Method for determining key odor substances and high-risk odor parts in vehicle

Abstract

The invention relates to a method for determining key odor substances and high-risk odor parts in a vehicle. The method comprises the following steps: S1, detecting whole vehicle odor substances; S2,determining an odor substance smelling threshold; S3, calculating a threshold dilution factor and determining key odor substances of the vehicle; S4, analyzing odor substances of parts based on the detection method the same as that in the S1, determining a threshold dilution factor of the odor substances based on the S2 and S3; S5, analyzing similarity between the odor of parts and the odor of thevehicle; and S6, determining a high-risk odor part according to a similarity result sequence. The method has the following beneficial effects: the threshold dilution factor serves as the index for screening the key odor substances of the whole vehicle; the key odor substances of the whole vehicle can be determined only by testing concentrations and odor thresholds of different substances; the result accuracy is high; and with consideration of differences of the threshold dilution factors of different odor substances in the whole vehicle and parts, the similarity is calculated to determine a high-risk odor part, so that the rectification work is performed in a targeted and directional manner.

Description

technical field [0001] The invention relates to the technical field of automobiles, and the method can be used to determine key odor substances and high-odor high-risk components in the vehicle. Background technique [0002] At present, the usual practice of my country's auto industry to rectify vehicles with odor problems is: the odor evaluator checks all the interior parts of the vehicle one by one through subjective evaluation, finds the parts with poor odor performance and asks the supplier Make corrections. This method mainly has the following problems: first, relying entirely on the subjective evaluation of personnel to lock high-risk components of odor, which is greatly affected by the personal experience and subjective wishes of the evaluators, resulting in inaccurate results; second, for all parts with poor odor performance The components are all rectified, resulting in a lack of purpose in rectification, long rectification cycle and high cost.
