The invention discloses a target speed calculation method fusing the actual operation capability of a train. The method comprises the following steps: obtaining the real-time traction and braking states of the train; in the cruising and coasting stages, the ATO calculates and updates the minimum difference value which can be reached by the current maximum limiting speed and the EB limiting speed in real time according to the traction capacity of a train, and generates an ATO maximum operation target curve according to the minimum difference value; in the braking stage and the stopping stage, if partial braking of the train is lost, the braking capacity is reduced, and the ATO adjusts the braking curve and the stopping curve in real time according to the current braking capacity of the train. According to the method, the curve can be planned in advance according to the real-time traction and braking states, lag control caused by speed feedback is prevented, and the cruising speed and the traveling speed can be improved and the traveling interval can be shortened in the interval cruising stage by utilizing the traction characteristics.

    本发明公开了一种融合车辆实际运行能力的目标速度计算方法,包括如下步骤:获取列车实时的牵引、制动状态;在巡航和惰行阶段,ATO根据列车的牵引能力来实时计算和更新当前最高限制速度和EB限制速度可达到的最小差值,并根据最小差值生成ATO最高运行目标曲线;在制动阶段和站停阶段,如果列车有部分制动的丢失,带来了制动能力的下降,ATO根据列车当前的制动能力来实时调整制动和站停曲线。本发明可以根据实时的牵引和制动状态,提早规划曲线,防止速度反馈带来的滞后控制,并且可以利用牵引特性,在区间巡航阶段提高巡航速度,提升旅行速度,缩短行车间隔。
