Description

A method for adjusting comfort and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 25, 2023, with application number CN202311084907.6 and application name “A method for adjusting comfort and related devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic technology, and in particular to a comfort adjustment method and related devices. Background Art

[0003] User comfort is affected by various factors. To provide users with a more comfortable experience, comfort is generally adjusted through adjustment devices, such as using a thermostat to adjust the temperature and a wind speed regulator to adjust the wind speed.

[0004] Adjustment devices can quickly adjust the comfort level in a space. However, adjustment devices generally automatically adjust the comfort level according to the user's preset functional mode and cannot meet the user's actual needs.

[0005] Summary of the Invention

[0006] The present application provides a comfort adjustment method and related devices, which can improve the user's comfort experience.

[0007] In a first aspect, the present application provides a method for adjusting comfort, which can be applied in the field of electronic technology. The method comprises:

[0009] Compared to automatically adjusting comfort levels based on user-preset functional modes, this application adjusts comfort levels by combining environmental information, user information, and thermal comfort indicators. This achieves adaptive comfort adjustment, eliminates the need for manual user operation, and further improves the user experience. Furthermore, compared to adjusting comfort levels using a single device, this embodiment can jointly adjust multiple devices based on environmental information, user information, and thermal comfort indicators, further improving the response speed of comfort adjustment, achieving a more rapid comfort effect, and improving unit energy efficiency, saving energy.

[0124] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the device described above can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.

[0125] It can be understood that the structure of the adjustment system shown in Figures 1a and 1b is only an example. The comfort adjustment method provided in the embodiment of the present application can be applied to but not limited to the structure described above and is not limited here.

[0126] The comfort adjustment method provided in the embodiments of the present application can be applied to any non-open space such as a house, a car, a cabin (such as a sleeping cabin, a submarine, etc.), and any scenario in which the comfort is adjusted in combination with the environment and the user. The space can be a local space, in which devices with different functions are arranged, and the comfort can be jointly adjusted by adjusting different parameters between the devices. The devices can be connected via a wired or wireless connection. Alternatively, the device with different functions can also be a device that integrates multiple functions.

[0127] Example scenario 1: In-car scene

[0128] In this scenario, when a user is driving or resting in a car, the thermal environment information in the car, the user's thermal preference differences, and metabolic rate will all affect the user's comfort experience in the car. The comfort adjustment method provided in the embodiments of the present application can adjust the comfort by controlling the air conditioner, seats, window glass, etc. For example, by adjusting the air conditioner's wind speed and air volume, the seat's angle and surface temperature, the radiation transmittance of the window glass, and the body's thermal preference differences and metabolic rate, the comfort in the car can be adjusted to meet the user's comfort needs.

[0129] Example scenario 2: Sleeping scenario

[0130] In this scenario, the user is preparing to rest for a period of time. The user's thermal environment requirements may vary at different stages of sleep. The thermal environment information in the space, the user's thermal preferences during sleep, and the metabolic rate will all affect the user's comfort experience during sleep. The comfort adjustment method provided in the embodiment of the application can adjust the comfort level by controlling the air conditioner, fan, etc. to meet the user's comfort needs.

[0131] The comfort adjustment method provided in the embodiments of the present application can be applied to an adjustment system, where it is executed by a control device of the adjustment system to control multiple devices to adjust the comfort level within a space. The control device within the adjustment system can communicate with each device, and each device can communicate with each other, wirelessly or wired, to jointly control the devices within the space to adjust the user's comfort within the space.

[0132] The current mainstream comfort adjustment method generally adopts a preset automatic adjustment mode, such as the user customizes the temperature and duration in the car through the control system to keep the temperature in the car constant; or, the temperature in the car is automatically adjusted by the control system in the car to keep the room temperature constant; or, by monitoring the temperature at a specific time point, the indoor temperature is adjusted, such as automatically raising (when cooling) or lowering (when heating) the air-conditioning temperature 0.5 hours after the nap mode is turned on, or the air-conditioning temperature rises by 2°C and remains unchanged (when cooling) or falls by 2°C and remains unchanged (when heating) within 2 hours.

[0133] However, using the preset automatic adjustment mode to adjust the comfort level in the space will have the following problems:

[0134] (1) The wind speed and direction when the automatic air conditioner is turned on may not be suitable for a specific scenario. For example, in a sleeping scenario, the user may easily feel the draft in a closed environment and be easily woken up by the draft. In addition, excessive wind speed will generate noise, affecting sleep quality.

