[0013] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In this application, the terms "first" and "second" are used to distinguish between identical or similar items that have essentially the same function. It should be understood that there is no logical or temporal dependency between "first" and "second", nor is there any limitation on the quantity or execution order.

[0015] first, Figure 1 A structural block diagram of a computer system provided in an exemplary embodiment of this application is shown. Based on this structural block diagram, the execution process of the control method for an in-vehicle terminal provided in an embodiment of this application will be described. The computer system is implemented as an in-vehicle terminal 10, and the following process will be described with the in-vehicle terminal 10 as the execution subject.

[0016] Optionally, the vehicle terminal 10 can be implemented as at least one of a gasoline-powered vehicle, an electric vehicle, a hybrid vehicle, a fuel cell vehicle, or a solar-powered vehicle, wherein a hybrid vehicle refers to a combination of a gasoline-powered vehicle and an electric vehicle. In this embodiment, the vehicle terminal 10 is a vehicle equipped with an intelligent system, and the specific type of vehicle is not specifically limited.

[0017] Optionally, the vehicle terminal 10 includes a vehicle controller 100, a weather detection sensor 101, and a temperature and humidity sensor 102.

[0018] The vehicle controller 100 is located inside the vehicle terminal 10 and is an electronic computing unit used to monitor and control the operation of various systems of the vehicle terminal 10 in real time. The vehicle controller 100 is used to receive component data corresponding to at least one component within the vehicle terminal 10 to execute control algorithms and drive actuators, thereby realizing closed-loop management of the power, chassis, body, and energy functions of the vehicle terminal 10.

[0019] Optionally, the vehicle controller 100 communicates with at least one component in the vehicle terminal 10 via a bus such as the vehicle serial bus standard CAN (Controller Area Network), the vehicle serial bus standard LIN (Local Interconnect Network), or Ethernet.

[0020] In this embodiment, the vehicle controller 100 establishes a communication connection with the weather detection sensor 101 and the temperature and humidity sensor 102 to receive data sent by the weather detection sensor 101 and the temperature and humidity sensor 102. For specific connection methods, please refer to the connection methods described above.

[0021] Optionally, the weather detection sensor 101 is located outside the vehicle terminal 10. The weather detection sensor 101 is used to determine the weather conditions of the environment in which the vehicle terminal 10 is located, that is, to determine the external weather conditions, such as: rainy day, sunny day, cloudy day, etc.

[0022] Optionally, the weather detection sensor 101 collects weather environmental data of the environment in which the vehicle terminal 10 is located to identify the weather. Illustratively, the weather detection sensor collects weather environmental data to identify rainy, sunny, snowy, and cloudy weather.

[0023] In this embodiment, the weather detection sensor 101 is implemented as at least one of a rain sensor, a snow sensor, a snow depth sensor, a visibility sensor, a barometric pressure sensor, and a wind speed and direction sensor. For example, when the weather detection sensor 101 is implemented as a rain sensor, it collects the amount and intensity of rainfall in the external environment to identify whether the weather is rainy; when the weather detection sensor 101 is implemented as a snow sensor, it collects the amount and depth of snowfall in the external environment to identify whether the weather is rainy.

[0024] Optionally, the temperature and humidity sensor 102 is disposed outside the vehicle terminal 10. The temperature and humidity sensor 101 is used to detect the temperature and humidity of the external environment; that is, the temperature and humidity sensor 102 is an environmental sensor that simultaneously detects temperature and humidity. In the embodiments of this application, the temperature and humidity sensor 102 can be implemented as an integrated sensor that simultaneously detects temperature and humidity, or it can be implemented as a temperature sensor that independently detects temperature and a humidity sensor that independently detects humidity; this application does not limit this.

[0025] In this embodiment, the weather detection sensor 101 collects weather environment data of the external environment, generates a weather signal based on the weather environment data, and sends the weather signal to the vehicle controller 100.

[0026] After receiving the weather signal, the vehicle controller 100 determines the closed state of the door assembly inside the vehicle terminal 10. When the closed state indicator of the door assembly switches from the closed state to the open state (that is, corresponding to the door opening operation), it acquires the temperature and humidity data collected by the temperature and humidity sensor 102. The temperature and humidity data includes the temperature data and humidity data of the external environment.

[0027] The vehicle controller 100 determines the air output data of the air pump in the vehicle terminal 10 based on temperature data, humidity data and weather environment data, and controls the air pump outlet to output air based on the air output data.

[0028] Schematic illustration: Weather detection sensor 101 detects rainy weather and generates a rain signal based on rainfall data and rainfall intensity data, then sends the rain signal to vehicle controller 10. Vehicle controller 100 then determines the closed state of the door assembly. When the closed state indicates that the door assembly is switched from the closed state to the open state, it acquires temperature and humidity data collected by temperature and humidity sensor 102. Based on the temperature data, humidity data, rainfall data, and rainfall intensity, vehicle controller 100 determines the airflow data of the air pump and controls the airflow from the air pump outlet to match the aforementioned airflow data.

[0029] The above content involves an air pump. In this embodiment, the air pump is installed inside the vehicle terminal 10, and its air outlet is located above and below the door assembly. The air pump is connected to the air outlet through an air pipe and delivers air that meets the air outlet data to the air outlet according to the instructions of the vehicle controller 100, so as to balance the in-vehicle environment and the out-of-vehicle environment.

