| description | An injector driving device includes a control circuit of a booster circuit that charges a capacitor by repeatedly switching a booster switch ON/OFF during a voltage boost control to cause a reverse voltage in a coil, and stops the voltage boost control upon determining that a capacitor voltage has reached a corrected target value. The control circuit detects a peak value of the capacitor voltage during an OFF period of the boost switch. The control circuit also detects a capacitor voltage as an ON value during the subsequent ON period of the booster switch. A difference between the peak voltage and the ON value of the capacitor is calculated, and a post-correction target value is set by adding the difference to a reference value of a target value. |
