Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a control method and device for a vehicle light shield, a vehicle and a storage medium. Background Art

[0002] In recent years, active safety measures for automobiles have become increasingly powerful and perfect. The so-called active safety measures for automobiles refer to a series of technologies and systems that can take active measures to prevent or avoid traffic accidents. These technologies can monitor the driving status and surrounding environment of the vehicle in real time, remind the driver of potential dangers in time, and take corresponding measures to avoid accidents. The following are some common active safety measures for automobiles: lane departure warning (LDW), automatic emergency braking (AEB), blind spot monitoring (BSM), driver monitoring (DMS), etc. The application of these active safety measures has greatly improved the safety of automobile driving and enabled drivers to drive more safely. With the continuous development of science and technology, active safety technology for automobiles will also be continuously upgraded and improved to provide more reliable protection for people's travel. These active safety systems have gradually become standard means of automobile driving safety, and are also becoming an important factor that people need to consider when choosing a car.

[0003] When driving, sunlight enters the cab through the car windows, causing discomfort to the driver's eyes, thus affecting driving safety and even causing traffic accidents.

[0004] In the related art, shading is performed by manually adjusting the sun visor or by using sunshade glass. However, manually adjusting the sun visor may cause the driver to be distracted during driving and affect driving safety. When using photochromic glass for shading, the glass automatically changes color according to the intensity of sunlight to play a shading role. It simply relies on the intensity of sunlight to change color and cannot be flexibly adjusted. In addition, dark glass can easily cause visual fatigue to the driver, affecting driving safety.

[0043] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0044] The following describes the control method, device, vehicle and storage medium of the vehicle light shield of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the manual adjustment of the sun visor can easily distract the driver and cause safety accidents, the present application provides a control method for the vehicle light shield. In this method, by obtaining the current light intensity and the driver's facial image, and determining the driver's squinting time based on the facial image, when the squinting time is greater than a preset time threshold and the current light intensity is greater than the preset light threshold, the vehicle light shield is controlled to perform a sunshade action. The present application monitors the driver's status through a driver monitoring system, and then uses data such as the on-board light and rain sensors to determine whether the driver is exposed to strong light, and automatically lowers the light shield for the driver. In this way, the problem that the manual adjustment of the sun visor can easily distract the driver and cause safety accidents is solved, and the driver's hands can be freed to improve driving safety.

[0045] Before introducing the control method of the vehicle light shield according to the embodiment of the present application, the control system architecture of the vehicle light shield is introduced.

[0046] 1. DMS module (Driver Monitoring System).

[0047] Hardware composition: The core of the DMS module is a high-definition camera, preferably a model with infrared night vision function, to ensure that the driver's facial image can be clearly captured under various lighting conditions. The camera installation position needs to be carefully designed, usually located above the steering wheel or in the center of the dashboard to maximize the field of view for capturing the driver's facial expressions.

[0048] Algorithm optimization: The convolutional neural network (CNN) algorithm in deep learning is used to process the images collected by the camera in real time. The algorithm first performs face detection and then focuses on the eye area. By analyzing the relative position and movement trajectory of the pupil and eyelid, it can accurately determine whether the driver squints due to strong light. In addition, the algorithm must also be able to distinguish between normal blinking and abnormal squinting caused by strong light to improve the accuracy of judgment.

[0049] Privacy protection: The system must be designed to strictly comply with data protection regulations to ensure that all image data is processed locally in the car and not transmitted to external servers unless the owner explicitly authorizes remote diagnosis or updates.

[0050] 2. Optical rainfall sensor module.

[0051] High-precision sensor: An all-in-one sensor with integrated light intensity and rainfall detection functions is used to simultaneously measure parameters such as direct light, scattered light, and raindrop velocity, providing the system with more comprehensive environmental data.

[0052] Calibration mechanism: The sensor needs to be strictly calibrated before leaving the factory to ensure the measurement accuracy under different weather conditions. At the same time, the system should have an automatic calibration function and regularly make fine adjustments based on standard light sources or known environmental conditions to maintain long-term measurement accuracy.

