摘　　要：自动列车驾驶系统ATO通过对列车的速度调节实现列车在站间的自动运行,列车在站间的控制策略决定其运行的能耗。传统的ATO可以根据线路情况、列车当前速度、位置、牵引制动特性以及停车点的位置计算相应的速度曲线,通过一定的控制算法实现对列车速度的精确追踪,保证列车准点并精确地到达停车点。但是该过程使得列车在站间运行时反复实施牵引力和制动力的转换,能耗较大。本文在传统ATO控制策略的基础上,分析一种基于驾驶策略的ATO控制方法,给出一种ATO节能驾驶策略的求解算法。该算法在保证列车到站时间误差在一定范围的前提下,通过延长列车的惰行距离,减少列车在站间运行的能耗。The ATO system realizes automatic train operation between stations by controlling the train speed.The inter-station driving strategy determines the energy consumption for towing the train.The traditional ATO system can calculate a speed profile according to the infrastructure data,current train speed,current train position,the traction and braking characteristics,the target speed and target position,and then precisely track the speed profile with classic control principles.It has good performance of punctuality and stopping precision.However,the train may switch between acceleration and braking during tracking the target speed,which costs a lot of energy.We proposed a control principle based on the current ATO system by controlling the driving strategy and present an algorithm to solve the optimal driving strategy.The algorithm can prolong the coasting distance and save the energy consumption under the precondition that the train delay is acceptable.