[0135] (2) Setting the temperature to a constant value cannot fully meet the thermal comfort needs of the human body during sleep and does not take into account the changes in the human body's demand for the thermal environment during sleep;

[0136] (3) The impact of changes in external environmental radiation is not taken into account. For example, in a car interior, the car body is also greatly affected by changes in the external environment compared to the interior of the car. Current technologies often ignore the impact of the external environment, resulting in unintelligent adjustments.

[0137] In order to solve the above problems, an embodiment of the present application provides a method for adjusting comfort, which can be applied to the adjustment system described in the above scenario. Specifically, please refer to Figure 1c, which is a flow chart of a method for adjusting comfort provided in an embodiment of the present application. The method specifically includes: S1. Obtaining environmental information and user information corresponding to a first space; the first space is a non-open space. S2. Determining the control index of at least one device corresponding to the first space based on the environmental information, the user information and the characterization index of thermal comfort. S3. Controlling the at least one device based on the control index of the at least one device.

[0138] It is understandable that, firstly, compared to automatically adjusting comfort levels based on user-preset functional modes, this application adjusts comfort levels by combining environmental information, user information, and thermal comfort indicators, achieving adaptive comfort adjustment, eliminating the need for manual user operation and further improving the user experience. Secondly, compared to adjusting comfort levels using a single device, this embodiment can jointly adjust multiple devices based on environmental information, user information, and thermal comfort indicators, thereby further improving the response speed of comfort adjustment, achieving a more rapid comfort effect, and improving unit energy efficiency, saving energy consumption.

[0139] The above introduces the application scenarios of the comfort adjustment method provided in the embodiment of the present application. The following describes in detail the implementation process of the comfort adjustment method provided in the embodiment of the present application.

[0140] First, in order to better understand the solutions of the embodiments of the present application, the relevant terms and concepts that may be involved in the embodiments of the present application are introduced below.

[0141] (1) Average thermal sensation index

[0142] The Predicted Mean Vote (PMV) is an indicator that reflects the human body's perception of heat and cold. It represents the average temperature people experience in the same environment. For example, the PMV can be divided into seven comfort rating levels: -3 (cold), -2 (cool), -1 (slightly cool), 0 (comfortable), +1 (slightly warm), +2 (warm), and +3 (hot).

[0143] (2) Expected dissatisfaction percentage

[0144] The predicted percentage dissatisfaction (PPD) indicates the percentage of people who are dissatisfied with the thermal environment, that is, the percentage of the population who are dissatisfied with the thermal environment.

[0145] Please refer to Figure 2, which is another schematic flow diagram of a comfort adjustment method provided in an embodiment of the present application. This comfort adjustment method can be executed by a control device of an adjustment system. As shown in Figure 2, the control device can perform the following steps 201 to 205 to improve the user's comfort experience.

[0146] Step 201: The control device obtains environment information and user information corresponding to the first space.

[0147] In the embodiment of the present application, the first space mainly refers to the non-open space as exemplified above. Environmental information mainly refers to the current environment and relevant parameter information of the equipment. Among them, the equipment mainly refers to the relevant equipment for adjusting parameters. For example, equipment such as air conditioners or fans that adjust air volume, wind speed, wind direction, and air temperature, and humidity control equipment that adjusts relative humidity. Corresponding to different application scenarios, for example, in a car, the equipment may include on-board air conditioners, fans, seats (which can be used to adjust the temperature of the seat surface), window glass (which can be used to adjust the transmittance of sunlight), etc. In an optional implementation method, the environmental information includes at least one of air temperature, relative humidity, average radiant temperature, wind speed, air volume, wind direction, noise, and surface temperature of the equipment.

[0148] In this implementation, air temperature primarily refers to the air temperature inside and outside the space and around the user. It should be understood that the comfort adjustment method provided in the embodiments of this application is primarily intended to improve the user's comfort experience. Therefore, it is necessary to consider the temperature, humidity, mean radiant temperature, wind speed, air volume, wind direction, noise, and other factors surrounding the user. Wind speed primarily refers to the change in wind speed around the human body. Radiation primarily refers to the solar radiation and net longwave radiation received by the human body, which can be characterized by the mean radiant temperature.

[0149] It is understandable that, in actual application, the specific content of the environmental information can be set according to actual needs or experiments. For example, it can also include the direction of the fan blades, etc., which is not limited here.

