Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to an environmental control system and method for vehicle cabins. Background Technology

[0002] With the increasing demand for self-driving tours and long-distance travel, driving in low-oxygen environments such as plateaus and mountains is becoming more and more common. When vehicles travel at high altitudes, the external atmospheric pressure decreases significantly with increasing altitude, directly leading to a drop in the partial pressure of oxygen inhaled by occupants. This can easily trigger altitude sickness symptoms such as headaches, fatigue, difficulty concentrating, and even impaired cardiopulmonary function. To alleviate these problems, solutions for regulating the in-vehicle environment are needed. Summary of the Invention

[0003] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an environmental regulation system and method for vehicle cabins, which solves the technical problem of the need for in-vehicle environmental regulation when vehicles are traveling in high-altitude areas.

[0004] To achieve the above objectives, the main technical solutions adopted by the present invention include: The first aspect of the present invention provides an environmental control system for a vehicle cabin.

[0005] The environmental regulation system for a vehicle cabin proposed in this embodiment of the invention includes: The environmental sensing module is used to collect the external air pressure value, the external oxygen concentration value, the internal air pressure value, the internal oxygen concentration value, and the blood oxygen saturation sensor value of the driver and passengers. The scene semantic encoding module is used to acquire vehicle geographic coordinate data and image frames of the vehicle's surrounding environment. After the built-in encoder performs semantic segmentation and geographic label mapping on the vehicle geographic coordinate data and image frames of the vehicle's surrounding environment, it outputs scene semantic labels that reflect the current external geographical features of the vehicle. A central decision-making and reasoning module, connected to the environmental perception module and the scene semantic encoding module, is used to compare the blood oxygen saturation sensor value of the driver and passenger with a preset safety threshold. When the blood oxygen saturation sensor value of the driver and passenger is higher than the preset safety threshold, a first control instruction set is generated using the scene semantic tag as a retrieval index; when the blood oxygen saturation sensor value of the driver and passenger is lower than or equal to the preset safety threshold, a second control instruction set is generated. A physical environment closed-loop execution loop, connected to the central decision-making and reasoning module, is used to adjust the oxygen partial pressure inside the vehicle cabin based on the external air pressure value, the external oxygen concentration value, the internal air pressure value, the internal oxygen concentration value, and the second control command set; and The sensory environment collaborative execution link is connected to the central decision-making reasoning module and is used to control the microfluidic spray matrix installed on the dashboard or center armrest box to release odor molecules based on the first control instruction set and the scene semantic tags as input indexes.

[0006] In some instances, the sensory environment collaborative execution link is used to control the semiconductor cooling chip integrated in the vehicle's sunroof area to generate a zoned temperature field and to control the micro-blade array integrated in the vehicle's sunroof area to generate a differentiated airflow field, based on the first control instruction set and using the scene semantic tags as input indices.

[0007] In some instances, the scene semantic coding module includes: The geographic coordinate parsing unit receives the vehicle geographic coordinate data as input and performs map matching between the vehicle geographic coordinate data and the geographic information database pre-stored in the vehicle's on-board storage. It outputs a primary geographic semantic label reflecting the current administrative division, altitude range, and terrain type. The image semantic segmentation unit receives the image frame of the vehicle's surrounding environment as input and performs pixel-level semantic segmentation of the image frame of the vehicle's surrounding environment through a convolutional neural network, and outputs an environmental object mask map containing multiple object categories. The multimodal label fusion encoder has its input ends connected to the output ends of the geographic coordinate parsing unit and the image semantic segmentation unit, respectively. It is used to perform cross-attention fusion of the geographic semantic primary labels and the environmental object mask map, and after normalization processing, outputs the scene semantic labels from the output end. The scene semantic labels include climate type labels, landform type labels and vegetation cover labels.

[0008] In some instances, the physical environment closed-loop execution loop is specifically used for The partial pressure of oxygen inside the vehicle is determined based on the air pressure value and the oxygen concentration value inside the vehicle. The partial pressure of oxygen inside the vehicle is used as a feedback input and the difference between the partial pressure of oxygen inside the vehicle and the upper and lower limits of the preset equivalent plain parameter range is determined by an internal deviation comparator. The difference is converted into a gas separation flow rate regulation amount and a mixed gas pressurization ratio regulation amount based on a proportional-integral-derivative controller. Based on the gas separation flow rate adjustment, the oxygen-enriched gas output flow rate of the membrane separation component in the gas separation unit is adjusted to change the in-vehicle oxygen concentration in the mixed gas. Based on the aforementioned mixed-gas boosting ratio adjustment amount, the rate at which the variable frequency compressor in the boosting unit pressurizes the mixed gas into the cabin is adjusted to regulate the total pressure inside the vehicle. Based on the changes in the in-vehicle oxygen concentration and the total in-vehicle pressure, the in-vehicle oxygen partial pressure is adjusted within the vehicle cabin.

