The invention relates to a rail vehicle anti-skid control method. The method comprises the steps that the deceleration a vehicle and the wheel deceleration a axle of a vehicle are obtained; when the acquisition value of the deceleration a vehicle of the vehicle is in a reasonable range, filtering processing is carried out on the deceleration a vehicle of the vehicle; measuring the axle speed of each axle, and determining the vehicle speed according to the comparison result of the wheel deceleration and the deceleration of the vehicle; the shaft speed is calculated according to a calculation formula of the slip rate, and a first ideal shaft speed and a second ideal shaft speed are determined according to the corresponding relation between the slip rate and the adhesion coefficient; and the measured shaft speed is compared with the first ideal shaft speed and the second ideal shaft speed, and air charging or air exhausting or pressure maintaining of the anti-skid valve is determined. According to the invention, the problem of inaccurate data source in the anti-skid control of the railway vehicle in the prior art is solved.

    本发明涉及一种轨道车辆防滑控制方法,该方法包括:获取车辆的减速度a车和轮减速a轴;当车辆的减速度a车的采集值在合理范围内时,对车辆的减速度a车进行滤波处理;测量各个轴的轴速,根据轮减速和车辆的减速度比较结果,确定车辆速度;根据滑移率的计算公式,计算出轴速度,并根据滑移率与粘着系数的对应关系,确定第一理想轴速和第二理想轴速;将测得的轴速与第一理想轴速和第二理想轴速比较,确定防滑阀充风或排风或保压。本发明解决了现有技术中轨道车辆防滑控制中数据来源不准确的问题。
