[0021] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numbers in different drawings denote the same or similar elements / function. Although various aspects of embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically noted.

[0022] As used herein, the terms "comprise", "comprising", "have", "having", "include", "including", "contain", "containing", or variants thereof, are open-ended, and include one or more stated features, integers, elements, steps, components or functions but do not preclude the presence or addition of one or more other features, integers, elements, steps, components, functions or groups thereof.

[0023] When an element is referred to as being "connected", "coupled", "responsive", or "related" to another element, it can be directly connected, coupled, responsive, or related to the other element, or intervening elements can be present.

[0024] Although the terms first, second, third, etc. can be used herein to describe various elements / operations, these elements / operations should not be limited by these terms. These terms are only used to distinguish one element / operation from another element / operation. Thus, a first element / operation in some embodiments can be termed a second element / operation in other embodiments without departing from the teachings of the present inventive concept.

[0025] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0026] The term "and / or", used in the context of describing certain implementations of the present inventive concept, refers to a conjunctive set of relationships that includes any or all of the following: A and / or B may, for example, represent the following three cases: A alone, A and B together, and B alone. In addition, the term "at least one of", used in the context of describing certain implementations of the present inventive concept, refers to any one of a plurality of items or any combination of at least two of the plurality of items, for example, including at least one of A, B, and C may, for example, refer to a selection of any one or more elements from a set consisting of A, B, and C.

[0027] In addition, for the purpose of convenience and brevity, detailed descriptions of well-known functions and structures incorporated herein can not be described in detail and are deemed as familiar to one skilled in the art. In some instances, well-known methods, structures, and techniques have not been described in detail in order to avoid obscuring the subject matter of the present inventive concept.

[0028] As vehicles such as automobiles become increasingly electrified, intelligent, and comfortable, people's demands for thermal comfort within vehicle cabins (e.g., car seats) are also rising. Currently, the regulation of the thermal environment within a vehicle cabin primarily relies on the driver or passengers controlling the vehicle's air conditioning system to meet their temperature preferences. While this method allows for flexible temperature control, it suffers from low levels of automation and intelligence. Passengers must manually adjust the temperature using buttons or voice commands while the vehicle is in motion, which can negatively impact their driving or riding experience. Furthermore, for the driver, this temperature control method can be distracting, potentially creating safety hazards.

[0029] On the other hand, when the vehicle's air conditioning system is set to a fixed temperature for a long time, or when the occupants set the temperature of the vehicle's air conditioning system in an unreasonable way, it will increase the vehicle's energy consumption, reduce energy utilization efficiency, and thus increase the vehicle's operating costs.

[0030] In view of this, this disclosure provides a method for regulating the temperature of a vehicle compartment, which fully considers the individualized thermal comfort needs of different occupants, effectively improves the thermal comfort of each occupant, and eliminates the need for manual intervention by occupants in the temperature adjustment process. This reduces the probability of unreasonable air conditioning settings, improves the energy efficiency of the target vehicle, and lowers the operating costs of the target vehicle. The method for regulating the temperature of a vehicle compartment provided in this disclosure is described in detail below.

[0031] Figure 1 A flowchart illustrating a method for regulating the temperature of a vehicle compartment according to an embodiment of this disclosure is provided. This method can be executed by an electronic device such as a terminal device or a server. The terminal device can be a user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, in-vehicle device, wearable device, etc. The method can be implemented by a processor calling computer-readable instructions stored in memory. Alternatively, the method can be executed by a server. Figure 1 As shown, the method for controlling the temperature of the vehicle's compartment includes:

[0032] In step S101, the thermal neutral temperature of the target vehicle is determined based on the ambient temperature outside the target vehicle and the solar radiation intensity inside the vehicle.

[0033] The target vehicle can refer to any kind of vehicle with a sealable manned cabin and a temperature regulation system such as air conditioning inside the cabin. Its specific form can be flexibly set according to actual usage needs. For example, the target vehicle can be a car, a new energy vehicle, a manned aircraft, etc. This disclosure does not make specific limitations in this regard.

