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.
Claims8
An injection control device comprising:
- an injection command unit that executes a current-drive of a fuel injection valve to inject fuel through a single injection or a multi-stage injection;
- an area correction unit that calculates an energization time correction amount by performing area correction on a current flowing through the fuel injection valve when the injection command unit controls the fuel injection valve to inject the fuel through the single injection or the multi-stage injection;
- and
- a multi-stage injection switch unit that switches from the single injection to the multi-stage injection when the single injection is consecutively performed under a predetermined condition.
