Claim 5:
6. An injection control device configured to open and close a fuel injection valve by driving the fuel injection valve with a current to control fuel injection to an internal combustion engine, the injection control device comprising:
a booster circuit configured to boost a battery voltage;
a boosting control circuit configured to perform boosting control on the booster circuit; and
a computer configured to set charge permission or charge prohibition for the booster circuit to the boosting control circuit, wherein:
the computer is configured to set the charge permission or the charge prohibition for the booster circuit to the boosting control circuit according to an injection type,
the injection control device further comprises an injection type determination unit configured to determine the injection type, and
the computer sets the charge prohibition to the boosting control circuit when the injection type determination unit determines that the injection type is a learning minute injection, the learning minute injection being an injection that does not contribute to the driving of the internal combustion engine.