[0034] The external ambient temperature of the target vehicle can represent the ambient temperature outside the manned compartment of the target vehicle. Specific methods for determining the external ambient temperature of the target vehicle can be found in related technical embodiments, and this disclosure does not impose specific limitations on them.

[0035] In one example, when the target vehicle is a car, a temperature sensor can be installed outside the car's passenger compartment to measure the ambient temperature in real time.

[0036] In one example, when the target vehicle is a car, the average local temperature can be queried online via an internet platform based on the car's current geographical location, and used as the external ambient temperature.

[0037] The solar radiation intensity inside the target vehicle's cabin, reflecting the energy of solar radiation inside the manned cabin, can be determined by a solar radiation sensor installed inside the target vehicle. The specific form of the solar radiation sensor can be found in related technologies, and this disclosure does not impose specific limitations on it.

[0038] Based on the ambient temperature outside the target vehicle and the solar radiation intensity inside the vehicle, the thermal neutral temperature of the target vehicle can be determined to reflect the temperature required to initially meet the normal physiological metabolism and thermal comfort of each occupant in the manned cabin of the target vehicle.

[0039] The following sections, in conjunction with possible implementations of this disclosure, will provide a detailed explanation of the process for determining the thermal neutral temperature of the target vehicle based on the external ambient temperature and the internal solar radiation intensity of the target vehicle; these details will not be elaborated upon here.

[0040] In step S102, based on the thermal neutral temperature, the cabin air conditioning of the target vehicle is used to adjust the real-time cabin temperature until the real-time cabin temperature meets the first preset condition.

[0041] Based on the thermal neutral temperature of the target vehicle, the real-time temperature inside the target vehicle's cabin can be regulated using the vehicle's in-cabin air conditioning system until the real-time temperature meets a first preset condition. This ensures that the real-time temperature inside the cabin initially meets the normal physiological metabolic and thermal comfort needs of the occupants. Furthermore, by utilizing the thermal neutral temperature, the influence of the cabin's solar radiation intensity can be incorporated into the temperature regulation process. Compared to temperature regulation methods that only consider the real-time cabin temperature, this improves the accuracy and comprehensiveness of cabin temperature regulation. The specific form of the in-cabin air conditioning system can be referenced from implementation methods in related technologies, and this disclosure does not impose specific limitations on it. The specific content of the first preset condition can be flexibly set according to actual usage requirements, and this disclosure does not impose specific limitations on it.

[0042] In one possible implementation, the first preset condition may include: the real-time temperature inside the cabin is within a first preset temperature range with thermal neutral temperature as the midpoint. The specific value of the first preset temperature range can be flexibly set according to actual usage requirements, and this disclosure does not impose specific limitations on it.

[0043] In one example, the first preset temperature range can be set to thermal neutral temperature ±1.5°C.

[0044] Real-time temperature T inside the cabin in < Thermal neutral temperature T neuin At -1.5℃, the real-time temperature T inside the cabin can be determined. in The first preset condition is not met, and it is necessary to set the cabin air conditioning to heating mode to increase the real-time cabin temperature T. in .

[0045] Real-time temperature T inside the cabin in > Thermal neutral temperature T neuin At +1.5℃, the real-time temperature T inside the cabin can be determined. in The first preset condition is not met, and the cabin air conditioning needs to be set to cooling mode to reduce the real-time cabin temperature T. in .

[0046] At thermal neutral temperature T neuin -1.5℃≤Real-time cabin temperature T in ≤ Thermal neutral temperature T neuin At +1.5℃, it can be determined that the real-time temperature inside the cabin meets the first preset condition, and there is no need to start the cabin air conditioning.

[0047] Through the above process, the real-time temperature inside the target vehicle can be initially adjusted based on the thermal neutral temperature, which can initially meet the normal physiological metabolic and thermal comfort needs of each occupant, reduce the probability of unreasonable setting temperature of the cabin air conditioning, thereby improving the energy utilization efficiency of the target vehicle, reducing the operating cost of the target vehicle, and providing a basis for subsequent personalized temperature adjustment for each occupant.

