Abstract
A method and apparatus is provided for controlling the solenoid current of a solenoid valve which controls the amount of suction air in an internal combustion engine. A solenoid current control valve is calculated and a present time value of solenoid current is detected after which a deviation between the present time solenoid current and the solenoid current control value is calculated. A correction value for the present time solenoid current control value is calculated based upon the deviation and a corrected solenoid current control value is determined as a function of the present time solenoid current control value and the correction value.
