A control system for an electrified powertrain of an electrified vehicle includes a controller configured to determine a regenerative torque request and a friction braking torque request to collectively satisfy a braking torque request indicative of a desired braking torque to be applied to a driveline of the electrified vehicle and, when the regenerative torque request is greater than zero, obtain a driveline model configured to model transient dynamics of the driveline including a driveline shaft connected between friction brakes of the electrified vehicle and an electric motor of the electrified powertrain, adjust a motor torque command for the electric motor based on the regenerative torque request, the model, and the speeds and/or positions of the electric motor and the driveline shaft, and control the electric motor based on the motor torque command to perform regenerative braking and thereby improve vehicle regenerative braking performance and/or vehicle drivability.