[0030] The above embodiments are only described from the perspective of implementation on one side of the vehicle terminal 10. The above process can also be implemented by the vehicle terminal 10 and the vehicle server. The vehicle terminal 10 sends the various data collected by its own components to the vehicle server, which performs logical operations to generate the final air outlet data and sends the air outlet data to the vehicle terminal 10. The vehicle terminal 10 then controls the air pump to work according to the air outlet data.

[0031] It should be noted that the information (including but not limited to weather and environmental data), data (including but not limited to data used for analysis, stored data, and displayed data), and signals involved in this application have all been authorized by the user or by all parties in full, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant regions. For example, the weather and environmental data, temperature and humidity data involved in this application were obtained with full authorization.

[0032] In this embodiment, a weather detection sensor monitors the weather conditions of the vehicle terminal's environment in real time. Based on the weather signal generated by the sensor, it is determined whether the vehicle door assembly is open. If the door is open, the airflow from the air pump vent is determined based on temperature, humidity, and weather data. This allows the airflow to automatically adapt to the external weather, improving the vehicle terminal's intelligence while preventing external environmental factors from affecting the interior environment, thus effectively enhancing the user's driving experience.

[0033] Based on the above, the control method of the vehicle terminal provided in the embodiments of this application will be described. Figure 2 This is a flowchart of a control method for an in-vehicle terminal provided in an exemplary embodiment of this application. In this embodiment, the method is executed by the in-vehicle controller, such as... Figure 2 As shown, the method includes the following steps.

[0034] Step 200: In response to receiving a weather signal from a weather detection sensor, determine the closed state of the door assembly inside the vehicle terminal.

[0035] Optionally, the vehicle terminal includes a vehicle controller, door components, an air pump, a weather detection sensor, and a temperature and humidity sensor.

[0036] The vehicle controller is located inside the vehicle terminal and is an electronic computing unit responsible for calculations.

[0037] The door assembly is a complete functional system that constitutes the vehicle terminal door. It includes a component assembly that realizes all functions such as opening, closing, sealing, and safety of the door. The door is an openable opening on the side of the vehicle terminal, providing a passage for the driver to enter and exit the vehicle terminal, while also undertaking functions such as structural support.

[0038] The air pump is a miniature pneumatic pump integrated inside the vehicle terminal, used to provide positive pressure airflow or negative pressure suction. The air pump is located above and / or below the side of the vehicle terminal; in this embodiment, the air pump is located above and / or below the door assembly.

[0039] A weather detection sensor is installed on the exterior of the vehicle terminal to detect the weather conditions in the external environment. In this embodiment, the weather detection sensor is installed on the top of the vehicle terminal. When the vehicle terminal is turned on, the weather detection sensor collects weather data of the external environment at preset intervals and generates a weather signal based on the weather data.

[0040] A temperature and humidity sensor is installed outside the vehicle terminal to detect the temperature and humidity of the external environment. When the vehicle terminal is turned on, the temperature and humidity sensor collects temperature and humidity data of the external environment at preset intervals. In this embodiment, the temperature and humidity sensor is implemented as a temperature sensor and a humidity sensor, with the temperature sensor collecting temperature data and the humidity sensor collecting humidity data.

[0041] In this embodiment, the vehicle controller establishes a communication connection with the door assembly, air pump, weather detection sensor, and temperature and humidity sensor.

[0042] In some embodiments, the process by which a weather detection sensor generates weather signals is described in detail below.

[0043] Optionally, the weather detection sensor collects weather environmental data of the external environment, including at least one of rainfall, rainfall intensity, snowfall, snow intensity, air pressure, wind direction, wind speed, and visibility.

[0044] In some embodiments, when the weather detection sensor is implemented as a rain sensor, the weather environmental data includes rainfall amount and rainfall intensity. Rainfall amount refers to liquid precipitation falling from the sky onto the vehicle terminal within a certain period of time; rainfall intensity refers to the amount of rainfall per unit time, representing the strength of precipitation, and is determined by the ratio of rainfall amount to rainfall duration. Optionally, rainfall intensity is divided into four levels: light rain, moderate rain, heavy rain, and torrential rain. Light rain refers to rainfall intensity less than 2.5 mm / h, moderate rain refers to rainfall intensity between 2.5 mm / h and 8 mm / h, heavy rain refers to rainfall intensity between 8 mm / h and 16 mm / h, and torrential rain refers to rainfall intensity greater than 16 mm / h. This classification is merely an example, and other ranges can also be used to classify rainfall intensity, which is not limited in this application.

[0045] In some embodiments, when the weather detection sensor is implemented as an ultrasonic snow depth timer, the weather environmental data includes snowfall amount and snowfall intensity. Snowfall amount refers to solid precipitation (snow) falling from the sky onto the vehicle terminal within a certain period of time; snowfall intensity refers to the amount of snowfall per unit time, representing the degree of snowfall strength, and is determined by the ratio of snowfall amount to snowfall duration. In another embodiment, snowfall intensity can also be determined by the snow depth change rate and the degree of snow accumulation density, which is not limited in this application. Optionally, snowfall intensity is divided into four levels of snowfall, including light snow, moderate snow, heavy snow, and blizzard. Light snow refers to snowfall intensity less than 1 mm / h, moderate snow refers to snowfall intensity between 1 mm / h and 3 mm / h, heavy snow refers to snowfall intensity between 3 mm / h and 5 mm / h, and blizzard refers to snowfall intensity greater than 5 mm / h. This classification is only an example, and snowfall intensity can also be classified in other ranges, which is not limited in this application.

[0046] In some embodiments, when the weather detection sensor is implemented as a barometric pressure sensor, the weather environmental data includes barometric pressure. Barometric pressure refers to the pressure exerted per unit area by the column of air in the atmosphere due to gravity.

