[0047] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0048] Figure 1 This is a flow chart of the vehicle intelligent rain protection method provided by the embodiment of the present application. Figure 1The present invention provides an intelligent vehicle rain protection method, which is applied to a vehicle. The vehicle includes an external camera, a rain sensor, a door status detection module, a window status detection module, a fan system, and an air outlet located above the door frame. The method can be implemented by an electronic device, such as an intelligent rain protection system. The following description uses the intelligent rain protection system as an example.

[0049] The intelligent rain protection system can be composed of a rain sensor, the vehicle's external cameras, a control system, a door and window status detection module, a fan system, and air outlets. It can accurately identify the vehicle's external environment and determine whether it is currently raining or washing. During rainfall, if the doors or windows are open, the intelligent rain protection system will automatically activate the rain protection function, blowing air through the air outlets above the door frame at a volume that matches the current rainfall, forming a rain barrier, effectively preventing rain from getting wet or entering the vehicle.

[0050] Vehicle intelligent rain protection methods can include:

[0051] Step 110: Determine the current state of the vehicle based on the detection data of the vehicle's external camera and the detection data of the rain sensor; the current state includes the car wash state and the rain state;

[0052] Step 120: When the current state is a rainy state, determine the amount of rainfall based on the detection data of the rain sensor, determine the degree of door opening based on the detection data of the door state detection module, and determine the degree of window opening based on the detection data of the window state detection module;

[0053] Step 130: Based on the amount of rainfall, the degree of door opening, and the degree of window opening, determine the air volume blown out obliquely from the air outlet by the fan system to form a rainproof barrier.

[0054] Specifically, the rain sensor in the intelligent rain protection system is used to monitor rainfall in real time and provide accurate detection data for the control system. The external camera is used to identify the current scene and distinguish between the rainfall state and the car wash state. The control system is used to make judgments and decisions based on the detection data of the external camera and the detection data of the rain sensor, and control the operation of the fan system and the air volume of the air outlet. The door status detection module is used to detect whether the door is in the open state and the degree of opening of the door. The window status detection module is used to detect whether the window is in the open state and the degree of opening of the window. The fan system is responsible for generating air volume and blowing it out through the air outlet to form a rain barrier. The air outlet is located above the door frame and blows air out obliquely to form an effective rain barrier.

[0055] In step 110, the intelligent rain protection system can determine the vehicle's current state based on data from the vehicle's external cameras and the rain sensor. The current state includes a car wash state and a rain state. By excluding the vehicle's car wash state, the intelligent rain protection system can prevent rain protection measures from being taken when the vehicle is in the car wash state.

[0056] In step 120, the intelligent rain protection system takes rain protection measures only when it determines that the vehicle is currently experiencing rainfall. The intelligent rain protection system can determine the amount of rainfall based on data from the rain sensor, the degree of door opening based on data from the door status detection module, and the degree of window opening based on data from the window status detection module.

[0057] The intelligent rain protection system uses rain sensors to monitor rainfall in real time and obtain detection data. Rain sensors typically use photoelectric or piezoelectric sensing to accurately sense the size, number, and velocity of raindrops, thereby calculating rainfall. Based on the detection data from the rain sensors, the intelligent rain protection system can classify rainfall into different levels, such as light rain, moderate rain, and heavy rain, or even more detailed levels, which can be intelligently learned and adjusted. Each level corresponds to different rain protection requirements. For example, light rain may only require light rain protection, while heavy rain requires more stringent rain protection measures.

[0058] The intelligent rain protection system will detect the degree of opening of the doors and windows in real time. According to the degree of opening of the doors and windows, the intelligent rain protection system will adjust the intensity of the rain protection measures. For example, when the doors or windows are fully open, stronger rain protection measures are required; when the doors or windows are partially open, the intensity of the rain protection measures can be appropriately weakened.

[0059] In step 130, the intelligent rain protection system can determine the air output of the fan system based on the amount of rainfall, the degree of door and window opening, and the degree of window opening. The air output of the fan system is blown out diagonally through the air outlet above the door frame, forming a rain barrier. The air output of the fan system can be adjusted by adjusting the fan speed. The fan system is designed with safety factors such as overheating protection and overload protection into consideration. During long-term operation or abnormal conditions, the intelligent rain protection system can automatically shut down the fan system to prevent damage or safety issues.

