Abstract
An apparatus including an engine control unit which is configured to: start to supply electricity to a starter motor and start measurement of a power supply period; supply electricity to a solenoid when an absolute value of a rpm difference between an rpm of the engine and an estimated rpm of a pinion gear determined from a rpm table based on the measured power supply period becomes smaller than a rpm difference threshold value at which the pinion gear and a ring gear can be engaged with each other; judge that the engine is self-resumed when the engine becomes a state capable of self rotation with only fuel supply in a case where the rpm of the engine is larger than the estimated rpm of the pinion gear; and finish supplying electricity to the starter motor and finish measuring the power supply period, and finish supplying electricity to the solenoid.