[0009] In some instances, the sensory environment collaborative execution chain includes: The odor retrieval and proportioning sub-link receives the scene semantic tag at the input end, and uses the scene semantic tag as the retrieval key to perform feature vector recall processing in the odor vector database pre-stored in the vehicle memory. The recalled vector is then decoded by the decoder to perform molecular formula inverse decoding, and outputs a first execution signal containing the fragrance liquid type identifier and various liquid volume proportion parameters. Based on the first execution signal, the microfluidic spray matrix is ​​driven to spray fragrance droplets according to the fragrance liquid type identifier and the volume ratio parameters of various liquids, thereby releasing the corresponding scent molecule combination.

[0010] In some instances, the sensory environment collaborative execution chain includes: The airflow temperature control sub-link receives the scene semantic tag at its input end and, based on the climate type information in the scene semantic tag, outputs a cooling airflow signal from the first output end to control the cooling power of the semiconductor refrigeration chip and the deflection angle of the honeycomb micro-blades at the vehicle roof air vents, and outputs a natural airflow signal from the second output end to control the opening of the valves of the air vents under the vehicle dashboard and under the front seats; wherein, the cooling airflow signal is used to drive the micro-blade array integrated in the sunroof area of ​​the vehicle roof to generate a differentiated airflow field, and to drive the semiconductor refrigeration chip to reduce the temperature of the air flowing through the roof air vents, forming a vertically partitioned temperature field.

[0011] In some instances, the gas separation unit is installed in a pre-reserved mounting location on the vehicle chassis or in the trunk; the gas separation unit includes an oil-free scroll compressor and a membrane separation assembly connected in sequence; wherein, The air inlet of the oil-free scroll compressor is connected to outside air through the vehicle's air intake pipe; the oil-free scroll compressor is used to pressurize the outside air and then input it into the membrane separation assembly. The membrane separation assembly is used to selectively permeate and separate oxygen and nitrogen molecules in pressurized air, and output the oxygen-enriched stream from the oxygen outlet to the oxygen buffer tank.

[0012] In some instances, the microfluidic spray matrix is ​​installed in the center of the vehicle's dashboard or inside the center armrest. The input terminal of the microfluidic spray matrix receives the first execution signal, and the pulse width modulation controller converts the various liquid volume ratio parameters into the duty cycle and spray frequency commands of each micropump, driving the micropumps corresponding to multiple fragrance liquid storage chambers to spray fragrance droplets in sequence.

[0013] A second aspect of the present invention provides a method for environmental regulation in a vehicle cabin, comprising: The environmental sensing module collects the external air pressure value, external air oxygen concentration value, internal air pressure value, internal air oxygen concentration value, and blood oxygen saturation sensor value of the driver and passengers. The scene semantic coding module acquires vehicle geographic coordinate data and image frames of the vehicle's surrounding environment. After semantic segmentation and geographic label mapping are performed on the vehicle geographic coordinate data and image frames of the vehicle's surrounding environment by the built-in encoder, scene semantic labels reflecting the current external geographical features of the vehicle are output. The central decision-making and reasoning module compares the blood oxygen saturation sensor value of the driver and passenger with a preset safety threshold. When the blood oxygen saturation sensor value of the driver and passenger is higher than the preset safety threshold, a first control instruction set is generated using the scene semantic tag as the retrieval index. When the blood oxygen saturation sensor value of the driver and passenger is lower than or equal to the preset safety threshold, a second control instruction set is generated. The closed-loop execution circuit of the physical environment adjusts the oxygen partial pressure inside the vehicle cabin based on the external air pressure, external oxygen concentration, internal air pressure, internal oxygen concentration, and the second control command set; and Based on the first control instruction set and using the scene semantic tags as input indexes, the sensory environment collaborative execution link controls the microfluidic spray matrix installed on the dashboard or center console to release odor molecules.

[0014] A third aspect of the present invention provides a vehicle, characterized in that it includes the environmental regulation system for the vehicle cabin described in the first aspect.

[0015] This invention provides an environmental regulation system for a vehicle cabin, comprising: an environmental perception module for collecting external air pressure, external oxygen concentration, internal air pressure, internal oxygen concentration, and blood oxygen saturation sensor values ​​of the driver and passengers; a scene semantic encoding module for acquiring vehicle geographic coordinate data and image frames of the vehicle's surrounding environment, and performing semantic segmentation and geographic label mapping on the vehicle geographic coordinate data and image frames of the vehicle's surrounding environment through a built-in encoder, and outputting scene semantic labels reflecting the current external geographical features of the vehicle; and a central decision-making and reasoning module connected to the environmental perception module and the scene semantic encoding module, for comparing the blood oxygen saturation sensor values ​​of the driver and passengers with preset safety thresholds, and when the driver...

