Claim:
1. A method, comprising: maintaining a plurality of engine speed profiles for starting an internal combustion engine of a vehicle; selecting a target engine speed profile from the plurality of engine speed profiles based on operator inputs from an operator of the vehicle and operating parameters of the vehicle, wherein selecting the target engine speed profile further includes determining an engine crank revolution count provided by the target engine speed profile satisfies a minimum crank revolution count before starting the engine; driving the internal combustion engine with a starter motor in response to selecting the target engine speed profile; determining an instantaneous engine speed during the starting duration; regulating the speed of the internal combustion engine during the starting duration in response to the instantaneous engine speed to substantially conform the speed of the internal combustion engine with the target speed profile; and starting the internal combustion engine in response to the speed of the internal combustion engine reaching a target speed of the target speed profile.
