[0021] It should be noted that, Figure 1 The illustrated scenario of the ventilation control method is merely an example. The implementation environment of the ventilation control method described in this application is for the purpose of more clearly illustrating the technical solution of this application and does not constitute a limitation on the technical solution provided in this application.

[0022] The solutions provided in this application are specifically illustrated through the following embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] This embodiment will be described from the perspective of a ventilation control device, which can be integrated into an electronic device, which can be a terminal and / or a server, and this application does not limit it.

[0024] Please see Figure 2 , Figure 2 This is a schematic flowchart of a ventilation control method provided in an embodiment of this application. The ventilation control method may include the following step S101: Step S101: Based on the ventilation strategy matched with the vehicle's parking association information, when the odor perception information in the vehicle cabin indicates an abnormality, the ventilation control of the vehicle cabin is performed.

[0025] Among them, parking-related information refers to the information associated with a vehicle when it is in a parked state (also known as parking status or parking mode).

[0026] Parking-related information may include, but is not limited to, power-off status, power-off duration, and parking duration. Power-off status characterizes the power supply mode of the vehicle's power system. Power-off status can indicate that the vehicle's power system is off or has entered a low-power sleep mode. Power-off status can also indicate that the vehicle's power system is not off, meaning the vehicle's power system is maintaining a normal power supply mode. Power-off duration refers to the duration for which the power-off status remains in the indicated power-off state. Parking duration indicates the length of time the vehicle remains stationary from the moment it stops moving, regardless of whether the vehicle is powered off.

[0027] Among them, the ventilation strategy refers to the cabin ventilation control scheme. The ventilation strategy specifies at least one or more of the following: ventilation timing, ventilation duration, ventilation air volume, ventilation mode, and ventilation level.

[0028] Among them, odor perception information is used to characterize the air quality or odor presence in the vehicle cabin.

[0029] Odor perception information includes at least one of the following: odor type and odor concentration. Odor type includes, but is not limited to, volatile organic compounds (VOCs) and carbon dioxide. VOCs refer to organic compounds with high saturated vapor pressure, low boiling point, and high volatility at room temperature. Common types include formaldehyde, acetaldehyde, acrolein, benzene, toluene, xylene, ethylbenzene, and styrene. Odor concentration is a gas content indicator used to characterize the odor or air quality in the cabin. Examples include VOC concentration, carbon dioxide concentration, or other gas concentration indicators that can characterize the air quality or odor level in the cabin.

[0030] Odor perception information indicates an anomaly when the odor type includes a specified odor type, and / or the odor concentration exceeds the target concentration of the corresponding odor. The specified odor type is used to indicate VOCs (such as formaldehyde, acetaldehyde, acrolein, benzene, toluene, xylene, ethylbenzene, styrene, etc.). The target concentration refers to the concentration used to measure whether the gas is abnormal under the corresponding odor type.

[0031] For example, if the odor type includes carbon dioxide and the carbon dioxide concentration exceeds the target concentration, the odor perception information indicates an anomaly. If the odor type includes carbon dioxide but the carbon dioxide concentration does not exceed the target concentration, the odor perception information indicates normal. Similarly, if the odor type includes carbon dioxide and the carbon dioxide concentration exceeds the target concentration, or if the odor type includes a specified VOC, the odor perception information indicates an anomaly. If the odor type includes carbon dioxide but the carbon dioxide concentration does not exceed the target concentration, and the odor type does not include a specified VOC, the odor perception information indicates normal. These specific indications can be adjusted according to actual circumstances and are not limited here.

[0032] It is understandable that odor perception information is not limited to the above content; it may also include the odor abnormality level, that is, the degree of abnormality indicated by the odor perception information, which will not be elaborated here.

[0033] The ventilation control method of this application embodiment can control the ventilation of the vehicle cabin when the odor perception information in the vehicle cabin indicates abnormality, by matching a ventilation strategy with the vehicle's parking association information. Thus, by matching a differentiated ventilation strategy with parking association information, refined ventilation control can be implemented for different parking scenarios when abnormal cabin odors occur, effectively improving cabin air quality and significantly enhancing the targeting and effectiveness of ventilation control.

[0034] It should be noted that there are multiple ways to obtain odor perception information, and the specific methods can be adjusted according to the actual situation; no restrictions are imposed here.

[0035] Alternatively, odor perception information can be obtained through sensors installed in the vehicle cabin.

