The invention discloses a CAV ecological driving guiding method based on vehicle-road cooperation in a mixed traffic environment. The method comprises the following steps: 1, collecting vehicle information at a t0 moment and a real-time state of a signal lamp at a current intersection; 2, judging the position of a traffic scene where the CAV is located; 3, determining a terminal state of CAV ecological driving according to different traffic scenes; 4, determining an optimal speed trajectory curve of the CAV; and 5, dynamically updating and optimizing the track through a trigger type track updating rule. Through information interaction between the CAVs and the roadside facilities and between the CAVs in the vehicle-road coordination environment, the phenomena of starting, stopping, idling, acceleration and deceleration of the CAVs at the intersection can be reduced, so that the traffic efficiency is improved, the energy consumption is reduced, and the sustainable development of traffic is realized.

    本发明公开了一种混合交通环境下基于车路协同的CAV生态驾驶引导方法,包括:1、采集t0时刻的车辆信息与当前交叉口信号灯实时状态;2、判断CAV所处的交通场景位置;3、依据不同的交通场景确定CAV生态驾驶的终端状态;4、确定CAV的最佳速度轨迹曲线;5、通过一种触发式的轨迹更新规则,动态进行轨迹的更新和优化。本发明能够通过车路协同环境下CAV与路侧设施、CAV与CAV之间的信息交互,减少CAV在交叉口启停、怠速和加减速现象,从而提高交通效率与减少能源消耗,实现交通的可持续发展。
