Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the embodiments of the present application.

In the related art, the vehicle-mounted air conditioner can realize the functions of refrigerating, heating, ventilating and the like in the vehicle cabin, so that a driver and a passenger can obtain more comfortable driving experience in the process of using the vehicle. However, the operation parameters of the vehicle-mounted air conditioner need to be manually adjusted, so that the vehicle-mounted air conditioner is inconvenient to use and poor in user experience.

Therefore, some technologies propose adopting an automatic adjustment mode, so that the automatic adjustment of the vehicle-mounted air conditioner can be realized according to the parameters of the environment, and the user experience is improved. However, this approach is still unsatisfactory, mainly because it mechanically determines the operating parameters of the vehicle air conditioner based on the environmental parameters, and ignores the user's own experience of the vehicle air conditioner.

In particular, occupants in a vehicle may have different physiological states, for example, the occupants may have just finished moving or have fallen asleep in the vehicle or have suffered a cold or fever, and the physiological parameters such as heart rate, metabolic rate, etc. may have a larger change than normal. In this case, the passenger needs to adjust the operation parameters of the vehicle-mounted air conditioner after entering the cabin to make the environment in the vehicle comfortable, including manually adjusting the proper temperature, wind speed gear, circulation mode, etc. As the physiological state of the occupant changes, for example, gradually calms down or wakes up after exercise, the operation parameters of the vehicle-mounted air conditioner may need to be frequently adjusted, which is inconvenient to use. In addition, for the driver, it is necessary to disperse energy to adjust the air conditioner during driving, and there is a driving safety hazard to some extent.

On the basis of the above situation, as shown in fig. 1, a vehicle-mounted air conditioner control method in an embodiment of the present application includes:

01: acquiring physiological state parameters and environmental parameters of an occupant;

02: and controlling the vehicle-mounted air conditioner to operate according to the adjusted operating parameters according to the physiological state parameters and the environment parameters so as to enable the thermal environment in the vehicle to be matched with the physiological state of the passenger.

The embodiment of the application also provides an electronic device, which comprises a memory and a processor, wherein the memory stores a computer program, and the processor is used for acquiring the physiological state parameters and the environmental parameters of the passengers and controlling the vehicle-mounted air conditioner to operate according to the adjusted operating parameters according to the physiological state parameters and the environmental parameters so as to match the thermal environment in the vehicle with the physiological state of the passengers. The electronic device of the embodiment of the application may be a server of the vehicle or a controller mounted on the vehicle.

The application also provides an air conditioning system, which comprises the electronic device of the embodiment of the application.

The application also provides a vehicle comprising a vehicle body and the electronic device or the air conditioning system in the embodiment of the application.

Specifically, in the embodiment of the application, firstly, the physiological state parameters and the environmental parameters of the passengers in the running process of the vehicle are required to be obtained. The occupant physiological state parameter may graphically describe the physiological state of an occupant in a traveling vehicle. The environmental parameters can then describe the characteristics of the vehicle itself in motion and the environment in which it is located. The process of acquiring the physiological state parameters of the passengers can be realized through vehicle-mounted detection instruments such as vehicle-mounted cameras, for example, the vehicle-mounted cameras can recognize the shot images, and then the comfort level of the passengers in the vehicle can be judged through the expression exhibited by the passengers. Similarly, environmental parameters capable of representing various characteristics of the vehicle itself and the environment in which the vehicle is traveling can be obtained by the vehicle-mounted detecting instrument, for example, the vehicle-mounted temperature sensor can sense the temperature in the vehicle, and the obtained sensing result needs to participate in the calculation of the comfort level of the passengers in the vehicle.

Further, according to the comfort level of the passenger in the vehicle under the current vehicle related parameters, the vehicle-mounted air conditioner is controlled to operate according to the adjusted operation parameters, so that the adjusted vehicle interior environment is matched with the physiological state of the passenger, and the vehicle-mounted air conditioner is controlled to operate according to the adjusted operation parameters, so that the comfort required by the passenger is met.

It is particularly noted that the vehicle-mounted air conditioner parameters are timely adjusted along with the changes of the physiological state parameters and the environmental parameters of the passengers, so that the electric energy waste caused by unsuitable operation parameters can be avoided to a certain extent.

