Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, device, vehicle, equipment and medium for automatic vehicle response in rainy weather. Background Technology

[0002] As the level of automotive intelligence continues to improve, users' demand for convenience and comfort in driving is growing.

[0003] In everyday rainy driving scenarios, users need to manually open the door, find and open the umbrella in the rain. This process not only easily causes the driver and passengers to get wet, but also makes it easy for rainwater to enter the car, wetting the seats and interior, affecting the riding experience.

[0004] To address these issues, some technologies have incorporated dedicated umbrella storage compartments within car doors; for example, some high-end models store umbrellas in a door interlayer. However, such designs still rely on users manually retrieving, opening, and returning the umbrella, resulting in low automation and failing to fundamentally simplify the process of using a car in rainy weather. This requires immediate attention and a solution. Summary of the Invention

By realizing the intelligent linkage of rain detection, automatic door opening, and synchronous pop-out of the built-in umbrella, the convenience and intelligent experience of vehicle use are significantly improved.

[0006] The first aspect of this application provides a method for automatic vehicle response in rainy weather, including the following steps: Acquire rainfall data and user perception data of the current vehicle's environment; Determine whether the rainfall data of the current vehicle environment and the user perception data meet the preset automatic response conditions; When the rainfall data of the current vehicle's environment and the user's perception data meet the preset automatic response conditions, the vehicle door is controlled to pre-open based on a first preset angle, and the vehicle's built-in umbrella is controlled to pop out. Based on the rainfall data of the current vehicle's environment, the vehicle door is controlled to continue opening to a target preset angle, wherein the target preset angle is greater than the first preset angle.

[0007] According to one embodiment of this application, determining whether the rainfall data of the current vehicle's environment and the user-perceived data meet preset automatic response conditions includes: The rainfall data of the current vehicle's environment is analyzed to obtain the current humidity and the number of raindrops per unit time and per unit area. The user perception data is analyzed to obtain the Bluetooth key signal strength of the current vehicle and the facial recognition matching degree of the current user; If the humidity of the current environment is greater than a preset humidity, the number of raindrops per unit time and per unit area is greater than a preset number, the Bluetooth key signal strength of the current vehicle is greater than a preset strength, and the facial recognition matching degree of the current user is greater than a preset matching degree, then the rainfall data of the current vehicle's environment and the user's perception data are determined to meet the preset automatic response conditions; otherwise, the rainfall data of the current vehicle's environment and the user's perception data are determined not to meet the preset automatic response conditions.

[0008] According to one embodiment of this application, controlling the door of the current vehicle to continue opening to a target preset angle based on rainfall data of the current vehicle's environment includes: The current rainfall intensity signal is determined based on the rainfall data of the current vehicle's environment; If the current rainfall intensity signal is within the first preset rainfall intensity signal range, then the target preset angle is determined to be the second preset angle; Based on the second preset angle, a first angle control command is generated, which controls the door servo system of the current vehicle to adjust the damping torque of the limit damper and the driving time of the electric door lock module according to the first angle control command, so that the door of the current vehicle opens to the second preset angle.

[0009] According to one embodiment of this application, after determining the current rainfall intensity signal based on the rainfall data of the current vehicle's environment, the method further includes: If the current rainfall intensity signal is within the second preset rainfall intensity signal range, then the target preset angle is determined to be the third preset angle; Based on the third preset angle, a second angle control command is generated, and the door servo system of the current vehicle is controlled to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the second angle control command, so that the door of the current vehicle is opened to the third preset angle. Wherein, the lower limit of the second preset rainfall intensity signal interval is greater than the upper limit of the first preset rainfall intensity signal interval, and the third preset angle is greater than the second preset angle.

[0010] According to one embodiment of this application, after controlling the door of the current vehicle to open based on a second preset angle, the method further includes: Determine whether the vehicle's built-in umbrella is in a preset recovery position; When the built-in umbrella of the current vehicle is in the preset recycling position, the built-in umbrella is dried until the duration of the drying process is greater than or equal to the preset duration. The drying process is then considered complete, and a notification is given that the drying process is complete.

