[0043] 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.

[0044] The following description, with reference to the accompanying drawings, describes a method, apparatus, electronic device, and storage medium for controlling the interior temperature of a vehicle when the window is open, according to embodiments of this application.

[0045] Figure 1 This is a schematic flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, according to an embodiment of this application. Figure 1 As shown, the method includes:

[0046] S101 is the airflow parameter when air flows from outside the vehicle into the vehicle when the windows are open.

[0047] In practice, people have needs regarding the user experience when driving and riding in vehicles. For example, in the hot summer, people will turn on the air conditioning in the vehicle for cooling, and in the cold winter, people will turn on the air conditioning in the vehicle for heating.

[0048] When people turn on the air conditioning to adjust the temperature inside the vehicle, they close the windows, making it easier to regulate the temperature inside the vehicle.

[0049] In some scenarios, when a vehicle's windows are closed and the air conditioning is on for cooling and / or heating, the properties of objects inside the vehicle or the actions of occupants may cause unpleasant odors to develop inside. In such cases, people can choose to temporarily open a window to exchange the air inside the vehicle with the outside air for a short period, thereby improving the air quality inside the vehicle.

[0050] In other scenarios, when a vehicle's windows are closed and the air conditioning is on for cooling and / or heating, occupants may need to communicate with the outside world or perform other actions. In this scenario, people can choose to temporarily open a window to meet their needs.

[0051] Furthermore, when people open car windows, the inflow of outside air into the vehicle may have a certain impact on the interior temperature.

[0052] In this embodiment, the air flowing into the vehicle from outside when the window is opened has relevant attribute parameters, which can be determined as the airflow parameters of the air flowing into the vehicle from outside when the window is opened. These airflow parameters may include the airflow dynamics, static pressure, dynamic pressure, total pressure, etc.

[0053] Optionally, relevant calculations can be used to obtain the airflow parameters of the air flowing into the vehicle from outside when the windows are opened.

[0054] Optionally, a measuring device can be installed on the vehicle to obtain the airflow parameters of the air flowing into the vehicle from outside when the windows are opened.

[0055] S102 determines the rate of temperature change inside the vehicle based on airflow parameters and heat exchange area.

[0056] In practice, when outside air flows into the vehicle through an open window, the temperature inside the vehicle will change to some extent.

[0057] For example, in the hot summer, when the air conditioning is on inside a vehicle, the outside air temperature is higher than the inside air temperature. In this scenario, as hot outside air flows into the car through the open window, the interior temperature will rise at a certain rate due to the influx of hot outside air.

[0058] For example, in cold winter weather, when the vehicle's heating function is on, the outside air temperature is lower than the inside air temperature. In this scenario, as cold outside air flows into the vehicle through the open windows, the interior temperature will decrease at a certain rate due to the influx of cold outside air.

[0059] In this embodiment, the degree to which the outside air temperature affects the inside air temperature when the vehicle window is open is related to the airflow parameters of the air flowing into the vehicle and the heat exchange area of ​​the vehicle.

[0060] The heat exchange area inside a vehicle can be understood as the area of ​​people and / or objects inside the vehicle that exchange heat with the air when the windows are open. Furthermore, different heat exchange areas result in different parameters related to heat exchange, leading to varying degrees of temperature change inside the vehicle.

[0061] Furthermore, when outside air flows into the car through an open window, the temperature inside the car changes at a certain rate, which can be defined as the rate of temperature change inside the car when the window is open.

[0062] Optionally, the rate of temperature change inside the vehicle when the windows are open can be further calculated using the airflow parameters and heat exchange area corresponding to the opening of the vehicle windows.

[0063] Optionally, a corresponding temperature sensor can be installed on the vehicle to obtain the rate of temperature change inside the vehicle when the windows are opened, based on the detection results of the temperature sensor and the time corresponding to the temperature change process.

[0064] S103 determines the predicted interior temperature of the vehicle when the windows are open, based on the rate of temperature change.

[0065] In the real-time example of this application, the relevant parameters of the air inside the vehicle after the temperature change can be predicted based on the rate of change of the vehicle's interior temperature when the windows are opened.

[0066] Among them, the system can perform further calculations based on the obtained temperature change rate and the current in-vehicle temperature, thereby predicting the temperature that the air in the vehicle may reach within a set time, and determining the predicted result as the predicted in-vehicle temperature when the vehicle windows are open.

