Abstract
An injection control device includes: a boost controller performing a boost switching control of a boost switch to charge a boost capacitor and supplying a boost power from a battery power supply; a boost voltage monitor monitoring the boost voltage; and a boost monitor timing controller setting a section from a predetermined time after an on-edge of the boost switch to an off-edge timing in a section monitor mode as a boost monitor section. The boost controller stops boosting by stopping the boost switching control when the boost voltage is equal to or higher than a boost stop threshold value in the boost monitor section.
