Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile rainproof devices, and in particular to a vehicle-mounted air umbrella adjusting method, device, equipment and storage medium. BACKGROUND

[0002] With the explosive popularity of the connected car industry, user experience has become a key factor in deciding to buy a car. In rainy days, when the driver and passengers get in and out of the vehicle, they need to fold or open the umbrella at the door, and in this process, the personnel are easy to be wet, and raindrops may also drift into the car, causing a bad experience. The air flow nozzle of the existing vehicle-mounted air umbrella device is usually loaded on the top of the door. In the case of small air flow injection angle or small air injection speed, this design may blow rainwater into the car. This is because when the air flow is ejected at a small angle or speed, it cannot form an effective air curtain to block the rainwater, but may blow the rainwater away and bring it into the car, causing discomfort to the driver and passengers and wetness in the car. With the opening and closing of the door, the rain-shielding range of the air umbrella will change. This is because the position and injection direction of the air flow nozzle are fixed, and when the door is opened, the distance between the air flow nozzle on the top of the door and the driver and passengers changes, causing the coverage range of the air curtain to change. This change may cause the driver and passengers to still be wet when getting in and out of the vehicle, thereby reducing the practicability of the air umbrella. The existing vehicle-mounted air umbrella device usually lacks an intelligent adjusting system and cannot automatically adjust the air injection intensity, angle and duration of the air flow nozzle according to the rain intensity, wind direction, vehicle speed and other external environmental factors. This causes the air umbrella to be unable to provide the best rain-shielding effect in different weather conditions. For example, in heavy rain, if the air injection intensity of the air flow nozzle is not large enough, it cannot form an effective air curtain to block the rainwater; and in light rain, if the air injection intensity is too large, it may cause unnecessary energy consumption and noise. Due to the lack of an intelligent adjusting system, the existing vehicle-mounted air umbrella device usually needs to be manually operated by the driver and passengers to turn on or off. Such manual operation is not only cumbersome, but also may increase the difficulty and inconvenience of operation in rainy conditions. In addition, manual operation may also cause operation errors or omissions, thereby reducing the reliability and practicability of the air umbrella.

[0003] The existing vehicle-mounted air umbrella device is usually disconnected with the intelligent system of the vehicle, and cannot be seamlessly connected with other intelligent functions of the vehicle (such as navigation, entertainment, driving assistance, etc.). This results in that the air umbrella cannot match the overall intelligent level of the vehicle in terms of function and user experience, thereby reducing its market competitiveness. Modern cars are usually equipped with various environmental perception sensors (such as rain sensors, wind speed sensors, cameras, etc.), which can monitor the external environment in real time and provide accurate data support for the vehicle. However, the existing vehicle-mounted air umbrella device usually lacks these environmental perception capabilities and cannot automatically adjust the working state of the air flow nozzle according to real-time data. This results in that the air umbrella cannot provide the best rain-shielding effect when facing complex and changeable weather conditions. SUMMARY

[0004] The main purpose of the present application is to provide a vehicle-mounted air umbrella adjusting method, device, equipment and storage medium, which aims to solve the problem of unreasonable air flow nozzle of the air umbrella and limited rain-shielding range of the prior art.

The relevant commands can also be manually adjusted on the car machine and mobile phone APP to start and stop the air umbrella, adjust the angle and rain-shielding range of the air umbrella, and meet the needs of different regions and different scenes.

In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0043] It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0044] The application provides a vehicle-mounted air umbrella adjusting system, which aims to form an effective rain-shielding air curtain by precisely controlling the jet speed and angle of the air jet nozzle, so as to protect the driver and passengers from being drenched by rain when getting off the vehicle in rainy days, and prevent rainwater from entering the vehicle. The system integrates a vehicle-mounted system and a mobile phone APP system, both of which have the same functions, and the user can operate either one.

