[0047] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Figure 1 Schematic diagram of the process of the vehicle intelligent rain protection method provided by the embodiment of the present application. Figure 1The embodiment of the present application provides a vehicle intelligent rain protection method, which is applied to a vehicle, wherein 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 arranged above the door frame of the vehicle door. The execution subject of the vehicle intelligent rain protection method can be an electronic device, for example, it can be an intelligent rain protection system. The following description takes the execution subject of the method as an example of an intelligent rain protection system.

[0049] The intelligent rain protection system can be composed of a rain sensor, an external camera of the vehicle, a control system, a door status detection module, a window status detection module, a fan system, and an air outlet, etc., to achieve accurate recognition of the external environment of the vehicle, and judge whether it is currently in a raining state or a car wash state. In the raining state, if the door or window is open, the intelligent rain protection system will automatically start the rain protection function, and blow out the air volume matching the current rainfall through the air outlet above the door frame, forming a rain protection barrier, effectively preventing rain from wetting passengers or entering the car.

[0050] Vehicle intelligent rain protection methods can include:

[0051] Step 110: determining 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 a car wash state and a 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 amount of air 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 the 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 the door opening. The window status detection module is used to detect whether the window is in the open state and the degree of the window opening. The fan system is responsible for generating air volume and blowing it out through the air outlet to form a rainproof barrier. The air outlet is located above the door frame and blows out the air volume obliquely to form an effective rainproof barrier.

[0055] In step 110, the intelligent rain protection system can determine the current state of the vehicle through the detection data of the vehicle's external camera and the detection data of the rain sensor. The current state includes a car wash state and a rain state. By excluding the car wash state of the vehicle, the intelligent rain protection system can be prevented from taking rain protection measures to protect against rain in the car wash state.

[0056] In step 120, the intelligent rain protection system needs to take rain protection measures only when it determines that the current state of the vehicle is a raining state. The intelligent rain protection system can determine the amount of rain through 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.

[0057] The intelligent rain protection system can obtain detection data by monitoring rainfall in real time through rain sensors. Rain sensors usually use photoelectric sensing or piezoelectric sensing to accurately sense the size, quantity and speed of raindrops, thereby calculating the rainfall. According to the detection data of the rain sensor, the intelligent rain protection system can divide the rainfall into different levels, such as light rain, moderate rain, heavy rain, etc., or divide it into more detailed levels, and can learn and adjust intelligently. Each level corresponds to different rain protection needs. For example, light rain may only require slight rain protection, while heavy rain requires stronger 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 volume of the fan system based on the amount of rainfall, the degree of door opening and the degree of window opening. The air output of the fan system is blown out obliquely through the air outlet above the door frame of the door to form a rainproof barrier. The air volume of the fan system can be achieved by adjusting the speed of the fan system. Safety factors such as overheating protection and overload protection are taken into consideration when designing the fan system. During long-term operation or abnormal conditions, the intelligent rain protection system can automatically shut down the fan system to prevent damage or safety problems.

[0060] Specifically, when the level of rainfall is light rain, if the door or window opening degree is not zero, the intelligent rain protection system will determine the air volume according to the opening degree. Generally speaking, the air volume can be smaller during light rain, because light rain will cause relatively less intrusion to the interior of the car. If the door or window is partially opened, the intelligent rain protection system may choose a lower air volume to avoid unnecessary energy consumption and noise. If the door or window is fully opened, the intelligent rain protection system will appropriately increase the air volume to ensure the rain protection effect.

[0061] When the rainfall is moderate, the air volume will generally be larger than that of light rain to cope with stronger rain. If the door or window is partially open, the intelligent rain protection system will select a moderate air volume to strike a balance between rain protection and energy consumption. If the door or window is fully open, the intelligent rain protection system will significantly increase the air volume to ensure that the interior of the car is not wetted by rain.

[0062] When the rainfall is heavy, the intelligent rain protection system needs to ensure the strongest rain protection effect. Therefore, when the doors and windows are not open to zero, the intelligent rain protection system will choose the maximum air volume to deal with it. It should be noted that in heavy rain, even if the doors and windows are open to zero, the intelligent rain protection system may start the fan system and blow out an appropriate amount of air through the air outlet to prevent rain from entering the car through the gaps.

[0063] 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 by judging the current state of the vehicle and when the current state is a raining state, thereby forming a rainproof barrier. The size of the rainproof barrier can be accurately determined, the level of intelligence is high, the rain protection effect is good, and the damage to the vehicle caused by rainfall and the inconvenience to passengers can be effectively prevented.

[0064] In one embodiment, based on the amount of rainfall, the degree of door opening and the degree of window opening, the amount of air blown out obliquely from the air outlet by the fan system is determined, 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 for the degree of 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 rain protection barrier. The size of the rain protection barrier can be accurately determined, the level of intelligence is high, the rain protection effect is good, and the damage to the vehicle caused by rainfall and the inconvenience to passengers can be effectively prevented.

