Description

Technical Field

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

[0002] With the explosive popularity of the connected car industry, user experience has become a key factor in car purchase decisions. On rainy days, car drivers and passengers need to close or open umbrellas at the door when entering or exiting the vehicle. In the process, people are easily wet, and raindrops will also float into the car, causing a bad experience. The airflow nozzle of the existing vehicle-mounted air umbrella device is usually installed on the top of the door. This design will blow rain into the car when the airflow spray angle is small or the jet speed is small. This is because when the airflow is sprayed at a small angle or speed, it cannot form an effective air curtain to block the rain. Instead, it may blow the rain away and bring it into the car, causing discomfort to the driver and passengers and wetness in the car. As the door is opened and closed, the rain shelter range of the air umbrella will change accordingly. This is because the position and spray direction of the airflow nozzle are fixed, and when the door is opened, the distance between the airflow nozzle on the top of the door and the driver and passenger will change, causing the coverage of the air curtain to change accordingly. This change may cause the driver and passenger to still be wetted by rain when entering and exiting the vehicle, thereby reducing the practicality of the air umbrella. Existing on-vehicle air umbrella devices usually lack an intelligent adjustment system and cannot automatically adjust the jet intensity, angle and duration of the airflow nozzle according to external environmental factors such as rain intensity, wind direction, and vehicle speed. This results in the air umbrella being unable to provide the best rain shelter effect when facing different weather conditions. For example, in heavy rain, if the jet intensity of the airflow nozzle is not strong enough, an effective air curtain cannot be formed to block the rain; in light rain, if the jet intensity is too high, it may cause unnecessary energy consumption and noise. Due to the lack of an intelligent adjustment system, existing on-vehicle air umbrella devices usually require manual operation by the driver and passengers to open or close. This manual operation is not only cumbersome, but may also increase the difficulty and inconvenience of operation in rainy environments. In addition, manual operation may also lead to operational errors or omissions, thereby reducing the reliability and practicality of the air umbrella.

[0003] Existing on-board air umbrella devices are usually disconnected from the vehicle's intelligent system and cannot be seamlessly connected with other intelligent functions of the vehicle (such as navigation, entertainment, driving assistance, etc.). This results in the air umbrella being unable to match the overall intelligence 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, existing on-board air umbrella devices usually lack these environmental perception capabilities and cannot automatically adjust the working state of the airflow nozzle according to real-time data. This results in the air umbrella being unable to provide the best rain shelter when facing complex and changeable weather conditions. Summary of the invention

You can also manually adjust and execute relevant commands on the vehicle computer and mobile phone APP to start and close the air umbrella, adjust the angle of the air umbrella and the rain shelter range to meet the needs of different scenarios in different regions.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this 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 present application provides a vehicle-mounted air umbrella adjustment system, which aims to form an effective rain-shielding air curtain by precisely controlling the jet speed and angle of the airflow nozzle to protect the driver and passengers from getting wet when getting out of the car on a rainy day, and prevent rain from entering the car. The system integrates the vehicle-mounted system and the mobile phone APP system, both of which have the same functions, and the user can operate in either way.

[0045] The user clicks the "Air Umbrella" button on the operation page of the vehicle computer or mobile phone APP to start the air umbrella function. If started through the vehicle computer, it will directly enter the air umbrella start step; if started through the mobile phone APP, the APP will send an MQTT message to the vehicle computer TBOX. After TBOX receives the message, it will enter the air umbrella start step. The vehicle computer starts the function of the on-board air umbrella processor module through the CAN signal. The vehicle computer starts the rain detection device to detect whether it is raining and the amount of rain, and passes the rainfall information to the central processor. The central processor calculates the angle A between the airflow nozzle jet and the horizontal plane and the jet speed V based on the rainfall information. The calculation formula is as follows:

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

[0047] Where h is the height difference between the airflow nozzle and the ground (meters), and E1 is the correction coefficient (0.9~1.3, default is 1). Jet speed V=E2*(2+0.6*S), where S is the rainfall (grams per square centimeter per second), and E2 is the correction coefficient (0.8~1.2, adjusted according to temperature and altitude, default is 1). The air umbrella function is running, and the airflow nozzle starts to spray to form a rain-proof air curtain. If it is turned off through the car computer, it will directly enter the step of closing the air umbrella; if it is turned off through the mobile phone APP, the APP will send an MQTT message to the car computer TBOX, and after TBOX receives the message, it will enter the step of closing the air umbrella. The car computer turns off the function of the on-board air umbrella processor module through the CAN signal. The airflow nozzle stops spraying.

