Description

Technical Field

[0001] This disclosure relates to the field of automatic control technology, and in particular to a vehicle cabin control method and electronic equipment. Background Technology

[0002] With the development of intelligent cockpit technology, vehicles are gradually becoming capable of improving the driving experience by automatically adjusting cockpit-related control strategies. How to achieve more reasonable and efficient cockpit control in different usage scenarios has become an important research direction in the field of vehicle intelligence.

[0003] Current vehicle cabin control methods typically rely on adaptive adjustments to the cabin environment. For example, by monitoring environmental parameters such as temperature, humidity, air quality, or lighting conditions inside the vehicle, automatic control of air conditioning, ventilation, or other cabin functions can be implemented to reduce manual operation and improve ease of use. However, these methods primarily depend on the perception of the cabin environment and struggle to reflect the actual physiological state or individual differences of the driver and passengers. This can easily lead to a mismatch between the control strategy and the actual needs of the drivers and passengers, resulting in poor driving and riding comfort. Summary of the Invention

[0004] In view of the above problems, this disclosure provides a vehicle cabin control method and electronic device that overcomes or at least partially solves the problem of poor driving comfort in current vehicle cabin control schemes. The technical solution is as follows: A vehicle cabin control method, the method comprising: When sweat is detected in a preset area in the vehicle cabin, the sweat electrolyte index of the preset area is determined based on the target electrolyte data of the sweat. The preset area is the area in the vehicle cabin that comes into contact with the user. The sweat electrolyte index is used to characterize the user's sweating rate. Based on the sweat electrolyte index, the vehicle's cabin control strategy is determined, which is used to adjust the environmental parameters inside the vehicle's cabin. A cockpit control strategy is used to control the vehicle.

[0005] In the above solution, sweat is identified in a preset area within the vehicle cabin, and the sweat electrolyte index is determined based on the target electrolyte data of the sweat. This avoids interference from non-physiological fluids in judging the sweating rate, thus ensuring the accuracy and reliability of the sweat electrolyte index. Building on this, the sweat electrolyte index is incorporated into the cabin control strategy determination process. This allows the adjustment of vehicle cabin environmental parameters to no longer rely solely on the external environment or fixed thresholds, but rather to match the user's actual sweating state. This enables the perception and response to the user's physiological state, minimizing inconsistencies between cabin environment adjustments and user sensations, improving the precision of cabin environment adjustments, and ultimately enhancing vehicle cabin comfort and the overall driving experience.

[0006] Optionally, methods for identifying sweat in a predetermined area within the vehicle cabin include: Collect electrolyte characteristic data of liquid in a preset area in the vehicle cabin; the electrolyte characteristic data includes sodium ion concentration, potassium ion concentration, liquid temperature, and liquid conductivity rise rate. When the electrolyte characteristic data meets the following conditions, sweat is identified in a preset area in the vehicle cabin, and the electrolyte characteristic data is determined as the target electrolyte data of the user's sweat in the vehicle. The conditions include: sodium ion concentration greater than or equal to a first threshold, potassium ion concentration greater than or equal to a second threshold, liquid temperature within a preset temperature range, and liquid conductivity increase rate less than a preset rate threshold.

[0007] In this way, by collecting multi-dimensional electrolyte characteristic data such as sodium ion concentration, potassium ion concentration, liquid temperature, and conductivity rise rate of liquids in preset areas of the vehicle cabin, and only identifying the liquid as user sweat when the above characteristics simultaneously meet preset conditions, the liquid type can be comprehensively constrained from multiple dimensions such as composition characteristics, thermal characteristics, and dynamic change characteristics. This effectively distinguishes sweat from non-physiological liquids such as water and beverages, significantly reducing the probability of misidentification. This ensures the authenticity and stability of the target electrolyte data source, providing a reliable data foundation for the accurate calculation of sweat electrolyte index and the formulation of cabin control strategies based on user physiological state, thereby improving the credibility and robustness of the overall control decision.

[0008] Optionally, the preset area is the area where the steering wheel is located, or the area where the vehicle seat is located; collect electrolyte characteristic data of the liquid in the preset area of ​​the vehicle cabin, including: Electrolyte characteristic data of the fluid in the vehicle seat are collected through a fluid monitoring module installed in the vehicle seat. And / or, Electrolyte characteristic data of the liquid on the vehicle's steering wheel are collected through a liquid monitoring module installed in the steering wheel.

[0009] By setting the preset areas as the steering wheel area and / or the vehicle seat area, and collecting liquid electrolyte characteristic data of the corresponding areas through liquid monitoring modules installed on the vehicle seat or steering wheel, the correlation and accuracy between liquid collection and user sweat are improved by leveraging the fact that these areas are in long-term, direct contact with the user's body, reducing false positives caused by unknown liquid sources. Simultaneously, by independently or in combination monitoring multiple high-frequency contact areas, multi-point perception and cross-validation of the user's sweating status can be achieved, enhancing the stability and comprehensiveness of sweat recognition results. This provides a more reliable input for subsequent cabin control based on sweat electrolyte data, improving the accuracy of cabin environment adjustment and user comfort.

[0010] Optionally, before collecting electrolyte characteristic data of the fluid in the vehicle seat through the fluid monitoring module installed in the vehicle seat, the method further includes: Real-time monitoring of vehicle seat pressure values; When the pressure value exceeds the pressure threshold, the electrolyte characteristic data of the fluid in the vehicle seat are collected through the fluid monitoring module installed in the vehicle seat.

