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

Abstract:

The general characteristics of driver emergency steering lane change behaviors based on the China naturalistic driving data were proposed in this paper. The emergency steering characteristic was analyzed respectively in collision avoidance, lateral movement and steering stabilization phases, focusing on the steering duration time, the relationship between steering wheel rate and steering wheel deflection. The steering behaviors in three phases were described by using the steering primitive fitting by Gaussian function. The research results show that the steering primitive represents the general characteristics of driver steering behaviors. A linear relationship was found between the maximum steering wheel rate and the steering wheel deflection, and the steering time for a single steering primitive is constant. The driver emergency steering behaviors follow the characteristics of the reaching behavior. The driving emergency steering lane change is composed of steering primitives, while the single steering primitive is an opencontrol model, which indicates that the steering angle is predetermined using the maximum steering wheel rate.
