PURPOSE: An electronic parking brake control method is provided to prevent ripple in a driving current generated by overlapping same phases by controlling to make a left control signal and a right control signal have the same pulse width and the opposite phase at the no-load state. CONSTITUTION: In an electronic parking brake control method, when the forward rotation of a left motor and a right motor is defined as an operating mode for stopping the drive of a wheel, if an electronic parking brake switch is changed from ON to OFF(S1,S2), a PWM control signal controlling each operation of right forward switching elements and left forward switching elements is applied to the right forward switching elements and the left forward switching elements in the opposite phase to drive the right motor and the left motor forward in a no-load section before a contact point where a brake disk pad makes contact with a disk pad(S4). |
