On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0053] Embodiment 1
[0054] See Figure 1 , an adaptive control method for ventilation and heating of an automotive seat in this embodiment includes:
[0055] Step S100: Real-time obtain the environmental parameters of the automotive seat to be measured;
[0056] The environmental parameters include: seat temperature, seat humidity, air flow velocity, passenger skin temperature, and passenger skin conductivity;
[0057] Step S200: Input the environmental parameters of the automotive seat to be measured into the trained comfort index acquisition model to obtain the comfort index of the automotive seat to be measured;

[0059] The parameter acquisition model includes: a heating power acquisition sub-model and a ventilation intensity acquisition sub-model.
[0060] In the specific implementation process, environmental parameters are obtained through different sensors; for example, a temperature sensor is used to detect the passenger skin temperature and the seat temperature, a humidity sensor is used to detect the seat humidity, an air flow sensor is used to detect the air flow velocity, and a skin conductivity sensor is used to detect the passenger skin conductivity.
[0061] An adaptive control method for ventilation and heating of an automotive seat in this embodiment improves the comfort of passengers during riding, and at the same time precisely adjusts heating and ventilation, avoiding waste of energy, reflecting the perfect combination of the humanized and environmental protection concepts of modern automobiles.
[0062] Embodiment 2
[0063] An adaptive control method for ventilation and heating of an automotive seat in this embodiment includes:
[0064] Step S100: Real-time obtain the environmental parameters of the automotive seat to be measured;
[0065] The environmental parameters include: seat temperature, seat humidity, air flow velocity, passenger skin temperature, and passenger skin conductivity;
[0066] Step S200: Input the environmental parameters of the automobile seat to be measured into the trained comfort index acquisition model to obtain the comfort index of the automobile seat to be measured;
[0067] Step S300: When the comfort index is less than the pre-set threshold, input the environmental parameters of the automobile seat to be measured into the parameter acquisition model to obtain the relevant adjustment parameters of the automobile seat;
[0068] The parameter acquisition model includes: a heating power acquisition sub-model and a ventilation intensity acquisition sub-model.
[0069] In step S200, the comfort index acquisition model includes:
[0070] A data input layer, which is used to receive the environmental parameters of the automobile seat to be measured;
[0071] A feature engineering layer, which is used to perform data preprocessing on the environmental parameters of the automobile seat to be measured to obtain the processed data;
[0072] A deep learning feature extraction layer, which is used to use a deep neural network to extract features from the processed data to obtain high-level features and obtain a first comfort index;
[0073] A fuzzy logic inference layer, which is used to obtain a second comfort index according to the high-level features and the pre-constructed fuzzy rule base;
[0074] A fusion adjustment layer, which is used to combine the first comfort index and the second comfort index to obtain the comfort index.
[0075] An output layer, which is used to output the comfort data of the automobile seat to be measured.
[0076] In the specific implementation process, the feature engineering layer processes the environmental parameters of the automobile seat to be measured received by the data input layer; for example, the environmental parameters are scaled to the same scale using the Z-score normalization method:
[0077] For each environmental parameter, its Z-score normalized value z i can be calculated by the following method:
[0078]
[0079] where xi is the original feature value, μ is the average value of all sample values of this feature, and σ is the standard deviation of all sample values of this feature.
[0080] Further, in practical applications, before data standardization, it is also necessary to remove error values, missing values, or duplicate values from the environmental parameters. For example, if the temperature data at a certain moment is significantly incorrect, it is corrected or deleted.
[0081] In this embodiment, the deep learning feature extraction layer includes: a fully connected layer, a convolutional layer, a recurrent layer, an attention mechanism, and a regularization layer. The deep learning feature extraction layer uses a deep neural network to extract high-level features from the processed environmental parameters. These features are usually high-level abstract representations of the original data and can capture complex patterns and relationships in the data.
