目的 从汽车的类型分析出发， 对汽车造型设计问题进行定性、 定量研究， 探讨语义驱动的汽车造型设计方法。方法 构建汽车类型的原型范畴， 通过分析、 归纳、 推论等方式， 将类型成员与原型相似性度、 类型成员贡献度、 原型权重系数等概念进行形式化表征。结果 以SUV车型为例， 获得14组侧面轮廓造型的关系拟合模型， 运用11组SUV车型核心差异性语义词汇驱动汽车侧面轮廓造型生成设计。结论 基于汽车类型的分析， 其核心在于对原型范畴的运用， 以一种更加贴近设计师认知规律和思维模式的方式， 为汽车造型设计提供更加客观、 合理、 灵活的指导。

Taking vehicle type analysis as a startpoint， it studies the car styling with both qualitative and quantitative research approach to probe semantic-driven design method. By constructing the vehicle type model of prototype category， by means of analysis， induction，deduction， the relationship between type members and prototype similarity degree， type members contribution， weight coefficients of the prototype category can be formalized. Taking SUV as an example， 14 groups of contour fitting model are obtained， and 11 groups of core differential semantic vocabulary of SUV are used to generate SUV contour. Using prototype category to analyze vehicle type provides more objective， reasonable and flexible guide to car styling， which is a way closer to the cognitive rules and thinking model to car designer.
