[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and examples.

[0041] Nowadays, the automobile has gone beyond a means of transportation and become a mobile living space, and needs to adapt to different driving environments and provide solutions to problems faced in various driving environments, for example, in a plateau environment, there is a systematic technical gap in the in-vehicle environment regulation, especially when the altitude exceeds 3000 meters, the oxygen content of the thin air drops sharply, and the headache, nausea and dizziness caused by the plateau reaction directly affect the judgment and reaction speed of the driver and the physiological health of the passengers, and by configuring an oxygen supply function for the vehicle, oxygen supply guarantee can be provided for the user in an emergency.

[0042] The present application provides a vehicle oxygen supply method, which can be applied to a vehicle oxygen supply system as shown in the accompanying drawings. Figure 1 The vehicle oxygen supply system comprises an oxygen supply source, for example, an oxygen generator, which exemplarily generates oxygen by the principle of molecular sieve pressure swing adsorption, adopts zeolite molecular sieve as an adsorbent, and preferentially adsorbs nitrogen gas and allows oxygen to pass through the microporous structure, thereby realizing oxygen-nitrogen separation, and through periodic pressure changes (high-pressure adsorption of nitrogen gas→low-pressure desorption regeneration), alternating work is ensured to ensure continuous oxygen supply.

[0043] The oxygen supply source is also, for example, an oxygen storage device such as an oxygen cylinder obtained by pressurizing oxygen.

[0044] The vehicle oxygen supply system further comprises an oxygen distribution unit and oxygen release units arranged at different positions, and the oxygen distribution unit is exemplarily a multi-way valve, which switches the path and the release amount of the oxygen release by controlling the structure of the valve.

[0045] The oxygen release unit is used for guiding the oxygen to the corresponding position for release, and in the present application, the oxygen release unit comprises a seat headrest diffusion assembly, an air conditioner air outlet assembly and a nasal catheter assembly.

[0046] The seat headrest diffusion assembly is arranged inside the seat headrest of the driver seat and / or the passenger seat, exemplarily releases oxygen to the driver through a plurality of diffusion outlets formed on the seat headrest, is suitable for light or no-sense oxygen supply; the air conditioner air outlet assembly is connected with the air conditioner air outlet based on the existing air conditioner air outlet components through an oxygen supply pipeline, can release oxygen to various spaces in the vehicle, improves the overall oxygen environment in the vehicle, and is suitable for large amount of oxygen supply; the nasal catheter assembly comprises a nasal plug, the nasal plug is connected with the oxygen release unit through an oxygen supply pipeline, the nasal catheter assembly is exemplarily arranged at the front and rear seat positions, is convenient for the user to use, and is suitable for concentrated oxygen supply for individuals.

[0047] In one embodiment of the present application, the vehicle oxygen supply method is as shown in the accompanying drawings. Figure 2As shown, comprising the following steps:

[0048] Step 110, obtaining the altitude and blood oxygen saturation.

[0049] The altitude of the location where the vehicle is located can be obtained in various ways. For example, based on the physical law that atmospheric pressure decreases with altitude, the real-time air pressure is measured by a high-precision air pressure sensor, and the altitude is obtained by converting the air pressure to altitude according to the air pressure to altitude formula.

[0050] For blood oxygen saturation, a feasible way is to use a finger clip type blood oxygen meter or other equipment, but it needs to be actively performed by a person. In this embodiment, near-infrared spectroscopy can be used for non-invasive detection. For example, an oxygen saturation probe is arranged at the position of the steering wheel, and 940nm+660nm dual-band spectrum is used to detect the change of light absorption ratio during arterial pulsation and convert it into blood oxygen saturation. To compensate for the accuracy of data collected by the steering wheel, PPG (Photoplethysmography) technology can be used to correct the data.

[0051] Step 120, determining the oxygen demand index according to the altitude and blood oxygen saturation.

[0052] The oxygen demand index is used to reflect the demand for oxygen supply under the current environment (altitude) and the user's own state (blood oxygen saturation).

[0053] The oxygen demand index is positively correlated with the altitude. When the altitude is higher, the oxygen in the air is thinner, and at this time the demand for oxygen supply is higher to avoid hypoxia of the user.

[0054] The oxygen demand index is negatively correlated with the blood oxygen saturation. When the user's own blood oxygen saturation is lower, it is necessary to supply oxygen to ensure the user's own physical health.

[0055] Step 130, determining the target oxygen supply mode from the candidate oxygen supply modes according to the oxygen demand index, and determining the value of the oxygen supply parameter according to the oxygen demand index.

