Description
Technical Field
[0001] This invention relates to the field of vehicle control technology, and specifically to a vehicle control method, system, and intelligent sun-protective vehicle based on the human body's sun protection needs. Background Technology
[0002] With rising global temperatures and increasing consumer demand for driving comfort, automotive sun protection technology has evolved from traditional physical sunshade methods (such as sunshades and car covers) to intelligent material science solutions and smart control systems. Modern automotive sun protection technology integrates innovative materials such as electrochromic glass (EC) and nano-matrix light-adjusting technology (NMAT), enabling sunroofs to switch light transmittance quickly and achieve high UV blocking rates. Furthermore, some high-end models incorporate silver-plated glass technology to further enhance UV blocking efficiency.
[0003] Existing technologies face challenges such as high costs and inconsistent regulations and standards. EC / NMAT technology, due to its complex materials and manufacturing processes, increases the cost per vehicle by several thousand yuan, hindering its widespread adoption.
[0004] Current regulations, such as the China New Car Assessment Program (C-NCAP), do not mandate sun protection performance testing, leaving some automakers without the incentive to upgrade their technology. Furthermore, traditional physical sunshades (such as car covers and window tints) suffer from issues like obstructed visibility and aging failure, while intelligent dimming technology relies on high-precision sensors and lacks stability in extreme environments (such as sandstorms and low temperatures), making it difficult to provide users with a dynamically adjustable intelligent sun protection experience that meets their individual sun protection needs.
[0005] Therefore, the existing technology still needs further development. Summary of the Invention
[0006] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a vehicle control method, system and intelligent sun protection vehicle based on human sun protection needs, which can dynamically provide users with an intelligent sun protection experience.

The target window is determined by the direction of sunlight.
[0013] As an optional implementation, the dynamic light management unit is at least used to adjust the opening degree of each window and gradually adjust the ultraviolet blocking rate of the dimming component in advance at a predetermined time when the altitude, solar altitude angle, ground reflectance index and direction of sunlight entering the vehicle, which affect the ultraviolet index of each window, change significantly in the driving route information, in order to adapt to the upcoming changes in lighting conditions.
[0014] As an optional implementation, the dynamic light management unit further includes a driving scene dimming subunit, which is used at least to control the transmittance adjustment of the dimming component by taking three-dimensional variables of light intensity, time and geographical location as input parameters and combining them with pre-stored typical environmental change scenarios, so as to achieve a smooth transmittance transition in scenarios where the vehicle enters and exits the scene of drastic changes in light.

[0022] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.
[0023] It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment in the following embodiments have their own emphasis; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0024] EC dimming technology (electrochromic): An electrochromic material layer (such as tungsten trioxide, Prussian blue, etc.) is sandwiched between two layers of transparent conductive glass (such as ITO). By applying voltage to drive ion migration, the redox reaction of the material is triggered, and the ultraviolet blocking rate is reversibly changed (usually 15%-75%).
[0025] NMAT technology (Nano Matrix Dimming): Based on the upgraded architecture of PDLC (Polymer Dispersed Liquid Crystal), it achieves optical path control through the arrangement of nanoscale particle matrices.
[0026] Early EC glass required over 10 seconds to switch light transmittance, impacting user experience. While NMAT offers a response time as fast as 0.1 seconds, it consumes more energy and relies on solar power. Side and rear windows generally have lower UV blocking rates than the windshield (e.g., traditional side windows have UVA transmittance >80%), and the films are prone to aging and peeling. Some technologies (such as silver-plated glass) may also interfere with vehicle signal transmission, requiring additional optimization of the coating process. These technologies are only used in single components (such as the windshield or sunroof), lacking system-level integration solutions, making it difficult to provide users with a dynamically adjustable intelligent sun protection experience that meets their individual sun protection needs.
[0027] like Figure 1 As shown, the first aspect of the present invention provides a vehicle control method based on the human body's sun protection needs, including the following steps.
[0028] Step S100: Obtain the UV index inside the vehicle corresponding to the driver's seat.
[0029] In step S100, obtaining the in-vehicle UV index corresponding to the driver's seat includes the following:
[0030] The vehicle's UV index is obtained through in-vehicle UV sensors. Multiple sensors can be used to obtain the actual UV value for the driver's seat. However, since car windows can only block directly entering UV rays, UV rays can still enter through open windows. Therefore, it is impossible to monitor the UV index for all seats; only the UV index for the driver's seat can be monitored.
[0031] The UV index outside the vehicle is also obtained through UV sensors outside the vehicle.
[0032] The three most critical factors affecting the UV index are: altitude, solar altitude angle, and surface reflection.
[0033] Based on three factors—altitude, solar elevation angle, and surface reflection—the system predicts the UV value along the navigation route using the current external UV value. When a sudden change in UV value is predicted, the system can adjust the closing of the windows and the UV blocking rates of the windows, windshield, rear window, and sunroof in advance.
