[0015] Refer to Figure 1 , Figure 1It is a schematic diagram of an oxygen supply device provided by an embodiment of the present application assembled in a vehicle. The oxygen supply device includes components such as an intake air filter 4, an air compressor 5, an oxygen generation component 6, a muffler 8, an oxygen sensor 1, etc. The oxygen supply device utilizes the adsorption capacity difference of different gas molecules in the air by molecular sieves, and separates oxygen through a periodic pressurized adsorption and depressurized desorption process. It can be integrated on the vehicle. Specifically, the intake air filter 4 is used to filter impurities such as dust, particulate matter, and water vapor in the air, avoiding contamination of the compressor and molecular sieve, and ensuring the cleanliness of the air entering the system. The air compressor 5 is used to do work on the air through mechanical motion (such as piston type, screw type), compress the outside air, increase the density of air molecules, so that gases such as nitrogen and oxygen in the air enter the oxygen generation component 6 in a high-pressure state. The oxygen generation component 6 can include a molecular sieve and a controller. Among them, the oxygen generation component 6 is used to preferentially adsorb nitrogen, carbon dioxide, and water vapor after high-pressure air enters the molecular sieve tower, so that oxygen is separated as the unadsorbed gas and output through a pipeline. When the molecular sieve is saturated with adsorption, the adsorbed nitrogen and other impurities are released by pressure relief to restore the adsorption capacity and prepare for the next cycle. The controller is used to control the operation cycle of the entire oxygen supply device, such as starting and stopping the compressor, switching the pressurization / decompression of the molecular sieve tower, etc. The muffler 8 is connected to the air compressor 5 and is used to reduce the noise during the operation of the compressor. The oxygen sensor 1 is used to monitor the oxygen concentration inside the vehicle as reference data for adjusting the oxygen supply mode or oxygen supply rate. Components such as the intake air filter 4, the air compressor 5, and the oxygen generation component 6 can be connected through ventilation pipelines to form a circulation channel for oxygen or other waste gases. In addition, the installation position and number of oxygen sensors can be selected according to actual needs, and are not limited in the embodiments of the present application.

[0016] Furthermore, the oxygen supply device can be connected to the air supply pipeline of the vehicle-mounted air conditioner. Specifically, the oxygen supply device can be connected to the rear HVAC interface 7. When the HVAC fan is operating, an air flow negative pressure (or positive pressure) is formed in the air supply pipeline, and the oxygen output by the oxygen supply device is injected into the air supply pipeline through the interface, mixed with fresh air / return air, and evenly diffused into the space through the oxygen diffusion outlet 2.

[0017] Reference Figure 1 , the present application can achieve diffused oxygen supply. The oxygen supply device can be connected to the rear HVAC interface, and oxygen is evenly released into the vehicle through the oxygen diffusion outlet to increase the oxygen concentration in the environment. The oxygen supply device in the present application can also achieve nasal inhalation oxygen supply. The oxygen generated by the oxygen supply device can pass through the nasal inhalation pipeline and be supplied to the user through the nasal inhalation oxygen outlet 3. Multiple nasal inhalation oxygen outlets can be arranged according to the layout inside the vehicle. For example, they can be arranged at positions such as the front row glove box, COSL storage box, side of the seat, and lower part of the center console.

[0018] Reference Figure 2 , Figure 2A vehicle oxygen supply method provided by an embodiment of the present application. The vehicle is equipped with an oxygen supply device, and the oxygen supply device is connected to the air supply duct of the vehicle-mounted air conditioner. The method includes: Step 101, obtain the oxygen supply mode of the vehicle and the operating state of the vehicle-mounted air conditioner.

[0019] In an embodiment of the present application, the vehicle is equipped with an oxygen supply device, and the oxygen supply device is connected to the air supply duct of the vehicle-mounted air conditioner. The connection method may be that the oxygen supply device is connected to the rear HVAC interface. The oxygen supply device may be a device that separates oxygen from air.

[0020] The oxygen supply mode of the vehicle may be diffused oxygen supply or nasal inhalation oxygen supply. Diffused oxygen supply means connecting through a pipeline to the air supply duct interface of the HVAC system, and using the fan and air duct network of the HVAC to diffuse oxygen to the target area. Nasal inhalation oxygen supply means that the oxygen generated by the oxygen supply device is provided to the user through the nasal inhalation pipeline arranged in the vehicle.