[0047] In some embodiments, when the weather detection sensor is implemented as a wind direction and wind speed sensor, the weather environmental data includes wind direction and wind speed. Wind direction refers to the direction from which the wind blows, that is, the starting point of the airflow movement; wind speed refers to the distance that an air particle moves horizontally per unit time.

[0048] In some embodiments, when the weather detection sensor is implemented as a transmission instrument, the weather environmental data includes visibility. Visibility refers to the maximum horizontal distance at which a person with normal vision can see and identify an object against the sky background under the prevailing weather conditions.

[0049] In this embodiment, different weather detection sensors detect and identify different weather conditions. That is, a rain sensor is used to identify whether it is a rainy day, an ultrasonic snow depth meter is used to identify whether it is a snowy day, and a projector is used to identify whether it is a cloudy day.

[0050] In another optional embodiment, the various weather detection sensors described in the above embodiments can be freely combined to detect weather conditions such as rainy days, snowy days, cloudy days, and sunny days.

[0051] Optionally, after the weather detection sensor collects weather and environmental data, it generates a weather signal based on the weather and environmental data. The weather signal includes the weather type and the weather and environmental data.

[0052] In some embodiments, when the weather detection sensor is implemented as a rain sensor, the weather signal includes rainy day, rainfall amount, and rainfall intensity, such as: the weather signal includes rainy day, 10mm / 24h, and light rain. When the weather detection sensor is implemented as an ultrasonic snow depth meter, the weather signal includes snowy day, snowfall amount, and snowfall intensity, such as: the weather signal includes snowy day, 2.5mm / 24h, and light snow.

[0053] In some embodiments, it is determined whether the weather type in the weather signal matches the preset weather. If they match, the weather detection sensor sends the weather signal to the vehicle controller. If they do not match, the weather signal is deleted. The preset weather includes rainy days and snowy days.

[0054] Optionally, the closing status of the door assembly can be determined after receiving a weather signal.

[0055] The closed state refers to the situation where the door assembly is in the process of closing or after it is completely closed, and its locking structure and the body latch reach a specific engagement position. The closed state includes the open state and the closed state. The locking structure includes a ratchet with a toothed or hook-shaped structure on its outer edge, which is used to engage with the latch to achieve the step-by-step locking and holding of the door.

[0056] The following is an example illustrating the method for detecting the closed state of a car door assembly.

[0057] The first method is to identify the closed state through mechanical switch detection.

[0058] Optionally, the vehicle terminal includes a door contact switch. The door contact switch comprises a fixed contact located on the vehicle body or lock body, a movable contact on the door (moving with the door), and a spring return mechanism. The opening and closing of the mechanical contacts is used to detect whether the door is closed. When the door is closed, a striker or cam on the door presses the switch button, causing the contacts to open; when the door is opened, the spring releases, and the contacts close. That is, when an open contact is detected, the closed state is determined to be the closed state; when a closed contact is detected, the closed state is determined to be the open state.

[0059] The second method is to identify the closed state through magnetic detection.

[0060] Optionally, a Hall sensor is installed in the vehicle terminal to determine the door's closed state based on the signals collected by the Hall sensor. The Hall sensor includes a Hall element mounted on the lock body and a permanent magnet mounted on the door ratchet. When the ratchet rotates, the permanent magnet moves with it, and the Hall element detects the change in magnetic field strength. Different engagement positions correspond to different magnetic field strengths, which are used to determine the door's closed state.

[0061] Optionally, when the ratchet is fully open, the Hall element detects the first magnetic field strength and outputs a low level; when the ratchet is in a half-locked state, the Hall element detects the second magnetic field strength and outputs a medium level; when the ratchet is in a fully locked state, the Hall element detects the third magnetic field strength and outputs a high level, wherein the first magnetic field strength is less than the second magnetic field strength and the third magnetic field strength.

[0062] The third method is to identify the closed state through current detection.

[0063] Optionally, the locking motor of the vehicle terminal is equipped with an incremental encoder. The incremental encoder records the rotation angle of the locking motor, and the opening and closing angle of the door is determined by an angle mapping table, which is preset by technicians. The closed state of the door is determined based on the opening and closing angle.

[0064] The fourth method is to identify the closed state using ultrasonic detection.

[0065] Optionally, an ultrasonic sensor is installed in the B-pillar trim panel of the vehicle body. The ultrasonic sensor emits ultrasonic pulses to measure the distance from the door panel to the B-pillar of the vehicle body, and determines the closing state of the door assembly based on the distance.

[0066] Indicatively, when the distance is within the first range, the door assembly is determined to be in a closed state; when the distance is within the second range, the door assembly is determined to be in an open state. The first range is smaller than the second range, for example, the first range is 5-10mm and the second range is greater than 20mm.

[0067] The fifth method is to identify the closed state through image detection.

[0068] Optionally, the vehicle terminal is equipped with an image capturing component at the door assembly. The image capturing component captures images of the door gap, and the image processing algorithm is used to determine the closure status of the door assembly.

[0069] In some embodiments, the specific detection process is as follows: the image capturing component captures an image of the door gap; the image of the door gap is preprocessed (including noise reduction, enhancement, and other processing methods) to obtain a preprocessed image of the door gap. The contour of the door gap in the processed image is extracted using edge detection, and the width of the door gap is determined based on the contour. If the width is greater than a preset value, the door component is determined to be in an open state; if the width is less than or equal to the preset value, the door component is determined to be in a closed state. For illustration, the preset value is 0.

