The invention provides a rail train wheel-rail adhesion control method. The rail train wheel-rail adhesion control method comprises the steps of inputting a creep signal into an electromagnetic torquesignal of a traction motor; detecting a speed signal of the traction motor and a torque current signal of the traction motor; obtaining the phase of the speed signal and the phase of the torque current signal; inputting the phase of the speed signal and the phase of the torque current signal into a linear controller, and calculating the phase difference between the phase of the speed signal and the phase of the torque current signal by the linear controller; and controlling the phase difference between the speed signal and the torque current signal to be equal to a preset value by the linearcontroller. The traction motor can be detected and controlled in real time, and wheel-rail idling and sliding are avoided.
