Disclosed are an electronic parking brake system and a safety control method thereof. The electronic parking brake system comprises: a first parking brake including a first electric motor which provides a first braking torque to a first wheel of a vehicle; a second parking brake including a second electric motor which provides a second braking torque to a second wheel of the vehicle; a first control unit controlling the first electric motor; and a second control unit controlling the second electric motor. Based on a fact that the first control unit transmits a first signal to the second control unit at a predetermined period, and the secon control unit does not receive the first signal from the first control unit, the second braking torque provided to the second wheel can be increased. Provided are the electronic parking brake system, capable of reducing a load on the parking brake, and the safety control method thereof.
