[0036] Figure 1 FIG. 1 is a flow chart of a vehicle air conditioning control method according to an embodiment of the present invention, which can be executed in a vehicle terminal. Figure 1 As shown, the vehicle air conditioning control method includes the following steps:

[0037] Step S101 : acquiring environmental data in real time in response to a first control instruction.

[0038] The environmental data includes in-vehicle environmental data, and the first control instruction is an instruction to activate automatic control of the vehicle air conditioner. The first control instruction can be issued by the driver through interaction with the user interface of the vehicle terminal, or by a mobile terminal that is communicatively connected to the vehicle terminal.

[0039] Specifically, environmental data is acquired and continuously updated by the vehicle in real time. This in-vehicle environmental data includes in-vehicle temperature, humidity, wind speed, and light intensity. This in-vehicle environmental data can be acquired using sensors installed inside and outside the vehicle.

[0040] Step S102: determining thermal performance parameters of the human clothing.

[0041] Among them, thermal performance parameters are used to characterize the thermal insulation ability of human clothing.

[0042] Specifically, in some embodiments of the present invention, the environmental data further includes external vehicle environmental data, and determining the thermal performance parameters of human clothing may optionally include one of the following steps:

[0043] Step S1021 : determining thermal performance parameters of human clothing based on in-vehicle environment data or out-vehicle environment data.

[0044] For example, if thermal performance parameters of clothing are determined based on in-vehicle environmental data, the in-vehicle temperature immediately after the driver enters the vehicle is obtained, which is included in the in-vehicle environmental data. Then, based on the pre-established in-vehicle temperature and thermal performance parameters of clothing, the thermal performance parameters of clothing corresponding to the current in-vehicle temperature are determined. It should be noted that there is an objective correlation between the in-vehicle environment and clothing. The types of clothing worn by people at different in-vehicle environmental data points can be statistically analyzed to establish a correspondence between different in-vehicle environmental data and thermal performance parameters of clothing, which can then be stored in the vehicle's relevant electronic devices or a cloud server.

[0045] For example, if thermal performance parameters of clothing are determined based on external vehicle environment data, the external vehicle temperature, which is included in the external vehicle environment data, is obtained. Then, based on the pre-established external vehicle temperature and thermal performance parameters of clothing, the thermal performance parameters of clothing corresponding to the current external vehicle temperature are determined. It should be noted that there is an objective correlation between the external vehicle environment and clothing. The type of clothing worn by a person in response to different external vehicle environment data can be statistically analyzed to establish a corresponding relationship between different external vehicle environment data and the thermal performance parameters of clothing, which can be stored in the vehicle's relevant electronic equipment or a cloud server.

[0046] Step S1022: determining thermal performance parameters according to the difference between the human head temperature and the surface temperature of the human clothing.

[0047] Among them, the temperature of the human head and the surface temperature of the human clothing can be obtained through sensors.

[0048] For example, the sensor may be an infrared sensor that senses the temperature of the human head and the temperature of the garment's chest. The thermal performance parameter, i.e., the garment's thermal insulation capability, is then determined based on the difference between the head and chest temperatures obtained by the infrared sensor.

[0049] Step S1023: performing image recognition on the image of the human clothing to obtain thermal performance parameters.

[0050] For example, an image acquisition component captures an image of the driver's clothing. An image recognition algorithm identifies the clothing type, and then determines the thermal performance parameters of the clothing based on the clothing type. The correspondence between clothing type and thermal performance parameters is pre-set in the vehicle. Alternatively, a pre-trained neural network model can be used to input the clothing image into the trained neural network model to obtain the thermal performance parameters.

[0051] Step S103 , determining the current comfort level in real time based on the in-vehicle environment data, thermal performance parameters, and a preset thermodynamic model.

[0052] Among them, the in-vehicle environmental data and thermal performance parameters are used as input parameters of the preset thermodynamic model to determine the current comfort level, and the current comfort level is used to characterize the current comfort level of the human body.

[0053] Specifically, the thermodynamic model can output the current comfort level of the human body based on in-vehicle environmental data and thermal performance parameters. In this solution, the comfort level is defined as seven values ​​ranging from -3 to +3. A comfort level of zero indicates optimal comfort and the most comfortable feeling. A comfort level of one to three indicates increasing heat sensation, and a comfort level of -1 to -3 indicates increasing coldness.