[0048] The user clicks the "Adjust Umbrella Angle" button on the operation page of the vehicle computer or mobile phone APP to start adjusting the angle of the air umbrella. The on-board air umbrella processor receives the angle information and evokes the airflow nozzle angle adjustment function. The processor adjusts the elevation angle between the airflow nozzle and the horizontal plane based on the angle information. The user clicks the "Adjust Umbrella Angle" button on the operation page of the vehicle computer or mobile phone APP (Note: the button name here may need to be changed to a more clear "Adjust Rain Shelter Range" button to avoid confusion). The user chooses to increase or decrease the range. If adjusted through the mobile phone APP, the APP sends an MQTT message to the vehicle computer TBOX. After TBOX receives the message, the on-board air umbrella processor receives the range information and evokes the airflow nozzle speed adjustment function. The processor adjusts the jet speed based on the range information. If the range needs to be increased, the jet speed is increased; if the range needs to be reduced, the jet speed is reduced. Since it is impossible to directly display the flowchart, the corresponding flowchart can be drawn based on the above description. The flowchart of each function should include the starting point, each operation step, the decision point (such as choosing to increase / decrease the angle or range), the execution action (such as sending a message, starting / stopping the processor, adjusting the angle / speed), and the end point. The flow chart should be clear and easy for users to understand and operate. In actual operation, users need to ensure that the connection between the vehicle computer and the mobile phone APP is normal to ensure the accurate transmission and execution of instructions. The settings of the correction coefficients E1 and E2 need to be adjusted according to the actual situation to achieve the best rain-shielding effect. When adjusting the angle of the air umbrella and the rain-shielding range, users should pay attention to observe the adjustment results and make timely adjustments as needed to ensure the effectiveness and stability of the rain-shielding air curtain.

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

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

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

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

[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 getting wet when getting out of the car on a rainy day, while preventing rain from entering the car. This method combines the rain detection device, the central processor, and the precise control of the airflow nozzle to achieve intelligent air umbrella adjustment. The following is a detailed description of the above steps:

[0054] Step S10: Detect the current rainfall using a rain detection device. The rain detection device is one of the core components of the vehicle-mounted air umbrella adjustment system. Its main function is to monitor the rainfall in the external environment in real time. The device usually uses advanced sensor technology to accurately sense parameters such as the size, density and falling speed of raindrops, and then calculate the current rainfall. The working principle of the rain detection device is based on sensor technologies such as optics, capacitance or piezoelectricity. Taking an optical sensor as an example, when raindrops fall on the surface of the sensor, they change the propagation path or reflection intensity of the light, thereby triggering the circuit inside the sensor to generate an electrical signal. After amplification and processing, this electrical signal can be converted into rainfall information. Once the rain detection device detects the 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 the subsequent calculation of the jet speed and jet angle. When using the rain detection device, ensure that its surface 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.

[0055] Step S20: Calculate the jet speed and jet angle of the airflow nozzle according to the current rainfall. The central processing unit is another core component of the vehicle-mounted air umbrella adjustment system. It is responsible for receiving the rainfall information transmitted by the rain detection device and calculating the appropriate airflow nozzle jet speed and jet angle according to the preset algorithm or model. When calculating the jet speed and jet angle, the central processing unit will comprehensively consider multiple factors, including the amount of rainfall, the height difference between the airflow nozzle and the ground, the correction coefficient, etc. Usually, 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 is also 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 airflow nozzle and the ground and the correction coefficient E1. Generally speaking, the greater the height difference h, the smaller the jet angle A; and vice versa. 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 shelter 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 a correction coefficient. When calculating the jet velocity and jet angle, the algorithm or model used should be accurate and reliable to avoid excessive errors. The correction coefficients E1 and E2 should be adjusted according to the actual situation to achieve the best rain shielding effect.