[0011] According to the automatic vehicle response method in rainy weather provided in this application embodiment, when the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions, the vehicle door is controlled to pre-open at a first preset angle, and the built-in umbrella of the current vehicle is controlled to pop out. Furthermore, based on the rainfall data of the current vehicle's environment, the vehicle door is controlled to continue opening to a target preset angle. This solves the problem in related technologies where the door system and rain gear functions are independent and lack intelligent linkage, resulting in users still needing to manually operate the system when getting in and out of the vehicle in rainy weather, being easily wetted, and water entering the vehicle compartment. By achieving intelligent linkage between rainfall detection, automatic door opening, and synchronized pop-out of the built-in umbrella, the convenience and intelligent experience of vehicle use are significantly improved.

[0012] A second aspect of this application provides a vehicle automatic response device for rainy weather, comprising: The acquisition module is used to acquire rainfall data and user perception data of the current vehicle environment; The judgment module is used to determine whether the rainfall data of the current vehicle environment and the user perception data meet the preset automatic response conditions; The control module is configured to, when the rainfall data of the current vehicle's environment and the user perception data meet the preset automatic response conditions, control the door of the current vehicle to pre-open based on a first preset angle, and control the built-in umbrella of the current vehicle to pop out, and, based on the rainfall data of the current vehicle's environment, control the door of the current vehicle to continue opening to a target preset angle, wherein the target preset angle is greater than the first preset angle.

[0013] According to one embodiment of this application, the determining module is configured to: The rainfall data of the current vehicle's environment is analyzed to obtain the current humidity and the number of raindrops per unit time and per unit area. The user perception data is analyzed to obtain the Bluetooth key signal strength of the current vehicle and the facial recognition matching degree of the current user; If the humidity of the current environment is greater than a preset humidity, the number of raindrops per unit time and per unit area is greater than a preset number, the Bluetooth key signal strength of the current vehicle is greater than a preset strength, and the facial recognition matching degree of the current user is greater than a preset matching degree, then the rainfall data of the current vehicle's environment and the user's perception data are determined to meet the preset automatic response conditions; otherwise, the rainfall data of the current vehicle's environment and the user's perception data are determined not to meet the preset automatic response conditions.

[0014] According to one embodiment of this application, the control module is configured to: The current rainfall intensity signal is determined based on the rainfall data of the current vehicle's environment; If the current rainfall intensity signal is within the first preset rainfall intensity signal range, then the target preset angle is determined to be the second preset angle; Based on the second preset angle, a first angle control command is generated, which controls the door servo system of the current vehicle to adjust the damping torque of the limit damper and the driving time of the electric door lock module according to the first angle control command, so that the door of the current vehicle opens to the second preset angle.

[0015] According to one embodiment of this application, after determining the current rainfall intensity signal based on the rainfall data of the current vehicle's environment, the control module is further configured to: If the current rainfall intensity signal is within the second preset rainfall intensity signal range, then the target preset angle is determined to be the third preset angle; Based on the third preset angle, a second angle control command is generated, and the door servo system of the current vehicle is controlled to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the second angle control command, so that the door of the current vehicle is opened to the third preset angle. Wherein, the lower limit of the second preset rainfall intensity signal interval is greater than the upper limit of the first preset rainfall intensity signal interval, and the third preset angle is greater than the second preset angle.

[0016] According to one embodiment of this application, after controlling the door of the current vehicle to open based on a second preset angle, the control module is further configured to: Determine whether the vehicle's built-in umbrella is in a preset recovery position; When the built-in umbrella of the current vehicle is in the preset recycling position, the built-in umbrella is dried until the duration of the drying process is greater than or equal to the preset duration. The drying process is then considered complete, and a notification is given that the drying process is complete.

[0017] According to the rain-time vehicle automatic response device provided in this application embodiment, when the rainfall data and user perception data of the current vehicle's environment meet preset automatic response conditions, the device controls the vehicle door to pre-open at a first preset angle and controls the vehicle's built-in umbrella to pop out. Furthermore, based on the rainfall data of the current vehicle's environment, the device controls the vehicle door to continue opening to a target preset angle. This solves the problem in related technologies where the door system and rain gear functions are independent and lack intelligent linkage, resulting in users still needing to manually operate the system when getting in and out of the vehicle in rainy weather, being easily wetted, and water entering the vehicle compartment. By achieving intelligent linkage between rainfall detection, automatic door opening, and synchronized pop-out of the built-in umbrella, the device significantly improves the convenience and intelligent experience of vehicle use.