[0054] Step S104 : controlling the vehicle air conditioner according to the current comfort level so that the current comfort level becomes the target comfort level.

[0055] Specifically, after determining the current comfort level of the human body, if the current comfort level is less than zero, the output of the vehicle air conditioner is controlled to increase the temperature inside the vehicle, thereby bringing the current comfort level to the target comfort level, that is, the comfort level value becomes zero. If the current comfort level is greater than zero, the output of the vehicle air conditioner is controlled to cool the vehicle, thereby bringing the current comfort level to the target comfort level.

[0056] It should be noted that the vehicle air conditioner is automatically controlled based on the current comfort level by the device implementing the vehicle air conditioner control method provided by the present invention. In this method, the current comfort level is continuously acquired. Therefore, adjusting the vehicle air conditioner based on the current comfort level ensures that the current comfort level of the vehicle occupants is always at the target comfort level while using the air conditioner, maintaining optimal comfort for the human body.

[0057] In an embodiment of the present invention, first, in response to an instruction for automatic control of the vehicle air conditioner, environmental data is acquired in real time, including in-vehicle and out-vehicle environmental data; thermal performance parameters of human clothing are determined based on the out-vehicle environmental data; the current comfort level is determined in real time based on the in-vehicle environmental data, the thermal performance parameters, and a preset thermodynamic model, wherein the in-vehicle environmental data and the thermal performance parameters serve as input parameters of the preset thermodynamic model to determine the current comfort level, which is used to characterize the current comfort level of the human body; and the vehicle air conditioner is controlled based on the current comfort level to achieve a target comfort level. This method, by determining the current comfort level of the human body in real time and automatically controlling the vehicle air conditioner to achieve the target comfort level, can ensure comfort for the driver or passenger throughout the entire journey, thereby resolving the technical problem of drivers having to repeatedly adjust the air conditioner due to excessively high or low temperatures in the vehicle, which creates a driving safety hazard.

[0058] Optionally, in step S103, determining the current comfort level in real time based on the in-vehicle environment data, thermal performance parameters, and a preset thermodynamic model may include the following steps:

[0059] Step S1031 : determining the thermal physiological state of the human body using a thermodynamic physiological model based on the in-vehicle environment data and thermal performance parameters.

[0060] Among them, the thermal physiological state is used to characterize the human body's physiological response to hot and cold conditions.

[0061] Specifically, the thermophysiological state includes shivering, sweating, expansion, and contraction. The thermodynamic physiological model can calculate and determine the current thermophysiological state of the human body based on the in-vehicle environmental data and thermal performance parameters.

[0062] Step S1032 : determining the thermal psychological state of the human body using a thermodynamic psychological model based on the in-vehicle environment data and the thermal physiological state.

[0063] Among them, thermal psychological state is used to represent the human body's psychological feelings about hot and cold conditions.

[0064] Specifically, thermal states include cold, cool, slightly cool, comfortable, warm, hot, and very hot. These seven states correspond to seven comfort levels. The thermodynamic psychological model determines the thermal state of the human body by determining the skin temperature and epithalamus temperature based on in-vehicle environmental data. The model then determines the thermal state based on the change in epithalamus temperature, skin temperature, and the thermophysiological state.

[0065] Step S1033: determining the current comfort level according to the thermal psychological state of the human body.

[0066] Specifically, the current comfort level of the human body is determined according to the corresponding relationship between the thermal psychological state and the comfort level value.

[0067] In this embodiment, the comfort level of the human body is determined based on the thermal physiological state and the thermal psychological state, and the comfort level obtained is more accurate compared to the traditional method of directly judging the comfort level of the human body based on the head temperature.

[0068] Optionally, in step S1031, determining the human body's thermal physiological state using a thermodynamic physiological model based on the in-vehicle environment data and thermal performance parameters may include the following steps:

[0069] Step S1031a: determining the human body's skin temperature and epithalamus temperature using a thermodynamic psychological model based on the in-vehicle environment data and thermal performance parameters.

