The invention discloses an electric-pneumatic combined braking method for a train, which comprises the following steps of: S1, acquiring the current train speed by a control system, judging whether the current train speed exceeds a set threshold value or not, if the current speed exceeds the set threshold value, sequentially executing the steps S2-S4, and if the current speed does not exceed the set threshold value, sequentially executing the steps S5-S6; s2, an air brake is started for braking, and the air brake is kept for T1 time; s3, starting motor braking; s4, after motor braking is kept for T2 time, air braking is relieved, motor braking is kept till train deceleration is smaller than a set threshold value, and the step S5 is executed; s5, an air brake is started for braking; and S6, after air braking is kept for T3 time, motor braking is unloaded, and air braking is continuously kept till the train speed is reduced to zero. Through combination of motor braking and air braking, the problem that a brake shoe is prone to abrasion is solved, the braking process is smooth, and damage to a gearbox is avoided.

    本发明公开了一种列车电空联合制动方法,S1.控制系统采集当前列车速度,并判断当前列车速度是否超过设定阈值,若当前速度超过设定阈值,则依次执行步骤S2‑S4,若未超过设定阀值,则依次执行步骤S5‑S6;S2.启动空气刹车制动,并保持空气制动T1时间;S3.启动电机制动;S4.保持电机制动T2时间后缓解空气刹车制动,保持电机制动直至列车减速小于设定阈值,执行步骤S5;S5.启动空气刹车制动;S6.保持空气制动T3时间后卸载电机制动,持续保持空气刹车制动直至列车速度减速为零。本发明通过联合电机制动和空气刹车制动,解决了闸瓦容易磨损的问题,且制动过程平滑顺畅,不会对齿轮箱造成损伤。