[0045] The user clicks the "air umbrella" button on the operation page of the vehicle machine or the mobile phone APP to start the air umbrella function. If the vehicle machine is started, it directly enters the air umbrella starting step; if the mobile phone APP is started, the APP sends an MQTT message to the vehicle machine TBOX, and the TBOX enters the air umbrella starting step after receiving the message. The vehicle machine starts the vehicle-mounted air umbrella processor module function through the CAN signal. The vehicle machine starts the rain detection device to detect whether it is raining and the rain amount, and transmits the rain amount information to the central processor. The central processor calculates the included angle A of the air jet nozzle jet and the horizontal plane and the jet speed V according to the rain amount information. The calculation formula is as follows:

[0046] Included angle A = E1*arctan(2-h);

[0047] Wherein, h is the height difference (m) between the air jet nozzle and the ground, and E1 is the correction coefficient (0.9-1.3, and the default is 1). The jet speed V = E2*(2+0.6*S), wherein S is the rain amount (grams per square centimeter per second), and E2 is the correction coefficient (0.8-1.2, which is adjusted according to the temperature and altitude, and the default is 1). The air umbrella function runs, and the air jet nozzle starts to jet, forming a rain-shielding air curtain. If the vehicle machine is closed, it directly enters the air umbrella closing step; if the mobile phone APP is closed, the APP sends an MQTT message to the vehicle machine TBOX, and the TBOX enters the air umbrella closing step after receiving the message. The vehicle machine closes the vehicle-mounted air umbrella processor module function through the CAN signal. The air jet nozzle stops jetting.

[0048] The user clicks the "adjust umbrella angle" button on the operation page of the car machine or mobile phone APP, and starts to adjust the air umbrella angle. The air umbrella processor receives the angle information and activates the airflow nozzle angle adjustment function. The processor adjusts the elevation angle between the airflow nozzle and the horizontal plane according to the angle information. The user clicks the "adjust umbrella angle" button on the operation page of the car machine or mobile phone APP (note: the button name may need to be changed to a more explicit "adjust rain shelter range" button to avoid confusion). The user selects to increase or decrease the range. If adjusted through the mobile phone APP, the APP sends an MQTT message to the car machine TBOX. After receiving the message, the air umbrella processor of the car receives the range information and activates the airflow nozzle speed adjustment function. The processor adjusts the jet speed according to the range information. If the range needs to be increased, the jet speed is increased; if the range needs to be decreased, the jet speed is decreased. Since the flowchart cannot be directly displayed, but according to the above description, the corresponding flowchart can be drawn. The flowchart of each function should include the starting point, each operation step, the decision point (such as selecting to increase / decrease the angle or range), the execution action (such as sending a message, starting / closing the processor, adjusting the angle / speed), and the ending point. The flowchart should be clear and easy to understand and operate for the user. In actual operation, the user needs to ensure that the connection between the car machine and the mobile phone APP is normal to ensure accurate transmission and execution of instructions. The settings of correction coefficients E1 and E2 need to be adjusted according to the actual situation to achieve the best rain shelter effect. When adjusting the air umbrella angle and rain shelter range, the user should observe the adjustment results and adjust in time as needed to ensure the effectiveness and stability of the rain shelter air curtain.

[0049] The present application proposes a first embodiment of a vehicle-mounted air umbrella adjustment method, please refer to Figure 1 , which includes steps S10-S30:

[0050] Step S10, the vehicle-mounted air umbrella detects the current rainfall through the rain detection device;

[0051] Step S20, according to the current rainfall, the vehicle-mounted air umbrella calculates the jet speed and jet angle of the airflow nozzle;

[0052] Step S30, the vehicle-mounted air umbrella controls the airflow nozzle to form a rain-shielding air curtain for rain sheltering according to the jet speed and jet angle.