[0021] The operating state of the vehicle-mounted air conditioner may indicate whether the vehicle-mounted air conditioner is operating, such as whether it is turned on, whether it is in a cooling or heating state, etc.

[0022] Since the diffused oxygen supply in the present application needs to use the fan and air duct network of the vehicle-mounted air conditioner to diffuse and output to the users in the vehicle, therefore, the oxygen supply mode of the vehicle and the operating state of the vehicle-mounted air conditioner can be obtained first to achieve diffused oxygen supply in the vehicle.

[0023] It should be noted that the oxygen supply mode of the vehicle may be a mode actively selected by the user through interaction with the central control screen in the vehicle, or a vehicle-based oxygen supply mode that automatically turns on diffused oxygen generation based on the altitude or location where the vehicle is located, etc.

[0024] Step 102, if the oxygen supply mode is diffused oxygen supply and the operating state of the vehicle-mounted air conditioner is in the off state, then adjust the operating state of the vehicle-mounted air conditioner to the external circulation, and obtain the fogging risk level of the vehicle's glass and the vehicle speed.

[0025] In an embodiment of the present application, diffused oxygen supply is to release oxygen into the vehicle through an oxygen supply device to increase the oxygen concentration in the vehicle. When the vehicle adopts the diffused oxygen supply mode and the vehicle-mounted air conditioner is in the off state, the air conditioner needs to be adjusted to the external circulation mode.

[0026] The external circulation of the vehicle air conditioner is used to introduce fresh air from outside the vehicle. The core components for realizing the external circulation are the blower and the air damper. Among them, the blower is used to drive the air flow, and the air damper is used to control the intake air volume. If the oxygen supply mode is diffused oxygen supply, since the oxygen supply device is connected to the air supply duct of the vehicle air conditioner in this application, therefore, during diffused oxygen supply, the blower in the external circulation channel can be used for air supply. After the oxygen produced by the oxygen supply device is mixed with the air introduced by the external circulation, it is blown into the vehicle to realize oxygen supply. For vehicles with an independently controllable rear air conditioner, the rear HVAC interface is connected to the oxygen supply device. When diffused oxygen supply is turned on, if the rear air conditioner is in the off state, only the external circulation of the rear air conditioner can be turned on, and the air outlet setting can be set to the air outlet mode corresponding to the current demand, such as face blowing and / or foot blowing, etc. The state of the front air conditioner can remain unchanged. If the rear air conditioner is in the on state after diffused oxygen supply is turned on, the state of the rear air conditioner can be left unchanged, so that the oxygen is mixed with the cold air or warm air of the rear air conditioner and output.

[0027] Specifically, after the blower is started, it inhales the air outside the vehicle through the external circulation air damper. The high-concentration oxygen produced by the oxygen supply device is mixed with the external circulation air in the air supply duct to form a mixed gas. The mixed gas is blown into the vehicle through the air outlets of the air conditioner (such as the front windshield, side window, and foot air outlets). Using the air pressure of the blower to promote the air flow circulation can avoid local accumulation of oxygen. That is, when this application realizes diffused oxygen supply, it reuses the existing hardware of the air conditioning system, reduces costs and weight. At the same time, using the original air outlet network of the air conditioner, it realizes the effect of uniform air supply in multiple areas. By using the external circulation blower, the oxygen supply demand in the vehicle can be realized without starting the air conditioning refrigeration or heating.

[0028] Furthermore, after the vehicle turns on the external circulation, the air from outside the vehicle introduced by the external circulation may be at a relatively low temperature or high humidity. After being mixed with the warm air inside the vehicle, it is easy to cause fogging on the glass surface. Therefore, this application further obtains the fogging risk level of the vehicle's glass and the vehicle speed. The fogging risk level is used to describe the degree of fogging of the vehicle's glass. The higher the fogging risk level, the higher the degree of fogging of the vehicle's glass. The speed of the vehicle affects the intake air volume of the external circulation. Therefore, after diffused oxygen supply is turned on, this application further obtains the fogging risk level and the vehicle speed to handle the possible fogging situation.

[0029] The fogging risk level can be calculated and determined by obtaining data such as the temperature difference between inside and outside the vehicle and the humidity outside the vehicle. The data such as the temperature difference between inside and outside the vehicle and the humidity outside the vehicle can be collected through the vehicle's own temperature and humidity sensors, etc. The greater the temperature difference, the higher the fogging risk, and the greater the humidity, the higher the fogging risk. The fogging risk level can be correspondingly determined according to the obtained temperature difference and humidity data.

