[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The method for evaluating the contribution of automobile interior decoration parts to the odor in the vehicle provided in the embodiment of the present application can be applied in the application environment shown in FIG1 . The terminal 102 communicates with the server 104 through a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers.

[0053] The terminal 102 obtains a first subjective evaluation average value of the odor intensity of each interior decoration component in the odor screening simulation cabin; when the automobile assembly components in the cabin are removed, a first objective evaluation value and a second subjective evaluation average value of the odor intensity of each interior decoration component in the odor screening simulation cabin are obtained; the server 104 is used to evaluate the odor contribution of each interior decoration component based on the first subjective evaluation average value, the first objective evaluation value and the second subjective evaluation average value of the odor intensity.

[0054] The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The server 104 may be an independent physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides cloud computing services.

[0055] In an exemplary embodiment, as shown in FIG2 , a method for evaluating the contribution of automobile interior decoration parts to the odor in the vehicle is provided, and the method is applied to the server in FIG1 as an example for explanation, including the following steps S202 to S208. Among them:

[0056] Step S202, according to the actual position of the interior parts in the car, all the interior parts are arranged in the odor screening simulation cabin, according to the actual volume of the car, the volume of the odor screening simulation cabin is adjusted, and the test temperature, test humidity and test duration of the odor screening simulation cabin are set.

[0057] Specifically, all interior parts are arranged in the odor screening simulation cabin according to their actual positions in the car. This is done to ensure that the environment in the simulation cabin is as close as possible to the conditions inside the actual vehicle. For example, interior parts such as carpets, ceilings, and seats should be placed in the corresponding positions in the simulation cabin. The volume of the odor screening simulation cabin is adjusted according to the actual volume of the car. This is to ensure that the ratio of the space in the simulation cabin is consistent with the actual vehicle space, so that the odor distribution and concentration simulation is more accurate.

[0058] The test temperature, humidity and duration of the odor screening simulation chamber are set. These parameters have an important impact on the release and volatilization of odor substances. Higher temperatures usually accelerate the release of odor substances, and changes in humidity will also affect the release of odor substances in the material. The set test duration should be long enough to ensure that the odor substances have enough time to release and volatilize, thereby simulating the actual use situation.

[0059] Step S204, obtaining a first subjective evaluation average value of the odor intensity of each interior decoration component in the odor screening simulation cabin.

[0060] Specifically, according to the content of the attachment, obtaining the first subjective evaluation average of the odor intensity of each interior part in the odor screening simulation cabin means evaluating the odor in the simulation cabin through human olfactory senses and calculating the average of the odor intensity levels given by all evaluators. This step is the subjective evaluation part of the odor contribution evaluation method, which is specifically understood as follows:

[0061] Subjective evaluation is to capture people's direct feelings about odor, because some odor substances may be detected at low concentrations, and instruments may not be able to detect or accurately reflect people's actual feelings. Usually composed of five or more trained odor evaluators who can make standardized evaluations of odors.

[0062] The evaluator evaluates the odor intensity using an olfactory cup connected to the outlet of the electronic nose. During the evaluation process, the evaluator will adjust the dilution factor and record the odor intensity and corresponding TVOC value at different dilution factors. The odor intensity level given by the evaluator is determined based on the perceived intensity of the odor, and is usually divided into several levels, such as from "no odor" to "very strong" odor. The evaluation results of all evaluators on the same odor sample are collected and the average value is calculated. This average value represents the first subjective evaluation average of the odor intensity of the interior part in the simulated cabin.

[0063] Step S206, obtaining a first objective evaluation value and a second subjective evaluation average value of the odor intensity of each interior decoration component in the odor screening simulation cabin, while removing the automobile assembly components in the cabin.

[0064] Specifically, in the odor screening simulation cabin, specific automotive assembly parts, such as seats, carpets, dashboards, etc., are first removed in order to evaluate the odor contribution of the remaining interior parts separately. The odor samples in the simulation cabin are tested using instruments such as electronic noses to obtain the first objective evaluation value. This value is obtained by the instrument according to the preset model and algorithm, reflecting the odor intensity of the remaining interior parts after removing specific assembly parts.

[0065] After removing the specific assembly parts, the odor evaluation team conducted another subjective evaluation of the odor in the simulated cabin. The evaluators evaluated the odor through the olfactory port, and the second subjective evaluation average value obtained was the average of the evaluation results of all evaluators. This average value reflects the odor intensity of the remaining interior parts when the specific assembly parts are not present.

[0066] Step S208 , evaluating the odor contribution of each interior component according to the first subjective evaluation average value, the first objective evaluation value, and the second subjective evaluation average value of the odor intensity.

