[0037] In step S104, the scene in which the vehicle is currently located is determined based on the driving state information.
[0038] In the technical solution provided in step S104 of the embodiments of the present application, the scene can be various types of driving scenes, including but not limited to normal operation scenes, collision scenes, and water falling scenes.
[0039] In the embodiments of the present application, after the driving state information of the vehicle is acquired, the scene in which the vehicle is currently located can be determined based on the driving state information.
[0040] Optionally, the water pressure change information, the acceleration change information, the airbag collision signal, and the door state signal acquired above are compared with a series of preset thresholds (such as a water pressure threshold), and a comparison result is obtained. The comparison result obtained by comparing the current driving state information of the vehicle with the thresholds of different scenes can be used to determine the scene in which the vehicle is currently located.
[0041] In the embodiments of the present application, the different driving scenes of the vehicle, including normal driving, collision, and water falling, can be identified by the above method, thereby providing a basis for subsequent decision-making. By automatically distinguishing and judging different conditions faced by the vehicle, the safety performance of the vehicle is further improved.
[0042] In step S106, in response to the scene being a first type of scene, the gas supply system is controlled to store a first gas in the environment in which the vehicle is located by using the electric energy of the vehicle.
[0043] In the technical solution provided in the step S106 of the embodiment of the present application, the first type of scenario can be used to represent a normal running scenario in which the vehicle is located. The electric energy can be surplus electric energy used to maintain the normal running of the vehicle, and the gas supply system can be a system for providing oxygen for the driver and passengers of the vehicle in the first type of scenario. The first gas can be a gas with the characteristic of being easily decomposed into oxygen, for example, the first gas is ozone (O3).
[0044] Optionally, when it is detected that the sensor signals in the collected driving state information and the signals obtained by the acquisition device are normal, it can be determined that the vehicle is currently in a normal running scenario, that is, the vehicle is currently in a first type of scenario. When the vehicle is in the first type of scenario, the electric energy of the vehicle can be used to control the gas supply system to suck in external air and perform pretreatment such as drying and filtering to remove impurities in the external air, so as to obtain pretreated external air.
[0045] Optionally, the pretreated external air is further prepared, for example, high-purity second gas is separated and obtained from the pretreated external air by a pressure swing adsorption (PSA) method. Further, the high-concentration second gas can be converted into the first gas, such as ozone, by high-voltage discharge.
[0046] Optionally, the generated first gas is delivered to a pre-prepared storage container, and the adsorbent (such as modified activated carbon, metal oxide, etc.) filled in the storage container can efficiently adsorb ozone molecules to realize stable storage of ozone at normal temperature and pressure, so as to ensure high-density storage and long-term safety and stability of ozone.
[0047] In the embodiment of the present application, the surplus electric energy generated by the engine and the battery can be fully utilized to prepare the first gas in advance, which provides a guarantee for possible emergency situations.
[0048] In the technical solution provided in the step S108 of the embodiment of the present application, the second type of scenario can be used to represent a dangerous scenario, such as a collision scenario and a water landing scenario.
[0049] In the technical solution provided in the step S106 of the embodiment of the present application, the first type of scenario can be used to represent a normal running scenario in which the vehicle is located. The electric energy can be surplus electric energy used to maintain the normal running of the vehicle, and the gas supply system can be a system for providing oxygen for the driver and passengers of the vehicle in the first type of scenario. The first gas can be a gas with the characteristic of being easily decomposed into oxygen, for example, the first gas is ozone (O3).
[0050] Optionally, based on the stored first gas, when it is determined that the vehicle is currently located in a second type of scenario, the gas supply system is controlled to convert the first gas into the second gas.
[0051] Optionally, when the collected driving state information includes a continuously rising water pressure, an activated airbag, or an abnormal door state signal, it can be determined that the vehicle is currently in a dangerous scenario, i.e., a second type of scenario.
[0052] Optionally, the gas supply system can convert the ozone (which can also be referred to as a first gas) in the storage container into oxygen (which can also be referred to as a second gas) quickly by heating or introducing a catalyst.
[0053] Optionally, during the conversion of ozone into oxygen, the gas supply system can continuously monitor the decomposition efficiency of ozone, the purity and delivery of oxygen, and adjust the heating temperature or the amount of catalyst in real time to ensure the rapidity and safety of the oxygen supply process.
