[0033] Example 1

[0034] Figure 1 is a flow chart of an air conditioning adjustment method provided in Example 1 of the present application. This embodiment of the present application is applicable to vehicle air conditioning adjustment. The method can be performed by an air conditioning adjustment device, which can be implemented in hardware and / or software and can be deployed in a vehicle.

[0035] Referring to FIG1 , the air conditioning adjustment method includes:

[0036] S101. Obtain the sealing status of the vehicle at the current moment.

[0037] The term "sealed state" can be understood as a state in which the interior of the vehicle is sealed, i.e., a state in which there is no air exchange between the vehicle and the outside world. The vehicle's sealed state can be determined by detecting whether the vehicle's sealed components are in a sealed state. Sealed components may include at least one of the following: vehicle windows, sunroofs, and doors. If any of the vehicle's sealed components are open, the vehicle interior is not in a sealed state.

[0038] In some embodiments, the vehicle's sealing state may be determined to be open when any one of the vehicle's windows is detected to be open. For another example, the vehicle's sealing state may be determined to be closed when all of the vehicle's windows are closed. For another example, the vehicle's sealing state may be determined to be closed when all of the vehicle's windows and doors are closed.

[0039] S102: Compare the sealing status at the current moment with the sealing status at the historical moment to obtain a sealing change detection result.

[0040] The historical moment is before the current moment. In practice, the vehicle's sealing status can be periodically checked. The period can be 3 minutes. The historical moment can refer to a moment in a period adjacent to the current moment. Periodically checking the vehicle's sealing status yields the vehicle's sealing status at the corresponding moment. The sealing change detection result indicates whether the vehicle's sealing status has changed within the recent short period, where the recent short period is the time between the historical moment and the current moment.

[0041] Exemplarily, if the sealing status at the current moment is the same as the sealing status at the historical moment, the sealing change detection result is determined to be no change; if the sealing status at the current moment is different from the sealing status at the historical moment, the sealing change detection result is determined to be a change.

[0042] As shown in Figure 2, Line 1 represents the expected temperature curve; Line 2 represents the real-time temperature curve inside the car; Line 3 represents the wind speed level curve inside the car; Line 4 represents the closed state of the car window, the triangle indicates that the intelligent air-conditioning temperature adjustment is currently being performed; the square indicates that the intelligent air-conditioning wind speed adjustment is currently being performed; when the value of Line 4 is 0, it indicates that the sealing state of the car window is open at the current moment, that is, the sealing state of the vehicle is open at the current moment; when the value of Line 4 is 1, it indicates that the sealing state of the car window is closed at the current moment, that is, the sealing state of the vehicle is closed; in Figure 2, the temperature inside the car has changed due to the change in the sealing state of the car window.

[0043] In some embodiments, the cycle is 3 minutes, the current time is 9:40, and the vehicle's sealing status detection result is: the vehicle's sealing status is open; the historical time is 9:37, and the vehicle's sealing status detection result is: the vehicle's sealing status is closed; after comparison, the sealing change detection result is that the vehicle's sealing status has changed, and the vehicle's sealing status has changed from closed to open.

[0044] S103 : In response to the seal change detection result being no change, obtaining the interior temperature of the vehicle.

[0045] Optionally, if the vehicle's seal status check results in no change and the vehicle's interior temperature is stable, the temperature sensor can be used to detect the vehicle's interior temperature to determine whether the vehicle's air conditioning needs to be adjusted. In practice, if the seal change detection result changes, the interior temperature will change within a short period of time. Adjusting the air conditioning at this time will not be effective and will increase the air conditioning power required, thereby increasing energy consumption.

[0046] In some embodiments, when the sealing change detection result is no change, the temperature inside the vehicle is obtained as 30 degrees through the vehicle's temperature sensor.

[0047] S104: Adjust operating parameters of the vehicle's air conditioner according to the temperature inside the vehicle, so that the air conditioner operates according to the adjusted operating parameters.

[0048] The operating parameters are used to control the operation of the air conditioner to adjust the temperature, humidity, and change rate in the vehicle. For example, the operating parameters may include the set temperature, set humidity, set operating mode, and set wind speed of the air conditioner.

[0049] Optionally, the vehicle air conditioning operation is controlled according to the operating parameters to adjust the temperature inside the vehicle so as to adjust the temperature inside the vehicle to the temperature required by the user.

