[0026] To enable those skilled in the art to utilize the content of this application, and in conjunction with the specific application scenario of "intelligent cockpit health management technology," the following embodiments are provided. For those skilled in the art, the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application. Although this application is primarily described within the "intelligent cockpit health management technology field," it should be understood that this is merely an exemplary embodiment.

[0027] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0028] The following is a detailed description of an in-vehicle oxygen supply method provided by an embodiment of this application.

[0029] Reference Figure 1 The diagram shown is a flowchart illustrating an in-vehicle oxygen supply method according to an embodiment of this application. The exemplary steps of this embodiment are described below: S101. Collect the first monitoring data corresponding to the first preset monitoring dimension and the second monitoring data corresponding to the second preset monitoring dimension from the vehicle.

[0030] In this application embodiment, the first preset monitoring dimension is used to determine whether the vehicle's occupants are hypoxic due to their own physiological state; the second preset monitoring dimension is used to determine whether the occupants are hypoxic due to factors in the vehicle's internal and external environment.

[0031] For example, the first preset monitoring dimension may include the driver's blood oxygen saturation (SpO2), heart rate (HR), respiratory rate (RR), heart rate variability (HRV), and mental stress index (predicted based on heart rate variability, which can be achieved by training an AI model). In addition to the above dimensions, the first preset monitoring dimension may also include the magnitude and duration of the decrease in the driver's blood oxygen saturation relative to the driver's historical blood oxygen saturation baseline, the type of heart rate change trend (abnormal increase trend, abnormal decrease trend, etc.), the degree of decrease in heart rate variability (indicating stress or fatigue), the degree of respiratory rate disorder, and behavioral characteristics highly correlated with physiological hypoxia (fatigue synergistic characteristics: the percentage of pupil obstruction by eyelids per unit time, PERCLOS value (eye opening and closing degree), and micro-behaviors such as yawning frequency, gaze direction, and nodding movements, accompanied by a slow decrease in blood oxygen saturation and a decrease in HRV; sudden discomfort characteristics: the strong temporal correlation between abnormal behaviors such as frequent chest clutching and physiological signals such as rapid heart rate fluctuations and shortness of breath).

[0032] For example, the second preset monitoring dimension may include the oxygen (O2) concentration in the vehicle cabin environment, the slope and acceleration of the decrease in oxygen concentration (which can determine whether the hypoxia is gradual or sudden), the altitude of the vehicle (to construct a comprehensive environmental criterion. For example, in high-altitude areas, even if the percentage of O2 concentration in the vehicle remains unchanged, its actual partial pressure has decreased, constituting "equivalent environmental hypoxia"), carbon dioxide (CO2) concentration, etc.

[0033] For example, vehicle environmental data, driver and passenger physiological data, driver and passenger fatigue and distraction data are collected through the perception layer; the data collected by the perception layer is preprocessed; and the first monitoring data corresponding to the first preset monitoring dimension and the second monitoring data corresponding to the second preset monitoring dimension are extracted from the preprocessed data.

[0034] For example, 1. Sensing layer acquisition: (1) Vehicle environment data: O2 concentration sensor; altitude. (2) Physiological data of drivers and passengers: Based on non-contact rPPG (remote photoplethysmography) technology, through the facial RGB camera facing the driver and passengers, in a mode that fully protects privacy, the key parameters such as blood oxygen saturation, heart rate (HR), respiratory rate (RR), and heart rate variability (HRV) are analyzed and output in real time. (3) Fatigue and distraction: Based on the independent driver and passenger monitoring DMS camera, the micro-behaviors such as eye opening and closing, gaze direction, yawning frequency, and nodding are continuously monitored to accurately identify the fatigue and distraction state score. 2. Data preprocessing: (1) Data alignment and synchronization: In order to eliminate the timestamp difference between different sensors, all accessed time-series data are time-aligned with a unified clock source to ensure the global synchronization of data points. (2) Noise filtering and signal enhancement: a. Bandpass filtering and motion artifact compensation algorithms are applied to physiological signals to effectively suppress noise interference introduced by vehicle vibration and driver body shaking, and to extract clean physiological cycle signals. b. Apply a moving average filter to environmental sensor data to smooth out instantaneous fluctuations and more accurately reflect trend changes. Invalid data removal: Monitor the data quality of each sensor in real time. When a camera is obstructed, the signal is lost, or the data significantly exceeds a reasonable range, the data for that period will be marked as invalid and excluded from the current analysis cycle.

