Abstract

The present invention is directed to determining and controlling the appropriate moment at which a combined starter/alternator should transition from start-up mode to alternator/generator mode following an IC engine start-up sequence. The method relies on starter/alternator motor phase voltage or motor phase current monitoring to establish the timing of the transition.
