| description | Provided is an injector control device which is capable of setting a preceding injection amount to a fuel injection amount that is less than a main injection amount, while suppressing situations where preceding injections executed prior to a main injection in multi-stage injection are eliminated.An injector control device 2 includes: an injection amount setting unit 211 that sets, as a total injection amount, a total of fuel injection amounts in multi-stage injection in a single cycle, and sets, as a preceding injection amount, a fuel injection amount in a preceding injection executed prior to a main injection in the multi-stage injection; an energization period setting unit 212 that sets an energization period of an injector 31 based on the fuel injection amounts set by the injection amount setting unit 211; and an injector driving unit 213 that controls driving of the injector 31 based on the energization period set by the energization period setting unit 212. The injection amount setting unit 211 sets a fuel injection amount that is a predetermined percentage of the total injection amount as the preceding injection amount. |