[0054] Optionally, the generated oxygen can be further treated to remove any harmful substances that may remain.
[0055] In the embodiments of the present application, the above method can quickly and efficiently convert the pre-stored ozone in the storage container into oxygen when the vehicle is in a dangerous scenario, thereby improving the practicality of the oxygen supply system.
[0056] Step S110: Control the gas supply system to release the second gas to at least one occupant.
[0057] In the technical solution provided by step S110 in the embodiments of the present application, the occupant can refer to a vehicle occupant, including a driver and other vehicle occupants.
[0058] Optionally, after the first gas is converted into the second gas, the gas supply system can execute a preset oxygen supply mechanism. In the embodiments of the present application, the oxygen supply mechanism can start the oxygen mask supply function in the vehicle, quickly eject the oxygen mask to a range that the occupant can reach, so that the occupant can wear and use it; the gas supply system releases the second gas (such as oxygen) to the occupant through the oxygen mask.
[0059] Optionally, during the release of the second gas, the gas supply system can continuously monitor the delivery of the second gas to ensure the continuity and stability of the second gas.
[0060] In the step S102 to the step S110 of the embodiment of the present application, the driving state information of the vehicle is acquired, wherein the driving state information is used to represent the state of the vehicle in the driving process; in response to the scene being the first type scene, the air supply system is controlled to store the first gas in the environment where the vehicle is located by using the electric energy of the vehicle; in response to the scene being the second type scene, the air supply system is controlled to convert the first gas into the second gas, wherein the storage difficulty of the second gas is higher than the storage difficulty of the first gas, and the dangerous degree of the second type scene to at least one occupant in the vehicle is greater than the dangerous degree of the first type scene to the at least one occupant; the air supply system is controlled to release the second gas to the at least one occupant. That is to say, in the embodiment of the present application, the first gas in the ambient air is collected when the vehicle is in the first type scene, and the first gas is converted into the second gas for storage; when the vehicle is in the second type scene, the stored first gas is converted into the second gas and released to the occupant.

[0061] The embodiment of the present application will be described in detail below in combination with the above steps.
[0062] As an optional implementation, the driving state information of the vehicle is acquired, including: in the driving process of the vehicle, a plurality of driving state detection devices arranged on the vehicle are used to acquire a plurality of driving state information; and based on the driving state information, the scene where the vehicle is currently located is determined, including: according to a plurality of state conditions respectively met by the plurality of driving state information, the scene is determined.
[0063] In the embodiment of the present application, the driving state detection device can include but is not limited to various sensors of the vehicle, such as water pressure sensors arranged on the bottom and side of the vehicle, vehicle body acceleration sensors, and acquisition devices of CAN bus information of the vehicle, etc. The state condition can be used to represent a preset condition required to be met by the driving state information when the scene is determined based on the series of driving state information. For example, the threshold of the water pressure change information detected by the water pressure sensor, the threshold of the acceleration change information detected by the vehicle body acceleration sensor (including the horizontal acceleration change information and the vertical acceleration change information of the vehicle), the door state acquired by the CAN bus information acquisition device, and whether there is an airbag collision signal in the driving state information, etc.
[0064] In the embodiment of the present application, the scene where the vehicle is currently located can be determined by at least one driving state detection device and the driving state information acquired by the driving state detection device.
[0065] Optionally, the sensor signal of the water pressure sensor in the driving state information, i.e., the water pressure change information obtained by continuously measuring the environment around the vehicle, is taken as one of the decision factors for the scene judgment.
[0066] Optionally, the acceleration sensor signal in the driving state information, i.e., the acceleration change information in the vertical and horizontal directions of the vehicle, is taken as one of the decision factors for the scene judgment.
[0067] Optionally, based on the airbag collision signal and the door state signal obtained by the CAN bus information acquisition device, it is judged whether the airbag is activated and whether the door is intact, and the airbag collision signal and the door state signal can be taken as one of the decision factors for the scene judgment.
