According to the ramp anti-slip control method and system for the multi-marshalling rubber wheel electric train, the slope starting torque is predicted through the motor feedback torque and the instantaneous acceleration calculated value, the train does not need a ramp sensor, and the implementation cost of the ramp anti-slip function is reduced; the train is driven in a distributed mode, the stalling time of the motors is shortened through grouping of the control motors and torque polling control, the temperature rise of the motors is optimized, and the service life of the motors is prolonged. And real-time monitoring of the moment in the anti-slip process is carried out, the minimum starting moment is determined, and the anti-slip exit time is determined. The starting anti-slip strategy and the out-of-control control strategy of the motor improve the safety of the system.
