Technical Field

[0001] This application relates to the field of vehicle management technology, and in particular to a method, device, equipment, system and vehicle for controlling the environment of the passenger compartment. Background Technology

[0002] Passenger cabin ventilation systems are widely used in various vehicles, including passenger cars, commercial vehicles, and buses, covering all scenarios such as urban commuting, long-distance travel, extreme weather environments, and complex road conditions. With the popularization of new energy vehicles, the regulation of passenger cabin health and comfort by passenger cabin ventilation systems has become a core requirement.

[0003] In related technologies, passenger cabin ventilation systems often employ a tiered filtration system. This system filters air through multiple air ducts, switching dampers, and basic filters. It detects external particulate matter concentration and directly introduces outside air when the concentration indicates good air quality, activating multiple filters when the concentration indicates heavy pollution. However, this method cannot effectively detect environmental changes and struggles to maintain a stable and comfortable passenger cabin environment under complex environmental conditions. Summary of the Invention

[0049] Figure 5 This is a schematic diagram of the structure of the crew cabin environment control device provided in the embodiments of this application.

[0050] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0052] Vehicle passenger compartment environmental control technology is applied to passenger cars, commercial vehicles, and buses, targeting cabin ventilation and air handling under complex climatic conditions such as daily commuting, long-distance driving, tunnel sections, congested road sections, and high temperatures, extreme cold, rain, high humidity, and dust storms. The relevant control system typically consists of an onboard fresh air system, an air circulation system, a filtration and purification system, and actuators related to air conditioning and defogging.

[0053] In related technologies, vehicle ventilation systems typically switch between internal and external air circulation based on air quality information inside and outside the vehicle, and work with airflow adjustment and filtration to complete cabin air exchange. Some solutions add in-vehicle carbon dioxide or external particulate matter detection to trigger ventilation when air pollution is present or when there are many occupants. Some solutions control air supply through fixed-level fan speeds and damper opening and closing logic. This approach can complete basic ventilation under normal operating conditions, but it lacks sufficient sensitivity to changes in temperature, humidity, rainfall, dust storms, and regional weather patterns, making it difficult to accurately identify cabin environmental requirements under extreme weather conditions and complex road conditions. The proportion of fresh air, airflow, and purification intensity are mostly configured in stages or are fixed, which can easily amplify the air conditioning load after introducing outside air, leading to uneven cabin heating, fogging of windows, and inadequate blocking of polluted air.

[0054] Meanwhile, when vehicles are in congested, tunnel, or in bad weather, traditional systems lack coordinated control with air conditioning, defogging, and other devices. The environmental regulation actions are disconnected from each other, making it difficult to balance air quality, comfort, and energy consumption. The range performance of new energy vehicles is also easily affected.

[0055] The passenger cabin environment control method provided in this application no longer limits passenger cabin environment control to a single air parameter trigger. Instead, it combines regional meteorological information with local vehicle environmental information and incorporates vehicle operating status into the judgment criteria. This first identifies the environmental and driving scenarios in which the vehicle is located, and then calls the corresponding adjustment strategy according to the scenario. After the scenario determination is completed, control content is synchronously output to the vehicle's fresh air system and linkage system, so that the fresh air adjustment parameters and linkage parameters jointly participate in passenger cabin environment control. Based on this, placing environmental perception, scenario matching, and system linkage into the same control link helps to address the problems of adjustment lag, insufficient coordination, and high energy consumption under complex climates and variable operating conditions, making passenger cabin environment control more closely aligned with actual driving conditions.

[0056] Figure 1 This is a schematic diagram of a scenario for the crew cabin environment control method provided in the embodiments of this application, such as... Figure 1 As shown, the specific application scenario of this application embodiment includes vehicle 11, occupants 12, and processing center 13, wherein:

[0057] The processing center 13 can process multi-source environmental data and vehicle operating condition data, and generate a comprehensive control strategy based on the multi-source environmental data and vehicle operating condition data. Then, based on the comprehensive control strategy, the passenger cabin environment of vehicle 11 is adjusted to improve the comfort of passenger 12.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0059] Figure 2 This is a schematic flowchart illustrating a method for controlling the passenger cabin environment according to an embodiment of this application. Figure 2 As shown, the method includes:

[0060] S201. Acquire multi-source environmental data and vehicle operating condition data, wherein the multi-source environmental data includes at least meteorological environmental data of the area where the vehicle is located and local environmental data collected by the vehicle itself.