[0048] In step S103, if the real-time temperature inside the cabin meets the first preset condition, the infrared image of the target occupant's face in the target vehicle is input into the target thermal expectation prediction model to determine the thermal expectation prediction result of the target occupant. The thermal expectation prediction result is used to indicate the temperature adjustment needs of the target occupant.

[0049] The target occupant can refer to any person in the manned compartment of the target vehicle, such as the driver or a passenger. It can be flexibly set according to actual usage needs, and this disclosure does not make specific limitations in this regard.

[0050] Typically, even when the real-time temperature inside the target vehicle's cabin meets the first preset condition, the individual differences in human temperature perception and the inherent thermal non-uniformity within the cabin mean that the real-time temperature may not simultaneously meet the personalized thermal comfort needs of different occupants. Therefore, a target thermal expectation prediction model can be used to perform targeted thermal expectation analysis on the facial infrared images of the target occupants. This analysis determines the predicted thermal expectations of the target occupants and identifies whether they require further temperature adjustments. This ensures that secondary temperature regulation can be performed on the target occupants without requiring manual intervention from them.

[0051] The target thermal expectation prediction model can be a thermal expectation prediction model pre-trained separately for each target occupant, with each common occupant of the target vehicle having their own corresponding thermal expectation prediction model; or it can be a general thermal expectation prediction model used uniformly for all occupants.

[0052] The specific form of the target heat expectation prediction model can be referred to the implementation methods in related technologies. For example, the target heat expectation prediction model can be a selective structured state space model built based on the Mamba algorithm. This disclosure does not specifically limit it.

[0053] The specific content of the thermal expectation prediction results can be flexibly set according to actual usage needs. For example, it may include whether there is a need for temperature adjustment or not. This disclosure does not make specific limitations on this.

[0054] For specific methods of determining the facial infrared image corresponding to the target occupant, refer to the implementation methods in related technologies; this disclosure does not impose any specific limitations on them.

[0055] In one example, an infrared thermal imaging camera can be installed inside the target vehicle, and combined with the vehicle's onboard computer, to determine the facial infrared image of any occupant within the passenger compartment. The specific form of the infrared thermal imaging camera can be found in related technologies, and this disclosure does not impose specific limitations on it.

[0056] Through the above process, the corresponding thermal expectation prediction results can be automatically analyzed based on the facial infrared image of each occupant. Then, personalized temperature adjustment can be performed for occupants whose thermal expectation prediction results indicate a need for temperature adjustment, without requiring manual temperature adjustment by the occupant. When the occupant is the driver, the impact on vehicle driving can be reduced, and driving safety can be improved.

[0057] In step S104, if the thermal expectation prediction result indicates a need for temperature adjustment, the thermal comfort of each target part is determined based on the real-time temperature of the area corresponding to each target part of the target occupant.

[0058] Typically, different body parts of the same person experience significant differences in temperature sensation. Furthermore, variations in clothing coverage further influence temperature sensation across different body parts. For example, in an environment of the same temperature, the temperature sensation of unclothed areas like the hands and head will often differ, while the temperature sensation of covered areas like the feet and abdomen will also differ depending on the degree of clothing application. Therefore, under the same ambient temperature, the thermal comfort of different body parts will vary. If the thermal expectation prediction indicates a need for temperature adjustment, it can be determined that at least one body part of the target occupant has low thermal comfort and requires targeted temperature regulation for that area.

[0059] Specifically, the real-time temperature of each target part of the target occupant can be determined separately, and the thermal comfort of different target parts of the target occupant can be analyzed to facilitate targeted temperature adjustment for different target parts. The specific number of target parts and the specific location of each target part can be flexibly set according to actual usage needs, and this disclosure does not impose specific limitations on them.

[0060] In one example, each target occupant can be configured to have three target areas: the head area, the waist and abdomen area, and the foot area. The specific coverage area of ​​each target area can be flexibly set according to actual usage needs, and this disclosure does not impose specific limitations on it.

