Abstract
A method is disclosed for estimating engine power output for an engine in a hybrid electric vehicle powertrain that includes an electric motor and an electric generator. Selected powertrain variables, including electric motor torque and electric generator torque, are used in determining desired vehicle traction wheel torque and an estimated engine power. A calibrated delay in calculating estimated engine power following a time sampling of the values for motor torque and generator torque avoid inertial effects.
