The invention relates to a train speed limit determination method of a train safety braking curve model, and belongs to the field of train control. When a train safety braking curve model is used for calculating the non-breakthrough speed of a train, the change rate k is introduced during t1 stage calculation, and the speed at the end of the t1 stage and the movement distance of the t1 stage are calculated in a second-order mode. The method is used for urban rail transit, and when the vehicle movement authorizes to calculate the non-breakthrough speed of the train, the vehicle running speed is increased and the urban rail transit running efficiency is improved on the premise of ensuring safety, so that the operation cost is saved, and the transport capacity is improved.

    本发明涉及一种列车安全制动曲线模型的列车限速确定方法,属于列车控制领域。本发明在使用列车安全制动曲线模型计算列车不可突破速度时,在t1阶段计算时,引入变化率k,采用二阶的方式计算t1阶段结尾时速度和t1阶段运动距离。本发明用于城市轨道交通,在车辆移动授权计算列车不可突破速度时,在保证安全的前提条件下提高车辆运行速度,提高城市轨道交通运行效率,从而节约运营成本,提高运力。