[0061] For specific methods to determine the real-time temperature of the area corresponding to any target location, refer to the implementation methods in related technologies; this disclosure does not impose any specific limitations on them.

[0062] In one example, multiple temperature sensor groups can be installed in the manned compartment of the target vehicle, where any one temperature sensor group is used to monitor the temperature of a target part of a occupant in real time; the number of temperature sensors included in any one temperature sensor group depends on the specific number of target parts. The specific form of any one temperature sensor can refer to the implementation methods in related technologies, for example, it can be set as an infrared temperature sensor, etc., and this disclosure does not specifically limit it in this regard.

[0063] The thermal comfort of any target location can quantitatively reflect the satisfaction of the target occupant with the real-time temperature of that target location.

[0064] The following section, in conjunction with possible implementation methods of this disclosure, details the process of determining the regional thermal comfort of each target part based on the real-time temperature of the region corresponding to each target part of the target occupant, when the thermal expectation prediction result indicates a need for temperature adjustment. This will not be elaborated upon here.

[0065] If the thermal expectation prediction results for all occupants indicate that there is no need for temperature adjustment, the cabin air conditioning can be controlled to maintain a constant real-time cabin temperature, and facial infrared images of each occupant can be continuously collected. If the thermal expectation prediction result for any occupant changes to indicate that there is a need for temperature adjustment, the above analysis can be performed on that occupant.

[0066] In step S105, the cabin air conditioner is used to supply air and adjust the temperature of the target parts where the regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target parts meets the second preset condition.

[0067] For any target location, if the thermal comfort of the area corresponding to that target location does not meet the second preset condition, the cabin air conditioning can be used to supply air and adjust the temperature of that target location until the thermal comfort of the area corresponding to that target location meets the second preset condition. The specific content of the second preset condition can be flexibly set according to actual usage needs, and this disclosure does not impose specific limitations on it.

[0068] In one example, the second preset condition may include whether the thermal comfort value of the area corresponding to any target part is within a second preset range. The specific value of the second preset range can be flexibly set according to actual usage needs; for example, the second preset range can be set to -0.5 to 0.5, etc., and this disclosure does not impose specific limitations on it.

[0069] In one example, the second preset condition may include whether the value of the regional thermal comfort corresponding to any target part is within the range of -0.5 to 0.5. If the value of the regional thermal comfort corresponding to any target part is greater than or equal to -0.5 and less than or equal to 0.5, it can be determined that the regional thermal comfort of the target part meets the second preset condition; if the value of the regional thermal comfort corresponding to any target part is less than -0.5 or greater than 0.5, it can be determined that the regional thermal comfort of the target part does not meet the second preset condition.

[0070] The following section, in conjunction with possible implementation methods of this disclosure, details the process of using in-cabin air conditioning to supply air and adjust the temperature of target areas where the regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target areas meets the second preset condition. This will not be elaborated upon here.

[0071] Through the above process, considering the individual thermal comfort needs of different occupants, air supply and temperature adjustment can be applied to the target parts of the target occupant whose regional thermal comfort does not meet the second preset condition, thereby further improving the accuracy of temperature regulation, improving the regional thermal comfort and overall thermal comfort of each target part of the target occupant, and reducing the mutual influence generated when different occupants are subjected to thermal comfort regulation separately.

