Control system and control method for wheel rail braking

A control system for wheel rail braking comprises a control calculation unit. Comprising a control calculation unit, an anti-skid valve and a brake cylinder. The control calculation unit is provided with a speed difference threshold value, and the value of the speed difference threshold value is set to enable an adhesion force coefficient value in the braking process to enter an adhesion re-rising stage after a first peak point; and when the actual speed difference in the braking process is larger than or equal to the threshold value of the speed difference, the system is triggered to execute braking skid resistance, the control calculation unit sends out an instruction, and the instruction is that an anti-skid valve is opened, the pressure of a brake cylinder is reduced, and an air exhaust stage is started. By setting the threshold value of the speed difference, the adhesion curve has an adhesion re-rising stage along with the increase of the creep rate, and the bullet train can be braked by utilizing an adh
