PROBLEM TO BE SOLVED: To provide an injector control device can highly accurately control valve opening time of an injector with simple configuration.SOLUTION: A clamp circuit 44 is provided, which has a Zener diode 44a disposed between a gate and a drain of a third transistor 43 and clamps a voltage between the gate and the drain with clamping voltage Vcl. When correcting clamping voltage Vcla measured after the third transistor 43 is turned OFF is lower than a reference voltage, an injection set period of time T is corrected to be shorter than a reference period of time To, and when the correcting clamping voltage Vcla is higher than the reference voltage, the injection set period of time T is corrected to be longer than the reference period of time To. |
