Patent ID: 8160761

Claim:
Method for controlling a powertrain system including an engine and an electric machine mechanically coupled to an electro-mechanical transmission to transfer power to an output member, the method comprising: monitoring an accelerator pedal position; monitoring speed of the output member; determining an acceleration of the output member; determining a future time instant comprising a point in time after a predetermined elapsed time interval from a present time, the predetermined elapsed time interval comprising an elapsed time for executing a control scheme associated with controlling the powertrain; predicting the accelerator pedal position for the future time instant based upon a filtered accelerator pedal position and a time-based derivative of the accelerator pedal position; predicting the speed of an output member for the future time instant based upon the speed and the acceleration of the output member; and predicting an operator torque request for the future time instant based upon the predicted speed of the output member and the predicted accelerator position for the future time instant.
