Abstract
An engine starting system and technique include selecting a target engine speed profile from a plurality of engine speed profiles based on operator inputs and operating parameters of the vehicle. A feedback control strategy is used to substantially conform the engine speed with the target speed profile during starting until a target speed is reached in which fueling is initiated to start the engine.
