基于自然驾驶试验的山区公路纵坡路段驾驶负荷分析
Analysis of driver workload on slopes of mountain highways based on naturally driving tests
摘要
Abstract
To obtain the driver workload during travelling on slopes and the corresponding influencing factors,the field driving tests on mountain roads with complex alignment with the drivers' natural behaviors were conducted,and the operating parameters of the cars such as the vehicle running speed,the track,the acceleration,and the electrocardiograph (ECG) signal of the drivers were collected.The relationship among the vertical alignment parameters,the acceleration/deceleration rate and the heart rate increase HRI of the drivers was analyzed.The results show that there exists an interaction among the slope parameters,the acceleration rate and HRI.A weak positive correlation between the slope length and HRI exists.There is a strong correlation between HRI and the gradient,and the correlation of the downhill is stronger than that of the uphill.The longer the slope length,the higher HRI caused by an increase in the gradient.A positive correlation between HRI and the acceleration/deceleration exists.With the increase of the slope gradient,HRI is more sensitive to the changes in the acceleration/deceleration.The correlation between HRI and the deceleration of the downhills is more significant than that between HRI and the deceleration of the uphills.关键词