[0036] Specifically, odor perception information is directly collected by sensors installed inside the vehicle cabin.

[0037] Optionally, feature analysis can be performed on the sensor data acquired by sensors installed in the vehicle cabin to obtain odor perception information.

[0038] Specifically, raw sensor data is first acquired through sensors installed in the vehicle cabin, and then the sensor data is analyzed for features to obtain the required odor sensing information.

[0039] The sensors installed in the vehicle compartment include at least a gas sensor for detecting the composition of the gas inside the compartment. In addition, temperature and humidity sensors can be further configured as needed to enrich the dimensions of the sensing data and improve detection reliability.

[0040] As a specific implementation method, an array sensor can be used to collect cabin odor sensing information. This array sensor includes two or more gas sensors, as well as temperature and humidity sensors. During operation, the array sensor can extract the characteristic changes of each component sensor under the odor environment and use machine learning algorithms to fuse and analyze these multi-dimensional features, thereby identifying the type of odor present in the cabin. The physical arrangement of the array sensor can be adaptively adjusted according to the spatial structure, airflow distribution, and actual installation conditions within the vehicle cabin. For a single gas sensor, it mainly has high recognition sensitivity for specific types of gases, such as a formaldehyde sensor for formaldehyde gas, or a carbon monoxide sensor for carbon monoxide gas. However, gas sensors often exhibit some cross-response for non-target gases. Considering the current lack of mature odor sensors that can directly output universal odor recognition results, this application fully utilizes the aforementioned cross-response characteristics. By collecting comprehensive response data from multiple gas sensors under the same odor environment and establishing a mapping relationship between sensor response patterns and odor types based on a machine learning model, it achieves effective identification of various complex odors.

[0041] It should be noted that the detection values ​​of gas sensors are easily disturbed by changes in ambient temperature and humidity. Therefore, temperature and humidity sensors configured in the array sensor can be used to compensate and correct the detection data of the gas sensors, eliminating or reducing measurement deviations caused by temperature and humidity changes and ensuring the accuracy of odor perception information.

[0042] Furthermore, under high-temperature exposure, the rate of volatile organic compound (VOC) release from interior trim materials accelerates significantly, leading to an increase in cabin odor concentration. Therefore, temperature information can also be used as an indirect monitoring method to assess the risk of cabin odor deterioration. Based on existing temperature and humidity sensor resources in the array sensor, temperature information can also be used as one of the criteria for controlling the air conditioning system. For example, when the cabin temperature is too high, the air conditioning compressor can be activated for cooling. This can suppress the release of VOCs from interior materials, mitigating odor generation at its source, and also maintain cabin temperature comfort when the vehicle is in rest mode.

[0043] The aforementioned array sensor contains at least two gas sensors, the specific types of which can be flexibly selected according to detection requirements, including but not limited to alkene sensors, ammonia sensors, organic alcohol sensors, alkane sensors, aldehyde sensors, benzene sensors, sulfide sensors, organic ketone sensors, sulfur series sensors, organic amine sensors, aldehyde series sensors, carbon monoxide sensors, carbon dioxide sensors, and total volatile organic compound sensors. Preferably, alkene sensors, ammonia sensors, organic alcohol sensors, alkane sensors, aldehyde sensors, benzene sensors, and organic ketone sensors are used. This preferred combination can identify at least a variety of common in-vehicle odors such as amine odor, foam odor, glue odor, leather odor, solvent odor, plastic odor, genuine leather odor, residual food odor, sweat odor, gasoline odor, acid odor, perfume odor, smoke odor, and fishy odor, thereby improving the accuracy of odor recognition.

[0044] In some embodiments, the parking-related information mentioned above includes the power-off status.

[0045] The above step of "controlling the ventilation of the vehicle's cabin" may include: controlling the ventilation of the vehicle's cabin according to a first ventilation strategy when the power-down indicator is not powered on; or, controlling the ventilation of the vehicle's cabin according to the first ventilation strategy when the power-down indicator is not powered on and a biological object is present in the vehicle's cabin.

[0046] Biological objects include, but are not limited to, living biological objects such as passengers and pets; there are no restrictions here.

[0047] The first ventilation strategy is used to indicate the ventilation strategy that matches the parking-related information that the power-off status indicator is not powered off.

[0048] Optionally, the first ventilation strategy may include controlling the vehicle's ventilation module to operate at a ventilation level that matches the degree of abnormality indicated by the odor perception information.