[0034] Specifically, this invention acquires relevant data through GPS, navigation APP, LiDAR, and four UV sensors, and its main contents include the following.
[0035] A high-precision UV sensor is integrated on the roof (outside the vehicle) to acquire the UVI_OUT outside the vehicle.
[0036] Three high-precision UV sensors are installed around the driver's seat, on the windshield, the left front window, and between the driver and passenger seats. These sensors are adapted to the driver's seat and are in-vehicle UV sensors that can establish a UV index model for the driver's seat and obtain the driver's UVI_IN.
[0037] Get the current time (including UTC time) and date by time.
[0038] The altitude value h_cur is obtained by using the vehicle's GPS data.
[0039] The vehicle's latitude and longitude information is obtained through its own GPS data.
[0040] Ozone layer thickness (o) values are obtained through the ozone monitoring API.
[0041] Surface information values are obtained through lidar.
[0042] The window module obtains the opening status (including the degree of opening) of each of the four windows.
[0043] The sunroof module is used to obtain the sunroof's opening status (including the degree of opening).
[0044] The system acquires the driver's personal information, such as skin color and skin exposure, through a camera. Skin color / exposure can also be an optional input. The core solution can still be achieved solely through UVI and threshold closed-loop control.
[0045] The vehicle's direction of travel is obtained through the vehicle's direction sensor.
[0046] By using the vehicle's GPS latitude and longitude information, the current date and time (including UTC time), and matching the driving direction, the direction of sunlight entering the vehicle can be predicted.
[0047] Sunlight coming from the front: relative angle between [-45°, 45°] (sun in the direction of the car's front).
[0048] Rear-facing sunlight: relative angle between [135°, 180°] or [-180°, -135°] (sun at the rear of the vehicle).
[0049] Sunlight entering from the left: relative angle between [-135°, -45°] (sun on the left side of the vehicle).
[0050] Sunlight entering from the right: relative angle between [45°, 135°] (sun on the right side of the vehicle).
[0051] Step S200: Identify and obtain the corresponding ultraviolet safety threshold based on the driver's identity.
[0052] Currently, the UV levels inside and outside the vehicle can be directly obtained through UV sensors. However, it is necessary to predict the UV levels along the navigation route based on the UV levels outside the vehicle. If the UV levels suddenly change and the direction of sunlight entering the vehicle changes (the direction of sunlight entering the vehicle includes the front, left, right, or rear of the vehicle), it is necessary to dynamically adjust the opening degree of the windows and the UV blocking rate of the windows.
[0053] Specifically, the occupant identity information includes age, gender, and / or skin color type, and the ultraviolet safety threshold is adjusted by the user through the vehicle's human-machine interface based on the occupant's skin sensitivity and exposed area to meet individual sun protection preferences.
[0054] For example, the threshold is stored in the vehicle-side database and / or cloud account and is bound to the identity ID; a default threshold is used when it is not recognized; users can adjust and override it through the HMI.
[0055] Those skilled in the art can independently adjust, merge, or split more detailed divisions according to the needs of the target drivers and passengers, such as separately dividing children into infants and preschool children, or separately dividing adults into age groups, to better protect users' requirements for sun protection effects, while still falling within the scope of protection of this invention.
[0056] Furthermore, configuring an interactive interface or other interactive ports provides users with an entry point to ensure that users can adjust independently, and can provide a sun protection effect that is more in line with user experience for people who prefer stronger protection.
[0057] In this way, the present invention can achieve sun protection triggering for the driver, improve the user's driving experience, reduce uncomfortable situations such as excessive or insufficient sun protection, and improve the accuracy of sun protection control and user comfort.
[0058] Step S300: Compare the UV index inside the driver's vehicle with the corresponding UV safety threshold. When the UV index inside the driver's vehicle is greater than the threshold, generate a control command to close or reduce the target window to a preset opening degree, and increase its UV blocking rate through the corresponding window's dimming component until the UV index inside the driver's vehicle drops to no higher than the corresponding UV safety threshold. The target window is determined by the direction of sunlight.
[0059] In one embodiment of the present invention, the method further includes step S400: when the altitude, solar altitude angle, surface reflectance index and direction of sunlight entering the vehicle that affect the ultraviolet index of each window in the driving route information change significantly, the opening degree of each window is adjusted in advance at a predetermined time and the ultraviolet blocking rate of the dimming component is gradually adjusted to adapt to the upcoming changes in lighting conditions.
[0060] Specifically, the vehicle's direction sensor is used to obtain the vehicle's driving direction. Combined with the vehicle's GPS latitude and longitude information, the current date and time (including the UTC time of the time zone), and the driving direction, the direction of sunlight entering the vehicle is predicted.