In particular, the physiological state parameters of the occupant may include at least one of heart rate, metabolic rate, skin temperature, and garment thermal resistance. Heart rate is the number of heart beats per minute of a person, is one of the basis for judging whether the occupant is in a motion or a static state, and can also be used as consideration of physiological states of the occupant, for example, when the person is excited, heated or severely coughs, the heart rate is higher than that when the person is calm. The metabolic rate can represent the heat generated by the surface area of the human body in unit time, and the working states of the circulatory system and the respiratory system of the passengers in unit time are represented. Skin temperature generally refers to the average temperature of human skin and can reflect the body temperature of an occupant. The thermal resistance of the garment is a parameter reflecting the warmth retention degree of the garment. The physiological parameters of the passengers can be obtained through vehicle-mounted detection equipment such as vehicle-mounted infrared sensors, vehicle-mounted cameras and the like. It will be appreciated that any of heart rate, metabolic rate, skin temperature, and garment thermal resistance may affect occupant comfort when the vehicle air conditioner is operated under the same parameters.

In addition, various sensors in the vehicle can also collect other physiological states of passengers. For example, a pressure sensor may be installed in a cabin of a vehicle to identify whether passengers are present in the vehicle, and the like.

Specifically, the environmental parameter may include at least one of an in-vehicle temperature, an in-vehicle humidity, an in-vehicle wind speed, and an in-vehicle solar parameter value. The in-vehicle temperature may be acquired by an in-vehicle temperature sensor. The in-vehicle humidity may be acquired by an in-vehicle humidity sensor. The wind speed in the vehicle generally refers to the wind speed in the running of the vehicle-mounted air conditioner, and can be obtained by acquiring the running parameters of the vehicle-mounted air conditioner. The value of the sun parameter in the vehicle can be obtained by an on-board sun sensor, which comprises a photosensitive semiconductor and can reflect the sun illumination intensity.

The environmental parameters in the vehicle can be obtained through corresponding vehicle-mounted detection equipment with sensors. It will be appreciated that any one of the in-vehicle temperature, in-vehicle humidity, in-vehicle wind speed, and in-vehicle solar parameter values may affect the comfort of the occupant when the vehicle air conditioner is operated under the same parameters.

In addition, various sensors in the vehicle can also collect other environmental conditions in the vehicle. For example, an air quality detection device may be installed in the vehicle as a means for determining whether ventilation is required in the vehicle.

In some embodiments, referring to fig. 2, step 02 includes:

021: calculating a current thermal comfort value according to the physiological state parameter and the environmental parameter;

022: when the current thermal comfort value deviates from the preset thermal comfort value range, the vehicle-mounted air conditioner is controlled to operate according to the adjusted operation parameters, so that the thermal environment is matched with the physiological state of the passenger.

In some embodiments, the processor is configured to calculate a current thermal comfort value according to the physiological state parameter and the environmental parameter, and when the current thermal comfort value deviates from a preset thermal comfort value range, control the vehicle-mounted air conditioner to operate according to the adjusted operation parameter, so that the thermal environment matches the physiological state of the occupant.

Specifically, after various sensors in the vehicle-mounted system acquire physiological state parameters and environmental parameters of the passenger, the current thermal comfort value can be calculated according to the values of the parameters. Wherein the thermal comfort value may represent occupant satisfaction with the thermal environment.

In some examples, the thermal comfort value may be calculated using a PTS (PREDICTED THERMAL Sensation) model, and the resulting thermal comfort index PTS may be obtained by the relationship "pts=f (HR, M, T _skin、I_cl, tin, Φ, va, W)". Where HR represents heart rate, M represents metabolic rate, T _skin represents skin temperature, I _cl represents garment thermal resistance, tin represents in-vehicle temperature, phi represents in-vehicle humidity, va represents in-vehicle wind speed, and W represents in-vehicle solar parameter values. The calculation process of the thermal comfort index shows that the satisfaction degree of passengers on the internal thermal environment of the vehicle is related to physiological state parameters and environmental parameters of a plurality of passengers.