[0030] The vehicle speed can be determined by a vehicle speed sensor. When the vehicle is traveling at a high speed, the external airflow is strong and the intake volume of the external circulation is relatively large, which may affect the oxygen concentration inside the vehicle. Therefore, this application also obtains the vehicle speed and the fogging risk level to adjust the opening degree of the air door, so as to ensure the oxygen concentration inside the vehicle and avoid excessive fogging of the glass, which may affect driving safety.

[0031] Step 103: Adjust the opening degree of the air door of the external circulation according to the fogging risk level and the vehicle speed, so as to reduce the fogging degree of the glass of the vehicle when the oxygen prepared by the oxygen supply device is transported to the vehicle through the air supply pipeline; the fogging risk level is determined according to the environmental parameters of the vehicle and is used to reflect the fogging degree of the glass of the vehicle, and the fogging risk level is in a direct proportional relationship with the fogging degree of the glass of the vehicle.

[0032] In the embodiment of this application, when transporting the oxygen prepared by the oxygen supply device into the vehicle through the air supply pipeline, the opening degree of the external circulation air door can be dynamically adjusted to achieve a balance between the oxygen transportation efficiency and the glass anti-fogging requirements.

[0033] The fogging risk level is determined according to the environmental parameters of the vehicle. The environmental parameters include the temperature and humidity parameters inside and outside the vehicle, the glass temperature, etc. The fogging risk level can be calculated according to the environmental parameters. The higher the fogging risk level, the higher the fogging degree of the glass. The higher the humidity inside the vehicle, the easier the water vapor condenses. When the temperature inside the vehicle is high, the saturation concentration of water vapor is high. When the temperature outside the vehicle is low, the glass is easily cooled to the dew point, and the glass temperature can determine whether the dew point temperature is reached. According to the above-mentioned collected parameters, the fogging risk level can be calculated. For example, the fogging risk level can be divided into level 0 to level 4. Among them, level 0 means there is no fogging risk, level 1 means approaching fogging, level 2 means there is a fogging risk at the glass corners. Level 3 means there is a fogging risk on the front windshield, and level 4 means it has already fogged. At this time, according to the fogging risk level, the opening degree of the air door can be adjusted to adjust the intake volume of the external circulation and reduce the fogging risk degree of the glass.

[0034] Further, under driving conditions, the higher the vehicle speed, the greater the intake volume of the external circulation. At high vehicle speeds, the opening degree of the air door can be compensated and corrected to ensure the oxygen concentration inside the vehicle.

[0035] This application dynamically adjusts the opening degree of the air door, gives priority to anti-fogging when the fogging risk is high, gives priority to ensuring oxygen supply and increasing the air door when the fogging risk is low, and dynamically corrects the opening degree of the air door in combination with the vehicle speed, achieving a balance between oxygen supply efficiency and anti-fogging performance during the diffusion oxygen supply process.

[0036] In summary, in the embodiment of the present application, an oxygen supply device is installed in the vehicle. The oxygen supply device is connected to the air supply duct of the vehicle-mounted air conditioner, and the oxygen supply mode of the vehicle and the operating state of the vehicle-mounted air conditioner are obtained. If the oxygen supply mode is diffused oxygen supply and the operating state of the vehicle-mounted air conditioner is the closed state, the operating state of the vehicle-mounted air conditioner is adjusted to the external circulation, and the fogging risk level of the vehicle's glass and the vehicle speed are obtained. According to the fogging risk level and the vehicle speed, the opening degree of the external circulation damper is adjusted so that during the process of the air supply duct delivering the oxygen prepared by the oxygen supply device to the vehicle, the fogging degree of the vehicle's glass is reduced. The fogging risk level is determined according to the environmental parameters of the vehicle and is used to reflect the fogging degree of the vehicle's glass. The fogging risk level is in a direct proportional relationship with the fogging degree of the vehicle's glass. The method of the present application installs an oxygen supply device inside the vehicle. By linking the oxygen supply device with the vehicle-mounted air conditioner, the oxygen prepared by the oxygen supply device is output to the users inside the vehicle through the air supply duct of the vehicle-mounted air conditioner. At the same time, during the oxygen supply process, the fogging risk of the vehicle glass is considered, and based on the fogging risk and the vehicle speed, the opening ratio of the external circulation is adjusted so that during the vehicle driving process, oxygen supply and driving safety can be taken into account. The oxygen supply method of the present application saves the available space of the vehicle compared with the prior art. At the same time, it can meet the oxygen supply requirements under different environmental conditions.