[0053] 3. CPU (Central Processing Unit)

[0054] High-performance processor: A low-power, high-performance embedded processor is selected as the CPU to receive and process data from the DMS and light and rainfall sensors. The processor must have sufficient computing power to support complex image recognition algorithms and real-time data analysis.

[0055] Intelligent decision-making algorithm: Based on the preset algorithm logic, the CPU conducts a comprehensive analysis of the received data to determine whether it is necessary to trigger the light barrier adjustment instruction. The algorithm needs to consider multiple factors, such as the duration of the driver's squinting, the rate of change of light intensity, the current vehicle speed and road conditions, etc., to make a more reasonable decision.

[0056] 4. Light barrier control unit.

[0057] Motor drive system: A silent and efficient DC motor is used as the power source of the light barrier, and a precise gear transmission device is used to achieve smooth lifting and lowering of the light barrier. The motor must have an overload protection function to prevent damage caused by unexpected situations.

[0058] Position feedback mechanism: A position sensor (such as a Hall sensor) is installed on the light shield to monitor the position information of the light shield in real time and feed the data back to the CPU. The CPU adjusts the motor speed and direction based on the feedback information to ensure that the light shield can accurately reach the specified position.

[0059] Manual backup: On the basis of automatic control, the function of manually controlling the light barrier is retained so that the driver can manually adjust the position of the light barrier in special circumstances (such as system failure).

[0060] Specifically, Figure 1 A schematic flow chart of a method for controlling a vehicle light shield provided in an embodiment of the present application.

[0061] like Figure 1 As shown, the control method of the vehicle light shield includes the following steps:

[0062] In step S101 , the current light intensity and the driver's facial image are acquired.

[0063] Specifically, the embodiment of the present application can continuously capture the driver's facial image through the DMS camera, collect at least dozens of frames of images per second for subsequent processing, and the image processing algorithm runs in real time on the CPU to perform face detection, eye recognition and squinting judgment on the image; and continuously monitor the ambient light intensity through the light and rain sensor, and send the data to the CPU at a fixed frequency (such as once per second), and the CPU updates the internal environment model based on the received data.

[0064] In step S102, the squinting duration of the driver is determined based on the facial image, and when the squinting duration is greater than a preset time threshold and the current light intensity is greater than a preset light threshold, the vehicle light shield is controlled to perform a sunshade action.

[0065] The preset time threshold and the preset light threshold may be preset by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, and are not specifically limited here.

[0066] Specifically, the embodiment of the present application uses the CPU to perform in-depth analysis on the data of the DMS and light and rain sensor. For the DMS data, it mainly focuses on the changing trend of the driver's eye state; for the light and rain data, it focuses on the absolute value and changing trend of the light intensity.

[0067] In the actual implementation process, Figure 2 As shown, based on the driver's squinting state, light intensity and preset threshold conditions (such as squinting duration exceeds X seconds and light intensity exceeds Y lux), the CPU determines whether to trigger the light baffle adjustment instruction. At the same time, the embodiment of the present application can also consider auxiliary factors such as vehicle speed and road conditions for fine-tuning.

[0068] Once the CPU makes a decision to adjust the light barrier, it sends a corresponding instruction to the light barrier control unit (such as "lower the light barrier to the 30% position"). After receiving the instruction, the light barrier control unit immediately starts the motor drive system to drive the light barrier to rise and fall in the specified direction and speed. During the lifting process, the position sensor feeds back the light barrier position information to the CPU in real time for precise control. When the light barrier reaches the specified position, the control unit sends a completion signal to the CPU. After the CPU confirms, the adjustment process ends and waits for the next trigger condition.

[0069] It should be noted that the embodiments of the present application can continuously collect facial image data of the driver under different lighting conditions for training and optimizing deep learning algorithms, and improve the accuracy and robustness of squinting detection by continuously iterating the algorithm model; for night or low-light environments, the DMS module can automatically switch to infrared night vision mode, using infrared light to capture the driver's facial contours and eye features to ensure safe monitoring during night driving.

