The invention discloses a vehicle magnetic track braking control method and a vehicle magnetic track braking system.The vehicle magnetic track braking control method comprises the steps that when the air pressure at a train pipe meets a first condition, the deceleration of a vehicle is obtained in response to a braking instruction, and the air pressure of the train pipe is set to be larger than or equal to a first pressure set value according to the first condition; if the deceleration is smaller than a preset deceleration threshold value, electric braking force and/or air braking force are/is applied, and the adhesion coefficient of the current vehicle is obtained; and when the adhesion coefficient reaches a preset limit value and the obtained train speed is larger than or equal to a preset speed threshold value, the switch module is controlled to be switched on so that the air cylinder can be connected into the magnetic track brake. The braking force can be increased by adjusting the electric braking force and/or the air braking force, so that the deceleration of the vehicle is controlled to quickly meet the preset requirement; meanwhile, the adhesion coefficient of the vehicle and the train speed are obtained, and the magnetic braking force is output when the train speed is larger than or equal to the preset speed threshold value, so that the vehicle can be further controlled to decelerate under the condition that the adhesion coefficient does not exceed the limit value, and the vehicle can be braked more quickly and safely in the whole running process.
本发明揭示了一种车辆磁轨制动控制方法及车辆磁轨制动系统,包括在列车管处空气压力满足第一条件时,响应于制动指令,获取车辆的减速度,所述第一条件设定列车管空气压力大于等于第一压力设定值;若所述减速度小于预设减速度阈值,则施加电制动力和/或空气制动力并获取当前车辆的黏着系数;当所述黏着系数达到预设限制值且获取到的列车速度大于等于预设的速度阈值时,控制开关模块导通以使风缸接入磁轨制动器。本发明可以通过调整电制动力和/或空气制动力来增加制动力从而控制车辆减速度快速达到预设要求;同时还获取车辆的黏着系数和列车速度,在列车速度大于等于预设的速度阈值时输出磁制动力,从而可以保证黏着系数不超过限制值的情况下进一步控制车辆减速,如此在整个车辆运行过程中可以更快、更安全地制动。
