ABSTRACT:
A duty ratio for operating a solenoid is determined by calculating a duty ratio in each of basic periods and determining an operational time for which the solenoid is to be operated within each of the basic periods, based on the calculated duty ratio. When the duty ratio is reduced to the extent that the operational time is shorter than a minimum possible time of operation of the solenoid, an operational time for which the solenoid is to be operated is determined within a new period composed of a plurality of consecutive basic periods.