[0037] Reference Figure 2 , Figure 2 is another vehicle oxygen supply method provided by the embodiment of the present application. An oxygen supply device is installed in the vehicle. The oxygen supply device is connected to the air supply duct of the vehicle-mounted air conditioner. The method includes: Step 201, obtain the oxygen supply mode of the vehicle and the operating state of the vehicle-mounted air conditioner.

[0038] This step can refer to step 101 and will not be elaborated here.

[0039] Step 202, if the oxygen supply mode is diffused oxygen supply and the operating state of the vehicle-mounted air conditioner is the closed state, adjust the operating state of the vehicle-mounted air conditioner to the external circulation, and obtain the fogging risk level of the vehicle's glass and the vehicle speed.

[0040] This step can refer to step 102 and will not be elaborated here.

[0041] Step 203, determine the allowable range of the damper opening degree, the adjustment time interval of the damper opening degree, and the target opening degree value corresponding to each adjustment according to the fogging risk level and the vehicle speed; the target opening degree value belongs to the allowable range.

[0042] In the embodiments of the present application, there is a corresponding relationship between the fogging risk level, vehicle speed, and the allowable range of the air door opening, the adjustment time interval of the air door opening, and the target opening value corresponding to each adjustment. Among them, the allowable range of the air door opening is used to represent the maximum and minimum proportions of the air door opening. For example, it can be 40% to 100%. The adjustment time interval of the air door opening is used to represent the interval time for adjusting the air door opening once. For example, if it is 10 seconds, the air door opening is adjusted once every 10 seconds. If it is 30 seconds, the air door opening is adjusted once every 30 seconds. The target opening value corresponding to each adjustment is the target value to which the air door opening is adjusted during adjustment. For example, if the initial air door opening is 80% and it is reduced by 5% each time, then for the first adjustment, the target opening value is 75%. When adjusting again after an interval of 10 seconds, the target opening value is 70%, and so on. If the allowable range of the air door opening is 40% to 100%, then the lowest air door opening for this adjustment is adjusted to 40%, and the target opening value for each adjustment is within the allowable range.

[0043] In the embodiments of the present application, the adjustment of the air door opening can be automatically realized. For example, it can be realized in an automatic cycle mode. During adjustment, starting from the current opening, the range of the air door opening is corrected during the adjustment process under the constraints of the fogging risk level and vehicle speed to ensure that the fogging degree of the vehicle does not affect driving safety and the oxygen concentration in the vehicle meets the user's needs.

[0044] Optionally, step 203 includes: Sub-step 2031, determining a first allowable range of the air door opening according to the fogging risk level; Sub-step 2032, determining a second allowable range of the air door opening according to the fogging risk level and vehicle speed; Sub-step 2033, if the first allowable range is different from the second allowable range, then taking the second allowable range as the target allowable range of the air door opening; Among them, if the fogging risk levels are the same, the higher the vehicle speed, the lower the lower limit value of the second allowable range; if the vehicle speeds are the same, the higher the fogging risk level, the higher the lower limit value of the second allowable range.

[0045] In the embodiments of the present application, for sub-steps 2031 to 2033, for example, Table 1 provides a corresponding relationship between the fogging risk level and the air door opening: Table 1

[0046] The fogging risk levels include: Lv0 to Lv4. Among them, for Lv0, the allowable range of the circulation air damper opening when parking / idling is: 0% - 100%. After the diffusion oxygen generation is turned on, the action of the circulation air damper is: close by 5% every 10s, that is, the adjustment time interval of the air damper opening is 10s, and each adjustment is reduced by 5% based on the previous one, and the minimum air damper opening is 0%. For Lv1, the allowable range of the circulation air damper opening when parking / idling is: 40% - 100%. After the diffusion oxygen generation is turned on, the action of the circulation air damper is: close by 5% every 30s, that is, the adjustment time interval of the air damper opening is 30s, and each adjustment is reduced by 5% based on the previous one, and the minimum air damper opening is 40%. For Lv2, the allowable range of the circulation air damper opening when parking / idling is: 60% - 100%. After the diffusion oxygen generation is turned on, the action of the circulation air damper is: close by 5% every 60s, that is, the adjustment time interval of the air damper opening is 60s, and each adjustment is reduced by 5% based on the previous one, and the minimum air damper opening is 60%. For Lv3, the allowable range of the circulation air damper opening when parking / idling is: 100%. After the diffusion oxygen generation is turned on, the action of the circulation air damper is: restore to 100% external circulation. For Lv4, the allowable range of the circulation air damper opening when parking / idling is: 100%. After the diffusion oxygen generation is turned on, the action of the circulation air damper is: restore to 100% external circulation. That is, when the fogging risk level is relatively low, such as Lv0 to Lv2, the air damper opening can be gradually reduced until reaching the lower limit value of the allowable range. When the fogging risk level is relatively high, such as Lv3 to Lv4, it can be restored to 100% external circulation to give priority to ensuring driving safety.