[0011] In this way, before collecting electrolyte characteristic data of the vehicle seat fluid, the pressure value of the vehicle seat is detected in real time, and the fluid monitoring module is only triggered to collect data when the pressure value exceeds a preset pressure threshold. This ensures that the vehicle seat is in an actual user-occupied state, thus avoiding invalid collection of environmental or residual fluids when no one is riding or when there is only slight contact, reducing the probability of false sampling and misjudgment. At the same time, by combining the pressure triggering condition with the fluid collection process, this method improves the correlation and timeliness between electrolyte characteristic data and the user's physiological state, reduces unnecessary detection energy consumption, and provides a more reliable and high-quality data foundation for the accurate formulation of subsequent sweat recognition and cabin control strategies.

[0012] Optionally, the target electrolyte data includes sodium ion concentration and potassium ion concentration; based on the target electrolyte data of sweat, the sweat electrolyte index of the preset area is determined, including: The sodium ion concentration and potassium ion concentration are weighted and summed according to preset weight values ​​to obtain the sweat electrolyte index.

[0013] By incorporating sodium and potassium ion concentrations from the target electrolyte data into the calculation of the sweat electrolyte index, and weighting and summing them according to preset weight values, the impact of different electrolyte components on sweating rate and fluid loss can be comprehensively reflected, avoiding the one-sidedness of a single ion indicator. Simultaneously, by setting weights, the role of key electrolytes can be highlighted based on actual application needs or statistical patterns, making the sweat electrolyte index adjustable and adaptable. This allows for a more accurate and stable representation of the user's sweating level, providing a quantitative and comparable decision-making basis for subsequent cabin control strategies based on the sweat electrolyte index, thus improving the rationality and precision of control strategy formulation.

[0014] Optionally, the sodium ion concentration and potassium ion concentration are weighted and summed according to preset weight values ​​to obtain the sweat electrolyte index, including: The product of sodium ion concentration and first weight value is determined as the first addend, the product of potassium ion concentration and second weight value is determined as the second addend, and the product of target ratio and third weight value is determined as the third addend; wherein, the target ratio is the ratio of sodium ion concentration to potassium ion concentration. The sum of the first addend, the second addend, and the third addend is determined as the sweat electrolyte index.

[0015] In this way, by weighting sodium ion concentration, potassium ion concentration, and target ratio with their corresponding weight values, and then summing the weighted results to obtain the sweat electrolyte index, a comprehensive quantitative framework can be established to characterize multiple electrolyte-related features and their interrelationships. This reflects both the absolute change in the content of a single electrolyte and the influence of the proportional characteristics of different electrolytes on sweating. This method allows for flexible adjustment of the contribution of different features through weight configuration, reducing the sensitivity of the results to fluctuations in a single indicator. This makes the sweat electrolyte index more stable and discriminative, thus more accurately reflecting the user's actual sweating rate and providing a reliable basis for the subsequent refined and personalized adjustment of cabin control strategies.

[0016] Optionally, based on the sweat electrolyte index, the vehicle's cabin control strategy can be determined, including: When the sweat electrolyte index is less than or equal to the first index threshold, the current cabin control strategy is maintained; When the sweat electrolyte index is greater than the first index threshold and less than or equal to the second index threshold, the heating level will be reduced to the first preset level, or the fan ventilation level will be increased to the first preset level. When the sweat electrolyte index is greater than the second index threshold, turn off the heating function, or adjust the fan ventilation level to the highest level and lower the air conditioner temperature to the preset temperature threshold.

[0017] By dividing the sweat electrolyte index into multiple ranges and assigning different levels of cabin control strategies to each, the cabin environment can be adjusted in a graded and gradual manner based on changes in the user's sweating rate. When the sweating rate is low, the current control strategy is maintained to avoid discomfort and increased energy consumption caused by frequent adjustments. When the sweating rate is moderate, the heating level is appropriately reduced or the ventilation level is increased to achieve gentle intervention, balancing comfort and energy efficiency. When the sweating rate is high, stronger cooling and ventilation measures are taken to quickly improve the cabin thermal environment. This graded control method establishes a clear correspondence between cabin environment adjustment and the user's physiological state, improving the rationality and continuity of control response, reducing the occurrence of over- or under-adjustment, thereby improving cabin comfort and the overall driving experience.

[0018] Optionally, the vehicle cabin control method may also include: collecting user feedback within a preset time period after the vehicle is controlled using a cabin control strategy; When the user feedback is negative, the values ​​of the first exponential threshold and the second exponential threshold are increased by the first value. When the user feedback is positive, the values ​​of the first exponential threshold and the second exponential threshold are reduced by the second value.

[0019] By introducing a user feedback mechanism within a preset time period after the cabin control strategy is executed, and dynamically adjusting the first and second index thresholds based on the feedback results, the mapping relationship between the sweat electrolyte index and the cabin control strategy can be adaptively optimized. When the user provides negative feedback, raising the threshold reduces the sensitivity of the control strategy triggering, avoiding over-adjustment; when the user provides positive feedback, lowering the threshold improves the system's responsiveness to changes in sweating status, making the control strategy more aligned with the user's subjective comfort. This approach achieves closed-loop adjustment based on user experience, continuously refining control parameters, gradually bringing the cabin control strategy towards a personalized and optimal state, thereby improving comfort stability and user satisfaction during long-term use.

[0020] Optionally, the vehicle cockpit control method also includes: after controlling the vehicle using a cockpit control strategy, controlling the in-vehicle screen to display a prompt message; the prompt message is used to indicate that the cockpit control strategy has taken effect.