[0068] Optionally, the above-mentioned series of decision factors that can be used for scene judgment are compared with the corresponding scene preset conditions, and the comparison results are obtained, and the current scene of the vehicle can be determined based on the comparison results. In the embodiment of the application, the comparison results can be used to represent whether the water pressure change information, the acceleration change information, the airbag collision signal, and the door state signal meet the corresponding scene preset conditions, and the number of preset conditions that are met.
[0069] Optionally, if there is no sensor signal in the driving state information that is abnormal, it can be judged that the vehicle is in a normal running scene.
[0070] In the embodiment of the application, the above-mentioned method can effectively identify the normal running, falling into water, and collision of the vehicle, and provide basic information support for subsequent decision-making.
[0071] As an optional implementation, the driving state detection device includes at least one pressure sensor, an acceleration sensor, and a bus information acquisition device on the vehicle, and the driving state information includes pressure information, acceleration information, and bus information. During the driving of the vehicle, a plurality of driving state detection devices deployed on the vehicle are used to obtain a plurality of driving state information, at least including two of the following: during the driving of the vehicle, the pressure sensor is used to obtain pressure information, wherein the pressure information is used to represent the degree of extrusion of the vehicle by a target object in a scene and the danger level of the target object affecting the scene; during the driving of the vehicle, the acceleration sensor is used to obtain acceleration information, wherein the acceleration information is used to represent the degree of change of the driving state of the vehicle during driving; and during the driving of the vehicle, the bus information acquisition device is used to obtain bus information, wherein the bus information is used to represent the safety level of the vehicle.
[0072] In the embodiments of the present application, the pressure sensor can be a water pressure sensor, and the pressure information can be used to represent the degree of compression of the vehicle by the target object in the scene and the degree of danger of the target object affecting the scene. The acceleration information can be used to represent the degree of change in the driving state of the vehicle during driving. The bus information can be used to represent the safety degree of the vehicle. The target object can be water. The bus information can be used to represent CAN bus information, such as an airbag collision signal, a vehicle door state signal, and the like. In the embodiments of the present application, the pressure information can also be referred to as pressure change information, and the acceleration information can also be referred to as acceleration change information.
[0073] Optionally, the pressure information of the target object on the vehicle is continuously read by the water pressure sensors installed on the bottom and sides of the vehicle. For example, the water pressure sensor on the bottom of the vehicle can monitor the instantaneous pressure change when the vehicle contacts the water surface in real time. When the vehicle falls into the water body, the water pressure will increase rapidly. If the water pressure rises above a certain preset threshold within a short period of time, it can be preliminarily judged that the vehicle may have fallen into the water.
[0074] Optionally, the acceleration information of the vehicle in the horizontal and vertical directions is continuously monitored and obtained by the acceleration sensor of the vehicle. For example, the vertical direction acceleration monitoring can capture the deceleration (close to the earth's surface gravity acceleration) of the vehicle during free fall and the rebound acceleration after touching the water.
[0075] Optionally, the airbag state, the vehicle door lock state, the engine fault signal, the battery voltage information, and the vehicle body inclination angle information are obtained in real time by the CAN bus information acquisition device. The airbag state includes whether the airbag has been deployed, whether the pressure of the airbag is normal or whether there is a leakage sign, etc. The vehicle door lock state includes monitoring whether the vehicle door is locked or unlocked, and whether there is a signal of the vehicle door being opened. The engine fault signal includes checking whether the engine has a fault or an abnormal condition, such as overheating, low engine oil pressure, etc. The battery voltage information includes monitoring the battery voltage of the vehicle. The vehicle body inclination angle information includes the current vehicle body inclination angle of the vehicle.
[0076] In the embodiments of the present application, the driving state of the vehicle can be monitored and analyzed in real time, comprehensively and accurately by the above method, so as to realize the identification and judgment of the scene in which the vehicle is located.
[0077] As an optional implementation, the scene is determined according to a plurality of state conditions respectively satisfied by a plurality of driving state information, including: in response to at least two driving state information in the plurality of driving state information satisfying at least two corresponding state conditions, determining that the scene is a second type of scene; and in response to at most one driving state information in the plurality of driving state information satisfying at most one corresponding state condition, determining that the scene is a first type of scene.