[0035] S102. Determine the physiological hypoxia assessment result of the driver and passengers based on the first monitoring data; and determine the environmental hypoxia assessment result of the driver and passengers based on the second monitoring data.

[0036] In this application embodiment, two methods are provided to determine the physiological hypoxia assessment result of the driver and passengers based on first monitoring data. Two methods are also provided to determine the environmental hypoxia assessment result of the driver and passengers based on second monitoring data.

[0037] Specifically, the first determination method involves: determining the physiological hypoxia assessment result of the driver and passengers based on the first monitoring data, including: inputting the first monitoring data into the physiological hypoxia assessment model to obtain the physiological hypoxia assessment result of the driver and passengers. The second determination method involves: determining the environmental hypoxia assessment result of the driver and passengers based on the second monitoring data, including: inputting the second monitoring data into the environmental hypoxia assessment model to obtain the environmental hypoxia assessment result of the driver and passengers.

[0038] In this embodiment, the physiological hypoxia determination model is an AI model pre-trained based on first monitoring sample data corresponding to a first preset monitoring dimension and physiological hypoxia determination labels corresponding to the first monitoring sample data. The environmental hypoxia determination model is an AI model pre-trained based on second monitoring sample data corresponding to a second preset monitoring dimension and environmental hypoxia determination labels corresponding to the second monitoring sample data. Physiological hypoxia determination results include both physiological hypoxia and non-physiological hypoxia. Environmental hypoxia determination results include both environmental hypoxia and non-environmental hypoxia.

[0039] The result of physiological hypoxia assessment indicates that the hypoxia is caused by the driver's own physiological state. The result of environmental hypoxia assessment indicates that the hypoxia is caused by environmental factors both inside and outside the vehicle.

[0040] Specifically, the second method for determining the physiological hypoxia assessment result is as follows: the physiological hypoxia assessment result of the driver and passenger is determined based on the first monitoring data, including: substituting the first monitoring data into the following formula to obtain the physiological hypoxia index value of the driver and passenger; if the physiological hypoxia index value of the driver and passenger is greater than the preset physiological hypoxia index threshold, then the physiological hypoxia assessment result of the driver and passenger is physiological hypoxia; otherwise, the physiological hypoxia assessment result of the driver and passenger is non-physiological hypoxia.

[0041] (1); (2); (3); (4); (5); in, The blood oxygen saturation of the drivers and passengers in the first monitoring data. This represents the hypoxia index value under blood oxygen saturation. The heart rate of the driver and passengers in the first monitoring data. This represents the hypoxia index value at heart rate. The respiratory rate of the driver and passengers in the first monitoring data. The value represents the hypoxia index at the respiratory rate. The heart rate variability of drivers and passengers in the first monitoring data. The value represents the hypoxia index under heart rate variability. These are physiological hypoxia index values. The weight of the i-th hypoxia index value. The fatigue distraction rate in the first monitoring data (the probability of fatigue distraction output by an AI model, ranging from [0,1], which can be determined by behavioral characteristics that are highly correlated with physiological hypoxia).

[0042] Regarding formula (1): The blood oxygen saturation of a normal adult is usually above 95%, and below 90% indicates hypoxia. When blood oxygen saturation is 95% or above, the corresponding risk value is no greater than 0. In order to linearly map the risk of hypoxia to between 0 and 1, 70% is set as the extremely low critical point (extreme hypoxia is below 70%), and 95-70=25 is used as the denominator. Regarding formula (2): The resting heart rate of a normal adult is roughly between 50-90 bpm. Both excessively high and low heart rates may reflect physiological abnormalities or compensatory pressure. HR>90 indicates compensatory tachycardia, and the risk of hypoxia increases linearly with increasing heart rate. 50 is the upper limit of the maximum risk heart rate. HR<50 indicates bradycardia, and the risk of hypoxia increases with decreasing heart rate. 40 is the lower limit of the maximum risk heart rate for hypoxia. 50-90 is considered normal, and the risk value of hypoxia is 0. Regarding formula (3): The respiratory rate (RR) of a normal adult is generally 12-20 breaths / minute. Breathing too fast or too slow may indicate respiratory or metabolic abnormalities. When the RR exceeds 20, the risk of hypoxia increases linearly with the respiratory rate. The risk of hypoxia is highest above 30. Therefore, when RR>20, the denominator is 10. The RR in the low respiratory risk range is <12 breaths / minute. However, under extreme hypoxia risk, RR can decrease to close to 4 breaths / minute or lower. Therefore, the range length can be selected as 12-4=8, and RR is linearly mapped from 12 to 4. The hypoxia risk is taken as 1 (maximum) when it is below 4 breaths / minute. Regarding formula (4): The HRV (referring to RMSSD) of a normal adult is generally greater than 30-50ms. Low HRV indicates high stress, sympathetic activation, fatigue, or hypoxia. The hypoxia risk is 0 when HRV>=50ms and close to 1 when HRF<=10ms (extremely low). The linear mapping converts HRV10~50ms into a hypoxia risk of 0~1. Regarding formula (5): Specifically, the second method for determining the environmental hypoxia determination result is as follows: determining the environmental hypoxia determination result of the driver and passengers based on the second monitoring data includes: substituting the second monitoring data into the following formula to obtain the environmental hypoxia determination result of the driver and passengers.