[0047] Furthermore, the corresponding relationship between the vehicle speed and the air damper opening is shown in Table 2. Under driving conditions, the higher the vehicle speed, the greater the external circulation air intake. For high vehicle speeds, the allowable air damper opening should be compensated and corrected as follows: Table 2

[0048] Among them, if the fogging risk levels are the same, the higher the vehicle speed, the lower the lower limit value of the second allowable range; if the vehicle speeds are the same, the higher the fogging risk level, the higher the lower limit value of the second allowable range. For example, when the vehicle speed is 0 < V ≤ 30 km / h and the fogging risk level is Lv1 (close to fogging), the lower limit value of the allowable range of the air damper opening is 40%. When the fogging risk level is Lv2 (there is a fogging risk at the corners), the lower limit value of the allowable range of the air damper opening is 60%. When adjusting the air damper opening, if the fogging risk level is Lv1, if the first allowable range determined according to the fogging risk level is 40% - 100%, and if the vehicle speed is 0 < V ≤ 30 km / h, then the second allowable range is 36% to 100%, that is, modify the lower limit value of the first allowable range of the air damper opening to make up for the in-vehicle oxygen concentration when the vehicle speed is too fast.

[0049] Step 204: Adjust the air door opening of the external circulation according to the allowable range of the air door opening, the adjustment time interval of the air door opening, and the target opening value corresponding to each adjustment.

[0050] In the embodiment of the present application, after determining the allowable range of the air door opening, the adjustment time interval of the air door opening, and the target opening value corresponding to each adjustment in step 203, the air door opening of the external circulation can be adjusted according to the above strategy. For example: when the fogging risk level is Lv0, the allowable range of the circulating air door opening during parking / idling is: 0% - 100%. After the dispersed oxygen generation is turned on, the action of the circulating air door is: close by 5% every 10s, that is, the adjustment time interval of the air door opening is 10s, and each adjustment is reduced by 5% on the basis of the previous one, and the minimum air door opening is 0%.

[0051] Optionally, step 204 includes: Sub-step 2041: Determine the initial air door opening of the current external circulation; Sub-step 2042: If the fogging risk level belongs to the first range, on the basis of the initial air door opening, gradually reduce the air door opening according to the adjustment time interval of the air door opening and the target opening value corresponding to each adjustment until the initial air door opening is adjusted to the lower limit value of the allowable range.

[0052] Sub-step 2043: If the fogging risk level belongs to the second range, directly adjust the initial air door opening to the upper limit value of the allowable range.

[0053] In the embodiment of the present application, for sub-step 2041 and sub-step 2043, when adjusting the air door opening, starting from the current opening, during the adjustment process, it is restricted by the fogging risk level and vehicle speed, and the range of the air door opening is corrected to ensure that the fogging degree of the vehicle does not affect driving safety and the oxygen concentration in the vehicle meets the user's needs.

[0054] Specifically, the initial damper opening of the current outer loop can be determined, for example, as 80%. If the fogging risk level belongs to the first range, the first range can be from Lv0 to Lv2. That is, when the fogging risk level is relatively low, the damper opening can be gradually reduced until the lower limit value of the allowable range is reached. For example, when the fogging risk level is Lv0, the allowable cyclic damper opening range during parking / idle is: 0% - 100%. After the diffusion oxygen generation is turned on, the action of the cyclic damper is: close 5% every 10 s, that is, the adjustment time interval of the damper opening is 10 s, and each adjustment reduces by 5% based on the previous time. The minimum damper opening is 0%. That is, with 80% as the initial damper opening, at an interval of 10 seconds, for the first adjustment, the target opening value is 75%. After another 10 seconds, for the second adjustment, the target opening value is 70%, and it is gradually reduced until the lower limit value of the allowable range, that is, 0%, can be reached. If the fogging risk level belongs to the second range, that is, when the fogging risk level is relatively high, such as Lv3 to Lv4, the outer loop can be restored to 100%, for example, if the initial damper opening is 80%, it is adjusted to 100% to give priority to ensuring driving safety.

