1. An electric parking brake (EPB) system, comprising:
an EPB configured to provide a clamping force to a vehicle for parking; and
a controller configured to engage the EPB;
wherein the controller is configured to:
determine, during a parking operation of the vehicle, whether the vehicle is operating in a predetermined time immediately following a brake pad replacement based on a driving distance of the vehicle and brake pad replacement information of the vehicle, and
upon determining that the vehicle is operating in the predetermined time immediately following the brake pad replacement, compensate for a target clamping force of the EPB, and perform the parking operation based on the compensated target clamping force,
the controller compensates for a target clamping force by increasing the target clamping force of the EPB based on at least one of a number of parking operations of the EPB and the driving distance when compensating for the target clamping force.