[0050] In some embodiments, if the temperature sensor detects that the temperature inside the car is 36 degrees Celsius, the operating parameters of the air conditioner in the car can be adjusted. For example, by adjusting the air conditioner temperature to 24 degrees Celsius and other operating parameters, the temperature inside the car can be adjusted to lower the temperature inside the car.

[0051] In an embodiment of the present application, by obtaining the sealing status of the vehicle at the current moment, it is convenient to obtain the ventilation status of the current vehicle; the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result, and whether the sealing status of the vehicle has changed in a short time is obtained, so as to facilitate targeted air-conditioning adjustment operations in combination with different vehicle sealing states; when the sealing change detection result is no change, the vehicle's interior temperature is obtained; the operating parameters of the vehicle's air conditioner are adjusted according to the interior temperature, so that the air conditioner operates according to the adjusted operating parameters, and whether the operating parameters of the air conditioner need to be adjusted and the adjustment value are determined according to the interior temperature. The temperature control strategy of the air conditioner can be adjusted only when the interior temperature state is stable, the interior temperature adjustment can be accurately achieved, the energy consumption increased by frequently changing the temperature control strategy of the air conditioner can be reduced, and redundant energy consumption can be reduced.

[0052] Optionally, obtaining the sealing status of the vehicle at the current moment includes: at the current moment, detecting whether the windows and doors of the vehicle are in a closed state; in response to the windows and doors of the vehicle being in a closed state, determining that the sealing status of the vehicle at the current moment is closed.

[0053] The vehicle windows may include sunroofs and windows on doors, etc. When all the vehicle windows and doors are in a closed state at the current moment, the sealing state of the vehicle at the current moment is closed. When any one of the vehicle windows and doors is in an open state at the current moment, the sealing state of the vehicle at the current moment is open.

[0054] By detecting whether the doors and windows are in a closed state, it can be determined whether the vehicle's sealing state is closed, and the sealing state of the vehicle can be accurately detected.

[0055] Optionally, obtaining the sealing status of the vehicle at the current moment includes: when the vehicle's intelligent air conditioner is in the intelligent adjustment process, in response to the current intelligent adjustment being different from the first intelligent adjustment, obtaining the sealing status of the vehicle at the current moment.

[0056] A smart air conditioner can be understood as an air conditioner with automatic adjustment capabilities. Based on the in-vehicle and external environments, it acquires signals from temperature, humidity, and air quality sensors, analyzes and determines these signals, and then automatically selects at least one of the following functions: cooling, heating, dehumidification, and air purification. Current intelligent adjustment refers to the intelligent adjustment process of the smart air conditioner at the current moment. Initial intelligent adjustment refers to the first intelligent adjustment after the smart air conditioner is started.

[0057] In reality, the smart air conditioner can only adjust the in-car temperature based on the environment when it enters the intelligent adjustment process. If the smart air conditioner is not in the intelligent adjustment process, detecting the current vehicle sealing status cannot automatically adjust the temperature, and the corresponding detection operation is redundant.

[0058] It can be understood that the first intelligent adjustment process is to adjust the temperature inside the car at the current moment. Therefore, the first intelligent adjustment process is to adjust the demand caused by the short-term change in the sealing state of the vehicle. Accordingly, the smart air conditioner needs to be intelligently adjusted at the current moment.

[0059] In some embodiments, while a vehicle's smart air conditioner is in the process of intelligent adjustment, the current time is 9:40 a.m., the vehicle interior temperature is 36 degrees Celsius, and based on the vehicle interior temperature, the vehicle's air conditioner is adjusted to cooling with an air flow rate of 0 meters per second. The first time of intelligent adjustment is 8:00 a.m., the vehicle interior temperature is 10 degrees Celsius, and based on the vehicle interior temperature, the vehicle's air conditioner is adjusted to heating with an air flow rate of 0 meters per second. In response to the current intelligent adjustment being different from the first intelligent adjustment, the vehicle's sealing status at the current moment is obtained.

