摘　　要：文章旨在探索一种新的智能网联车技术,可以有效地解决传统车辆汇入匝道冲突区域时减速甚至停车所带来的延误问题,并且可以在车路协同环境下,通过STM32等硬件实现两阶段的优化模型,以达到更好的效果。通过智能网联车的自动驾驶功能和速度优化模型的配合,结合GPOPS软件寻找出车辆在匝道冲突区域行驶的最优轨迹,减少车辆在高速公路下匝道路段中不必要的加速、减速等情况、减少能耗、保证安全且提高车辆通行效率。This paper aims to explore a new intelligent connected vehicle technology,which can effectively solve the delay problem caused by slowing down or even stopping the traditional vehicle when it merges into the ramp conflict area.The two-stage optimization model can also be realized by STM32 and other hardware in the vehicle-road coordinative environment to achieve better results.Through the coordination of the autonomous driving function of the intelligent connected vehicle and the speed optimization model,the optimal trajectory of the vehicle driving in the on-ramp conflict area is found in combination with the GPOPS software,so as to reduce the unnecessary acceleration and deceleration of the vehicle in the off-ramp section of the expressway,reduce energy consumption,ensure safety and improve vehicle traffic efficiency.