[0021] In this way, after the vehicle is controlled using the cockpit control strategy, a prompt message is displayed on the in-vehicle screen to indicate that the cockpit control strategy has taken effect. This provides intuitive feedback to the user, enhancing their awareness of the reasons for and status of changes in the cockpit environment and preventing confusion or misoperation due to changes in environmental parameters. Simultaneously, this prompt mechanism helps improve the transparency and explainability of human-machine interaction, allowing users to understand the system's working status in a timely manner, increasing their trust and sense of control over the automatic control functions, thereby improving the overall cockpit interaction experience and user satisfaction.

The determination module is used to determine the vehicle's cabin control strategy based on the sweat electrolyte index.

[0023] Optionally, the recognition module is also used for: Collect electrolyte characteristic data of liquid in a preset area in the vehicle cabin; the electrolyte characteristic data includes sodium ion concentration, potassium ion concentration, liquid temperature, and liquid conductivity rise rate. When the electrolyte characteristic data meets the following conditions, sweat is identified in a preset area in the vehicle cabin, and the electrolyte characteristic data is determined as the target electrolyte data of the user's sweat in the vehicle. The conditions include: sodium ion concentration greater than or equal to a first threshold, potassium ion concentration greater than or equal to a second threshold, liquid temperature within a preset temperature range, and liquid conductivity increase rate less than a preset rate threshold.

[0024] Optionally, the preset area is the area where the steering wheel is located, or the area where the vehicle seat is located; The recognition module is specifically used for: Electrolyte characteristic data of the fluid in the vehicle seat are collected through a fluid monitoring module installed in the vehicle seat. And / or, Electrolyte characteristic data of the liquid on the vehicle's steering wheel are collected through a liquid monitoring module installed in the steering wheel.

[0025] Optionally, the recognition module is also used for: Before collecting electrolyte characteristic data of the fluid in the vehicle seat through the fluid monitoring module installed in the vehicle seat, the pressure value of the vehicle seat is detected in real time. When the pressure value exceeds the pressure threshold, the electrolyte characteristic data of the fluid in the vehicle seat are collected through the fluid monitoring module installed in the vehicle seat.

[0026] Optionally, the target electrolyte data may include sodium ion concentration and potassium ion concentration; The identification module is specifically used to perform a weighted summation of sodium ion concentration and potassium ion concentration according to preset weight values ​​to obtain the sweat electrolyte index.

[0027] Optional, the recognition module is specifically used for: The product of sodium ion concentration and first weight value is determined as the first addend, the product of potassium ion concentration and second weight value is determined as the second addend, and the product of target ratio and third weight value is determined as the third addend; wherein, the target ratio is the ratio of sodium ion concentration to potassium ion concentration.

Detailed Implementation

[0037] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0038] Current vehicle cabin control methods typically adjust the control strategy adaptively based on cabin environment information. However, in scenarios such as high temperature, high humidity, traffic congestion, or aggressive driving, passengers are prone to sweating and feeling stuffy, and existing systems cannot promptly recognize these physiological changes, leading to decreased comfort and even increasing the risk of driver fatigue.

[0039] To address this issue, this disclosure provides a vehicle cabin control scheme. First, upon detecting sweat in a preset area within the vehicle cabin, the sweat electrolyte index for that area is determined based on the target electrolyte data of the sweat. This transforms the previously discrete sweat electrolyte information into a unified index, reducing the impact of fluctuations in the original data on the judgment results. Next, based on the sweat electrolyte index, a vehicle cabin control strategy is determined. This strategy adjusts environmental parameters within the vehicle cabin, establishing a mapping relationship between sweating rate and cabin control intensity, providing a tiered and adjustable basis for control decisions. Finally, the cabin control strategy is used to control the vehicle, enabling dynamic adjustments to the cabin environment based on changes in the user's physiological state, reducing the lag caused by manual intervention and fixed strategies. By incorporating the user's sweat electrolyte characteristics into the cabin control process, a physiologically-driven environmental regulation mechanism is formed, shifting cabin control from static rule-driven to state-aware-driven, thereby improving the continuity, adaptability, and overall user experience of the control.

[0040] The vehicle cabin control method provided in this disclosure is applicable to scenarios involving cabin environment adjustment in vehicles. This method can be executed by a vehicle cabin control device, which can be either hardware or software. When the vehicle cabin control device is hardware, it can be an electronic device with vehicle cabin control functions. When the vehicle cabin control device is software, it can be installed in the aforementioned electronic device. It can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are made here.

[0041] Based on the above application scenarios, in order to solve the technical problem of poor driving comfort in current vehicle cabin control solutions, this disclosure provides a vehicle cabin control method, such as... Figure 1 As shown, the method may include the following steps S11-S13: S11. When sweat is detected in a preset area in the vehicle cabin, the sweat electrolyte index of the preset area is determined based on the target electrolyte data of the sweat.

[0042] The preset area refers to the area in the vehicle cabin that the user comes into contact with. It refers to the human-machine interaction-related areas that can be directly touched, leaned on, or frequently approached by the driver or passengers during normal vehicle use. For example, the preset area may include, but is not limited to, seats, steering wheel, armrests, door trim panels, center console, touch screen housing, gear shift area, etc.

[0043] The sweat electrolyte index is used to characterize a user's sweating rate. It is a comprehensive indicator that reflects the rate at which the body sweats by quantifying electrolyte-related parameters in sweat. Generally speaking, under the same individual and physiological conditions, as the sweating rate increases, the concentration of the main electrolytes in sweat, represented by sodium ions, will increase accordingly. The faster the sweating rate, the higher the amount of sweat produced per unit time. Therefore, the sweat electrolyte index can also indirectly reflect a user's sweating level.

[0044] First, determine whether sweat is detected in a predetermined area within the vehicle cabin. Specifically, this can be done by receiving sweat detection data from other devices or systems, or by using a detection device placed near the predetermined area to detect the surface condition of that area.

