Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a vehicle oxygen generation control method, a vehicle oxygen generation system, and a vehicle. Background Technology

[0002] In existing vehicles, the oxygen concentration can easily drop due to the breathing of passengers in a closed environment, leading to problems such as fatigue and lack of concentration. To regulate the oxygen concentration inside the vehicle, passengers usually operate manually, such as turning on the air conditioner to introduce fresh air. However, these manual operation methods pose certain safety risks and lack sufficient intelligence while driving. Therefore, there is an urgent need for an oxygen generation system and oxygen generation control method that can automatically regulate the oxygen concentration inside the vehicle. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the above-mentioned related technologies, and proposes a vehicle oxygen production control method, a vehicle oxygen production system and a vehicle, which can automatically regulate the oxygen concentration inside the vehicle, taking into account both oxygen production and driving safety.

[0004] The solution to the technical problem of this invention is: A vehicle oxygen generation control method, used in conjunction with a vehicle equipped with an oxygen generation unit, the control method comprising: Before the vehicle is driven, obtain the first oxygen concentration value inside the vehicle. When the first in-vehicle oxygen concentration value is lower than the in-vehicle oxygen concentration threshold, the oxygen generating unit is activated until the first in-vehicle oxygen concentration value reaches the in-vehicle oxygen concentration threshold. During vehicle operation, the second in-vehicle oxygen concentration value is obtained: When the second in-vehicle oxygen concentration value is lower than the in-vehicle oxygen concentration threshold, the oxygen generating unit is activated until the second in-vehicle oxygen concentration value reaches the in-vehicle oxygen concentration threshold.

[0005] This technical solution has at least the following beneficial effects: Before passengers drive, the oxygen concentration inside the vehicle is detected, and oxygen is supplied to the vehicle through the oxygen generation unit before driving, ensuring that the oxygen concentration inside the vehicle meets the passenger's needs, reducing the feeling of stuffiness after entering the vehicle, and improving the driving and riding experience. During the vehicle's operation, passengers consume oxygen inside the vehicle through breathing, causing the oxygen concentration to drop. Therefore, the oxygen concentration inside the vehicle is constantly detected. When the oxygen concentration inside the vehicle is detected to be lower than the preset concentration threshold, the oxygen generation unit is immediately activated to supply oxygen to the vehicle, keeping the oxygen concentration inside the vehicle within the normal range and reducing the discomfort of passengers in a low-oxygen state.

[0006] As a further improvement to the above technical solution, and used in conjunction with a remote controller, the method for activating the oxygen generating unit until the first in-vehicle oxygen concentration value reaches the in-vehicle oxygen concentration threshold includes: Before the vehicle is driven, the remote controller is activated, and the vehicle is powered on; Obtain a first distance between the remote controller and the vehicle, and after a first proximity time, obtain a second distance between the remote controller and the vehicle; Based on the first distance, the first approach time, and the second distance, the second approach time of the remote controller reaching the vehicle's location is obtained; During the second proximity time, the power of the oxygen generating unit is adjusted.

[0007] By adopting the above technical solution, firstly, when the remote controller and the vehicle are on the same horizontal plane, the distance between the remote controller and the vehicle is detected. The first distance is the distance between the passenger preparing to board the vehicle and the vehicle. Then, after a preset first approach time, the second distance is subtracted from the first distance to obtain the distance traveled by the passenger during the first approach time. This gives the fastest speed at which the passenger approaches the vehicle. Then, the fastest speed is divided by the first distance to obtain the second approach time estimated by the passenger to reach the vehicle as quickly as possible. The oxygen production speed of the oxygen generating unit is adjusted so that the oxygen produced by the oxygen generating unit during the second approach time can make the oxygen concentration inside the vehicle reach the preset threshold.

[0008] This design allows for an increase in the oxygen supply intensity of the oxygen generator after obtaining the estimated time required for passengers to reach the vehicle. This improves the accuracy of the oxygen generator in adjusting the oxygen concentration inside the vehicle before passengers enter, thereby reducing the time passengers spend waiting for the vehicle to reach the required oxygen concentration.

