[0035] Figure 1 1 is a flow chart of a vehicle air conditioning control method according to an embodiment of the present invention, the method is applied to a vehicle, the vehicle includes a plurality of seating areas, and each seating area is provided with an air conditioning partition. Figure 1 As shown, the vehicle air conditioning control method includes the following steps:

[0036] Step S101 , in response to a vehicle air conditioner start instruction, obtaining user types of multiple seating areas and environmental data of each seating area in the multiple seating areas.

[0037] The user type includes at least one of the following: different genders of humans, and different age stages of humans.

[0038] Exemplarily, the user type may include male and female, and the user type may also include infant stage, adolescent stage, middle-aged stage and elderly stage, wherein the infant stage corresponds to people aged 0 to 8, the adolescent stage corresponds to people aged 9 to 17, the middle-aged stage corresponds to people aged 18 to 45, and the elderly stage corresponds to people aged over 45. The user type may be determined by the driver interacting with the user interface of the vehicle terminal, or by a mobile terminal in communication with the vehicle terminal.

[0039] Exemplarily, the user type may also include a combination of different genders and different age stages, such as boys, girls, adult men and adult women, wherein boys refer to males aged 0 to 8, girls refer to females aged 0 to 8, adult men refer to males aged 18 to 45, and adult women refer to females aged 18 to 45.

[0040] The vehicle air conditioning start command can be issued by the driver after interacting with the user interface of the vehicle terminal, and can also be issued by a mobile terminal that is communicatively connected to the vehicle terminal.

[0041] Specifically, the vehicle acquires and updates the environmental data of each of the multiple seating areas in real time. The environmental data of each seating area includes the regional temperature, regional humidity, regional wind speed, and regional light intensity of the seating area. The environmental data of each seating area can be acquired in real time by sensors provided on the vehicle.

[0042] Step S102, determining thermal performance parameters of human clothing.

[0043] Among them, thermal performance parameters are used to characterize the thermal insulation ability of human clothing.

[0044] Specifically, in some embodiments of the present invention, the environmental data further includes vehicle exterior environmental data, and determining the thermal performance parameters of human clothing may optionally include one of the following steps:

[0045] Step S1021, determining thermal performance parameters of human clothing according to the in-vehicle environment data or the out-vehicle environment data.

[0046] Exemplarily, if the thermal performance parameters of human clothing are determined based on the in-car environment data, the in-car temperature when the driver just enters the car is obtained, and the in-car temperature is included in the in-car environment data. Then, based on the pre-established in-car temperature and the thermal performance parameters of human clothing, the thermal performance parameters of human clothing corresponding to the current in-car temperature are determined. It should be noted that there is an objective correlation between the in-car environment and human clothing; the types of clothing worn by people in different in-car environment data can be counted, and then the corresponding relationship between different in-car environment data and thermal performance parameters of human clothing can be established, and stored in the relevant electronic equipment of the vehicle or cloud server.

[0047] Exemplarily, if the thermal performance parameters of human clothing are determined based on the vehicle exterior environment data, the vehicle exterior temperature is obtained, and the vehicle exterior temperature is included in the vehicle exterior environment data. Then, based on the pre-established vehicle exterior temperature and the thermal performance parameters of human clothing, the thermal performance parameters of human clothing corresponding to the current vehicle exterior temperature are determined. It should be noted that there is an objective correlation between the vehicle exterior environment and human clothing; the types of clothing worn by people in different vehicle exterior environment data can be counted, and then the corresponding relationship between different vehicle exterior environment data and thermal performance parameters of human clothing can be established, and stored in the relevant electronic equipment of the vehicle or cloud server.

[0048] Step S1022, determining the thermal performance parameter according to the difference between the temperature of the human head and the surface temperature of the human clothing.

[0049] Among them, the temperature of the human head and the surface temperature of human clothing can be obtained through sensors.

[0050] For example, the sensor may be an infrared sensor, which senses the temperature of the human head and the temperature of the surface of the chest garment, respectively. The thermal performance parameter, i.e., the thermal insulation capacity of the garment, is then determined based on the difference between the temperature of the human head and the temperature of the surface of the chest garment acquired by the infrared sensor.

