Abstract
An injection control device includes: a fuel injection quantity command value output unit that outputs a command value for a fuel injection quantity of a fuel injection valve; and a controller that executes current control on the fuel injection valve. The controller executes current area correction by calculating an area correction amount for an energization time to cause an integrated current value of an energization current profile and the integrated current value of a current to be equal to each other. Correction control of the current area correction is changed based on a detection signal of a cooling water temperature of an internal combustion engine.
