Description

Technical Field

[0001] This application relates to the field of automotive air purification and filtration, and more particularly to a method, device, electronic equipment, and vehicle for controlling in-vehicle air purification. Background Technology

[0002] Currently, in the field of air quality monitoring and purification in automotive intelligent cockpits, mainstream technical solutions typically employ an "identity recognition-preset linkage" mechanism. Specifically, the system first monitors the air quality inside and outside the vehicle in real time using in-vehicle sensors (such as particulate matter sensors). When the concentration of specific particulate matter, such as pollen or PM2.5, exceeds a preset threshold, the system triggers response logic. The core of this logic is identifying the current passenger, for example, through facial recognition or account login information. Subsequently, the system retrieves a pre-set profile associated with that identity, containing the passenger's pre-registered allergen information (such as whether they are allergic to pollen). If the system determines that the allergens in the current environment match the passenger's pre-set allergy information, it automatically controls the air conditioning system to switch to recirculation mode and activates the air purification device to achieve targeted protection.

[0003] This technical solution has improved the level of personalization and intelligence to some extent. However, in practical applications, the solution has gradually revealed its inherent limitations, mainly in the following two aspects: 1. Passivity and Incompleteness of Protection Activation: The effectiveness of this solution relies entirely on the pre-established and complete information in the passenger's personal profile. If a new passenger is using the service for the first time, the passenger forgets or is unwilling to enter their personal health information (especially sensitive health information such as allergy history), or the pre-set information does not cover all possible allergens, the system will be unable to obtain crucial judgment criteria. In this situation, even if the sensors have detected a high concentration of allergens and the passenger has shown adverse reactions, the system will not activate the purification process, resulting in protection failure and the personalized service becoming meaningless.

[0004] 2. Rigid Judgment Logic and Potential Misjudgment: This scheme relies on static, binary pre-set information ("yes" or "no" allergic), ignoring the dynamic nature and individual differences in the human body's response to allergens. Different individuals have significantly different tolerance thresholds for the same allergen, and the sensitivity of the same person varies under different physical conditions. A pre-set "allergic" label may cause the system to activate purification even at low concentrations and when passengers are actually unaware, resulting in energy waste and overreaction; while a pre-set "not allergic" label may refuse to provide purification when passengers actually feel discomfort, failing to meet dynamically changing actual needs.

[0005] Therefore, a new method for controlling in-vehicle air purification is urgently needed to solve the above problems. Summary of the Invention

[0006] In view of this, this application provides a method, device, electronic device and storage medium for controlling in-vehicle air purification, which can actively and accurately identify and respond to passengers' allergies, thereby improving the passenger's riding experience.

[0007] A first aspect of this application provides a method for controlling in-vehicle air purification, comprising: detecting the concentration of allergens in the vehicle at first preset intervals; when the allergen concentration is detected to be greater than a preset concentration, turning on the vehicle's air purifier and acquiring image data corresponding to each passenger in the vehicle at second preset intervals, wherein the filter fan of the air purifier operates at a first rotation speed; performing image recognition on the image data and detecting, based on the image recognition result, whether there is a target passenger whose current behavior meets a preset allergic physiological behavior; when the target passenger is detected, turning on the vehicle's air conditioner and switching the air conditioner to recirculation mode; and controlling the filter fan to operate at a second rotation speed, wherein the second rotation speed is greater than the first rotation speed.

[0008] In one possible implementation, the vehicle includes multiple areas, each of which is provided with at least one air outlet of the air conditioner; before turning on the air conditioner of the vehicle and switching the air conditioner to recirculation mode, the method further includes: determining the target area where the target passenger is located in the multiple areas; turning on the air conditioner of the vehicle and switching the air conditioner to recirculation mode includes: opening the air conditioner vent of the target area and switching the air conditioner to recirculation mode.

[0009] In one possible implementation, after opening the air conditioning vent of the target area, the method further includes: increasing the airflow of the air conditioning vent to a preset airflow, and delivering air to the target area through the air conditioning vent.

