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; a fuel injection quantity correction unit that calculates an air-fuel correction amount and corrects the command value for the fuel injection quantity; 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. The injection control device further includes a learning controller that stops the air-fuel learning.
