The invention discloses a maglev train and a braking control method and system thereof, which are applied to the technical field of rail transit, and the method comprises the following steps: determining a braking force target value according to braking level information; when the electric braking force is effective, after the braking force target value is distributed, an electric braking device and a mechanical braking device are controlled to apply the distributed electric braking force and mechanical braking force respectively; when the electric braking force is invalid, distributing the braking force target value as mechanical braking force and applying the mechanical braking force; determining the actual deceleration of the running direction of the maglev train based on the slope angle information of the current position of the maglev train and the deceleration signal of the maglev train detected by the accelerometer; when an error between the target deceleration and the actual deceleration is greater than a compensation trigger threshold value, a compensation amount for eliminating the error is determined based on the error and the braking force target value is adjusted by the compensation amount. By means of the scheme, accurate braking control over the maglev train can be achieved, the braking effect can be guaranteed, and driving safety is improved.

    本申请公开了一种磁浮列车及其制动控制方法和系统,应用于轨道交通技术领域,包括:根据制动级别信息确定出制动力目标值;电制动力有效时,进行制动力目标值的分配后,控制电制动装置和机械制动装置分别施加分配的电制动力和机械制动力;电制动力无效时将制动力目标值分配为机械制动力并施加机械制动力;基于磁浮列车当前所处位置的坡角信息以及加速度计检测的磁浮列车减速度信号,确定磁浮列车行车方向的实际减速度;当目标减速度与实际减速度之间的误差大于补偿触发阈值时,基于该误差确定出用于消除误差的补偿量并通过补偿量调整制动力目标值。应用本申请的方案可以实现磁浮列车的准确的制动控制,也就有利于保障制动效果,提高了行车安全。