[0061] Multi-source environmental data is a dataset used to characterize the environmental state of the vehicle. It serves as the input basis for scene determination and control strategy generation. Meteorological environmental data characterizes the macroclimate conditions of the area where the vehicle is located. Local environmental data reflects the real-time environmental state near and inside the passenger compartment. Operating condition data characterizes the vehicle's operating status.

[0062] Specifically, the acquired multi-source environmental data and operating condition data are preprocessed to generate a current environment dataset for scene matching. Optionally, the preprocessing includes at least filtering, denoising, and calibration. For example, the acquired multi-source environmental data and operating condition data are filtered, denoised, and calibrated to obtain preprocessed multi-source environmental data and operating condition data.

[0063] By placing regional weather trends, the real-time environment around the vehicle, and the vehicle's operating status into the same input link, it is possible to grasp macro-level weather changes and micro-level cabin conditions, thus enabling environmental and driving scene recognition to be independent of a single sensor trigger.

[0064] S202. Based on multi-source environmental data and operating condition data, the environmental scenario and driving scenario of the vehicle are determined through preset scenario matching rules.

[0065] Scene matching rules are used to map multi-source environmental data and operating condition data to specific scenes. Environmental scenes describe the state of the environment surrounding the vehicle, while driving scenes describe the vehicle's driving state and road conditions.

[0066] Specifically, a fusion judgment is performed on multi-source environmental data and operating condition data.

[0067] For example, environmental scenarios and driving scenarios are determined based on meteorological environmental data, local environmental data, and operating condition data, and combined labels for environmental scenarios and driving scenarios are formed.

[0068] Optionally, the environmental scenarios include at least one of the following: normal sunny, hot and humid, cold and frigid, cloudy and humid, smog pollution, sandstorm, rain, snow and ice.

[0069] Optionally, the driving scenario includes at least one of the detailed sub-scenarios such as idling, driving, congestion, and tunnel.

[0070] By cross-judging regional meteorological environmental data, local perception results, and vehicle operating conditions, a scene recognition process for complex weather and road conditions is constructed, so that subsequent control no longer relies on a single environmental parameter, but is classified and processed according to the real environment in which the vehicle is currently located.

[0071] S203. Based on the environmental and driving scenarios, retrieve the corresponding preset environmental adjustment strategies and generate a comprehensive control strategy for adjusting the passenger cabin environment. The comprehensive control strategy includes the adjustment parameters of the vehicle's fresh air system and the linkage parameters of the linkage system.

[0072] The environmental adjustment preset strategies are a set of pre-configured adjustment schemes for different combinations of environmental and driving scenarios. These preset strategies can be retrieved via scene tag indexes.

[0073] The integrated control strategy transforms the control content in the preset environmental regulation strategy into a set of executable instructions for the current moment. Specifically, the adjustment parameters of the vehicle-mounted fresh air system are used to control the system to perform corresponding air conditioning actions. The linkage parameters of the interconnected systems are used to drive related systems to work together.

[0074] Specifically, after obtaining the combination of environmental scene and driving scene, the corresponding environmental adjustment preset strategies are retrieved.

[0075] Optionally, after obtaining the preset environmental control strategy, the data in the preset environmental control strategy can be modified by combining multi-source environmental data to form the current comprehensive control strategy.

[0076] For example, if the linkage system includes an air conditioning system, and the linkage parameters in the air conditioning system include the air conditioning temperature, and the air conditioning temperature in the preset environmental control strategy is 2 degrees Celsius higher than the outside temperature of the vehicle, then the outside temperature of the vehicle is obtained based on multi-source environmental data, and the air conditioning temperature in the integrated control strategy is determined based on the outside temperature of the vehicle.

[0077] Optionally, when the environmental or driving scenarios change, the integrated control strategy can be adjusted accordingly to adapt to the current passenger cabin environment adjustment needs.

[0078] By mapping both environmental and driving scenarios to a unified strategy, and integrating the adjustment parameters of the in-vehicle fresh air system with the linkage parameters of the other systems into a single control mechanism, the passenger cabin environment adjustment is transformed from decentralized actions into integrated decision-making. It should be understood that the above example is merely illustrative and not limiting.

[0079] Optionally, the linkage system includes at least one of the following systems: air conditioning system, defogging system, seat heating system, vehicle control system, etc.

