基于流程特征的用户安全驾驶移交体验

Driver Handover Safety Experience Based on Process Characteristics

目的探索流程特征在智能汽车驾驶移交任务中的应用,提升用户驾驶移交操作的安全体验。方法基于绿野仙踪方法,选取五十一位驾驶用户进行实验,以用户安全感知理论为基础,通过定性和定量方法,评价基于不同流程的移交激活、速度调节、确认操作等动作对用户驾驶移交体验的影响,对关键安全感知因素进行提取分析,提出基于流程特征的移交操作设计策略。结论不同流程特征下的移交操作设计对用户的安全感知有影响,在高紧急情境中,用户对速度调节有较高的操作负担,因此在移交操作设计中需要降低它给用户带来的影响;在低紧急情境中,用户对确认操作作为操作结束点的普遍安全感知较强,因此未来在移交体验的结束节点应让用户充分理解移交过程。验证流程特征对用户体验带来的影响,为相关从业人员提供了新的观察视角。

The work aims to explore the application of process characteristics in the handover task of intelligent vehicle and improve the safety experience of user driving handover operation. With the wizard of OZ method, 51 users were selected for the experiment. Based on the user safety perception theory, qualitative and quantitative methods were used to evaluate the influence of actions such as transfer activation, speed selection and confirmation based on different processes on the user’s handover experience. The key safety perception factors were extracted and analyzed, and the handover operation design strategy based on process characteristics was proposed. Handover operation under different process characteristics has influence on user’s safety perception. In the high emergency situation, the user has a high operational burden on speed selection, so it is necessary to reduce the impact on the user in the design of handover operation. In the low emergency situation, the user has a strong general safety perception of confirming action at the end point of the process. Therefore, the end of handover experience in the future should allow the user to fully understand the handover process. The impact of process characteristics on user experience is verified, which provides a new perspective for relevant practitioners.