[0049] The ventilation module may include, but is not limited to, the vehicle's air conditioning and blower. The blower provides airflow power to drive the airflow inside the cabin or to achieve air exchange between the inside and outside of the cabin; the air conditioning is used to regulate the temperature and humidity of the air during the ventilation process, or to provide support such as cooling, heating and circulation mode switching as needed, so as to improve air quality while maintaining the comfort of the cabin environment.

[0050] The aforementioned ventilation settings are used to characterize the ventilation intensity or airflow output level of the ventilation module. As an exemplary implementation, a positive correlation can be established between the degree of abnormality indicated by the odor perception information and the ventilation setting. That is, the higher the degree of abnormality indicated by the odor perception information, the higher the corresponding ventilation setting, and the greater the airflow output by the ventilation module, thereby enabling faster removal or dilution of odorous air in the cabin. Conversely, when the degree of abnormality indicated by the odor perception information is low, a lower ventilation setting can be used to reduce energy consumption and operating noise while meeting the air quality improvement requirements.

[0051] In one specific implementation, the degree of odor abnormality can be divided into multiple levels based on odor perception information, such as no odor, slight abnormality, moderate abnormality, and severe abnormality. Correspondingly, the ventilation level can be set to low, medium, and high. When the odor perception information indicates no odor or slight abnormality, the ventilation module can operate at low level or intermittently; when indicating moderate abnormality, the ventilation module operates continuously at medium level; when indicating severe abnormality, the ventilation module rapidly ventilates at high level and can also activate the air conditioning's external circulation mode to accelerate the exchange efficiency of air between the cabin and the outside.

[0052] Thus, by dynamically matching the ventilation level according to the degree of odor abnormality, the above-mentioned control method can ensure the ventilation effect while avoiding unnecessary energy waste and achieve precise control of cabin air quality.

[0053] It should be noted that the first ventilation strategy is not limited to the above. For example, a time window mechanism can be introduced to manage the validity of odor perception information. Specifically, a valid time window can be set for odor perception information, and only odor perception information acquired within the valid time window is used for ventilation level matching. When the valid time window is exceeded, the array sensor is re-triggered to collect data to update the odor perception information. Through the above timeliness control, it is possible to avoid relying on outdated historical odor data to make ventilation decisions, ensuring the consistency between the ventilation level and the real-time air quality in the cabin. The specific content of the first ventilation strategy can be adjusted according to the actual situation, and is not limited here.

[0054] In some embodiments, the parking-related information may also include the duration of power-off.

[0055] The above step of "controlling the ventilation of the vehicle's cabin" may include: controlling the ventilation of the vehicle's cabin according to a second ventilation strategy when the power-off state indicates power-off and the power-off duration is less than the target duration; and controlling the ventilation of the vehicle's cabin according to a third ventilation strategy when the power-off state indicates power-off and the power-off duration is greater than or equal to the target duration.

[0056] The target duration is used to indicate the target power-down duration that distinguishes the timing of the execution of the second and third ventilation strategies.

[0057] The second ventilation strategy is used to indicate a ventilation strategy that matches the parking-related information that the power-off state indicates power-off and the power-off duration is less than the target duration.

[0058] In this embodiment, the second ventilation strategy adopts a graded and progressive control method to ensure ventilation effect while optimizing energy consumption and operating noise.

[0059] Optionally, the second ventilation strategy may include: controlling the vehicle's ventilation module to operate at the first ventilation level; if the odor perception information obtained after a preset operating time indicates an abnormality, controlling the vehicle's ventilation module to operate at the second ventilation level until the termination condition is met; wherein, the ventilation capacity of the second ventilation level is stronger than that of the first ventilation level, and the termination condition includes at least one of the following: the odor perception information indicates normal, the second ventilation level is the highest ventilation level, and the power-off time is greater than the target time.

[0060] Specifically, the vehicle's ventilation module operates at the first ventilation setting. This first setting can be an initial setting that matches the level of abnormality indicated by the current odor perception information, or it can be a system-preset default starting setting. Its ventilation capacity is relatively low, suitable for exploratory ventilation in the early stages of odor or when the abnormality is mild. After the ventilation module operates continuously at the first ventilation setting for a preset time, odor perception information is collected again to assess the improvement in cabin air quality.

