Description

Technical Field

[0001] This invention relates to the field of automotive thermal management technology, and in particular to a control method, system, and vehicle for an adaptive intelligent constant temperature cabin. Background Technology

[0002] Existing constant temperature cabin control solutions collect sensor signals such as in-vehicle temperature, outside temperature, and sunlight intensity after the user leaves the vehicle, and automatically turn on the air conditioning based on preset thresholds to maintain a constant in-vehicle temperature; at the same time, they combine the user's historical travel time data to predict the next time to use the vehicle and adjust the comfort level in advance.

[0003] However, when vehicles are parked in shaded environments such as underground garages or multi-story parking garages, the sunlight intensity signal is continuously missing, and the thermostatic control function completely fails because the triggering conditions cannot be met. At the same time, the air temperature in the shaded environment of the underground garage (usually 25-30℃) is significantly lower than the actual outdoor air temperature (which can reach over 40℃ in summer). As a result, the readings of the vehicle's outside temperature sensor are significantly deviated, causing the system to make incorrect seasonal determinations, further increasing the risk of functional failure. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention provides a control method, system, and vehicle for an adaptive intelligent constant temperature cabin.

[0005] To achieve the above objectives, a first aspect of the present invention provides a control method for an adaptive intelligent climate-controlled cabin, comprising: Get the vehicle interior temperature, exterior temperature, sunlight intensity, and online weather temperature; When the sunlight intensity remains below the minimum light threshold and the deviation between the outside temperature and the network weather temperature exceeds the preset calibration deviation range, it is determined that the vehicle is in a shaded environment, and the network weather temperature is used as the external temperature reference; otherwise, the outside temperature is used as the external temperature reference. The current season type is determined based on the external temperature reference. When the user has left the vehicle and the climate control cabin function is enabled, the temperature adjustment direction is determined according to the current season type to maintain the interior temperature at the target constant temperature.

[0006] Furthermore, determining the temperature adjustment direction based on the current season type includes: cooling if it is summer, heating if it is winter, and heating or cooling if it is spring or autumn, depending on the deviation between the vehicle interior temperature and the constant temperature target temperature.

[0007] Furthermore, the determination of being in a shaded environment also distinguishes between seasons: if it is summer, the vehicle's outside temperature is lower than the network weather temperature and the deviation exceeds a preset range when it is determined to be in a shaded environment; if it is winter, the vehicle's outside temperature is higher than the network weather temperature and the deviation exceeds a preset range when it is determined to be in a shaded environment.

[0008] Furthermore, it also includes trend-based adjustment when driving out of a shaded environment: based on navigation data, the estimated distance or time to drive out to the outside is determined, and the temperature adjustment rate is linearly adjusted accordingly to make the interior temperature adapt to the outdoor ambient temperature when driving out to the outside.

[0009] Furthermore, it also includes: acquiring users' historical travel time data, grouping them by date type to establish independent prediction models, and predicting the expected travel time; sending a travel confirmation inquiry to the user before the expected travel time arrives, and adjusting the target temperature inside the vehicle from the constant temperature target temperature to the comfort target temperature when confirmation is received or no feedback is received.

[0010] Furthermore, it also includes the correction of the comfort target temperature: obtaining historical outdoor temperature and historical online weather temperature data corresponding to the expected travel time, and correcting the comfort target temperature according to their statistical patterns.

[0011] Furthermore, when adjusting the target temperature inside the vehicle to the aforementioned comfortable target temperature, the system also controls the seats according to the current season: if it is summer, the seat ventilation is turned on, and if it is winter, the seat heating is turned on.

[0012] Furthermore, the season determination is based on the following condition: the external temperature reference is not lower than a first temperature threshold. The time is determined to be summer, and the temperature is not higher than the second temperature threshold. The system is determined to be in winter if the time is right, otherwise it is determined to be in spring or autumn. The conditions under which the constant temperature cabin function is allowed to operate include the user being away from the vehicle, the function being turned on, and the battery level being higher than the threshold.

[0013] Furthermore, the first temperature threshold The following settings are adopted: based on the steady-state thermal balance equation of the carriage.

Solar irradiance, For the glass area, The overall heat transfer coefficient of the vehicle body, The heat exchange area of ​​the vehicle body. This represents the maximum irradiance on a sunny day.

[0016] Furthermore, the second temperature threshold Configure it as follows:

[0017] in, The lower limit of human comfort temperature. This is the correction value for vehicle body heat loss.

[0018] Furthermore, the in-vehicle temperature intervention threshold The following settings are adopted: based on VOC volatilization kinetic constraints, using the Arrhenius-type volatilization rate equation.

[0019] make The inverse solution yields

[0020] in, The limit for healthy VOC concentration in vehicle interiors, room temperature Lower baseline concentration; is the evaporation rate constant.

[0021] Furthermore, the constant temperature target temperature Configure it as follows:

[0022] in, To control the margin.

[0023] Furthermore, the cooling method is as follows: firstly, the external circulation ventilation is turned on, and then the cooling is turned on according to the real-time changes in the temperature and humidity inside the vehicle, so as to control the temperature to the constant temperature target temperature and the humidity below the humidity threshold; the heating method is as follows: the internal circulation heater is turned on, and the heating power is adjusted according to the changes in the temperature inside the vehicle, so as to control the temperature to the constant temperature target temperature.

[0024] A second aspect of the present invention provides a control system for an adaptive intelligent climate-controlled cabin, comprising: The sensor acquisition module is used to collect and report the vehicle interior temperature, exterior temperature, and sunlight intensity. The vehicle control system is used to provide network weather temperature, vehicle status information, and user historical travel time data; The storage and processing center is used to receive reported data and vehicle information, and generate temperature regulation control commands. The remote system is used to push information to user terminals and send user feedback instructions to the storage and processing center; An air conditioning system is used to receive the control commands and perform heating, cooling, or ventilation operations; A seat system for receiving the control commands to perform seat ventilation or seat heating operations.

