摘要
A current control device sets a target current value of a solenoid, and sets a duty ratio of a PWM signal outputted to a drive circuit of a solenoid based on the target current value. The target current value is a value that periodically varies in a dither period longer than a PWM period of the PWM signal. A setting period of the target current value and a setting period of the duty ratio are shorter than the dither period. As compared with a configuration where the duty ratio is set in the dither period, a time period from a time a basic current value is changed to a time the duty ratio is renewed is shortened. A operation responsiveness of a movable core of the solenoid improves.