[0061] If the odor perception information still indicates an abnormality after a preset operating time, it means that the odor in the cabin has not been effectively eliminated or diluted. At this time, the vehicle's ventilation module is controlled to operate at the second ventilation level through the aforementioned second ventilation strategy. The ventilation capacity of the second ventilation level is stronger than that of the first ventilation level. As an example, the strength of the ventilation capacity can be characterized by the blower speed, airflow output level, or cabin air exchange rate per unit time in the ventilation module. Compared to the first ventilation level, the second ventilation level has a higher blower speed, a larger airflow output, or a faster air exchange rate, thereby improving odor removal efficiency and the speed of air quality improvement.

[0062] During the operation of the ventilation module at the second ventilation level, it continuously monitors whether the termination conditions are met.

[0063] Optionally, the termination condition may include odor perception information indicating normal operation. That is, if the odor perception information obtained again by the array sensor or related detection device indicates that the odor in the cabin has been eliminated or the air quality has returned to normal levels, the current ventilation control process can be terminated, or the ventilation module can be controlled to operate at a lower speed or even stop working.

[0064] Optionally, the termination condition may include the second ventilation level being the highest ventilation level. That is, the ventilation module has reached the highest ventilation intensity supported by the system, even if the odor sensing information still indicates an anomaly. Considering that there are no further adjustable levels to increase the ventilation capacity, or for the purpose of protecting the ventilation module and controlling energy consumption, the current state is used as the termination condition, and further upgrading of the ventilation level is stopped. In an optional implementation, after reaching the highest ventilation level, the ventilation module can maintain that level for another preset duration, or switch to other preset anomaly handling procedures.

[0065] Optionally, the termination condition may include a power-down duration greater than or equal to a target duration. That is, if the vehicle has been in a power-down state for a longer period than the preset target duration, then considering factors such as vehicle power supply range, battery power protection, or the maximum allowable power-down ventilation time set by the user, the current ventilation control is terminated, and the ventilation module is stopped working to avoid excessive consumption of vehicle power.

[0066] Thus, through the above-mentioned graded and progressive ventilation strategy, initial ventilation can be carried out at a relatively low ventilation level in the early stage of odor abnormality. If the air quality does not meet the standard within the preset time, the ventilation intensity can be gradually increased. This effectively improves the cabin air quality while avoiding unnecessary energy consumption and operating noise caused by using a high level of operation from the beginning, achieving a balance between the economy and effectiveness of ventilation control.

[0067] It should be noted that the second ventilation strategy is not limited to the above. For example, a downgrade back-off logic for the ventilation level can also be introduced. For instance, if the degree of abnormality indicated by the odor sensing information decreases but still does not indicate normality during the operation of the ventilation module at the second ventilation level, the ventilation module can be controlled to back-off to the first ventilation level or the intermediate ventilation level to continue working until the odor sensing information indicates normality, thereby avoiding the noise and energy consumption caused by continuous operation at the high level.

[0068] The third ventilation strategy is used to indicate the ventilation strategy that matches the parking association information that the power-off state indicates power-off and the power-off duration is greater than or equal to the target duration.

[0069] When parking-related information indicates that the vehicle is powered off and the power-off time has reached or exceeded the preset target time, the system determines that the vehicle is in a long-term closed parking condition and there is a risk of odor accumulation in the cabin. At this time, a ventilation control strategy combining periodic detection and condition triggering is activated.

[0070] The aforementioned target duration can be preset based on the vehicle's battery capacity characteristics, the allowable power consumption budget during power-off, and the accumulation pattern of odors in the cabin under typical conditions. As an example, the target duration can be set to 30 minutes, 60 minutes, or 120 minutes. Before the target duration is reached, the system can temporarily refrain from activating periodic odor detection to avoid unnecessary power consumption due to frequent sensor wake-ups and ventilation module activation in the short period immediately after power-off. Once the target duration is reached or exceeded, it indicates that the vehicle has been in a closed, parked state for an extended period. At this point, the periodic detection mechanism is activated to promptly detect and address any potential odor accumulation in the cabin.

[0071] Optionally, the third ventilation strategy may include: acquiring odor perception information according to a target cycle, and controlling the vehicle's ventilation module to operate at the first ventilation level when the odor perception information indicates an abnormality.

