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 either belt/chain tensioner position or the position of the belt/chain itself to determine when the IC engine has achieved self-sustaining operation and signal the starter/alternator to transition from start-up to generator mode.
