The invention discloses a rail vehicle, a rail vehicle brake control method and a rail vehicle brake control system, and relates to the technical field of rail vehicles. Calculating the theoretical deceleration of the corresponding carriage at the current moment according to the vehicle weight, vehicle speed, magnetic gap, braking current and ramp information of the corresponding carriage at the current moment, comparing the theoretical deceleration with a target deceleration, and maintaining the braking current when the absolute value of the difference between the theoretical deceleration and the target deceleration is less than or equal to a set value; the brake current is reduced when the theoretical deceleration is greater than the target deceleration and the absolute value of the difference between the theoretical deceleration and the target deceleration is greater than a set value, and the brake current is increased when the theoretical deceleration is less than the target deceleration and the absolute value of the difference between the theoretical deceleration and the target deceleration is greater than the set value. According to the rail vehicle braking control method, the problem that longitudinal impact force is generated between carriages in the eddy current braking process of the rail vehicle is solved.

    本申请公开了一种轨道车辆、轨道车辆制动控制方法和轨道车辆制动控制系统,涉及轨道车辆技术领域,轨道车辆制动控制方法包括:获取制动指令,根据对应车厢当前时刻的车重、车速、磁间隙、制动电流、坡道信息计算对应车厢在当前时刻的理论减速度,将理论减速度与目标减速度对比,当理论减速度和目标减速度的差的绝对值小于等于设定值时,则维持制动电流,当理论减速度大于目标减速度,且理论减速度和目标减速度的差的绝对值大于设定值时,则减小制动电流,当理论减速度小于目标减速度,且理论减速度和目标减速度的差的绝对值大于设定值时,则增大制动电流。上述轨道车辆制动控制方法解决了轨道车辆涡流制动过程中车厢间产生纵向冲击力的问题。