[0067] Specifically, the first subjective evaluation average is the average of the subjective odor intensity evaluations conducted by the odor evaluation team when all interior parts are placed in the odor screening simulation cabin according to the actual layout in the car. This value reflects the overall contribution of all interior parts to the odor in the car.

[0068] The first objective evaluation average is the odor intensity value obtained under the same conditions using objective instruments such as electronic noses. This value provides objective data based on instrument measurement, which is used to verify and supplement the subjective evaluation results.

[0069] The second subjective evaluation average is the average of the subjective odor intensity evaluations of the remaining interior parts after the specific interior assembly parts are removed. By comparing the first subjective evaluation average and the second subjective evaluation average, the odor contribution of the removed parts can be evaluated. By calculating the difference between the first subjective evaluation average and the second subjective evaluation average, the contribution of a specific interior part to the odor in the car can be determined. If the first subjective evaluation average is significantly higher than the second subjective evaluation average, this indicates that the removed interior part has a significant impact on the odor in the car. At the same time, the first objective evaluation value provides an independent, instrumentally measured odor intensity benchmark that can be used to verify the accuracy of the subjective evaluation and ensure the reliability of the evaluation results. Taking into account the subjective and objective evaluation results, a comprehensive odor contribution indicator is provided.

[0070] In the above-mentioned evaluation method of the contribution of automotive interior parts to the odor in the car, by using an odor screening simulation cabin to simulate the actual situation in the whole vehicle, and combining subjective and objective evaluation methods, the contribution of each interior part to the odor in the car can be quickly and accurately determined. This method does not require the analysis and calculation of the odor substances and concentrations of each interior part, thereby reducing the investment of manpower and material resources, and reducing costs and time consumption. By evaluating the contribution of each interior part to the odor in the car, a clear direction is provided for the subsequent improvement and optimization of the odor in the car. The odor screening simulation cabin is used to simulate the in-car environment to more realistically reflect the actual impact of each interior part on the odor in the car. By combining the subjective evaluation of the odor evaluator and the objective evaluation of the electronic nose, a more comprehensive and accurate odor contribution evaluation is provided. This method avoids the complex chemical analysis process, simplifies the evaluation process, and makes the evaluation process more efficient.

[0071] In an exemplary embodiment, as shown in FIG3 , before obtaining the first subjective evaluation average value of the odor intensity of each interior decoration component in the odor screening simulation cabin, the method further includes:

[0072] Step S302, obtaining a single person's subjective evaluation value and a second objective evaluation value of the odor intensity of each interior component in the odor screening simulation cabin;

[0073] Step S304: constructing a car odor intensity level model using the Weber-Hill method according to the single-person subjective evaluation value of the odor intensity and the second objective evaluation value.

[0074] Specifically, a single odor evaluator independently evaluates the odor samples in the simulation chamber and records the odor intensity. These evaluations are based on personal olfactory perception and are usually conducted according to a pre-set scoring standard, such as from "no odor" to "very strong", as a single person's subjective evaluation value.

[0075] Use objective instruments such as electronic noses to test the odor samples in the simulated cabin to obtain a second objective evaluation value. This value is obtained by the instrument based on the preset model and algorithm, reflecting the odor intensity of the interior parts.

[0076] The Weber-Fechner law is used to combine the subjective evaluation value of a single person and the second objective evaluation value to construct a car's odor intensity level model. The Weber-Fechner law is a law in psychology that describes the relationship between stimulus intensity and perceived intensity. In odor evaluation, this law can be used to convert the physical concentration of odor (such as TVOC value) into the odor intensity level perceived by humans.

[0077] By recording the intensity of odors at different dilutions and the corresponding TVOC values, a model can be built that predicts the intensity of human perception of odors at different concentrations. This model helps standardize the odor evaluation process and provides a quantifiable measure for odor intensity.

[0078] In this embodiment, through these steps, it can be ensured that the odor evaluation includes both the subjective feelings of individuals and the objective measurement of instruments, and a reliable odor intensity level model is established through scientific methods. Such an evaluation method can more accurately reflect the actual contribution of interior decoration parts to the odor in the car, and provide a scientific basis for improving and optimizing the air quality in the car.

[0079] In an exemplary embodiment, obtaining a first objective evaluation value of the odor intensity of each interior component in an odor screening simulation cabin includes:

[0080] The odor intensity rating model is used to obtain the first objective evaluation value of the odor intensity of each interior component in the odor screening simulation cabin.

[0081] Specifically, before conducting an evaluation, it is necessary to first establish an odor intensity rating model. This model is usually based on the Weber-Fechner law, which describes the relationship between stimulus intensity and perceived intensity. In odor evaluation, this model converts the physical concentration of odor (such as TVOC value) into a perceptible odor intensity rating. An electronic nose or other similar instrumentation is used to measure the odor substances of each interior component in the simulated cabin. These devices can objectively detect and analyze the types and concentrations of odor substances.

