<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of achieved in the highly accurate estimation of a fuel injection amount, and thereby to enable the highly accurate correction of the fuel injection amount according to a deterioration state of a fuel injection valve. <P>SOLUTION: The fuel injection control device controlling a fuel injection valve includes: a valve opening timing detection means detecting the predetermined number of the valve opening timing of the fuel injection valve; an averaging means averaging the valve opening timing within a predetermined range from a median of the detected predetermined number of the valve opening timing; a fuel injection amount estimating means estimating the fuel injection amount based on average valve opening timing acquired by averaging the valve opening timing; and a correction control means performing the correction control of the fuel injection amount when the estimate of the fuel injection amount is compared with a default of the fuel injection amount acquired in advance, and a relation between them satisfies a correction executing condition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
