摘要:

已有的研究表明,要使LKA系统能自适应于不同驾驶员的前提是,驾驶员喜好的LKA介入时机特性与其自身的自然驾驶特性相符合,但现实情况如何目前尚无定论。为此,本文中通过主客观评价试验获取驾驶员喜好的LKA介入时机客观指标;并采集驾驶员的自然驾驶数据,提取驾驶员转向回正点,对转向回正点进行特性量化并提取相应的指标。通过对比驾驶员喜好的LKA介入时机特性指标及其自然驾驶时的转向回正点指标发现,12.5%的驾驶员喜好的LKA介入时机特性与其自然驾驶特性存在显著差异。

Abstract:

Some researches reveal that the prerequisite for LKA system can be adapted to different drivers is the consistency of driver’s favorable LKA intervention timing characteristic with his own naturalistic driving characteristic, but the real?world situation about this is still unknown at present. In view of this, a subjective / objective evaluation test is conducted in this paper to obtain the objective indicators of driver’s favorable LKA intervention timing, and the naturalistic driving data of drivers are collected and the steering return points of drivers are chosen. Then the characteristics of steering return points are quantified with the corresponding indicators extracted. Finally, the indicators of driver’s favorable LKA intervention timing characteristic and his steering return point indicators during naturalistic driving are compared and the results show that for 12.5% of drivers, the favorable LKA intervention timing characteristic is significantly different from his naturalistic driving characteristic.