[0045] Secondly, when sweat is detected in a preset area in the vehicle cabin, the sweat electrolyte index of the preset area is determined based on the target electrolyte data of the sweat.

[0046] Specifically, based on the target electrolyte data of sweat, the way to determine the sweat electrolyte index of a preset area can be by normalizing, weighting, or performing feature mapping on the target electrolyte data to generate a sweat electrolyte index that characterizes the sweating state of the preset area.

[0047] In some embodiments, the target electrolyte data includes sodium ion concentration and potassium ion concentration. The method for determining the sweat electrolyte index of a preset area based on the target electrolyte data of sweat can be to perform a weighted summation of the sodium ion concentration and potassium ion concentration according to preset weight values ​​to obtain the sweat electrolyte index.

[0048] Specifically, it can be done according to the formula: To calculate the sweat electrolyte index of a preset area. The sweat electrolyte index. This represents the sodium ion concentration. This refers to the potassium ion concentration. The weighting is based on the sodium ion concentration. The weighting is based on the potassium ion concentration. + =1, and and The value is preset, for example, it is a default value or a value set by relevant personnel according to the actual situation. For example, and .

[0049] By incorporating sodium and potassium ion concentrations from the target electrolyte data into the calculation of the sweat electrolyte index, and weighting and summing them according to preset weight values, the impact of different electrolyte components on sweating rate and fluid loss can be comprehensively reflected, avoiding the one-sidedness of a single ion indicator. Simultaneously, by setting weights, the role of key electrolytes can be highlighted based on actual application needs or statistical patterns, making the sweat electrolyte index adjustable and adaptable. This allows for a more accurate and stable representation of the user's sweating level, providing a quantitative and comparable decision-making basis for subsequent cabin control strategies based on the sweat electrolyte index, thus improving the rationality and precision of control strategy formulation.

[0050] In some embodiments, the sweat electrolyte index is obtained by weighted summation of sodium ion concentration and potassium ion concentration according to preset weight values. This can be achieved by first determining the first addend as the product of sodium ion concentration and a first weight value, the second addend as the product of potassium ion concentration and a second weight value, and the third addend as the product of a target ratio and a third weight value. Then, the sum of the first, second, and third addends is determined as the sweat electrolyte index. The target ratio is the ratio of sodium ion concentration to potassium ion concentration.

[0051] Specifically, it can be done according to the formula: To calculate the sweat electrolyte index of a preset area. The sweat electrolyte index. This represents the sodium ion concentration. This refers to the potassium ion concentration. The target ratio, The weight of sodium ion concentration (first weight value). This is the weight of the potassium ion concentration (second weight value). The weight of the target ratio (third weight value). + =1, and , as well as The value is preset, for example, it is the default value, or it is a value set by relevant personnel according to actual conditions (such as age, gender, historical data, etc.).

[0052] In some embodiments, due to differences in individual physiological characteristics, there are differences in sweating rate and sweat electrolyte distribution among people of different ages and genders. Generally, young men sweat faster and have relatively higher sodium ion concentrations in their sweat; middle-aged women, compared to middle-aged men, sweat at a relatively lower rate and have relatively lower sodium ion concentrations in their sweat; elderly individuals experience a decline in sweat gland function, resulting in a decrease in overall sweat volume, but their sweat sodium ion concentration tends to be higher, with significant individual variations. Furthermore, The weighting of sodium ion concentration is used to determine Sensitivity to sodium ion loss The weight of potassium ion concentration is used to determine Sensitivity to potassium ion loss In order to improve It is set for robustness, so it can be set to a small fixed value.

[0053] Therefore, in setting , as well as The value can be set according to the user's physiological characteristics; for example, it can be appropriately reduced for women and the elderly. For the elderly to improve , It can be set to a fixed small value. For example, when the user is a young male, set... 0.7 0.2 and Set to 0.1; when the user is an adult female, set to 0.5 0.3 and Set to 0.2; when the user is an elderly user, set to 0.4 0.4 and Set to 0.2; when the user is a teenager, set to 0.6 0.3 and It is 0.1.

[0054] In this way, by weighting sodium ion concentration, potassium ion concentration, and target ratio with their corresponding weight values, and then summing the weighted results to obtain the sweat electrolyte index, a comprehensive quantitative framework can be established to characterize multiple electrolyte-related features and their interrelationships. This reflects both the absolute change in the content of a single electrolyte and the influence of the proportional characteristics of different electrolytes on sweating rate. This method allows for flexible adjustment of the contribution of different features through weight configuration, reducing the sensitivity of the results to fluctuations in a single indicator. This makes the sweat electrolyte index more stable and discriminative, thus more accurately reflecting the user's actual sweating rate and providing a reliable basis for the subsequent refined and personalized adjustment of cabin control strategies.

[0055] In some embodiments, in order to ensure the accuracy of the calculated sweat electrolyte index, after obtaining the target electrolyte data of sweat, the target electrolyte data can be amplified, filtered, temperature compensated and calibrated to reduce the impact of environmental factors and acquisition errors on the electrolyte data, thereby improving the reliability of the sweat electrolyte index calculation.

[0056] S12. Determine the vehicle's cabin control strategy based on the sweat electrolyte index.

[0057] Cockpit control strategies are used to adjust environmental parameters within the vehicle cabin. Specifically, they refer to control schemes that dynamically adjust environmental parameters related to passenger comfort and safety. These environmental parameters can include temperature, humidity, airflow, airflow direction, odor, seat status, and display and interaction parameters. By implementing appropriate cockpit control strategies, the cabin environment can be matched to the user's current needs, thereby improving the passenger experience and overall comfort.

