The invention provides an electronic parking braking method and device, and relates to the technical field of vehicle braking. The method includes the steps that when a start parking braking command is received, a motor is controlled to rotate positively, whether brake calipers reach the contact surface of a brake disc or not is judged according to the first current value of the motor, and the first current value is the current value of the working current of the motor when the brake calipers do not reach the contact surface of the brake disc; when the brake calipers reach the contact surfaceof the brake disc, whether the brake calipers are tightly clamped or not is judged according to the second current value and the rotating speed value of the motor, and the second current value is thecurrent value of the working current of the motor when the brake calipers reach the contact surface of the brake disc; and when the brake calipers are tightly clamped, motor locking action is carriedout. According to the electronic parking braking method and device, reliability of electronic parking braking can be improved.
