Abstract
An engine startup system for a vehicle includes: a cold start module configured to selectively generate a cold start command when an ambient air temperature is less than a predetermined temperature; a starter control module configured to, in response to the generation of the cold start command, engage a starter motor with a crankshaft of an engine and apply power from a first battery to the starter motor; and a belt alternator starter (BAS) control module configured to: not apply power from a second battery to a BAS after the generation of the cold start command until an engine speed of the engine is greater than a first predetermined speed; and in response to a determination that the engine speed of the engine is greater than the first predetermined speed, apply power from the second battery to the BAS and further increase the engine speed of the engine.
