This study investigated the impact of driving styles of drivers and automated vehicles (AVs) on drivers' perception of automated driving maneuvers and quantified the relationships among drivers' perception of AV maneuvers, driver trust, and acceptance of AVs.
Previous studies on automated driving styles focused on the impact of AV's global driving style on driver's attitude and driving performance. However, research on drivers' perception of automated driving maneuvers at the specific driving style level is still lacking.
Sixteen aggressive drivers and sixteen defensive drivers were recruited to experience twelve driving scenarios in either an aggressive AV or a defensive AV on the driving simulator. Their perception of AV maneuvers, trust, and acceptance was measured via questionnaires, and driving performance was collected via the driving simulator.
Results revealed that drivers' trust and acceptance of AVs would decrease significantly if they perceived AVs to have a higher speed, larger deceleration, smaller deceleration, or shorter stopping distance than expected. Moreover, defensive drivers perceived significantly greater inappropriateness of these maneuvers from aggressive AVs than defensive AVs, whereas aggressive drivers didn't differ significantly in their perceived inappropriateness of these maneuvers with different driving styles.
The driving styles of automated vehicles and drivers influenced drivers' perception of automated driving maneuvers, which influence their trust and acceptance of AVs.
This study suggested that the design of AVs should consider drivers' perceptions of automated driving maneuvers to avoid undermining drivers' trust and acceptance of AVs.
本研究探讨了驾驶员和自动驾驶汽车（AV）的驾驶风格对驾驶员对自动驾驶操作感知的影响，并量化了驾驶员对 AV 操作的感知、驾驶员信任和对 AV 的接受程度之间的关系。
以前关于自动驾驶风格的研究主要集中在 AV 的全局驾驶风格对驾驶员态度和驾驶性能的影响上。然而，关于驾驶员在特定驾驶风格层面上对自动驾驶操作感知的研究仍相对缺乏。
招募了 16 名激进型驾驶员和 16 名防御型驾驶员，在驾驶模拟器中体验 12 种驾驶场景，分别是激进型 AV 或防御型 AV。通过问卷调查测量他们对 AV 操作的感知、信任和接受程度，并通过驾驶模拟器收集驾驶性能数据。
结果表明，如果驾驶员感知到 AV 的速度、减速度、减速度或停车距离高于预期，他们对 AV 的信任和接受程度会显著降低。此外，防御型驾驶员认为激进型 AV 的这些操作明显不适当，而防御型 AV 则不然，而激进型驾驶员对不同驾驶风格的这些操作的不适当感知没有显著差异。
自动驾驶汽车和驾驶员的驾驶风格影响了驾驶员对自动驾驶操作的感知，从而影响了他们对 AV 的信任和接受程度。
本研究表明，AV 的设计应考虑驾驶员对自动驾驶操作的感知，以避免削弱驾驶员对 AV 的信任和接受。
