Abstract
It is possible to accurately estimate a starting current and calculate a precise starting minimum voltage without being influenced by a change in a storage battery state or a starting state by updating a current/voltage correlation characteristic corresponding to a deterioration state of a storage battery each time a current/voltage data set obtained when a starter is driven is newly stored in association with the deterioration state of the storage battery and by calculating the starting current corresponding to a present voltage immediately before start in accordance with the current/voltage correlation characteristic corresponding to the present deterioration state of the storage battery when determination is made as to whether or not to drive the starter.