[0072] The target period refers to the time interval between two consecutive odor sensing information acquisition operations, which can be adaptively set according to the power constraints of the power-off state. In one implementation, the target period can be set to a fixed interval such as five minutes, ten minutes, or thirty minutes; in another implementation, the target period can also be related to the power-off duration. For example, as the power-off duration increases, the target period can be appropriately shortened to capture odor changes in a timely manner. Odor sensing information can be acquired by waking up the array sensor in a low-power monitoring state. After completing a single sampling, the array sensor can re-enter a low-power standby state, thereby reducing the average power consumption during the power-off period.

[0073] After acquiring odor sensing information according to the target cycle, the system analyzes the information to determine if it indicates any abnormality. If the odor sensing information indicates normal air quality (i.e., the cabin air quality is within an acceptable range), the ventilation module remains stopped, and the system continues to wait for the next target cycle to begin detection again. If the odor sensing information indicates abnormal air quality (i.e., an odor has been generated in the cabin or the concentration of volatile organic compounds exceeds the standard), the ventilation module controls the vehicle to operate at the first ventilation level. The first ventilation level is a relatively low level, with a blower speed or airflow output lower than the medium to high levels. This allows for initial airflow and odor dilution in the cabin with lower power consumption when the power is off, preventing rapid battery drain due to high load operation.

[0074] It should be noted that the third ventilation strategy is not limited to the above. For example, a ventilation duration can also be introduced. If the odor sensing information indicates an abnormality, the third ventilation strategy can control the ventilation module to operate continuously at the first ventilation level for a first preset duration. If the odor sensing information still indicates an abnormality after the first preset duration has ended and after a target cycle, the single continuous operating duration of the ventilation module can be extended to a second preset duration, which is longer than the first preset duration. In this way, while maintaining low-noise operation at a low level, the total ventilation volume is increased by extending the single ventilation time, thereby gradually diluting the odor in the cabin without increasing the instantaneous airflow.

[0075] It should be noted that the first, second, and third ventilation strategies are not limited to the above-mentioned contents. The key point is that the first, second, and third ventilation strategies are different from each other.

[0076] To facilitate a better understanding of the ventilation control method provided in the embodiments of this application, the following description is provided in conjunction with specific embodiments.

[0077] To address the issues of odor accumulation in the cabin when the vehicle is parked due to the ventilation system being shut down, and the inability to achieve a reasonable balance between energy consumption and air quality monitoring after the vehicle is powered off, this application proposes an in-cabin ventilation system based on array sensor sensing and a multi-scenario ventilation strategy to solve these problems.

[0078] Specifically, please refer to Figure 3 and Figure 4 This application provides an in-cabin ventilation system that can automatically control ventilation based on odor conditions while the vehicle is parked. Figure 4 As shown, the cabin ventilation system includes a sensing module, a domain controller (also known as a domain controller), and a ventilation module. The sensing module is communicatively connected to the domain controller, and the ventilation module is also communicatively connected to the domain controller.

[0079] The sensing module consists of an array of sensors, including multiple gas sensors and temperature and humidity sensors. By extracting changes in the output characteristics of each sensor and processing and analyzing the collected data using machine learning algorithms, the type of odor inside the cabin can be identified. Machine learning can employ neural network algorithms to efficiently model and classify the data collected by the sensors, achieving accurate identification of odor types. The array sensors can be deployed in locations close to the occupants, such as seats and B-pillars, and connected to a constant power supply for more accurate and real-time perception of the odor conditions inside the occupant cabin.

[0080] The ventilation module can consist of the vehicle's existing air conditioning system (mainly including a blower) and a pressure relief valve located in the trunk, thereby forming a ventilation system. Figure 3The airflow circulation channel shown enables the orderly flow and renewal of air inside the cabin.

[0081] The domain controller is communicatively connected to both the sensing module and the ventilation module. It receives messages from the sensing module and sends control messages to the ventilation module based on the identification results to control the working status of components such as air conditioners, blowers, and compressors, thereby achieving automatic ventilation control for different odors and operating conditions.

[0082] In addition, differentiated ventilation strategies have been developed for different vehicle parking scenarios to effectively improve air quality in the passenger compartment, increase ventilation efficiency, and reduce energy consumption.

[0083] For example, in a rest scenario, the vehicle is parked but there are still occupants (i.e., biological entities) inside, and the vehicle is not powered off. The sensing module collects odor, VOC, and carbon dioxide information in real time: odor is identified by an array of sensors, and VOC and carbon dioxide are measured by the corresponding gas sensors in the array. When an odor is detected, or either VOC or carbon dioxide exceeds a threshold (e.g., the carbon dioxide threshold range is [X1, X2] ppm, and the detection method is direct measurement by the carbon dioxide sensor), the sensing module sends a message to the domain controller, which then starts or adjusts the air conditioning blower to perform external air circulation. Different air quality levels correspond to different ventilation levels, which are matched and controlled through a preset mapping table.