[0080] S204. Output the integrated control strategy to the corresponding vehicle-mounted fresh air system and linkage system to control the vehicle-mounted fresh air system and linkage system to perform passenger cabin environment adjustment operations.

[0081] The vehicle's fresh air system is used to introduce, circulate, and purify air into the passenger compartment. The linkage system works in conjunction with the vehicle's fresh air system to complete related controls, while the passenger compartment environmental adjustment operation is the process of implementing the comprehensive control strategy into actual actions.

[0082] Specifically, the integrated control strategy is sent to the vehicle's fresh air system and linkage system respectively, so that the corresponding systems can perform the passenger cabin environment adjustment operation according to the integrated control strategy.

[0083] By unifying the output of the integrated control strategy, the vehicle's fresh air system and linkage system work together to dynamically adjust the passenger cabin environment based on the same control objective, and the scene recognition results are directly converted into multi-system collaborative behavior.

[0084] This application provides a method for controlling the passenger cabin environment. It incorporates regional meteorological data, local vehicle environmental information, and vehicle operating condition data into a unified sensing input, and uses scene matching rules to jointly determine the environmental and driving scenarios. Subsequently, a unified strategy generates a comprehensive control strategy that simultaneously applies to the vehicle's ventilation system and the linkage system, ensuring continuous adjustment of the passenger cabin environment based on the current actual driving conditions. Based on this control chain, the vehicle no longer relies on a single air parameter to trigger adjustments; instead, it coordinates the control of the vehicle's ventilation system and linkage system according to scenario combinations. This allows cabin environment adjustments to be executed simultaneously, reducing response lag caused by fragmented adjustment actions.

[0085] Figure 3 This is a flowchart illustrating step S204 of the passenger cabin environment control method provided in an embodiment of this application. Figure 3 As shown, in this embodiment... Figure 2 Based on the embodiments, the method for controlling the crew cabin environment is described in detail, which includes:

[0086] In one possible implementation, during the operation of adjusting the crew cabin environment, the crew cabin environment control method further includes:

[0087] S2041. Continuously collect cabin environmental data within the crew cabin.

[0088] Optionally, continuous data collection can be performed using any of the following sampling methods: continuous polling sampling or sampling at fixed intervals.

[0089] Optionally, if the continuous sampling method is sampling at a fixed period, the fixed period can be set to any value that adapts to environmental fluctuations under different vehicle speeds and climate changes. For example, the fixed period can be set to any value between 0.5 seconds and 10 seconds.

[0090] Optionally, after each collection of cabin environmental data, the cabin environmental data can be filtered and its validity verified to remove instantaneous peak values.

[0091] S2042. If the cabin environment data deviates from the comfort range corresponding to the integrated control strategy, a correction mechanism is triggered to dynamically adjust the integrated control strategy.

[0092] When cabin environmental data indicates that the occupant cabin deviates from the comfort range corresponding to the integrated control strategy, the correction mechanism partially modifies or regenerates the original integrated control strategy to keep the air conditioning, defogging, and fresh air control synchronized. Optionally, the specific manifestations of the cabin environmental data indicating that the occupant cabin deviates from the comfort range corresponding to the integrated control strategy can be at least one of the following: higher temperature, increased humidity, increased fogging, or decreased air quality.

[0093] Optionally, the controller that performs the correction mechanism can be a vehicle domain controller or an air conditioning controller. The controller stores a comfort zone parameter table and a correction rule table. In practical applications, other models of the controller can also be selected, and this application does not limit this.

[0094] By continuously collecting cabin environment data and triggering a correction mechanism in a timely manner when deviating from the comfort range, the comprehensive control strategy can be updated in a closed loop based on the real-time status of the vehicle. This ensures that the fresh air adjustment and linkage control always match the current changes in the cabin environment, thereby improving the continuity and stability of environmental adjustment and reducing control lag caused by the continuous expansion of environmental deviation.

[0095] In one possible implementation, the trigger correction mechanism dynamically adjusts the integrated control strategy, including: obtaining an environmental offset by determining the deviation between the cabin environment data and the comfort zone corresponding to the integrated control strategy; updating the adjustment parameters of the vehicle-mounted fresh air system within the integrated control strategy based on the environmental offset; and / or updating the linkage parameters of the linkage system within the integrated control strategy.