Detailed Implementation

[0017] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The environmental regulation system for vehicle cabins proposed in this invention addresses the need for in-vehicle environmental regulation when vehicles travel at high altitudes. By coordinating the environmental perception module, scene semantic encoding module, central decision-making and reasoning module, physical environment closed-loop execution loop, and sensory environment collaborative execution link, it facilitates the dynamic coordination of physical environment and sensory experience in vehicle cabin environmental regulation with occupant blood oxygen safety as the highest priority. This helps to ensure occupant safety while improving the driving experience.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] Figure 1 This is a schematic diagram of an environmental regulation system for a vehicle cabin, provided as an embodiment of the present invention. Figure 1 As shown, the environmental regulation system for a vehicle cabin proposed in this embodiment of the invention includes: The environmental perception module 01 is used to collect the external air pressure value, the external oxygen concentration value, the internal air pressure value, the internal oxygen concentration value, and the blood oxygen saturation sensor value of the driver and passengers. Scene semantic encoding module 02 is used to acquire vehicle geographic coordinate data and image frames of the vehicle's surrounding environment. After the built-in encoder performs semantic segmentation and geographic label mapping on the vehicle geographic coordinate data and image frames of the vehicle's surrounding environment, it outputs scene semantic labels that reflect the current external geographic landscape of the vehicle. The central decision-making reasoning module 03, connected to the environmental perception module and the scene semantic encoding module, is used to compare the blood oxygen saturation sensor value of the driver and passenger with a preset safety threshold. When the blood oxygen saturation sensor value of the driver and passenger is higher than the preset safety threshold, a first control instruction set is generated using the scene semantic tag as a retrieval index; when the blood oxygen saturation sensor value of the driver and passenger is lower than or equal to the preset safety threshold, a second control instruction set is generated. Physical environment closed-loop execution loop 04, connected to the central decision-making and reasoning module, is used to adjust the oxygen partial pressure inside the vehicle cabin based on the external air pressure value, the external oxygen concentration value, the internal air pressure value, the internal oxygen concentration value, and the second control command set; and The sensory environment collaborative execution link 05 is connected to the central decision-making reasoning module and is used to control the microfluidic spray matrix installed on the dashboard or center armrest box to release odor molecules based on the first control instruction set and the scene semantic label as the input index.

[0021] In this exemplary embodiment, the environmental perception module includes an external air pressure sensor and an oxygen concentration sensor located on the front bumper or exterior rearview mirror of the vehicle, an internal air pressure sensor and an oxygen concentration sensor located at the height of the occupant's breathing zone on the B-pillar or the roof lining of the vehicle, and a reflective blood oxygen sensor integrated into the steering wheel rim or seat back, which respectively collect external ambient air pressure values, external ambient oxygen concentration values, internal ambient air pressure values, internal ambient oxygen concentration values, and blood oxygen saturation sensing values ​​of the driver and passengers.

[0022] In this exemplary embodiment, the scene semantic encoding module obtains vehicle geographic coordinate data through the vehicle-mounted GPS module, obtains image frames of the vehicle's surrounding environment through the vehicle-mounted front-view camera, and outputs scene semantic labels (such as "high-altitude snow mountain" or "low-altitude forest") after the above data is semantically segmented and geographically labeled by the built-in encoder.

[0023] The central decision-making reasoning module compares the blood oxygen saturation sensor value of the driver and passengers with a preset safety threshold (e.g., 92%). When the blood oxygen saturation is higher than 92%, a first set of control instructions is generated using the scene semantic tags as a retrieval index and sent to the sensory environment collaborative execution link; when the blood oxygen saturation is lower than or equal to 92%, a second set of control instructions is generated and sent to the physical environment closed-loop execution loop.

[0024] After receiving the second control command set, the physical environment closed-loop execution loop adjusts the oxygen partial pressure inside the vehicle based on the air pressure and oxygen concentration values ​​inside and outside the vehicle. After receiving the first control command set, the sensory environment collaborative execution link controls the microfluidic spray matrix to release corresponding odor molecules, using scene semantic tags as input indices.

[0025] In some instances, the sensory environment collaborative execution link is used to control the semiconductor cooling chip integrated in the vehicle's sunroof area to generate a zoned temperature field and to control the micro-blade array integrated in the vehicle's sunroof area to generate a differentiated airflow field, based on the first control instruction set and using the scene semantic tags as input indices.

[0026] In this exemplary embodiment, The sensory environment collaborative execution link is used to control the semiconductor cooling chip integrated in the vehicle roof sunroof area to generate a partitioned temperature field based on the first control instruction set and the scene semantic label as the input index, and to control the micro-blade array integrated in the vehicle roof sunroof area to generate a differentiated airflow field.