[0078] In the embodiments of the present application, the above-mentioned air supply system is started only when multiple state conditions are met simultaneously, that is, only when multiple state conditions are met simultaneously, it can be indicated that the vehicle is in a dangerous scene such as falling into water, if only one state condition is met, or none of them is met, it indicates that the vehicle is in a normal driving scene.
[0079] Optionally, the vehicle is determined to be in a dangerous scene such as a falling into water scene or a collision scene through at least two different types of sensor data or vehicle state information. For example, if the water pressure sensor shows that the water pressure rises rapidly above a preset threshold, the vehicle body acceleration sensor detects acceleration information close to the vertical direction of free fall, and the airbag collision signal is triggered, it can be determined that the scene is a second type of scene.
[0080] Optionally, when only the water pressure sensor detects a slight change in water pressure, and there is no information support from other sensors (such as no abnormal acceleration and no airbag triggering), it can be considered that the vehicle is in a first type of scene of "light wading" or "normal driving".
[0081] Optionally, when only the acceleration sensor detects an abnormal acceleration in the vertical direction, and there is no information support from other sensors, considering that the vehicle may encounter various scenes, such as driving on uneven road surface, emergency braking or sudden acceleration, etc., which may cause the acceleration sensor to capture abnormal signals. In the above-mentioned scene, the air supply system can consider that the vehicle has a potential false triggering condition. The air supply system will further monitor the signals of other sensors such as the water pressure sensor to confirm whether there is an actual falling into water scene. If there is no corresponding sensor signal from other sensors within a certain time, the exhaust system remains in the judgment of the first type of scene.
[0082] Optionally, when only the bus information is abnormal, and there is no information support from other sensors, it can be considered that there is a problem with an electronic system or device inside the vehicle, and the vehicle is not necessarily in a second type of scene. For example, the bus information anomaly may be caused by software errors, communication interference or other electronic device failures. The exhaust system will further monitor the signals of other sensors and cross-verify with other sensor signals to determine whether to start the air supply system. If only the bus information is abnormal, and there is no other abnormality, the exhaust system continues to remain in the judgment of the first type of scene to avoid false start.

[0084] As an optional implementation, in response to the scene being a first type of scene, the air supply system is controlled to store a first gas in an environment in which the vehicle is located using electrical energy of the vehicle, including: in response to the scene being a first type of scene, the air supply system is controlled to prepare a second gas from the environment using electrical energy; the air supply system is controlled to convert the second gas into the first gas; and the first gas is stored in the air supply system.
[0085] Optionally, impurities such as dust and particulate matter in the air are removed by an air filter in the air supply system; a high-concentration second gas (such as oxygen) can be separated from compressed air by pressure swing adsorption (PSA) or membrane separation technology. The separated second gas can be sent to an ozone generator; by using the above-mentioned ozone generator, the separated second gas is converted into a first gas (such as ozone) by methods such as corona discharge or ultraviolet irradiation. In the embodiments of the present application, the above-mentioned method can be implemented based on the excess electrical energy of the vehicle (such as that generated during engine operation). For example, the excess electrical energy generated by the engine of the vehicle during operation can be monitored in real time by the air supply system, and when sufficient power reserves are detected, the air supply system will automatically start the above-mentioned oxygen preparation and storage process without affecting the normal power demand of the vehicle.
[0086] Optionally, when the air supply system detects a dangerous scene such as falling into water and needs to provide air supply support immediately, the conversion device in the air supply system can heat or use a catalyst to rapidly decompose the second gas into the first gas.

[0088] In the embodiments of the present application, the above-mentioned method can achieve effective use of resources, and at the same time avoid the safety hazards that may be caused by conventional high-pressure storage. Rapid decomposition of the stored second gas into the first gas by heating or the action of a catalyst can ensure that the required life support gas can be provided quickly in an emergency, thereby saving valuable escape and rescue time for the occupants.

[0090] In the embodiments of the present application, the adsorption module can be used to represent a gas storage device, which is filled with materials with high adsorption performance, such as silica gel, activated carbon, etc., to adsorb and store the second gas (such as ozone) in normal driving scenarios. The cooling module can be used to represent a cooling system, which can reduce the temperature of the second gas to a specific temperature threshold, thereby liquefying the second gas. The temperature threshold can be used to represent the minimum temperature required to convert the gas from a normal temperature state to a liquefied state.