[0043] ; ; ; in, This represents the theoretical oxygen concentration after altitude correction for the vehicle's surrounding environment. This refers to the altitude of the environment where the vehicle is located, as shown in the second monitoring data. altitude Atmospheric pressure, Standard atmospheric pressure The results of assessing the oxygen deficiency in the environment for drivers and passengers. This refers to the oxygen concentration inside the vehicle in the second monitoring data. =1 indicates that the environmental oxygen deficiency assessment result for drivers and passengers is that the environment is oxygen-deficient. =0 indicates that the environmental hypoxia assessment result for drivers and passengers is not environmental hypoxia. This represents the oxygen volume fraction at sea level. . To set a safe threshold, a value of 0.92 to 0.95 is recommended (a value 5-8% below the normal level is considered a possible sign of hypoxia).

[0044] S103. Based on the results of physiological hypoxia assessment and environmental hypoxia assessment, determine the target oxygen supply mode from the preset oxygen supply modes.

[0045] Specifically, if the physiological hypoxia determination result is physiological hypoxia and the environmental hypoxia determination result is non-environmental hypoxia, then the centralized oxygen supply mode in the preset oxygen supply mode is determined as the target oxygen supply mode; the centralized oxygen supply mode is used to provide targeted oxygen supply for drivers and passengers.

[0046] In the embodiments of this application, the core of the centralized oxygen supply mode is "targeted and precise replenishment", which is specifically designed to meet the individual physiological hypoxia needs of drivers and passengers (referring to drivers and other passengers). Oxygen is precisely delivered to drivers and passengers through centralized oxygen supply pipelines in the seating area of ​​the drivers and passengers, avoiding oxygen diffusion and waste.

[0047] Specifically, if the physiological hypoxia determination result is non-physiological hypoxia and the environmental hypoxia determination result is environmental hypoxia, then the balanced oxygen supply mode in the preset oxygen supply mode is determined as the target oxygen supply mode; the balanced oxygen supply mode is used to uniformly increase the overall environmental oxygen concentration inside the vehicle.

[0048] In the embodiments of this application, the core of the balanced oxygen supply mode is "uniform oxygen replenishment throughout the entire cabin", which is specifically designed for scenarios where the oxygen concentration in the vehicle environment is insufficient. By activating the balanced oxygen supply pipeline in the cabin, oxygen is evenly diffused throughout the entire cabin area.

[0049] Specifically, if the physiological hypoxia determination result is physiological hypoxia and the environmental hypoxia determination result is environmental hypoxia, then the mixed oxygen supply mode in the preset oxygen supply mode is determined as the target oxygen supply mode; the mixed oxygen supply mode is used to provide directional oxygen supply to drivers and passengers while uniformly increasing the overall environmental oxygen concentration inside the vehicle.

[0050] S104. Issue control commands to the oxygen supply equipment on the vehicle according to the target oxygen supply mode in order to supply oxygen to the driver and passengers.

[0051] Reference Figure 2 The diagram shown is a flowchart of another in-vehicle oxygen supply method provided in this application embodiment. The implementation process of issuing control commands to the oxygen supply equipment installed in the vehicle according to the target oxygen supply mode to supply oxygen to the driver and passengers is as follows: S201. Real-time collection of oxygen concentration monitoring data in the area of ​​the vehicle corresponding to the target oxygen supply mode.

[0052] In this embodiment, if the target oxygen supply mode is a centralized oxygen supply mode, oxygen concentration monitoring data of the vehicle and the breathing area of ​​the driver and passengers are collected in real time. If the target oxygen supply mode is a balanced oxygen supply mode, oxygen concentration monitoring data of the entire cabin area of ​​the vehicle is collected in real time. If the target oxygen supply mode is a mixed oxygen supply mode, oxygen concentration monitoring data of the vehicle and the breathing area of ​​the driver and passengers, as well as oxygen concentration monitoring data of the entire cabin area of ​​the vehicle, are collected in real time.