[0055] Optionally, an oxygen sensor is installed inside the vehicle, and the method includes: Step 205, in response to a selection operation for any one of a plurality of oxygen output modes, determine a target oxygen output mode; different oxygen output modes correspond to different preset values of the in-vehicle oxygen concentration; Step 206, obtain the in-vehicle oxygen concentration value collected by the oxygen sensor; Step 207, if the in-vehicle oxygen concentration value reaches the preset value of the in-vehicle oxygen concentration corresponding to the target oxygen output mode, adjust the oxygen output efficiency of the oxygen supply device so that the in-vehicle oxygen concentration value remains at the preset value of the in-vehicle oxygen concentration.

[0056] In the embodiment of the present application, for steps 205 to 207, an oxygen sensor is installed inside the vehicle, and the oxygen sensor can monitor and record the oxygen concentration inside the vehicle. The oxygen output mode is used to correspond to different usage scenarios. For example, the oxygen output mode can include: "Relaxation and Stress Relief", "Health Care", and "Traveling on the Plateau". Since users in different modes have different oxygen demands, each oxygen output mode corresponds to a different preset value of the in-vehicle oxygen concentration, and the preset value of the in-vehicle oxygen concentration is used to represent the upper limit value of the oxygen concentration corresponding to the oxygen output mode. After the user selects any oxygen output mode as the target oxygen output mode, the in-vehicle oxygen concentration value collected by the oxygen sensor can be obtained, and it can be determined whether the current in-vehicle oxygen concentration reaches the preset value of the oxygen concentration. If it reaches, the oxygen output efficiency of the oxygen supply device is adjusted so that the in-vehicle oxygen concentration value remains at the preset value of the in-vehicle oxygen concentration.

[0057] Further, referring to Figure 4 , Figure 4 shows an interface diagram provided by an embodiment of the present application. Among them, the oxygen output modes include: "Relaxing and Decompressing", "Health Care", and "Traveling on the Plateau". Under different modes, the upper limit of the oxygen concentration in the cabin remains at the respective preset values of the oxygen concentration in the vehicle. Users can select the mode by interacting with the interface. The usage methods include: diffusive and nasal inhalation. For example, the default usage method is diffusive, and the oxygen supply rate is 8L / min to 10L / min; after detecting the insertion of the nasal tube, the usage method is switched to nasal inhalation, and the oxygen supply rate is 1L / min to 2L / min. The oxygen supply types include continuous and adaptive modes. The continuous mode continuously supplies oxygen at a constant upper limit of oxygen concentration for a certain period of time; the adaptive mode of oxygen supply can be selected when the user selects the plateau travel mode, and this function option can be hidden under other modes. The oxygen generation duration can be set independently by the user. For example, the default is half an hour, and the maximum is 24 hours. Users can increase or decrease it according to actual needs. The automatic opening and closing setting is used to enter the secondary interface, and the conditions for automatic opening can be set, such as altitude, oxygen concentration in the vehicle, fixed time points, and the linkage trigger of some scenario modes, such as entering a tunnel, nap mode, camping mode, motion sickness relief mode, etc. If these modes are selected, when it is detected that the vehicle is in the corresponding mode, the oxygen supply is automatically turned on.

[0058] Optionally, the method further includes: Step 208, in response to the setting operation of the automatic opening condition of diffusive oxygen supply, determine the automatic opening condition of diffusive oxygen supply; the automatic opening condition includes at least one of altitude, oxygen concentration, fixed time point, and vehicle location; Step 209, under the condition that any one of the determined altitude of the vehicle conforms to the preset altitude, the oxygen concentration in the vehicle is lower than the preset concentration, the current time point is within the preset fixed time point, and the vehicle location is the preset location exists, control the vehicle to perform diffusive oxygen supply.