[0056] The target oxygen supply mode refers to which path of the vehicle oxygen supply system to supply oxygen according to the above. Based on the vehicle oxygen supply system, the candidate oxygen supply modes include seat headrest diffusion oxygen supply, air conditioner air outlet oxygen supply, and nasal catheter oxygen supply. By different oxygen demand indexes, the current oxygen demand of the user is identified, and the corresponding target oxygen supply mode is selected. For example, in the case of a small oxygen demand index, seat headrest diffusion oxygen supply is selected. Oxygen is diffused and released by the seat headrest diffusion assembly, so that the oxygen supply range is concentrated in the user's head, and the oxygen is supplied without feeling. In the case of a high oxygen demand index, air conditioner air outlet oxygen supply is selected. Oxygen is released through the air conditioner air outlet assembly, so that the overall oxygen environment in the vehicle is improved. Further, in the case of a higher oxygen demand index, nasal catheter oxygen supply is selected. The individual is supplied with oxygen through the nasal catheter assembly.

[0057] For example, different candidate oxygen supply modes are configured with corresponding priority. The higher the priority, the higher the corresponding oxygen supply index. In actual application, the candidate oxygen supply mode with the corresponding priority is selected as the target oxygen supply mode according to the height of the oxygen demand index.

[0058] The configuration mode of the priority is determined based on the actual situation. For example, the seat headrest diffusion oxygen supply is configured as the first priority, the air conditioner air outlet oxygen supply is configured as the second priority, and the nasal catheter oxygen supply is configured as the third priority. The step-by-step oxygen supply strategy balances the comfort and urgency of oxygen supply.

[0059] It can be understood that the number of candidate oxygen supply modes can be more or less according to the specific setting of the vehicle oxygen supply system. For example, the seat headrest diffusion oxygen supply and the air conditioner air outlet oxygen supply are combined as two candidate oxygen supply modes, or the air conditioner air outlet oxygen supply and the nasal catheter oxygen supply are combined as two candidate oxygen supply modes. At least two selectable modes are retained to adjust the oxygen supply based on different actual needs.

[0060] For the oxygen supply parameters, the oxygen supply flow is exemplarily included. The value of the oxygen supply parameter can be adaptively adjusted under different oxygen demand indexes, so as to match the specific oxygen supply demand. This will be further described below.

[0061] The vehicle oxygen supply method provided in the embodiment combines the specific scenario of the vehicle, uses the seat headrest assembly or the air conditioner air outlet assembly as a selectable oxygen supply path, provides the user in the vehicle with an oxygen supply mode combined with the vehicle scenario, and uses the nasal catheter assembly to supply oxygen to the individual, thereby meeting the high oxygen supply demand scenario. By determining the oxygen demand index based on the altitude and the blood oxygen saturation, the degree of oxygen demand in the current environment (altitude) and the user's own state (blood oxygen saturation) can be accurately identified. The oxygen supply mode and the value of the oxygen supply parameter are determined according to the oxygen demand index, and the user is provided with an oxygen supply function that meets the current demand.

[0062] The oxygen demand index is further described as follows:

[0063] In one embodiment, after determining the oxygen demand index according to the altitude and the blood oxygen saturation, the method further comprises:

[0064] obtaining an air circulation mode of the vehicle;

[0065] in a case where the air circulation mode is an internal circulation mode, determining a first compensation coefficient according to a carbon dioxide concentration in the vehicle, wherein the first compensation coefficient is positively correlated with the carbon dioxide concentration, and the first compensation coefficient is greater than or equal to 1;

[0066] adjusting the oxygen demand index according to the first compensation coefficient, so as to determine a target oxygen supply mode and a value of an oxygen supply parameter based on the adjusted oxygen demand index.

[0067] Generally, the air circulation mode of the vehicle includes an external circulation mode and an internal circulation mode. In the external circulation mode, the air conditioning system will suck the air outside the vehicle into the vehicle and send it into the cabin after filtering by the air conditioning filter, so as to keep the air in the vehicle circulating with the outside air and supplement fresh oxygen. In the internal circulation mode, the existing air in the vehicle is recycled and circulated in the closed space of the vehicle without exchanging with the outside air. Therefore, it can be known that in the internal circulation mode, the oxygen content of the air in the vehicle will decrease with the user's breathing, and the carbon dioxide concentration will increase with the user's breathing. Therefore, in the internal circulation mode, the first compensation coefficient is calculated by detecting the carbon dioxide concentration, so as to adjust the oxygen demand index and obtain a more accurate oxygen demand identification result.

[0068] Exemplarily, a basic oxygen demand index D is determined according to the altitude and the blood oxygen saturation, for example, the basic oxygen demand index D is calculated according to the following mathematical expression:

[0069] D = max(0, α1*(h / N) - α2*(spo2 - b1));

[0070] wherein h is the altitude, N is the altitude gradient, spo2 is the current blood oxygen saturation, α1 and α2 are respectively the altitude coefficient and the blood oxygen coefficient, and b1 is the first bias. N, α1, α2 and b1 can be determined according to actual conditions, but it can be known that α1 > 0 and α2 > 0.

