The invention discloses a method, a device, equipment and a medium for ensuring degradation operation safety of a train, and relates to the technical field of vehicle control. The method comprises the steps that when a train is started based on a degradation mode, a current-level traction force is applied to the train according to a traction instruction representing that the train runs in the current running direction; when the accelerated speed corresponding to the traction force of the current level enables the train to exceed a starting speed threshold value, a multi-level adjusting function is started; and starting an emergency braking function according to the polarity of the motor torque direction and the current running direction. Whether the train slides or not is determined through the polarity of the motor torque direction and the polarity of the current running direction, when the train slides, emergency braking is conducted in time so as to ensure train safety, and meanwhile, when the accelerated speed corresponding to the current-level traction force enables the train to exceed the starting speed threshold value, the multi-level adjusting function is started, and the train safety is guaranteed. Therefore, the problems that the traction force cannot be adjusted, discomfort is caused to a user, and operation is difficult are solved, and train operability and comfort are achieved.

    本申请公开了一种保证列车降级运行安全的方法、装置、设备及介质,涉及车辆控制技术领域。该方法包括:当基于降级模式启动列车时,根据表征列车按照当前运行方向运行的牵引指令对列车施加当前级位牵引力;在当前级位牵引力对应的加速度使得列车超过启动速度阈值时,启动多级位调节功能;根据电机转矩方向和当前运行方向的极性开启紧急制动功能。通过电机转矩方向和当前运行方向的极性确定列车是否溜车,当列车溜车时,及时紧急制动,以确保列车安全,同时,在当前级位牵引力对应的加速度使得列车超过启动速度阈值时,启动多级位调节功能,以便于克服牵引力无法调节对用户造成的不适以及难于操作的问题,以此实现列车可操作性和舒适性。
