Abstract

A method is disclosed for controlling an internal combustion engine in a vehicle powertrain. A filtered driver demand for torque at vehicle traction wheels is used to determine an engine torque command. The engine torque command is initialized to a percentage of a target engine torque as a function of variables that may include a smoothness factor.