[0071] Exemplarily, D = max(0, 0.5*(h / 1000) - 0.1*(spo2 - 90)) is configured.

[0072] At this time, spo2 is the molecular part of the current blood oxygen saturation, for example, the current blood oxygen saturation is 95%, and spo2 is recorded as 95 for calculation.

[0073] It can be seen that the oxygen demand index D is minimum 0, and increases by 0.5 for each 1000m increase in altitude h, and the oxygen demand index D increases by 0.1 for each 1% decrease in blood oxygen saturation.

[0074] The first compensation coefficient is defined as a1 (a1≥1), and is determined according to the carbon dioxide concentration co2, for example, according to the following mathematical expression:

[0075] a1=b2+α3*co2 / M;

[0076] wherein b2 is a second bias, α3 is a concentration coefficient, and α3 is greater than 0, and M is a concentration gradient.

[0077] For example, a1=1.2+0.05*co2 / 1000;

[0078] The carbon dioxide concentration co2 is calculated in terms of parts per million (ppm).

[0079] The adjusted oxygen demand index D'=a1*D.

[0080] The first compensation coefficient is positively correlated with the carbon dioxide concentration, that is, the higher the carbon dioxide concentration, the greater the first compensation coefficient, and the greater the adjusted oxygen demand index.

[0081] In the case of the external circulation mode in the vehicle, the first compensation coefficient a1 is recorded as 1.

[0082] In another embodiment, another compensation method is provided for the emergency situation of excessively low blood oxygen saturation, for example:

[0083] After determining the oxygen demand index according to the altitude and the blood oxygen saturation, it further includes:

[0084] In the case where the altitude is greater than the altitude threshold and the blood oxygen saturation is less than the blood oxygen threshold, a second compensation coefficient is determined according to the blood oxygen saturation, wherein the second compensation coefficient is negatively correlated with the blood oxygen saturation, and the second compensation coefficient is greater than or equal to 1;

[0085] The oxygen demand index is adjusted according to the second compensation coefficient, to determine the target oxygen supply mode and the numerical value of the oxygen supply parameter based on the adjusted oxygen demand index.

[0086] wherein the altitude threshold is, for example, 3000m, or other height values that can define high altitude or low altitude, and the blood oxygen threshold indicates the blood oxygen safety value at the current altitude, which is determined based on typical values that can define the normal physiological state and the hypoxic state of the human body, for example, at an altitude of 3000m, the blood oxygen saturation of the human body is usually in the range of 88% to 92%, and therefore, the blood oxygen threshold can be set to 88%.

[0087] It can be understood that the blood oxygen threshold value can be a fixed value or a dynamic value negatively correlated with the altitude.

[0088] The following Table 1 exemplarily lists the reference spo2 and blood oxygen threshold value at different altitudes.

[0089] Table 1:

[0090] Altitude (m) Baseline SpO2 (%) Oxygen threshold (%) ＜1500 98 94 1500-3000 95 90 ＞3000 92 88

[0091] In actual implementation, different altitudes can be determined as altitude threshold values according to actual conditions, and the blood oxygen threshold value is determined according to the altitude.

[0092] Exemplarily, the second compensation coefficient is determined according to the following mathematical expression:

[0093] a2=α4*(b3+(S-spo2) / P);

[0094] Wherein, a2 is the second compensation coefficient, α4 is the adjustment ratio, b3 is the third offset, S is the blood oxygen threshold value, spo2 is the current blood oxygen saturation, and P is the blood oxygen gradient. Exemplarily, it is defined as:

[0095] a2=1.5*(1+(88-spo2) / 10);

[0096] The blood oxygen saturation spo2 is still taken as the numerator for calculation.

[0097] As can be seen, when the blood oxygen saturation is lower than 88%, the second compensation coefficient increases by 15% for every 1% decrease.

[0098] The oxygen demand index D is adjusted based on the second compensation coefficient a2, and the adjusted oxygen demand index D'=a2*D.

[0099] In another embodiment, the oxygen demand index D is adjusted based on the first compensation coefficient and the second compensation coefficient, and the adjusted oxygen demand index D'=a1*a2*D.

[0100] By monitoring the carbon dioxide concentration in the vehicle internal circulation mode and identifying the extreme hypoxia condition, the accuracy of the oxygen demand identification is improved.

[0101] In one embodiment, the possible range of the oxygen demand index is divided, the current range of the oxygen demand index is judged, and the target oxygen supply mode is determined, specifically:

[0102] In the case that the oxygen demand index is in the first interval, oxygen is supplied through the seat headrest;

[0103] In the case that the oxygen demand index is in the second interval, oxygen is supplied through the air outlet of the air conditioner;

[0104] When the oxygen demand index is in the third interval, oxygen is supplied through a nasal catheter;

[0105] The upper limit value of the first interval is less than the lower limit value of the second interval, and the upper limit value of the second interval is less than the lower limit value of the third interval.