[0025] Furthermore, the storage and processing hub is communicatively connected to the sensor acquisition module, the vehicle control system, the air conditioning system, the seat system, and the remote system.

[0026] Furthermore, the sensor acquisition module includes a sunlight intensity sensor, configured to continuously output a sunlight intensity signal carrying duration information to the storage and processing center; a network weather and temperature data channel is provided between the storage and processing center and the vehicle control system.

[0027] Furthermore, the vehicle control system is equipped with a calendar information output interface and a navigation data output interface. The calendar information output interface is used to output a date type identifier to the storage and processing center, and the navigation data output interface is used to output the estimated distance or estimated time for the vehicle to leave the shaded environment to the storage and processing center.

[0028] A third aspect of the present invention provides a vehicle including the adaptive intelligent climate-controlled cabin control system provided in the second aspect of the present invention.

[0029] Compared with existing technologies, the present invention provides an adaptive intelligent constant temperature cabin control method, system and vehicle. By introducing network weather temperature as a reliable reference source that is not affected by the underground parking environment in the shading scenario, and using the abnormal deviation between the outside temperature and the network weather temperature combined with the continuous lack of sunlight intensity as the dual judgment conditions for the shading parking state, the system can still accurately identify the current season type and start the constant temperature control function normally when the sunlight intensity signal is completely absent, thus realizing the maintenance of intelligent cabin constant temperature in all weather and all scenarios.

[0034] Example 1 like Figure 1 This embodiment provides a control method for an adaptive intelligent constant temperature cabin, including: S101: Obtain vehicle interior temperature, vehicle exterior temperature, sunlight intensity, and network weather temperature.

[0035] This step completes the collection and preprocessing of environmental data, including the outside temperature. Car interior temperature Humidity inside the car and sunlight intensity Perform filter preprocessing to obtain the vehicle exterior temperature. Car interior temperature Humidity inside the car and sunlight intensity This is to remove noise caused by sensor placement and surrounding environmental interference, ensuring the accuracy of data used in subsequent judgments. It carries duration information for subsequent timing determination; As an initial reference value for the outside temperature, it needs to be further compared and calibrated with the online weather temperature. Simultaneously acquire vehicle status information, including: whether the user has enabled the constant temperature cabin function, the current remaining battery power, whether the user has locked the vehicle and left, the current date type (weekday, weekend, or public holiday), and the online weather temperature.

[0036] Specifically, the filtered Compare with online weather temperatures: when the difference is within acceptable limits. Within the time frame, it is believed that Accurate and usable; readings outside this range indicate that the sensor readings are affected by local environmental interference and cannot be directly used for seasonal determination. This calibration step avoids misjudgments of the season caused by localized heat source interference or abnormal parking environments. Simultaneously, it records the user's daily travel times, filters valid travel times, and stores them categorized by date type for future travel time prediction.

[0037] S102. When the sunlight intensity is continuously lower than the minimum light threshold and the deviation between the outside temperature of the vehicle and the network weather temperature exceeds the preset calibration deviation range, it is determined that the vehicle is in a shaded environment and the network weather temperature is used as the external temperature reference; otherwise, the outside temperature of the vehicle is used as the external temperature reference.

[0038] This step completes the identification of the shaded parking status and the switching of the external temperature reference. When Continuous preset duration (For example, for 30 minutes) the light intensity remains below the minimum light threshold. ,and The deviation from the online weather temperature exceeds the preset calibration deviation range. At that time, it is determined that the vehicle is in a shaded parking state, and the sunlight intensity trigger condition is blocked, so the network weather temperature is used instead. As an external temperature reference, and based solely on the interior temperature The system uses a conversion estimate of the online weather temperature to determine whether to activate the thermostat; when the car is not parked in a shaded parking state, Exceeding the vehicle interior temperature intervention threshold and Exceeding the sunlight intensity threshold When sunlight intensity is consistently absent, the system determines that the temperature-controlled cabin function needs to be activated. The significance of this dual-judgment condition (combined judgment based on the continuous absence of sunlight and abnormal deviations in outside and online weather temperatures) lies in the following: relying solely on the absence of sunlight signals cannot distinguish between long-term parking in underground garages and scenarios such as tunnel crossings or temporary shading under overpasses; relying solely on temperature deviations may lead to misjudgments due to sensor errors or interference from local heat sources. The combined judgment effectively improves the accuracy and robustness of shading-based parking recognition, enabling the system to accurately identify the seasonal type and normally activate temperature control even when sunlight intensity signals are completely absent, filling a functional gap in existing solutions for high-frequency urban parking scenarios such as underground garages.

