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.
本发明涉及用于控制电动车辆的再生制动扭矩的装置及方法。所述电动车辆安装有防抱死制动系统(ABS)。所述装置和方法可以基于电动车辆的行为模型来补偿驱动电机的再生制动扭矩,从而最大限度地防止ABS进入运行范围,以使通过再生制动的能量回收率最大化。所述装置包括扰动提取器,该扰动提取器从电动车辆的行为模型与实际行为之间的差异中提取特定频带的扰动。所述装置包括扭矩补偿器,该扭矩补偿器基于由扰动提取器提取的扰动来补偿再生制动扭矩。