[0009] As a further improvement to the above technical solution, adjusting the power of the oxygen generating unit includes: The oxygen generating unit includes multiple oxygen generating cells, and the number of oxygen generating cells activated is adjusted.

[0010] By adopting the above technical solution, multiple oxygen generators are installed on the vehicle. When it is necessary to increase the intensity of oxygen output from the oxygen supply unit, more oxygen generators are activated to accelerate the oxygen production power. When it is necessary to maintain the oxygen concentration in the vehicle at a low flow rate, only a small number of oxygen generators need to be activated to supply oxygen to the vehicle interior, thus maintaining a dynamic balance of oxygen concentration in the vehicle interior.

[0011] As a further improvement to the above technical solution, after adjusting the power of the oxygen generating unit: The third distance between the remote controller and the vehicle is reacquired, and after the third proximity time, the fourth distance between the remote controller and the vehicle is acquired. Based on the third distance, the third approach time, and the fourth distance, the fourth approach time of the remote controller reaching the location of the vehicle is obtained; During the fourth proximity time, the power of the oxygen generating unit is adjusted.

[0012] By adopting the above technical solution, after the oxygen supply intensity of the oxygen generating unit is adjusted once, the vehicle continues to measure the third distance between itself and the passengers via the remote controller. After the third approach time, the fourth distance of the passengers is measured, and the passenger's current travel speed is obtained using the calculation method from the previous adjustment. This is used to obtain the fourth approach time of the passengers arriving at the vehicle. By comparison, when the passenger's travel speed increases, the oxygen supply speed of the oxygen generating unit is further increased to ensure that the oxygen concentration inside the vehicle reaches a predetermined threshold when the passengers arrive at the vehicle.

[0013] As a further improvement to the above technical solution, the step of activating the oxygen generating unit when the second in-vehicle oxygen concentration value is lower than the in-vehicle oxygen concentration threshold includes: When the difference between the altitude of the vehicle and the altitude of the predetermined destination is detected to be equal to the altitude difference threshold, the oxygen generation unit is activated.

[0014] As vehicles travel towards higher altitudes, the air becomes thinner, necessitating continuous oxygen supply to achieve the required concentration at that altitude. However, current oxygen supply systems only begin after reaching the destination altitude, resulting in a delay. By employing the aforementioned technical solution, the oxygen supply unit is activated in advance when the difference between the vehicle's current altitude and the destination altitude reaches a threshold, supplying oxygen to the vehicle. This achieves seamless oxygen supply throughout the high-altitude driving process, enhancing driving safety.

[0015] As a further improvement to the above technical solution, the vehicle is equipped with an air purification unit, and the control method further includes: When the detected air pollution level outside the vehicle exceeds the air pollution threshold, the vehicle shuts off the external air circulation and then activates the air purification unit.

[0016] By adopting the above technical solution, when the air quality of the vehicle's surroundings is detected to be poor, the air purification unit is activated to purify the air inside the vehicle, thereby ensuring air health while the vehicle is in motion.

[0017] Secondly, this application also provides a vehicle oxygen generation system, comprising: Oxygen generating unit, which is used to supply oxygen into the vehicle; An air purification unit, used to purify the air inside the vehicle; A control unit, which is electrically connected to the oxygen generating unit and the air purification unit; The control unit is configured to perform a vehicle oxygen production control method as described in the first aspect.

[0018] This technical solution has at least the following beneficial effects: by integrating an oxygen generation unit and an air purification unit inside the vehicle, it is possible to detect and regulate the oxygen concentration and air quality inside the vehicle in a timely manner, thereby improving passenger comfort.

[0019] As a further improvement to the above technical solution, a negative oxygen ion generating unit is also included, which is electrically connected to the control unit.

[0020] By adopting the above technical solution, the negative oxygen ion generating unit can output negative oxygen ions into the vehicle, effectively adsorbing suspended particulate matter, odor molecules and harmful gases in the air, and significantly improving the cleanliness and freshness of the air inside the vehicle.

[0021] As a further improvement to the above technical solution, an air conditioning unit is also included, wherein the oxygen generating unit is electrically connected to the control unit and is installed at the output end of the air conditioning unit.

