The invention provides a train automatic driving speed planning method and device. The method comprises the steps that train parameters are obtained; establishing a train kinematics model according to the train parameters; according to the train kinematics model, calculating the highest cruise speed of each speed limit interval of the train, and generating a first shortest ATO target speed curve; optimizing the comfort level of the first shortest time ATO target speed curve according to the current train operation condition, and generating a second shortest time ATO target speed curve; adjusting the cruising speed of each speed limit interval in the second shortest time ATO target speed curve according to the train operation timetable time, and generating a third shortest time ATO target speed curve; and controlling the train to run according to the third shortest time ATO target speed curve. The method is used for overcoming the defect that train automatic driving speed planning cannot be fully combined with real-time characteristics of a train in the prior art, and improvement of train automatic driving in the aspects of accurate control, energy-saving operation and riding comfort is achieved.

    本发明提供一种列车自动驾驶速度规划方法及装置,该方法包括:获取列车参数;根据列车参数建立列车运动学模型;根据列车运动学模型计算列车各限速区间的最高巡航速度,并生成第一最短用时ATO目标速度曲线;根据当前列车运行状况优化第一最短用时ATO目标速度曲线的舒适度,生成第二最短用时ATO目标速度曲线;根据列车运营时刻表时间调整第二最短用时ATO目标速度曲线中各限速区间的巡航速度,生成第三最短用时ATO目标速度曲线;根据第三最短用时ATO目标速度曲线控制列车运行。用以解决现有技术中列车自动驾驶速度规划未能充分结合车辆实时特性的缺陷,实现列车自动驾驶在精准控制、节能运行和乘坐舒适方面的提升。
