The invention discloses a traction control method and system for a rail transit train, relates to the technical field of rail transit trains, and is used for reasonably distributing traction force of a target rail transit train. According to the method, initial distribution of vehicle-vehicle traction force is reasonably carried out according to the creep rate of each wheel set, and traction distribution between shafts is dynamically adjusted by combining the creep rate and the acceleration of each wheel set. According to the traction control method disclosed by the invention, adhesion redundancy between the train and the train and between the axle and the axle is fully utilized, so that the traction force distribution mode is more reasonable, the phenomenon of frequent slipping or idling of part of wheel pairs of the train is emphatically solved, the intervention frequency of a train creep control system is greatly reduced, and traction exertion and stable operation of the train in operation are ensured.
本申请公开了一种轨道交通列车的牵引控制方法和系统,涉及轨道交通列车技术领域,用于合理分配目标轨道交通列车的牵引力。该方法不仅根据各个轮对的蠕滑率合理地进行了车‑车牵引力的初次分配,还结合各个轮对的蠕滑率和加速度动态调整各个轴之间的牵引分配。本申请公开的牵引控制方法充分利用车‑车和轴‑轴之间的粘着冗余,使得牵引力分配方式更加合理,着重解决列车部分轮对频繁打滑或空转的现象,大幅减少了列车蠕滑控制系统介入的频次,保证列车在运营中的牵引发挥和稳定运行。
