The invention discloses an automobile anti-lock control method based on an electronic mechanical braking device, which comprises a vehicle single-wheel model, slip rate calculation, road adhesion coefficient calculation, expected slip rate, an ABS controller and the electronic mechanical braking device, and realizes closed-loop control of braking torque by controlling the wheel slip rate, so that the braking distance can be effectively shortened, and the braking efficiency is improved. And the driving safety of the vehicle is improved. According to the electronic mechanical braking device, a planetary speed reducing mechanism and a ball screw pair serve as a transmission mechanism for motor output torque, finally, a piston pushes a braking block to complete braking, a traditional hydraulic device is abandoned structurally, transmission is more stable, control is more accurate, and the emergency braking efficiency of a vehicle can be improved.