[0067] The method for predicting in-vehicle temperature when windows are open, as proposed in this application, acquires airflow parameters corresponding to the airflow entering the vehicle from outside when the windows are opened, and obtains the rate of temperature change inside the vehicle when the windows are opened based on the airflow parameters and the heat exchange area. Furthermore, based on the rate of temperature change, the predicted temperature inside the vehicle when the windows are open is determined. This application improves the accuracy of the predicted in-vehicle temperature by using airflow parameters and relevant heat exchange parameters when the windows are opened, thus providing support for precise temperature regulation inside the vehicle and avoiding temperature fluctuations when windows are opened, thereby optimizing the comfort of vehicle occupants.

[0068] In the above embodiments, the acquisition of the predicted temperature inside the vehicle can be combined with... Figure 2 To understand further, Figure 2 This is a flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, according to another embodiment of this application. Figure 2 As shown, the method includes:

[0069] S201, the calculation cycle for obtaining the target output temperature.

[0070] In practice, based on the rate of temperature change inside the vehicle when the windows are opened and the vehicle's interior temperature when the windows are opened, the interior temperature after the temperature change can be predicted and determined as the predicted interior temperature.

[0071] Optionally, an in-vehicle predicted temperature calculation unit can be set in the vehicle's temperature control system. The rate of change of the in-vehicle temperature and the current in-vehicle temperature are input into the calculation unit, and the predicted in-vehicle temperature is obtained based on the calculation results of the unit.

[0072] The calculation cycle of this calculation unit can be determined as the calculation cycle for predicting the in-vehicle temperature.

[0073] It should be noted that calculating the predicted temperature inside the vehicle involves a calculation process, which takes time. Therefore, in order to achieve timely adjustment and control of the temperature inside the vehicle, the operating cycle of the calculation unit can be set separately from the operating cycles of other functional units of the temperature control system, thereby shortening the operating cycle of the calculation unit.

[0074] S202, obtain the ratio of the rate of temperature change to the calculation cycle, and determine the sum of the ratio and the interior temperature of the vehicle when the window is open as the predicted interior temperature of the vehicle when the window is open.

[0075] In this embodiment of the application, the ratio of the rate of temperature change when the vehicle window is opened to the calculation period can be calculated. This ratio is the change value of the vehicle interior temperature within the calculation period. By using this change value and the vehicle interior temperature value when the window is opened, the possible value that the vehicle interior temperature may reach when the window is opened can be predicted.

[0076] Furthermore, the predicted temperature inside the vehicle is the output value of the computing unit in the next calculation cycle, and the predicted temperature inside the vehicle can be obtained by the following formula:

[0077] t 车内预测 =t 车内当前 +t 变化

[0078] In the above formula, t 车内预测 To predict the interior temperature of a vehicle when the windows are open, t 车内当前 The current temperature inside the vehicle when the windows are open, t 变化 This represents the change in vehicle interior temperature during the calculation cycle when the vehicle windows are open.

[0079] It should be noted that when the unit of measurement for the rate of change of the vehicle interior temperature in the above formula is ℃ / s, the calculation unit will convert the unit of measurement for the rate of change of the vehicle interior temperature to ℃ / ms when calculating the predicted temperature inside the vehicle. In this scenario, the operating cycle of other functional units of the temperature control system is in seconds, while the operating cycle of the unit calculating the predicted temperature inside the vehicle is in milliseconds.

[0080] The method for predicting the interior temperature of a vehicle when the window is open, as proposed in this application, obtains the calculation cycle for the predicted interior temperature and, based on the rate of temperature change and the calculation cycle, obtains the change value of the interior temperature when the window is open, thereby acquiring the predicted interior temperature when the window is open. In this application, obtaining the predicted interior temperature based on the calculation cycle and the rate of temperature change improves the accuracy of the obtained predicted interior temperature, thus enabling precise adjustment of the interior temperature when the window is open and optimizing the driving experience for vehicle users.

[0081] In the above embodiments, the rate of temperature change inside the vehicle when the windows are opened can be obtained by combining... Figure 3 To understand further, Figure 3 This is a flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, according to another embodiment of this application. Figure 3 As shown, the method includes:

[0082] S301 determines the heat exchange efficiency inside the vehicle when the windows are open, based on airflow parameters and heat exchange area.

[0083] In this embodiment of the application, the temperature change inside the vehicle when the windows are open can be obtained based on the heat exchange efficiency inside the vehicle, wherein the heat exchange efficiency can be obtained based on the heat exchange coefficient and heat exchange area inside the vehicle.

