Anti-lock braking control method and system and electromechanical braking device

The invention discloses an anti-lock braking control method and system and an electromechanical braking device. According to the anti-lock braking control method, only the angular acceleration of wheels needs to be measured, a vehicle is made to conduct reciprocating running of deceleration and acceleration during braking through a continuous control period, the wheels are prevented from being locked, and the braking distance is shortened; according to the electromechanical braking device, the braking torque applied to the brake is converted into the acting force on the brake pad according to the lever principle, braking is achieved through the braking wedge block, force transmission is completed through a mechanical structure, a complex hydraulic power device is not needed, and compared with a conventional electro-hydraulic braking device, the electromechanical braking device is simpler in structure and lower in cost. When used for anti-lock braking, the pedal vibration is avoided, the braking torque control
