Abstract
Disclosed are an electronic parking brake (EPB) system and a method of controlling the same. The EPB system includes a motor, a first Hall sensor configured to sense a current flowing through the motor, a second Hall sensor configured to sense a current flowing through the motor, and a controller configured to determine the motor to have a failure when a magnetic change of the first Hall sensor and a magnetic change of the second Hall sensor do not match a preset pattern during an apply operation of the motor.