[0084] Furthermore, the heat transfer coefficient can be understood as the set coefficient that causes the temperature change inside the vehicle due to the airflow into the vehicle when the window is opened. Therefore, based on the airflow parameters of the airflow from outside the vehicle into the vehicle when the window is opened, the heat transfer coefficient inside the vehicle when the window is open can be obtained.

[0085] Among them, the airflow velocity from outside the vehicle to the vehicle when the window is opened can be obtained from the airflow parameters, and the heat transfer coefficient when the window is opened can be obtained based on the airflow velocity.

[0086] Optionally, adjusting the interior temperature when the vehicle windows are open can prevent the driver and passengers from perceiving temperature fluctuations that could reduce their comfort. Therefore, when adjusting the temperature when the vehicle windows are open, the primary focus should be on regulating the perceived temperature by the driver and passengers.

[0087] Furthermore, the setting parameters of the heat exchange object inside the vehicle can be obtained, wherein the setting parameters are determined based on the height and mass of the heat exchange object inside the vehicle.

[0088] In this embodiment of the application, the volume of the heat exchange object inside the vehicle when the window is open has a certain influence on the calculation of the heat transfer coefficient when the window is open. Optionally, the volume of the heat exchange object and the heat transfer coefficient can be positively correlated. Therefore, the volume of the heat exchange object inside the vehicle can be converted into a relevant set parameter so that it can participate in the calculation of the heat transfer coefficient.

[0089] In some implementations, the heat exchange target inside the vehicle can be the driver and / or passengers. The set parameters for the human body are related to the person's height and weight. For example, for a person who is 170 cm tall and weighs 65 kg, the set parameter can be 18.3.

[0090] Furthermore, the heat transfer coefficient can be obtained based on the airflow velocity and related human body parameters in the airflow parameters.

[0091] Optionally, the heat transfer coefficient inside the vehicle when the windows are open can be determined by multiplying the set parameters and the airflow velocity. The formula for calculating the heat transfer coefficient is as follows:

[0092] hc = B × V × n

[0093] In the above formula, hc is the heat transfer coefficient, V is the airflow velocity, n is the airflow velocity index, and B is a set parameter for the human body. Parameter B can be set based on the height and weight of the vehicle driver and / or passengers.

[0094] It should be noted that the settings parameters for vehicle drivers and / or passengers can be adjusted based on the different height and weight of the vehicle drivers and / or passengers.

[0095] Furthermore, the heat exchange efficiency inside the vehicle when the windows are open is determined based on the heat transfer coefficient and heat transfer area.

[0096] In this embodiment of the application, the degree of temperature change inside the vehicle when the window is opened is related to the heat exchange area to a certain extent, wherein the heat exchange area can be the area of ​​the heat exchange zone.

[0097] Optionally, in scenarios where the temperature is adjusted based on the perceived temperature of the vehicle's driver and / or passengers, the heat exchange area inside the vehicle can be understood as the surface area of ​​the skin of the vehicle's driver and / or passengers in contact with the air inside the vehicle.

[0098] The heat exchange area that the driver and / or passengers can exchange heat with when the vehicle windows are open can be represented by the following formula:

[0099]

[0100] Among them, S 换热 S represents the heat exchange area for the driver and / or passengers of the vehicle. 总 S is the total surface area of ​​the vehicle's driver and / or passengers. 着衣 S represents the clothing area of ​​the vehicle's driver and / or passengers. 裸露 The area of ​​exposed skin in contact with the air for the driver and / or passengers of a vehicle.

[0101] It should be noted that the total surface area of ​​the vehicle's driver and / or passengers can be determined based on relevant parameters such as height and weight.

[0102] Furthermore, the temperature difference between the inside and outside of the vehicle is obtained.

[0103] In this embodiment, a corresponding temperature sensor can be configured for the vehicle. When the vehicle window is open, the temperature sensor can collect temperature information outside and inside the vehicle and transmit it to the vehicle's control system.

[0104] Therefore, based on the vehicle's control system, temperature data collected by temperature sensors can be obtained, thereby determining the temperature difference between the inside and outside of the vehicle.

[0105] Furthermore, the heat exchange efficiency inside the vehicle when the windows are open is determined based on the product of the temperature difference, heat transfer coefficient, and heat transfer area.

