A duty solenoid valve control apparatus and a duty solenoid valve control method, in which a plurality of duty solenoid valves different in operation from each other are controlled without increase of the program capacity of a computer. The apparatus comprises a duty signal generating device for generating a duty signal corresponding to a time ratio, an overexcitation signal generating device for generating an overexcitation signal to overexcite a solenoid coil, a holding signal generating device for generating a holding signal to hold a duty solenoid valve, and a signal synthesizing device for synthesizing the duty signal, the overexcitation signal and the holding signal into a drive signal for driving the solenoid coil.
