Modeling of Driver Steering Behavior in Lateral Wind toward Driver Assistance System
Yoshinori Kurata,Norimasa Kamiji,Takahiro Wada,Shun’ichi Doi 한국자동차공학회 2008 한국자동차공학회 Symposium Vol.2008 No.9
Disturbances decrease vehicle stability and increase driver’s mental and physical workload. Especially, lateral wind increases driver’s workload greatly, because driver cannot expect it. Various driver assistance systems by steering assist have been developed to improve vehicle stability in such disturbance. Gap between vehicle motion and driver’s motion recognition characteristics, however, often leads to uncomfortable feeling in driver assistance system with steering assist. Thus, this study aims to develop more comfortable driver assistance system in lateral wind disturbance by studying relationship between driver’s motion recognition characteristics and driving behavior against disturbance. First, the driver’s posture change, the head movement and the corrective steering behavior were measured under various lateral wind conditions utilizing a driving simulator with one dof motion in lateral direction. As the results, strong correlation was found between driver’s head lateral jerk by lateral disturbance and angular acceleration of steering wheel. Then, we build a driver’s steering model against lateral disturbance based on the experimental results. Finally, validity of the proposed model is shown by comparing the steering angle of experimental results and that of simulation results.
