The present invention relates to an electronic parking brake system and a control method thereof. The electronic parking brake system according to a preferred embodiment of the present invention comprises: a first motor for a parking brake of a first wheel of a vehicle; a second motor for the parking brake of a second wheel of the vehicle; a control unit generating a control signal for controlling the first motor and the second motor; and a motor drive unit driving the first motor and the second motor according to the control signal. The motor drive unit includes: a first switch unit for driving control of the first motor; a second switch unit for driving control of the second motor; and a third switch unit commonly used for the driving control of the first motor and the second motor. An objective of the present invention is to provide the electronic parking brake system capable of responding to a failure of a specific switch element, and a control method thereof.