[0096] Upon receiving continuously collected cabin environmental data, the system first compares the data with the comfort zones defined in the integrated control strategy. Then, it calculates the environmental offset based on the direction and magnitude of the deviation, and maps this offset to corresponding parameter correction values.

[0097] For example, environmental offsets include at least one of the following: temperature offset, humidity offset, air quality offset, etc.

[0098] For example, when the temperature deviation is large, the fresh air volume of the vehicle's fresh air system can be increased simultaneously and the linkage strength of the linkage system can be improved.

[0099] For example, when the humidity or fogging trend shifts significantly, the dehumidification or defogging linkage parameters of the linkage system can be increased.

[0100] For example, when the air quality deviation is large, the purification level of the vehicle's fresh air system can be increased or the high-efficiency filtration mode can be switched.

[0101] The updating of adjustment parameters and linkage parameters can be accomplished by a mapping table, rule base, or weighted function stored in the controller to obtain the updated adjustment parameters and linkage parameters. Furthermore, after obtaining the updated adjustment parameters and linkage parameters, they are output to the vehicle-mounted fresh air system and the linkage system.

[0102] The integrated control strategy can adjust the fresh air and linkage control content according to the real-time cabin status, so that the vehicle fresh air system and linkage system maintain the same adjustment rhythm, thereby making the passenger cabin environment more in line with the current needs and reducing the lag and adaptation deviation of the fixed strategy under complex working conditions.

[0103] In one possible implementation, the local environmental data includes in-cabin environmental data and out-of-cabin environmental data. Acquiring multi-source environmental data includes: acquiring in-cabin environmental data through a first sensing module deployed inside the vehicle; acquiring out-of-cabin environmental data through a second sensing module deployed outside the vehicle; and acquiring meteorological environmental data characterizing the area where the vehicle is located through a communication connection between a communication terminal deployed inside the vehicle and a cloud-based meteorological platform.

[0104] The first sensing module, the second sensing module, and the communication terminal output cabin environment data, cabin environment data, and meteorological environment data, respectively. Together, the first sensing module, the second sensing module, and the communication terminal constitute multi-source environmental data.

[0105] Optionally, the first sensing module includes at least one of the following sensors: in-vehicle temperature and humidity sensor, carbon dioxide sensor, volatile organic compound sensor, occupant infrared detection sensor, and cabin fog sensor.

[0106] Optionally, the second sensing module includes at least one of the following sensors: outdoor temperature and humidity sensor, PM2.5 / PM10 particulate matter sensor, air quality sensor, rain and snow sensor, dust sensor, and light sensor.

[0107] Optionally, multi-source environmental data can be obtained by performing time synchronization and validity verification on the data from the first sensing module, the second sensing module, and the communication terminal.

[0108] By acquiring multi-source environmental data, the local conditions inside and outside the passenger cabin are made complementary to the regional meteorological conditions, thus providing a more complete environmental basis for fresh air conditioning and linkage control.

[0109] By acquiring multi-source environmental data, it is possible to simultaneously obtain three types of environmental information: in-cabin, out-of-cabin, and regional meteorological information. The scope of environmental perception is expanded from local to regional scale, and the information on which scenario determination is based is more complete. As a result, the response of the crew cabin environmental control to high temperature, rain, dust and sudden weather changes is more in line with actual working conditions.

[0110] In one possible implementation, the integrated control strategy is output to the corresponding vehicle ventilation system and linkage system via the vehicle's bus.

[0111] The bus is used to transmit control information between the main control unit that generates the integrated control strategy and the vehicle's ventilation system and linkage system. The bus can be a Controller Area Network (CAN) bus within the vehicle's internal communication network or a communication link compatible with the CAN bus. The bus is used to carry strategy data frames, status response frames, and execution feedback frames.

[0112] After the integrated control strategy is transmitted via the bus, the vehicle's fresh air system adjusts the air volume, internal / external circulation switching status, and purification intensity according to the adjustment parameters in the integrated control strategy. The linkage system controls the air conditioning, defogging, or other cooperating components according to the linkage parameters in the integrated control strategy.

