定性与定量分析跟驰行驶中汽车驾驶员情感-行为交互作用机理

Understanding the interaction between drivers’ emotions and driving behavior is essential for developing anthropomorphic autonomous vehicles and achieving intelligent human-machine interaction in connected vehicles. Previous research has focused on the impact of emotions on driving behavior, but the effects of driving behavior on driver emotion remain largely unexplored. From a new perspective of driving behavior affecting drivers’ emotion, this proposal will deeply analyze the interaction between drivers’ emotions and driving behavior during car-following from the perspective of cognition under a microscope. The study will conduct the real driving experiments and driving simulations to collect the human-vehicle-environment data, and apply the qualitative methods of think aloud、survey questionnaire、individual interview and focus group interview to collect drivers’ emotional and cognitive data. Grounded theory method will be used to investigate the mechanism of the interaction between drivers’ emotions and driving behavior. Structural Equation Model will be used to analyze the interaction effects of drivers’ emotions and behavior. Hidden Markov Model will be used to determine the transformation mechanism of driving behavior triggered by drivers’ emotions. By integrating the quantitative and qualitative results, an interaction model between emotions and behavior will be established based on drivers’ cognitive paths and sequences on processing traffic information during driving. The findings of this study can provide strong support for the development of personalized driving warning system and intelligent human-machine interaction.

研究驾驶过程中的情感特点和行为模式，正确认识驾驶情感与行为之间的影响作用，是实现拟人化无人驾驶和智能网联环境下人车和谐交互的重要基础。目前研究大多关注在驾驶情感对于行为的影响，而忽视了驾驶行为影响情感的研究。本项目拟从驾驶行为影响情感这一新视角出发，深度剖析在跟驰行驶中驾驶情感与行为在认知范畴内的微观交互作用机理，并定量分析驾驶情感与行为的影响作用效应。本研究通过模拟驾驶和实车道路实验，运用think aloud、问卷、个人深度访谈和焦点小组访谈等定性方法收集内隐驾驶员情感认知数据。使用扎根理论探究驾驶情感与行为的交互作用机理；运用结构方程模型剖析驾驶情感与行为的作用效应；采用隐马尔科夫模型推理情感演变激发的驾驶行为转移规律。在定性和定量分析的基础上，根据驾驶员认知路径和序列构建驾驶情感与行为交互作用模型。本研究阐明的作用机理和构建的交互模型，为车辆预警系统和人机交互的发展提供理论依据。