[0067] Furthermore, in one embodiment, the air volume 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 volume.

[0068] Specifically, the air volume can be calculated by 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, V can be expressed in 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 degree coefficient. When the door opening degree is zero, O d =0; when the door is fully opened, O 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 will vary between 0 and 1. b is the weight factor of the effect of window opening on air volume, which is used to adjust the relative effect of window opening on air volume. Usually, b will be a positive number, but may be less than or greater than 1, depending on the requirements of vehicle design.

[0072] In actual application, 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] In addition, if the intelligent rain protection system requires more precise control, it is also possible to consider dividing the rainfall and the degree of door / window opening into more levels, and setting different air volume thresholds or formula parameters for each level. This can more accurately adjust the air volume according to the real-time situation, improve the rain protection effect 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 rain protection barrier. The size of the rain protection barrier can be accurately determined, the level of intelligence is high, the rain protection effect is good, and the damage to the vehicle caused by rainfall and the inconvenience to passengers can be effectively prevented.

[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 will capture images around the vehicle in real time, and determine whether the current scene is a car wash environment, such as a car wash room or a car washing machine, through image recognition technology, thereby determining the first scene. The rain sensor will detect the rainfall and determine the second scene based on the rainfall. For example, when the rain sensor detects that the rainfall reaches or exceeds a preset threshold, the second scene can be determined to be a rainfall 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 rainfall state, which 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; based on the first scene and the second scene, the current state is determined, including: when the first scene is a car wash scene and the second scene is a rainfall scene, the current state is determined to be a special state; when the first scene is a car wash scene and the second scene is a non-rainfall scene, the current state is determined to be a car wash state; when the first scene is a non-car wash scene and the second scene is a rainfall scene, the current state is determined to be a rainfall state; when the first scene is a non-car wash scene and the second scene is a non-rainfall scene, the current state is determined to be other states.

[0079] The special state may be a state in which the vehicle is in an abnormal condition. Generally speaking, a car will not be washed outdoors during rain. If the first scene is detected as a car wash scene and the second scene is a rain scene, it can be treated as a special state. When the first scene is not a car wash scene and the second scene is not a rain scene, the current state is determined to be another state, that is, the vehicle is in a normal driving state outdoors in a non-rain scene, and rain protection is not required at this time.

[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 rainfall state, which 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 redefines 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 rainfall 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 are passengers getting on or getting off the vehicle, increasing the air volume.

[0085] When it is raining and passengers are getting on or off the bus, they need to hold or close umbrellas outside the bus to get on or off, which can easily get the equipment inside the bus (such as seats, floor mats, inside doors, etc.) and people wet, making it inconvenient to open windows or get on or off the bus. At this time, the air volume can be appropriately increased to form a larger rainproof barrier. After passengers get on or off the bus and close the doors and windows, the air volume can be appropriately reduced.

[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 getting 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, thereby improving the user experience.

[0087] In one embodiment, the vehicle intelligent rain protection method further includes: acquiring 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 volume based on the historical data and the feedback data.

[0088] The intelligent rain protection system can record relevant data every time it takes rain protection measures, such as the amount of rain, the degree of door opening, the degree of window opening, the fan speed, the air volume and other data. The intelligent rain protection system can also provide a feedback module to record passengers' feedback on the vehicle's intelligent rain protection effect, 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 adjusted appropriately to achieve better rain protection effects. It is worth noting that the feedback data will be encrypted and stored, and will only be used to optimize and improve the performance of the intelligent rain protection system to improve 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 characteristics:

[0091] (1) Accuracy of environmental identification and judgment. Rainfall is monitored in real time through rain sensors and converted into electrical signals for transmission and processing. This requires the rain sensors to have high precision and high sensitivity, and to accurately reflect the intensity and duration of rainfall, thus providing a reliable basis for subsequent judgments. The vehicle's external camera is used to capture images of the vehicle's surroundings, and the images are analyzed using image recognition algorithms. This requires the algorithm to have strong image processing capabilities, and 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. Determine whether to trigger the rain protection function 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 based on 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 and not cause 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 smart rain protection system needs to maintain stable performance without being disturbed or affected by the environment. This requires rigorous testing and verification of the smart rain protection system to ensure that it can work normally under various extreme conditions. The smart rain protection system has a fault detection function and can issue an alarm in time when a fault occurs, reminding the driver to perform inspections or repairs.

[0094] (4) Good user experience. By integrating multiple sensors and intelligent algorithms, the vehicle's external environment can be accurately identified and judged, improving the intelligence of the intelligent rain protection system. The intelligent rain protection system can automatically activate the rain protection function without the driver's manual operation, 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 putting their hands out of the window, and will not feel uncomfortable or cold.

[0095] The vehicle intelligent rain protection device provided in the present application is described below. The vehicle intelligent rain protection device described below and the vehicle intelligent rain protection method described above can be referenced to each other.
