Fig. 1 shows a schematic flow chart of a temperature control method according to an embodiment of the present application. Referring to fig. 1, the temperature control method includes steps S101 to S103.
Step S101, acquiring the current cold spot temperature and the current hot spot temperature; the current cold spot temperature is the temperature of a temperature sensitive part on the passenger body, and the current hot spot temperature is the temperature of a temperature stable part on the passenger body.
Specifically, the temperature-stabilized portion of the occupant is insensitive to temperature, and when the ambient temperature changes, the temperature change of the temperature-stabilized portion of the occupant is relatively small. The temperature-sensitive portion of the occupant is relatively sensitive to temperature, and when the ambient temperature changes, the temperature change of the temperature-sensitive portion of the occupant is relatively large. When a person wears the garment, hair, wearing habits (such as hat wearing and scarf wearing) and behavior habits (such as pocket inserting) are considered, and the main exposed skin part of the person is the face. The nose and the ears on the face of the human body are positioned at the peripheral part of the human body, the nose and the ears are sensitive to temperature, the temperature of the nose and the ears in different environments is greatly changed, for example, the nose and the ears of a person are frozen and stiff due to the excessively low temperature in cold, and the nose and the ears of the person are uncomfortable due to the temperature rise in hot, so that the temperature of the nose part of the passenger can be acquired, and the acquired temperature is taken as the current cold point temperature. The forehead and the inner side of the cheek of the face of the human body are insensitive to temperature, and when the ambient temperature changes, the temperature change of the part with stable temperature on the passenger body is smaller, so that the temperature of the forehead and the inner side of the cheek of the passenger can be collected, and the collected temperature is taken as the current hot spot temperature.
A temperature acquisition device (e.g., an infrared imaging camera) may be provided on the vehicle, through which the current cold spot temperature and the current hot spot temperature are obtained. The temperature acquisition device can acquire the temperature of the ears and the nose of the passenger respectively, and then calculate the average value of the temperature of the ears and the temperature of the nose to obtain the current cold point temperature. The current hot spot temperature is the temperature of the forehead and the inner side of the cheek of the passenger, the temperature acquisition device can acquire the temperature of the forehead and the temperature of the inner side of the cheek of the passenger respectively, and then the average value of the temperature of the forehead and the temperature of the inner side of the cheek is obtained to obtain the current hot spot temperature.
Step S102, the cold-warm state of the passenger is determined according to the current cold-spot temperature and the current hot-spot temperature.
Specifically, after the current cold spot temperature and the current hot spot temperature are obtained, the current cold spot temperature is subtracted from the current hot spot temperature, so that the current temperature difference can be obtained. And then determining the cold and warm states of the passengers according to the current hot spot temperature, the current temperature difference, the preset hot spot temperature and the preset temperature difference.
The temperature inside the forehead and cheek is relatively stable under different circumstances and higher than the temperature of other parts of the face. The nose and the ears are positioned at the peripheral parts of the human body, and the temperature of the nose and the ears is greatly changed under different environments, for example, the nose and the ears of a person are frozen and stiff due to the excessively low temperature in cold, and the nose and the ears of the person can be increased in temperature to generate discomfort in hot. Thus, when the human body feels hot, the temperature rise of the nose and ears is greater, and the temperature rise of the forehead and the inside of the cheek is smaller, and the difference between the current hot spot temperature and the current cold spot temperature is reduced, i.e., the current temperature difference is reduced. When the human body feels cold, the temperature drop of the nose and ears is larger, and the temperature drop of the forehead and the inner sides of the cheeks is smaller, and the difference between the current hot spot temperature and the current cold spot temperature increases, i.e. the current temperature difference increases. Therefore, compared with the existing method for detecting the cooling and heating state of the passenger, in the embodiment of the application, the current hot spot temperature is compared with the preset hot spot temperature, the current temperature difference is compared with the preset temperature difference, the cooling and heating state of the passenger can be more accurately determined according to the comparison result, and the accuracy of the cooling and heating state of the passenger is improved.