[0010] In one possible implementation, the vehicle includes an instrument panel and a central control display screen; when the allergen concentration is detected to be greater than a preset concentration, the method further includes: controlling the instrument panel and / or the central control display screen to display a first prompt message, wherein the first prompt message is used to remind passengers that the allergen concentration in the vehicle is too high.

[0011] In one possible implementation, when the presence of the target passenger is detected, the method further includes: controlling the dashboard and / or the central control display to display a second prompt message, wherein the second prompt message is used to remind the passenger that the air purification function has been activated.

[0012] In one possible implementation, after controlling the filter fan to operate at a second speed, the method further includes: if the allergen concentration is detected to be less than or equal to the preset concentration and the target passenger is not detected again within a first preset time period, switching the air conditioner to an external circulation mode or a mixed circulation mode, and switching the air purifier to a standby state.

[0013] In one possible implementation, the step of detecting whether there is a target passenger whose current behavior meets the preset allergic physiological behavior based on the result of image recognition includes: detecting whether there is a target passenger whose continuous eye rubbing duration is greater than or equal to a third preset duration, or whose sneezing frequency is greater than or equal to a preset number within a preset time period, or whose facial expression is identified as a painful expression.

[0014] Secondly, embodiments of this application also provide a vehicle in-vehicle air purification control device, including: a detection module, a first control module, an acquisition module, an identification module, and a second control module; the detection module is used to detect the concentration of allergens in the vehicle every first preset time interval; the first control module is used to turn on the vehicle's air purifier when the detection module detects that the allergen concentration is greater than a preset concentration, wherein the filter fan of the air purifier operates at a first speed; the acquisition module is used to acquire image data corresponding to each passenger in the vehicle every second preset time interval; the identification module is used to perform image recognition on the image data and detect, based on the image recognition result, whether there is a target passenger whose current behavior meets a preset allergic physiological behavior; the second control module is used to turn on the vehicle's air conditioner and switch the air conditioner to an internal circulation mode when the identification module detects the presence of the target passenger; the first control module is also used to control the filter fan to operate at a second speed, wherein the second speed is greater than the first speed.

[0015] Thirdly, embodiments of this application also provide an electronic device, the electronic device including a processor and a memory, the memory being used to store instructions, and the processor being used to call the instructions in the memory, causing the electronic device to execute the vehicle in-flight air purification control method as described in the first aspect.

[0016] Fourthly, this application also provides a vehicle, including: a visual perception device, an in-vehicle environment monitoring device, and a vehicle control unit; the in-vehicle environment monitoring device detects the concentration of allergens in the vehicle every first preset time interval; when the in-vehicle environment monitoring device detects that the allergen concentration is greater than a preset concentration, the vehicle control unit turns on the vehicle's air purifier, wherein the air purifier's filter fan operates at a first speed; the visual perception device acquires image data corresponding to each passenger in the vehicle every second preset time interval; the vehicle control unit performs image recognition on the image data and detects whether there is a target passenger whose current behavior meets a preset allergic physiological behavior based on the image recognition result; when the vehicle control unit detects the presence of the target passenger, it turns on the vehicle's air conditioner and switches the air conditioner to internal circulation mode; the vehicle control unit controls the filter fan to operate at a second speed, wherein the second speed is greater than the first speed.

[0017] Compared with related technologies, the embodiments of this application have at least the following advantages: First, it achieves a leap from "relying on presets" to "real-time perception." The embodiments of this application do not require passengers to pre-enter any personal health and privacy information, solving the problem of blind spots in protection for new passengers, temporary passengers, or passengers unwilling to disclose health information, greatly expanding the applicable scenarios and user groups. Second, by combining objective allergen concentration with whether passengers exhibit allergic physiological behaviors, it can more accurately determine the authenticity and urgency of air purification needs. This avoids energy waste (false activation) caused by slightly high concentrations that passengers are unaware of, and also provides timely protection when passengers, although not preset to "allergic," actually feel discomfort (missed activation), achieving true demand-driven protection. Finally, it embodies the evolution of the intelligent cockpit from "environmental response" to "user state response." It shifts the cockpit's focus from simple environmental parameters to the state of the "person" themselves. By acquiring image data corresponding to each passenger in the vehicle, and based on the recognition results of the image data, it detects whether there are target passengers whose current behavior meets preset allergic physiological behaviors, thereby providing more predictive and caring proactive services and improving the passenger's riding experience.