After the current thermal comfort value is calculated, the current thermal comfort value may be compared with a preset thermal comfort value. The method for obtaining the preset thermal comfort value may be preset when the vehicle leaves the factory, or may be self-set by the passenger, or downloaded from the cloud storage in a networking manner, and the specific obtaining method is not limited herein.

Different values of the thermal comfort index correspond to different satisfaction degrees of passengers on the thermal environment. Under the preset thermal comfort value, the satisfaction degree of passengers on the internal thermal environment of the vehicle is higher. If the current thermal comfort value is different from the preset thermal comfort value, the current in-vehicle thermal environment is indicated to cause certain uncomfortable feeling to the passengers, and at the moment, the operation parameters of the vehicle-mounted air conditioner are required to be adjusted so that the environment temperature is matched with the physiological state parameters of the passengers.

In some embodiments, referring to fig. 3, step 021 includes:

0211: an occupant input of various physiological state parameter weights that participate in the calculation of the current thermal comfort value is received.

In some embodiments, the processor is configured to receive an occupant input of various physiological state parameter weights that are involved in the calculation of the current thermal comfort value.

Specifically, when calculating the current thermal comfort value from the acquired physiological state parameters and environmental parameters of the occupants, the weight of the physiological state parameters of each occupant may also be determined according to the preferences of different occupants. For example, after the passenger 1 finishes moving into the vehicle, it is customary to adjust the vehicle-mounted air conditioner to a higher wind speed and a lower temperature; due to the difference in physique, the passenger 2 does not adjust the operation parameters of the vehicle-mounted air conditioner after finishing the movement into the vehicle. In the actual calculation process, the passenger 1 can input the weights of physiological state parameters related to movement such as heart rate, metabolic rate and the like into larger values, and the influence of the corresponding passenger physiological state parameters on the adjustment of the vehicle-mounted air conditioner operation parameter setting is increased; similarly, the passenger 2 can input the weights of physiological state parameters related to movement such as heart rate and metabolic rate as smaller values, and the weights of the corresponding physiological state parameters of the passenger in calculating the current comfort index value are reduced, so that the air conditioner operation parameters are not greatly changed due to whether the passenger 2 moves or not.

In addition, when calculating the current thermal comfort value based on the acquired physiological state parameters and environmental parameters of the occupant, the weight of each environmental parameter may also be determined based on the preferences of different occupants. For example, if the passenger is sensitive to humidity, the weight of the humidity parameter in the vehicle can be input into a larger value, the weight of the current comfort index value of the humidity parameter in the vehicle is increased, and the air conditioner operation parameter is controlled to be changed more sensitively when the humidity parameter in the vehicle changes.

In some embodiments, the predetermined thermal comfort value range is a predetermined thermal comfort value range corresponding to a current somatosensory level.

Specifically, the current thermal comfort value calculated by the physiological state parameter and the environment parameter can intuitively represent the satisfaction degree of the passenger on the current thermal environment by using the positive and negative values and the absolute values of the values. However, in the case of an application scene change, the same current thermal comfort value may represent a different degree of satisfaction of the occupant with the current thermal environment. For example, for the same operating temperature of a vehicle-mounted air conditioner, there may be some difference in satisfaction among teenagers and the long people, or men and women. At this time, the current thermal environment visual feeling of the occupant at this time needs to be represented by the current somatosensory level corresponding to the current thermal comfort value.

In one example, when the current thermal comfort value is positive, it may be representative that the occupant actually experiences the current thermal environment as being hotter, whereas when the current thermal comfort value is negative, it may be representative that the occupant actually experiences the current thermal environment as being colder. Further, the absolute value of the thermal comfort index may represent the magnitude of the degree to which the occupant actually experiences warmth or coldness.

In some embodiments, the predetermined thermal comfort value range corresponding to the somatosensory level is derived from an empirical table comprising a correspondence of thermal comfort values to occupant somatosensory levels.

Specifically, in the foregoing embodiments, the current thermal comfort value calculated by the physiological state parameter and the environmental parameter of the occupant may not represent the actual satisfaction of different occupants with the current thermal environment, and thus the operation parameter of the air conditioner may not match the physiological state parameter of the occupant. At this time, an empirical table of thermal comfort values may be introduced to determine the satisfaction of the current occupant with the thermal environment. Wherein, the experience table comprises the correspondence between the thermal comfort value range and different somatosensory grades of passengers. In one example, table 1 below is a possible empirical table in which a range of thermal comfort values and their corresponding meanings are expressed.

