An electronic parking brake system comprises: an electronic parking brake having a pair of brake pads disposed on both sides of a brake disk rotated with a rear wheel of a vehicle together, a piston provided to compress the brake pad, a nut member provided to compress the piston, a spindle member provided to move the nut member, and a motor rotating the spindle member; a current sensor detecting a current of the motor; and a control unit controlling the motor to perform parking operation with respect to the electronic parking brake. The control unit detects an inrush current flowing the motor through the current sensor during parking operation and determines whether there is low-voltage failure based on the detected inrush current.
