To provide a solenoid valve control unit capable of reducing consumption of electric energy by preventing erroneous closing of a solenoid valve for a fluid while properly setting and correcting valve opening action holding force provided to the solenoid valve for fluid.

The solenoid valve control unit comprises an operation state judging means for judging operation state of a prime mover 1, and a valve opening state detecting means for detecting whether a solenoid valve 3 for fluid remains closed or not. A control means 18 performs holding force adjustment control to raise an electric power supplied to the solenoid valve 3 for a fluid so that valve opening action holding force increases as the vibration transmitted from the prime mover 1 to the solenoid valve 3 increases which is predicted according to the operation state of the prime mover 1 based on the judgment result by the operation state judging means. It performs holding force raising control to correct the supplied electric power corresponding to the operation state toward the increase side when the open valve state detecting means detects that the valve is closed while the supplied electric power corresponding to the operation state which is judged by the operation state judging means is supplied to the solenoid valve 3.