[0058] Specifically, the method for determining the vehicle's cabin control strategy based on the sweat electrolyte index can be as follows: First, select the target cabin control strategy based on the pre-stored correspondence between the sweat electrolyte index and cabin control strategies. Second, input the sweat electrolyte index into a preset strategy decision model and output the corresponding cabin control strategy. Third, first acquire multi-source information such as in-vehicle temperature and humidity, vehicle speed, sunlight intensity, and current air conditioning status, and then combine this information with the sweat electrolyte index to generate the vehicle's cabin control strategy.

[0059] S13. A cockpit control strategy is used to control the vehicle.

[0060] Specifically, the method of controlling the vehicle using a cockpit control strategy can be as follows: first, control commands are generated based on the cockpit control strategy; then, the vehicle's central control unit (ECU) controls the cockpit environment execution unit to execute the corresponding strategy via control signals, such as pulse width modulation (PWM) signals or controller area network (CAN) signals. The cockpit environment execution unit is an execution unit capable of adjusting environmental parameters; for example, it could be a seat ventilation fan (which may have multiple fan speeds), an air conditioning compressor, an air vent direction adjustment motor, or a seat heating element.

[0061] In the above scheme, firstly, when sweat is detected in a preset area within the vehicle cabin, the sweat electrolyte index for that area is determined based on the target electrolyte data of the sweat. The preset area is the region in the vehicle cabin that comes into contact with the user, and the sweat electrolyte index characterizes the user's sweating rate. Next, based on the sweat electrolyte index, a vehicle cabin control strategy is determined, which adjusts the environmental parameters within the vehicle cabin. Finally, the vehicle is controlled using the cabin control strategy. In this way, by identifying sweat in a preset area within the vehicle cabin and determining the sweat electrolyte index based on the target electrolyte data of the sweat, it is possible to effectively distinguish user sweat from other liquids that may be present in the cabin, avoiding interference from non-physiological liquids in judging the sweating rate, thereby ensuring the accuracy and reliability of determining the sweat electrolyte index. Based on this, the sweat electrolyte index is incorporated into the cabin control strategy determination process, so that the adjustment of vehicle cabin environmental parameters no longer depends solely on the external environment or fixed thresholds, but matches the user's actual sweating rate. This enables the perception and response to the user's physiological state, minimizing inconsistencies between cabin environment adjustment and user experience, improving the precision of cabin environment adjustment, and thus enhancing vehicle cabin comfort and the overall driving experience.

[0062] In some embodiments, such as Figure 2 As shown, the method for identifying sweat in a preset area in the vehicle cabin in step S1 above may include the following steps S01-S02.

[0063] S01. Collect electrolyte characteristic data of liquid in a preset area in the vehicle cabin.

[0064] The electrolyte characteristic data include the concentration of sodium ions and potassium ions in the liquid, the temperature of the liquid, and the rate of increase in the liquid's conductivity.

[0065] Specifically, a detection device positioned near a preset area can be used to detect electrolyte-related parameters in a liquid and output corresponding electrolyte characteristic data. This detection device can include one or more of an electrochemical sensor, a conductivity detection unit, or a microfluidic detection module, used to acquire the ion concentration, conductivity, electrochemical potential, or combinations thereof of the electrolyte in the liquid.

[0066] S02. When the electrolyte characteristic data meets the following conditions, determine that sweat is detected in a preset area in the vehicle cabin, and determine the electrolyte characteristic data as the target electrolyte data of the user's sweat in the vehicle.

[0067] During vehicle use, in addition to sweat, beverages, rainwater, or other liquids may be present in the cabin, such as spilled drinking water or moisture brought in when entering or exiting the vehicle in rainy weather. If these liquids from different sources are not distinguished, they can easily be misidentified as sweat, leading to deviations in subsequent electrolyte characteristic data collection, sweat electrolyte index calculation, and cabin control strategy determination, ultimately resulting in unnecessary or unreasonable cabin environment adjustments. Therefore, distinguishing sweat from other liquids helps improve the overall reliability of vehicle cabin control.

[0068] The electrolyte ion concentration, secretion rate, pH value, and temperature of sweat are significantly different from those of other liquids. For example, the sodium ion concentration in sweat is typically 20–80 mmol / L, and the potassium ion concentration is typically 3–15 mmol / L; while the electrolyte ion concentration in tap water is typically 0, and the electrolyte ion concentration in beverages is usually a fixed formula (e.g., sports drinks contain approximately 20 mmol / L of sodium ions, but extremely low concentrations of potassium ions). The secretion rate of sweat is typically slow and continuous, such as 0.1–5 μL / min·cm², and varies gradually with heat stress; while other liquids are typically sprayed instantaneously (i.e., rate >100 μL / ms) and lack a physiological rhythm. The pH value of sweat is weakly acidic (4.5–6.5); the pH value of other liquids is typically neutral (pH≈7) or alkaline (e.g., soda water). Sweat has a temperature close to that of the human body surface, such as 32–36 degrees Celsius (°C); other liquids are usually at ambient temperature (e.g., iced drinks ≈ 5°C, hot water ≈ 60°C). Sweat typically appears in areas of skin contact (e.g., shoulder blades on backrests, buttocks on seat cushions); other liquids can appear anywhere (e.g., armrests, headrests).

[0069] Therefore, sweat can be identified by the following conditions: sodium ion concentration is greater than or equal to the first threshold (e.g., 15 mmol / L), potassium ion concentration is greater than or equal to the second threshold (e.g., 2 mmol / L), the liquid temperature is within a preset temperature range (e.g., 30–38°C), and the rate of increase of the liquid's conductivity is less than a preset rate threshold, such as a rate of increase of conductivity less than 0.5 millisiemens per centimeter per second (mS / cm / s).