[0150] In an optional implementation, the user information includes: user behavior information and user thermal comfort information.

[0151] User behavior information includes the stage of the user's behavior activity;

[0152] The user's thermal comfort information includes at least one of the following: the user's clothing, bedding or other body surface covering information, physiological indicators, metabolic rate, age or comfort preference.

[0153] In this implementation, user behavior information primarily includes the stage of the user's activity. Users may have different needs and preferences at different stages of their activity. The control device adjusts the comfort level based on this information, helping to improve the user's comfort experience. User thermal comfort information primarily refers to information related to the user's thermal sensation.

[0154] The user's behavior and activity stage can be obtained based on user-set data or one or more devices such as wearable devices, cameras, and sensors. This includes, for example, determining the user's nap stage based on the user-set sleep mode start time and duration, the wearable device's determination of the user's sleep time and duration, actions such as eye closing detected by the camera, breathing rate detected by the microphone, and the pressure sensor's detection of the user's pulse, breathing, body movements, and staying in bed.

[0155] It is understood that the control device can adjust the comfort level based on the user's behavioral information and the user's thermal comfort information. The user's comfort preference can be derived based on user-preset parameters and / or current environmental parameters, or based on historical data. User comfort preferences are divided into subjective preferences and objective preferences. Subjective preferences primarily refer to the user's own requirements for comfort, for example, a user is more comfortable at a certain temperature or wind speed. Objective preferences primarily refer to relevant information that can improve the user's comfort experience more quickly or more effectively based on actual experiments or theoretical data.

[0156] Optionally, the user's behavioral activity is taking a nap.

[0157] The user's behavior activities include different stages. For example, assuming that the user is taking a nap, the user may be in one of the three stages: before falling asleep, falling asleep, and the end of sleep / about to wake up.

[0158] Optionally, the at least two stages of behavioral activity include at least two of: before falling asleep, during sleep, and at the end of sleep. It should be understood that the user's thermal comfort information and environmental information may be different in different behavioral stages. Taking the sleep scene as an example, the wind speed around the human body before and after falling asleep, the sunlight radiation and net long-wave radiation received by the human body before and after falling asleep, the changes in the human body's metabolic rate before, during, and after sleep, and the thermal resistance information of clothing and bedding before and after falling asleep may all be different. The embodiments of this application are for illustrative purposes only and are not limiting.

[0159] Step 202: The control device adjusts the comfort index according to the user information to obtain an adjusted comfort index.

[0160] In an embodiment of the present application, after obtaining an initial comfort indicator, the control device can adjust the comfort indicator based on user information to meet the user's comfort requirements for different stages of behavioral activities and different scenarios. The comfort indicator is primarily used to represent the user's evaluation of comfort. Because users have different comfort requirements at different stages of their behavioral activities, the control device primarily adjusts the comfort indicator based on the user's behavioral information.

[0161] Compared with adjusting the comfort level based on the comfort level characterization indicators directly set or defaulted by the user, or only based on the comfort level characterization indicators at individual time points of the user's different behavioral activities, the embodiment of the present application adjusts the comfort level characterization indicators in stages based on the stages of the user's different behavioral activities, and matches them with the user's actual thermal needs, thereby further improving the user's comfort experience.

[0162] In an optional implementation, the control device may obtain a characterization index of comfort based on historical data and experimental results.

[0163] The control device may obtain general setting values ​​for the comfort index based on historical empirical data, experimental data, or theoretical literature. Optionally, the control device may also set corresponding change curves based on the comfort index corresponding to different stages, so as to set corresponding comfort indexes for different stages.

[0164] In an optional implementation, the comfort indicator includes PMV.

[0165] In this implementation, taking sleeping behavior as an example, the comfort index can be determined by the different stages of the user's nap, among which the different stages of the user's nap can be determined based on the start and end time, duration, state of falling asleep, and behavior such as staying in bed set by the user.

[0166] The PMV value may vary during different sleep stages. For details, see Figure 3, which is a distribution curve of the PMV values ​​of a user during sleep, provided by an embodiment of the present application. The PMV value can be set based on the following reasons.