[0106] When the oxygen demand index fluctuates within a certain range, the hierarchical response strategy is adopted, and the oxygen supply path does not need to be switched.

[0107] The following describes the oxygen supply parameters:

[0108] The oxygen supply parameters include the oxygen supply flow rate. In one embodiment, the oxygen supply flow rate is determined according to the oxygen demand index; wherein the oxygen supply flow rate is positively correlated with the oxygen demand index.

[0109] That is, when the oxygen demand index is low, low flow is used for oxygen supply, and when the oxygen demand index is high, high flow is used for oxygen supply.

[0110] In particular, in combination with the division of the oxygen demand index range in the foregoing embodiments, when the oxygen demand index is in the first interval, the first flow rate is used for oxygen supply; when the oxygen demand index is in the second interval, the second flow rate is used for oxygen supply; when the oxygen demand index is in the third interval, the third flow rate is used for oxygen supply, the third flow rate is greater than the second flow rate, and the second flow rate is greater than the first flow rate.

[0111] The first flow rate, the second flow rate, and the third flow rate can allow a certain fluctuation range of flow rate, for example, the range corresponding to the first flow rate is [0.5, 1), the range corresponding to the second flow rate is [1, 3), and the range corresponding to the third flow rate is [3, 8], all in units of L / min.

[0112] Further, in combination with a specific target oxygen supply mode, when the oxygen demand index is in the first interval, the first flow rate is used for oxygen supply through the seat headrest diffusion; when the oxygen demand index is in the second interval, the second flow rate is used for oxygen supply through the air outlet of the air conditioner; and when the oxygen demand index is in the third interval, the third flow rate is used for oxygen supply through the nasal catheter.

[0113] When the seat headrest diffusion oxygen supply is used, a smaller flow rate can be used to avoid directly blowing the user's head, and a larger flow rate is used for nasal catheter oxygen supply to quickly provide more oxygen to the user.

[0114] The oxygen supply parameters include the humidity of the oxygen, and in one embodiment, the humidity of the oxygen is determined according to the oxygen supply flow rate; wherein the humidity is positively correlated with the oxygen supply flow rate.

[0115] The specific calculation of the humidity is based on the respiratory water loss dynamic model, and the corresponding humidity is obtained according to the evaporation amount and the compensation demand.

[0116] Exemplarily, when the oxygen demand index is in the first interval, oxygen is supplied by the seat headrest at a first flow rate and a first humidity; when the oxygen demand index is in the second interval, oxygen is supplied by the air outlet of the air conditioner at a second flow rate and a second humidity; and when the oxygen demand index is in the third interval, oxygen is supplied by the nasal catheter at a third flow rate and a third humidity, the first humidity being less than the second humidity, and the second humidity being less than the third humidity.

[0117] When oxygen is supplied by the seat headrest, the headrest is filled with fabric or other fillings, and oxygen with a lower humidity is used for diffusion and release, which is beneficial to keeping the headrest dry; when oxygen is supplied by the air outlet of the air conditioner, the humidity of the inhaled gas of the user is jointly affected by the humidity of the vehicle and the oxygen supply humidity, and the oxygen humidity is set with reference to the typical value of the humidity of the vehicle; when oxygen is supplied by the nasal catheter, the humidity of the inhaled gas of the user is mainly affected by the oxygen supply humidity, and a higher humidity is beneficial to keeping the throat of the user moist and improving the comfort of the user.

[0118] Exemplarily, the setting of the oxygen supply mode and the oxygen supply parameters is shown in Table 2.

[0119] Table 2:

[0120] Oxygen demand index Delivery mode Oxygen flow (L / min) Humidity [0，0.3) Seat headrest diffuse oxygen [0.5，1) 40% RH [0.3,0.6) Air-conditioned outlet oxygen [1，3) 50% RH [0.6,1.0] Nasal cannula oxygen [3，8] 60% RH

[0121] In actual implementation, when the oxygen demand index is in the first interval, oxygen is supplied by the seat headrest at a first flow rate, and a first humidity and a first temperature compensation amount are used; when the oxygen demand index is in the second interval, oxygen is supplied by the air outlet of the air conditioner at a second flow rate, and a second humidity and a second temperature compensation amount are used; and when the oxygen demand index is in the third interval, oxygen is supplied by the nasal catheter at a third flow rate, and a third humidity and a third temperature compensation amount are used.

Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, Figure 2 at least part of the steps in the flowchart can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or sub-steps or stages of other steps.
