1. A method for brake force compensation for a brake apparatus of a vehicle, the method comprising:
determining, by a controller, hydraulic brake torque required for hydraulic braking of the brake apparatus according to a driver's request brake torque;
converting, by the controller, the hydraulic brake torque into a brake hydraulic pressure by use of a torque factor which is a friction capability of a brake friction material in the hydraulic brake torque;
determining, by the controller, a correction amount of the torque factor according to a season and a bushing degree of the brake friction material, which influences a friction coefficient of the brake friction material which is an element of the torque factor, so as to determine a target hydraulic brake torque; and
controlling the brake apparatus according to the determined target hydraulic brake force.
