智能汽车内外饰造型意象耦合度评价方法研究

Research on evaluation method of coupling degree of interior and exterior styling images of smart vehicle

为帮助设计人员在智能汽车造型设计早期更好地控制内外饰传达的整体意象,提出一种基于眼动实验,结合感性工学理论的智能汽车内外饰造型意象耦合度评价方法。以耦合理论为核心,通过调研获取感性意象词汇集和内外饰并存图库,引入观察距离作为调剂因子统一内外饰意象评价,运用语义差分法构建内外饰总体意象空间并获取意象过渡线;运用眼动实验获取车内外关键设计要素及客观认知权重,经专家评审修正后计算其综合权重并与意象评分结合,探索基于意象认知耦合的智能汽车内外饰造型耦合度评价方法。该方法以3款智能汽车为评价对象,将评价结果与语义差分所得评分进行对比验证,结果表明该方法准确性良好,可以指导后续智能汽车内外饰造型耦合设计。

To enhance designers’control over the overall image conveyed by interior and exterior decoration in the early stage of intelligent vehicle modeling design,an evaluation method for assessing the coupling degree of interior and exterior decoration modeling was proposed,based on eye movement experiments and Kansei engineering theory.By employing a coupling theory approach,investigations were conducted to obtain perceptual image vocabularies and co-occurrence galleries for both interior and exterior decoration.Observation distance was introduced as an adjustment factor to standardize the image evaluation of interior and exterior decoration.The semantic differential method was employed to construct an overall image space for interior and exterior decoration,enabling us to derive an image transition line.Eye movement experiments were conducted to identify key design elements and their objective cognitive weights for both car interiors and exteriors.Following expert review and correction,comprehensive weights were calculated,which were then combined with image scores.This allowed us to explore an evaluation method based on cognitive coupling of smart car interiors and exteriors.The proposed model was applied to evaluate three smart cars,with results compared to scores obtained through semantic differential analysis.Numerical findings demonstrated that our proposed method could achieve high accuracy while effectively guiding subsequent coupling designs of smart car interiors and exteriors.