[0039] The thresholds mentioned above are set based on the following criteria: Minimum illumination threshold. Used to determine whether a sunlight intensity signal is substantially missing. Normal outdoor sunny day irradiance is typically between 400 and 1200 ppm. Sensor readings inside the basement are typically close to zero (<5). (Ultimate noise limit for integrated sensor measurements) (typical value) (and the upper limit of diffused light intensity of artificial lighting in the basement) (Typical value 5) ), Determine using the following formula:

[0040] when consistently below 10 At this time, it is assumed that the sunlight intensity signal is essentially missing; this value can be adjusted based on the accuracy calibration of the actual vehicle's sensors. Continuous preset duration. To distinguish between short-term and long-term shaded parking: Urban tunnel crossings typically last from tens of seconds to 5 minutes, while underground parking garages usually last for more than 30 minutes. Setting the time to 30 minutes effectively eliminates false triggers in scenarios such as tunnel crossings and brief periods of obstruction under overpasses. Preset calibration deviation range. Used for determination Is it affected by local environmental interference? Under normal outdoor parking conditions, The discrepancy between the online weather temperature and the actual temperature comes from sensor accuracy error. Local thermal radiation effects and spatial resolution error of weather data The upper limit of normal deviation is:

[0041] In shaded parking scenarios, the temperature difference between underground parking garages and the outdoors typically reaches 10-15°C, far exceeding 3°C. Considering the overall safety margin, Set as This ensures that normal parking will not trigger the system erroneously. ), reliable triggering of shading parking ( The above thresholds can all be adjusted based on actual vehicle calibration results. In-vehicle temperature intervention threshold. This is the upper limit of the vehicle interior temperature that triggers the constant temperature cabin control, which must simultaneously meet two constraints: VOC emissions not exceeding health limits and interior materials not undergoing accelerated aging. Based on the Arrhenius-type VOC volatilization rate equation, let... Solving inversely, we get:

[0042] In the formula: The recommended VOC health concentration limit is 0.6 ppm (refer to GB / T 27630—2011, total VOC limit 0.6 ppm). ); This is the baseline concentration at 25℃; Let be the evaporation rate constant. Based on typical interior material parameters. , Substitute:

[0043] Considering both interior aging constraints and user thermal perception. Recommended temperature range: 28–32℃. Default temperature is [not specified]. The actual vehicle calibration is adjusted based on the specific interior material parameters. Sunlight intensity threshold. Ultraviolet radiation exceeds approximately 200 At that time, the photo-oxidative degradation rate of interior materials accelerated significantly, and the VOC volatilization rate increased accordingly. Considering both sensor accuracy and actual vehicle calibration requirements, It can be set to 200 (The actual vehicle speed can be between 150 and 300) (Adjustments within the scope).

[0044] Furthermore, the determination of shading parking status can also incorporate seasonal deviation direction differentiation: if it is currently summer, then in Below the network weather temperature and the deviation exceeds At the time, combined consistently below The parking situation is deemed to be due to obstructed sunlight: In summer, the temperature in the underground parking garage typically remains between 25 and 30°C, while the outdoor temperature can reach over 40°C. The system will be systematically low; if it is currently winter, then... Temperatures higher than the online weather temperature and deviations exceeding [a certain value] At the time, combined consistently below The parking space was determined to be in a shaded parking condition. In winter, due to the building's insulation, the temperature inside the underground parking garage is typically higher than the outdoor temperature. The error rate may be systematically high. By distinguishing the direction of temperature deviation in different seasons, the false judgment rate can be further reduced, making the recognition of shading parking more accurate and more adaptable to different seasons.

[0045] As an alternative, in addition to the sensor signal combination judgment mentioned above, a vehicle positioning system (GPS) combined with a map database can be used to determine whether a vehicle is in an underground parking area, serving as a substitute or auxiliary means for identifying parking in shaded conditions. When the GPS location matches the underground parking area marked in the map database, it is directly determined to be in a shaded parking state, without waiting for the sunlight intensity signal to remain below a threshold for a sequential judgment process. This results in a faster response time and can reduce the response time for shaded parking recognition from... (For example, 30 minutes) This is shortened to the instant the vehicle enters the underground parking garage, effectively reducing the functional gap between the vehicle entering the shaded parking environment and the activation of the constant temperature control. GPS determination and sensor signal determination can be redundant: when the GPS signal is weak or the map data is incomplete, it reverts to the sensor signal determination method; when the sensor fails to collect data normally due to a malfunction, GPS determination can serve as a backup solution to ensure the reliability of the system in various scenarios.

[0046] S103. Determine the season based on the external temperature reference to obtain the current season type.

[0047] This step uses the external temperature reference determined in S102 (network weather temperature if the car is parked in a shaded state, otherwise...) Seasonal determination: The external temperature baseline is not lower than the first temperature threshold. The time is determined to be summer; the temperature is not higher than the second temperature threshold. It was determined to be winter ( When the temperature falls between these two values, it is determined to be spring or autumn. In shaded parking conditions, the season determination is based on network weather temperature, effectively avoiding misjudgments caused by interference from the parking garage's ambient temperature; in non-shaded parking conditions, the season determination is based on... The execution maintained the stability of the original control logic.

[0048] Specifically, Derived based on the steady-state thermal balance equation of the passenger compartment. Ignoring internal heat sources, the steady-state temperature inside the passenger compartment is... satisfy:

[0049] In the formula: The ambient temperature outside the vehicle; The solar radiation absorption coefficient of the glass; Solar irradiance ( ); For the glass area ( ); The overall heat transfer coefficient of the vehicle body ( ); For the heat exchange area of ​​the vehicle body ( ).make (That is, the interior temperature does not exceed the intervention threshold, so there is no need to start the cooling system), the inverse solution is:

[0050] in Take the maximum irradiance on a sunny day (approximately 1000). Substituting typical passenger car parameters () , , , , The correction amount is approximately 23 K. The actual vehicle calibration time can be adjusted within a certain range. Based on the lower limit of human cold comfort and referring to the ISO 7730 thermal comfort standard, when the outside temperature is lower than... When the air temperature inside the vehicle is stationary and unheated, it will be lower than the lower limit of human comfort (approximately 18°C), requiring the heating system to be activated. The winter threshold is:

[0051] In the formula The lower limit of human comfort temperature (18℃). This is the correction value for vehicle body heat loss (taken as 8K), which can be adjusted within the range when calibrating the actual vehicle.