[0060] By obtaining the sealing status of the vehicle during the process of the smart air conditioner entering the smart adjustment process to realize automatic control adjustment of the air conditioner, redundant operations can be reduced, energy waste can be reduced, and when the vehicle's smart air conditioner is in the smart adjustment process and the current smart adjustment is different from the first smart adjustment, the sealing status of the vehicle at the current moment can be obtained. When the current smart adjustment process is not aimed at the adjustment needs caused by the short-term change of the vehicle's sealing status, the sealing status of the vehicle at the current moment can be obtained, thereby realizing accurate adjustment control of the smart air conditioner and improving control flexibility and precision.

[0061] Example 2

[0062] Figure 3 is a flow chart of an air conditioning adjustment method provided in Example 2 of the present application. Based on the above-mentioned embodiment, the present embodiment improves the air conditioning adjustment method.

[0063] In some embodiments, “comparing the sealing state at the current moment with the sealing state at the historical moment to obtain a sealing change detection result” is refined to “in response to the sealing state at the current moment being sealed, comparing the sealing state at the current moment with the sealing state at the historical moment to obtain a sealing change detection result.

[0064] For parts not described in detail in the embodiments of this application, please refer to the description of other embodiments.

[0065] Referring to FIG3 , the air conditioning adjustment method includes:

[0066] S301. Obtain the sealing status of the vehicle at the current moment.

[0067] S302: In response to the sealing state at the current moment being closed, the sealing state at the current moment is compared with the sealing state at the historical moment to obtain a sealing change detection result.

[0068] Optionally, the vehicle's sealing status is detected using a vehicle sensor. If the current sealing status is closed, the current sealing status is compared with the sealing status at a historical time. If the current sealing status is inconsistent with the sealing status at a historical time, vehicle sealing status change information is obtained, and the cause of the change in vehicle interior temperature is determined to be a change in the sealing status, and the air conditioning adjustment strategy does not need to be changed. If the current sealing status is consistent with the sealing status at a historical time, the air conditioning adjustment strategy needs to be changed to adjust the vehicle interior temperature.

[0069] As shown in Figure 4, Line 1 represents the expected temperature curve; Line 2 represents the real-time temperature curve inside the vehicle; Line 3 represents the wind speed level curve inside the vehicle; Line 4 represents the closed state of the window, the triangle represents that the intelligent air-conditioning temperature adjustment is currently being performed; the square represents that the intelligent air-conditioning wind speed adjustment is currently being performed; when the value of Line 4 is 0, it indicates that the sealing state of the window is open at the current moment, that is, the sealing state of the vehicle is open at the current moment; when the value of Line 4 is 1, it indicates that the sealing state of the window is closed at the current moment, that is, the sealing state of the vehicle is closed.

[0070] The top chart in Figure 4 is a schematic diagram of intelligent temperature adjustment in the related art, while the bottom chart is a schematic diagram of the intelligent temperature adjustment method of the present application. When intelligent adjustment is activated, the intelligent air conditioner begins its first intelligent adjustment strategy change. This change is a common operation in both the related art and the present application's intelligent adjustment process. Due to changes in the window sealing state, the interior temperature changes, and the vehicle also performs intelligent air conditioning adjustment, resulting in energy waste. Through an improved air conditioning adjustment strategy, the current vehicle sealing state is compared with the sealing state at a historical time. By analyzing the sealing change detection results, if it is determined that the change in interior temperature is due to a change in the vehicle's sealing state within a short period of time, the vehicle does not change the air conditioning adjustment strategy and does not perform intelligent air conditioning adjustment, thus saving vehicle energy. Therefore, based on the air conditioning adjustment method of the present application, there is no need to adjust the air conditioning parameters, and thus there is no need to change to a second intelligent adjustment strategy. Accordingly, in Figure 4, the top chart represents the intelligent adjustment process of the related art, with two sets of triangles and squares, while the bottom chart represents the intelligent adjustment process of the present application, with only one set of triangles and squares.

[0071] In some embodiments, the current time is 9:40, and the sealing status of the vehicle is detected by the vehicle sensor. At 9:40, the sealing status of the vehicle is closed, the preset time is 3 minutes, and the historical time is 9:37. If the sealing status of the vehicle is closed at 9:37, the sealing status at the current time is consistent with the sealing status at the historical time, and air conditioning is required to adjust the temperature in the car; if the sealing status of the vehicle is open at 9:37, the sealing status at the current time is inconsistent with the sealing status at the historical time, and air conditioning is not required to adjust the temperature in the car.

[0072] S303: In response to the seal change detection result being no change, obtaining the interior temperature of the vehicle.

