[0047] In order to enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0049] In an embodiment of the present invention, a vehicle system with an on-vehicle oxygen generation system is provided. As Figure 1 shown, the vehicle system includes an air suspension system and an on-vehicle oxygen generation system. The following will separately describe the two component systems in detail:

[0050] As Figure 1As shown in the figure, the on-vehicle oxygen generation system includes a housing, a molecular sieve and an oxygen storage tank arranged in the housing. The on-vehicle oxygen generation system further includes: an air inlet interface and an air duct. The gas discharged from the air inlet interface passes through the molecular sieve, which can adsorb nitrogen in the air under pressurized conditions, and allow oxygen to pass through and be enriched in the oxygen storage tank; the outlet of the oxygen storage tank is connected to the inlet end of the air duct, and the other end of the air duct, i.e., the outlet end, is communicated with the vehicle cockpit outside the housing of the on-vehicle oxygen generation system, and the opening or closing of the oxygen outlet channel can be controlled by a controllable electronic valve. Specifically, the electronic valve can be arranged in any area of the oxygen outlet channel after the outlet of the oxygen storage tank, such as directly arranged at the outlet of the oxygen storage tank or any position on the air duct. The outlet end of the air duct is connected to the air outlet of the vehicle air conditioner, and / or, the air duct extends to the cockpit and / or the vehicle trunk through an extension pipe.

[0051] As Figure 1 shown in the figure, the air suspension system includes an air compressor, an air suspension air tank, an air spring assembly and a shock absorber. Among them, the air suspension air tank is configured to store the gas compressed by the air compressor; in this embodiment, the air suspension air tank is configured with a first outlet and a second outlet. The first outlet is communicated with the air inlet interface of the on-vehicle oxygen generation system, and the second outlet is respectively connected to the air spring assembly and the shock absorber through a pneumatic distribution valve.

[0052] On the one hand, the high-pressure gas stored in the air suspension air tank can provide power for the air spring assembly (air spring) and the shock absorber, ensuring that the air suspension system can quickly respond to the adjustment requirements of the vehicle body height. The air suspension air tank can balance the air pressure in the air suspension system, avoid the unstable operation of the air spring caused by air pressure fluctuations, and the air suspension air tank can also play an emergency reserve function in the case that the air compressor cannot work properly for a short time to maintain the basic driving function of the vehicle.

[0053] On the other hand, the air suspension air tank provides an oxygen source for the on-vehicle oxygen generation system, that is, the first outlet of the air suspension air tank is connected to the air inlet interface of the on-vehicle oxygen generation system to supply gas to the molecular sieve; in this embodiment, the on-vehicle oxygen generation system is provided with two molecular sieve adsorption towers. When one of the molecular sieve adsorption towers reaches saturation in adsorbing nitrogen, the oxygen generation system will switch to the other molecular sieve adsorption tower, and at the same time, perform a decompression operation on the saturated molecular sieve adsorption tower to desorb and discharge the adsorbed nitrogen. The double molecular sieve adsorption structure can not only efficiently separate high-purity oxygen from the air, but also realize continuous oxygen supply.

[0054] In an embodiment of the present invention, at least one of the following gas purification designs is also made:

[0055] Design 1: The air compressor of the air suspension system adopts an oil-free lubrication structure;

[0056] Design 2: A purifier and an oil separator are arranged on the input side or the output side of the air compressor. The purifier purifies the gas before or after compression by the air compressor, such as removing moisture, dust, and other impurities in the gas, and the oil separator removes oil from the gas before or after compression by the air compressor;

[0057] Design 3: A purifier and an oil separator are arranged between the air inlet interface of the on-vehicle oxygen generation system and the molecular sieve. The purifier purifies the gas to be delivered to the molecular sieve, such as removing moisture, dust, and other impurities in the gas, and the oil separator removes oil from the gas to be delivered to the molecular sieve.