[0052] After determining the season, it is also necessary to determine whether the climate control cabin function meets the operating conditions: the user has left the vehicle, the climate control cabin function is turned on, and the vehicle's remaining battery power is higher than the battery threshold. Furthermore, the high-voltage status of the entire vehicle must meet the requirements; subsequent constant temperature control can only be implemented when all the above conditions are met. (Electricity threshold) The setting is based on the law of conservation of energy: assuming the total battery capacity of the vehicle is... (kWh), the average power consumption of the air conditioner is (kW), the duration of constant temperature maintenance is (h), the minimum commuting range for the next day is (km), energy consumption per 100 kilometers is (kWh / 100km), then:

[0053] Substituting the parameters of a typical pure electric vehicle ( , , , , After adjusting for the actual duty cycle of the air conditioner, which is approximately 40%, It can be set to 20%. When the remaining battery power of the vehicle is below 20%, the system will pause the constant temperature cabin function and notify the user. This threshold can be adjusted according to the user's set commuting mileage requirements.

[0054] S104. When the user has left the vehicle and the constant temperature cabin function is enabled, determine the temperature adjustment direction according to the current season type and maintain the vehicle interior temperature at the constant temperature target temperature.

[0055] This step, based on the correct identification of the seasonal type in S101-S103, executes graded constant temperature control and coordinates the completion of departure trend adjustment, travel time prediction, and comfort temperature pre-adjustment. Once the operating conditions are met, temperature adjustment is executed according to the graded control logic: during summer cooling, the external circulation ventilation is activated first to exchange the hot air accumulated inside the vehicle with the outside air, and then... and The system activates the cooling system based on real-time temperature changes, maintaining the interior temperature at the target constant temperature. And control the humidity inside the car to the humidity threshold. The following steps are recommended: First, ventilate the vehicle to quickly expel hot and humid air, reducing the initial load on the cooling system and simultaneously lowering the humidity inside the car, thus reducing the promoting effect of high humidity on VOC emissions. When warming up in winter, turn on the internal circulation heater to heat the air inside the car. The heating power is adjusted in real time to control the interior temperature to [the desired level]. The internal air circulation mode prevents cold air from entering, reducing heat loss and preventing damp, cold air from entering the car in winter, which can cause fogging. In spring and autumn... and The direction of deviation determines whether to increase or decrease the temperature: if Then start cooling, if Then start heating up, if (Dead zone threshold) If the temperature is set to 1℃, the current state will be maintained to avoid energy waste caused by frequent start-stop cycles.

[0056] Constant temperature target temperature The setting is based on the VOC volatilization kinetic equation:

[0057] In the formula: For temperature VOC concentration at ( ); Reference temperature VOC concentration below; The material's evaporation rate constant ( (Typical value 0.03–0.08). This represents the increase in temperature. As the interior temperature rises, VOC concentration increases exponentially; high humidity and strong sunlight further accelerate the aging of the interior materials. Maintaining the interior temperature at [temperature range missing] is crucial. It can effectively suppress VOC emissions and reduce the aging of interior materials. The air conditioning maintains the interior temperature. Required cooling power Determined by the energy conservation equation:

[0058] To balance VOC suppression effectiveness with energy consumption, Pick The following margin is guaranteed:

[0059] in To control the margin, a value of 4–6 K is recommended. , For example, then .by Substituting this into the equation, when the vehicle interior temperature is controlled from 50℃ to 25℃, the VOC concentration decreases by approximately 71.3%. Considering both the VOC suppression effect and energy consumption balance, A humidity threshold of 25℃ is recommended for summer and 20℃ for winter, with an adaptive adjustment between 20℃ and 25℃ in spring and autumn. The setting is as follows: When the relative humidity inside the car exceeds 60%, the amount of water adsorbed by porous interior materials (such as fabrics and leather) increases significantly, and the co-adsorption effect of water molecules and VOC molecules accelerates the desorption of VOCs; when the humidity exceeds 70%, it can also cause mold growth and odor in the interior. The RH level is set at 60% to suppress VOC emissions and prevent the interior from becoming damp and moldy.

[0060] Furthermore, this invention also solves the temperature transition problem when a vehicle moves from a shaded parking environment to the outdoors. When a vehicle moves from an underground parking garage to the outdoors, the external ambient temperature changes abruptly (e.g., from 28°C in the garage to 40°C outdoors). If the constant temperature control strategy is not adjusted accordingly, the temperature inside the vehicle will rapidly deviate during the exit process. More seriously, during the system's delayed response due to historical conditions, the rapid rise in vehicle interior temperature leads to a large-scale release of VOCs, completely disrupting the system's protective function. Therefore, when the vehicle is parked in a shaded area and begins to move out, the estimated total distance is obtained from navigation data. Or estimate the total time based on the current remaining distance. Temperature regulation rate Perform linear adjustment:

[0061] In summer cooling scenarios, with Decrease The linear increase ensures that the interior temperature reaches a level compatible with the outdoor temperature by the time the vehicle is driven out, preventing a sudden temperature rise that could trigger a concentrated release of VOCs. In winter heating scenarios, [the temperature increases linearly]. Decrease The temperature rise rate is gradually reduced linearly to avoid excessive temperature differences between the inside and outside of the vehicle after exiting the parking garage, which could affect passenger comfort. This trend-based adjustment achieves a smooth temperature transition during the exit process from a shaded parking space, eliminating the abrupt temperature change when switching from a shaded environment to an outdoor environment. This significantly improves the cabin comfort experience for users as they exit the parking garage. At the same time, by adjusting the temperature regulation rate in advance, the system completes adaptive pre-adjustment to the outdoor ambient temperature before the vehicle leaves, effectively preventing the concentrated release of VOCs due to rapid temperature rise at the moment of exiting the parking garage, and achieving a seamless transition of the constant temperature function protection window.