[0113] For example, the in-vehicle fresh air system includes an air damper, a fan, and an air duct, with multi-stage purification units deployed within the air duct. The integrated system includes an air conditioning system and a defogging system. The comprehensive control strategy includes: In high-temperature scenarios, the main control unit sends a coordinated command to the air conditioning system via the CAN bus, causing the air conditioning compressor to start in advance and adjust the evaporator temperature to actively pre-cool the incoming fresh air, preventing hot airflow from directly entering the passenger compartment and causing thermal shock. In low-temperature and frigid scenarios, the integrated air conditioning system switches to heating mode, using the warm air core to preheat the incoming fresh air, preventing cold air from directly blowing on the occupants and reducing the risk of temperature and humidity imbalance in the cabin due to the convergence of hot and cold airflows. In high-humidity or rainy / snowy weather scenarios, while starting fresh air exchange, the defogging system is simultaneously triggered by the integrated unit, activating the windshield heating wires and rearview mirror heating functions, and coordinating with the air conditioning compressor's dehumidification mode to quickly remove fog from the glass surface, ensuring clear driving visibility. Simultaneously, fresh air is continuously introduced to replace the humid air in the cabin, maintaining the humidity in the passenger compartment within a comfortable range.

[0114] In addition, when the vehicle's CAN bus obtains information about the vehicle's driving conditions in a tunnel or congested road section, the body control system will automatically reduce the opening of the dual-stage combined air damper to reduce the proportion of fresh air introduced, or switch to full internal circulation mode as needed, and simultaneously improve the working efficiency of the activated carbon adsorption layer in the multi-stage purification unit, thereby effectively blocking the intrusion of high-concentration exhaust gas and harmful aerosols into the cabin. After driving to an open or clean road section, the fresh air function will be automatically restored, realizing active health protection and thermal comfort protection in all scenarios of the cabin environment.

[0115] For example, an in-vehicle fresh air system includes an air damper, a fan, and an air duct, with multi-stage purification units deployed within the air duct. The linkage system includes an air conditioning system and a defogging system. Accordingly, the adjustment parameters of the in-vehicle fresh air system include: the target opening degree of the air damper; the target rotation speed of the fan; and the purification level of the multi-stage purification units. The linkage parameters of the linkage system include the air conditioning coordination parameters of the air conditioning system and the defogging coordination parameters of the defogging system. The target opening degree of the air damper, the target rotation speed of the fan, and the purification level of the multi-stage purification units are output to the in-vehicle fresh air system via the vehicle's bus. The air conditioning coordination parameters are output to the air conditioning system via the vehicle's bus. The defogging coordination parameters are output to the defogging system via the vehicle's bus.

[0116] The bus can send the comprehensive control strategy to the corresponding execution object synchronously, or send it to the vehicle fresh air system first and then to the linkage system according to a preset timing, or send it to both in the same communication cycle, so as to ensure that the two types of execution units, the vehicle fresh air system and the linkage system, receive the same source control content.

[0117] Optionally, the vehicle-mounted fresh air system and the linkage system are each equipped with a communication interface. The communication interface is electrically connected to the bus and executes the corresponding action after parsing the received control frame.

[0118] When the parsed control content contains multiple execution fields, the vehicle-mounted fresh air system can call the fan control module, damper drive module, and linkage execution module respectively according to the field mapping relationship.

[0119] Through the above methods, the integrated control strategy is uniformly transmitted to the vehicle's fresh air system and linkage system, enabling them to perform environmental adjustment operations based on the same control source. This results in coordinated actions such as ventilation, purification, and defogging within the vehicle. Because control information is directly transmitted through the vehicle's internal communication network, the fresh air system and linkage system can respond within the same control cycle, reducing command transmission delays and ensuring that the environmental adjustments in the passenger compartment are consistent with the current scenario, thereby improving the synchronicity and stability of environmental control.

[0120] In one possible implementation, the vehicle-mounted fresh air system includes an air damper, a fan, and an air duct, wherein a multi-stage purification unit is deployed within the air duct. The adjustment parameters of the vehicle-mounted fresh air system include: the target opening degree corresponding to the air damper; the target rotation speed corresponding to the fan; and the purification level corresponding to the multi-stage purification unit. Controlling the vehicle-mounted fresh air system to perform occupant cabin environment adjustment operations includes: controlling the air damper to adjust to the target opening degree; controlling the fan to adjust to the target rotation speed; and controlling the multi-stage purification unit to start at the corresponding purification level.

[0121] Upon receiving the integrated control strategy, the target opening degree of the damper is converted into an opening and closing angle command for the actuator motor, driving the damper to rotate to the corresponding position. The target speed of the fan is converted into a motor drive frequency or duty cycle command, causing the fan to operate according to the set airflow. The purification level is converted into start / stop control signals for multi-stage purification units, enabling modules such as pre-filters, high-efficiency filters, adsorption purification, or ion purification to operate according to the set levels.