[0027] Specifically, when the scene semantic tag is a snow mountain, the semiconductor cooling chip operates at higher power, and its cold end cools the air flowing through the ceiling air outlet to a lower temperature (e.g., 8°C~12°C). The cold air naturally sinks to the head area of ​​the occupants, forming a cold zone. At the same time, the air outlets under the vehicle dashboard and under the front seats deliver uncooled airflow at natural temperature (approximately 25°C), forming a relatively warm zone in the foot area of ​​the occupants, thus creating a vertically partitioned temperature field with a cooler upper section and a warmer lower section. Each micro-blade in the micro-blade array is driven by an independent micro-motor, deflecting at different angles (e.g., ±15°~±30°), cutting the cooled airflow into fine jets with different directions, simulating the turbulent wind feeling in a natural valley, and forming a differentiated airflow field.

[0028] The above solution allows passengers to feel a cool sensation on their heads that matches the snow mountain scene, while keeping their feet relatively warm. At the same time, the airflow direction changes constantly rather than blowing directly on them, which helps to enhance the immersion in the scene and avoids the headache caused by direct airflow from traditional air conditioners.

[0029] In some instances, the scene semantic coding module includes: The geographic coordinate parsing unit receives the vehicle geographic coordinate data as input and performs map matching between the vehicle geographic coordinate data and the geographic information database pre-stored in the vehicle's on-board storage. It outputs a primary geographic semantic label reflecting the current administrative division, altitude range, and terrain type. The image semantic segmentation unit receives the image frame of the vehicle's surrounding environment as input and performs pixel-level semantic segmentation of the image frame of the vehicle's surrounding environment through a convolutional neural network, and outputs an environmental object mask map containing multiple object categories. The multimodal label fusion encoder has its input ends connected to the output ends of the geographic coordinate parsing unit and the image semantic segmentation unit, respectively. It is used to perform cross-attention fusion of the geographic semantic primary labels and the environmental object mask map, and after normalization processing, outputs the scene semantic labels from the output end. The scene semantic labels include climate type labels, landform type labels and vegetation cover labels.

[0030] In this exemplary embodiment, the scene semantic coding module includes a geographic coordinate parsing unit, an image semantic segmentation unit, and a multimodal label fusion encoder.

[0031] The geographic coordinate parsing unit receives vehicle geographic coordinate data (latitude, longitude, and altitude) as input. It then performs map matching between this data and a geographic information database pre-stored in the vehicle's onboard storage, outputting a primary geographic semantic label reflecting the current administrative division, altitude range, and terrain type. For example, when the vehicle is located at 30°N, 102°E, and 3500m above sea level, the matching result would be Sichuan Province / Ganzi Prefecture / High Altitude / Mountainous Area.

[0032] The input of the image semantic segmentation unit is an image frame of the vehicle's surrounding environment. The image frame is then semantically segmented at the pixel level using a convolutional neural network, and an environmental object mask map containing multiple object categories such as sky, vegetation, mountains, water, and buildings is output.

[0033] The input of the multimodal label fusion encoder is connected to the output of the geographic coordinate parsing unit and the output of the image semantic segmentation unit, respectively. The encoder performs cross-attention fusion of the geographic semantic primary label and the environmental object mask map, and outputs the scene semantic label after normalization. The scene semantic label includes climate type label (e.g., cold temperate zone), landform type label (e.g., alpine meadow), and vegetation cover label (e.g., coniferous forest).

[0034] The above solution, by integrating geographic coordinate data and visual image data, facilitates a multi-dimensional semantic understanding of the vehicle's external environment, resulting in richer and more accurate scene semantic labels, and providing a high-quality input index for subsequent odor retrieval and temperature control parameter decoding.

[0035] In some instances, the physical environment closed-loop execution loop is specifically used for The partial pressure of oxygen inside the vehicle is determined based on the air pressure value and the oxygen concentration value inside the vehicle. The partial pressure of oxygen inside the vehicle is used as a feedback input and the difference between the partial pressure of oxygen inside the vehicle and the upper and lower limits of the preset equivalent plain parameter range is determined by an internal deviation comparator. The difference is converted into a gas separation flow rate regulation amount and a mixed gas pressurization ratio regulation amount based on a proportional-integral-derivative controller. Based on the gas separation flow rate adjustment, the oxygen-enriched gas output flow rate of the membrane separation component in the gas separation unit is adjusted to change the in-vehicle oxygen concentration in the mixed gas. Based on the aforementioned mixed-gas boosting ratio adjustment amount, the rate at which the variable frequency compressor in the boosting unit pressurizes the mixed gas into the cabin is adjusted to regulate the total pressure inside the vehicle. Based on the changes in the in-vehicle oxygen concentration and the total in-vehicle pressure, the in-vehicle oxygen partial pressure is adjusted within the vehicle cabin.