[0053] It should be noted that in this embodiment, by precisely controlling the jet speed and jet angle of the airflow nozzle, an effective rain-shielding air curtain is formed to protect the driver and passengers from being wet by rain when getting off the car in rainy days, and to prevent rainwater from entering the car. This method combines the rain detection device, central processor and precise control of the airflow nozzle, realizing intelligent air umbrella adjustment. The following is a detailed description of the above steps:

[0054] Step S10: Detect the current rainfall using the rain detection device. The rain detection device is one of the core components of the vehicle-mounted air umbrella adjustment system, and its main function is to monitor the rainfall in the external environment in real time. This device usually uses advanced sensor technology to accurately perceive the size, density, and falling speed of raindrops, and then calculates the current rainfall. The working principle of the rain detection device is based on optical, capacitive, or piezoelectric sensor technology. Taking the optical sensor as an example, when raindrops fall on the sensor surface, they change the propagation path or reflection intensity of light, triggering the internal circuit of the sensor to generate an electrical signal. This electrical signal, after amplification and processing, can be converted into rainfall information. Once the rain detection device detects rainfall, it will immediately transmit this information to the central processor. After receiving the rainfall information, the central processor will perform further processing and analysis to provide accurate data support for subsequent jet speed and jet angle calculations. When using the rain detection device, ensure that its surface is clean and free of dirt to avoid affecting detection accuracy. Regularly calibrate and maintain the rain detection device to ensure its long-term stable operation.

[0055] Step S20: Calculate the jet speed and jet angle of the air jet nozzle according to the current rainfall. The central processor is another core component of the vehicle-mounted air umbrella adjustment system, which is responsible for receiving the rainfall information transmitted by the rain detection device and calculating the appropriate jet speed and jet angle of the air jet nozzle according to the preset algorithm or model. The central processor will consider multiple factors when calculating the jet speed and jet angle, including rainfall size, height difference between the air jet nozzle and the ground, correction coefficient, etc. Generally, the jet speed V is proportional to the rainfall S, that is, the greater the rainfall, the faster the jet speed. At the same time, the jet speed will be affected by the correction coefficient E2, which is used to adjust the proportional relationship between the jet speed and the rainfall. The jet angle A is related to the height difference h between the air jet nozzle and the ground and the correction coefficient E1. Generally speaking, the greater the height difference h, the smaller the jet angle A; conversely, the smaller the height difference h, the larger the jet angle A. At the same time, the correction coefficient E1 is used to fine-tune the jet angle to ensure that the air curtain can cover the required rain-shielding range. The calculation formula is:

[0056] A = E1 * arctan(f(h))

[0057] where f(h) is a function of the height difference h, and E1 is the correction coefficient. When calculating the jet speed and jet angle, ensure that the algorithm or model used is accurate and reliable to avoid excessive errors. The correction coefficients E1 and E2 should be adjusted according to actual conditions to achieve the best rain-shielding effect.

[0058] Step S30: Control the air flow nozzle to form a rain-shielding air curtain by spraying air at a certain speed and angle. The air flow nozzle is the actuator of the vehicle-mounted air umbrella adjustment system, which is responsible for converting high-pressure gas into high-speed airflow and forming a rain-shielding air curtain through specific air speed and angle. The air flow nozzle is usually composed of a nozzle body, an air flow channel, and an adjustment mechanism. After calculating the appropriate air speed and angle in step S20, the central processor will transmit these parameters to the adjustment mechanism of the air flow nozzle through control signals. After receiving the control signal, the adjustment mechanism will immediately adjust the air speed and angle of the air flow nozzle to ensure that the air curtain can form as required. When the air flow nozzle sprays air at the calculated speed and angle, a continuous air curtain is formed around the vehicle. This air curtain has a certain thickness and strength, which can effectively block the intrusion of raindrops. At the same time, since the air curtain is dynamic, it can adapt to changes in rainfall to ensure the stability and reliability of the rain-shielding effect.

[0059] It is particularly important to ensure that the pressure and flow of the gas are stable and reliable when controlling the air flow nozzle to spray air, so as to avoid affecting the formation effect of the air curtain. Regular cleaning and maintenance of the air flow nozzle are necessary to ensure that the internal channel is unobstructed and to avoid affecting the air spraying effect due to blockage.