[0084] In short-term parking mode, the vehicle is powered off, but the sensing module continues to operate for 2 hours. During this period, if an odor or VOC exceeding the threshold is detected (carbon dioxide is not detected), the controller activates the blower for ventilation, defaulting to the lowest setting for slow ventilation. If the odor or VOC does not improve after 10 minutes of continuous ventilation, the controller increases the blower speed by one level to enhance the ventilation effect.

[0085] In long-term parking mode, if the vehicle is powered off and not powered back on within 2 hours, the sensing module enters sleep mode to save energy. At this time, the sensing module can be woken up at preset daily, weekly, or monthly cycles, with each cycle lasting 2 hours. During wake-up, if an odor or VOC exceeding the threshold is detected (but carbon dioxide is not detected), the controller starts the blower for ventilation, using only the lowest setting for slow ventilation, and then enters sleep mode again after a period of continuous ventilation (e.g., 2 hours).

[0086] When the vehicle's battery level falls below a preset threshold, the sensing module stops working, and the automatic ventilation function is turned off.

[0087] In addition, differentiated ventilation strategies have been developed for different vehicle parking scenarios to effectively improve air quality in the passenger compartment, increase ventilation efficiency, and reduce energy consumption.

[0088] For example, in a rest scenario, the vehicle is parked but there are still occupants inside, and the vehicle is not powered off. The sensing module collects odor, VOC, and carbon dioxide information in real time: odor is identified by an array of sensors, and VOC and carbon dioxide are measured by the corresponding gas sensors in the array. When an odor is detected, or either VOC or carbon dioxide exceeds a threshold (e.g., the carbon dioxide threshold range is [X1, X2] ppm, and the detection method is direct measurement by the carbon dioxide sensor), the sensing module sends a message to the domain controller, which then starts or adjusts the air conditioning blower to perform external air circulation. Different air quality levels correspond to different ventilation levels, which are matched and controlled through a preset mapping table.

[0089] In short-term parking mode, the vehicle is powered off, but the sensing module continues to operate for 2 hours. During this period, if an odor or VOC exceeding the threshold is detected (carbon dioxide is not detected), the controller activates the blower for ventilation, defaulting to the lowest setting for slow ventilation. If the odor or VOC does not improve after 10 minutes of continuous ventilation, the controller increases the blower speed by one level to enhance the ventilation effect.

[0090] In long-term parking mode, if the vehicle is powered off and not powered back on within 2 hours, the sensing module enters sleep mode to save energy. At this time, the sensing module can be woken up at preset daily, weekly, or monthly cycles, with each cycle lasting 2 hours. During wake-up, if an odor or VOC exceeding the threshold is detected (but carbon dioxide is not detected), the controller starts the blower for ventilation, using only the lowest setting for slow ventilation, and then enters sleep mode again after a period of continuous ventilation (e.g., 2 hours).

[0091] When the vehicle's battery level falls below a preset threshold, the sensing module stops working, and the automatic ventilation function is turned off.

[0092] Through the collaborative work of the aforementioned sensing module and ventilation module, and the ventilation control strategies formulated for different scenarios, this application constructs a complete "detection-judgment-control-execution" signal action chain, effectively solving the problems of inaccurate cabin ventilation adjustment and difficulty in balancing energy consumption and air quality monitoring in the prior art when the vehicle is parked.

[0093] This application employs an array of sensors for odor detection and combines this with machine learning algorithms for odor type identification, significantly improving the accuracy of odor recognition within the cabin. This allows for more precise determination of whether ventilation is needed and the intensity of ventilation. Ventilation control strategies tailored to different vehicle parking scenarios use odor characteristics as the trigger for automatic ventilation, ensuring that the control results directly correspond to the user's subjective perception. Simultaneously, ventilation is triggered when the VOC concentration exceeds a threshold, mitigating the potential health hazards of harmful gases to users.

