Abstract:
A fuel injection control device for an internal combustion engine which is applied to a fuel injection system of the internal combustion engine, the fuel injection system including fuel injectors, driving circuits that drive the fuel injectors in each of driving systems into which the fuel injectors are divided, and current detection circuits that are provided to the driving systems, respectively, and the current detection circuits that sense driving currents of corresponding fuel injectors. The fuel injection control device includes an acquisition unit to acquire a current change parameter that is a parameter correlative to a change quantity of a sensed current per unit time in each of the driving systems, and a current correction unit to execute a current correction in at least one of the driving systems based on the current change parameter in each of the driving systems.