[0091] Optionally, high-density and low-risk safe storage can be achieved by adsorbing on a specific adsorbent (such as silica gel, activated carbon) or in a liquid state at low temperature.
[0092] Optionally, the prepared second gas is transmitted to the adsorption module through a pipeline; after the second gas enters the adsorption module, it is in contact with materials with high adsorption performance, such as silica gel, activated carbon, etc. The material captures and fixes the molecules of the second gas through a large number of micropores on the surface of the material, thereby achieving the purpose of storing the second gas.
[0093] Optionally, the prepared second gas can also be input into the cooling module for cooling by a refrigerant inside the cooling module. The refrigerant can be freon, ammonia water, or other suitable cooling medium. The cooling module can cool the second gas to a pre-set temperature threshold, such as -111°C, to ensure that the second gas can be liquefied; the liquefied second gas can be transferred to a liquefied gas storage tank through a dedicated low-temperature pipeline for storage. The gas storage tank is designed with a thermal insulation layer to maintain a low-temperature environment and prevent gasification caused by external heat.

[0095] In the embodiment of the present application, the driving state information of the vehicle is obtained by the above method, wherein the driving state information is used to represent the state of the vehicle in the driving process; in response to the scene being the first type of scene, the gas supply system is controlled to store the first gas in the environment in which the vehicle is located by using the electric energy of the vehicle; in response to the scene being the second type of scene, the gas supply system is controlled to convert the first gas into the second gas, wherein the storage difficulty of the second gas is higher than the storage difficulty of the first gas, and the dangerous degree of the second type of scene to at least one occupant in the vehicle is greater than the dangerous degree of the first type of scene to the at least one occupant; the gas supply system is controlled to release the second gas to the at least one occupant. That is, in the embodiment of the present application, the first gas in the ambient air is collected when the vehicle is in the first type of scene, and the first gas is converted into the second gas for storage; when the vehicle is in the second type of scene, the stored first gas is converted into the second gas and released to the occupant. The identification of the scene in which the vehicle is located is realized, and the gas supply system is automatically triggered based on the corresponding scene, thereby solving the technical problem of low safety of vehicle control and realizing the technical effect of improving the safety of vehicle control.
[0096] The technical solutions of the embodiments of the present application will be described below in conjunction with preferred embodiments.
[0097] At present, with the increase of the number of automobiles, accidents of vehicles falling into rivers, lakes and other water areas occur from time to time. After the vehicle falls into the water, the door is difficult to open due to the water pressure, and the electric window may fail due to short circuit, so that the window period for the occupant to escape is extremely short. More fatally, during the sinking process of the vehicle, the space in the vehicle compartment will be quickly filled with water, and the air will be squeezed out, causing the occupant to suffocate and lose the ability to save himself in a very short time, and eventually to die of drowning.
[0098] In the related art, the safety devices for the vehicle falling into the water mainly focus on the window breaker and the emergency hammer. However, the above devices have obvious defects, for example, in a panic environment, the occupant may not be able to find and use the above devices in time; even if the window is successfully broken, water will flow in instantly, accelerating the sinking of the vehicle, and possibly rushing the occupant away from the escape outlet, which is also very dangerous.
[0099] The purpose of the present application is to overcome the deficiencies of the prior art, and to provide an automatic, high-integration and rapid response gas supply system and control method. An automatic emergency system can provide critical minutes of breathing guarantee for the occupant at the initial stage of the vehicle falling into the water, and win valuable golden time for the occupant to keep awake, self-rescue or wait for rescue.
[0100] To achieve the above purpose, the present application adopts the following technical solutions.
[0101] The application discloses a vehicle-mounted water-falling emergency oxygen supply system, which comprises four core modules, namely, an oxygen production and storage module, an emergency triggering module, an oxygen supply execution module and a central control unit.
