The invention provides an adhesion control method for a rail transit train, and relates to the technical field of rail transit traction control, and the method comprises the steps: obtaining the current adhesion coefficient and creep speed of a target rail transit train; according to the adhesion coefficient and the creep speed, determining a reference creep speed corresponding to the target rail transit train, and a slope and an intercept currently corresponding to an adhesion characteristic curve of the target rail transit train; determining an optimal motor torque corresponding to the target rail transit train according to the creep speed, the reference creep speed, the slope, the intercept, and a preset target function and constraint conditions of a train dynamics model; and completing adhesion control of the target rail transit train according to the optimal motor torque corresponding to the target rail transit train. The reliability of adhesion control can be improved, and then stable operation of the train is guaranteed.
