, thereby improving driving safety. The system receives signals from interactive indicator points through the vehicle system controller and feeds them back to the central control screen and instrument panel, realizing multi-functional integrated display, improving the integration and visualization of vehicle information, and providing drivers with a more comprehensive and convenient vehicle control experience.
