| 目的 更好地发挥车外人机交互界面(eHMI)的潜在优势，研究车外人机交互过程中的信任影响机制。方法 首先基于自动化信任理论，提出感知可靠性、感知透明度、感知熟悉度、感知车辆性能、感知品牌信誉和感知主观倾向等6个车外人机交互信任影响因素，然后使用结构方程模型的方法对305名被调查者进行数据分析，由此建立车外人机交互信任影响因素的理论模型。结果 行人通过对eHMI信号感知而形成的信任能够影响对自动驾驶汽车的信任，行人对eHMI的信任一定程度上转移成为行人对车辆的信任，eHMI的辅助作用得到体现。强调了eHMI设计中感知可靠性的重要性，这能够被熟悉度、透明度和品牌信誉所影响。同时，行人的主观倾向和对车辆性能的感知也是影响信任水平的重要因素。结论 研究结果为车外人机交互信任对于自动驾驶汽车在未来道路上使用的重要性提供了证据，同时也为eHMI的设计提供了参考和建议。 |

| Abstract: |
| The work aims to study the trust influencing mechanism in external human-computer interaction (eHMI) to better utilize the potential advantages of eHMI. Firstly, based on the theory of automated trust, six factors influencing trust in eHMI, namely perceived reliability, perceived transparency, perceived familiarity, perceived vehicle performance, perceived brand reputation, and perceived subjective tendency, were proposed, and then the data of 305 respondents were analyzed using the method of structural equation modeling to establish a theoretical model of the factors influencing trust in eHMI. The results showed that the trust formed by pedestrians through the perception of eHMI signals could influence the trust in autonomous vehicles, the trust of pedestrians in eHMI was transferred into the trust of pedestrians in the vehicle to a certain extent, and the auxiliary role of eHMI was reflected. The importance of perceived reliability in eHMI design was emphasized, which could be influenced by familiarity, transparency and brand reputation. Also, pedestrians' subjective tendencies and perceptions of vehicle performance were important factors influencing the level of trust. In conclusion, the findings provide evidence for the importance of trust in eHMI for the future use of autonomous vehicles on the road, as well as providing references and recommendations for eHMI design. |