[0018] The technical effects achieved by the second, third, and fourth aspects mentioned above are similar to those achieved by the corresponding technical means in the first aspect, and will not be repeated here. Attached Figure Description

[0027] OMS (Occupant Monitoring System) is a comprehensive monitoring platform in intelligent vehicles used to perceive, identify, and analyze the status of all occupants in real time. It mainly relies on multi-sensor fusion technology such as cameras, infrared sensors, and millimeter-wave radar, combined with computer vision and deep learning algorithms, to achieve functions such as passenger presence detection, headcount, posture recognition, emotion judgment, and even biometric verification.

[0028] Particulate matter sensor: An electronic device used to detect the concentration of suspended particulate matter in the air, widely used in air purifiers, fresh air systems, environmental monitoring stations and smart homes.

[0029] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the steps of an embodiment of the vehicle in-flight air purification control method provided in this application. Depending on different requirements, the order of steps in this flowchart can be changed, and some steps can be omitted.

[0030] It should be noted that the vehicle in-vehicle air purification control method of this application embodiment can be applied in vehicle driving scenarios, and its execution subject can be a vehicle in-vehicle air purification control device. For example, during vehicle driving, the air in the vehicle can be purified through the vehicle in-vehicle air purification control device. Of course, the vehicle in-vehicle air purification control method can also be applied to other scenarios that require air purification, and this application does not specifically limit it in this regard.

[0031] The specific process of this embodiment is as follows: Figure 1 As shown, it includes the following steps: S101, the concentration of allergens in the vehicle is detected every first preset time interval.

[0032] In some embodiments, the first preset duration is not specifically limited and can be set according to actual needs. For example, the first preset duration can be set to 0, 1 s, 10 s, etc. When the first preset duration is 0, the concentration of allergens in the vehicle is detected in real time.

[0033] In some embodiments, the concentration of allergens inside the vehicle is detected by a particulate sensor.

[0034] In some embodiments, allergens include, but are not limited to, pollen, PM2.5, etc.

[0035] S102, when the concentration of allergens detected is greater than the preset concentration, the vehicle's air purifier is turned on, wherein the air purifier's filter fan runs at the first speed.

[0036] In some embodiments, the preset concentration is not specifically limited and can be set according to actual needs.

[0037] In some embodiments, the air purifier's filter fan operates at a first speed, meaning the air purifier maintains low-speed operation to keep basic airflow and does not activate the high-efficiency purification mode.

[0038] In some embodiments, the vehicle includes a cabin atmosphere system that remains unchanged and without light or sound alerts when an allergen concentration is detected to be greater than a preset concentration, so as to avoid disturbing passengers.

[0039] In some embodiments, the vehicle includes an instrument panel and a central control display screen. When an allergen concentration is detected to be higher than a preset concentration, the method further includes: controlling the instrument panel and / or the central control display screen to display a first alert message, wherein the first alert message is used to remind passengers that the allergen concentration inside the vehicle is high. For example, the first alert message could be "Rainy pollen concentration detected, passenger status being monitored," to avoid directly activating the air purifier and causing confusion for passengers.

[0040] In some embodiments, when the concentration of allergens detected is greater than a preset concentration, the air conditioning in the vehicle maintains its current operating mode, but the damper actuator enters a low-power standby state to ensure a rapid response.

[0041] S103, every second preset time interval, acquire image data corresponding to each passenger in the vehicle.

[0042] In some embodiments, the size of the second preset duration is not specifically limited and can be set according to actual needs. For example, the second preset duration can be set to 0, 1 second, 10 seconds, etc. When the second preset duration is 0, image data corresponding to each passenger in the vehicle is acquired in real time.

[0043] In some embodiments, the vehicle is equipped with an OMS vision system to acquire image data.