[0062] As an alternative, in addition to a linear rate adjustment scheme based on navigation-estimated distance / time, a real-time speed-based scheme can also be used. and current distance from the exit Dynamic speed adjustment scheme: dynamically calculate the estimated departure time Updated in real time based on this. This enables more precise temperature transition control. Even in scenarios where navigation data is unavailable or map data is incomplete, this solution can still achieve trend-based adjustments based on real-time vehicle speed and distance information, serving as a redundant alternative to navigation data solutions and exhibiting stronger scenario adaptability.

[0063] Furthermore, this invention also solves the problems of false triggering of travel time predictions and insufficient accuracy of comfort pre-adjustment. Existing solutions do not differentiate between date types when statistically fitting user travel times. There is a systematic difference between weekday travel times (e.g., 8:00 AM for work) and weekend / holiday travel times (e.g., 10:30 AM for leisure travel), often exceeding 2 hours. Without distinguishing date types, the system might trigger pre-adjustment at 8:00 AM on a weekend, while the user actually leaves at 10:30 AM. This results in an ineffective cycle of adjusting the car's interior temperature to comfort, no one maintaining it, it dropping, and then readjusting, leading to continuous energy waste. More seriously, users frequently receive false notifications and disable the automatic climate control function, causing the entire function to malfunction. Therefore, this invention categorizes historical travel time data by weekday ( ),weekend( ), statutory holidays ( The data is divided into three groups, and independent fitting sub-models are built for each group. During prediction, the sub-model matching the current date type is prioritized; each sub-model undergoes independent rolling calibration to prevent cross-contamination of data from different date types; if data accumulation for a certain type is insufficient (sample count below a threshold), the sub-model will be calibrated accordingly. (It can be set to 10 lines), using the fitting results of the full historical data as a backup, and switching to a dedicated sub-model after sufficient data is available, to achieve a smooth transition from cold start backup to accurate prediction. By establishing independent prediction models layered by date type, the accuracy of travel time prediction in non-working day scenarios is significantly improved, reducing false triggering of pre-temperature adjustment due to differences in date type, reducing ineffective energy consumption, and avoiding the risk of users disabling the function due to frequent false push notifications.

[0064] Specifically, after obtaining the expected travel time, further historical outdoor temperature data corresponding to that travel time period is acquired to determine the target comfort temperature. Dynamic corrections are performed. The baseline value is determined according to ASHRAE 55 standard: Summer ,winter , spring and autumn The corrected formula is:

[0065] In the formula: The average outdoor temperature (°C) for the same historical period. Reference temperature; To correct for the temperature difference, a value of 0.3 is recommended, which means the temperature difference between the inside and outside of the car will be reduced by approximately 30%. (Based on a summer afternoon...) For example, The temperature difference between the inside and outside of the car has been reduced to 6°C; during the winter morning rush hour... hour, Considering the lower limit constraint of human comfort, we take... . By recording users' historical manual temperature adjustment behavior, and then adaptively updating the temperature using the least squares method, the system can fit the data. This correction mechanism ensures that the target comfort temperature is no longer a fixed value, but is dynamically calibrated based on the historical ambient temperature patterns during the user's travel period, making the transition between the temperature felt by the user when getting into the vehicle and the outdoor ambient temperature more natural and comfortable.

[0066] Plan ahead of time prediction Within minutes, a travel confirmation message will be pushed to the user; if a confirmation is received or If no feedback is received within minutes, a comfort temperature adjustment command is sent to the air conditioning and seats to adjust the interior temperature from [previous setting]. Quickly adjust to And maintain. The setting is based on the in-vehicle heat capacity equation, and the air conditioner will change the in-vehicle temperature from... Adjust to Time required for:

[0067] In the formula: The air quality inside the vehicle (kg); The specific heat capacity of air at constant pressure; This refers to the effective cooling / heating power (W) of the air conditioner. Interior heat storage (equivalent heat capacity approximately 5–10 times that of air heat capacity) and user response time (3–5 minutes) are taken into account. The timeout can be set to 30 minutes, with a 20-minute feedback waiting time. It also controls the seats according to the current season: activating seat ventilation in summer and seat heating in winter; the intensity level varies depending on the season. Dynamically determined: Three gears are activated at any time. The second gear is activated at that time. A file is activated at any time. The system automatically shuts off or switches to a hold mode to avoid energy waste caused by overheating or over-ventilation. The coordinated operation of the seat system and the air conditioning system accelerates the rate of temperature adjustment inside the vehicle, ensuring a comfortable cabin environment for users as soon as they get in, providing a comfortable user experience from the moment they enter the vehicle.

[0068] The aforementioned travel time prediction and comfort temperature pre-adjustment are deeply technically linked to the identification of shading parking status and dynamic switching of external temperature benchmarks: accurate seasonal type determination is the key to achieving the target comfort temperature. Required input for dynamic correction: If the season determination is incorrect (e.g., misclassifying summer high temperatures as spring or autumn), then the input should be based on the season type. The reference value will introduce a systematic deviation, leading to errors in the direction or magnitude of the pre-temperature adjustment; conversely, Historical temperature corrections for shaded parking scenarios should be based on online weather temperatures, not the temperature affected by the underground parking garage. This is precisely the capability provided by the external temperature reference switching, serving as a reference benchmark. The combination of the two not only solves the problem of activating the constant temperature function in the dark parking scenario, but also ensures the accuracy of triggering the pre-temperature adjustment before travel and the precision of the temperature setting. This enables the entire constant temperature cabin function to achieve closed-loop control from maintaining a constant temperature to pre-trip comfort adjustment in the high-frequency urban scenario of dark parking.

