The invention provides a deceleration closed-loop control method and device, and relates to the field of railway vehicle mechanical control. Determining the brake cylinder pressure of the locomotive vehicle brake system by using a pre-constructed friction coefficient calculation model; wherein the required deceleration is sent by an automatic driving system; the actual deceleration is obtained through actual measurement; and the brake cylinder pressure acts on the brake system to achieve deceleration closed-loop control. According to the method, the current deceleration state of the train can be obtained in real time and compared with the target deceleration, so that the brake cylinder pressure is adjusted in real time, and the deceleration efficiency is improved.

    本申请提供一种减速度闭环控制方法及装置,涉及轨道车辆机械控制领域,包括:当制动指令中的需求减速度与机车车辆的实际减速度之间的差异大于预设的阈值时,利用预先构建的摩擦系数计算模型确定所述机车车辆制动系统的制动缸压力;其中,所述需求减速度由自动驾驶系统发出;所述实际减速度由实际测量得到;将所述制动缸压力作用于所述制动系统,以实现减速度闭环控制。本申请能够实时获得列车当前的减速度状态,并与目标减速度进行比较,从而实时调整制动缸压力,以提升减速度效率。