[0022] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a flowchart of an automatic vehicle response method in rainy weather provided according to an embodiment of this application; Figure 2 This is a schematic diagram illustrating the working principle of an intelligent system based on rain detection that automatically opens car doors and pops out a built-in umbrella according to an embodiment of this application. Figure 3 This is a block diagram of a vehicle automatic response device in rainy weather according to an embodiment of this application; Figure 4 This is a schematic diagram of the vehicle structure provided in an embodiment of this application. Detailed Implementation

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] Those skilled in the art will understand that existing vehicles suffer from inconvenient and time-consuming umbrella access in rainy weather, and rainwater easily wets the seats when the doors are opened. Although some high-end models are equipped with built-in umbrella slots in the doors, they still rely on manual access and lack an intelligent response mechanism for rainy weather. Furthermore, there is no effective linkage between the door system and the umbrella function. Existing technologies have failed to achieve an intelligent closed loop of "detecting rainfall - automatically opening the door - simultaneously popping out the umbrella".

[0025] Based on the technical problems existing in the aforementioned related technologies, this application proposes an automatic vehicle response method in rainy weather. This method can monitor whether it is raining in real time, and automatically open the door and simultaneously pop out an umbrella when rain is detected and the owner approaches the vehicle. This avoids getting the seats or the owner wet when the door is opened in the rain, improving the riding experience and realizing an intelligent closed loop of "detecting rain - automatically opening the door - simultaneously popping out an umbrella". It is applicable to various passenger vehicles such as private cars, taxis, and ride-hailing vehicles, and enhances the user's driving experience in rainy weather.

[0026] The following description, with reference to the accompanying drawings, describes an embodiment of a rain-fighting vehicle automatic response method, apparatus, vehicle, equipment, and medium.

[0027] Specifically, Figure 1 This is a flowchart illustrating an automatic vehicle response method in rainy weather, provided in an embodiment of this application.

[0028] like Figure 1 As shown, the automatic vehicle response method in rainy weather includes the following steps: In step S101, rainfall data and user perception data of the current vehicle environment are obtained.

[0029] The rainfall data of the current vehicle environment may include the number of raindrops distributed per unit time and per unit area, raindrop impact kinetic energy data, and ambient relative humidity value. User perception data may include Bluetooth signal reception strength indication values ​​from user terminals (such as smartphones or smart keys), user biometric image data (such as facial images), etc., without specific limitations.

[0030] Specifically, embodiments of this application can utilize an optical rain sensor installed on the windshield to measure the number of raindrops distributed per unit time and per unit area and the impact frequency, utilize a piezoelectric raindrop sensor installed on the roof of the vehicle to sense the kinetic energy data of raindrop impact, and utilize a capacitive humidity sensor integrated in the exterior rearview mirror area to detect the ambient relative humidity value.

[0031] Furthermore, in this embodiment, the vehicle's Bluetooth communication module can receive Bluetooth signal reception strength indication values ​​from user terminals (such as smartphones or smart keys) to determine the relative distance between the user and the vehicle; it can also detect pressure change signals caused by the user approaching or standing by a pressure sensor installed on the side of the car door; and it can also collect user biometric image data (such as facial images) from the vehicle's camera for subsequent identity matching and verification, without specific limitations.

[0032] In step S102, it is determined whether the rainfall data and user perception data of the current vehicle environment meet the preset automatic response conditions.

[0033] Furthermore, in some embodiments, determining whether the rainfall data and user perception data of the current vehicle's environment meet preset automatic response conditions includes: parsing the rainfall data of the current vehicle's environment to obtain the humidity of the current environment and the number of raindrops per unit time and unit area; parsing the user perception data to obtain the Bluetooth key signal strength of the current vehicle and the face recognition matching degree of the current user; if the humidity of the current environment is greater than a preset humidity, and the number of raindrops per unit time and unit area is greater than a preset number, and the Bluetooth key signal strength of the current vehicle is greater than a preset strength, and the face recognition matching degree of the current user is greater than a preset matching degree, then the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions; otherwise, the rainfall data and user perception data of the current vehicle's environment do not meet the preset automatic response conditions.

[0034] Specifically, the humidity percentage of the current environment is extracted from the signal output by the capacitive humidity sensor; at the same time, the data monitored by the optical rain gauge is processed to calculate the number of raindrops identified in a standard unit area within a specific unit time window, which serves as a key indicator for quantifying rainfall intensity.

