Electromagnetic valve driving device

Abstract

An electromagnetic valve driving device that controls an energization period to a solenoid coil provided in a fuel injection valve and causes the fuel injection valve to inject fuel a plurality of times during one combustion cycle of an internal combustion engine, the electromagnetic valve driving device includes: a storage that stores a correction amount map indicating a relationship between an energization pause period from a completion time of a first-half energization period, which is the energization period for a first fuel injection in the one combustion cycle, to a start time of a later-half energization period, which is the energization period for next fuel injection, and a correction amount for the later-half energization period; an energization period correction unit that obtains the correction amount from a command value of the energization pause period based on the correction amount map and corrects the later-half energization period based on the obtained correction amount; and an energization controller that energizes the solenoid coil based on a later-half correction energization period that is the later-half energization period corrected by the energization period correction unit.