[0036] In this exemplary embodiment, the partial pressure of oxygen inside the vehicle cabin is adjusted based on the changes in the in-vehicle oxygen concentration and the total in-vehicle pressure, so that the total in-vehicle pressure and the partial pressure of oxygen inside the vehicle converge within the range of the equivalent plain environmental parameters.

[0037] The partial pressure of oxygen inside the vehicle is determined based on the air pressure value and the oxygen concentration value inside the vehicle (partial pressure of oxygen = air pressure value × oxygen concentration value). The partial pressure of oxygen inside the vehicle is used as a feedback input quantity, and the difference between the partial pressure of oxygen inside the vehicle and the upper and lower limits of the preset equivalent plain parameter range (e.g., 20.5 kPa to 21.5 kPa) is determined by an internal deviation comparator.

[0038] Secondly, the difference is converted into two independent control quantities based on the proportional-integral-derivative (PID) controller: (1) gas separation flow rate regulation quantity; (2) mixed gas boosting ratio regulation quantity.

[0039] Then, based on the gas separation flow rate adjustment, the oxygen-enriched gas output flow rate of the membrane separation component in the gas separation unit is adjusted to change the in-vehicle oxygen concentration in the mixed gas. For example, when the oxygen partial pressure is low, the inlet pressure or effective membrane area of ​​the membrane separation component is increased to increase the output flow rate of the oxygen-enriched gas, thereby increasing the oxygen content in the mixing unit from 20.5% to 22.5%.

[0040] Simultaneously, based on the aforementioned air-fuel mixture boosting ratio adjustment, the rate at which the variable frequency compressor in the boosting unit injects the air-fuel mixture into the cabin is adjusted to regulate the total pressure inside the vehicle. For example, when the total pressure inside the vehicle drops from 98 kPa to 94 kPa, the speed of the variable frequency compressor is increased, raising the air injection rate from 10 L / min to 18 L / min, thus pushing the total pressure inside the vehicle back to 98 kPa.

[0041] Ultimately, based on the coordinated change in the in-vehicle oxygen concentration and the total in-vehicle pressure, the in-vehicle oxygen partial pressure converges within the equivalent plain parameter range.

[0042] The above-described scheme, through PID dual-variable coordinated regulation, facilitates closed-loop precise control with oxygen partial pressure as the ultimate goal. Compared to schemes that control air pressure or oxygen concentration alone, this scheme can compensate for fluctuations in total pressure by dynamically adjusting the oxygen concentration, and supplement it by adjusting the total pressure when the oxygen concentration is limited to a safe upper limit, thus ensuring reliable oxygen supply under various altitude conditions.

[0043] In some instances, the sensory environment collaborative execution chain includes: The odor retrieval and proportioning sub-link receives the scene semantic tag at the input end, and uses the scene semantic tag as the retrieval key to perform feature vector recall processing in the odor vector database pre-stored in the vehicle memory. The recalled vector is then decoded by the decoder to perform molecular formula inverse decoding, and outputs a first execution signal containing the fragrance liquid type identifier and various liquid volume proportion parameters. Based on the first execution signal, the microfluidic spray matrix is ​​driven to spray fragrance droplets according to the fragrance liquid type identifier and the volume ratio parameters of various liquids, thereby releasing the corresponding scent molecule combination.

[0044] In this exemplary embodiment, the sensory environment collaborative execution link includes an odor retrieval and proportioning sub-link.

[0045] The input end of the odor retrieval and proportioning sub-link receives the scene semantic tag (e.g., high-altitude snow mountain), and uses the scene semantic tag as the retrieval key to perform feature vector recall processing in the odor vector database pre-stored in the vehicle's onboard memory. The odor vector database pre-associates and maps geographical semantic tags (e.g., snow mountain, forest, grassland) with odor molecular formula feature vectors. After the recalled vector is decoded by the decoder to perform molecular formula inverse decoding, a first execution signal is output, which includes the fragrance liquid type identifier (e.g., [01, 03]) and various liquid volume proportion parameters (e.g., [0.7, 0.3]).

[0046] Based on the first execution signal, the microfluidic spray matrix is ​​driven to spray fragrance droplets according to the fragrance essence type identifier and the volume ratio parameters of each essence. For example, for a snow mountain scene, the type identifier [01,03] corresponds to a cool-feel essence and an earthy-feel essence, and the ratio parameter [0.7,0.3] indicates that the two are sprayed at a volume flow ratio of 7:3, and after mixing in the mixing chamber, a cool snow mountain scent with an earthy undertone is released.