In some embodiments, the skin of a person is vasodilated to dissipate heat and the skin temperature is increased when hot; skin vasoconstriction reduces heat dissipation and skin temperature decreases in cold. However, when sweat is generated from the skin of a human body, the skin temperature monitored by the infrared imaging camera is lowered, and thus the temperature of the skin of the human body cannot be used as a standard for evaluating the cold and warm state of an occupant. In the method, the current hot spot temperature is compared with the preset hot spot temperature, the current temperature difference is compared with the preset temperature difference, and finally the cooling and heating state of the passenger can be accurately determined according to the two comparison results, so that the accuracy of the cooling and heating state of the passenger is improved.
For example, the current hot spot temperature is greater than the preset hot spot temperature, and the temperature of the forehead and the inside of the cheek of the occupant is greater than the preset hot spot temperature, indicating that the human body may be in a hot environment. If the current hot spot temperature is higher than the preset hot spot temperature and the current temperature difference is lower than the preset temperature difference, the cooling and heating state of the passenger can be determined to be a hot state.
The current hot spot temperature is less than the preset hot spot temperature, and the temperature of the forehead and the inner side of the cheek of the passenger is less than the preset hot spot temperature, which indicates that the human body may be in a cold environment. If the current hot spot temperature is smaller than the preset hot spot temperature and the current temperature difference is larger than the preset temperature difference, the cold and warm state of the passenger can be determined to be a cold state.
When a human body sweats due to heat, the temperature of the skin monitored by the infrared imaging camera is reduced, so that the situation that the current hot spot temperature is smaller than the preset hot spot temperature in a hot environment possibly occurs, but the current temperature difference is smaller than the preset temperature difference in the hot environment. Therefore, if the current hot spot temperature is smaller than the preset hot spot temperature and the current temperature difference is smaller than the preset temperature difference, the cooling and heating state of the passenger can be determined to be a hot state.
It should be noted that, the specific value of the preset hot spot temperature and the preset temperature difference may be set by a designer or a user according to actual requirements, or may be automatically generated according to identity information of the occupant and the current ambient temperature.
Because skin temperatures of different people are different in different environments due to gender, age, constitution and the like, identity information of passengers and environmental temperatures need to be referred to when determining preset hot spot temperatures and preset temperature differences. The designer can use the model training method to obtain the corresponding preset hot spot temperature and preset cold spot temperature of different passengers and different environmental temperatures. For example, a gaussian mixture model (Gaussian Mixture Model, GMM) may be used to determine the corresponding preset hot spot temperature and preset cold spot temperature for occupants of different identity information at different ambient temperatures. The GMM model belongs to an unsupervised machine learning algorithm, the input data does not need known results or marked information, and the internal relation and rule between the data are mined through learning of unmarked training samples.
The preset hot spot temperature is the temperature of the forehead and the inside of the cheeks of the occupant in a thermally comfortable state at a certain ambient temperature. The preset cold point temperature is the temperature of the ear and nose parts of the passenger in a thermal comfort state under a certain environmental temperature. The identity information, the ambient temperature, the preset hot spot temperature and the preset cold spot temperature of the passenger are in one-to-one correspondence, namely when the identity information and the ambient temperature are determined, the corresponding preset hot spot temperature and the corresponding preset cold spot temperature can be determined.
When detecting the temperature of an occupant on a vehicle and determining the cold and warm state of the occupant, firstly acquiring the identity information of the occupant and the current ambient temperature. And then determining a preset cold point temperature and a preset hot point temperature according to the identity information of the passengers and the ambient temperature. And then calculating the difference between the preset hot spot temperature and the preset cold spot temperature to obtain a preset temperature difference. Thus, the preset hot spot temperature and the preset temperature difference corresponding to the passengers are obtained.
And step S103, when the cooling and heating state of the passenger is determined to be a cold state or a hot state, controlling a temperature adjusting device on the vehicle to adjust the temperature of the area where the passenger is located.