[0060] Based on the first embodiment of the present application, the same or similar content as the above-mentioned embodiment one can refer to the above introduction, and the following will not be repeated. Please refer to Figure 2 In this embodiment, the step of detecting the current rainfall by the vehicle-mounted air umbrella through the rain detection device further includes:

[0061] Step S11: Start the air spraying rain-shielding function of the vehicle-mounted air umbrella by obtaining the button information of the function page.

[0062] Step S12: After receiving the start signal, the vehicle-mounted air umbrella detects the rainfall through the rain detection device.

[0063] Specifically, in this embodiment, the whole process of starting the air spraying rain-shielding function by the user and detecting the rainfall by the rain detection device is introduced. This process not only embodies the convenience of user interaction, but also ensures that the system can accurately and timely respond to environmental changes to provide effective rain-shielding protection for the driver and passengers. The following is a detailed description of the above steps:

[0064] Step S11: Start the air-jet rain-avoiding function through the button on the function page. The function page is an important part of the user interface of the vehicle-mounted air-cushion adjusting system, providing an intuitive and easy-to-use operation interface for users. On this page, users can easily find and operate the start button of the air-jet rain-avoiding function. The start button of the air-jet rain-avoiding function is usually designed as a prominent icon or text label, so that users can quickly identify and operate it. The style, color, and position of the button are carefully designed to ensure good visibility and operability under different lighting conditions. When the user needs to start the air-jet rain-avoiding function, the user first enters the function page through the main interface or shortcut entry of the vehicle-mounted system. On the function page, the user needs to find the start button of the air-jet rain-avoiding function and confirm its current state (such as whether it is in a clickable state). Once the button is confirmed to be in a clickable state, the user only needs to touch the button on the screen to start the air-jet rain-avoiding function. When the user clicks the start button, the vehicle-mounted system will immediately generate a start signal and transmit it to the central processor. After receiving the start signal, the central processor will immediately enter a standby state, ready to receive rainfall information from the rain detection device and calculate the air-jet speed and angle based on this information. When designing the function page, the style and position of the button should be designed to conform to the user's usage habits to improve operation efficiency and user experience. After the user clicks the start button, the system should provide clear feedback (such as a pop-up prompt or a change in button color) to confirm that the function has been successfully started.

[0065] Step S12: After receiving the start signal, the rain detection device detects the rainfall. In step S11, the user starts the air jet rain-avoiding function through the button on the function page and generates a start signal. After this signal is transmitted to the central processor, the central processor will immediately enter a standby state, ready to receive rainfall information from the rain detection device. After receiving the start signal, the rain detection device will immediately enter a working state. This means that the sensor will start real-time monitoring of the rainfall in the external environment and transmit the monitored data to the central processor. To ensure the accuracy of the detection, the rain detection device will first perform a self-check to ensure that all sensors are in normal working condition. Once the rain detection device enters the working state, it will start collecting rainfall data in real time. These data include key parameters such as the size, density, and falling speed of raindrops. After the sensor converts these parameters into electrical signals, they are amplified and processed to ultimately become rainfall information. This information is transmitted to the central processor in real time for subsequent calculation and analysis. To ensure the real-time and accuracy of the system, the rain detection device will continuously collect new rainfall data and update the information transmitted to the central processor. This means that the central processor can adjust the air jet speed and angle at any time based on the latest rainfall information to ensure that the air curtain can always cover the required rain-avoiding range. When detecting rainfall, ensure that the sensor surface of the rain detection device is clean and free of dirt to avoid affecting the detection accuracy. Regularly calibrate and maintain the rain detection device to ensure its long-term stable operation and accurate detection. In the case of large changes in rainfall, the system should be able to quickly respond and adjust the air jet speed and angle to maintain the stability and effectiveness of the air curtain.

