摘　　要：防滑控制系统是和谐号动车组列车制动系统的核心技术之一.在列车高速运行时,具有防滑控制功能的列车制动控制系统,既能实现良好的滑行控制,又能充分利用轮轨之间的黏着作用力。主要介绍了和谐号动车组制动防滑系统,包括制动防滑系统的基本原理,硬件组成,滑行检测方法,防滑控制方法以及控制策略等。通过防滑试验验证了和谐号动车组制动防滑控制系统的有效性和可靠性。WSP control system is one of the core technologies for the high-speed EMU train brake system. During the train running at high speed, the brake control system with WSP function can not only achieve a good slide control, but also take advantage of adhesion force between wheel and rail. In this paper, the WSP brake system of China EMU is studied. The main contents are composed of the basic principles for WSP system, hardware components, sliding detection methods, WSP control methods and strategies. Finally, the validity and reliability of WSP brake control system is verified by means of the several real tests.