[0102] Optionally, the oxygen production and storage module is used to produce high-concentration oxygen by using the excess electric energy (for example, when the engine is running) through a pressure swing adsorption method, and then the high-concentration oxygen is converted into ozone by using an ozone generator. Ozone has active chemical properties, can be adsorbed on a specific adsorbent (for example, silica gel or activated carbon) or stored in a liquid state at low temperature, and can be stored in a high-density and low-risk manner. When needed, the ozone can be quickly decomposed into oxygen by heating or catalysis, and the efficiency is high and the oxygen production is large, so that the problems of long-term and safe storage of oxygen and the leakage and explosion risks of directly storing high-pressure oxygen are solved.
[0103] Optionally, the emergency triggering module adopts a multi-sensor fusion judgment strategy to avoid false triggering. The water pressure sensors arranged at the bottom and the side of the vehicle are combined with the vehicle body acceleration sensor, and CAN bus information (for example, an airbag collision signal and a door state) is optionally integrated, so that whether the vehicle is truly water-falling is comprehensively judged. Only when multiple conditions are met at the same time, the oxygen supply system is started.
[0104] Optionally, the oxygen supply execution module stores a folded oxygen mask in a separate cavity in the steering wheel. When the oxygen supply system is triggered, the mask cabin cover is blown open by a miniature blasting device (similar to an airbag igniter) at the same time or after the airbag is unfolded, and the mask is ejected to the range that can be reached by the driver's hand by using kinetic energy. At the same time, a quick electromagnetic valve is opened, and oxygen from the decomposition chamber is transported to the mask through a hose.
[0105] Optionally, the central control unit is used as the brain of the system, is responsible for processing sensor signals, making judgments, and accurately controlling the actions of each module according to a preset time sequence. The application also discloses an automatic process which is mainly used for preparation in peacetime and emergency in urgent time.
[0106] The technical effects of the application include that key 3-5 minute emergency oxygen is provided for the driver and passenger, the driver and passenger can keep awake and have physical strength before the vehicle cabin is completely water-falling, and the success rate of escaping or waiting for rescue by using a window breaking tool is greatly improved. The whole process is automatically triggered, and the driver and passenger do not need to perform any operation, so that the problem of people's panic in a critical moment is solved. The integration of the application and the steering wheel airbag does not occupy extra space in the vehicle, and meets the automobile design aesthetics and ergonomics. The technical path of "preparing ozone, storing ozone and decomposing oxygen" is adopted, the problem of long-term and safe storage of oxygen in a vehicle-mounted environment is solved, the energy density is high, and the safety is good. The triggering logic of the multi-sensor fusion in the application maximally avoids false triggering of the oxygen supply system caused by washing the vehicle and wading, and the reliability is high.
[0107] The method of the embodiment of the application is further illustrated below.
[0108] Figure 2 is a schematic diagram of a vehicle-mounted emergency oxygen supply system according to an embodiment of the application. As shown in the figure, the vehicle-mounted emergency oxygen supply system comprises an air filter, an air conditioner compressor, a cooler, an oxygen generator compressor, and an oxygen molecule separator. Figure 2
[0109] Optionally, the air filtered by the air filter or cooled by the cooler is delivered to the air conditioner compressor, and the air conditioner compressor can further output cold / hot air. For example, when the vehicle is in a first type of scenario, the engine of the vehicle drives the air conditioner compressor to work, at which time the air filtered by the air filter or cooled by the cooler is sent to the air conditioner compressor. The air conditioner compressor compresses the air, not only providing suitable cold / warm adjustment for the vehicle, but also using the high-pressure air generated by the air conditioner compressor as raw material for the subsequent oxygen generation process, thereby achieving efficient use of vehicle energy.
[0110] Optionally, the ozone cooled by the cooler is delivered to the oxygen generator compressor, and the oxygen generator compressor can further output compressed air to the oxygen molecule separator to generate oxygen. For example, the ozone converted by the ozone generator needs to be cooled by the cooler first to ensure its stability during transmission. The cooled ozone is delivered to the oxygen generator compressor, which pressurizes the ozone again and sends it to the oxygen molecule separator. The oxygen molecule separator uses PSA technology or membrane separation technology to efficiently separate oxygen from compressed air, which provides important technical support for the preparation of emergency oxygen.
