结合遗传算法等工程方法和交互式评价等设计方法，提出一种整合了工程方法和造型方法的汽车造型优化设计方法。方法整体以进化思想为指导，首先将汽车造型设计问题映射到数学模型上，利用遗传算法生成新设计方案，并以多目标设计空间来约束生成的设计方案，再以目标车型的造型意象为标杆，采用交互式评价方式评价输出的设计方案，并将评价结果作为适应度代入遗传算法中继续迭代直至设计方案符合设计的迭代终止条件，最终形成一个综合解决多方问题的汽车造型多目标优化设计方法。以某小型两厢车车型为例，初步证明了该方法的合理性和可行性。该方法可以推广到汽车造型多目标优化概念辅助生成和汽车造型评价等领域。

This paper combined the engineering methods like genetic algorithm as well as the de-sign methods like interactive evaluation,a set of optimization design methods for automobile styling was proposed by integrating engineering and design methods.The method was instructed by evolution theory,mapping automobile styling problems to mathematical model and using genetic algorithm to generate new design proposals.A multi-obj ective design space was quantized to restrain the generated design proposals.With the output of the proposal that correspond with the multi-obj ective design space,the interactive evaluation was utilized to evaluate the generated design proposal.Then the evalu-ation results as fitness were plugged into genetic algorithm until corresponding the design proposal. Finally,an optimization design method of vehicle styling was formed,which can solve problems of dif-ferent aspects in anintergrated perspective.The rationality and feasibility of this method was proven with an example of a small hatchback.This method can be extended to the field of multi-obj ective op-timization concept generation and the evaluation of automobile styling and so on.
