Abstract
The disclosure presents a control method for an electric braking device which includes a brake switch, a pushing force sensor, a thrust sensor, and an electric motor which moves a pad thrust member in a direction in which the pad thrust member approaches to a rotor rotating with the vehicle wheel associated therewith, thereby performing a braking operation. In the control method, a brake target value as computed by using an output signal of the pushing force sensor is compared with a threshold value as set to a minute braking force when the brake switch is in an on state. When the brake target value is below the threshold value, the electric motor is controlled with a predetermined value as the target value, and after the brake switch is turned off, the electric motor is rotated for a predetermined time to retract the pad thrust member.