[0060] Specifically, when the rainfall level is light, if the door or window is not fully open, the Smart Rainscreen system will determine the airflow based on the degree of opening. Generally speaking, the airflow can be lower during light rain, as light rain is less intrusive to the vehicle interior. If the door or window is partially open, the Smart Rainscreen system may select a lower airflow to avoid unnecessary energy consumption and noise. If the door or window is fully open, the Smart Rainscreen system will increase the airflow appropriately to ensure effective rain protection.

[0061] In moderate rain, the airflow is generally higher than in light rain to cope with the heavier rain. If the door or window is partially open, the Intelligent Rainscreen system selects a moderate airflow to strike a balance between rain protection and energy consumption. If the door or window is fully open, the Intelligent Rainscreen system significantly increases the airflow to ensure the interior is not soaked by the rain.

[0062] When the rainfall is classified as heavy, the Smart Rain Protection system must ensure maximum protection. Therefore, as long as the doors and windows are not fully open, the Smart Rain Protection system will select the maximum air flow to respond. It should be noted that in heavy rain, even when the doors and windows are fully open, the Smart Rain Protection system may activate the fan system, blowing an appropriate amount of air through the air outlet to prevent rain from entering the vehicle through gaps.

[0063] The vehicle intelligent rain protection method provided in the embodiment of the present application determines the air output of the fan system by judging the current state of the vehicle and, when the current state is a raining state, based on the amount of rainfall, the degree of door opening and the degree of window opening, thereby forming a rainproof barrier. The method can accurately determine the size of the rainproof barrier, has a high level of intelligence, and has a good rainproof effect, and can effectively prevent damage to the vehicle caused by rainfall and inconvenience to passengers.

[0064] In one embodiment, the air volume blown out obliquely from the air outlet by the fan system is determined based on the amount of rainfall, the degree of door opening, and the degree of window opening, including: determining an index of the amount of rainfall; and determining a door opening coefficient based on the degree of door opening; and determining a window opening coefficient based on the degree of window opening; and determining a weight factor of the window opening; and determining the air volume based on a preset adjustment coefficient, the amount of rainfall, the index, the door opening coefficient, the window opening coefficient, and the weight factor.

[0065] Generally speaking, the greater the rainfall, the wider the car doors and windows are open, and the greater the air output of the fan system.

[0066] The vehicle intelligent rain protection method provided in the embodiment of the present application determines the air output of the fan system based on the amount of rainfall, the degree of door opening and the degree of window opening, thereby forming a rainproof barrier. It can accurately determine the size of the rainproof barrier, has a high level of intelligence, and has a good rainproof effect. It can effectively prevent damage to the vehicle caused by rainfall and inconvenience to passengers.

[0067] Furthermore, in one embodiment, the air output is determined based on a preset adjustment coefficient, rainfall amount, an index, a door opening degree coefficient, a window opening degree coefficient and a weight factor, including: determining a first target parameter based on the rainfall amount and the index; adding the product of the window opening degree coefficient and the weight factor to the door opening degree coefficient to obtain a second target parameter; and multiplying the preset adjustment coefficient, the first target parameter and the second target parameter to obtain the air output.

[0068] Specifically, the air volume can be calculated using the following formula:

[0069] V=k1×R a ×(O d +O w ×b)

[0070] Among them, V is the air volume, k1 is the preset adjustment coefficient, R is the rainfall, a is the index, O d is the door opening degree coefficient, O w is the window opening degree coefficient, and b is the weight factor.

[0071] Specifically, the unit of V can be cubic meters per second (m 3 / s), or other appropriate units. k1 is a constant used to adjust the overall output of the formula to meet the needs of the actual system. R can be expressed in millimeters per hour (mm / h) or other appropriate units. a is an index of rainfall, which is used to indicate the degree of influence of rainfall on air output. Usually, a will be a positive number, indicating that the greater the rainfall, the greater the air output. d is the door opening coefficient. When the door opening degree is zero, O d =0; when the door is fully opened, d =1 (or a maximum value, depending on the specific implementation). If the door is partially open, O d Will vary between 0 and 1. w is the window opening degree coefficient, and O d Similarly, when the window is closed, when the window opening degree is zero, O w =0; when the window is fully opened, w =1 (or a certain maximum value). If the window is partially open, then O w It varies between 0 and 1. b is a weighting factor for the effect of window opening on airflow, adjusting the relative influence of window opening on airflow. Typically, b is a positive number, but may be less than or greater than 1, depending on the vehicle design requirements.

