Abstract
A method for controlling a demand for engine power in a control for an engine in a hybrid electric vehicle with power-split characteristics. Following transitions from acceleration or deceleration operating modes to a steady-state operating mode, power demand excursions from road-load power are attenuated or avoided by filtering the power demand using a filter constant that changes within battery power constraints as a function of a normalized driver demand for power at traction wheels for the vehicle.
