Abstract:
An injection control device for a fuel injection valve includes: a current detection unit of the fuel injection valve; a current area correction control unit that performs current area correction for an area correction amount of an energization time to equalize the integrated current value of the energization current profile and an integrated current value of the detected current; and an information correction unit that learns and stores a reference attainment time, from a start of energization to an attainment of each of the plurality of reference currents, in a storage unit, and corrects information related to the current area correction based on a difference between the reference attainment time and an actual attainment time from the start of energization to the attainment of each reference current.
