紧急路况下智能网联车辆队列控制策略设计及仿真分析

Design and Simulation Analysis of Control Strategy for Intelligent Connected Vehicles Queue under Emergency Road Conditions

智能网联车辆队列能够有效改善燃油经济性、提高行车安全性,但在实际中不可避免会遇到其他车辆干扰需要紧急制动的路况。对紧急路况下智能网联车辆队列控制策略进行研究,确保车辆队列的行车安全性与稳定性。对紧急制动、他车插入并长时间停留、他车插入并快速驶离3种紧急路况下的控制策略进行设计,并在PreScan平台下开展3种控制策略的仿真试验。结果表明,所设计的3种紧急路况下的控制策略能够确保智能网联车辆队列的安全、稳定行驶。

The intelligent connected vehicle queue can effectively improve fuel economy and driving safety,but in practice,it is inevitable to encounter other vehicles interference and need emergency braking.The queue control strategy for intelligent connected vehicles under emergency road conditions was studied to ensure the driving safety and stability of the vehicle queue.The control strategies under three kinds of emergency road conditions,namely,emergency braking,other vehicles stopping for a long time after insertion and other vehicles driving away quickly,after insertion,were designed and the simulation tests of the three control strategies were carried out on the PreScan platform.The results show that the three control strategies designed under emergency road conditions can ensure the safe and stable driving of the intelligent connected vehicle queue.