[0073] S304: Adjust operating parameters of the vehicle's air conditioner according to the temperature inside the vehicle, so that the air conditioner operates according to the adjusted operating parameters.

[0074] The embodiment of the present application responds to the sealing state being closed at the current moment, compares the sealing state at the current moment with the sealing state at the historical moment, and obtains the sealing change detection result, which can facilitate the analysis of the cause of the temperature change in the vehicle, and determine whether the cause of the temperature change in the vehicle is due to a change in the sealing state of the vehicle. In addition, only when the sealing state remains unchanged, the operating parameters of the air conditioner are adjusted to reduce the air conditioner overload caused by the change in the vehicle temperature caused by the unsealed state, reduce the energy consumption of the air conditioner, and improve the accuracy of the air conditioner adjustment.

[0075] Optionally, in response to the sealing status at the current moment being closed, the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result, including: in response to the sealing status at the current moment being closed, the thermal comfort level of the vehicle at the current moment is compared with the thermal comfort level at the historical moment to obtain a thermal comfort change detection result; in response to the thermal comfort change detection result being changed, the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result.

[0076] The thermal comfort level can be understood as the temperature and humidity levels set to achieve optimal comfort within a certain temperature and humidity range. The thermal comfort level is divided into seven levels, with higher levels indicating a warmer sensation. The predicted mean vote (PMV) is the average of the group's votes on the seven thermal comfort levels (+3 to -3). The predicted mean vote is used as the thermal comfort level. The seven thermal comfort levels are as follows: hot (>=35°C), PMV +3; comfortable / relatively hot ([25,35°C), PMV +2; comfortable / relatively comfortable ([20,25°C), PMV +1; cool ([15,20°C), PMV 0; cool ([8,15°C), PMV -1); slightly cool / relatively cool ([0,8°C), PMV -2); and cold (<0°C), PMV -3. Factors affecting thermal sensation index include the following: M, W, I cl , t a , t r , Var, relative humidity and P a M is the user's metabolic rate, in watts per square meter (W / m 2 ), the higher the metabolic rate, the higher the PMV value; W is the effective mechanical power, that is, the mechanical work done by the human body, the unit is watt per square meter (W / m2); I cl The thermal resistance of clothing. The greater the thermal resistance, the better the thermal insulation performance. The unit is square meter Kelvin per watt (m 2 ·K / W); f cl is the clothing surface area coefficient; t a Air temperature, in degrees Celsius (℃); is the mean radiation temperature in degrees Celsius (℃); Var is the relative wind speed in meters per second (m / s); P a is the water vapor partial pressure, the pressure of water vapor in moist air, in Pa (P a ). t cl The surface temperature of the garment, in degrees Celsius (°C); 1 metabolic unit = 1 met = 58.2 W / m 2 ; 1 clothing unit = 1clo = 0.155m 2 ℃ / W. Water vapor pressure + dry air pressure = atmospheric pressure. Relative humidity: The ratio of the water vapor partial pressure of moist air at a given temperature to the saturated water vapor partial pressure at that temperature. The higher the water vapor partial pressure, the higher the moisture content. At normal temperatures, the water vapor partial pressure accounts for a very low percentage of atmospheric pressure. It is lower in cold regions than in humid and hot regions, and lower in winter than in summer, but the difference between day and night is not significant. Water vapor partial pressure decreases with increasing altitude, and the rate of decrease is greater than that of air pressure. The formula for calculating the PMV value is shown below.

[0077] Optionally, the sealing status of the vehicle at the current moment is obtained through a vehicle sensor. In response to the sealing status at the current moment being closed, the thermal comfort level of the vehicle at the current moment and the thermal comfort level at the historical moment are obtained through a temperature sensor. The thermal comfort level of the vehicle at the current moment is compared with the thermal comfort level at the historical moment to obtain a thermal comfort change detection result. If the thermal comfort change detection result is a change, the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result. If the thermal comfort change detection result is no change, there is no need to obtain the sealing status of the vehicle at the current moment and the sealing status at the historical moment.