[0072] In this embodiment of the disclosure, the thermal neutral temperature of the target vehicle can be determined based on the ambient temperature outside the vehicle and the solar radiation intensity inside the vehicle. Based on the thermal neutral temperature, the real-time temperature inside the vehicle is regulated by the vehicle's air conditioning system until the real-time temperature inside the vehicle meets the first preset condition. This incorporates the influence of solar radiation on the thermal environment inside the vehicle into the temperature regulation process, improving the accuracy and comprehensiveness of temperature regulation and ensuring that the real-time temperature inside the vehicle can initially meet the normal physiological metabolic needs and thermal comfort needs of each occupant. When the real-time temperature inside the cabin meets the first preset condition, the facial infrared image of the target occupant in the target vehicle can be input into the target thermal expectation prediction model to determine the thermal expectation prediction result of the target occupant, thereby indicating the temperature adjustment needs of the target occupant. If the thermal expectation prediction result indicates that there is a need for temperature adjustment, the thermal comfort of each target part is determined according to the real-time temperature of the area corresponding to each target part of the target occupant. Then, the cabin air conditioning is used to supply air and adjust the temperature of the target parts whose regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target parts meets the second preset condition. This achieves precise temperature adjustment based on body parts while considering the personalized thermal comfort needs of different occupants, effectively improving the thermal comfort of the target occupants, and reducing the mutual interference caused by individually adjusting the thermal comfort of different occupants. Furthermore, it eliminates the need for the target occupant to manually control the cabin air conditioning to adjust the temperature, reducing the probability of unreasonable cabin air conditioning settings, improving the energy utilization efficiency of the target vehicle, and reducing the operating cost of the target vehicle.

[0073] In one possible implementation, the thermal neutral temperature of the target vehicle is determined based on the ambient temperature outside the vehicle and the solar radiation intensity inside the vehicle, including: determining the thermal resistance of the group clothing corresponding to the target vehicle based on the ambient temperature outside the vehicle; and determining the thermal neutral temperature based on the thermal resistance of the group clothing and the solar radiation intensity inside the vehicle.

[0074] Clothing thermal resistance can represent the resistance to heat flow between layers of clothing due to temperature differences, and can be used to measure the insulation effect and thermal conductivity of clothing.

[0075] Based on the ambient temperature outside the cabin, the clothing of the target occupants can be easily determined, and the thermal resistance of the group clothing corresponding to the target vehicle can be estimated. Specifically, the thermal resistance of the group clothing can be expressed by formula (1):

[0076] I clo =a·T out +b (1)

[0077] Among them, I clo Indicates the thermal resistance of group clothing; T outThe external ambient temperature is represented by ; a and b represent regression coefficients, the specific values ​​of which can be flexibly set according to actual usage requirements. For example, the specific values ​​of regression coefficients a and b can be determined by statistical analysis based on experimental data under different ambient temperatures, etc. This disclosure does not impose specific limitations on this.

[0078] Based on the thermal resistance of the group's clothing and the intensity of solar radiation inside the cabin, the thermal neutral temperature can be determined, specifically expressed as formula (2):

[0079] T neuin =n·I clo +m·I sol +k (2)

[0080] Among them, T neuin Indicates the thermal neutral temperature; I sol The value of m represents the solar radiation intensity inside the cabin; m and k represent the regression coefficients, and their specific values ​​can be flexibly set according to actual usage requirements. For example, the specific values ​​of the regression coefficients m and k can be determined by statistical analysis based on experimental data under different solar radiation intensities. This disclosure does not impose specific limitations on this.

[0081] In one possible implementation, when the thermal expectation prediction result indicates a need for temperature adjustment, the regional thermal comfort corresponding to each target part is determined based on the real-time temperature of the area corresponding to each target part of the target occupant. This includes: for any target part, determining the regional thermal comfort of that target part based on the preset regression coefficient and the real-time temperature of the area corresponding to that target part.

[0082] The specific value of the preset regression coefficient corresponding to any target part can be flexibly set according to actual usage needs, depending on the actual situation of the target part. This disclosure does not impose specific limitations on this.

[0083] In one example, when the target area is the head region, the thermal comfort of the corresponding area can be expressed as formula (3):

[0084] LT Supper =α1·t au -β1 (3)

[0085] Among them, LT Supper This indicates the thermal comfort level of the area corresponding to the head; t au The value represents the real-time temperature of the area corresponding to the head region; α1 and β1 represent the preset regression coefficients corresponding to the head region. Their specific values ​​can be flexibly set according to actual usage requirements. For example, the value range of α1 can be set to 0.13~0.15, and the value range of β1 can be set to 2.5~2.7. This disclosure does not impose specific limitations on these values.