[0053] The breathing zone for occupants refers to the core space near the head of the occupant (primarily the driver) where they can directly inhale air; this is the precise target area for oxygen delivery. Oxygen concentration monitoring data across the entire vehicle cabin refers to oxygen concentration data covering the entire cabin space (including the front driver's seat, front passenger seat, and rear passenger area). Its core function is to reflect the overall distribution and average level of oxygen concentration in all areas of the cabin.

[0054] S202. Based on oxygen concentration monitoring data, determine the oxygen supply parameters of the target oxygen supply equipment corresponding to the target oxygen supply mode.

[0055] Specifically, if the target oxygen supply mode is a centralized oxygen supply mode, then the first oxygen production rate and the first wind force in the oxygen supply parameters are determined based on the oxygen concentration monitoring data.

[0056] In the embodiments of this application, a proportional-integral-derivative (PID) algorithm can be used to determine the first oxygen production rate and the first wind force in the oxygen supply parameters based on oxygen concentration monitoring data, so as to ensure that the oxygen concentration in the breathing area of ​​the driver and passengers is within the preset normal oxygen concentration range.

[0057] Specifically, if the target oxygen supply mode is a balanced oxygen supply mode, then the second oxygen production speed and the second wind force in the oxygen supply parameters are determined based on the oxygen concentration monitoring data.

[0058] In the embodiments of this application, a proportional-integral-derivative (PID) algorithm can be used to determine the second oxygen production rate and the second wind force in the oxygen supply parameters based on oxygen concentration monitoring data, so as to ensure that the oxygen concentration in the breathing area of ​​the driver and passengers is within the preset normal oxygen concentration range.

[0059] Specifically, if the target oxygen supply mode is a mixed oxygen supply mode, then based on the oxygen concentration monitoring data, the third oxygen production rate, the centralized oxygen supply ratio, the balanced oxygen supply ratio, the third wind force, and the fourth wind force in the oxygen supply parameters are determined, or the fourth oxygen production rate, the fifth wind force, and the sixth wind force in the oxygen supply parameters.

[0060] In this embodiment of the application, a proportional-integral-derivative (PID) algorithm can be used to determine the third oxygen production rate, centralized oxygen supply ratio, balanced oxygen supply ratio, third wind force, and fourth wind force in the oxygen supply parameters based on oxygen concentration monitoring data, or the third oxygen production rate, fifth wind force, and sixth wind force in the oxygen supply parameters, so as to ensure that the oxygen concentration in the breathing area of ​​the driver and passengers is within the preset normal oxygen concentration range.

[0061] S203. Issue control commands to the target oxygen supply equipment according to the oxygen supply parameters to supply oxygen to the drivers and passengers.

[0062] Specifically, if the target oxygen supply mode is a centralized oxygen supply mode, the step of issuing control commands to the target oxygen supply equipment according to the oxygen supply parameters to supply oxygen to the drivers and passengers includes: Step 1: Send the corresponding control command to the oxygen generator according to the first oxygen production rate in the oxygen supply parameters, so that the oxygen generator can produce oxygen based on the first oxygen production rate.

[0063] In this embodiment, the unit of the first oxygen production rate is L / min (liters per minute). An oxygen generator is a device used to generate oxygen.

[0064] Step 2: Issue an opening command to the centralized oxygen supply pipeline and a closing command to the balanced oxygen supply pipeline, so that the oxygen output from the oxygen generator is delivered to the first blowing device in the vehicle through the centralized oxygen supply pipeline.

[0065] In this embodiment of the application, the centralized oxygen supply pipeline is used to provide directional oxygen supply to drivers and passengers, that is, to deliver oxygen to the breathing area where the drivers and passengers are located.

[0066] Step 3: Based on the first wind force in the oxygen supply parameters, issue the corresponding control command to the first blowing device, so that the first blowing device blows oxygen to the driver and passengers according to the first wind force.

[0067] In this embodiment, the first air-blowing device includes a miniature DC booster pump and a constricting nozzle. Oxygen is pressurized by the miniature DC booster pump and then blown into the mouth and nose of the driver or passenger through the constricting nozzle to form a high-velocity jet.