[0070] In addition, the optical rain sensor needs to be calibrated before leaving the factory to prevent misjudgment due to inaccurate data. The optical rain sensor has a built-in self-diagnosis function that can automatically detect hardware failures and measurement errors. Once an abnormality is detected, a fault report is sent to the CPU and the owner is prompted to perform maintenance.

[0071] The light barrier adopts a smooth control algorithm during the lifting process to reduce the impact and noise when the motor starts and stops. At the same time, the smooth lifting and lowering of the light barrier is achieved by adjusting the motor speed and acceleration curve.

[0072] It should be noted by relevant technical personnel in the field that before the control system architecture of the vehicle light shield according to the embodiment of the present application is used, experimental simulation and actual road testing can be carried out.

[0073] 1. Experimental simulation.

[0074] Lighting simulation: A lighting simulation device is built in the laboratory to simulate changes in light intensity at different time periods (such as sunrise, noon, sunset, etc.) and in different weather conditions (such as sunny, cloudy, rainy, etc.). By adjusting the light intensity and direction of the simulation device, the response speed and accuracy of the system under different lighting conditions are tested.

[0075] Driver simulation: Use a puppet or virtual reality technology to simulate the driver's facial expressions and movements. Test the system's ability to recognize the driver's status through preset squinting movements and expression changes.

[0076] 2. Actual road test.

[0077] Test vehicle preparation: Select a representative test vehicle for modification and install all the hardware equipment and software programs of this system. Ensure that the test vehicle has passed the safety inspection and performance test before testing.

[0078] Test route planning: Plan test routes that include a variety of road and weather conditions (such as highways, urban roads, mountain roads, etc.) to comprehensively evaluate the performance of the system in different environments.

[0079] Tester arrangement: Organize a professional test team to conduct actual road tests. Testers must have extensive driving and vehicle testing experience and be able to accurately record and evaluate the performance of the system in actual use.

[0080] Data collection and analysis: During the test, various system operation data (such as the number of light barrier adjustment times, response time, driver feedback, etc.) are collected and analyzed in detail. By comparing the test data with the preset standards, the system performance is evaluated to see whether it meets the design requirements.

[0081] Optionally, in some embodiments, controlling the vehicle light shield to perform a sunshade action includes: determining the driver's identity information based on a facial image; based on the identity information, retrieving a first target position associated with the identity information from a preset database, and adjusting the vehicle light shield to the first target position.

[0082] Specifically, when the driver starts the vehicle, the DMS system in the vehicle captures the driver's facial image through a camera. The system uses facial recognition technology to compare the captured facial image with the driver's identity information in a preset database. It is assumed that the database stores the identity information of multiple drivers and their corresponding light-shield position preferences.

[0083] The system identifies the current driver as "Driver A" and retrieves the first target position associated with "Driver A" from the database. Assuming that "Driver A" is accustomed to adjusting the light shield to a specific angle and position to optimally block the sunlight and maintain a good line of sight, the system automatically controls the vehicle light shield and adjusts it to the first target position. For example, when the sunlight shines from the front, the light shield flips down and adjusts the angle to completely block the sunlight; if the sunlight shines from the side, the light shield will rotate to the corresponding side to achieve the best shading effect.

[0084] In this way, the intelligent light barrier can automatically adjust its position according to the driver's identity and habits, improving driving comfort and safety.

[0085] Optionally, in some embodiments, before retrieving the first target position associated with the identity information from a preset database and adjusting the vehicle light visor to the first target position, it includes: obtaining the user's editing information, the editing information including the user's identity information and the target position information associated with the user's identity information; and establishing a preset database based on the editing information.

[0086] Specifically, when the driver uses the vehicle for the first time, the system prompts the driver to register his identity, and the driver enters his identity information through the touch screen or voice assistant in the car. The driver can also set his own light shield position preference under different light conditions. For example, driver A may want to adjust the light shield to a specific angle when the sun is shining directly to best block the sun and maintain a good view.