[0059] In the embodiment of the present application, for steps 208 to 209, in response to the setting operation of the automatic opening condition of diffusive oxygen supply, determine the automatic opening condition of diffusive oxygen supply. For example, referring to Figure 5 , FIG. 5 shows another interface diagram provided by an embodiment of the present application. According to the Figure 5 provided interface, the conditions for automatic opening can be set, such as altitude, oxygen concentration in the vehicle, fixed time point, and the linkage trigger of some scenario modes (such as entering a tunnel, nap mode, camping mode, motion sickness relief mode, etc.).

[0060] Users can interact with Figure 5The interactive operation of the interface is to set the automatic activation conditions for diffused oxygen supply. After the settings are completed, if it is determined based on the vehicle system and various sensors of the vehicle body that the altitude where the vehicle is located meets the preset altitude, the oxygen concentration inside the vehicle is lower than the preset concentration, the current time point is within the preset fixed time point, and the vehicle's location is any one of the preset positions, the vehicle can be controlled to automatically perform diffused oxygen supply to meet the needs of the user.

[0061] Optionally, after step 201, the method further includes: Step 210, if the oxygen supply mode is diffused oxygen supply and the operating state of the vehicle air conditioner is the cooling state or the heating state, then keep the operating state of the vehicle air conditioner unchanged.

[0062] In the embodiment of the present application, if the oxygen supply mode is diffused oxygen supply and the operating state of the vehicle air conditioner is the cooling state or the heating state, then keep the operating state of the vehicle air conditioner unchanged, that is, supply oxygen while cooling or heating, and the oxygen is delivered to the user's vehicle together with the cold air or warm air.

[0063] Furthermore, referring to Table 3, the embodiment of the present application provides a schematic table of the oxygen concentration requirements of the human body at different altitudes.

[0064] Table 3

[0065] The optimal oxygen concentration in the air (volume percentage) is about 20.9%. However, due to the decrease in atmospheric pressure, the partial pressure of oxygen (the actual available amount of oxygen) will decrease, resulting in a reduction in the oxygen intake of the human body. Therefore, the optimal air oxygen concentration required by the human body is not fixed, but needs to be adjusted according to the altitude and the partial pressure of oxygen. As shown in Table 3, through theoretical recommended values combined with vehicle verification, the oxygen concentration requirements of the human body at different altitudes are as shown in Table 3. The vehicle can obtain the altitude in real time. After the diffused oxygen supply is turned on, the oxygen concentration value inside the vehicle is adjusted according to the recommended inspiratory oxygen concentration FiO2 value described in Table 3, so that the user is in an environment with an appropriate oxygen concentration regardless of the altitude, improving the user experience.

[0066] That is, the oxygen supply method of the present application is applicable to multiple scenarios. For example: after a day of work, the user hopes to inhale oxygen for a few minutes to relieve work pressure and refresh the mind, and at this time, the diffused oxygen supply can be turned on. For users on a self-driving trip to the plateau, due to the low oxygen concentration at high altitudes causing dizziness and nausea, the driver and passengers can turn on the diffused oxygen supply to increase the proportion of oxygen concentration in the vehicle air to help the driver and passengers adapt to the plateau environment. It can also be used in medical first aid scenarios. For example, when the driver and passengers have already had altitude sickness or respiratory diseases, the nasal oxygen supply mode can be used to quickly relieve the current discomfort of the user and reduce the symptoms.

[0067] In summary, in the embodiment of the present application, the vehicle is equipped with an oxygen supply device, and the oxygen supply device is connected to the air supply duct of the vehicle air conditioner to obtain the vehicle's oxygen supply mode and the operating state of the vehicle air conditioner; if the oxygen supply mode is diffuse oxygen supply and the operating state of the vehicle air conditioner is off, the operating state of the vehicle air conditioner is adjusted to external circulation, and the fogging risk level of the vehicle's glass and the vehicle speed are obtained; according to the fogging risk level and the vehicle speed, the damper opening of the external circulation is adjusted to reduce the fogging degree of the vehicle's glass in the process of the air supply duct delivering the oxygen prepared by the oxygen supply device to the vehicle; the fogging risk level is determined according to the environmental parameters of the vehicle, and is used to reflect the fogging degree of the vehicle's glass, and the fogging risk level is directly proportional to the fogging degree of the vehicle's glass. The method of the present application installs an oxygen supply device inside the vehicle, and by linking the oxygen supply device with the vehicle air conditioner, the oxygen prepared by the oxygen supply device is output to the user in the vehicle through the air supply duct of the vehicle air conditioner.