[0066] Based on the first and / or second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as the above-mentioned first and second embodiments can be referred to the above introduction, and the following will not be repeated. On this basis, please refer to Figure 3 In this embodiment, step S20, the step of calculating the air jet speed and angle of the air jet nozzle of the vehicle-mounted air umbrella according to the current rainfall, further comprises:

[0067] Step S21, the vehicle-mounted air umbrella records the rainfall detection information;

[0068] Step S22, according to the rainfall detection information, the vehicle-mounted air umbrella calculates the angle between the air jet direction of the air jet nozzle and the horizontal plane and the air jet speed of the air jet nozzle.

[0069] Specifically, in this embodiment, by intelligently calculating and controlling the air jet speed and angle of the air jet nozzle, an effective rain-shielding air curtain is formed to protect the driver and passengers from being wet by rain when getting off the car in rainy days, and to prevent rainwater from entering the car. The following are the detailed steps and explanations:

[0070] Step S21: Detect whether it is raining and the amount of rain, and record the information of the current rainfall. In step S12, the system has obtained the current rainfall data through the rain detection device. In step S21, the system will again confirm whether it is raining and the specific amount of rain. This is to ensure the accuracy of the subsequent calculation process. After confirming the rainfall, the system will record the current rainfall information in detail. These records include the specific value of the rainfall, the detection time, etc. These information is of great significance for subsequent analysis of rain-shielding effect, optimization of air jet strategy, etc. When recording the rainfall information, ensure the accuracy and completeness of the data. If abnormal rainfall data is detected, please handle and analyze it in time to avoid affecting the subsequent air jet calculation process.

[0071] Step S22: According to the current rainfall, calculate the angle between the air jet direction of the air jet nozzle and the horizontal plane and the gas injection speed of the air jet nozzle. The angle between the air jet direction and the horizontal plane (i.e. the air jet angle) is one of the key factors affecting the effect of the rain-shielding air curtain. In step S22, the system will calculate the appropriate air jet angle according to the current rainfall size and the preset algorithm or model. Generally speaking, the larger the rainfall, the larger the air jet angle should be increased to ensure that the air curtain can cover a wider range of rain-shielding. At the same time, the calculation of the air jet angle will also take into account the height, shape of the vehicle and the installation position of the air jet nozzle, etc. The gas injection speed is another key factor affecting the strength and stability of the rain-shielding air curtain. In step S22, the system will further calculate the appropriate gas injection speed according to the current rainfall size and the calculation result of the air jet angle. Generally speaking, the larger the rainfall, the faster the gas injection speed should be increased to enhance the rain-shielding effect of the air curtain. At the same time, the calculation of the gas injection speed will also take into account the caliber of the air jet nozzle, the pressure and flow of the gas, etc.

[0072] When calculating the air jet angle and gas injection speed, the system will also optimize the air jet strategy based on historical records and analysis results. For example, if historical data shows that the existing air jet strategy is not effective in a certain rainfall range, the system can automatically adjust the air jet angle and gas injection speed to improve the rain-shielding effect. When calculating the air jet angle and gas injection speed, ensure that the algorithm or model used is accurate and reliable. If abnormal data or results occur during the calculation process, please check and analyze it in time to avoid affecting the subsequent air jet process. Regularly optimize and adjust the air jet strategy to adapt to changes in different weather conditions and vehicle conditions.

[0073] Based on the first embodiment and / or the second embodiment and / or the third embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as the above-mentioned embodiments one, embodiments two, embodiments three can refer to the above introduction, and the following will not be described. On this basis, please refer toFigure 4 In this embodiment, step S30, the vehicle-mounted air umbrella controls the air flow nozzle to form a rain-shielding air curtain by jetting air according to the jetting speed and angle, further includes:

[0074] Step S31, according to the rain amount detection information result, the vehicle-mounted air umbrella obtains the corresponding control instruction;

[0075] Step S32, according to the control instruction, the vehicle-mounted air umbrella adjusts the jetting angle of the air flow nozzle and the gas jetting speed of the air flow nozzle to block the raindrops.