[0058] Step S30: Control the airflow nozzle to form a rain-shielding air curtain by jetting according to the jet speed and jet angle to avoid rain. The airflow nozzle is the actuator of the vehicle-mounted air umbrella adjustment system. It is responsible for converting high-pressure gas into high-speed airflow and forming a rain-shielding air curtain through a specific jet speed and jet angle. The airflow nozzle is usually composed of a nozzle body, an airflow channel, and an adjustment mechanism. After calculating the appropriate jet speed and jet angle in step S20, the central processing unit will pass these parameters to the adjustment mechanism of the airflow nozzle through a control signal. After receiving the control signal, the adjustment mechanism will immediately adjust the jet speed and jet angle of the airflow nozzle to ensure that the air curtain can be formed according to the preset requirements. When the airflow nozzle jets according to the calculated jet speed and jet angle, a continuous air curtain will be formed around the vehicle. This air curtain has a certain thickness and strength, which can effectively block the invasion of raindrops. At the same time, since the air curtain is dynamic, it can be adaptively adjusted according to the change in rainfall to ensure the stability and reliability of the rain-shielding effect.

[0059] It is particularly important to note that when controlling the airflow nozzle to spray, the gas pressure and flow rate should be stable and reliable to avoid affecting the formation effect of the air curtain. The airflow nozzle should be cleaned and maintained regularly to ensure that its internal passage is unobstructed to avoid affecting the spray effect due to blockage.

[0060] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 In this embodiment, the step of detecting the current rainfall amount by the vehicle-mounted air umbrella through the rain detection device also includes:

[0061] Step S11, the vehicle-mounted air umbrella starts the jet-jet rain shelter function by acquiring button information on the function page;

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

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

[0064] Step S11: Start the jet rain shelter function through the button on the function page. The function page is an important part of the user interface of the vehicle-mounted air umbrella adjustment system, which provides users with an intuitive and easy-to-use operation interface. On this page, users can easily find and operate the start button of the jet rain shelter function. The start button of the jet rain shelter function is usually designed as a striking 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 jet rain shelter function, the user first enters the function page through the main interface or quick entry of the vehicle-mounted system. On the function page, the user needs to find the start button of the jet rain shelter 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 jet rain shelter function. When the user clicks the start button, the vehicle-mounted system will immediately generate a start signal and transmit the signal to the central processor. After receiving the start signal, the central processor will immediately enter the standby state, ready to receive the rainfall information transmitted by the rain detection device, and calculate the jet speed and jet angle based on this information. When designing a function page, ensure that the button style and position are consistent with user habits to improve operational efficiency and user experience. After the user clicks the start button, the system should provide clear feedback (such as a pop-up prompt box or a change in button color, etc.) to confirm that the function has been successfully started.

[0065] Step S12: After receiving the start signal, the rain detection device performs rainfall detection. In step S11, the user starts the jet rain shelter 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 the standby state and prepare to receive the rainfall information transmitted by the rain detection device. After receiving the start signal, the rain detection device will immediately enter the working state. This means that the sensor will start to monitor the rainfall in the external environment in real time and transmit the monitored data to the central processor. In order to ensure the accuracy of the detection, the rain detection device will first perform a self-test to ensure that all sensors are in normal working condition. Once the rain detection device enters the working state, it will start to collect 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 and finally converted into rainfall information. This information will be transmitted to the central processor in real time for subsequent calculation and analysis. In order 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 jet speed and jet angle at any time according to the latest rainfall information to ensure that the air curtain can always cover the required rain shelter range. When performing rainfall detection, the sensor surface of the rain detection device should be clean and free of dirt to avoid affecting the detection accuracy. The rain detection device should be calibrated and maintained regularly to ensure its long-term stable operation and accurate detection. In the case of large changes in rainfall, the system should be able to respond quickly and adjust the jet speed and jet angle to maintain the stability and effectiveness of the air curtain.