[0070] In some embodiments, when the liquid is identified as not being sweat, the location, time, and extent of the liquid spill are recorded, or a liquid spill notification is sent.

[0071] In the above scheme, multi-dimensional electrolyte characteristic data such as sodium ion concentration, potassium ion concentration, liquid temperature, and conductivity rise rate are collected from the liquid in a preset area of ​​the vehicle cabin. The liquid is identified as user sweat only when the above characteristics simultaneously meet preset conditions. This scheme can comprehensively constrain the liquid type from multiple dimensions such as composition characteristics, thermal characteristics, and dynamic change characteristics, effectively distinguishing sweat from non-physiological liquids such as water and beverages, significantly reducing the probability of misidentification. This ensures the authenticity and stability of the target electrolyte data source, providing a reliable data foundation for the accurate calculation of sweat electrolyte index and the formulation of cabin control strategies based on user physiological state, thereby improving the credibility and robustness of the overall control decision.

[0072] In some embodiments, the preset area may be the area where the steering wheel is located or the area where the vehicle seat is located. The method of collecting electrolyte characteristic data of the liquid in the preset area of ​​the vehicle cabin in S01 above may be to collect electrolyte characteristic data of the liquid in the vehicle seat through a liquid monitoring module installed in the vehicle seat; and / or to collect electrolyte characteristic data of the liquid on the vehicle steering wheel through a liquid monitoring module installed in the vehicle steering wheel.

[0073] Specifically, the liquid monitoring module can be integrated into the seat back and / or seat cushion surface, or the steering wheel surface. It is encapsulated in a flexible, breathable, and skin-friendly material as a flexible sensing patch. This patch can consist of a polydimethylsiloxane (PDMS) microfluidic layer, a silver / silver chloride (Ag / AgCl) reference electrode, an ion-sensitive field-effect transistor (ISFET) sodium / potassium ion sensor (hereinafter referred to as the ISFET sensor), and a Bluetooth Low Energy (BLE) transmission module.

[0074] The PDMS microfluidic layer, also known as a "micro-highway for sweat," is made into a thin film with tiny grooves and attached to the surface of a pre-defined area. When the occupant sweats, the sweat automatically flows along these tiny grooves (through capillary action, without a pump), ultimately guiding the sweat to the sensor location, much like rainwater flowing from the eaves into a bucket. In simpler terms, it's like burying a "micro-drainage network" in the pre-defined area to ensure effective sweat delivery to the sensing region. The Ag / AgCl reference electrode is used to measure the concentration of all ions, such as sodium ions (Na+). + ), potassium ions (K) + All of these require a stable voltage reference point, just as weighing oneself requires "zeroing out." The Ag / AgCl electrode provides this stable and unchanging "zero voltage," allowing the ISFET sensor to accurately read Na. + / K + The resulting voltage change. Without a reference electrode, the voltage measured by an ISFET is "floating" and cannot be converted into a true concentration; it's like using an uncalibrated thermometer that shows "30 degrees," but you don't know if it's Celsius or Fahrenheit. An ISFET sensor is a device that can detect the concentration of specific ions (such as Na+) in a solution. + K + A miniature semiconductor sensor that directly converts signals into electrical signals (voltage / current) is essentially a specially designed microchip with a surface coated with Na+. + or K + Sensitive materials, when sweat comes into contact with the chip surface: Na + It will change the current of the sodium-ISFET; K + This changes the current in the potassium-ISFET; these current changes are converted into a digital signal representing "how much sodium / potassium is in the sweat". The BLE transmission module is used to transmit the sodium measured by the ISFET sensor. + / K + Data is sent to the vehicle system without the need for complex wiring, making installation simpler and more reliable.

[0075] For example, such as Figure 3The diagram shows a schematic of the PDMS microfluidic layer on the surface of a liquid monitoring module according to an embodiment of this disclosure. The PDMS microfluidic layer 20 has multiple uniformly distributed micropores 21 on its surface, with a diameter that can be set to 0.4 mm. It also has multiple radial microchannels (such as those corresponding to 22, 23, 24, and 25), with a channel depth that can be set to 50 μm. The intersection of the microchannels can be defined as the central convergence point. A polyimide (PI) flexible circuit is positioned directly below the central convergence point, and this circuit includes an ISFET sensor. The PI flexible circuit includes an Ag / AgCl reference electrode window (exposed to the channel outlet), followed by an open-cell polyurethane foam (with openings aligned with the sensing area), and a leak-proof membrane at the bottom.

[0076] PI is a high-performance flexible polymer film that is heat-resistant (>300°C), bend-resistant, and has good insulation. It is often used in flexible electronics (such as circuit boards for foldable mobile phone screens). PI flexible circuits are made by printing or integrating Na on PI films. + Selective ISFET, K + The system includes a selective ISFET, an Ag / AgCl reference electrode (providing an electrochemical reference), and signal traces (connected to an external processing unit). Open-cell PU foam protects the liquid monitoring module from damage; PU foam is the high-resilience sponge commonly found in car seats, offering softness, breathability, and support. The open-cell design refers to the interconnected porous structure within the foam (not closed air bubbles), allowing air and moisture to pass through. The opening is aligned with the sensing area; a small hole is pre-drilled in the PU foam corresponding to the ISFET sensor location above it to ensure no material compression in that area.

[0077] In some embodiments, this disclosure does not limit the size and shape of the liquid monitoring module; for example, it can be as follows: Figure 3 The rectangle shown can also be a circle, a polygon, etc.

