Abstract
A control method for vehicular hybrid powertrain system includes monitoring operator inputs to an accelerator pedal and a transmission gear selector, and determining an operator torque request based upon the operator inputs to the accelerator pedal and the transmission gear selector. Torque output from the electric machine is commanded based upon the operator torque request. Engine output is controlled based upon the operator torque request and the commanded torque output from the electric machine. Vehicle hood position is monitored and the engine output is controlled correlative to the operator input to the accelerator pedal when the monitored position of the vehicle hood is open and the operator input to the transmission gear selector is one of a PARK and a NEUTRAL position.
