Abstract

A system and a method for estimating regenerative braking of a vehicle are provided to correct allowable regenerative braking and braking linearity by estimating allowable regenerative braking in consideration of a current status of a battery and a motor. The system for estimating allowable regenerative braking for a vehicle, includes: a motor control unit to provide a charging power limit of a motor as a first input; a battery management system to provide a charging power limit of a battery as a second input; an active hydraulic brake to input allowable regenerative braking as a third input; and a hydraulic control unit to estimate final allowable regenerative braking using the charging power limit of the battery, the charging power limit of the motor, and the allowable regenerative braking as the inputs.
