Analysis of Driver Emergency Steering Lane Changing Behavior Model Based on Naturalistic Driving Data

摘要:

提出了一种以驾驶员转向目标瞄点为核心的、面向操纵层的驾驶员紧急转向变道的模型建立方法.基于驾驶员紧急变道的阶段特征，提出了驾驶员紧急变道侧向运动轨迹的规划方法，并结合远近目标点理论分析方法，分阶段建立了驾驶员转向变道工况的驾驶员转向模型.对紧急转向变道中避撞、侧移和稳定阶段的增益因子的分布特征进行了研究，模型能够真实地预测自然驾驶中的紧急转向变道行为.

Abstract:

A method for establishing the lane changing steering model was presented, which was based on the steering target aiming point of the driver and was oriented to the steering maneuver layer. Based on the characteristics of the emergency lane changing, a lateral trajectory model was established. Combined with the theory of far and near aimed point, a driver steering model of lane changing was established and the distribution characteristics of gain factors were studied. The research results show that the steering model performs well when explaining realistic emergency steering behavior.