[0087] The system stores the driver's identity information and the corresponding light shield position preference in a preset database. For example, the database records the light shield position information of "Driver A" under different light conditions. In addition, the database also supports multi-user settings and can store the identity information of multiple drivers and their corresponding light shield position preferences.

[0088] In addition, the vehicle light shield control system of the embodiment of the present application also has a memory function, which can remember the driver's preference setting for the light shield position, and automatically adjust the light shield to the position set by the driver last time when it is started next time.

[0089] Optionally, in some embodiments, the method further includes: obtaining a vehicle light shield adjustment instruction; determining a second target position according to the vehicle light shield adjustment instruction, and adjusting the vehicle light shield to the second target position.

[0090] Specifically, the driver may encounter different light conditions during driving and may need to manually adjust the position of the light shield. For example, when sunlight shines from the side, the driver may need to manually adjust the light shield to better block the sunlight.

[0091] The driver can issue a command to adjust the sunshade through the touchscreen, voice assistant or physical button in the car. For example, the driver can issue an adjustment command through a virtual button on the touchscreen or voice command "adjust the sunshade 30 degrees to the left".

[0092] After receiving the driver's adjustment command, the system determines the second target position based on the command content. For example, if the driver issues the command "adjust the light shield 30 degrees to the left", the system will calculate the specific position where the light shield needs to be adjusted. The system can also further optimize the position of the light shield based on the current light conditions and the driving state of the vehicle. For example, if the vehicle is driving at high speed, the system will automatically adjust the angle of the light shield to reduce wind resistance and improve driving stability.

[0093] Optionally, in some embodiments, controlling the vehicle sun visor to perform a sunshade action includes: generating a vehicle sun visor adjustment reminder instruction, and providing a reminder according to the vehicle sun visor adjustment reminder instruction.

[0094] Specifically, when the vehicle is driving, the DMS system monitors the light conditions in the cab in real time through the camera. If it detects that the sunlight is too strong and may affect the driver's vision, the system will automatically generate a reminder instruction to adjust the vehicle sun visor. For example, when the sunlight shines from the front and the light intensity exceeds the preset safety threshold, the system will generate a reminder instruction.

[0095] The system can use a variety of methods to remind the driver to adjust the light shield according to the generated reminder instructions. The reminder methods may include: (1) visual reminder: a reminder icon or text message is displayed on the dashboard or central control screen inside the vehicle, reminding the driver that the sunlight is too strong and suggesting to adjust the light shield; (2) auditory reminder: a voice prompt is issued through the speaker inside the vehicle, for example: "The sunlight is too strong, please adjust the light shield"; (3) tactile reminder: through the vibration function of the steering wheel or seat, a slight vibration reminds the driver to pay attention to adjusting the light shield.

[0096] Therefore, the embodiments of the present application have the following beneficial effects:

[0097] 1. Security is significantly improved.

[0098] Instant response: The system can respond the moment the driver squints due to strong light, and automatically adjust the light shield to block the strong light. This immediacy greatly reduces the time that strong light interferes with the driver's vision and reduces the risk of traffic accidents.

[0099] Comprehensive protection: The system not only pays attention to the impact of direct light, but also senses the impact of scattered light, rain and fog and other complex weather conditions on vision through the light and rain sensor. By comprehensively judging and adjusting the position of the light shield, the system can achieve all-round protection of the driver's vision.

[0100] 2. Comfort is greatly enhanced.

[0101] Personalized adjustment: The system can be personalized according to the individual differences and driving habits of the driver. For example, for drivers who are sensitive to light, the system can adjust the light shield in advance to reduce their discomfort; for drivers who like bright vision, the light shield can be reduced while ensuring safety.

[0102] Reduced Fatigue: Automatically adjusting the light barrier reduces driver distraction and fatigue caused by manually adjusting the light barrier while driving. This helps maintain driver focus and alertness, improving overall driving comfort.