[0035] This application embodiment can also obtain the Bluetooth key signal strength of the current vehicle by parsing Bluetooth communication protocol data packets. The strength value is inversely proportional to the physical distance between the user terminal and the vehicle, and is an important basis for determining whether the user has entered the effective triggering area. At the same time, a face recognition algorithm is called to compare the user's facial image captured in real time by the vehicle camera with the authorized user feature template pre-stored in the system, and output a confidence score representing the degree of similarity, that is, the face recognition matching degree of the current user.

[0036] Furthermore, when the current ambient humidity value obtained from the analysis exceeds a preset humidity threshold (e.g., 70%), and the calculated number of raindrops per unit area per unit time is greater than a preset number threshold (e.g., 6 consecutive drops / 10cm), the humidity will be further determined. 2 If the Bluetooth key signal strength is higher than the preset strength threshold, indicating that the user has entered the preset close range (e.g., within 3.5 meters), and the face recognition matching degree is higher than the preset matching degree threshold, then it is determined that the rainfall data and user perception data of the current vehicle environment meet the preset automatic response conditions. If any of the above conditions do not reach their corresponding thresholds, it is determined that the automatic response conditions are not met, and the standby state will be maintained.

[0037] In step S103, if the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions, the current vehicle's door is controlled to pre-open based on a first preset angle, and the built-in umbrella of the current vehicle is controlled to pop out. According to the rainfall data of the current vehicle's environment, the current vehicle's door is controlled to continue opening to a target preset angle, wherein the target preset angle is greater than the first preset angle.

[0038] Optionally, the first preset angle can be 15°, without specific limitation.

[0039] Specifically, when the rainfall data and user perception data of the current vehicle environment meet the preset automatic response conditions, a command is sent to the door servo system to control its drive of the electric door lock module, causing the door to unlock and open to a small, preparatory first preset angle (e.g., 15°). This pre-opening angle is set to achieve two main purposes: first, to provide the user with clear visual feedback that the system is activated through a small door gap; second, to reserve the necessary physical space for the smooth deployment of the umbrella, avoiding interference between the door and the umbrella mechanism.

[0040] Furthermore, as the car door begins to pre-open, a trigger command is simultaneously sent to the umbrella ejection mechanism. This command activates the compressed air-driven ejection system, rapidly and smoothly launching the built-in umbrella stored in the umbrella storage module within the car door interlayer. During ejection, the umbrella ribs automatically unfold due to the properties of the shape memory alloy, and guided and constrained by an electromagnetic positioning device, the umbrella handle ultimately reaches and stabilizes in a pre-grip position convenient for the user (e.g., approximately 1.2 meters above the ground).

[0041] Furthermore, in some embodiments, controlling the vehicle door to continue opening to a target preset angle based on rainfall data of the current vehicle's environment includes: determining the current rainfall intensity signal based on the rainfall data of the current vehicle's environment; if the current rainfall intensity signal is within a first preset rainfall intensity signal range, then determining the target preset angle as a second preset angle; generating a first angle control command based on the second preset angle, and controlling the vehicle door servo system to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the first angle control command, so that the vehicle door opens to the second preset angle.

[0042] Specifically, the current rainfall intensity signal is determined based on rainfall data from the vehicle's current environment. This rainfall intensity signal is a comprehensive index used to quantify rainfall intensity, derived through algorithmic processing of data from both optical rain gauges and piezoelectric raindrop sensors.

[0043] If the current rainfall intensity signal is determined to fall within a first preset rainfall intensity signal range (e.g., corresponding to light or moderate rain intensity range), then a second preset angle (e.g., 40°) will be determined accordingly. After the target angle is determined, a first angle control command will be generated based on the second preset angle. This command contains the precise control parameters required to achieve a specific door opening angle.

[0044] Furthermore, the door servo system, upon receiving commands, precisely adjusts the damping torque of the limit damper to control the resistance and smoothness of door opening; simultaneously, it controls the drive duration of the electric door lock module to precisely control the door opening stroke. Through the coordinated control of these two key actuators, the vehicle door can ultimately open accurately and smoothly to the set second preset angle, thus ensuring both convenience in rainy weather and operational safety and reliability.

[0045] Furthermore, in some embodiments, after determining the current rainfall intensity signal based on the rainfall data of the current vehicle's environment, the method further includes: if the current rainfall intensity signal is within a second preset rainfall intensity signal range, then determining the target preset angle as a third preset angle; generating a second angle control command based on the third preset angle, and controlling the current vehicle's door servo system to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the second angle control command, so that the current vehicle's door opens to the third preset angle; wherein, the lower limit of the second preset rainfall intensity signal range is greater than the upper limit of the first preset rainfall intensity signal range, and the third preset angle is greater than the second preset angle.