TABLE 1

In one example, the thermal comfort value is-2.5, and the somatosensory grade is cool as shown by looking up table 1, which indicates that the occupant is currently feeling cool in the vehicle.

The thermal comfort values and corresponding somatosensory ratings in table 1 can be obtained by using the PTS model. Compared with the constant corresponding relation between the traditional environment parameters and the thermal sensation of the human, the PTS model can reflect the adaptability difference of different people to the thermal environment. For example, if the thermal comfort value of an occupant varies more during the same temperature difference, the member's ability to adapt to the thermal environment is poorer. The corresponding relation between the thermal comfort value and the corresponding somatosensory grade in the empirical table established according to the PTS model can be flexibly changed according to different climatic regions, different seasons, or the gender, age and the like of the passengers. For example, the calculated thermal comfort value is maximum for occupants in cold areas throughout the year at about 20 ℃, whereas the calculated thermal comfort value may be maximum for most occupants in warm in winter and cool in summer at about 25 ℃. The PTS model is used for carrying out multiple fitting on the thermal comfort value and the comfort body feeling level of different passenger grades, and finally an experience table database suitable for different types of passengers can be formed.

Further, in order to determine whether the operation parameters of the vehicle-mounted air conditioner need to be adjusted, conditions for meeting the thermal comfort index need to be set. The condition for maintaining the operation parameters of the vehicle-mounted air conditioner may be that the thermal comfort value corresponds to a level of comfort. The vehicle-mounted air conditioner can be controlled to maintain the operation parameters when the thermal comfort value falls within a first preset range, for example, the first preset range of the thermal comfort value can be set as a thermal comfort value epsilon-1, 1 according to the table 1, and the passenger feel comfortable when the corresponding somatosensory grade is within the thermal comfort value epsilon-1, 1.

In some embodiments, referring to fig. 4, the range of preset thermal comfort values corresponding to the somatosensory level is obtained from an empirical table, and step 022 includes:

0221: and when the current thermal comfort value falls into a first preset range, controlling the vehicle-mounted air conditioner to maintain the current operation parameters.

In some embodiments, the processor is configured to control the vehicle-mounted air conditioner to maintain the current operation parameters when the current thermal comfort value falls within a first preset range.

Specifically, in order to determine whether adjustment of the vehicle-mounted air conditioner operation parameters is required, conditions that the thermal comfort index satisfies are set. The condition for maintaining the operation parameters of the vehicle-mounted air conditioner may be that the thermal comfort value corresponds to a level of comfort. The vehicle-mounted air conditioner can be controlled to maintain the operation parameters when the thermal comfort value falls within a first preset range, for example, the first preset range of the thermal comfort value can be set as a thermal comfort value epsilon-1, 1 according to the table 1, and the passenger feel comfortable when the corresponding somatosensory grade is within the thermal comfort value epsilon-1, 1. When the thermal comfort value falls into the first preset range, the passenger has no obvious uncomfortable feeling on the current in-vehicle thermal environment, and the passenger can be regarded as the in-vehicle environment to be matched with the physiological state parameters of the passenger under the current air-conditioning operation parameters, namely, the operation parameters of the current in-vehicle air-conditioner do not need to be changed. Therefore, the vehicle-mounted air conditioner can be controlled to maintain the current operation parameters.

In some embodiments, referring to fig. 5, the predetermined thermal comfort value range corresponding to the somatosensory level is obtained from an empirical table, and step 022 further includes:

0222: and after receiving the input of the passenger representing the energy saving will and when the current thermal comfort value falls into a second preset range, controlling the vehicle-mounted air conditioner to maintain the current operation parameters.

In some embodiments, the processor is configured to control the vehicle-mounted air conditioner to maintain the current operation parameters when the current thermal comfort value falls within the second preset range after receiving the input indicating the desire of energy saving by the occupant.