[0069] Furthermore, the operating status of the temperature-controlled cabin after the user leaves the vehicle, as well as the predicted in-vehicle environment during the trip, are pushed to the user's mobile device in real time. The user can remotely intervene at any time to adjust the operating status of the air conditioner or seats.

[0070] As an alternative, in addition to the three categories of weekdays / weekends / public holidays, it can be further subdivided into subcategories such as "weekday morning shift", "weekday evening shift", "first day of holiday", and "last day of holiday" to adapt to scenarios with more complex travel patterns; users can also actively mark their travel type on their mobile phones to help improve the accuracy of predictions.

[0071] Example 2 like Figure 2 This embodiment provides a control system for an adaptive intelligent constant temperature cabin, including a 201 sensor acquisition module, a 202 vehicle control system, a 203 storage and processing hub, a 204 remote system, a 205 air conditioning system, and a 206 seat system. Each module is centered around the 203 storage and processing hub, and operates according to... Figure 2 The connections shown enable data interaction and control command transmission. The following section will combine... Figure 2 Each module and its connection relationship are explained in detail.

[0072] The 201 sensor acquisition module is used to collect and report the vehicle interior temperature, exterior temperature, and sunlight intensity.

[0073] The sensor acquisition module is a multi-channel sensor integration module of this system, such as... Figure 2 As shown, this module specifically includes four sensing units: an interior temperature sensor, an exterior temperature sensor, a speed sensor, and a sunlight sensor. Each sensing unit collects the exterior temperature data in real time. Car interior temperature Humidity inside the car Vehicle speed signal and sunlight intensity The collected information is then reported to the storage and processing center for preprocessing. The real-time vehicle speed signal collected by the vehicle speed sensor is used for dynamic calculation of the estimated departure time and judgment of driving status during the trip prediction phase, serving as the fundamental input for the dynamic rate adjustment scheme in trend-based regulation.

[0074] The functional division of each sensing unit is as follows: The in-vehicle temperature sensor collects the temperature inside the cabin. After being filtered by the 203 storage processing center, the result is obtained. This is used to determine the current thermal environment inside the vehicle and to trigger and maintain the constant temperature control. The external temperature sensor collects the ambient temperature outside the vehicle. After filtering, the result is obtained This is used to compare the deviation with online weather temperature data, supporting the dual-judgment logic for shaded environments. The humidity sensor collects the relative humidity inside the vehicle. Used for humidity control during the summer cooling phase to ensure that the humidity inside the vehicle is maintained at the humidity threshold. The following measures are taken to prevent high humidity environments from accelerating VOC volatilization and causing mold growth in the interior. A sunlight sensor collects the solar irradiance outside the vehicle. Its output signal not only contains the current solar irradiance value, but also carries information on the continuous cumulative duration of the irradiance state, enabling the 203 storage processing center to distinguish between two scenarios: short-term shading (such as tunnel crossing) and long-term shading parking (such as underground parking). This is the hardware basis for realizing the timing judgment condition that the sunlight intensity is continuously lower than the minimum light threshold.

[0075] The aforementioned sensor data is collected by the 201 sensor acquisition module and then transmitted to the 203 storage and processing center via a one-way acquisition signal reporting link. This link is from 201 to 203 and is only responsible for data reporting; it does not carry reverse control commands.

[0076] The 202 vehicle control system is used to provide network weather temperature, vehicle status information, and user historical travel time data.

[0077] The vehicle control system is the central hub of this system, responsible for managing vehicle information and user settings related to the climate-controlled cabin function. Specifically, this includes: the status of function switches set by the user on the host, the current remaining battery power of the vehicle, whether the user has locked the vehicle and left (determined by a combination of door lock status and occupant detection signals), the specific time of the user's first use of the vehicle each day (recorded by the timestamp of the vehicle transitioning from parked to driving status), the date type corresponding to the current date (weekday, weekend, or public holiday), and the power-on or power-off status of the vehicle's high-voltage system.

[0078] like Figure 2As shown, the 202 vehicle control system and the 203 storage and processing hub engage in bidirectional communication for status requests and feedback: the 203 storage and processing hub actively initiates data requests, and the 202 vehicle control system responds with corresponding vehicle status information and user settings. Simultaneously, the 202 vehicle control system also proactively reports the user's historical travel time data to the 203 storage and processing hub to support travel time prediction. Specifically, a network weather and temperature data channel is established between the 202 vehicle control system and the 203 storage and processing hub. In shady scenarios, this provides the 203 storage and processing hub with an external temperature reference source that replaces the vehicle's external temperature sensor. This is a crucial data link for shady environment recognition and external temperature reference switching functions. The 202 vehicle control system is also equipped with a calendar information output interface and a navigation data output interface: the calendar information output interface outputs the current date type identifier (weekday, weekend, or public holiday) to the 203 storage and processing hub, supporting travel prediction based on date type hierarchical modeling; the navigation data output interface provides the 203 storage and processing hub with the estimated distance or estimated time for the vehicle to exit the shady environment, supporting trend-based adjustment for exiting the shady environment.

[0079] 203 Storage and processing hub is used to receive reported data and vehicle information, and generate temperature regulation control commands.

