Document Type and Number:
WIPO Patent Application WO/2024/024078
Kind Code:
A1
Abstract:
Provided is a solenoid control device capable of performing control to suppress generation of loud sound from a solenoid. A solenoid control device (170) controls a solenoid (130) that comprises a coil (31), a movable magnetic pole portion (132), and an opposing portion (133). The movable magnetic pole portion (132) is displaced so as to be moved in a direction toward the opposing portion (133) or a direction away from the opposing portion (133). The solenoid control device (170) comprises a control unit (172) that controls a current delivered to the coil (31). The control unit (172) performs a current-increasing control to adjust the current that flows through the coil (31) so that the value of the current through the coil (31) gradually increases in an initial period before the movable magnetic pole portion (132) starts to move in the direction away from the opposing portion (133).
