Abstract: In order to make the new model meet the odor of the vehicle at the same time, further improve the odor quality of the vehicle, and ultimately effectively improve the user's evaluation of the odor in the vehicle. In this paper, vehicles that have met the odor level of the vehicle are decomposed according to the component assembly, and according to the contribution of each component to the odor impact, the key components that can be improved are identified. Through further production design, process improvement and effective control, the ultimate goal of improving the odor level of the vehicle is achieved by improving the odor quality of the assembly parts. The test results show that, when the lifting assembly parts are used to load the vehicle, the odor level of the vehicle reaches level 6.0+, meet the requirements of a vehicle enterprise standard. This study has important practical and guiding significance for the design and improvement of hidden B-pillar battery electric vehicle odor.