[0044] S104, perform image recognition on the image data, and detect whether there are target passengers whose current behavior meets the preset allergic physiological behavior based on the image recognition results.

[0045] In some embodiments, detecting whether there are target passengers whose current behavior meets preset allergic physiological behaviors based on the results of image recognition includes: detecting whether there are target passengers who continuously rub their eyes for a duration greater than or equal to a third preset duration, or who sneeze more than or equal to a preset number of times within a preset time period, or whose facial expressions are identified as painful expressions.

[0046] For example, detecting whether a passenger rubs their eyes continuously for more than 10 seconds, or sneezes ≥3 times within 30 seconds. This embodiment does not specifically limit the third preset duration, preset time period, or preset number of times; these can be set according to actual needs.

[0047] It's worth noting that if allergen information is provided by passengers, the specific allergen concentration can be difficult to determine due to individual differences in allergen tolerance. This could lead to situations where the air purifier is activated even when the allergen concentration is low, or the concentration is high but hasn't reached the passenger's set threshold, thus not activating the air purifier. Therefore, this embodiment assesses the passenger's actual cabin experience by monitoring actual allergic reactions such as sneezing, rubbing eyes, and blowing the nose, achieving a higher level of passenger health and wellness care.

[0048] S105, upon detecting the presence of a target passenger, turns on the vehicle's air conditioning and switches it to recirculation mode.

[0049] In some embodiments, the vehicle includes multiple areas, each area having at least one air vent for an air conditioner; before turning on the vehicle's air conditioner and switching it to recirculation mode, the method further includes: determining the target area where the target passenger is located in the multiple areas; turning on the vehicle's air conditioner and switching it to recirculation mode includes: opening the air vent of the target area and switching the air conditioner to recirculation mode.

[0050] In some embodiments, after opening the air conditioning vents in the target area, the method further includes: increasing the airflow of the air conditioning vents to a preset airflow, and delivering air to the target area through the air conditioning vents.

[0051] In some embodiments, when the presence of the target passenger is detected, the method further includes: controlling the dashboard and / or the central control display to display a second prompt message, wherein the first prompt message is used to remind the passenger that the air purification function has been activated. For example, the second prompt message may be "Allergic reaction detected, air purification activated," and may be accompanied by a soft voice prompt.

[0052] S106 controls the filter element fan to operate at a second speed, wherein the second speed is greater than the first speed.

[0053] In some embodiments, controlling the filter fan to operate at a second speed, i.e., the air purifier starts a high-efficiency purification mode, includes: activating the high-speed fan of the HEPA filter and starting the negative ion / plasma generator.

[0054] In some embodiments, soft flashing lights (such as a light green breathing light on an air conditioner panel) can be used to indicate that purification has been activated.

[0055] Compared with related technologies, the embodiments of this application have at least the following advantages: First, it achieves a leap from "relying on presets" to "real-time perception." The embodiments of this application do not require passengers to pre-enter any personal health and privacy information, solving the protection blind spot problem for new passengers, temporary passengers, or passengers unwilling to disclose health information, greatly expanding the applicable scenarios and user groups. Second, by combining objective allergen concentration with whether passengers exhibit allergic physiological behaviors, the authenticity and urgency of air purification needs can be more accurately determined. This avoids energy waste (false activation) caused by slightly high concentrations that passengers are unaware of, and also provides timely protection when passengers feel discomfort even though they haven't preset "allergies" (missed activation). This cross-validation mechanism greatly improves the accuracy of judgment, reducing false activation caused by high concentrations that people are unaware of, and providing protection when the concentration has not reached the preset threshold but people are already uncomfortable, achieving true demand-driven operation. Finally, it reflects the evolution of intelligent cockpits from "environmental response" to "user status response." The focus of the cabin shifts from simple environmental parameters to the state of the "people" themselves. By acquiring image data of each passenger in the vehicle and identifying whether there are target passengers whose current behavior meets the preset allergic physiological behaviors, the system can provide more proactive and caring services, thus improving the passenger's travel experience.