[0070] The above method is only an example. Other methods (such as optical detection methods, strain / stress detection methods, capacitance detection methods, etc.) can also be used to identify the closing state of the door assembly. This application does not limit the method in this regard.

[0071] Step 210: In response to the closed state indication, the door assembly switches from the closed state to the open state, and acquires the temperature and humidity data collected by the temperature and humidity sensor.

[0072] Optionally, the temperature and humidity sensor is used to detect the temperature and humidity of the environment in which the vehicle terminal is located. The temperature and humidity sensor can be implemented as an integrated sensor that integrates the detection of temperature and humidity, or it can be implemented as two independent sensors that detect temperature and humidity respectively. This application does not limit this.

[0073] In this embodiment of the application, the temperature and humidity sensor collects temperature and humidity data, which includes temperature data and humidity data.

[0074] In this embodiment of the application, the vehicle controller detects changes in the closing state of the door assembly, and acquires temperature and humidity data when the door assembly switches from the closed state to the open state.

[0075] Step 220: Based on temperature data, humidity data, and weather environment data, determine the air output data of the air pump in the vehicle terminal.

[0076] Optionally, the vehicle controller integrates temperature data, humidity data, and weather environment data, and uses a fuzzy logic algorithm to dynamically adjust the control commands to the air pump. That is, it combines temperature data, humidity data, and weather environment data to determine the air volume of the air pump outlet.

[0077] In this embodiment of the application, the airflow data is determined by the following method.

[0078] The first method is to determine this based on historical data.

[0079] Based on temperature data, humidity data, and weather data, the airflow data is determined from a preset historical data table.

[0080] The preset historical data table is a table built based on historical data.

[0081] Specifically, this involves: acquiring historical temperature and humidity data, as well as historical weather and environmental data, and acquiring historical air output data of the air pump corresponding to the historical temperature and humidity data and historical weather and environmental data.

[0082] Based on historical temperature data, historical humidity data, historical weather and environmental data, and historical airflow data, a preset historical data table is constructed, as shown in Table 1.

[0083] Table 1

[0084] The system retrieves historical airflow data from a preset historical data table that matches temperature, humidity, and weather data, and identifies this historical airflow data as the airflow data that the air pump will soon output.

[0085] In some embodiments, during the query process, it cannot be guaranteed that the corresponding historical air output data can be found in the preset historical data table for each set of data. Therefore, during the query process, the historical temperature data, historical humidity data, and historical weather environment data all have corresponding data error ranges. That is, as long as the above three data match the historical air output data within their respective allowable data error ranges, the historical air output data is determined as the air output data that the air pump will output.

[0086] Optionally, historical temperature data corresponds to a first error range, historical humidity data corresponds to a second error range, and historical weather data corresponds to a third error range. The first, second, and third error ranges can be the same or different, and this application does not limit this. For example, if a preset historical data table records {historical temperature data a, historical humidity data b, historical weather data c, and historical airflow data d}, and the currently collected temperature data A, humidity data B, and historical weather data C have a first error range of ±3, a second error range of ±4, and a third error range of ±5, then if temperature data A falls between [a-3, a+3], humidity data B falls between [b-4, b+4], and weather data C falls between [c-5, c+5], then historical airflow data d is determined as the airflow data that the air pump will output.

[0087] The second method is to determine it based on the corresponding level relationships.

[0088] Determine the environmental level corresponding to the weather data. The environmental level refers to the level corresponding to the current weather. The environmental level is set in advance by technical personnel. For example, the environmental level corresponding to rainy days is four levels: light rain, moderate rain, heavy rain, and rainstorm. The environmental level corresponding to snowy days is four levels: light snow, moderate snow, heavy snow, and blizzard.

[0089] Determine the temperature level corresponding to the temperature data. The temperature level refers to the temperature range corresponding to the current temperature. The higher the temperature level, the higher the temperature. The temperature level is preset by technicians. For example, the temperature level includes three levels: low temperature, normal temperature, and high temperature.

[0090] Determine the humidity level corresponding to the humidity data. The humidity level refers to the humidity range corresponding to the current humidity. The higher the humidity level, the higher the humidity. The humidity level is preset by technicians. For example, the humidity level includes low humidity, normal humidity and high humidity.

[0091] Based on the environmental level, temperature level, and humidity level, the airflow data is determined from the preset weather rule table, which is a table constructed based on historical data.

[0092] Specifically, this involves: acquiring historical temperature and humidity data, as well as historical weather and environmental data, and acquiring historical air output data of the air pump corresponding to the historical temperature and humidity data and historical weather and environmental data.

[0093] Historical temperature and humidity data are classified into multiple historical temperature levels and multiple historical humidity levels; historical weather and environmental data are also classified into multiple historical environmental levels.

[0094] Based on multiple historical humidity levels, multiple historical temperature levels, multiple historical environmental levels, and corresponding historical airflow data, a preset weather rule table is constructed. The preset weather rule table is shown in Table 2. The weather environmental data in Table 2 is illustrated using a rainy day scenario as an example.

[0095] Table 2

[0096] In another optional embodiment, historical wind data is also presented in the form of wind level. That is, in the process of constructing the preset weather rule table, the historical wind level will replace the historical wind data. The higher the wind level, the larger the wind data value. The wind level corresponds to the wind range, as shown in Table 3.

[0097] Table 3

[0098] The third method is to determine the airflow data based on the level and weighting relationship.

[0099] In an optional embodiment, the air volume of the air pump at the current moment is dynamically adjusted according to the level correspondence.

