The invention is suitable for the field of rail transit, and provides a train braking curve determining method and device and a train control method and system, and when a segmented deceleration model is used for calculating a braking curve, corrected average deceleration is used in a first-level speed interval. The average deceleration is closer to the overall deceleration capacity of the whole section, the braking distance obtained through calculation is closer to the real braking distance, the tracking interval is reasonable, and the railway transportation efficiency can be improved; meanwhile, the corrected average deceleration is adopted, the braking distance obtained through calculation is not smaller than the real braking distance under any condition, rear-end collision of the train is avoided, and absolute driving safety is guaranteed. Therefore, according to the train braking curve determining method, on the premise that safety is guaranteed, railway transportation efficiency is improved, and unification of safety and efficiency is achieved.

    本发明适用于轨道交通领域,提供了一种列车制动曲线确定方法及装置、列车控制方法及系统,在使用分段减速度模型计算制动曲线时,一级速度区间内使用经过校正的平均减速度。平均减速度更接近整个分段整体的减速能力,计算得到的制动距离更接近真实的制动距离,追踪间隔合理,可以提高铁路运输效率;同时,采用经过校正的平均减速度,计算得到的制动距离在任何情况下不小于真实的制动距离,列车不会发生追尾事故,保证绝对的行车安全。因此,本发明提出的列车制动曲线确定方法,在保证安全的前提下,提高了铁路运输效率,实现安全和效率的统一。