[0046] Specifically, if the current rainfall intensity signal is within the second preset rainfall intensity signal range, it indicates that stronger rainfall (such as heavy rain or torrential rain) is currently occurring. To ensure that users have sufficient shelter during getting on and off the vehicle and to minimize the amount of rain on their bodies, the intelligent control module will make a decision based on this and determine the target preset angle as the third preset angle (such as 60°).

[0047] After the decision is made, a second angle control command is generated based on the third preset angle. The vehicle's door servo system then executes precise actions according to this command: on one hand, the damping torque of the limit damper is reduced to decrease the resistance encountered by the door during its larger opening stroke, ensuring a smooth and effortless opening process; on the other hand, the driving time of the electric door lock module is appropriately extended to provide the door with more operating time, allowing it sufficient travel to reach a larger opening angle. Through this coordinated control of damping torque and driving time, the door servo system can drive the door smoothly and accurately to the final third preset angle, thus providing users with a more spacious and protected passageway even in heavy rainfall.

[0048] For example, if the optical sensor detects 6 drops / 10cm consecutively 2 If it rains and the humidity sensor confirms that the ambient humidity is >70%, the control system enters rainy standby mode. If the Bluetooth key detects that the owner has entered within 3.5 meters and the pressure sensor senses that the occupant is standing next to the door, the camera performs facial recognition to confirm the identity. If the identity is successfully confirmed, the door is unlocked and a 15° pre-opening begins, the umbrella ejection mechanism is activated, and the door continues to open to the set angle (40° for light rain, 60° for heavy rain) until the umbrella is fully open (completed within 2 seconds).

[0049] Furthermore, in some embodiments, after controlling the current vehicle door to open based on a second preset angle, the method further includes: determining whether the current vehicle's built-in umbrella is in a preset retractable position; if the current vehicle's built-in umbrella is in the preset retractable position, performing a drying process on the built-in umbrella until the duration of the drying process on the built-in umbrella is greater than or equal to a preset duration, determining that the drying process is complete, and providing a reminder that the drying process is complete.

[0050] Optionally, the preset duration can be 15 minutes, without any specific limit.

[0051] Specifically, in this embodiment, sensors (such as pressure sensors or RFID readers) installed in the umbrella storage compartment can detect whether the umbrella has been correctly returned to its position and locked. When the sensors confirm that the built-in umbrella has accurately returned and is fixed in the preset recycling position, an automatic maintenance program is initiated to perform a drying process on the built-in umbrella. This process can be completed by a heating device and an airflow circulation system integrated into the umbrella compartment, aiming to remove residual moisture from the umbrella surface and ribs, prevent mold growth, and keep the compartment dry. The system continuously monitors the running time of the drying program, and only determines that the drying operation is officially completed when the duration of the drying process reaches or exceeds the preset duration (e.g., 15 minutes).

[0052] To provide users with clear status feedback, a notification is sent upon completion of the drying process. This notification function can be implemented through various human-machine interfaces, such as displaying prompts on the vehicle's central control screen, issuing voice prompts, or pushing a "The umbrella is dry and ready" notification to the user via a linked mobile application. This ensures that the umbrella can be promptly restored to a dry and clean state after use, enhancing the system's intelligence and user experience.

[0053] For example, an infrared sensor will detect whether the driver has successfully boarded the vehicle to determine if the umbrella has been used. If the driver has boarded, the umbrella will be retracted after use. A guide light will indicate the position of the umbrella retraction slot during retraction. The indicator light will turn green when the umbrella is fully retracted, and red if it is not fully retracted or is still in use. After retraction, the umbrella compartment will be automatically dried and sterilized with hot air for 15 minutes.

[0054] The following is a detailed description of the intelligent system proposed in this application, which automatically opens the car door and pops out a built-in umbrella based on rain detection.

[0055] Specifically, this intelligent system, which automatically opens the car door and pops out a built-in umbrella based on rain detection, uses an environmental perception module, an umbrella storage module, an actuator module, and an intelligent control module to detect in real time whether it is raining and whether the car owner is approaching the vehicle via Bluetooth key positioning. When it detects rain and the car owner is approaching the vehicle, it automatically opens the car door and pops out the umbrella at the same time.