[0080] The storage processing hub is the core decision-making unit and data storage center of this system. Figure 2 The star-shaped topology shown serves as the central node, establishing communication connections with modules 201, 202, 204, 205, and 206 respectively. It filters and monitors in real time the in-vehicle temperature, outside temperature, in-vehicle humidity, and sunlight intensity. It executes core control logic such as identifying the shading parking status and switching the external temperature reference, determining the season, judging constant temperature control conditions, predicting travel time, and pre-adjusting the comfort temperature. Control commands are then sent to the air conditioning and seat systems, and the current status of each system is pushed to the user's mobile device via a remote system.

[0081] Specifically, the communication relationships between the 203 storage processing center and each module are as follows: With the 201 sensor acquisition module, it is a one-way signal reporting relationship: 201 actively reports, and 203 passively receives; With the 202 vehicle control system, there is bidirectional communication for status requests and feedback: 203 actively requests, and 202 responds; With the 204 remote system, there is bidirectional communication for control command issuance and status feedback: 203 pushes status information to 204, and 204 issues user commands to 203; With the 205 air conditioning system, there is bidirectional communication for executing control commands and setting feedback: 203 issues control commands such as temperature and mode, and 205 provides feedback on the current operating status and actual air outlet temperature; With the 206 seat system, there is bidirectional communication for executing control commands and status feedback: 203 issues ventilation or heating level commands, and 206 provides feedback on the current seat surface temperature and operating status.

[0082] The core logic of the 203 storage processing center is as follows: when the sunlight intensity signal remains below the minimum light threshold for a continuous preset duration, and the deviation between the outside temperature and the network weather temperature exceeds the normal calibration range, it is determined that the environment is shaded, and the network weather temperature is used as the external temperature reference; otherwise, the outside temperature is used as the external temperature reference. Then, based on the external temperature reference, a seasonal determination is made to determine the control direction of the 205 air conditioning system and the 206 seat system. Simultaneously, the 203 storage processing center establishes independent travel time prediction models grouped into three categories: weekdays, weekends, and statutory holidays. These models are continuously calibrated and predicted to predict user travel times, triggering pre-adjustment of the comfort temperature in advance.

[0083] The 204 remote system is used to push information to user terminals and send user feedback instructions to the 203 storage and processing hub.

[0084] The remote system is the mobile terminal interaction module of this system, such as... Figure 2 As shown, its specific functions include three aspects: in-vehicle temperature display, air conditioning status reminder, and user command issuance. The remote system establishes a two-way data connection with the user's mobile app through the in-vehicle T-Box, and pushes the in-vehicle environmental status (current temperature, humidity) and air conditioning operation status (cooling, heating, ventilation mode, target temperature) fed back by the 203 storage and processing center to the user's mobile device in real time in the form of "in-vehicle temperature display" and "air conditioning status reminder". The "user command issuance" operation triggered by the user through the mobile app, including confirming the trip, canceling the trip, adjusting the target temperature, and turning off the function, is received by the remote system and forwarded to the 203 storage and processing center for execution.

[0085] A certain amount of time before the predicted travel time, the 204 remote system pushes a message to the user, informing them that the vehicle interior will be adjusted to a comfortable state in advance. Upon receiving user confirmation or after waiting for the set time without feedback, the system automatically enters the comfort pre-adjustment phase. The 204 remote system and the 203 storage and processing center communicate bidirectionally: 203 pushes status information to 204, and 204 issues user commands to 203.

[0086] 205 Air conditioning system, used to receive the control commands to perform heating, cooling or ventilation operations.

[0087] The air conditioning system is the device in this system that regulates the temperature and humidity inside the vehicle, such as... Figure 2 As shown, its internal structure includes four sub-functional units: circulation control, air volume control, air outlet mode control, and air outlet temperature control. The air conditioning system receives air conditioning on / off commands and target constant temperature commands from the 203 storage and processing center. and comfortable target temperature It enters automatic operation mode and achieves precise control of the temperature and humidity inside the vehicle through the coordinated adjustment of the above four sub-functional units.

[0088] During the constant temperature maintenance phase: The circulation control unit selects either external circulation (early summer cooling) or internal circulation (winter heating and summer cooling stabilization) mode based on the current season; the airflow control unit automatically adjusts the blower speed based on the deviation between the interior temperature and the target temperature, rapidly adjusting with high airflow when the deviation is large and maintaining low airflow when the deviation is small; the air outlet mode control unit prioritizes face blowing mode in summer (using the convection effect of descending cold air to quickly reduce the perceived temperature) and foot blowing mode in winter (using the convection effect of rising hot air to quickly warm the whole body); the air outlet temperature control unit adjusts the temperature of the evaporator or heater core in real time based on the deviation between the target temperature and the actual temperature. During summer cooling, the circulation control unit prioritizes activating external circulation ventilation to replace the air inside the vehicle, and then activates cooling based on real-time changes in interior temperature and humidity to stabilize the interior temperature. Humidity control at The following applies: During winter warm-up, the circulation control unit activates the internal circulation heater, adjusting the heating power in real time according to the interior temperature to maintain the temperature at a comfortable level. During the comfort pre-temperature adjustment phase, upon receiving a command, the interior temperature will be adjusted from... Quickly adjust to It maintains and transmits the current operating status (including actual air outlet temperature, current air volume level, operating mode, etc.) back to the 203 storage processing center in real time in the form of setting feedback.

[0089] The communication between the 205 air conditioning system and the 203 storage and processing center is bidirectional: 203 sends execution control commands to 205 (including circulation mode commands, air volume commands, air outlet mode commands, and air outlet temperature commands), and 205 sends setting feedback back to 203 (including current operating mode, actual air outlet temperature, fault status, etc.).

[0090] 206 Seat system, used to receive the control commands to perform seat ventilation or seat heating operations.

[0091] The seating system is an auxiliary device in this system for adjusting seating comfort, such as... Figure 2 As shown, it specifically includes two sub-functional units: seat ventilation control and seat heating control, which correspond to the seat linkage control needs in summer and winter, respectively.