Specifically, when the cold and warm states of the passengers are determined to be cold states or hot states, the temperature adjusting device on the vehicle is controlled to adjust the temperature of the area where the passengers are located, the temperature of the area where the passengers are located is adjusted to be proper temperature, automatic temperature adjustment is achieved, manual operation of the passengers is not needed, the intellectualization of temperature adjustment is improved, and therefore the experience of users is improved. In addition, when the cold and warm states of the passengers are determined to be cold states or hot states, the temperature adjusting device on the vehicle is controlled to adjust the temperature of the area where the passengers are located only, but not adjust other areas, so that other people are prevented from being influenced, and meanwhile, the energy-saving effect can be achieved.
When the cooling and heating state of the passenger is determined to be a cold state, for example, the temperature adjusting device is controlled to heat the area where the passenger is located, for example, an air outlet of an air conditioning system on a vehicle is controlled to blow warm air to the area where the passenger is located, or a heater on a seat where the passenger is located is controlled to heat the area where the passenger is located, so that the temperature of the area where the passenger is located is increased, and the comfort of the passenger is improved. When the cooling and heating state of the passenger is determined to be a hot state, the temperature adjusting device is controlled to cool the area where the passenger is located, for example, an air outlet of an air conditioning system on a vehicle is controlled to blow cold air to the area where the passenger is located, so that the temperature of the area where the passenger is located is reduced, and the comfort of the passenger is improved.
In some embodiments, the temperature regulating device comprises at least a first temperature regulating device and a second temperature regulating device, the first temperature regulating device is arranged on the seat, and the second temperature regulating device is arranged outside the seat. Step S103 may include step S1031 and step S1032.
In step S1031, when it is determined that the cooling and heating state of the occupant is a cold state or a hot state, the first temperature adjusting device is controlled to adjust the temperature of the region where the occupant is located.
Specifically, when the cold and warm states of the passenger are determined to be cold states or hot states, the first temperature adjusting device is controlled to adjust the temperature of the area where the passenger is located, namely, the temperature adjusting device on the seat where the passenger is located is controlled to adjust the temperature of the area where the passenger is located. When the temperature adjusting device on the seat adjusts the temperature of the area where the passenger is located, the temperature feeling of the passenger on other seats can not be affected, and the accuracy of temperature adjustment is improved.
The first temperature adjusting means may include a heater, a ventilator, a refrigerator, etc. provided on the seat, for example. When it is determined that the cooling and heating state of the occupant is a cold state, a heater or a ventilation device on the seat may be controlled to heat the occupant's location. When the cooling and heating state of the passenger is determined to be a hot state, a refrigerator or a ventilation device on the seat can be controlled to refrigerate the position of the passenger.
In step S1032, when the duration of the operation of the first temperature adjusting device reaches the preset time and the cold/hot state of the passenger is still cold or hot, the second temperature adjusting device is controlled to adjust the temperature of the area where the passenger is located.
In particular, the second thermostat may include a vent of an air conditioning system on the vehicle. When the working duration of the first temperature adjusting device reaches the preset time, the cold and warm states of the passengers are still cold or hot states, and the first temperature adjusting device cannot meet the temperature adjusting requirement of the passengers, at the moment, the second temperature adjusting device is controlled to adjust the temperature of the area where the passengers are located, namely, the first temperature adjusting device located on the seat and the second temperature adjusting device located outside the seat are controlled to adjust the temperature of the position where the passengers are located at the same time, so that the current requirement of the passengers on temperature adjustment is met, and the experience of the passengers is improved.
In some embodiments, the temperature regulating device comprises at least a first temperature regulating device and a second temperature regulating device, the first temperature regulating device is arranged on the seat, and the second temperature regulating device is arranged outside the seat.