[0106] In this embodiment of the application, the heat exchange efficiency inside the vehicle when the windows are open can be obtained according to the set calculation formula for heat exchange efficiency, wherein the formula is as follows:

[0107] q = hc × S 换热 (t 车外 -t 车内 )

[0108] In the above formula, q is the heat exchange efficiency inside the vehicle when the windows are open, hc is the heat transfer coefficient, and S... 换热 For heat exchange area, t 车外 The outside temperature when the vehicle windows are open, t 车内 The temperature inside the vehicle when the windows are open.

[0109] S302, based on heat exchange efficiency, determines the rate of temperature change inside the vehicle when the windows are opened.

[0110] In practice, the heat exchange efficiency inside a vehicle when the windows are open has a certain impact on the rate of temperature change inside the vehicle. Specifically, the heat exchange efficiency and the rate of temperature change inside the vehicle can show a positive correlation.

[0111] Furthermore, the product of the specific heat capacity and mass of the heat exchange objects inside the vehicle when the windows are open can be obtained. Based on the ratio of the heat exchange efficiency to the product value, the rate of temperature change inside the vehicle when the windows are open can be determined.

[0112] In this embodiment of the application, the rate of temperature change inside the vehicle when the window is opened is related to the specific heat capacity and mass of the heat exchange object inside the vehicle to a certain extent. Therefore, calculations are performed based on the relationship between these parameters to determine the rate of temperature change inside the vehicle when the window is opened.

[0113] Optionally, when the heat exchange targets inside the vehicle are the driver and / or passengers, the rate of temperature change inside the vehicle can be obtained based on the following formula:

[0114]

[0115] In the above formula, v 变化 The rate of change in temperature perceived by the driver and / or passengers when the vehicle windows are open; q is the heat exchange efficiency inside the vehicle; C p M represents the specific heat capacity of the human body, and M represents the mass of the human body.

[0116] The method for predicting in-vehicle temperature when windows are open, as proposed in this application, obtains the heat exchange efficiency of the vehicle interior when windows are open based on the airflow parameters flowing into the vehicle and the heat exchange area inside the vehicle. Furthermore, it determines the rate of temperature change inside the vehicle when windows are open based on this heat exchange efficiency. This accurate rate of temperature change provides a data foundation for subsequent temperature regulation inside the vehicle, enabling accurate and stable temperature control.

[0117] In the above embodiments, the acquisition of airflow parameters can be combined with... Figure 4 To understand further, Figure 4 This is a flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, as described in another embodiment of this application. Figure 4 As shown, the method includes:

[0118] S401, obtain the window opening area and vehicle speed when the vehicle window is open.

[0119] When a vehicle window is open, the airflow parameters that correspond to the airflow entering the vehicle from outside are related to the window area and the vehicle's speed.

[0120] In this embodiment, the corresponding window area can be obtained based on the opening ratio and corresponding window area of ​​each vehicle window. The window area of ​​each window can be obtained from the vehicle's relevant manufacturing information.

[0121] Furthermore, the window area when the vehicle window is open can be determined by multiplying the window opening ratio and the window area.

[0122] The vehicle has a corresponding control system, and the opening ratio of each window can be obtained from the relevant list of the window control unit in the control system. Similarly, the vehicle's speed can be obtained from the relevant list of the speed control unit in the vehicle control system.

[0123] When a vehicle opens its windows, the opening area of ​​each window can be obtained based on the opening ratio and the corresponding window area.

[0124] Alternatively, the window area of ​​each vehicle window can be obtained based on the following formula:

[0125] Front left window opening area = Total area of ​​front left window × Front left window opening ratio

[0126] Front right window opening area = Total front right window area × Front right window opening ratio

[0127] Rear left window opening area = Total area of ​​rear left window × Rear left window opening ratio

[0128] Rear right window opening area = Total area of ​​rear right windows × Rear right window opening ratio

[0129] Skylight opening area = Total skylight area × Skylight opening ratio

[0130] Furthermore, by adding up the opening areas of each window, the total flow area of ​​airflow into the vehicle when the windows are open can be obtained.

[0131] Total flow area = Front left window opening area + Front right window opening area + Rear left window opening area + Rear right window opening area + Sunroof opening area

[0132] S402, based on the window opening area and driving speed, obtains the airflow rate from outside the vehicle into the vehicle when the window is opened.

[0133] In this embodiment of the application, when the vehicle window is opened, the airflow from outside the vehicle into the vehicle has a set airflow rate, wherein the airflow rate is related to the vehicle's driving speed and the opening area of ​​the vehicle window to a certain extent.

