摘要: 对换道安全性进行研究,分析换道事故发生的主要原因。选取典型的换道场景,针对事故原因,进一步进行车辆运动学分析,建立出最小安全距离模型。综合考虑相对速度、相对纵向距离和评价指标TTC,提出符合实际的换道预警规则。运用Prescan和MATLAB/Simulink联合仿真,建立虚拟场景,进行验证。结果表明:提出的预警规则符合实际,具有实用价值和市场价值。

Abstract: The main cause of lane change accident was analyzed during the study of the security of lane change. In the typical lane change scenario, a minimum safe distance (MSS) model was established on the basis of the main cause of accident and the vehicle kinematical analysis. With the comprehensive consideration of the relative speed, the relative longitudinal distance and the evaluation index TTC (Time to collision), the realistic lane change warning rule was proposed. A virtual lane changing scenario was developed by the united simulation of MATLAB/Simulink and Prescan to verify the warning rule. The results show that the proposed warning rule accords with reality, and has practical value and market value.
