FUEL INJECTION CONTROL DEVICE

A fuel injection control device includes a valve closing detection unit () to detect a valve closing timing by using either of an electromotive force quantity detection mode and a timing detection mode, a selection unit () to select either of the electromotive force quantity detection mode and the timing detection mode for detecting the valve closing timing, and a correction unit () to calculate a correction coefficient for correcting a requested injection quantity so as to reduce the difference between an estimated injection quantity and the requested injection quantity, and the selection unit selects the electromotive force quantity detection mode regardless of the value of the requested injection quantity when the calculation of the correction coefficient is not completed.
