Abstract:
Provided is a solenoid control device capable of providing control in which production of loud sounds by a solenoid is suppressed. A solenoid control device (170) controls a solenoid (130) that: has a coil (31), a mobile magnetic pole section (132), and an opposing section (133); and in which the mobile magnetic pole section (132) displaces so as to move in a direction towards the opposing section (133) and a direction away from the opposing section (133). The solenoid control device (170) has a control unit (172) that controls the current flowing to the coil (31) and performs speed control for adjusting the current flowing to the coil (31) such that the speed of the mobile magnetic pole section (132) reaches a target speed during at least part of the period from the start of movement of the mobile magnetic pole section (132) until the stop of movement thereof.