[0100] Obtain the real-time air output data of the air pump at the current moment.

[0101] Following the second method described above, the environmental level corresponding to the weather and environmental data is determined, and the environmental level corresponds to the first weight. The higher the environmental level, the higher the first weight.

[0102] Determine the temperature level corresponding to the temperature data. The temperature level corresponds to the second weight. The higher the temperature level, the lower the second weight.

[0103] Determine the humidity level corresponding to the humidity data. Each humidity level has a third weight, and the higher the temperature level, the higher the third weight.

[0104] In some embodiments, the environmental level corresponding to the weather environmental data and the first weight corresponding to the environmental level are determined according to a preset environmental level range; the temperature level corresponding to the temperature data and the second weight corresponding to the temperature level are determined according to a preset temperature level range; the humidity level corresponding to the humidity data and the third weight corresponding to the humidity level are determined according to a preset humidity level range, wherein the higher the environmental level, the higher the first weight; the higher the temperature level, the lower the second weight; and the higher the humidity level, the higher the third weight.

[0105] The real-time airflow data is adjusted according to the first, second, and third weights to obtain the final airflow data. In other words, the airflow data is determined based on the real-time airflow data, the first weight, the second weight, and the third weight.

[0106] In a schematic manner, the first product of the first weight and the real-time air outlet data is determined, the second product of the second weight and the real-time air outlet data is determined, and the third product of the third weight and the real-time air outlet data is determined. The sum of the first product, the second product and the third product is determined as the air outlet data.

[0107] The fourth method is to determine the airflow data based on the level and weighting relationship.

[0108] In an optional embodiment, a preset weather rule table records the degree of influence of weather environment data, temperature data, and humidity data on the air outlet data. This influence is presented in the form of weight values, which are set by relevant personnel according to the actual situation.

[0109] In a schematic manner, the first value and fourth weight corresponding to the weather environment data are determined from the preset weather rule table, the second value and fifth weight corresponding to the temperature data are determined, and the third value and sixth weight corresponding to the humidity data are determined.

[0110] Determine the fourth product of the first value and the fourth weight, the fifth product of the second value and the fifth weight, and the sixth product of the third value and the sixth weight. The sum of the fourth, fifth, and sixth products is determined as the air outlet data.

[0111] In another optional embodiment, before performing fusion calculations on the weather environment data, temperature data, and humidity data, it is necessary to perform noise reduction processing on the weather environment data, temperature data, and humidity data to obtain candidate weather environment data, candidate temperature data, and candidate humidity data. Subsequently, based on the candidate weather environment data, candidate temperature data, and candidate humidity data, the air outlet data is determined.

[0112] Denoising refers to the process of extracting effective signals and suppressing or eliminating noise components from noisy raw data using data algorithms or signal processing methods to improve data quality and usability. Common sources of noise include, but are not limited to, sensor errors, environmental fluctuations, transmission distortion, and quantization errors.

[0113] In the embodiments of this application, at least one of the following methods can be used to perform the above-mentioned denoising process: time-domain denoising method, frequency-domain denoising method, or Kalman filtering.

[0114] Temporal denoising methods include, but are not limited to, moving average filtering, median filtering, and weighted moving average. Moving average filtering replaces the current value with the average of neighboring data to smooth out random fluctuations. Median filtering replaces the current value with the median of the neighborhood data. Weighted moving average assigns different weights to data at different times, with more recent data points receiving higher weights.

[0115] Frequency domain denoising methods include, but are not limited to, low-pass filtering, high-pass filtering, band-pass filtering, band-stop filtering, and fast Fourier transform (FFT) filtering. Low-pass filtering allows low-frequency signals to pass through while attenuating high-frequency noise. High-pass filtering removes low-frequency offsets. Band-pass filtering preserves a specific frequency band. Band-stop filtering eliminates specific frequencies. Fast Fourier transform (FFT) filtering involves performing a Fourier transform on the time-domain signal to convert it into a frequency spectrum, applying frequency thresholding for denoising, and then performing an inverse Fourier transform to convert it back to the time-domain signal.

[0116] Kalman filtering is a denoising process based on a pre-defined state-space model, integrating prediction and observation. It sets up state equations that include process noise and observation noise, and uses the collected data, process noise, and observation noise to perform predictions (predicting current data based on the model) and updates (correcting predictions with actual observations).

[0117] The above denoising process is consistent with the denoising process mentioned in the prior art, and will not be repeated here.

[0118] Step 230: Control the air pump outlet to discharge air based on the air discharge data.

[0119] Optionally, after determining the air output data, the air pump's outlet is controlled to output air according to the air output data.

[0120] To illustrate, after determining the airflow data, the vehicle controller generates an airflow adjustment signal, which includes the airflow data. The airflow adjustment signal is then sent to the air pump, which receives the signal and adjusts the airflow according to the data indicated in the signal.

[0121] In an optional embodiment, the air pump can adaptively adjust the airflow strength according to the opening and closing angle of the door assembly while discharging air according to the airflow data.

[0122] In this embodiment of the application, the opening and closing angle of the door assembly is determined. The opening and closing angle can be determined by any of the methods used in the above embodiments to determine the closed state of the door assembly, which will not be elaborated here.

[0123] In response to the opening and closing angle meeting the first threshold range, the air outlet of the control air pump is controlled to discharge air based on the first air discharge data.

[0124] Among them, the first air outlet data is greater than the air outlet data.

[0125] In response to the opening and closing angle meeting the second threshold range, the air outlet of the control air outlet is lowered at a constant speed to the air outlet data at the first air outlet data.