[0076] Specifically, in this embodiment, it is crucial to provide a dry and comfortable environment for the passengers. The vehicle-mounted air umbrella intelligent adjustment system forms an effective rain-shielding air curtain by precisely controlling the jetting speed and angle of the air flow nozzle, protecting the passengers from getting wet when getting off the vehicle in the rain. The following steps will be described in detail to better understand the entire rain-shielding adjustment process.

[0077] Step S31: According to the rain amount information result, output the corresponding control instruction. In step S22, the system has calculated the jetting speed and angle of the air flow nozzle according to the current rain amount information. In step S31, the vehicle will first analyze these information in detail to determine the best jetting strategy. The analysis process includes considering the rain amount, raindrop density, vehicle speed, wind direction and other factors to ensure that the generated rain-shielding air curtain can fully cover the rain-shielding needs of the passengers. According to the analysis of the rain amount information result, the vehicle will generate corresponding control instructions. These instructions include the specific value of the jetting angle, the specific value of the gas jetting speed and the setting of the jetting duration, etc. These instructions are transmitted to the control unit of the air flow nozzle through the vehicle network to guide the subsequent jetting operation. After generating the control instructions, the vehicle will perform optimization and verification of the instructions. Optimization work mainly adjusts the instructions according to historical data and experience to improve the effect and stability of the rain-shielding air curtain. The verification work is to ensure the accuracy and reliability of the instructions to avoid poor jetting effect or system abnormalities due to instruction errors. When generating control instructions, please ensure comprehensive consideration to avoid affecting the rain-shielding effect due to missing important factors. Regularly optimize and adjust the control instructions to adapt to changes in different weather conditions and vehicle conditions. When verifying the instructions, please ensure the use of accurate verification methods and tools to avoid system abnormalities due to verification errors.

[0078] Step S32: Adjust the jet angle of the air jet nozzle and the gas injection speed of the air jet nozzle according to the control instruction to block the raindrops. The control instruction generated in step S31 is transmitted to the control unit of the air jet nozzle through the vehicle network. After receiving the instruction, the control unit will parse and confirm it to ensure its accuracy and integrity. According to the jet angle value in the control instruction, the control unit will drive the rotating mechanism of the air jet nozzle to adjust the jet angle to the specified position. During the adjustment process, the system will monitor the change of the jet angle in real time to ensure that the adjustment is in place and stable. At the same time, according to the gas injection speed value in the control instruction, the control unit will adjust the gas supply system of the air jet nozzle to change the pressure and flow of the gas, so as to achieve the specified injection speed. During the adjustment process, the system will monitor the change of the gas injection speed in real time to ensure that the adjustment is in place and stable.

[0079] After adjusting the jet angle and gas injection speed, the air jet nozzle will start to spray air to form a rain-shielding air curtain. At this time, the system will monitor the effect and stability of the rain-shielding air curtain in real time and make fine adjustments as needed. The fine adjustment process includes adjusting the jet angle and the gas injection speed slightly to ensure that the rain-shielding air curtain can fully cover the rain-shielding needs of the passengers, while avoiding unnecessary interference to the vehicle and the surrounding environment. When adjusting the air jet nozzle, make sure to operate smoothly and slowly to avoid damaging the equipment or failing to adjust to the right position. After forming the rain-shielding air curtain, continuously monitor its effect and stability and make fine adjustments in time to ensure the best rain-shielding effect. During use, regularly check the working status of the air jet nozzle and the control unit to ensure their normal operation and timely maintenance.

[0080] Further, in the embodiment, the step of obtaining the corresponding control instruction according to the rain amount detection information result further comprises:

[0081] When the rain amount information is at a rain amount value in a first preset interval, the vehicle-mounted air parachute obtains a corresponding closing instruction;

[0082] When the rain amount information is at a rain amount value in a second preset interval, the vehicle-mounted air parachute obtains a corresponding opening instruction.