[0047] The above solution facilitates the automated mapping from scene semantics to scent formula, enabling the scent release to dynamically adjust according to changes in the geographical landscape of the vehicle, avoiding the disharmony of a fixed scent not matching the scene, and significantly enhancing the immersive experience of the occupants.

[0048] In some instances, the sensory environment collaborative execution chain includes: The airflow temperature control sub-link receives the scene semantic tag at its input end and, based on the climate type information in the scene semantic tag, outputs a cooling airflow signal from the first output end to control the cooling power of the semiconductor refrigeration chip and the deflection angle of the honeycomb micro-blades at the vehicle roof air vents, and outputs a natural airflow signal from the second output end to control the opening of the valves of the air vents under the vehicle dashboard and under the front seats; wherein, the cooling airflow signal is used to drive the micro-blade array integrated in the sunroof area of ​​the vehicle roof to generate a differentiated airflow field, and to drive the semiconductor refrigeration chip to reduce the temperature of the air flowing through the roof air vents, forming a vertically partitioned temperature field.

[0049] In this exemplary embodiment, the sensory environment collaborative execution link includes an airflow temperature control sub-link.

[0050] The input end of the airflow temperature control sub-link receives the scene semantic tag and calculates the zoned temperature setting value based on the climate type information in the scene semantic tag. For example, when the climate type tag is cold temperate zone, the ceiling air outlet temperature is set to 10℃ and the foot air outlet temperature is set to 22℃; when the climate type tag is tropical zone, the ceiling air outlet temperature is set to 18℃ and the foot air outlet temperature is set to 24℃.

[0051] After processing, a cooling air volume signal is output from the first output terminal to control the cooling power of the semiconductor cooling chip and the deflection angle of the honeycomb micro blades at the air outlet of the vehicle roof, and a natural air volume signal is output from the second output terminal to control the opening of the air outlet valves under the vehicle dashboard and under the front seats.

[0052] The cooling airflow signal is used to drive the micro-blade array integrated in the sunroof area of ​​the vehicle roof to generate a differentiated airflow field, and to drive the semiconductor cooling chip to reduce the temperature of the air flowing through the roof air outlet, forming a vertically zoned temperature field. The natural airflow signal is used to control the valve opening of the lower air outlet and adjust the airflow in the foot area.

[0053] The above solution is based on scene semantic differential temperature control—the head area receives cool air of the corresponding temperature according to the scene climate type, and the foot area receives natural temperature air. This helps to form a vertical temperature difference that conforms to the laws of natural perception and avoids the problem of monotonous physical sensation caused by a single temperature field.

[0054] In some instances, the gas separation unit is installed in a pre-reserved mounting location on the vehicle chassis or in the trunk; the gas separation unit includes an oil-free scroll compressor and a membrane separation assembly connected in sequence; wherein, The air inlet of the oil-free scroll compressor is connected to outside air through the vehicle's air intake pipe; the oil-free scroll compressor is used to pressurize the outside air and then input it into the membrane separation assembly. The membrane separation assembly is used to selectively permeate and separate oxygen and nitrogen molecules in pressurized air, and output the oxygen-enriched stream from the oxygen outlet to the oxygen buffer tank.

[0055] In this exemplary embodiment, the gas separation unit is installed in a reserved mounting position on the vehicle chassis or in the trunk.

[0056] The gas separation unit includes an oil-free scroll compressor and a membrane separation assembly connected in sequence. The air inlet of the oil-free scroll compressor is connected to outside air through the vehicle's air intake pipe. The oil-free scroll compressor is used to pressurize the outside air (for example, pressurize it to 0.6~0.8MPa) and then input it into the membrane separation assembly.

[0057] The membrane separation unit uses a high-polymer hollow fiber membrane, which selectively separates oxygen and nitrogen molecules in pressurized air by utilizing the difference in permeation rates between oxygen and nitrogen molecules (the oxygen permeation rate is approximately 2 to 3 times that of nitrogen). The separated oxygen-enriched stream (oxygen concentration can reach 90% to 95%) is output from the oxygen outlet to an oxygen buffer tank for storage and subsequent gas mixing.

[0058] The above solution uses an oil-free scroll compressor, which helps to avoid air pollution from lubricating oil. It also uses a high-polymer hollow fiber membrane separation component to achieve continuous oxygen production without the need for chemical consumables, making it suitable for the continuous oxygen supply needs of vehicles traveling long distances.

[0059] In some instances, the microfluidic spray matrix is ​​installed in the center of the vehicle's dashboard or inside the center armrest. The input terminal of the microfluidic spray matrix receives the first execution signal, and the pulse width modulation controller converts the various liquid volume ratio parameters into the duty cycle and spray frequency commands of each micropump, driving the micropumps corresponding to multiple fragrance liquid storage chambers to spray fragrance droplets in sequence.