[0111] Optionally, the cold / hot air and the oxygen are mixed to form high-oxygen mixed gas. For example, the separated oxygen and the cold / hot air provided by the air conditioner compressor can be combined in a specific mixing device, and by adjusting the ratio of oxygen to air, a mixed gas rich in oxygen can be finally formed. The high-oxygen mixed gas can directly release oxygen by rapid switching and control in emergency situations such as vehicle sinking, thereby providing life support for the passengers in the vehicle.
[0112] Optionally, the vehicle-mounted emergency oxygen supply system is uniformly coordinated and managed by a central control unit. The oxygen generation and storage module starts standby work after the vehicle is started, and automatically starts the oxygen generation and storage process when it is detected that the engine is running stably and the battery has sufficient power.
[0113] Optionally, by the above method, when the vehicle is in a first type of scenario such as normal driving or light wading, the vehicle-mounted water-falling emergency oxygen supply system can make full use of the excess power of the vehicle, such as engine power and high-pressure air generated by the air conditioner compressor, to efficiently prepare and store oxygen without affecting the normal operation of the vehicle and the comfort experience of the passengers.
[0114] Meanwhile, in a second type of scenario (i.e., vehicle water-falling or other emergency situations), the vehicle-mounted water-falling emergency oxygen supply system can quickly respond and switch to an emergency mode to provide stored oxygen or oxygen prepared on the spot to the driver and passengers through a specific oxygen supply execution module (such as an oxygen mask) to gain valuable time for escape or waiting for rescue. Through intelligent management of the central control unit, the vehicle-mounted water-falling emergency oxygen supply system of the present application can smoothly transition between the two scenarios, ensuring both energy utilization efficiency in daily use and timely and effective performance in critical situations, significantly improving the practicality and intelligence level of passive safety technology for automobiles.
[0115] In specific implementation, the vehicle-mounted water-falling emergency oxygen supply system makes scene judgment and system control decisions based on data from various sensors (such as water pressure sensors and acceleration sensors) and real-time information from the vehicle bus, ensuring that the system is in standby state for oxygen preparation and storage in the first type of scenario, and quickly starting the emergency oxygen supply process to provide life support for the driver and passengers in the second type of scenario. The above-mentioned automatic control system based on scene perception not only enhances the ability of the vehicle to respond to emergencies, but also comprehensively improves the safety performance of the automobile. Thus, the technical problem of low safety of vehicle control is solved, and the technical effect of improving the safety of vehicle control is achieved.
[0116] Figure 3 is a schematic diagram of the working principle of an oxygen preparation and storage module according to an embodiment of the present application. As shown in Figure 3 the working principle of the oxygen preparation and storage module includes an oxygen preparation system, a high-voltage electric generation device, and a vehicle cooling system. The high-voltage electric generation device provides high-voltage electricity for the oxygen preparation system, which converts oxygen into ozone in the discharge gap and releases heat.
[0117] The heat can be processed by the vehicle cooling system, and finally the oxygen preparation system can output a mixture containing oxygen and ozone and supply the mixture into the oxygen storage tank. The oxygen preparation system also includes electrodes and a dielectric body.
[0118] Optionally, the oxygen generation system can output a mixture of oxygen and ozone, and supply the mixture into the oxygen storage tank. Ozone is unstable at normal temperature and pressure, but through the specific adsorption or liquefaction technology, it can be safely and densely stored in the oxygen storage tank. When the vehicle detects a water-landing or other emergency situation requiring emergency oxygen supply, the ozone in the oxygen storage tank can be quickly converted into oxygen by a catalyst or heating means to provide life support for the occupants in the vehicle.
[0119] Figure 4 is a schematic diagram of a cross-sectional structure of a steering wheel integrated with an oxygen supply execution module according to an embodiment of the present application. As shown in FIG. 4, the cross-sectional structure of the steering wheel integrated with the oxygen supply execution module includes: the oxygen supply execution module ① located in the steering wheel ②, arranged side by side with the airbag ③. It also includes a mask cavity ④, a miniature blasting device ⑤, a folded oxygen mask ⑥, and an oxygen delivery hose ⑦. The oxygen delivery hose is connected to the oxygen supply pipeline leading to the oxygen storage tank / decomposition chamber through a quick connector.