[0061] Sunlight coming from the front: relative angle between [-45°, 45°] (sun in the direction of the car's front).
[0062] Rear-facing sunlight: relative angle between [135°, 180°] or [-180°, -135°] (sun at the rear of the vehicle).
[0063] Sunlight entering from the left: relative angle between [-135°, -45°] (sun on the left side of the vehicle).
[0064] Sunlight entering from the right: relative angle between [45°, 135°] (sun on the right side of the vehicle).
[0065] In one embodiment of the present invention, the step of adjusting the opening degree of each vehicle window in advance at a predetermined time and gradually adjusting the ultraviolet blocking rate of the dimming component to adapt to the upcoming change in lighting conditions includes: Using three-dimensional variables of light intensity, time, and geographical location as input parameters, and combining them with pre-stored typical environmental change scenarios, the transmittance of the dimming component is controlled to achieve a smooth transmittance transition in scenarios with drastic changes in light, such as vehicles entering and exiting tunnels, in shady areas, and in open areas. The light intensity is inferred by obtaining the laser reflection intensity at a preset distance in front, such as 200 meters ahead, through the vehicle's lidar sensor.
[0066] Specifically, this implementation method mainly relies on lidar and light sensors to infer light intensity based on the correspondence between lidar and light sensors.
[0067] For example, under a clear midday sky, the reflectivity of the lidar is 8500, and the illuminance sensed by the light sensor is 110000.
[0068] Scenario 1: 200m before entering the tunnel, the reflectivity of the lidar is 1200, which means the light intensity inside the tunnel is 15529. We need to increase the light transmittance of each glass according to the light intensity at this time.
[0069] Scenario 2: 200m before entering the snow, the reflectivity of the lidar is 9200, which means the light intensity in the snow is 119059. We need to reduce the light transmittance of the glass based on the light intensity at this time.
[0070] It should be noted that the regulations have requirements for the light transmittance of the windshield (greater than 70%) and the front side windows, and adjustments must be made within the range required by the regulations.
[0071] Here, the present invention can automatically plan the dimming timing (such as starting the gradual dimming 10 seconds before entering the tunnel).
[0072] In one embodiment of the present invention, when the UV index inside the driver's vehicle is greater than its threshold, the left front window and sunroof are closed first, and the UV blocking rate of the other three windows and the rear window is adjusted according to the direction of sunlight entering the vehicle using EC / NMAT technology to ensure that the UVI value of the driver's vehicle is less than the corresponding UVI threshold.
[0073] In one embodiment of the present invention, a three-level dynamic protection system is set up to better meet the needs of the driver's driving mode.
[0074] The three-level dynamic protection system consists of three modes, specifically MAX mode, AUTO mode and LITE mode. For example, UVI ≤ 0.7 in MAX mode, UVI ≤ 2 in AUTO mode and UVI ≤ 5 in LITE mode.
[0075] like Figure 2 As shown, in the first application scenario of this invention, the initial scenario is driving in a sunny midday scene with a vehicle external UVI value of 7. The following is the adjustment process for each mode.
[0076] 1. For MAX mode: a. Immediately close all car windows; b. At the same time, the barrier properties of all glass must reach 99.9%.
[0077] 2. For AUTO mode: a. Close the right front window; b. Based on the direction of the sun's rays: If the sun shines in from the left, the left rear window must be completely closed; If the sun is shining in from the right, and the right rear window is open, adjust the right rear window to ensure the opening is less than 50%. If the sun is shining in from the rear, and only one of the two rear windows (left and right) is open, adjust that window to ensure the opening is less than 50%. If the sun is shining in from the rear, and both the left and right rear windows are open, check the UV index for each side. Close the window on the side with the higher index, and adjust the other window to ensure it is less than 40% open.
[0078] 3. For LITE mode: Based on the direction of the sun's rays: If the sun is shining in from the front, and the left front window is open, adjust the left front window to ensure the opening is less than 50%. If the sun is shining from the left, and the left rear window is open, adjust the left rear window to ensure the opening is less than 50%. If the sun is shining from the right, and the right front window is open, adjust the right front window to ensure the opening is less than 50%. If the sun is shining in from the rear, and both the rear left and rear right windows are open, adjust the rear left and rear right windows to ensure that the opening is less than 50%.
[0079] In the second application scenario of this invention, the dynamic protection logic for the subsequent dynamic driving scenario is as follows.
