A method for detecting variations between the quantities of fuel injected into cylinders by fuel injection devices and correcting the fuel injection quantity variation while minimizing the computational load on a drive device and the level of performance required of a pressure sensor includes a drive device for fuel injection control, wherein movable valves are driven so that predetermined quantities of fuel are injected by applying, for the duration of a set energization time, a current that will reach an energization current to solenoids of a plurality of fuel injection devices which open/close fuel flow paths. The drive device is characterized in that the set energization time or energization current is corrected on the basis of a pressure detection value from a pressure sensor that is attached to a fuel supply pipe disposed upstream of the plurality of fuel injection devices.
