The invention provides an anti-skid method and system in the train braking process, and the method comprises the steps: determining a target wheel which slips in the train braking process according to the speeds of all wheels in the train braking process and a current speed reference value; the initial braking force borne by the target wheel is reduced, and when the absolute value of the difference value between the speed of the target wheel and the current speed reference value is equal to a first preset threshold value, the braking force borne by the target wheel is increased till the braking force borne by the target wheel is equal to the initial braking force. The system executes the method. According to the method, the difference of the braking force applied to each wheel of the train in the braking process is fully considered, after a certain wheel slips, the problem is found through the difference value abnormity between the wheel and the current speed reference value, and the braking force of the slipped wheel is automatically adjusted to the optimal state through feedback adjustment; the optimal adhesive force is obtained, and the sliding phenomenon in the train braking process is effectively prevented.
本发明提供一种列车制动过程防滑方法及系统,方法包括:根据列车制动过程中所有车轮的速度以及当前速度基准值,确定列车制动过程中发生打滑的目标车轮;降低目标车轮受到的初始制动力,并在所述目标车轮的速度与当前速度基准值之间的差值的绝对值等于第一预设阈值时,增加目标车轮受到的制动力,直至目标车轮受到的制动力等于初始制动力。所述系统执行所述方法。本发明充分考虑了列车各个车轮在制动过程中受到制动力存在的差异性,在出现某一车轮打滑后,通过与当前速度基准值之间的差值异常发现问题,并通过反馈调节将发生打滑的车轮的制动力自动调整回最佳状态,使其获得最佳的黏着力,有效防止列车制动过程中滑行现象的发生。
