Abstract
An adaptive feedforward control method for an electrified powertrain including a torque converter includes determining a desired input speed for a torque converter based on the set of operating parameters of the electrified powertrain, determining minimum and maximum torques for an impeller of the torque converter based on the set of operating parameters of the electrified powertrain, determining a raw feedforward torque for the torque converter impeller based on the desired input speed for the torque converter and a speed of a turbine of the torque converter, determining a final feedforward torque for the torque converter impeller based on the raw feedforward torque for the torque converter impeller and the minimum and maximum torques for the torque converter impeller, and controlling an electric motor of the electrified powertrain based on the final feedforward torque for the torque converter impeller.