[0051] Step S1023, performing image recognition on the image of the human clothing to obtain thermal performance parameters.

[0052] For example, when the driver enters the vehicle, the image acquisition component acquires the driver's clothing image, and the type of clothing can be identified through the image recognition algorithm, and then the thermal performance parameters of the clothing are determined according to the type of clothing. The corresponding relationship between the clothing type and the thermal performance parameters is preset in the vehicle. The neural network model can also be pre-trained, and the human clothing image is input into the trained neural network model to obtain the thermal performance parameters.

[0053] It should be noted that when determining the thermal performance parameters of human clothing, the thermal performance parameters of user clothing in one seating area can be determined as the thermal performance parameters of user clothing in all seating areas, and the thermal performance parameters of user clothing in each seating area can also be determined separately.

[0054] Step S103, for each seating area, the current comfort level of the user in the seating area is determined in real time according to the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, the preset thermodynamic model and the thermal performance parameters.

[0055] Among them, the riding area 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.

[0056] Specifically, the preset thermodynamic model can output the current comfort level of the user in each seating area according to the environmental data and thermal performance parameters of each seating area. In some embodiments of the present invention, the comfort level is defined as nine values ​​from negative four to positive four, wherein when the comfort level is zero, it indicates the best comfort level, that is, the human body feels the most comfortable at this time, the comfort level from one to four indicates that the human body feels increasingly hot, and the comfort level from negative one to negative four indicates that the human body feels increasingly cold.

[0057] Step S104, for each seating area, according to the current comfort level of the user in the seating area, controlling the output of the air conditioning zone corresponding to the seating area.

[0058] Specifically, each user in each seating area has his or her own current comfort and target comfort. According to the current comfort of the user in the seating area, the output of the air conditioning zone corresponding to the seating area is controlled to make the current comfort of the user in the seating area become the target comfort. The target comfort values ​​corresponding to different types of users are set to zero, but the target comfort corresponding to different types of people has different temperatures. For example, when the target comfort of a boy is zero, the corresponding temperature is 27 degrees Celsius. When the target comfort of a girl is zero, the corresponding temperature is 28 degrees Celsius.

[0059] In the embodiment of the present invention, by controlling the output of the zoned air conditioner corresponding to each seating area based on the type of user in each seating area, different types of users can achieve the best comfort, thereby solving the technical problem that people of different ages and genders have different requirements for the cold and hot comfort in the car, which causes the driver to manually adjust the car air conditioner repeatedly. The current comfort of the human body is determined in real time, and the car air conditioner is automatically controlled to change the current comfort of the human body to the target comfort, so that the driver or passengers can feel comfortable throughout the journey. At the same time, compared with the existing automatic air conditioner that controls the air conditioner according to the temperature of the human head, in the embodiment of the present method, the current comfort of each user is determined by a preset thermodynamic model according to the in-car environmental parameters and thermal performance parameters. For each air-conditioning zone, the air-conditioning zone is controlled according to the current comfort of the user determined in real time to change the current comfort of the human body to the target comfort, so that the driver and all passengers can feel comfortable.

[0060] Optionally, the user type also includes animals, and the multiple seating areas include a driving area; the vehicle air-conditioning control method also includes: judging the user type corresponding to each seating area, if the user type is an animal, determining the output of the second air-conditioning zone based on the output of the first air-conditioning zone, wherein the first air-conditioning zone is the air-conditioning zone corresponding to the driving area, and the second air-conditioning zone is the air-conditioning zone corresponding to the seating area where the user type is an animal.

[0061] Specifically, when a user other than the cockpit is an animal, the output of the second air-conditioning zone corresponding to the seating area can be controlled to be the same as the output of the first air-conditioning zone corresponding to the driver's seating area, i.e. the cockpit. When the driver gets on the vehicle or drives, he only needs to adjust the air-conditioning zone of the driving area according to the type of animal to make both the animal and the person more comfortable. There is no need to adjust the air-conditioning zone where the animal is located separately, which simplifies the driver's operation and improves driving safety.