[0122] Optionally, the damper can be an electric flap structure, the fan can be a brushless DC motor structure, and the multi-stage purification unit can be set at the air inlet, middle or outlet of the air duct, and installed by means of housing snap-fit, screw fixing or guide rail sliding, so as to facilitate adaptation according to the vehicle layout in actual application. This application does not limit this.

[0123] During the operation of the passenger cabin environmental conditioning system, the damper opening, fan speed, and purification level are synchronously controlled, ensuring that the airflow, delivery intensity, and purification intensity entering the passenger cabin match the current environmental scenario, thus maintaining consistency between fresh air introduction and air treatment. By jointly controlling the dampers, fans, and multi-stage purification units, corresponding fresh air conditions can be output under different pollution levels and different cabin requirements.

[0124] The vehicle-mounted fresh air system can coordinate the adjustment of air intake ratio, air supply intensity and purification intensity with a single control link, making the passenger cabin environment more in line with current needs and giving the air handling process a clearer hierarchical control relationship.

[0125] Optionally, the air damper in the vehicle-mounted fresh air system adopts a two-stage combined continuous adjustment mechanism, which can further achieve stepless linear adjustment of the fresh air introduction ratio within the range of 0% to 100%, on top of the three basic modes of external circulation, internal circulation, and mixed fresh air, thereby precisely controlling the amount of external air mixed in. The two-stage combined continuous adjustment mechanism differs from the traditional single damper fully open or fully closed mode, enabling three working modes: full internal circulation, full external circulation, and 0%~100% continuously adjustable mixed fresh air, precisely controlling the fresh air introduction ratio.

[0126] Optionally, the fan matched with the damper no longer relies on a fixed speed setting, but adopts a stepless variable frequency speed control motor, which can smoothly change the speed according to the real-time instructions issued by the main control unit, so that the air volume can be continuously and gradually changed, achieving smooth air volume change, completely eliminating the airflow impact and step noise generated when switching traditional gears, and avoiding sudden changes in air volume from affecting comfort.

[0127] Optionally, the air duct of the vehicle's fresh air system is not a single air intake duct, but rather combines the front fresh air intake duct with the exhaust duct independently arranged at the rear of the passenger compartment, forming a directional convection field that supplies fresh air at the front and exhausts stale air at the rear, greatly improving the ventilation efficiency of the entire cabin.

[0128] Inside the fresh air intake duct, a multi-stage purification unit is deployed along the air intake direction. This multi-stage purification unit comprises four stages arranged in series: a pre-filter, a high-efficiency particulate air filter, an activated carbon adsorption layer, and a negative ion generator. Based on the real-time detection levels of pollutants inside and outside the vehicle, the multi-stage purification unit can differentiate and activate the corresponding purification layers accordingly. Furthermore, its activation level and purification power are adaptively matched to the real-time airflow of the continuously variable fan and the current opening of the dual-stage dampers, ensuring the most stable and healthiest cabin air quality control with the most reasonable energy consumption under different operating conditions.

[0129] Optionally, based on multi-source environmental data, the real-time detection level of pollutants inside and outside the vehicle is determined. For example, the real-time detection levels of pollutants inside and outside the vehicle include: light pollution, moderate pollution, and heavy pollution. Further, when the real-time detection level is light pollution, only the primary filter of the multi-stage purification unit is activated. When the real-time detection level is moderate pollution, both the primary filter and the activated carbon adsorption layer of the multi-stage purification unit are activated. When the real-time detection level is heavy pollution, the primary filter, activated carbon adsorption layer, high-efficiency particulate air filter, and negative ion generator of the multi-stage purification unit are activated.

The comprehensive control strategy includes the adjustment parameters of the vehicle-mounted fresh air system and the linkage parameters of the linkage system; and outputs the comprehensive control strategy to the corresponding vehicle-mounted fresh air system and linkage system to control the vehicle-mounted fresh air system and linkage system to perform passenger cabin environment adjustment operations.

[0133] In one possible implementation, during the process of performing the crew cabin environment adjustment operation, the processing module 402 is also used to: continuously collect cabin environment data in the crew cabin; if the cabin environment data deviates from the comfort range corresponding to the integrated control strategy, trigger a correction mechanism to dynamically adjust the integrated control strategy.

