Current control means for solenoid storage medium which stores a program for controlling a current of a solenoid, and method for controlling a current of a solenoid

A current control means provides a current target value (It) of a solenoid, and sets a duty cycle (Rd) of a PWM signal (Spwm) a, which is output to a drive circuit of a solenoid, based on the current target value (It). The current target value (It) is a value in a dither period (Td) which is longer than a PWM period (Tpwm) of the PWM signal (Spwm) periodically changes. A setting period (T1) of the current target value (It) and a setup period (T2) the duty cycle (Rd) are shorter than the dither period (Td). In comparison with a configuration in which the duty cycle is set in the dither period, a time period from a time, is changed to the a basic current value (Ib) to a time at which the duty ratio (Rd) is renewed shortened , A Operationsansprechempfindlichkeit a movable core of the solenoid is improving.