[0068] Here, in the vehicle, each centralized oxygen supply pipeline corresponds to a first air blowing device, and each seat occupied by a driver or passenger corresponds to a corresponding air blowing device. The oxygen generator is connected to each first air blowing device via a corresponding centralized oxygen supply pipeline. For example, the outlet of the first air blowing device in the driver's breathing area can be a directional air outlet from the rearview mirror base.

[0069] Specifically, if the target oxygen supply mode is a balanced oxygen supply mode, the step of issuing control commands to the target oxygen supply device according to the oxygen supply parameters to supply oxygen to the drivers and passengers includes: Step 1: Send a corresponding control command to the oxygen generator according to the second oxygen production speed in the oxygen supply parameters, so that the oxygen generator produces oxygen based on the second oxygen production speed; Step 2: Send an opening command to the balanced oxygen supply pipeline and a closing command to the centralized oxygen supply pipeline, so that the oxygen output by the oxygen generator is delivered to the second blowing device in the vehicle through the balanced oxygen supply pipeline.

The second air blowing device can be an air conditioner, which, with the help of the air conditioning's air delivery capacity, rapidly and evenly dilutes and delivers oxygen-rich air into the cabin, quickly achieving a higher oxygen concentration so that the ambient oxygen deficiency index returns to normal. The balanced oxygen supply duct is used to uniformly increase the overall ambient oxygen concentration inside the vehicle.

[0071] Step 3: Based on the second wind force in the oxygen supply parameters, issue a corresponding control command to the second blowing device, so that the second blowing device blows oxygen to the driver and passengers according to the second wind force.

[0072] Here, the oxygen generator is connected to the second air blowing device through a balanced oxygen supply pipeline.

[0073] Specifically, if the target oxygen supply mode is a mixed oxygen supply mode, the step of issuing control commands to the target oxygen supply device according to the oxygen supply parameters to supply oxygen to the occupants includes: Step 1: Send a corresponding control command to the oxygen generator according to the third oxygen production speed in the oxygen supply parameters, so that the oxygen generator can produce oxygen based on the third oxygen production speed.

[0074] Step 2: Based on the centralized oxygen supply ratio and the balanced oxygen supply ratio, issue an activation command to the centralized oxygen supply pipeline and the balanced oxygen supply pipeline, so that the centralized oxygen supply pipeline delivers the oxygen output from the oxygen generator to the first air blowing device in the vehicle according to the centralized oxygen supply ratio; the balanced oxygen supply pipeline delivers the oxygen output from the oxygen generator to the second air blowing device in the vehicle according to the balanced oxygen supply ratio; the balanced oxygen supply pipeline is used to uniformly increase the overall oxygen concentration in the vehicle.

[0075] In this embodiment of the application, valves are installed in the centralized oxygen supply pipeline and the balanced oxygen supply pipeline, and the centralized oxygen supply ratio and the balanced oxygen supply ratio can be adjusted by adjusting the valves.

[0076] Step 3: Based on the third wind force in the oxygen supply parameters, a corresponding control command is issued to the first blowing device, so that the first blowing device blows oxygen to the driver and passengers according to the third wind force; based on the fourth wind force in the oxygen supply parameters, a corresponding control command is issued to the second blowing device, so that the second blowing device blows oxygen to the driver and passengers according to the fourth wind force.

[0077] Specifically, if the target oxygen supply mode is a mixed oxygen supply mode, the step of issuing control commands to the target oxygen supply device according to the oxygen supply parameters to supply oxygen to the drivers and passengers also includes: Step 1: Send a corresponding control command to the oxygen generator according to the fourth oxygen production speed in the oxygen supply parameters, so that the oxygen generator can produce oxygen based on the fourth oxygen production speed. Step 2: Issue an activation command to the centralized oxygen supply pipeline and the balanced oxygen supply pipeline, so that the centralized oxygen supply pipeline delivers the oxygen output from the oxygen generator to the first air blowing device in the vehicle; and the balanced oxygen supply pipeline delivers the oxygen output from the oxygen generator to the second air blowing device in the vehicle.

[0078] Step 3: Based on the fifth wind force in the oxygen supply parameters, a corresponding control command is issued to the first air blowing device, causing the first air blowing device to deliver oxygen to the driver and passengers according to the fifth wind force; based on the sixth wind force in the oxygen supply parameters, a corresponding control command is issued to the second air blowing device, causing the second air blowing device to maximize the air exchange rate in the vehicle cabin according to the sixth wind force, quickly and evenly distributing the abundant oxygen in the cabin, so that other occupants can absorb abundant oxygen as soon as possible.
