Fuel injection control device

Abstract

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 127 that controls a plurality of fuel injection valves having a coil for energization, including a valve body operation time detection unit 211 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 213 that corrects a drive current parameter of the fuel injection valve based on the valve closing completion time, an injection pulse width correction unit 214 that corrects an energization time of the fuel injection valve based on the valve closing completion time, and a correction method selection unit 212 that selects at least one of the drive current correction unit 213 and the injection pulse width correction unit 214 to execute correction based on a state of an engine.