[0126] In response to the opening and closing angle meeting the third threshold range, the air outlet is controlled to discharge air based on the second air discharge data, where the second air discharge data is less than the air discharge data.

[0127] Among them, the first threshold range is less than the second threshold range, which is less than the third threshold range.

[0128] In another optional embodiment, in response to the opening angle meeting the first threshold range, the air outlet of the air pump is controlled to discharge air based on the air discharge data. As the opening angle increases, the air discharge volume of the air pump gradually decreases until the air discharge volume decreases to the first preset air discharge threshold. When the air discharge volume decreases to the first preset air discharge threshold, it means that the door assembly is fully opened.

[0129] In another alternative embodiment, in response to the opening angle meeting the first threshold range, the air volume of the air pump outlet is controlled to gradually increase from the second preset air volume threshold to the air volume data. When the air volume increases to the air volume data, it means that the door assembly is fully opened.

[0130] In this embodiment of the application, during the process of dynamically adjusting the air pump output volume, the data collected by the weather detection sensor is verified in conjunction with the weather information sent by the server to ensure that the above dynamic adjustment process is applied when the external environment is in a special weather scenario.

[0131] Optionally, weather information can be obtained from the vehicle-mounted server. The vehicle-mounted server maintains a communication connection with the weather system. When the vehicle terminal is turned on, the vehicle-mounted server automatically sends the weather information obtained from the weather system to the vehicle terminal. The weather information includes the primary weather type, such as: sunny, rainy, snowy, windy, etc.

[0132] Optionally, the weather information may also include the intensity of the first weather type, such as: the weather information includes rain and rainfall intensity, snow and snowfall intensity, or strong wind and wind intensity, etc.

[0133] In this embodiment of the application, the first weather type includes rainy days and snowy days.

[0134] In response to the weather environment data collected by the weather detection sensor matching the first weather type, the system generates and displays the first prompt information, and then controls the air pump to work according to the air output data.

[0135] The first prompt message is used to indicate that the external environment is in special weather conditions and that the air pump needs to balance the external environment and the in-vehicle environment. The first prompt message can be implemented as at least one of the following: text information, video information, audio information, and image information.

[0136] Indicatively, when the weather detection sensor is implemented as a rain sensor, if the rainfall collected by the rain sensor is not 0 and the rainfall is consistent with the first weather intensity data recorded in the first weather type, it is determined that the weather environment data matches the first weather type.

[0137] Indicatively, when the weather detection sensor is implemented as an ultrasonic snow depth meter, and the snowfall collected by the ultrasonic snow depth meter is not zero and the snowfall is consistent with the first weather intensity data recorded in the first weather type, it is determined that the weather environment data matches the first weather type.

[0138] As an illustration, the first prompt is displayed as the text message: "The current weather is rainy. The air pump needs to be dynamically adjusted. Please be careful when opening the car door!"

[0139] In a demonstrative manner, the first prompt is implemented as video information, including a 3D model of the in-vehicle terminal. Above the 3D model are demonstration particles simulating the weather indicated by the first weather type. For example, if the current weather is rainy, demonstration particles simulating rain will appear above the 3D model. Optionally, the number of demonstration particles can be dynamically adjusted according to the intensity of the first weather type; the higher the intensity, the more demonstration particles. The video information also displays images corresponding to the first weather type, allowing in-vehicle users to easily understand the current weather at a glance.

[0140] In a schematic manner, the first prompt is implemented as audio information, which includes audio content indicating the current weather type, such as: "The current weather is rainy, please be careful when opening the car door." In an optional embodiment, the voice information of the in-vehicle user is acquired, and the voice characteristics of the voice information are analyzed, including timbre, pitch, etc. Audio information is generated based on the voice characteristics, simulating the voice of the in-vehicle user to provide a prompt.

[0141] In response to a mismatch between the weather environment data collected by the weather detection sensor and the first weather type, a second prompt message is generated and displayed. Subsequently, the air pump is controlled to operate according to the current airflow. The second prompt message is used to indicate that the external environment is in normal weather and that the air pump does not need to balance the external environment and the in-vehicle environment. The second prompt message can be implemented as at least one of the following: text information, video information, audio information, and image information.

[0142] For illustrative purposes, when the weather detection sensor is implemented as a rain sensor, if the rainfall collected by the rain sensor is 0 or the rainfall is inconsistent with the first weather intensity data recorded in the first weather type, it is determined that the weather environment data does not match the first weather type.

[0143] For illustrative purposes, when the weather detection sensor is implemented as an ultrasonic snow depth meter, if the snowfall collected by the ultrasonic snow depth meter is 0 or the snowfall is inconsistent with the first weather intensity data recorded in the first weather type, it is determined that the weather environment data does not match the first weather type.

[0144] For illustrative purposes, the first prompt message is implemented as the text message "The current weather is sunny (the weather here is determined according to the weather indicated by the first weather type)".

[0145] Indicatively, the first prompt is implemented as video information, which includes a 3D model of the vehicle terminal and demonstration particles above the 3D model simulating the weather indicated by the first weather type, such as: if the current weather is sunny, demonstration particles above the 3D model simulating sunlight.

[0146] In a schematic manner, the first prompt is implemented as audio information, which includes audio content indicating the current weather type, such as "The current weather is sunny." In an optional embodiment, the voice information of the in-vehicle user is acquired, and the sound characteristics of the sound information are analyzed, including timbre, pitch, etc. Audio information is generated based on the sound characteristics, simulating the voice of the in-vehicle user to provide a prompt.

