Abstract
Provided is a solenoid valve drive device capable of accurately controlling a hysteresis value of a drive current for driving a solenoid valve. The solenoid valve drive device according to the present invention controls a set value of a hysteresis or a time width of the hysteresis based on a difference between an extreme value of the hysteresis in a peak hold period of a drive current and a set value of the extreme value.