[0134] For example, for two vehicles with the same window area but different driving speeds, under the same window opening time, the vehicle with the faster driving speed has a greater airflow into the vehicle than the vehicle with the slower driving speed.

[0135] In practice, when a vehicle window is opened, the air inside the vehicle may flow out of the vehicle. Therefore, the airflow rate of outside air into the vehicle when the window is open can be obtained based on the amount of air flowing from outside to inside the vehicle and the amount of air flowing from inside the vehicle to outside.

[0136] Furthermore, the product of driving speed and window area can be used as the first airflow from outside the vehicle to inside when the window is opened.

[0137] The first airflow rate can be obtained by the following formula: First airflow rate = Airflow rate flowing into the car from the windows + Airflow rate flowing into the car from the sunroof.

[0138] The airflow into the vehicle through the windows can be obtained by the following formula: Airflow into the vehicle through the windows = Driving speed × (Front left window opening area + Front right window opening area + Rear left window opening area + Right window opening area).

[0139] Due to factors such as the location and design of sunroofs on vehicles, the airflow rate from outside the vehicle through the sunroof differs from that through the windows, even with the same window area. A corresponding conversion factor can be assigned to the sunroof. The airflow rate from the sunroof can then be calculated using the following formula: Airflow rate from sunroof = Vehicle speed × Sunroof window area × Conversion factor.

[0140] The conversion factor can be adjusted based on changes in vehicle speed.

[0141] Correspondingly, the amount of air flowing from inside the vehicle to outside is related to the amount of air flowing from inside the vehicle to outside caused by the operation of the air vents of the temperature control system, as well as the amount of air flowing from inside the vehicle to outside caused by the movement of the vehicle through the downwind window when multiple windows are open.

[0142] Furthermore, the static airflow of the temperature control system and the downwind airflow when the vehicle windows are opened are obtained, and the sum of the static airflow and the downwind airflow is used as the second airflow from inside the vehicle to the outside when the vehicle windows are opened.

[0143] In practice, the temperature system has a static airflow rate, which can be determined based on the set level and set opening degree of the vehicle's temperature control system.

[0144] For example, if the temperature control system is set as a vehicle air conditioner, then the set level is the fan level of the vehicle air conditioner, and the set opening degree is the internal and external circulation opening degree of the vehicle air conditioner. Based on this parameter information, the relevant attribute list of the vehicle air conditioner can be queried, and then the fan air volume of the vehicle air conditioner under these two parameter settings can be obtained and determined as the static airflow of the temperature control system.

[0145] Correspondingly, when a vehicle window is open, there is a leeward opening. For example, for a vehicle with two windows on one side, when both windows on that side are open, the front window is the upwind opening for air to flow from outside to inside the vehicle, and the rear window is the leeward opening for air to flow from inside to outside the vehicle. The amount of air flowing from inside to outside the vehicle through the leeward opening is called the leeward airflow.

[0146] The downwind airflow when the vehicle windows are open can be determined by multiplying the vehicle's speed, the cross-sectional area of ​​the air inlet of the temperature control system, and the set opening ratio of the temperature control system.

[0147] Optionally, the formula for calculating the downwind airflow is as follows: Downwind airflow = driving speed × cross-sectional area of ​​the air inlet of the temperature control system × set opening ratio of the temperature control system.

[0148] Furthermore, based on the sum of the static airflow and the downwind airflow, the second airflow from inside the vehicle to outside when the vehicle window is opened can be determined.

[0149] The second airflow rate can be obtained by the following formula: Second airflow rate = Static airflow rate corresponding to the air outlet of the temperature control system + Downflow airflow rate corresponding to the downflow outlet.

[0150] Furthermore, the difference between the first airflow rate and the second airflow rate is taken as the airflow rate from outside the vehicle into the vehicle when the window is opened.

[0151] Optionally, the airflow from outside the vehicle into the vehicle when the windows are open can be obtained using the following formula: Airflow from outside the vehicle into the vehicle = Amount of air flowing from outside the vehicle into the vehicle - Amount of air flowing from inside the vehicle out of the vehicle.

[0152] S403 determines the corresponding airflow velocity based on the airflow rate and uses the airflow rate and airflow velocity as airflow parameters when the vehicle windows are opened.

[0153] In this embodiment of the application, the airflow velocity from outside the vehicle to inside the vehicle can be obtained based on the airflow rate of air flowing into the vehicle from outside when the vehicle window is opened and the corresponding window opening area.

