The invention provides an electric wheel braking chatter prediction control system and method, and the system comprises a chatter prediction control unit which is used for obtaining an expected braking force signal, a wheel angular velocity signal and a hub motor angular velocity signal, predicting chatter, and calculating the braking pressure of a wheel cylinder and the compensation torque of a hub motor; and the electric wheel brake unit is interconnected with the flutter prediction control unit and is used for controlling the actions of a brake wheel cylinder and a hub motor so as to suppress flutter. According to the electric wheel braking chatter prediction control system and method, chatter can be actively predicted, chatter of a braking system is avoided by adjusting hydraulic braking force, and insufficient braking torque is compensated through motor torque.