[0056] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating the steps of an embodiment of the vehicle in-flight air purification control method of this application. Depending on different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted. This vehicle in-flight air purification control method can be applied to the aforementioned vehicle in-flight air purification control device, but is not limited thereto, and the embodiments of this application do not limit it in this regard.

[0057] This embodiment is a further improvement on the aforementioned embodiment. The main improvement is that, in this embodiment, after controlling the filter fan to run at the second speed, if the allergen concentration is detected to be less than or equal to a preset concentration and no target passenger is detected again within a first preset time period, the air conditioner is switched to external circulation mode or mixed circulation mode, and the air purifier is switched to standby mode. In this way, energy consumption during driving can be reduced while ensuring the health of passengers.

[0058] The specific process of this embodiment is as follows: Figure 2 As shown, it includes the following steps: S201, the concentration of allergens in the vehicle is detected every first preset time interval.

[0059] S202, when the concentration of allergens detected is greater than the preset concentration, the vehicle's air purifier is turned on, wherein the air purifier's filter fan runs at the first speed.

[0060] S203, every second preset time interval, acquire image data corresponding to each passenger in the vehicle.

[0061] S204, perform image recognition on the image data, and detect whether there are target passengers whose current behavior meets the preset allergic physiological behavior based on the image recognition results.

[0062] S205, upon detecting the presence of a target passenger, turns on the vehicle's air conditioning and switches it to recirculation mode.

[0063] S206 controls the filter element fan to operate at a second speed, wherein the second speed is greater than the first speed.

[0064] S201 to S206 in this embodiment are similar to S101 to S106 in the previous embodiment. To avoid repetition, they will not be described again here.

[0065] S207: If the concentration of allergen detected is less than or equal to the preset concentration and no target passenger is detected again within the first preset time period, the air conditioner is switched to external circulation mode or mixed circulation mode, and the air purifier is switched to standby mode.

[0066] In some embodiments, the length of the first preset time period is not specifically limited and can be set according to actual needs. For example, it can be set to 1 minute, 3 minutes, etc.

[0067] In some embodiments, if the concentration of allergens continues to rise or the target passenger's allergic behavior recurs, the system can determine that it is "severe pollution or the passenger is highly sensitive" and record the event to the passenger's temporary file for pre-response in similar environments in the future.

[0068] In some embodiments, the central control screen displays a "Air purification complete" message and saves a summary of the event in the history.

[0069] Compared with related technologies, the embodiments of this application have at least the following advantages: First, it achieves a leap from "relying on presets" to "real-time perception." The embodiments of this application do not require passengers to pre-enter any personal health and privacy information, solving the protection blind spot problem for new passengers, temporary passengers, or passengers unwilling to disclose health information, greatly expanding the applicable scenarios and user groups. Second, by combining objective allergen concentration with whether passengers exhibit allergic physiological behaviors, the authenticity and urgency of air purification needs can be more accurately determined. This avoids energy waste (false activation) caused by slightly high concentrations that passengers are unaware of, and also provides timely protection when passengers feel discomfort even though they haven't preset "allergies" (missed activation). This cross-validation mechanism greatly improves the accuracy of judgment, reducing false activation caused by high concentrations that people are unaware of, and providing protection when the concentration has not reached the preset threshold but people are already uncomfortable, achieving true demand-driven operation. Finally, it reflects the evolution of intelligent cockpits from "environmental response" to "user status response." The focus of the cabin shifts from simple environmental parameters to the state of the "people" themselves. By acquiring image data of each passenger in the vehicle and identifying whether there are target passengers whose current behavior meets the preset allergic physiological behaviors, the system can provide more proactive and caring services, thus improving the passenger's travel experience.

[0080] In one embodiment, when the processor 401 executes the in-vehicle air purification control program in the memory 402, the following steps can be implemented: The concentration of allergens inside the vehicle is detected every first preset time interval; If the concentration of the allergen is detected to be greater than a preset concentration, the air purifier of the vehicle is turned on, and image data corresponding to each passenger in the vehicle is acquired every second preset time interval, wherein the filter fan of the air purifier is running at a first speed.
