奇瑞?汽车工程研究院 奇瑞?汽车工程研究院 奇瑞汽车产品开发中的性能设计 曾 皓 2008年9月 市场推介活动 Chinese auto makers have achieved impressive growth (market share, volume,self innovation) in last ten years. Chinese auto makers are very ambitious to become globally competitive players and expand their products into Western markets. The current engineering structure and operation may not be ready to support these goals, when compared to globally successful Asian automakers such as Toyota, Honda and Hyundai. 汽车开发中的主要性能 Millions 1960 - 2005 中国汽车工业的发展现状 汽车开发中的主要性能 现在的 OEM PD作法 (A) Purchased existing vehicle specifications from other OEM’s for models that had already been engineered to meet China domestic market requirements. Limited requirement to engineer new components and systems. Purchased existing powertrain modules from other OEM’s. Learned to launch existing models into series production while growing up the PD organization. Step 1. Fully relying on outside design and engineering companies to develop vehicles and key components. Step 2 Body structure, Interior/exterior, Electronics Step 3. Key components, such as Powertrain. (Participating incuture joint development with outside design company to develop exclusive intellectual property for a full line of engines). Step 4. Chassis Design, Vehicle engineering development Hired additional Chinese engineers from existing OEM’s with some automotive engineering experience. Jointly building up the auto parts suppliers Developed initial capabilities for building prototype vehicles and performing Engineering development. Still limited experience and resources to develop all specifications for new models 现在的 OEM PD作法 (B) 汽车开发中的主要性能 上述开发流程对制造，协调要求比较高。孕育了现代化的中国制造业。 车身，Chassis盘，内外饰，电器 整车 协调，调试 下一步需解决国际公认的正向开发。功能模块（Attributes）的研发。 安全性，NVH，可靠性，操纵性，。。。。。 汽车产品开发流程 整车 系统 子系统 零部件 产品/流程 设计 目标分解 设计验证 优化 设计/ 生产 确认 下线/ 批量生产 确认 更新 公司 经验库 外型确定 立项 定义 设计 验证/下线 42 33 16 0 -3 以PAT（产品属性小组）Leader为核心 围绕性能目标进行产品开发 Vehicle Eng