[0083] Specifically, in the embodiment, the jet speed and jet angle of the air jet nozzle are intelligently adjusted according to the rain amount information to form an effective rain-shielding air curtain and provide a comfortable rain-shielding environment for passengers. However, in actual application, the size of the rain amount directly affects the demand and effect of the rain-shielding air curtain. Therefore, the system needs to be able to intelligently output control instructions to close or open the vehicle-mounted air parachute according to the rain amount information. The following will describe this process in detail, including the judgment of rain amount information, the generation and output of control instructions, etc.

[0084] The collected rainfall information is transmitted to the vehicle system through the vehicle network for subsequent processing and judgment. The vehicle system has two preset rainfall intervals, i.e., a first preset interval and a second preset interval. The two intervals correspond to the rainfall thresholds for closing and opening the vehicle air umbrella, respectively. After receiving the rainfall information, the vehicle system immediately determines the interval in which the current rainfall information is located.

[0085] When the rainfall information is in the first preset interval, it indicates that the current rainfall is small and the rain-shielding air curtain does not need to be opened. The vehicle system generates a control instruction to close the vehicle air umbrella according to the judgment result. The control instruction is transmitted to the control unit of the air jet nozzle through the vehicle network, and the vehicle system also informs the driver and passenger of the current state through the display screen or voice prompt. After receiving the closing instruction, the control unit of the air jet nozzle immediately stops the air jet and closes the vehicle air umbrella.

[0086] When the rainfall information is in the second preset interval, it indicates that the current rainfall is large and the rain-shielding air curtain needs to be opened to provide rain protection. The vehicle system generates a control instruction to open the vehicle air umbrella according to the judgment result. At the same time, the optimal jet speed and jet angle are calculated according to the rainfall information. The control instruction and jet parameters are transmitted to the control unit of the air jet nozzle through the vehicle network. After receiving the opening instruction and jet parameters, the control unit of the air jet nozzle immediately adjusts the jet angle and jet speed to form an effective rain-shielding air curtain. At the same time, the vehicle system also informs the driver and passenger of the current state through the display screen or voice prompt. The vehicle system analyzes and mines the data according to the historical rainfall information and the execution effect of the control instruction. According to the analysis result, the vehicle system adjusts and optimizes the generation strategy of the control instruction to improve the effect and stability of the rain-shielding air curtain. The vehicle system has a verification mechanism to verify the accuracy and integrity of the control instruction. When the verification finds that the instruction is abnormal, the vehicle system immediately performs abnormal processing, including re-generating the instruction, alarming, etc.

[0087] When using the intelligent adjustment system of the vehicle air umbrella, please ensure that the rainfall sensor is in normal working condition to avoid misjudgment due to sensor failure. When the system executes the closing or opening instruction, please ensure that the air jet nozzle and its control unit are in normal working condition to avoid affecting the execution of the instruction due to equipment failure. Please regularly check the software and hardware status of the vehicle system and its related components to ensure their normal operation and timely maintenance. Regularly clean and calibrate the rainfall sensor to ensure the accuracy of the collected data. Regularly maintain and maintain the air jet nozzle and its control unit, including cleaning the nozzle blockage, checking the circuit connection, etc.

[0088] Further, in the present embodiment, when the rainfall information is in the second preset interval, the vehicle air umbrella obtains a corresponding opening instruction, which further includes:

[0089] obtaining an instruction to control the air jet angle of the air jet nozzle to be adjusted to a larger angle and to increase the gas injection speed of the air jet nozzle when the rainfall information is detected to increase;

[0090] obtaining an instruction to control the air jet angle of the air jet nozzle to be adjusted to a smaller angle and to decrease the gas injection speed of the air jet nozzle when the rainfall information is detected to decrease.