[0120] Optionally, when the water pressure sensor of the emergency trigger module detects a continuously rising water pressure, and the acceleration sensor detects a weightlessness signal similar to falling, the central control unit makes a water-landing determination within milliseconds. Subsequently, the central control unit performs the following actions, including: sending an instruction to the oxygen generation and storage module to start the heating wire of the high-temperature decomposition chamber, and at the same time, releasing the ozone in the oxygen storage tank into the decomposition chamber. Ozone is rapidly decomposed into oxygen at 500-600 degrees Celsius; almost at the same time, an instruction is sent to the oxygen supply execution module to trigger the miniature blasting device ⑤, which blows open the cover plate of the mask cavity ④, and ejects the oxygen mask ⑥; opens the quick electromagnetic valve, and delivers the high-purity oxygen generated by decomposition to the driver through the hose. The entire process is completed within 1-2 seconds, ensuring that the driver can obtain the necessary oxygen for life before the vehicle is submerged.
[0121] Optionally, the exhaust system can automatically respond and quickly start the oxygen supply process within a very short time (such as 1-2 seconds) to provide immediate life support to the occupants. For example, when the exhaust system detects that the vehicle is in a water-landing scenario (based on the water pressure sensor and acceleration sensor, as well as other acquisition modules for combined judgment); the gas supply system sends an instruction to the oxygen generation and storage module to start the heating wire of the high-temperature decomposition chamber, prompting the ozone in the oxygen storage tank to be rapidly converted into oxygen. The above process can quickly and efficiently generate high-purity oxygen, providing a high-quality gas source for emergency oxygen supply. Through the cooperation of the oxygen delivery hose and the quick electromagnetic valve, the above oxygen can be quickly and safely delivered to the area where the driver is located.
[0122] Optionally, the oxygen supply execution module is integrated in the steering wheel to save space in the vehicle and ensure that the oxygen mask is within the reach of the driver. The oxygen mask is ejected by a miniature explosive device to provide instant protection for the occupants when the exhaust system is activated.
[0123] Optionally, by the above method, the exhaust system can eliminate the risk of the occupants searching for an oxygen mask in an emergency, avoid oxygen supply failure due to panic or operation delay, and greatly improve the survival opportunity in an emergency, thereby solving the technical problem of low safety of vehicle control and achieving the technical effect of improving the safety of vehicle control.

The execution module can be used to represent a collection of hardware components that specifically implement emergency air supply.
[0133] In the embodiment of the present application, when the triggering module receives a signal that the current environment of the vehicle is the second type scene, the air supply system is started by starting the execution module.
[0134] Optionally, the triggering module receives a signal from the sensor, and determines whether the conditions of the second type of scenario are met; when it is determined that the vehicle is in a water-landing scenario, the triggering module sends a start command to the execution module, instructing the first cavity and the second cavity to operate in sequence or simultaneously; at a first time, the first cavity of the execution module receives the start command, triggering the deployment mechanism of the airbag, and the airbag is immediately deployed to provide collision protection for the driver; at a second time, the second cavity of the execution module responds to the command, and pushes the gas release device (oxygen mask) out through a micro-explosion device or other mechanism to reach an area where the driver can quickly operate.
[0135] As an optional implementation, the vehicle includes a steering wheel, the steering wheel includes a first cavity and a second cavity, the first cavity is used to store an airbag assembly, and the second cavity is used to store a gas release device, and the gas supply system includes a decomposition chamber, and in response to the scenario being a second type of scenario, the gas supply system is controlled to convert a first gas into a second gas, including: in response to the scenario being a second type of scenario, at a first time, the first cavity is controlled to release the airbag assembly, and at a second time, the second cavity is controlled to release the gas release device, wherein the first time is the same as the second time, or the first time is earlier than the second time; in the process of releasing the gas release device, the first gas is decomposed into the second gas in the decomposition chamber by using a heating operation or a catalytic operation; the gas release device is propelled into an operable area of the occupant by using the power of the gas release device; and in response to the occupant completing wearing of the gas release device from the operable area, the second gas is transmitted to the gas release device through the decomposition chamber to release the second gas to the occupant.

The airbag assembly can be used to represent the airbag. The second cavity can be used to represent another storage region in the interior of the steering wheel and separate from the airbag cavity, and used to store a gas release device, such as a folded oxygen mask and related mechanical components.