[0022] By adopting the above technical solution, the oxygen generation unit and the air conditioning unit are integrated to achieve automatic start-up and precise control of the oxygen generation function under different environments. This replaces manual operation under the precise control of the control unit, reducing the safety hazards of operation while driving.

[0023] Thirdly, this application also provides a vehicle equipped with a vehicle oxygen generation system as described in the second aspect.

[0024] This technical solution has at least the following beneficial effects: by setting up an air conditioning oxygen generation system, the air inside the vehicle is regulated, thereby improving passenger comfort. Attached Figure Description

[0031] This application provides a vehicle oxygen production control method, a control system, and a vehicle.

[0032] Firstly, this application provides a vehicle oxygen production control method, referring to... Figure 1 and Figure 2 It includes: S100: Before the vehicle is driven, obtain the first oxygen concentration value inside the vehicle; S200: When the first in-vehicle oxygen concentration value is lower than the in-vehicle oxygen concentration threshold, the oxygen generating unit is activated until the first in-vehicle oxygen concentration value reaches the in-vehicle oxygen concentration threshold. S300: Acquires a second in-vehicle oxygen concentration value while the vehicle is in motion. S400: When the oxygen concentration in the second vehicle is lower than the vehicle oxygen concentration threshold, the oxygen generating unit is activated until the oxygen concentration in the second vehicle reaches the vehicle oxygen concentration threshold.

[0033] As described above, before passengers drive, the oxygen concentration inside the vehicle is detected, and oxygen is supplied to the vehicle through the oxygen generation unit before driving, ensuring that the oxygen concentration inside the vehicle meets the needs of passengers, reducing the feeling of stuffiness after entering the vehicle, and improving the driving and riding experience. During the vehicle's operation, passengers consume oxygen by breathing inside the vehicle, causing the oxygen concentration to drop. Therefore, the oxygen concentration inside the vehicle is constantly monitored. When the oxygen concentration inside the vehicle is detected to be lower than the preset concentration threshold, the oxygen generation unit is immediately activated to supply oxygen to the vehicle, keeping the oxygen concentration inside the vehicle within the normal range and reducing the risk of passengers being in a low-oxygen state.

[0034] Specifically, this control method is used in conjunction with a remote controller. In S100, the specific method for obtaining the first in-vehicle oxygen concentration value before the vehicle starts moving includes: S110: Before the vehicle is driven, passengers such as the driver operate the remote controller to power on and start the vehicle. Then the vehicle starts the internal oxygen detection unit to detect the oxygen concentration in the sealed environment inside the vehicle.

[0035] In the S200, the methods for activating the oxygen generation unit until the first in-vehicle oxygen concentration reaches the in-vehicle oxygen concentration threshold include: S210: Obtain the distance between the location of the remote controller and the vehicle, obtain the first distance between the location of the passenger and the vehicle, and after the first approach time, obtain the second distance between the location of the remote controller and the vehicle, that is, obtain the second distance between the location of the passenger and the vehicle. S220: Based on the first distance, the second distance, and the first approach time, the moving speed of the remote controller during the process of the passenger arriving at the vehicle location is obtained. Specifically, the first distance is subtracted from the second distance to obtain the passenger's moving distance. The passenger's moving distance is divided by the first approach time to obtain the passenger's first moving speed during this process. The first distance and the first moving speed are divided to obtain the second approach time of the remote controller arriving at the vehicle location. The second approach time is the estimated shortest time for the passenger to arrive at the vehicle location. S230: After the control unit in the vehicle calculates the second approach time, it starts the oxygen generation unit and adjusts the output power of the oxygen generation unit within the second approach time.

[0036] Specifically, the method for adjusting the output power of the oxygen generating unit is as follows: S231: When the oxygen concentration in the vehicle interior output by the oxygen generating unit is lower than the vehicle interior oxygen concentration threshold during the second proximity time, increase the output power of the oxygen generating unit.