[0080] There are three key factors affecting the UV index: solar altitude angle, surface reflectance, and altitude. The solar altitude angle θfut is calculated by obtaining the estimated time, date, and expected latitude and longitude of the navigation route from the navigation app; the expected altitude h_fut is obtained from the navigation route from the navigation app; and the surface reflectance of the first 200 meters is obtained from lidar, and the external UVI value of the navigation route is calculated in real time using the following formula: UVI_OUT_pred=UVI_OUT_cur× ; P: Sun angle correction index, typically 1.15 ± 0.05; UVI_OUT_cur: The measured UV index at the vehicle's current location; UVI_OUT_pred: The UVI value of the expected target location for the navigation route; : Current solar altitude angle; The solar altitude angle of the target location on the navigation route; R_cur: Surface reflectance at the current location; R_fut: Surface reflectance at the target location of the navigation route; ∆h: The elevation difference between the expected target location and the current location; The system obtains the expected direction of the vehicle's journey from the navigation app's route, and then calculates the direction from which the sun shines into the vehicle.
[0081] In addition, since the direction in which the sun shines into the car affects the opening degree of the windows and the ultraviolet blocking rate of the windows, the opening degree of the four windows and the sunroof, as well as the ultraviolet blocking rate of the windshield, rear window, sunroof and the four windows are dynamically adjusted based on the direction in which the sun shines.
[0082] If the predicted external UVI value is greater than 8, switch to MAX mode.
[0083] In scenario three of this invention, the light transmittance adjustment logic for the windshield and the front left and right windows during subsequent dynamic driving is as follows: This system primarily relies on lidar and light sensors. Therefore, the light intensity is inferred based on the correspondence between lidar and light sensors. For example, at midday on a clear sky, the lidar's reflected intensity is 8500, and the light sensor detects an illuminance of 110000. 200 meters before entering a tunnel, the lidar's reflected intensity is 1200, indicating the inferred light intensity inside the tunnel is 15529. We need to gradually increase the transmittance of each pane of glass to its maximum based on this light intensity. 200 meters before entering snowy terrain, the lidar's reflected intensity is 9200, indicating the inferred light intensity in the snow is 119059. We need to reduce the transmittance of the glass to a minimum of 70% based on this light intensity.
[0084] like Figure 3 As shown, a second aspect of the present invention provides a vehicle control system based on human sun protection needs, comprising: The demand sensing unit is used at least to obtain the in-vehicle UV index corresponding to the driver's seat. The data analysis unit is used at least to obtain the corresponding ultraviolet safety threshold based on the driver's identity; The dynamic light management unit is used to compare the UV index inside the driver's vehicle with the corresponding UV safety threshold. When the UV index inside the driver's vehicle is greater than the threshold, a control command is generated to close or reduce the target window to a preset opening. The UV blocking rate is increased by the dimming component of the corresponding window until the UV index inside the driver's vehicle drops to no higher than the corresponding UV safety threshold. The target window is determined by the direction of sunlight.
[0085] In one embodiment of the present invention, the dynamic light management unit is at least used to adjust the opening degree of each window and gradually adjust the ultraviolet blocking rate of the dimming component in advance at a predetermined time when the altitude, solar altitude angle, ground surface reflectance index and the direction of sunlight entering the vehicle, which affect the ultraviolet index of each window, change significantly in the driving route information, so as to adapt to the upcoming change in lighting conditions.
[0086] It should be noted that, in this invention, significant changes can be set by establishing a certain threshold or ratio; the predetermined time can be set, for example, 10 seconds before entering the scene, and captured by rules; smooth transitions can be limited, for example, by limiting the slope of the transmittance change. All of the above are clearly described, and those skilled in the art can set or process them according to actual conditions, all of which fall within the scope of protection of this invention.
[0087] In one embodiment of the present invention, the dynamic light management unit further includes a driving scene dimming subunit, which is at least used to control the light transmittance adjustment of the dimming component by taking three-dimensional variables of light intensity, time and geographical location as input parameters and combining them with pre-stored typical environmental change scenarios, so as to achieve a smooth light transmittance transition in scenarios where the vehicle enters and exits the scene of drastic changes in light.
[0088] In one embodiment of the present invention, the dynamic light management unit further includes: Using the vehicle's GPS latitude and longitude information, the current date and time, and the driving direction, the direction of sunlight entering the vehicle is predicted. The direction of sunlight entering the vehicle includes at least the front, rear, left, and right sides. A significant change occurs if any of the directions of incoming fire—front, rear, left, and right—changes to other directions.

[0090] A fourth aspect of the present invention discloses a readable storage medium storing a computer program, which is executed by a processor as described in any of the above embodiments.
[0091] Computer-readable storage media can include: any entity or device capable of carrying computer programs, recording media, USB flash drives, portable hard drives, magnetic disks, optical disks, computer memory, read-only memory, random access memory, and software distribution media, etc. Computer programs include computer program code. Computer program code can be in the form of source code, object code, executable files, or some intermediate form, etc. Computer-readable storage media can include: any entity or device capable of carrying computer program code, recording media, USB flash drives, portable hard drives, magnetic disks, optical disks, computer memory, read-only memory, random access memory, and software distribution media, etc.