[0078] In the above solution, the preset areas are set as the steering wheel area and / or the vehicle seat area. Liquid electrolyte characteristic data for these areas are collected by liquid monitoring modules installed on the vehicle seat or steering wheel. This leverages the fact that these areas are in long-term, direct contact with the user's body, improving the correlation and accuracy between liquid collection and user sweat, and reducing misjudgments due to unknown liquid sources. Simultaneously, by independently or in combination monitoring multiple high-frequency contact areas, multi-point perception and cross-verification of the user's sweating status can be achieved, enhancing the stability and comprehensiveness of sweat recognition results. This provides a more reliable input for subsequent cabin control based on sweat electrolyte data, improving the accuracy of cabin environment adjustment and user comfort.

[0079] In some embodiments, such as Figure 4 As shown, before the liquid monitoring module installed in the vehicle seat collects the electrolyte characteristic data of the liquid in the vehicle seat, the vehicle cabin control method may also include the following steps S21-S22.

[0080] S21. Real-time detection of vehicle seat pressure values.

[0081] Specifically, pressure detection devices installed inside or on the surface of vehicle seats can continuously collect data on the forces or pressure distribution acting on the seats and convert the collected signals into corresponding pressure values. These pressure detection devices can include piezoresistive, piezoelectric, capacitive pressure sensors, or combinations thereof, thereby enabling real-time detection of seat pressure values.

[0082] S22. When the pressure value is greater than the pressure threshold, the electrolyte characteristic data of the liquid in the vehicle seat is collected through the liquid monitoring module installed in the vehicle seat.

[0083] The pressure threshold is a preset value, such as a default value or a value set by relevant personnel based on the weight of a sedentary person. For example, the pressure threshold is the pressure value at 20 kg.

[0084] Since human sweat can only be collected from vehicle seats when occupants are seated, the presence of occupants can be determined by detecting the seat pressure value in real time. The sweat detection process can then be initiated only when the seat pressure value meets the preset occupant condition, thus avoiding invalid detection operations when no one is present and reducing system resource consumption.

[0085] In the above-described scheme, the pressure value of the vehicle seat is monitored in real time before collecting electrolyte characteristic data of the fluid. Data collection is only triggered when the pressure value exceeds a preset threshold, ensuring the vehicle seat is in a state where the user is actually seated. This avoids invalid collection of environmental or residual fluids when no one is seated or there is only slight contact, reducing the probability of false sampling and misjudgment. Furthermore, by combining pressure triggering conditions with the fluid collection process, this method improves the correlation and timeliness between electrolyte characteristic data and the user's physiological state, reduces unnecessary detection energy consumption, and provides a more reliable and high-quality data foundation for subsequent sweat recognition and accurate formulation of cabin control strategies.

[0086] In some embodiments, such as Figure 5 As shown, the method of determining the vehicle's cabin control strategy based on the sweat electrolyte index in S12 above may include the following steps S121-S125.

[0087] S121. Determine whether the sweat electrolyte index is less than or equal to the first index threshold. If the sweat electrolyte index is less than or equal to the first index threshold, proceed to step S122. If the sweat electrolyte index is greater than the first index threshold, proceed to step S123.

[0088] The first index threshold is a preset value, such as a default value or a value set by relevant personnel based on actual circumstances. For example, the first index threshold is 20.

[0089] S122, Maintain the current cockpit control strategy.

[0090] If the sweat electrolyte index is low, it means that the sweating rate is slow. The current environment is then determined to be "comfortable," and the current cabin control strategy is maintained to preserve the current environment.

[0091] S123. Determine whether the sweat electrolyte index is less than or equal to the second index threshold. If the sweat electrolyte index is less than or equal to the second index threshold, proceed to step S124. If the sweat electrolyte index is greater than the second index threshold, proceed to step S125.

[0092] The second index threshold is a preset value, such as a default value or a value set by relevant personnel based on actual circumstances. For example, the second index threshold is 35.

[0093] S124. Lower the heating level to the first preset level, or increase the fan ventilation level to the first preset level.

[0094] The first preset level is a preset value, such as a default value or a value set by relevant personnel according to the actual situation.

[0095] If the sweat electrolyte index is slightly high, it indicates that the sweating rate is faster, and it is judged as "mild sweating". At this time, if the heating function is turned on (such as seat heating, steering wheel heating, air conditioning hot air, etc.), the heating level should be reduced to the first preset level. If the heating function is not turned on, the fan ventilation level should be increased to the first preset level (including increasing the fan speed, or turning the fan on from a standby state).

[0096] S125. Turn off the heating function, or adjust the fan ventilation level to the highest level and lower the air conditioning temperature to the preset temperature threshold.

[0097] The preset temperature threshold is a pre-defined value, such as a default value or a value set by relevant personnel based on actual conditions. For example, the preset temperature threshold is 2–3℃.

[0098] If the sweat electrolyte index is extremely high, it indicates rapid sweating, which is considered "excessive sweating." In this case, if the heating function is on, turn it off. If the heating function is not on, adjust the fan ventilation level to the highest setting (including increasing the fan speed to the maximum, or turning the fan from a standstill to the highest setting), and simultaneously lower the air conditioner temperature to the preset threshold.

