Abstract
An injection control device opens and closes 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 includes: a booster circuit that boosts a battery voltage; a boosting control unit that performs boosting control on the booster circuit; and a charge control setting unit that sets charge permission or charge prohibition for the booster circuit to the boosting control unit.
Claims6
