In the context of progressive automation of the driving activity, an alternation of automated driving phases and manual driving phases is becoming a reality. The problem of regaining manual control of the vehicle after a period of automated control (i.e., take-over) is critical, particularly concerning visual exploration during the transition phase. A driving simulator experiment was designed to investigate the impact of the level of agentivity manipulated by different levels of motor engagement on gaze parameters during the different temporal stages of a non-critical take-over situation (i.e., overtaking collision zone). The level of motor engagement decreased according to the increase in the level of automation; eye tracking data were collected, and gaze distribution over functional areas of interest was analysed across several periods of interest. Results revealed an influence of the degree of motor engagement on the gaze parameters linked to the integration and processing of visual information for a nominal driving period (i.e., automation activated) as well as during the take-over preparation period. During the period of effective resumption of manual control, most of the ocular parameters went back to their initial values, except for the higher motor disengagement modes (i.e., lowest levels of agentivity). These automation levels seem to show a residual influence of take-overs on manual driving, particularly in the ocular exploration of areas carrying the information useful for the fine regulation of the vehicle trajectory.

在驾驶活动逐渐自动化的背景下，自动驾驶阶段和手动驾驶阶段的交替正在成为现实。经过一段时间的自动控制（即接管）后重新获得车辆的手动控制的问题至关重要，特别是在过渡阶段的视觉探索方面。驾驶模拟器实验旨在研究在非关键接管情况（即超车碰撞区）的不同时间阶段，不同运动参与水平所操纵的能动性水平对注视参数的影响。电机接合度随着自动化水平的提高而降低；收集眼动追踪数据，并分析多个感兴趣时期的感兴趣功能区域的注视分布。结果揭示了运动参与程度对与标称驾驶期间（即自动激活）以及接管准备期间视觉信息的整合和处理相关的注视参数的影响。在有效恢复手动控制期间，除了较高的运动脱离模式（即最低水平的能动性）之外，大多数眼部参数回到其初始值。这些自动化水平似乎显示出接管对手动驾驶的残余影响，特别是在对携带对车辆轨迹精细调节有用的信息的区域进行目视探索时。
