The invention discloses a method for generating a train automatic driving virtual curve under a complex road condition, which comprises the following steps of: digitally processing a road section to divide the road section into a plurality of driving sections, and assigning a section length sequence according to the actual condition of the road section; and each section generates a section train driving speed sequence according to the driving demand of the section. Based on the requirements of different running speeds of a train in an interval, an acceleration sequence in the interval is set and provided, and various acceleration schemes can be selected in each speed change process. Traversing all the combination schemes of the train driving speed sequence and the acceleration sequence, and redistributing the distribution speed sequence and the acceleration sequence of each section to form a curve parameter data set. Calculating and adjusting the constant-speed running time of the train in each constant-speed running section and the corresponding speed change process time so as to obtain an initial driving curve; and an actual driving curve is formed after the compensation distance calculation error is optimized. According to the method, more driving scheme selections can be provided for train driving.

    本发明公开一种复杂路况的列车自动驾驶虚拟曲线的生成方法,对路段进行数字化处理以将路段划分为若干行驶区段,根据路段实际情况对区段长度序列进行赋值。每一个区段按照区段的驾驶需求生成区段列车驾驶速度序列。基于区间内列车行驶不同速度的要求,设定并提供区段内加速度序列每次变速过程中有多种加速度方案可供选择。对列车驾驶速度序列和加速度序列的所有组合方案进行遍历,重新分配每一区段的分配速度序列和加速度序列,形成曲线参数数据集。计算并调整每一个匀速行驶区段的列车匀速行驶时间以及对应的变速过程时间,进而得到初始驾驶曲线;优化补偿距离计算误差后形成实际驾驶曲线。本发明的方法能够为列车驾驶提供更多的驾驶方案选择。