[0147] In this embodiment, a weather detection sensor monitors the weather conditions of the vehicle terminal's environment in real time. Based on the weather signal generated by the sensor, it is determined whether the vehicle door assembly is open. If the door is open, the airflow from the air pump vent is determined based on temperature, humidity, and weather data. This allows the airflow to automatically adapt to the external weather, improving the vehicle terminal's intelligence while preventing external environmental factors from affecting the interior environment, thus effectively enhancing the user's driving experience.

[0148] Based on the above, the control method of the vehicle terminal provided in the embodiments of this application will be described. Figure 3 This is a schematic diagram of the control system of an in-vehicle terminal provided in another exemplary embodiment of this application. In this embodiment, the control method of the in-vehicle terminal can be applied to rainy weather scenarios, and the weather detection sensor is implemented as a rain sensor. The system includes a rain sensor 30, a door lock 31, an anemometer 32, a temperature sensor 33, a humidity sensor 34, an in-vehicle controller 35, and an air pump 36.

[0149] Rain sensor 30 is installed on the top of the vehicle terminal to ensure that rain can be detected. Rain sensor 30 is connected to vehicle controller 35 through signal line and transmits the detected rain signal to vehicle controller 35. The rain signal includes rain, rainfall amount and rainfall intensity.

[0150] The door lock 31 is installed on the door assembly and is connected to the vehicle controller 35 via a signal line. The door lock 31 is monitored in real time for its closed state, which includes both open and closed states.

[0151] Anemometer 32 is installed at any location outside the vehicle terminal, such as on the roof rack. Anemometer 32 transmits the measured wind speed data to the vehicle controller 35 via a signal cable.

[0152] Temperature sensor 33 is installed outside the vehicle terminal to measure the current ambient temperature and output the measured temperature data to the vehicle controller 35.

[0153] A humidity sensor 34 is installed above and / or below the side door to detect the humidity in the area above and below the side door in real time and to feed the humidity data back to the vehicle controller 35.

[0154] The vehicle controller 35 receives rain signals from the rain sensor 30, wind speed data from the anemometer 32, temperature data from the temperature sensor 33, humidity data from the humidity sensor 34, and the door lock's self-closing status, and performs data fusion and judgment. Based on a preset fuzzy logic algorithm (the specific details of this algorithm are described in the following embodiments), and combining rainfall, rainfall intensity, wind speed, temperature, and humidity, it calculates the predetermined air volume that the air pump needs to output, and dynamically adjusts the control commands to the air pump 36.

[0155] An air pump 36 is installed inside the vehicle terminal, with its air outlet located above and / or below the side door. The air pump is connected to the air outlet via an air pipe and outputs air to the air outlet according to the control command sent by the vehicle controller 35 to blow away the rainwater above and / or below the side door.

[0156] The vehicle terminal control system provided in this application embodiment can automatically and accurately remove rainwater above and / or below the car door when the vehicle terminal is used on a rainy day, providing users with a better driving experience. For example, when a user is about to open the car door on a rainy day, the system will intelligently adjust the air pump output according to the current environmental information to ensure that the rainwater above and / or below the car door is effectively removed, so that the user can comfortably enter and exit the car without getting wet.

[0157] Based on the above, the control method of the vehicle terminal provided in the embodiments of this application will be described. Figure 4 This is a schematic diagram of the control system of an in-vehicle terminal provided in another exemplary embodiment of this application. In this embodiment, the control method of the in-vehicle terminal can be applied to snowy weather scenarios, and the weather detection sensor is implemented as a rain sensor. The system includes an ultrasonic snow depth gauge 40, a door assembly 41, an anemometer 42, a temperature sensor 43, a humidity sensor 44, an in-vehicle controller 45, and an air pump 46.

[0158] An ultrasonic snow depth meter 40 is installed on the top of the vehicle terminal to ensure that snowflakes can be detected. The ultrasonic snow depth meter 40 is connected to the vehicle controller 35 through a signal line and transmits the detected snow weather signal to the vehicle controller 45. The snow weather signal includes snow weather, snowfall amount, and snowfall intensity.

[0159] The door lock 41 is installed on the door assembly and is connected to the vehicle controller 45 via a signal line. The closing state of the door lock 41 is detected in real time, including the open state and the closed state.

[0160] Anemometer 42 is installed at any location outside the vehicle terminal, such as on the roof rack. Anemometer 42 transmits the measured wind speed data to the vehicle controller 45 via a signal cable.

[0161] Temperature sensor 43 is installed outside the vehicle terminal to measure the current ambient temperature and output the measured temperature data to the vehicle controller 45.

[0162] Humidity sensor 44 is located above and / or below the side door to detect the humidity in the area above and below the side door in real time and to feed the humidity data back to the vehicle controller 45.

[0163] The vehicle controller 45 receives rain signals from the ultrasonic snow depth meter 40, wind speed data from the anemometer 42, temperature data from the temperature sensor 43, humidity data from the humidity sensor 44, and the door lock's self-closing status, and performs data fusion and judgment. Based on a preset fuzzy logic algorithm (see the following embodiment for details of this algorithm), combined with snowfall, snowfall intensity, wind speed, temperature, and humidity, it calculates the predetermined air volume that the air pump needs to output, and dynamically adjusts the control commands to the air pump 36.

[0164] An air pump 46 is installed inside the vehicle terminal, with its air outlet located above and / or below the side door. The air pump is connected to the air outlet via an air pipe and outputs air to the air outlet according to the control command sent by the vehicle controller 45 to blow away the snowflakes above and / or below the side door.