[0086] In one example, when the target area is the waist and abdomen region, the thermal comfort of the corresponding area can be expressed by formula (4):

[0087] LT middle =α2·t am -β2 (4)

[0088] Among them, LT middle This indicates the thermal comfort level of the area corresponding to the waist and abdomen; t am α2 represents the real-time temperature of the area corresponding to the waist and abdomen region; α2 and β2 represent the preset regression coefficients corresponding to the waist and abdomen region. Their specific values ​​can be flexibly set according to actual usage requirements. For example, the value range of α2 can be set to 0.10~0.13, and the value range of β2 can be set to 1.6~2.1. This disclosure does not make specific limitations on these values.

[0089] In one example, when the target area is the foot region, the thermal comfort of the corresponding area can be expressed as formula (5):

[0090] LT lower =α3·t al -β3 (5)

[0091] Among them, LT lower This indicates the thermal comfort level of the corresponding area of ​​the feet; t al The value represents the real-time temperature of the area corresponding to the foot region; α3 and β3 represent the preset regression coefficients corresponding to the foot region. Their specific values ​​can be flexibly set according to actual usage needs. For example, the value range of α3 can be set to 0.09~0.11, and the value range of β3 can be set to 2.3~2.5. This disclosure does not make specific limitations on these values.

[0092] If the predicted thermal expectations of the target passengers indicate a need for temperature adjustment, by analyzing the regional thermal comfort of each target location, it is possible to make targeted temperature adjustments for target locations whose regional thermal comfort does not meet the second preset condition, thereby improving the flexibility of temperature adjustment and realizing personalized temperature adjustment for different passengers and different locations to meet the personalized thermal comfort needs of different passengers.

[0093] In one possible implementation, the cabin air conditioning is used to adjust the air supply temperature for target areas where the regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target areas meets the second preset condition. This includes: if only one target area does not meet the second preset condition, determining the air supply temperature of the target area based on the preset regression coefficient and the real-time temperature of the area; and controlling the cabin air conditioning to adjust the air supply temperature of the target area based on the air supply temperature of the target area, until the regional thermal comfort of the target area meets the second preset condition.

[0094] Specifically, if the thermal comfort of only one target location does not meet the second preset condition, only the temperature of that target location needs to be adjusted individually. In this case, the air conditioning supply temperature corresponding to that target location can be determined based on the preset regression coefficient and the real-time temperature of the area, and the cabin air conditioning can be controlled to provide targeted airflow temperature adjustment for that target location.

[0095] The specific method for determining the air conditioning supply temperature corresponding to any target location based on the preset regression coefficient and the real-time temperature of the area can be flexibly set according to actual usage needs and depends on the actual situation of the target location. This disclosure does not impose any specific limitations on this method.

[0096] In one example, when the target area is the head region, the corresponding air conditioning supply temperature T for the head region is... set1 This can be expressed as formula (6):

[0097] T set1 =β1 / α1 (6)

[0098] In one example, when the target area is the waist and abdomen region, the corresponding air conditioning supply temperature T for the waist and abdomen region is... set2 This can be expressed as formula (7):

[0099] T set2 =β2 / α2 (7)

[0100] In one example, when the target area is the foot region, the corresponding air conditioning supply temperature T for the foot region is... set3 This can be expressed as formula (8):

[0101] T set3 =β3 / α3 (8)

[0102] If the thermal comfort of a target area does not meet the second preset condition, the thermal comfort of the target area can be adjusted by supplying air to that target area so that the thermal comfort of the target area meets the second preset condition. This confirms that the personalized thermal comfort control for the target occupant has been completed.