[0092] When the 203 storage and processing center issues a comfort temperature adjustment command, it automatically runs the corresponding function according to the current season. The seat ventilation control unit is activated in summer and the seat heating control unit is activated in winter to help the vehicle quickly reach a comfortable state and feed back the operating status to the 203 storage and processing center.

[0093] The seat-linked control strategy is as follows: in summer, seat ventilation is activated via the seat ventilation control unit, and in winter, seat heating is activated via the seat heating control unit; the ventilation or heating level is dynamically determined based on the difference between the interior temperature and the target comfort temperature, with a higher level indicating a larger difference; when the interior temperature reaches... It will then automatically shut off or switch to the holding position to avoid energy waste caused by overheating or ventilation. The 206 seat system and the 203 storage and processing center communicate bidirectionally: 203 sends execution control commands (ventilation level command or heating level command) to 206, and 206 sends status feedback back to 203 (current ventilation or heating level, seat surface temperature, etc.).

[0094] The seating system works in conjunction with the air conditioning system to significantly improve the rate of temperature regulation inside the vehicle, ensuring that users can enjoy a comfortable cabin environment as soon as they get in the car.

[0095] Example 3 Embodiment 3 of the present invention provides a vehicle including the adaptive intelligent constant temperature cabin control system described in Embodiment 2.

[0096] The integration of this control system at the vehicle level is as follows: The 203 storage and processing hub establishes communication connections with the vehicle's thermal management controller, battery management system, body controller, and other electronic control units via CAN bus or vehicle Ethernet, enabling direct control of components such as the air conditioning compressor, PTC heater, blower, and damper actuator. The sensors in the 201 sensor acquisition module are located in their respective positions within the vehicle: the interior temperature and humidity sensors are installed below the dashboard at the air conditioning return vents; the exterior temperature sensor is installed inside the front bumper; the sunlight sensor is installed on the dashboard near the windshield; and the speed sensor shares a data source with the vehicle's wheel speed signal or GPS signal. Each sensor reports its collected data to the 203 storage and processing hub via hard-wired signals or a LIN bus. The 202 vehicle control system provides vehicle status information to the 203 storage and processing hub via the vehicle communication network. The 204 remote system establishes data connections with the cloud server and user's mobile app via the vehicle's T-Box. The 205 air conditioning system and the 206 seat system receive control commands from the 203 storage and processing hub via the CAN bus and transmit their operating status back.

[0097] This vehicle is suitable for various powertrains, including pure electric vehicles, plug-in hybrid electric vehicles, and traditional gasoline vehicles. For pure electric vehicles and plug-in hybrid electric vehicles, the climate-controlled cabin function is directly powered by the battery, and the setting of the charge threshold a% needs to take into account both the total battery capacity and the user's commuting needs. For traditional gasoline vehicles, the climate-controlled cabin function is supported by a 12V battery and an engine-driven air conditioning compressor, and the setting of the charge threshold a% mainly considers the battery capacity and the minimum voltage requirement of the starter motor. In this case, a% can be adjusted to 40% to prioritize the reliability of vehicle starting.

[0098] After the vehicle is equipped with the aforementioned control system, it has the following operational capabilities: When the user parks the vehicle in a shaded environment such as an underground garage and locks the vehicle before leaving, the system automatically identifies the shaded environment and switches the external temperature reference to the online weather temperature, and automatically maintains the interior temperature at the constant target temperature according to the steps described in S101 to S104. Nearby, it effectively suppresses VOC emissions and material aging in the interior; simultaneously, by analyzing users' historical travel time data, it predicts users' expected travel time by weekday, weekend, and statutory holiday, and sends a notification to the user's mobile phone via a 204 remote system before the trip; after the user confirms or defaults to agree, the system automatically adjusts the interior temperature from the target constant temperature. Adjust to the target comfortable temperature It can control seat ventilation or heating in conjunction with the vehicle, and smoothly transition to the outdoor temperature environment through trend adjustment when the vehicle leaves the underground parking garage, so as to achieve a comfortable cabin experience for users from getting into the car in the underground parking garage to driving outdoors.

[0099] Specific application scenario example: On a summer weekday morning, a user parks their vehicle in the underground parking garage of an office building. The temperature inside the garage is 28°C, the outdoor temperature is 38°C, and the sunlight intensity is close to zero. The system identifies the shading environment within 30 minutes of the user locking their car: sunlight intensity... consistently below and The deviation between the online weather temperature (38℃) and the actual temperature (28℃) exceeds ±5℃: Using the online weather temperature of 38℃ as the external temperature benchmark, it is determined that it is currently summer, and the vehicle interior temperature is controlled at the constant target temperature. The system also records the user's daily car retrieval behavior pattern around 8:30 AM, and models this pattern according to weekday type. The following morning at 8:00 AM, the 204 remote system pushes a travel confirmation message to the user's mobile phone; after confirmation, the system adjusts the car's interior temperature from 25°C to the target comfortable temperature. The system automatically activates the seat ventilation. When the user arrives at the garage at 8:30 AM, the cabin is already at a comfortable 26°C. As the vehicle leaves the garage and enters the outdoors, the air conditioning temperature adjusts linearly from [previous temperature setting]. Upgraded to When the vehicle exits, the interior temperature has reached 29°C, reducing the temperature difference with the outdoor temperature of 38°C to 9°C. This avoids the concentrated release of VOCs and physical discomfort caused by the sudden temperature rise when exiting the vehicle, achieving seamless and comfortable temperature management throughout the entire process from the underground parking garage to the outdoors.

Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