[0099] In the aforementioned solution, by dividing the sweat electrolyte index into multiple ranges and corresponding to different levels of cabin control strategies, the cabin environment can be adjusted in a graded and gradual manner based on changes in the user's sweating rate. When the sweating rate is low, the current control strategy is maintained to avoid discomfort and increased energy consumption caused by frequent adjustments; when the sweating rate is moderate, the heating level is appropriately reduced or the ventilation level is increased to achieve gentle intervention, balancing comfort and energy efficiency; when the sweating rate is high, stronger cooling and ventilation measures are taken to quickly improve the cabin thermal environment. This graded control method establishes a clear correspondence between cabin environment adjustment and the user's physiological state, improving the rationality and continuity of control response, reducing the occurrence of over- or under-adjustment, thereby improving cabin comfort and the overall driving experience.

[0100] In some embodiments, such as Figure 6 As shown, the vehicle cabin control method may also include the following steps S141-S143.

[0101] S141. Collect user feedback within a preset time period after the vehicle is controlled using the cockpit control strategy.

[0102] Specifically, proactive feedback from users can be obtained through the human-computer interaction interface, or indirect feedback data reflecting user satisfaction or comfort can be obtained by monitoring user behavior characteristics or changes in cabin status. Of course, the two can be used alone or in combination.

[0103] S142. When the user feedback is negative, increase the values ​​of the first exponential threshold and the second exponential threshold by the first value.

[0104] The value of the first value should be less than the first preset ratio of the first index threshold, and the values ​​of the first index threshold and the second index threshold should be controlled within a preset range to avoid the continuous rise of the threshold causing the cockpit control function to become too sluggish, thereby reducing the timeliness of response to changes in user status and affecting the user experience.

[0105] When user feedback is negative, it indicates that the user perceives the vehicle's cabin control functions to be overly sensitive. In this case, the impact of changes in sweat electrolyte levels on cabin control strategy triggering can be reduced by simultaneously increasing both the first and second index thresholds. This reduces the overall sensitivity of the vehicle's cabin control functions, making the control behavior more aligned with user habits.

[0106] S143. When the user feedback is positive, decrease the values ​​of the first exponential threshold and the second exponential threshold by the second value.

[0107] The value of the second value should be less than the second preset ratio of the first index threshold, and the values ​​of the first index threshold and the second index threshold should be controlled within a preset range to avoid the continuous decrease of the threshold causing the cockpit control function to become oversensitive, thereby causing frequent control or false triggering problems, affecting user experience and system stability.

[0108] Similarly, when user feedback is positive, it indicates that the user is relatively satisfied with the response of the vehicle's cabin control functions. In this case, by appropriately lowering both the first and second index thresholds, the sensitivity of changes in sweat electrolyte levels to cabin control strategies can be increased, making cabin control more timely and thus further aligning the control behavior with the user's habits.

[0109] In some embodiments, when the user feedback is no feedback, the values ​​of the first exponential threshold and the second exponential threshold are not changed.

[0110] In the above scheme, a user feedback mechanism is introduced within a preset time period after the cabin control strategy is executed. Based on the feedback results, the first and second index thresholds are dynamically adjusted, enabling the mapping relationship between the sweat electrolyte index and the cabin control strategy to have adaptive optimization capabilities. When the user provides negative feedback, raising the threshold reduces the sensitivity of the control strategy triggering, avoiding over-adjustment; when the user provides positive feedback, lowering the threshold improves the system's responsiveness to changes in sweating status, making the control strategy more aligned with the user's subjective comfort. This approach achieves closed-loop adjustment based on user experience, continuously refining control parameters and gradually bringing the cabin control strategy towards a personalized and optimal state, thereby improving comfort stability and user satisfaction during long-term use.

[0111] In some embodiments, after the vehicle is controlled using a cockpit control strategy, the vehicle cockpit control method may further include controlling the display of prompt information on the in-vehicle screen.

[0112] The notification messages are used to indicate that the cabin control strategies have taken effect. For example, the in-vehicle screen may display a notification such as: "We have detected that you may be sweating a lot. We have increased ventilation and cooled you down," "We recommend that you drink water," or "The current cabin has been optimized."

[0113] In the above solution, after the vehicle is controlled using the cockpit control strategy, a prompt message is displayed on the in-vehicle screen to indicate that the cockpit control strategy has taken effect. This provides intuitive feedback on the automatic adjustment results to the user, enhancing the user's perception of the reasons and status of changes in the cockpit environment and preventing user confusion or misoperation due to changes in environmental parameters. Simultaneously, this prompt mechanism helps improve the transparency and explainability of human-machine interaction, allowing users to understand the system's working status in a timely manner, enhancing their trust and sense of control over the automatic adjustment functions, thereby improving the overall cockpit interaction experience and user satisfaction.

[0114] In some embodiments, the vehicle cabin control scheme of this disclosure supports users manually overriding the automatic mode.

[0115] In some embodiments, the vehicle cabin control method further includes collecting target electrolyte data of sweat at a preset location in the vehicle at a preset frequency (e.g., 0.2 Hz) through a liquid monitoring module located near a preset location in the vehicle.

[0116] In some embodiments, when sweat is detected, the ISFET sensor uploads target electrolyte data to the control unit (which may be the vehicle ECU) once every preset time period (e.g., 5 seconds).

[0117] This disclosed vehicle cabin control solution uses sweat electrolytes as the core input for cabin environment regulation, achieving "human sensation-based control." Sensors are fully embedded in the seats, eliminating the need for users to wear additional equipment and improving usability. It also reduces decreased attention due to heat and dehydration, lowering the risk of accidents. Ventilation / cooling is activated only when needed, avoiding unnecessary energy consumption. Furthermore, it can integrate with health management systems and autonomous driving systems to build a next-generation intelligent cabin ecosystem.

[0118] This disclosure embodiment can divide the vehicle cockpit control device into functional modules according to the above method example. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing unit. The integrated modules can be implemented in hardware or as software functional modules. It should be noted that the module division in this disclosure embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.