[0062] Furthermore, when a user other than the cockpit is an animal, the output of the first air conditioning zone can be multiplied by a preset animal coefficient to obtain a result as the output of the second air conditioning zone to make the animal more comfortable. For example, when the animal is a cat or a dog, the temperature requirement is higher than that of a human, so the output of the first air conditioning zone needs to be multiplied by a preset animal coefficient greater than one. The preset animal coefficient is preset in the vehicle, and different animals have different preset animal coefficients.

[0063] Optionally, the user type also includes cargo; the vehicle air-conditioning control method also includes: judging the user type corresponding to each seating area; if the user type is cargo, closing the third air-conditioning zone, the third air-conditioning zone is the air-conditioning zone corresponding to the seating area where the user type is cargo.

[0064] Specifically, the cargo specifically refers to cargo that does not need to be kept at a constant temperature, and the seating area where the user is cargo does not need to control the temperature. When the user of a non-cockpit is cargo, the third air-conditioning partition corresponding to the seating area is controlled to be closed.

[0065] Optionally, when there is no user in the seating area, the air-conditioning partition corresponding to the seating area is controlled to be closed.

[0066] Optionally, the preset thermodynamic model includes a thermodynamic physiological model and a thermodynamic psychological model. In step S103, for each seating area, determining the current comfort of the user in the seating area in real time according to the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, the preset thermodynamic model and the thermal performance parameters may include the following steps:

[0067] Step S1031 , for each seating area, a thermodynamic physiological state of a human body is determined using a thermodynamic physiological model based on the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, and the thermal performance parameters.

[0068] Among them, the thermal physiological state is used to characterize the human body's physiological response to hot and cold conditions.

[0069] 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. The thermodynamic physiological model uses different preset parameters to determine the thermophysiological state of different user types. That is, under the same riding area environmental data, the thermophysiological state of different user types will also be different.

[0070] Step S1032, for each seating area, a thermodynamic psychological state of a human body is determined using a thermodynamic psychological model based on the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, and the thermophysiological state of the user in the seating area.

[0071] Among them, thermal psychological state is used to characterize the human body's psychological feelings about hot and cold conditions.

[0072] Specifically, the thermal psychological state includes nine states: very cold, cold, cool, slightly cool, comfortable, warm, hot, very hot and very hot. The above nine thermal psychological states correspond to the nine values ​​of comfort. When determining the thermal psychological state of the human body, the thermodynamic psychological model determines the human skin temperature and epithalamus temperature based on the in-vehicle environmental data, and then determines the thermal psychological state of the human body based on the change in epithalamus temperature, the change in skin temperature and the thermal physiological state.

[0073] Step S1033: for each seating area, determine the current comfort level of the users in the seating area according to the thermal psychological state of the users in the seating area.

[0074] Specifically, the current comfort level of each seating area user is determined according to the corresponding relationship between the thermal psychological state and the comfort level value.

[0075] In this embodiment, the current comfort level of each user in the seating area 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 human comfort level based on the head temperature.

[0076] Optionally, in step S1031, for each seating area, determining the thermal physiological state of the human body using a thermodynamic physiological model based on the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, and the thermal performance parameters may include the following steps:

[0077] Step S1031a, for each seating area, the human body's epidermal temperature and hypothalamus temperature are determined using a thermodynamic physiological model according to the user type corresponding to the seating area, the seating area environment data corresponding to the seating area, and the thermal performance parameters.

[0078] Specifically, a temperature calculation formula is determined according to the user type corresponding to each seating area, wherein different user types correspond to different temperature calculation formulas. After the temperature calculation formula is determined, the thermodynamic physiological model determines the epidermal temperature and hypothalamic temperature according to the seating area environmental data, thermal performance parameters and temperature calculation formula corresponding to each seating area.

[0079] It should be noted that the difference in the above-mentioned temperature calculation formula refers to the different values ​​corresponding to some preset parameters related to human functions in the temperature calculation formula. For example, the human metabolic parameters of people of different ages or genders are different. Among them, the temperature calculation formula determines the human epidermal 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 temperature formula is used to calculate the human epidermal temperature or the epithalamus temperature is determined by the value of a discriminant parameter in the formula. The discriminant parameter has two values, one is used when calculating the human epidermal temperature, and the other is used when calculating the epithalamus temperature.