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

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

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

[0069] Specifically, in this embodiment, by intelligently calculating and 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 getting wet when getting out of the car on rainy days, and to prevent rain from entering the car. The following are detailed steps and instructions:

[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 confirm again 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. This information is of great significance for the subsequent analysis of the rain shelter effect, the optimization of the jet strategy, etc. When recording rainfall information, please ensure the accuracy and completeness of the data. If abnormal rainfall data is detected, please process and analyze it in time to avoid affecting the subsequent jet calculation process.

[0071] Step S22: According to the current rainfall, calculate the angle between the jet direction of the airflow nozzle and the horizontal plane and the gas jet speed of the airflow nozzle. The angle between the jet direction and the horizontal plane (i.e., the 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 jet angle according to the current rainfall amount, combined with a preset algorithm or model. Generally speaking, the greater the rainfall, the jet angle should be appropriately increased to ensure that the air curtain can cover a wider range of rain shelter. At the same time, the calculation of the jet angle will also take into account factors such as the height and shape of the vehicle and the installation position of the airflow nozzle. The gas jet 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 jet speed based on the current rainfall amount and the calculation results of the jet angle. Generally speaking, the greater the rainfall, the gas jet speed should be appropriately accelerated to enhance the rain-shielding effect of the air curtain. At the same time, the calculation of the gas jet speed will also take into account factors such as the caliber of the airflow nozzle, the pressure and flow rate of the gas.

[0072] When calculating the jet angle and gas jet speed, the system will also optimize the jet strategy based on historical records and analysis results. For example, if historical data shows that the existing jet strategy is not effective within a certain rainfall range, the system can automatically adjust the jet angle and gas jet speed to improve the rain shelter effect. When calculating the jet angle and gas jet speed, please ensure that the algorithm or model used is accurate and reliable. If abnormal data or results appear during the calculation process, please check and analyze them in time to avoid affecting the subsequent jet process. Regularly optimize and adjust the jet strategy to adapt to different weather conditions and changes in 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 those of the above-mentioned first embodiment, second embodiment and third embodiment can refer to the above introduction and will not be repeated later. Figure 4 In this embodiment, step S30, the vehicle-mounted air umbrella controls the airflow nozzle to form a rain-shielding air curtain by jetting air according to the jet speed and jet angle to avoid rain, further includes:

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

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

[0076] Specifically, in this embodiment, it is very important to provide a dry and comfortable environment for the driver and passengers. The vehicle-mounted air umbrella intelligent adjustment system forms an effective rain-proof air curtain by accurately controlling the jet speed and jet angle of the airflow nozzle to protect the driver and passengers from getting wet when getting off the car in rainy days. The following will describe the steps in detail to better understand the entire rain-proof adjustment process.

[0077] Step S31: Output the corresponding control instructions according to the rainfall information results. In step S22, the system has calculated the jet speed and jet angle of the airflow nozzle according to the current rainfall information. In step S31, the vehicle will first analyze this information in detail to determine the best jet strategy. The analysis process includes considering multiple factors such as rainfall, raindrop density, vehicle speed, wind direction, etc. to ensure that the generated rain-shielding air curtain can fully cover the rain shelter needs of the driver and passengers. According to the analysis of the rainfall information results, the vehicle will generate corresponding control instructions. These instructions include the specific value of the jet angle, the specific value of the gas jet speed, and the setting of the jet duration. These instructions are transmitted to the control unit of the airflow nozzle through the vehicle network to guide the subsequent jet operation. After generating the control instructions, the vehicle will optimize and verify the instructions. The optimization work is mainly to fine-tune the instructions based on 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 jet effect or system abnormality due to instruction errors. When generating control instructions, please make sure to consider them comprehensively to avoid affecting the rain shelter effect due to the omission of important factors. Regularly optimize and adjust control commands to adapt to different weather conditions and vehicle conditions. When verifying commands, make sure to use accurate verification methods and tools to avoid system abnormalities due to verification errors.

