车路协同下的基于S函数的交叉口平滑车速引导方法

Smooth Speed Guidance Method of Intersection Based on S Function Under Vehicle Infrastructure Cooperative Systems

针对现有车速引导模型在通过交叉路口时,没有考虑到驾驶员需要频繁制动或车辆速度突变带来影响的情况,本文基于车路协同环境研究考虑基于S函数的交叉口平滑车速引导算法,根据车辆与路侧设施之间的通信,搭建相关算法模型并进行分析,与不采用车速引导模型相比,采用基于S函数的交叉口平滑车速引导算法模型可以降低通过交叉路口时间,提高通行效率,同时使建议速度变化平滑,提高驾驶平稳性。

In view of the fact that the existing speed guidance model does not consider the impact of frequent braking by drivers or sudden change of vehicle speed when passing through intersections,this paper studies the intersection smooth speed guidance algorithm based on S function based on the vehicle road coordination environment.According to the communication between vehicles and roadside facilities,relevant algorithm models are built and analyzed.Compared with not using the speed guidance model,using the intersection smoothing speed guidance algorithm model based on S function can reduce the time of passing through the intersection,improve the traffic efficiency,smooth the change of the recommended speed and improve the driving stability.
