The invention discloses an active rear-end collision prevention method for a subway train. The method comprises the steps that S1, the train continuously supervises the implementation condition of braking; s2, whether the train is subjected to emergency braking or not is judged; s3, if the train is subjected to emergency braking, whether the detected braking rate is sharply reduced or not is judged in the emergency braking process; s4, if the detected braking rate is sharply reduced, the train sends the detected information to an area control center; s5, the area control center judges whether a train exists in front of the train or not; s6, if a train is in front of the train, the area control center sends a collision risk to a front train ATS to prompt the front train; s7, after the front vehicle receives the collision risk reminding, whether the front vehicle meets the departure condition or not is judged; and S8, if the departure condition is met, the ATS of the front vehicle automatically triggers active rear-end collision prevention. The problem of rear-end collision of the front train and the rear train caused by insufficient braking force of the rear train due to slipping of the train in severe weather is solved.

    本发明公开了一种地铁列车的追尾主动预防方法,包括:步骤S1,列车持续监督制动的实施情况;步骤S2,判断列车是否发生了紧急制动;步骤S3,若列车发生了紧急制动,则在紧急制动过程中,判断检测到的刹车制动率是否急剧降低;步骤S4,若检测到的刹车制动率急剧降低,列车将检测到的信息发送给区域控制中心;步骤S5,区域控制中心判断该列车前方是否有列车;步骤S6,若该列车前方有列车,区域控制中心则将发出碰撞风险发送至前车ATS,提示前车;步骤S7,前车收到碰撞风险提醒后,判断自身是否满足发车条件;步骤S8,若发车条件,则前车ATS自动触发主动防追尾。解决了在恶劣天气下列车的打滑导致的后车刹车制动力不足,造成的前后列车追尾的问题。