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

[0079] After adjusting the jet angle and gas jet speed, the airflow nozzle will start to spray 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-tuning process includes adjusting the jet angle and slight changes in the gas jet speed to ensure that the rain-shielding air curtain can fully cover the rain-shielding needs of the driver and passengers while avoiding unnecessary interference to the vehicle and the surrounding environment. When adjusting the airflow nozzle, please ensure smooth and slow operation to avoid damage to the equipment or inadequate adjustment due to excessive operation. After the rain-shielding air curtain is formed, please continue to pay attention to its effect and stability, and make fine adjustments in time to ensure the best rain-shielding effect. During use, please regularly check the working status of the airflow nozzle and control unit to ensure their normal operation and timely maintenance.

[0080] Further, in this embodiment, the step of the vehicle-mounted air umbrella acquiring corresponding control instructions according to the rainfall detection information result further includes:

[0081] When the rainfall information is at a rainfall value within a first preset interval, the vehicle-mounted air umbrella obtains a corresponding closing instruction;

[0082] When the rainfall information is at a rainfall value within a second preset interval, the vehicle-mounted air umbrella obtains a corresponding opening instruction.

[0083] Specifically, in this embodiment, the jet speed and jet angle of the airflow nozzle are intelligently adjusted according to the rainfall information to form an effective rain-shielding air curtain, providing a comfortable rain-proof environment for the driver and passengers. However, in actual applications, the amount of rainfall directly affects the demand and effect of the rain-shielding air curtain. Therefore, the system needs to be able to intelligently output control instructions for closing or opening the vehicle-mounted air umbrella according to the rainfall information. This process will be described in detail below, including the steps of judging the rainfall information, generating and outputting the control instructions, etc.

[0084] The collected rainfall information is transmitted to the vehicle computer system through the vehicle network for subsequent processing and judgment. Two rainfall intervals are preset in the vehicle computer system, namely the first preset interval and the second preset interval. These two intervals correspond to the rainfall thresholds for closing and opening the vehicle air umbrella respectively. After receiving the rainfall information, the vehicle computer system will immediately make an interval judgment to determine 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 there is no need to open the rain-shielding air curtain. The vehicle system generates a control command to close the vehicle air umbrella based on the judgment result. The control command is transmitted to the control unit of the airflow nozzle through the vehicle network. At the same time, the vehicle system will also inform the driver and passengers of the current status through the display screen or voice prompts. After receiving the closing command, the control unit of the airflow nozzle will immediately stop spraying and close 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 command to open the vehicle air umbrella based on the judgment result. At the same time, the optimal jet speed and jet angle are calculated based on the rainfall information. The control command and jet parameters are transmitted to the control unit of the airflow nozzle through the vehicle network. After receiving the opening command and jet parameters, the control unit of the airflow nozzle will immediately adjust the jet angle and jet speed to form an effective rain-shielding air curtain. At the same time, the vehicle system will also inform the driver and passengers of the current status through display screens or voice prompts. The vehicle system will perform data analysis and mining based on historical rainfall information and the execution effect of control commands. According to the analysis results, the vehicle system will adjust and optimize the generation strategy of control commands to improve the effect and stability of the rain-shielding air curtain. The vehicle system is equipped with a verification mechanism to verify the accuracy and integrity of the control command. When the verification finds that the command is abnormal, the vehicle system will immediately handle the exception, including regenerating the command, alarming, etc.

[0087] When using the vehicle-mounted air umbrella intelligent adjustment system, please ensure that the rain sensor is in normal working condition to avoid misjudgment due to sensor failure. When the system executes a shutdown or opening command, please ensure that the airflow nozzle and its control unit are in normal working condition to avoid affecting the execution of the command 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. Clean and calibrate the rain sensor regularly to ensure the accuracy of the data it collects. Regularly maintain and service the airflow nozzle and its control unit, including cleaning the nozzle blockage and checking the circuit connection.

