Detailed Implementation

[0026] The following is for reference. Figures 1-3 A vehicle-mounted oxygen supply system 100 according to an embodiment of the first aspect of the present invention is described.

[0027] like Figures 1-3 As shown, the vehicle-mounted oxygen supply system 100 according to a first aspect embodiment of the present invention includes: a supply airflow path 10, a booster 20, a first flow path 30, a second flow path 40, a third flow path 50, and an oxygen storage tank 60.

[0028] Specifically, the supercharger 20 is connected to the air supply path 10, the first end of the first flow path 30 is connected to the supercharger 20, the second end of the first flow path 30 is adapted to connect to the vehicle compartment, the first end of the second flow path 40 is connected to the supercharger 20, and the second end of the second flow path 40 is adapted to connect to the engine 300. The gas in the air supply path 10 flows through the supercharger 20 to the first flow path 30 and / or the second flow path 40 to supply oxygen to the engine 300 and / or the vehicle compartment 200.

[0029] For example, in Figure 1In the example, the first flow path 30 is located between the supercharger 20 and the cabin 200, and the second flow path 40 is located between the supercharger 20 and the engine 300. When the cabin 200 requires oxygen supply, the gas in the supply flow path 10 can flow to the supercharger 20, where it is pressurized to become a high-temperature, high-pressure gas. This high-temperature, high-pressure gas is then cooled, depressurized, and oxygenated through the first flow path 30 to become an oxygen-enriched gas. Finally, the oxygen-enriched gas flows to the cabin 200 to meet the passengers' oxygen needs.

[0030] When the engine 300 needs oxygen supply, the gas in the supply air passage 10 can flow to the turbocharger 20. After being pressurized by the turbocharger 20, it becomes high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled through the second flow passage 40 and flows to the engine 300 to meet the intake requirements of the engine 300.

[0031] Thus, the vehicle oxygen supply system 100 can provide oxygen-enriched gas to the cabin 200 to meet the needs of passengers, and also deliver oxygen-enriched gas to the engine 300 to optimize performance, thereby simultaneously meeting the oxygen needs of both the cabin 200 and the engine 300.

[0032] According to an embodiment of the present invention, the vehicle-mounted oxygen supply system 100 provides two independent flow paths, a first flow path 30 and a second flow path 40, so that the gas in the supply flow path 10 flows through the booster 20 to the first flow path 30 and / or the second flow path 40. Therefore, this application provides a highly efficient, highly integrated, and safe vehicle-mounted oxygen supply system 100, allowing oxygen-rich gas to flow to both the vehicle cabin 200 and the engine 300, thus meeting the dual requirements of comfort in the vehicle cabin 200 and performance of the engine 300. It effectively overcomes the high-altitude performance degradation of the engine 300 while maintaining the oxygen content in the vehicle cabin 200, thereby suppressing altitude sickness in occupants and the driver.

[0033] According to some embodiments of the present invention, the vehicle-mounted oxygen supply system 100 further includes a third flow path 50 and a gas mixer 70. A first end of the third flow path 50 is connected to a first flow path 30. A first inlet of the gas mixer 70 is connected to a supply flow path 10. A second inlet of the gas mixer 70 is connected to a second end of the third flow path 50. The outlet of the gas mixer 70 is connected to a booster 20. (Refer to...) Figure 1 The gas mixer 70 is disposed between the supply gas path 10 and the third flow path 50, and the gas in the gas mixer 70 can flow to the engine 300 via the booster 20 and the second flow path 40.

[0034] Specifically, when the engine 300 needs oxygen supply, the gas in the supply airflow path 10 can flow to the turbocharger 20, and at the same time, the oxygen-enriched gas in the first flow path 30 can flow to the turbocharger 20 through the third flow path 50 and the gas mixer 70. After being pressurized by the turbocharger 20, it becomes a high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled through the second flow path 40 and flows to the engine 300 to deliver oxygen-enriched gas to the engine 300 to optimize its performance, realize oxygen replenishment for the engine 300, and meet the intake requirements of the engine 300.