[0091] Specifically, in the present embodiment, the vehicle-mounted air umbrella intelligent adjustment system can not only intelligently turn on or off the rain-shielding air curtain according to the rainfall information, but also dynamically adjust the air jet angle and the gas injection speed of the air jet nozzle according to the real-time changes of the rainfall, so as to ensure that the rain-shielding air curtain is always in the best state and provide stable and efficient rain protection for the driver and passengers. In the present embodiment, the following are the detailed steps and explanations:

[0092] The vehicle-mounted air umbrella intelligent adjustment system is equipped with a high-precision rainfall sensor, which can collect the rainfall information of the current environment in real time. The collected rainfall information is transmitted to the vehicle infotainment system in real time through the vehicle network and processed and analyzed by the vehicle infotainment system. The vehicle infotainment system monitors the received rainfall information in real time, compares the current rainfall information with the rainfall information at the last time, and judges whether the rainfall has changed. When the rainfall information is detected to increase, it indicates that the current rainfall is increasing and the effect of the rain-shielding air curtain needs to be enhanced; when the rainfall information is detected to decrease, it indicates that the current rainfall is decreasing and the effect of the rain-shielding air curtain can be appropriately weakened. According to the rainfall change detection result, the vehicle infotainment system will generate a control instruction for adjusting the air jet angle of the air jet nozzle. When the rainfall increases, the control instruction will instruct the air jet nozzle to adjust the air jet angle to a larger angle to expand the coverage range of the rain-shielding air curtain; when the rainfall decreases, the control instruction will instruct the air jet nozzle to adjust the air jet angle to a smaller angle to reduce the coverage range of the rain-shielding air curtain. At the same time, the vehicle infotainment system will also generate a control instruction for adjusting the gas injection speed of the air jet nozzle. When the rainfall increases, the control instruction will instruct the air jet nozzle to increase the gas injection speed to enhance the strength and stability of the rain-shielding air curtain; when the rainfall decreases, the control instruction will instruct the air jet nozzle to decrease the gas injection speed to reduce energy consumption and noise. The generated control instruction is transmitted to the control unit of the air jet nozzle in real time through the vehicle network. After receiving the control instruction, the control unit will perform instruction confirmation and analysis to ensure the accuracy and integrity of the instruction. According to the received control instruction, the control unit of the air jet nozzle drives the rotating mechanism of the nozzle to adjust the air jet angle. During the adjustment process, the system will monitor the change of the air jet angle in real time to ensure that the adjustment is in place and stable.

[0093] After the adjustment is completed, the control unit will feed back the actual value of the air jet angle to the car system, so that the car system can verify and record the adjustment effect. At the same time, the control unit of the air jet nozzle will also adjust the pressure and flow of the gas supply system according to the received control instructions, so as to change the gas injection speed. During the adjustment process, the system will monitor the change of the gas injection speed in real time to ensure that the adjustment is in place and stable. After the adjustment is completed, the control unit will feed back the actual value of the gas injection speed to the car system, so that the car system can verify and record the adjustment effect. The car system will monitor the air jet angle of the air jet nozzle, the gas injection speed and the effect of the rain shielding air curtain in real time. When the system state is abnormal, such as the air jet angle adjustment is not in place, the gas injection speed is not stable, etc., the car system will immediately perform abnormal detection and diagnosis. When the abnormality is detected, the car system will immediately issue an alarm prompt to inform the driver and passenger that the current system state is abnormal. At the same time, the car system will also troubleshoot to try to locate and repair the abnormal cause. If it cannot be repaired, the system will suggest that the driver and passenger send the vehicle to a professional repair shop for repair. When using the intelligent adjustment system of the vehicle-mounted air umbrella, please ensure that the rain sensor and the air jet nozzle are in normal working condition to avoid affecting the system performance due to equipment failure. When the system executes the dynamic adjustment instruction, ensure that the vehicle is in a stable driving state to avoid affecting the accuracy of the air jet angle and the gas injection speed due to the vehicle bumping.