[0088] Further, in this embodiment, when the rainfall information is in a rainfall value within a second preset interval, the step of the vehicle-mounted air umbrella acquiring a corresponding opening instruction further includes:

[0089] When the rainfall information is detected to increase, an instruction is obtained to control the jet angle of the airflow nozzle to be adjusted to a larger angle and to increase the gas jet speed of the airflow nozzle;

[0090] When it is detected that the rainfall information is decreasing, an instruction is obtained to control the jet angle of the airflow nozzle to be adjusted to a smaller angle and to reduce the gas jet speed of the airflow nozzle.

[0091] Specifically, in this embodiment, the vehicle-mounted air umbrella intelligent adjustment system can not only intelligently open or close the rain-shielding air curtain according to the rainfall information, but also dynamically adjust the jet angle and gas jet speed of the airflow nozzle according to the real-time change of rainfall, so as to ensure that the rain-shielding air curtain is always kept in the best state, providing stable and efficient rain protection for the driver and passengers. In this embodiment, the following are the detailed steps and instructions:

[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 system in real time through the vehicle network, and is processed and analyzed by the vehicle system. The vehicle system monitors the received rainfall information in real time, and judges whether the rainfall has changed by comparing the current rainfall information with the rainfall information at the previous moment. 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 system will generate a control instruction to control the adjustment of the jet angle of the airflow nozzle. When the rainfall increases, the control instruction will instruct the airflow nozzle to adjust the jet angle to a larger angle to expand the coverage of the rain-shielding air curtain; when the rainfall decreases, the control instruction will instruct the airflow nozzle to adjust the jet angle to a smaller angle to reduce the coverage of the rain-shielding air curtain. At the same time, the vehicle system will also generate a control instruction to control the adjustment of the gas injection speed of the airflow nozzle. When the rainfall increases, the control command will instruct the airflow nozzle to increase the gas injection speed to enhance the strength and stability of the rain-proof air curtain; when the rainfall decreases, the control command will instruct the airflow nozzle to reduce the gas injection speed to reduce energy consumption and noise. The generated control command is transmitted to the control unit of the airflow nozzle in real time through the vehicle network. After receiving the control command, the control unit will confirm and analyze the command to ensure the accuracy and completeness of the command. The control unit of the airflow nozzle drives the rotating mechanism of the nozzle to adjust the jet angle according to the received control command. During the adjustment process, the system will monitor the changes in the 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 jet angle to the vehicle system so that the vehicle system can verify and record the adjustment effect. At the same time, the control unit of the airflow nozzle will also adjust the pressure and flow of the gas supply system according to the control instructions received, thereby changing the gas injection speed. During the adjustment process, the system will monitor the changes in 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 vehicle system so that the vehicle system can verify and record the adjustment effect. The vehicle system will monitor the jet angle of the airflow nozzle, the gas injection speed, and the effect of the rain-proof air curtain in real time. When the system status is abnormal, such as the jet angle is not adjusted in place, the gas injection speed is unstable, etc., the vehicle system will immediately perform abnormal detection and diagnosis. When an abnormality is detected, the vehicle system will immediately issue an alarm prompt to inform the driver and passengers that the current system status is abnormal. At the same time, the vehicle system will also perform troubleshooting to try to locate and repair the cause of the abnormality. If it cannot be repaired, the system will recommend that the driver and passengers send the vehicle to a professional repair shop for inspection. When using the vehicle-mounted air umbrella intelligent adjustment system, please ensure that the rain sensor and airflow nozzle are in normal working condition to avoid affecting the system performance due to equipment failure. When the system executes dynamic adjustment instructions, ensure that the vehicle is in a stable driving state to avoid affecting the accuracy of the jet angle and gas jet speed due to vehicle bumps.