[0167] (1) The first stage (before falling asleep): a warm environment within the thermal comfort range, which reduces the temperature difference between the distal and proximal ends of the user's skin and promotes falling asleep (taking PMV as an example, PMV = 0.5);

[0168] (2) The second stage (falling asleep): maintaining thermal comfort, and the sleep quality is higher in a thermally neutral environment (taking PMV as an example, PMV = 0);

[0169] (3) The third stage (late sleep stage / about to wake up): a cool environment within the thermal comfort range, which reduces the probability of sleep inertia (taking PMV as an example, PMV = -0.5).

[0170] The first stage (before falling asleep) begins when the user manually activates nap mode. Alternatively, the device can determine the starting point, such as when the user lies down, closes their eyes, or changes from motion to stillness. The first stage ends when the user is determined to be asleep, for example, by capturing their behavior through a camera or other device.

[0171] The starting point of the second stage (falling asleep) is the end point of the first stage. The end point of the second stage can be determined according to the end point of the nap mode. For example, if the end point of the nap is 3 pm, the end point of the second stage is a fixed time in advance of the end point of the nap (for example, 5 minutes in advance); the end point of the nap mode can be set manually by the user; the end point of the second stage can also be determined based on the user status. For example, if the user wakes up early, the nap mode ends early and there is no need to enter the third stage.

[0172] The third stage (the end of sleep) defaults to the end of the nap. The end of the third stage can also be determined based on the user's state. For example, if the user turns off the alarm and continues to sleep, the end of the third stage will be adjusted, extending the third stage.

[0173] In practical applications, comfort is currently typically adjusted based on the default PMV value, failing to dynamically adjust comfort based on the user's actual needs and environmental information, resulting in a poor user comfort experience. In this embodiment, the control device can adjust the PMV value based on the user's current activity stage to more accurately match the user's comfort needs.

[0174] In addition, the stage of the user's behavioral activity can be adjusted according to actual conditions, and does not change in a specified time sequence. The control device can adjust the stage of the user's behavioral activity according to actual needs, so as to determine a more accurate PMV target value. For example, assuming that the user is in the third stage, the user turns off the alarm clock and continues to sleep for 10 minutes. In order to ensure the user's sleep quality, the control device can set the user's nap stage to the second stage in the first 5 minutes of the set 10 minutes. Correspondingly, the control device sets the PMV target value to the value corresponding to the second stage. In the last 5 minutes, in order to enable the user to overcome sleep inertia, the control device can set the PMV target value to the value corresponding to the third stage to reduce the user's sleep inertia.

[0175] It's understood that PMV values ​​can also be set based on user-defined heating and cooling preferences. If a user frequently adjusts the temperature manually over a period of time, the control device can collect relevant user data and adapt historical operations to meet user preferences. Furthermore, PMV values ​​at different stages may not only be related to the user's thermal preferences and usage habits, but also to the user's demographic, such as the elderly, children, pregnant women, and patients with medical conditions. These values ​​can be set based on actual needs.

[0176] Optionally, comfort indicators may also include equivalent homogeneous temperature (EHT), dynamic thermal sensation index (DTS), thermal perception index, etc., which are not limited here.

[0177] It is understandable that the control device can select corresponding comfort characterization indicators according to different scenarios and needs.

[0178] Step 203: The control device determines a functional relationship of a control index of at least one device corresponding to the first space according to the environmental information, the user information, and the adjusted comfort representation index.

[0179] In the embodiment of the present application, the functional relationship of the control index of at least one device corresponding to the first space mainly refers to the functional relationship between the target values ​​or target ranges of the control index corresponding to each of the at least one device.

[0180] The specific composition of each device and the target value or target range of the control indicator corresponding to each device can be determined based on environmental information and user information. For example, assuming that the environmental information includes wind speed, relative humidity, and seat surface temperature, the control device can control the air conditioner or fan, humidity control device, and seat heating device to adjust the wind speed, relative humidity, and seat surface temperature to target values ​​or target ranges that meet the comfort requirements based on the user's behavior information at different stages, the user's comfort requirements, and other constraints. In the above example, the devices may include an air conditioner or fan, and a humidity control device, and the control indicators to be adjusted corresponding to each device may include the target value of wind speed adjusted by the air conditioner or fan, the target value of relative humidity adjusted by the humidity control device, and the target value of seat surface temperature adjusted by the seat heating device.

[0181] Additionally, at a given moment, the control device can derive a functional relationship between the target values ​​of the control indicators corresponding to at least one device at that moment based on the parameter information corresponding to that moment. Within a given time period, the control device can derive a functional relationship between the target values ​​of the control indicators corresponding to at least one device within that period based on the average parameter information within that period.