[0082] In the fuzzy logic inference layer, first, based on the high-level features output by the deep learning feature extraction layer and the pre-constructed fuzzy rule base, a fuzzification process is performed. The fuzzy rule base contains a series of fuzzy rules constructed based on expert knowledge and experience, which define the fuzzy relationships between different feature values and the comfort index. The fuzzy logic inference layer uses these rules for reasoning, obtains the membership degree of the fuzzy set through the triangular membership function, and minimizes the membership degree to calculate the fuzzy comfort index. The reasoning process may involve operations on fuzzy sets (such as union, intersection, complement, etc.) and the calculation of fuzzy implication relationships.
[0083] To convert the fuzzy comfort index into an exact numerical value, the fuzzy logic inference layer also includes a defuzzification step. The purpose of defuzzification is to select one or several most representative values as the exact representation of the comfort index according to the membership function of the fuzzy set. Defuzzification methods may include the centroid method, the maximum membership degree method, or the weighted average method, etc.
[0084] For example, in the fuzzy logic inference layer, the pre-constructed fuzzy rule base includes:
[0085] Seat temperature: T seat <20°C, fuzzified as cold; 18°C < T seat <25°C, fuzzified as cool; 25°C < T seat <30°C, fuzzified as warm; T seat >27°C, fuzzified as hot;
[0086] Seat humidity: Hs < 40%, fuzzified as dry; 40% < Hs < 60%, fuzzified as moderate; Hs > 60%, fuzzified as humid;
[0087] Airflow velocity: V a <0.1, fuzzified as calm; 0.1 < V a <0.5, fuzzified as gentle breeze; V a > 0.5, fuzzified as strong wind;
[0088] Passenger skin temperature: Tskin < 33 °C, it is fuzzy as low; 33 < T skin < 36 °C, it is fuzzy as normal; T skin > 36 °C, it is fuzzy as high;
[0089] Passenger skin conductivity: G skin < 5, it is fuzzy as low; 5 < G skin < 8, it is fuzzy as medium, G skin > 8, it is fuzzy as high.
[0090] Rule 1: If the seat temperature is cold and the humidity is dry, the comfort level is very uncomfortable.
[0091] Rule 2: If the seat temperature is cool and the humidity is moderate, the comfort level is relatively comfortable.
[0092] Rule 3: If the air flow speed is gentle breeze and the passenger skin temperature is normal, the comfort level is average.
[0093] Rule 4: If the passenger skin conductivity is high and the seat temperature is hot, the comfort level is not very comfortable.
[0094] In this embodiment, after obtaining the first comfort index output by the deep learning feature extraction layer and the second comfort index output by the fuzzy logic inference layer, the final comfort index is obtained by weighted average.
[0095] In this embodiment, in step S200,
[0096] The trained comfort index acquisition model is a model trained by an asynchronous training method according to the historical data set;
[0097] The historical data set includes: historical environmental parameters and the comfort index corresponding to each historical environmental parameter.
[0098] Specifically, asynchronous training means that in a distributed computing environment, multiple worker nodes train the model in parallel, but each node independently updates the model parameters without waiting for other nodes to complete the current iteration process. By adopting asynchronous training, the idle time caused by synchronous waiting can be significantly reduced, thereby improving the overall training speed.
[0099] In the specific usage process, first, the historical data set is divided into several subsets, and these subsets are assigned to different worker nodes. Each node is responsible for processing the data of one or more subsets and updating the model parameters based on this data; that is, each node independently trains according to the data subset it receives and is not affected by the progress of other nodes.
[0100] After every 10 iterations are completed, each node updates its model parameters to the central server or aggregates and averages these model parameters using a parameter server architecture to obtain a new global model.
[0101] In summary, adopting an asynchronous training method for constructing a comfort index acquisition model for car seats can not only speed up the training process, but also better adapt to various situations that may occur in practical applications, ensuring the accuracy and practicality of the comfort index acquisition model.
[0102] In this embodiment, in step S300, when the comfort index is less than a preset threshold, it specifically includes:
[0103] Step S310: Input the environmental parameters of the car seat to be measured into the heating power acquisition sub-model to obtain the heating power of the car seat;
[0104] Step S320: Input the environmental parameters of the car seat to be measured into the ventilation intensity acquisition sub-model to obtain the ventilation intensity acquisition sub-model of the car seat.