[0134] In one possible implementation, the processing module 402 is further configured to: obtain an environmental offset by determining the deviation between the cabin environment data and the comfort zone corresponding to the integrated control strategy; update the adjustment parameters of the vehicle-mounted fresh air system within the integrated control strategy based on the environmental offset; and / or update the linkage parameters of the linkage system within the integrated control strategy.

[0135] In one possible implementation, the local environmental data includes in-cabin environmental data and out-of-cabin environmental data. The acquisition module 402 is used to: acquire in-cabin environmental data through a first sensing module deployed inside the vehicle; acquire out-of-cabin environmental data through a second sensing module deployed outside the vehicle; and acquire meteorological environmental data characterizing the area where the vehicle is located through a communication connection between a communication terminal deployed inside the vehicle and a cloud-based meteorological platform.

[0136] In one possible implementation, the processing module 402 is specifically used to: output the comprehensive control strategy to the corresponding vehicle ventilation system and linkage system via the bus inside the vehicle.

[0137] In one possible implementation, the vehicle-mounted fresh air system includes an air damper, a fan, and an air duct, wherein a multi-stage purification unit is deployed within the air duct. The adjustment parameters of the vehicle-mounted fresh air system include: the target opening degree corresponding to the air damper; the target rotation speed corresponding to the fan; and the purification level corresponding to the multi-stage purification unit. The processing module 402 is specifically used to: control the air damper to adjust to the target opening degree; control the fan to adjust to the target rotation speed; and control the multi-stage purification unit to start at the corresponding purification level.

Figure 5 As shown, the electronic device 50 provided in this embodiment includes at least one processor 501 and a memory 502. Optionally, the device 50 further includes a communication component 503. The processor 501, memory 502, and communication component 503 are connected via a bus 504.

[0140] In a specific implementation, at least one processor 501 executes computer execution instructions stored in memory 502, causing at least one processor 501 to perform the above-described method.

[0141] The specific implementation process of processor 501 can be found in the above method embodiments, and its implementation principle and technical effect are similar. It will not be repeated here.

[0142] A passenger cabin environment control system includes: the passenger cabin environment control device provided above, and an on-board fresh air system and a linkage system that are communicatively connected to the passenger cabin environment control device via a bus. The on-board fresh air system includes a damper, a fan, and an air duct, wherein a multi-stage purification unit is deployed within the air duct. The linkage system includes at least one of an air conditioning system, a defogging system, and a vehicle body control system. The passenger cabin environment control device is used to generate a comprehensive control strategy based on multi-source environmental data and operating condition data, and to send adjustment parameters and linkage parameters of the comprehensive control strategy to the on-board fresh air system and the linkage system, respectively.

[0143] By connecting the passenger cabin environmental control equipment with the vehicle's fresh air system and linkage system via a bus, environmental perception, strategy generation, and execution response can be integrated into the same control link. A comprehensive control strategy is generated based on multi-source environmental data and operating condition data, simultaneously considering indoor and outdoor air quality, weather changes, and vehicle operating status, thus avoiding adjustment lag caused by triggering only a single parameter. The air dampers, fans, ducts, and multi-stage purification units in the vehicle's fresh air system operate collaboratively according to adjustment parameters, enabling the fresh air ratio, air volume, and purification intensity to dynamically match the scene. The linkage system, based on linkage parameters, works in conjunction with at least one of the air conditioning system, defogging system, and vehicle control system to adjust, thereby taking into account air quality, thermal comfort, glass anti-fogging, and energy consumption control. Therefore, it is more suitable for complex operating conditions such as congestion, tunnels, high temperature and humidity, rain, and dust storms.

[0145] By deploying the aforementioned passenger compartment environmental control system within the vehicle, regional meteorological information, local vehicle environmental information, and vehicle operating status can be uniformly integrated into the cabin environmental control chain. This allows for targeted adjustments to fresh air intake, internal and external air circulation, air volume, and purification intensity based on the current driving scenario and external climate conditions. The system can also coordinate with air conditioning and defogging devices to simultaneously regulate air quality, control thermal comfort, and prevent glass fogging. This reduces control lag and strategy fragmentation issues in complex weather, congested traffic, or tunnel conditions, thus balancing passenger comfort, cabin air cleanliness, and overall vehicle energy consumption.