[0182] It is understandable that in actual applications, each device and its corresponding control indicators can be set according to actual needs or experiments. In different application scenarios and different needs, the type of equipment and control indicators have certain differences. The embodiments of this application are only illustrative and not limiting.

[0183] In an optional implementation, the at least one device includes at least two devices;

[0184] The control device determines a control index of at least one device corresponding to the first space based on the environmental information, the user information, and the thermal comfort indicator, including:

[0185] A functional relationship between control indicators of at least two devices corresponding to the first space is determined based on the environmental information, the user information and the characterization index of thermal comfort.

[0186] In this implementation, the control device jointly adjusts multiple devices based on environmental information, user information and thermal comfort characterization indicators, thereby further improving the response speed of comfort adjustment and achieving a comfortable effect more quickly.

[0187] In an optional implementation, the control device inputs environmental information, user information, and the adjusted thermal comfort index into a first model to determine a control index of at least one device corresponding to the first space.

[0188] In this implementation, the control device may input environmental information, user information, and the adjusted thermal comfort index into a pre-set first model to determine the control index of at least one device corresponding to the first space.

[0189] In actual applications, if the control device wants to add a new device to jointly adjust the comfort with other devices, in some cases, the control device may also need to add a calculation item about the device in the first model to combine the parameter indicators of other devices included in the first model for joint calculation to obtain the functional relationship between the control indicators corresponding to each device.

[0190] It should be understood that when calculating the control index of a single device based on the first model, since the unknown quantity is unique, the first model outputs the control index of the single device. When calculating the control index corresponding to multiple devices based on the first model, due to the addition of calculation items for the specified device in the first model, there are multiple unknown quantities, and a unique solution cannot be obtained. Therefore, the first model outputs a functional relationship based on the control index corresponding to the multiple devices. For example, to avoid a drafty feeling and noise, in addition to controlling the air conditioner, if the control device determines based on internal and external environmental information and device information that seat heating is needed to adjust the comfort level in conjunction with the air conditioner, the control device can measure the size and temperature of the current seat surface in contact with the human body and, based on the measured parameters, add a conductive heat term (corresponding to the calculation item for the seat surface temperature) to the first model. After the control device inputs the environmental information, user information, the adjusted comfort indicator, and the current seat surface temperature into the first model, it outputs a functional relationship between the target value of the air temperature under comfort conditions and the target value of the seat surface temperature.

[0191] In an optional implementation, the control device may obtain environmental parameters inside and outside the vehicle and device information inside the vehicle to determine the devices involved in comfort adjustment.

[0192] In this implementation, optionally, the first model includes a PMV-PPD thermal comfort model.

[0193] Optionally, the first model includes an EHT equivalent temperature model, a Fiala DTS thermal comfort model, etc.

[0194] For example, taking the first model as the PMV-PPD thermal comfort model, and adding a conductive heat term to the first model, the formula of the first model is: PMV=(0.303e -0.036M +0.0275)L=(0.303e -0.036M +0.0275)*(MWCRE)

[0195] Among them, L is the heat load, M is metabolic heat production, W is external work, C is convective heat transfer, R is radiation heat transfer, and E is evaporative respiration heat transfer.

[0196] A new heat conduction term related to the seat surface temperature is added to the first model. The formula of the first model is: PMV=(0.303e -0.036M +0.0275)L=(0.303*e -0.036M +0.0275)*(MWCREQ)

[0197] Where L is the heat load, Q is the conduction heat transfer term, and is a function of the seat surface temperature T and the temperature difference ΔT between the skin and the seat surface, where skin refers to the skin of the user in contact with the seat surface.

[0198] Optionally, the expression for Q is:

[0199] Where S is the seat contact area fraction, I cl is the thermal resistance of clothing.

[0200] It should be noted that the above formula is only one example. The specific content of the formula and the content of the newly added calculation items can be set according to actual needs and are not limited here.

[0201] Step 204: The control device obtains a control index corresponding to at least one device according to the functional relationship.

[0202] In an embodiment of the present application, after the control device determines the functional relationship of the control indicators of at least one device corresponding to the first space in combination with environmental information, user information and the characterization indicators of the user's comfort at different stages, it can further calculate the control indicators corresponding to at least one device.

