Abstract
In a system for driving a starter with a pinion so that the starter rotates a ring gear coupled to a crankshaft of an internal combustion engine to crank the internal combustion engine during a drop of a rotational speed of the crankshaft by automatic-stop control of the internal combustion engine, a predictor predicts a future trajectory of the drop of the rotational speed of the crankshaft based on information associated with the drop of the rotational speed of the crankshaft. A determiner determines a timing of the driving of the starter based on the future trajectory of the drop of the rotational speed of the internal combustion engine.