[0070] Specifically, the human skin temperature and epithalamus temperature are determined using a preset formula based on the in-vehicle environmental data and thermal performance parameters. The preset formula determines the human skin temperature and epithalamus temperature based on preset human tissue parameters, preset blood parameters, preset human metabolic parameters, in-vehicle environmental data, and thermal performance parameters. It should be noted that whether the preset formula is used to calculate the human skin temperature or the epithalamus temperature is determined by the value of a discriminant parameter in the preset formula. The discriminant parameter has two values: one for calculating the human skin temperature and the other for calculating the epithalamus temperature.

[0071] Step S1031b, determining the thermal physiological state of the human body according to the skin temperature and the epithalamus temperature.

[0072] Specifically, the thermal physiological state of the human body is determined according to the amount and rate of change of the epidermal temperature and the amount and rate of change of the epithalamus temperature.

[0073] Optionally, in step S104, controlling the vehicle air conditioner according to the current comfort level so as to change the current comfort level to the target comfort level may include the following steps:

[0074] Step S1041 : determining the adjustment parameters of the vehicle air conditioner according to the difference between the current comfort level value and the target comfort level value.

[0075] Specifically, the adjustment parameters include parameters required for calculating the outlet air temperature, temperature damper control parameters, mode damper control parameters, circulation damper control parameters, and blower voltage control parameters. The parameters required for calculating the outlet air temperature are used to calculate the air temperature of the vehicle air conditioner; the temperature damper control parameters are used to control the temperature damper of the vehicle air conditioner; the mode damper control parameters are used to control the mode damper of the vehicle air conditioner; the circulation damper control parameters are used to control the circulation damper of the vehicle air conditioner; and the blower voltage control parameters are used to control the blower voltage. These parameters are determined based on the difference between the current comfort level and the target comfort level.

[0076] Step S1042: Control the vehicle air conditioner according to the adjustment parameters.

[0077] Specifically, the output of the vehicle air conditioner is controlled according to parameters required for air outlet temperature calculation, temperature damper control parameters, mode damper control parameters, circulation damper control parameters, and blower voltage control parameters.

[0078] Optionally, the vehicle air-conditioning control method further includes: in response to a second control instruction, controlling the vehicle air-conditioning to change the current comfort level to a cold comfort level, wherein the value of the cold comfort level is lower than the value of the target comfort level.

[0079] Specifically, the second control instruction is a cold comfort control instruction, and the comfort value corresponding to cold comfort can be defined as minus 1. Controlling the vehicle air conditioner to change the current comfort level to cold comfort means controlling the output of the vehicle air conditioner to change the current comfort level to minus 1.

[0080] This embodiment can meet the needs of drivers who prefer a cooler car interior.

[0081] Optionally, the vehicle air-conditioning control method further includes: in response to a third control instruction, controlling the vehicle air-conditioning so that the current comfort level changes to a thermal comfort level, wherein the value of the thermal comfort level is higher than the value of the target comfort level.

[0082] Specifically, the third control instruction is a thermal comfort control instruction, and the comfort value corresponding to thermal comfort can be defined as 1. Controlling the vehicle air conditioner to change the current comfort level to thermal comfort means controlling the output of the vehicle air conditioner to change the current comfort level to 1.

[0083] It should be noted that the second control instruction and the third control instruction may be issued by the driver through interaction with the user interface of the vehicle-mounted terminal, or may be issued by a mobile terminal that is communicatively connected to the vehicle-mounted terminal.

[0084] This embodiment can meet the needs of drivers who like the car to be warmer.

[0085] Reference Figure 2 As shown, in some embodiments of the present invention, a vehicle air conditioning control method includes: first, starting the vehicle air conditioner. After starting the air conditioner, the current comfort level of a human body is calculated in real time. The real-time calculation of the current comfort level requires real-time acquisition of in-vehicle and exterior environmental data. Based on the real-time acquisition of the in-vehicle and parking space environmental data, the current comfort level is output in real time using a preset thermodynamic model. After obtaining the real-time current comfort level, a human body requirement, i.e., a human comfort demand, is determined. If the current mode is automatic, the device executing the vehicle air conditioning control method automatically controls the vehicle air conditioner in real time based on a target comfort level to achieve the target comfort level. If the current mode is cooling demand mode, the device executing the vehicle air conditioning control method automatically controls the vehicle air conditioner in real time based on the cooling comfort level to achieve the cooling comfort level. If the current mode is heating demand mode, the device executing the vehicle air conditioning control method automatically controls the vehicle air conditioner in real time based on the heating comfort level to achieve the heating comfort level.