[0037] S232: When the oxygen concentration output by the oxygen generating unit in the second proximity time is higher than the oxygen concentration threshold in the vehicle, maintain the current output power of the oxygen generating unit until the oxygen concentration value in the vehicle reaches the oxygen concentration threshold in the vehicle.

[0038] By adopting the above technical solution, firstly, when the remote controller and the vehicle are on the same horizontal plane, the distance between the remote controller and the vehicle is detected. The first distance is the distance between the passenger preparing to board the vehicle and the vehicle. Then, after a preset first approach time, the second distance is subtracted from the first distance to obtain the distance traveled by the passenger during the first approach time. This gives the fastest speed at which the passenger approaches the vehicle. Then, the fastest speed is divided by the first distance to obtain the second approach time estimated by the passenger to reach the vehicle as quickly as possible. The oxygen production speed of the oxygen generating unit is adjusted so that the oxygen produced by the oxygen generating unit during the second approach time can make the oxygen concentration inside the vehicle reach the preset threshold.

[0039] This design allows for an increase in the oxygen supply intensity of the oxygen generator after obtaining the estimated time required for passengers to reach the vehicle. This improves the accuracy of the oxygen generator in adjusting the oxygen concentration inside the vehicle before passengers enter, thereby reducing the time passengers spend waiting for the vehicle to reach the required oxygen concentration. This enables passengers and the driver to start driving quickly.

[0040] In this embodiment, the oxygen generating unit includes multiple oxygen generating cells. The specific method for adjusting the power of the oxygen generating unit includes: adjusting the number of oxygen generating cells that are activated. As can be seen from steps S231 and S232, when it is necessary to increase, decrease or turn off the power of the oxygen generating unit, it is only necessary to increase, decrease or turn off a certain number of oxygen generating cells to change the output of the entire oxygen generating unit.

[0041] As can be seen from the above, by installing multiple oxygen generators in the vehicle, when it is necessary to increase the intensity of oxygen output from the oxygen supply unit, more oxygen generators are activated to accelerate the oxygen production power. When it is necessary to maintain the oxygen concentration in the vehicle at a low flow rate, only a small number of oxygen generators need to be activated to supply oxygen to the vehicle interior, thus maintaining a dynamic balance of oxygen concentration in the vehicle interior.

[0042] Because passengers may increase their speed during movement, in order to make a secondary correction to the arrival time of passengers and the driver, and thus complete the correction of the oxygen supply speed inside the vehicle before the passengers arrive, in this embodiment, after step S230, the following is also included: S240: Reacquire the third distance between the remote controller and the vehicle. After the third proximity time, acquire the fourth distance between the remote controller and the vehicle. This will give you the third distance between the passenger or driver and the vehicle and the fourth distance between the passenger or driver and the vehicle after the third proximity time. Based on the third distance, the third approach time, and the fourth distance, the fourth approach time for the remote controller to reach the vehicle's location is obtained. Specifically, the distance the remote controller moves within the third approach time is obtained based on the difference between the third distance and the fourth distance, which is the distance the passenger or driver moves within the third approach time. The ratio between the third approach time and this moving distance is used as the passenger's moving speed. The ratio between the third distance and this moving speed is used to obtain the fourth approach time. The fourth approach time is the shortest time required for the passenger or driver to move from the third distance to the vehicle. During the fourth approach time, the power of the oxygen generating unit is adjusted to ensure that the oxygen concentration inside the vehicle is adjusted before passengers or the driver arrives, reducing the waiting time for passengers and the driver.

[0043] Specifically, in S240, the method for adjusting the power of the oxygen generating unit is the same as the method for adjusting it in step S230.

[0044] As described above, after the oxygen supply intensity adjustment of the oxygen generating unit is completed, the vehicle continues to measure the third distance between itself and the passengers via the remote controller. After the third approach time, the fourth distance of the passengers is measured, and the passenger's current speed is obtained using the calculation method from the previous adjustment. This is used to obtain the fourth approach time of the passengers arriving at the vehicle. By comparison, the output power of the oxygen generating unit is dynamically corrected. When the passenger's speed increases, the oxygen supply speed of the oxygen generating unit is further increased to ensure that the oxygen concentration inside the vehicle reaches a predetermined threshold when the passengers arrive.

