Abstract

See full text

An apparatus and method control regenerative braking torque of an electric vehicle on which an anti-lock brake system (ABS) is mounted. The apparatus and method can compensate the regenerative braking torque of the driving motor based on the behavior model of the electric vehicle, such that the ABS is prevented from entering an operating range to the maximum limit to maximize the energy recovery rate through regenerative braking. The apparatus includes a disturbance extractor that extracts a disturbance in a specific frequency band from a difference between a behavior model and an actual behavior of the electric vehicle. The apparatus includes a torque compensator that compensates for the regenerative braking torque based on the disturbance extracted by the disturbance extractor.