[0056] Furthermore, the environmental perception module includes a multi-mode rain sensor and a door status detection unit. The multi-mode rain sensor consists of an optical rain sensor for the windshield, a piezoelectric raindrop sensor for the roof, and a capacitive humidity sensor for the rearview mirror area, installed on the windshield, roof, and rearview mirror areas respectively to detect rainfall. The door status detection unit consists of a Hall sensor and a pressure sensor installed on the door. The Hall sensor detects the door opening angle, and the pressure sensor detects the approach of occupants.

[0057] Furthermore, the umbrella storage module includes a three-dimensional telescopic umbrella compartment and an umbrella positioning system. The three-dimensional telescopic umbrella compartment is concealed within the door's interlayer space; the umbrella ribs are made of shape-memory alloy for automatic deployment, and the umbrella surface uses a hydrophobic nano-coating. It automatically opens when a rain sensor detects rain and the vehicle owner is near. The umbrella positioning system uses RFID tags to track the umbrella's position and pressure sensors to detect the umbrella's retraction status.

[0058] The actuator module includes a door servo system and an umbrella ejection mechanism. The door servo system consists of an electric door lock control module located below the door and a limit damper that adjusts the door opening angle. The limit damper adjusts the opening angle based on the monitored rainfall (40° for light rain, 60° for heavy rain). The umbrella ejection mechanism uses compressed air to drive the ejection system, and an electromagnetic positioning device ensures the umbrella handle reaches the optimal grip position.

[0059] Furthermore, the intelligent control module includes a decision-making main control unit and a human-machine interface. The decision-making main control unit fuses data from multiple sensors in real time and uses a fuzzy control algorithm to determine the timing of actions, ensuring the automatic opening of the doors and the automatic deployment of the umbrella are carried out in an orderly manner. The human-machine interface includes a vehicle screen display, voice prompts, and remote control via a mobile app. The vehicle screen displays the umbrella's status (whether it is closed or open, and whether the umbrella is functioning correctly), the vehicle supports voice prompts such as "Rain mode activated," and the mobile app allows remote viewing of the umbrella's position.

[0060] Therefore, this invention achieves fully automatic intelligent response in rainy weather by automating the entire process of "detection-door opening-umbrella pop-out". The umbrella handle pop-out height can be set according to the average adult grip position of 1.2 m, which meets the requirements of ergonomics. The system can automatically adjust the door opening angle and umbrella unfolding size according to the real-time rainfall level, taking into account both windproof in light rain and rainproof effect in heavy rain. Each functional unit adopts a modular design, which supports quick plug-and-play replacement of umbrella and inflation components, making maintenance convenient.

[0061] To facilitate a clearer and more intuitive understanding by those skilled in the art of the working principle of the intelligent system based on rain detection that automatically opens car doors and pops out a built-in umbrella according to the embodiments of this application, the following is a detailed explanation. Figure 2 Provide an example.

[0062] like Figure 2 As shown, this intelligent system, which automatically opens the car door and pops out a built-in umbrella based on rain detection, uses an environmental perception module and an intelligent control module to detect 6 consecutive drops / 10cm. 2 When it rains and the humidity sensor confirms that the ambient humidity is >70% and the owner's mobile phone location is within 3.5 meters, the camera performs facial recognition to confirm identity. Once the owner is identified, the vehicle's voice prompts "Rain mode activated," the door opens 15°, an oversized umbrella (1.2m in diameter) pops out, and the door opens to 60°. After the owner successfully gets in, the umbrella automatically starts a drying program and performs ozone sterilization for 15 minutes when it is put back in the car. The app pushes a "Umbrella in place" notification, and the umbrella indicator light turns green.

[0063] According to the automatic vehicle response method for rainy weather proposed in this application, when the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions, the vehicle door is pre-opened at a first preset angle, and the vehicle's built-in umbrella pops out. Furthermore, based on the rainfall data of the current vehicle's environment, the vehicle door continues to open to a target preset angle. This solves the problem in related technologies where the door system and rain gear functions are independent and lack intelligent linkage, resulting in users still needing to manually operate the system when getting in and out of the vehicle in rainy weather, being easily wetted, and water entering the vehicle compartment. By achieving intelligent linkage between rainfall detection, automatic door opening, and synchronized umbrella pop-out, the convenience and intelligent experience of vehicle use are significantly improved.

