Abstract
An injection control device includes an injection controller that is configured to control a fuel injection valve, which is current-driven by a charging voltage obtained by boosting a battery voltage, to perform fuel injection a plurality of times for each cylinder. The injection controller is configured to prohibit learning or adjust an injection when the charging voltage does not reach a predetermined determination voltage.
Claims8
An injection control device comprising:
- an injection controller configured to control a fuel injection valve, which is current-driven by a charging voltage obtained by boosting a battery voltage by charging a capacitor, to perform fuel injection a plurality of times for each cylinder, wherein
- the injection controller is configured to
- detect a boosting time required for the charging voltage to reach a target voltage,
- calculate a boosting capability, which indicates an amount of energy stored in the capacitor per unit time, using the boosting time,
- learn the boosting capability by storing the boosting capability, and
- prohibit learning of the boosting capability when the charging voltage does not reach a predetermined determination voltage.