[0078] In some embodiments, the current time is 9:40, and the sealing status of the vehicle at the current time is obtained as closed through the vehicle sensor, and the thermal comfort level of the vehicle at the current time is obtained as hot through the temperature sensor, the preset time is 3 minutes, and the historical time is 9:37. The thermal comfort level of the vehicle at the historical time is obtained as cold through the temperature sensor, and the thermal comfort level of the vehicle at the current time is compared with the thermal comfort level at the historical time, and the thermal comfort change detection result is change; then the sealing status of the vehicle at 9:40 is obtained as sealed and the sealing status at 9:37 is obtained as open, and the sealing status at the current time is compared with the sealing status at the historical time, and the sealing change detection result is change.

[0079] In response to the sealing state being closed at the current moment, the thermal comfort level of the vehicle at the current moment is compared with the thermal comfort level at the historical moment to obtain a thermal comfort change detection result. Based on the thermal comfort change detection result, it is determined whether the thermal comfort level has changed, so as to determine whether the temperature inside the vehicle has changed. When the thermal comfort change detection result is a change, the sealing state at the current moment is compared with the sealing state at the historical moment to obtain a sealing change detection result, so as to determine whether the temperature change inside the vehicle is caused by a change in the sealing state of the vehicle, thereby facilitating the execution of air-conditioning adjustment decisions and adjusting the air-conditioning control strategy when the thermal comfort level changes, thereby improving the accuracy of the temperature adjustment inside the vehicle.

[0080] Optionally, in response to the thermal comfort change detection result being a change, the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result, including: in response to the thermal comfort change detection result being a change, detecting the driving time of the vehicle; in response to the driving time being greater than or equal to a preset time threshold, comparing the sealing status at the current moment with the sealing status at the historical moment to obtain a sealing change detection result.

[0081] Driving time can be understood as the time period between the start of driving and the current time. The preset driving time threshold is used to determine whether the vehicle has been driving for a sufficient period of time. In practice, when a vehicle first starts driving, there will be a significant difference between the vehicle's temperature and the outside temperature. As the vehicle moves, the interior temperature fluctuates erratically. Therefore, it is necessary to wait for the interior temperature to stabilize before adjusting the air conditioning parameters.

[0082] Optionally, the thermal comfort level of the vehicle at the current moment and at the historical moment is obtained through a temperature sensor, and the thermal comfort levels at the current moment and at the historical moment are compared to obtain a thermal comfort change detection result. In response to the thermal comfort change detection result being a change, the driving time of the vehicle is detected. In response to the driving time being greater than or equal to a preset time threshold, the sealing status at the current moment and at the historical moment are obtained through the vehicle sensor, and the sealing status at the current moment and at the historical moment are compared to obtain a detection result of whether the sealing status has changed.

[0083] In some embodiments, the thermal comfort level of the vehicle at the current moment and the historical moment is obtained through a temperature sensor. The current moment is 9:40, and the thermal comfort level of the vehicle at the current moment is obtained through the temperature sensor as hot. The preset time is 3 minutes. The historical moment is 9:37. The thermal comfort level of the vehicle at the historical moment is obtained through the temperature sensor as cold. The thermal comfort levels at the current moment and the historical moment are compared to obtain a thermal comfort change detection result. The thermal comfort change detection result is change. The preset duration threshold is 10 minutes. The driving time of the detected vehicle is 11 minutes. The driving time is greater than the preset duration threshold. The sealing status at the current moment and the sealing status at the historical moment are obtained through the vehicle sensor. The current moment is 9:40, and the sealing status of the vehicle at the current moment is obtained through the vehicle sensor as closed. The historical moment is 9:37, and the sealing status of the vehicle at the current moment is obtained through the vehicle sensor as open. The sealing status at the current moment is compared with the sealing status at the historical moment, and it is found that the sealing status has changed.

[0084] By responding to the change in the thermal comfort detection result, the vehicle's driving time is detected. If the temperature inside the vehicle changes, the vehicle's driving time is detected to determine the length of the vehicle's driving time; if the driving time is greater than or equal to the preset time threshold, the sealing status at the current moment is compared with the sealing status at the historical moment to obtain a sealing change detection result, thereby determining whether the temperature change inside the vehicle is caused by a short-term change in the vehicle's sealing status, which facilitates the execution of air-conditioning adjustment decisions. After the vehicle has been driving for a period of time and the temperature inside the vehicle is stable, the air-conditioning adjustment can be performed. The air-conditioning control can be accurately adjusted when the air-conditioning control strategy does not match the user's required temperature, thereby improving the accuracy and stability of the air-conditioning adjustment.

