An electronic parking brake system includes an electronic parking brake (EPB) including a pair of brake pads disposed on both sides of a brake disc rotating with a rear wheel of a vehicle, a piston provided to press the pair of brake pads, a nut member provided to press the piston, a spindle member provided to move the nut member, and an electric motor configured to rotate the spindle member; a wheel speed sensor configured to detect a wheel speed of the rear wheel; a G sensor configured to detect a longitudinal acceleration of the vehicle; an accelerator pedal sensor configured to detect an operation of an accelerator pedal of the vehicle; an EPB switch configured to receive a parking apply command or a parking release command from a driver; and a controller configured to control the electric motor, wherein the controller is configured to determine whether a residual clamping force is present in the EPB based on a rear wheel speed or the longitudinal acceleration at a time of departure of the vehicle after parking is released, and when the residual clamping force is present, release the residual clamping force through an additional parking release control.
