The invention provides a deceleration strip working condition vehicle-road cooperative energy feedback method in an Internet of Vehicles environment, which comprises the following steps: in a deceleration strip working condition automatic driving mode, when a vehicle passes through a fixed position P0 and runs at a constant speed for ts time, braking at a 0.1 g braking deceleration, and after switching to a manual driving mode, feeding back an optimal vehicle speed and the braking deceleration to a driver by an ECU (Electronic Control Unit); a driver controls the force of a brake pedal, so that the optimal vehicle speed and brake deceleration are achieved; a fitness function integrating vehicle dynamics performance and energy recovery performance is established, the minimum fitness function is used as an optimization condition, the optimized vehicle speed of the vehicle passing through the electromagnetic deceleration strip is obtained, and then the optimal vehicle speed is determined according to the optimized vehicle speed; the braking deceleration is determined according to the size relation between the actual distance between the vehicle and the electromagnetic deceleration strip and the ideal braking distance and the critical braking distance. According to the invention, vehicle-road cooperation energy feedback optimization is realized.

    本发明提供了一种车联网环境下的减速带工况车路协同馈能方法,在减速带工况自动驾驶模式,经过固定位置P0处时,车辆匀速行驶,ts时间后,以0.1g的制动减速度进行制动,切换为人工驾驶模式后,ECU将最佳车速和制动减速度反馈给驾驶员,驾驶员控制制动踏板力度,从而达到最佳车速和制动减速度;通过建立综合车辆动力学性能和能量回收性能的适应度函数,以适应度函数最小作为寻优条件,得到车辆通过电磁减速带的优化车速,再由优化车速确定最佳车速;制动减速度根据车辆到电磁减速带的实际距离与理想制动距离、临界制动距离的大小关系进行确定。本发明实现了车路协同馈能最优。