[0082] The odor substance concentration data measured by the electronic nose or other equipment is input into the odor intensity rating model. The model will calculate the objective intensity of the odor based on these data and the mathematical relationship established previously. The odor intensity value calculated by the model is the first objective evaluation value. This value represents the objective intensity of the odor of each interior component in the simulated cabin and is a quantitative and repeatable measurement result. Before the model is actually applied, it needs to be verified and calibrated to ensure the accuracy and reliability of the model. This usually involves comparing the output of the model with known odor intensity standards and possible adjustments. Record the objective evaluation values ​​obtained from the model and analyze them. These data can be used for further research or compared with subjective evaluation results to obtain a more comprehensive odor evaluation.

[0083] In this embodiment, this method can ensure the objectivity and accuracy of odor evaluation, providing a scientific basis for improving and optimizing the air quality in the car. This objective evaluation method helps automobile manufacturers identify and prioritize those interior parts that have the greatest impact on the odor in the car, thereby improving the air quality in the car and meeting consumers' requirements for health and comfort.

[0084] In an exemplary embodiment, obtaining a single person's subjective evaluation value and a second objective evaluation value of the odor intensity of each interior component in the odor screening simulation cabin includes:

[0085] Use a sampling catheter to connect the electronic nose sampling point and the sampling point of the odor screening simulation cabin, and place the olfactory identification port in the middle of the odor screening simulation cabin;

[0086] Fill the odor screening simulation cabin with nitrogen and control the input flow of nitrogen to adjust the dilution multiple of nitrogen;

[0087] The subjective evaluation values ​​of odor intensity at different dilution multiples were obtained by a single odor evaluator, and the second objective evaluation values ​​at different dilution multiples were obtained by using the olfactory cup connected to the air outlet of the electronic nose.

[0088] Specifically, a sampling catheter is used to connect the sampling port of the electronic nose to the sampling port of the odor screening simulation cabin. This connection ensures that the odor samples can be effectively collected and analyzed by the electronic nose from the simulation cabin. The olfactory port is placed in the middle of the odor screening simulation cabin to ensure that the odor samples are evenly distributed in the cabin, avoiding local concentrations that are too high or too low, thereby improving the accuracy of the assessment. Nitrogen is filled into the odor screening simulation cabin. As an inert gas, nitrogen will not react with odor substances. By controlling the input flow rate of nitrogen, the dilution multiple of nitrogen can be adjusted. The purpose of this process is to dilute the concentration of odor substances so that the odor intensity is within an evaluable range, avoiding the odor being too strong and causing the evaluator to be unable to accurately perceive it.

[0089] The subjective assessment of odor intensity is performed by a single odor evaluator. The evaluator smells the odor at different dilutions and records their own perception results. These results are usually expressed in the form of an odor intensity scale, such as from "no odor" to "strong odor", and are classified according to the dilution factor.

[0090] The olfactory cup connected to the outlet of the electronic nose is used to obtain the second objective evaluation value at different dilution multiples. The electronic nose will analyze the odor sample, measure the concentration of the odor substance, and calculate the corresponding odor intensity. This evaluation is based on the objective data of the instrument and can provide a basis for mutual verification with the subjective evaluation.

[0091] Record the subjective evaluation value of a single person and the second objective evaluation value. These data will be used for subsequent analysis and comparison to evaluate the contribution of each interior component to the odor in the car. By comparing the results of subjective and objective evaluations, you can have a more comprehensive understanding of the characteristics of the odor and provide a basis for subsequent odor improvement. Combine the obtained subjective and objective evaluation values ​​and analyze them using the previously established odor intensity grade model. This can help determine the odor contribution of each interior component under different conditions.

[0092] In this embodiment, through these steps, the scientificity and accuracy of the odor evaluation can be ensured, providing reliable data support for the improvement and optimization of the air quality in the car. This method combining subjective and objective evaluation can more comprehensively reflect the actual impact of interior decoration parts on the odor in the car.

[0093] In an exemplary embodiment, obtaining a first subjective evaluation average value of the odor intensity of each interior component in the odor screening simulation cabin includes:

[0094] Use the sampling tube to place the olfactory port in the middle of the odor screening simulation cabin, and fill the odor screening simulation cabin with nitrogen to exhaust the test gas;

[0095] Using at least one odor evaluator, a first subjective evaluation average value of the odor intensity of each interior component in the odor screening simulation cabin is obtained.

[0096] Specifically, the process of obtaining the first subjective evaluation average value of the odor intensity of each interior component in the odor screening simulation cabin involves using human sense of smell to evaluate the odor intensity and calculating the average value of the odor intensity levels given by all odor evaluators participating in the evaluation.