[0154] Optionally, the airflow velocity from outside the vehicle to inside the vehicle when the window is opened can be determined based on the quotient of airflow rate and window area.

[0155] The airflow velocity can be calculated using the following formula: Airflow velocity = Airflow rate from outside the vehicle into the vehicle / Window area.

[0156] Furthermore, the acquired airflow rate and airflow velocity are used as airflow parameters for the flow of air from outside the vehicle into the vehicle when the windows are opened, and stored in a designated location. This storage at the designated location allows it to be accessed by subsequent calculations.

[0157] The method for predicting in-vehicle temperature when windows are open, proposed in this application, obtains the airflow rate of air flowing into the vehicle from outside based on the vehicle's speed and the window opening area, and then obtains the airflow velocity of the air flowing into the vehicle from outside based on the airflow rate. Furthermore, the obtained airflow rate and airflow velocity are determined as corresponding airflow parameters. In this application, the airflow parameters are obtained based on the driving speed and window opening area, improving the accuracy of the obtained airflow parameters and thus providing data support for subsequent calculations of relevant parameters related to changes in in-vehicle temperature.

[0158] Furthermore, after obtaining the predicted interior temperature when the vehicle windows are open, the interior temperature can be adjusted based on this predicted temperature. Figure 5 understand, Figure 5 This is a schematic flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, according to an embodiment of this application. Figure 5 As shown, the method includes:

[0159] S501, obtains the predicted interior temperature of the vehicle when the windows are open.

[0160] In this embodiment, the predicted interior temperature of the vehicle when the windows are open can be achieved through the above... Figures 1 to 5 The method provided in the illustrated embodiment will not be described in detail here.

[0161] S502 adjusts the vehicle's temperature control system based on the predicted interior temperature.

[0162] In practice, the vehicle's temperature control system has a set target temperature, which can be obtained by reading the configuration parameters in the temperature setting unit of the temperature control system.

[0163] In some implementations, the target temperature can be set by the vehicle's driver and / or passengers. In other implementations, the target temperature can be automatically set by the vehicle's temperature control system based on the relevant environmental conditions during vehicle use.

[0164] Furthermore, based on the predicted temperature inside the vehicle and the target temperature, the target output temperature of the temperature control system is obtained.

[0165] In this embodiment of the application, in order to keep the temperature inside the vehicle within the set range corresponding to the target temperature when the vehicle windows are open, the temperature control system can be adjusted.

[0166] The temperature control system can adjust the airflow temperature at its vents based on the predicted and target temperatures inside the vehicle, thereby regulating the temperature inside the vehicle.

[0167] For example, in scenarios where the predicted temperature inside the vehicle is lower than the target temperature, the airflow temperature at the air vents can be increased to raise the temperature inside the vehicle, thereby achieving temperature control.

[0168] For example, in scenarios where the predicted temperature inside the vehicle is higher than the target temperature, the airflow temperature at the air outlet can be reduced to lower the temperature inside the vehicle, thereby achieving temperature control.

[0169] The vehicle interior temperature control method proposed in this application adjusts the temperature control system based on the predicted interior temperature after the window is opened and the target temperature of the vehicle's temperature control system, thereby achieving temperature control of the vehicle interior. By using a short-cycle setting for the predicted interior temperature calculation unit, the calculation speed of the predicted interior temperature is improved, thus optimizing the response speed of the vehicle interior temperature system to temperature adjustments and improving the accuracy of interior temperature control.

[0170] To better understand the above embodiments, it can be combined with Figure 6 , Figure 6 This is a flowchart illustrating a method for controlling the interior temperature of a vehicle when the window is open, according to another embodiment of this application. Figure 6 As shown, where:

[0171] The heat transfer coefficient inside the vehicle is obtained by analyzing the airflow parameters from outside to inside when the windows are opened. Based on the heat transfer coefficient and the heat transfer area inside the vehicle, the heat transfer efficiency inside the vehicle when the windows are open is obtained, thus determining the rate of temperature change inside the vehicle when the windows are open. Furthermore, the predicted temperature inside the vehicle when the windows are open is determined based on the rate of temperature change. Finally, the vehicle's temperature control system is adjusted based on the predicted temperature and the target temperature inside the vehicle to control the temperature inside the vehicle when the windows are open. In this application, the temperature inside the vehicle is regulated when the windows are open, avoiding temperature fluctuations, optimizing the performance of the vehicle's temperature control system, improving the efficiency of temperature regulation, and enhancing the comfort of the occupants.