[0060] In this exemplary embodiment, the microfluidic spray matrix is ​​installed in the middle of the vehicle's dashboard or inside the center armrest box.

[0061] The input terminal of the microfluidic spray matrix receives the first execution signal (including the fragrance essence type identifier and ratio parameters), and the pulse width modulation (PWM) controller converts the volume ratio parameters of each essence into the duty cycle and spray frequency commands for each micropump. For example, the ratio parameters [0.7, 0.3] are converted into: micropump 1 PWM duty cycle 70% (700ms on, 300ms off per second), and micropump 3 PWM duty cycle 30% (300ms on, 700ms off per second).

[0062] The aforementioned PWM instructions drive micropumps corresponding to multiple fragrance essence storage tanks to sequentially spray fragrance droplets. Each micropump operates in a high-frequency pulse mode under PWM control, spraying a tiny amount of fragrance droplets (nanolithic to microolithic) each time, achieving precise measurement of the total spray volume.

[0063] The above solution uses PWM to precisely control the on-time and spray frequency of the micro-pump, which is conducive to the precise mixing and micro-spraying of various fragrance concentrates, avoiding the pungent smell caused by excessive release in traditional fragrance systems, while improving the utilization rate of fragrance.

[0064] The input end of the mixing unit is connected to the outlet of the oxygen buffer tank and the outside air supply port, respectively. After mixing pure oxygen and outside air according to the ratio calculated by the PID controller, the mixture is then pressurized into the vehicle cabin through the pressurization unit.

[0065] In this exemplary embodiment, the outlet of the nitrogen buffer tank is connected to the cleaning air inlet of the vehicle cabin air duct system and the pneumatic interface of the vehicle door / window inflation and sealing actuator via a branch pipe laid inside the vehicle door sill or chassis piping. The nitrogen output from the nitrogen buffer tank is used as cleaning air and input into the air duct system to purge and replace residual odor molecules before being discharged through the vehicle exhaust port. The nitrogen is also used as driving air and input into the inflation and sealing actuator to push its piston to generate mechanical displacement and perform the sealing and locking action of the vehicle door / window.

[0066] In this exemplary embodiment, the microfluidic spray matrix in the odor retrieval and proportioning sub-link is installed in the middle of the vehicle dashboard or inside the center armrest box. Its input terminal receives the fragrance liquid type identifier and proportioning parameters. The proportioning parameters are converted into the duty cycle and spray frequency commands of each micropump by the pulse width modulation (PWM) controller, driving the micropumps corresponding to multiple fragrance liquid storage chambers to spray fragrance droplets in sequence. At the same time, the high-frequency oscillator of the ultrasonic cold fog module installed in the same housing atomizes deionized water into cold fog particles. After the sprayed fragrance droplets and the cold fog particles are mixed in the mixing chamber, they are released into the cabin through the fog outlet set in the vehicle center console or B-pillar area.

[0067] In this exemplary embodiment, the semiconductor cooling chip integrated at the air outlet of the vehicle roof receives the power control value in the cooling airflow signal at its input end, generates cooling at its cold end and transfers it to the air flowing through the air outlet of the roof, outputting a cooled, downward airflow from the top; each micro-blade in the honeycomb micro-blade array set at the air outlet of the roof is driven by an independent micro-motor, receives the deflection angle signal respectively, and generates deflection in different directions, outputting a non-uniformly distributed differentiated airflow field from its air outlet surface; the hot end of the semiconductor cooling chip is connected to the insulation layer of the fragrance essence storage compartment installed in the dashboard or center armrest box through a heat conduction element laid in the inner lining of the vehicle roof, and outputs the recovered heat as an auxiliary heat source to the insulation layer to maintain the fluidity of the fragrance essence.

[0068] In this exemplary embodiment, the central decision-making inference engine also integrates a timing scheduler. The input of the timing scheduler is respectively connected to the physical response delay time parameters of the odor synthesis execution unit, the airflow temperature control execution unit, and the in-vehicle infotainment audio unit. After the internal calibration calculation module performs offset compensation processing on the preset trigger timestamps of each sensory event, it outputs the time synchronization execution axis of each actuator uniformly aligned from its output end as the time reference of the synchronization control signal, so that the odor release, airflow change and scene sound effect reach the perception surface of the driver and passengers at the same time.

[0069] In this exemplary embodiment, the preset equivalent plain environment parameter range uses oxygen partial pressure as the final target. The lower limit of the target range for oxygen partial pressure is set to 20.5 kPa, and the upper limit is set to 21.5 kPa, corresponding to a total pressure range of 95 kPa to 103 kPa. The feedback input of the PID controller is the current measured value of oxygen partial pressure inside the vehicle. After the difference calculated by the deviation comparator is input into the PID controller, its output simultaneously adjusts the opening of the oxygen proportional valve of the mixing unit and the speed of the variable frequency compressor of the booster unit.

