The embodiment of the invention provides a distributed power train traction brake control method and device, and the method comprises the steps: obtaining the target acceleration of a train accordingto the current running speed of the train and a preset target speed; calculating a target traction force or a target braking force of each bullet train carriage based on a multi-mass-point kinetic equation according to the total mass, the running resistance and the inter-vehicle coupling force of each bullet train carriage in the train and the target acceleration of the train; and controlling eachbullet train carriage according to the target traction force or the target braking force of each bullet train carriage. According to the embodiment of the invention, the performance difference of each bullet train carriage in the train is fully considered, the inter-vehicle coupling force of each carriage is effectively reduced, the train stably runs, the mechanical life of the train is prolonged, and the comfort level of the train is improved.

    本发明实施例提供一种分布式动力列车牵引制动控制方法及装置,该方法包括:根据列车的当前行驶速度和预设目标速度,获取所述列车的目标加速度;根据所述列车中每节动车车厢的总质量、运行阻力、车间耦合力和所述列车的目标加速度,基于多质点动力学方程计算每节动车车厢的目标牵引力或目标制动力;根据每节动车车厢的目标牵引力或目标制动力,对每节动车车厢进行控制。本发明实施例充分考虑列车中各节动车车厢的性能差异,实现有效降低各节车厢的车间耦合力,使得列车平稳行驶,提高列车的机械寿命,提升列车的舒适度。