[0103] 3. Intelligent operation experience.

[0104] Seamless integration: As part of vehicle intelligence, the system is seamlessly integrated with other intelligent systems of the vehicle (such as navigation system, autonomous driving system, etc.) to achieve a more intelligent and efficient driving experience by sharing data and resources.

[0105] User-friendly: The system interface is simple and easy to operate. The driver can set and modify the light barrier preferences through simple operations. At the same time, the system also has a voice control function, which further enhances the user experience.

[0106] According to the control method of the vehicle light shield proposed in the embodiment of the present application, by obtaining the current light intensity and the driver's facial image, and determining the driver's squinting time according to the facial image, when the squinting time is greater than the preset time threshold and the current light intensity is greater than the preset light threshold, the vehicle light shield is controlled to perform the sunshade action. The present application uses a driver monitoring system to monitor the driver's status, and then uses data such as the on-board light and rain sensor to determine whether the driver is exposed to strong light, and automatically lowers the light shield for the driver, thereby solving the problem that manually adjusting the sun visor easily distracts the driver and causes safety accidents, freeing the driver's hands and improving driving safety.

[0107] Next, the control device for the vehicle light shield proposed in the embodiment of the present application is described with reference to the accompanying drawings.

[0108] Figure 3 It is a block diagram of a control device for a vehicle light shield according to an embodiment of the present application.

[0109] like Figure 3 As shown, the control device 10 of the vehicle light barrier includes: an acquisition module 100 and a control module 200 .

[0110] The acquisition module 100 is used to acquire the current light intensity and the driver's facial image.

[0111] The control module 200 is used to determine the driver's squinting time according to the facial image, and control the vehicle's light shield to perform a sunshade action when the squinting time is greater than a preset time threshold and the current light intensity is greater than a preset light threshold.

[0112] Optionally, in some embodiments, the control module 200 includes: a determination unit and a regulation unit.

[0113] Wherein, the determination unit is used to determine the identity information of the driver based on the facial image.

[0114] The adjustment unit is used to retrieve a first target position associated with the identity information from a preset database according to the identity information, and adjust the vehicle light shield to the first target position.

[0115] Optionally, in some embodiments, before retrieving the first target position associated with the identity information from a preset database and adjusting the vehicle light shield to the first target position, the adjusting unit includes: an acquiring subunit and an establishing subunit.

[0116] The acquisition subunit is used to acquire the user's editing information, and the editing information includes the user's identity information and the target location information associated with the user's identity information.

[0117] A subunit is established to establish a preset database according to the edited information.

[0118] Optionally, in some embodiments, the method further includes: a second acquisition unit and an adjustment unit.

[0119] The second acquisition unit is used to acquire the vehicle light shield adjustment instruction.

[0120] The adjusting unit determines a second target position according to the vehicle light shield adjustment instruction, and adjusts the vehicle light shield to the second target position.

[0121] Optionally, in some embodiments, the control module 200 includes: a reminder unit.

[0122] Among them, the reminder unit is used to generate a vehicle sun visor adjustment reminder instruction and to give a reminder according to the vehicle sun visor adjustment reminder instruction.

[0123] It should be noted that the aforementioned explanation of the embodiment of the method for controlling the vehicle light shield is also applicable to the control device for the vehicle light shield of this embodiment, and will not be repeated here.

[0124] According to the control device of the vehicle light shield proposed in the embodiment of the present application, by obtaining the current light intensity and the driver's facial image, and determining the driver's squinting time according to the facial image, when the squinting time is greater than the preset time threshold and the current light intensity is greater than the preset light threshold, the vehicle light shield is controlled to perform the sunshade action. The present application monitors the driver's status through the driver monitoring system, and then uses the data of the vehicle-mounted light and rain sensor to determine whether the driver is exposed to strong light, and automatically lowers the light shield for the driver, thereby solving the problem that manually adjusting the sun visor easily distracts the driver and causes safety accidents, freeing the driver's hands and improving driving safety.
