重要的是要了解影响驾驶员是否愿意依赖自动驾驶系统以保持对该系统的适当信任的因素。本研究的目的是通过考虑超越一辆滑板车和自动超过一辆自行车来调查系统行为与驾驶员信任之间的关系。利用驾驶模拟器，首先研究了驾驶员在超车或超车时的峰值行驶速度、物体与测试车辆之间的峰值横向距离以及首次转向输入正时。其次，将获得的数据应用于参数设计，设计了自动驾驶系统。最后，通过改变系统参数考察了系统行为差异对驾驶员信任的影响。结果表明，司机的信任度随着这三个参数的不同而不同。此外，分析表明，自动驾驶系统应该保持较长的峰值横向距离，并比人类驾驶员更早地进行转向操作，以便分别保持主观上合适的横向距离和转向操作开始时间。此外，超车或超车的最高驾驶速度应保持与人类驾驶员的手动速度几乎相等，以保持主观上合适的驾驶速度。
It is important to learn about the factors that affect a driver's willingness to rely on an automated driving system in order to maintain appropriate trust in the system. The purpose of this study was to investigate the relationships between the system behavior and a driver's trust by considering overtaking a scooter and passing a bicycle automatically. Using a driving simulator, we first investigated the peak driving speed, the peak lateral distance between the object and the test vehicle, and the first steering input timing of human drivers while overtaking or passing. Next, the obtained data were applied to the parameters to design an automated driving system. Finally, we investigated the effects of differences in system behavior on drivers' trust by varying the system parameters. The results demonstrated that drivers' trust varied according to these three parameters. Moreover, the analysis indicated that an automated driving system should maintain longer peak lateral distances and engage in steering manoeuvres earlier than human drivers would in order to maintain a subjectively appropriate lateral distance and steering manoeuvre start time, respectively. Furthermore, the peak driving speeds for overtaking or passing should be kept almost equal to the manual speeds of human drivers to maintain subjectively appropriate driving speeds.