[0097] The olfactory port is placed in the middle of the odor screening simulation cabin using a sampling tube. This is done to ensure that the odor assessor can be exposed to the mixed sample of odors released by various interior parts in the cabin, and the central position helps to obtain the average distribution of odors in the cabin.

[0098] Fill the odor screening simulation chamber with nitrogen to exhaust the test gas. Nitrogen is an inert gas that will not react with odor substances released by interior parts. Filling with nitrogen can remove the existing odor in the simulation chamber and prepare for new odor tests.

[0099] Use at least one odor evaluator to evaluate the odor in the simulation cabin. Odor evaluators need to be professionally trained and able to perceive and describe the intensity of odors according to specific evaluation criteria. Odor evaluators sniff the odor through the olfactory port and record the intensity and characteristics of the odor. Odor evaluators will give a value based on the intensity of the odor, which is usually based on a standardized scoring system, such as a score from 0 (no odor) to 5 (extremely strong odor). If multiple odor evaluators participate in the evaluation, it is necessary to collect the odor intensities given by all evaluators and calculate the average of these values. This average represents the consensus of the odor evaluation team on the odor intensity of each interior component in the simulation cabin, and is a data that integrates the perceptions of multiple evaluators. Record the first subjective evaluation average and analyze it. This data can be used to compare with the objective evaluation value and can also be used for subsequent odor improvement work. In order to ensure the reliability of the evaluation results, multiple evaluators may need to conduct independent evaluations and calculate the final average. This helps to reduce the influence of the subjectivity of a single evaluator and improve the accuracy and consistency of the evaluation results.

[0100] In this embodiment, this method combines human olfactory perception and scientific evaluation standards to more accurately evaluate the contribution of interior decoration parts to the odor in the car, providing a scientific basis for improving and optimizing the air quality in the car. This subjective evaluation method helps capture odor characteristics that may be missed by instruments, because the human olfactory system is very sensitive to certain odors, especially those that have a greater impact on human perception.

[0101] In an exemplary embodiment, evaluating the odor contribution of each interior component according to the first subjective evaluation average value, the first objective evaluation value, and the second subjective evaluation average value of the odor intensity includes:

[0102] The objective evaluation value and the second subjective evaluation average value are subtracted from the first subjective evaluation average value to obtain the odor contribution of the interior decoration parts, and the odor contribution of each interior decoration part is ranked.

[0103] Specifically, the first subjective evaluation average value (A1) is the average value of the subjective odor intensity evaluation conducted by the odor evaluation team when all interior parts are in the odor screening simulation cabin. The first objective evaluation value (B1) is the odor intensity value obtained under the same conditions using objective instruments such as electronic noses. The second subjective evaluation average value (A11) is the average value of the subjective odor intensity evaluation of the remaining interior parts after removing specific interior assembly parts.

[0104] The odor contribution of each interior component is calculated using the formula: K=A1-B1-A11. All interior components are sorted according to the calculated odor contribution K. Interior components with higher contributions have a greater impact on the odor in the car, so odor improvement measures may need to be prioritized. The sorting results can identify the interior components that contribute the most to the odor in the car, providing a basis for subsequent material selection, design improvements, or odor control measures. The odor contribution ranking of interior components helps manufacturers determine which components require special attention and improvement to reduce unpleasant odors in the car and improve passenger comfort and satisfaction.

[0105] In this embodiment, this method combines subjective and objective evaluations to provide a comprehensive perspective to evaluate the impact of interior trim on vehicle odor. In this way, vehicle odor problems can be identified and solved more accurately, thereby improving the quality of vehicle interiors and the riding experience of passengers.

[0106] The most detailed embodiment of this application is:

[0107] (1) All interior parts are placed in the odor screening simulation cabin according to the actual layout of the vehicle. For assemblies such as carpets, ceilings, seats, etc., the parts that are not exposed in the car are covered with tin foil. The volume of the odor screening simulation cabin is adjusted to be consistent with the volume of the vehicle. The sealing temperature is set to 25°C, the humidity is set to 50%, and the sealing time is set to 16 hours. After the sealing is completed, the electronic nose sampling point and the odor simulation cabin sampling point are connected through the sampling catheter. The electronic nose fast carrier gas interface is connected to nitrogen, and the nitrogen flow rate is controlled to 10L / min. The odor evaluator conducts subjective odor intensity evaluation through the olfactory cup connected to the electronic nose outlet, adjusts the dilution factor, and records the odor intensity and corresponding TVOC value at different dilution factors. The odor level model is established through the Weber-Fechner law.

[0108] (2) Place the sampling tube connected to the olfactory port of the odor screening simulation cabin in the middle of the cabin, and discharge the gas in the cabin by filling it with nitrogen.
