The invention discloses a target speed curve optimization method for collaborative energy-saving operation of passenger and freight collinear trains. The method comprises the following steps: step 1, establishing a simple substance point kinematics model of a train; and step 3, solving the GPOPS toolbox. Compared with the prior art, the method has the following advantages and effects: (1) aiming at different operation conditions of the passenger train and the freight train, different objective functions are designed: the optimization objective of the passenger train is to reduce the traction energy consumption and improve the punctuality rate, and the optimization objective of the freight train is to reduce the traction energy consumption and shorten the cargo transportation time; and (2) target speed curve optimization of the passenger train and the freight train is comprehensively considered, and the optimized result can improve the operation efficiency of the passenger train and the freight train at the same time.

    本发明公开一种客货共线列车协同节能运行的目标速度曲线优化方法,包括步骤1:建立列车的单质点运动学模型;步骤3:GPOPS工具箱求解。较现有技术而言,具有如下优点及功效:(1)针对客运列车和货运列车不同的运营情况,设计了不同的目标函数:客运列车的优化目标是降低牵引能耗和提高准点率,货运列车的优化目标是降低牵引能耗和减少货物运输时间。(2)综合考虑了客运列车和货运列车的目标速度曲线优化,优化后的结果可以同时提高客运列车和货运列车的运营效率。
