The invention discloses a train constant-speed control method and device, a railway vehicle and a medium, relates to the technical field of railway vehicles, is used for achieving constant-speed control over a train, and provides the train constant-speed control method aiming at the problem that at present, constant-speed control cannot be achieved when electric braking is insufficient or the train passes through a neutral section. The available total braking force in the constant-speed control mode is increased by adding air braking, so that the problem that the train cannot keep the constant speed when the electric braking is insufficient or the train passes through the neutral section and has no electric braking is solved. Moreover, the added air braking force is slightly larger than the gap of the electric braking force relative to the total braking force, enough dynamic adjustment space is reserved for the electric braking, and when train braking control is carried out, the braking requirement of a train can be met through random adjustment of the electric braking in the reserved dynamic adjustment space; and the total braking force does not need to be adjusted through air braking, so that the problems of accidents and the like caused by untimely train braking due to air braking are solved.

    本申请公开了一种列车恒速控制方法、装置、轨道车辆及介质,涉及轨道车辆技术领域,用于实现列车的恒速控制,针对目前在电制动不足或列车过分相时无法实现恒速控制的问题,提供了一种列车恒速控制方法,通过添加空气制动来增加恒速控制模式下可用的总制动力大小,以避免当电制动不足或者列车过分相无电制动时,列车无法保持恒速的问题。并且,上述添加的空气制动略大于电制动力相对于总制动力的缺口即可,为电制动保留了足够的动态调整空间,在进行列车制动控制时,可以通过电制动在保留的动态调整空间的任意调整,满足列车的制动要求,无需使用空气制动调节总制动力大小,也就不会因为空气制动导致列车制动不及时进而造成事故等问题的出现。
