The invention provides a train downhill air brake adjusting method and system. The method comprises the steps that a reference speed curve is determined; an air braking speed threshold value is determined; and according to comparison of the sum of the current train speed and the air braking speed threshold value of the train and the reference speed, applying or cancelling of air braking of the train is adjusted. The cruise lower bound is adjusted according to the air charging time, the air discharging time and the downhill gradient value to ensure the smoothness of level output, application and revocation of air braking can be evaluated more accurately, the smoothness of air braking output is ensured, and meanwhile, the stability of the level output is improved. And the formed electric braking and air braking switching strategy has good effects on reducing longitudinal impulse in the train running process and improving the train running stability, and it is guaranteed that the train safely and efficiently passes through lines with complex road conditions.

    本发明提出一种列车下坡空气制动调节方法、系统,方法包括:确定参考速度曲线;确定空气制动速度阙值;根据列车当前车速和空气制动速度阙值的求和与参考速度的比较,调节列车空气制动的施加或撤销。根据充风和放风时间以及下坡坡度值调节巡航下界保证级位输出的平缓性,能够对空气制动的施加和撤销进行更为准确的评估,保证空气制动输出的平缓性,同时,还能够形成的电制动、空气制动切换策略对减小列车运行过程中的纵向冲动和提高列车运行的平稳性有良好的效果,保障了列车安全高效通过路况复杂的线路。