[0203] The control indicator corresponding to at least one device refers to a target value or target range for the control indicator corresponding to the at least one device. Since comfort adjustment requires consideration of the current actual environmental requirements, user needs, and other information, in actual applications, if any set of solved values ​​in the functional relationship between the control indicators corresponding to the at least one device meets the requirements, multiple sets of parameter values ​​that meet the requirements can be directly determined from the functional relationship based on the actual situation.

[0204] Optionally, the control device obtains a control index corresponding to at least one device according to the first constraint and the functional relationship.

[0205] It is understood that the first constraint refers to constraint information corresponding to the actual environment and user needs. If certain constraints exist, the control device can limit the value range of the control indicators corresponding to at least one or more devices in accordance with the first constraint, thereby further obtaining a result that satisfies the conditions based on the functional relationship between the control indicators corresponding to the at least one device.

[0206] In an optional implementation, the first constraint includes at least one of an environment constraint, a user constraint, a device constraint, and an energy consumption constraint.

[0207] In this implementation, the control device may select a control indicator that meets the requirements from the functional relationship between the control indicators corresponding to at least one device in combination with the first constraint.

[0208] The first constraint includes constraints across multiple dimensions. Environmental constraints can include indicators such as temperature and humidity inside and outside the space, as well as around the human body. For example, to avoid a draft sensation, a draft sensation index can be calculated based on environmental information such as temperature and wind speed distribution. If the draft sensation index exceeds a threshold, the wind speed is reduced to below the threshold and the new wind speed value is substituted into the first model. For example, if the temperature difference between inside and outside is too large, the air conditioner may need to use a higher wind speed setting (also a device constraint) to ensure that the interior of the space can be cooled or heated to a comfortable target temperature in a timely manner. However, this can cause excessive wind noise and a noticeable draft sensation, necessitating coordination with other devices such as seat ventilation / heating. Alternatively, for example, the noise level inside the vehicle should not exceed 35dB, and the relative humidity should not exceed 65%. User constraints can include user preferences. For example, different users have different needs or preferences for draft sensation, relative humidity (for example, asthma patients have certain relative humidity requirements), and sunlight radiation tolerance. Device constraints can include device noise levels and wind direction levels. For example, to avoid air conditioner noise, the control device can determine the noise level based on the wind speed setting. If the noise exceeds a threshold, the wind speed is reduced to below the threshold and the new wind speed value is substituted into the first model. For example, whether the current device is available, how the device responds to the current vehicle interior and exterior environment (whether it generates noise or excessive drafts), etc. Energy consumption constraints are primarily considered from the perspective of energy consumption, and corresponding constraints can be set based on actual energy consumption requirements.

[0209] In an optional implementation, the at least one device includes at least two devices;

[0210] The control device determines the control indicators of the at least two devices according to the functional relationship between the control indicators of the at least two devices corresponding to the first space.

[0211] In this implementation method, after the control device determines the functional relationship between the control indicators of at least two devices corresponding to the first space by combining environmental information, user information and the characterization indicators of the user's comfort at different stages, it can further calculate the control indicators corresponding to at least two devices.

[0212] In this implementation, optionally, the control device determines the control indicators of the at least two devices according to the functional relationship between the first constraint and the control indicators of the at least two devices corresponding to the first space.

[0213] It can be understood that in actual applications, assuming that the control device jointly controls three devices to adjust the comfort, the control device generally determines the target value range of the parameters of two of the devices based on the first constraint, and then determines the target value range of the remaining device parameters based on the functional relationship.

[0214] Step 205: The control device controls at least one device according to the control indicator of the at least one device.

[0215] In an embodiment of the present application, after determining a control index for at least one device, the control device may control the at least one device based on the control index. For example, the control device may adjust the air conditioner based on a change in the air conditioner's set temperature, adjust the seat based on the seat surface temperature, heating level, and time, or adjust the seat based on the seat's ventilation level.

[0216] In an optional implementation, the control index of at least one device includes at least one of the following: air temperature, relative humidity, wind speed, wind direction, device surface temperature, or glass transmittance.

[0217] In this implementation, the control index of at least one device may include multiple parameters, and different parameters may correspond to different devices. For example, after determining the control index of at least one device, the control device can control air conditioners and other devices according to the air temperature, control humidity control devices according to the relative humidity, control air conditioners or electric fans and other devices according to the wind speed and wind direction, adjust seats and other devices according to the surface temperature of the device, and adjust glass and other devices according to the refractive index of the glass. In addition, the surface temperature of the device includes not only the temperature of the seat surface, but also the temperature of the surface of other devices with heat radiation functions, such as infrared heat radiators (such as electric heaters, etc.).

