The invention discloses an anti-lock braking system control strategy design method based on an electronic mechanical braking system, and belongs to the field of automobile braking. The control strategy design method of the electronic mechanical braking system and the anti-lock braking system is integrated. According to the anti-lock braking system, the motor is controlled, the braking pressure of the wheels is actively adjusted, then the optimal slip rate is maintained, the wheels continuously obtain the peak longitudinal adhesive force and the large lateral adhesive force, and then the braking distance is shortened. In the strategy design method, the anti-lock braking system controller adopts the fuzzy control strategy based on the optimal slip rate of the wheels, real-time online closed-loop control of the optimal slip rate and the braking pressure is achieved by controlling the current variation of the execution motor of the electronic mechanical braking system, and the method has the advantages of being high in response speed, high in control precision, high in stability, high in reliability and the like. The efficiency is high.
