【摘要】：基于中国自然驾驶工况数据,提出了紧急工况下驾驶员转向变道行为的特征规律.分析了紧急转向变道避撞、侧移和稳定阶段的驾驶员转向特征,研究了转向持续时间、方向盘转速和转角的线性关系,定义了用高斯函数拟合的转向基元来表征各阶段的转向行为.研究结果表明,转向基元表征了驾驶员转向行为的一般特征,单个转向基元的方向盘最高转速和转角变化线性相关,持续时间恒定,符合人体行为学中趋向行为(reaching behavior)的特征规律.驾驶员的紧急转向变道行为是由多个转向基元组合而成,每个转向基元都是一个开环模型,可通过方向盘最高转速预判驾驶员的转向行为.
[Abstract]:Based on the data of natural driving conditions in China, the characteristics of steering behavior of drivers under emergency conditions are proposed. In this paper, the steering characteristics of drivers in the phase of collision avoidance, lateral shift and stability of emergency steering are analyzed, and the linear relationship among steering duration, steering speed and rotation angle is studied. The steering elements fitted by Gao Si's function are defined to represent the steering behavior of each stage. The results show that the steering unit represents the general characteristics of the steering behavior of the driver. The steering speed of a single steering unit is linearly correlated with the change of the rotation angle, and the duration of the steering unit is constant. It is in accordance with the characteristic law of trend behavior (reaching behavior) in human behavior. The emergency steering behavior of the driver is composed of several steering elements, each of which is an open-loop model, which can predict the steering behavior of the driver through the maximum speed of the steering wheel.
