摘要
不良情绪是引发交通事故的因素之一。为预防由驾驶员情绪引发的交通事故,利用3层因果分解(驾驶员神经兴奋一驾驶员原始反应—车辆状态)深入分析情绪对驾驶行为的影响。设计并完成模拟驾驶试验,采集驾驶员高兴、悲伤、愤怒和恐惧4种情绪状态下的心电信号和行车数据;采用基线信号消除方法,分析驾驶员心跳间期、转向角和最大车道偏离在不同情绪下的变化值。结果表明:驾驶员在所有情绪状态下都有明显的交感神经兴奋并伴随着转向角度值增加。在高兴和愤怒情绪状态下,会产生更明显的车道偏离,驾驶员趋向更危险的驾驶行为;在悲伤和恐惧情绪状态下,产生较小范围的车道偏离,驾驶员趋向相对安全的驾驶行为。
Emotion is one of the significant factors that cause traffic accidents. In order to prevent traffic accidents caused by drivers’ emotions,a three-level causal decomposition( arousal,reaction,vehicle state)is proposed to further analyze the influences of emotions on driving behaviors. Simulated driving experiments were designed and carried out to collect data on drivers in four emotional states: happy,sad,angry and fear. By using the baseline signal elimination method,the change value of the driver’s heartbeat interval,steering angle and maximum lane deviation under different emotional sources were analyzed. The results indicate that all emotions incur significant increases in mean sympathetic arousal accompanied by significant increases in mean steering,that both the happy emotion and the anger emotion will result in a significantly larger range of lane departure,indicating more dangerous driving behaviors,and that both the sad emotion and the fear emotion will result in a smaller range of lane departure,indicating safer driving behaviors.