Step S103 may further include: and calculating the absolute value of the difference between the current cold point temperature and the preset cold point temperature. And if the absolute value of the difference between the current cold point temperature and the preset cold point temperature is smaller than the preset difference, and the cold and warm state of the passenger is determined to be a cold state or a hot state, controlling the first temperature adjustment to adjust the temperature of the area where the passenger is located. And if the absolute value of the difference value between the current cold point temperature and the preset cold point temperature is larger than the preset difference value, and the cold and warm states of the passengers are determined to be cold states or hot states, controlling the first temperature adjusting device and the second temperature adjusting device to adjust the temperature of the area where the passengers are located.
Specifically, since the current cold spot temperature is the current temperature of the ears and the nose parts of the human body, the temperature change of the nose and the ears under different environments is large, namely, the current cold spot temperature is large. The preset cold point temperature is the temperature of ears and nose parts of the passengers at comfortable temperature, and the preset cold point temperature is a fixed value set by a designer.
When the cold and warm states of the passengers are in a cold state or a hot state, and the absolute value of the difference value between the current cold point temperature and the preset cold point temperature is smaller than the preset difference value, the passengers feel cold or hot at the moment, but the degree of the heat or cold is lighter, namely the temperature of the current environment is not too high or too low, at the moment, the first temperature adjusting device is controlled to adjust the temperature of the area where the passengers are located, namely the temperature adjusting device on the seat where the passengers are located is controlled to adjust the temperature of the area where the passengers are located. When the temperature adjusting device on the seat adjusts the temperature of the area where the passenger is located, the temperature feeling of the passenger on other seats can not be affected, and the accuracy of temperature adjustment is improved.
When the cold and warm state of the passenger is in a cold state or a hot state and the absolute value of the difference between the current cold point temperature and the preset cold point temperature is larger than the preset difference, the passenger feels cold or hot at the moment, the degree of the heat or cold is heavy, namely, the temperature of the current environment is too high or too low, and if the first temperature adjusting device is independently controlled to adjust the temperature of the area where the passenger is located, the requirement of the passenger on temperature adjustment can not be met. At the moment, the first temperature adjusting device and the second temperature adjusting device are controlled to adjust the temperature of the area where the passenger is located, namely, the first temperature adjusting device located on the seat and the second temperature adjusting device located outside the seat are controlled to adjust the temperature of the position where the passenger is located at the same time, so that the current demand of the passenger on temperature adjustment is met, and the experience of the passenger is improved.
It should be noted that, the designer may set the specific value of the preset difference according to the actual requirement, and the specific value of the preset difference is not limited herein.
Occupants in a vehicle include both the driver and the occupant (all but the driver) who is required to hold the steering wheel to effect steering of the vehicle. The driver may sweat during driving, and the reasons for the sweat include that the temperature of the hand is too high or too low, the sweat caused by the too high temperature is hot sweat, and the sweat caused by the too low temperature is cold sweat. When the driver's hand sweats, the driver is required to manually operate the temperature adjusting device to adjust the temperature of the steering wheel or the steering wheel region, for example, when cold sweat occurs, the driver is required to manually turn on the steering wheel heating device; when hot sweat is generated, a driver needs to manually adjust the air outlet of the air conditioner to blow to the steering wheel. Because the driver is driving the vehicle, the driver can not go to control temperature adjusting device immediately when the hand sweat carries out temperature regulation to the steering wheel to cause the uncomfortable hand of driver, the phenomenon that skidding probably appears when the driver controls the steering wheel simultaneously, has the potential safety hazard. If the driver manually operates the temperature adjusting device, the driver may be distracted, and potential safety hazards exist.
Based on the above-mentioned problems, as shown in fig. 2, the temperature control method provided in the embodiment of the present application further includes step S201 and step S202.
Step S201, a current resistance value of the palm of the driver is obtained.
