  "textContent": "Provided is a solenoid valve control device capable of detecting a motion of a valve body in response to a drive command without adding a special circuit. According to the present invention, a solenoid valve control device controls opening and closing of a solenoid valve in an internal combustion engine system including: a fuel pump including a plunger that that increases or decreases a volume of a pressurizing chamber by moving up and down with rotation of a pump drive cam, a solenoid valve for sucking fuel into the pressurizing chamber, and a discharge valve for discharging fuel in the pressurizing chamber; and a fuel rail (common rail) that accumulates fuel discharged by the fuel pump. The solenoid valve control device includes a control unit that determines whether or not closing of the solenoid valve has succeeded based on fuel pressure of the fuel rail, or calculates a discharge amount by closing the solenoid valve based on the fuel pressure of the fuel rail.",