[0103] In one possible implementation, the cabin air conditioning system is used to adjust the temperature of target areas where the regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target areas meets the second preset condition. This includes: when multiple target areas do not meet the second preset condition, determining priority temperature-adjusted areas based on the regional thermal comfort of each target area; determining the air conditioning supply temperature of the priority temperature-adjusted areas based on the preset regression coefficient and regional thermal comfort of the priority temperature-adjusted areas; controlling the cabin air conditioning system to adjust the air supply temperature of the priority temperature-adjusted areas based on the air supply temperature of the priority temperature-adjusted areas, until the regional thermal comfort of the priority temperature-adjusted areas meets the second preset condition; and when the regional thermal comfort of the priority temperature-adjusted areas meets the second preset condition, re-determining the regional thermal comfort of each target area, and adjusting the air supply temperature of target areas where the regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target areas meets the second preset condition.

[0104] When the thermal comfort of multiple target locations does not meet the second preset condition, considering that the cabin air conditioning in the target vehicle usually cannot simultaneously supply air to multiple target locations, and that the degree of impact of the regional thermal comfort of different target locations on the overall thermal comfort of the target occupants varies, priority temperature-regulating locations can be determined based on the regional thermal comfort of each target location, and the cabin air conditioning can be controlled to supply air and regulate the temperature of the priority temperature-regulating locations. The specific method for determining the priority temperature-regulating locations based on the regional thermal comfort of each target location can be flexibly set according to actual usage needs, and this disclosure does not impose specific limitations on it.

[0105] In one example, the priority of each target part can be preset according to the personal habits of the target occupant, and then the priority temperature adjustment part can be determined among the target parts whose regional thermal comfort does not meet the second preset condition based on the priority of each target part.

[0106] Based on the preset regression coefficients and regional thermal comfort of the priority temperature control area, the air conditioning supply temperature of the priority temperature control area can be determined, and the cabin air conditioning can be controlled to supply air to the priority temperature control area until the regional thermal comfort of the priority temperature control area meets the second preset condition. The specific method for determining the air conditioning supply temperature of the priority temperature control area can refer to the aforementioned method for determining the air conditioning supply temperature of any target area, and will not be elaborated here.

[0107] During the process of adjusting the air supply temperature for priority temperature-controlled areas, the real-time temperature of other target areas will also be affected, thus changing their corresponding regional thermal comfort. Therefore, after the regional thermal comfort of the priority temperature-controlled areas meets the second preset condition, it is necessary to redetermine the regional thermal comfort of each target area, and adjust the air supply temperature for target areas whose regional thermal comfort still does not meet the second preset condition according to the aforementioned method; by repeatedly iterating the aforementioned steps until the regional thermal comfort of all target areas meets the second preset condition, the personalized thermal comfort control for the target occupant can be determined to be complete.

[0108] In one possible implementation, when the regional thermal comfort of multiple target locations does not meet the second preset condition, priority temperature-adjusting locations are determined based on the regional thermal comfort of each target location. This includes: determining the priority of each target location based on its corresponding temperature-adjusting weight and regional thermal comfort; and determining the priority temperature-adjusting locations based on the priority of each target location.

[0109] The specific value of the temperature control weight corresponding to any target part can be flexibly set according to actual usage requirements, depending on the actual situation of the target part. This disclosure does not impose specific limitations on this.

[0110] In one example, when the target area is the head region, the temperature control weight for the head region can be set to 0.34; the priority P for the head region... upper This can be expressed as formula (9):

[0111] P upper =0.34|LTS upper | (9)

[0112] In one example, when the target area is the waist and abdomen region, the temperature control weight for the waist and abdomen region can be set to 0.31; the priority P for the waist and abdomen region... middle This can be expressed as formula (10):

[0113] P middle =0.31|LTS middle | (10)

[0114] In one example, when the target area is the foot region, the temperature control weight for the foot region can be set to 0.35; the priority P for the foot region... lower This can be expressed as formula (11):

[0115] P lower =0.35|LTS lower | (11)

[0116] Through the above process, the priority of each target part can be flexibly determined according to the actual regional thermal comfort of each target part. Compared with the method of setting a fixed priority, it can further improve the personalization and applicability of cabin temperature regulation.