[0045] In some embodiments, activating the oxygen generating unit when the second in-vehicle oxygen concentration value is lower than the in-vehicle oxygen concentration threshold includes: When the difference between the vehicle's altitude and the altitude of the predetermined destination is equal to the altitude difference threshold, the oxygen generation unit is activated to supply oxygen into the vehicle until the oxygen concentration inside the second vehicle reaches the vehicle oxygen concentration threshold.

[0046] As a vehicle travels towards higher altitudes, the air becomes thinner with increasing altitude, necessitating continuous oxygen supply to the vehicle to achieve the required oxygen concentration at that altitude. However, current oxygen supply systems only begin after reaching the destination altitude, resulting in a delay. By adopting the aforementioned technical solution, based on navigation data, the oxygen supply unit is activated in advance when the difference between the vehicle's current altitude and the destination altitude reaches a threshold, supplying oxygen to the vehicle. This achieves seamless oxygen supply throughout the high-altitude driving process, improving driving safety.

[0047] In some embodiments, an air purification unit is installed on the vehicle, and the control method further includes: When the detected air pollution level outside the vehicle exceeds the air pollution threshold, the vehicle shuts off the external air circulation and then activates the air purification unit.

[0048] By adopting the above technical solution, when the air quality of the vehicle's surroundings is detected to be poor, the air purification unit is activated to purify the air inside the vehicle, thereby ensuring air health while the vehicle is in motion.

[0049] Secondly, this application also provides a vehicle oxygen generation system for use in conjunction with a vehicle, the vehicle oxygen generation system comprising: The in-vehicle oxygen detection unit is used to detect the oxygen concentration inside the vehicle. Oxygen generating unit, used to produce oxygen for the vehicle interior; An air quality detection unit is used to detect the air quality in the environment where the vehicle is located. An air purification unit, used to purify the air inside a vehicle; Altitude detection unit, used to detect the altitude of the vehicle; The control unit is electrically connected to the in-vehicle oxygen detection unit, oxygen generation unit, air detection unit, air purification unit, and altitude detection unit. The control unit is configured to perform a vehicle oxygen production control method as described in the first aspect.

[0050] Furthermore, it also includes a negative oxygen ion generating unit, which is electrically connected to the control unit. By adopting the above technical solution, the negative oxygen ion generating unit can output negative oxygen ions into the vehicle, effectively adsorbing suspended particulate matter, odor molecules and harmful gases in the air, and significantly improving the cleanliness and freshness of the air inside the vehicle.

[0051] Specifically, in high-altitude scenarios, the negative oxygen ion generator is turned off, and the oxygen generation unit is activated according to the altitude change. In low-altitude scenarios, the control unit can first activate the air purification unit to purify the air in the vehicle based on the detection data of the air detection unit, and then activate the negative oxygen ion generator after the pollutant concentration drops.

[0052] Furthermore, the oxygen generation unit includes multiple oxygen generator units, and the vehicle also includes an air conditioning unit. The oxygen generator units are installed at the output end of the air conditioning unit. By integrating the oxygen generation unit and the air conditioning unit, the automatic start and stop and precise control of the oxygen generation function under different environments can be achieved. Thus, under the precise control of the control unit, manual operation can be replaced, reducing the safety hazards of operation while driving.

[0053] Furthermore, the control unit has multiple preset driving scenario parameter groups, each of which corresponds to calibrable parameters such as altitude, oxygen concentration target range, and negative oxygen ion output intensity. After passengers switch scenario modes via the vehicle system or voice, the control unit automatically calls the corresponding scenario parameter group to complete the corresponding parameter matching.

[0054] Furthermore, it also includes a personnel detection unit capable of detecting the number of people inside the vehicle. When the oxygen concentration inside the vehicle is in dynamic equilibrium, the control unit can dynamically adjust the output power of the oxygen generating unit based on the occupant number detection results.

[0055] Thirdly, this application also provides a vehicle equipped with a vehicle oxygen generation system as provided in the second aspect of this application, so as to regulate the oxygen concentration inside the vehicle.
