1. An emergency braking system configured to provide an emergency braking using an electronic parking brake (EPB) in case of total or partial failure of a main braking system, the emergency braking system comprising:
an EPB actuator configured to apply an emergency braking force to wheels;
a slip detection unit configured to detect a wheel slip on the wheels equipped with the EPB actuator; and
an EPB control unit configured to constantly determine a road surface condition by calculating a slip ratio through slip information transmitted from the slip detection unit, and to control an operation of the EPB actuator based on the road surface condition,
wherein an initial target braking force is set to a maximum braking force value of braking force values transmitted to the wheels from the main braking system prior to the emergency braking.
