PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of learning injection characteristics during partial lift injection more frequently.SOLUTION: A control device 40 for controlling injection of fuel by a fuel injection valve 30 includes: a setting section 42 for setting a requested injection amount which is an injection amount requested with respect to the fuel injection valve 30; a division section 43 for dividing the requested injection amount set by the setting section 42 into a prescribed injection amount and an adjustment injection amount other than the prescribed injection amount; injection execution sections 44 and 48 for executing divided injection of adjustment injection in which fuel in the adjustment injection amount is injected by the fuel injection valve 30 and partial lift injection in which lifting of a valve element 33 is ended in a partial lift state before the valve element 33 of the fuel injection valve 30 reaches a full-lift position and the fuel in the prescribed injection amount is injected; and a learning section 45 for learning injection characteristics of the fuel injection valve 30 in partial lift injection. |
