摘要:
为得到驾驶人在纵坡路段上行车时的驾驶负荷及其影响因素,在山区复杂线形公路上开展了自然驾驶试验,采集了真实驾驶习惯条件下的汽车行驶速度、轨迹、加速度等运行参数和驾驶人心电信号,分析了公路纵面线形参数、汽车加(减)速度与驾驶人心率增长率HRI之间的关系.结果表明,纵坡参数、加速度与HRI三者之间相互影响.坡长与HRI之间存在较弱的正相关性;坡度与HRI之间存在较强的相关性,其中下坡路段的相关性强于上坡路段,并且坡长越长,坡度增加导致HRI的增长越明显;HRI与加(减)速度正相关,坡度越大,HRI对加(减)速度的变化越敏感,且下坡路段减速度与HRI的相关性较上坡路段加速度与HRI的相关性更显著.
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.
