Abstract
In a current-driving of a fuel injection valve to inject fuel through a single injection or a multi-stage injection, an energization time correction amount is calculated by performing area correction on a current flowing through the fuel injection valve. The single injection is switched to the multi-stage injection when the single injection is consecutively performed under a predetermined condition.
