The invention provides a dynamic marshalling method applied to virtual marshalling, and the method comprises the steps: obtaining a marshalling interval in response to a dynamic marshalling command, and enabling adjacent trains to establish train-to-train communication so as to obtain the information of a front train and a rear train in the adjacent trains; based on the obtained information of the front vehicle and the rear vehicle, constructing a first optimization target meeting a virtual marshalling constraint condition by taking accurate marshalling and low energy consumption as targets, and calculating an optimal control strategy in a virtual marshalling process and an offline speed curve corresponding to the optimal control strategy based on the first optimization target by adopting a dynamic planning method; the rear vehicle is controlled to run according to an off-line speed curve based on the optimal control strategy, the running condition of the rear vehicle is monitored in real time in the running process of the rear vehicle, and when the actual running speed curve of the rear vehicle deviates from the off-line speed curve, the optimal control strategy and the speed curve of the follow-up stage are calculated and updated through a sequential quadratic programming method. And the rear vehicle controls the rear vehicle based on the updated optimal control strategy.

    本发明提供一种应用于虚拟编组的动态编组方法,所述方法包括:响应于动态编组的命令,获取编组区间并使相邻列车建立车车通信以获取相邻列车中前车和后车信息;基于获取的前车和后车信息,以精确编组和低能耗为目标构建满足虚拟编组约束条件的第一优化目标,采用动态规划方法基于所述第一优化目标计算虚拟编组过程中的最优控制策略以及最优控制策略对应的离线速度曲线;后车基于所述最优控制策略控制后车按照离线速度曲线运行,并在后车运行过程中实时监控后车运行情况,在后车实际运行速度曲线偏离所述离线速度曲线时,采用序列二次规划方法计算并更新后续阶段的最优控制策略和速度曲线,后车基于更新后的最优控制策略控制后车。