[0072] In practice, the above formula may need to be adjusted and optimized according to specific circumstances. In addition, the constants and exponents in the formula (such as k1, a, and b) need to be determined through experiments or data analysis.

[0073] Furthermore, if the intelligent rain protection system requires more precise control, it could be considered to categorize rainfall intensity and door / window opening levels into more levels, with different airflow thresholds or formula parameters set for each level. This would allow for more accurate adjustment of airflow based on real-time conditions, improving both rain protection effectiveness and user experience.

[0074] The vehicle intelligent rain protection method provided in the embodiment of the present application determines the air output of the fan system based on the amount of rainfall, the degree of door opening and the degree of window opening, thereby forming a rainproof barrier. It can accurately determine the size of the rainproof barrier, has a high level of intelligence, and has a good rainproof effect. It can effectively prevent damage to the vehicle caused by rainfall and inconvenience to passengers.

[0075] In one embodiment, the current state of the vehicle is determined based on the detection data of the vehicle's external camera and the detection data of the rain sensor, including: determining a first scene in which the vehicle is located based on the detection data of the external camera; and determining a second scene in which the vehicle is located based on the detection data of the rain sensor; and determining the current state based on the first scene and the second scene.

[0076] Specifically, the external camera captures images of the vehicle's surroundings in real time and uses image recognition technology to determine whether the current scene is a car wash environment, such as a car wash room or car washing machine, thereby determining the first scene. The rain sensor detects rainfall and determines the second scene based on the rainfall. For example, if the rain sensor detects that the rainfall reaches or exceeds a preset threshold, the second scene can be determined to be a rainy scene.

[0077] The vehicle intelligent rain protection method provided in the embodiment of the present application determines the current state of the vehicle based on the detection data of the vehicle's external camera and the detection data of the rain sensor, and takes rain protection measures when the current state is a raining state. It can avoid rain protection in the car washing state or other states, thereby reducing energy consumption.

[0078] Further, in one embodiment, the current state also includes special states and other states; the current state is determined based on the first scene and the second scene, including: when the first scene is a car wash scene and the second scene is a rainfall scene, determining that the current state is a special state; when the first scene is a car wash scene and the second scene is a non-rainfall scene, determining that the current state is a car wash state; when the first scene is a non-car wash scene and the second scene is a rainfall scene, determining that the current state is a rainfall state; when the first scene is a non-car wash scene and the second scene is a non-rainfall scene, determining that the current state is other states.

[0079] A special state can be a state in which the vehicle is experiencing an abnormal condition. Generally, a car would not be washed outdoors during rainfall. If the first scene is detected as a car wash and the second scene is rainfall, it can be treated as a special state. If the first scene is not a car wash and the second scene is not rainfall, the current state is determined to be another state, that is, the vehicle is in a normal driving state outdoors in a non-rainy environment, and rain protection is not required in this case.

[0080] The vehicle intelligent rain protection method provided in the embodiment of the present application determines the current state of the vehicle based on the detection data of the vehicle's external camera and the detection data of the rain sensor, and takes rain protection measures when the current state is a raining state. It can avoid rain protection in the car washing state or other states, thereby reducing energy consumption.

[0081] Furthermore, in one embodiment, the vehicle intelligent rain protection method further includes: when the current state is a special state, redetermining the first scene and the second scene.

[0082] When the current state is a special state, the intelligent rain protection system can re-determine the first scene based on the detection data of the external camera; and re-determine the second scene based on the detection data of the rain sensor.

[0083] The vehicle intelligent rain protection method provided in the embodiment of the present application redetermines the first scene and the second scene when the current state is a special state, so as to accurately confirm the current state and ensure that rain protection measures are taken only in the raining state to reduce energy consumption.

