Abstract
A solenoid valve control system controlling a solenoid valve which changes a solenoid valve state between an opened state and a closed state by applying pulsed electric power thereto. The solenoid valve control system includes an ammeter for detecting a current value applied to the solenoid and a control device for controlling electric power supplied to the solenoid. The control device has a duty control section which controls an ON-OFF ratio of pulsed electric power repeatingly applied to the solenoid and a correcting section which corrects an output from the duty control section according to the current value detected by the ammeter. Therefore, the line pressure is kept at a precise target value.
