The invention discloses a rail transit driving curve planning method and system based on multi-source sensing data. The rail transit driving curve planning method comprises the steps that a running route of a train is divided into a plurality of intervals; detecting the current running position of the train during the running period of the train, and calculating a control sequence u2 (k) of the interval qi and the real-time optimization energy consumption Jsi of the interval qi based on various sensing data of the train if the train is found to run to the boundary close to any interval qi; comparing the real-time optimization energy consumption Jsi with the experience optimization energy consumption Jyi preset in the interval qi, and if the real-time optimization energy consumption Jsi is superior to the experience optimization energy consumption Jyi, selecting a control sequence u2 (k) to control the train to run in the interval qi; otherwise, keeping a preset control sequence u1 (k) corresponding to the empirical optimization energy consumption Jyi to control the train to run in the interval qi. According to the method, the actual energy consumption requirement of train operation can be met, the performance energy consumption of the train is reduced, the train operation cost is reduced, and the method has great significance in research on train energy-saving driving optimization.

    本发明公开了一种基于多源感知数据的轨道交通驾驶曲线规划方法及系统,本发明包括将列车的行驶线路划分为多个区间;在列车运行期间检测列车当前的行驶位置,若发现列车当前行驶到临近任意区间qi的边界则基于列车的多种感知数据计算区间qi的控制序列u2(k)及其实时优化能耗Jsi;将实时优化能耗Jsi及其区间qi预设的经验优化能耗Jyi进行比较,若实时优化能耗Jsi优于经验优化能耗Jyi,则选择控制序列u2(k)控制列车在区间qi的行驶;否则,保持经验优化能耗Jyi对应的预设控制序列u1(k)控制列车在区间qi的行驶。本发明能够满足列车运行的实际能耗需求,降低列车的性能能耗,降低列车运营成本,对于研究列车节能驾驶优化具有较大意义。