[0035] Furthermore, the on-board oxygen supply system 100 also includes an exhaust gas recirculation path 80. The first end of the exhaust gas recirculation path 80 is adapted to connect with the exhaust system of the engine 300, and the second end of the exhaust gas recirculation path 80 is connected with the third inlet of the gas mixer 70. Exhaust gas emitted from the engine 300 can be cooled by the exhaust gas recirculation path 80 and then flow to the gas mixer 70. Simultaneously, oxygen-enriched gas from the first path 30 flows to the gas mixer 70 via the third path 50. The exhaust gas and oxygen-enriched gas are mixed and then used for the intake of the engine 300 via the turbocharger 20 and the second path 40, thereby improving the combustion efficiency and environmental performance of the engine 300.

[0036] In addition, for oxygen replenishment of engine 300, the first flow path 30 is connected to the gas mixer 70 through the third flow path 50, and the exhaust system of engine 300 is connected to the gas mixer 70 through the exhaust gas recirculation flow path 80. Compared with the exhaust gas of engine 300 being directly connected to the intake manifold or cylinder of engine 300, the on-board oxygen supply system 100 optimizes the delivery path of oxygen-enriched gas, which facilitates the delivery of oxygen-enriched gas.

[0037] According to some specific embodiments of the present invention, the exhaust gas recirculation path 80 includes a first cooler 810 and a first control valve 820. A first end of the first cooler 810 is adapted to communicate with the exhaust system of the engine 300, and both ends of the first control valve 820 are respectively connected to a second end of the first cooler 810 and a third inlet of the gas mixer 70. Figure 1 As shown, the first cooler 810 is located adjacent to the exhaust system of the engine 300 to cool the high-temperature exhaust gas flowing from the engine 300. A first control valve 820 is located between the first cooler 810 and the gas mixer 70. When the first control valve 820 is open, it allows the low-temperature exhaust gas in the first cooler 810 to flow into the gas mixer 70, where it mixes with oxygen-enriched gas before flowing to the engine 300. Therefore, by installing the first cooler 810, the exhaust gas temperature can be effectively reduced, preventing damage to the gas mixer 70 caused by high-temperature exhaust gas.

[0038] According to some specific embodiments of the present invention, refer to Figure 2The booster 20 includes a first compressor 210 and a second compressor 220. The first end of the first compressor 210 is connected to the outlet of the gas mixer 70, and the second end of the first compressor 210 is connected to the first end of the second flow path 40. The first end of the second compressor 220 is connected to the supply gas path 10, and the second end of the second compressor 220 is connected to the first end of the first flow path 30. When the booster 20 is operating, at least one of the first compressor 210 and the second compressor 220 is in a boosted state.

[0039] Specifically, when the cabin 200 needs oxygen supply, the gas in the supply flow path 10 can flow to the second compressor 220. After being pressurized by the second compressor 220, it becomes high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled and depressurized and oxygenated through the first flow path 30 to become oxygen-enriched gas. Finally, the oxygen-enriched gas in the first flow path 30 flows to the cabin 200 to meet the oxygen needs of the passengers.

[0040] When the engine 300 needs oxygen supply, the gas in the supply airflow path 10 can flow to the first compressor 210. At the same time, the oxygen-enriched gas in the first flow path 30 can flow to the first compressor 210 through the third flow path 50 and the gas mixer 70. After being pressurized by the first compressor 210, it becomes a high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled through the second flow path 40 and flows to the engine 300 to deliver oxygen-enriched gas to the engine 300 to optimize performance and meet the intake requirements of the engine 300.

[0041] Thus, the first compressor 210 independently pressurizes the gas from the gas mixer 70, and the second compressor 220 can directly and independently pressurize the gas from the supply gas path 10, ensuring that the pressurization processes of the two gas paths do not interfere with each other and avoid gas mixing, thereby meeting the gas pressure requirements of the vehicle oxygen supply system 100.