[0117] Figure 2 This diagram illustrates a process schematic of a method for controlling the temperature of a vehicle compartment according to an embodiment of the present disclosure. Figure 2 As shown, the target vehicle is equipped with a multimodal data monitoring system, which includes an in-cabin monitoring camera, an external temperature sensor, an in-cabin solar radiation sensor, an internal temperature sensor, an infrared thermal imaging camera, and multiple temperature sensor groups.

[0118] If the in-cabin monitoring camera detects the presence of occupants inside the target vehicle, the thermoneutral temperature of the target vehicle is determined based on the ambient temperature outside the cabin from the external temperature sensor and the solar radiation intensity inside the cabin from the internal solar radiation sensor. If the in-cabin monitoring camera detects no occupants inside the target vehicle, real-time monitoring of the cabin temperature is stopped.

[0119] Based on the thermal neutral temperature and the real-time cabin temperature from the cabin temperature sensor, it is determined whether the real-time cabin temperature meets the first preset condition. If the real-time cabin temperature meets the first preset condition, the real-time cabin temperature is continuously monitored; if the real-time cabin temperature does not meet the first preset condition, the real-time cabin temperature is adjusted until it meets the first preset condition, and then the real-time cabin temperature is continuously monitored.

[0120] While the real-time temperature inside the cabin meets the first preset condition and the real-time temperature inside the cabin is continuously monitored, the infrared facial image of the target occupant from the infrared thermal imaging camera is input into the target thermal expectation prediction model to determine the thermal expectation prediction result, and to determine whether the target occupant has a need for temperature adjustment based on the thermal expectation prediction result.

[0121] If the thermal expectation prediction result indicates that the target occupant does not require temperature adjustment, the changes in the thermal expectation prediction result are continuously monitored. If the thermal expectation prediction result indicates that the target occupant requires temperature adjustment, based on the real-time regional temperatures of multiple target locations from multiple temperature sensor groups, it is determined whether there are target locations where the regional thermal comfort does not meet the second preset condition.

[0122] If there are no target locations where the regional thermal comfort does not meet the second preset condition, continuously monitor changes in the thermal expectation prediction results. If there are target locations where the regional thermal comfort does not meet the second preset condition, adjust the air supply to those target locations until the regional thermal comfort of all target locations meets the second preset condition.

[0123] In this embodiment of the disclosure, the thermal neutral temperature of the target vehicle can be determined based on the ambient temperature outside the vehicle and the solar radiation intensity inside the vehicle. Based on the thermal neutral temperature, the real-time temperature inside the vehicle is regulated by the vehicle's air conditioning system until the real-time temperature inside the vehicle meets the first preset condition. This incorporates the influence of solar radiation on the thermal environment inside the vehicle into the temperature regulation process, improving the accuracy and comprehensiveness of temperature regulation and ensuring that the real-time temperature inside the vehicle can initially meet the normal physiological metabolic needs and thermal comfort needs of each occupant. When the real-time temperature inside the cabin meets the first preset condition, the facial infrared image of the target occupant in the target vehicle can be input into the target thermal expectation prediction model to determine the thermal expectation prediction result of the target occupant, thereby indicating the temperature adjustment needs of the target occupant. If the thermal expectation prediction result indicates that there is a need for temperature adjustment, the thermal comfort of each target part is determined according to the real-time temperature of the area corresponding to each target part of the target occupant. Then, the cabin air conditioning is used to supply air and adjust the temperature of the target parts whose regional thermal comfort does not meet the second preset condition, until the regional thermal comfort of all target parts meets the second preset condition. This achieves precise temperature adjustment based on body parts while considering the personalized thermal comfort needs of different occupants, effectively improving the thermal comfort of the target occupants, and reducing the mutual interference caused by individually adjusting the thermal comfort of different occupants. Furthermore, it eliminates the need for the target occupant to manually control the cabin air conditioning to adjust the temperature, reducing the probability of unreasonable cabin air conditioning settings, improving the energy utilization efficiency of the target vehicle, and reducing the operating cost of the target vehicle.
