摘　　要：随着车辆保有量的与日俱增,道路通行效率问题日益严重,特别是紧急救援车辆的救援效率问题。针对弯道路段因无法判断能否安全超越前方慢速行驶车辆,而导致后方紧急救援车辆低速跟随行驶的工况,提出了一种基于车路通信的弯道超车安全预测方法。运用车-路互联技术获取准确的路况信息,建立四自由度车辆动力学模型计算安全车速,并设计了车辆弯道超车行驶的安全碰撞预测算法,最后通过典型弯道路况进行仿真验证。仿真结果表明,该方法能够为驾驶员提供准确的预测信息,有效增强车辆超车行驶的安全性(与对向、同向车辆无碰撞)和稳定性(本车无侧滑、侧翻),提高道路通行效率。The problem of road traffic efficiency is becoming increasingly serious,especially the rescue efficiency of emergency rescue vehicles with the increasing number of vehicles.when the rear emergency rescue vehicles follow at low speed due to the inability to judge whether they can safely overtake the slow moving vehicles in front,a safety prediction method was proposed to predict the safety of overtaking in curve sections based on vehicle road communication.The specific research contents included:First,the vehicle road interconnection technology was used to obtain accurate road condition information;Then a four degree of freedom vehicle dynamics model was established to calculate the safe speed;Finally,the safety collision prediction algorithm for vehicles overtaking in curves was designed,and simulation verification was conducted through typical curve road conditions.The simulation results show that the method can provide accurate prediction information for drivers,effectively enhance the safety(no collision with opposite and same direction vehicles)and stability(no side slip and rollover of the vehicle)of overtaking,and improve the road traffic efficiency.
