本文利用动态心电分析仪、Freecod数据采集系统及动态GPS,在交通运输部试验场对紧急状况下驾驶员心率变化与车距障碍物距离以及行驶车速间的关系进行了试验研究。试验结果表明,遇到障碍物时,心率变化大体呈波浪式,上下起伏状;在傍晚,驾驶员心率变化要比中午明显。在数据分析基础上,建立驾驶员心率与车距障碍物以及心率与行车速度的回归模型,并对模型进行验证。试验结果有助于进一步明确突发事件下驾驶员的心率变化规律。
In this paper, dynamic electrocardiogram analyzer, Freecod data acquisition system and dynamic GPS were used to test the relationship between driver’s heart rate change and the distance of obstacle to vehicle and the traveling speed under the condition of emergency. The experimental results show that when encountering obstacles, the heart rate changes roughly in a wavy pattern, fluctuating in the up and down direction. In the evening, the driver’s heart rate changes more obviously than at noon. Based on the data analysis, a regression model of driver’s heart rate, obstacle of vehicle distance and heart rate and driving speed is established, and the model is verified. The test results help to further clarify the driver’s heart rate changes under emergencies.