[0085] Optionally, before comparing the sealing status at the current moment with the sealing status at the historical moment, it also includes: detecting the current vehicle temperature, wind speed and vehicle humidity; obtaining the user metabolic rate and clothing thermal resistance at the current moment; and calculating the thermal comfort level at the current moment based on the current vehicle temperature, wind speed, vehicle humidity, user metabolic rate and clothing thermal resistance.

[0086] The interior temperature can be understood as the average temperature inside the vehicle. Wind speed can be understood as the rate of air movement relative to a fixed point in the vehicle. Humidity can be understood as the degree of dryness or wetness of the interior air, specifically, the amount of water vapor contained in the air. At a given temperature, the less water vapor a given volume of interior air contains, the drier the interior air; the more water vapor, the more humid the interior air. The user's metabolic rate can be understood as the amount of heat generated per unit time by the user's body surface area. Clothing thermal resistance can be understood as a parameter reflecting the thermal insulation performance of clothing. Its value is inversely proportional to the clothing's thermal conductivity. Measured data is available for the thermal resistance of various clothing items. The user's metabolic rate and clothing thermal resistance can be obtained through user input or, with user authorization, by capturing an interior image of the user. After image processing of the user in the interior image, the user's body shape, gender, age, and clothing are determined. The user's metabolic rate is calculated based on the user's body shape, gender, and age, and their pre-set relationships. The clothing thermal resistance is calculated based on the user's gender, age, and clothing, and their pre-set relationships.

[0087] Optionally, before comparing the sealing status at the current moment with the sealing status at the historical moment, the vehicle sensor is used to obtain the current vehicle interior temperature, wind speed and humidity; the metabolic rate is between 46 and 232 W / m 2 The range of 0.8 to 4 met is suitable for PMV. According to GB / T 18048-2008 / ISO 8996:2004 Thermal environment human ergonomics - Determination of metabolic rate, the four determination methods are screening method, observation method, analytical method and measurement method. Among them (the measured person is male / 30 years old / 175cm / 170kg, female / 30 years old / 170cm / 60kg), screening method and observation method are feasible. Among them, observation method has higher accuracy, so observation method is selected as the metabolic rate determination method. Taking the driver as the standard, the metabolic rate of the human body in the car is determined to be 70W / m 2 (1.2met). The movement of people in the car is restricted, and the driver's movement is limited to his hands and feet.

According to the international standard "ISO_99202007_Ergonomics of thermal environment. Evaluation of thermal insulation and anti-evaporation of clothing", the overall I cl The calculation formula is as follows, where l cl is the thermal resistance of the clothing; m is the weight of the clothing (without shoes), in kilograms; A COV,0 It is the body surface area not covered by clothes as a percentage of the total body surface area; A COV,1It is the body surface area covered by a single layer of clothing as a percentage of the total body surface area. cl =0.919+0.255×m-0.00874×A COV,0 -0.00510×A COV,1

[0088] The corresponding clothing combinations and thermal resistance values ​​under different ambient temperatures are as follows: Hot (>=35℃): short sleeves + shorts + thin socks + sandals: 0.3clo; Thermal comfort / relatively hot ([25,35)℃): short sleeves + shorts + socks + single shoes: 0.5clo; Comfortable / relatively comfortable ([20,25)℃): long sleeves + trousers / dress + shoes and socks: 0.7clo; Cool ([15,20)℃): long sleeves + trousers + jacket + shoes and socks: 1.0clo; Cool ([8,15)℃): long-sleeved underwear + V-neck sweater + trousers + jacket + shoes and socks: 1.3clo; Slightly cold / relatively cold ([0,8)℃): long-sleeved underwear + round-neck sweater + trousers + thin down jacket + shoes and socks: 1.5clo; Cold (<0℃): long-sleeved underwear + turtleneck sweater + trousers + thick down jacket + shoes and socks: 2.0clo.

[0089] In some embodiments, before comparing the current sealing status with the historical sealing status, it is determined that the current vehicle interior temperature is 32 degrees Celsius, the wind speed is 0 meters per second, and the interior humidity is 80%. Furthermore, the driver's metabolic rate is 1.2 meters, and the clothing thermal resistance is 0.4 clo. The vehicle's thermal comfort level is determined to be hot.