[0218] In an optional implementation, the at least one device includes at least two devices;

[0219] The control device controls the at least two devices respectively according to the control indicators of the at least two devices.

[0220] In this implementation, the control device can control at least two devices separately according to the control indicators of the at least two devices, so as to jointly adjust the user's comfort based on multiple devices, further improving the adjustment efficiency and saving energy consumption to a certain extent.

[0221] In order to more clearly understand the comfort adjustment method provided in the embodiment of the present application, it is introduced below with reference to specific examples.

[0222] Example Scenario 1

[0223] At lower temperatures, thermal comfort in a closed environment is controlled using only air conditioning. Consider a winter day with a temperature of -15°C in a basement with no sunlight or heating. A person enters a vehicle wearing winter clothing, removes their coat, and then dons indoor winter clothing (1clo) for a 45-minute nap. The initial temperature inside the vehicle is similar to the outside temperature.

[0224] In this scenario, due to the low temperatures inside and outside the vehicle, relying solely on air conditioning to raise the temperature can result in long heating times, excessive air speeds, excessive noise, and high energy consumption. To avoid these issues, such as drafty sensations, noise, duration, and energy consumption, seat surface heating can be controlled to quickly raise the temperature inside the vehicle, meeting the user's heating needs.

[0225] To this end, an embodiment of the present application provides a method for adjusting comfort, which is primarily executed by a control device in the adjustment system. Specifically, please refer to Figure 4, which is another schematic flow chart of the comfort adjustment method provided in an embodiment of the present application. As shown in Figure 4, the method primarily includes steps 401 to 407.

[0226] Step 401: The control device obtains the environment information and user information in the vehicle.

[0227] Among them, environmental information includes air temperature inside the car, wind speed around people, relative humidity, sunlight radiation, temperature and size of the seat surface, etc.

[0228] Step 402: The control device adjusts the target value of the PMV according to the user information.

[0229] Optionally, the control device may adjust the target value of the PMV according to the user's behavior information, for example, the stage of the user's behavior activity.

[0230] Optionally, the user information includes historical user usage data (for example, air conditioning temperature for thermal comfort, equipment parameters during past sleep under similar working conditions, etc.), human metabolic rate, thermal resistance of clothing or mattress, and other information.

[0231] Step 403: The control device determines the devices involved in the adjustment according to the environmental information.

[0232] In this embodiment, the control device can combine the temperature information and other constraint information of the device to add a seat to adjust the comfort.

[0233] Understandably, due to the low temperatures inside and outside the vehicle, relying solely on air conditioning to raise the temperature can result in long heating times, excessive air speeds, excessive noise, and high energy consumption. To avoid these issues, such as drafty sensations, noise, duration, and energy consumption, seat surface heating can be controlled to quickly raise the vehicle's interior temperature and meet the user's heating needs.

[0234] There is no requirement for the execution order of step 402 and step 403.

[0235] In step 404 , the control device adds a conductive heat term corresponding to the calculated seat surface temperature in the PMV-PPD thermal comfort model in combination with the environmental information.

[0236] Step 404 is optional. The control device may pre-add a conductive heat term corresponding to the calculated seat surface temperature to the PMV-PPD thermal comfort model based on environmental information. After obtaining information such as the seat surface temperature and size, the control device directly inputs this information into the PMV-PPD thermal comfort model with the added conductive heat term, outputting a functional relationship between air temperature and seat surface temperature that meets thermal comfort targets for different sleep stages. Alternatively, the control device may combine current environmental information with the addition of a conductive heat term corresponding to the calculated seat surface temperature to the PMV-PPD thermal comfort model before proceeding to the next step of the calculation.

[0237] In step 405 , the control device brings the environmental information and the user information into the PMV-PPD thermal comfort model to obtain a functional relationship between the air temperature and the seat surface temperature that meets the thermal comfort target at different sleep stages.

[0238] In step 406 , the control device obtains control indicators corresponding to the air conditioner and the seat according to the constraint conditions and the functional relationship between the air temperature and the seat surface temperature.

[0239] In this step, the control device can set a lower target air temperature (such as 20°C) to keep the wind speed moderate, based on the equipment design principles and energy consumption constraints. Then, according to the determined target air temperature range, the target seat human contact surface temperature range (30-36°C) is output based on the functional relationship, and the seat heating is turned on to switch to the insulation mode after reaching the target temperature range.

