The invention discloses an ATO train control method for reducing train energy consumption, and relates to the technical field of train signal control. Comprising the following steps: a vehicle-mounted ATO system calculates a current target speed CurSbi and a predicted target speed PreSbi; identifying a target speed curve change model according to the continuous three-period operation change rule of the ATO system; according to the current target speed CurSbi and the current vehicle speed Vc, dynamic P coefficient overshoot control protection check is conducted on a PID controller, and if overshoot protection is met, the P coefficient of the PID controller is adjusted; and the vehicle-mounted ATO system calculates an expected output control instruction Rst0 of the current period according to the PID controller, the control instruction Rst0 is optimized based on the recognized target speed curve change model, and an output control instruction Rst1 is obtained. According to the method, the current control instruction is optimized and adjusted by recognizing the front target speed curve change model, output of unnecessary traction and braking is reduced, and train energy consumption is reduced.

    本发明公开了一种降低列车能耗的ATO控车方法,涉及列车信号控制技术领域。包括以下步骤:车载ATO系统计算当前目标速度CurSbi和预测目标速度PreSbi;根据ATO系统连续三周期运行变化规律,识别目标速度曲线变化模型;根据当前目标速度CurSbi和当前车速Vc对PID控制器进行动态P系数超调控制防护检查,若满足超调防护,则调节PID控制器的P系数;车载ATO系统根据PID控制器计算当前周期的预期输出控制指令Rst0,基于已识别出的目标速度曲线变化模型对控制指令Rst0优化,得到输出控制指令Rst1。本发明通过识别前方目标速度曲线变化模型,对当前控制指令进行优化调整,减少输出不必要的牵引和制动,降低列车能耗。