[0058] In a specific embodiment, the on-vehicle oxygen generation system further includes a vacuum pump arranged in the housing. When the humidity in the on-vehicle oxygen generation system reaches a certain level, the vacuum pump is started to discharge the moisture in the housing to the vehicle exhaust pipe outside the housing.

[0059] Based on the above vehicle system, this embodiment provides an on-vehicle oxygen generation control system, as Figure 2 shown, including a controller, multiple sensors, and a parameter setting module. The parameter setting module outputs target oxygen generation parameters to the controller;

[0060] The input end of the controller is electrically connected to the sensor, and the output end of the controller is connected to the air compressor of the air suspension system and the electronic valve at the air duct of the on-vehicle oxygen generation system.

[0061] The controller controls the opening and closing of the air compressor and the electronic valve at the air duct according to the target oxygen generation parameters and / or the detection results of the sensor.

[0062] As Figure 3 shown, this embodiment provides an on-vehicle oxygen generation control method, including the following steps:

[0063] When the oxygen generation condition is met, it is judged whether the air suspension system is in operation, or it is judged whether the vehicle air conditioning system is in operation and the temperature adjustment has not been completed; if so, the operation of the on-vehicle oxygen generation system is temporarily stopped;

[0064] When the oxygen generation condition is met, if the air suspension system is not in operation and the air conditioning system has not been started or the temperature adjustment has been completed, the oxygen storage tank of the on-vehicle oxygen generation system is controlled to release oxygen.

[0065] This embodiment makes a new configuration optimization based on the air compressor and air storage tank of the existing vehicle air suspension system, and realizes the oxygen generation function on the basis of protecting the original air suspension function of the system. In terms of oxygen generation control, it is necessary to give priority to ensuring the safety driving function of the vehicle air suspension system, followed by giving priority to adjusting the temperature and comfort of the air conditioner, then considering adjusting the appropriate oxygen concentration, and finally considering the dehumidification and drying of the oxygen generation system.

[0066] Specifically, if any one or more of the following conditions are met, the oxygen generation condition is satisfied:

[0067] Using a sensor to detect the oxygen concentration in the cockpit, and its detected value is lower than a preset first concentration threshold;

[0068] And / or, using a sensor to detect the oxygen concentration in the driving environment outside the vehicle, and its detected value is lower than a preset second concentration threshold;

[0069] And / or, using a sensor to detect the facial information of the driver, and then calculating that the blink frequency of the driver is lower than a preset blink frequency threshold;

[0070] And / or, using a sensor to detect the heart rate of the driver, and its detected value reaches a preset heart rate threshold, or, then calculating that the heart rate increase amplitude reaches a preset heart rate increase threshold.

[0071] In another embodiment of the present invention, the vehicle-mounted oxygen generation control system integrates an AI model;

[0072] Obtain driver characteristic information, which includes one or more of height, weight, gender, current blood oxygen concentration, heart rate, dressing index, current driving position image; and / or, obtain cockpit environment characteristic information, which includes one or more of temperature information, oxygen concentration information, humidity information;

[0073] Input the driver characteristic information and / or cockpit environment characteristic information into the AI model;

[0074] The AI model generates an oxygen generation plan, which includes the oxygen generation rate;

[0075] According to the oxygen generation plan generated by the AI model, control the opening degree of the electronic valve at the air duct: the greater the oxygen generation rate, the greater the opening degree of the electronic valve at the air duct.

[0076] If a user's oxygen generation adjustment instruction is monitored, adjust the opening degree of the electronic valve at the air duct according to the oxygen generation adjustment instruction, and optimize and train the AI model according to the adjusted oxygen generation plan and the input quantity of the AI model.

[0077] In one embodiment, the control method further includes: identifying the identity information of the driver, storing the corresponding oxygen generation scheme closest to him in the database, and mapping and associating it with the driver's identity;

[0078] The control method further includes: identifying the identity of the current driver, and searching for the associated oxygen generation scheme in the database; if the query is successful, execute the queried oxygen generation scheme; if the query fails, use the AI model to generate the corresponding oxygen generation scheme and execute it.

[0079] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0080] The above are only specific embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
