A control device (10) for controlling actuation of an injector (IJ) disposed in an internal combustion engine is provided with: a voltage impressing unit (300) that impresses a voltage stepped-up to a step-up target value on the injector in order to cause the injector to open a valve; a current measurement unit (400) that measures a drive current supplied to the injector in association with the impressing of the voltage; and a computation unit (210) that calculates a current difference value (DF) that is a value indicating the difference between an actual measurement profile that represents the change over time in actually measured values of the drive current and a reference profile that has been set in advance. The step-up target value is corrected on the basis of the calculated current difference value. |