[0165] The vehicle terminal control system provided in this application embodiment can automatically and accurately remove snowflakes above and / or below the car door when the vehicle terminal is used on a snowy day, providing users with a better driving experience. For example, when a user is about to open the car door on a snowy day, the system will intelligently adjust the air pump's output volume according to the current environmental information to ensure that the snowflakes and snow water above and / or below the car door are effectively removed, allowing users to comfortably enter and exit the car without being affected by snowflakes and snow water.

[0166] Based on the above, the control method of the vehicle terminal provided in the embodiments of this application will be described. Figure 5 This is a flowchart of a control method for an in-vehicle terminal provided in another exemplary embodiment of this application. The method is executed by the in-vehicle controller and is applied to rainy weather scenarios, such as... Figure 5 As shown, the method includes the following steps.

[0167] Step 500: Acquire sensor data collected by multiple sensors.

[0168] Optional, multiple sensors include a rain sensor, an anemometer, a temperature sensor, and a humidity sensor.

[0169] Among them, the rain sensor is used to identify whether it is raining in the external environment. When rain is detected, the rain sensor will not only send a rain signal to the vehicle controller, but also output the set rainfall intensity according to the rainfall amount. That is, the rain sensor generates a rain signal based on the collected data. The rain signal includes the rain signal and the rainfall intensity.

[0170] The anemometer is used to measure the wind speed in the current environment and send the measured wind force data to the vehicle controller.

[0171] The temperature sensor is used to measure the current ambient temperature and send the measured temperature data to the vehicle controller.

[0172] The humidity sensor is used to measure the humidity of the current environment and send the measured humidity data to the vehicle controller.

[0173] In this embodiment of the application, rain signals, wind speed data, temperature data, and humidity data are received.

[0174] Optionally, the door lock's closed state can be obtained. When the door lock switches from the closed state to the open state, the door lock generates an opening signal and sends the opening signal to the vehicle controller.

[0175] Step 510: Integrate sensor data collected from multiple sensors and use a fuzzy logic algorithm to dynamically adjust the control commands to the air pump.

[0176] Optionally, upon receiving the door opening signal from the car door lock, the rain signal, wind force data, temperature data, and humidity data are processed to remove noise and outliers, resulting in candidate rain signals, candidate wind force data, candidate temperature data, and candidate humidity data.

[0177] The rainfall in the candidate rainy day signal is divided into at least 3 fuzzy intervals, as follows.

[0178] The universe of discourse for rainfall is defined as \(R=[0,R_{max}]\), where \(R_{max}\) is the maximum rainfall that a rain sensor can detect.

[0179] Define the fuzzy sets: light rain (\(S\)), medium rain (\(M\)), and heavy rain (\(L\)).

[0180] Define membership function: Light rain: \(\mu_{S}(r)=\begin{cases}1,&r\leqr_{1}\\ \frac{r_{2}-r}{r_{2}-r_{1}},&r_{1} <r<r_{2}\\0,&r\geq r_{2}\end{cases}\)。

[0181] Moderate rain: \(\mu_{M}(r)=\begin{cases}0,&r\leq r_{1}\text{or}r\geq r_{3}\\ \frac{r - r_{1}}{r_{2}-r_{1}},&r_{1} <r<r_{2}\\ \frac{r_{3}-r}{r_{3}-r_{2}},&r_{2}\leq r<r_{3}\end{cases}\)。

[0182] heavy rain: \(\mu_{L}(r)=\begin{cases}0,&r\leq r_{2}\\ \frac{r_r_{2}}{r_{3}-r_{2}},&r_{2} <r<r_{3}\\ 1,&r\geq r_{3}\end{cases}\)。

[0183] Where \(r_{1}\), \(r_{2}\), and \(r_{3}\) are rainfall thresholds determined based on actual conditions, and the methods for wind speed, temperature, and humidity are the same as for rainfall.

[0184] Create a fuzzy rule table, as shown in Table 4 below.

[0185] Table 4

[0186] Based on the above membership function settings, the rainfall level corresponding to the rainfall amount in the candidate rainy day signal is determined, the wind speed level corresponding to the candidate wind speed data is determined, the temperature level corresponding to the candidate temperature data is determined, and the humidity level corresponding to the candidate humidity data is determined.

[0187] The predetermined air volume level corresponding to the rainfall level, wind speed level, temperature level and humidity level is determined from the fuzzy rule table. Control commands are generated based on the predetermined air volume level and sent to the air pump.

[0188] Step 520: Control the air pump to output the predetermined air volume according to the control command.

[0189] In the embodiments of this application, the control commands are executed in stages.

[0190] This is an illustrative example of using different control commands at different opening angles of the car door. For instance, at the moment the door begins to open, the air pump operates at maximum airflow to quickly blow away most of the rainwater; during the opening process, the air pump's output airflow is dynamically adjusted according to the predetermined airflow calculated above to save energy; after the door is fully open, the air pump maintains a smaller airflow to keep the area above and / or below the side door dry.

[0191] In this embodiment, a weather detection sensor monitors the weather conditions of the vehicle terminal's environment in real time. Based on the weather signal generated by the sensor, it is determined whether the vehicle door assembly is open. If the door is open, the airflow from the air pump vent is determined based on temperature, humidity, and weather data. This allows the airflow to automatically adapt to the external weather, improving the vehicle terminal's intelligence while preventing external environmental factors from affecting the interior environment, thus effectively enhancing the user's driving experience.