[0105] When the comfort index is greater than or equal to the preset threshold, heating and ventilation are not performed, that is, both the heating power and the ventilation intensity are 0.
[0106] In the specific implementation process, the preset threshold is dynamically adjusted according to the season or climate conditions. For example, if the range of the comfort index is 0 - 100 and the initial basic threshold is set to 70, when the comfort index is lower than 70, the heating and ventilation functions are activated.
[0107] In winter, due to the low environmental temperature and the high demand for the heating function by users, the threshold is adjusted to 65; in spring and autumn, the environmental temperature is relatively suitable and the demand for heating or ventilation by users is low, so the basic threshold is maintained; in summer, due to the high environmental temperature and the high demand for the ventilation function by users, the threshold is appropriately lowered and adjusted to 65.
[0108] Furthermore, when the environmental temperature is lower than 10°C, the threshold is further lowered by 3; when the environmental temperature is higher than 30°C, the threshold is further lowered by 3; when the environmental humidity is higher than 70%, the threshold is lowered by 2; when the environmental humidity is lower than 30%, the threshold is further lowered by 3.
[0109] Furthermore, the threshold set in this embodiment can also be manually adjusted and modified by the user.
[0110] In this embodiment, step S310 specifically includes:
[0111] Input the environmental parameters of the car seat to be measured into the following formula to obtain the heating power of the car seat:
[0112]
[0113] Among them, P is the heating power, and T skin is the passenger's skin temperature, T seat is the seat temperature, CI is the comfort index, and G skin is the passenger's skin conductivity, and α, β, and γ are weight coefficients.
[0114] In a specific implementation process, if the environmental parameters of the automobile seat to be tested are input into the following formula, and if the obtained heating power is negative, no heating is performed, that is, the heating power is set to 0.
[0115] Further, step S320 includes:
[0116] Input the environmental parameters of the automobile seat to be tested into the following formula to obtain the ventilation intensity of the automobile seat:
[0117]
[0118] Among them, I vent is the ventilation intensity, V a is the air flow velocity, H s is the seat humidity, H max is the maximum seat humidity, G skin is the passenger's skin conductivity, CI target is the pre-set comfort index threshold, CI is the comfort index, and the γ1, γ2, γ3, and γ4 are weight parameters to be optimized, which are obtained by training the ventilation intensity acquisition sub-model using historical environmental parameters and the corresponding ventilation intensity.
[0119] The method of this embodiment further includes:
[0120] Step S400: Real-time monitor the environmental parameters and comfort index of the seat to be tested after adjustment. If the comfort index is still lower than the pre-set threshold, repeat step S300 until the comfort index is greater than the pre-set threshold.
[0121] This embodiment is a closed-loop feedback control system, which enables the effect after each adjustment to be evaluated in a timely manner, and further optimizes the heating power and ventilation intensity according to the results until the requirements of the comfort index are met. Through the above operations, not only can it ensure that when the comfort index is lower than the set threshold, it can effectively trigger and execute the corresponding adjustment process, but also can effectively reduce resource waste and achieve an efficient and comfortable user experience.
[0122] Step S500: Add the environmental parameters of the vehicle seat to be measured and the comfort index of the vehicle seat to be measured to the historical data set, continuously train the comfort index acquisition model, and obtain the optimized comfort index acquisition model as the comfort index acquisition model for the next use.
[0123] In this embodiment, by continuously updating the comfort index acquisition model and using it as the comfort index acquisition model for the next use, the accuracy of the comfort index acquisition model can be continuously improved, thus better meeting the actual needs of vehicle seat comfort evaluation.
[0124] An adaptive control method for vehicle seat ventilation and heating in this embodiment can not only significantly improve the riding experience of passengers, but also has the advantages of energy conservation, environmental protection, and intelligent operation.