[0042] Furthermore, the turbocharger 20 also includes a drive component 230 and a power switching mechanism 240. The drive component 230 provides power to the first compressor 210 and / or the second compressor 220. The power switching mechanism 240 is switchable between a first operating state and a second operating state. When the power switching mechanism 240 is in the first operating state, the power from the drive component 230 is transmitted to the first compressor 210 and the second compressor 220. When the power switching mechanism 240 is in the second operating state, the power from the drive component 230 is transmitted to the first compressor 210. The main function of the drive component 230 is to provide driving force, and a suitable driving method can be selected based on specific application needs, such as electric motor drive or engine 300 exhaust gas drive.

[0043] When the vehicle is driving in a high-altitude environment, both the cabin 200 and the engine 300 need oxygen supplementation, or only the cabin 200 needs oxygen supplementation. The power switching mechanism 240 can switch to the first working state, and the driving force of the drive component 230 can simultaneously drive the first compressor 210 and the second compressor 220 to work, so that the gas pressurized by the second compressor 220 flows to the cabin 200 through the first flow path 30, and the gas pressurized by the first compressor 210 flows to the engine 300 through the second flow path 40, so as to achieve simultaneous oxygen supplementation for the cabin 200 and the engine 300, which can overcome the high-altitude attenuation of the engine 300 and suppress the high-altitude reaction of the passengers and the driver.

[0044] When only the engine 300 needs oxygen supply, the power switching mechanism 240 can switch to the second working state, and the driving force of the drive component 230 drives the first compressor 210 to work, so that the gas pressurized by the first compressor 210 flows to the engine 300 through the second flow path 40 to achieve oxygen supply to the engine 300.

[0045] Optionally, the first compressor 210 and the second compressor 220 are coaxially arranged, and the power switching mechanism 240 is located between the first compressor 210 and the second compressor 220. For example... Figure 2 As shown, the drive unit 230, the first compressor 210 and the second compressor 220 can be arranged coaxially. By setting the power switching mechanism 240 between the first compressor 210 and the second compressor 220, the structure of the turbocharger 20 can be made compact, which is conducive to the miniaturization design of the turbocharger 20.

[0046] According to some embodiments of the present invention, the vehicle-mounted oxygen supply system 100 further includes a second cooler 90, the second cooler 90 having a first cooling channel 910 and a second cooling channel 920, a first end of the first cooling channel 910 communicating with a second end of the first compressor 210, a second end of the first cooling channel 910 communicating with a first end of the second flow path 40, a first end of the second cooling channel 920 communicating with a second end of the second compressor 220, and a second end of the second cooling channel 920 communicating with a first end of the first flow path 30. Figure 1 and Figure 3As shown, the first cooling channel 910 of the second cooler 90 is located between the first compressor 210 and the second flow path 40, and the second cooling channel 920 of the second cooler 90 is located between the second compressor 220 and the first flow path 30. The first cooling channel 910 and the second cooling channel 920 are independent of each other. Cooling pipes 930 are arranged in the first cooling channel 910 and the second cooling channel 920, and the cooling medium circulating in the cooling pipes 930 is used to cool the high-temperature gas in the first cooling channel 910 and the second cooling channel 920. The high-temperature gas in the first compressor 210 can flow to the engine 300 through the first cooling channel 910 and the second flow path 40. The high-temperature gas in the second compressor 220 can flow to the vehicle compartment 200 through the second cooling channel 920 and the first flow path 30. Thus, by setting the two cooling channels of the second cooler 90 as independent structures, it is possible to ensure that the two high-pressure gases remain completely isolated during the cooling process and avoid gas mixing.

[0047] According to some specific embodiments of the present invention, the first flow path 30 includes an exhaust valve 320, an oxygen generator 330, and an oxygen storage tank 60. The exhaust valve 320 is connected to the second end of the second cooling flow channel 920 and is used to discharge nitrogen. The first end of the oxygen generator 330 is connected to the exhaust valve 320, the inlet of the oxygen storage tank 60 is connected to the second end of the oxygen generator 330, the first outlet of the oxygen storage tank 60 is connected to the first end of the third flow path 50, and the second outlet of the oxygen storage tank 60 is adapted to communicate with the vehicle compartment 200. Figure 1 As shown, the first flow path 30 also includes a pressure relief valve 310, which is located between the second cooler 90 and the exhaust valve 320. When the vehicle compartment 200 requires oxygen supply, the gas in the supply flow path 10 can flow to the second compressor 220, where it is pressurized to become high-temperature, high-pressure gas. This gas is then cooled to medium-temperature, high-pressure gas via the second cooling channel 920 of the second cooler 90 to meet the temperature and pressure requirements of the oxygen generator 330. Before entering the oxygen generator 330, the gas can flow through the pressure relief valve 310 to adjust the pressure appropriately, further optimizing the operating conditions of the oxygen generator 330. Simultaneously, the oxygen generator 330 and the exhaust valve 320 work together to separate oxygen and discharge nitrogen. The oxygen-enriched gas generated by the oxygen generator 330 is stored in the oxygen storage tank 60 and supplied to the vehicle compartment 200 and / or the gas mixer 70 to meet the oxygen requirements of the vehicle compartment 200 and / or the engine 300.

