Abstract
An invention that judges whether an engine is being cranked by a starter based on the conditions that a prior cranking control has ended, the engine rotates at or less than a limit rotation velocity leading to an engine stall, and a battery voltage falls to or below a predetermined value. When such conditions are met, then engine cranking control is started. The engine can be shifted to the cranking control without an input signal from a starter switch and the engine can be promptly cranked.
