Abstract
An apparatus of changing deceleration of a braking curve based on a variation in a coefficient of friction may include: a coefficient-of-friction calculating unit calculating a first coefficient of friction between a brake disk and a friction material at a first point in time, and calculating a second coefficient of friction between the brake disk and the friction material at a second point in time at which a preset driving distance has elapsed from the first point in time; a determination unit determining whether there is a change in coefficient of friction between the first coefficient of friction and the second coefficient of friction; and a deceleration changing unit changing deceleration by regenerative braking or deceleration by hydraulic braking from a preset braking curve by an amount of a variation in deceleration according to the variation in coefficient of friction, when there is a variation in coefficient of friction.