[0048] Thus, the oxygen generator 330 cleverly reuses the turbocharger 20, thereby significantly improving the integration of the vehicle oxygen supply system 100 and effectively reducing costs. The oxygen-enriched gas generated during the oxygen generation process is stored in the oxygen storage tank 60 and supplied to the cabin 200 and the engine 300 respectively as needed.

[0049] Optionally, the oxygen generator 330 can be a molecular sieve type oxygen generator, which generates oxygen through the alternating adsorption and desorption of molecular sieves. Suitable air for molecular sieve operation is obtained by pressurizing filtered air with a compressor and then cooling it through a cooler to obtain medium-temperature, high-pressure gas, typically within the range of 2-3 bar.

[0050] According to some specific embodiments of the present invention, such as Figure 1 As shown, the third flow path 50 includes a first regulating valve 510, the two ends of which are connected to the first outlet of the oxygen storage tank 60 and the second inlet of the gas mixer 70, respectively. By controlling the opening of the first regulating valve 510, the flow rate of oxygen-enriched gas from the oxygen storage tank 60 to the gas mixer 70 can be controlled, thereby controlling the amount of oxygen supplied to the engine 300, ensuring the performance of the engine 300 while avoiding waste of oxygen-enriched gas.

[0051] Optionally, the third flow path 50 also includes a first check valve 520, which is disposed between the first regulating valve 510 and the gas mixer 70 to prevent gas in the gas mixer 70 from flowing back into the oxygen storage tank 60.

[0052] The vehicle-mounted oxygen supply system 100 also includes a second regulating valve 101, a first oxygen concentration sensor 102, and a second oxygen concentration sensor 103. The two ends of the second regulating valve 101 are connected to the second outlet of the oxygen storage tank 60 and the vehicle cabin 200, respectively. The first oxygen concentration sensor 102 is located inside the vehicle cabin 200. The first oxygen concentration sensor 102 detects the oxygen concentration inside the vehicle cabin 200. Based on this oxygen concentration, the opening of the second regulating valve 101 is controlled, thereby controlling the flow rate of oxygen-enriched gas from the oxygen storage tank 60 to the vehicle cabin 200. This satisfies the oxygen needs of passengers while preventing waste of oxygen-enriched gas. The second oxygen concentration sensor 103 is located near the intake system of the engine 300. The second oxygen concentration sensor 103 detects the oxygen concentration in the intake manifold of the engine 300. Based on the oxygen concentration in the intake manifold, it determines whether the engine 300 needs additional oxygen. If additional oxygen is needed, the opening of the first regulating valve 510 is adjusted to control the amount of oxygen supplied to the engine 300.

[0053] Optionally, in order to prevent the intake pressure of the engine 300 from being too high, a bypass valve 104 can be installed on the intake pipe of the engine 300. When the bypass valve 104 is opened, some of the high-temperature gas in the second flow path 40 can be directly discharged to the external environment.