[0240] In step 407 , the control device adjusts the air conditioner and the seat respectively according to their corresponding control indicators.

[0241] Example Scenario 2

[0242] Thermal comfort is controlled in a closed environment with high relative humidity. For example, consider a rainy day with an ambient temperature of 28°C. A user wearing summer clothing takes a 45-minute nap in a closed environment with the initial temperature and relative humidity comparable to the outside environment.

[0243] In this scenario, due to the high relative humidity in the environment, in addition to adjusting the temperature, it is also necessary to use humidity control equipment to adjust the relative humidity to solve the problem of excessive relative humidity, thereby further improving the user's comfort experience.

[0244] To this end, an embodiment of the present application provides a method for adjusting comfort, which is primarily executed by a control device in the adjustment system. Specifically, please refer to Figure 5, which is another schematic flow chart of the comfort adjustment method provided in an embodiment of the present application. As shown in Figure 5, the method primarily includes steps 501 to 507.

[0245] Step 501: The control device obtains environmental information and user information.

[0246] Environmental information includes air temperature, wind speed around the user, relative humidity, etc. User information includes historical user usage data (for example, air conditioning temperature for thermal comfort, device parameters during previous sleep under similar working conditions, etc.), human metabolic rate, and thermal resistance of clothing or mattresses.

[0247] It is understandable that the thermal resistance information of the user's clothing or mattress will affect the air temperature of the user during sleep.

[0248] For example, please refer to Figure 6a, which is a schematic diagram illustrating the change in air temperature during different sleep stages when a user is wearing summer clothing, according to an embodiment of the present application. Assuming the user is wearing summer clothing and the air temperature before falling asleep is T, during sleep, the user's metabolic heat production decreases. To ensure thermal comfort and prevent the user from catching a cold, the temperature T may continue to rise. To reduce sleep inertia at the end of sleep, the temperature may be lowered to help the user wake up faster and avoid sleep inertia.

[0249] Please refer to Figure 6b, which is a schematic diagram of the change in air temperature during different sleep stages when the user covers themselves with a quilt, as provided in an embodiment of the present application. Assuming that the user covers themselves with a 0.5clo quilt and the air temperature before falling asleep is T, during the user's sleep, in order to ensure the user's thermal comfort needs and prevent the user from feeling too hot due to reduced heat dissipation after covering themselves with the quilt, the temperature T may drop (by 0.5°C). At the end of the sleep phase, in order to reduce the user's sleep inertia, the temperature can be further lowered (by 1°C) to help the user wake up as soon as possible.

[0250] Step 502: The control device adjusts the target value of the PMV according to the user information.

[0251] Step 503: The control device determines the devices involved in the adjustment according to the environmental information.

[0252] The control device may combine temperature information, humidity information and other constraint information of the device to add a humidity adjustment device to adjust the comfort level.

[0253] It is understandable that, due to the high relative humidity in the environment, in addition to adjusting the temperature, it is also necessary to use humidity adjustment equipment to adjust the relative humidity in order to solve the problem of excessive relative humidity.

[0254] There is no requirement for the execution order of step 502 and step 503.

[0255] Step 504: The control device selects the PMV-PPD thermal comfort model based on environmental information.

[0256] In this step, since the first model includes parameters of relative humidity, the control device does not need to add additional parameters and calculation items related to relative humidity. The control device selects the PMV-PPD thermal comfort model for calculation based on environmental information.

[0257] In step 505 , the control device brings the environmental information and user information into the PMV-PPD thermal comfort model to obtain a functional relationship between air temperature, wind speed, and relative humidity that meets the thermal comfort target in different sleep stages.

[0258] Step 506: The control device obtains control indicators corresponding to the air temperature, wind speed, and relative humidity according to the constraint conditions and the functional relationship between the air temperature, wind speed, and relative humidity.

[0259] In this step, the control device can set a lower target air temperature (such as 24°C) that makes the wind speed moderate, and a target wind speed range, in combination with equipment design principles and energy consumption constraints. Based on the determined air temperature and wind speed range, the control device further outputs a target ambient humidity range (40%-60% rh), turns on the ambient dehumidification function, and maintains a constant relative humidity after reaching the target humidity range.

[0260] Step 507: The control device adjusts the air conditioner and the humidity control device respectively according to their corresponding control indicators.