Specifically, in the foregoing step of the control method, each time the thermal comfort index value does not fall within the first preset range and the air conditioner operation parameter is controlled to be adjusted, the step of comparing the recalculated current thermal comfort value with the empirical table of thermal comfort values introduced in the foregoing embodiment is required to be returned, so that the adjustment process of the air conditioner operation parameter can keep up with the change of the physiological state parameter of the occupant as much as possible.

It can be appreciated that if the value of the first preset range is too severe, the frequent and unnecessary adjustment of the operation parameters of the air conditioner may be caused under the condition that the occupant has little adverse effect on the environment in the vehicle, thereby wasting electric energy. At this time, the occupant may input an energy saving wish, such as "turn on energy saving mode", to the in-vehicle air conditioner.

In order to reduce frequent adjustment of the air conditioner operation parameters after the occupant inputs the energy saving wish to the vehicle-mounted air conditioner, a second preset range within which the thermal comfort index value needs to fall may be set. The second preset range is larger than the first preset range. For example, in the case where the first preset range is "thermal comfort value e [ -1,1]", the second preset range may be set to "thermal comfort value e [ -2,2]". Compared with the adjusting process of controlling the air conditioner operation parameters according to the first preset range, when the thermal comfort value is-2 or 2, the air conditioner operation parameters still do not need to be adjusted although the thermal comfort value is out of the first preset range and fall into the second preset range, and the vehicle-mounted air conditioner is controlled to maintain the current operation parameters.

In some embodiments, referring to fig. 6, the vehicle includes a plurality of seating areas, each seating area is provided with an air conditioning zone, and step 021 further includes:

0212: for each seating area, a corresponding current thermal comfort value is calculated from the physiological state parameter and the environmental parameter corresponding to the seating area.

Step 022 further includes:

0223: when the current thermal comfort value of the riding area deviates from the preset thermal comfort value range, controlling the air conditioner subareas corresponding to the riding area to operate according to the adjusted operation parameters, so that the thermal environment of the riding area is matched with the physiological state of the passengers.

In some embodiments, the processor is configured to calculate, for each of the seating areas, a corresponding current thermal comfort value according to a physiological state parameter and an environmental parameter corresponding to the seating area, and when the current thermal comfort value of the seating area deviates from a preset thermal comfort value range, control an air-conditioning partition corresponding to the seating area to operate according to the adjusted operation parameter, so that the thermal environment of the seating area matches with the physiological state of the occupant.

Specifically, in order to further meet the requirement of saving electric energy, various operation parameters corresponding to each air outlet in the vehicle of the vehicle-mounted air conditioner can be controlled to be adjusted. The vehicle seat cabin can comprise a plurality of riding areas, and each riding area is correspondingly provided with an air conditioning partition. As shown in fig. 7, in one example, the riding area of the car may be divided into main driving, sub driving, left rear, middle, right rear and other riding areas, and each riding area may be provided with a corresponding air conditioning zone.

Further, the current thermal comfort value calculated by the physiological state parameter and the environmental parameter of the occupant in each seating area may be different from the preset thermal comfort value, and the satisfaction degree of the occupant in each seating area on the thermal environment is determined according to the empirical table in which the preset thermal comfort index value is introduced. The specific comparison method is recorded in more detail in the foregoing steps, and is not described herein.

In the control interface of the vehicle-mounted air conditioner, the occupant can view the physiological state parameter and the environmental parameter in each seating area. As shown in fig. 8, a possible control interface situation of the vehicle-mounted air conditioner is shown, wherein after a button of a riding area is selected and pressed, a selection frame of each physiological state parameter of a main driver can be popped up, a button for increasing the metabolic rate is hollow, which indicates that the current metabolic rate has reached the maximum value to which the vehicle-mounted air conditioner can respond, the vehicle-mounted air conditioner cannot be adjusted upwards, and the rest numerical value size adjusting keys can be adjusted. The left side of the interface indicates that the current main driving temperature is 23 ℃, the relative humidity is 65%, and the date of the day is "2023, 1 month, 1 day, sunday".

The partition control of the vehicle-mounted air conditioner can avoid that the vehicle-mounted air conditioner operation parameters are adjusted according to the extreme requirements of passengers in a certain riding area, and electric energy is wasted under the condition that partial passengers are uncomfortable.
