Abstract
Method for voltage stabilization during an engine starting event of a vehicle includes receiving, at a switch device module, an active Start_ON signal from a starter solenoid module indicating initiation of the engine starting event. At the switch device module, an auxiliary electrical energy storage device (ESD) is electrically coupled to one or more auxiliary loads within a predetermined delay since the active Start_ON signal was received. A primary ESD and a starter motor are electrically decoupled from the one or more auxiliary loads only after the auxiliary ESD has been electrically coupled to the one or more auxiliary loads. In response to a predetermined condition occurring while the primary ESD and the starter motor are electrically decoupled from the one or more auxiliary loads, the primary ESD and the starter motor are electrically coupled to the one or more auxiliary loads.
