Wheel-slide-protection control is one of the core technologies for the high-speed EMUs brake system. The effective and reliable wheel-slide-protection strategy can not only avoid the wheel tread flat, and protect the safety of the vehicle equipments, but also can take advantage of adhension force between wheel and rail to guarantee braking distance. The basic mechanism of EMUs was introduced from the relationship between the brake force and adhension force, and combining the standard of UIC 541-05, the wheelslide- protection strategy of the latest EMUs in China was presented, including the wheel-slide detection method, anti-skid method, fault detection and safety-oriented, detection of non-rotating axles, and the method of adhesion increase. Finally, the validity and reliability of WSP brake control system was verified by means of the real tests.
