The invention discloses a composite brake anti-lock control system and a composite brake anti-lock control method, and belongs to the technical field of automobile brake anti-lock systems. Comprising a sensor unit, a wheel slip rate deviation calculation unit, an electronic mechanical brake ideal braking torque calculation unit, a power motor controller assembly and an anti-lock braking system assembly. The power motor controller assembly is connected with four power motors, each power motor is connected with a corresponding electronic mechanical brake, and the anti-lock braking system assembly comprises a fuzzy PID (Proportion Integration Differentiation) controller, a composite braking system and a torque distribution unit. When it is detected that the wheel slip rate tends to be locked, the electronic mechanical braking force is macroscopically adjusted to be close to the road adhesion limit firstly, meanwhile, fuzzy self-tuning PID control is adopted for adjusting the regenerative braking torque in a small range, the fluctuation of the wheel speed in the whole braking process is very small, and a vehicle has good braking smoothness.
