摘　　要：分析了城轨车辆制动防滑系统常用的速度差、减速度等滑行检测判据的弊端,对速度差中车辆参考速度的计算和减速度检测灵敏度太高提出改进建议,对比分析2种不同防滑策略恢复时机的选择对防滑效率及参考速度的影响,结合两者优势,给出一种较优的防滑策略。Based on the weakness analysis of the traditional wheel-slip detect methods such as speed difference and decelerationcriterion, proposals were given for the reference speed calculation and over sensitive caused by deceleration-criterion. At the same time, two different strategy of anti-slide recovery were compared, and their influence on the anti-slide efficiency and reference speed was analyzed. Finally, a new combined WSP strategy with both advantages is suggested.
