The invention discloses a train constant-speed control method. The method comprises the steps that whether a first difference value between the preset speed and the current speed of a target train islarger than a first preset threshold value or not is judged; if the first difference value is smaller than or equal to the first preset threshold value, whether the second difference value is larger than a second preset threshold value or not is judged, wherein the second difference value is the difference value between the traction force theoretically output by the traction system of the target train and the currently output traction force; and if the second difference value is larger than a second preset threshold value, the traction system is controlled to keep the currently output tractionforce, so that the target train keeps running at a constant speed. Obviously, by means of the method, the overspeed problem of the target train in the running process can be avoided. Correspondingly,the train constant-speed control device, medium and equipment disclosed by the invention also have the above beneficial effects.

    本申请公开了一种列车恒速控制方法,包括:判断目标列车的预设速度与当前速度的第一差值是否大于第一预设阈值;若第一差值小于或等于第一预设阈值,则判断第二差值是否大于第二预设阈值;其中,第二差值为目标列车的牵引系统理论输出的牵引力与当前输出的牵引力的差值;若第二差值大于第二预设阈值,则控制牵引系统保持当前输出的牵引力,以使目标列车保持恒速运行。显然,通过本申请中的方法,可以避免目标列车在运行过程中出现的超速问题。相应的,本申请公开的一种列车恒速控制装置、介质及设备,同样具有上述有益效果。
