Abstract
A fuel injection control device includes a correction unit to calculate a correction coefficient for correcting a valve closing timing detected by an electromotive force quantity detection mode by using a valve closing timing detected by a timing detection mode. An estimation unit estimates an estimated injection quantity by using a valve closing timing after corrected by using a correction coefficient when the electromotive force quantity detection mode is selected by a selection unit and a valve closing timing is detected by the electromotive force quantity detection mode.
