An anti-slip control method and apparatus, and an anti-slip control system are provided, and may be applied to an electric vehicle, an intelligent vehicle, a new energy vehicle, and the like. The method includes: performing filtering on a rotation speed signal of a motor in a vehicle to obtain a first disturbance signal, where the first disturbance signal is a signal that causes motor rotation speed disturbance in the motor; performing, based on a pre-stored motor rotation speed dead zone, dead zone processing on the first disturbance signal to obtain a second disturbance signal, where the motor rotation speed dead zone includes an amplitude of a non-jitter rotation speed signal in the rotation speed signal; calculating disturbance compensation torque of the motor based on the second disturbance signal; calculating first motor torque based on a slip rate of a driving wheel, where the driving wheel is a wheel driven by the motor; and compensating for the first motor torque by using the disturbance compensation torque, to obtain second motor torque, where the second motor torque is used by the motor to drive the driving wheel. This helps prevent vehicle slipping in time when vehicle jitter is suppressed.
