概括
司机分心行为由欧元NCAP定义的自然发生. 眼神跟踪 (眼神) 比头部跟踪 (猫头眼神) 更频繁,突出了对先进驾驶员状态监控 (DSM) 系统的需求.
科学领域:
- 道路安全研究 道路安全研究
- 人与计算机的互动.
- 汽车工程 汽车工程
背景情况:
- 欧元国家安全计划2023年引入乘客状态监控 (OSM) 将推动采用驾驶员状态监控 (DSM).
- 欧元NCAP要求DSM系统采用特定的分心行为,以达到最大的安全等级.
- 这些分心行为和相关的驾驶员警报/干预在现实世界驾驶中的流行程度仍然未得到量化.
研究的目的:
- 为了检查在自然驾驶过程中欧元NCAP定义的驾驶员分心行为的普遍性.
- 分析司机响应这些分心事件时的警报和干预频率.
主要方法:
- 在两周内,为20名医疗保健工作者使用了一辆装有汽车级DSM的仪器车辆.
- 在日常通勤期间收集了168.8小时的连续驾驶员头部,眼睛和目光跟踪数据.
主要成果:
- 单个,长时间的分心事件是最常见的 (.89事件/小时).
- 的目光 (目光跟踪) 比猫头的目光 (头部跟踪) 更频繁.
- 视觉时间共享事件发生的速度为0.21事件/小时,警报率受视区域值的影响.
结论:
- 欧元NCAP定义的驾驶员分心现象在驾驶过程中自然表现出来.
- 眼的高频率表明,仅依靠头部跟踪的不太复杂的DSM系统将错过重要的分心事件.
- 结果告知OEM,DSM制造商和监管机构预期的警报率,影响安全性,用户体验和DSM接受度.

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
