ABSTRACT

Warning systems play a crucial role in the takeover of conditional automated driving. However, the widely used single-stage warning systems in takeover had inevitable and critical issues in situation awareness (SA), driving stress, and takeover performance. As such, two-stage warning systems might be an optimal solution to alleviate these problems. On this basis, this study investigated the effect of warning types (single-stage vs two-stage warning systems) and non-driving related tasks (NDRTs) (playing Tetris game vs monitoring automated systems) on takeover. A total of 32 participants were recruited to join our driving-simulated study. These participants responded to different types of takeover warning systems upon receipt while engaging in NDRTs. Simultaneously, the SA, physiology stress, takeover performance, and acceptance data of the participants were recorded. Results showed that the drivers exhibited higher SA, lower physiology stress, better takeover performance, and higher acceptance ratings in the two-stage warning systems than in the single-stage warning systems. In conclusion, two-stage warning systems are promising in improving takeover safety based on connected vehicle technologies in the future. These findings can provide some guidelines for designers and engineers when applying the warning systems in automated driving.

有条件的自动驾驶中的逐步接管:两阶段预警系统对情况感知,驾驶压力,接管性能和验收的影响

摘要

预警系统在有条件自动驾驶的接管中起着至关重要的作用。但是,在接管中广泛使用的单阶段警告系统在态势感知(SA),驱动压力和接管性能方面具有不可避免和严重的问题。因此,两阶段预警系统可能是减轻这些问题的最佳解决方案。在此基础上,本研究调查了警告类型(单阶段两阶段警告系统)和非驾驶相关任务(NDRT)(玩俄罗斯方块游戏监控自动化系统)。总共招募了32名参与者参加我们的驾驶模拟研究。这些参与者在参与NDRT时,对收到的不同类型的接管警告系统做出了回应。同时,记录参与者的SA,生理压力,接管表现和接受数据。结果表明,与单阶段警告系统相比,两阶段警告系统中的驾驶员表现出更高的SA,更低的生理压力,更好的接管性能以及更高的接受等级。总之,两阶段预警系统有望在未来基于互联车辆技术提高接管安全性。这些发现可为将警告系统应用于自动驾驶的设计人员和工程师提供一些指导。