[0094] In rest scenarios, since people still remain inside the vehicle, this application adds a check to determine whether the carbon dioxide concentration exceeds a threshold, in addition to the above-mentioned checks, to avoid adverse reactions such as decreased blood oxygen saturation due to excessively high CO2 concentration inside the vehicle. Simultaneously, based on multi-dimensional information such as odor type and its degree of discomfort, and gas concentration, different air quality levels are set, and ventilation strategies are adjusted accordingly to achieve a balance between energy consumption, occupant comfort, and ventilation efficiency, providing a healthier and more comfortable cabin environment for vehicle occupants.

[0095] In short-term parking mode, since no one is inside the vehicle, there is no need to perform carbon dioxide detection. However, considering that users may start the vehicle at any time, this application continues to monitor the air quality inside the vehicle and performs appropriate ventilation even after the vehicle is powered off to prevent the accumulation of odors and harmful gases. In long-term parking mode, the array sensor enters a sleep state and is periodically awakened, performing only the minimum level of basic ventilation, which reduces energy consumption and periodically checks and improves the air quality inside the vehicle. When the vehicle's battery is too low, the system prioritizes energy safety and disables the automatic ventilation function.

[0096] In practical implementation, this involves a cabin that can automatically ventilate based on passenger compartment odors while the vehicle is parked. This embodiment details the implementation process of such a cabin. The cabin mainly consists of a sensing module and a ventilation module; through their collaborative operation, the function of automatically ventilating based on passenger compartment odors is achieved.

[0097] In practical implementation, in order to achieve automatic ventilation, the control method is as follows: Figure 5 As shown, the specific steps include: Step S01: Obtain the vehicle parking signal; Step S02: Determine whether the vehicle power failure is detected; if not, proceed to step S03; if yes, proceed to step S04. Step S03: Perform ventilation control according to the first ventilation strategy, that is, select the rest mode function logic to control automatic ventilation. Step S04: Perform ventilation control according to the second ventilation strategy, that is, select the short-term parking mode to control automatic ventilation, and execute step S05. Step S05: Determine whether the vehicle power-off time exceeds t1; if yes, proceed to step S06; if no, proceed to step S04; t1 is preferably 2 hours. Step S06: Perform ventilation control according to the third ventilation strategy, that is, select the long-term parking mode to control automatic ventilation.

[0098] For specific implementation details, please refer to [link / reference]. Figure 6 The first ventilation strategy mentioned above specifically includes the following steps: Step S031: The array sensor operates to sense the air quality inside the cabin; Step S032: Determine the current air quality level inside the cabin; Step S033: Start or adjust the air conditioner and blower, and select the corresponding ventilation setting.

[0099] For specific implementation details, please refer to [link / reference]. Figure 7 The second ventilation strategy mentioned above specifically includes the following steps: Step S041: The array sensor operates to sense the air quality inside the cabin; Step S042: Determine if there is an odor or excessive VOC levels; if yes, proceed to step S043; otherwise, end. Step S043: Start the air conditioner and blower, and select the lowest ventilation setting to operate for a duration of t2; t2 is preferably 10 minutes. Step S044: Determine whether the current cabin air quality level has improved; if yes, proceed to step S045; if no, proceed to step S046. Step S045: Turn off the air conditioner and blower, and end.

[0100] Step S046: Adjust the air conditioner and blower, and select a higher ventilation setting for operation time t2.

[0101] For specific implementation details, please refer to [link / reference]. Figure 8 The third ventilation strategy mentioned above specifically includes the following steps: Step S061, the array sensor enters sleep mode; Step S062: Determine whether the hibernation time exceeds t3; if yes, proceed to step S063; if no, proceed to step S061; t3 is preferably 24 hours. Step S063: Wake up the array sensor to work and sense the air quality inside the cabin; Step S064: Determine whether the working time of the array sensor is less than the duration t4; if yes, proceed to step S065; if no, proceed to step S061; the duration t4 can be equal to or different from the duration t1. Step S065: Determine if there is an odor or excessive VOCs; if yes, proceed to step S066; if no, proceed to step S067. Step S066: Start the air conditioner blower and select the lowest ventilation setting; Step S067: Turn off the air conditioner and blower; Step S068: Determine whether a vehicle power-on signal is detected; if yes, end; if no, proceed to step S063.

[0102] When the battery level is below a threshold (e.g., 20%), the sensing module will not work, and the automatic ventilation function will be turned off.

[0103] Through the above technical solution, this application realizes automatic ventilation control of the passenger compartment when the vehicle is parked, effectively suppresses the accumulation of odors, and ensures the safety and controllability of the vehicle's energy consumption through a low-power control mechanism.