[0054] According to some embodiments of the present invention, the air supply path 10 includes an air handling unit 110 and a distributor 120. The air handling unit 110 is adapted to communicate with the external environment. The distributor 120 includes a first interface 121, a second interface 122, and a third interface 123. The first interface 121 is connected to the air handling unit 110, the second interface 122 is connected to a first flow path 30 via a booster 20, and the third interface 123 is connected to a second flow path 40 via a booster 20. (Refer to...) Figure 1 The air handling unit 110 includes, but is not limited to, filtration devices such as air filters, used to perform pretreatment operations such as filtering and dust removal on the incoming air from the external environment to ensure the air quality of the subsequent vehicle oxygen supply system 100. The distributor 120 can be a three-way valve or other distributor device, and its function is to distribute the gas treated by the air handling unit 110 according to the flow requirements.

[0055] The first interface 121 may be selectively connected to at least one of the second interface 122 and the third interface 123. The connection between the first interface 121 and the second interface 122 forms a first path, and the connection between the first interface 121 and the third interface 123 forms a second path.

[0056] Specifically, after being diverted by the distributor 120, part of the gas flows through the first path to the second compressor 220 of the turbocharger 20, and then through the second cooling channel 920, the pressure relief valve 310, the exhaust valve 320, the oxygen generator 330 and the oxygen storage tank 60 to the vehicle compartment 200; the other part flows through the second path and the second one-way valve 130 to the gas mixer 70. The gas in the gas mixer 70 flows to the first compressor 210 of the turbocharger 20 for pressurization, and then through the first cooling channel 910 and the second flow path 40 to the engine 300.

[0057] like Figure 4 As shown, according to a second aspect embodiment of the present invention, a vehicle control method includes the following: Based on the oxygen supply needs of the vehicle compartment 200 and / or the engine 300, the gas in the supply airflow path 10 is controlled to selectively flow to the first flow path 30 and / or the second flow path 40 via the splitter 120, thereby achieving oxygen supply to the engine 300 and / or the vehicle compartment 200.

[0058] In other words, when the cabin 200 has a need for supplemental oxygen, the gas in the supply airflow path 10 can flow to the second compressor 220 of the supercharger 20. After being pressurized by the second compressor 220, it becomes a high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled and depressurized through the first flow path 30 and becomes oxygen-enriched gas. Finally, the oxygen-enriched gas flows to the cabin 200.

[0059] When the engine 300 has an oxygen supply requirement, the gas in the supply air path 10 can flow to the first compressor 210 of the turbocharger 20. After being pressurized by the first compressor 210, it becomes a high-temperature and high-pressure gas. Then, the high-temperature and high-pressure gas is cooled through the second flow path 40 and flows to the engine 300.

[0060] According to some embodiments of the present invention, if at least one of the cabin oxygen replenishment function and the engine oxygen replenishment function is turned on, or if the cabin oxygen replenishment function and the engine oxygen replenishment function are turned off, the oxygen concentration F1 of the first oxygen concentration sensor 102 and the oxygen concentration F2 of the second oxygen concentration sensor 103 in the vehicle oxygen supply system 100 are obtained, and the vehicle oxygen supply system 100 is the vehicle oxygen supply system 100 according to the first aspect embodiment of the present invention described above.

[0061] Among these options, the vehicle can activate only the cabin oxygen supply function; or, the vehicle can activate only the engine oxygen supply function; or, the vehicle can activate both the cabin oxygen supply function and the engine oxygen supply function simultaneously; or, the vehicle can deactivate both the cabin oxygen supply function and the engine oxygen supply function simultaneously.

[0062] Based on the oxygen concentration F1 of the first oxygen concentration sensor 102 and the oxygen concentration F2 of the second oxygen concentration sensor 103, the operating status of the splitter 120 and the power switching mechanism 240 in the vehicle oxygen supply system 100, as well as the opening degree of the first regulating valve 510 and the second regulating valve 101, are controlled. In other words, the oxygen concentration F1 in the cabin 200 and the oxygen concentration F2 in the intake pipe of the engine 300 can be detected in real time by the first oxygen concentration sensor 102 and the second oxygen concentration sensor 103, as well as the vehicle's starting function (i.e., the aforementioned cabin oxygen replenishment function or engine oxygen replenishment function), to precisely control the operating status of the splitter 120 and the power switching mechanism 240, and simultaneously adjust the opening degree of the first regulating valve 510 and the second regulating valve 101, thereby realizing the dual function of the vehicle oxygen supply system 100, namely, cabin oxygen replenishment function and engine oxygen replenishment function.

