Mechanism of Run-Off-Road on Horizontal Curves Caused by Collision Avoidance of Vehicles

摘要

摘要: 通过仿真获得了平曲线上避让过程中车辆的动力学响应.根据轮胎侧向力的变化,分析曲线内外侧车辆避让轨迹的曲率变化.车辆驶出路面事故的机理是避让时产生了过大的附加曲率.驾驶者在避让之前应适当减速,以减小附加曲率导致的附加离心力;与对向来车交会之后应平缓地驶回到原来行车线.

Abstract: Dynamic responds of a vehicle during collision avoidance were obtained through simulation.The curvatures of the traveling path for collision avoidance of two vehicles running in opposite directions were analyzed according to the lateral forces acting on tires.An excessive additional curvature caused by collision avoidance causes a vehicle to run off road on a horizontal curve.From the safety point of view,a vehicle should decrease speed as early as possible before collision avoidance to avoid excessive additional curvature and centrifugal forces,and go back to its normal path gradually.
