在车辆无法安全运行的情况下，半自动驾驶汽车偶尔会要求将控制权移交给驾驶员。目前，这样的交接请求要求司机几乎是在瞬间接管控制权。我们研究了在双重任务场景中，在交接请求之前发生的听觉预警如何影响交接的成功。在一项使用驾驶模拟器的研究中，驾驶员在汽车处于自动驾驶模式时通过手机执行任务。在标准的立即移交警告之前，他们会收到重复的突发音频预警或增加的脉冲音频预警。结果表明，与没有预警的情况相比，预警会使人们在交接前更多地关注道路，并更早地脱离次要任务。这导致了更安全的移交情况。越来越多的脉冲预警显示出特别的希望，因为它们传达了紧迫性。我们的详细分析为自动化安全关键系统警报的设计和评估提供了依据。
Semi-autonomous vehicles occasionally require control to be handed over to the driver in situations where the vehicle is unable to operate safely. Currently, such handover requests require the driver to take control almost instantaneously. We investigate how auditory pre-alerts that occur well before the handover request impact the success of the handover in a dual task scenario. In a study with a driving simulator, drivers perform tasks on their phone while the car is in an autonomous mode. They receive a repeated burst audio pre-alert or an increasing pulse audio pre-alert preceding the standard warning for immediate handover. Results show that pre-alerts caused people to look more at the road before the handover occurred, and to disengage from the secondary task earlier, compared to when there was no pre-alert. This resulted in safer handover situations. Increasing pulse pre-alerts show particular promise due to their communication of urgency. Our detailed analysis informs the design and evaluation of alerts in safety-critical systems with automation.
