Abstract: As commercial vehicle transmissions evolve from mechanical products toward newenergy and intelligent ones, effective R&D process management and new product quality improvement stand out as key tasks for transmission enterprises during transformation. Targeting prominent problems such as frequent defects in R&D trial production and high after-sales failure rates in new product development, this paper adopts quality gate management theory, integrates whole-process quality management and maturity management concepts, and constructs a standardized quality gate management system suitable for Fast Company from the perspectives of quality gate classification, review procedures, node planning and responsibility allocation. After implementation, this system strengthens risk interception capacity at each link, cuts after-sales failure rates, shifts quality management from passive troubleshooting to active prevention, and offers valuable references for peer enterprises in the industry to improve new product development quality.

Key words: new product development; quality gate; whole-process quality management; maturity management

摘要： 随着商用车变速器从机械式向新能源、智能化产品转变，如何有效地管理研发过程， 提高新产品开发质量，成为变速器企业发展转型的关键。针对新品研发试制问题多发、售后 故障率偏高等痛点，文章结合质量门管理理论，融合全流程质量管理与成熟度管理思想，从 质量门分级、评审流程、节点规划、职责分工等方面，设计了一套适用于法士特公司的标准 化质量门管理体系。该体系实施后，提升了各环节风险拦截能力，降低了售后故障率，推动 质量管理从被动救火向主动预防转变，为行业同类企业提升新品开发质量提供了有益借鉴。