[0084] In one embodiment, the vehicle intelligent rain protection method further includes: when the current state is a rainy state and there is a passenger getting on or off the vehicle, increasing the air output.

[0085] When passengers are getting on or off the bus during rainfall, they need to hold or close umbrellas outside the bus to get on and off, which can easily get the interior equipment (such as seats, floor mats, and door interiors) and passengers wet. This makes it inconvenient to open windows and get on and off the bus. In this case, the air volume can be increased appropriately to form a larger rain barrier. After passengers get on or off the bus and close the doors and windows, the air volume can be reduced appropriately.

[0086] The vehicle intelligent rain protection method provided in the embodiment of the present application increases the air output when the current state is raining and there are passengers getting on or off the vehicle, thereby forming a larger rain protection barrier, which can effectively prevent damage to the vehicle caused by rain and inconvenience to passengers, and improve user experience.

[0087] In one embodiment, the vehicle intelligent rain protection method further includes: obtaining historical data of the vehicle intelligent rain protection and feedback data from passengers on the vehicle's intelligent rain protection effect; and adjusting the air output based on the historical data and the feedback data.

[0088] After each rain protection measure is taken, the intelligent rain protection system can record relevant data, such as the amount of rain, the degree of door and window opening, as well as the fan speed and air volume. The intelligent rain protection system also provides a feedback module to record passenger feedback on the vehicle's intelligent rain protection, such as whether the rain protection effect is satisfactory and whether there is room for improvement. Based on historical data and feedback data, the air volume can be appropriately adjusted to achieve better rain protection. It is worth noting that the feedback data will be stored in an encrypted manner and will only be used to optimize and improve the performance of the intelligent rain protection system to enhance safety.

[0089] The vehicle intelligent rain protection method provided in the embodiment of the present application adjusts the air volume based on historical data and feedback data, which can continuously optimize the rain protection strategy, improve the intelligence level and rain protection effect, and enhance the user experience.

[0090] Based on the description of the above embodiments, the vehicle intelligent rain protection method provided by this application has the following features:

[0091] (1) Accuracy of environmental recognition and judgment. Rainfall is monitored in real time through rain sensors and converted into electrical signals for transmission and processing. This requires the rain sensor to have high precision and high sensitivity, which can accurately reflect the intensity and duration of rainfall, thereby providing a reliable basis for subsequent judgment. The vehicle's external camera is used to capture images of the vehicle's surrounding environment and analyze them through image recognition algorithms. This requires the algorithm to have strong image processing capabilities and be able to accurately identify the difference between the car wash environment and other environments (such as outdoors, parking lots, etc.) to avoid misjudgment.

[0092] (2) Intelligent and automated rain protection function. The need to trigger the rain protection function is determined based on the amount of rainfall and the particularity of the car wash environment. This requires the intelligent rain protection system to have the ability to make intelligent judgments and make accurate decisions based on real-time data. After the rain protection function is triggered, the intelligent rain protection system needs to automatically adjust the air volume and direction according to the rainfall level and the particularity of the car wash environment. This requires the intelligent rain protection system to have precise control capabilities to ensure the best rain protection effect without causing discomfort to passengers.

[0093] (3) Safety and reliability. Ensure that all electrical components meet automotive safety standards and have overcurrent and overvoltage protection mechanisms to avoid safety hazards such as short circuits or overheating. During long-term operation, the intelligent rain protection system needs to maintain stable performance and not be disturbed or affected by the environment. This requires rigorous testing and verification of the intelligent rain protection system to ensure that it can operate normally under various extreme conditions. The intelligent rain protection system has a fault detection function and can issue an alarm in time when a fault occurs, reminding the driver to conduct inspections or repairs.

[0094] (4) Good user experience. By integrating multiple sensors and intelligent algorithms, the system can accurately identify and judge the vehicle's external environment, improving the intelligence of the intelligent rain protection system. The intelligent rain protection system can automatically activate the rain protection function without the driver having to manually operate it, which improves the convenience of use. By adjusting the air volume and direction, the intelligent rain protection system can ensure that passengers will not get wet when getting on and off the vehicle or when reaching out of the window, and will not feel uncomfortable or cold.
