Abstract
A vehicular powertrain system includes an engine, an electro-mechanical transmission and an electric machine arranged in an input-split hybrid configuration. A control system for the powertrain system includes a control module signally connected to a plurality of input devices and configured to execute program code stored on a computer readable medium to control the powertrain. The program code monitors operator inputs, determines an intent to service the vehicle based upon the operator inputs, commands the electric machine to generate a net torque output of zero, and controls the engine speed correlative to an operator depression of an accelerator pedal.