[0064] Next, the automatic response device for vehicles in rainy weather according to an embodiment of this application is described with reference to the accompanying drawings.

[0065] Figure 3 This is a block diagram of the automatic vehicle response device in rainy weather according to an embodiment of this application.

[0066] like Figure 3As shown, the automatic response device 10 for vehicles in rainy weather includes: an acquisition module 100, a judgment module 200, and a control module 300.

[0067] The system includes an acquisition module 100 for acquiring rainfall data and user perception data of the current vehicle's environment; a judgment module 200 for judging whether the rainfall data and user perception data of the current vehicle's environment meet preset automatic response conditions; and a control module 300 for controlling the vehicle's doors to pre-open based on a first preset angle and controlling the vehicle's built-in umbrella to pop out when the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions, and controlling the vehicle's doors to continue opening to a target preset angle based on the rainfall data of the current vehicle's environment, wherein the target preset angle is greater than the first preset angle.

[0068] Furthermore, in some embodiments, the judgment module 200 is configured to: analyze the rainfall data of the current vehicle's environment to obtain the humidity of the current environment and the number of raindrops per unit time and per unit area; analyze the user perception data to obtain the Bluetooth key signal strength of the current vehicle and the face recognition matching degree of the current user; if the humidity of the current environment is greater than a preset humidity, and the number of raindrops per unit time and per unit area is greater than a preset number, and the Bluetooth key signal strength of the current vehicle is greater than a preset strength, and the face recognition matching degree of the current user is greater than a preset matching degree, then the judgment module 200 is configured to determine that the rainfall data and user perception data of the current vehicle's environment meet the preset automatic response conditions; otherwise, the judgment module 200 is configured to determine that the rainfall data and user perception data of the current vehicle's environment do not meet the preset automatic response conditions.

[0069] Furthermore, in some embodiments, the control module 300 is configured to: determine the current rainfall intensity signal based on the rainfall data of the current vehicle's environment; if the current rainfall intensity signal is within a first preset rainfall intensity signal range, determine the target preset angle as a second preset angle; generate a first angle control command based on the second preset angle, and control the current vehicle's door servo system to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the first angle control command, so that the current vehicle's door opens to the second preset angle.

[0070] Furthermore, in some embodiments, after determining the current rainfall intensity signal based on the rainfall data of the current vehicle's environment, the control module 300 is further configured to: if the current rainfall intensity signal is within a second preset rainfall intensity signal range, determine the target preset angle as a third preset angle; generate a second angle control command based on the third preset angle, and control the current vehicle's door servo system to adjust the damping torque of the limit damper and the driving duration of the electric door lock module according to the second angle control command, so that the current vehicle's door opens to the third preset angle; wherein, the lower limit of the second preset rainfall intensity signal range is greater than the upper limit of the first preset rainfall intensity signal range, and the third preset angle is greater than the second preset angle.

[0071] Furthermore, in some embodiments, after controlling the current vehicle door to open based on a second preset angle, the control module 300 is also used to: determine whether the built-in umbrella of the current vehicle is in a preset retraction position; if the built-in umbrella of the current vehicle is in the preset retraction position, perform a drying process on the built-in umbrella until the duration of the drying process on the built-in umbrella is greater than or equal to a preset duration, determine that the drying process is completed, and provide a reminder that the drying process is completed.

[0072] It should be noted that the foregoing explanation of the embodiment of the automatic response method for vehicles in rainy weather also applies to the automatic response device for vehicles in rainy weather in this embodiment, and will not be repeated here.

[0073] According to the rain-time vehicle automatic response device proposed in this application embodiment, when the rainfall data and user perception data of the current vehicle's environment meet preset automatic response conditions, the device controls the vehicle door to pre-open at a first preset angle and controls the vehicle's built-in umbrella to pop out. Furthermore, based on the rainfall data of the current vehicle's environment, the device controls the vehicle door to continue opening to a target preset angle. This solves the problem in related technologies where the door system and rain gear functions are independent and lack intelligent linkage, resulting in users still needing to manually operate the system when getting in and out of the vehicle in rainy weather, being easily wetted, and water entering the vehicle compartment. By achieving intelligent linkage between rainfall detection, automatic door opening, and synchronized pop-out of the built-in umbrella, the device significantly improves the convenience and intelligent experience of vehicle use.