Specifically, when the skin of a human body is dry, the resistance value of the skin is in the range of 40 kiloohms to 100 kiloohms; when the skin of a human body sweats, the resistance of the skin becomes small and drops to about 1000 ohms. When driving the vehicle, the driver needs to hold the steering wheel, and the palm and the steering wheel keep in contact. The skin on the surface of the palm also belongs to the skin of a human body, when the palm is dry, the resistance value of the palm is larger and is in the range of 40 kiloohms to 100 kiloohms; when the palm sweats and is wet, the resistance value of the palm becomes small and drops to about 1000 ohms. Therefore, whether the palm sweats or not can be judged by monitoring the resistance value of the palm of the driver. The embedded surface resistance sensor can be arranged on the steering wheel, and the resistance of the palm of the driver can be obtained through the surface resistance sensor.
Step S202, if the current resistance value is smaller than the preset resistance value, controlling the temperature adjusting device to adjust the temperature of the steering wheel according to the cold and warm state of the driver.
Specifically, the specific value of the preset resistance value can be set by a designer or a user according to actual requirements, and can also be automatically generated according to the identity information of the passenger and the current environmental temperature. The resistance value of the palm may be different for different drivers at different temperatures. Therefore, it is necessary to refer to the identity information of the driver and the ambient temperature when determining the preset resistance value. The designer can use the model training method to obtain the corresponding preset resistance values of different drivers and different environmental temperatures. For example, a gaussian mixture model (Gaussian Mixture Model, GMM) may be used to determine the corresponding preset resistance values for drivers of different identity information at different ambient temperatures. The GMM model belongs to an unsupervised machine learning algorithm, the input data does not need known results or marked information, and the internal relation and rule between the data are mined through learning of unmarked training samples. After the identity information of the driver and the current ambient temperature are determined, a corresponding preset resistance value may be determined.
And after the current resistance value and the preset resistance value are determined, comparing the current resistance value with the preset resistance value, and if the current resistance value is smaller than the preset resistance value, indicating that the palm of the driver sweats. And then controlling the temperature regulating device to regulate the temperature of the steering wheel according to the cold and warm states of the driver.
If the current resistance value is smaller than the preset resistance value, when the cold and warm state of the driver is the cold state, the palm of the driver is indicated to sweat, and at the moment, the temperature adjusting device is controlled to heat the steering wheel, for example, a heater on the steering wheel is controlled to heat the steering wheel, or an air outlet in an air conditioning system on the vehicle is controlled to blow warm air to the steering wheel, so that the temperature of the steering wheel is increased, and sweat caused by cold palm of the driver is avoided.
If the current resistance value is smaller than the preset resistance value, the driver indicates that the palm sweat is hot sweat when the cold and warm state of the driver is hot, and at the moment, the temperature adjusting device is controlled to cool the steering wheel, for example, an air outlet in an air conditioning system on a vehicle is controlled to blow cold air to the steering wheel, so that the temperature of the steering wheel is reduced, and the sweat of the palm of the driver caused by the heat is avoided.
Therefore, whether the palm of the driver sweats or not can be detected through the step S201 and the step S202, and when the palm of the driver appears, the temperature adjusting device is controlled to adjust the temperature of the steering wheel, so that the palm of the driver stops sweats, the driver does not need to manually operate, and the comfort of the driver and the driving safety are improved.
In one embodiment of the present application, the temperature control method further includes: when the cold and warm states of all passengers on the vehicle are in a cold state or a hot state, the temperature adjusting device is controlled to adjust the temperature of the whole vehicle.
Specifically, when the cold and warm states of all the passengers on the vehicle are cold, the temperature adjusting device is controlled to heat the whole vehicle, for example, all air outlets in the air conditioning system are controlled to blow warm air, or the heater on the seat with the passengers is controlled to heat, so that the temperature of the whole vehicle is increased, all the passengers are not cold any more, the temperature adjusting efficiency is improved, and the comfort of the passengers is improved.
When the cold and warm states of all passengers on the vehicle are hot, the temperature regulating device is controlled to refrigerate the whole vehicle, for example, all air outlets in the air conditioning system are controlled to blow cold air, so that the temperature of the whole vehicle is reduced, all passengers do not feel hot any more, the temperature regulating efficiency is improved, and the comfort of the passengers is improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
