Abstract: In recent years, due to the problem of vehicle production consistency, there are defects in its product quality and affect its sales from time to time. The problem that enterprises fail to implement the China Compulsory Certification(3C) certification consistency standard in vehicle production has also become the focus of social attention. Therefore, commercial vehicle enterprises need to build a production consistency control plan to realize the consistency management of products, so as to meet the quality certification of products. Based on the analysis of 3C certification mode of commercial vehicles, this paper compiles the production consistency control plan for commercial vehicle models, takes a commercial vehicle as an example, controls the consistency of its key parts and production process, and formulates the control requirements of vehicle production consistency test for cop test. Finally, the consistency control plan of 3C certification is comprehensively applied in the product design, production and after-sales of commercial vehicles. Through this application, the products after mass production meet the requirements of product consistency and meet the national mandatory product certification standards. This has played a good role in improving product quality and protecting consumers' rights and interests.
