Disclosed herein are a solenoid valve control apparatus and method. The solenoid valve control apparatus to control a solenoid valve which include a solenoid coil and is opened and closed by current supplied to the solenoid coil, includes a switching unit which switches the current supplied to the solenoid coil, a pre-driver unit which outputs a driving signal to drive the switching unit, a current detection unit which detects the current flowing in the solenoid coil, and an MCU which controls the pre-driver unit so as to output the driving signal from the pre-driver unit to the switching unit such that a value of the current detected by the current detection unit reaches a target current value during current control of the solenoid valve and controls the pre-driver unit such that a frequency of the output driving signal is varied during output of the driving signal.