[0063] Specifically, when the vehicle simultaneously disables both the cabin oxygen supply function and the engine oxygen supply function, the operating states of the splitter 120 and the power switching mechanism 240, as well as the opening degrees of the first regulating valve 510 and the second regulating valve 101, are controlled based on the oxygen concentration F1 of the first oxygen concentration sensor 102 and the oxygen concentration F2 of the second oxygen concentration sensor 103. The control logic followed by the on-board oxygen supply system 100 at this time is shown in Table 1. When both oxygen concentrations F1 and F2 are within the normal oxygen concentration range of 20.5%-21.5%, the vehicle oxygen supply system 100 does not activate the oxygen replenishment function. At this time, the distributor 120 disconnects the first path (i.e., the first interface 121 and the second interface 122 are not connected), and only the second path (i.e., the first interface 121 and the third interface 123 are connected) is maintained for air intake. The power switching mechanism 240 is in the second working state. When oxygen concentration F1 is in the lower concentration range of 19.5%-20.5%, and oxygen concentration F2 is in the normal oxygen concentration range of 20.5%-21.5%, the vehicle system will remind the user to activate the cabin oxygen replenishment function. At this time, the distributor 120 disconnects the first path, and only the second path is maintained for air intake. The power switching mechanism 240 is in the second working state. If the user chooses to activate it, the current mode will end.

[0064] When oxygen concentration F1 or oxygen concentration F2 is within a low concentration range, the vehicle oxygen supply system 100 will automatically activate the corresponding oxygen replenishment. For example, when oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is less than or equal to 20.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully open, and the opening degree of the second regulating valve 101 is... When oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is between 20.5% and 21.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... When the second regulating valve 101 is fully closed; and the oxygen concentration F1 is between 19.5% and 20.5% and the oxygen concentration F2 is less than or equal to 20.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The opening degree of the second regulating valve 101 is When oxygen concentration F1 is between 20.5% and 21.5% and oxygen concentration F2 is less than or equal to 20.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully closed, and the opening degree of the second regulating valve 101 is... .

[0065] Table 1

[0066] According to some embodiments of the present invention, when only the cabin oxygen replenishment function is activated, the working state of the splitter 120 and the power switching mechanism 240, as well as the opening degree of the first regulating valve 510 and the second regulating valve 101, are controlled based on the oxygen concentration F1 of the first oxygen concentration sensor 102, the oxygen concentration F2 of the second oxygen concentration sensor 103 and the preset oxygen concentration F3.

[0067] Specifically, when the vehicle only activates the cabin oxygen supply function, the user needs to set a preset oxygen concentration F3, which defaults to 21% and has a setting range of 20.5%-23.5%. The control logic followed by the vehicle oxygen supply system 100 is shown in Table 2. When oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is less than or equal to 20.5%, or when oxygen concentration F1 is between 19.5% and 20.5% and oxygen concentration F2 is less than or equal to 20.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully open, and the opening degree of the second regulating valve 101 is... When oxygen concentration F1 is between 20.5% and 21.5% and oxygen concentration F2 is less than or equal to 20.5%, or oxygen concentration F1 is greater than or equal to 21.5% and oxygen concentration F2 is less than or equal to 20.5%, if oxygen concentration F1 is less than or equal to a preset oxygen concentration F3, the distributor 120 opens the first path and the second path, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The opening degree of the second regulating valve 101 is If the oxygen concentration F1 is greater than the preset oxygen concentration F3, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the first regulating valve 510 is fully closed; the opening degree of the second regulating valve 101 is... .

[0068] When oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is between 20.5% and 21.5%, or when oxygen concentration F1 is between 19.5% and 20.5% and oxygen concentration F2 is between 20.5% and 21.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully open, and the second regulating valve 101 is fully closed. When oxygen concentration F1 is between 20.5% and 21.5% and oxygen concentration F2 is between 20.5% and 21.5%, or when oxygen concentration F1 is greater than or equal to 21.5% and oxygen concentration F2 is between 20.5% and 21.5%, if oxygen concentration F1 is less than or equal to a preset oxygen concentration F3, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The second regulating valve 101 is fully closed; if the oxygen concentration F1 is greater than the preset oxygen concentration F3, the distributor 120 disconnects the first path and only maintains the second path for air intake, and the power switching mechanism 240 is in the second working state.

