December 29, 2022
An injection amount variation of a plurality of fuel injection valves is reduced regardless of a state of an engine. According to one aspect of the present invention, there is provided a fuel injection control device that controls a plurality of fuel injection valves having a coil for energization, including a valve body operation time detection unit that detects a valve closing completion time from an end of energization of the fuel injection valve to completion of valve closing of a valve body of the fuel injection valve, a drive current correction unit that corrects a drive current parameter of the fuel injection valve based on the valve closing completion time, an injection pulse width correction unit that corrects an energization time of the fuel injection valve based on the valve closing completion time, and a correction method selection unit that selects at least one of the drive current correction unit and the injection pulse width correction unit to execute correction based on a state of an engine.
