Fuel Injection Control Device and Fuel Injection Control Method

Appropriate detection of an abnormality of voltage information, which is a basis for correcting a fuel injection amount, becomes possible. For this reason, a fuel injection control device which has a drive IC controlling a fuel injection drive unit to supply a high voltage to a solenoid so as to open a fuel injection valve and controlling the fuel injection drive unit to supply a low voltage to the solenoid so as to hold a valve-open state of the fuel injection valve includes: a drive voltage input unit that measures and outputs voltage information based on an upstream voltage of the solenoid of the fuel injection valve and a downstream voltage of the solenoid a fuel injection amount correction unit that corrects a fuel injection amount of the fuel injection valve based on the voltage information output from the drive voltage input unit and a voltage input function abnormality detection unit that detects whether an output of the drive voltage input unit is abnormal based on the voltage information output from the drive voltage input unit