[0069] Table 2

[0070] If the vehicle only activates the engine oxygen replenishment function, the working state of the splitter 120 and the power switching mechanism 240, as well as the opening degree of the first regulating valve 510 and the second regulating valve 101, are controlled according to the preset replenishment level R, the oxygen concentration F1 of the first oxygen concentration sensor 102 and the oxygen concentration F2 of the second oxygen concentration sensor 103.

[0071] Specifically, when the vehicle only activates the engine oxygen supplementation function, the user needs to set a user-defined preset oxygen supplementation level R, which defaults to 10% and has a setting range of 1%-100%. The oxygen supplementation level represents the degree of engine oxygen supplementation and affects the target oxygen concentration in the engine's intake air. The control logic followed by the on-board oxygen supply system 100 is shown in Table 3: When oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is less than or equal to 20.5%, or when oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is between 20.5% and 21.5%, the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The second regulating valve 101 is fully open; when the oxygen concentration F1 is between 19.5% and 20.5% and the oxygen concentration F2 is less than or equal to 20.5%, the oxygen concentration F1 is between 20.5% and 21.5% and the oxygen concentration F2 is less than or equal to 20.5%, the oxygen concentration F1 is between 19.5% and 20.5% and the oxygen concentration F2 is between 20.5% and 21.5%, or the oxygen concentration F1 is between 20.5% and 21.5% and the oxygen concentration F2 is between 20.5% and 21.5%, the distributor 120 opens the first path and the second path, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully closed, and the second regulating valve 101 is fully open.

[0072] When oxygen concentration F1 is less than or equal to 19.5% and oxygen concentration F2 is greater than or equal to 21.5%, if oxygen concentration F2 is less than or equal to (21.5% + 5%R), then the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The opening degree of the second regulating valve 101 is If the oxygen concentration F2 is greater than (21.5% + 5%R), then the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, and the opening degree of the first regulating valve 510 is... The second regulating valve 101 is fully closed.

[0073] When oxygen concentration F1 is between 19.5% and 20.5% and oxygen concentration F2 is greater than or equal to 21.5%, or when oxygen concentration F1 is between 20.5% and 21.5% and oxygen concentration F2 is greater than or equal to 21.5%, if oxygen concentration F2 is less than or equal to (21.5% + 5%R), then the distributor 120 opens the first and second paths, the power switching mechanism 240 is in the first working state, the first regulating valve 510 is fully closed, and the opening degree of the second regulating valve 101 is...

[0075] According to some embodiments of the present invention, when the cabin oxygen replenishment function and the engine oxygen replenishment function are activated simultaneously, the working state of the splitter 120 and the power switching mechanism 240, as well as the opening degree of the first regulating valve 510 and the second regulating valve 101, are controlled according to the preset replenishment level R, the oxygen concentration F1 of the first oxygen concentration sensor 102, the oxygen concentration F2 of the second oxygen concentration sensor 103 and the preset oxygen concentration F3.

[0076] Specifically, when the vehicle simultaneously activates the cabin oxygen supply function and the engine oxygen supply function, a preset oxygen concentration F3 and a preset oxygen supply level R need to be set. The control logic followed by the vehicle oxygen supply system 100 is shown in Table 4: When the oxygen concentration F1 is less than or equal to 19.5% and the oxygen concentration F2 is less than or equal to 20.5%, when the oxygen concentration F1 is less than or equal to 19.5% and the oxygen concentration F2 is between 20.5% and 21.5%, when the oxygen concentration F1 is between 19.5% and 20.5% and the oxygen concentration F2 is less than or equal to 20.5%, or when the oxygen concentration F1 is between 19.5% and 20.5% and the oxygen concentration F2 is between 20.5% and 21.5%, the distributor 120 opens the first path and the second path, the power switching mechanism 240 is in the first working state, and both the first regulating valve 510 and the second regulating valve 101 are fully open.