[0070] In this exemplary embodiment, in the environmental perception input link, the external air pressure sensor and oxygen concentration sensor located on the front bumper or exterior rearview mirror of the vehicle are used to collect the original atmospheric parameters along the vehicle's driving path; the internal air pressure sensor and oxygen concentration sensor located at the height of the occupant's breathing zone on the B-pillar or roof lining of the vehicle are used to collect the actual internal parameters in the area at the height of the driver's and passenger's mouth and nose; the reflective blood oxygen sensor integrated into the steering wheel rim or seat back emits a dual-wavelength light signal through the driver's or passenger's fingers or back tissue, and its photodetector receives the change in reflected light intensity, which is then output as the blood oxygen saturation sensing value by the internal signal processing circuit.

[0071] In this exemplary embodiment, when the second control instruction set output by the central decision-making inference engine is triggered, the timing scheduler pauses the allocation of new time axis resources to the sensory environment collaborative execution link and switches the control cycle of the physical environment closed-loop execution loop from the normal mode to the high-response mode. In this mode, the integral time constant of the PID regulator is shortened to half of that in the normal mode to accelerate the response speed of the oxygen partial pressure converging to the target range and prioritize the safety of oxygen supply to the brain of the driver and passengers.

[0072] This invention provides a method for environmental regulation in a vehicle cabin. Figure 2 This is a flowchart illustrating a method for environmental regulation in a vehicle cabin, as provided in an embodiment of the present invention. Figure 2 As shown, environmental control methods include: Step 100: Collect the external air pressure value, external oxygen concentration value, internal air pressure value, internal oxygen concentration value, and blood oxygen saturation sensor value of the driver and passengers through the environmental perception module. Step 110: Obtain vehicle geographic coordinate data and vehicle surrounding environment image frames through the scene semantic coding module, and perform semantic segmentation and geographic label mapping processing on the vehicle geographic coordinate data and vehicle surrounding environment image frames through the built-in encoder, and output scene semantic labels that reflect the current external geographic landscape of the vehicle. Step 120: The central decision-making reasoning module compares the blood oxygen saturation sensor value of the driver and passenger with a preset safety threshold. When the blood oxygen saturation sensor value of the driver and passenger is higher than the preset safety threshold, a first control instruction set is generated using the scene semantic tag as the retrieval index. When the blood oxygen saturation sensor value of the driver and passenger is lower than or equal to the preset safety threshold, a second control instruction set is generated. Step 130: Adjust the oxygen partial pressure inside the vehicle cabin based on the external ambient air pressure, external ambient oxygen concentration, internal ambient air pressure, internal ambient oxygen concentration, and the second control command set through a physical environment closed-loop execution circuit; and Step 140: Based on the first control instruction set and using the scene semantic tags as input index, control the microfluidic spray matrix installed on the dashboard or center console to release odor molecules through the sensory environment collaborative execution link.

[0073] In this exemplary embodiment, the environmental perception module includes an external air pressure sensor and an oxygen concentration sensor located on the front bumper or exterior rearview mirror of the vehicle, an internal air pressure sensor and an oxygen concentration sensor located at the height of the occupant's breathing zone on the B-pillar or the roof lining of the vehicle, and a reflective blood oxygen sensor integrated into the steering wheel rim or seat back, which respectively collect external ambient air pressure values, external ambient oxygen concentration values, internal ambient air pressure values, internal ambient oxygen concentration values, and blood oxygen saturation sensing values ​​of the driver and passengers.

[0074] In this exemplary embodiment, the scene semantic encoding module obtains vehicle geographic coordinate data through the vehicle-mounted GPS module, obtains image frames of the vehicle's surrounding environment through the vehicle-mounted front-view camera, and outputs scene semantic labels (such as "high-altitude snow mountain" or "low-altitude forest") after the above data is semantically segmented and geographically labeled by the built-in encoder.

[0075] The central decision-making reasoning module compares the blood oxygen saturation sensor value of the driver and passengers with a preset safety threshold (e.g., 92%). When the blood oxygen saturation is higher than 92%, a first set of control instructions is generated using the scene semantic tags as a retrieval index and sent to the sensory environment collaborative execution link; when the blood oxygen saturation is lower than or equal to 92%, a second set of control instructions is generated and sent to the physical environment closed-loop execution loop.

[0076] After receiving the second control command set, the physical environment closed-loop execution loop adjusts the oxygen partial pressure inside the vehicle based on the air pressure and oxygen concentration values ​​inside and outside the vehicle. After receiving the first control command set, the sensory environment collaborative execution link controls the microfluidic spray matrix to release corresponding odor molecules, using scene semantic tags as input indices.
